The present disclosure relates generally to aggregating and analyzing drug administration data.
Pharmaceutical products (including large and small molecule pharmaceuticals, hereinafter “drugs”) are administered to patients in a variety of different ways for the treatment of specific medical indications. Regardless of the manner of the administration, care must be taken when administering drugs to avoid adverse effects on the patient. For example, care must be taken not to administer more than a safe amount of the drug to the patient. This requires consideration of the amount of dose given and the time frame over which the dose is delivered, sometimes in relation to previous doses, or doses of other drugs. Moreover, care must be taken not to inadvertently administer an incorrect drug to the patient, or drugs that have degraded due to their age or storage conditions. All of these considerations can be conveyed in guidance associated with the specific drugs or drug combinations. However, this guidance is not always followed correctly, for example due to mistakes, such as human error. This can lead to adverse effects on the patient or result in inappropriate drug administration, for example insufficient or excessive volume of drug being administered for the specific medical indication.
Patients rarely share the same medical characteristics. For example, patients generally have different ages, weights, general states of health, and medical histories. Therefore the same illness tends to affect patients differently. Thus, while guidance supplied with specific drugs may aid a medical practitioner or patient in determining a suitable dosage amount, dosage frequency, and dosage time (dosage regimen) it will not necessarily inform the medical practitioner or patient of the optimum dosage for a particular patient. In order to determine the optimum dosage, the medical practitioner or patient would have to measure some or all possible factors affecting a patient and consider how the different factors interact. This is often impossible, and so medical practitioners or patients have to make a best guess as to the optimum dosage based on information that they have observed about the patient. These best guesses will rarely result in timely administration of an optimum dosage. Moreover, because the best guess is based on data observed by the medical practitioner or patient, there is an undesirable element of subjectivity and possibility of user error when determining or attempting to administer the best guess dosage.
In relation to how a drug is administered to the patient, there are various dosage forms that can be used. For example, these dosage forms may include parenteral, inhalational, oral, ophthalmic, topical, and suppository forms of one or more drugs.
The dosage forms can be administered directly to the patient via a drug administration device. There are a number of different types of drug administration devices commonly available for delivery of the various dosage forms including: syringes, injection devices (e.g., autoinjectors, jet injectors, and infusion pumps), and inhalers.
In general, systems and methods for aggregating and analyzing drug administration data are provided.

The present invention is described by way of reference to the accompanying figures which are as follows:
Certain exemplary embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices, systems, and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. A person skilled in the art will understand that the devices, systems, and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one exemplary embodiment may be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.
Further, in the present disclosure, like-named components of the embodiments generally have similar features, and thus within a particular embodiment each feature of each like-named component is not necessarily fully elaborated upon. Additionally, to the extent that linear or circular dimensions are used in the description of the disclosed systems, devices, and methods, such dimensions are not intended to limit the types of shapes that can be used in conjunction with such systems, devices, and methods. A person skilled in the art will recognize that an equivalent to such linear and circular dimensions can easily be determined for any geometric shape. A person skilled in the art will appreciate that a dimension may not be a precise value but nevertheless be considered to be at about that value due to any number of factors such as manufacturing tolerances and sensitivity of measurement equipment. Sizes and shapes of the systems and devices, and the components thereof, can depend at least on the size and shape of components with which the systems and devices will be used.
Examples of various types of drug administration devices, namely: an autoinjector 100, an infusion pump 200, and an inhaler 300, are described below.
Autoinjectors
The autoinjector 100 includes a housing 130 which contains the drug holder 110, the drive element 124, and the drive mechanism 126 within the body of the housing 130, as well as containing the discharge nozzle 122, which, prior to injection, would typically be contained fully within the housing 130, but which would extend out of the housing 130 during an injection sequence to deliver the drug. The dispensing mechanism 120 is arranged so that the drive element 124 is advanced through the drug holder 110 in order to dispense the drug through the discharge nozzle 122, thereby allowing the autoinjector 100 to administer a drug retained in drug holder 110 to a patient. In some instances, a user may advance the drive element 124 through the drug holder 110 manually. In other instances, the drive element 124 may be advanced through the drug holder 110 under control of a robotic surgical system. In other instances, the drive mechanism 126 may include a stored energy source 127 which advances the drive element 124 without user assistance. The stored energy source 127 may include a resilient biasing member such as a spring, or a pressurized gas, or electronically powered motor and/or gearbox.
The autoinjector 100 includes a dispensing mechanism protection mechanism 140. The dispensing mechanism protection mechanism 140 typically has two functions. Firstly, the dispensing mechanism protection mechanism 140 can function to prevent access to the discharge nozzle 122 prior to and after injection. Secondly, the autoinjector 100 can function, such that when put into an activated state, e.g., the dispensing mechanism protection mechanism 140 is moved to an unlocked position, the dispensing mechanism 120 can be activated.
The protection mechanism 140 covers at least a part of the discharge nozzle 122 when the drug holder 110 is in its retracted position proximally within the housing 130. This is to impede contact between the discharge nozzle 122 and a user. Alternatively, or in addition, the protection mechanism 140 is itself configured to retract proximally to expose the discharge nozzle 122 so that it can be brought into contact with a patient. The protection mechanism 140 includes a shield member 141 and return spring 142. The return spring 142 acts to extend the shield member 141 from the housing 130, thereby covering the discharge nozzle 122 when no force is applied to the distal end of the protection mechanism 140. If a user applies a force to the shield member 141 against the action of the return spring 142 to overcome the bias of the return spring 142 (or a robotic surgical system causes such a force to be provided to the shield member 141), the shield member 141 retracts within the housing 130, thereby exposing the discharge nozzle 122. The protection mechanism 140 may alternatively, or in addition, include an extension mechanism (not shown) for extending the discharge nozzle 122 beyond the housing 130, and may further include a retracting mechanism (not shown) for retracting the discharge nozzle 122 within the housing 130. The protection mechanism 140 may alternatively, or in addition, include a housing cap and/or discharge nozzle boot, which can be attached to the autoinjector 100. Removal of the housing cap would typically also remove the discharge nozzle boot from the discharge nozzle 122.
The autoinjector 100 also includes a trigger 150. The trigger 150 includes a trigger button 151 which is located on an external surface of the housing 130 so that it is accessible by a user of the autoinjector 100 and/or by a robotic surgical system configured to control actuation of the trigger 150. When the trigger 150 is pressed by a user (or a robotic surgical system causes the trigger 150 to be pressed), it acts to release the drive mechanism 126 so that, via the drive element 124, the drug is then driven out of the drug holder 110 via the discharge nozzle 122.
The trigger 150 can also cooperate with the shield member 141 in such a way that the trigger 150 is prevented from being activated until the shield member 141 has been retracted proximally sufficiently into the housing 130 into an unlocked position, for example by pushing a distal end of the shield member 141 against the skin of a patient. When this has been done, the trigger 150 becomes unlocked, and the autoinjector 100 is activated such that the trigger 150 can be depressed and the injection and/or drug delivery sequence is then initiated. Alternatively, retraction of the shield member 141 alone in a proximal direction into the housing 130 can act to activate the drive mechanism 126 and initiate the injection and/or drug delivery sequence. In this way, the autoinjector 100 has device operation prevention mechanism which prevents dispensing of the drug by, for example, preventing accidental release of the dispensing mechanism 120 and/or accidental actuation of the trigger 150.
While the foregoing description relates to one example of an autoinjector, this example is presented purely for illustration, the present invention is not limited solely to such an autoinjector. A person skilled in the art understands that various modifications to the described autoinjector can be implemented within the scope of the present disclosure.
Autoinjectors of the present disclosure can be used to administer any of a variety of drugs, such as any of epinephrine, Rebif, Enbrel, Aranesp, atropine, pralidoxime chloride, and diazepam.
Infusion Pumps
Patients can require precise, continuous delivery of medication or medication delivery on a regular or frequent basis at set periodic intervals. Infusion pumps can provide such controlled drug infusion by facilitating the administering of the drug at a precise rate that keeps the drug concentration within a therapeutic margin, without requiring frequent attention by a healthcare professional or the patient.
Infusion pumps of the present disclosure can be used to administer any of a variety of drugs, such as any of insulin, antropine sulfate, avibactam sodium, bendamustine hydrochloride, carboplatin, daptomycin, epinephrine, levetiracetam, oxaliplatin, paclitaxel, pantoprazole sodium, treprostinil, vasopressin, voriconazole, and zoledronic acid.
The infusion pump 200 further includes control circuitry, for example a processor 296 in addition to a memory 297 and a user interface 280, which together provide a triggering mechanism and/or dosage selector for the pump 200. The user interface 280 can be implemented by a display screen located on the housing 230 of the infusion pump 200. The control circuitry and user interface 280 can be located within the housing 230 or external thereto and can communicate via a wired or wireless interface with the pump 216 to control its operation.
Actuation of the pump 216 is controlled by the processor 296, which is in communication with the pump 216 for controlling the pump's operation. The processor 296 can be programmed by a user (e.g., patient or healthcare professional) via a user interface 280 and/or can be programmed electronically using a computer system (e.g., using a robotic surgical system configured to control operation of the pump 216). This enables the infusion pump 200 to deliver the drug to a patient in a controlled manner. The user (or computer system) can enter parameters, such as infusion duration and delivery rate. The delivery rate can be set to a constant infusion rate or as set intervals for periodic delivery, typically within pre-programmed limits. The programmed parameters for controlling the pump 216 are stored in and retrieved from the memory 297 which is in communication with the processor 296. The user interface 280 can take the form of a touch screen or a keypad.
A power supply 295 provides power to the pump 216 and can take the form of an energy source which is integral to the pump 216 and/or a mechanism for connecting the pump 216 to an external source of power.
The infusion pump 200 can take on a variety of different physical forms depending on its designated use. It can be a stationary, non-portable device, e.g., for use at a patient's bedside, in an operating room, etc., or it can be an ambulatory infusion pump which is designed to be portable or wearable. An integral power supply 295 is particularly beneficial for ambulatory infusion pumps.
While the foregoing description relates to one example of an infusion pump, this example is provided purely for illustration. The present disclosure is not limited to such an infusion pump. A person skilled in the art understands that various modifications to the described infusion pump can be implemented within the scope of the present disclosure. For example, the processor may be pre-programmed, such that it is not necessary for the infusion pump to include a user interface.
Inhalers
The drug holder 310 is removably held within a housing 330 of the inhaler 300. A passage 333 formed in the housing 330 connects a first opening 331 in the housing 330 and a second opening 332 in the housing 330. The drug holder 310 is received within the passage 333. The drug holder 310 is slidably insertable through the first opening 331 of the housing 330 into the passage 333. The second opening 332 of the housing 330 forms a mouthpiece 322 configured to be placed in a patient's mouth or a nosepiece configured to be placed in a patient's nostril, or a mask configured to be placed over the patient's mouth and nose. The drug holder 310, the first opening 331 and the passage 333 are sized such that air can flow through the passage 333, around the drug holder 310, between the first opening 331 and the second opening 332. The inhaler 300 can be provided with a dispensing mechanism protection mechanism 140 in the form of a cap (not shown) which can be fitted to the mouthpiece 322.
