WOUND DRESSING

摘要

Disclosed is a wound dressing protecting wounds through direct contact with wounds. The dressing includes a wound contacting layer that is made of a microporous polyurethane film, contains a plurality of micropores with an average diameter of 5-80 gm and a means for absorbing highly viscous wound exudates, and is 10-200 µm thick, and a supporting layer that is combined with an upper surface of the wound contacting layer. The supporting layer is composed of a base sheet layer and/or a fibrous absorbent sheet layer with high absorptivity. The means for absorbing highly viscous wound exudates is a plurality of macropores 100­ 1,000 µm in diameter and/or slits 0.1-10 mm long. The dressing preferably further includes an outer protective film layer that is combined with an upper surface of the supporting layer. Due to its structural properties, the dressing has excellent non-adherence to wounds and high absorptivity to exudates, prevents the infiltration of external bacteria and impurities and provides a suitably moist environment to wounds, thereby promoting wound healing.
