Abstract
This utility model relates to a composite dressing, comprising: an adhesive layer, mainly made of a hydrocolloid material, including an absorbent area with multiple drainage holes for covering the wound and a sealing area for covering the skin surrounding the wound; an absorbent layer, mainly made of a superabsorbent material, disposed on the side of the adhesive layer facing away from the wound to cover the absorbent area of the adhesive layer, wherein the superabsorbent material absorbs at least ten times its own weight in wound exudate; and a backing layer, disposed to cover the absorbent layer and connected to the sealing area of the adhesive layer on the side facing away from the wound. This composite dressing overcomes the shortcomings of existing single-type dressings that struggle to simultaneously achieve high absorbency and maintain a moist environment, effectively managing wound exudate and maintaining a moist healing environment.
