Abstract

An absorbent wound dressing having a layer of hydrophobic silicone gel (3) which is intended to lie against the wound surface when the dressing is worn. A layer of carrier material (2; 7) carries the gel layer and affords the requisite strength thereto. An absorbent body (5) is placed on that side of the carrier material and gel layer which lie distal from the wound surface in use. The carrier material and the gel layer have mutually coinciding penetrating perforations (4) at least within the region of the absorbent body. A fluid barrier layer (6) is provided on that side of the dressing which lies distal from the wound surface in use.
