The present disclosure relates to patient care. More particularly, the present disclosure relates to a system, method, and apparatus for electronic patient care.
Providing patient care in a hospital generally necessitates the interaction of numerous professionals and caregivers (e.g., doctors, nurses, pharmacists, technicians, nurse practitioners, etc.) and any number of medical devices/systems needed for treatment of a given patient. Despite the existence of systems intended to facilitate the care process, such as those incorporating electronic medical records (“EMR”) and computerized provider order entry (“CPOE”), the process of providing comprehensive care to patients including ordering and delivering medical treatments, such as medications, is associated with a number of non-trivial issues.
In an exemplary embodiment involving the ordering and administration of medications, the electronic patient care system may comprise a first data-gathering module (e.g., a monitoring client) and a second order-input module (e.g., a fixed or portable monitoring client) having a user interface for transmitting an order or receiving patient-related information. The first module may be configured to receive and store measured parameters pertaining to a patient's current condition (i.e., patient-condition parameters), such as blood pressure, heart rate, heart rhythm, temperature, oxygenation, respiratory rate, or ventilation, for example. The first module may also be configured to receive information about pre-existing parameters related to the patient from a first database (e.g., an EHR database containing information about the patient), for example, including patient-condition parameters such as medication allergies or sensitivities, other currently administered medications presently in the patient's tissue, age, weight, height, kidney, or liver function. The first module may also be configured to obtain medication information about the ordered medication and/or pre-existing medications from a second database (e.g., a drug information database), such as known medication interactions, effects of the medication or pre-existing medications on blood pressure, pulse, heart rhythm, or respirations, for example. The first module can be configured to compare the patient's currently-measured, patient-condition parameters and received, pre-existing, patient-condition parameters with known normal ranges, and create a table of patient-condition parameters found to be outside the normal ranges. The first module may then compare the table of patient-condition parameters with a table of corresponding parameters obtained from the drug information database. If a match is found to exist between the table of patient-condition parameters and the table of corresponding parameters, the first module may then retrieve one or more pre-entered and stored messages for transmission to the second (order input) module. These messages may include, for example, warnings to a user of the second module that are appropriate for the particular medication ordered, the patient's pre-existing medications, and the patient's current and pre-existing medical condition. Optionally, further repetitions of warnings may be avoided once a warning has been received by the second module, and the warning has been acknowledged by the user of the second module through an input signal from the user interface.
In other embodiments, the electronic patient-care system may provide the user with editable default values derived from standard dosing and administration guidelines obtained from the drug information database, and can alert the user to modifications that may be indicated based on the patient's current and pre-existing medical condition, allergies, existing medications, or other patient-condition parameters. The electronic patient-care system preferably minimizes the amount of typed input from a user.
In other embodiments, the first module or other modules of the electronic patient-care system may also be used to identify ordered medications to be delivered to the patient's bedside (through the use of, for example, bar codes and readers, or RFID tags and scanners), and verify that the appropriate medication and dosage are being prepared and delivered to the patient. In an embodiment, the first module may also interact through a wired or wireless communications link with a patient-care device that administers treatment, such as an infusion pump or pill dispenser. In the case of an infusion pump, the first module or another connected module may provide the infusion pump with patient-treatment parameters, such as infusion settings including an infusion rate or infusion pressure, and receive from it various operating parameters, such for example, the presence of air in the infusion line, the amount of solution remaining in an IV bag to which it is connected, or the pressure of fluid in the infusion line. If the operating parameters are found to be abnormal, the first module may be configured to respond by signaling the infusion pump to halt infusion, respond by signaling a mechanical occlude to occlude the IV line, alter the infusion rate, and/or alert a health care provider or others of the abnormality, either directly through an alarm incorporated in the first module, or by transmission of an alarm to the second module. In a further embodiment, the first module may also be configured to communicate with various patient-care devices used to monitor a patient's condition and determine patient-condition parameters, such as, for example, blood pressure monitors, ECG monitors, pulse oximetry monitors, temperature monitors, and the like. The various parameters monitored by be monitored and/or logged by a mobile device and/or within an EMR. In some cases, the first module can be programmed to emit an alert to the patient or other persons if the monitored patient-condition parameters fall outside a predetermined range. In some embodiments, the first module can transmit a signal to a monitoring client to conduct an unscheduled measurement by the patient-care device to obtain another patient-condition parameter. The first module may communicate with various health care providers at various locations, and in an embodiment may be able to notify the patient to whom it is assigned of an abnormality, and recommend corrective action through, for example an audible alert or recorded message.

General Overview
As previously described the process of providing comprehensive care to patients, such as ordering and delivering of medical treatments, is associated with a number of non-trivial issues. For instance, there is great potential for critical information to be not properly communicated, treatment decisions to be made without ready access to complete information, and/or delay in implementation of prescriptions due to unnecessarily redundant and inefficient procedures.
In more detail, medication errors may be responsible for hundreds of deaths and may injure thousands or even millions of people each year in the United States alone. Hospitals under financial stress may experience an increased incidence of medication errors. Medications associated with the most dangerous errors include insulin, narcotics, heparin, and chemotherapy. Sources of medication errors include administering the wrong medication, administering the wrong concentration of medication, delivering the medication at the wrong rate, or delivering the medication through the wrong route (medications can be administered orally, intravenously, intramuscularly, subcutaneously, rectally, topically to the skin, eye or ear, intrathecally, intraperitoneally, or even intravesically). Even with proper ordering and proper labeling, medications may still be administered improperly because of illegible handwriting, miscommunication of prescriptions for medications, and mispronunciation of medications having similar names. The trend of using electronic medical records (“EMR”) and bar coding systems for medications has been shown to reduce the incidence of medication errors. EMR systems, for example, can facilitate computerized provider order entry (“CPOE”) and flag prescriptions that do not match a patient's diagnosis, allergies, weight, and/or age. However, these systems have not been widely adopted and their implementation can result in significant delays and inefficiencies in ordering, preparing, and administering medications.
In addition, medication infusion devices, e.g., infusion pumps, are involved in a substantial number (e.g., up to one third) of all medication errors that result in significant harm. The wrong medication may be hung, incorrect parameters (e.g., medication concentration or infusion rate) may be entered, or existing infusion parameters may be improperly changed. Of the deaths related to infusion pumps, nearly half may be due to user error and most of these errors may be due to errors in programming the infusion pump.
An effective monitoring system may monitor and intercede at any phase of the medication ordering and administration process to help minimize any of a number of adverse events that could result from the treatment. The medication treatment process may be conceptually separated into three phases: a prescription phase, a medication preparation phase, and a medication administration phase. Errors can occur when a prescription for a medication is written or entered, when the medication is retrieved for use or mixed in a solution, or when the medication is administered to the patient.
Thus, in accordance with an embodiment of the present disclosure, an electronic patient-care system is disclosed that includes a monitoring client configured to communicate at least one patient-care parameter, a patient-care device configured to communicate the at least one patient-care parameter, and a communication interface configured to facilitate communication between the monitoring client and the at least one patient care device, by discovering the presence of the at least one patient-care device and translating communication signals from that device into a communication protocol associated with the monitoring client. In some embodiments, the monitoring client passively monitors the operation of a patient-care device. The communication interface may be implemented by a communication module described below. The communication interface may be further configured to discover the presence of additional other patient-care devices that are different from one another (e.g., diverse manufacturers, functions, and/or communication protocols, etc), and to translate communication signals from those devices into the communication protocol associated with the monitoring client or a hub. Thus, the communication interface allows the monitoring client, such as a tablet computer, to effectively be used as common generic user interface that healthcare providers can use when providing treatment to a patient associated with the monitoring client. One or more databases accessible by the monitoring client allow for central storage of patient info (in any format and database structure, as desired by the healthcare facility or database maintainer), as well as for downloading information that can be used by the healthcare providers in treatment of the patient associated with the monitoring client. The communication interface can be implemented in a number of ways, using wired and/or wireless technologies, and allows for seamless communication and failsafe operation of multiple patient-care devices. Some patient-care devices, hubs, docks, and/or monitoring clients may communicate simultaneously over two or more communications links and/or simultaneously over two frequency channels (in some embodiments, the data may be redundant). In some embodiments, the communication module may allow a patient-care device to be portability used, e.g., by including a battery and sufficient circuitry for mobile operation of the patient-care device, such as an infusion pump. Additionally or alternatively, a patient wristband may include batteries that can plug into the communication module to power the patient-care device (or in some embodiments, it may be plugged directly into the patient-care device). The communication module may be wirelessly charged.
In some embodiments, data such as patient-care parameters (e.g., real-time parameters, in some embodiments) may be transmitted to a cloud server for storage and may be de-identified.

