Description

[Technical field]

[0001] The embodiments described herein relate to devices for administering and / or delivering a drug. The present disclosure further relates to systems in which the devices may be used, and methods of administration, as well as further methods associated with the systems. [Background technology]

[0002] Pharmaceutical products (including large molecule and small molecule pharmaceuticals, hereafter "drugs") are administered to patients in a variety of different ways for the treatment of specific medical indications. Regardless of the mode of administration, care must be taken when administering the drug to avoid adverse effects to the patient. For example, care must be taken not to administer more than a safe amount of drug to the patient. This requires consideration of the amount of the dose given and the time frame in which the dose is delivered, sometimes in relation to previous doses or doses of other drugs. Additionally, care must be taken not to inadvertently administer the wrong drug to the patient, or a drug that has deteriorated due to its age or storage conditions. All of these considerations may be communicated in guidance associated with a particular drug or drug combination. However, this guidance is not always followed correctly, for example, due to mistakes such as human error. This can lead to adverse effects to the patient or result in inappropriate drug administration, for example, an insufficient or excessive volume of drug administered for a particular medical indication.

[0003] Furthermore, while consideration of the patient's circumstances during drug administration helps to avoid adverse reactions beyond the initial dose of the drug caused by various factors, these circumstances may be difficult to assess at all or difficult to assess in a timely manner, and thus safe drug administration and individualized patient care may be adversely affected.

[0004] Regarding how a drug is administered to a patient, there are various dosage forms that can be used. For example, these dosage forms can include parenteral, inhaled, oral, ophthalmic, nasal, topical, and suppository forms of one or more drugs.

[0005] Dosage forms may be administered directly to a patient via a drug administration device. There are many different types of drug administration devices commonly available for the delivery of various dosage forms, including syringes, injection devices (e.g., autoinjectors, jet injectors, and infusion pumps), nasal spray devices, and inhalers.

[0006] It may be desirable to monitor compliance with guidelines associated with drugs administered to patients in various dosage forms. This may provide assurance that correct procedures are being followed and may avoid the adoption of incorrect and potentially dangerous approaches. Furthermore, this may allow for optimization of the administration of drugs to patients. Summary of the Invention [Means for solving the problem]

The size and shape of the systems and devices, and their components, may depend on at least the size and shape of the components with which the systems and devices are used.

[0029] Examples of various types of drug administration devices, namely an autoinjector 100, an infusion pump 200, an inhaler 300, and a nasal spray device 400, are described below with reference to the above referenced figures.

[0030] Autoinjector FIG. 1 is a schematic, exemplary diagram of a first type of drug delivery device, i.e. an injection device, in this example an autoinjector 100, usable in the embodiments described herein. The autoinjector 100 comprises a drug holder 110 for holding a drug to be dispensed, and a dispensing mechanism 120 configured to dispense the drug from the drug holder 110 so that the drug can be administered to a patient. The drug holder 110 is typically in the form of a container for containing the drug, for example the drug holder 110 may be provided in the form of a syringe or a vial, or any other suitable container capable of holding a drug. The autoinjector 100 comprises an ejection nozzle 122, e.g. a needle of a syringe, provided at the distal end of the drug holder 110. The dispensing mechanism 120 comprises a drive element 124, which itself may also comprise a piston and / or a piston rod, as well as a drive mechanism 126. The dispensing mechanism 120 is located proximal to the end of the medication holder 110 and toward the proximal end of the autoinjector 100 .

[0031] The autoinjector 100 comprises a housing 130 that houses within its body the drug holder 110, the drive element 124, and the drive mechanism 126, as well as an ejection nozzle 122 that is typically fully contained within the housing prior to injection, but which extends from the housing 130 to deliver the drug during an injection sequence. The dispensing mechanism 120 is positioned such that the drive element 124 is advanced through the drug holder 110 to dispense the drug through the ejection nozzle 122, thereby enabling the autoinjector to administer the drug held within the drug holder 110 to a patient. In some cases, a user may manually advance the drive element 124 through the drug holder 110. In other cases, the drive mechanism 126 may include a stored energy source 127 that advances the drive element 124 without user assistance. The stored energy source 127 may include a resilient biasing member, such as a spring, or pressurized gas, or an electronically powered motor and / or gearbox.

[0032] The autoinjector 100 includes a dispensing mechanism protection mechanism 140. The dispensing mechanism protection mechanism 140 typically has two functions. First, the dispensing mechanism protection mechanism 140 may function to prevent access to the discharge nozzle 122 before and after injection. Second, the autoinjector 100 may function such that the dispensing mechanism 120 may be actuated when the dispensing mechanism protection mechanism 140 is armed, e.g., moved to an unlocked position.

[0033] The protection mechanism 140 covers at least a portion of the discharge nozzle 122 when the medication holder 110 is in a retracted position proximally within the housing 130. This is to prevent contact between the discharge nozzle 122 and a user. Alternatively or additionally, the protection mechanism 140 is configured to retract itself proximally to expose the discharge nozzle 122, so that the discharge nozzle 122 can be contacted by a patient. The protection mechanism 140 comprises a shield member 141 and a 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. When a user applies force to the shield member 141 against the action of the return spring 142 to overcome the bias of the return spring 142, the shield member 141 retracts within the housing 130, thereby exposing the discharge nozzle 122. The protection mechanism 140 may alternatively or additionally comprise an extension mechanism (not shown) for extending the discharge nozzle 122 beyond the housing 130, and may further comprise a retraction mechanism (not shown) for retracting the discharge nozzle 122 into the housing 130. The protection mechanism 140 may alternatively or additionally comprise a housing cap and / or a discharge nozzle boot that may be attached to the autoinjector 100. Removal of the housing cap typically also removes the discharge nozzle boot from the discharge nozzle 122.

[0034] The autoinjector 100 also includes a trigger 150. The trigger 150 comprises a trigger button 151 located on an exterior surface of the housing 130 so as to be accessible by a user of the autoinjector 100. When the trigger 150 is pressed by the user, the trigger 150 acts to release the drive mechanism 126 such that the medicament is then expelled from the medicament holder 110 via the drive element 124 and the discharge nozzle 122.

[0035] Trigger 150 may also cooperate with shield member 141 in a manner that prevents trigger 150 from being actuated until shield member 141 is retracted proximally sufficiently into an unlocked position within housing 130, for example, by pressing a distal end of shield member 141 against the patient's skin. Once this is done, autoinjector 100 is actuated such that trigger 150 is unlocked, trigger 150 can be pressed, and an injection and / or drug delivery sequence can then be initiated. Alternatively, retracting shield member 141 proximally into housing 130 alone may act to actuate drive mechanism 126 and initiate an injection and / or drug delivery sequence. In this manner, autoinjector 100 has a device actuation prevention mechanism that prevents drug dispensing, for example, by preventing accidental release of dispensing mechanism 120 and / or accidental actuation of trigger 150.

[0036] Although the foregoing description relates to one example of an autoinjector, this example is presented purely for purposes of illustration and the invention is not limited to such autoinjectors. Those skilled in the art will appreciate that various modifications to the autoinjector described may be implemented within the scope of the present disclosure.

[0037] The autoinjector of the present disclosure may be used to administer any of a variety of drugs, such as any of epinephrine, Rebif, Enbrel, Aranesp, atropine, pralidoxime chloride, and diazepam.

[0038] Infusion pump In other situations, patients may require precise continuous delivery of medication, or regular or frequent delivery of medication at set periodic intervals. Infusion pumps can provide such controlled drug infusion by facilitating administration of medication at precise rates that keep drug concentrations within therapeutic limits without the need for frequent attention by a medical professional or the patient.

[0039] 2 is a schematic, exemplary diagram of a second type of drug delivery device, an infusion pump 200, usable in the embodiments described herein. The infusion pump 200 comprises a drug holder 210 in the form of a reservoir for containing the drug to be delivered, and a dispensing mechanism 220 comprising a pump 216 adapted to dispense the drug contained in the reservoir so that the drug can be delivered to the patient. These components of the infusion pump are located in a housing 230. The dispensing mechanism 220 further comprises an infusion line 212. The drug is delivered from the reservoir via the infusion line 212, which may take the form of a cannula, upon actuation of the pump 216. The pump 216 may take the form of an elastomeric pump, a peristaltic pump, an osmotic pump, or a motor-controlled piston in a syringe. Typically, the drug is delivered intravenously, but subcutaneous, arterial, and epidural injections may also be used.

[0040] The infusion pumps of the present disclosure may be used to administer any of a variety of drugs, such as any of insulin, atropine sulfate, avibactam sodium, bendamustine hydrochloride, carboplatin, daptomycin, epinephrine, levetiracetam, oxaliplatin, paclitaxel, pantoprazole sodium, treprostinil, vasopressin, voriconazole, and zoledronic acid.

[0041] Infusion pump 200 further comprises a processor 296, as well as control circuitry, e.g., a memory 297, and a user interface 280, which together provide a triggering mechanism and / or a dose selector for pump 200. User interface 280 may be implemented by a display screen located on housing 230 of infusion pump 200. The control circuitry and user interface 280 may be located within or external to housing 230 and communicate with pump 216 via a wired or wireless interface to control its operation.

[0042] The operation of the pump 216 is controlled by a processor 296, which communicates with the pump 216 to control the operation of the pump. The processor 296 may be programmed by a user (e.g., a patient or a medical professional) via a user interface 280. This allows the infusion pump 200 to deliver medication to the patient in a controlled manner. The user may input parameters such as the infusion duration and delivery rate. The delivery rate may be set by the user to a constant infusion rate or as set intervals, typically within preprogrammed limits, for periodic delivery. The programmed parameters for controlling the pump 216 are stored in and retrieved from a memory 297, which communicates with the processor 296. The user interface 280 may take the form of a touch screen or a keypad.

[0043] Power supply 295 provides power to pump 216 and may take the form of an energy source integral to pump 216 and / or a mechanism for connecting pump 216 to an external power source.

[0044] Infusion pump 200 can take a variety of different physical forms depending on its intended use. Infusion pump 200 may be a fixed, non-portable device, for example, for use at a patient's bedside, or it may be an ambulatory infusion pump designed to be portable or wearable. An integrated power supply 295 is particularly beneficial for ambulatory infusion pumps.

[0045] Although the foregoing description relates to one example of an infusion pump, this example is provided purely for illustrative purposes. The present disclosure is not limited to such infusion pumps. Those skilled in the art will appreciate that various modifications to the described infusion pumps may be implemented within the scope of the present disclosure. For example, the processor may be preprogrammed such that the infusion pump need not include a user interface.

[0046] inhaler Fig. 3 is a schematic diagram of a third type of drug administration device, namely an inhaler 300. The inhaler 300 comprises a drug holder 310 in the form of a canister. The drug holder 310 typically contains a drug in solution or suspension with a suitable carrier liquid. The inhaler 300 further comprises a dispensing mechanism 320 including a pressurized gas for pressurizing the drug holder 310, a valve 325 and a nozzle 321. The valve 325 forms the outlet of the drug holder 310. The valve 325 comprises a narrow opening 324 formed in the drug holder 310 and a movable element 326 that controls the opening 324. When the movable element 326 is in the rest position, the valve 325 is in a closed or non-actuated state in which the opening 324 is closed and the drug holder 310 is sealed. When the movable element 326 is actuated from the rest position to the actuated position, the valve 325 is actuated to an open state in which the opening 324 is open. Actuation of the movable element 326 from the rest position to the actuated position involves moving the movable element 326 into the drug holder 310. The movable element 326 is elastically biased to the rest position. In the open state of the valve 325, the pressurized gas pushes the drug, which is in a solution or suspension with a suitable liquid, out of the drug holder 310 at high speed through the opening 324. The high speed passage of the liquid through the narrow opening 324 causes the liquid to be atomized, i.e., converted from a bulk liquid into a mist of fine droplets of liquid and / or a gas cloud. The patient may inhale the mist of fine droplets and / or the gas cloud into the respiratory pathway. Thus, the inhaler 300 can deliver the drug held in the drug holder 310 into the patient's respiratory pathway.

[0047] The drug holder 310 is removably held within the housing 330 of the inhaler 300. A passageway 333 formed within the housing 330 connects a first opening 331 within the housing 330 and a second opening 332 within the housing 330. The drug holder 310 is received within the passageway 333. The drug holder 310 is slidably insertable within the passageway 333 through the first opening 331 of the housing 330. The second opening 332 of the housing 330 forms a mouthpiece 322 configured to be placed within the patient's mouth, or a nosepiece configured to be placed within the patient's nostrils, or a mask configured to be placed over the patient's mouth and nose. The drug holder 310, the first opening 331, and the passageway 333 are sized such that air can flow through the passageway 333 around the drug holder 310 between the first opening 331 and the second opening 332.

[0048] The inhaler 300 may include a dispensing mechanism protection mechanism 140 in the form of a cap (not shown) that may be fitted to the mouthpiece 322. The inhaler 300 further includes a trigger 350 including a valve actuation feature 355 configured to actuate the valve 325 when the trigger 350 is actuated. The valve actuation feature 355 is a protrusion of the housing 330 into the passageway 333. The medication holder 310 is slidably movable within the passageway 333 from a first position to a second position. In the first position, an end of the movable element 326 in a rest position abuts the valve actuation feature 355. In the second position, the medication holder 310 may be displaced towards the valve actuation feature 355 such that the valve actuation feature 355 moves the movable element 326 into the medication holder 310 to actuate the valve 325 to an open state. The user's hand provides the necessary force to move the medication 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 connected to the nozzle 321. The inlet 356 of the valve actuation feature 355 is sized and positioned to mate with 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 the nozzle 321 into the passageway 333. The nozzle 321 assists in the atomization of the bulk liquid into a mist of droplets and / or gas cloud.

