Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority to U.S. Provisional Patent Application No. 63 / 317,789, filed March 8, 2022, the disclosure of which is incorporated by reference as if set forth in its entirety herein.

[0002] FIELD OF THEINVENTION The present disclosure relates generally to smart liquid drug delivery. [Background technology]

[0003] Pharmaceutical products (including large and small molecule pharmaceuticals, hereafter "drugs") are administered to patients in a variety of different ways for the treatment of specific medical indications. A pump is a type of drug delivery device that can administer liquid medication to a patient. Some pumps can include a reservoir, such as a vial or cartridge, that is wearable by the patient and contains the liquid medication therein for delivery to the patient through a needle or cannula inserted into the patient.

[0004] When administering a drug to a patient, care must be taken 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. Different patients may require different doses of drug. In addition, the dose of drug to be delivered to the patient may change over the course of the patient's treatment. Pumps are traditionally configured to deliver a preset amount of drug to the patient, and thus, different patients and changes in dose requirements for patients may not be possible with such pumps. In another example, care must be taken to deliver the drug to the patient at a safe and comfortable rate. Different drugs may be delivered more comfortably at different rates. Pumps are traditionally configured to deliver drug at a preset rate, and thus, different delivery rates may not be possible with such pumps, and thus, the patient may experience discomfort. In yet another example, different reservoirs may contain different amounts of drug when loaded into the pump, but pumps traditionally do not take into account different drug volumes in the reservoirs.

[0005] Furthermore, if different drugs are available in a given drug delivery device or system, there is an increased risk that the wrong dosing regimen will be used relative to the drug actually being delivered to the patient. Summary of the Invention [Problem to be solved by the invention]

[0006] Thus, there remains a need for improved drug administration. [Means for solving the problem]

[0007] Generally, smart liquid drug delivery devices, systems, and methods are provided.

[0008] In one aspect, a drug delivery system is provided that includes, in one embodiment, a first reservoir, a second reservoir, and a pump. The first reservoir includes a first amount of a first drug therein and includes a first data storage component that stores data indicative of the first amount. The second reservoir has the same size as the first reservoir, includes a second amount of a second drug therein and includes a second data storage component that stores data indicative of the second amount. The second amount is different from the first amount. The pump is configured to receive each of the first and second reservoirs therein. The pump includes a reader configured to read the stored data from the first and second data storage components, a pumping assembly configured to drive the first drug from the pump for delivery to the patient and drive the second drug from the pump for delivery to the patient, and a control circuit operably coupled to the reader and the pumping assembly. The control circuitry is configured to receive first data from the reader indicative of the stored data read from the first data storage component, establish a first dosing regimen for delivery of the first agent using the received first data, and cause the pumping assembly to drive the first agent from the pump based on the first dosing regimen, receive second data from the reader indicative of the stored data read from the second data storage component, establish a second dosing regimen for delivery of the second agent using the received second data, and cause the pumping assembly to drive the second agent from the pump based on the second dosing regimen.

[0009] The drug delivery system can vary in many ways.

In yet another example, the first and second reservoirs can be configured to be loaded into the pump by a user. In another example, a first amount of the first agent can be delivered to the patient in a first dosing regimen and a second amount of the second agent can be delivered to the patient in a second dosing regimen. In yet another example, a first amount of the first agent can be delivered to the patient in a first dosing regimen and a less than second amount of the second agent can be delivered to the patient in a second dosing regimen.

The reservoir is configured to contain a drug therein. The reservoir includes a data storage component configured to be pre-programmed with data indicative of a dose of the drug to be delivered to a patient using the pump before the reservoir is received within the housing of the pump.

In another example, the reservoir may be configured to be non-removably received within a housing of the pump. In yet another example, the reservoir may be configured to be removably and replaceably received within a housing of the pump. In another example, the drug delivery system also includes a second reservoir configured to house a second drug therein, the second reservoir may include a second data storage component configured to be pre-programmed with data indicative of a second dose of the second drug to be delivered to the patient using the pump before the second reservoir is received within the housing of the pump, the reader may be configured to read data indicative of the second dose from the second data storage component with the second reservoir received within the housing of the pump, the control circuitry may be configured to receive data indicative of the read data indicative of the second dose from the reader, and the control circuitry may be configured to cause the pump to deliver a dose of the second drug in the second amount of the dose to the patient.

The control circuitry is configured to receive data from the reader indicative of the stored data read from the data storage component, use the received data to establish a dosing regimen for delivery of the drug, and cause the drug to be delivered to the patient based on the dosing regimen.

[0013] The drug delivery system can vary in many ways. For example, the reservoir cannot be fully received within the pump without the first and second alignment features being aligned. In another example, the reader can include a Near Field Communication (NFC) reader and the data storage component can include an NFC tag. In yet another example, the reader can include a Radio Frequency Identification (RFID) scanner and the data storage component can include an RFID tag. In yet another example, the data storage component can include an EEPROM. In another example, the location of the data storage component can maximize the number of electromagnetic field lines generated by the reader that pass through the data storage component.

The first reservoir contains a first amount of the first drug therein and includes a first data storage component that stores data indicative of the first amount. The second reservoir has the same size as the first reservoir, contains a second amount of the second drug therein and includes a second data storage component that stores data indicative of the second amount. The second amount is different from the first amount. The control circuit receives first data from the reader indicative of the stored data read from the first data storage component and establishes a first dosing regimen using the received first data, and receives second data from the reader indicative of the stored data read from the second data storage component and establishes a second dosing regimen using the received second data.

[0015] The drug delivery method can vary in many ways. For example, the control circuitry can establish a first dosing regimen prior to any delivery of a first drug from the pump to the patient, and the control circuitry can establish a second dosing regimen prior to any delivery of a second drug from the pump to the patient. In another example, the drug delivery method can also include removing the first reservoir from the pump before the second reservoir is received within the pump. In yet another example, the reader can include a Near Field Communication (NFC) reader, the first data storage component can include a first NFC tag, and the second data storage component can include a second NFC tag. In yet another example, the reader can include a QR code scanner, the first data storage component can include a first QR code, and the second data storage component can include a second QR code. In yet another example, the first data storage component can include a first EEPROM, and the second data storage component can include a second EEPROM. In another example, the first medication can be the same as the second medication. In yet another example, the first medication can be different from the second medication. In yet another example, the first and second reservoirs can be preloaded into the pump. In yet another example, the first and second reservoirs can be loaded into the pump by a user.

[0016] In another embodiment, a method of delivering a medication includes a pump reader reading data indicative of a dosage from a data storage component of the reservoir with the reservoir received within a housing of the pump, and a pump control circuit causing the pump to deliver a dose of the medication in the dosage to a patient. The reservoir contains a medication therein. The data storage component is pre-programmed with data indicative of a dosage of the medication to be delivered to a patient using the pump before the reservoir is received within the housing of the pump. The control circuit receives data from the reader indicative of the read data indicative of the dosage.

[0017] The drug delivery device may have any number of variations. For example, the dosage may be based on at least one of a pre-specified treatment and a pre-specified prescription of the drug for the patient. In another example, the dosage may be based on a pre-identified weight of the patient. In yet another example, the dosage may be based on at least one of gender, ethnicity, and genetic makeup. In yet another example, the reader may include a Near Field Communication (NFC) reader and the data storage component may include an NFC tag. In yet another example, the reader may include a QR code scanner and the data storage component may include a QR code. In another example, the data storage component includes an EEPROM. In yet another example, the control circuitry may cause one or more additional doses of the drug to be delivered from the pump to the patient, each of the one or more additional doses of the drug may be a dose. In another example, the reservoir may be non-removably received within the housing of the pump. In yet another example, the reservoir may be removably and replaceably received within the housing of the pump. In yet another example, the reservoir may be pre-loaded within the housing. In yet another example, the reservoir may be loaded into the housing by a user.

[0018] In another example, the method of drug delivery can also include a reader of the pump reading data indicative of the second dose from a second data storage component of the second reservoir with the second reservoir received within the housing of the pump, and a control circuit of the pump causing the pump to deliver a second dose of the second drug in the second dose to the patient. The second reservoir can contain the second drug therein. The second data storage component can be pre-programmed with data indicative of the second dose of the second drug to be delivered to the patient using the pump before the second reservoir is received within the housing of the pump. The control circuit can receive data from the reader indicative of the read data indicative of the second dose.

[0019] In another embodiment, a method of drug delivery includes engaging a first alignment feature of a reservoir with a second alignment feature of a pump and then receiving the reservoir within the pump. The reservoir contains a drug therein. The reservoir includes a data storage component that stores data therein relating to the drug. The pump includes a reader and control circuitry. The reader reads the stored data from the data storage component with the reservoir received within the pump. The second alignment feature engages the first alignment feature. The engagement of the first and second alignment features ensures that the data storage component is positioned within a valid read range of the reader. The control circuitry receives data from the reader indicative of the stored data read from the data storage component, uses the received data to establish a dosing regimen for delivery of the drug, and causes the drug to be delivered to the patient based on the dosing regimen.