Inhaler 300 further includes a trigger 350 including a valve actuation feature 355 configured to actuate the valve 325 when the trigger 350 is activated. The valve actuation feature 355 is a projection of the housing 330 into the passage 333. The drug holder 310 is slidably movable within the passage 333 from a first position into a second position. In the first position, an end of the movable element 326 in the resting position abuts the valve actuation feature 355. In the second position, the drug holder 310 can be displaced towards the valve actuation feature 355 such that the valve actuation feature 355 moves the movable element 326 into the drug holder 310 to actuate the valve 325 into the open state. The user's hand (or other element handheld by a user or controlled by a robotic surgical system) provides the necessary force to move the drug holder 310 from the first position to the second position against the resiliently biased movable element 326. The valve actuation feature 355 includes an inlet 356, which is connected to the nozzle 321. The inlet 356 of the valve actuation feature 355 is sized and positioned to couple to the opening 324 of the valve 325 such that the ejected mist of droplets and/or gas cloud can enter the inlet 356 and exit from the nozzle 321 into the passage 333. The nozzle 321 assists in the atomization of the bulk liquid into the mist of droplets and/or gas cloud.
The valve 325 provides a metering mechanism 370. The metering mechanism 370 is configured to close the valve after a measured amount of liquid, and therefore, drug, has passed through the opening 324. This allows a controlled dose to be administered to the patient. Typically, the measured amount of liquid is pre-set, however, the inhaler 300 can be equipped with a dosage selector 360 that is operable by a user and/or electronically by a computer system to change the defined amount of liquid.
While the foregoing description relates to one particular example of an inhaler, this example is purely illustrative. The description should not be seen as limited only to such an inhaler. A person skilled in the art understands that numerous other types of inhalers and nebulizers may be used with the present disclosure. For example, the drug can be in a powdered form, the drug can be in liquid form, or the drug can be atomized by other forms of dispensing mechanism 320 including ultrasonic vibration, compressed gas, a vibrating mesh, or a heat source.
The inhalers of the present disclosure can be used to administer any of a variety of drugs, such as any of mometasone, fluticasone, ciclesonide, budesonide, beclomethasone, vilanterol, salmeterol, formoterol, umeclidinium, glycopyrrolate, tiotropium, aclidinium, indacaterol, salmeterol, and olodaterol.
Drug Administration Devices
As will be appreciated from the foregoing, various components of drug delivery devices are common to all such devices. These components form the essential components of a universal drug administration device. A drug administration device delivers a drug to a patient, where the drug is provided in a defined dosage form within the drug administration device.
As shown in
The device 500 is provided with a triggering mechanism 50 for initiating the release of the drug from the drug holder 10 by the dispensing mechanism 20. The device 500 includes the feature of a metering/dosing mechanism 70 which measures out a set dose to be released from the drug holder 10 via the dispensing mechanism 20. In this manner, the drug administration device 500 can provide a known dose of determined size. The device 500 includes a dosage selector 60 which enables a user to set the dose volume of drug to be measured out by the metering mechanism 50. The dose volume can be set to one specific value of a plurality of predefined discrete dose volumes, or any value of predefined dose volume within a range of dose volumes.
The device 500 includes a device operation prevention mechanism 40 or 25 which when in a locked state will prevent and/or stop the dispensing mechanism 20 from releasing the drug out of the drug holder 10, and when in an unlocked state will permit the dispensing mechanism 20 to release the drug dosage from out of the drug holder 10. This can prevent accidental administration of the drug, for example to prevent dosing at an incorrect time, or for preventing inadvertent actuation. The device 500 also includes a dispensing mechanism protection mechanism 42 which prevents access to at least a part of the dispensing mechanism 20, for example for safety reasons. The device operation prevention mechanism 40 and the dispensing mechanism protection mechanism 42 can be the same component.
The device 500 includes a device indicator 85 which is configured to present information about the status of the drug administration device and/or the drug contained therein. The device indicator 85 can be a visual indicator, such as a display screen, or an audio indicator. The device 500 includes a user interface 80 which can be configured to present a user of the device 500 with information about the device 500 and/or to enable the user to control the device 500. The device 500 includes a device sensor 92 which is configured to sense information relating to the drug administration device and/or the drug contained therein, for example dosage form and device parameters. As an example, in embodiments which include a metering mechanism 70 and a dosage selector 60, the embodiment can further include one or more device sensors 92 configured to sense one or more of: the dose selected by a user using dosage selector 60, the dose metered by the metering mechanism 70 and the dose dispensed by the dispensing mechanism 20. Similarly, an environment sensor 94 is provided which is configured to sense information relating to the environment in which the device 500 is present, such as the temperature of the environment, the humidity of the environment, location, and time. There can be a dedicated location sensor 98 which is configured to determine the geographical location of the device 500, e.g., via satellite position determination, such as GPS. The device 500 also includes a communications interface 99 which can communicate externally data which has been acquired from the various sensors about the device and/or drug.
If required, the device 500 includes a power supply 95 for delivering electrical power to one or more electrical components of the device 500. The power supply 95 can be a source of power which is integral to device 500 and/or a mechanism for connecting device 500 to an external source of power. The drug administration device 500 also includes a computer system 90 including a processor 96 and a memory 97 powered by the power supply 95 and in communication with each other, and optionally with other electrical and control components of the device 500, such as the environment sensor 94, the location sensor 98, the device sensor 92, the communications interface 99, and/or the indicator 85. The processor 96 is configured to obtain data acquired from the environment sensor 94, the device sensor 92, the communications interface 99, the location sensor 98, and/or the user interface 80 and process it to provide data output, for example to indicator 85 and/or to communications interface 99.
In some embodiments, the drug administration device 500 is enclosed in packaging 35. The packaging 35 can further include a combination of a processor 96, a memory 97, a user interface 80, a device indicator 85, a device sensor 92, a location sensor 98, and/or environment sensors 94 as described herein, and these can be located externally on the housing of the device 500.
A person skilled in the art will appreciate that the universal drug administration device 500 including the drug holder 10 and the dispensing mechanism 20 can be provided with a variety of the optional features described above, in a number of different combinations. Moreover, the drug administration device 500 can include more than one drug holder 10, optionally with more than one dispensing mechanism 20, such that each drug holder 10 has its own associated dispensing mechanism 20.
Drug Dosage Forms
Conventionally, drug administration devices utilize a liquid dosage form. It will be appreciated by a person skilled in the art, however, that other dosage forms are available.
One such common dosage form is a tablet. The tablet may be formed from a combination of the drug and an excipient that are compressed together. Other dosage forms are pastes, creams, powders, ear drops, and eye drops.
Further examples of drug dosage forms include dermal patches, drug eluting stents and intrauterine devices. In these examples, the body of the device includes the drug and can be configured to allow the release of the drug under certain circumstances. For example, a dermal patch may include a polymeric composition containing the drug. The polymeric composition allows the drug to diffuse out of the polymeric composition and into skin of a patient. Drug eluting stents and intrauterine devices can operate in an analogous manner. In this way, the patches, stents, and intrauterine devices can themselves be considered drug holders with an associated dispensing mechanism.
Any of these dosage forms can be configured to have the drug release initiated by certain conditions. This can allow the drug to be released at a desired time or location after the dosage form has been introduced into the patient. In particular, the drug release can be initiated by an external stimulus. Moreover, these dosage forms can be contained prior to administration in a housing, which can be in the form of packaging. This housing can contain some of the optional features described above which are utilized with the universal drug administration device 500.

Drug Housings
As described above, a dosage form can be provided in a holder that is appropriate for the particular dosage form being utilized. For example, a drug in a liquid dosage form can be held prior to administration within a holder in the form of a vial with a stopper, or a syringe with a plunger. A drug in solid or powder dosage form, e.g., as tablets, can be contained in a housing which is arranged to hold the tablets securely prior to administration.
The housing can include one or a plurality of drug holders, where each holder contains a dosage form, e.g., the drug can be in a tablet dosage form and the housing can be in the form of a blister pack, where a tablet is held within each of a plurality of holders. The holders being in the form of recesses in the blister pack.
The housing 630 can include an indicator 85 which is configured to present information about the status of the drug of the dosage form 611 contained within the holder 610 to a user of the drug housing. The housing 630 can also include a communications interface 99 which can communicate information externally via a wired or wireless transfer of data pertaining to the drug housing 630, environment, time, or location and/or the drug itself.
If required, the housing 630 can include a power supply 95 for delivering electrical power to one or more electrical components of the housing 630. The power supply 95 can be a source of power which is integral to housing 630 and/or a mechanism for connecting the housing 630 to an external source of power. The housing 630 can also include a computer system 90 including a processor 96 and a memory 97 powered by the power supply 95 and in communication with each other, and optionally with other electrical and control components of the housing 630, such as the environment sensor 94, the location sensor 98, the device sensor 92, the communications interface 99, and/or the indicator 85. The processor 96 is configured to obtain data acquired from the environment sensor 94, the device sensor 92, the communications interface 99, the location sensor 98, and/or the user interface 80 and process it to provide data output, for example to the indicator 85 and/or to the communications interface 99.
The housing 630 can be in the form of packaging. Alternatively, additional packaging can be present to contain and surround the housing 630.
The holder 610 or the additional packaging the themselves include one or more of the device sensor 92, the environment sensor 94, the indicator 85, the communications interface 99, the power supply 95, location sensor 98, and the computer system including the processor 96 and the memory 85, as described above.
Electronic Communication
As mentioned above, the communications interface 99 can be associated with the drug administration device 500 or the drug housing 630, by being included within or on the housing 30, 630, or alternatively within or on the packaging 35. Such a communications interface 99 can be configured to communicate with a remote computer system, such as central computer system 700 shown in
A person skilled in the art will appreciate that the system 700 can include security features such that the aspects of the system 700 available to any particular user can be determined based on, e.g., the identity of the user and/or the location from which the user is accessing the system. To that end, each user can have a unique username, password, biometric data, and/or other security credentials to facilitate access to the system 700. The received security parameter information can be checked against a database of authorized users to determine whether the user is authorized and to what extent the user is permitted to interact with the system, view information stored in the system, and so forth.
Computer Systems
As discussed herein, one or more aspects or features of the subject matter described herein, for example components of the central computer system 700, the processor 96, the power supply 95, the memory 97, the communications interface 99, the user interface 80, the device indicators 85, the device sensors 92, the environment sensors 94, and the location sensors 98, can be realized in digital electronic circuitry, integrated circuitry, specially designed application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs) computer hardware, firmware, software, and/or combinations thereof. These various aspects or features can include implementation in one or more computer programs that are executable and/or interpretable on a programmable system including at least one programmable processor, which can be special or general purpose, coupled to receive data and instructions from, and to transmit data and instructions to, a storage system, at least one input device, and at least one output device. The programmable system or computer system can include clients and servers. A client and server are generally remote from each other and typically interact through a communications network, e.g., the Internet, a wireless wide area network, a local area network, a wide area network, or a wired network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.
