Embodiments of the present invention relate generally to the storage and dispensing of medication and supplies proximate a patient for whom the medication or supplies are intended. In particular, embodiments may provide a method and apparatus for receiving medications or supplies and controlling access to the contents.
Medication dispensing in healthcare facilities can be a complex and time consuming process. In order for patients to have their medications and supplies when they are required, an authorized medical person may have to retrieve the medication or supplies and deliver them to the patient. The authorized medical person may also have to administer the medication or configure the supplies for use as necessary.
“Titratables,” or intravenous titratable medications, also referred to as “drips,” rarely run on a prescribed schedule such that it may be difficult to estimate when a patient may need an intravenous medication. Having authorized healthcare personnel check on a patient's medication status, check a patient's prescribed medication status, request medication from a central pharmacy, and retrieve a medication from a central pharmacy can be very time consuming and may significantly impact the efficiency of healthcare personnel. Further, quality of care may be reduced by inefficient practices if healthcare personnel are preoccupied with requesting and obtaining medications for a patient rather than administering them and speaking with a patient. As such, it may be desirable to improve the efficiency with which medications are dispensed to a patient, particularly intravenous medications.
Embodiments of the present invention may provide various apparatuses, systems, and methods for improving the efficiency of medication distribution within a healthcare facility. In particular, embodiments may provide for storing and dispensing medications to an authorized medical person for administration to a patient in a healthcare facility.
An apparatus according to an example embodiment of the present invention may include a housing defining a cavity, a door, two or more receivers disposed within the cavity, a lock configured to lock the door in the closed position, and a user interface configured to receive a request from a user. The door may be configured to be movable between an open position and a closed position relative to the housing, where in the open position; the cavity of the housing is accessible. Each receiver may be configured to hold an article for a patient, where each of the receivers may be movable between an accessible position in which the contents of the receiver are accessible, and an inaccessible position in which the contents of the receiver are inaccessible. The request from the user may identify the contents of one of the receivers. In response to the request received at the user interface, the door may be configured to be unlocked. The receiver including the contents identified by the request may be configured to be moved to the accessible position in response to the door being moved to the open position. The one or more receivers not including the contents identified by the request may be configured to remain in the inaccessible position.
According to some embodiments, the receiver including the contents identified by the request may be engaged by the door, and the receiver including the contents identified by the request is moved to the accessible position as the door is moved to the open position. The user interface may be configured to receive a restock request to access each of the two or more receivers disposed within the cavity, and in response to the restock request to access each of the two or more receivers, each of the receivers may be configured to move to the accessible position in response to the door moving to the open position.
An apparatus according to some example embodiments may include two or more windows in the door, where each of the two or more windows corresponds to one of the two or more receivers disposed within the cavity, and where the presence of the contents of each of the receivers may be visible through a respective window. Embodiments may include a photovoltaic panel disposed on the housing configured to charge a battery disposed within the housing. The user interface and the lock may be configured to be powered by the battery. The housing may optionally include a cooling pack receiver configured to receive a cooling pack therein. The housing may optionally include one or more ducts from the cooling pack receiver to a respective one or more of the two or more receivers for directing cooling air to one or more of the receivers.
Embodiments of an apparatus according to the present invention may further include a cooling pack configured to be received into a cooling pack receiver of the housing, where the cooling pack includes a passive, cold body and a powered fan configured to move air across the cold body and into the cavity of the housing. Embodiments may include a reader configured to read identifying indicia of an article to be received within a receiver of the apparatus. The reader may be configured to read identifying indicia of an article removed from a receiver of the apparatus. The apparatus may be configured to compare the identifying indicia of the article removed from a receiver of the apparatus to the request received at the user interface. The apparatus may be configured to provide an alert in response to the identifying indicia of the article matching the identity of an article of the request received at the user interface, where the notification includes at least one of an audible alert or a visual alert.
Embodiments of the present invention may include a method for improving the efficiency of storage and dispensing of articles such as medication in a healthcare facility. An example method may include receiving, at a housing, two or more articles where each article is received within a receiver within a cavity of the housing, where the articles are each received within a receiver arranged in an accessible position through a door arranged in an open position. Method may include securing the two or more articles in the housing, where securing may include arranging the receivers in an inaccessible position and locking the door in a closed position. Methods may further include receiving a request at a user interface of the housing for one of the two or more articles received within the housing, providing for unlocking of the door, and providing for release of the receiver including the requested article, where in response to the door being moved to the open position, the receiver including the requested article is moved to the accessible position. Methods may also include maintaining the receivers that do not contain the requested article in an inaccessible position.
According to some embodiments, receiving the two or more articles may include reading identifying indicia of each of the two or more articles and receiving a respective receiver identifier for the receiver into which each of the two or more articles are received. In response to receiving a request at a user interface for one of the articles, the method may provide for release of the receiver including the receiver identifier that corresponds to the one of the articles requested.