[0020] The drug delivery method can vary in many ways. For example, the reservoir cannot be fully received in the pump without the first and second alignment features being aligned. In another example, the reader can include a Near Field Communication (NFC) reader and the data storage component can include an NFC tag. In yet another example, the reader can include a Radio Frequency Identification (RFID) reader and the data storage component can include an RFID tag.

[0022] Yet another example is a method of delivering a medication using a medication delivery system. The method includes communicatively coupling a reader of the medication delivery system to a data storage component of a reservoir of the medication delivery system. The reader reads configuration data from the data storage component of the reservoir for configuring operating parameters of the medication delivery system.

[0024] Certain exemplary embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices, systems, and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will appreciate that the devices, systems, and methods detailed herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments, and the scope of the invention is defined solely by the claims. Features illustrated or described in connection with one exemplary embodiment may be combined with features of other embodiments. Such modifications and variations are intended to be within the scope of the present invention.

[0025] Furthermore, in this disclosure, like-named components of the embodiments generally have similar characteristics, and therefore, in a particular embodiment, each feature of each like-named component is not necessarily described in full detail. Additionally, to the extent that linear or circular dimensions are used in describing the disclosed systems, devices, and methods, such dimensions are not intended to limit the types of shapes that can be used in conjunction with such systems, devices, and methods. Those skilled in the art will recognize that the equivalent of such linear and circular dimensions can be easily determined for any geometric shape. Those skilled in the art will understand that, although the dimensions are not exact values, they are believed to be close to the values ​​due to factors such as manufacturing tolerances and sensitivity of measuring equipment. The size and shape of the systems and devices, and their components, may depend at least on the size and shape of the components with which the systems and devices are used.

[0026] Generally, smart liquid drug delivery devices, systems, and methods are provided. In an exemplary embodiment, a pump is configured to receive a reservoir therein. The reservoir, e.g., a vial, cartridge, etc., contains a drug and includes a data storage component configured to store data. The pump includes a reader configured to read data from the data storage component. The pump is configured to deliver the drug from the pump to a patient with the reservoir received therein.

[0027] The data read from the data storage component may be used by the pump in controlling drug delivery from the pump. The pump may thus be configured to deliver drug differently in different circumstances depending on the stored data associated with the particular reservoir received by the pump. Multiple pumps may thus be similarly manufactured such that each has the same stock keeping unit (SKU), even though different ones of the pumps will ultimately be used to deliver different drugs and / or to deliver the same or different drugs differently. Traditionally, pumps are manufactured with different SKUs for different pump uses, e.g., a first SKU for a pump to be used for a particular treatment, a second SKU for a pump to be used for a particular notification, etc. Manufacturing a pump with a single SKU, instead of manufacturing pumps with multiple different SKUs, may reduce costs and / or facilitate inventory management and shipping / tracking. Different reservoirs usable with such pumps may have different SKUs to facilitate programming of the pump in which the reservoir is received. Producing reservoirs with different SKUs may be less complicated and cheaper than producing pumps with different SKUs for various reasons such as pumps being a more complicated technology to manufacture than reservoirs, reservoirs being produced in larger quantities than pumps, etc.

[0028] Data read from the data storage component used in controlling drug delivery from the pump can simplify complex therapies, such as high volume and multiple therapies. The pump does not need to be manually programmed to ensure the therapy is delivered properly, which can help reduce error(s) in delivering the therapy.

[0029] In some embodiments, the pump may be configured to receive only one reservoir therein. The reservoir may not be replaceable, e.g., may not be removable from the pump, in which case the pump cannot deliver any more drug(s) once the drug in the reservoir is fully delivered (or once the patient's treatment with the drug has ended without all of the drug in the reservoir having been delivered to the patient). Alternatively, the reservoir is configured to be replaced with another reservoir so that the pump can deliver any more drug to the patient once all of the drug contained in the reservoir has been delivered from the pump to the patient (or once the patient's treatment with the drug has ended without all of the drug in the reservoir having been delivered to the patient).

[0030] In some embodiments, the pump may be configured to receive at least two reservoirs therein, such that the pump has at least two reservoirs contained therein at the same time. Each of the at least two reservoirs may include a data storage component, each readable by a reader of the pump, which may be one or more readers. In this manner, data read from a particular one of the data storage components may be used by the pump in controlling delivery of the drug from that particular reservoir. The pump may thus control drug delivery differently for different ones of the reservoirs and the drugs contained therein. As described above, each of the reservoirs may be replaceable or non-replaceable.

[0031] In some embodiments, the data storage component for each reservoir receivable within the pump can store thereon data related only to its associated reservoir. In some embodiments, the data storage component for a first reservoir received within the pump can store thereon data related to at least one additional reservoir received within the pump. Each of the reservoirs can be received within the pump sequentially, e.g., in a scenario in which the pump is configured to receive only a single reservoir therein, or can be contained within the pump simultaneously, e.g., in a scenario in which the pump is configured to simultaneously contain two or more reservoirs therein. For example, in a dual therapy scenario in which a first drug is delivered to a patient and then a second drug is delivered to the patient, the data can indicate that a second reservoir subsequently received within the pump should contain a particular drug or type of drug therein. The pump, after receiving the second reservoir therein, can use this data to verify that the second reservoir contains a particular drug or type of drug therein, for example, by comparing data read from the data storage component of the first reservoir with data read from the data storage component of the second reservoir. If the pump determines that the second reservoir does not contain the expected drug or expected drug type, the pump can be configured to enter an error state in which the pump is unable to deliver the drug contained in the reservoir because the drug is not the expected drug or expected drug type.

[0032] The drugs delivered using the pumps described herein can be any of a variety of drugs. Examples of drugs that can be delivered using the pumps described herein include antibodies (such as monoclonal antibodies), hormones, antitoxins, substances for pain control, substances for thrombosis control, substances for infection control, peptides, proteins, human insulin or human insulin analogs or derivatives, polysaccharides, DNA, RNA, enzymes, oligonucleotides, antiallergy drugs, antihistamines, anti-inflammatory drugs, corticosteroids, disease-modifying antirheumatic drugs, erythropoietin, and vaccines.

[0033] The smart drug administration described herein can be used with a variety of drug delivery pumps configured to deliver drugs to a patient. The pump can be an "on-body" pump configured to be removably attached to a patient, or the pump can be an "off-body" pump configured to deliver drugs to a patient through an infusion set extending between the pump and the patient. Various examples of drug delivery pumps are described, for example, in International Publication No. WO 2021 / 124002, entitled "Liquid Drug Pumps Including User Feedback Indicating Pump Orientation," published on June 24, 2021; International Publication No. WO 2021 / 123995, entitled "Liquid Drug Pumps With A Flexible Drug Reservoir," published on June 24, 2021; International Publication No. WO 2021 / 059202, entitled "Drug Administration Device And System For Establishing a Dosing Regimen And Compatibility Of Components," published on April 1, 2021; International Publication No. WO 2021 / 059203, entitled "Drug Administration Devices That Communicate With External Systems And / Or Other Devices," published on April 1, 2021; International Publication No. WO 2021 / 059204, entitled "Drug Administration System Configured To Determine A Drug Dosing Regimen And Compatibility Of Components," published on April 1, 2021; International Publication No. WO 2021 / 059214 entitled "Apparatus For Delivering A Therapeutic Substance" published on May 31, 2018, International Publication No. WO 2018 / 096534 entitled "Apparatus For Delivering A Therapeutic Substance" published on May 9, 2019, U.S. Patent Application Publication No. 2019 / 0134295 entitled "Local Disinfection For Prefilled Drug Delivery System" published on July 12, 2011, and U.S. Patent Application Publication No. 2019 / 0134295 entitled "Disposable Infusion Device" published on July 12, 2011.No. 7,976,505, entitled "Disposable Infusion Device Negative Pressure Filling Apparatus And Method," and U.S. Pat. No. 7,815,609, entitled "Disposable Infusion Device Positive Pressure Filling Apparatus And Method," issued Oct. 19, 2010, which are incorporated by reference in their entireties.

[0034] Although the smart drug administration described herein is described with respect to a drug delivery pump, smart drug administration can be used in other drug administration devices configured to deliver liquid drugs to a patient, such as autoinjectors and jet injectors. Various embodiments of drug administration devices configured to deliver liquid drugs are described, for example, in the aforementioned WO 2021 / 059202 entitled "Drug Administration Device And System For Establishing a Dosing Regimen And Compatibility Of Components" published on April 1, 2021, WO 2021 / 059203 entitled "Drug Administration Devices That Communicate With External Systems And / Or Other Devices" published on April 1, 2021, and WO 2021 / 059214 entitled "Drug Administration System Configured To Determine A Drug Dosing Scheme" published on April 1, 2021.

