ABSTRACT:
A wound dressing comprises a vapor permeable plastic film coated on one side with an adhesive about the periphery of a wound contacting window in the central portion of the dressing. A pair of release liners covers the adhesive coating and include tabs so that the release liners can be peeled from the adhesive coating. Means are provided adjacent to and at opposite lateral sides of the wound contacting window to change abruptly the resistance to peeling of the release liners from the adhesive coated film. Accordingly, when the user feels this change in resistance, he or she knows that the wound contacting window and a small portion of the adhesive about the periphery thereof is uncovered which allows the dressing to be anchored about the patient's wound with the release liners partially in place and the wound contacting window exposed. This minimizes the tendency of the film to wrinkle and/or to fold on itself such that the adhesive adheres to itself.