The information within the barcode, RFID tag, and/or data may include the treatment regime, prescription, and/or patient information.
The automated compounding device may: (1) attach the barcode to the infusion pump 7, the syringe pump 126, the microinfusion pump 130, the pill dispenser 128, or the IV bag 170; (2) attach the RFID tag to the infusion pump 7, the syringe pump 126, the microinfusion pump 130, the pill dispenser 128, or the IV bag 170; and/or (3) program the RFID tag or memory within the infusion pump 7, the syringe pump 126, the microinfusion pump 130, the pill dispenser 128, or the IV bag 170 with the information or data. The data or information may be sent to a database (e.g., the patient's EHR 19 or the patient's personal EHR 19′) that associates the prescription with the infusion pump 7, the syringe pump 126, the microinfusion pump 130, the pill dispenser 128, or the IV bag 170, e.g., using a serial number or other identifying information within the barcode, RFID tag, or memory.
The infusion pump 7, the syringe pump 126, the microinfusion pump 130, or the pill dispenser 128 may have a scanner (e.g., an RFID interrogator or barcode scanner) that determines: (1) if the syringe pump 126 or the IV bag 170 has the correct fluid; (2) if the microinfusion pump 130 has the correct fluid; (3) if the pill dispenser 128 has the correct pills; (4) if the treatment programmed into the infusion pump 7, the syringe pump 126, the microinfusion pump 130, or the IV bag 170 corresponds to the fluid within the syringe pump 126, the microinfusion pump 130 or IV bag 170; (5) if the treatment programmed into the pill dispenser 128 corresponds to the pills within the pill dispenser 128; and/or (6) if the treatment programmed into the infusion pump 7, the syringe pump 126, the microinfusion pump 130, or the pill dispenser 128 is correct for the particular patient (e.g., as determined from a patient's barcode, RFID, or other patient identification). That is, in some specific embodiments, the infusion pump 7, the syringe pump 126, the microinfusion pump 130 and/or the pill dispenser 128 may read one or more serial numbers off of an RFID tag or barcode and ensure that the value matches a value as found in internal memory (e.g., downloaded via the automated compounding device, for example) or that the value matches a value as found in electronic medical records of a patient (e.g., via a patient's serial number as determined by a scan of an RFID tag of a patient or a scan of a barcode by the patient as stored in the patient's EHR 19 or the patient's personal EHR 19′).
For example, the scanner of the infusion pump 7, the syringe pump 126, the microinfusion pump 130, or the pill dispenser 128 may scan a barcode of another patient-care device to obtain a serial number of the patient care device and a patient's barcode to determine a serial number of the patient, and may query the electronic medical records data to determine if the serial number of the patient-care device corresponds to the serial number of the patient as stored within the electronic medical records (e.g., which may have been updated by the pharmacy 22 or the automated compounding device of the pharmacy).
Additionally or alternatively, the monitoring client 6 may scan the infusion pump 7, the syringe pump 126, the pill dispenser 128, the microinfusion pump 130, or the IV bag 170 to determine: (1) if the syringe pump 126 or the IV bag 170 has the correct fluid; (2) if the microinfusion pump 130 has the correct fluid; (3) if the pill dispenser 128 has the correct pills; (4) if the treatment programmed into the infusion pump 7, the syringe pump 126, the microinfusion pump 130, or the IV bag 170 corresponds to the fluid within the syringe pump 126, the microinfusion pump 130 or IV bag 170; (5) if the treatment programmed into the pill dispenser 128 corresponds to the pills within the pill dispenser 128; and/or (6) if the treatment programmed into the infusion pump 7, the syringe pump 126, the microinfusion pump 130, or the pill dispenser 128 is correct for the particular patient (e.g., as determined from a patient's barcode, RFID, or other patient identification). Additionally or alternatively, the monitoring client 1, the infusion pump 7, the syringe pump 126, the microinfusion pump 130, or the pill dispenser 128 may interrogate the electronic medical records database 19 or 19′ and/or the pharmacy 22 to verify the prescription or download the prescription, e.g., using a barcode serial number on the infusion pump 7, the syringe pump 126, the microinfusion pump 130, the pill dispenser 128, or the IV bag 170.
Optionally, the monitoring client 1, the other monitoring client 4, and/or the remote communicator 11 may be used to send commands or requests to the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 such as for example, a bolus amount, an infusion flow rate, a total fluid for delivery, a start time for drug delivery, a stop time for drug delivery or a flow-delivery-rate profile to the infusion pump 7, the syringe pump 126 and/or the microinfusion pump 130. In some embodiments, one or more of the monitoring clients 1, 4, 11 may be used to send commands or requests to the pill dispenser 7, such as, for example, a pill dispense command to dispense a pill, a pill-type, a pill dispensing schedule, and/or a max pill-dispensing criteria. The max pill-dispensing criteria may be a maximum amount of a medication that may be delivered within a predetermined interval of time; for example, certain medications are taken as needed (i.e., pro re nata); however, the medication may not be safe if taken in excess and the max pill-dispensing criteria may prevent the medication from being taken at unsafe levels by the patient, e.g., a predetermined amount during a predetermined interval of time.
Optionally, the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 may also communicate data back to the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11 for: determining if an alarm or alert should be issued or sent; determining if the treatment or condition is safe for the patient; determining if the system 100 is operating properly or within predetermined bounds; and/or for displaying the data on a display of the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11. For example, optionally, the infusion pump 7, the syringe pump 126, and/or the microinfusion pump 130 may communicate (where applicable): upstream pressure; changes in upstream pressure; pressure downstream to the patient 2; changes in pressure downstream to the patient 2; the presence or absence of air within an infusion line; an actual bolus amount delivered; an actual infusion flow rate; an actual total fluid delivered; an actual start time for drug delivery; an actual stop time for drug delivery; or an actual flow-delivery-rate profile to one or more of the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11. In another embodiment, the pill dispenser 128 may optionally communicate data back to the monitoring client 1, the other monitoring client 4, and/or the remote communicator 11, such as, for example, an actual pill dispensed, an actual pill-type dispensed, an actual pill dispensing schedule as dispensed, or whether or not a max pill-dispensing criteria was exceeded.
The data received from the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 may be analyzed for any predefined conditions to issue an alarm and/or an alert. For example, one or more of the monitoring clients 1, 4, 11 may use an increase in pressure downstream of the infusion pump 7, the syringe pump 126 and/or the microinfusion pump 130 to be an indication of one of: excessive clotting, infiltration, occlusion or kinking of the tubing to the patient; or occlusion caused downstream by material, e.g., such as contamination found within the IV bag 170. In response to the sudden increase in downstream pressure, one or more of the monitoring clients 1, 4, 11 may visually or audibly alarm or alert a user. These alarms and/or alerts may also inform a nurse to take other appropriate actions, e.g., a suggestion to change a needle in response to an occlusion (e.g., one caused by clotting) when the pressure downstream to the patient rises above a predetermined threshold, or a suggestion to check for a kink in the line when the pressure downstream to the patient rises above a predetermined threshold
Additionally or alternatively, a sudden decrease in pressure downstream to the patient 2 may be an indication that the tubing has become detached from the needle and/or the needle is now out of the patient; and, in response, one or more of the monitoring clients 1, 4, 11 may visually or audibly alarm or alert a user to reattach the tubing to the needle or insert a new needle for continued infusion. The alarm may also indicate that action needs to be taken quickly, e.g., because the patient may be bleeding such as when the tubing becomes detached from the needle and the patient is bleeding through the unattached needle coupler.
In some embodiments, additionally or alternatively, the pressure upstream to one or more infusion pumps 7 may be monitored for any upstream occlusions. For example, contamination with the IV bag 170 may clog the tubing upstream of the infusion pump 7. During each time the infusion pump 7 attempts to pump fluid from the IV bag 170, the pressure upstream to the infusion pump 7 may drop lower than would occur when there is no occlusion upstream. Therefore, one or more of the monitoring clients 1, 4, 11 may issue an alarm or alert when the upstream pressure drops below a predetermined threshold and suggest or require a caregiver to alleviate the occlusion, e.g., by changing tubing or a IV bag 170.
One or more of the monitoring clients 1, 4, 11 may, optionally, send a command to one or more of the infusion pump 7, the syringe pump 126, and/or the microinfusion pump 130 to stop delivery of fluid in response to the sudden increase and/or decrease of pressure downstream to the patient 2.
As shown in
In this example embodiment, a cable 110 is coupled to both of the docks 102, 104 to provide a communications link therebetween. The cable 110 may be permanently attached to or is attachable to one or both of the docks 102, 104. Additionally or alternatively, the cable 110 may include one or more connectors (not explicitly shown) for plugging the cable into one or both of the docks 102, 104.
In some embodiments, the docks 102, 104 can communicate with each other using one or more wires and/or waveguides within the cable 110. For example, in an embodiment of the present disclosure, the cable 110 includes a fiber-optic waveguide to provide an optical communications link between the docks 102, 104. In other embodiments, and as will be appreciated in light of this disclosure, cable 110 can be replaced with one or more wireless communication links (e.g., Bluetooth, etc), if so desired. Still other embodiments may employ a combination of wired and wireless communication channels between docks 102, 104. Any number of suitable wired connection types can be used in various embodiments.
In some embodiments, the communications link between the docks 102, 104 may use any know communications links, such as serial communications, parallel communications, synchronous communications, asynchronous communications, packet-based communications, virtual-circuit based communications, and the like. Additionally or alternatively, in some embodiments, the communications link established between the docks 102, 104 may utilize a wireless connection, a wired connection, a connectionless protocol, e.g., User Datagram Protocol (“UDP”), or a connection-based protocol, e.g., Transmission Control Protocol (“TCP”). For example, the communications between the docks 102, 104 may be based upon one or more of a Universal Serial Bus standard, SATA, eSATA, firewire, an Ethernet standard, Fibre Channel, Bluetooth, Bluetooth Low Energy, WiFi, any physical layer technology, any OSI-layer technology, and the like.
When the monitoring client 1 is docked to the monitoring-client dock 102, the monitoring client 1 has access to the communications between the docks 102, 104. For example, in some embodiments of the present disclosure, the monitoring client 1 can communicate with electronic circuitry within the device dock 104, e.g., a memory, via the communications link provided by the cable 110. Additionally or alternatively, the monitoring client 1 can communicate with any device docked to the device dock 104 through the communications link provided by the cable 110 and/or one or more wireless communication links (described in more detail below).
With further reference to the example embodiment shown in
As shown in
In some embodiments, the monitoring client 1 may electrically determine if one or more electrical contacts of one or more connectors are in electrical engagement with the monitoring-client dock 102 to determine if the cable 110 is available as a communications link, e.g., by measuring a voltage or an impedance between two electrical contacts of a connector of the monitoring client 1 used for docking to the monitoring-client dock 102 and for providing electrical communication between the monitoring-client dock 102 and the monitoring client 1. Also, the monitoring client 1 may determine the cable 110 is unavailable if the monitoring client 1 determines it is not electrically coupled to the cable 110. Additionally or alternatively, in some embodiments, a magnet in the dock 102 engages a Hall-Effect sensor in the monitoring client 1, which the monitoring client 1 uses, in turn, to determine if it is docked such that the monitoring client 1 assumes the cable 110 is unavailable as a communications link when the monitoring client 1 is undocked. Additionally or alternatively, circuitry within the monitoring-client dock 102 may signal the monitoring client 1 when the cable is unavailable as a communications link. In some embodiments, the monitoring client 1 may periodically “ping” the device dock 104 via the cable 110; if the monitoring client does not receive a response from the device dock 104 within a predetermined amount of time, the monitoring client 1 will assume the cable 110 is unavailable as a communications link.
In the event the monitoring client 1 determines the cable 110 is unavailable as a communications link, the monitoring client 1 may issue an alarm or alert using a speaker and/or a vibration motor, an alarm or alert signal may be sent to the remote communicator 11 to alarm or alert the remote communicator using a speaker and/or a vibration motor, and/or the monitoring client 1 may attempt to communicate with the patient-care devices via other communications links. The term “alert” as used herein is intended to include “soft” alerts, such as, for example, an alert that is not brought to a person's attention until after a predetermined amount of time has passed and the cause of the alert remains.
In some embodiments of the present disclosure, the monitoring-client dock 102 includes one or more wires or waveguides from the monitoring client 1 to the cable 110 using minimal or no circuitry. For example, in some embodiments of the present disclosure, the monitoring-client dock 102 is a cradle which provides direct electrical coupling from the monitoring client 1 to the cable 110. Additionally or alternatively, in some embodiments of the present disclosure, the device dock 104 includes one or more wires or waveguides to facilitate communications among various docked devices and/or the monitoring client 1 via the monitoring-client dock 102 using minimal or no circuitry. The device dock 104, in some embodiments, may be a cradle.
In an embodiment of the present disclosure, each monitoring client 1 is assigned to a specific patient 2 and may be a desk-based, portable, or hand-held and may have a display and user input capability. The monitoring client 1 may be portable and can facilitate efficient data viewing and data entry; the monitoring client 1 may be a notebook PC, a netbook PC, a tablet PC, a “smart-phone,” with or without a touchscreen. Additionally or alternatively, in some embodiments, the monitoring client 1 and/or the remote communicator 11 may be docked or coupled to a cable that is connected to a much larger display thereby turning the much larger display (e.g., a 24-inch display) into the display of the monitoring client 1 and/or the remote communicator 11; the much larger display may having input capabilities, such as touchscreen capabilities, stylus-input capabilities, keyboard input capabilities, remote-control input capabilities, and the like that are communicated to the monitoring client 1 and/or the remote communicator 11. For example, the viewing of X-ray or patient imaging files may be facilitated by docking the monitoring client 1 and/or the remote communicator 11 to a viewing-dock coupled to a larger display such that the care giver can see the patient imaging file using the larger display. The viewing-dock may also charge the monitoring client and/or remote communicator 11.
The monitoring client 1 may run a Linux-based operating system, an Android-based operating system, a Blackberry-based operating system, a tablet-based operating system, iOS, an iPad OS, an iPhone OS, and the like. The designation of a particular monitoring client 1 to a particular patient 2 may be made using any of a number of methods, including (but not limited to) a unique patient identifier encoded on a bar code 114 or an RFID tag 116 embedded in a wrist band 118, for example. The device dock 104 includes a scanner 120 to determine the unique patient identifier of the bar code 114 or RFID tag 116. The scanner 120 may be a laser barcode scanner, a CCD-based barcode scanner, a near field communicator or interrogator, an RFID reader, and the like. In other embodiments, note that the unique patient identifier can be based on biometric data of the patient. In one such example case, biometric capability (e.g., facial and/or voice recognition, retina scan, blood type monitor, finger print scan, etc) can be embedded in or otherwise associated with the monitoring client 1. The device dock 104 can communicate the unique patient identifier to the monitoring-client dock 102, the monitoring client 1, the monitoring server 3, the remote communicator 11, other monitoring clients 4, another server, or an electronic computing apparatus to facilitate the treatment of the patient 2.
The monitoring client 1 may include one or more of microprocessors, microcontrollers, logic devices, digital circuitry, analog circuitry, and the like to communicate (e.g., send or receive) information relevant to the patient's 9 care, condition, disease, or treatment. For example, the monitoring client 1 may send or receive patient-care parameters, such as patient-condition parameters and/or patient-treatment parameters. Some exemplary patient-condition parameters are measurements of blood pressure, body temperature, heart rate, a pulse oxymeter, CO2 levels, blood oxygen levels, patient alertness, patient consciousness, patient responsiveness, and the like. Some exemplarily patient-treatment parameters include a drug to be administrator, a flow rate of a drug or liquid, a drug administration schedule, or other bedside treatment parameter.
In some embodiments, for example, the monitoring client 1 may be physically associated with, permanently attached to, is attachable to, is detachable from, or is attachably detachable from the infusion pump 7. This can be accomplished by a docking interface between the two devices, e.g., the monitoring-client dock 102 and the device dock 104. In one such embodiment, the monitoring client 1 communicates with the pump 7 (or other patient-care device) in a number of ways, including, for example, through electrical contacts in the docks 102, 104, by means of an electrical connector, or wirelessly by means of transceivers on each device using a respective antenna 112, 122A. Additionally or alternatively, the infusion pump may include preprogrammed treatment data indicating a particular treatment for a particular patient that is uploaded to the monitoring client 1 when the infusion pump 7 becomes in operative communication with the monitoring client 1.
The monitoring client 1 may also communicate with one or more databases in the facility 8, with databases external to the facility 9, 10, and/or with health care providers using portable communicators 11 (including, for example, physicians, nurses, and pharmacists). This can be accomplished by a wired connection to a facility server 8 through a connector in the patient's room (such as, for example, a Category 5 local area network connector, USB, wired Ethernet, and the like), or wirelessly 12 (such as, for example, WiFi, 3G, 4G, EVDO, WiMax, and the like). In one embodiment, access to intra- and extra-facility databases is mediated 13 through the monitoring server 3 (e.g., using middleware), which can then centralize the software and application programming interfaces to communicate with databases having disparate organization, formatting, and communications protocols. Thus, in an embodiment of the present disclosure, any software updates may be largely limited to the monitoring server 3, reducing the maintenance requirements on the individual monitoring clients 1, 4, 11. Optionally, a monitoring client 1 can communicate with patient-treatment devices, such as an infusion pump 7, to receive information about the progress of treatment (such as operating parameters) and to provide operational instructions to the patient-treatment device. In another embodiment, the monitoring client 1 may also communicate with patient-care devices for diagnostic or monitoring purposes to receive patient-condition parameters (such as, for example, an electrocardiographic (“ECG”) monitor 14, a blood pressure (“BP”) monitor 15, a pulse oximeter or CO2 capnometer 16, or other devices such as temperature monitors, etc.) to receive readout information from the devices and potentially to instruct the devices 14, 15, 16, 17 to take a reading when desired by a provider or by an algorithm.
In an embodiment of the present disclosure, the facility services 8 and/or the drug adverse event network 9 may also include a Drug Error Reduction System (“DERS”). The DERS system may include a first set of predetermined criteria to trigger soft alarms and/or a second set of predetermined criteria to trigger hard alarms. Soft alarms may be overridden (e.g., turned off) by a caregiver using a user interface of an infusion pump 7 and/or a monitoring client 1 (and may be only an audible and/or vibratory alarm) while hard alarms cause the treatment to cease until the source of the hard alarm is removed.
In yet an additional embodiment of the present disclosure, the DERS system may include a first set of predetermined criteria defining soft limits and/or a second set of predetermined criteria defining hard limits. The hard and soft limits define treatment limits, such as drug dosage limits based upon size, weight, age, other patient parameters, or other criteria. Soft limits may be overridden by a caregiver using a user interface of the infusion pump 7 and/or the monitoring client 1 to start treatment despite that the treatment is outside of the first set of predetermined criteria while the hard limits prevent the treatment from starting until the settings are changed to confirm to the second set of predetermined criteria defining the hard limits.
As can further be seen in the example embodiments of
Each of the communication modules 124A-124K optionally includes one or more transceivers for optionally communicating over one or more wireless links to each other, to the device dock 104, to the monitoring-client dock 102, to the monitoring client 1, to the remote communicator 11, to the monitoring server 3, over the local area network and/or wide area network (e.g., the Internet), to a hub 802 (see
In other embodiments, each patient-care device may include no modules or more than two modules (e.g., communication modules). For example, each module may have a specific function, e.g., WiFi, and a user can select a plurality of modules each having a specific function and couple them together. The group of modules may then be applied to the patient-care device, e.g., an infusion pump. Consider yet another example: each module may have a primary processor, a backup processor, and functional circuitry, all in operative communication with each other. The functional circuitry may be a wireless transceiver, a battery, an interface to a touchscreen or display (the display may be attached to the housing), a wire connection, Bluetooth, Bluetooth Low Energy, WiFi, 3G, 4G, a co-processor, a control system (e.g., to control an infusion pump), a medication with fluid measurement circuitry, and the like. The selected modules may be connected together, e.g., in a daisy chain, and thereafter connected to an infusion pump. The selected modules, in this example, may be in operative communication with each other to coordinate their action and/or function, e.g., via a CAN bus, wired connection, wirelessly, and/or the like.
The modules may each include a speaker and a microphone. When several modules are connected to together, the modules may coordinate their operation such that one module audibly signals a speaker while another module uses a microphone to determine if the speaker is functioning properly. Several modules may each use their speaker on a different frequency such that any one of the modules may sense the sound via its microphone and demodulate the different frequencies to test several of the speakers simultaneously. The test may be requested by a first module to a second module, and the second module may send the results from the test to the first module.
Continuing to refer to
As will be appreciated in light of this disclosure, the communication modules 124A-124K can be operatively coupled to a variety of patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 148. For example and with further reference to
Additionally or alternatively, in some embodiments, the communication module 124D is docked in the device dock 104 and is operatively coupled to the device dock 104 via, for example, a bus or backplane for communicating with any device attached to the device dock 104, as well as for communicating with electronic circuitry within the device dock 104, electronic circuitry within the monitoring-client dock 102, and/or the monitoring client 1. Optionally, the communication module 124D can provide communications for and/or power to any device docked within the device dock 104, e.g., the infusion pump 7, the syringe pump 126, the pill dispenser 128, or a microinfusion pump 130. Note the functionality of communication module 124D can also be integrated into the circuitry of the device dock 104 itself.
Additionally or alternatively, in some embodiments, it is optional for the communication modules 124 to each be configured to provide a sufficient power supply for their respective device 7, 14, 15, 16, 17, 35, 126, 128, 148 which may be supplemented by one or more wired power sources, for example, a power source accessible through the bus or backplane within the device dock 104. As previously mentioned, in some embodiments of the present disclosure, the communication module 124D provides sufficient power to the devices 7, 126, 128, 130, and 133.
As previously mentioned, in some embodiments, the communication modules 124 are each configured with power circuitry (e.g., a voltage converter, regulator circuitry, rectification and filtering circuitry, a buck circuit, a boost circuit, a buck-boost circuit, a switched-mode power supply, etc.) that provides sufficient power to the corresponding devices 7, 126, 128, and 130. In some such cases, this power circuitry may be configurable so as to allow for provisioning of various power supply characteristics (e.g., voltage level, maximum load/current requirements, and A/C frequency) associated with the different and diverse patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 148. Any number of power provisioning and management schemes will be apparent in light of this disclosure.
Optionally, in other embodiments of the present disclosure, a power module 132 having one or more battery cells, e.g., lithium-ion battery cells, is attached to the device dock 104 to provide sufficient power to the devices 7, 126, 128, 130, 133 for the full treatment duration. Additionally or alternatively, the power module 132 may be plugged into an outlet in the patient's room (generally depicted in
The example system 100 may optionally include a dongle 133. The dongle 133 is docked in the device dock 104 in
In some embodiments, the dongle 133 may communicate patient-care parameters, e.g., patient-treatment parameters or patient-condition parameters, from one or more patient-care devices and retransmit them to the monitoring client 1, the hub 802 of
Optionally, the system 100 may also include a wearable system monitor 131 for monitoring the operation of various devices, docks, monitoring clients, and/or servers. A monitoring client 1, a remote communicator 11, and/or a hub 802 of
The communications from the wearable system monitor 131 may include one or more interrogation signals to determine if the device being interrogated is functioning properly, is functioning within predetermined operating parameters, and/or is otherwise in a condition or state that is undesirable. The system monitor 131 can communicate the detected condition or error to one or more devices, such as to the monitoring server 3, the monitoring client 1 or the hub 802 of
The system monitor 131 can implement its functionality in various ways, including, for example: (1) anticipating a response to an interrogation within a predetermined amount of time; (2) incrementing a counter within the device being interrogated, and requesting the value of the counter from the device after being incremented; (3) a challenge-response interrogation; and/or (4) other system monitoring technique or method.
As previously mentioned, in some embodiments, the system monitor 131 anticipates a response to an interrogation within a predetermined amount of time after interrogating a patient-care device paired to the system monitor 131. For example, the system monitor 131 may send a text-string message to the infusion pump 7 of “system monitor interrogation.” In this example, the infusion pump 7 receives the message from the system monitor 131 labeled “system monitor interrogation,” and processes the message using one or more processors therein. When the infusion pump 7 processes the message, a software routine therein executes code that sends a response message back to the system monitor 131; for example, the response message may be a text-string message of “system monitor response” that is sent to the system monitor 131. In this example, the system monitor 131 may expect to receive the response message within a predetermined amount of time, such as 2 seconds, which if the system monitor 131 does not receive the response message within 2 seconds, the system monitor 131 alarms and/or sends an alert to other devices (e.g., the system monitor 131 may broadcast an alert or error message, or may cause can alarm or alert, audibly or visually, to be provided to the possessor via the remote communicator 11).
As previously mentioned, in some embodiments, the system monitor 131 causes a counter within the device being interrogated to increment and requests the value of the counter from the device after being incremented. For example, the system monitor 131 may send a request to a patient-care device, e.g., infusion pump 7, by sending it a message, such as “increment counter,” to the device. The device's processor receives the “increment counter” message and reads a value from a memory location of the device, increments the value found in the memory location, and stores the new value in the same memory location by overwriting the previous value. Thereafter, in this example, the processor reads the new value from the memory location and sends that new value to the system monitor 131, e.g., via a wireless transceiver on the device being interrogated. The system monitor 131, in this example, will expect a certain value from the device being interrogated (this expected value may be stored in a memory of the system monitor, such as, for example, in a table). For example, the system monitor 131 may have stored within its memory that a value of 48 that was previously received from the device, and after requesting the value be updated within the interrogated device, expects to receive a value of 49 from the device.
Also as previously mentioned, a challenge-response interrogation may be used by the system monitor 131. For example, the system monitor 131 may send an encrypted message to a patient-care device. The patient-care device is then tasked to decrypt the message, e.g., using an encryption key, and send the message back to the system monitor 131. The system monitor 131 may expect the unencrypted message to return within a predetermined amount of time. In this example, if the system monitor 131 does not receive the response message within the predetermined amount of time, the system monitor 131 alarms and/or sends an alert to other devices (e.g., the system monitor 131 may broadcast an alert or alarm message and/or transmit them to the monitoring client 1, the monitoring server 3, to the hub 802 of
In an embodiment of the present disclosure, the monitoring client 1 has the ability to communicate and interact directly with a health care provider using a hand-held or portable remote communicator 11 (which can be, for example, a Smartphone, a tablet computer, a PDA, a laptop, or other portable computing device). This may be accomplished wirelessly 12, so that communications can be maintained regardless of the patient's location in the facility, or the provider's location either within or outside the facility. In one aspect, information specific to the patient 2 can be stored locally in the monitoring client 1, so that the patient's health care provider can access the information directly without having to access the monitoring server 3.
In some embodiments, optionally, by incorporating appropriate safety and security clearances, changes to the settings or flow parameters of a connected infusion pump 7 or patient-monitoring device 14-17, 35, 126, 128, 130, 148 can be accomplished directly between a provider's monitoring client 11 and the monitoring client 1 (via wired or wireless communications), with selected changes also being communicated to the monitoring server 3, and thence optionally to other appropriate locations, such as the nursing station 5 and/or the pharmacy 6. Furthermore, any new order pertaining to the patient 2 may be entered in the ordering provider's remote communicator 11 (e.g., Smartphone) and transmitted to the monitoring client 1, which in turn can then notify the care giver (e.g. a nurse, nurse practitioner, doctor, physician, or other health-care professional) via the care giver's own portable communicator 11. Additionally or alternatively, in some embodiments, the new order may also be communicated to the infusion pump 7 or patient-monitoring device 14-17, 35, 126, 128, 130, 148 such that the control system therein or coupled thereto can change its operation, e.g., setpoint, in response to the new order. In some embodiments, any information acquired and stored in the monitoring client 1 is periodically uploaded to the monitoring server 3 and stored in a patient-specific database. Thus, if a patient's monitoring client 1 is taken out of service, a new device can be assigned to the patient 2 and quickly re-populated with the patient's current information from the monitoring server 3. Orders, medications, progress notes, monitoring data, treatment data, patient-treatment parameters, patient-monitoring parameters, and/or operating parameters from the patient's attached devices may also be uploaded from the monitoring client 1 to the patient's EHRs 19, any applicable remote communicators 11, the hub 802 of
In some embodiments, the monitoring server 3 may comprise a computer that can communicate with and provide some elements of control for a number of monitoring clients 1, 4, 11 in the facility 8. The monitoring server 3 may provide the monitoring clients 1, 4, 11 with data extracted from a number of databases both within 8 and outside 9 of the facility. In an embodiment of the present disclosure, the monitoring server 3 can interrogate the facility's EHR system 19 for targeted information pertaining to a patient 2, and then populate that patient's monitoring client 1 with a pre-defined set of information (such as, for example, the patient's age, height, weight, categories of diagnoses, current medications and medication categories, medication allergies and sensitivities, etc.). In accordance with one such example, the monitoring server 3 may establish a communication link to the EHR 19, laboratory 20, radiology 21, pharmacy 22, and/or other systems (such as, e.g., cardiology 23 or scheduling database 24) in the facility when, for example, a monitoring client 1 has been assigned to a patient 2. With a unique patient identifier, the monitoring server 3 can obtain electronic access (permission) to receive and send patient-specific data from and to these systems. A predetermined (but selectable) subset of the data may be downloadable into the monitoring client 1's memory (not explicitly shown in
The information thus acquired can then serve as a key database against which new orders can be analyzed. Orders entered into a monitoring client 1 can be checked for compatibility with the patient-specific information obtained by the monitoring server 3. Optionally, for safety redundancy, orders entered remotely from a communicator 11 can be intercepted by the monitoring server 3 and similarly can be checked. The monitoring server 3 may also obtain information from medication databases residing in the facility's pharmacy 22 or externally 9 to determine whether a new patient order may generate an incompatibility with a patient's existing medications, for example. In an embodiment of the present disclosure, the monitoring server 3 may be programmed to access publicly available internet sites 25 to determine whether new information pertaining to the patient's ordered medication should be downloaded and transmitted 13 in an alert or alarm to the patient's health care provider(s). The monitoring server 3 may also route information between remote portable communicators 11 and a patient's monitoring client 1.
In an embodiment of the present disclosure, the patient's physician, nurse or pharmacist may have access to the patient's monitoring client 1 to relay or receive new orders (such as medication orders, for example) pertaining to the patient 2. The monitoring client 1 or server 3 may then log the new order and relay the request to the pharmacist 6, and the patient's nurse via the nurse's portable communicator 11 and/or via a fixed terminal at the nursing station 5. A ‘smart phone’ having a customized communications application with the monitoring client 1 (such as, e.g., a Google's Nexus One phone, Apple's iPhone, or RIM's Blackberry OS, among others) may serve as a convenient portable communicator 11 for providers who are not at a fixed location (such as at an office or remote nursing station). A tablet PC, netbook, or laptop computer may also serve as a convenient portable communicator 11 for both portable and fixed locations. A PC may act as a convenient communication device 11 for fixed or desktop locations. If a provider is located in the patient's room, he or she may enter or receive information pertaining to the patient 2 using a direct input through a keyboard or touchscreen on the monitoring client 1.
A monitoring client 1 can receive, process, and transmit information about a specific patient 2 to which it has been assigned or designated. The monitoring client 1 can most conveniently be attachable or dockable to the monitoring-client dock 102 to communicate with the infusion pump 7, or any other device to which the patient 2 may be connected or associated. The monitoring client 1 can be a hand-held device about the size of a wireless phone or tablet-style netbook, for example. Conveniently, it may have a touchscreen interface for use by the patient's provider. It may also be capable of providing output to a larger stationary display in the patient's room or at a nursing station 5 or other convenient location, either through a wired or wireless connection. Each monitoring client 1 may communicate with a central monitoring server 3, through which it can access patient data from the facility's EHR database 19, a laboratory database 20, a radiology database 21, a pharmacy database 22, or other databases in various other facility departments. In some cases, the monitoring client 1 can upload information it receives from patient monitoring devices 14-17 or from provider inputs to the patient's EHR 19 via the Monitoring Server 3. Monitoring clients 1,4 may also receive information from databases outside of the facility through a monitoring server 3 having an internet connection 25. Various external databases 9 may thus be accessible, including various drug information databases and alert networks dealing with adverse medication-related events.
The monitoring server 3 could be arranged, for example, to manage various levels of external database information helpful in keeping the monitoring client 1 contents as up-to-date as possible. This can be accomplished, for example, by comparing safety and drug information related to the patient as it becomes available, and prioritizing for updates/downloads on a data transfer schedule. The monitoring clients 1,4 may also communicate either directly or through the monitoring server 3 with portable communicators 11 used by health care providers such as nurses, physicians and pharmacists. In some cases, these devices can have wired connections to the monitoring server 3 (if used, for example, in fixed locations such as hospital pharmacies or nursing stations). In other cases, a portable communicator 11 may communicate with the monitoring server 3 through secure internet connections (e.g., a VPN-based internet connections, UPN, Https, a private key mechanism, etc.) using a computer and a wired or wireless (e.g., Bluetooth or WiFi 802.11) connection 13 with the device 11. Alternatively, a hand-held remote communicator 11 (such as a smart-phone or tablet netbook) may communicate directly 12 with the facility's monitoring client 1 via a cellular telephone network and/or the facility may include a private cell network that may include a WiFi network (e.g., 2.4 GHz to 2.4835 GHz unlicensed ISM band, for example).
In some embodiments, the communication link between the monitoring clients 1,4 and the monitoring server 3 may exist via an Ethernet network if widely available in the facility, or via wireless transmission using one of a number of standards, linking all the patient-specific monitoring clients 1,4 with the central monitoring server 3. The server 3 may then serve as a relay for communications with other facility servers 8, with the web-based servers 25, and with inside and outside portable communicators 11 carried by medical care providers. In some embodiments, a wireless network provides the additional functionality of being able to communicate with the monitoring server 3 no matter where in the facility the patient 2 may be.
One method of blanketing an entire facility with wireless coverage involves having the facility obtain a license for a private cell-phone network. It may obtain or lease one or more micro-cellular frequencies to provide for a local communications network throughout the facility. This arrangement can preserve communications when patients and their monitoring clients 1,4 are moved from one location to another within the facility, maintaining communications with a monitoring server 3, various in-hospital and out-of-hospital databases 8, 25, and users at fixed stations (e.g., in some embodiments, the nursing station 5 and the pharmacy 6) or with a monitoring client 11 (e.g., mobile smart-phone, laptop or tablet-type devices) either inside or outside the hospital. In some embodiments, this type of system provides additional security via a licensed cellular communications infrastructure. In addition, in some embodiments, an active wireless system can monitor the intensity of use in an area and direct additional channel frequencies to that area. However, in some embodiments, the bandwidth capacity of the network may not allow for efficient transmission of large data files, such as those containing radiology images, for example. Such bandwidth-heavy data files can be communicated more efficiently via wired connections.
Alternatively or additionally, a hospital may implement an internet- or intranet-based communications system, in which an 802.11 WiFi-type protocol is used for wireless communications between individual monitoring clients 1,4 and the monitoring server 3. To ensure adequate signal reception throughout the facility, a broadband antenna may be mounted on the roof of the building to collect cell phone signals from local wireless phone companies. A fiber-optic or cable network may then distribute the signals throughout the facility. Additionally or alternatively, the monitoring server 3 may use the private cell-phone network mentioned above. Such systems typically allow for provisioning of secure communications, and are capable of efficiently communicating large files, such as, for example, radiology images stored in the radiology database 21. Home or office-based users may be able to connect to the hospital server through, for example, VPN or other secure access using wired or fiber-optic cable, or a DSL phone line. Data encryption may be used to provide patient data security. In some applications it may be advantageous to implement an asymmetric bandwidth communications network in order to optimize infrastructure capabilities. An example of this would be using licensed cellular frequencies in the “upstream” direction from the monitoring client 1 to the monitoring server 3 and the unlicensed 802.11 WiFi frequencies in the “downstream” direction from the monitoring server 3 to the monitoring client 1. In this example, the upstream bandwidth and data rate requirements are relatively small compared to the downstream requirements. In low priority upstream transmissions, the monitoring client 1 may allow data to be sent over a more distributed and cost-efficient network, such as, for example, a ZigBee network, a Bluetooth network, a mesh network, or the like.
As previously mentioned, communications between various monitoring devices, such as patient-care devices 14, 15, 16, 17, 35, and the monitoring client 1 may be achieved in a cost effective manner using, for example, a ZigBee wireless mesh network and/or a Bluetooth network. Exemplary monitoring devices include ECG monitors 14, blood pressure monitors 15, pulse oximeters/capnometers 16, thermometers, and weight scales, among others. A common characteristic of most of these devices is that they provide periodic readouts of a single or small number of parameters. An intra-hospital device communications system such as the wireless mesh network provides for low-power digital radio connectivity among devices, and may employ a widely available, license-free frequency band (e.g., 2.4 GHz in some jurisdictions). High-level communications protocols may be employed to ensure data fidelity and security, such as, for example, TCP, UDP, and the like. For example, symmetrical encryption keys may be used to secure communications between the monitoring client and patient-care devices, such as those generated for the encryption algorithms of Twofish, Serpent, AES (Rijndael), Blowfish, CAST5, RC4, 3DES, IDEA, and the like. Additionally or alternatively, various data integrity techniques may be used, for example, CRC, odd parity-bit checking, or even parity-bit checking, and the like.
Mesh networks are highly scalable, allowing many devices to be used on a single self-forming, self-healing mesh network. Devices connected to the network may communicate with one another and serve as repeaters to transfer data. Mesh network may be relatively low cost, scalable and mobile for the patient being monitored. In some embodiments, the wireless range for devices linked to the wireless mesh network can approach 70 meters from each node of the system inside a facility. A similar network may be used in providing a wireless link within the facility between portable communicators 11 carried by health care providers and their assigned patients through the patients' monitoring clients 1,4.
In many cases, the information being transmitted to the monitoring client 1 may include a single parameter value (such as, for example, blood pressure) and a time stamp. The monitoring client 1 can be programmed to determine whether the value is outside a predetermined range, record the value in the patient's EHR 19, and notify the appropriate provider via their monitoring client 11. Furthermore, the network may enable bidirectional communications, and may allow the monitoring client 1 to query the patient-monitoring device (e.g., BP monitor 15), instructing it to take an unscheduled reading. This can be useful, for example, when an abnormal reading is received, and its authenticity needs to be verified. The monitoring client 1 may be programmed to request a repeat reading to verify the abnormal reading. In a further embodiment, the monitoring client 1 may be programmed to interrupt or adjust the infusion pump 7 flow rate, operating parameter, and/or treatment parameter depending on the value of the reading received from a monitoring device 14-17. For example, if the BP monitor 15 indicates a blood pressure below a predetermined acceptable range, the monitoring client 1 may be programmed to instruct the infusion pump 7 to stop the infusion, and it can transmit an urgent notification 12 to the health care provider(s)' monitoring clients 11. In another embodiment, if the infusion pump 7 is capable of determining the volume of fluid being delivered to the patient 2 (e.g., the flow rate or the cumulative amount of fluid pumped during an interval), a processor in the monitoring client 1 may track the cumulative volume delivered and estimate the amount of fluid remaining in the medication bag 170. (Alternatively, a processor in the monitoring client 1 or infusion pump 7 may calculate the volume delivered from the infusion rate and elapsed time of infusion).
Once the estimated residual volume reaches a predetermined amount, the monitoring client 1 may signal the infusion pump 7 to reduce its flow rate to keep the patient's IV access 35 from running dry. For example, the monitoring client 1 may determine that a nurse is scheduled to return at a specific time to change the bag, and rather than alarming and/or sending an alarm that the IV fluid will run out prior to the nurse's scheduled return, the monitoring client 1 may signal the infusion pump 7 to slow the infusion rate such that the IV bag will run out when the nurse arrives or after a predetermined amount of time from the nurse's scheduled return time. It may also send a notification to the nurse's monitoring client 11, recommending replenishment of the IV bag 17.
In some embodiments, the operation of a patient-care device progresses is indicated by an outer border on a display of the monitoring client 1 to show the status and/or progress of the patient-care device. For example, an outer border will be display on the monitoring client 1 such that a percentage of the border that lights up (e.g., starts to form a fully filled outer periphery as the border fills in) to indicate the progress of a treatment being performed by a patient-care device, such as the infusion pump 7. The border may be transmitted in image format (e.g., JPEG, BMP, etc.) to the monitoring 1 from the infusion pump 7 and/or as a percentage completed to the monitoring client 1, in which case the monitoring client 1 generates the border.
In some embodiments, a GPS and/or a ranging module (e.g., ultrasonic ranging module using time-of-flight estimations) may be installed on the infusion pump 7, the monitoring client 1, a caregiver, and/or a patient. Predetermined settings may require that a predetermined group of the infusion pump 7, the monitoring client 1, the hub 802 of
In some embodiments, a patient-care device 7, 170, 126, 128, 130, 14, 15, 16, 17, 124, or 148, a dock 102 or 104, a monitoring client 1, the hub 802 of
In some embodiments, the AC cable of
In some embodiments, the infusion pump 7 includes status LED lights indicating one or more of: safety-checks have passed; the pump is flowing; there is an occlusion; and/or the pump is being disconnected). A user can use the monitoring client 1 to read a bar code on the IV bag 170 (e.g., using the camera 144 or the camera 136, and/or the scanner 120) at which time an LED over a plug may flash to indicate to the user that the tube connected to the IV bag 170 should be inserted therein.

