Sealing systems and methods employing a hybrid switchable drape

A system for providing negative-pressure therapy, the system comprising:

• a tissue interface configured to be disposed proximate to a tissue site;
• a cover configured to be disposed over the tissue interface to form a sealed space containing the tissue interface, the cover comprising:
• a barrier layer;
• an acrylic adhesive layer coupled to the barrier layer;
• a silicone gel layer coupled to the acrylic adhesive layer;
• a plurality of apertures extending through the silicone gel layer, exposing at least a portion of the acrylic adhesive layer through the silicone gel layer;
• and
• a plurality of release agents disposed in the acrylic adhesive layer, the release agents configured to dissolve in response to interaction with a release solution;
• and
• a negative-pressure source configured to be fluidly coupled to the sealed space to draw fluid from the sealed space.

A method for removing a drape, the method comprising:

• applying a switching solution to a drape, wherein the drape comprises:
• a film layer;
• a first adhesive layer coupled to the film layer;
• a second adhesive layer coupled to the first adhesive layer;
• a plurality of apertures extending through the second adhesive layer, each aperture exposing at least a portion of the first adhesive layer through the second adhesive layer;
• and
• a plurality of polymer particles disposed in the first adhesive layer;
• dissolving the polymer particles with the switching solution to reduce a bond strength of the first adhesive layer;
• and
• lifting an edge of the drape.
