Reduced-pressure system and method employing a gasket
View Patent ↗A reduced-pressure treatment system for treating a tissue site on a patient includes a gasket releasably attached around a perimeter of the tissue site that may remain in place for an extended time and allows an over-drape to be attached to it. The system and method further may include a manifold sized and configured to be placed in contact with the tissue site; the over-drape positioned over the manifold and sealed to the gasket to create a sealed space between the over-drape and the tissue site; and a reduced-pressure source fluidly coupled to the sealed space to deliver reduced pressure to the tissue site. A method is also presented.
1. A reduced-pressure treatment system for treating a tissue site on a patient, the system comprising:
a gasket releasably attached around a perimeter of the tissue site, wherein the gasket comprises a gasket material, and wherein the gasket has a first side and a second, patient-facing side;
a manifold sized and configured to be placed in contact with the tissue site;
an over-drape positioned over the manifold and releasably sealed to the gasket by a bead of first adhesive between the over-drape and the first side of the gasket, and wherein the gasket is sealed to the patient's epidermis by a second adhesive between the second, patient-facing side of the gasket and the patient's epidermis, to create a sealed space between the over-drape and the tissue site, the over-drape comprising an elastomeric film, and wherein the first adhesive is weaker than the second adhesive; and
a reduced-pressure source fluidly coupled to the sealed space to deliver reduced pressure to the tissue site.
2. The reduced-pressure treatment system of claim 1 , wherein the tissue site is a wound bed and further comprising a gasket tape dispenser for applying the gasket around the perimeter of the tissue site.
3. The reduced-pressure treatment system of claim 1 wherein the gasket material comprises a thin polymer film.
4. The reduced-pressure treatment system of claim 3 wherein the thin polymer film comprises polyurethane.
5. The reduced-pressure treatment system of claim 3 wherein the thin polymer film comprises polyester.
6. The reduced-pressure treatment system of claim 1 wherein the gasket material comprises a hydrocolloid.
7. The reduced-pressure treatment system of claim 1 wherein the gasket is operable to remain releasably attached around the perimeter of the tissue site for one week.
8. The reduced-pressure treatment system of claim 1 wherein the gasket is operable to remain releasably attached around the perimeter of the tissue site for two weeks.
9. The reduced-pressure treatment system of claim 1 , wherein the second adhesive comprises a wet-stick adhesive.
10. The reduced-pressure treatment system of claim 1 , wherein the first adhesive facilitates the removal and reattachment of the over-drape.
