METHOD OF AND SYSTEM FOR STABILIZATION OF SENSORS

摘要

A blood glucose sensing system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes stabilization circuitry. The stabilization circuitry causes a first voltage to be applied to one of the electrodes for a first timeframe and causes a second voltage to be applied to one of the electrodes for a second timeframe. The stabilization circuitry repeats the application of the first voltage and the second voltage to continue the anodic-cathodic cycle. The sensor electronics device may include a power supply, a regulator, and a voltage application device, where the voltage application device receives a regulated voltage from the regulator, applies a first voltage to an electrode for the first timeframe, and applies a second voltage to an electrode for the second timeframe.

主权项

1. A method of stabilizing a glucose sensor having a plurality of electrodes for measuring a patient's glucose level, the method comprising:
(a) applying a voltage to one of the plurality of electrodes for a first predetermined time period, said voltage being between 0.535 volts and 1.07 volts; (b) waiting a second predetermined time period with no voltage application; (c) repeating, for one or more iterations, a cycle of performing step (a) followed by step (b) until a measured electrical characteristic of the sensor meets a predetermined criterion which indicates sensor stabilization; (d) measuring the patient's glucose level with the electrodes; and (e) beginning to use said measured glucose level after the sensor is stabilized.
