An adhesive dressing suitable for moist wounds includes a first layer comprising a substrate having a layer of pressure sensitive adhesive on a wound facing surface and a second layer comprising a moisture vapour permeable continuous film. The second layer is attached to the non wound facing surface of the first layer at spaced apart intervals thereby to form a plurality of discrete cellular voids between said first and second layers. The first layer has apertures therein to allow passage of liquids therethrough into the cellular voids and total area of the dressing defined by the cellular voids is from 20 % to 80 % of the total operable area of the dressing.

Un pansement adhésif approprié aux blessures humides comprend une première couche constituée d'un substrat possédant une couche d'adhésif qui adhère par pression sur une surface faisant face à la blessure et une seconde couche constituée d'un film continu, perméable à la vapeur. La seconde couche est fixée à la surface, ne faisant pas face à la blessure, de la première couche, à intervalles espacés, afin de former une pluralité de vides cellulaires séparés entre cette première et seconde couches. La première couche possède des orifices afin de faciliter le passage des liquides dans les vides cellulaires et la surface totale du pansement définie par les vides cellulaires représente de 20 % à 80 % de la surface totale utilisable du pansement.
