ADHESIVE WOUND DRESSING

摘要

Moisture vapour transmitting wound dressings are described which comprise (a) a conformable backing layer which has an adhesive on one of its surfaces and in which at least one of the backing layer and adhesive layer is continuous so as to provide a barrier both to bacteria and to liquid water when the dressing is in place on a wound and (b) a low wound adherency absorbent pad positioned on the adhesive side of the backing layer. The area of the pad is less than that of the backing layer so that an adhesive margin remains exposed on two, or preferably four, sides of the pad so that the backing layer may be adhered to the skin surrounding the wound area. The wound dressings have a moisture vapour transmission rate of from 500 to 2000 grams/square metre/24 hours at 37.5 DEG C and 100% to 10% relative humidity difference. Materials for use in the dressings and processes for manufacture of the dressings are also described.
