Abstract
The present invention is an apparatus and system of isolating a fistula (e.g., an enteric fistula or an ostomy stoma) from within a wound bed, for use in conjunction with a negative pressure, suction-based dressing system comprised of an isolation component and a porous dressing component with an aperture that corresponds to the size and shape of the isolation component. The isolation component further includes an opening which is centered surrounding a fistula, exposing the fistula. The inner wall of the isolation component is air and fluid impermeable. The isolation component is secured to the wound tissue surrounding the fistula with adhesive while a negative pressure dressing system surrounds the isolation component.
Claims20
An apparatus for isolating a fistula from contiguous moist wound tissue area comprised of:
- a porous dressing component having at least one aperture, said aperture adapted to provide access to said fistula, said aperture being further adapted to receive an isolation component, said isolation component having an impermeable inner surface, an outer surface, a top perimeter edge and a bottom perimeter edge.
A modular system for constructing an apparatus for isolating a fistula from contiguous moist wound tissue area comprised of:
- at least one porous dressing component constructed of a material which may be cut to the desired dimensions and which has an aperture in the desired location which corresponds to the size of an isolation component, said aperture adapted to receive and secure an isolation component;
- and
- a plurality of isolation components, each having a pre-configured size and a pre-configured aperture.
An apparatus for isolating enteric contents from a fistula comprised of:
- a ring-shaped structure having an outer surface and an impermeable inner surface adapted to enclose said fistula and prevent said enteric contents from communicating with a porous dressing.
