Abstract

A two-stage wound dressing assembly includes a wound cover and a carrier. The wound cover has a length and width substantially greater than a height (or thickness), a first major surface, and a second major surface comprising a polyurethane film, opposite the first. The first major surface has disposed thereon a wound cover pressure sensitive adhesive comprising a colloidal absorbent, and it is arranged and configured to adhere to mammalian skin during use. The carrier has a length and width substantially greater than a height (or thickness), a first major surface, and a second major surface, opposite the first. The carrier is formed of a foamed polymeric web having a height of between about 200 and about 500 μm. The first major surface of the carrier is disposed in facing relation and is removably attached to the second major surface of the wound cover, and it has disposed thereon at least one pressure sensitive adhesive. After application of the wound cover to skin for use, the carrier is removable from the wound cover to leave the wound cover adhered to the skin.