Additionally or alternatively, although particular patient-care devices 7, 14, 15, 16, 17, 126, 128, 130, 148 are shown, other combinations, subsets, multiple ones of a particular patient-care device, or combinations thereof may be used. For example, in some embodiments, only an infusion pump 7 is used of the patient-care devices, and, in this specific example, the other patient-care devices 14, 15, 16, 17, 126, 128, 130, 148 may be disabled, may not be present or available for system use, may be turned off, or may not be part of system 100 of
In some embodiments, the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, and/or 148, the monitoring client 1, the remote communicator 11, and docks 102 and/or 104 may include a secure data class, e.g., via an API.
Any function described with reference to
Act 152 determines if the monitoring-client dock is available as a communications link between the monitoring client and the monitoring-client dock through a dock connector. If the communications link of act 152 is available, the method 150 continues to act 154, otherwise the method 150 continues to act 156.
Act 156 determines if the monitoring-client dock is available as a communications link between the monitoring-client and the monitoring-client dock through a wireless link. If the link of act 156 is available, the method 150 continues to act 154, otherwise, the method 150 continues to act 158.
Act 154 determines if the monitoring-client dock is available as a communications link between the monitoring-client dock and a device dock using a cable. If the communications link of act 154 is available, the method 150 continues to act 160, otherwise, the method 150 continues to the act 158. The act 160 determines if the device dock is available as a communications link between the device dock and the patient-care device, e.g., through a wireless or wired communications link. If the communications link of act 160 is available, the method 150 continues to the act 166, otherwise, the method 150 continues to the act 162. The act 162 determines if the patient-care device is available as a communications link between the monitoring-client and a patient-care device dock through a direct wireless link. If the communications link of act 162 is available, the method continues to act 166, otherwise, the method 150 continues to act 164.
Act 158 determines if the device dock is available as a communications link between the monitoring client and the device dock through a wireless link. If the communications link of act 158 is not available, the method 150 continues to act 162, otherwise, the method 150 continues to act 160.
Act 166 attempts a handshake between the monitoring client and the patient-care device using the available communications link. In alternative embodiments, no handshaking is used; for example, not all protocols use handshaking between communication endpoints. Decision act 168 determines if the handshake of act 166 was successful. If the decision act 168 determines the handshake of act 166 was unsuccessful, then act 164 determines that communication with the patient device is unavailable and/or method 150 attempts to establish communications using other links (not explicitly shown). Otherwise, if decision act 168 determines the handshake of act 166 was successful, act 169 communicates data using a sufficient number of communications links determined to be available by method 150.
Method 150 is an exemplary embodiment of the present disclosure describing a method of maintaining communications between a monitoring client and one or more patient-care devices. In some embodiments, although method 150 includes a schedule of communications links, other schedules may be used, broadcasting, anycast, multicast or unicast may be used, routing algorithms may be used, a distance-vector routing protocol may be used, a link-state routing protocol may be used, an optimized link state routing protocol may be used, a path-vector protocol may be used, static routing with predefined alternative communications paths may be used, and/or adaptive networking may be used. For example, in some embodiments of the present disclosure, weights may be assigned to each communications path and Dijkstra's Algorithm may be used to communicate between the monitoring client 1 and one or more patient-care devices; the weights may be determined in any know way, including as a function of bandwidth, signal quality, bit-error rate, may be linear to the available data throughput or latency, and/or the like.
Referring to the drawings,
Optionally, the monitoring client 1, other monitoring client 4, and/or the remote communicator 11 may be used to send commands or requests to patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 such as for example, a bolus amount, an infusion flow rate, a total fluid for delivery, a start time for drug delivery, a stop time for drug delivery or a flow-delivery-rate profile to the infusion pump 7, the syringe pump 126 and/or the microinfusion pump 130. In some embodiments, one or more of the monitoring clients 1, 4, 11 may be used to send commands or requests to the pill dispenser 128, such as, for example, a pill dispense command to dispense a pill, a pill-type, a pill dispensing schedule, and/or a max pill-dispensing criteria. The max pill-dispensing criteria may be a maximum amount of a medication that may be delivered within a predetermined interval of time; for example, certain medications are taken as needed (i.e., pro re nata), however, the medication may not be safe if taken in excess and the max pill-dispensing criteria may prevent the medication from being taken at unsafe levels by the patient, e.g., a predetermined amount during a predetermined interval of time.
In some embodiments, the remote communicator 11 may be used to initiate two-way audio/visual communications between the remote communicator 11 and the monitoring client 1 (e.g., a video call). Additionally or alternatively, the monitoring client 1 may be used to initiate two-way audio/visual communications between the monitoring client 1 and the monitoring client remote communicator 11.
Optionally, the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 may also communicate data back to the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11 for: determining if an alarm or alert should be issued or sent; determining if the treatment or condition is safe for the patient; determining if the system 300 is operating properly or within predetermined bounds; and/or for displaying the data on a display of the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11. For example, optionally, the infusion pump 7, the syringe pump 126, and/or the microinfusion pump 130 may communicate (where applicable): upstream pressure; changes in upstream pressure; pressure downstream to the patient 2; changes in pressure downstream to the patient 2; the presence or absence of air within an infusion line; an actual bolus amount delivered; an actual infusion flow rate; an actual total fluid delivered; an actual start time for drug delivery; an actual stop time for drug delivery; or an actual flow-delivery-rate profile to one or more of the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11. In another embodiment, the pill dispenser 128 may optionally communicate data back to the monitoring client 1, the other monitoring client 4, and/or the remote communicator 11, such as for example, an actual pill dispensed, an actual pill-type dispensed, an actual pill dispensing schedule as dispensed, or whether or not a max pill-dispensing criteria was exceeded.
The data received from the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 may be analyzed for any predefined conditions to issue an alarm and/or an alert. For example, one or more of the monitoring clients 1, 4, 11 may use an increase in pressure downstream of the infusion pump 7, the syringe pump 126 and/or the microinfusion pump 130 to be an indication of one of: excessive clotting, infiltration, occlusion or kinking of the tubing to the patient; or occlusion by other material within the IV bag 170. In response to the sudden increase in downstream pressure, one or more of the monitoring clients 1, 4, 11 may visually or audibly alarm or alert a user. Additionally or alternatively, a sudden decrease in pressure downstream to the patient 2 may be an indication that the tubing has become detached from the needle and/or the needle is now out of the patient; and, in response, one or more of the monitoring clients 1, 4, 11 may visually or audibly alarm or alert a user. One or more of the monitoring clients 1, 4, 11 may, optionally, send a command to one or more of the infusion pump 7, the syringe pump 126, and/or the microinfusion pump 130 to stop delivery of fluid in response to the sudden increase and/or decrease of pressure downstream to the patient 2.

