TRANSCUTANEOUS ANALYTE SENSORS, APPLICATORS THEREFOR, AND ASSOCIATED METHODS
First Claim
1. A method of applying an on-skin sensor assembly to a host, wherein the on-skin sensor assembly comprises a housing secured to the applicator, wherein the housing is configured to receive an electronics unit, comprising:
- attaching an applicator to a skin of a host, the applicator comprising a sensor insertion mechanism, a trigger, and a base;
inserting the electronics unit into the housing, wherein the electronics unit is configured to generate analyte information based on a signal from a sensor;
activating the trigger, thereby causing the sensor insertion mechanism to insert a sensor into the host, to secure the electronics unit to the housing such that the sensor electrically contacts the electronics unit, and to cause the housing to detach from the base; and
removing the applicator from the skin of the host, whereby an on-skin sensor assembly comprising the housing, the electronics unit, and the inserted sensor remains on the skin of the host.

Abstract
The present embodiments relate generally to systems and methods for measuring an analyte in a host. More particularly, the present embodiments provide sensor applicators and methods of use with pushbutton activation that implant the sensor, withdraw the insertion needle, engage the transmitter with the housing, and disengage the applicator from the housing, all in one smooth motion. Some embodiments contemplate engagement of the transmitter with the housing after release of the applicator.

12. A method of applying an on-skin sensor assembly to a host, comprising:
-
attaching an applicator to a skin of a host, the applicator comprising a sensor insertion mechanism, a trigger, and a base; a housing secured to the applicator, wherein the housing is configured to receive an electronics unit; activating the trigger, thereby causing the sensor insertion mechanism to insert a sensor into the host and to cause the housing to detach from the base; removing the applicator from the skin of the host, whereby the housing and the inserted sensor remain on the skin of the host; and inserting the electronics unit into the housing, wherein the electronics unit is configured to generate analyte information based on a signal from the sensor, and wherein the electronics unit is secured to the housing such that the sensor electrically contacts the electronics unit, whereby an on-skin sensor assembly comprising the housing, the electronics unit, and the inserted sensor is obtained. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
