Abstract
Abstract A thin adhesive coated film dressing is provided with the adhesive surface covered by a release paper in three sections to facilitate the application of the dressing to the wound site. The construction of the dressing provides for the center section of the release paper to be removed to expose the central adhesive area of the film. While gripping the film by the two end portions still covered by the release paper, the central portion of the dressing is applied to the wound site. Once the center section is secure, the end sections of the release papers are removed and application of the dressing completed.
