Abstract

A device includes an outer layer formed of a fluid impermeable polymer film. The outer layer forms an outer major surface of the device. The device also includes a reinforcement layer underlying the outer layer and an adhesive underlying the outer layer. The adhesive forms an annular adhesive surface wherein the device is configured to form a cavity between an inner surface of the device and a dermal surface when the annular adhesive surface is attached to the dermal surface. The device further includes a fluid conduit operable to provide fluid access to the cavity through the outer layer and the reinforcement layer.

Claims

1. A device comprising:

an outer layer formed of a fluid impermeable polymer film, the outer layer forming an outer major surface of the device;

a reinforcement layer underlying the outer layer;

an adhesive underlying the outer layer, the adhesive forming an annular adhesive surface, wherein the device is configured to form a cavity between an inner surface of the device and a dermal surface when the annular adhesive surface is attached to the dermal surface; and

a fluid conduit operable to provide fluid access to the cavity through the outer layer and the reinforcement layer.

2. The device of claim 1, wherein the outer layer extends beyond the outer contour of the reinforcement layer.

3. The device of claim 1, wherein the outer layer includes an olefinic elastomer.

7. The device of claim 1, wherein the reinforcement layer includes vinyl polymer.

8. The device of claim 1, wherein the reinforcement layer includes a polyolefin.

9. The device of claim 1, wherein the reinforcement layer includes a woven fiber.

10. The device of claim 1, wherein the outer layer has a thickness not greater than a thickness of the reinforcement layer.

16. The device of claim 1, wherein the reinforcement layer has an elastic modulus of at least about 400 ksi.

18. The device of claim 1, wherein the outer layer has an elongation of at least about 80%.

20. The device of claim 1, wherein the reinforcement layer has an elongation not greater than about 200%.

23. The device of claim 1, further comprising a liner underlying the reinforcement layer.

24. The device of claim 23, wherein the liner extends beyond the outer contour of the reinforcement layer and wherein the outer layer extends beyond the outer contour of the liner.

25. The device of claim 23, wherein the liner includes an adhesive surface in contact with the reinforcement layer.

27. The device of claim 1, wherein the adhesive is included on a major surface of the outer layer opposite the outer major surface.

30. The device of claim 1, further comprising a sensor operably coupled to the cavity.