[0035] 1 illustrates one embodiment of a pump 20, such as a patch pump or other pump, configured to deliver a liquid medication (also referred to herein as a "therapeutic substance") 22 to a patient. The pump 20 includes a therapeutic substance reservoir 24 that houses the medication 22 therein. The pump 20 may be configured to be removably attached to a patient in any of a variety of ways, as will be appreciated by those skilled in the art, such as by including a backing or label configured to be detached from the body of the pump 20 to expose an adhesive that can be attached to the patient. Alternatively, the pump 20 may be configured as an "off-body" pump, as described further below.

[0036] Although the reservoir 24 in the exemplary embodiment is a vial, the reservoir 24 can have other forms, such as a cartridge, a syringe, or a bag. The reservoir 24 is configured to be received within the pump 20, e.g., within the housing of the pump 20, to allow the medication 22 held within the reservoir 24 to be administered to a patient via the pump 20. The reservoir 24 can be fully contained within the pump 20, e.g., fully contained within the housing of the pump when fully inserted into the pump 20, or can be partially contained within the pump 20, e.g., a first portion of the reservoir 24 is disposed within the housing and a second portion of the reservoir 24 is disposed outside the housing. In some embodiments, the reservoir 24 is preloaded within the pump 20 by being installed within the pump 20 at the time of manufacture. Thus, a user can receive the pump 20 with the reservoir 24 already received therein, which can facilitate the user's use of the pump 20 and / or help ensure that the correct medication 22 is delivered to the patient by the pump 20. The reservoir 24 in such embodiments may be non-removably received within the pump 20 such that the pump 20 may be a disposable pump 20 configured to deliver only the medicament 22 in the reservoir 24 (through one or more separate doses of the medicament 22). In other embodiments, the reservoir 24 is loaded into the pump 20 by the user by being placed into the pump 20 by the user. The reservoir 24 in such embodiments may be non-removably received within the pump 20 such that the pump 20 may be a single-use pump 20, or may be removably and replaceably received within the pump 20 such that the pump 20 may be a reusable, multi-use pump 20 configured to be used with each of a plurality of reservoirs received within the pump 20.

[0037] In an exemplary embodiment, the reservoir 24 is pre-filled by a medical vendor or device manufacturer before the reservoir 24 is loaded into the pump 20 and thus prior to use of the pump 20 .

[0038] The pump 20 in the illustrated embodiment is configured to receive a single reservoir 24 at a time. In other embodiments, the pump may be configured to receive multiple reservoirs at a time.

[0039] The reservoir 24 includes a data storage component 48 that is attached to the reservoir 24, such as by being glued to or embedded within the reservoir 24, or that is otherwise a part of the reservoir 24, such as by being printed on the reservoir 24. The data storage component 48 is configured to store data related to the reservoir 24 and / or related to the medication 22 contained within the reservoir 24. The data storage component 48 can have a variety of configurations. For example, the data storage component 48 can include an integrated circuit configured to communicate reservoir data from the reservoir. One example of an integrated circuit is a Near Field Communication (NFC) tag, also known as a Proximity Integrated Circuit Card (PICC). ISO 14443-A passive NFC tags, ISO 15693 passive NFC tags, ISO 18000-3 passive NFC tags, ISO 14443-A / B passive NFC tags, passive FeliCa® NFC tags, or other types of NFC tags (passive or active) can be used. In another example, the data storage component 48 may include a radio frequency identification (RFID) tag. In yet another example, the data storage component may be in the form of a barcode. One example of a barcode is a QR code. Another example of a barcode is a Universal Product Code (UPC) code.

[0040] Although the reservoir 24 includes a single data storage component 48 in this illustrated embodiment, it may include multiple data storage components. If multiple data storage components are used, each may be distinct from one another, which may be useful to provide redundancy and / or enable data retrieval even when a particular type of data communication is currently unavailable, for example, when an RFID tag is not present or has been damaged such that it is unreadable, and a QR code may still be read.

[0041] FIG. 2 shows one embodiment of a reservoir that can be used as reservoir 24 with data storage component 48 attached. The reservoir is in the form of a vial 60 with a data storage component in the form of an NFC tag 62 on a flexible substrate adhered to the exterior of the vial 60. The NFC tag 62 is located on the side of the vial 60 in this illustrated embodiment, but can be located elsewhere, such as on the top of the vial 60 or on the bottom of the vial 60. It will be understood that the data storage component can be a data storage component other than an NFC tag. The top of the vial 60 is hidden in FIG. 2 by a removable protective cap 64 configured to be removed from the vial 60 before the vial 60 is inserted into the pump 20 (or other pump or drug delivery device). The location of the NFC tag 62 (or other data storage component on the vial 60 or other reservoir) can be selected to correspond to the location of the reader 50 in the pump 20 to facilitate the reader 50 being within effective reading range of the NFC tag 62. The NFC tag 62 has a square shape in this illustrated embodiment, but may have other shapes.

[0042] 3 shows another embodiment of a reservoir that can be used as reservoir 24 with attached data storage component 48. The reservoir is in the form of a vial 70 having a data storage component in the form of an NFC tag 72 on a flexible substrate adhered to the exterior of the vial 70. The NFC tag 72 in this illustrated embodiment is located at the bottom of the vial 70 and has a circular shape. It will be understood that the data storage component can be a data storage component other than an NFC tag.

[0043] FIG. 4 illustrates another embodiment of the reservoir in which the reservoir is in the form of a container 75. The container 75 is shown as a cartridge, but may alternatively be a syringe. The container 75 has a container body 75a for containing the medicament therein. A data storage component is in the form of an NFC tag 72 disposed on a side of the container body 75a. It will be understood that the data storage component may be a data storage component other than an NFC tag. The container body 75a defines a cavity configured to hold a liquid medicament therein. The container body 75a has a first end 75b and a second end 75c. The container body 75a may have a central axis extending along an axial direction. The first end 75b may define an opening therein that is open to the cavity. The medicament container 75 may include a seal 76 disposed within the cavity that forms a seal with an inner surface of the container body 75a. The seal 76 may be received within the cavity through an opening in the first end 75b. The seal 76 is configured to translate towards the second end 75c to drive the liquid medicament from the cavity.

[0044] In some examples, such as when the drug container 75 is a cartridge, the drug container 75 can include a cap 77 on the second end 75c. The cap 77 can be made of any suitable material, such as metal. The cap 77 can be crimped to the top of the container body 75a at the second end 75c. The drug container 75 can include a septum (not shown) configured to seal the second end 75c. The septum can be supported by the cap 77 and can be configured to be pierced by a piercing needle to open a fluid path into the drug container 75.

[0045] Referring again to FIG. 1 , the pump 20 also includes a reader 50 configured to read the data storage component 48. Generally, obtaining data from the data storage component 48 requires the use of an appropriate communication interface to receive data from the data storage component 48, so the type of reader 50 depends on the form of the data storage component 48 such that the reader 50 can obtain data from the data storage component 48. For example, if the data storage component 48 includes an RFID tag, the reader 50 includes an RFID scanner. In another example, if the data storage component 48 includes a bar code, the reader 50 includes a bar code scanner. In yet another example, if the data storage component 48 includes an integrated circuit, the integrated circuit can be powered and the data can be transmitted to a receiving communication interface, such as an NFC reader configured to read the RFID tag. The reader is configured to communicatively couple to the data storage component when the reader and the data storage component are in close proximity to one another such that the reader and the data storage component communicate. In some examples, the reader is configured to communicatively couple with the data storage component when the reservoir is received within the housing of the pump, but not before, hi some such examples, the reservoir must be received within the housing of the pump in a particular orientation in order for the reader to communicatively couple with the data storage component.

[0046] In some examples, the reader 50 can receive data as well as transmit data and, optionally, write that data to the data storage component 48. In some such examples, the data storage component 48 can be updated at regular intervals (e.g., upon completion of each mL of delivery) so as to contain a reasonably accurate record of the delivery progress at any given time. If the pump 20 fails during delivery, resulting in a volume being partially delivered, the reservoir containing the record of the partial dose can be transferred to a secondary pump, where the remaining dose can be delivered. In some such examples, the data storage component 48 can also be updated with any information related to the delivery and the pump status during delivery.

[0047] For example, the information can include the date and time of delivery, pump model and serial number, ambient pump and reservoir temperatures, pump user input settings, pump wireless communication events, pump warning or alarm events, user initiated pauses and durations, user interface events, and / or relevant pump parameter settings and measurements (force, pressure, battery voltage / current, etc.) during delivery. Thus, the data storage component 48 can function as a record of the delivery (e.g., a delivery "black box" record). The data storage component 48 can be designed to be easily peeled away from the reservoir so that the data storage component 48 can be transported to a monitoring party or HCP for subsequent reading, recording, and analysis. Once the delivery is complete, the data storage component 48 can be updated with a "delivery complete" status, thus preventing the reservoir from being refilled and reused in a pump, including those with the capabilities described by this disclosure.

