DRESSING SYSTEM FOR USE ON DEEP WOUNDS WITH REDUCED IN-GROWTH AND EXTENDED WEAR TIME

摘要

A dressing may include a perforated film, a manifold, and a cover. The perforated film may include a polymer and a plasticizer. The film may be configured to extend over a wound and a periwound of the tissue site, and may be highly flexible and conformable to a deep wound. The film layer may be plastically deformed when pushed into the wound. The film may be breathable and non-adherent to granulation. The manifold may be configured to be adjacent to the film and may backfill the wound. The cover may be disposed over the manifold and coupled to the film around the manifold. In some embodiments, a dressing may include a polymer film layer including a plurality of sacrificial sections configured to break open when the film layer is pushed into the wound. The openings may allow the manifolding of fluid while reducing or inhibiting ingrowth of tissue into the manifold.