Act 204 determines if the monitoring-client dock is available as a communications link between the monitoring client and the monitoring-client dock through a dock connector. If the communications link of act 204 is available, the method 202 continues to act 206, otherwise the method 202 continues to act 208. Act 208 determines if the monitoring-client dock is available as a communications link between the monitoring client and the monitoring-client dock through a wireless link. If the communications link of act 208 is available, the method 202 continues to act 206, otherwise, the method 202 continues to act 210.

Act 212 determines if the device dock is available as a communications link between the device dock and the patient-care device. If the communications link of act 212 is available, then method 202 continues to act 216, otherwise, the method 202 continues to act 214.
Act 214 determines if the patient-care device is available as a communications link between the monitoring client and the patient-care device through a direct wireless link. If the communications link of act 214 is available, the method 202 continues to act 216, otherwise, act 218 determines that communication with the patient-care device is unavailable.
Act 216 attempts a handshake between the monitoring client and the patient-care device using the available communications link(s). In alternative embodiments, no handshake is attempted; for example, some communication protocols do not utilize handshaking. Decision act 220 determines if the handshake was successful and communications between the monitoring client and the device have been established. If act 220 determines a communications link has been established, the method 202 communicates data between the monitoring client and the device during act 222 using the available communications link(s). If decision act 220 determines the handshake was not successful, either method 202 determines that communication with the device is unavailable in act 218 or method 202 attempts communications between the monitoring client through untried communication links (not explicitly shown).
Method 202 is an exemplary embodiment of the present disclosure describing a method of maintaining communications between a monitoring client and one or more patient-care devices. In some embodiments, although method 202 includes a schedule of communications links, other schedules may be used, broadcasting, anycast, multicast or unicast may be used, routing algorithms may be used, a distance-vector routing protocol may be used, a link-state routing protocol may be used, an optimized link state routing protocol may be used, a path-vector protocol may be used, static routing with predefined alternative communications paths may be used, and/or adaptive networking may be used. For example, in some embodiments of the present disclosure, weights may be assigned to each communications path and Dijkstra's Algorithm may be used to communicate between the monitoring client 1 and one or more patient-care devices; the weights may be determined in any know way, including as a function of bandwidth, signal quality, bit-error rate, may be linear to the available data throughput or latency, and/or the like.

Optionally, the monitoring client 1, other monitoring client 4, and/or the remote communicator 11 may be used to send commands or requests to patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 such as for example, a bolus amount, an infusion flow rate, a total fluid for delivery, a start time for drug delivery, a stop time for drug delivery or a flow-delivery-rate profile to the infusion pump 7, the syringe pump 126 and/or the microinfusion pump 130. In some embodiments, one or more of the monitoring clients 1, 4, 11 may be used to send commands or requests to the pill dispenser 128, such as, for example, a pill dispense command to dispense a pill, a pill-type, a pill dispensing schedule, and/or a max pill-dispensing criteria. The max pill-dispensing criteria may be a maximum amount of a medication that may be delivered within a predetermined interval of time; for example, certain medications are taken as needed (i.e., pro re nata), however, the medication may not be safe if taken in excess and the max pill-dispensing criteria may prevent the medication from being taken at unsafe levels by the patient, e.g., a predetermined amount during a predetermined interval of time.
Optionally, the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 may also communicate data back to the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11 for: determining if an alarm or alert should be issued or sent; determining if the treatment or condition is safe for the patient; determining if the system 500 is operating properly or within predetermined bounds; and/or for displaying the data on a display of the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11. For example, optionally, the infusion pump 7, the syringe pump 126, and/or the microinfusion pump 130 may communicate (where applicable): upstream pressure; changes in upstream pressure; pressure downstream to the patient 2; changes in pressure downstream to the patient 2; the presence or absence of air within an infusion line; an actual bolus amount delivered; an actual infusion flow rate; an actual total fluid delivered; an actual start time for drug delivery; an actual stop time for drug delivery; or an actual flow-delivery-rate profile to one or more of the monitoring client 1, the other monitoring client 4 and/or the remote communicator 11. In another embodiment, the pill dispenser 128 may optionally communicate data back to the monitoring client 1, the other monitoring client 4, and/or the remote communicator 11, such as for example, an actual pill dispensed, an actual pill-type dispensed, an actual pill dispensing schedule as dispensed, or whether or not a max pill-dispensing criteria was exceeded.
The data received from the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148 may be analyzed for any predefined conditions to issue an alarm and/or an alert. For example, one or more of the monitoring clients 1, 4, 11 may use an increase in pressure downstream of the infusion pump 7, the syringe pump 126 and/or the microinfusion pump 130 to be an indication of one of: excessive clotting, infiltration, occlusion or kinking of the tubing to the patient; or occlusion by other material within the IV bag 170. In response to the sudden increase in downstream pressure, one or more of the monitoring clients 1, 4, 11 may visually or audibly alarm or alert a user. Additionally or alternatively, a sudden decrease in pressure downstream to the patient 2 may be an indication that the tubing has become detached from the needle and/or the needle is now out of the patient; and, in response, one or more of the monitoring clients 1, 4, 11 may visually or audibly alarm or alert a user. One or more of the monitoring clients 1, 4, 11 may, optionally, send a command to one or more of the infusion pump 7, the syringe pump 126, and/or the microinfusion pump 130 to stop delivery of fluid in response to the sudden increase and/or decrease of pressure downstream to the patient 2.

The method determines if the dock is available as a communications link between the monitoring client and the dock through a dock connector during act 306. If the communications link of act 306 is not available, method 304 continues to act 308, otherwise, the method 304 continues to act 310. Act 310 determines if the dock is available as a communications link between the dock and the patient-care device. If the communications link of act 310 is not available, the method 304 continues to act 312, otherwise, the method 304 continues to act 314.
Act 308 determines if the dock is available as a communications link between the monitoring client and the dock through a wireless link. If the communications link of act 308 is available, the method 304 continues to act 310, otherwise, the method 304 continues to act 312.
Act 312 determines if the patient-care device is available as a communications link between the monitoring client and the patient-care device through a direct wireless link. If the communications link of act 312 is unavailable, act 316 determines that communication between the monitoring client and the patient-care device is unavailable.
Act 314 attempts a handshake between the monitoring client and the device using the available communications link(s). In alternative embodiments, no handshaking is utilized; for example, some protocols do not employ handshaking. Decision act 318 determines if the handshake was successful, and if it was successful, method 304 continues to act 320 to communicate data using the available communications link(s). If the decision act 318 determines the handshake was unsuccessful in act 314, act 316 determines that communication with the device is unavailable. In other embodiments, if decision act 318 determines the handshake was unsuccessful in act 314, method 304 attempts to communicate with the patient-care device via untried communications links (not explicitly shown).
Method 304 is an exemplary embodiment of the present disclosure describing a method of maintaining communications between a monitoring client and one or more patient-care devices. In some embodiments, although method 304 includes a schedule of communications links, other schedules may be used, broadcasting, anycast, multicast or unicast may be used, routing algorithms may be used, a distance-vector routing protocol may be used, a link-state routing protocol may be used, an optimized link state routing protocol may be used, a path-vector protocol may be used, static routing with predefined alternative communications paths may be used, and/or adaptive networking may be used. For example, in some embodiments of the present disclosure, weights may be assigned to each communications path and Dijkstra's Algorithm may be used to communicate between the monitoring client 1 and one or more patient-care devices; the weights may be determined in any know way, including as a function of bandwidth, signal quality, bit-error rate, may be linear to the available data throughput or latency, and/or the like.