[0049] The valve 325 provides a metering mechanism 370 that is configured to close the valve after a measured amount of liquid, and therefore the medication, 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, but the inhaler 300 may also include a dose selector 360 that is user operable to vary the defined amount of liquid.

[0050] Although the above description relates to one particular example of an inhaler, this example is purely illustrative. The description should not be considered as being limited to only such an inhaler. Those skilled in the art will appreciate that numerous other types of inhalers and nebulizers can be used with the present disclosure. For example, the drug can be in powder form, the drug can be in liquid form, or the drug can be atomized by other forms of dispensing mechanism 320, including ultrasonic vibrations, compressed gas, vibrating mesh, or a heat source.

[0051] The inhaler of the present disclosure may 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.

[0052] Nasal spray device FIG. 4 is a schematic diagram of a fourth type of drug delivery device, namely, a nasal spray device 400. The nasal spray device 400 is configured to release a drug into the patient's nose. The nasal spray device 400 includes a drug holder 402 configured to contain a drug therein for delivery from the device 400 to the patient. The drug holder 102 may have a variety of configurations, such as a bottle reservoir, a cartridge, a vial (as in this exemplary embodiment), a Blow-Fill-Seal (BFS) capsule, a blister pack, and the like. In one exemplary embodiment, the drug holder 402 is a vial. An exemplary vial is formed of one or more materials, such as glass, polymers, and the like. In some embodiments, the vial may be formed of glass. In other embodiments, the vial may be formed of one or more polymers. In still other embodiments, different portions of the vial may be formed of different materials. The exemplary vial may have a variety of features that facilitate sealing and storing a drug therein, as described herein and shown in the figures. However, one of ordinary skill in the art will recognize that the vial may include only some of these features and / or may include a variety of other features known in the art. The vials described herein are intended only to represent certain exemplary embodiments.

[0053] The opening 404 of the nasal spray device 400, through which the medication exits the nasal spray device 400, is formed in a dispensing head 406 of the nasal spray device 400 and in a tip 408 of the dispensing head 406. The tip 408 is configured to be inserted into a patient's nostril. In one exemplary embodiment, the tip 408 is configured to be inserted into a first nostril of the patient during a first phase of operation of the nasal spray device 400 and into a second nostril of the patient during a second phase of operation of the nasal spray device 400. The first and second phases of operation involve two separate actuations of the nasal spray device 400, a first actuation corresponding to a first dose of medication being delivered and a second actuation corresponding to a second dose of medication being delivered. In some embodiments, the nasal spray device 400 is configured to be actuated only once to deliver one nasal spray. In some embodiments, the nasal spray device 400 is configured to be actuated three or more times to deliver three or more nasal sprays, for example, four, five, six, seven, eight, nine, ten, etc.

[0054] The dispensing head 406 includes a depth guide 410 configured to contact the patient's skin between the patient's first and second nostrils such that the longitudinal axis of the dispensing head 406 is substantially aligned with the longitudinal axis of the nostril into which the tip 408 is inserted. Those skilled in the art will appreciate that due to any number of factors, such as manufacturing tolerances and sensitivity of measurement equipment, the longitudinal axes may not be precisely aligned, but may be considered substantially aligned.

[0055] In an exemplary embodiment, as in FIG. 4, the dispensing head 406 has a tapered shape, with the dispensing head 406 having a smaller diameter at its distal end than at its proximal end where the opening 404 is located. The opening 404 having a relatively smaller diameter facilitates spraying of the medicament from the opening 404, as will be understood by one of ordinary skill in the art. Located within the proximal portion of the tapered dispensing head 406 distal to the opening 404 is a spray chamber 412 through which the medicament is configured to pass before exiting the opening 404. As the medicament passes rapidly through the spray chamber 412, the spray chamber 412 facilitates the generation of a fine mist that exits through the opening 404 with a consistent spray turn. Arrows 414 in FIG. 4 indicate the path of travel of the medicament from the medicament holder 402 and out of the opening 404.

[0056] In some embodiments, the dispensing head 406 may include two tips 408, each having an opening 404 therein, such that the nasal spray device 400 is configured to deliver a dose of drug simultaneously into two nostrils in response to a single actuation.

[0057] The dispensing head 406 is configured to be pressed towards the medication holder 402, for example by a user depressing the depth guide 410, to actuate the nasal spray device 400. In other words, the dispensing head 406 is configured as an actuator that is actuated to expel the medication from the medication holder 402 and out of the nasal spray device 400. In one exemplary embodiment, the nasal spray device 400 is configured to be self-administered, such that the user who actuates the nasal spray device 400 is the patient who receives the medication from the nasal spray device 400, although another person may actuate the nasal spray device 400 for delivery to another person.

[0058] Actuation, e.g., pressing, of the dispensing head 406 is configured to force vent air into the drug holder 402, as shown by arrow 416 in FIG. 4. The air entering the drug holder 402 moves the drug within the drug holder through tube 418 and then into metering chamber 420, which moves the drug proximally through cannula 422, through spray chamber 412, and then out opening 404. In response to release of the dispensing head 406, e.g., when a user stops pressing downwardly on the dispensing head 406, a biasing spring 426 returns the dispensing head 406 to its default rest position to position the dispensing head 406 relative to the drug holder 402 for subsequent actuation and drug delivery.

[0059] Although the above description relates to one particular example of a nasal spray device, this example is purely illustrative. This description should not be considered as being limited to only such a nasal spray device. Those skilled in the art will appreciate that the nasal spray device 400 may include different features in different embodiments according to various requirements. For example, the nasal spray device 400 may lack a depth guide 410 and / or may include any one or more of a device indicator, a sensor, a communication interface, a processor, a memory, and a power source.

[0060] The nasal spray device of the present disclosure may be used to administer any of a variety of drugs, such as ketamine (e.g., Ketalar®), esketamine (e.g., Spravato®, Ketanest®, and Ketanest-S®), naloxone (e.g., Narcan®), and sumatriptan (e.g., Imitrex®).

[0061] Drug Delivery Devices As will be appreciated from the foregoing, various components of a drug delivery device are common to all such devices. These components form the essential components of a universal drug administration device. The drug administration device delivers a drug to a patient, the drug being provided within the drug administration device in a defined dosage form.

[0062] Figure 5A is a generalized schematic diagram of such a universal drug administration device 501, and Figure 5B is an exemplary embodiment of such a universal drug administration device 500. Examples of universal drug administration devices 500 include injection devices (e.g., autoinjectors, jet injectors, and infusion pumps), nasal spray devices, and inhalers.

[0063] As shown in Figure 5A, the drug administration device 501 in its general form includes features of a drug holder 10 and a dispensing mechanism 20. The drug holder 10 holds a drug in a dosage form to be administered. The dispensing mechanism 20 is configured to release the dosage form from the drug holder 10 so that the drug may be administered to a patient.

[0064] 5B shows a further universal drug administration device 500 including several additional features. Those skilled in the art will appreciate that these additional features are optional for different embodiments and may be utilized in a variety of different combinations such that additional features may be present or omitted from a given embodiment of a particular drug administration device depending on requirements such as the type of drug, the dosage form of the drug, the medical indication being treated with the drug, safety requirements, whether the device is powered, whether the device is portable, whether the device is used for self-administration, and many other requirements that will be appreciated by those skilled in the art. Similar to the universal device of FIG. 5A, the drug administration device 500 comprises a housing 30 that houses the drug holder 10 and the dispensing mechanism 20.

[0065] The device 500 comprises a trigger mechanism 50 for initiating the release of the drug from the drug holder 10 by the dispensing mechanism 20. The device 500 includes a metering / dispensing mechanism 70 feature that measures a set dose released from the drug holder 10 via the dispensing mechanism 20. In this manner, the drug dispensing device 500 may provide a known dose of a determined size. The device 500 comprises a dose selector 60 that allows a user to set a dose volume of the drug to be measured by the metering mechanism 70. The dose volume may be set to one particular value of a plurality of predetermined individual dose volumes or any value of a predetermined dose volume within a range of dose volumes.

[0066] The device 500 may comprise a device operation prevention mechanism 40 or 25, which when in a locked state prevents and / or stops the dispensing mechanism 20 from releasing the drug from the drug holder 10, and when in an unlocked state allows the dispensing mechanism 20 to release the drug dose from the drug holder 10. This may prevent accidental dispensing of the drug, e.g., to prevent dosing at the wrong time or to prevent inadvertent actuation. The device 500 also includes a dispensing mechanism protection mechanism 42, which prevents access to at least a portion of the dispensing mechanism 20, e.g., for safety reasons. The device operation prevention mechanism 40 and the dispensing mechanism protection mechanism 42 may be the same component.

[0067] The device 500 may include a device indicator 85 configured to present information regarding the status of the drug administration device and / or the drug contained therein. The device indicator 85 may be a visual indicator, such as a display screen, or an audio indicator. The device 500 includes a user interface 80 that may be configured to present information regarding the device 500 to a user of the device 500 and / or to allow the user to control the device 500. The device 500 includes a device sensor 92 configured to sense information related to the drug administration device and / or the drug contained therein, such as dosage form and device parameters. As an example, in an embodiment including a metering mechanism 70 and a dose selector 60, the embodiment may further include one or more device sensors 92 configured to sense one or more of a dose selected by a user using the dose selector 60, a dose metered by the metering mechanism 70, and a dose dispensed by the dispensing mechanism 20. Similarly, an environmental sensor 94 is provided that is configured to sense information regarding the environment in which the device 500 resides, such as the temperature of the environment, the temperature of the environment, location, and time. There may be a dedicated location sensor 98 configured to determine the geographic location of the device 500, for example via satellite positioning such as GPS. The device 500 also includes a communication interface 99 that may communicate data obtained from the various sensors regarding the device and / or medication to the outside world.

[0068] Optionally, the device 500 includes a power source 95 for delivering power to one or more electrical components of the device 500. The power source 95 can be a power source integral to the device 500 and / or a mechanism for connecting the device 500 to an external power source. The drug administration device 500 also includes a device computer system 90 including a processor 96 and memory 97 that are powered by the power source 95 and communicate with each other and, optionally, with other electrical and control components of the device 500, such as the environmental sensor 94, the position sensor 98, the device sensor 92, the communication interface 99, and / or the indicator 85. The processor 96 is configured to obtain data obtained from the environmental sensor 94, the device sensor 92, the communication interface 99, the position sensor 98, and / or the user interface 80, process it, and provide a data output, for example, to the indicator 85 and / or to the communication interface 99.

[0069] In some embodiments, the drug administration device 500 is sealed within packaging 35. The packaging 35 may further include a combination of a processor 96, memory 97, user interface 80, device indicators 85, device sensors 92, position sensors 98, and / or environmental sensors 94, as described herein, which may be located external to the housing of the device 500.

[0070] Those skilled in the art will appreciate that the universal drug administration device 500, comprising a drug holder 10 and a dispensing mechanism 20, may comprise the various optional features described above in a number of different combinations. Additionally, the drug administration device 500 may optionally include more than one drug holder 10 with more than one dispensing mechanism 20, such that each drug holder has its own associated dispensing mechanism 20.

[0071] Drug Form Traditionally, drug delivery devices utilize liquid dosage forms, however, it will be appreciated that other dosage forms may be utilized.

[0072] One such common dosage form is a tablet. Tablets can be formed from a combination of a drug and excipients that are compressed together. Other dosage forms are pastes, creams, powders, ear drops, and eye drops.

[0073] Further examples of drug dosage forms include skin patches, drug-eluting stents, and intrauterine devices. In these examples, the body of the device may be configured to include the drug and allow for the release of the drug under certain circumstances. For example, a skin patch may include a polymer composition containing the drug. The polymer composition allows the drug to diffuse from the polymer composition into the patient's skin. Drug-eluting stents and intrauterine devices may operate in a similar manner. In this way, patches, stents, and intrauterine devices may themselves be considered drug holders with associated dispensing mechanisms.

[0074] Any of these dosage forms may be configured to trigger drug release upon a specific condition. This may allow the drug to be released at a desired time or location after the dosage form is introduced into the patient. In particular, drug release may be triggered by an external stimulus. Additionally, these dosage forms may be contained within a housing, which may be a form of packaging, prior to administration. This housing may include some of the optional features described above that are utilized in the universal drug administration device 500.

[0075] A drug administered by the drug delivery device of the present disclosure can be any substance that, when consumed, causes a change in the physiology or psychology of an organism.

The memory 897 may include Read-Only Memory (ROM), Flash memory, one or more of various Random Access Memory (RAM) types (e.g., Static RAM (SRAM), Dynamic RAM (DRAM), or Synchronous DRAM (SDRAM)), and / or a combination of memory technologies.

[0090] The various elements of the computer system are coupled to a bus system 812. The depicted bus system 812 is an abstraction that represents any one or more separate physical buses, 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 interfaces 899 (also referred to herein as communications interfaces), one or more input / output (IO) interfaces 880, and one or more storage devices 810.

[0094] As shown in Figure 7, the computer system 800 of Figure 8 may form a component of a central computer system 700 that communicates with one or more of the device computer systems 90 of one or more individual drug administration devices 500 or housings 630, as described above. Data such as operational data of the device 500 or housing 630, patient medical data acquired by such device 500 or housing 630, may be exchanged between the central and device computer systems 700, 90.

