Abstract
A dressing for treating a tissue site with negative pressure may comprise a cover having an adhesive, a manifold, a perforated polymer film, and a perforated silicone gel having a treatment aperture. The cover, the manifold, the perforated polymer film, and the perforated silicone gel may be assembled in a stacked relationship with the cover and the perforated silicone gel enclosing the manifold. The perforated polymer film may be at least partially exposed through the treatment aperture, and at least some of the adhesive may be exposed through the perforated silicone around the treatment aperture.
Claims20
A dressing for treating a tissue site with negative pressure, the dressing comprising:
- a first layer comprising a manifold;
- a second layer comprising a film and a plurality of fluid restrictions adjacent to the manifold;
- and
- a third layer comprising a coating adjacent to the second layer, wherein a treatment aperture and a plurality of perforations around the treatment aperture are disposed through the coating, and wherein at least a portion of the plurality of fluid restrictions are exposed through the treatment aperture.
A dressing for treating a tissue site with negative pressure, the dressing comprising:
- a foam manifold configured to fluidly communicate negative pressure and wound fluid;
- a lower surface having an open area configured as a passage for the negative pressure and the wound fluid;
- a drape area surrounding the open area, the drape area configured to seal to tissue and not including openings for the passage of the negative pressure or the wound fluid;
- and
- a polymer film wound contact layer extending across the open area in the lower surface and having openings for the passage of the negative pressure and the wound fluid into the foam manifold.
A dressing for treating a tissue site with negative pressure, the dressing comprising:
- a sealing layer comprising a treatment aperture and a plurality of perforations around the treatment aperture;
- a fluid control layer comprising a plurality of fluid restrictions aligned with the treatment aperture;
- and
- a manifold adjacent to the fluid restrictions.
