Abstract

An analyte monitoring system and method. The analyte monitoring system may include an analyte sensor and a transmitter. The analyte sensor may include an indicator element that exhibits one or more detectable properties based on an amount or concentration of an analyte in proximity to the indicator element. The transmitter may be configured to receive measurement information from the analyte sensor. The transmitter may be configured to assess in real time a performance of the analyte sensor based on at least the measurement information. The transmitter may be configured to determine whether the performance of the analyte sensor is deficient based at least on the assessed performance of the analyte sensor. The transmitter may be configured to predict an amount of time remaining before the performance of the analyte sensor becomes deficient based on at least the assessed performance of the analyte sensor.

Dependent claims

An analyte monitoring system comprising:

an analyte sensor including an indicator element that exhibits one or more detectable properties based on an amount or concentration of an analyte in proximity to the indicator element;
and
a transmitter comprising a sensor interface device and a controller, and the transmitter is configured to:
(i) use the sensor interface device to receive measurement information from the analyte sensor,
(ii) use the controller to use at least the received measurement information to calculate two or more measures selected from the group consisting of:
(a) a responsiveness of the indicator element of the analyte sensor to changes in an amount or concentration of the analyte in proximity to the indicator element,
(b) a strength of the one or more detectable properties exhibited by the indicator element of the analyte sensor,
(c) an accuracy of the analyte sensor, and
(d) a response of a body in which the analyte sensor is located to the analyte sensor,
(iii) use the controller to calculate a minimum value of the calculated two or more measures,
(iv) determine whether a performance of the analyte sensor is deficient based at least on the calculated minimum value, and
(v) predict an amount of time remaining before the performance of the analyte sensor becomes deficient based on at least the calculated minimum value.
