Abstract

Devices and methods relating to analyte sensor insertion devices and methods are provided.

Claims

1. A glucose sensor insertion system, the system comprising:

a mount configured to retain an inserter housing, the inserter housing being mateable with the mount and comprising a structure to carry a glucose sensor at least partially into a user'"'"'s skin; and

wherein mating the inserter housing and the mount together arms the system.

2. A self arming inserter comprising:

an inserter housing to be received in a mount;

a carrier supported by the inserter housing;

a sensor mounted on the carrier;

a driver which drives the carrier; and

wherein inserting the inserter housing in the mount arms the driver.

3. The self arming inserter according to claim 2, wherein the mount comprises a mount base and mount arms and the carrier comprises carrier arms.

4. The self arming inserter according to claim 3, wherein the carrier comprises a hook that engages a portion of the housing when driver is armed.

5. The self arming inserter according to claim 4, further comprising an actuator which actuates the driver and wherein actuating the actuator releases the driver.

6. The self arming inserter according to claim 5, wherein the driver comprises a spring and wherein arming the inserter comprises compressing the spring.

7. The self arming inserter according to claim 3, wherein the mount comprises an inserter hole through which the sensor passes when the carrier is driven by the driver.

8. The self arming inserter according to claim 3, wherein the mount is shiftable with respect to the housing after the mount is inserted into the housing.

9. The self arming inserter according to claim 2, wherein the driver drives the carrier at a speed of about 2 m/s or less.

10. The self arming inserter according to claim 3, further comprising an inserter tip which supports the sensor on the carrier.

11. The self arming inserter according to claim 2, wherein the sensor attaches to the mount after the driver drives the carrier.

12. The self arming inserter according to claim 3, wherein an adhesive is provided on a surface of the mount.

13. A method of arming an analyte sensor insertion system, the method comprising:

providing to a user an un-armed system that comprises an inserter housing and a mateable mount; and

mating the insertion housing and the mount together, whereby the mating arms the system.

14. A method of inserting an insertion tip using an inserter, the inserter comprising an inserter housing adapted to be received on a mount, a carrier supported by the inserter housing, an insertion tip mounted on the carrier, a driver which drives the carrier, and an actuator which actuates the driver, the method comprising:

placing the inserter housing on the mount so that arms of the mount contact arms of the carrier, thereby moving the carrier in a direction of arming the driver;

shifting the mount relative to the inserter housing so that the arms of the mount are unaligned with the arms of the carrier;

placing the inserter such that the mount is adjacent to a person'"'"'s skin; and

actuating the actuator so that the driver drives the carrier and the insertion tip is inserted into the person'"'"'s skin.

15. The method of claim 14, wherein a sensor is attached to the insertion tip and the sensor is also inserted into the person'"'"'s skin.

16. The method of claim 14, wherein the mount includes a base with a hole;

and

wherein the insertion tip and the sensor pass through the hole before entering the person'"'"'s skin.

17. The method of claim 15, wherein the sensor is an analyte monitoring sensor.

18. The method of claim 14, further comprising securing the mount to the person'"'"'s skin.

19. A self arming inserter comprising:

an inserter housing to be received in a mount;

a carrier supported by the inserter housing;

a sensor mounted on the carrier;

a driver which drives the carrier; and

an actuator which actuates the driver;

wherein inserting the inserter housing in the mount arms the driver; and

wherein actuating the actuator releases the driver which drives the carrier, whereby the sensor is inserted into a user'"'"'s skin.

20. A glucose sensor insertion system kit comprising:

a mount;

an inserter housing; and

a glucose sensor which can be carried at least partially into a user'"'"'s skin by a structure in the inserter housing;

wherein mating the mount and the inserter housing arms the glucose sensor insertion system.

21. A method of manufacturing a glucose sensor insertion system comprising:

manufacturing a mount; and

manufacturing an inserter housing which is mateable with the mount and which comprises a structure to carry a glucose sensor at least partially into a user'"'"'s skin, wherein mating the inserter housing and the mount arms the system.
