Abstract

The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.

Claims

1. A sensor system for measuring an analyte in a host, the system comprising:

a sensor configured to measure an analyte concentration in a host;

sensor electronics operably connected to the sensor, wherein the sensor electronics are configured to produce a signal associated with the analyte concentration in the host; and

a receiver configured to receive transmissions from the sensor electronics and to display sensor data for at least one sensor system, wherein the receiver is programmed to confirm disconnection of the sensor prior to initialization of another sensor system.

2. The sensor system of claim 1, wherein the receiver is configured to identify a sensor insertion.

3. The sensor system of claim 1, wherein the sensor electronics is programmed with an identification key comprising sensor information.

4. The sensor system of claim 1, wherein the sensor electronics are releasably attachable to a housing, and wherein the sensor system is configured to render the sensor system inoperative by disabling the sensor upon release of the sensor electronics from the housing.

5. A sensor system for measuring an analyte in a host, the system comprising:

a sensor configured to measure an analyte concentration in a host;

sensor electronics operably connected to the sensor, wherein the sensor electronics are configured to produce a signal associated with the analyte concentration in the host; and

a receiver configured to receive transmissions from the sensor electronics and to display sensor data for at least one sensor system, wherein the sensor electronics is programmed to transmit information indicative of sensor insertion, and wherein the receiver is programmed to confirm sensor insertion prior to initialization of a sensor system.

6. The sensor system of claim 5, wherein the receiver is configured to identify a sensor insertion.

7. The sensor system of claim 5, wherein the sensor electronics is programmed with an identification key comprising sensor information.