[0048] In an exemplary embodiment, reader 50 is a single reader, which may help reduce the cost of pump 20, help conserve space within pump 20 for other components, and / or help reduce the overall size of pump 20. Reader 50 may instead include multiplexed readers, which may allow one of the readers having the best communication with data storage component 48 to be the reader used, and / or may help provide redundancy, allowing read data to be verified against each other for accuracy.

[0049] The reader 50 is configured to read data from the data storage component 48 when the data storage component 48 is within a valid read range of the reader 50 and the reader 50 is "on". The reader 50 is "on" when the reader 50 is provided with sufficient power to read the data. In an exemplary embodiment, the pump 20, which is powered on, is configured to power on the reader 50. Thus, the reader 50 can be configured to read data from the data storage component 48 upon powering on of the pump 20, if the reservoir 24 has already been inserted into the pump 20, thereby causing the data storage component 48 to be within a valid read range of the reader 50. The reservoir 24 is typically inserted into the pump 20 with the pump 20 powered off or in a low or power save mode. Thus, powering on the pump 20 can trigger the reader 50 to automatically read data from the data storage component 48. Therefore, since the pump 20 cannot deliver medication 22 to the patient while the pump 20 is powered off or in a low power or power saving mode, the reader 50 can be configured to read data from the data storage component 48 prior to the first delivery of medication 22 from the pump 20.

[0050] The pump 20 can be powered on by a user of the pump 20, thereby allowing the data to be read from the data storage component 48 after the user receives the pump. In such an embodiment, the reservoir 24 can be user loaded or preloaded. Alternatively, in an embodiment in which the reservoir 24 is preloaded in the pump 20 during manufacture, the pump 20 can be powered on during manufacture, thereby allowing the data to be read from the data storage component 48. Thus, data can be read from the pump 20 before the user receives it. After the data is read from the data storage component 48, the pump 20 can be powered off or placed in a low power or power saving mode to await later turning on by the user.

[0051] In one embodiment, reader 50 may include a printed circuit board (PCB) having mounted thereon an NFC transceiver, such as a DLP7970A NFC transceiver available from DLP Design Inc. of McKinney, Texas, or other type of NFC transceiver, and a microcontroller, such as an MSP430G2553 microcontroller available from Texas Instruments, Inc. of Dallas, Texas, or other type of microcontroller. The DLP7970A transceiver is configured to read passive NFC tags. In such an embodiment, reader 50 is not configured to directly contact data storage component 48.

[0052] FIG. 5 shows one embodiment of a reader antenna 80 that can be used as the reader 50. The reader antenna 80 in this illustrated embodiment is an RFID / NFC R25 reader antenna configured for use with RFID and NFC tags. The reader antenna 80 in this illustrated embodiment is on a thin polyester or polyimide flex film substrate, which can facilitate reading RFID or NFC tags that are on a curved surface of a reservoir, such as on a cylindrical side of a reservoir as shown in FIGs. 2 and 4 for reservoirs 60, 70. This is because the reader antenna 80 can be attached to a curved surface within the pump 20 that corresponds to the curvature of the data storage component on the side of the reservoir 24 to facilitate positioning of the reader relative to the data storage component 48. In this illustrated embodiment, the reader 50 is not configured to directly contact the data storage component 48.

[0053] 6 and 7 show one embodiment of a flexible printed circuit board assembly (PCBA) 90 that can be used as the reader 50. The PCBA 90 is configured to read passive NFC tags. The PCBA 90 includes a one-wire electrically erasable programmable read-only memory (EEPROM) with exposed pads. A spring contacts the main PCB of the PCBA 90 to read from the one-wire EEPROM. In this illustrated embodiment, the reader 50 is configured to directly contact the data storage component 48.

[0054] 1 , the pump 20 includes a control circuit 36 ​​configured to control dispensing of medication 22 from the pump 20 based at least in part on data received from the reader 50, such as based at least in part on data stored on the data storage component 48 of the reservoir 24 and read by the reader 50. In some embodiments, the reader 50 is configured to automatically read the data from the data storage component 48 and transmit data indicative of the data read from the data storage component 48 to the control circuit 36. In other embodiments, the control circuit 36 ​​is configured to transmit instructions to the reader 50, read the data from the data storage component 48, and transmit data indicative of the data read from the data storage component 48 to the control circuit 36, for example, upon power-on of the pump 20.

[0055] The control circuitry 36 is configured to control the administration of the medication 22 from the pump 20 according to a dosing regimen. The dosing regimen refers to the particular manner in which the medication is delivered, including, but not limited to, the formulation, the route of administration, the dosing interval (dosing frequency), the dosage or volume, the delivery rate (flow rate), the duration of delivery, pauses in delivery, pauses between delivery phases in a multiple medication delivery sequence, and the sequencing sequence of a multiple medication delivery sequence. The dosing regimen may be stored in the memory of the control circuitry 36 as an algorithm that the processor of the control circuitry 36 is configured to execute. The algorithm is stored in the form of one or more sets of data points that define and / or represent instructions, notifications, signals, etc., to control the administration of the medication from the pump 20.

[0056] The algorithm includes one or more variable parameters that can be altered by the control circuitry 36 such that the dosing regimen can be changed. The variable parameters are between the data points of the algorithm and therefore each can be altered by altering one or more of the stored data points of the algorithm. The control circuitry 36, e.g., its processor, is configured to establish at least one of the one or more variable parameters based on data received from the reader 50, based at least in part on data stored on the data storage component 48 of the reservoir 24. The data received by the control circuitry 36 from the reader 50 identifies the variable parameter(s) to be established and the value of each variable parameter to enable the control circuitry 36 to update the algorithm to include the variable parameter values ​​indicated by the data. After the dosing parameters are established, subsequent execution of the algorithm by the control circuitry 36, e.g., its processor, administers a dose of the medication 22 according to the algorithm that reflects the current dosing regimen. Thus, because different data storage components store different variable parameter values ​​based on the particular drug 22, based on the particular therapy the drug 22 is being used to treat a particular disorder, and / or based on the particular patient to whom the drug 22 is intended to be delivered using the pump 20, the drug 22 can be administered to the patient on a customized basis, thereby improving patient outcomes by enabling the pump 20 to deliver the drug 22 according to the requirements of a particular treatment, a particular drug, and / or a particular patient, and / or by facilitating personalized medicine. Thus, the pump 20 can be manufactured in a generic manner and later programmed to take into account the requirements of a particular treatment, a particular drug, and / or a particular patient. Thus, the supply chain can be simplified and become more cost-effective.

[0057] The pump 20 also includes a conduit 38 configured for the medication 22 to pass from the reservoir 24 into the inlet fluid pathway 30 operatively connected to an injector assembly 46 of the pump 20, which is configured to deliver the medication 22 to the patient. The conduit 38 is thus a tube through which the medication 22 can flow. Instead of being an "on-body" pump configured to be removably attached to the patient, the pump 20 may be an "off-body" pump configured to deliver medication to the patient through an infusion set extending between the pump and the patient. An "off-body" pump is generally constructed and used similarly to the pump 20, except that the injector assembly 46 may be configured differently or may be replaced with another type of assembly for use with an infusion set.

[0058] The pump 20 also includes a user interface 40 configured to provide information to a user of the pump 20, e.g., a patient associated with the pump 20 (e.g., wearing the pump 20 by having the pump removably attached to the patient using an adhesive or other attachment mechanism, or operably connected to the pump 20 via an infusion set), a patient caregiver assisting the patient in using the pump 20, a medical professional assisting the patient in using the pump 20, etc. The user interface 40 can have a variety of configurations, and the pump 20 can include a single type of user interface or can include two or more types of user interfaces. For example, the user interface 40 can include one or more lights, e.g., light emitting diodes (LEDs) or other types of lights, configured to illuminate to provide various information. Examples of information shown by the user interface 40 include power (on / off) status, error conditions (e.g., an indication that an error has been detected in the pump 20, such as low power supply, improper needle advancement into the patient, an incompatible type of reservoir 24 loaded into the pump 20, etc.), drug delivery status (e.g., an indication that drug delivery is currently occurring), drug delivery progress information, an orientation of the pump 20 with respect to gravity, an indication of the dose of drug 22 to be provided in each delivery of the drug 22 to the patient, and other types of information. As another example, the user interface 40 can include a display configured to show information thereon, such as by using text and / or graphics. The display can include a display screen having any of a variety of configurations, such as a cathode ray tube (CRT), a liquid crystal display (LCD), a touch screen, etc. In yet another example, the user interface 40 can include a vibration mechanism configured to vibrate, the vibrations configured to be felt by a patient wearing the pump 20. In yet another example, the user interface 40 can include a speaker configured to provide an audio signal. In another example, the user interface 40 can include a machine level configured to indicate the orientation of the pump.

[0059] The control circuitry 36 is operably coupled to the user interface 40 and configured to cause the user interface 40 to provide information to a user. The control circuitry 36 is also operably coupled to the reader 50 and configured to receive data from the reader 50 indicative of the data read from the data storage component 48, e.g., receive a signal from the reader 50 indicative of the read data. The control circuitry 36 is configured to control the pump 20 using the data received from the reader 50, as described further herein.

