By a pressure-relieving bandage there is arranged a flexible, non-adhesive, waterproof film (2) between a foam layer (1) and a pressure-sensitive adhesive layer (3) containing a hydrocolloid. This will ensure that the expansion of the adhesive by moisture absorption will preferably take place in a direction away from the film (2) and in towards the body. The bandage will therefore not so easily let go of its adhesion to the skin since there is no horizontal displacement of any importance. Moreover, the foam layer is provided with cuts (5) so that large or small sections (6) can be removed from the bandage. The plaster can therefore be used as a pressure-relieving bandage. For prophylactic use it is advantageous to insert a micro-porous tape (7) between the foam layer (1) and the film (2) and to leave out the adhesive layer (3). Instead the underside of the tape (7) and the film (2) is adhesive and protected by a removable protective cover (4).

A bandage for providing pressure relief for portions of a skin area to be covered by the bandage, the bandage including a layer of flexible polymeric foam having an outer peripheral edge and a pressure-sensitive adhesive layer disposed on one side of the foam layer, the adhesive layer having an exposed surface facing in the same direction as said one side of the foam layer for adhering the bandage to a skin area, wherein the improvement comprises: a non-adhesive, waterproof, flexible film arranged on the same side of the foam layer as the adhesive layer, at least part of the foam layer being secured to the film and the film extending to at least the peripheral edge of the foam layer such that the film creates a waterproof barrier on said one side of the foam layer within the area bounded by the peripheral edge of the foam layer.
