Releasable medical drapes
A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.
1. A releasable medical drape comprising:
a film;
a mesh coupled to the film;
a plurality of strands coupled to at least one of the mesh and the film;
a pressure-sensitive adhesive coating the mesh; and
a soft-gel coating the plurality of strands.
2. The releasable medical drape of claim 1 , wherein the film is flexible.
3. The releasable medical drape of claim 1 , wherein the film is liquid-impermeable.
4. The releasable medical drape of claim 1 , wherein the film is vapor-permeable.
5. The releasable medical drape of claim 1 , wherein the film has a thickness between about 15 microns and about 50 microns.
6. The releasable medical drape of claim 1 , wherein the pressure-sensitive adhesive has a coating weight between about 15 grams/m2 to about 70 grams/m2.
7. The releasable medical drape of claim 1 , wherein the soft-gel has a coating weight between about 30 grams/m2 and about 70 grams/m2.
8. The releasable medical drape of claim 1 , wherein the soft-gel has a stiffness between about 5 Shore OO and about 80 Shore OO.
9. The releasable medical drape of claim 1 , wherein the mesh comprises a plurality of interlocked strands.
10. The releasable medical drape of claim 1 , wherein the mesh and the plurality of strands are misregistered.
11. A system for treating a tissue site comprising:
a manifold configured to be disposed over the tissue site;
a reduced-pressure source configured to be fluidly coupled to the manifold to supply negative pressure to the tissue site; and
a releasable medical drape comprising:
a film;
a mesh coupled to the film;
a plurality of strands coupled to at least one of the mesh and the film;
a pressure sensitive adhesive coating the mesh; and
a soft-gel coating the plurality of strands.
12. The system of claim 11 , wherein the film is flexible.
13. The system of claim 11 , wherein the film is liquid-impermeable.
14. The system of claim 11 , wherein the film is vapor-permeable.
15. The system of claim 11 , wherein the film has a thickness between about 15 microns and about 50 microns.
16. The system of claim 11 , wherein the pressure-sensitive adhesive has a coating weight between about 15 grams/m2 to about 70 grams/m2.
17. The system of claim 11 , wherein the soft-gel has a coating weight between about 30 grams/m2 and about 70 grams/m2.
18. The system of claim 11 , wherein the soft-gel has a stiffness between about 5 Shore OO and about 80 Shore OO.
19. The system of claim 11 , wherein the mesh comprises a plurality of interlocked strands.
20. The system of claim 11 , wherein the mesh and the plurality of strands are misregistered.
