Transcutaneous analyte sensor
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.
1. A method for inserting a transcutaneous analyte sensor in a host, the method comprising:
providing an assembly for inserting the transcutaneous analyte sensor into a host, wherein the assembly comprises an applicator releasably connected with a housing, wherein the housing is configured to be placed adjacent to the host's skin, and wherein the assembly further comprises the transcutaneous analyte sensor configured to be inserted into the host
inserting the transcutaneous analyte sensor into the host; and
connecting an electronics unit with the housing, wherein the applicator is capable of being released from the housing simultaneously with or subsequent to the connection of the electronics unit with the housing, wherein connecting the electronics unit with the housing comprises sliding the electronics unit into the housing.
2. The method of claim 1 , further comprising transferring information from the housing to the electronics unit in response to connection of the electronics unit with the housing.
3. The method of claim 1 , wherein the electronics unit is tapered to guide the sliding of the electronics unit into the housing.
4. The method of claim 1 , wherein the electronics unit has an architecture configured to self-align the electronics unit with the housing.
5. The method of claim 1 , wherein the connecting an electronics unit with the housing comprises forming a watertight seal around an electrical connection between the sensor and the electronics unit.
6. A method for inserting a transcutaneous analyte sensor in a host, the method comprising:
providing an assembly for inserting the transcutaneous analyte sensor into a host, wherein the assembly comprises an applicator releasably connected with a housing, wherein the housing is configured to be placed adjacent to the host's skin, and wherein the assembly further comprises the transcutaneous analyte sensor configured to be inserted into the host;
inserting the sensor into the host; and
connecting an electronics unit with the housing, wherein the applicator is capable of being released from the housing simultaneously with or subsequently to the connection of the electronics unit with the housing, wherein the applicator further comprises a safety latch mechanism configured to lock the sensor within the applicator prior to release of the safety latch mechanism, the method further comprising releasing the safety latch mechanism prior to inserting the sensor into the host.
7. The method of claim 6 , wherein the assembly is packaged with the safety latch mechanism in the locked position.
8. The method of claim 6 , wherein the safety latch mechanism is configured to be released by a pulling force.
9. The method of claim 6 , wherein the connecting an electronics unit with the housing comprises forming a watertight seal around an electrical connection between the sensor and the electronics unit.
