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.

First claim

What is claimed is:

1. An applicator system configured to insert a transcutaneous analyte sensor into a host, the applicator system comprising:
a housing configured for placement against a skin of the host;
a sensor configured for transcutaneous placement through the skin of a host; and
an applicator comprising applicator components, a trigger, a needle and a spring-loaded mechanism configured to insert the needle and the sensor into the host and subsequently retract the needle from the host, wherein the applicator components rotatingly engage one another with a continuous torque to insert the sensor into the host and subsequently retract the needle from the host, wherein the sensor is inserted automatically into the host to a predetermined depth responsive to actuation of the trigger.

2. The system of claim 1 , further comprising sensor electronics configured to be releasably electrically connected to the sensor.

3. The system of claim 2 , further comprising a sealing member configured to seal the electrical connection of the sensor with the sensor electronics from external moisture when the sensor electronics are releasably electrically connected to the sensor.

4. The system of claim 1 , wherein the applicator is releasably connected to the housing.

5. The system of claim 4 , wherein the releasable connection is automatic.

6. The system of claim 1 , wherein the housing comprises a body and an adhesive configured for adhering the body to the skin of the host.

7. The system of claim 6 , further comprising a vent hole located between the body and the adhesive.

8. The system of claim 6 , wherein the body is flexible.

9. An applicator system configured to insert a transcutaneous analyte sensor into a host, the applicator system comprising:
a housing configured for placement against a skin of the host;
a sensor configured for transcutaneous placement through the skin of the host; and
an applicator comprising applicator components, a spring loaded mechanism including a trigger, and a needle configured for inserting the sensor through the housing and into the skin of the host,
wherein the applicator components rotatingly engage one another to automatically, in response to the trigger being actuated, insert the needle and the sensor into the host and retract the needle from the host.

10. The system of claim 9 , further comprising sensor electronics configured to be releasably electrically connected to the sensor.

11. The system of claim 10 , further comprising a sealing member configured to seal the electrical connection of the sensor with the sensor electronics from external moisture when the sensor electronics are releasably electrically connected to the sensor.

12. The system of claim 9 , wherein the housing comprises a body and an adhesive configured for adhering the body to the skin of the host.

13. The system of claim 12 , further comprising a vent hole located between the body and the adhesive.

14. The system of claim 12 , wherein the body is flexible.