[0060] The electromechanical pumping assembly 26, e.g., its motor, is operably connected to the reservoir 24 and is configured to cause delivery of the therapeutic substance 22 to the patient via the injector assembly 46, e.g., through a needle or cannula of the injector assembly 46 inserted into the patient. The electromechanical pumping assembly 26 is shaped to define a rigid pump chamber 28 including a therapeutic substance inlet 30 through which the therapeutic substance 22 is received from the conduit 30, and thus from the reservoir 24, into the pump chamber 28. The rigid pump chamber 28 also includes a fluid pathway outlet 32 ​​through which the therapeutic substance 22 is delivered from the pump chamber 28 to the patient via the injector assembly 46. Although the pumping assembly 26 is electromechanical in this illustrated embodiment, the pumping assembly of the pump 20 (and for other embodiments of the pumps described herein) may instead be any suitable alternative pumping assembly, such as a mechanical pumping assembly (e.g., involving a spring), a pneumatic pumping assembly, or a hydraulic pumping assembly. A mechanical pumping assembly need not include electronic components or a controller. For example, the mechanical pumping assembly can include a balloon diaphragm configured to be actuated to cause delivery of the agent by mechanical action.

[0061] The pump 20 also includes a plunger 34 that is slidably disposed within the pump chamber 28 and in sealable contact with the interior of the pump chamber 28. The plunger 34 is configured to directly contact the medication 22 within the pumping chamber 28.

[0062] The electromechanical pumping assembly 26 in the illustrated embodiment is configured to be driven to operate in two pumping stages by the control circuitry 36. In other embodiments, the control circuitry 36 may be configured to drive the electromechanical pumping assembly 26 in other manners, such as by operating in a single stage, by operating in three or more stages, or by operating in first and second pumping stages that are configured differently than the first and second pumping stages described below.

[0063] In a first pumping stage, the control circuit 36 ​​is configured to drive the plunger 34 (e.g., slidably move the plunger 34 within the pump chamber 28) to draw the medication 22 from the reservoir 24 into the conduit 38, then into the inlet fluid path 30, and then through the inlet valve 42 into the pump chamber 28. The inlet valve 42 is configured to be opened and closed such that when the inlet valve 42 is open, there is fluid communication between the reservoir 24 and the pump chamber 28, and when the inlet valve 42 is closed, there is no fluid communication between the reservoir 24 and the pump chamber 28. During the first pumping stage, the control circuit 36 ​​is configured to cause the inlet valve 42 to open and the outlet valve 44 to close, and to drive the plunger 34 to draw the therapeutic substance 22 from the reservoir 24 into the pump chamber 28, e.g., the control circuit 36 ​​is configured to set the inlet valve 42 and the outlet valve 44 such that the therapeutic substance 22 can flow only between the reservoir 24 and the pump chamber 28. This draws the therapeutic substance 22 into the pump chamber 28 as the plunger 34 is retracted. The control circuit 36 ​​that causes the inlet valve 42 to open and the outlet valve 44 to close can be an active control, or a passive control in which the valves 42, 44 are mechanical valves that open and close automatically when actuated by the plunger 34.

[0064] In the second pumping stage, the control circuit 36 ​​is configured to drive the plunger 34 to deliver the medication 22 from the pump chamber 28 through the outlet valve 44 to the outlet fluid pathway 32 and then to the injector assembly 46 for delivery to the patient. The outlet valve 44 is configured to be opened and closed such that when the outlet valve 44 is open there is fluid communication between the pump chamber 28 and the patient, and when the outlet valve 44 is closed there is no fluid communication between the pump chamber 28 and the patient. During the second pumping stage, the control circuit 36 ​​is configured to cause the inlet valve 42 to close, the outlet valve 44 to open, and drive the plunger 34 to deliver the therapeutic substance 22 from the pump chamber 28 in multiple separate movements of the plunger 34. For example, the control circuit 36 ​​can be configured to set the inlet valve 42 and the outlet valve 44 such that the therapeutic substance 22 can only flow between the pump chamber 28 and the patient, and the plunger 34 is gradually pushed back into the pump chamber 28 in multiple separate movements, thereby delivering the therapeutic substance 22 to the patient in multiple separate doses. Similar to that described above, the control circuit 36 ​​that causes the inlet valve 42 to close and the outlet valve 44 to open can be an active control, or it can be a passive control in which the valves 42, 44 are mechanical valves that open and close automatically by actuation of the plunger 34.

[0065] In some embodiments, the control circuitry 36 is configured to drive the plunger 34 to draw the therapeutic substance 22 into the pump chamber 28 with a single movement of the plunger 34, e.g., the plunger 34 is pulled back in a single movement to draw a volume of the therapeutic substance 22 into the pump chamber 28 during a first pumping stage. Alternatively, the control circuitry 36 can be configured to drive the plunger 34 to draw the therapeutic substance 22 into the pump chamber 28 with one or more discrete extensional movements of the plunger 34, e.g., the plunger 34 can be pulled halfway out of the pump chamber 28 in one movement and then the remaining portion out of the pump chamber 28 in a second separate movement. In this case, the duration of the extensional movement of some or all of the plunger 34 during the first pumping stage is typically longer than the duration of any of the multiple discrete movements of the plunger 34 during the second pumping stage.

[0066] In other embodiments, the control circuit 36 ​​is configured to drive the plunger 34 such that the duration of the first pumping stage and the duration of the second pumping stage are not equal. For example, the duration of the second pumping stage can be in the range of 5 to 50 times longer than the first pumping stage, e.g., at least 10 times, 30 times, 50 times, etc. longer than the duration of the first pumping stage.

[0067] The pump 20 may also include a power source (not shown) configured to provide power to components that require power to operate, such as the control circuit 36 ​​and the reader 50. In an exemplary embodiment, the power source is a single power source configured to provide power to each component of the pump 20 that requires power to operate, which may help reduce the cost of the pump 20, help save space within the pump 20 for other components, and / or help reduce the overall size of the pump 20. However, the power source may include multiple power sources, which may help provide redundancy and / or help reduce the cost of the pump 20, since some components may be manufactured with an on-board dedicated power source. In an exemplary embodiment, the power source is on-board the pump 20, which may facilitate use of the pump 20 at any time in any location. In other embodiments, the power source may include a mechanism configured to connect the pump 20 to an external power source.

[0068] The amount (e.g., volume) of drug 22 that the pump 20 delivers to the patient per dose may vary from disorder to disorder and / or from patient to patient. The dosage may vary for a variety of reasons. For example, different drugs may be administered in different doses, for example because some drugs may have more and / or stronger risk of side effects at higher volumes than others, some drugs are more concentrated than others, etc. Thus, depending on the particular drug 22 held by the reservoir 24, the amount of drug 22 per dose that the pump 20 should deliver to the patient may vary. In another example, different patients may receive different amounts of the same drug per a particular patient's prescription. Thus, depending on the particular patient to whom the drug 22 is delivered from the reservoir 24, the dosage may vary even if the pump 20 is the same. In yet another example, depending on the disorder indicated to treat the particular disorder, the amount of drug 22 per dose that the pump 20 should deliver to the patient may be altered. Thus, depending on the particular treatment for which the drug 22 is used, the dosage may vary, even if different dosages may be used for other treatments involving delivery of the same drug 22. A disease is one example of a pre-specified characteristic for a patient. In another example, the dosage of the drug 22 may vary for the same patient even though the pump 20 remains the same as the patient's treatment may change over time. In yet another example, the dosage may vary for the same pump 20 depending on gender as a patient population factor. In another example, the dosage may vary for the same pump 20 depending on ethnicity as a patient population factor. In yet another example, the dosage may vary for the same pump 20 depending on genetic makeup as a patient population factor. For example, a patient having a particular genetic makeup, including certain genes such as tumor suppressor genes, may affect the amount of drug a particular patient should receive. The reservoir 24 may include a sensor thereon configured to read a patient biomarker indicative of the genetic makeup. Data regarding the read biomarker may be included in the data read from the data storage component 48. In yet another example, the dosage may be based on the weight of the particular patient to whom the drug 22 is delivered from the reservoir 24.In such a weight-based dosing scheme, the amount of medication 22 delivered from the reservoir 24 to the patient per dose is calculated based on the weight of a particular patient. The patient's weight is one example of a pre-specified characteristic for the patient. Thus, even though the pump 20 is the same for a patient and the medication 22 is the same for a patient, the dosage may vary between patients because different patients have different weights.