In an embodiment of the present disclosure, the facility services 8 and/or the drug adverse event network 9 may also include a Drug Error Reduction System (“DERS”). The DERS system may include a first set of predetermined criteria to trigger soft alarms and/or a second set of predetermined criteria to trigger hard alarms. Soft alarms may be overridden (e.g., turned off) by a caregiver using a user interface of the infusion pump 830, the user interface 808 of the hub 802, and/or the user interface of the monitoring client 1 (and may be only an audible and/or vibratory alarm) while hard alarms cause the treatment to cease until the source of the hard alarm is removed.
In yet an additional embodiment of the present disclosure, the DERS system may include a first set of predetermined criteria defining soft limits and/or a second set of predetermined criteria defining hard limits. The hard and soft limits define treatment limits, such as drug dosage limits based upon size, weight, age, other patient parameters, or other criteria. Soft limits may be overridden by a caregiver using a user interface of the infusion pump 830, the user interface of the monitoring client 1, and/or the user interface 808 of the hub 802 to start treatment despite that the treatment is outside of the first set of predetermined criteria while the hard limits prevent the treatment from starting until the settings are changed to confirm to the second set of predetermined criteria defining the hard limits.
In some embodiments, the patient-care devices 830, 810, 812, 814, 14, 15, 16, 17, and/or 148, the monitoring client 1, the remote communicator 11, and docks 102 and/or 804, and/or the hub 802 may include a secure data class, e.g., via an API.
Referring again to the drawings,
Optionally, the monitoring client 902, other monitoring client 4, and/or the remote communicator 11 may be used to send commands or requests to patient-care devices 14, 15, 16, 17, 35, 128, 904, 906, 908, 148 such as for example, a bolus amount, an infusion flow rate, a total fluid for delivery, a start time for drug delivery, a stop time for drug delivery or a flow-delivery-rate profile to the stackable infusion pump 904, the stackable syringe pump 906 and/or the other stackable patient-care device 908. In some embodiments, one or more of the monitoring clients 902, 4, 11 may be used to send commands or requests to the pill dispenser 128, such as, for example, a pill dispense command to dispense a pill, a pill-type, a pill dispensing schedule, and/or a max pill-dispensing criteria. The max pill-dispensing criteria may be a maximum amount of a medication that may be delivered within a predetermined interval of time; for example, certain medications are taken as needed (i.e., pro re nata), however, the medication may not be safe if taken in excess and the max pill-dispensing criteria may prevent the medication from being taken at unsafe levels by the patient, e.g., a predetermined amount during a predetermined interval of time.
Optionally, the patient-care devices 14, 15, 16, 17, 35, 128, 904, 906, 908, 148 may also communicate data back to the monitoring client 902, the other monitoring client 4 and/or the remote communicator 11 for: determining if an alarm or alert should be issued or sent; determining if the treatment or condition is safe for the patient; determining if the system 900 is operating properly or within predetermined bounds; and/or for displaying the data on a display of the monitoring client 902, the other monitoring client 4 and/or the remote communicator 11. For example, optionally, the stackable infusion pump 904, the stackable syringe pump 906, and/or the other stackable patient-care device 908 may communicate (where applicable): upstream pressure; changes in upstream pressure; pressure downstream to the patient 2; changes in pressure downstream to the patient 2; the presence or absence of air within an infusion line; an actual bolus amount delivered; an actual infusion flow rate; an actual total fluid delivered; an actual start time for drug delivery; an actual stop time for drug delivery; or an actual flow-delivery-rate profile to one or more of the stackable monitoring client 902, the other monitoring client 4 and/or the remote communicator 11. In another embodiment, the pill dispenser 128 may optionally communicate data back to the stackable monitoring client 902, the other monitoring client 4, and/or the remote communicator 11, such as for example, an actual pill dispensed, an actual pill-type dispensed, an actual pill dispensing schedule as dispensed, or whether or not a max pill-dispensing criteria was exceeded.
The data received from the patient-care devices 14, 15, 16, 17, 35, 128, 904, 906, 908, 148 may be analyzed for any predefined conditions to issue an alarm and/or an alert. For example, one or more of the monitoring clients 902, 4, 11 may use an increase in pressure downstream of the stackable infusion pump 904 and/or the stackable syringe pump 906 to be an indication of one of: excessive clotting, infiltration, occlusion or kinking of the tubing to the patient; or occlusion by other material within the IV bag 170. In response to the sudden increase in downstream pressure, one or more of the monitoring clients 902, 4, 11 may visually or audibly alarm or alert a user. Additionally or alternatively, a sudden decrease in pressure downstream to the patient 2 may be an indication that the tubing has become detached from the needle and/or the needle is now out of the patient; and, in response, one or more of the monitoring clients 902, 4, 11 may visually or audibly alarm or alert a user. One or more of the monitoring clients 902, 4, 11 may, optionally, send a command to one or more of the stackable infusion pump 902 and/or the stackable syringe pump 906 to stop delivery of fluid in response to the sudden increase and/or decrease of pressure downstream to the patient 2.
The stackable monitoring client 902, the stackable device 908, the stackable infusion pump 904, and the stackable syringe pump 906 may be daisy-chained together via connectors coupled to the top and bottom of each device. For example, the stackable syringe pump 906 may instead be stacked on top of the monitoring client 902 such that a bottom connector of the stackable syringe pump 906 electrically coupled to connectors on top of the monitoring client 902.
The daisy chain can be created, for example, through electrical conductors within each of stackable monitoring client 902, the stackable patient-care device 908, the stackable infusion pump 904, and the stackable syringe pump 906 such that a continuous electrical contact is maintained between each of these devices.
Additionally or alternatively, the stackable devices 902, 908, 904, 906 may optionally maintain wireless communications with each other. For example, the stackable monitoring client 902 may detect that daisy-chain conductors are electrically unresponsive because of an internal short within a stackable device of the stackable devices 902, 908, 904, 906, and the stackable monitoring client 902 can interrogate each of the stackable devices 908, 904, 906 to determine which device is faulted; after a determination is made, the stackable monitoring client 902 can wirelessly communicate with an isolated disconnect circuit within the faulted device of the stackable devices 902, 908, 904, 906 to electrically disengage the faulted device from the daisy-chained conductors. Additionally or alternatively, one or more of the stackable devices 902, 908, 904, 906 can alarm, send an alert, and/or display a message that one of the stackable devices 902, 908, 904, 906 is faulted and/or that one of the stackable devices 902, 908, 904, 906 is communicating wirelessly rather than via the daisy-chained, wired communications link.
Additionally or alternatively, each of stackable monitoring client 902, the stackable device 908, the stackable infusion pump 904, and the stackable syringe pump 906 may relay or retransmit information to a respective device below or above itself within the daisy chain. For example, the stackable infusion pump 904 may communicate all data received from the stackable syringe pump 906 by buffering the data within an internal memory and communicating the information when a signal is received from the stackable patient-care device 908 indicating the stackable patient-care device 908 is ready to receive additional data. In some embodiments, each item, component, device, patient-care device, dock, and computing device, numbered or unnumbered, as shown in
Additionally, in some embodiments, although some items, components, devices, patient-care devices, and computing devices, numbered or unnumbered, as shown in
Additionally or alternatively, although particular patient-care devices 904, 906, 908 are shown, other combinations, subsets, multiple ones of a particular patient-care device, or combinations thereof may be used. For example, in some embodiments, only a stackable infusion pump 904 is used of the patient-care devices, and, in this specific example, the other patient-care devices 906, 908 may be disabled, may not be present or available for system use, may be turned off, or may not be part of system 900 of

