Estimating the term…
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.
An adhesive dressing comprising a first comprising a substrate having a layer of adhesive on a wound facing surface and a second layer comprising a moisture vapour permeable continuous film, said second layer being 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, wherein each cellular void is surrounded by a peripheral seal area, which seal area prevents liquid from directly entering an adjacent cellular void, wherein the first layer has apertures therein to allow the passage of liquids therethrough into the cellular voids and wherein the total area defined by the cellular voids is from 20 to 80% of the total operable area of the dressing.