Methods of example embodiments may optionally include receiving an identifier of an article removed from the receiver including the requested article; comparing the identifier of the article removed to the one of the two or more articles requested, and providing a notification in response to the identifier of the article removed matching the one of the two or more articles requested. The notification may include at least one of an audible alert or a visual alert. Methods may include providing for cooling of at least one of the receivers in the cavity of the housing.

Reference now will be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Embodiments of the present invention may provide various apparatuses, systems, and methods for improving the efficiency of medication distribution within a healthcare facility. Some embodiments and components of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, various embodiments of the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements.
A technician or other authorized medical person may be required to deliver medications throughout a healthcare facility. Such a person is referred to herein generally as a technician. As the technician may be responsible for a large number of medications for a large number of patients, the distribution of the medications may take a considerable amount of time, and the arrival time of the technician at any particular patient's room may be uncertain. As such, medication may be delivered to patients throughout the facility ahead of the anticipated need. For example, the medications needed for all patients in a particular unit of a healthcare facility may all be delivered together maximizing distribution efficiency; however, the medications may not be ready to be administered upon arrival at the unit. It may be undesirable to store medication in a patient room awaiting administration as the medication may be tampered with, taken from the patient room, or otherwise misused. Therefore, secure storage of the medication may be desirable. However, secure storage at the nurse station may be inconvenient and may lead to additional inefficiencies of medication administration.
Embodiments of the present invention may be used for storage and distribution, and control of access to articles, such as intravenous bags within a healthcare facility. Embodiments may be implemented in any environment in which it is desirable to store, monitor access, control access, and dispense articles from a storage location. However, embodiments of the present invention are herein described with respect to healthcare facilities, such as hospitals, physicians' offices, healthcare clinics, and any other facility that manages and/or stores intravenous bags.
Embodiments of the present invention may be configured to provide secure, temporary storage of medications proximate a patient in a healthcare facility. The storage and dispensing system may provide easy and efficient access to medications for a patient, particularly medications and supplies for which timing may not be easily predicted, such as intravenous titratables or drip medications, as generally administered from intravenous bags. Embodiments may enable efficient, secure stocking of the storage unit while providing a secure dispensing method using medication and user authentication mechanisms to ensure accurate medication dispensing. Example embodiments may include a compact form factor which may be implemented in existing healthcare facilities and some embodiments may include power supplies, such as a battery, in the storage housing enabling installation without a hardwired infrastructure.
The storage and dispensing system housing 110 may include a user interface 130 and a scanner 150, as will be described further below. In addition to a primary door 120, some example embodiments may include secondary doors 170 as shown in
In practice, a technician may retrieve medications to be distributed throughout a healthcare facility, or to a unit of a healthcare facility. The medications may be retrieved from a central pharmacy as will be further detailed in an example below. The technician may deliver medications to patients' rooms using a cart or other means for transporting the medications. The medications for a particular patient's room or group of patients' rooms may be stored in bins or other containers to enable the technician to readily identify the medications for a particular room or group of rooms.
Upon arrival at a storage and dispensing system of example embodiments, such as the system illustrated in
According to example embodiments, as will be described further below, the bins 220 may be individually retained within the cavity 125 of the housing 110. Access to a bin 220 may be provided by unlocking of the door 120 and release of the bin 220 to be accessed, such that the bin 220 moves together with the door. As the door 120 moves to the open position (shown in
In order to load medication into the receivers or bins 220 of the system 100, a technician may scan the identification of a medication to be loaded using scanner 150 as shown in
The technician may load medications to the system as needed for one or more patients. In some cases, the technician may be required to remove medications from the system, such as in the case of a discharged patient, a change in a patient's medication orders, the recall of a medication, or the expiration of a medication. In such an embodiment, the removed medication may be scanned by the scanner 150 to identify the medication such that the system acknowledges the removal of the medication by the technician. As the technician provided identification to access the system 100, an audit record may be stored of access to the system and the insertion and/or removal of medications. The audit record of access to a storage and dispensing system may be used for future audits of the handling of certain medications or to enable traceability of medications and their transport throughout a facility.
In some example embodiments, the scanned identifying indicia of a medication may include an expiration date, lot number, and/or refrigeration requirements of the medication. The system may be configured to monitor such medications such that upon expiration of a medication, recall of a lot of medication, or failure to meet the refrigeration requirements of a medication, the medication may be flagged for removal by a technician, and dispensing of the medication to an authorized medical person requesting the medication for administration may be prevented.
Once the technician has properly identified and loaded medications into the bins 220, the technician may close the door 120, thereby moving each of the bins 220 to an inaccessible position. The door 120 may be locked upon closure, and the contents of the system (i.e., the medications stored therein) are inaccessible and secure.
