Abstract
An adhesive wound dressing which comprises a flexible polymer film having an adhesive surface and a non-adhesive surface on the opposite side, a removable protector over the adhesive surface and a detachable handle along an edge margin of the polymer film is described. The handle is used to facilitate handling of the film during application of the dressing and is formed from a tearable material so that it can be removed by tearing without disturbing the applied dressing. In a second described embodiment the tearable handle carries an adhesive coating so that the user has the option of removing the handle or adhering it to the skin of the patient.