The computer programs, which can also be referred to as programs, software, software applications, applications, components, or code, include machine instructions for a programmable processor, and can be implemented in a high-level procedural language, an object-oriented programming language, a functional programming language, a logical programming language, and/or in assembly/machine language. As used herein, the term “machine-readable medium” refers to any computer program product, apparatus and/or device, such as for example magnetic discs, optical disks, memory, and Programmable Logic Devices (PLDs), used to provide machine instructions and/or data to a programmable processor, including a machine-readable medium that receives machine instructions as a machine-readable signal. The term “machine-readable signal” as used herein refers to any signal used to provide machine instructions and/or data to a programmable processor. The machine-readable medium can store such machine instructions non-transitorily, such as for example as would a non-transient solid-state memory or a magnetic hard drive or any equivalent storage medium. The machine-readable medium can alternatively or additionally store such machine instructions in a transient manner, such as for example as would a processor cache or other random access memory associated with one or more physical processor cores.
To provide for interaction with a user, one or more aspects or features of the subject matter described herein, for example the user interface 80 (which can be integrated or separate to the administration device 500 or the housing 630), can be implemented on a computer having a display screen, such as for example a cathode ray tube (CRT) or a liquid crystal display (LCD) or a light emitting diode (LED) monitor for displaying information to the user. The display screen can allow input thereto directly (e.g., as a touch screen) or indirectly (e.g., via an input device such as a keypad or voice recognition hardware and software). Other kinds of devices can be used to provide for interaction with a user as well. For example, feedback provided to the user can be any form of sensory feedback, such as for example visual feedback, auditory feedback, or tactile feedback; and input from the user may be received in any form, including, but not limited to, acoustic, speech, or tactile input. As described above, this feedback may be provided via one or more device indicators 85 in addition to the user interface 80. The device indicators 85 can interact with one or more of the device sensor(s) 92, the environment sensor(s) 94, and/or the location sensor(s) 98 in order to provide this feedback, or to receive input from the user.
The various elements of the computer system are coupled to a bus system 812. The illustrated bus system 812 is an abstraction that represents any one or more separate physical busses, communication lines/interfaces, and/or multi-drop or point-to-point connections, connected by appropriate bridges, adapters, and/or controllers. The computer system 800 also includes one or more network interface(s) 899 (also referred to herein as a communications interface), one or more input/output (IO) interface(s) 880, and one or more storage device(s) 810.
The communications interface(s) 899 are configured to enable the computer system to communicate with remote devices, e.g., other computer systems and/or devices 500 or housings 630, over a network, and can be, for example, remote desktop connection interfaces, Ethernet adapters, and/or other local area network (LAN) adapters. The IO interface(s) 880 include one or more interface components to connect the computer system 800 with other electronic equipment. For example, the IO interface(s) 880 can include high speed data ports, such as universal serial bus (USB) ports, 1394 ports, Wi-Fi, Bluetooth, etc. Additionally, the computer system 800 can be accessible to a human user, and thus the IO interface(s) 880 can include displays, speakers, keyboards, pointing devices, and/or various other video, audio, or alphanumeric interfaces. The storage device(s) 810 include any conventional medium for storing data in a non-volatile and/or non-transient manner. The storage device(s) 810 are thus configured to hold data and/or instructions in a persistent state in which the value(s) are retained despite interruption of power to the computer system. The storage device(s) 810 can include one or more hard disk drives, flash drives, USB drives, optical drives, various media cards, diskettes, compact discs, and/or any combination thereof and can be directly connected to the computer system or remotely connected thereto, such as over a network. In an exemplary embodiment, the storage device(s) 810 include a tangible or non-transitory computer readable medium configured to store data, e.g., a hard disk drive, a flash drive, a USB drive, an optical drive, a media card, a diskette, or a compact disc.
The elements illustrated in
The computer system 800 can include a web browser for retrieving web pages or other markup language streams, presenting those pages and/or streams (visually, aurally, or otherwise), executing scripts, controls and other code on those pages/streams, accepting user input with respect to those pages/streams (e.g., for purposes of completing input fields), issuing HyperText Transfer Protocol (HTTP) requests with respect to those pages/streams or otherwise (e.g., for submitting to a server information from the completed input fields), and so forth. The web pages or other markup language can be in HyperText Markup Language (HTML) or other conventional forms, including embedded Extensible Markup Language (XML), scripts, controls, and so forth. The computer system 800 can also include a web server for generating and/or delivering the web pages to client computer systems.
As shown in
As mentioned the computer system 800 as described above can also form the components of a device computer system 90 which is integrated into or in close proximity to the drug administration device 500 or housing 630. In this regard, the one or more processors 896 correspond to the processor 96, the network interface 799 corresponds to the communications interface 99, the IO interface 880 corresponds to the user interface 80, and the memory 897 corresponds to the memory 97. Moreover, the additional storage 810 can also be present in device computer system 90.
In an exemplary embodiment, the computer system 800 can form the device computer system 90 as a single unit, e.g., contained within a single drug administration device housing 30, contained within a single package 35 for one or more drug administration devices 500, or a housing 630 that includes a plurality of drug holders 610. The computer system 800 can form the central computer system 700 as a single unit, as a single server, or as a single tower.
The single unit can be modular such that various aspects thereof can be swapped in and out as needed for, e.g., upgrade, replacement, maintenance, etc., without interrupting functionality of any other aspects of the system. The single unit can thus also be scalable with the ability to be added to as additional modules and/or additional functionality of existing modules are desired and/or improved upon.
The computer system can also include any of a variety of other software and/or hardware components, including by way of example, operating systems and database management systems. Although an exemplary computer system is depicted and described herein, it will be appreciated by a person skilled in the art that this is for sake of generality and convenience. In other embodiments, the computer system may differ in architecture and operation from that shown and described here. For example, the memory 897 and the storage device 810 can be integrated together, or the communications interface 899 can be omitted if communication with another computer system is not necessary.
Surgical Hubs
In an exemplary embodiment, the computer system to which data regarding drug administration devices and/or surgical instruments is communicated includes a surgical hub. Exemplary examples of surgical hubs configured to receive, analyze, and output data, and methods of using such surgical hubs, are further described in U.S. Pat. Pub. No. 2019/0200844 entitled “Method Of Hub Communication, Processing, Storage And Display” filed Dec. 4, 2018, U.S. Pat. Pub. No. 2019/0201114 entitled “Adaptive Control Program Updates For Surgical Hubs” filed Mar. 29, 2018, U.S. Pat. Pub. No. 2019/0207857 entitled “Surgical Network Determination Of Prioritization Of Communication, Interaction, Or Processing Based On System Or Device Needs” filed Nov. 6, 2018, and U.S. Pat. Pub. No. 2019/0206555 entitled “Cloud-based Medical Analytics For Customization And Recommendations To A User” filed Mar. 29, 2018, which are hereby incorporated by reference in their entireties.
In general, a surgical hub can be a component of a comprehensive digital medical system capable of spanning multiple medical facilities and configured to provide integrated and comprehensive improved medical care to a vast number of patients. The comprehensive digital medical system includes a cloud-based medical analytics system that is configured to interconnect to multiple surgical hubs located across many different medical facilities. The surgical hubs are configured to interconnect with one or more elements, such as one or more surgical instruments that are used to conduct medical procedures on patients and/or one or more drug administration device that are used to administer one or more drugs to patients during performance of medical procedures. The surgical hubs provide a wide array of functionality to improve the outcomes of medical procedures. The data generated by the various surgical devices, drug administration devices, and surgical hubs about the patient and the medical procedure may be transmitted to the cloud-based medical analytics system. This data may then be aggregated with similar data gathered from many other surgical hubs, drug administration devices, and surgical instruments located at other medical facilities. Various patterns and correlations may be found through the cloud-based analytics system analyzing the collected data. Improvements in the techniques used to generate the data may be generated as a result, and these improvements may then be disseminated to the various surgical hubs, drug administration devices, and surgical instruments. Due to the interconnectedness of all of the aforementioned components, improvements in medical procedures and practices may be found that otherwise may not be found if the many components were not so interconnected. Various examples of structures and functions of these various components are described in more detail in previously mentioned U.S. Pat. Pub. No. 2019/0200844 entitled “Method Of Hub Communication, Processing, Storage And Display” filed Dec. 4, 2018, U.S. Pat. Pub. No. 2019/0201114 entitled “Adaptive Control Program Updates For Surgical Hubs” filed Mar. 29, 2018, U.S. Pat. Pub. No. 2019/0207857 entitled “Surgical Network Determination Of Prioritization Of Communication, Interaction, Or Processing Based On System Or Device Needs” filed Nov. 6, 2018, and U.S. Pat. Pub. No. 2019/0206555 entitled “Cloud-based Medical Analytics For Customization And Recommendations To A User” filed Mar. 29, 2018.
Modular devices 1a-1n, e.g., any number of surgical instruments such as instruments 1012 and/or any number of drug delivery devices such as devices 1014, located in the operating theater can be coupled to the modular communication hub 1103. The network hub 1107 and/or the network switch 1109 can be coupled to a network router 1111 to connect the devices 1a-1n to the cloud 1104 or the local computer system 1110. Data associated with the devices 1a-ln can be transferred to cloud-based computers via the router for remote data processing and manipulation. Data associated with the devices 1a-1n can also be transferred to the local computer system 1110 for local data processing and manipulation. Modular devices 2a-2n, located in the same operating theater also can be coupled to a network switch 1109. The network switch 1109 can be coupled to the network hub 1107 and/or the network router 1111 to connect to the devices 2a-2m to the cloud 1104. Data associated with the devices 2a-2n can be transferred to the cloud 1104 via the network router 1111 for data processing and manipulation. Data associated with the devices 2a-2m can also be transferred to the local computer system 1110 for local data processing and manipulation. The numbers n, m of the devices 1a-1n/2a-2m can be the same as or different from one another.
A person skilled in the art will appreciate that the surgical data network 1101 can be expanded by interconnecting multiple network hubs 1107 and/or multiple network switches 1109 with multiple network routers 1111. The modular communication hub 1103 can be contained in a modular control tower configured to receive multiple devices 1a-1n/2a-2m. The local computer system 1110 also can be contained in a modular control tower. The modular communication hub 1103 is connected to a display 1112 to display images obtained by at least some of the devices la-1n/2a-2m for example during surgical procedures.
