Abstract

Embodiments of the present invention provide a device and method for treating animal skin to produce tautness in the skin during the insertion of an analyte sensor. A device in accordance with embodiments of the present invention includes a housing that partially encloses a cavity and is adapted for mounting onto animal skin and a sensor insertion module adapted to insert an analyte sensor through animal skin.

Claims

1. A skin tautening device, comprising:

a housing configured for mounting onto animal skin, the housing having an outer surface, a proximal end, and a distal end, and one or more elastomeric components, wherein placement of the housing against the animal skin and application of force to the housing exerts lateral force on the animal skin to tauten the animal skin; and

a sensor insertion module coupled to the housing and projecting at least partly through the housing, wherein the sensor insertion module is adapted to insert an analyte sensor into animal tissue.

2. The skin tautening device of claim 1, further comprising a breaching aid coupled to or provided by the sensor insertion module.

3. The skin tautening device of claim 2, wherein the breaching aid comprises a stylet.

4. The skin tautening device of claim 2, wherein the breaching aid comprises a trocar.

5. The skin tautening device of claim 2, wherein the breaching aid comprises a liquid adapted for delivery under high-pressure.

6. The skin tautening device of claim 2, wherein the breaching aid comprises a gas adapted for delivery under high-pressure.

7. The skin tautening device of claim 1, further comprising an auto-inserter coupled to the sensor insertion module.

8. The skin tautening device of claim 7, wherein the auto-inserter includes a high-speed motive force device.

9. The skin-tautening device of claim 8, wherein the high-speed motive force device comprises a solenoid.

10. The skin tautening device of claim 8, wherein the high-speed motive force device comprises a spring.

11. The skin tautening device of claim 8, wherein the high-speed motive force device comprises a compressed gas cartridge.

12. The skin tautening device of claim 8, wherein the high-speed motive force device comprises an air pump.

13. The skin tautening device of claim 8, wherein the high-speed motive force device comprises an electromagnetic accelerator.

14. The skin tautening device of claim 1, further comprising a guidance structure coupled to the sensor insertion module for providing axial support to a sensor.

15. The skin tautening device of claim 1, further comprising a stimulus-sensitive actuator configured to facilitate movement of a sensor when actuated.

16. The skin tautening device of claim 15, further comprising a guidance structure coupled to the sensor insertion module for providing axial support to a sensor, wherein the stimulus-sensitive actuator is located on the guidance structure.

17. The skin tautening device of claim 15, wherein the stimulus-sensitive actuator comprises an actuator sensitive and responsive to at least one of pressure, one or more chemicals, heat, light, pH, moisture, or electrical conductivity.