When a patient is in need of a medication, and an authorized medical person is available to dispense and administer the medication, the authorized medical person may engage the storage and dispensing system 100. The system may be conveniently located proximate the patient such that the authorized medical person does not have to walk very far to retrieve the necessary medication. According to some example embodiments, the storage and dispensing system 100 may be located in the room of the patient. The authorized medical person may identify themselves to the system 100 by interaction with the user interface 130 and/or the scanner 150. As with the identification of the technician, the system may perform a biometric scan at the user interface 130 to identify the authorized medical person, scan identification credentials at the scanner 150, receive a PIN at the user interface 130, or any combination of identification methods.
Upon identification and confirmation by the system 100 of the authorized medical person, the user interface may provide options for available medications to be retrieved. In some embodiments of the present invention, the system 100 may be configured to serve multiple patients such that an authorized medical person may select the patient via the user interface 130 for whom they are retrieving medication. Systems of example embodiments may also be configured to store medications for a plurality of time periods (e.g., morning, afternoon, evening) or various types of medications for a specific patient. As such, the authorized medical person may select the medication type and/or time period for which the requested medication is intended. Provided the authorized medical person is authorized to access the requested medication, the door 120 may be unlocked. Access to some or all of the bins or the door 120 may be precluded if the person attempting to access the medications is not authorized to access some or all of the medications stored therein or to administer medications to a particular patient.
While example embodiments above have been described with respect to bins 260, 270 accessed through the door 120,
Storage of medications proximate a patient may increase the efficiency of medication distribution as outlined above; however, some medications may require refrigeration in order to maintain their effectiveness. As such, example embodiments of the present invention may be configured with a mechanism for cooling the contents of the system.
According to some example embodiments, the cooling pack receiver 310 may not include specific ducts, but instead a cooling pack 300 received within the cooling pack receiver 310 may cool all of the contents of the system. In still other embodiments, the cooling pack receiver may be configured such that a specific bin of the system is configured to be a refrigerated bin, while other bins may not be able to be cooled by the cooling pack. In such an embodiment, the cooling pack receiver 310 may be in fluid communication with only the bin configured to be cooled.
The cooling pack 300 of example embodiments may further include a powered fan module 350 which may be attached to the cold body 340. The powered fan module may include a battery configured to power a fan disposed therein to force air through the cooling body and out through vents 360, providing a cooled air stream through the vents 360 to at least a portion of the cavity of the system. The fan module may be detached from the cold body such that the fan module may be recharged while the cold body is cooled. When a cooling pack is needed, a technician may remove the cold body 340 from the cold storage (e.g., a freezer), remove a fan module 350 from the charger, and join the two together. When the cooling pack 300 is turned on or inserted into a cooling pack receiver 310 of a housing 320, the fan may run, forcing the cooling air over the pellet membranes and into the cavity of the housing 320.
In some example embodiments, the cooling pack may be used to provide power to the storage and dispensing system. For example, when medications are loaded into a housing 320, a cooling pack 300 may also be loaded in. The cooling pack 300 may include a battery of sufficient power to provide cooling (if necessary) and to power the user interface and lock mechanisms of the storage and dispensing system. In such an embodiment, the battery of the cooling pack may be charged as described above, and replaced within the housing 320 each time a technician loads medication into the housing.
In other example embodiments, the cooling pack may not require a powered fan to facilitate cooling of the contents of the housing 320, but may rely on convection to cool the medications within the housing. Optionally, the housing may include a fan to drive air flow over a non-powered cooling pack in order to actively cool the contents of the housing.
Described herein is an example embodiment of a method of distributing medications to storage and dispensing systems of example embodiments of the present invention in a healthcare facility. A technician or a central pharmacy distribution center may receive medication orders for a plurality of patients. The orders may include patient names, medications, doses, quantities, etc. In one example embodiment, the technician may retrieve the medications for the order, retrieve a printed label for the medication, and place the label on the medication. Optionally, an automated system may prepare medications to fill the medication order by retrieving and labeling the medication appropriately using an automated, or semi-automated process. The appropriately labeled medication may then be loaded to a cart for transport to the appropriate location in the healthcare facility. A medication label may be scanned prior to loading into a cart, for example, a cart may include a user interface which includes a scanner for reading identifying indicia from the medication. Upon scanning of the medication, it may be loaded to the cart. The user interface of the cart may provide an indication of the location on the cart where the medication should be placed. The location may be proximate other medications that are intended to be distributed to the same, or similar locations.
The scanning and loading of medication may continue until all of the medications for a facility or unit of a facility are loaded to the cart. Optionally, scanning and loading may continue until the cart has reached capacity. During the scanning of medication, the user interface of the cart may indicate that one or more of the scanned medications requires refrigeration. The user interface may indicate to the technician that one or more cooling packs will be required for distribution with the medications. Upon retrieving the cooling packs and loading them onto the cart, the cart may be ready to be used to distribute the medications stored therein. As the cart may hold medications only for a short time (e.g., during delivery), the medications may not require refrigeration. However, one or more locations on the cart may be refrigerated or cooled for the storage of medications. Cooling may be performed by a cooling pack of example embodiments.
