Abstract

The present invention includes analyte measurement systems, analyte measurement meters, analyte testing devices, cartridges thereof and integrated circuits for use therewith, and further includes methods related to the use of the integrated circuits and, in certain embodiments, to the counting or tracking of parameters related to the cartridges and analyte test devices.

Claims

1. A method of tracking at least one degradation parameter for analyte testing devices dispensable from within a sealed cartridge having an integrated circuit coupled thereto and installable within an analyte measurement meter communicable therewith, the method, upon installation of the cartridge within the meter, comprising:

communicating with the integrated circuit and accessing the at least one degradation parameter, the at least one degradation parameter comprising a first degradation parameter comprising cumulative time the analyte testing devices are exposed to ambient air and a second degradation parameter comprising cumulative time the analyte testing devices are exposed to desiccated conditions, wherein the cartridge comprises a desiccating material; and

updating the at least one degradation parameter based on at least one type of action performed by the meter, the at least one type of action comprising a first type of action comprising temporarily unsealing the cartridge and a second type of action comprising receiving the cartridge in the meter.

2. The method of claim 1, further comprising decrementing a parameter stored on the integrated circuit representing the number of analyte testing devices contained in the cartridge.

3. The method of claim 1, wherein the updating comprises summing at least two degradation parameters.

4. The method of claim 1, further comprising calibrating the meter according to calibration parameters stored on the integrated circuit.

5. The method of claim 1, further comprising creating a modifiable log of information about the cartridge and the analyte testing devices contained therein.

6. The method of claim 1, further comprising commencing the timing of expiry of the analyte testing devices.

7. The method of claim 1, further comprising storing a unique meter identifier onto the integrated circuit.

8. The method of claim 1, further comprising storing a unique cartridge identifier onto the meter.
