  • Patent number: 5074293
    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. Strips 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.

  • Patent number: 5052381
    Abstract: A simple construction of a two-component adhesive film, external wound dressing, comprises a backing sheet of thin, preferably elastomeric and water vapor-permeable film protected by a release layer comprising two release sheets. The sheets not only protect the adhesive coating on the front face of the film, but also are instrumental in allowing the film to be precisely positioned over a wound, then gradually tensioned with a force no greater than the peel strength for the release sheets, while the dressing is applied. This feature of the dressing allows it to be smoothly applied over the wound with a predetermined amount of force while conforming the film to the contours of an injured body. This features is the result of providing each first and second release sheets with a relatively wide margin, at least 1.25 cm (0.5 inch) wide. The peel strength for each release sheet is essentially identical.

The action of pulling the strip away from the spool over the platform causes a portion of the protective covering of strip to be sliced by the slicer. This will expose a bandage which then can be lifted off the remaining portion of the protective coating for use. After this, the cutter is used to separate the bandageless strip from the device for subsequent disposal.

  • Patent number: 4915102
    Abstract: Devices for applying film layers and/or active agent carriers to the skin are disclosed, including a liner layer having a release surface, a carrier layer for the film layer, a first adhesive between the carrier layer and the film layer, and a second adhesive between the liner layer and the opposite surface of the film layer and carrier layer. In this manner, the film layer is sandwiched between the liner layer and carrier layer, and the coefficients of adhesion of the two adhesives are selected so that upon separation of the liner layer and the carrier layer the film layer remains on the carrier layer, and upon application of the film layer to the skin, the film layer transfers from the carrier layer to the skin. The device preferably includes a hinge permanently connecting a peripheral edge of the carrier layer to the liner layer in order to facilitate this process, and in a preferred embodiment an active agent carrier is either substituted for or added to the film layer.

  • Patent number: 4884563
    Abstract: A non-stretchable wound dressing has a flexible, non-stretching cover sheet having adhesive on one side thereof, and having two spaced strip-form gripping tabs at opposite ends thereof. The cover sheet covers a urethane wound dressing with the adhesive of the cover sheet being in contact with the urethane, and the urethane having an adhesive layer on an opposite side thereof. For storage and prior to application to a patient, the adhesive of the urethane wound dressing is in contact with a releasable surface of a carrier, such as a cardboard. For application to a patient, one of the cover sheet gripping tabs is pulled so as to release the cover sheet and wound dressing from the carrier, the cover sheet preventing stretching of the wound dressing. The combination is then applied to a patient, with the adhesive of the wound dressing in contact therewith, again the cover sheet preventing stretching of the wound dressing.