[0095] As mentioned above, the above-described computer system 800 may also form a component of a device computer system 90 integrated into or proximate to the drug administration device 500 or the housing 630. In this regard, one or more processors 896 correspond to the processor 96, the network interface 799 corresponds to the communication interface 99, the IO interface 880 corresponds to the user interface 80, and the memory 897 corresponds to the memory 97. Additionally, an additional storage device 810 may also be present within the device computer system 90.

[0096] In an exemplary embodiment, the computer system 800 may form a device computer system 90 as a single unit, for example housed in a single package 35 of one or more drug administration devices 500 housed in a single drug administration device housing 30, or in a housing 630 with multiple drug holders 610. The computer system 800 may form a central computer system 700 as a single unit, as a single server, or as a single tower.

[0097] A single unit may be modular such that various aspects thereof may be swapped in / out as needed, for example for upgrades, replacement, maintenance, etc., without interrupting the functioning of any other aspects of the system. Thus, a single unit may also be expandable with capabilities added as additional modules and / or additional functionality of existing modules is desired and / or improved.

[0098] The computer system may also include any of a variety of other software and / or hardware components, including, by way of example, an operating system and a database management system. While an exemplary computer system is illustrated and described herein, it will be understood that this is for the sake of generality and convenience. In other embodiments, the computer system may differ in architecture and operation from that shown and described herein. For example, memory 897 and storage 810 may be integrated together, or communication interface 899 may be omitted if communication with another computer system is not required.

[0099] Implementation When delivering a drug using any of the above-mentioned drug delivery devices or any other drug delivery device, various factors may affect the drug administration, absorption, and effect on the patient beyond just the initial drug dose itself. For example, the individual patient's physiology or condition, the physiological effect of drug administration on the patient, the external conditions surrounding the patient, etc., may all affect the outcome of drug administration to the patient. Thus, being able to tailor drug delivery based on a variety of different factors that arise during the use of the drug administration device may be beneficial to the patient, providing a more personalized treatment while also helping the patient receive and / or the physician deliver specialized care for the particular patient being treated. Furthermore, being able to automate much of the drug delivery tailoring may help to ease the process of delivery for both the patient and the physician while improving patient outcomes.

[0100] As mentioned above, any of a variety of drugs can be delivered using the drug administration device. Examples of drugs that can be delivered using the drug administration device described herein include Remicade® (infliximab), Stelara® (ustekinumab), Simponi® (golimumab), Simponi Aria® (golimumab), Darzalex® (daratumumab), Tremfya® (guselkumab), Eprex® (epoetin alfa), Risperdal Constra® (risperidone), Invega Sustenna® (paliperidone palmitate), Spravato® (esketamine), ketamine, and Invega Trinza® (paliperidone palmitate).

[0101] In at least some implementations, drug delivery can be altered based on one or more characteristics associated with the patient determined based on the patient's situational awareness. In an exemplary embodiment, the drug administration device includes at least a first sensor and a second sensor each configured to collect data related to different characteristics associated with the patient. An algorithm stored in the device, e.g., in its memory, is on-board the device and executable, e.g., by its processor, to administer a dose of the drug to the patient. The algorithm is stored in the form of one or more sets of a plurality of data points that define and / or represent instructions, notifications, signals, etc., to control the function of the device and the administration of the drug. The data collected by the first sensor and the second sensor is used, e.g., by the processor, to modify at least one variable parameter of the algorithm. The at least one variable parameter is between the data points of the algorithm and is, e.g., included in the instructions for drug delivery, and thus each can be modified by modifying one or more of the stored data points of the algorithm. After the at least one variable parameter is modified, a subsequent execution of the algorithm administers another dose of the drug according to the modified algorithm. Thus, drug delivery over time can be managed for a patient to increase the beneficial results of the drug by taking into account the patient's actual situation and the patient's actual results of receiving a dose of the drug. The modification of at least one variable parameter and / or the administration of one or more doses themselves is automated to improve patient outcomes. Thus, the drug administration device can be configured to provide personalized medicine based on the patient and the patient's surrounding conditions to provide a smart system for drug delivery.

[0102] Using the universal drug administration device 500 of FIG. 5B as an example, the memory 97 can have an algorithm stored therein and the processor 96 can be configured to execute the algorithm to control delivery of the dose of drug dispensed by the dispensing mechanism 20. The processor 96 can also be configured to use data collected by at least two of the one or more device sensors 92, the environmental sensor 94, and the position sensor 98 to modify at least one variable parameter of the algorithm such that execution of the modified algorithm controls the delivered dose following a change in the at least one variable parameter. As mentioned above, one skilled in the art will appreciate that the universal drug administration device 500 can be provided with any of the various above-mentioned features in several different combinations, such as, for example, not including any of the sensors 92, 94, 98 that are not used by the processor 96 to modify the variable parameter(s) of the algorithm (instead including a sensor(s) for collecting the necessary situational awareness data), not including the package 35, not including the user interface 80, etc.

[0103] 9 illustrates an embodiment of a universal drug administration device 1000 configured to vary drug delivery to a patient based on one or more different characteristics associated with the patient determined based on patient situation awareness.

[0105] 9, device 1000 may include only two sensors or may include four or more sensors. Any additional sensors may be configured similarly to sensors 1030, 1040, 1045, or may be configured to monitor different characteristics than sensors 1030, 1040, 1045 and each other.

[0106] The memory 1050 of the device 1000 is located in the housing 1002. In this illustrated embodiment, the memory 1050 is configured to store data from the sensors 1030, 1040, 1045, although in other embodiments, this data may be stored elsewhere, such as on-board the device 1000 in a separate memory and / or in a remote memory accessible to the device 1000 via the communication interface 1099. The algorithm 1052 stored in the memory 1050 represents instructions to the device 1000 on how to administer a drug in the drug holder 1010 and is configured to be executed by the processor 1060. The algorithm 1052 is stored in the form of a plurality of data points that define and / or represent instructions, notifications, signals, etc. for controlling drug administration, with at least one variable parameter being among the data points such that changing the at least one variable parameter of the algorithm 1052 results in at least one change in how the drug is administered. The at least one variable parameter may be any of a variety of different delivery and / or drug parameters. Examples of variable parameters include the rate of delivery of drug from the drug holder 1010 to the patient, the time interval between dose deliveries such that a dose delivered after at least one variable parameter is changed has a different time interval than a dose delivered before the change, the dosage amount, the dosage concentration, whether any additional doses are delivered, e.g., whether to stop or resume administration of a second or any subsequent dose before the first dose or before any subsequent dose after the first dose after administration has previously been stopped, etc.

[0107] The processor 1060 is configured to receive and analyze data from the one or more sensors 1030, 1040, 1045 and execute an algorithm 1052 to control administration of one or more doses of the drug to the patient. In an exemplary embodiment, the processor 1060 executes the algorithm 1052 to control delivery of at least a first dose of the drug to the patient, alters at least one variable parameter of the algorithm 1052 based on data collected by the sensors 1030, 1040, 1045, and executes the algorithm 1052 to control delivery of at least one subsequent dose of the drug after altering the at least one variable parameter. In some embodiments, the processor may control the delivery of the first dose by, for example, changing at least one variable parameter of the algorithm 1052 based on data collected by the sensors 1030, 1040, 1045 prior to execution of the algorithm 1052, to change the variable parameter from indicating that administration has been stopped (e.g., the power source 1095 lacks sufficient power to deliver the dose because a device operation prevention mechanism of the drug administration device is in a state that prevents drug delivery) to indicating that administration has been permitted (e.g., the power source 1095 has sufficient power to deliver the dose because a device operation prevention mechanism of the drug administration device is in a state that allows drug delivery). To execute the algorithm 1052, the processor 1060 is configured to execute a program stored in the memory 1050 to access a plurality of data points of the algorithm 1052 in the memory 1050. To change the at least one variable parameter of the algorithm 1052, the processor 1060 is configured to modify or update the data point(s) of the at least one variable parameter in the memory 1050. The processor 1060 may also be configured to execute instructions stored in the memory 1050 to control the device 1000, which generally includes other electrical components such as the communications interface 1099, the indicators 1085, and the user interface 1080.The processor 1060 may be configured to modify at least one variable parameter of the algorithm 1052 during delivery of the dose such that the algorithm 1052 is modified in real time with delivery of the dose, which may correspond to a real time sensed condition. Alternatively, the processor 1060 may be configured to modify at least one variable parameter of the algorithm 1052 prior to the start of delivery of the dose, which may consume less memory and use less processing resources during execution of the algorithm 1052 than a real time modification of the algorithm 1052.

[0108] The processor 1060 can be configured to automatically control the delivery of doses of the drug based on one or more predefined schedules or dosing intervals for the patient, which can be pre-determined before the initial dose, or can be determined during use of the device 1000 after delivery of the first dose and can be set so that future doses can be based on the predefined schedule(s). The predefined schedule(s) can also be determined by a physician or other health care provider, can be automatically created based on the algorithm 1052 and / or the sensors 1030, 1040, 1045 used, or some combination of the two.

[0109] The processor 1060 may be configured to provide notifications to the patient and / or a physician or other healthcare provider based on collected data from one or more of the sensors 1030, 1040, 1045, for example, via the device indicators 1085, the user interface 1080, and / or the communication interface 1099.

[0110] The processor 1060 is configured to vary at least one variable parameter based on data collected by one or more of the sensors 1030, 1040, 1045, thereby allowing for an automatic reactive response based on patient situation awareness. In at least some embodiments, the at least one variable parameter is altered to provide adaptive dose adjustments based on various readings and / or data from one or more of the sensors 1030, 1040, 1045 and / or user input. For example, a user can record cycle times between disease or illness recurrences, at which point the drug administration schedule reflected in the algorithm 1052 can be adjusted by the processor 1060 and / or remotely by a physician or other medical care provider to take into account for better disease control. As another example, changes in a patient's altitude can potentially alter the effectiveness of a drug and potentially lead to toxicity. Thus, periods during which the patient is at different altitudes can be read by one or more of the sensors 1030, 1040, 1045 and used by the processor 1060 and / or a physician or other medical care provider to adjust subsequent drug dosages by the processor 1060 altering at least one variable parameter. In another example, treatment can be discontinued entirely based on one or more sensor readings, and the patient can be so notified through the device indicators 1085 and / or user interface 1080. One or more possible complications can be anticipated based on best practices, and the processor 1060 and memory 1050 can work together to provide a variety of digitally enabled responses to common complications (identified through situational awareness) to alert the patient, attempt to modify the patient's behavior, notify a physician, etc.In various embodiments, at least one of the sensors 1030, 1040, 1045 includes a camera and the processor 1060 is configured to analyze the image(s) and / or video(s) captured by the camera, for example, to analyze food intake and / or to determine the patient's skin reaction to a drug, the patient's level of sedation, the patient's level of dissociation, one or more side effects such as vomiting, etc. Facial ID can be used to identify the patient in the image(s) captured by at least one of the sensors 1030, 1040, 1045 including a camera to help ensure relevant data is collected and analyzed.

[0111] The device indicators 1085 and / or the user interface 1080 may be configured to operate independently of one another or together to provide various notifications to the patient and / or physician or other healthcare provider of any output of situational awareness based on the sensor readings and any complications those readings may indicate. Thus, the patient may be able to react quickly to any negative outcomes and / or complications of administration of the drug as a result of treatment. In at least some embodiments, the device 1000 may be configured to provide activities that the patient may pursue to best manage the patient's condition, such as by providing suggested activities via the user interface 1080. Additionally, the situational awareness information based on the sensor readings and any complications those readings may indicate may be relayed to the patient's physician or other healthcare provider, who may then communicate with the patient.

[0112] Basic operation of the device 1000 itself can, at least in some embodiments, notify the patient of any detected deviation from the so-called "five rights" of drug administration. During drug administration, best practices require ensuring that the "five rights" of drug use are followed: right patient, right drug, right time, right dose, and right route. Thus, tracking the patient's situational awareness through the use of sensors 1030, 1040, 1045 can detect if any of the "five rights" are violated, at which point the patient and / or physician or other healthcare provider can be notified. Furthermore, in some embodiments, confirmation of the "five rights" can be required by a physician or off-site healthcare provider or by the patient themselves to help eliminate medication errors and / or to ensure that the Risk Evaluation and Mitigation Strategies (REMS) of the drug are followed. In severe cases, a notification can be provided to the patient and / or physician or other healthcare provider that immediate medical attention is required.

[0113] The communication interface 1099 can be configured to allow one-way communication, such as providing data to a remote server and / or receiving instructions or commands from a remote server, or two-way communication, such as providing information, messages, data, etc. regarding the device 1000 and / or data stored in the device 1000 and receiving instructions from a physician, a remote server regarding updates to the software, etc. Thus, physician / healthcare provider interaction can provide additional coordination of care. For example, a physician or other healthcare provider can receive relevant information and data from the device 1000 and / or directly from the patient via the communication interface 1099, and based on the received information, remote feedback and / or any adjustment(s) can be provided to the device 1000 (e.g., requesting that the processor 1060 change at least one variable parameter to modify a subsequent dose) and / or to the patient (e.g., providing a recommended next step based on current sensor readings and feedback from the patient). In at least some embodiments, any records or data of the incident, as well as data leading up to and resulting from the incident, may be provided to a physician and / or remote care individual and / or a remote server for storage, and a recipient can analyze and summarize the data to determine recommendations regarding overcoming or effectively addressing any current complications. In at least some embodiments, the processor 1060 is configured to communicate with the remote server and alter the at least one variable parameter only after receiving any instructions from the remote server.

