Disclosed is a wound dressing consisting of a primary dressing for placement on the skin to cover a wound and an overlying secondary dressing containing an absorbent pad for receiving and retaining wound fluids diffusing thereto from the underlying wound and primary dressing, the secondary dressing being releasably secured to the primary dressing around their common periphery by a pressure-sensitive adhesive, at least the peripheral outer surface of the primary dressing having a release coating whereby to facilitate removal and replacement of the secondary dressing without disturbing the primary dressing or the healing wound therebeneath.
In a composite vented wound dressing comprising: (a) a primary dressing for placement over a wound, the primary dressing having a thin, conformable sheet material having a pressure-sensitive adhesive coating on one surface thereof for adhering the dressing to the skin and vent means for diffusing wo
In a composite vented wound dressing comprising: (a) a primary dressing for placement over a wound, the primary dressing having a thin, conformable sheet material having a pressure-sensitive adhesive coating on one surface thereof for adhering the dressing to the skin and vent means for diffusing wound fluid through the sheet material; and (b) a secondary dressing in superposition with non-adhesive-bearing surface of the sheet material of the primary dressing, the secondary dressing having a reservoir for receiving and retaining wound fluid diffusing thereto through the vent means in the primary dressing therebeneath and a cove sheet covering the reservoir, the cover sheet having a layer of pressure-sensitive adhesive at least around the periphery of the surface in juxtaposition with the superposed sheet material of the primary dressing to releasably seal the secondary dressing to the surface of the primary dressing, the secondary dressing thereby being removable and replaceable as needed without disturbing the primary dressing covering the wound; the improvement wherein the non-adhesive-bearing surface of the sheet material of the primary reference in contact with the pressure-sensitive adhesive coating on the cover of the secondary dressing to releasably secure the respective dressings together contains a release coating to facilitate removal of the secondary dressing, the release coating being adapted to retain the dressings together so a to prevent accidental or unwanted separation while at the same time permitting ready separation of the secondary dressing from the primary dressing.