In some embodiments, a hub, a dock, a device, an insulin pump, an infusion pump, and/or a patient-care device may be, or have the ability of, a web connected remote interface which may include, but is not limited to, capability to download applications, download software updates, upload information and/or send information to various machines, including, but not limited to, through a web based secure portal and/or through electronic mail and/or by way of a wireless communications protocol. Thus, in various embodiments, the remote interface application may run on any capable device and is not limited to a so-called proprietary device. Further, in some embodiments, the remote interface may be Bluetooth enabled, or otherwise enabled, to communicate, for example, using radio frequency (“RF”) communication, with one or more devices which may include, but are not limited to, one or more of the following: hub, a dock, a device, an insulin pump, an infusion pump, a patient-care device, a Bluetooth or other communication device, a patient-care device, and/or any other device.
In some embodiments, a charging station may include a charging area for a hub, a dock, a device, an insulin pump, an infusion pump, and/or a patient-care device for the remote interface which may include a USB plug. In some embodiments, the charging station may include a USB port, and in some embodiments, may include a mini-USB port, allowing for the charging station to receive power, in some embodiments, for charging the hub, the dock, the device, the insulin pump, the infusion pump, the patient-care device, and/or the remote interface through a USB. Additionally and/or alternatively, the USB port may be configured for data transfer to/from a remote interface and/or the hub, the dock, the device, the insulin pump, the infusion pump, and/or the patient-care device by connection to a computer or other device and/or other computer-type apparatus. In embodiments including a USB port, whilst the remote interface is being charged, the system may call to a personal computer and/or web portal to check for updated software and if there is updated software available, may download software updates, e.g., via the USB connection. These updates may then be transferred to the hub, the dock, the device, the insulin pump, the infusion pump, and/or the patient-care device upon pairing.
Thus, the user may connect the remote interface of a hub, a dock, a device, an insulin pump, an infusion pump, and/or a patient-care device to a personal computer and/or, in some embodiments, upload data from the remote interface to a web portal or other. In some embodiments, this may be accomplished during “recharging” of the remote interface which, in some embodiments, may be done using a USB connection to the personal computer, which, in additional to charging/recharging the remote interface may synchronize and/or upload/download data from the personal computer, 1908 and/or web portal. At this time, the system may determine software updates for one or more of the devices and or for the remote interface are available. The user may select “download updates” and these may be downloaded to the remote interface of the a hub, a dock, a device, an insulin pump, an infusion pump, and/or a patient-care device, again, at the time of charging and/or at any time the remote interface is either connected, directly or indirectly, to the personal computer and/or to a web portal designed specifically for the system. As discussed above, the remote interface is capable of communication with the various devices. Thus, software updates may be communicated to any one or more device by the remote interface. This has many advantages, including, but not limited to, only having to connect the remote interface to the personal computer/web portal to both upload data/information from all of the devices and/or download updates and/or applications from the personal computer and/or from the internet/web portal to any of the devices. This may be desirable for many reasons, including but not limited to, the ability to efficiently and easily update all devices from one connection and/or the ability to view all of the data from all the devices on one location and/or the ability to download information and/or settings from the personal computer/web portal to any of the devices through the remote interface.
Thus, in some embodiments, as the personal computer/web portal contains all the information from all the devices, including, but not limited to, the remote interface, at any time, a new “remote interface” may be introduced to the system. This may be accomplished by connecting the new remote interface to the personal computer/web portal and downloading all the information regarding the system to the remote interface. In some embodiments, this may first require that the old remote interface be removed from “approved devices”, however, in other embodiments; the system may “allow” additional remote interfaces by permission from the user. Thus, the system includes the ability to download all the information and applications to any internet connected and/or remote interface capable of communicating to the devices and/or capable of connecting the personal computer and/or web portal.
This also allows the remote interface to download any application from the internet to any device in the system. Thus, in various embodiments of the system, a user can turn any apparatus (including some parameters such as ability to wirelessly communicate and connect to the personal computer and/or web portal) into a device that could control the various device, for example, the infusion pump and/or receive data from and/or control a CGM sensor/transmitter, and/or other analyte sensors, and/or other devices, such as a hub, a dock, a device, an insulin pump, an infusion pump, and/or a patient-care device. In some embodiments, the remote interface and/or the one or more applications on the remote interface may be password or other protected and is paired with the one or more devices, for example, paired with an infusion pump and/or CGM sensor and or one or more other devices.
In some embodiments, the information on the remote interface may be uploaded and/or synchronized with another device and/or a computer and/or machine, including, but not limited to, uploading the data to an internet site that may be password protected (web portal). Thus, a user may access the information from any device and or may download the information to any device including any device specific applications and therefore the user information may be downloaded to any device including, but not limited to, history, preferred settings, etc., information.
Act 602 establishes a communications link between a patient-care device and a monitoring server. Act 604 communicates the patient-care parameter to the monitoring server, e.g., over the local area network and/or the internet, through WiFi, through a monitoring client, one or more hubs, or a dock, etc. Act 606 de-identifies the patient-care parameter. Act 606 may be performed automatically and electronically, e.g., within the monitoring server 3 of
Act 703 establishes communications links between a monitoring server, e.g., monitoring server 3 of
Act 705 communicates a plurality of patient-care parameters from the plurality of patient-care devices to the monitoring server. Act 707 de-identifies the patient-care parameters, and act 709 stores the patient-care parameters in the monitoring server, e.g., within a database, such as an SQL database, a relational database, an associative database, and the like. Act 707 may be performed automatically and/or electronically. Act 711 treats a subset of patients of the plurality of patients with a treatment. For example, patients with high blood pressure may be treated with a medication designed to lower blood pressure. Act 713 analyzes a subset of the plurality of patients-care parameters associated with the plurality of patients to determine the efficacy of the treatment. For example, all patients that received the blood pressure medication of act 711 can have their blood pressure compared to a blood pressure reading after a predetermined amount of time, e.g., 6 months, to determine if the treatment was effective for one or more patients.
Method 801 includes acts 803-823. Each of the acts 803-823, in some embodiments, is optional. Act 803 receives one or more patient-care parameters associated with a patient-care device. The patient-care device of method 801 may be any patient-care device disclosed herein, for example, it may be one or more of patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148, of
Act 805 stores the one or more patient-care parameters in a non-volatile memory of the patient-care device. The patient-care parameters may be any values associated with patient care including patient-treatment parameters or patient-condition parameters, for example, an infusion rate for an infusion pump is a patient-treatment parameter.
Act 807 receives one or more operating parameters for the patient-care device. An operating parameter may be anything related to the operation of the device. For example, an operating parameter may be a limit on the speed of a motor of an infusion pump, an infusion pump speed, a wattage limitation on wireless communications, a battery discharge rate or rate limit, an update frequency, and the like. Act 809 stores the one or more operating parameters in the non-volatile memory of the patient-care device.
Act 811 calculates one or more additional operating parameters for the patient-care device. The calculated operating parameters are any parameters calculated for operating the patient-care device, for example, a gain coefficient of a proportional-integral-derivative (“PID”) control loop that has adaptive gain coefficients used in automatic gain control. Act 813 stores the one or more additional operating parameters in the non-volatile memory of the patient-care device.
Act 815 determines that operation of the patient-care device has been interrupted, for example, power has been lost to the patient-care device, a fault has occurred in the patient-care device, a brown-out CPU reset has occurred, and the like. Act 817 determines that operation of the patient-care device can resume.
Act 819 loads the one or more received or calculated operating parameters into a working memory of the patient-care device; and, act 821 loads the one or more patient-care parameters into the working memory of the patient-care device. Act 823 resumes operation of the patient-care device.
Turning now to
Act 902 positions a monitoring client having a user interface (e.g., a display, touchscreen, a display, buttons, accelerometer for user input, and the like) within an operational distance of a patient-care device. Act 904 displays the identity of the patient-care device on the user interface. The patient-care device may be identified by, for instance, a serial number, a device type, or a visual display on the user input of the patient-care device using standard or custom discovery protocols. Act 906 selects the patient-care device for pairing using the user interface. For example, a user in act 906 may touch a touchscreen of the monitoring client to indicate selection of the patient-care device.
Act 908 pairs the patient-care device to the monitoring client. For example, the paring of the patient-care device to the monitoring client may utilize Bluetooth, Bluetooth Low Energy (I.E.E.E. 802.15.1), WiFi, infrared communications, near field communication (NFC ISO 13157), IR communication, or optically. A custom pairing protocol may be used as well, as will be apparent in light of this disclosure, which may or may not employ the use of handshaking sequence. Act 910 communicates patient-care parameters between the patient-care device and the monitoring client, e.g., so that the patient-care device may be controlled or monitored by the monitoring client.
Act 912, optionally, operatively communicates additional patient-care parameters with another patient-care device through the patient-care device. In act 912, if the patient-care device is operatively coupled to or is in operative communication with another patient-care device, the patient-care device can act as a relay or router so that the monitoring client can communicate with the another patient-care device. Additionally or alternatively, the patient-care device may use information from another patient-care device for its operation, for example, an infusion pump may use a flow rate as determined by a flow rate meter or temperature from a temperature probe, and/or the infusion pump may relay information from the flow rate meter to a monitoring client. Additionally, the monitoring client can optionally communicate with multiple patient-care devices coupled to the paired patient-care device, either in parallel or in serial. Additionally or alternatively, in some embodiments of the present disclosure, in method 900 the monitoring client communicates with the patient-care device using an intravenous tube. The communications may occur via an electrical conductor embedded into or attached to the intravenous tube, via electrical communication using the fluid within the intravenous tube as a conductive medium, using sounds waves traveling through the intravenous tube, or optically by using the fluid within the tube as an optical waveguide. The communication via the intravenous tube may be used to set-up pairing (e.g., between a monitoring client, a hub, a dock, a patient care device and/or a system monitor with one or more of a monitoring client, a hub, a dock, a patient care device and/or a system monitor) using another communications link, e.g., Bluetooth, Bluetooth Low Energy, WiFi, etc.
In yet additional embodiments of the present disclosure, the pairing from a first device (e.g., a monitoring client, hub, patient-care device, or system monitor) with a second device (e.g., a monitoring client, hub, patient-care device, or system monitor) may be configured and/or initialized using a first communications link such that the devices are paired using a second communications link; for example, near-field communications or IR communications may set up pairing between the devices using Bluetooth, Bluetooth Low Energy, or WiFi, for example. The pairing setup (e.g., via near-field communications or IR communications) may prompt a request on a monitoring client, hub, patient-care device, and/or system monitoring requesting user confirmation of the device pairing, e.g., pairing via Bluetooth, for example. In some embodiments, when a patient-care device is paired to a hub, monitoring client, and/or dock, the ID and software version number is sent to the hub, monitoring client, and/or dock, which checks with a server, e.g., the monitoring server 3, middleware, the cloud server, or other server to determine if the software on the patient-care device is up-to-date; if the software is not up-to-date, the hub, monitoring client, dock, or the patient-care devices itself (e.g., directly) downloads updated software to program the patient-care device. The patient-care device may notify the user if the software is up to date and/or may give the user the option on the touch screen to optionally update the patient-care device if the software is not up to date. The communications link that sets up the pairing (e.g., NFC) and/or the communications link that uses the pairing (e.g., Bluetooth or Bluetooth Low Energy) may communicate the updated software, the ID, the software version number, provide the notification, etc. One pairing that may be used, e.g., with a pump patient-care device or insulin pump, may be found in: (1) the patent application entitled “INFUSION PUMP METHODS AND SYSTEMS” to Mandro et al., filed Mar. 25, 2010, and having the Ser. No. 12/731,843, (2) the patent application entitled “METHODS AND SYSTEMS FOR CONTROLLING AN INFUSION PUMP” to Bryant et al., filed Apr. 4, 2009, and having the Ser. No. 12/416,662, and/or (3) the patent application entitled “INFUSION PUMP ASSEMBLY” to Kamen et al., filed Dec. 31, 2009, and having the Ser. No. 12/347,985, the entire contents of all three of which are hereby incorporated by reference in their entirety.
The wearable system monitor of method 10000 may be the wearable system monitor 131 of
The patient-care device of method 1000 may be any patient-care device disclosed herein, such as patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148, of
The system monitor of method 1000 may be used with system 100 of
Act 1014 identifies a caregiver (i.e., provider) using one or more of: a voice-recognition algorithm, a facial-recognition algorithm, a barcode, an RFID tag, near-field communications, simple login, secure signatures, and the like. For example, the identification of the caregiver in act 1040 may be done by a monitoring client, a monitoring-client docking station, a device docking station, by a communications module, other dock, or hub using an onboard camera and/or a microphone. Also, as a safety check, a monitoring client, a hub, dock, or patient-care device may request that a user enter in font as displayed to guard against font corruption errors. Additionally or alternatively, in some embodiments, if after one or more failed logins or verifications, the device may take a picture and store the picture; the picture may be transmitted for storage in a middleware server. Act 1016 logs the presence of the caregiver in one or more of the devices 1002-1012. The log entry may be stored on the any one of the devices 1002-1012, a patient-care device described herein, a monitoring client described herein, a wearable system monitor described herein, a remote communicator described herein, and/or a hub described herein. The log of act 1016 can be for caregiver compliance, diagnostic purposes, and the like. For example, if a caregiver is scheduled to appear and does not, the act of 1016 may log the non-appearance of the caregiver at the scheduled time.
The facial-recognition algorithm of act 1014 may relay on any facial features of the caregiver such as analyzing the relative size, shape, a position of the eyes, nose, jaw, cheekbones, or other facial features. The facial-recognition algorithm of act 1014 may use three-dimensional face recognition, skin texture analysis, or other facial-recognition algorithm. Additionally or alternatively, in some embodiments, the voice-recognition algorithm of act 1014 may use hidden Markov models, dynamic-time-warping based speech recognition, or other voice-recognition algorithm(s).
Act 1018 detaches the wearable system monitor from a wearable dock. For example, the system monitor 131 of
The timer of act 1020 keeps track of the amount of time the wearable system monitor is out of its dock. Act 1022 stops a treatment if a predetermined amount of time has elapsed after the wearable system monitor has been undocked from the wearable dock. For example, the wearable system monitor of method 1000 may signal an infusion pump to stop pumping. When the wearable system monitor is docked again, act 1024 resumes the treatment if the treatment was interrupted, e.g., from undocking the wearable system monitor from its wearable dock after the predetermined amount of time has elapsed.
As previously mentioned, act 1018 detaches the wearable system monitor from the wearable dock. Act 1026 identifies a patient using, for example, one or more of: a voice-recognition algorithm, a facial-recognition algorithm, a barcode, an RFID tag, near-filed communications, simple login, caregiver entry, and the like. Act 1026 may be similar to act 1014, may utilize the same software as utilized in act 1014, and/or may utilize one of the devices 1002-1020. In some embodiments, however, note that the identification procedure for a patient can include more than the identification of the caregiver by using, for example, biometrics or other identifying patient-specific information. Such patient identification standards may be used to ensure a particular treatment is being given to the correct patient and/or to provide compliance with given regulations. Act 1014 and/or 1026 may be performed using a passkey device on the patient and/or caregiver.
Act 1028 determines if the caregiver is authorized to pair the wearable system monitor, e.g., pair the wearable system monitor with a patient-care device. If the caregiver is not authorized, then the method 1000 prevents additional pairing (or editing of the pairing settings) of the wearable system monitor. If the caregiver is authorized to pair the wearable system monitor, act 1030 allows the caregiver to select one or more patient-care devices for pairing with the wearable system monitor. Caregiver authorization can be used, for instance, to ensure a particular treatment is being given to the correct patient and/or to provide compliance with given regulations.
The caregiver may be provided a list of patient-care devices that are available for pairing on one or more user interfaces of the devices 1002-1012. During act 1030, the caregiver selects a wearable system monitor (e.g., the patient-wearable system monitor of act 1018) and a patient-care device for pairing together. Act 1032 pairs the wearable system monitor with the patient-care device, and act 1034 logs the pairing of act 1032 in the wearable system monitor including the identity of the caregiver and the patient. In an additional specific embodiment, the pairing of the wearable system monitor with the patient-care device may be used with parallel or serial pairing of the patient-care device with another device (e.g., a monitoring client, a hub, another patient-care device etc.) As will be appreciated in light of this disclosure, any suitable pairing protocol (e.g., Bluetooth or IEEE 802.11) can be used. Additionally or alternatively, act 1034 can log the pairing into one or more of the devices 1002-1012.
Act 1036 reattaches the wearable system monitor to the wearable dock. Act 1038 identifies and authenticates the wearable docking using the wearable system monitor, e.g., to determine if the wearable system monitor and the wearable dock are authorized for docking together. For example, act 1038 may ensure that the wearable system monitor is docked to a wearable dock of the correct patient. If, for example, the wearable system monitor was docked to a wearable dock of the wrong patient, the wearable system monitor can recognize the error, preclude the associated treatment from proceeding by signaling the patient-care device associated with the patient-care device to stop operating (in some embodiments), and send an alert to a monitoring client, e.g., the monitoring client 1, 4, or 11 of
In some specific embodiments, when a caregiver is identified in act 1016 and/or the patient is identified in act 1026, the caregiver may update treatment settings, e.g., on a monitoring client, a hub, a remote communication or on the patient-care device.
The monitoring client of method 1100 may be one or more of monitoring clients 1, 4, or 11 of
Although method 1100 describes using a user-interface template with a monitoring client, the monitoring client may be substituted by a hub, a communications module, another patient-care device, or other sufficient device having a user interface. The user-interface template of the user interface of method 1100 provides a predefined display with specific fields for displaying patient-care parameters. For example, a user-interface template for an infusion pump may define certain fields for displaying on a GUI, such as the present fluid-flow rate. The user-interface template may also define an area on a display of the monitoring client for displaying the present fluid-flow rate as received from the infusion pump. The user-interface template may include layout information, such as: instructions how to display information; a description of various widgets; various widgets; graphs; labels for the graph axes; labels for the display; buttons; and/or labels to provide the user with control or visual information of one or more patient-care devices. The user-interface template may be a template describing a QT-based template, and/or may use HTML or CSS.
Act 1102 identifies or selects a patient-care device for communication with a monitoring client having a user interface. For example, in act 1102, the monitoring client may automatically identify a predetermined infusion pump that has been previously designated by a provider for treatment of a patient. Additionally or alternatively, in act 1102 a provider may be given a list of patient-care devices to select from for displaying on the user interface of the monitoring client information concerning operation of the selected patient-care device(s).
Act 1104 determines if the patient-care device has a stored user-interface template. For example, an infusion pump may include flash memory with a user-interface template stored therein. If the patient-care device has a stored user-interface template, act 1106 communicates the stored user-interface template from the patient-care device to the monitoring client having the user interface. Act 1108 displays the user-interface template on the user interface of the monitoring client. Act 1110 communicates patient-care parameters between the patient-care device and the monitoring client. Act 1112 displays the patient-care parameters on the displayed user-interface template in accordance with the user-interface template. For example, a user-interface template for an infusion pump may include a space for the present infusion rate; act 1112 displays, in this example, the present infusion rate (a patient-care parameter) on the display using the user-interface template.
If act 1104 determines that no patient-care device has a stored user-interface template, the method 1100 will determine if the monitoring client has a user-interface template for use for displaying the patient-care parameters of the patient-care device; additionally or alternatively, act 11004 may issue an alarm via the monitoring client and/or the patient-care device. Act 1114 determines the type of the patient-care device. If the type is determined, act 1116 determines if a user-interface template is stored within the monitoring client in accordance with the type of the patient-care device. If there is a user-interface template, act 1118 displays the user-interface template on the user interface of the monitoring client. Act 1120 communicates patient-care parameters between the patient-care device and the monitoring client. Act 1122 displays the patient-care parameters on the displayed user-interface template in accordance with the user-interface template. For example, patient-care parameters, such as an infusion rate, may be displayed in predefined areas of the user interface as designated by the user-interface template.
If the type is not determined in act 1114, or a user-interface template is not located within the monitoring client based upon the determined type, then act 1124 displays a selectable list of a plurality of user-interface templates on the user interface of the monitoring client; additionally or alternatively, act 1114 may issue an alarm or alert via the monitoring client and/or the patient-care device. Act 1126 allows a user to select a user-interface template from the plurality of user-interface templates using the user interface of the monitoring client. Act 1128 displays the user-interface template on the user interface of the monitoring client. Act 1130 communicates patient-care parameters between the patient-care device and the monitoring client. Act 1132 displays the patient-care parameters on the displayed user-interface template in accordance with the user-interface template.
In some embodiments of the present disclosure, the patient-care device of method 1100 may also store one or more fonts for display on the monitoring client, e.g., using the user-interface template described above. The fonts may be stored in any format, such as JPEGs, BMPs, image formats, pre-stored fonts, and the like and may be transmitted for use within the field to provide an indication of the operating parameter, (e.g., rather than transmitting a value, an image is transmitted showing a number or value which is then displayed on the monitoring client). In some embodiments, fonts stored within the monitoring client may be used such that a value of the operating parameter is sent to the monitoring client for display within the template using the fonts stored in the monitoring client.
Method 1134 includes acts 1136-1146. In some embodiments, each of the acts 1136-1146 is optional. The monitoring client of method 1134 may optionally be one of the monitoring clients 1, 4, or 11 of
Act 1136 docks a patient-care device into a dock. For example, an infusion device 7 of
In act 1140, the monitoring client queries a server for an application to control the patient-care device (e.g., to set an infusion rate). The monitoring client downloads the application in act 1142. The communications between the monitoring client and the server may be encrypted. For example, the server may encrypt the application prior to sending to the monitoring client, and the monitoring client can decrypt the application using a sufficient encryption key. Additionally or alternatively, all communications may be encrypted. The monitoring client executes the application during act 1144. In act 1146, the monitoring client is communicatively and operatively coupled with the patient-care device through the application by executing the application on one or more processors. The monitoring client may place the application in a sandbox (as described below). In one such embodiment, the application includes an operative set of processor executable instruction configured for execution by one or more processors on the monitoring client. The application may include instructions to display a user interface on a display of the monitoring client, e.g., using the user interface template of method 1100 of
The request may optionally originate from any authorized, authenticated, and/or identified monitoring client, such as, for example, a monitoring client 1 or 4 of
Act 1202 submits a request for a patient-care device using a user interface of a monitoring client. For example, using the touchscreen of the monitoring client 1 of
Act 1204 is optional, and act 1204 displays “pending request” on the user interface of the monitoring client. Act 1206 formats the request for a patient-care device. For example, act 1206 may prepare the request such that it conforms to the communications requirements of the patient-care device.
Act 1208 determines a check value of the request. For example, a cyclic-redundancy-check algorithm is used to determine a check value that corresponds to the request. The check value calculated by the cyclic-redundancy-check algorithm is dependent upon the request. A change in one bit of the request will also change the check value as calculated by the cyclic-redundancy-check algorithm. Likewise, changing several bits will also change the check value. Additionally or alternatively, in other embodiments, a parity bit (even or odd) or other data integrity checks may be used.
Act 1210 appends the check value to the request. Action 1212 is optional, and act 1212 requests confirmation from the user for communicating the request using the user interface. The request for confirmation may be a pop-up dialog box on a touchscreen that displays “confirm infusion rate of 90 milliliters/hour?” with a box for selecting “confirmed.” The text and format shown in act 1212 may be of a different font, different font size, and/or different display position than other displayed information, e.g., as displayed during the entering of the request or otherwise, to provide an additional safeguard against bad display pixels, a corrupted font table, user misunderstanding, and the like. Act 1214 confirms the request for communication of the request using the user interface. The user can touch the “confirmed” box to confirm the request for communication of the request, according to some embodiments of the present disclosure.
Act 1216 communicates the request to the patient-care device. The communication may be made via wired, wireless, guided, or fiber optic communications, or the like. The patient-care device receives the request during act 1216. During transit of the request, it is possible that one or more bits in the request have been corrupted, e.g., a bit has changed its value, a bit has been lost, a bit has been added, and the like; this or other data corruption is undesirable.
Act 1218 of method 1200 facilitates the detection of corrupted data. During act 1218, the patient-care device verifies the check value in accordance with the request. In act 1218, the patient-care device may use the same cyclic-redundancy-check algorithm as in act 1208 on the request to calculate an additional check value. The check value in act 1216 as calculated by the patient-care device will be identical to the check value calculated in act 1208 only if the data in the request is identical. That is, the check value in act 1216 and the check value in act 1208 will be different only if the data of the request has become corrupted, has fewer or more bits, or otherwise is not identical to the digital data used to determine the check value of act 1208.
If the check value of the request was not verified, in act 1222 the patient-care device requests retransmission of the request from the monitoring client. Although
In alternative embodiments, the request in act 1218 is additionally sent back to the monitoring client after verification from the patient-care device and may include additional CRC checking during the transmission. The patient-care device during verification may perform, in this alternative embodiment, checks to determine if the request is within predetermined ranges (e.g., the infusion rate for the particular drug is safe, etc.). The monitoring client, in this alternative embodiment, can either compare the request as received from the patient-care device with the original request as stored in memory (the requests may be associated with each other), and/or the monitoring client can display the request to the user for confirmation. The request for confirmation may be a pop-up dialog box on a touchscreen that displays “confirm infusion rate of 90 milliliters/hour?” with a box for selecting “confirmed.” The text and format shown in this alternative embodiment for the confirmation may be of a different font, different font size, and/or different display position than other displayed information, e.g., as displayed during the entering of the request or otherwise, to provide an additional safeguard against bad display pixels, a corrupted font table, user misunderstanding, and the like. In this alternative embodiment, the user can confirm the request for communication of the request using the user interface. The user can touch the “confirmed” box to confirm the request for communication of the request, according to some embodiments of the present disclosure.
Thereafter, in this alternative embodiment, the request is resent to the patient-care device for performing; additionally or alternatively, in this alternative embodiment, an action message is sent to the patient-care device, and the action message contains information linking it to the original request (e.g., “This is the “action” for the 90 milliliters/hour request that was just sent”).
The patient care device may be any patient-care device described herein, such as one of the patient-care devices 7, 14, 15, 16, 17, 35, 126, 128, 130, 148, of
The dock 1304 may include a shaped receiving portion for receiving the monitoring client 1302 for connecting electrical contacts of the monitoring client 1302 to the docket 1304 through a cable 1308. The cable 1308 may be integrated together with the dock 1304 and/or the monitoring client 1302. The cable 1308 may provide, for instance, USB or other standard communications between the dock 1304 and the monitoring client 1302.
The dock 1304 optionally includes a processor 1301, sensors 1309, a watchdog 1310, a charger 1312, a battery 1314, and an alternating-current (“AC”) power cord 1316. The processor 1301 controls the operation of the dock 1304. A patient-care device 1318 is dockable to the dock 1304. System 1300 also includes a wireless dock 1306 having a patient-care device 1320 docked thereto. The wireless dock 1306 may be identical or similar to the dock 1304, however, the wireless dock 1306 wirelessly communicates with the monitoring client 1302, in some embodiments.
The battery 1314 can power the dock 1304 and the patient-care device 1318 when the AC power cord 1316 is unplugged from an AC outlet (not shown). In some embodiments, the dock 1304 may be the sole source of power for the monitoring client 1302 or the patient-care device 1318. Additionally or alternatively, the monitoring client 1302 and/or the patient-care device 1318 may include an on-board battery or a separate AC power cord (not shown).
In some example embodiments, the dock 1304 may provide IEC-60601 compliant power to the patient-care device 1318. Additionally or alternatively, the dock 1304 can provide a variable DC voltage as requested by the patient-care device 1318. For example, the dock 1304 may include a programmable buck-boost power supply (not shown) that can provide a DC voltage from 1 Volt to 24 Volts as requested by the patient-care device 1318 for a specific connector pin of a connector 1322.
The battery 1314 may be charged by the charger 1312 when the power cord 1316 is plugged into an AC outlet (not shown). The battery 1314 provides uninterrupted power to the patient-care device 1318 when the AC power cord 1316 is unplugged from an AC outlet (not shown). For example, the patient-care device 1318 may be an infusion pump which continues to operate after the AC power cord 1316 is unplugged because the battery 1314 automatically supplies replacement power to the patient-care device 1318 when the AC power cord 1316 is unplugged.
The sensors 1308 may optionally include one or more of an ambient temperature sensor, an ambient pressure sensor, an ambient humidity sensor, and the like. The sensors 1308 may optionally include redundant sensors, such as two temperature sensors, and the dock 1304 may use the redundant sensors to determine if one or both has malfunctioned, e.g., by comparing the readings of the two sensors to each other. The dock 1304 may communicate with the sensors 1308 and/or other peripherals to ensure their proper operation, to perform data integrity checks, to provide the patient-care device 1318 with their measurements, e.g., the ambient temperature.
The watchdog 1310 can optionally ensures that the patient-care device 1318 is properly operating by performing interrogations mentioned above, monitoring the outputs of the patient-care device 1318 to determine if they are within predetermined ranges (e.g., physically possible or likely ranges), have feedback that is in accordance with applied input, and is otherwise operating properly. Additionally or alternatively, the system monitor 13010 may optionally monitor the operation of the monitoring client 1302 through the cable 1308. Although one watchdog 1310 is described herein, one or more watchdogs 1310 may be used, e.g., a plurality of watchdogs 1310. In some example embodiments, the patient-care device 1318 communicates with the watchdog 1310 at fixed intervals. The fixed intervals are optionally configurable using a user interface of the monitoring client 1302 or using a computer attached to the cable 1308. If the patient-care device 1318 fails to communicate with the watchdog 1310 during the fixed interval, the watchdog 1310 determines that an error has occurred within the patient-care device 1318 and issues an alert or alarm, e.g., an audible sound using a speaker 1324 or flashes an LED 1326 red. The action for response to not receiving a communication within the interval may be configurable and/or program, e.g., using a user interface of the monitoring client 1302 or using a computer attached to the cable 1308; for example, for non-critical patient-care devices, a failure to respond to the watchdog 1310 may cause the LED 1326 is flash RED, and an action to a critical patient-care device may additionally cause the dock 1304 and/or monitoring client 1302 to audibly and visually alarm and sent a notification to a nursing station and/or a remote communicator, e.g., remote communicator 11 of
Additionally or alternatively, the watchdog 1310 may ensures that the monitoring client 1302 is properly operating by requiring it to communicate with the watchdog 1310 at a fixed, predetermined, or preprogrammed interval. If the monitoring client 1302 fails to communicate with the watchdog 1310 during the fixed interval, the watchdog 1310 may determine that an error has occurred within the monitoring client 1302 and issues an alert or alarm similar to the one described above with regards to the patient-care device 1318, e.g., an audible sound using a speaker 1324 or flashes an LED 1326 red. In some embodiments, a speaker within the monitoring client 1302 may issue an audible alert. In some embodiments, a speaker within the monitoring client 1302 may serve as a backup speaker to the dock 1304, and the speaker 1324 of the dock 1304 may serve as a backup speaker to the monitoring client 1302.
The charger 1312 can charge the battery 1314 using AC power supplied through the AC power cord 1316. Additionally or alternatively, the charger 1312 can charge a battery 1328 within the patient-care device 1318.
In some embodiments, the wireless dock 1306 may include the same hardware as the dock 1304 and may or may not include the AC power cord 1316. For example, the wireless dock 1306 may include a plurality of contacts for positioning the wireless dock in a recharging cradle that includes a plurality of contacts that engage the contacts of the wireless dock 1306 for charging a battery therein.
The dock 1404 receives AC power 1420 from an AC outlet 1422. The dock 1404 is in operative communication with the monitoring client 1402 using a monitoring-client adapter 1424. The monitoring-client adapter 1424 is coupled to the dock 1404 through UI connectors 1426, 1428. The UI connectors 1426, 1428 provide power to the monitoring-client adapter 1424 and data through a USB link. The monitoring-client adapter 1424 is coupled to the monitoring client 1402 through several connectors 1430, 1432, 1434, 1436. Two of the connectors 1430, 1434 provide power from the monitoring-client adapter 1424 to the monitoring client 1402, while two other connectors 1434, 1436 provide a USB connection therebetween to facilitate digital communications between the dock 1404 and the monitoring client 1402. Note that other embodiments may employ connections other than the USB-type.
Connectors 1438-1450 allow the dock 1404 to operatively provide power to the large volume pump 1406, the syringe pump 1408, and sensors 1410. Additionally or alternatively, connectors 1438 and 1440 provide serial communications between the dock 1404 and the large volume pump 1406; connectors 1442 and 1444 provide serial communications between the large volume pump 1406 and the syringe pump 1408; and, connectors 1446 and 1448 provide serial communications between the syringe pump 1408 and the sensors 1410. Connector 1450 provides optional expansion for additional devices (not shown).
System 1400 shows a daisy-chained system for coupling together several devices together. Each device either digitally routes data destined for another device to a subsequent device, or each device includes electrical conductors such that both of its connectors include electrical connections to respective pins.
The dock 1404 can communicate with the wireless sensor 1414 using, for example, Bluetooth, Bluetooth low energy, Zigbee, Xbee, ANT, ANT Plus, and the like. The sensors 1412, 1414, and/or 1410 may be a patient-monitoring device, or one or more environment sensors, such as a temperature sensor, humidity sensor, a camera, a microphone, an ambient light sensor, a vibration sensor, and the like.
The server 1416 can communicate with the hospital information system 1418. The server 1416 provides a WiFi router such that the dock 1404 is in operative communication with the hospital information system 1418. Information may be transferred to and from the hospital information system 1418 through the server 1416, which can translate protocols of the dock 1404 to and from the hospital information system 1418 or Health Level 7 (“HL7”). The server 1416 (and/or the hospital information system 1418) may include a drug error reduction system (“DERS”) system that checks to determine that any treatments being applied to a patient using the system 1400 is safe for the patient. The server 1416 may be the monitoring server 3, and the hospital information system 1418 may be the facility services 8 of
Dock 1404 includes an AC/DC converter 1452 for receiving the AC power 1420 (see
The DC power 1454 is received at the DC power entry 1456, which may be a connector to connect the positive and negative leads of the DC power 1454 to power and ground planes of a PCB board, respectively. The DC power entry 1454 provides power to the circuitry of the dock 1404. The DC power entry 1456 may also receive wireless power 1458.
The power received via the DC power entry 1456 is sent to charging circuitry 1460. The charging circuitry 1460 charges a primary battery 1462 and a backup battery or super-capacitor 1464. The charging circuitry 1460 may employ various charging techniques, for example, a constant-current/constant-voltage charging algorithm.
The dock 1404 includes a primary processor 1466 and a safety processor 1468. The primary processor 1466 is powered by the primary battery 1462. The safety processor 1468 is also powered by the primary battery 1462, but also can receive power from the backup battery or super-capacitor 1464.
In this example embodiment, the primary processor 1466 interfaces with a barcode reader 1470, a camera 1472, dock sensors 1474, a speaker 1476, a WiFi transceiver 1478, a Bluetooth transceiver 1480, a USB controller 1482, LED status lights 1484, and three internal expansion slots 1486, 1488, and 1490 (each of which is optional).
The internal expansion slots 1486, 1488, and 1490 can receive additional circuitry. For example, as shown in
The safety processor 1468 provides a watchdog function to the primary processor 1466. For example, the safety processor 1468 can communicate with the primary processor at predetermined intervals, or expects a communication from the primary processor 1466 at predetermined intervals. If the safety processor 1468 does not receive the expected response or communication, it may determine that an error has occurred. The safety processor 1468 in response to the error may indicated a fault using LED Fault status lights 1401, generating an audible sound using a backup speaker 1403, or vibrate the dock 1404 using a vibration motor 1405. As will be appreciated in light of this disclosure, numerous fault notifications (e.g., telephone call, email, text message, etc) can be issued to numerous personnel (e.g., nurses and/or physicians, facility maintenance, etc).
The safety processor 1468 can monitor the power supplied through the device connector using current sensing circuitry 1407. If the safety processor 1468 determines that the current supplied to the device connector 1438 exceeds a predetermined threshold or is otherwise out of specification, the safety processor 1468 signals power enable circuitry 1409 to disengage the power supplied from the primary battery 1462 to the device connector 1438. The power enable circuitry 1409 may include relays, switches, solid-state switches, contactors, and the like to connect and disconnect the primary battery 1462 from the device connector 1438.
The primary processor 1466 is also electrically coupled to an optional charge-state display 1411 and an optional display 1413. The charge-state display 1411 can display the charge state of the primary battery 1462. The display 1413 may be a touchscreen and/or may display the operational status of the dock 1404. The dock 1404 receives user input via optional buttons 1415.
The communications/ranging module 1492 can communicate with other communications/ranging modules 1492, e.g., on a patient-care device, other dock, or monitoring client, to determine the distance therebetween. For example, two communications/ranging module (e.g., communications/ranging module 1492 and another communications/ranging module), may wirelessly communicate, for example, via ultrasound, RF, UHF, electromagnetic energy, optically, and the like, to determine the distance between them. In accordance with one embodiment, one or more of a patient-care device, a monitoring client, a patient's watchdog, a remote communicator, etc. may not operate unless each of them having a communications/ranging modules 1492 determines they are within a predetermined distance relative to each other.
In an embodiment, the monitoring client 2102 is capable of receiving information about each patient-care device with which it is linked either directly from the device itself, or via a docking station, such as, for example, the dock 2104 onto which the patient-care device may be mounted. The dock 2104 may be configured to receive one or more patient-care devices via a standardized connection mount, or in some cases via a connection mount individualized for the particular device. For example, in
The dock 2104 may be configured to electronically identify the particular patient-care device being mounted on the docking station, and to transmit this identifying information to monitoring client 2102, either wirelessly or via a wired connection. Additionally, the particular patient-care device may be preprogrammed with treatment information (e.g., patient-treatment parameters such as an infusion rate for a predetermined infusion fluid) that is transmitted to the monitoring client 2102. In some embodiments of the present disclosure, the monitoring client 2102 communicates with EMR records to verify that the preprogrammed treatment information is safe for an identified patient and/or the preprogrammed treatment information matches the prescribed treatment stored in the EMR records.
In some embodiments, the drip detection device 2112 may communicate with the monitoring client 2102 either wirelessly or in a wired connection. If an aberrant fluid flow condition is detected (e.g., because the tubing to the patient has become occluded), a signal may be transmitted to monitoring client 2102, which (1) may display the flow rate of fluid from fluid container 2118 in a user interface either locally on monitoring client 2102, or more remotely to a user interface at a nurse's station or a handheld communications device, (2) may trigger an auditory or visual alarm, (3) may alter the rate of infusion of a pump 2108 connected to bag 2118, by either terminating the infusion or otherwise changing the pumping rate, or (4) may cause an audible alarm (and/or vibration alarm) on the infusion pump 2106. The alarms may occur simultaneously on several devices or may follow a predetermined schedule. For example, when an occlusion occurs in a line connected to the infusion pump 2106, (1) the drip detection device 2112 alarms using its internal speaker and an internal vibration motor, (2) thereafter, the infusion pump 2106 alarms using its internal speaker and an internal vibration motor, (3) next, the monitoring client 2102 alarms using its internal speaker and an internal vibration motor, and (4) finally, a remote communicator 11 (e.g., see
In some embodiments, an individual pump may be programmable to allow for continued operation at a predetermined pumping rate should communications fail between the monitoring client 2102 and the pump, either because of a malfunction in the monitoring client 2102, in the communications channel between the monitoring client 2102 and the pump, or in the pump itself. In some embodiments, this independent function option is enabled when the medication being infused is pre-designated for not being suspended or held in the event of a malfunction in other parts of the system. In some embodiments, a pump programmed to operate independently in a fail safe mode may also be configured to receive information from a drip detection device 2112 directly, rather than through a monitoring client 2102. With this option, the pump may be programmed, in some embodiments, to stop an infusion if the drip detection device 2112 detects an aberrant flow condition (such as, e.g., a free-flow condition or an air bubble present in the infusion line). In some embodiments, one or more of the pumps 2106, 2108, and 2110 may have internal fluid flow meters and can operate independently as a stand-alone device.