During distribution, a technician may move the cart throughout a healthcare facility. Upon arrival at a healthcare facility unit, the technician may encounter a storage and dispensing system of example embodiments of the present invention. The technician may scan or otherwise indicate to the user interface of the cart the identification of the storage and dispensing system they are near. The user interface may provide an indication of the medications needed for distribution to the system and may provide the locations on the cart where the medications may be found. The user interface may also indicate whether a cooling pack is needed for the storage and dispensing system housing. As outlined above, the technician may identify themselves to the system through the scanner (e.g., scanner 150 of
Example embodiments of the present invention may be configured to provide an audit trail of medication from the central pharmacy to the patient. As outlined above, each movement of the medication may be identified by a scanning operation, and each movement or scanning operation may be associated with an authorized medical person. In this manner, medications, particularly controlled substances, may be monitored throughout a healthcare facility and the responsible medical person may also be identified. Such control may ensure compliance with applicable legal requirements for handling medications in a facility and may provide records of medication transactions that can be monitored and reviewed as required.
Systems of example embodiments may include wireless communications with one or more networks of the healthcare facility. The system may interface with a network of a healthcare facility to ensure accurate dispensing of medication to authorized personnel. Changes in medication orders, patient status, and other information may be communicated via the network to ensure proper medication distribution from the system.
The transfer of data and information between a storage and dispensing system of example embodiments and a healthcare facility network may be implemented in various embodiments of the present invention. As used herein, where a computing device is described herein to receive data from another computing device, such as receiving an indication of medication requested at the user interface, it will be appreciated that the data may be received directly from the another computing device and/or may be received indirectly via one or more intermediary computing devices, such as, for example, one or more servers, relays, routers, network access points, and/or the like. Similarly, where a computing device is described herein to send data to another computing device, it will be appreciated that the data may be sent directly to the another computing device or may be sent to the another computing device via one or more interlinking computing devices, such as, for example, one or more servers, relays, routers, network access points, and/or the like.
In some example embodiments, processes and steps of the invention may be carried out by computing devices that may be in communication with a network, such as an information network of a healthcare facility. The computing devices may include storage and dispensing systems, nurse carts, technician carts, portable communications stations, or the like.

Thus, for example, when the processor is embodied as an ASIC, FPGA, or the like, the processor may be specifically configured hardware for conducting the operations described herein. Alternatively, as another example, when the processor is embodied as an executor of software instructions, the instructions may specifically configure the processor to perform one or more operations described herein.
In some example embodiments, the memory 410 may include one or more non-transitory memory devices such as, for example, volatile and/or non-volatile memory that may be either fixed or removable. In this regard, the memory 410 may comprise a non-transitory computer-readable storage medium. It will be appreciated that while the memory 410 is illustrated as a single memory, the memory may comprise a plurality of memories. The plurality of memories may be embodied on a single computing device or may be distributed across a plurality of computing. The memory may be configured to store information, data, applications, instructions and/or the like for enabling embodiments of the present invention to carry out various functions in accordance with one or more example embodiments. For example, the memory may be configured to buffer input data for processing by the processor. Additionally or alternatively, the memory may be configured to store instructions for execution by the processor. As yet another alternative, the memory may include one or more databases that may store a variety of files, contents, or data sets. Among the contents of the memory, applications may be stored for execution by the processor to carry out the functionality associated with each respective application.
A user interface 420 of example embodiments, such as the user interface of a dispensing system, may be in communication with the processing circuitry to receive an indication of a user input at the user interface and/or to provide an audible, visual, mechanical, or other output to the user. As such, the user interface may include, for example, a user input interface 420 such as a keyboard, a mouse, a joystick, a display, a touch screen display, a microphone, a speaker, and/or other input/output mechanisms. As such, the user interface may 420, in some example embodiments, provide means for user control of embodiments of the present invention. In some example embodiments in which the invention is embodied as a server, cloud computing system, or the like, aspects of user interface may be limited or the user interface may not be present. In some example embodiments, one or more aspects of the user interface may be implemented on a user terminal. Accordingly, regardless of implementation, the user interface may provide input and output means to facilitate handling, storing, transporting, or dispensing of medication in accordance with one or more example embodiments.
The communication interface 430 may include one or more interface mechanisms for enabling communication with other devices and/or networks. In some cases, the communication interface may be any means such as a device or circuitry embodied in either hardware, or a combination of hardware and software that is configured to receive and/or transmit data from/to a network and/or any other device or module in communication with the processing circuitry.
