Abstract
A dressing for treating a tissue site is provided herein which may comprise a cover, an adhesive layer coupled to the cover and a tissue interface coupled to the adhesive layer. The dressing may be used to treat the tissue site with negative pressure. The adhesive layer may contain microcapsules containing an adhesive capable of being released upon heat, movement, force and/or sheer to reduce or prevent leakage from the dressing. The microcapsules may be dispersed in the adhesive layer and/or present on the surface of the adhesive layer. Compositions and methods of use are also provided herein.
Claims13
A dressing comprising:
- a cover having a first side and a second side;
- an adhesive layer comprising a first adhesive coupled to at least part of the first side of the cover;
- wherein microcapsules comprising a second adhesive encapsulated by a polymer are embedded in or present on a surface of the adhesive layer;
- and
- a tissue interface coupled to the adhesive layer.
A method of treating a tissue site with negative pressure, the method comprising:
- applying a dressing to a tissue site, the dressing comprising:
- a cover having a first side and a second side;
- an adhesive layer comprising a first adhesive coupled to at least part of the first side of the cover;
- wherein microcapsules comprising a second adhesive encapsulated by a polymer are embedded in or present on a surface of the adhesive layer;
- and
- a tissue interface coupled to the adhesive layer;
- sealing the dressing to epidermis adjacent to the tissue site;
- fluidly coupling the dressing to a negative-pressure source;
- and
- applying negative pressure from the negative-pressure source to the dressing.