The surgical data network 1101 can include a combination of network hub(s), network switch(es), and network router(s) connecting the devices 1a-1n/2a-2m to the cloud 1104. Any one of or all of the devices 1a-1n/2a-2m coupled to the network hub 1107 or network switch 1109 can collect data in real time and transfer the data to cloud computers for data processing and manipulation. Alternatively or in addition, any one or all of the devices 1a-1n/2a-2m coupled to the network hub 1107 or network switch 1109 can transfer previously collected data, such as sensor data, to cloud computers for data processing and manipulation, e.g., once the one or all of the devices 1a-1n/2a-2m is operatively connected to the cloud 1104 via the communication hub 1103. A person skilled in the art will appreciate that cloud computing relies on sharing computing resources rather than having local servers or personal devices to handle software applications. The term “cloud” can be used as a metaphor for “the Internet,” although the term is not limited as such. Accordingly, the term “cloud computing” may be used herein to refer to “a type of Internet-based computing,” where different services, such as servers, storage, and applications, are delivered to the modular communication hub 1103 and/or the computer system 1110 located in the surgical theater (e.g., a fixed, mobile, temporary, or field operating room or space) and to devices connected to the modular communication hub 1103 and/or the computer system 1110 through the Internet. The cloud infrastructure can be maintained by a cloud service provider. In this context, the cloud service provider can be the entity that coordinates the usage and control of the devices 1a-1n/2a-2m located in one or more operating theaters. The cloud computing services can perform a large number of calculations based on the data gathered by smart surgical instruments, smart drug delivery devices, robots, and other computerized devices located in the operating theater. The hub hardware enables multiple devices or connections to be connected to a computer that communicates with the cloud computing resources and storage.
Applying cloud computer data processing techniques on the data collected by the devices 1a-1n/2a-2m the surgical data network may provide improved surgical outcomes, reduced costs, and/or improved patient satisfaction. At least some of the devices 1a-1n/2a-2m, e.g., one or more of the surgical instruments 1012, can be employed to view tissue states to assess leaks or perfusion of sealed tissue after a tissue sealing and cutting procedure. At least some of the devices 1a-1n/2a-2m, e.g., one or more of the surgical instruments 1012, can be employed to identify pathology, such as the effects of diseases, using the cloud-based computing to examine data including images of samples of body tissue for diagnostic purposes. This includes localization and margin confirmation of tissue and phenotypes. At least some of the devices la-1n/2a-2m, e.g., one or more of the surgical instruments 1012, can be employed to identify anatomical structures of the body using a variety of sensors integrated with imaging devices and techniques such as overlaying images captured by multiple imaging devices. At least some of the devices 1a-1n/2a-2m, e.g., one or more of the drug delivery devices 1014, can be employed to identify dimensions of a patient's bariatric sleeve in bariatric surgical intervention using, e.g., an insulin pump, to facilitate visualization of the sleeve. The data gathered by the devices la-1n/2a-2m, including image data, can be transferred to the cloud 1104 or the local computer system 1110 or both for data processing and manipulation including image processing and manipulation. The data can be analyzed to improve surgical procedure outcomes by determining if further treatment, such as the application of endoscopic intervention, emerging technologies, a targeted radiation, targeted intervention, precise robotics to tissue-specific sites and conditions, and drug administration may be pursued. Such data analysis can further employ outcome analytics processing, and using standardized approaches may provide beneficial feedback to either confirm surgical treatments and the behavior of the surgeon or suggest modifications to surgical treatments, surgeon behavior, drug delivery devices, and/or drugs.
The operating theater devices 1a-1n can be connected to the modular communication hub 1103 over a wired channel or a wireless channel depending on the configuration of the devices 1a-1n to a network hub. The network hub 1107 can be implemented as a local network broadcast device that works on the physical layer of the Open System Interconnection (OSI) model. The network hub provides connectivity to the devices 1a-1n located in the same operating theater network. The network hub 1107 collects data in the form of packets and sends them to the router 1111 in half duplex mode. The network hub 1107 does not store any media access control/Internet Protocol (MAC/IP) to transfer the device data. Only one of the devices 1a-1n can send data at a time through the network hub 1107. The network hub 1107 has no routing tables or intelligence regarding where to send information and broadcasts all network data across each connection and to a remote server over the cloud 1104. The network hub 1107 can detect basic network errors such as collisions, but having all information broadcast to multiple ports can be a security risk and cause bottlenecks.
The operating theater devices 2a-2m can be connected to a network switch 1109 over a wired channel or a wireless channel. The network switch 1109 works in the data link layer of the OSI model. The network switch 1109 is a multicast device for connecting the devices 2a-2m located in the same operating theater to the network. The network switch 1109 sends data in the form of frames to the network router 1111 and works in full duplex mode. Multiple devices 2a-2m can send data at the same time through the network switch 1109. The network switch 1109 stores and uses MAC addresses of the devices 2a-2m to transfer data.
The network hub 1107 and/or the network switch 1109 are coupled to the network router 1111 for connection to the cloud 1104. The network router 1111 works in the network layer of the OSI model. The network router 1111 creates a route for transmitting data packets received from the network hub 1107 and/or the network switch 1111 to cloud-based computer resources for further processing and manipulation of the data collected by any one of or all the devices la-1n/2a-2m. The network router 1111 can be employed to connect two or more different networks located in different locations, such as, for example, different operating theaters of the same healthcare facility or different networks located in different operating theaters of different healthcare facilities. The network router 1111 sends data in the form of packets to the cloud 1104 and works in full duplex mode. Multiple devices can send data at the same time. The network router 1111 uses IP addresses to transfer data.
In one example, the network hub 1107 can be implemented as a USB hub, which allows multiple USB devices to be connected to a host computer. The USB hub can expand a single USB port into several tiers so that there are more ports available to connect devices to the host system computer. The network hub 1107 can include wired or wireless capabilities to receive information over a wired channel or a wireless channel. A wireless USB short-range, high-bandwidth wireless radio communication protocol cab be employed for communication between the devices 1a-1n and devices 2a-2m located in the operating theater.
In other examples, the operating theater devices 1a-1n/2a-2m can communicate to the modular communication hub 1103 via Bluetooth wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices and building personal area networks (PANs). In other aspects, the operating theater devices 1a-1n/2a-2m can communicate to the modular communication hub 1103 via a number of wireless or wired communication standards or protocols, including but not limited to Wi-Fi (IEEE 802.11 family), WiMAX (IEEE 802.16 family), IEEE 802.20, long-term evolution (LIE), and Ev-DO, HSPA+, HSDPA+, HSUPA+, EDGE, GSM, GPRS, CDMA, TDMA, DECT, and Ethernet derivatives thereof, as well as any other wireless and wired protocols that are designated as 3G, 4G, 5G, and beyond. The computing module can include a plurality of communication modules. For example, a first communication module may be dedicated to shorter-range wireless communications such as Wi-Fi and Bluetooth, and a second communication module can be dedicated to longer-range wireless communications such as GPS, EDGE, GPRS, CDMA, WiMAX, LTE, Ev-DO, and others.
The modular communication hub 1103 can serve as a central connection for one or all of the operating theater devices 1a-1n/2a-2m and handle a data type known as frames. Frames carry the data generated by the devices 1a-1n/2a-2m. When a frame is received by the modular communication hub 1103, it is amplified and transmitted to the network router 1111, which transfers the data to the cloud computing resources by using a number of wireless or wired communication standards or protocols, as described herein.
The modular communication hub 1103 can be used as a standalone device or be connected to compatible network hubs and network switches to form a larger network. The modular communication hub 1103 is generally easy to install, configure, and maintain, making it a good option for networking the operating theater devices 1a-1n/2a-2m.

The sensors described herein can be configured to gather data regarding a variety of conditions, such as device conditions (e.g., as sensed by the device sensor 92), environmental conditions (e.g., as sensed by the environment sensor 94), and location conditions (e.g., as sensed by the location sensor 98). Examples of conditions include geographic location (e.g., as sensed by a location sensor configured to sense GPS or other location), time (e.g., as sensed by a timer or a clock device such as an atomic clock), date (e.g., as sensed by a timer), temperature (e.g., as sensed by a temperature sensor such as a thermistor, a thermocoupler, a thermistor, etc.), ultraviolet (UV) exposure (e.g., as sensed by a UV sensor configured to sense UV level), humidity (e.g., as sensed by a humidity sensor configured to sense humidity level such as a thermistor, a humistor, a hygrometer, etc.), pressure (e.g., as sensed by a pressure sensor), angular rate (e.g., as sensed by an inertial measurement unit (IMU) or MARG (magnetic, angular rate, and gravity) sensor), body orientation (e.g., using an IMU, an accelerometer, etc.), current of a motor used in delivering the drug (e.g., using a current sensor), blood oxygenation level (e.g., using a blood oxygen sensor), sun exposure (e.g., using a UV sensor, etc.), osmolality (e.g., using a blood monitor, etc.), and air quality (e.g., using a UV sensor, etc.). The conditions can be physiological conditions and/or situational conditions of the patient. Various different physiological conditions can be monitored, such as blood sugar level (e.g., using a glucose monitor, etc.), blood pressure (e.g., using a blood pressure monitor, etc.), perspiration level (e.g., using a fluid sensor, etc.), heart rate (e.g., using a heart rate monitor, etc.), etc. A number of different situational conditions can be monitored, such as core temperature, (e.g., using a temperature sensor such as a thermistor, a thermocoupler, a thermistor, etc.), tremor detection (using an accelerometer, etc.), time of day (e.g., using a timer, etc.), date (e.g., using a timer, etc.), patient activity level (e.g., using a motion sensor, etc.), blood pressure (e.g., using a blood pressure monitor, etc.), metabolic rate (e.g., using heart rate as discussed herein, etc.), altitude (e.g., using an altimeter, etc.), temperature of the drug (e.g., using a temperature sensor such as a thermistor, a thermocoupler, a thermistor, etc.), viscosity of the drug (e.g., using a viscometer, etc.), GPS information (e.g., using a location sensor, etc.), weather information (e.g., using a temperature sensor, humidity sensor, etc.), room or external temperature (e.g., using a temperature sensor such as a thermistor, a thermocoupler, a thermistor, etc.), angular rate (e.g., using an inertial measurement unit (IMU) or MARG (magnetic, angular rate, and gravity) sensor), body orientation (e.g., using an IMU, an accelerometer, etc.), current of a motor used in delivering the drug (e.g., using a current sensor), blood oxygenation level (e.g., using a blood oxygen sensor), sun exposure (e.g., using a UV sensor, etc.), osmolality (e.g., using a blood monitor, etc.), and air quality (e.g., using a UV sensor, etc.), inflammatory response, one or more images and/or videos of the patient and/or an environment in which the patient is located (for example, to analyze food intake; to determine whether solid food or liquid is being consumed; to determine a location or activity of the patient; to determine a condition of the patient such as skin reaction, breathing, eye dilation, voice characteristics such as tone and pitch; etc.), user-input data such as general well-being, pain score, or a cycle time between flare ups of a particular ailment, etc.