[0114] In this illustrated embodiment, the sensors 1030, 1040, 1045 are all included in the device 1000, however, one or more of the sensors 1030, 1040, 1045 may be separate from the device 1000, for example, by being worn by the patient, being located in a geographic space shared with the patient, being attached to other equipment or instruments, or being part of a mobile phone app used by the patient.

[0115] Varying the at least one variable parameter can result in an adjusted infusion or flow rate for each dose provided, for example, the at least one variable parameter can include an infusion or flow rate. Alternatively or additionally, the temperature of the drug can be varied to create a constant flow rate, as discussed in U.S. Patent Application Publication No. 2002 / 0042596, entitled "Method And Apparatus To Sense Temperature In An Implantable Pump," published April 11, 2002, and incorporated herein by reference in its entirety.

[0116] Drug delivery site pain may be minimized, in at least some embodiments, by the device 1000 monitoring patient usage, patient preferences, patient physical attributes, one or more sensed characteristics associated with the patient, various parameters of the drug, etc. For example, patient factors such as weight, BMI, age, etc., the type of delivery mechanism of the drug such as bolus injection delivery, continuous delivery, inhalation, nasal spray, etc., the total number and history of injections of the injectable drug at the desired location, the volume of the drug, the state, and the state of the drug itself such as viscosity, temperature, pH level, etc., may all be used to predict pain associated with the administration of the next drug dose, such as the next injection, the next inhalation, the next nasal spray, etc. Various delivery parameters of the drug, such as speed, waiting period, pressure, position recommendation, etc., may then be updated through at least one variable parameter to minimize pain and discomfort for the patient.

[0117] In at least some embodiments, the device 1000 can facilitate patient compliance by enabling the patient to have more situational awareness. The drug administration device 1000 can be used to improve patient compliance and / or familiarity with how the device 1000 operates in any number of different ways. For example, the device 1000 can be configured to provide reminders, updates, adaptive training to the patient based on the patient compliance data and / or patient compliance data stored or pushed to the device 1000 to reinforce healthy behaviors and instruct device usage steps and other details. Improving compliance and familiarity with device 1000 may help reduce patient risk when administering medication, the importance of which is discussed, for example, in U.S. Patent Application Publication No. 2015 / 0359966, entitled "System For Monitoring And Delivering Medication To A Patient And Method Of Using The Same To Minimize The Risks Associated With Automated Therapy," published December 17, 2015, and incorporated herein by reference in its entirety.

[0118] FIG. 10 illustrates one embodiment of the use of the drug administration device 1000. Prior to a first delivery of a dose of a drug, the drug administration device 1000 collects data on a first characteristic associated with the patient using a first sensor 1030, collects data on a second characteristic using a second sensor 1040, and collects data on a third characteristic using a third sensor 1045. The first delivery of a dose may be the initial dose delivered from the device 1000 to the patient, or may be the first dose delivered from the device 1000 to the patient after at least one dose has already been provided to the patient and after a sufficient amount of data has been collected via the sensors 1030, 1040, 1045. Further data can optionally be collected regarding additional characteristics associated with the patient by using additional secondary sensors. The collected data represents a number of data points defining each characteristic and is stored in the memory 1050. The processor 1060 then controls the delivery of a first dose of the drug from the device 1000 to the patient by executing the algorithm 1052 stored in the memory 1050. The sensors 1030, 1040, 1045 continue to collect data. Based on any of this subsequent collected data, the processor 1060 alters at least one variable parameter of the algorithm 1052. After altering the at least one variable parameter, the processor 1060 controls the delivery of at least a second dose from the device 1000 to the patient by executing the algorithm 1052. The processor 1060 executing the algorithm 1052 to deliver the dose can be automatic, manual, or some combination of the two, and can follow a predefined dosing schedule, as described above.

[0119] During any portion of the dosing process of FIG. 10, the device 1000 may communicate with one or more remote computer systems using the communication interface 1099 to provide data to and / or receive instructions from the remote computer systems, and / or communicate with a user via the device indicators 1085 and / or the user interface 1080 to provide information to and / or receive instructions from the user. In some embodiments, dosing of the first dose, the second dose, and / or any subsequent doses may be dependent on receiving instructions from one or more remote computer systems. Furthermore, the second or any subsequent doses may also be prevented entirely based on a change in a variable parameter, thus effectively resulting in the second or subsequent dose being equivalent to zero drug being administered.

[0120] For any of a variety of reasons, it may be desirable to prevent the second or any subsequent dose, or even the first dose, from being administered from the drug administration device 1000. For example, one of the sensors 1030, 1040, 1045 may be configured to monitor the patient's location, e.g., GPS or other location information. The drug administration device 1000 may be expected to be used only in certain locations, such as a hospital or medical facility, where a patient needs to receive medication from the drug administration device 1000, for example, because the drug is a controlled substance such as esketamine or ketamine that needs to be administered in a supervised facility, the patient is still learning how to properly use the drug administration device 1000, and the patient is in an observation period for use of the device 1000, etc. The drug administration device 1000 may be expected to be used only in one of multiple hospitals or other medical facilities certified to provide drugs to patients, for example, where the drug is esketamine, ketamine, or other controlled substances, in the particular city in which the patient resides, in a particular city that the patient has pre-registered to visit on a particular day / time, etc. The patient may be expected to remain at the drug administration site to help ensure that any side effects of the drug delivered from the drug administration device 1000 have dissipated before driving or otherwise leaving the drug administration site (e.g., driven by another person, walking, etc.), whereby a change in the patient's location before a predetermined threshold time has elapsed since delivery of the drug dose may render the patient ineligible from being able to receive drugs from the drug administration device 1000 in the future. If one of the sensors 1030, 1040, 1045 monitors the location of a patient who is not where drug administration is expected and / or a predetermined threshold time has elapsed since delivery of a drug dose, at least one variable parameter can be altered (or maintained) to effectively make a subsequent dose equivalent to zero drug being administered.The drug administration device 1000 may be expected to be used only in one or more specific locations (e.g., a specific GPS location, the patient's doctor's office, the patient's primary hospital, the patient's home, etc.) by a particular patient, such as when the drug is esketamine, ketamine, or other controlled substance, where the location of drug use may be important in helping to ensure that the drug is not diverted or used by unauthorized parties. For some drugs, such as esketamine, ketamine, or other controlled substances, the drug's REMS may require that the location of drug administration be recorded. The patient may be expected to remain at the drug administration location to help ensure that any side effects of the drug delivered from the drug administration device 1000 dissipate before driving or otherwise leaving the drug administration location (e.g., driven by another person, walking, etc.), whereby a change in the patient's location before a predetermined threshold time has passed since delivery of the drug dose may render the patient ineligible from being able to receive drug from the drug administration device 1000 in the future. If one of the sensors 1030, 1040, 1045 monitors the location of a patient who is not at an expected location for drug administration and / or a predetermined threshold time has elapsed since delivery of a drug dose, at least one variable parameter may be altered (or maintained) to substantially equate a subsequent dose with zero drug being administered. In some cases, the expected location for drug administration for a particular patient is the patient's home. If one of the sensors 1030, 1040, 1045 monitors the location of a patient who is not at an expected location for drug administration and / or a predetermined threshold time has elapsed since delivery of a drug dose, the patient may be disqualified from being able to administer the drug at home and may instead be required to be at a physician's office or other medical facility for drug administration, or the drug administration device may switch to a locked state in which drug delivery is prevented from the drug administration device.

[0121] In another example, one of the sensors 1030, 1040, 1045 may be configured to monitor the angular orientation of the drug administration device 1000, for example, using an accelerometer, gyro, tilt / angle switch (mercury-free), position sensor, etc. Some drug administration devices should be in a particular angular orientation relative to the patient during drug administration to help ensure that the drug is properly delivered. For example, a proper angular orientation of an injection device may be, for example, a longitudinal, substantially perpendicular orientation at substantially 90° to the patient's skin, as opposed to an improper position that is at a non-perpendicular angle to the patient's skin. Those skilled in the art will appreciate that an angle may not be exactly perpendicular (exactly 90°) but may nevertheless be considered substantially perpendicular for any of a variety of reasons, such as manufacturing tolerances and sensitivity of the measurement device. In another example, a proper angular orientation of a nasal spray device may be in the range of 30°-60°, in the range of 30°-40°, in the range of 30°-50°, in the range of 40°-50°, in the range of 50°-60°, or in the range of 40°-60°. One of the sensors 1030, 1040, 1045 configured to monitor the angular orientation of the drug administration device 1000 can be made to detect the angular orientation of the drug administration device 1000 to make it possible to determine whether the drug administration device 1000 is in a proper angular orientation for drug delivery. If one of the sensors 1030, 1040, 1045 monitors a patient position that is not in a proper angular orientation for drug delivery, at least one variable parameter can be changed (or maintained) to make the subsequent dose essentially equivalent to zero drug being administered. Once a proper angular orientation is detected, at least one variable parameter can be changed from zero to allow drug to be administered.

[0122] 37-39 show one embodiment of a drug administration device 900 that should be at a particular angular orientation relative to the patient during drug administration to help ensure proper delivery of the drug from the drug administration device 900 to the patient. The drug administration device 900 in this illustrated embodiment is an autoinjector, such as the autoinjector 100 of FIG. 1. A proper angular orientation of the autoinjector 900 for drug delivery is a perpendicular or substantially perpendicular orientation to the patient's skin, and an improper position of the autoinjector 900 for drug delivery is at a non-perpendicular angle relative to the patient's skin. FIG. 40 shows the autoinjector 900 relative to the patient's skin 904 before the autoinjector 900 contacts the patient's skin 904. Figures 39 and 41 show the autoinjector 900 in its proper angular orientation relative to the skin 904 after the autoinjector 900 has contacted the skin 904, with the autoinjector's dispensing mechanism protection mechanism, in the form of a needle shield 906 in this illustrated embodiment, pressed into the housing 908 of the autoinjector 900, and the needle 910 of the autoinjector 900, previously shielded by the needle shield 906, penetrating the skin 904 in response to the autoinjector 900 contacting and being pressed against the skin 904. Figure 39 shows the autoinjector 900 prior to drug delivery. Figure 41 shows the autoinjector 900 during drug delivery, with drug 912 ejected from the needle 910 and into the patient. 42 shows the autoinjector 900 in one of several possible improper angular orientations of the autoinjector 900 relative to the skin 904 after the autoinjector 900 has contacted the skin 904, with the needle shield 906 partially pushed into the housing 908 in response to the autoinjector 900 contacting and pressing against the skin 904. The needle shield 906 is only partially advanced into the housing 908 due to the improper angular orientation.

[0123] The autoinjector 900 includes at least one sensor 902 configured to monitor the angular orientation of the drug administration device 900. The at least one sensor 902 extends distally from a needle shield 906. The at least one sensor 902 is operably coupled to the needle shield 906 such that movement of the needle shield 906, e.g., sliding of the needle shield 906 proximally into a housing 908, also causes movement of the at least one sensor 902. The sensors 902 are positioned equidistantly around the periphery of the needle shield 906, as shown in FIG. 38, which allows data to be collected from different regions and allows a more reliable assessment to be made of the angular orientation of the autoinjector relative to the skin 904. In an exemplary embodiment, the at least one sensor 902 includes multiple sensors, as in this illustrated embodiment, which helps allow data to be collected from different regions and allows a more reliable assessment to be made of the angular orientation of the autoinjector relative to the skin 904. The at least one sensor 902 includes four sensors in this illustrated embodiment, although other numbers of sensors may be used as discussed herein. One of the sensors 902 is hidden from view in each of Figures 37, 40, and 42.

[0124] Each of the sensors 902 in this illustrated embodiment is a contact sensor configured to measure contact with a surface. If all of the sensors 902 are determined, for example, by a processor of the autoinjector 900, to be in direct contact with a surface, e.g., the surface of the skin 904, the autoinjector 900 can be deemed to be in a suitable angular orientation for drug delivery. If any one or more of the sensors 902 are not determined, for example, by a processor of the autoinjector 900, to be in direct contact with a surface, e.g., the surface of the skin 904, the autoinjector 900 can be deemed to be in an inappropriate angular orientation for drug delivery.

[0125] In another embodiment, each of the sensors 902 can be a pressure sensor configured to measure pressure. If all of the sensors 902 are determined, for example, by a processor of the autoinjector 900, to be measuring substantially the same pressure, the autoinjector 900 can be deemed to be in a suitable angular orientation for drug delivery. The sensors 902 all measuring the same pressure indicate that all of the sensors 902 are pressed equally against the skin 904 due to horizontal contact of the autoinjector 900 against the skin 904 such that the autoinjector 900 is substantially perpendicular to the skin 904. If any one or more of the sensors 902 are not measured substantially the same pressure as the other sensor(s) 902, for example, determined by a processor of the autoinjector 900, the autoinjector 900 can be deemed to be in an inappropriate angular orientation for drug delivery. The sensors 902 not all measuring the same pressure indicate that not all of the sensors 902 were pressed equally against the skin 904 due to horizontal contact of the autoinjector 900 against the skin 904 such that the autoinjector 900 was not substantially perpendicular to the skin 904.

[0126] In response to the autoinjector 900 being determined to be in a proper angular orientation based on data collected by at least one sensor 902, the autoinjector 900, e.g., a processor thereof, can be configured to move the autoinjector 900 from a locked state, in which drug delivery is prevented, to an unlocked state, in which drug delivery is permitted. In the locked state, the trigger 914 of the autoinjector cannot be pressed to inject the drug 912 into the patient. In the unlocked state, the trigger 914 can be pressed to inject the drug 912 into the patient. The autoinjector 900 can move from the locked state to the unlocked state in a variety of ways. For example, the autoinjector 900, e.g., a processor thereof, can change a variable parameter of an algorithm controlling dose delivery as discussed herein to essentially equate a subsequent dose to zero drug being administered. In another example, the autoinjector 900 can include a device motion prevention mechanism that causes the autoinjector 900, e.g., a processor thereof, to move from a locked state to an unlocked state in response to the autoinjector 900 being determined to be in a proper angular orientation based on data collected by the at least one sensor 902.

