摘要: A wound dressing having a porous layer with a good affinity to tissue of organisms comprising (a) a first layer to be placed on the wound surface having pores of 20 to 500 .mu.m in diameter, and 1 to 10 mm thick, and (b) a second layer remote from the wound surface having pores not more than 20 .mu.m in diameter, and 0.5 to 5 .mu.m thick. The first layer can be provided with an antimicrobial of not more than 50% by weight, and the second layer can contain an antimicrobial of 10 to 80% by weight.