In various embodiments, a sensor includes an image capturing device such as a camera, and a processor is configured to analyze image(s) and/or video(s) captured by the image capturing device, such as to analyze any food/drink intake and/or patient skin reaction to the drug. U.S. Pat. Pub. No. 2012/0330684 entitled “Medication Verification And Dispensing” published Dec. 27, 2012, which is incorporated by reference herein in its entirety, further describes image capturing devices. Analyzing food/drink intake can include analysis of images captured by the image capturing device to visually identify a variety of types of information about food and/or drink that a user is consuming, such as food and/or drink type, food and/or drink amount, amount of food remaining on plate, amount of drink remaining in a cup, etc. U.S. Pat. Pub. No. 2011/0295337 entitled “Systems and Methods For Regulating Metabolic Hormone Producing Tissue” filed on Dec. 1, 2011, U.S. Pat.

U.S. Pat. Pub. No. 2002/0014951 entitled “Remote Control For A Hospital Bed” published Feb. 7, 2002, and U.S. Pat. Pub. No. 2007/0251835 entitled “Subnetwork Synchronization And Variable Transmit Synchronization Techniques For A Wireless Medical Device Network” published Nov. 1, 2007, further discuss various sensors and are hereby incorporated by reference herein in their entireties.
In at least some embodiments, the drug administration device's processor and/or another processor (e.g., a processor of a surgical hub, a processor of a cloud-based server, or other processor) is configured to use a hierarchy in terms of how data from each of a plurality of sensors is used compared to each other, where each of the sensors is configured to monitor a different condition. The hierarchy prioritizes one of the sensors over the other(s) such that one sensor acts as a primary sensor and the other sensor(s) act as secondary or ancillary sensor(s). In such embodiments, the condition measured by the primary sensor can be considered to be the primary or defining condition, and condition(s) measured by the secondary sensor(s) can be secondary or influencing conditions on the primary condition. This prioritization or hierarchy of conditions (and thus data) can be helpful, for example, when the drug administration device is used for a treatment that includes one controlling condition and one or more secondary conditions that may influence or assist in monitoring the controlling condition, for example when measuring blood pressure when administering blood pressure medication or when measuring blood sugar level when administering insulin. While secondary conditions can help in monitoring high blood pressure or low blood sugar, the conditions of primary concern in each example is blood pressure itself or blood sugar level itself. The prioritization of data and inputs from one or more secondary sensors based on the hierarchical relationship can be customizable based on desired patient outcomes, various expected or anticipated side-effects, the drug being administered, time of day, location, activity level, caloric intake, physical activity, etc. The drug administration device can thus have associated therewith a predefined hierarchy of levels or severity of effect on dosage based on the sensed conditions from the sensor(s). A medical professional or unlearned algorithm within the drug administration device itself and/or a computer system (e.g., a surgical hub, a cloud-based system, etc.) in communication with the drug administration device can optionally adjust the priority of the levels or reorder the importance of the various sensed data and inputs as a result of dosing amounts and/or dosing timelines. Because so much data can be generated by using a plurality of sensors and because data from one sensor may contradict data from another sensor in some instances, effectively using situational awareness to personalize drug administration to each patient may benefit from prioritization and relative weighing of multiple sources of information to arrive at a most correct conclusion or recommendation to best help the patient. This hierarchy of prioritization can be customized for a specific patient based on how the patient presents in any one moment or over time, therefore providing an adaptive device with re-orderable hierarchal relationships.
As mentioned above, the hierarchical arrangement can be used in a variety of ways, for example to verify a physiological result such that data from one or more sensors is considered to adjust at least one variable parameter of the drug administration device's control program, discussed further below, to proactively manage any anticipated negative effect on the primary characteristic being measured. The hierarchy between various sensors can be predefined; can be adaptable based on user input, such as providing input through a drug administration device's and/or a computer system's user interface; can be adaptable based on a processor, an algorithm, any analyzed data, etc.; and/or can be adaptable through contact with remote computer systems, doctors, remote-care providers, etc.
In general, a primary condition for a drug administration device can be a control measure, and secondary condition(s) or measures can be data taken from sources surrounding the primary condition and/or sources that can influence and/or be influenced by the primary source. For example, blood sugar level is a primary condition for insulin delivery, but blood pressure is a primary condition for various blood pressure medications. Additionally, sources surrounding the primary source can take a variety of different forms, such as glucose level (for example, as measured by a micro needle application and/or sweat analysis); blood pressure (for example, as measured by various wearable cuffs); hydration (for example, as measured by perspiration level); heart rate and/or activity level (for example, as measured by various metabolic consumption rates, sitting or sedentary motion determined by elevation changes, various gyroscopes); EKG cycle; heart rate variability; various acute effects or activities to trigger measurement (such as sleep or sleep quality detection and/or meal detection, for example by analyzing one or more images of the patient, receiving input from the patient, etc.); discernment between eating and drinking; various long term effects to monitor any changes that might inform a new diagnoses or provide alerts to seek evaluation for any possible new conditions; core temperature; tremor detection; patient held/worn camera image analysis; time of day; digital calendar information; GPS outputs; device activity; any user interaction with the drug administration device; etc.
Additionally, numerous means for being aware of any surrounding situation during administration of the drug from the drug administration device are possible, providing a variety of types of situational awareness that one or more drug administration devices can use. As further examples, forms of cognitive analysis can be performed on the patient by combining small interactions with the patient and various automated sensors on or around the patient to determine cognitive effects of any drug dosage on the patient. Various measured reactions to drug dosages can also be analyzed, such as timing to a first effect, effect duration, magnitude of effect, etc. Ending continued application of a drug can be one result, however there are many other examples where such an action can be taken. For example, if a biologic or drug is being delivered on an ongoing basis, the plurality of sensors can allow detection of an onset of a complex biologic response to the biologic or drug, and a drug administration device can have the ability to affect, retard, or end the continued application of the biologic or drug. Thus, drug administration devices, surgical hubs, and/or other computer systems described herein can be configured to provide detection of and an automated response to collateral physiologic reactions to any continuous biologic introduction. For example, injection reactions can be an issue for some biologics, especially when delivered through an IV given delivery times and the continuous administration. Thus, drug administration devices, surgical hubs, and/or other computer systems described herein can be configured to detect various onsets of injection reactions, such as through sensor(s), and consequently stop or slow down delivery of the drug. In at least some embodiments, drug administration devices described herein can be configured to deliver other medication(s) to stop, lessen, or counteract the drug injection reaction. As another example, cytokine release syndrome is a form of systemic inflammatory response syndrome that can arise from an adverse effect of some monoclonal antibody drugs, as well as adoptive T-cell therapies. Once a drug administration device, or other system in communication with the drug administration device, detects pro- and anti-inflammatory components above a predetermined threshold in a patient, the drug administration device can be configured to reduce or stop the introduction of the treatment. In such an example, the drug administration device, surgical hubs, and/or other computer systems can also be configured to notify medical personnel or introduce a canceling agent to accelerate the reduction of the response. If the injection response is great enough as defined by predefined criteria, the drug administration device can be configured to automatically escalate its response, or a surgical hub (and/or other computer system) can be configured to cause the drug administration device to escalate its response, from a passive indication or reduction of dosage to a more active warning notification or introductions of other active countermeasures. Even when medical intervention is required, such as requiring a patient to go into a hospital for emergency treatment or altering a pre-operative plan during surgery, the drug administration devices and surgical hubs (and other computer systems) described herein can be configured to use biometric data to detect changes in the patient's body, such as body temperature or heart rate, that typically proceed a serious effect. The drug administration device and/or the surgical hub (and/or other computer system) can be configured to notify the patient and/or medical personnel of the imminent effect to allow the patient and/or medical personnel to take preemptive action, such as taking medication at home before then going into the hospital before one or more major side effects take place, preparing another drug for delivery, etc. This early warning can improve patient outcomes by reducing any negative consequences.
Using the drug administration device 500 of
In addition or in alternative to the drug administration device 500 being configured to transmit data indicative of the information sensed by the drug administration device's one or more sensors 92, 94, 98 automatically, the drug administration device 500 can be configured to transmit data to the system 700 on demand in reply to a request for data from the system 700 to the drug administration device 500. Transmitting data on demand may help conserve device power and resources and/or may help ensure that the system 700 only receives data it needs to perform a particular analysis. The system 700 can be configured to transmit the request to the drug administration device 500 according to a predetermined schedule, e.g., transmit data every hour, every three hours, every twelve hours, once daily, etc., and/or can be configured to transmit the request in response to a user input to the system 700 requesting that the drug administration device 500 be queried for sensed information.
In addition or in alternative to the drug administration device 500 being configured to transmit data indicative of the information sensed by the device's one or more sensors 92, 94, 98 according to a predetermined schedule and/or on demand from the system 700, the drug administration device 500 can be configured to be manually triggered by a user to transmit data on demand to the computer system 700, such as by user input to the user interface 80. Such on demand data transmission may allow, for example, data related to an event that occurs during performance of a surgical procedure in which the drug administration device 500 is being used to be transmitted to the system 700 for timely analysis related to the event.
The system 700 can be configured to store data received from the drug administration device 500 for analysis at a subsequent time. For example, the system 700 can be configured to perform an analysis on demand in response to a user input to the system 700 requesting one or more types of analysis, such as any one or more of the analyses discussed further below. Performing analysis on demand may help conserve system power and resources and/or may help ensure that the user receives analysis output from the system 700 based on the most current data available to the system 700. For another example, the system 700 can be configured to perform an analysis automatically according to a predetermined schedule, e.g., analyze data every hour, every three hours, every twelve hours, once daily, once the system 700 has received a predetermined number of data transmissions from the drug administration device 500 and/or other drug administration devices so as to have a sufficient amount of new data to include in an analysis, etc. In addition or in alternative, the system 700 can be configured to perform an analysis in response to receipt of the data from the drug administration device 500, e.g., perform an analysis every time the system 700 receives a certain type and/or certain amount of data from the drug administration device 500, etc. Data receipt being a trigger for analysis may help more quickly identify problems with the drug administration device 500 and/or the drug, which in turn may allow the problems to be addressed more quickly by a medical professional and/or a user of the drug administration device 500.
In general, analysis performed by the system 700 uses sensed information from the drug administration device 500 and, in at least some analyses, one or more additional drug administration devices 500. In an exemplary embodiment in which the system 700 is analyzing data received from multiple drug administration devices 500, each of the drug administration devices 500 is of a same type (e.g., is each the same type of autoinjector, inhaler, infusion pump, etc.), is delivering a same type of drug, and/or is delivering the same drug. The data analyzed may therefore yield significant, meaningful results related to a specific type of drug administration device, a specific type of drug, and/or a specific drug. The data collected by the system 700 from the multiple drug administration devices 500 can each be indicative of a same type of sensed information, e.g., drug temperature information, GPS information, dose timing information, etc. Collection of the same types of information from multiple drug administration devices 500 may allow the system 700 to continually review the data and discover trends in the data between patients and relate these trends to patient type, drug administration device type, and functional outcomes. These relationships can be evaluated by the system 700 through multiple algorithms to provide more accurate trends and/or more accurate recommendations, e.g., recommendations of treatments for the patient and their symptoms to result in an optimized outcome, recommendations that result in cost saving, recommendations that result in fewer and/or less severe side effects, etc.
