Abstract

A wound dressing and delivery means laminate composite is described comprising contiguously oriented and coplanary arranged discrete layers. A centrally-disposed wound dressing layer is in separable and releasable contiguous adhesive contact through an adhesive surface with an adjacent non-adhesive surface of a release liner layer. A non-adhesive surface of the wound dressing layer is further in separable and releasable contiguous heat lamination contact with an adjacent second non-adhesive surface of a delivery means layer. In using, the release liner layer is first peelably separated from the adhesive surface of the centrally disposed wound dressing layer with which it is in releasable adhesive contact. Next, the remaining adherent wound dressing layer and delivery means layer of the wound dressing composite are positioned over the wound application site and applied to said site by contact adhesion. Finally, the delivery means layer is peelably separated from the adjacently contiguous adhering surface of the wound dressing layer.