[0069] In at least some embodiments, the reservoir 24 is intended for use with a particular patient such that the medication 22 contained within the reservoir 24 is intended to be delivered to a particular patient. The data storage component 48 is configured to store data indicative of a dosage of the medication 22 to be delivered to a particular patient from the pump 20 to which the reservoir 24 is operably coupled. The data indicative of the dosage is preprogrammed into the data storage component 48 before the reservoir 24 is received by the pump 20. The data may be preprogrammed in a variety of ways as appropriate for the particular type of data storage component 48. With the reservoir 24 operably coupled to the pump 20, a reader 50 of the pump is configured to read the preprogrammed dosage data from the data storage component 48. As discussed herein, the reader 50 is configured to read and collect data from the data storage component 48 and is configured to transmit data indicative of the read data to the control circuitry 36. Also as discussed herein, the control circuit 36, e.g., its processor, is configured to adjust an algorithm stored in the control circuit 36, e.g., its memory, to control future delivery of the medication 22 from the pump 20 based at least in part on the data.

[0070] In at least some embodiments, the pre-programmed dosage reflects a weight-based dosing scheme and is based on the weight of the particular patient using the pump 20. A weight-based dosing scheme can help ensure that the patient receives enough of the drug 22 per dose of the drug 22 to effectively provide the intended treatment without receiving too much of the drug 22, which would waste the drug 22 and / or increase the risk and / or magnitude of side effects.

[0071] In at least some embodiments, the preprogrammed dosage reflects a non-weight-based dosage prescribed for a particular patient using the pump 20. Thus, the pump 20 can deliver an appropriate amount of medication 22 to the patient to maximize the effectiveness of the treatment for a particular patient.

[0072] In at least some embodiments, the preprogrammed dosage reflects a particular therapy for treating a particular disorder, and thus the pump 20 can deliver an appropriate amount of the drug 22 to the patient to maximize the effectiveness of the treatment.

[0073] In at least some embodiments, the preprogrammed dose does not change with each dose of medication 22 that the pump 20 delivers to the patient.

[0074] In at least some embodiments, the preprogrammed dosages are different for different doses of the drug 22 that the pump 20 delivers to the patient. Over time, the patient can receive different amounts of the drug 22 from the pump 20 to maximize the patient's treatment with the drug 22. For example, some drugs are delivered in a split-dosing configuration in which an initial dose of a first amount of the drug 22 is delivered to the patient, at least one transition dose of a second amount of the drug 22 is delivered to the patient after the initial dose, and at least one maintenance dose of a third amount of the drug 22 is delivered to the patient after the transition dose(s). The first, second, and third amounts of the drug 22 are different from one another. Data stored in the data storage component 48, read by the reader 50, and communicated to the control circuit 36 ​​can reflect each of the first, second, and third amounts. Thus, a dosing regimen may be established in which doses of medication 22 vary over time, such that an initial dose (first dose), then transition dose(s) (second dose), then maintenance dose(s) (third dose) are delivered to the patient via pump 20.

[0075] In at least some embodiments, the data storage component 48 is configured to store data indicative of a delivery rate of the drug 22 to be delivered from the pump 20 to which the reservoir 24 is operably coupled. The delivery rate may vary from treatment to treatment, for example, taking into account drug viscosity. The data indicative of the delivery rate is preprogrammed into the data storage component 48 before the reservoir 24 is received by the pump 20. The data may be preprogrammed in a variety of ways as appropriate for the particular type of data storage component 48. With the reservoir 24 operably coupled to the pump 20, a reader 50 of the pump is configured to read the preprogrammed delivery rate data from the data storage component 48. As discussed herein, the reader 50 is configured to read and collect data from the data storage component 48 and is configured to transmit data indicative of the read data to the control circuitry 36. As also discussed herein, the control circuit 36, e.g., its processor, is configured to adjust an algorithm stored in the control circuit 36, e.g., its memory, to control future delivery of the medication 22 from the pump 20 based at least in part on the data, e.g., such that the medication 22 is delivered at the delivery rate read from the data storage component 48.

[0076] As mentioned above, the reservoirs 24 may be removably and interchangeably received within the pump 20 such that the pump 20 may be a reusable, multi-use pump 20 configured to be used with each of the multiple reservoirs 24 received within the pump 20. Each of the reservoirs 24 received within the pump 20 includes its own data storage component 48, which allows the pump 20 to control the delivery of the medication 22 from each of the reservoirs 24 in a customized manner, with the pump 20 updating the dosing regimen based on the stored data of the particular reservoir. Thus, a single pump 20 may be used to deliver medication according to different dosing regimens. In some embodiments, each of the multiple reservoirs 24 received within the pump 20 contains the same type of medication 22 therein such that the pump 20 may control the delivery of the same type of medication 22 to a single patient differently based on the data preprogrammed within the data storage component 48 of each reservoir. In other embodiments, one or more of the multiple reservoirs 24 received within the pump 20 contains a different type of medication 22 therein than one or more of the other multiple reservoirs 24, such that the pump 20 is capable of delivering at least two different types of medication 22 to a patient, and the delivery of each of the different types of medication 22 can be controlled based on data preprogrammed into the data storage component 48 of each reservoir.

[0077] In an embodiment where the pump 20 is a reusable, multi-use pump 20 configured to be used with each of a plurality of reservoirs 24 received within the pump 20, each of the reservoirs 24 may be the same size as one another, and each of the reservoirs 24 is configured to contain the same maximum amount of drug therein. Each of the reservoirs 24 having the same size may help ensure that the reservoir 24 is properly seated within the pump 20 so that the drug 22 contained therein can be properly fluidly communicated with the injector assembly 46 of the pump 20. The same amount of drug 22 may be contained in each of the plurality of reservoirs 24 of the same size. FIG. 1 shows a first fill level 52 of drug 22 that may be used in each of the plurality of reservoirs 24 of the same size (the reservoirs 24 are inverted in FIG. 1 so that the top ends of the reservoirs 24 face downwards). It may be efficient and cost effective for the plurality of reservoirs 24 to be manufactured identically to one another and each to be loaded with the same amount of drug 22 therein. However, not all patients need to receive all of the drug 22 contained therein, e.g., due to different prescriptions, different patient weights. Thus, excess drug 22 may be left in the reservoir 24 as not delivered to the patient. Thus, in some embodiments, different amounts of drug 22 may be contained in different reservoirs of the same size reservoirs 24, such that at least one of the reservoirs 24 contains a different amount of drug 22 than at least one other reservoir of the plurality of reservoirs 24. Thus, a reservoir 24 containing an amount of drug 22 appropriate for a particular patient, particular treatment, etc. may be inserted into the pump 20. Thus, drug may not be left in the reservoir 24 as excess to be discarded with the reservoir 24, while still allowing for efficient and cost-effective manufacture of reservoirs 24 of the same size, each configured for use with the pump 20. For example, one or more of the plurality of reservoirs 24 may have a first fill level 52, and one or more of the other reservoirs 24 may have a second, different fill level 54. One or more additional different fill levels may be used.

[0078] The fill levels can vary between reservoirs 24 of the same size by any increment, such as about 0.5 mL, about 1 mL, about 1.5 mL, about 2 mL, about 5 mL, etc. One skilled in the art will appreciate that the amount need not be exactly a value, but is considered to be approximately that value due to any number of factors, such as manufacturing tolerances and sensitivity of measurement equipment. For example, the first and second fill levels 52, 54 can differ by about 0.5 mL, about 1 mL, about 1.5 mL, about 2 mL, about 5 mL, etc.

[0079] 16, an alternative pump 20', e.g., a patch pump or other pump, is shown that is configured to deliver a liquid medication 22 to a patient. The pump 20' includes a therapeutic substance reservoir 75 that houses the medication 22 therein. The pump 20' may be configured to be removably attached to the patient in any of a variety of ways, as will be appreciated by those skilled in the art, such as by including a backing or label that is configured to be detached from the body of the pump 20 to expose an adhesive that can be attached to the patient. Alternatively, the pump 20' may be configured as an "off-body" pump.

[0080] The reservoir 24 in the exemplary embodiment is a cartridge or syringe as shown in FIG. 4. The pump 20' includes a control circuit 36, a user interface 40, a reader 50, and an injector assembly 46, which may be configured as described above. The pump 20' includes a pumping assembly 33 having an actuator 35 and a plunger 34. The actuator 35, controlled by the control circuit 36, is configured to cause the plunger 34 to translate a seal 76 of the container 75 within the container body 75 to expel the medicament 22 from the container 75. The medicament is driven through the fluid pathway outlet 32 ​​to the injector assembly 46, which delivers the medicament to the patient. The actuator 35 of the pumping assembly may be any suitable actuator, such as, but not limited to, a mechanical actuator, an electromechanical actuator, a pneumatic actuator, or a hydraulic actuator.

