Abstract
An improved wound dressing composite is disclosed, having a membrane film wound dressing, a relatively stiff substantially planar carrier sheet with tabs, and a releasable cover. The film dressing has an upper surface, a lower adhesive surface and opposed side edges for application in a spread out disposition to a wound site with the lower surface adhered thereto. The film dressing, being relatively thin, is substantially unable to support itself in a planar configuration. The carrier sheet has an upper surface, a lower surface, and opposed edges. The carrier sheet is releasably adhered on its lower surface to the upper surface of the film dressing in supporting relation for supporting the film dressing in a planar configuration, with the side edges of the film dressing and carrier sheet generally aligned in close adjacency. At least one tab is attached to the carrier sheet adjacent at least one of the side edges thereof, and extends out beyond the side edge of the carrier sheet and the adjacent side edge of the film dressing. The tab is used to remove the carrier sheet from the film dressing after application. A cover protects the lower adhesive surface of the film dressing prior …
