Patent ID: 8920830

Claim:
A cold adapted wound dressing device ( 10 ) designed to promote healing of a wound to which it is applied, the dressing device ( 10 ) consisting essentially of: a wound covering ( 12 ) having a wound contacting layer ( 16 ) with a wound contacting surface ( 20 ); a wound treatment material ( 40 ), wherein the wound contacting layer ( 16 ) consists essentially of the wound treatment material ( 40 ); and a heat absorbing layer ( 50 ) in heat flow communication with the wound contacting layer ( 16 ), the heat absorbing layer ( 50 ) adaptable to remove heat from the wound contacting layer ( 16 ) and reducing a temperature of the wound contacting surface ( 20 ) to below an ambient temperature, to provide the cold adapted wound dressing device ( 10 ) for promoting healing of the wound, wherein the wound contacting layer ( 16 ) is a porous matrix ( 30 ) that allows aqueous fluids to freely diffuse into and through the matrix, the matrix comprising a fibrous material ( 32 ) which is impregnated with the wound treatment material ( 40 ), wherein the wound treatment material ( 40 ) consists essentially of a natural Hyaluronic Acid and/or Chitosan and/or Diacerhein, and wherein the heat absorbing layer ( 50 ) comprises a hydrated super absorbent polymer ( 70 ) that is hydrated to not more than 20 percent of the polymer's capacity.