[0081] Although the above examples describe the data storage component 48 as storing data such as volume, dosage, and delivery rate (or flow rate), examples of the present disclosure are not so limited. In various embodiments, the data stored by the reservoir data storage component can store any suitable data for configuring the operating parameters of the drug delivery system, and the control circuitry 36 can be configured to set the operating parameters of the drug delivery system to a first value based on the configuration data, such that when the pump assembly drives drug from the reservoir, the drug delivery system operates with the operating parameters set to the first value. In this manner, the data storage component can store information usable to configure the pump hardware and software for preferred delivery of its associated drug. It will be appreciated that after setting the operating parameters to a first value, the control circuitry 36 can be configured to change the operating parameters of the drug delivery system to one or more values ​​based on the configuration data, and the drug delivery system can further operate with the operating parameters set to one or more over values. Of course, the data storage component can store configuration data for configuring two or more operating parameters, such as a plurality of operating parameters, and the control circuit 36 ​​can be configured to set the operating parameters of the drug delivery system based on the configuration data, such that when the pump assembly drives drug from the reservoir, the drug delivery system operates with the set operating parameters.

[0082] The control circuitry can be configured to set an operating parameter of the drug delivery system by changing the operating parameter of the drug delivery system from a different value to a first value. However, in some examples, changing the operating parameter may not be necessary. For example, the control circuitry can check the value of the operating parameter of the drug delivery system, and if the value of the operating parameter matches the configuration data, the control circuitry can set the value of the operating parameter by verifying the value without changing the value of the operating parameter.

[0083] In some examples, such as multiple dose or multiple drug dosing regimens, the drug delivery system can include a second reservoir configured to accommodate a second drug therein, the second reservoir including a second data storage component. The second drug can be the same drug as the first drug or a different drug. The reader can be configured to read second configuration data from the second data storage component for configuring operating parameters of the drug delivery system. The control circuitry can further be configured to set the operating parameters of the drug delivery system to a second value based on the configuration data, such that when the pump assembly drives the drug from the second reservoir, the drug delivery system operates with the operating parameters set to the second value.

[0084] The configuration data may relate to a volume, dosage, or delivery or flow rate as described above, or may relate to any other suitable operating parameter. For example, the configuration data may relate to an identification of the medication in the reservoir. The control circuitry 36 may use the identification information to verify whether the medication in the reservoir is a counterfeit or unauthorized medication. For example, prior to the start of delivery, the pump may engage a data storage component in a “challenge-response” authentication process to identify the use of a counterfeit or unauthorized medication. The control circuitry 36 may be configured to set operating parameters of the medication delivery system based on detection of a counterfeit or unauthorized medication to (i) shut down the medication delivery system so that it cannot deliver the medication, and / or (ii) provide an alarm or warning to the operator of the counterfeit or unauthorized medication.

[0085] The control circuitry 36 may use the identification information in a multi-sequence delivery to verify whether the drugs loaded into the pump are loaded in the proper sequence. In such an example, the control circuitry 36 may be configured to set operating parameters of the drug delivery system based on detection of an improper drug sequence to (i) shut off the drug delivery system so that it is unable to deliver the drug, and / or (ii) provide an alarm or warning to an operator of the improper drug sequence.

[0086] The configuration data may relate to an expiration date of the medication in the reservoir. In such an example, the control circuit 36 ​​may be configured to set operating parameters of the medication delivery system based on detection of an expired medication to (i) shut down the medication delivery system so that it cannot deliver the expired medication, and / or (ii) provide an alarm or warning to an operator about the expired medication.

[0087] The configuration data can relate to a desired delivery force used to deliver the drug stored in the reservoir, and the pump's operating parameters (e.g., motor parameters) can be set to deliver the drug using the desired delivery force. For example, a high viscosity drug may be more difficult to deliver at a particular flow rate than a low viscosity drug, and the high viscosity drug may need to be dispensed from the pump using a higher force (e.g., exerting a higher force on the pump's plunger 34), a higher pressure in the pumping chamber 28, and / or more power from the pump's power supply 420. Thus, the control circuitry 36, which monitors the pump's operation and detects faults, can be programmed with different sets of thresholds in response to the configuration data read from the data storage component to evaluate proper pump operation during delivery of a high viscosity drug. These thresholds can be preprogrammed in the data storage component such that they can be implemented in the pump's hardware and software prior to the initiation of drug delivery. Alternatively, these thresholds can be preprogrammed in the control circuitry 36, and the control circuitry 36 can select the appropriate thresholds based on the configuration data (e.g., drug identity) stored on the data storage component 48.

[0088] As a specific example, the desired plunger force range during delivery of a low viscosity drug may be 10-15 N, and forces outside this range would be considered abnormal operation and result in an alarm. In comparison, the desired plunger force range for a higher viscosity drug may be 20-30 N. Each data storage component may be preprogrammed with data regarding the desired operating parameters for the associated drug, and the control circuitry 36 may reconfigure the pump for the desired operating range. The control circuitry 36 may reconfigure the pump by changing software thresholds and / or selecting different software algorithms. The control circuitry 36 may also reconfigure the hardware by modifying settings of various hardware components, such as (without limitation) digital potentiometers, microwave switching circuits, sensors, transducers, and / or amplifiers.

[0089] The configuration data may relate to a desired temperature of the medication upon delivery. For example, a particular medication may require refrigerated storage and require the medication to be warmed to a particular temperature before the pump begins delivery. The temperature information may be stored on a data storage component, and the pump may be equipped with a temperature measurement component, such as a thermistor. The control circuitry 36 may be configured to detect the temperature of the medication and set operating parameters of the medication delivery system based on the detection of the medication temperature. In some examples, the control circuitry 36 may (i) shut down the medication delivery system until the medication is warmed to the desired temperature, and / or (ii) provide an alarm or warning to the operator that the medication has not been warmed to the desired temperature.

[0090] The configuration data can store information that the control circuitry 36 uses to modify the pump's user interface behavior according to an associated medication. For example, upon reading the data storage component, the pump's display can inform the user of special instructions / alerts associated with a particular medication and / or instructions on how to prepare the next medication in a manually performed multi-vial sequence. Similarly, the control circuitry 36 can coordinate the operation of other user interface devices, such as (without limitation) a tactile buzzer, speaker, piezoelectric transducer, and / or LEDs, to generate special alerts and warnings associated with the delivery of a particular medication or sequence of medications.

[0091] 8 and 9 show another embodiment of a pump 100 configured to deliver a liquid medicament 148 to a patient. The pump 100 of FIGS. 8 and 9 is generally constructed and used similarly to the pump 20 of FIG. 1. The pump 100 is configured to engage a therapeutic substance reservoir 132. The reservoir 132 can have any of a variety of configurations similar to those described above with respect to the reservoir 24 of FIG. 1. Within the pump 100 is a sterile fluid pathway 122 for delivering the medicament 148 to a patient wearing the pump 100. The sterile fluid pathway 122 has a conduit 126 at an upstream end 124 of the sterile fluid pathway 122 and an injection assembly (also referred to herein as an "injector assembly") 130 at a downstream end 128 of the sterile fluid pathway 122.

[0092] The pump 100 also includes a control circuit 138, a user interface (UI) 150 operably coupled to the control circuit 138 and configured to provide information to a user of the pump 100, and a reader 136 operably coupled to the control circuit 138 and configured to read the data storage component 134 of the reservoir 132. The user interface 150 can have any of a variety of configurations, similar to those described above with respect to the user interface 40 of FIG. 1. The data storage component 148 and the reader 136 can each have a variety of configurations, similar to those described above with respect to the data storage component 48 and the reader 50 of FIG. 1. The control circuit 136 is configured to control the administration of the medication 148 from the pump 100 according to a dosing regimen, similar to those described above with respect to the control circuit 36 ​​of FIG. 1. Thus, the control circuit 136, e.g., a processor thereof, is configured to establish at least one of the one or more variable parameters of the algorithm based on data received from the reader 136, such that the data is based at least in part on data stored on the data storage component 134 of the reservoir 132.

[0093] The pump 100 and the reservoir 132 are configured to engage with one another, as shown by the reservoir 132 being moved into the housing 110 of the pump 100 in the direction of the arrow 133 shown in FIG. 8. Thus, the reservoir 132 is configured to be inserted into the pump 100. Similar to that described above with respect to the pump 20 of FIG. 1, the reservoir 132 may be non-removably received within the pump 100, or may be removably and replaceably received within the pump 100. The conduit 126 is configured to be driven into the reservoir 132 when the pump 100 and the reservoir 132 are engaged with one another, as shown in FIG. 9, thereby establishing fluid communication between the reservoir 132 and the sterile fluid pathway 122. In embodiments in which the data storage component 134 is located on top of the reservoir 132 through which the conduit 126 passes, the conduit 126 may be configured to pass through the data storage component.

[0094] Once fluid communication is established between the reservoir 132 and the sterile fluid pathway 122 and the control circuit 138 has adjusted the dosing regimen based on the data received from the reader 136, the control circuit 138 is configured to drive the pump assembly 140 of the pump 100 to draw the medication 148 from the reservoir 132 and deliver the medication 148 to the patient via the injection assembly 130, in a manner similar to that described above with respect to the control circuit 36 ​​and injection assembly 46 of FIG. 1.

[0095] The data storage component 134 is located to the side of the reservoir 132 in this illustrated embodiment, although as noted above, the reservoir 132 may include the data storage component 134 at another location. The reader 136 is positioned within the pump 100 such that it is configured to align with the data storage component 134 when the reservoir 132 is housed within the pump 100, as shown in FIG.

