Abstract

A conformable dressing such as a first-aid dressing or a ward dressing comprises a polymeric foam absorbent layer (2) having a liquid impervious moisture vapour permeable backing layer (3) and on the body facing surface, a discontinuous layer of adhesive (4), there being at least one region (7) of the body facing surface of said absorbent layer that is free from adhesive. The adhesive may be applied directly to the foam or may be applied to an intermediate discontinuous layer such as a polymer net (5) which itself is laminated or bonded to the foam absorbent layer.
