Abstract
Methods and systems for determining elapsed sensor life in medical systems, and more specifically continuous analyte monitoring systems.
Claims20
A method, comprising:
- providing a signal associated with initiation of an analyte sensor, the analyte sensor for monitoring analyte level;
- providing a count, wherein the count is temporally associated with the signal associated with the initiation of the analyte sensor;
- periodically incrementing the count;
- storing the count temporally associated with the signal associated with the initiation of the analyte sensor, wherein when sensor life of the initiated analyte sensor has not expired and a system failure is detected, continuing use of the initiated analyte sensor based at least in part on the stored count;
- providing a new sensor count;
- and
- incrementing the new sensor count only when a new sensor is first initiated.
4 more elements
A data processing device, comprising:
- a first counter configured to incrementally count;
- a data communication unit;
- a data processing section coupled to the data communication unit and the first counter, the data processing section configured to determine an elapsed life of an analyte sensor;
- wherein when a device failure is detected and the determined elapsed life indicates that analyte sensor life has not expired, continuing use of the analyte sensor based at least in part on the first counter configured to incrementally count;
- and
- a new sensor counter coupled to the data processing section and configured to increment a new sensor count only when a new sensor is first initiated.
3 more elements
A method of operating an analyte monitoring system comprising:
- providing a signal associated with initiation of an analyte sensor;
- providing a first counter to count incrementally;
- and
- providing a second counter to incrementally count by one only when a new sensor is first initiated;
- wherein when sensor life of the initiated analyte sensor has not expired and a system failure is detected, continuing use of the initiated analyte sensor based at least in part on the first counter and the second counter.