[0096] Generally, in embodiments in which the data storage component includes an NFC tag, the data storage component of a reservoir received in the pump is located within the effective distance of the pump's reader. In this way, the reader can effectively read data from the NFC tag. In some embodiments, the reader is within the effective distance of the pump regardless of the alignment of the reservoir relative to the pump. For example, if the data storage component is located at the top of the reservoir or at the bottom of the reservoir (e.g., as shown in FIG. 3 where the NFC tag 72 is located at the bottom of the vial 70), the rotational alignment of the reservoir relative to the pump does not affect the effective distance of the reader from the data storage component. In other embodiments, the alignment of the reservoir relative to the pump may affect the ability of the reader to effectively read the data storage component. In such embodiments, minimizing the distance between the pump's reader and the reservoir's data storage component may help ensure that the reader is within the effective distance to properly read data from the data storage component.

[0097] An exemplary embodiment has the pump reader and reservoir data storage components at a minimum distance from one another, substantially coaxially aligned, vertical in the same plane, have windings of substantially the same shape and size, and have a maximum number of electromagnetic field lines generated by the reader, e.g., by its antenna, passing through the data storage component, e.g., its antenna. Those skilled in the art will understand that the axes may not be precisely coaxially aligned, the planes may not be precisely vertical, and the sizes and shapes may not be precisely the same, but may nevertheless be considered substantially coaxially aligned, substantially vertical, or substantially the same size and shape due to any number of factors, such as manufacturing tolerances and sensitivity of measurement equipment.

[0098] 10 illustrates one embodiment of the relative positioning of a data storage component's NFC tag antenna 200 that is substantially coaxially aligned with, perpendicular to, and of substantially the same shape and size as, a reader's NFC reader antenna 202. The greatest number of electromagnetic field lines 204 generated by the NFC reader antenna 202 pass through the NFC tag antenna 200 at a minimum distance D from the NFC reader antenna 202. The data storage component in this illustrated embodiment also includes an NFC tag chip 206 operably coupled to the NFC tag antenna 200, and the reader in this illustrated embodiment also includes a reader chip 208 operably coupled to the NFC reader antenna 202. FIG. 11 illustrates a comparison of the NFC tag antenna 200 and NFC reader antenna 202 of FIG. 10, with less desirable positions and orientations of the NFC tag antennas 200a, 200b, 200c, 200d, 200e relative to the NFC reader antenna 202.

[0099] The pump and reservoir configured to be received within the pump can include cooperating alignment features configured to cooperate to optimally position the reader and data storage components relative to one another, thereby facilitating optimal performance of the reader of the pump and the data storage components of the reservoir. The cooperating alignment features can have a variety of configurations.

[0100] 12 shows an embodiment in which a pump 300 includes a female alignment feature 302 configured to engage a male alignment feature 304 of a reservoir 306, which in this illustrated embodiment is a syringe but may be of another type as described herein. In other embodiments, the pump 300 can include a male alignment feature and the reservoir 306 can include a female alignment feature. Although this illustrated embodiment includes a single male alignment feature 302 and a single female alignment feature 304, another equivalent number of cooperating male and female alignment features can be used.

[0101] The alignment features 302, 304 are configured to slidably engage when the reservoir 306 is inserted into the pump 300. If the alignment features 302, 304 do not engage with one another, e.g., if the male alignment feature 304 does not seat within the female alignment feature 302, the reservoir 306 cannot be inserted into the pump 300 because the space for the reservoir 306 in the pump 300 is too small for the reservoir 306 to be inserted into the pump 300. Thus, the reservoir 306 can only be inserted into the pump 300 in a predetermined orientation relative to the pump 300. Thus, the data storage component 308 of the reservoir 306, e.g., its antenna, will be positioned in an effective location relative to the reader 310, e.g., its antenna, of the pump 300 with the reservoir 306 received within the pump 300, as shown in FIG. The data storage component 308 is in the cylindrical side of the reservoir 306 in this illustrated embodiment, however, the cooperating alignment features can be used with the data storage component of the reservoir in another location as well.

[0102] As mentioned above, in some embodiments, the pump's reader may include a multiplexed reader, where the reservoir's data storage component has multiple valid positions relative to the reader. In such embodiments, it is not necessary to use a cooperative alignment mechanism. Using the reservoir 306 embodiment of FIG. 12 as an example, FIG. 13 illustrates an embodiment of a pump 312 that includes a multiplexed reader that includes multiple reader antennas 314. FIG. 13 illustrates the reservoir 306 inserted into the pump 312.

[0103] FIG. 14 illustrates another embodiment of a pump 400 configured to deliver a medication to a patient. The pump 400 of FIG. 14 is generally configured and used similarly to the pump 20 of FIG. 1. The pump 400 includes a reservoir 402 configured to contain therein a liquid medication to be delivered from the pump 400. The reservoir 402 can have a variety of configurations, as discussed herein. The pump 400 also includes a pumping assembly 404 configured to cause dispensing of the medication contained within the reservoir 402 so that the medication may be delivered to the patient. The pump 400 also includes an injector assembly including an infusion line 406, e.g., a needle or cannula, configured to be removably attached to the patient. The medication is delivered from the reservoir 402 upon actuation of the pumping assembly 404 via the infusion line 406. Thus, the pump 400 in the illustrated embodiment of FIG. 14 is configured as an "off-body" pump. In some embodiments, the pump 400 is a single-use pump, where the pump 400 is only used until the infusion line 406 is disconnected from the patient. In other embodiments, the pump 400 is a multi-use pump, where the pump 400 is reusable with different infusion lines 406.

[0104] The pump 400 also includes a user interface 408 configured to provide information to a user of the pump 400, and a reader 410 configured to read data from a data storage component 412 of the reservoir 402. Each of the user interface 408, the reader 410, and the data storage component 412 can have a variety of configurations, as described herein. The pump 400 and the reservoir 402 can include cooperating alignment mechanisms, as described herein.

[0105] The pump 400 also includes a control circuit 414 that includes a processor 416 and a memory 418. The processor 416 is operatively coupled to the memory 418, the user interface 408, the reader 410, and the pumping assembly 404. The operation of the pumping assembly 404 is controlled by the processor 416.

[0106] The pump 400 also includes a power supply 420 configured to provide power to any components of the pump 400 that require power to operate, such as the pumping assembly 404, the processor 416, and the user interface 408.

[0107] The reservoir 402, pumping assembly 404, user interface 408, power source 420, and control circuitry 414 are located within a housing (also referred to herein as the "body" of the pump) 422 of the pump 400. The infusion line 406 is located partially within the housing 422 and extends from the housing 422 for penetration to a patient. The infusion line 406 may be fixedly positioned partially inside the housing 422 and partially outside the housing 422, as shown in FIG. 14, or the infusion line 406 may be movable, for example, under the control of the circuitry 414, from an initial position completely inside the housing 422 to a delivery position partially inside the housing 422 and partially outside the housing 422.

[0108] Figure 15 illustrates another embodiment of a pump 500 that is configured to be worn by a patient and to deliver a liquid medicament to the patient. The pump 500 of Figure 15 is generally constructed and used similarly to the pump 20 of Figure 1, and includes, for example, a housing 502, a user interface 504, a reservoir 506 configured to contain therein a liquid medicament to be delivered from the pump 500, a pumping assembly 508 configured to cause dispensing of the medicament contained within the reservoir 506, an injector assembly 510 configured to deliver the medicament into the patient, a reader 512 configured to read a data storage component 514 of the reservoir 506, a plunger 516 configured to slide within the pump chamber, and a control circuit 518 operably connected to the reader 512, the user interface 504, and the pumping assembly 508.

[0109] The pump 500 also includes a removable backing or label 520 and a depressible button 522. The backing or label 520 is configured to be removed from the housing 502 of the pump 500 to expose a patient-attachable adhesive to allow the pump 500 to be removably attached to a patient. The button 522 is configured to be pressed by a user to initiate operation of the pump 500 and deliver medication to the patient according to a stored dosing regimen.

[0110] The user interface 504 in this illustrated embodiment includes a number of lights arranged circumferentially around the button 522. The lights can be illuminated to provide various information to the user. The lights include a number of lights, e.g., two, three, four, five, etc., in this illustrated embodiment, but can also include a single light. Instead of or in addition to surrounding the button 522, the light(s) can be arranged, for example, in a row. Various embodiments of lights and light illumination to provide information are further described, for example, in the aforementioned WO 2021 / 124002 brochure, entitled "Liquid Drug Pumps Including User Feedback Indicating Pump Orientation," published June 24, 2021, supra.

[0111] The present disclosure has been described above for illustrative purposes only within the context of the entire disclosure provided herein. It will be understood that modifications may be made within the spirit and scope of the claims without departing from the overall scope of the present disclosure. All publications and references cited herein are expressly incorporated herein by reference in their entirety for all purposes.