[0127] The autoinjector 900 includes a user interface 916 configured to provide information to a user of the autoinjector 900, as described herein. The light allows a user of the autoinjector 900 to easily see if the autoinjector 900 is in the correct position for drug administration. The user interface 916 in this illustrated embodiment includes a light configured to be illuminated when the autoinjector 900 is in a proper angular orientation and not illuminated when the autoinjector 900 is in an improper angular orientation. In other embodiments, the light may be configured to be illuminated a first color when the autoinjector 900 is in a proper angular orientation and illuminated a second, different color when the autoinjector 900 is in an improper angular orientation. A processor of the autoinjector is configured to control illumination of the light. The user interface 916 can have other configurations, as described herein.

[0128] The lights in this illustrated embodiment include multiple light strips of progressively shorter lengths in the proximal direction. In this illustrated embodiment, the lights include five light strips, although another number of light strips can be used. Additionally, different types of lights can be used. The autoinjector 900, e.g., its processor, is configured to sequentially illuminate the light strips in the proximal direction after the trigger 914 is depressed to visually signal to the user a countdown to drug delivery, e.g., expulsion of drug through the needle 910. FIG. 39 shows the light strips all illuminated, thus indicating drug delivery is occurring. Informing the user when drug delivery begins and when drug delivery is occurring can help provide user confidence that the autoinjector 900 is operating properly.

[0129] In yet another example regarding the prevention of administration of the second or any subsequent dose, or even the first dose, from the drug administration device 1000, one of the sensors 1030, 1040, 1045 can be configured to monitor the elapsed time, for example, using a time of day, a counter, or the like. Some drug administration devices should not deliver the second dose until a certain amount of time has elapsed since the delivery of the first dose. For example, a certain amount of time elapsed between doses delivered by a nasal spray device that delivers spray to one nostril at a time can help ensure that the nasal spray device has been moved from one nostril to another before the second dose is delivered. In another example, a certain amount of time elapsed between doses can help prevent overdosing. If one of the sensors 1030, 1040, 1045 monitors the time elapsed since the first dose that is not less than a predetermined threshold time, at least one variable parameter can be altered (or maintained) to make the subsequent dose essentially equivalent to zero drug being administered. When a predetermined threshold time has elapsed, at least one variable parameter may be altered from zero to allow administration of the drug.

[0130] 43 shows another embodiment of a drug administration device 9000 configured to visually signal a countdown to drug delivery from the drug administration device 9000 to a user. In this illustrated embodiment, a powered add-on module 9002 is configured to be attached to the drug administration device 9000 and configured to provide a countdown to drug delivery to a user interface of the add-on module 9002, e.g., using a light(s), using an audio, etc., on its display. The add-on module 9002 includes an on-board power supply configured to provide power to the user interface of the add-on module 9002. The drug administration device 9000 is an autoinjector including a needle 9004 in this illustrated embodiment, although other types of drug administration devices can be used with the add-on module 9002.

[0131] The add-on module 9002 is configured to be attached to a distal end of the drug administration device 9000, e.g., a proximal end of the drug administration device 9000 opposite the end of the drug administration device 9000 where the needle 9004 is located. The add-on module 9002 can be configured to be permanently attached to the drug administration device 9000 before a user receives the drug administration device 9000, which may help ensure that the drug administration device 9000 is used with the add-on module 9002. Alternatively, as in this illustrated embodiment, the add-on module 9002 may be configured to be removably attached to the drug administration device 9000 by a user of the drug administration device 9002 or by another entity. An add-on module 9002 that is removable may allow the add-on module 9002 to be used with each of multiple drug administration devices, thereby making the add-on module 9002 more cost-effective. The add-on module 9002 can be permanently attached to the drug administration device 9000, for example by a press fit, with a distal end of the add-on module 9002 including a cavity configured to secure a trigger button to the proximal end of the autoinjector 9000.

[0132] Whether removably or non-removably attached to the autoinjector 9000, the add-on module 9002 is configured to operably connect to a trigger of the autoinjector 9000. In an exemplary embodiment, the trigger is a trigger button at the proximal end of the autoinjector 9000. The add-on module 9002, as in this illustrated embodiment, can have a larger proximal surface area than the underlying trigger button, which makes actuation of the drug administration device 9000 easier for at least some users, e.g., users with limited dexterity and / or strength. The add-on module 9002 attached to the autoinjector 9000 is configured to be pressed to actuate the trigger, e.g., to press a button, to cause drug delivery. A user interface of the add-on module 9002 is configured to provide a countdown for drug delivery from the drug administration device 9000, similar to that described above. Initiation of the countdown is responsive to depression of the add-on module 9002 and the trigger button. The add-on module 9002 can include a switch configured to be open before the add-on module 9002 is pressed and to close in response to the add-on module 9002 being pressed. The switch closure can cause a circuit to close, thereby triggering and initiating a countdown. The add-on module 9002 can include a processor configured to control a user interface. The user interface can also be configured to indicate that drug delivery is occurring, similar to that described above with respect to the light strip, although as described above, the user interface can provide information in ways other than using a light(s).

[0133] In at least some embodiments, the processor 1060 is configured to use a hierarchy as to how data from the sensors 1030, 1040, 1045 are used in comparison to each other and / or any additional sensors. The hierarchy prioritizes one of the sensors over the other(s), whereby one serves as a primary sensor, such as sensor 1030, and the other(s) serves as a secondary or auxiliary sensor(s), such as sensors 1040, 1045. In such embodiments, the characteristic measured by the primary sensor may be considered to be the primary characteristic or defining characteristic, and the characteristic measured by the secondary sensor may be the secondary characteristic or influencing characteristic of the primary characteristic. This prioritization or hierarchy of characteristics (and thus data) may be useful when the drug administration device 1000 is used for a treatment that includes one control characteristic and one or more secondary characteristics that may influence or assist in monitoring the control characteristic, for example, when measuring blood pressure when administering a blood pressure medication, or when measuring blood glucose levels when administering insulin. Although the secondary characteristics may be useful for monitoring hypertension or hypoglycemia, the characteristic of primary concern in each embodiment is the blood pressure or blood glucose level itself, as discussed in detail below. Prioritization of data and inputs from one or more secondary sensors based on hierarchical relationships may be customizable based on desired patient outcomes, various expected or anticipated side effects, medication administered, time of day, location, activity level, caloric intake, physical activity, etc. The device 1000 may have a predefined hierarchy of levels or severity of effects on dosage based on the sensed characteristics from the sensor(s). A medical professional or unlearned algorithm within the device 1000 itself may optionally adjust the priority of levels or reorder the importance of various sensed data and inputs as a result of dosage and / or administration timeline, as discussed below.Because so much data can be collected by using multiple sensors, and because data from one sensor may sometimes contradict data from another, utilizing situational awareness to personalize drug administration to each patient can benefit from prioritization and relative comparison of multiple sources of information to arrive at the most correct conclusion or recommendation to best help the patient. This hierarchy of prioritization can be customized for a particular patient based on how that patient presents at any one time or over time, thus providing an adaptive device with reorderable hierarchical relationships.

[0134] As discussed above, the hierarchical arrangement can be used in various ways, for example to validate physiological outcomes, such that data from one or more sensors are considered to adjust at least one variable parameter to proactively manage any expected adverse effects on the primary characteristic being measured. As an example, FIG. 11 shows a chart tracking the use of the drug administration device 1000 as an insulin pump, although as discussed above the drug administration device 1000 can be another type of device. At least one variable parameter of the insulin pump includes the insulin level delivered by the pump to the patient over time. The first sensor 1030 is designated as the primary sensor and is configured to measure a primary characteristic in the form of the patient's glucose value. The designated secondary sensors 1040, 1045 are each configured to track a secondary characteristic or measurement, which in this example includes the patient's activity level, blood pressure, sweating, metabolic rate, sleep quality, and tremor detection, each of which may be sensed by a different sensor, resulting in four or more sensors being used. Tracking glucose values ​​and varying delivered insulin levels as primary characteristics allows the insulin pump, e.g., its processor 1060, to determine the typical long-term average or basal insulin levels that the patient is expected to receive, which allows the insulin pump to generally modify how much insulin it wants to deliver to the patient over time. As shown, the average insulin level may remain consistent throughout the day and then decrease during the night when the patient is typically asleep. Thus, tracking the primary characteristics allows for some modifications to the delivered insulin levels; however, they are less individualized to the patient. Tracking one or more secondary characteristics allows for more personalized and specialized care, as the insulin pump can actively manage the dosing or administration of insulin.Thus, the pump can assist in continually maintaining a patient's healthy glucose levels (e.g., about 50-200 mg / dL, more preferably about 70-120 mg / dL) instead of waiting to detect various adverse outcomes of poorly controlled insulin and glucose levels, such as hypoglycemia caused by very low glucose levels (e.g., below about 50 mg / dL).

[0135] Initially, the patient receives a baseline amount of insulin from the insulin pump via execution of the algorithm 1052, and the patient's glucose value is within a healthy range as determined by the glucose (primary) sensor. However, at time t1, the insulin pump detects the onset of vigorous exercise via one or more of the secondary sensors, for example, the activity level sensor can detect vigorous activity, the blood pressure sensor can detect an increase in the patient's blood pressure, the sweat sensor can detect an increase in sweat rate, the metabolic rate sensor can increase significantly, and the tremor detection sensor can detect a possible tremor in the patient. All of these sensor readings can be analyzed together by the processor 1060 to enable the insulin pump to determine that the patient is most likely exercising based on predefined criteria that classify sensor data from the various sensors as being within range or having a value indicative of exercise. The insulin pump can then lower the dosage and / or dosage interval by modifying at least one variable to reduce the amount of insulin provided to the patient to compensate for the exercise and thus maintain healthy glucose values.

[0136] At time t2, the insulin pump determines that exercise has most likely ended according to predefined criteria, e.g., because both the activity level sensor and the tremor detection sensor have stopped detecting motion and the other sensors indicate a gradual return to normal or resting rates. Thus, the insulin pump increases the dosage and / or dosage interval, e.g., modifies the same at least one variable that was modified previously, to compensate for the end of exercise. However, the levels are not returned to pre-dosing levels due to residual effects of exercise on the patient, e.g., an increased metabolic rate that remains elevated above the long-term average for at least several hours after exercise.

[0137] At time t3, the insulin pump determines based on predefined criteria that the patient has most likely fallen asleep based on the complete lack of readings detected from the activity level sensor, so the insulin pump reduces the dosage and / or dosage interval. Due to the hierarchical nature of the sensors, readings from the sleep quality sensor may be prioritized last or not taken at all during active times when the patient is not sleeping. However, once the patient begins to sleep, the priority of the sleep quality sensor can be increased to more significantly affect the behavior of the insulin pump. Alternatively, the sleep quality sensor can be manually activated by the patient or automatically activated based on various readings from the secondary sensor only during sleep times.

[0138] At time t5, insulin delivery can be completely terminated by the insulin pump since a possible hypoglycemic event has been detected. Glucose values ​​can be significantly lower, activity levels can begin to increase, blood pressure can drop, sweating can increase dramatically, poor REM cycles of sleep can be detected by the sleep quality sensor, and possible tremors can be detected by the tremor detection sensor. These measured characteristics can be analyzed by the insulin pump, which can identify each indicator as consistent with hypoglycemia, and the pump can therefore terminate insulin delivery by modifying at least one variable parameter to reflect no dose, for example by changing the dose to zero or by changing the dose frequency to a period that can never be achieved. Because dosing is immediately terminated at the onset of a possible hypoglycemic event, rather than waiting until glucose values ​​fall below a normal or safe threshold to only react, the patient's glucose values ​​can again begin to rise rapidly, entering a healthier or normal range at time t6 and back to the ideal range at time t7. Without monitoring one or more secondary characteristics, a hypoglycemic event may not have been detected until the patient had already had severe hypoglycemic values ​​for an extended period of time, and rapid recovery may not have been possible. Thus, the insulin pump can actively analyze data coming from the primary sensor and one or more secondary sensors to look out for signs of a possible adverse outcome that may not be easily or quickly identifiable without the ability to monitor multiple data sources at once. The pump can then immediately react to the possible event and either avoid the adverse outcome altogether, or greatly reduce the adverse effects, as shown in FIG. 11.

[0139] The hierarchy among the various sensors may be predefined, may be adaptable based on user input, such as providing input via the user interface 1085, may be adaptable based on a processor, algorithms, any analytical data, etc., and / or may be adaptable through contact with a remote computer system, a physician, a remote health care provider, etc. The insulin pump may also incorporate various functional components of an infusion pump system described in U.S. Patent Application Publication No. 2009 / 0069787, entitled "Activity Sensing Techniques for an Infusion Pump System," published March 12, 2009, and incorporated herein by reference in its entirety.

[0140] Additionally, the device indicators 1085, user interface 1080, and communication interface 1099 may enable the insulin pump to alert the user immediately prior to the onset of hypoglycemia, such as by flashing, buzzing, speaking, visual warnings, etc. Thus, the device indicators 1085, user interface 1080, and communication interface 1099 may enable the insulin pump to provide instructions to the user to eat something or get a glucose tablet, and / or to send data indicative of the collected sensor data to a remote server for later detailed analysis or to prompt immediate review by a medical professional. The medical professional may then take appropriate action to help the patient, such as calling the patient, sending a message via the insulin pump, alerting emergency services, etc.

