Abstract
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.
Claims20
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.

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.
A system adapted for assembly to treat tissue, comprising:
- a manifold adapted for placement proximate to the tissue;
- a gasket adapted for placement on a periwound area around the tissue;
- an over-drape adapted to cover the manifold member and to extend past a peripheral edge of the manifold member to form a drape extension;
- a first attachment apparatus adapted for application between the drape extension and the gasket;
- and
- a second attachment apparatus adapted for application between the gasket and the periwound area;
- wherein the first attachment apparatus is weaker than the second attachment apparatus.