In this specific embodiment, the microbags 4411 and 4407 may include an integrated flow rate meter, a drip counter, an integrated drip chamber, a communication link to communicate via the IV tube, and may include a power supply with or without a battery or AC/DC converter to power the electronics thereon. The IV communications may occur via an electrical conductor embedded into or attached to the intravenous tube, via electrical communication using the fluid within the intravenous tube as a conductive medium, using sounds waves traveling through the intravenous tube, or optically by using the fluid within the tube as an optical waveguide. The IV communications may be encrypted, e.g., using symmetric or asymmetric key encryption. The microbags 4411 and/or 4407 may include an optical communicator that communicates data (via an infusion tube) to an infusion pump describing a flow rate and/or the contents of the liquid contained therein. The microbags 4411 and/or 4407 may include an RFID and/or NFC tag at a pigtail that can interface with a drip counter which a reader may use to determine the contents and/or volume of the liquid inside of the microbags 4411 and/or 4407 (e.g., the information is encoded therein). The microbag 4411 and/or 4407 may include a bubble sensor (capacitive or ultrasonic) which communicates the estimation of bubble sizes to a monitoring client and/or hub. The microbags 4411 and/or 4407 may need to be within a predetermined distance from the patient as determined by NFC, and/or a ranging module before it will operate (e.g., open a valve and/or active an integrated flow rate meter, drip counter or drop chamber, a communication link, power supply etc.)
The components 3402, 3404, 3406, and 3408 may be implemented, for example, in hardware, software, software in execution, in digital logic, firmware, bytecode, in virtualization, using PLDs, FPGAs or PLAs, using one or more processors, or some combination thereof. For example, the components 3402, 3404, 3406, and 3408 may be an operative set of processor executable instruction configured for execution by one or more processors on a device 3401, e.g., the device 3401 may be a monitoring client disclosed herein. The components 3402, 3404, 3406, and 3408 may be stored on non-transitory, computer readable medium readable by one or more processor for execution by the one or more processors, e.g., the one or more processors may be in operative communication with the non-transitory, computer readable medium.
The user interface 3402 may be a touchscreen (or processor executable code to control a touchscreen) configured to receive user input, e.g., an infusion rate. The user interface 3402 may be used by an operator to set up treatment parameters and to see treatment status. The user interface 3402 can be used to adjust patient-treatment parameters during therapy, for guidance on the setup of the system 3400, and/or for post-treatment disassembly of the system 3400. The user interface 3402 may include a touchscreen and buttons. The user interface 3402 may be a resident software application on the device 3401 or may be executed by a remote or separate component, such as on a handheld device or a computer at a nurses' station. For example, the user interface 3402 may be implemented by the remote communicator 11 or the other monitoring clients 1, 4 of
The data management therapy component 3406 can communicate with one or more external data systems 3410. For example, the data management therapy component 3406 may compare the a patient's 3412 ID with electronic medical records 3410 to determine if the therapy entered (e.g., an infusion rate) via the user interface component 3402 is: (1) safe for the patient; (2) conforms with the patient's 3412 ailment, condition, disease, and/or therapy plan; (3) is not contraindicated by another medication or treatment; (4) and does not require the presence of a specialists not-determined to be within the proximity to the patient 3412 (as determined by an RFID tag, voice authentication, facial-recognition, username/pas sword identification or verification, secure signatures, or the like).
The data management therapy component 3406 may include all treatment settings, may verify settings with the external data systems 3410, and can log treatment history such as flow rates, drug settings, vital signs, etc. to the electronic medical records of the external data systems 3410. The data management therapy component 3406 may also set parameters for any safety monitors. If the data management therapy component 3406 confirms the treatment, the setting is sent to the pump engine component 3404.
The pump engine component sends 3404 sends the patient-treatment parameters, e.g., an infusion rate, to the infusion pump 3414. The infusion pump 3414 may be any infusion pump disclosed herein. In some embodiments of the present disclosure, the pump engine component 3404 only sends an infusion rate to the pump 3414. The pump may have fluid measurement capability that is redundant to a flow meter or is the primary fluid measurement of the system 3406.
The fluid measurement/safety monitor component 3408 may serve as a watchdog for the other pump engine component 3404, can receive flow data from a flow meter (not shown), and may serve as a watchdog for the pump 3414. The fluid measurement/safety monitor component 3408 can determine if a fault or error condition exists, e.g., the infusion rate as measured is outside of a predetermined range or is beyond a threshold, and can communicate a stop command to the pump 3414 to stop the pump 3414. Additionally or alternatively, the fluid measurement/safety monitor component 3408 can communicate to a mechanical occlusion device (not shown) to stop the flow of the infusion fluid to the patient 3412.
Additionally or alternatively, the fluid measurement/safety monitor component 3408 may receive feedback on flow rate as well as patient-condition parameters, e.g., heart rate, temperature, vital signs, etc. If any of the parameters monitored by the fluid measurement/safety monitor component 3408 are outside of a predetermined range, an alert, such as a text message or email, is issued, e.g., to a monitoring device, a remote communicator, other monitoring clients, a Smartphone, a tablet, a pc, a tablet computer, or the like. Additionally or alternatively, a mechanical fluid the fluid measurement/safety monitor component 3408 can communicate to a mechanical occlusion device (not shown) to stop the flow of the infusion fluid to the patient 3412.

