Abstract
Systems, devices and methods are provided for the integration of an analyte data reader and a medication delivery device. The integrated device can include a medication delivery portion, wireless communications circuitry configured to receive data indicative of an analyte level, and electronics. The integrated device can also include one or more near-field communication (NFC) antennas. Example embodiments of adverse condition protection features of the integrated device are also provided.
Core Innovation
The invention relates to an integrated medication delivery device that wirelessly receives analyte-level data from a sensor control device and determines a parameter associated with an analyte level. The device includes a housing with a cap, a medication delivery portion contained within the housing, and electronics contained within the housing. The electronics include wireless communication circuitry configured to receive data indicative of an analyte level from the sensor control device, one or more near-field communication (NFC) antennas coupled to the wireless communication circuitry, and one or more processors with memory including instructions to determine a parameter associated with the analyte level based at least in part on the received data.
The integrated device architecture emphasizes coupling the one or more NFC antennas to the cap and using NFC communication to obtain sensor data from the sensor control device. Configurations include NFC antennas arranged on the cap and/or positioned on housing exterior or interior features, including flat-side pen cap antenna placement, dual antennas on different housing portions or curved surfaces, and configurations that separate antenna and electronics using an enlarged end portion. Additional refinements describe deployable, flexible, or pivoting antennas, and multi-antenna arrangements with non-overlapping portions on exterior surfaces.
The background and summary information indicate a problem of enabling analyte-level data transfer from an on-body sensor control device to a medication delivery device to support computing or control of medication delivery. The described solution includes protective and control features tied to adverse conditions, including low-glucose insulin lockout and warnings and cap-removal detection with lock-out mechanisms preventing unsafe operation, with optional manual override. The partial content also describes NFC power-scheme concepts using burst transmission timing to reduce power consumption associated with energization of a passive NFC sensor control device.
Claims Coverage
The independent claim covers an integrated medication delivery device that receives analyte-level data via wireless communication, uses one or more cap-coupled NFC antennas and a user interface to initiate NFC communication with a sensor control device, and uses processors and memory instructions to determine a parameter associated with the analyte level. Across the dependent claims referenced in the partial content, the main inventive features narrow NFC communication initiation and handling, specify antenna placement and geometry relative to the cap and housing, and define the analyte-associated parameter as a medication delivery amount in at least one refinement.
Cap-coupled NFC antennas for analyte-level data transfer
One or more near-field communication (NFC) antennas coupled to the wireless communication circuitry, wherein the one or more NFC antennas are coupled to the cap.
User interface permits initiation of NFC communication
A user interface integrated with the medication delivery device and configured to permit initiation of an NFC communication with the sensor control device.
Determine parameter from received analyte-level data
Instructions that, when executed by the one or more processors, cause the one or more processors to determine a parameter associated with an analyte level based at least in part on the received data indicative of the analyte level.
Direct NFC protocol communication
The device is configured to directly communicate with the sensor control device using an NFC protocol.
Non-overlapping dual NFC antennas on exterior surface portions
One or more NFC antennas with a first NFC antenna on a first non-overlapping portion of the housing exterior surface and a second NFC antenna on a second non-overlapping portion of the housing exterior surface.
NFC antennas on interior surface of a cap cavity
One or more NFC antennas placed on an interior surface of a cavity in the cap.
Cylindrical rechargeable battery at cap end portion
A cylindrical rechargeable battery located at an end portion of the cap.
Parameter defined as medication delivery amount
The parameter tied to the analyte level is a medication delivery amount.
Overall, the claimed coverage centers on a medication delivery device that receives analyte-level data from a sensor control device, integrates cap-coupled NFC antennas and a user interface for NFC initiation, and computes a parameter associated with the analyte level using processors and memory instructions. Dependent features narrow NFC communication to direct NFC protocol handling, specify multi-antenna placement on non-overlapping exterior portions and/or on interior cap cavity surfaces, add a cylindrical rechargeable battery location at the cap end portion, and define the analyte-associated parameter as a medication delivery amount.