In general, data transmitted from the drug administration device 500 via the network 702 can be received by the system 700. The transmitted data can be aggregated and processed by the system 700. Data including patient medical record data, physician summary data, drug specification data, and financial data associated with the costs of providing care to the patient can be shared via the network 702 and aggregated by the system 700 for use in determining and predicting clinical outcomes, such as that discussed above regarding the surgical hub 1006 communicating with the cloud 1004 of
In one implementation, the system 700 can be configured to receive data transmitted from the drug administration device 500 and to process the data to correlate a patient's use of a drug with a clinical outcome. A clinical outcome generally includes a measurable change in a state of health, functioning, or quality of life that can occur as a result of a clinical treatment, such as administering a drug in or out of a surgical setting, or receiving a therapeutic treatment. Clinical outcomes can be determined based on data that is received from a patient in response to a prompt, such as a questionnaire or other a similarly formatted self-reported assessment. Clinical outcomes can also be determined based on data that is collected from the patient and is provided by healthcare practitioners. The clinical outcome data can be stored in a database of patient medical files, a hospital information system, or the like and can be transmitted to and/or stored in a memory of the system 700 and/or a memory of another computer system to which the system 700 transmits the data. Although the foregoing describes collecting clinical outcome data via patient self-reporting or by a healthcare provider as inputs to a form or questionnaire, such as a health assessment form which may be implemented on an app that is configured on a mobile computing device, a person skilled in the art will appreciate that clinical outcome data can be captured in other ways and that devices other than mobile computing devices can be used to collect clinical outcome data with or without running an app. A person skilled in the art will appreciate that data can be captured in a variety of ways, e.g., using a camera (standalone or integrated into another device such as a mobile phone or tablet); a video camera (standalone or integrated into another device such as a mobile phone or tablet); one or more sensors (e.g., gyro, accelerometer, global position system (GPS), image (e.g., camera or video camera), etc.) on a smartphone, surgical instrument, etc., in a skin patch (e.g., patches available from MC10 Inc. of Cambridge, Mass.), integrated into smart clothing, or in additional sensing or monitoring devices that can connect to the drug administration device 500 or the system 700 via wireless or wired connection, etc.; as well as any of a variety of known motion capture apps or motion capture software; etc. Further information regarding clinical outcomes and collecting patient data is provided in U.S. Pat. Pub. No. 2014/0081659 entitled “Systems and Method for Surgical and Interventional Planning, Support, Post-operative Follow-up, and Functional Recovery Tracking” published Mar. 20, 2014, which is hereby incorporated by reference in its entirety.
Once received by the system 700, the clinical outcome data can be aggregated with the data that is received from the drug administration device 500. The system 700 can analyze the aggregated data to identify trends and correlations which may exist between the drug and drug administration data received from the drug administration device 500 and the clinical outcome data. Additionally, the system 700 can receive data from one or more additional drug administration devices 500 and/or drug housing(s) 630 to identify trends and correlations among a patient population.
Such correlations can be determined, for example, by one or more data processing components, each associated with a data processor, of the system 700 which implement an artificial intelligence (AI) and machine learning system. Machine learning is an application of artificial intelligence that automates the development of a predictive model by using algorithms that iteratively learn patterns from data without explicit indication of the data patterns. Machine learning is commonly used in pattern recognition, computer vision, language processing and optical character recognition and enables the construction of algorithms that can accurately learn from data to predict model outputs thereby making data-driven predictions or decisions. Machine learning can be utilized to develop predictive models capable of generating clinical outcomes that are associated with one or more aspects of a patient's treatment, such as the patient's use of a drug administration device, a patient's conformance with a particular drug delivery schedule, surgery performed on the patient in which the drug administration device was used, etc.
The artificial intelligence and machine learning system configured within the system 700 can include one or more predictive models or algorithms which have been trained in a machine learning process or which implement a layered structure of deep learning algorithms, also known as an artificial neural network, which can continually analyze data and generate predations using the artificial neural network. The system 700 can perform untrained or deep learning to predict clinical outcomes based on the drug administration device usage and drug delivery data that is received from the drug administration device 500 (and/or additional drug administration device(s) 500 and/or drug housing(s) 630). In this way, features of drug administration device usage and/or drug delivery data can be used to accurately predict a specific clinical outcome. For example, the artificial neural network can process a diabetic patient's insulin injector usage data which indicated that the patient moderately adhered to a prescribed twice-daily insulin delivery timing and can determine a predicted clinical outcome indicating that the patient is unlikely to receive a protective reduction in elevated blood glucose levels. Further information regarding implementations of neural networks is provided in U.S. Pat. Pub. No. 2018/0189638 entitled “Hardware Accelerator Template Design Framework For Implementing Recurrent Neural Networks” published Jul. 5, 2018, which is hereby incorporated by reference in its entirety.
The artificial intelligence and machine learning system configured within the system 700 can include data processing components, each associated with a data processor, to perform trend analysis which can identify trends and variations in drug administration device usage and drug delivery data over time, in a surgical setting or otherwise. The trend analysis can include time-series data associated with how the self-reported or predicted clinical outcomes vary over time. The trend analyses can be compared to desired or predetermined patterns of drug administration device usage and drug delivery data as well as desired or predetermined patterns of clinical outcome data, including post-operative data. Such determinations can be made regarding the compliance of drug administration over time and the expected clinical outcome that may result based on the compliance determination. Evaluating compliance can thus allow monitoring and management of a patient's treatment, which can help the patient's doctor (and/or other medical professional) evaluate the patient's medical progress and/or can help determine whether and when modifications to the patient's treatment plan may be necessary, such as by adjusting the treatment plan (e.g., changing a dose size of the drug delivered from the drug administration device 500, changing a timing of doses delivered by the drug delivery device 500, changing dietary requirements, changing a frequency of doctor check-ups, etc.) or replacing the treatment plan (e.g., a treatment plan including use of the drug administration device 500 delivering a specific drug) with another treatment plan (e.g., a treatment that does not include any use of the drug administration device 500 and/or the specific drug). Further information regarding compliance determinations is provided in previously mentioned U.S. Pat. Pub. No. 2014/0081659 entitled “Systems And Methods For Surgical And Interventional Planning, Support, Post-Operative Follow-Up, And Functional Recovery Tracking” published Mar. 20, 2014.
For example, compliance data (e.g., data indicative of when a patient received doses from the drug administration device 500 in a surgical setting or otherwise) as compared to when the doses were prescribed per the patient's treatment plan) can be compared with historic compliance data for other patients who used the same type of drug administration device 500 and/or who received the same drug to help determine the effectiveness of the drug administration device 500 and/or the drug for the patient. The comparison can allow the system 700 to determine whether a patient and/or surgeon (and/or other medical professional) is adequately following the treatment plan or is lagging behind historical benchmarks achieved by other patients undergoing the treatment. The comparison can also allow the system 700 to evaluate treatment options for future patients because if a treatment is historically shown to be problematic for any one or more reasons (e.g., difficulty in achieving patient compliance, slow progress in addressing symptoms, expensive, lack of insurance payments, etc.) or shown to be particularly effective for any one or more reasons (e.g., drug dose sizes decline over time, use of the drug is reduced or is eventually eliminated, post-operative recovery time decreases if the drug is used during surgery, etc.), the system 700 can be more likely (for particularly effective treatments) or less likely (for problematic treatments) to recommend the treatment for future patients.
Because the system 700 can be configured to simultaneously and continuously receive information regarding multiple patients from multiple drug administration devices 500, the system 700 can repeatedly analyze received data to help determine efficacy of a particular patient's treatment plan that includes use of the same type of drug administration device 500 as other patients and/or use of the same drug as other patients. The system 700 can thus determine that a particular patient's treatment plan should be modified based on another set of patients' data indicating low or high effectiveness for that type of drug administration device 500 and/or that drug. In other words, the system 700 can learn from other patients' experiences that the present patient's treatment could benefit from a modification, e.g., use a different type of drug administration device 500 that has a lower failure rate and/or a higher compliance rate, prescribe a different drug, increase or decrease dose frequency, etc. The system 700 can be configured to suggest the modification of the patient's treatment plan to a user, e.g., the patient, the patient's surgeon (and/or other medical professional), the patient's care provider, etc., by providing an alert (e.g., email message, text message, instant message, phone call, etc.) to the user indicating that modification of the patient's treatment plan is recommended. The user can review the modification, e.g., by logging onto the system 700 and/or other computer system in communication therewith, and determine whether to modify the patient's treatment plan. Alternatively, the system 700 can be configured to automatically modify the patient's treatment plan and inform the user via an alert as to the modified treatment plan. Usually, a medical professional would review a modification to check its appropriateness for the particular patient before the system 700 automatically modifies the patient's treatment plan and informs the patient, and/or other users as appropriate, of the change.
The artificial intelligence and machine learning system configured within the system 700 can include data processing components, each associated with a data processor, to monitor the effectiveness of the drug that is delivered via the drug administration device 500 (and/or additional drug administration device(s) 500 and/or drug housing(s) 630). In at least some embodiments, the system 700 can be configured to process the drug administration device usage and drug delivery data that has been aggregated with the clinical outcome data to determine how well the drug provides a therapeutic benefit and if the drug causes the patient to experience any side effects which may be reported via the clinical outcome data, including post-operative data. For example, the system 700 may determine a correlation between a particular drug (or a particular drug delivery schedule) and self-reported and/or sensed symptoms of nausea. The system 700 may further process data associated with an individual patient's medical history to determine a suitable dosage or delivery schedule which is less likely to cause nausea. In this way, new drugs or drug delivery regimens can be determined which produce a desired clinical outcome for a patient population. For another example, the system 700 may determine that patients receiving a different drug than the drug delivered to the patient did not experience a side effect experience by the patient receiving the drug and/or experienced the side effect less severely than the patient receiving the drug. The system 700 may thus determine that the drug received by the other patients would be a good alternative to suggest for the patient receiving the drug in an effort to stop the patient from experiencing the side effect or to reduce the side effect's severity.
In some embodiments, the system 700 can be configured to electronically transmit an instruction, which is based on the system's analysis of previously received data, to the drug administration device 500. The drug administration device 500 can be configured to execute the received instruction on board the drug administration device 500 to change at least one aspect of the device's/housing's functionality. The system 700 can thus be configured to remotely control the drug administration device 500.
For example, the instruction from the system 700 can include a request for the drug administration device 500 to alter the predetermined schedule at which data sensed by the one or more sensors is transmitted to the system 700 in embodiments in which the predetermined schedule is programmed into the memory 97 of the drug administration device 500. A doctor or other medical professional reviewing information about the drug administration device 500 gathered by the system 700 may desire more frequently sensed information to facilitate the doctor's or other medical professional's analysis of the patient's treatment plan, including during execution thereof such as during performance of a surgical procedure, and thus input a request to the system 700 for the system 700 to update the drug administration device's stored predetermined schedule.
