Abstract
A glucose monitoring system, includes a glucose sensor strip or package of strips. The strip includes a substrate and a glucose monitoring circuit that has electrodes and a bodily fluid application portion of selected chemical composition. An antenna is integrated with the glucose sensor strip. A RFID sensor chip is coupled with the glucose sensor strip and the antenna. The chip has a memory containing digitally-encoded data representing calibration and/or expiration date information for the strip.
Core Innovation
A glucose monitoring system includes an electrochemical glucose sensor strip having a substrate and a glucose monitoring circuit with multiple electrodes and a bodily fluid application portion of selected chemical composition. The glucose sensor strip integrates an antenna and is coupled to an RFID sensor chip, and the RFID sensor chip includes a memory containing digitally encoded data representing expiration date information for the sensor and/or calibration information for the sensor.
A glucose meter includes an RFID reader integrated with the glucose meter and having a port for inserting the glucose sensor strip and measuring a glucose level. The RFID reader is configured to read, program or power the RFID sensor chip, or combinations thereof, and automatically reads expiration date data and/or calibration data by RF communication when the strip is inserted into the port.
The disclosed implementations include digitally encoded memory contents beyond expiration date information, including lot number, manufacture date, strip type and/or other sensor type, calibration code and calibration data, and optional chemical composition information. Antenna forms are integrated with the glucose sensor strip, including loop antenna and perimeter loop configurations, with the RFID sensor chip coupled to the antenna on a substrate.
The documented package-level embodiments include a package of glucose sensor strips with an antenna integrated with the package and an RFID sensor chip storing digitally encoded expiration date information for the strips.
Claims Coverage
The independent claims cover glucose monitoring systems with four inventive features: strip-level RFID expiration-date memory, strip-level RFID calibration-information memory, automatic RFID reading of expiration-date data by a glucose meter, and automatic RFID reading of calibration data by a glucose meter. Additional independent coverage includes package-level embodiments for expiration-date and calibration-information variants.
A glucose sensor strip with integrated antenna and RFID expiration-date memory
A glucose monitoring system comprising a glucose sensor strip including a substrate and a glucose monitoring circuit with multiple electrodes and a bodily fluid application portion of selected chemical composition; an antenna integrated with the glucose sensor; and an RFID sensor chip coupled with the glucose sensor and the antenna, where the chip comprises a memory containing digitally-encoded data representing expiration date information for the sensor.
Automatic RFID reading of expiration-date data by a glucose meter
A glucose monitoring system where a glucose meter includes an RFID reader component integrated with the glucose meter and having a port for inserting the glucose sensor strip and measuring a glucose level; the RFID reader is for reading, programming or powering the chip, or combinations thereof; and expiration date data is automatically read from the RFID sensor chip by the RFID reader by RF communication when the strip is inserted into the port of the glucose meter.
A glucose sensor strip with integrated antenna and RFID calibration-information memory
