Abstract

Structures and methods for attaching a device to a user'"'"'s skin are provided. Embodiments include refreshing an adhesive attaching an element of an analyte monitoring device so that a first adhesive attaches the element of the analyte monitoring device during a first time period and a second adhesive attaches the element of the analyte monitoring device to the user'"'"'s skin during a second time period. A sensor remains at least partially inserted into the user'"'"'s while the refreshing of the adhesive from the first to the second adhesive occurs.

Claims

1. A monitoring device element, comprising:

a mount;

a first adhesive on a surface of the housing and adapted to secure the mount to the skin for a first time period; and

a second adhesive on the surface of the housing and adapted to secure the mount to the skin for a second time period.

2. The monitoring device element of claim 1, wherein the first adhesive and the second adhesive are arranged in an alternating pattern.

3. The monitoring device element of claim 2, wherein the alternating pattern comprises alternating stripes.

4. The monitoring device element of claim 1, comprising at least one protrusion attached to the first adhesive;

wherein the first adhesive is removable from the mount by pulling on the at least one protrusion.

5. The monitoring device element of claim 1, comprising a removable covering over the second adhesive;

wherein when the removable covering is removed, the second adhesive is exposed.

6. The monitoring device element of claim 5, further comprising at least one protrusion attached to the removable covering so that the removable covering is removed by pulling on a second protrusion.

7. The monitoring device element of claim 1, wherein at least the second adhesive is movable between a raised position and a lowered position.

8. The monitoring device element of claim 7, wherein the second adhesive is at the raised position during the first time period and at the lower position during the second time period.

9. The monitoring device element of claim 1, further comprising:

a glucose sensor mounted on the mount; and

at least one of a transmitter, receiver or transceiver attached to the mount and coupled to the sensor.

10. A method, comprising:

inserting a sensor at least partially into the skin, the sensor being supported by a sensor housing;

securing the sensor housing to the skin with a first adhesive during a first time period; and

securing the sensor housing to the skin with a second adhesive during a second time period, the second time period being after the first time period;

wherein the sensor remains at least partially inserted into the skin between the first time period and the second time period.

11. The method of claim 10, further comprising removing a covering to expose the second adhesive before securing the sensor housing to the skin with the second adhesive.

12. The method of claim 10, further comprising removing the first adhesive after the first time period.

13. The method of claim 10, further comprising:

between said first time period and said second time period, lifting the sensor housing so that the first adhesive no longer contacts the skin;

removing the first adhesive to expose the second adhesive; and

lowering the sensor housing so that the second adhesive contacts the skin.

14. The method of claim 13, further comprising swiveling the sensor housing before lowering the sensor housing so that the second adhesive contacts the skin at a different location than the first adhesive.

15. A monitoring device element, comprising:

a sensor at least partially inserted into skin;

a sensor housing supporting the sensor, the sensor housing comprising a sensor area and a hinged area;

a hinge hingedly connecting the sensor area and the hinged area; and

a first adhesive and a second adhesive layered on a bottom surface of the hinged area;

wherein the first adhesive is adapted to secure the sensor housing to the skin during a first time period and is removable; and

further

wherein removing the first adhesive exposes the second adhesive, the second adhesive being adapted to secure the sensor housing to the skin during a second time period.

16. The monitoring device element of claim 15, further comprising a partition between the first adhesive and the second adhesive;

wherein the first adhesive is removed and the second adhesive is exposed by removing the partition.

17. The monitoring device element of claim 15, further comprising a third adhesive at a bottom surface of the sensor area, the third adhesive securing the sensor area to the skin.

18. The monitoring device element of claim 15, wherein the hinge allows the hinged area to rotate away from the skin.

19. The monitoring device element of claim 15, wherein the hinge allows the hinged area to swivel around the sensor area in a plane substantially parallel to the skin.

20. A monitoring device element, comprising:

a sensor adapted to be at least partially inserted into skin;

a housing which houses the sensor; and

a first adhesive and a second adhesive provided on a bottom of the sensor housing and being adapted to secure the sensor housing to a user'"'"'s skin;

wherein the first adhesive is stronger than the second adhesive; and

further

wherein the first adhesive and the second adhesive are formed in a pattern so that the first adhesive contacts some areas of the skin and the second adhesive contacts other areas of the skin.

21. The monitoring device element according to claim 20, wherein the pattern comprises concentric circles.

22. The monitoring device element according to claim 20, wherein the pattern comprises alternating stripes.

23. A monitoring device element comprising:

a sensor adapted to be at least partially inserted into skin;

a housing which houses the sensor;

an adhesive provided on a bottom of the sensor housing and being adapted to secure the sensor housing to a user'"'"'s skin;

wherein a thickness of the adhesive varies.

24. A device element comprising:

a sensor mount supporting a sensor;

a plurality of microneedles protruding from the sensor mount and being adapted for insertion into a user'"'"'s skin.