[0141] One possible hierarchy of sensors is discussed in relation to an insulin pump in Figure 11, although other hierarchies are possible. In general, the primary characteristic of a drug delivery device may be a control measurement, and the secondary characteristic(s) or measurement may be data obtained from sources surrounding the primary characteristic and / or sources that may affect and / or be affected by the primary source. For example, blood glucose level is a primary characteristic of insulin delivery as shown in Figure 11, while blood pressure is a primary characteristic of various blood pressure medications. Additionally, sources surrounding the primary source can take a variety of different forms, such as glucose values ​​(e.g., measured by application of micro-needles and / or sweat analysis), blood pressure (e.g., measured by various wearable cuffs), overhydration (e.g., measured by sweat levels), heart rate and / or activity levels (e.g., various metabolic consumption rates, sitting or sitting motion determined by altitude changes, measured by various gyroscopes), EKG cycles, heart rate variability, various acute effects or activities to trigger a measurement (e.g., sleep or sleep quality detection and / or meal detection, etc., by analyzing one or more images of the patient, receiving input from the patient, etc.), discrimination between meals and beverages, various long term effects to monitor any changes that may inform a new diagnosis or provide an alert to assess any possible new situation, core body temperature, tremor detection, patient held / worn camera image analysis, time of day, digital calendar information, GPS output, device activity, any user interaction with the device, etc.

[0142] Additionally, many means for recognizing any surrounding situation during administration of a drug are possible beyond those discussed in connection with FIG. 11, providing various types of situational awareness that one or more drug administration devices can use. As a further example, a form of cognitive analysis can be performed on the patient by combining a small amount of interaction with the patient and various automated sensors on or around the patient to determine the cognitive effect of any drug administration on the patient. Various measured responses to the drug administration can also be analyzed such as timing of first effect, duration of effect, magnitude of effect, etc. While the insulin pump of FIG. 11 provides an example of terminating the continuous application of a drug, there are many other examples in which such an action can be performed. For example, if a biologic or drug is being delivered continuously, multiple sensors can allow for the detection of indicative complex biological responses to the biologic or drug, and the drug administration device can have the ability to affect, delay, or terminate the continuous application of the biologic or drug. Thus, the devices described herein can be configured to provide detection and automatic response of concomitant physiological responses to the introduction of any continuous biologic.

[0143] For example, injection reactions can be problematic for some biologics, especially when delivered through an IV given delivery times and continuous administration. Thus, the drug administration devices described herein can be configured to detect various signs of injection reactions, such as via a sensor(s), and thereby stop or slow the delivery of the drug. In at least some embodiments, the drug administration devices described herein can be configured to deliver other agent(s) to stop, reduce, or eliminate drug injection reactions.

[0144] As another example, cytokine release syndrome is a form of systemic inflammatory response syndrome that can result from adverse effects of some monoclonal antibody drugs, as well as adoptive T cell therapy. When the drug administration device or other system in communication with the device detects pro-inflammatory and anti-inflammatory components exceeding a predetermined threshold in the patient, the drug administration device can be configured to reduce or stop the introduction of the treatment. In such an example, the device can also be configured to notify medical personnel or introduce a cancellation agent to accelerate the reduction of the response. If the injection response is large enough as defined by predefined criteria, the drug administration device can be configured to automatically escalate the response from a passive indicator or reduction in dosage to a more active alert notification or introduction of other active measures. Even in cases where medical intervention is required, such as when a patient requires going to a hospital for emergency treatment, the drug administration device 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 lead to serious effects. The drug administration device can be configured to notify the patient of the impending effects and then allow the patient to take preemptive action, such as taking the medication at home, before one or more major side effects occur before going to the hospital. This early warning can improve patient outcomes by reducing any adverse outcomes.

[0145] As yet another example, some medications may cause drowsiness, dizziness, and / or other side effects that may adversely affect a patient's ability to drive and / or navigate safely from a hospital or other medication administration location. When such medications are administered to a patient at a location such as a hospital or other medical facility from which the patient plans to drive home (or other location), ensuring that the patient is not experiencing any of the medication's possible side effects that may adversely affect the patient's ability to drive may help prevent the patient from driving unsafely after medication administration. When the medication administration device or other systems communicating with the device detect any of the medication's possible side effects that may adversely affect the patient's ability to drive or navigate safely from the medication administration location, the medication administration device, or other systems communicating with the device, it may be configured to notify a medical practitioner. The medical practitioner may then help ensure that the patient does not leave the medication administration location until the side effect(s) have resolved and / or may enable the medical practitioner to contact the patient's preferred transportation provider from the medication administration location, e.g., a family member, a medical care provider, a taxi service, a ride-sharing service, etc., at the appropriate time. The sensor data may also help assess the side effects of drugs across patient populations. In some embodiments, a patient may not plan to drive after drug administration, but may nevertheless be determined not to be experiencing any of the drug's possible side effects that may adversely affect the patient's ability to drive or navigate safely, which may help medical personnel assess whether the patient is ready to be released. For some drugs, such as esketamine, ketamine, and other controlled substances, the patient must wait at the drug administration site for a minimum amount of time after drug administration for observation. The sensor may help ensure that at least at the end of the minimum amount of time the patient is not experiencing any of the drug's possible side effects that may adversely affect the patient's ability to drive, thereby allowing medical personnel to assess whether the patient is ready to be released from observation.

[0146] In at least some implementations, drug delivery from the drug administration device is altered based on an interaction between the drug administration device and the accessory, which represents a cooperative or closed-loop relationship between the drug administration device and the accessory. The accessory may be held within or on the drug administration device, or may be separate from the drug administration device. The accessory includes a processor configured to receive data indicative of a physiological characteristic of the patient from at least one sensor of the drug administration device, and to control delivery of the drug from the drug administration device to the patient based on the received data. Thus, the dosage may vary over time based on the sensor data and interaction with the accessory to allow for more individualized drug administration during each administration and over time, thus increasing the beneficial outcome of the drug by taking into account the actual current condition of the patient. This functionality is similar to that described above with respect to Figures 9 and 10, except that the accessory, which is not a drug administration device, manages the algorithm that controls the drug delivery from the drug administration device. Thus, this drug administration device may not be as "smart" as the drug administration device 1000 of Figure 9, and may be smaller and / or less expensive as a result. Additionally, it is typically cheaper and / or easier for a patient to upgrade an accessory and / or obtain a new accessory than it is for a patient to upgrade a drug administration device or obtain a new drug administration device, so offloading processing and algorithmic control to the accessory may extend the useful life of the drug administration device.

[0147] 12 illustrates one embodiment of a drug administration system 2000 including a universal drug administration device 2002 and an accessory 3002. The drug administration device 2002 in this illustrated embodiment includes a housing 2004, a drug holder 2010, a dispensing mechanism 2020, at least one sensor 2030, 2040, a memory 2050, a processor 2060, a user interface 2080, an indicator 2085, a power source 2095, and a communication interface 2099. The accessory 3002 in this illustrated embodiment includes a housing 3004, at least one sensor 3030, a memory 3050 configured to store an algorithm 3052 therein, a user interface 3080, a device indicator 3085, a processor 3060, a power source 3095, and a communication interface 3099. Further, similar to the above, one skilled in the art will appreciate that the universal drug administration device 2002 and the accessory 3002 can each be provided with the various features described above in a number of different combinations.

[0148] The first and second sensors 2030, 2040 of the drug administration device 2002 are similar to the sensors 1030, 1040, 1045 of FIG. 9 described above. In an exemplary embodiment, each sensor 1030, 1040 is configured to collect data regarding a physiological characteristic of the patient. For example, the sensed physiological characteristic may be any two or more of the patient's response to a drug delivered to the patient, blood glucose level, blood pressure, sweat level, heart rate, respiration rate, air sensing, angular velocity, body orientation, MARG (magnetic, angular velocity, and gravity), internal device sensing, blood oxygen level, sunlight exposure, osmolality, piezoelectric skin measurements such as changes in ultrasonic response, electrical parameters of the dermis such as impedance, biosensing, enzyme sensing, antibody sensing, histamine sensing, nucleic acid sensing, any of the characteristics discussed for the device 1000, air quality tracking, etc. Alternatively or additionally, one or both of the sensors 1030, 1040 can be configured to collect data regarding the current of the motor used to deliver the drug. U.S. Patent Publication No. 2002 / 0014951, entitled "Remote Control For A Hospital Bed," published on February 7, 2002, and U.S. Patent Publication No. 2007 / 0251835, entitled "Subnetwork Synchronization And Variable Transmit Synchronization Techniques For A Wireless Medical Device Network," published on November 1, 2007, the disclosures of which are incorporated herein by reference, further discuss various sensors. The sensors 2030, 2040 can monitor the same physiological parameter or different physiological parameters. Monitoring the same parameter allows for confirmation of a condition, while monitoring different parameters may allow for more characteristics associated with the patient to be considered for drug delivery. Although two sensors are shown in FIG. 12, device 2002 may include only one sensor, such as sensor 2030, or may include three or more sensors.Any additional sensors may operate similarly to the sensors 2030, 2040 and may also monitor various physiological characteristics. One or both of the sensors 2030, 2040 may be a biosensor, e.g., a device including a biological component and a transducer, configured to sense a biological element, such as an enzyme, an antibody, histamine, a nucleic acid, etc. The sensors 2030, 2040 may operate together as a sensor array or a dual sensor. The sensors 2030, 2040 are configured to sense their respective physiological characteristic(s), and the memory 2060 is configured to store the data internally as a plurality of data points defining and / or representing the sensed characteristic(s). The communication interface 2099 is configured to communicate data indicative of the sensed information to the accessory 3002, e.g., to its communication interface 3099, to enable the received information to be stored in the memory 3050 and analyzed by the processor 3060 to control drug delivery from the device 2002 using the algorithm 3052.

[0149] At least one sensor 3030 of the accessory is configured to sense one or more characteristics associated with the patient. The one or more characteristics may be physiological and / or situational characteristics of the patient. A variety of different physiological characteristics may be monitored, such as heart rate, respiration rate, blood pressure, sweat levels, etc. Several different situational characteristics may be monitored, such as core body temperature, time, date, patient activity level, altitude, GPS information, blood oxygen level, sun exposure, osmolality, air quality, inflammatory response, one or more images and / or videos of the patient and / or the environment in which the patient is located (e.g., for analyzing food intake, determining whether solid food or liquid is being consumed, determining the patient's location or activity, determining the patient's condition, such as skin response, respiration, eye dilation, sedation, dissociation, voice characteristics such as tone and pitch), user input data such as general health status or cycle time between recurrences of a particular disease, etc. At least one sensor 3030 is configured to sense the characteristic(s), and the memory 3050 stores the collected data as a plurality of data points that define and / or represent the sensed characteristic(s).

[0150] In at least some embodiments, one of the sensors 2030, 2040 of the drug administration device 2002 can essentially function as a primary sensor for the administration system 2000 that defines an operating range for closed-loop control of drug dosage and timing administration, and at least one sensor 3030 of the accessory 3002 can function as a secondary sensor used to provide feedback to the patient and adjust dosage, administration timing, administration location, etc. within the range defined by the primary sensor 2030.

[0151] The processor 3060 of the accessory 3002 is configured to control delivery of the drug from the device 2002 to the patient based on the sensed data received from the device 2002, and in at least some embodiments, additionally or alternatively based on data collected by the at least one sensor 3030 of the accessory. Similar to that described above, the processor 3060 is configured to control the drug delivery by modifying at least one variable parameter of the algorithm 3052, for example, adjusting at least one variable parameter of the drug dosage, i.e., the timing between drug administrations, the location of drug delivery, the concentration of the administrations, activating a set or consecutive number of individual administrations, activating continuous dosing, activating an initial bolus administration and then subsequent sporadic or repeated lesser administrations as needed, terminating the administration, skipping one or more administrations, etc. The data received by the accessory 3002 from the device 2002 is in the form of a plurality of data points that define the patient's sensed physiological characteristic(s) data. The processor 3060 may be configured to modify at least one variable parameter of the algorithm 3052 during delivery of the dose such that the algorithm 3052 is modified in real time with delivery of the dose, which may correspond to a real time sensed condition. Alternatively, the processor 3060 may be configured to modify at least one variable parameter of the algorithm 3052 prior to the start of delivery of the dose, which may consume less memory and use less processing resources during execution of the algorithm 3052 than a real time modification of the algorithm 3052.

[0152] The processor 3060 is configured to use the communication interface 2099, 3099 to send commands to the device 2002, and the processor 2060 of the device is configured to control drug delivery from the device 2002 through any of a variety of different mechanisms, such as by executing the commands that cause drug delivery (e.g., by providing a plurality of data points that define one or more instructions to the device 2002). Instead of the algorithm 3052 being stored in the accessory 3002, an algorithm for controlling drug delivery from the device 2002 can be stored in the device 2002, for example in its memory 2050. Similar to that described above, the accessory 3002 can be configured to cause at least one variable parameter of an algorithm stored in the device 2002 to be altered based on data collected by at least one sensor 2030, 2040 of the device and / or based on data collected by at least one sensor 3030 of the accessory. For example, a command may be sent to the device 2002 using the communications interface 2099, 3099, and the device's processor 3060 may execute the command to change at least one variable parameter as instructed. An algorithm stored in the device 2002 instead of the accessory 3002 may help ensure that drug delivery occurs because delivery is controlled locally, and may occur even if communication is lost between the device 2002 and the accessory 3002, for example, because the device 2002 and the accessory 3002 are out of wireless communication range of each other, because of a network system problem, because of a power loss at the accessory 3002, etc.

