Abstract

A wound dressing for use with exuding wounds is provided comprising a porous hydrophobic layer adapted to directly contact the wound during use and an adjacent absorbent layer attached to said hydrophobic layer, said hydrophobic layer comprised of an elastic net-like porous reinforcing component substantially completely encapsulated by a soft and elastic hydrophobic gel while retaining the porosity of said reinforcing component, said hydrophobic layer thus including openings which permit wound exudate to pass through said hydrophobic layer to be absorbed by said outer absorbent layer.
