Abstract
Abstract A catheter attachment device comprises a first pad of medical grade adhesive having one surface covered by a removable protective layer, a second surface covered by a plastics film, and, attached to the film, a second pad of medical grade adhesive. A surface of this second pad which faces away from the first pad is covered by a removable protective layer and has a plastics film on its other surface. The two plastics films are attached to each other over a central region substantially smaller in area than the areas of both the first and second pads.
