Abstract

Method and apparatus for charging a power supply unit such as a rechargeable battery for use in data monitoring and management system using the ESD protection circuitry of the existing electrode contacts including guard contact and counter electrode thereby reducing system cost, complexity, and any unprotected battery contacts exposed for potential contamination is provided.

Claims

1. An apparatus including a rechargeable power in a glucose monitoring system comprising:

a sensor configured to detect one or more glucose level of a patient;

a transmitter unit configured to receive the one or more detected glucose levels, and to transmit one or more data corresponding to the detected one or more glucose levels; and

a receiver unit configured to receive the transmitted one or more measured glucose data;

wherein the transmitter unit includes a rechargeable battery,

wherein the sensor includes a plurality of sensor contacts, each of the plurality of sensor contacts coupled to the transmitter unit, and further

wherein a pair of the plurality of sensor contacts coupled to the transmitter unit is configured to receive a predetermined power signal to charge the rechargeable battery of the transmitter unit.

2. The apparatus of claim 1 wherein the pair of plurality of sensor contacts configured to receive a predetermined power signal includes a guard contact and a counter electrode.

3. The apparatus of claim 1 wherein the predetermined power signal includes a current signal from a power source.