The scanner 3928 of the hub 3910 may also read drug information and check it against the one or more servers 3926 for accuracy, and to ensure the drug is being delivered to the correct patient.
The hub 3910 may also include one or more components for execution by one or more processors therein. The hub 3910 may include a watchdog component for verifying at given intervals that a patient-care device is responding to communication queries (for example, a call and response challenge to each patient-care device every 5 seconds or other suitable interval, and if the hub 3910 receives no response, the hub 3910 “pulls” the safety line, i.e., indicates that an error condition exists), a watchdog circuit to monitor health and check voltage levels of various power supply voltages, a data integrity check to verify that the data being transmitted through the hub 3910 is not corrupted and checks internal and routed packets to be sent to the tablet 3914 or a patient-care device disclosed herein, and a range checker to allow for checking of programmed thresholds. The hub 3910 may use data integrity checking.
The hub 3910 can monitor the tablet 3914 and can separately alarm when an error occurs on a patient-care device. In some embodiments of the present disclosure, the hub 3910 may include all of the safety-critical circuitry and software such that the system 3900 is wholly fault-tolerant of the tablet's 3914 failures and/or is wholly fault-tolerant of any failure modes of the tablet 3514.
The hub 3910 may include an application programming interface (“API”) to display data on the display 3916 or the tablet 3914. The API may include a secure data class. A patient-care device can use the API to display on the display 3916 of the hub 3910. A patient-care device can send a message to the tablet 3914 instructing the tablet 3914 how to display an interface for the patient-care device. Additionally or alternatively, the hub 3910 sends a message to the tablet 3914 instructing the tablet 3914 to download an application from the one or more servers 3926 for displaying a user interface on the tablet 3914; the hub 3910 may send this message when a patient-care device is first connected to the hub 3910, either via a USB cable, or wirelessly (e.g., using pairing as described herein). Additionally or alternatively, the hub 3910 sends an instruction to the tablet 3914 for displaying a user interface for interfacing with the identified patient-care device.

Referring to the drawings,
The dock 6206 may aggregate data from the infusion pumps 6204A-6204D and pass the aggregated data to the tablet 6208. Each of the infusion pumps 6204A-6204D includes a respective display 6216A-6216D. The displays 6216A-6216D can be used for adjusting flow rates during infusion (predetermined safety criteria may be loaded while programming a prescription through the tablet 6208). An infusion can be started without the drug error reduction system's predetermined safety criteria by adjusting the flow rate from zero on a user interface displayed on the displays 6216A-6216D. The displays 6216A-6216D may also displays alerts and alarms both visually and with auditory indication.
The dock 6206 includes a power entry module, medical grade power supplies, and a backup battery. The dock 6206 also contains all of the communications hardware to interface to the tablet 6208 and to the medical IT systems, i.e., the one or more servers 6212. The dock 6206 may include hardware for traveling, such as a pole, and pole mounting hardware.
During programming of a prescription, the personalized drug error reduction system setting, e.g., predetermined safety criteria, is received directly from the one or more servers 6212. The tablet 6208 may be used to facilitate entering in a patient's ID and medication. Communication between the tablet 6208 and the one or more server 6212 may occur through the dock 6206. The predetermined safety criteria from the general drug error reduction system is cached on the dock 6206 or in one or more of the infusion pumps 6204A-6204D. In case the drug error reduction system is unavailable from the one or more servers 6212, the locally cached predetermined safety criteria from the drug error reduction system is updated through the network (e.g., WiFi) when it is available again.
The dock 6206 has enough battery to support 8 hours of operation of the hub dock 6206 and of the infusion pumps 6114A-6114D. The tablet 6110 may or may not have its own battery. In some embodiments, the infusion pumps 6204A-6204D may have enough battery (or other backup power) to support saving data when being pulled out of the dock 6206 and for alarming. This alarming capability and separate battery may also be moved to the dock 6206.
The pump's UI display on a display of the displays 6216A-6216D may be small. For example, in some embodiments, the displays 6216A-6216D may be just large enough so that only flow rate may be adjusted. This will allow an infusion to be started without entering in any other information. Since the patient's ID and/or drug name may be entered before accessing the EMR, there is limited data from a drug error reduction system or guardrails from the one or more servers 6212 if infusion is started without the tablet 6208. If the infusion is programmed with the tablet and then later the tablet is removed from the system the pump can continue to implement the guardrails feature related to the current prescription.
The device hub 6602 may have a physical or wireless connection to the tablet 6702. The device hub 6602 may include a cradle (not shown) for the tablet 6702. The tablet 6702 could optionally be rigidly attached to the device hub 6602.

The wall wart 6506 provides AC-to-DC conversion, and is coupled to the power module 6804 which contains the power entry module and an AC/DC power supply. The wall wart 6506 is optional and/or an AC-to-DC converted may be incorporated into the power module 6804. The power module 6804 may also include an extended battery to run multiple pump modules. The dock 6806 includes a back plane connecting together the various components.
The AC mains 6902 may be a direct connection to mains, such as through an AC outlet. The AC mains 6902 are coupled to a power entry and charging circuit 6910 which can rectify and convert the AC signal from the AC mains 6902 to a DC signal. The DC signal from the power entry AC/DC universal supply 6910 is fed into the DC power entry and charging circuit 6912.
The DC power 6904 receives DC power from a DC power source, such as the wall wart 6506 of
The wireless power 6906 may receive energy wirelessly. For example, the wireless power 6906 may include a coil that receives a time-varying magnetic field such that a voltage across the coil is induced; the induced AC signal is rectified and smoothed via a smoothing circuit and coupled to the DC power entry/charging circuit 6910.
The circuitry 6900 also includes a primary battery 6914, an external battery 6908, and a secondary battery 6920. The primary battery 6914 is used to supply power to one or more patient-care devices coupled to the patient-care device interface 6916 and a tablet (not shown) coupled to a tablet interface 6918. The interface 6916 may connect to none, one, or a plurality of patient-care devices through one or more communications technologies. The tablet interface 6918 may couple directly to a tablet or is coupled to a user interface of a tablet. The external battery connection 6908 may be electrical connectors (not explicitly shown) that are adapted for electrical coupling with one or more battery cells located in a separate housing of the electronic circuitry 6900. The external battery 6908 may supplement the primary battery 6914 or replace the primary battery 6914 in the event the primary battery 6914 fails. The secondary battery 6920 may be a super-capacitor 6920. In some embodiments, the secondary battery 6920 may be used only in failure modes where power is otherwise unavailable, e.g., the AC mains 6902 fails and the external battery 6908 is removed or fails. The secondary battery 6920 supplies sufficient power for a device processor subsystem 6922 to alarm via a secondary buzzer 6824.
The circuitry includes various power supplies, such as hub regulated power supplies 6926, a gated independent supply from regulated device power supplies 6928, and a tablet regulated power supply 6930.
The hub regulated power supplies 6926 is used to for powering the electric and sensors of the circuitry 6900. For example, the hub regulated power supplies 6926 are used to provide a voltage for an interface processor subsystem 6932.
The regulated device power supplies 6928 may be gated and may provide one or more independent and regulated voltage supplies that are sent to one or more patient-care devices coupled to the patient-care device interface 6916. The one or more regulated device power supplies 6928 that are sent to one or more patient-care devices via the patient-care device interface 6916 are monitored by a current sense 6934 and are enabled by the device processor subsystem 6922.

Additionally or alternatively, the tablet 14810 may instruct a caregiver, patient, or user how to resolve a source of a soft alarm and/or hard alarm.
A patient-care device, e.g., the infusion pump 14814, may include near-field communications (“NFC”) which communicates with the dock/hub 14812 when the infusion pump 14814 is in close proximity with the dock/hub 14812 to, for example, pair the devices, to pass configuration data, or set the infusion pump 14814 parameters for the patient with which the dock/hub 14812 is associated with. After the NFC communications, the infusion pump 14814 may communicate with the dock/hub 14812 wirelessly or via a wireless link. For example, an infusion pump 14814 may be in close (or contacting) proximity with the dock/hub 14812 in which NFC communications are used to pair the infusion pump 14814 with the dock/hub 14812 using a Bluetooth communications link.
The dock/hub 14812 may execute a device application 14820-14824 with a sandbox 14814. The sandbox 14814 may require the application to be written with predetermined criteria. In some embodiments, the sandbox 14814 may include an API having a secure data class. In yet additional embodiments, the sandbox 14814 may reside on the monitoring client 14810. The sandbox 14814 may be a virtual machine, may be a program that controls the resources (e.g., hardware or software resources available via an API, for example) the device applications 14820-14824 may utilize, may have global variables accessible by the device applications 14820-14824, and may be interpreter based. That is, the sandbox 14812 is a protected area that allows the device applications 14820-14824 to execute in a controlled and limited resource environment. The sandbox 14812 may be downloaded from the device manager 14808 or the application store 14806. The sandbox 14812 may be preconfigured for the particular dock/hub type, e.g., based upon any single or combination of a version number, a serial number, a lot number, a hardware version number, a software version number, an operating system type, an operating system service pack, other identifier, etc.
For example, the dock/hub may identify the infusion pump 14814 by serial number and download from the app store a device application 14850 into the dock/hub 14812 (e.g., the device app 14820). The device apps 14820-14824 may control and/or communicate with the infusion pump 14814 to relay information about the infusion pump 14814 to the tablet 14810 for display (e.g., via XML, for example). Additionally or alternatively, the one or more of the device apps 14820-14824 can display data from devices, use complex heuristics to combine data from several sources, etc. The sandbox 14818 may also control the access to various resources, such as: memory, non-volatile memory, hard drives, network interfaces, input devices, output devices, a buzzer, etc. In some embodiments, the sandbox 14818 may limit or prohibit the device applications 14820-14824 from reading and/or writing to specific files, such as system files. The sandbox 14818 may provide temporary and/or protected resources to the device applications 14820-14824, such as: a “scratchpad” memory space and/or a scratchpad harddisk space.
Any attempts by the device app 14820 to violate the DERS 14826, the local policies 14828, or inhibit the dock/hub 14828 to perform its primary functions (e.g., designated, high-priority functions) will be prevented by other software running on the dock/hub 14812 (e.g., an operating system such as the android operating system, IOs, Linux, Windows, or Windows CE that controls the execution of the sandbox via one or more process control blocks or one or more threads from a thread pool).
The sandbox 14818 may control the launching of one or more of the device apps 14820-14824. For example, the sandbox 14818 may check rules or links (e.g., dynamically linked library calls) to ensure that a device app of the device apps 14820-14824 designated for execution does not have any broken links and conforms to predetermined criteria controlled by the sandbox 14818. For example, the sandbox 14818 may check that all of the references from a device application 14850 to shared libraries within the dock/hub's 14812 software exist within specific “safe” shared libraries, the particular function or variable within the library exists, and the variable and data type requested by the device applications 14820-14824 or communicated by the device applications 14820-14824 conforms to or exists within the library.
In some embodiments of the present disclosure, the sandbox 14818 prioritizes access to resources. For example, if multiple device applications 14820-14824 request access to an alarm device (e.g., a speaker) or variable that indicates an alarm condition, the sandbox 14812 may prioritize the sources of the requests and display the prioritized list of alarm causes on the tablet 14810 allowing a caregiver to disable certain alarm conditions, address multiple alarm sources and/or assess the condition of the patient.

The one or more processors may be on the base and/or on the tablet. The operative set of processor-executable instructions may be stored in a non-transitory processor-readable memory, such as a random-access memory, a read-only memory, a disk memory, an EEPROM, an optical-based drive, or other memory. The memory may be in the base, in the tablet, and/or the base and the tablet may each have a respective memory and one or more respective processors. The one or more processors may be in operative communication with the memory to read the operative set of processor executable instructions from the memory. The flow chart diagram 20001 may be implemented as a method or a process. The one or more processors can execute the instructions to perform the method 20001 of
The one or more processors may be one or more of a microprocessor, a microcontroller, an assembly-based processor, a MIPS processor, a RISC processor, a CISC processor, a parallel or multi-core processor, a CPLD, a PLA, an FPGA, a virtual processor, the like, or some combination thereof.
Method 20001 can facilitate communications between a tablet and a base by using a wired connection to establish a wireless connection through a pairing protocol. For example, the tablet may be physically connected to the base through a USB cable which is used pair the two devices together to communicate using the Bluetooth protocol; after pairing, the devices can communicate with each other wirelessly using the Bluetooth protocol. The tablet may provide the user interface to the base. For example, an interface program running on the tablet may provide an interface to a hemodialisys apparatus to control and/or monitor a dialysis treatment of a patient or may provide an interface to an infusion pump to control and/or monitor the infusion pump during treatment of a patient.
In some embodiments, the wireless communications may be through one of Bluetooth LE, WiFi, Zigbee, λ-bee, ultra-wideband communication, wideband communication, code-division multiple access, time-division multiplexing, carrier-sense multiple-access multiplexing with or without collision avoidance, space-division multiplexing, frequency-division multiplexing, circuit-mode wireless multiplexing, wireless statistical multiplexing, orthogonal frequency-division multiplexing, or the like.
In some embodiments of the present disclosure, method 20001 includes acts 20002-20015. Act 20002 determines if a tablet is connected to a base through a physical connection. For example, a tablet may be connectable to a hemodialysis apparatus or to an infusion pump through a dock, a cable, a wire, a fiber optic link, or the like. The tablet and/or the base may determine that the tablet and the base are physically connected to each other through a USB connection, for example. The dock may provide a physical wired connection between the tablet and the base (e.g., a USB connection).
Act 20003 establishes a first communications link between the tablet and the base through the physical connection. For example, act 20003 may establish the appropriate software interfaces and/or may perform handshaking between the tablet and the base such that data may be communicated therebetween.
Act 20004 updates, if necessary, the interface program on the tablet through the first communications link. The update is necessary if the interface program is not the latest version, in which case the interface program needs to be updated. The update is also necessary, in some embodiments, if the interface program does not have all of the ready-for-release software patches and/or updates.
The base may be coupled to the internet (e.g., via WiFi or cellular service) such that the base may download and store the latest software for the tablet. In some embodiments, the base may include a list of version numbers which, during act 20004, the base notifies the tablet of the latest version number of software and the tablet downloads (e.g., via WiFi or cellular service) the latest version (e.g., through a WiFi or cellular service connection).
In yet an additional embodiment, the tablet determines that the software on the base is not the latest version; thereafter, the tablet downloads the latest version (e.g., via WiFi or cellular service) and communicates the latest version to the base so the base's software may be updated.
Act 20005 establishes a second communications link between the tablet and the base using the first communications link.
In act 20009, the base proceeds to operate. For example, the base may be an infusion pump and the tablet communicates a start command to the infusion pump. In another exemplary embodiment, a start button on the infusion pump may be pressed to commence treatment of a patient. In yet additional embodiments, the user is not required to commence operation and the infusion pump automatically starts to operate.
Act 20010 removes the physical connection between the tablet and the base. For example, a user may disconnect or undock the physical connection between the tablet and the base. Referring now to
When a link quality indicator that describes the quality of the wireless link between the tablet and the base falls below a predetermined threshold, the tablet or the base may enter into a headless state. In the headless state, the base continues to treat a patient and ignores communications from the tablet. When an alarm occurs, as long as the alarm is not a medical device stop-level alarm, the base will continue to operate.
In act 20013, the tablet and/or the base remain in the headless state as long as the link quality value remains below the threshold. Act 20014 determines if the link quality value returns above the predetermined threshold and act 20015 exits the headless state when the link quality value returns above the predetermined threshold. In some embodiments, once the tablet or the base enter into a headless state, a second link quality value greater than the first link quality value causes the tablet and/or the base exit the headless state.
Various alternatives and modifications can be devised by those skilled in the art without departing from the disclosure. Accordingly, the present disclosure is intended to embrace all such alternatives, modifications and variances. Additionally, while several embodiments of the present disclosure have been shown in the drawings and/or discussed herein, it is not intended that the disclosure be limited thereto, as it is intended that the disclosure be as broad in scope as the art will allow and that the specification be read likewise. Therefore, the above description should not be construed as limiting, but merely as exemplifications of particular embodiments. And, those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto. Other elements, steps, methods and techniques that are insubstantially different from those described above and/or in the appended claims are also intended to be within the scope of the disclosure.
The embodiments shown in drawings are presented only to demonstrate certain examples of the disclosure. And, the drawings described are only illustrative and are non-limiting. In the drawings, for illustrative purposes, the size of some of the elements may be exaggerated and not drawn to a particular scale. Additionally, elements shown within the drawings that have the same numbers may be identical elements or may be similar elements, depending on the context.
Where the term “comprising” is used in the present description and claims, it does not exclude other elements or steps. Where an indefinite or definite article is used when referring to a singular noun, e.g. “a” “an” or “the”, this includes a plural of that noun unless something otherwise is specifically stated. Hence, the term “comprising” should not be interpreted as being restricted to the items listed thereafter; it does not exclude other elements or steps, and so the scope of the expression “a device comprising items A and B” should not be limited to devices consisting only of components A and B. This expression signifies that, with respect to the present disclosure, the only relevant components of the device are A and B.
Furthermore, the terms “first,” “second,” “third,” and the like, whether used in the description or in the claims, are provided for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances (unless clearly disclosed otherwise) and that the embodiments of the disclosure described herein are capable of operation in other sequences and/or arrangements than are described or illustrated herein.