For another example, the instruction from the system 700 can include a request for the drug administration device 500 to alter a function of drug delivery, such as the delivery schedule of the drug, a rate of drug injection, and a dosage of the delivered doses. A doctor or other medical professional reviewing information about the drug administration device 500 gathered by the system 700 may desire the altered function of drug delivery based on the information review. More particularly, an algorithm stored in the memory 97 of the drug administration device 500 can be executable on board by the processor 96 to administer a dose of the drug to a patient. The algorithm is stored in the form of one or more sets of pluralities of data points defining and/or representing instructions, notifications, signals, etc. to control functions of the device and administration of the drug. Data received by the drug administration device 500, e.g., as pluralities of data points via a communications interface thereof, is used, e.g., by the processor 96, to change at least one variable parameter of the algorithm based on the received instruction identifying the parameter to change and the parameter's updated value. The at least one variable parameter is among the algorithm's data points, e.g., are included in instructions for drug delivery, and are thus each able to be changed by changing one or more of the stored pluralities of data points of the algorithm. After the at least one variable parameter has been changed, subsequent execution of the algorithm administers another dose of the drug according to the changed algorithm. As such, drug delivery over time can be remotely managed for a patient, e.g., by a medical professional providing input for the drug delivery change to the system 700, to increase the beneficial results of the drug. Changing the at least one variable parameter and/or administration of the one or more doses themselves is automated to improve patient outcomes. Thus, the system 700 can be configured to facilitate personalized medicine based on the patient to provide a smart system for drug delivery.
The artificial intelligence and machine learning system configured within the system 700 can include data processing components configured to receive financial data that is associated with the costs of providing medical care to a patient. The received financial data can be used in a cost-benefit analysis for various drugs or therapeutic regimens which may be prescribed for a particular patient. The financial data includes payer, insurance, and/or hospital cost data, which when analyzed in regard to drug administration device usage and drug delivery data and the clinical outcome data, may provide insights as to lower cost alternatives of drugs which yield substantially the same clinical outcomes as the drug. For example, a particular drug may be associated with a lower insurance reimbursement rate and/or a lower hospital cost than another drug, where each of the drugs were used to treat the same medical issue (e.g., blood pressure, asthma, pain, etc.) and each had substantially similar clinical outcomes associated therewith. The drug with the higher insurance reimbursement rate and/or higher hospital cost rate may therefore be identified by the system 700 as a more financially sound option for a patient currently receiving (or planned to receive) the other drug as part of the patient's treatment plan. A person skilled in the art will appreciate that clinical outcomes may not be precisely the same but nevertheless be considered to be substantially the same as one another for any number of reasons, such as due to statistical standard deviation.
The system 700 can be configured to use the aggregated data to perform predictive modeling of drug delivery conformance and resulting clinical outcomes for a particular patient based on hypothetical parameters that can be provided to the system 700 by the patient's doctor and/or other care provider. The artificial intelligence and machine learning system configured within the system 700 can include data processing components configured to implement a machine learning process trained to generate a predictive model capable of receiving input parameters associated with the drug administration device usage or drug delivery data and to predict clinical outcomes based on the inputs. Once trained during a training phase of the machine learning process, the predictive model can be deployed as a trained prediction model within the system 700 and can be accessed via a user interface such as a web-based application configured on a web browser of a computer system at a medical facility 706 or via a user interface such as an app configured on a smart phone or other mobile computing device at a mobile location 710. The interface to the trained prediction model can allow a user to input data parameters for a particular patient associated with a particular treatment. The input parameters can include any one or more of, for example, parameters related to a drug delivery schedule, a drug dosage, a drug type, a drug administration device type, and the like. The trained prediction model can process the inputs and provide the user with a predicted clinical outcome, a predicted side effect, and/or other predicted behavioral or physiological changes that are predicted to become symptomatic for the particular patient based on the inputs. In this way, the system 700 may improve the ability of the physician or other care provider to assess various drug delivery schedules and alternate configurations of the drug administration device 500 in a controlled, low-risk manner before administering a new treatment regimen to the patient.
The system 700 can be configured to receive data transmitted from the drug administration device 500 and to process the data in regard to data and metadata that is associated with a medical professional's summary of a patient's treatment over time as recorded in the patient's medical history file. The system 700 can be configured to receive the physician summary data or metadata from a hospital information system as the physician summary data is entered into the patient's medical history file, such as from a cloud-based system such as the cloud 1004 of
Receiving physician summary data as it is recorded in the patient's medical history file allows the system 700 to immediately generate notifications as soon as non-compliant conditions are determined, such as a patient's allergy to a drug, adverse drug interactions, etc. The notifications can be generated as alerts or alarms which can be transmitted to one or more computer systems to inform a patient, the patient's doctor, and/or other appropriate medical professional that the patient is experiencing a non-compliance issue or other medical situation which requires immediate attention. The notification may enable the doctor and/or appropriate medical professional to rapidly instigate action to alleviate or reduce the non-compliant situation.
In at least some embodiments, the system 700 can include one or more data filters which can be applied to the physician summary data that has been aggregated with the data transmitted from the drug administration device 500. The data filters can include, for example, filters to parse the aggregated data on the basis of geographic region or ethnicity so that significant trends associated with patients included in the filtered data can be determined.
The system 700 can be configured to receive data transmitted from the drug administration device 500, and to process the data automatically and in real-time or near real-time to determine a complaint associated with the drug administration device 500. The system 700 can process received device usage data to determine a malfunction of the drug administration device 500 and, based on the malfunction, can generate a complaint. For example, device usage data received from the drug administration device 100 of
The system 700 can be configured to generate a malfunction report that is pre-populated with patient-specific device data describing the configuration of the malfunctioning drug administration device. In this way, the system 700 can assist diagnosing quality assurance issues for the drug administration device while ensuring that the patient is able to maintain their prescribed drug delivery schedule using a functioning drug administration device which may be provided as a replacement to the malfunctioning drug administration device.
The system 700 can be configured to respond to requests for additional data that are received from a remote location, such as the mobile location 710 of
The system 700 can be configured to aggregate data that is received from the drug administration device 500 with clinical outcome data to detect irregular treatment conditions for a particular treatment that has been prescribed to be performed using a particular configuration of the drug administration device 500. For example, the irregular treatment conditions include irregular dosage events, un-prescribed dosage timing intervals, and indicators of negative clinical outcomes, which can include post-operative outcomes as mentioned above. The system 700 can utilize the aggregated data to identify when the particular treatment is being performed outside of the prescribed or expected treatment parameters and can generate suggestions which are likely to improve the clinical outcome experienced by the patient. The generated suggestions can include action(s) to be performed when the system 700 determines that the irregular treatment conditions are associated with better than expected clinical outcomes. For example, if the system 700 determines that a patient's irregular treatment conditions result in an improved clinical outcome, the system 700 can mark the improved clinical outcome in a database and can initiate a search of data that may support or refute the unexpected improvement in the clinical outcome. The system 700 can be configured to analyze the search results, for example using natural language processing. If the system 700 determines that the irregular treatment conditions support the improved clinical outcome, the system 700 can forward the search results to pre-determined personnel for further consideration to include aspects of the irregular treatment conditions as a modification to the particular treatment or the particular configuration of the drug administration device 500.
When the system 700 determines that the irregular treatment conditions are associated with worse than expected clinical outcomes, the system's generated suggestions can include action(s) to be performed. For example, if the system 700 determines that a patient's irregular treatment conditions result in a worse or negative clinical outcome, the system 700 can generate a notification to the patient and/or to the patient's medical professional(s) informing each of them that an improved treatment or an improved configuration of the drug administration device 500 is available which may result in expected or improved clinical outcomes. For example, the notification may suggest to change the dosage intervals from, e.g., once per day to twice per day. Additionally, the notification can include various means or affordances to facilitate a conversation between the patient and his/her care provider in regard to the irregular treatment conditions and the resulting negative clinical outcomes. The notification to the patient's medical care professional can include details of the originally prescribed treatment and the corresponding configuration of the drug administration device 500 for the particular treatment. The notification to the patient's medical care professional can also include the expected clinical outcomes for the particular treatment that was originally prescribed.
Stimuli Responsive Drug Administration
As discussed herein, data gathered by one or more sensors of a drug administration device and/or one or more other sensors, such as sensor(s) in communication with a surgical hub or other computer system in communication with a drug administration device, can be used in analyzing clinical outcomes (including post-operative outcomes) and/or in controlling drug administration to a patient from a drug administration device. As also discussed above, sensor data may also be useful in machine learning regarding analysis of clinical outcomes and the control of drug administration. In at least some embodiments, the patient can have surgery planned or can have had surgery. In such cases, the clinical outcome analysis can include post-operative outcome analysis, in which the sensor data may help inform analysis the drug's effectiveness and/or the surgery's effectiveness, and/or the drug administration to the patient can be controlled before, during, and/or after surgery, in which case the sensor data may help inform when to deliver a drug from the drug administration device to the patient to help maximize effectiveness of the drug and/or the patient's overall treatment.
For example, in an oncological context, at least one drug administration device can be configured to deliver at least one drug including, for example, one or more of a chemotherapy drug, a nausea control drug, and a pain relief drug. The at least one drug can be used in combination with surgical intervention. Data gathered by one or more sensors can be used in analyzing clinical outcomes (including post-operative outcomes) to help improve the patient's (and/or other patients' outcomes via machine learning) and/or can be used in controlling administration of the at least one drug to the patient from the at least one drug administration device. Considering sensed data and information regarding the patient's surgery as gathered by sensor(s) and/or as input to a computer system by a medical professional, the best combination of surgery and drug administration can be learned over time for both the best outcome as well as the least negative impact on patient quality of life. Considering sensed data and information regarding the patient's surgery in contexts other than an oncological context can be similarly beneficial, such as in a bariatric surgery context, a cardiac context, a neurological context, etc.
