First Claim
Patent Images
1. An analyte measuring system, the system comprising:
- a mounting unit adapted for mounting on the skin of a host;
an electronics unit detachably connectable to the mounting unit;
a sensor for measuring a level of the analyte comprising an in vivo portion for insertion through the skin at an exit site of the host and an ex vivo portion connected to the mounting unit, wherein the sensor is operably connected to the electronics unit when the electronics unit is detachably connected to the mounting unit; and
a communication station for receiving and processing analyte measurements received from the electronics unit, wherein the mounting unit comprises an opening configured to releasably receive the electronics unit therein, and wherein the electronics unit and the mounting unit each comprise at least one electrical contact, and wherein each of the at least one electrical contacts are protected from moisture by an elastomeric sealing member that fits in the mounting unit.