[0153] Figure 13 shows one embodiment of the use of the drug administration device 2002 and the accessory 3002. The use is similar to that described above with respect to Figure 10, except that the processor 3050 of the accessory 3002 is responsible for data analysis and control of dose delivery.

[0154] Various delivery types can be used from the drug administration device 2002, such as bolus or basal delivery. For example, based on the severity of a hyperglycemic or hypoglycemic reaction, a large bolus delivery can be used to prevent the patient's body from deteriorating further. In another example, an automated system can adjust basal insulin target dose size based on long-term tracking of blood glucose, continuously adjust around a target basal level based on continuous monitoring, and then introduce bolus levels only for tight adjustments.

[0155] In at least some embodiments, the drug administration device 2002 is a smart drug administration device that performs some analysis itself, and the accessory 3002 provides additional smart features to help improve efficacy, safety, and / or accuracy of the dose. For example, the smart drug administration device can be a smart insulin pump, such as Medtronic's MiniMed 670G, that allows blood glucose detection such that the pump tracks the patient's continuous glucose values ​​while adjusting the proximity between the pump and the sensor. In another example, the smart drug administration device can be a glucagon delivery device that treats hypoglycemia severity (defined by a blood glucose below 70) by injecting glucagon to raise glucose levels to a desired basal level. In yet another example, the smart drug administration device can be an insulin delivery device that continuously adjusts the amount of insulin delivered from one minute to the next based on readings from a continuous glucose monitor.

[0156] The accessory 3002 can take a variety of different forms. The accessory 3002 can be used solely to help control drug delivery from the drug administration device 2002. Alternatively, the accessory 3002 can have an additional purpose that is different from that of drug delivery from the drug administration device 2002 and is therefore multi-functional.

[0159] As discussed above, image analysis can be used to capture data within the environment around the patient. For example, as will be appreciated by those skilled in the art, image analysis can be used for a variety of purposes, including meal detection, such as to verify that a meal is occurring; analysis of the meal itself, such as volume or carbohydrate, protein, and fat content; image analysis of skin tone, injection sites, and / or other anatomical structures to determine redness, irritation, and / or other reactions; calculation of the dosage of a drug to be administered based on body area (e.g., mg / m2), such that an image of the patient's body can be used to calculate the dose in addition to any patient inputs, such as weight, age, etc. 2 ), image analysis to provide relevant medication information through interconnection between images taken by the patient and any smart digital patient device, allowing the device to provide information to the user regarding medication, dosage, timing, function, etc. U.S. Patent Publication No. 2012 / 0330684, entitled "Medication Verification And Dispensing," published Dec. 27, 2012, the disclosure of which is incorporated herein by reference, further describes image capture devices. In response to detecting a meal, the accessory can be configured to adjust medication delivery from a medication administration device in communication with the accessory.

[0160] 23 shows an embodiment of an accessory 5000 in the form of smart glasses with a built-in camera 5002. The patient 4000 can wear the accessory 5000 like regular glasses, but the accessory 5000, e.g., its processor, is configured to analyze images captured by the camera 5002 to visually identify various types of information about the meal 5004 and / or beverage 5006 being consumed by the patient 4000, such as food type, amount of food, amount of food remaining on the plate, etc. U.S. Patent Application Publication No. 2011 / 0295337, entitled "Systems and Methods For Regulating Metabolic Hormone Producing Tissue," filed December 1, 2011, U.S. Patent No. 8,696,616, entitled "Obesity Therapy And Heart Rate Variability," issued April 15, 2014, U.S. Patent No. 9,427,580, entitled "Devices And Methods For The Treatment Of Metabolic Disorders," issued August 30, 2016, and U.S. Patent No. 9,168,000, entitled "Meal Detection Devices And Methods," issued October 27, 2015, the disclosures of which are incorporated herein by reference, further describe identifying types of information about meals and / or beverages. Reliably detecting the occurrence of eating and drinking is important for safety, effectiveness, and cost, and can be combined with information sensed through situational awareness, as described above with respect to device 1000, to increase the accuracy of the eating detection methods described herein.

[0161] Accessories configured for meal detection, such as accessory 5000, can be used in a variety of different situations. For example, activation of brown adipose tissue (BAT) is known to increase metabolic activity. BAT activity results in heat production, which can be measured with several types of temperature probes. Activated BAT can have a large metabolic impact when associated with a meal. Thus, an accessory configured for meal detection can be used to detect a meal, and a detected meal can trigger the release of a drug dose used for BAT activation. Confirmation of activation can then be determined with a temperature probe mounted adjacent to the BAT depot. For example, U.S. Patent No. 9,610,429, entitled "Methods And Devices For Activating Brown Adipose Tissue With Targeted Substance Delivery," issued on April 4, 2017, and U.S. Patent No. 9,381,219, entitled "Brown Adipocyte Modification," issued on July 5, 2016, are incorporated herein by reference in their entireties and further describe drug-based activation means. U.S. Patent No. 8,812,100, entitled "Device And Method For Self-Positioning Of A Stimulation Device To Activate Brown Adipose Tissue Depot In A Supraclavicular Fossa Region," issued August 19, 2014, and incorporated herein by reference in its entirety, further describes temperature probes.

[0162] As described above, different sensor configurations and interactions can be used to generate primary and secondary measurements of the patient's physiological characteristic(s) in both the drug administration device and / or accessories. For example, the sensors used can be modular sensor arrays, configurable sensor arrays, dual sensors providing interactive sensing, dual coordinated remote sensing arrays, etc. In such examples, one or more sensors configured to detect the physiological response to drug administration in the patient can be positioned remotely relative to the injection site to prevent the drug administration itself from interfering with the results. In addition, a second sensor array can be positioned near the injection site and / or the drug administration device to determine acute local reactions and to verify that the drug administration device is operating correctly.

[0163] 24 and 26 show an embodiment of the accessory 5010 including a camera configured to collect images of the patient's 4000 eyes and / or images of the patient's skin at various points on the patient's 4000 body. The accessory 5010 is configured to monitor the patient's eye and / or skin tone at a single point or over time as shown in FIG. 25 (for analysis of data collected as shown in FIG. 24) and FIG. 27 (for analysis of data collected as shown in FIG. 26) to track any possible reactions to the drug (e.g., sleep, drowsiness, etc.) and / or to observe any inflammation (caused by administration of the drug or caused by a secondary source that the drug is administered to treat), and adjust drug delivery from a drug administration device in communication with the accessory 5010 in response to detecting the drug reaction and / or inflammation. FIGS. 25 and 27 show times t1, t2, t3, t4, t5, and t6 and corresponding photographic color charts (shown in grayscale in FIGS. 25 and 27) of the patient's skin tone at each time point. The dashed lines traced on the graphs of Fig. 25 and Fig. 27 represent slight and severe inflammation, which allows image analysis (electronically by the system or manually by a medical professional) to track inflammation and allow alerts, notifications, preemptive actions, responsive actions, etc. in response to skin tones passing slight and / or severe inflammation. Fig. 24 shows taking an image at a random point 5012 on the patient 4000. Fig. 26 shows taking an image of the patient's face 5014 and at the point of administering the drug in the form of an IV port 5016. Since the administration site (IV port 5016) is the first point of contact between the drug and the patient 4000, and the human face may represent possible adverse reactions such as allergic reactions, the administration point and face 5014 of the patient 4000 may be a useful area to monitor for any adverse or beneficial reactions to the administered drug.

[0164] 24 and 26 show the camera as part of a smartphone, the accessory configured to collect images may be a device other than a smartphone, such as a mobile tablet, a smart watch, etc. Additionally, while the same accessory 5010 is shown collecting images in FIGS. 24 and 26, two different accessories may collect the data in FIGS. 24 and 26.

[0165] FIG. 28 illustrates an embodiment of the accessory 5020 including a camera configured to collect images of the patient's 4000 body, for example in a mirror 5022. The accessory 5020 is a smartphone in this illustrated embodiment, but may be another type of accessory configured to collect images, as described above. The accessory 5020 is configured to estimate the patient's 4000 weight based on one or more of the collected images and use the estimated weight in modifying an algorithm for drug delivery from a drug administration device associated with the patient 4000. Dosages of various medications may be weight dependent, and one or more images of the patient's 4000 entire body provide the accessory 5020 and the corresponding drug administration device with a simple way to provide the correct dosage based on the patient's 4000 estimated weight. FIG. 29 illustrates an embodiment of a graph correlating estimated weight and dosage that the accessory 5020 is configured to use in adjusting dose delivery based on the estimated weight.

[0166] In at least some implementations, drug delivery from the drug administration device is altered based on awareness of the patient's condition, such as altering drug delivery based on at least one physiological characteristic of the patient and at least one associated physical characteristic of the patient. These implementations are similar to those described above with respect to drug delivery being altered based on one or more characteristics associated with the patient determined based on awareness of the patient's situation, except that the characteristics associated with the patient are determined based on at least one physiological characteristic of the patient and at least one associated physical characteristic of the patient. Implementations that take into account the physiological characteristic(s) and physical characteristic(s) allow for personalized care, adaptive drug administration processes to improve patient care, and / or automatic dose adjustments to improve the success of drug use by the patient, by varying the dosage based on the patient's condition as represented by the patient's physiological and physical characteristics. A variety of different physiological characteristics of the patient can be monitored, such as body temperature, heart rate, blood glucose level, blood pressure, sweat level, etc. A variety of different physical characteristics of the patient can be monitored, such as food intake and BMR (basal metabolic rate), weight, body temperature as measured using at least one of images and / or videos of the patient and / or the environment in which the patient is located (e.g., to analyze food intake, determine if solid food or liquids are being consumed, determine the patient's position or activity, determine the patient's condition such as skin response), metabolic needs, cognitive function, metabolic needs, etc. A variety of different physical characteristics of the patient's environment can be monitored, such as, for example, air pollutant percentage, environmental temperature, etc.

[0167] Using the universal drug administration device 500 of FIG. 5B as an example, the memory 97 may have an executable algorithm stored therein for administering a dose of drug to the patient, and the processor 96 may be configured to execute the algorithm to control delivery of the dose of drug dispensed by the dispensing mechanism 20. The processor 96 may also be configured to use physiological data representative of at least one physiological characteristic of the patient and physical data representative of at least one physical characteristic of the patient to modify at least one variable parameter of the algorithm such that the dose delivered following a change in the at least one variable parameter is controlled by execution of the modified algorithm. As mentioned above, one skilled in the art will appreciate that the universal drug administration device 500 may be provided with any of the various above-mentioned features in several different combinations, such as, for example, not including any of the sensors 92, 94, 98 that are not used by the processor 96 to modify the variable parameter(s) of the algorithm (but instead including a sensor(s) for collecting the necessary physical and physiological characteristic data), not including the package 35, not including the user interface 80, etc. The processor 96 can be configured to modify at least one variable parameter of the algorithm during delivery of the dose such that the algorithm is modified in real time with delivery of the dose, which may correspond to a real time sensed condition, or the processor 96 can be configured to modify at least one variable parameter of the algorithm prior to the start of delivery of the dose, which may consume less memory and use less processing resources during algorithm execution than a real time modification of the algorithm.

[0168] Using the universal drug administration device 1000 of Figure 9 as another example, use is similar to that described above with respect to Figures 9 and 10. The memory 1050 has an algorithm 1052 stored therein, and the processor 1060 is configured to execute the algorithm 1052 to control the delivery of a dose of drug dispensed by the dispensing mechanism 1020. The processor 1060 is also configured to use the physical and physiological characteristic data collected by at least two of the sensors 1030, 1040, 1045 to modify at least one variable parameter of the algorithm 1052 such that the dose delivered following a change in the at least one variable parameter is controlled by the execution of the algorithm 1052 with the modified dose. As mentioned above, one skilled in the art will appreciate that the universal drug administration device 1000 can be provided with any of the various above-mentioned features in several different combinations, such as, for example, not including any of the sensors 1030, 1040, 1045 that are not used by the processor 1060 to modify the variable parameter(s) of the algorithm 1052 (instead including a sensor(s) for collecting the necessary physical and physiological characteristic data), not including a user interface 1080, etc. The processor 1060 can be configured to modify at least one variable parameter of the algorithm during delivery of the dose, such that the algorithm is modified in real time with the delivery of the dose, which may correspond to a real time sensed condition. Alternatively, the processor 1060 can be configured to modify at least one variable parameter of the algorithm before the start of delivery of the dose, which may consume less memory and use less processing resources during algorithm execution than a real time modification of the algorithm.

[0169] In at least some embodiments, the at least one physiological characteristic is directly tied to the therapy administered by the drug administration device, and the device is configured to use local or real-time processing to determine and adjust the dosage to compensate for or overcome the one or more current sensed physical characteristic(s). In such embodiments, the at least one physiological characteristic is a primary characteristic that defines the response range and at least one variable parameter of the drug administration device, and the one or more physical characteristics are secondary characteristics that are used to fine-tune or influence the dosage of the device by varying the at least one variable parameter, as discussed further below.

