First Claim
Patent Images
1. A sealing system for use in treating a tissue site on a patient with reduced pressure, the sealing system comprising:
- an outer layer formed from a drape material and having a first side and a second side, wherein the outer layer is formed with a plurality of slits extending through the outer layer and having no drape material removed from the outer layer;
a high-strength adhesive coupled to the second side of the outer layer, wherein the high-strength adhesive has a first side, a second side, and a tackiness; and
a switching solution, wherein when the switching solution is applied to the high-strength adhesive, the tackiness of the high-strength adhesive decreases.

Abstract
A sealing system that includes a switchable drape is presented. The drape provides enhanced sealing by using a high-strength adhesive. In one instance, the switchable drape has a plurality of perforations through which a switching solution may be delivered to the high-strength adhesive. The switching solution causes the high-strength adhesive to become less adhesive so that the switchable drape may be removed more easily. Other systems, methods, and drapes are presented.

15. A kit for forming a seal over a portion of a patient'"'"'s body, the kit comprising:
-
a switchable drape; a switching solution; wherein the switchable drape comprises; an outer layer formed from a drape material and having a first side and a second side, wherein the outer layer is formed with a plurality of perforations extending through the outer layer, a high-strength adhesive coupled to the second side of the outer layer, wherein the high-strength adhesive has a first side and a second side, a first release member releasably coupled to the first side of the outer layer, and a second release member releasably coupled to the second side of the high-strength adhesive; and wherein, once applied, the switching solution lessens the adhesive strength of the high-strength adhesive.
