Abstract
A wound dressing for moist wounds is formed from a body layer (1) with a wound-contacting layer (3) attached to an inner surface and a barrier backing layer (2) attached to an outer surface. The body layer (1) is a resiliently compressible moisture-absorbent polyurethane foam film. The wound-contacting layer (3) is preferably a hydrophilic moisture permeable foam film. The barrier backing layer (2) is a liquid and bacteria proof gas-permeable foam
Claims14
A wound dressing comprising a body layer of a resiliently compressible moisture-absorbent foam material, said body layer having an outer surface with a backing layer providing a barrier to liquid applied thereto, and an inner wound-facing surface with a wound-contacting layer applied thereto, said wound-contacting layer comprising an attached layer of a dimensionally stable moisture permeable foam material to control flow of liquid exudate from the wound through said moisture permeable foam material to said moisture-absorbent foam material of said body layer, and said barrier backing layer comprising an attached layer of gas permeable material which has at least a reduced moisture permeability relative to the body layer, said body layer being substantially thicker than said backing and wound-contacting layers.
