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 for releasably attaching proximate the tissue site;
a manifold sized and configured to be placed in contact with the tissue site;
an over-drape placed over the manifold and sealed to the gasket to provide a sealed space between the over-drape and the tissue site;
a reduced-pressure source operable to deliver reduced pressure to a sealed space; and
a delivery conduit for fluidly coupling the reduced-pressure-source to the manifold;
wherein the over-drape is sealed to the gasket by a bead of a first attachment apparatus between the over-drape and a first side of the gasket;
wherein a second attachment apparatus is disposed on a second side of the gasket adapted for attachment proximate the tissue site; and
wherein the first attachment apparatus is weaker than the second attachment apparatus.
2. The reduced-pressure treatment system of claim 1 wherein the first attachment apparatus is a first adhesive and the second attachment apparatus is a second adhesive.
3. The reduced-pressure treatment system of claim 1 wherein the gasket 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 comprises a hydrocolloid.
7. The reduced-pressure treatment system of claim 1 wherein the gasket is operable to remain releasably attached proximate the tissue site for one week.
8. The reduced-pressure treatment system of claim 1 wherein the gasket is operable to remain releasably attached proximate the tissue site for two weeks.
9. A reduced-pressure treatment system,
comprising:
a manifold;
a gasket comprising a first side and a second side;
an over-drape placed over the manifold and attached to the first side of the gasket; and
a reduced-pressure source coupled to the manifold and operable to deliver reduced pressure to the manifold;
wherein the over-drape is sealed to the gasket by a bead of a first attachment apparatus;
wherein a second attachment apparatus is disposed on the second side of the gasket and adapted to be attached to a periwound area of an epidermis; and
wherein the first attachment apparatus is weaker than the second attachment apparatus.
10. The reduced-pressure treatment system of claim 9 , wherein the first attachment apparatus is a first adhesive and the second attachment apparatus is a second adhesive.
11. The reduced-pressure treatment system of claim 9 , wherein the gasket is a gasket tape.
12. The reduced-pressure treatment system of claim 9 , wherein the manifold comprises a reticulated open-cell foam.