Various conditions can be sensed by sensors, as discussed above, and used in analyzing clinical outcomes and/or controlling drug administration. For example, pH level may be beneficial to sense since certain drugs can be less effective if the pH level is above or below a certain level, and thus it may be beneficial to delay administering the drug until the pH level has returned to or is in a desired range, or to enhance activation to compensate for sub-optimal conditions. For another example, a biomarker is generally a naturally occurring molecule, gene, or other characteristic which provides an indicator as to a state of a particular pathological or physiological process or disease. Various sensors are configured to sense biomarkers, such as with microfluidics, and in various forms, such as skin patches. For yet another example, glutathione levels are of particular interest for chemotherapy drugs, as elevated levels of glutathione in cells can have the effect of protecting cells from the chemotherapy drugs. Thus, sensing glutathione levels and delaying activation until glutathione levels are reduced to below an acceptable threshold level, or enhancing the extent of activation to compensate for the increased protection of cells by glutathione, may be beneficial. For another example, skin thickness and subcutaneous thickness measurements can be used to ensure that a drug and/or an activator thereof, such as by an energy source, penetrates to sufficient depth. For still another example, various conditions configured to be sensed and relating to blood circulation, e.g., blood oxygen level, blood pressure, heart rate, and metabolic rate, can influence the efficacy and safety of a drug, and thus adjustment of delivery according to a value of one or more of the sensed conditions relating to blood circulation may enhance efficacy and safety. For another example, the sensed condition can include an external condition including one or more of a geographical location, ambient temperature, pressure, and ultraviolet radiation level. Drug delivery being responsive to the external condition may ensure that external condition(s) indicating the user's readiness to receive the drug are taken into consideration to optimize the timing or extent of drug delivery. For yet another example, environmental conditions such as temperature can impact on the efficacy or safety of a drug, and thus it may be advantageous to adjust administration accordingly, e.g., certain drugs can cause elevated side effects at high temperatures, and thus it may be beneficial to delay or reduce the extent of administration in such circumstances. For still another example, the sensed condition can include subcutaneous tissue thickness. The drug administration device and/or a separate, external computer system can be configured to adjust a drug administration device's discharge nozzle advance depth based on the sensed subcutaneous tissue thickness. This adjustment may ensure that the drug is administered to the patient into tissue where the drug will be more readily absorbed, injection site leakage can be minimized, back flow of the drug can be prevented, and a risk of tissue damage and scarring resulting from the drug administration can be reduced.
A drug administration device and/or an external, separate computer system can be configured to determine, based on one or more sensed conditions, whether a likelihood of side effects associated with a drug deliverable from the drug administration device has increased, and, if it is determined that the likelihood of side effects has increased, adjust the drug dosing scheme to reduce the dosage of the drug to be administered from the drug administration device and/or adjust activation means configured to provide local activation to reduce local activation of the drug (discussed further below). This adjustment of the drug dosing scheme may minimize a risk of increased side effects under conditions which cause the side effects to be enhanced, such as high body or ambient temperature, by reducing the amount of drug that is administered, and/or by reducing the activation of the drug since the active form of the drug may be associated with the side effects. The adjustment of activation may include stopping activation altogether, or reducing the extent to which activation occurs, such as by reducing energy provided by an energy source. The drug administration device can include a device indicator, as discussed above, and the drug administration device can be configured to activate the device indicator if it is determined that the likelihood of side effects is increased. This notification may be used to alert a user to manually change usage of the drug administration device, such as to cease operation of the drug administration device, to alter a parameter of the drug administration device such as the discharge nozzle advance depth when the drug administration device includes an advanceable discharge nozzle, etc. Such changes can instead be automatically caused by the drug administration device and/or an external, separate computer system, which may help ensure that the changes are made in a timely fashion or at all.
In at least some embodiments, a drug administered from drug administration device to a patient can be configured to be locally activates at a target location in the patient after the drug has been administered to the patient. The local activation can be responsive to gathered sensor data. In other words, sensed condition(s) can be used to control when the drug is locally activated.
Local activation may allow an inactive form of a drug, or a drug with attenuated activity, to be administered systemically to a patient. Such a drug is configured to only be made active at a target location, where its therapeutic effect is desired, in the patient. The target location is typically a volume rather than a specific point. The location in the patient can include locations on a surface of the patient, such as the skin. Harmful effects that may be associated with the active form of the drug on unintended, or off-target, locations in the patient may be minimized by locally activating the drug at only the target location, and/or local activation may improve efficacy of the drug since the drug is only activated at the target location within the patient's body where and when the drug's therapeutic effect is desired, thus concentrating the drug's benefit. Consequently, the dose of the drug required may also be reduced. By making the local activation responsive to the sensed data, e.g., patient parameter, sensed environmental condition, etc., efficacy and safety may be further improved, as the drug is only activated when the drug administration device (and/or a computer system external to and separate from the drug administration device) determines that sensed one or more conditions are suitable or appropriate, or that sufficient time has elapsed such that the drug will have localized at the desired target location within the patient. Suitable/appropriate conditions and elapse of sufficient time lapse can be variables learned over time via machine learning. The local activation being responsive to the sensed condition(s) may improve compliance, as the drug administration device (and/or computer system controlling drug administration from the drug administration device) controls when the drug becomes active in accordance with suitable or appropriate conditions, rather than being entirely dependent on when the drug is administered by a user. This activation may be particularly important for applications outside of a clinical setting, in which the drug may be administered by the patient themselves, instead of by a medical professional, and drug administration may be done at a sub-optimal time and/or under sub-optimal conditions. Certain sub-optimal conditions (e.g., improper temperature of the drug, improper pH level of the drug, elevated glutathione level, too low blood pressure, etc.) may result in the drug, in its usual dosage, not being effective, and/or may lead to increased side effects. Thus, it is beneficial if local activation of the drug is responsive to these suitable or appropriate conditions.
The local activation being responsive to the patient parameter and the external stimulus can include that the activation occurs when the sensed data satisfies a predetermined criterion. The predetermined criterion can be that, for each of one or more sensed conditions, the condition exceeds or falls below a threshold level, or alternatively that the condition satisfies a predetermined mathematical relationship. An extent of the local activation can also be responsive to the sensed condition.
Sensed data can permit identification and/or quantification of a condition that can influence a localization time, efficacy, and/or side effects associated with the drug. For example, ambient temperature can influence viscosity of the drug, which in turn influences a time required for the drug to reach, or localize, at the target location in the patient. The drug may become less viscous if the drug is too warm (e.g., if the drug's temperature is above a predetermined threshold temperature or is outside a predefined safe range of temperatures), and can in turn travel more freely in the patient, at greater speed, to the target location. Increased temperature of the drug can also lead to increased heart rate and vasodilation, thereby leading to faster localization of the drug at the target site. The drug's temperature settles to the environmental temperature, so the environmental temperature can be indicative of the drug's temperature. Consequently, the local activation being responsive to such an external stimulus may improve efficacy and/or minimize side effects.
A drug administration device can include an energy source configured to provide energy to locally activate the drug at the target location in the patient. This provision of energy can have the effect that the drug can be activated at a precise location by targeted application of energy to a patient. The energy source can be configured to target not only a surface location on the patient, but also be set to a desired penetration depth, to provide a precise target location, which as mentioned above is typically a volume rather than a specific point, within the patient. The energy source can include multiple energy sources of different types to provide different penetration and activation characteristics.
The drug can be configured to interact with the energy provided by the energy source to assume its active form. Alternatively, an activation device implanted in the patient can be configured to trigger activation of the drug at the target location in response to energy provided by the energy source.
An amount of energy provided by the energy source can be provided based on the sensed data. In this way, an extent, and thus a rate, of drug activation may be more precisely controlled to improve the drug's efficacy and safety in response to sensed condition(s). For example, it may be desirable to more gradually activate the drug by providing a smaller amount of energy over a longer period of time, if sensed condition(s) are such that the drug cannot be taken up (e.g., absorbed, metabolized, etc.) by the patient at the target location as quickly as normal. Thus, a further benefit of the gradual activation may be that less of the drug is wasted.
The energy source can include one or more of a light source, an ultra-sound source, an electro-magnetic field source, and a radioactive material.
The energy source can be configured to interact with the drug or an implanted device, as mentioned above. A combination of multiple types of energy sources can be provided to provide variable penetration characteristics. For example, energy sources capable of providing electromagnetic fields of different wavelengths can be used. Where appropriate, a frequency of the energy source can be adjusted by the drug administration device and/or a computer system external to and separate from the drug administration device to control a rate and amount of energy delivery, as well as the penetration depth. Each energy source can be provided as an external, separate unit to the drug administration device or as an integral part of the drug administration device.
The drug administration device can be configured to administer a chemical activation agent to the target location in the patient to locally activate the drug that was delivered to the patient using the drug administration device. While this chemical activation agent administration requires the drug administration device to be capable of administering both a drug and the chemical activation agent, which may require an additional holder for the chemical activation agent and an additional associated dispensing mechanism, such a drug administration device advantageously does not require an energy source to activate the drug, and thus may be of simpler construction in certain respects. The additional holder for the chemical activation agent can be arranged in series with the drug holder, such that the same dispensing mechanism can be used for dispensing both the drug and the chemical activation agent. Alternatively, the holders can be arranged in parallel with independent dispensing mechanisms.
In other embodiments, a first drug administration device can be configured to deliver the drug, and a second drug administration device can be configured to deliver the chemical activation agent.
The chemical activation agent can be administered to the target location before or after the drug is administered to the patient by the drug administration device. For example, a chemical activation agent can be administered into a tumor before or after a chemotherapy drug, in an inactive form or with attenuated activity, is systemically delivered to the patient. The chemical activation agent can be configured to remain in the tumor so that the chemotherapy drug is only activated at the target location by a chemical reaction with, or a chemical reaction triggered by, the chemical activation agent.
The patient sensor 1220 is discrete from the autoinjector 1210 and is connected, by a wire or wirelessly, to the autoinjector 1210, in order to communicate data. Alternatively, the patient sensor 1220 can be disposed on a surface of the autoinjector 1210 and arranged in close proximity to the patient's skin when the drug administration device 1210 is positioned for administration of the drug to the patient.
The skin is pricked by a user to release a small quantity of blood, and the patient sensor 1220 is configured to measure a blood glucose level in a sample of the blood disposed on the sensor 1220. An energy source 1240, in the form of an electro-magnetic field source in this illustrated embodiment, is arranged on a housing of the autoinjector 1210 to direct an electromagnetic field towards a target location in the patient in order to activate the drug, which is insulin in this illustrated embodiment, after the drug has been administered, at the target location in the patient.
The external stimulus sensor 1230 in this illustrated embodiment is in the form of a temperature sensor, is disposed at a position external to the patient, and is configured to measure ambient temperature. A frequency of the electromagnetic field delivered by the energy source 1240 is configured to be altered by the drug administration device 1210, e.g., to change the amount of energy delivered, in response to the measured blood glucose level and the measured ambient temperature. In particular, the measured values are compared with a look-up table to determine the frequency to be used. The frequency determines penetration of the energy and the extent of activation.
In an alternative embodiment, the autoinjector 1210 can be used to administer a chemotherapy drug, the patient sensor 1220 can be a blood pressure meter, and the external stimulus sensor 1230 can be used to measure ambient temperature. Data collected by the patient sensor 1220 and the external stimulus sensor 1230 can be transmitted to the autoinjector 1210 via wires or wirelessly. A processor on board the autoinjector 1210 (and/or a computer system to which the autoinjector 1210 communicates the sensed blood pressure and temperature data) can be used to calculate, based on the sensed blood pressure data and the measured ambient temperature, how long to delay initiating activation of the chemotherapy drug after the drug has been administered to the patient. Such a calculation may be based on an algorithm, or alternatively derived from a look-up table. The delay can be calculated such that the activation, provided by the energy source 1240 in the form of a light source, directed at the tumor site coincides with the localization time for the drug to reach the target location in the patient. Since the drug is carried to the target site in the blood stream, the localization time is dependent on blood pressure, as well as ambient temperature, which affects various physiological parameters of the patient and characteristics of the drug itself, such as viscosity.
