Abstract

A portable apparatus for measuring a glucose level of a user having: a card-like member; a processor within the card-like member; at least one glucose sensor comprising a reagent, the glucose sensor generating a signal indicative of a measured glucose level upon application of a blood sample to the glucose sensor, wherein the glucose sensor is fixed to the card-like member and operably coupled to the processor; and at least one cover alterable between a first position in which the glucose sensor is covered and a second position in which the glucose sensor is exposed for use.

Claims

1. A portable apparatus for measuring a glucose level of a user comprising:

a card-like member;

a processor within the card-like member;

at least one glucose sensor comprising a reagent, the at least one glucose sensor generating a signal indicative of a measured glucose level upon application of a blood sample to the at least one glucose sensor, wherein the at least one glucose sensor is fixed to the card-like member and operably coupled to the processor; and

a calibration glucose sensor fixed to the card-like member so as to be unusable by the user and wherein calibration data unique to the at least one glucose sensor is generated by the calibration glucose sensor.

2. A portable apparatus for measuring a glucose level of a user comprising:

a card-like member;

a processor within the card-like member;

at least one glucose sensor comprising a reagent, the at least one glucose sensor generating a signal indicative of a measured glucose level upon application of a blood sample to the at least one glucose sensor, wherein the at least one glucose sensor is fixed to the card-like member and operably coupled to the processor;

a memory device within the card-like member and operably coupled to the processor, the memory device comprising pre-stored calibration data unique to the at least one glucose sensor; and

a calibration glucose sensor fixed to the card-like member so as to be unusable by the user, the calibration glucose sensor being from the same lot as the at least one glucose sensor, and wherein the calibration data unique to the at least one glucose sensor is generated by the calibration glucose sensor and stored in the memory device.

3. The apparatus of claim 2 wherein the calibration glucose sensor is embedded within the card-like member.

4. The apparatus of claim 2 wherein the calibration data unique to the at least one glucose sensor is generated by the calibration glucose sensor by:

applying a test solution having a known glucose level to the calibration glucose sensor, the calibration glucose sensor generating a test signal indicative of a measured glucose level of the test solution; and

the processor receiving the test signal and generating the calibration data for storage on the memory device.
