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. A method for inserting a transcutaneous analyte sensor into a host using an applicator, the method comprising the steps of:
adhering a base of a mounting unit to a skin of a host before insertion of a transcutaneous sensor into the host;
pushing on a first component of an applicator for inserting the transcutaneous analyte sensor into the host, so as to insert an introducer and the sensor into the skin of the host by using a first springless force, wherein the pushing comprises pushing on a plunger; and
pulling on a second component of the applicator so as to retract the introducer from the skin of the host by using a second springless force, while leaving the sensor in the host;
wherein pushing is performed by a user, wherein the first component and the second component of the applicator are configured to interact so as to enable insertion of the sensor and retraction of the introducer.

2. The method of claim 1 , wherein the pulling step comprises pulling on a body portion of the second component of the applicator.

3. The method of claim 1 , wherein the first springless force or the second springless force is provided by a user's hand.

4. The method of claim 1 , wherein the applicator is configured to insert the sensor and retract the introducer responsive to a squeezing motion between a user's thumb and fingers.

5. The method of claim 1 , wherein the applicator is configured to sequentially insert the sensor and retract the introducer responsive to a squeezing motion between a user's thumb and fingers.

6. The method of claim 1 , wherein the user is the host.

7. An applicator for inserting a transcutaneous analyte sensor into a host, comprising:
a first component comprising a plunger; and
a second component;
wherein the applicator is configured and arranged such that pushing on the first component by a user inserts an introducer and a sensor into a host's skin after a base of a mounting unit has been adhered to the host's skin and pulling on the second component by a user retracts the introducer from the skin while leaving the sensor in the host, wherein pushing on the first component comprises pushing on the plunger, and wherein the first component and the second component are configured to interact so as to enable insertion of the sensor and retraction of the introducer; and
wherein the applicator is configured to insert the sensor by a first springless force directly provided by a user and retract the introducer substantially by a second springless force directly provided by the user.

8. The applicator of claim 7 , wherein the second component comprises a body portion, and wherein pulling on the second component comprises pulling on the body portion of the second component.

9. The applicator of claim 7 , wherein the first springless force and the second springless force is provided by a user's hand.

10. The applicator of claim 7 , wherein the applicator is configured to insert the sensor and retract the introducer responsive to a squeezing motion between a user's thumb and fingers.

11. The applicator of claim 7 , wherein the applicator is configured to sequentially insert the sensor and retract the introducer responsive to a squeezing motion between a user's thumb and fingers.

12. The applicator of claim 7 , wherein the user is the host.
