The present invention relates to a closed dressing material that provides a wet environment by directly contacting a wound as a wound dressing. The present invention provides a microporous polyurethane film wound surface contact layer (10) having a thickness of 10 to 200 µm with microcellular granules (12) having an average diameter of 1 to 20 µm and macropores (14 to 200 µm), and the wound Provided is a closed dressing dressing for a wound coating comprising a base layer 20 and / or a fibrous absorbent layer 30 bonded to the top of the surface contact layer 10. In addition, a closed dressing material having a structure in which a moisture-permeable outer protective film layer 40 is bonded to the base layer 20 or the fibrous absorbent layer 30 is provided. Accordingly, the present invention has excellent effluent absorption ability and non-wound surface adhesion characteristics from its structural features, promotes wound healing by preventing invasion of bacteria, bacteria, foreign substances, etc. from the outside and providing an appropriate wet environment to the wound. |
