Abstract
Systems, kits, methods of manufacturing, and a sealing member for creating a sealed space are described. The sealing member can include a film layer and a first adhesive layer coupled to the film layer. The sealing member can also include a second adhesive layer coupled to the first adhesive layer. A plurality of apertures may extend through the second adhesive layer. Each aperture can expose at least a portion of the first adhesive layer through the second adhesive layer. A plurality of polymer particles may be disposed in the first adhesive layer. The polymer particles can be configured to dissolve in response to interaction with a switching solution.
Claims20
A sealing member, comprising:
- a film layer having a plurality of perforations extending through the film layer;
- a first adhesive layer coupled to the film layer and covering the plurality of perforations, a tackiness of the first adhesive layer configured to decrease in response to application of a solution to the first adhesive layer;
- a second adhesive layer coupled to the first adhesive layer;
- and
- 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.
A kit for forming a seal over a portion of a patient's body, the kit comprising:
- a drape comprising:
- an outer layer having a first side, a second side, and a plurality of perforations extending through the outer layer,
- a first adhesive covering the plurality of perforations on the second side of the outer layer,
- a second adhesive coupled to the first adhesive and having a plurality of apertures extending through the second adhesive, each aperture exposing at least a portion of the first adhesive through the second adhesive,
- a first release member releasably coupled to the first side of the outer layer, and
- a second release member releasably coupled to the second adhesive;
- and
- a solution configured to decrease an adhesive strength of the first adhesive if applied to the first side of the outer layer.
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;
- a sealing adhesive coupled to the high-strength adhesive and having a plurality of apertures extending through the sealing adhesive, each aperture exposing at least a portion of the high-strength adhesive through the sealing adhesive;
- and
- a switching solution, wherein when the switching solution is applied to the high-strength adhesive, the tackiness of the high-strength adhesive decreases.