[0170] Implementations in which drug delivery from a drug administration device is altered based on a recognition of a patient's condition may enable detection of any number of philological and / or physical characteristics. For example, detection of activity level, metabolism, and / or physical characteristics of metabolic level may affect adjustment of dosage based on increased physiological demand. In general, metabolism and metabolic rate are a blend of energy balance between caloric intake and loss and total energy expenditure. Thus, accurate measurements of activity, caloric intake, fecal caloric output, oxygen consumption / CO2 production, and the like may be used to inform metabolic activity. In such embodiments, metabolic activity may be the measured physiological characteristic, and one or more physical characteristics, such as activity, caloric intake, fecal caloric output, oxygen consumption / CO2 production, and the like, may be measured to guide adjustment of drug administration based on the measured philological characteristic. In other embodiments, a combination of various different measurements, such as activity measurements, food intake measurements, physiological measurements such as BMR, body temperature or temperature change, environmental temperature, and / or heart rate, may be used as various approximations of the patient's real-time metabolic rate, rather than attempting a more direct measurement. Metabolic rates can be determined, for example, by Lam YY and Ravussin, E., "Analysis of energy metabolism in humans: A review of methodologies," Mol Metab. 2016 Nov;5(11):1057-1071 (2016), the entire contents of which are incorporated herein by reference.<https: / / www.ncbi.nlm.nih.gov / pmc / articles / PMC5081410 / > This is discussed further in

[0171] Drug delivery adjustments in implementations where drug delivery from a drug administration device is altered based on recognition of a patient's condition may be fully automatic, partially automatic and partially manual, or fully manual, partially automatic or fully automatic devices. Some degree of automatic dosage adjustments may be particularly beneficial in situations where it may be difficult for a patient to apply any recommended changes caused by various patient conditions, environmental factors, and / or physiological factors. For example, a patient's potential and / or capacity level may be used as one or more means to decide between various degrees of user partial control over fully automated responses and / or dosage adjustments by the drug administration device. For example, a patient may normally be able to safely interact with the device(s), but during various emergency situations, the patient's capacity may be impaired and automatic action may be required.

[0172] FIG. 30 illustrates one embodiment of a drug administration device 7000 configured to have altered drug delivery based on recognition of a patient's condition. The device 7000 is a partially automated insulin pump and includes a user interface 7080 similar to the user interface 1080 and device indicators 1085 of FIG. 9. FIG. 31 also illustrates five exemplary views of the user interface 7080 showing information associated with five different events A, B, C, D, and E, which will be further described below. As shown in FIG. 32, the device 7000 is configured to measure blood glucose as a physiological characteristic, activity level and food intake as two different physical characteristics, and vary the delivered insulin level as at least one variable parameter. FIG. 32 identifies the times of events A, B, C, D, and E of FIG. 31. The device 7000 in this illustrated embodiment is configured to provide three types of possible interactions with a patient using the device 7000: a fully automatic mode with no manual override but providing alerts / recommendations, an automatic mode that provides alerts / recommendations to the patient and accepts user input, and an automatic mode that does not provide alerts / recommendations.

[0173] The events A, B, C, D, E are determined based on one or more of the physiological characteristic and / or physical characteristic sensory data. The occurrence of the events A, B, C, D, E is configured to prompt an alert / recommendation provided to the patient via the user interface 7080 and / or to prompt an automatic action by the device 7000, as shown in FIG. 31. For example, at time t a At event A at time t (see FIG. 32), an increase in activity level, such as due to exercise, is detected which causes the patient's blood glucose level to drop from over 120 mg / dL to the normal range of 120 mg / dL to 70 mg / dL. This drop does not put the patient at a dangerously low blood glucose level, but the slope of the drop may cause the patient's blood glucose level to continue to decrease, which would put the blood glucose level at a dangerous level below 70 mg / dL. This drop triggers a minor alarm by the device 7000 and a recommendation in the user interface 7080 to choose between reducing the basal level of insulin being delivered, eating something, or ignoring the recommendation (event A in FIG. 31). The user selects a time t a ~t b As shown in FIG. 32, the food intake graph is plotted at t a The broken line in indicates the suggested eating, but the recommendation was not accepted.

[0174] Time t b At event B (see event B in FIG. 32), an increase in physical activity was again detected, causing a significant drop in the blood glucose value towards a potentially lower level of 70 mg / dL. This drop triggered a major alarm and a recommendation in the user interface 7080 to eat or ignore something (event B in FIG. 31). The patient ignored the recommendation. However, the device 7000 is partially automated and therefore the device 7000 continues to monitor the blood glucose level until time t b In another embodiment, the device may ask the patient and / or physician what action to take regarding insulin delivery.

[0175] Event C and time t c At time t (see FIG. 32), because the previous activity level had not decreased, causing the blood glucose level to move into the dangerously low range of 70 mg / dL, the device 7000 provided a major alarm and recommendation in the user interface 7080 to eat something or stop all physical activity (event C in FIG. 31). The device 7000 kept the insulin delivery automatically turned off, and the device 7000 continued to sound the alarm until food intake was detected and / or all activity was stopped. At time t c , the patient ate food, represented by the solid line on the food intake graph of FIG.

[0176] Event D and time t d At (see FIG. 32), a minor alarm sounds to alert the patient that the device 7000 has resumed insulin delivery at 50% basal level (see Event D in FIG. 31). The patient has the ability to adjust the delivery percentage as needed. Blood glucose values ​​are measured at t d falls within the normal range, and t e (see FIG. 32), thus causing the device 7000 to provide one final notification that the insulin levels will automatically return to 100% basal levels, but that the patient can make changes if desired (see event E in FIG. 31). When a patient's blood glucose levels drop dangerously low, the patient's ability to think clearly can be compromised, at which point the device 7000 can automatically take a variety of actions to provide as much assistance to the patient as possible.

[0177] Thus, the drug administration device in at least some embodiments herein may be partially automatic, allowing patient and / or physician control or override of the automatic actions in various emergency situations while providing automatic actions that cannot be overridden by the patient in various emergency situations. Notifications in at least some embodiments may have priorities or tiers to them, becoming more intense as the situation becomes more dangerous for the patient. In certain drug administration devices, medical care providers and / or emergency personnel may be automatically alerted when certain major alarms sound. Furthermore, risk-based assessment of treatment may become more aggressive over time if the drug administration device detects the patient's inability to take appropriate de-escalation actions and / or an apparent lack of ability of the patient to assist in de-escalation actions itself.

[0178] Various other patient situations may lend themselves to some degree of partial or complete automation for dosage adjustments. For example, a pediatric patient may not yet understand or be able to operate a drug administration device in a safe manner, a patient may have dementia while having a disease requiring an injectable or oral medication and may not be able to understand a drug administration device, a patient may have various psychiatric disorders or illnesses that affect their ability to use a drug administration device and / or understand escalating symptoms, a patient may struggle to administer medication and may need to rely on automated actions by the drug administration device. In at least some situations, such as with injectables, which may almost always be various forms of pumps or other drug administration devices worn by the patient, it may simply make more sense to automate the recommended treatment to allow adjustments to the drug administration device and aid in compliance. For example, various diabetic side effects may increase the difficulty or inhibit the patient's ability to administer an adjusted dosage due to age, dexterity, the onset of various complex conditions (such as hyperglycemia or hypoglycemia), etc.

[0179] Similar to the accessory 5020 described above, at least some embodiments of the drug administration device may be configured to automatically adjust the dosage over time based on the weight of a patient, such as a pediatric patient, since for pediatric patients, weight tends to fluctuate more when the patient is in the process of growing. Weight measurement may be done in a variety of ways, such as from a home scale that automatically communicates the measured weight to the drug administration device, or by analyzing an image as described above. An alert of a weight change may also be provided prior to any change to the dosage actually occurring. In some circumstances, independent verification and / or approval by the patient's medical care provider may be required before a change is initiated. For example, a parent and / or physician may report the pediatric patient's weight when available, and the patient's dosing algorithm may be automatically updated with the new weight information. Any changes may be made directly on the device and / or remotely.

[0180] In at least some embodiments in which drug delivery from a drug administration device is altered based on awareness of a patient's condition, such as altering drug delivery based on at least one physiological characteristic of the patient and at least one associated physical characteristic of the patient, the patient's situational awareness may also be taken into account when altering drug delivery, e.g., similar to that described above with respect to the drug administration device 1000 of FIG. 9. For example, further taking into account situational awareness may enable the drug administration device to refine sensed data, mitigate errors, filter out or reduce inaccurate outliers, and / or otherwise selectively influence the drug administration device to improve the device's understanding of the patient's physiological response leading up to or following dosage administration. Thus, one or more sensors may function as an adaptive sensing array based on the situational awareness of the patient and / or the drug administration device.

[0181] FIG. 33 illustrates an embodiment of an adverse reaction to a drug administration device in the form of an infusion device that delivers a dose of a drug to a patient at time t1. Along with the various physiological characteristic(s) of the patient and the patient's physical characteristic(s) that the drug administration device tracks to determine the appropriate dose of the drug, the drug administration device also monitors an allergic reaction by the patient to the drug by measuring physical and physiological characteristics that may indicate an adverse reaction, such as heart rate variability, sweating, and / or pupil dilation. At time t2, heart rate variability, sweating, and pupil dilation all clearly increase beyond the minor warning threshold as illustrated, indicating a possible adverse reaction to the drug. Thus, at time t3, the dose of the drug is reduced and a bolus of medication, e.g., Benadryl, is administered by the device at a lower dosage to resolve the patient reaction. At time t4, heart rate variability, sweating, and pupil dilation all continue to increase, with heart rate variability and sweating both crossing the major warning threshold. The drug delivery device thus delivers a second, larger bolus of medication, at which point heart rate variability, sweating, and pupil dilation all begin to decrease to more normal or baseline values, at which point the patient's response is under control and the original drug can continue to be delivered at a reduced dose.

[0182] If the patient does not respond effectively to the drug administration, the original drug dose may be terminated entirely and restated at a lower, stepped value only when the various symptoms of the adverse reaction have subsided. For example, FIG. 34 shows a graph similar to that of FIG. 33, showing measured blood pressure, temperature, and pupillary dilation. At time t1, a dose of drug begins to be administered to the patient. At time t2, temperature and pupillary dilation cross warning thresholds indicating a possible adverse reaction, and the dose is reduced. At time t3, blood pressure has dropped, but both temperature and pupillary dilation continue to increase, so a dose of medication is administered. At time t4, pupillary dilation is still rising, while temperature has crossed the major threshold and blood pressure has decreased to the extent that it has crossed the lower threshold and is now too low. Thus, the drug dose is stopped entirely. At t5, blood pressure, temperature, and pupillary dilation have begun to return to normal levels, so the drug is again administered to the patient. However, the dose is further reduced. At time t6, if there is no significant increase in adverse reaction indicators from blood pressure, temperature, and pupil dilation, the dosage is again increased slightly and maintained at a lower level for the time being.

[0183] In at least some embodiments, the patient can select or opt-in to monitoring from one or more sensors in the drug administration device. For example, FIG. 35 shows one embodiment of a user interface 8080 of a drug administration device that allows the patient to opt-in to monitoring using one or more sensors, either on the device itself or via other means such as a patient app associated with the device. When the sensors are monitoring the patient as shown in FIG. 36, the sensors can detect possible or early onset joint pain at t1 and t2, for example. For example, a minor warning can be prompted at time t1 when readings from the activity level sensor and the gate analysis sensor indicate that physical activity may be too much for this patient and that continued activity would prompt joint pain. As the patient continues the activity, time point A in FIG. 38 indicates the crossing of a major threshold for heart rate variability, time point B indicates the crossing of a major threshold for sweating, and time point C indicates the crossing of a major threshold for activity level, at which point an alert sounds to indicate the onset of possible severe joint pain when all three conditions A, B, and C are met at time t2. At this point, the device and / or patient app can prompt the patient to enter a pain score, for example, by using user interface 8080, so that the device and any treatment provider can be better informed of the results of the treatment. The situational awareness measures discussed herein can be incorporated into any of the above devices to provide improved understanding of treatment and results, as well as improved personalization of treatment.

[0184] As mentioned above, some form of food intake and / or meal detection may be important when providing recommendations and adjusting dosage to the patient. Although some exemplary meal detection approaches such as image analysis are described above, various drug administration devices may also use a combination of inputs from various physiological and / or physical sensors to confirm that a meal event has occurred and is large enough to trigger a desired response in the patient. For example, analyses such as heart rate variability (HRV), image analysis, gastric pH, LINX Reflux Management device, etc. may be used independently or in some combination to provide a more accurate detection of meal consumption. Providing various overlapping measurements may help minimize errors in meal detection.

[0185] All of the devices and systems disclosed herein may be designed to be disposed of after a single use, or they may be designed to be used multiple times. In either case, however, the device can be reconditioned for reuse after at least one use. Reconditioning can include any combination of the steps of disassembly of the device, followed by cleaning or replacement of particular parts, and subsequent reassembly. Specifically, the device can be disassembled and any number of the particular parts or portions of the device can be selectively replaced or removed in any combination. Once particular parts have been cleaned and / or replaced, the device can be reassembled for subsequent use at a reconditioning facility, or by a surgical team immediately prior to a surgical procedure. Those skilled in the art will appreciate that reconditioning of a device can utilize a variety of techniques for disassembly, cleaning / replacement, and reassembly. The use of such techniques, and the resulting reconditioned device, are all within the scope of the present application.

[0186] It may be preferred that the devices disclosed herein be sterilized prior to use. This can be done by a variety of methods known to those skilled in the art, such as beta or gamma radiation, ethylene oxide, steam, and liquid baths (e.g., cold immersion). Exemplary embodiments for sterilizing devices including internal circuitry are described in more detail in U.S. Patent Publication No. 2009 / 0202387, published Aug. 13, 2009, entitled "System And Method Of Sterilizing An Implantable Medical Device." It is preferred that the device be completely sealed when implanted. This can be done by a variety of methods known to those skilled in the art.
