Abstract
Wound dressings for application to a patient's skin are disclosed, including a dressing layer, a bio-compatible adhesive layer on one side thereof, a support layer on the other side of the dressing layer, the support layer extending around to the other side, and a separate protective layer on the adhesive side of the dressing layer, whereby the extended portion of the support layer is interposed between an edge of the dressing layer and the protective layer so as to facilitate removal and separation of the protective layer from the wound dressing while retaining the dressing layer on the support layer.
Claims53
A wound dressing comprising a dressing layer for application to the skin or mucosa of a host, said dressing layer having a first surface and a second surface, a bio-compatible adhesive layer on said first surface of said dressing layer, a support layer on said second surface of said dressing layer, said support layer including an extending portion extending around to said first surface of said dressing layer, and a separate protective layer on said first surface of said dressing layer, wherein said extending portion of said support layer is interposed between an edge portion of said first surface of said dressing layer and said separate protective layer to thereby facilitate removal and separation of said protective layer from said wound dressing while retaining said dressing layer on said support layer, and wherein said extending portion of said support layer is folded back upon itself to form a gripping portion for removal of said support layer from said dressing layer after said dressing layer has been applied to said skin or mucosa of said host, at least part of said extending portion being interposed between said folded gripping portion and said edge portion of said first surface.
A wound dressing comprising a dressing layer for application to the skin or mucosa of a host, said dressing layer having a first surface, a second surface, a first edge, and a second edge, a bio-compatible adhesive layer on said first surface of said dressing layer, a support layer on said second surface of said dressing layer, said support layer including a first extending portion extending around said first edge to said first surface of said dressing layer and a second extending portion extending around said second edge to said first surface of said dressing layer, and a protective layer on said first surface of said dressing layer, whereby said first and second extending portions of said support layer are interposed between said first and second edge portions of said first surface of said dressing layer and said protective layer to thereby facilitate removal of said protective layer while retaining said dressing layer on said support layer.
A wound dressing comprising a dressing layer for application to the skin or mucosa of a host, said dressing layer having a first surface, a second surface, and a dressing layer fenestration for separating said dressing layer into a first dressing layer portion and a second dressing layer portion and for accommodating a catheter to be applied to said skin or mucosa, a bio-compatible adhesive layer on said first surface of said dressing layer, a support layer on said second surface of said dressing layer, said support layer including an extending portion extending around to said first surface of said dressing layer at a location on said support layer corresponding to said dressing layer fenestration, said support layer including a support layer fenestration corresponding to said dressing layer fenestration, thereby dividing said extending portion of said support layer into a first extending portion and a second extending portion, and a separate protective layer on said first surface of said dressing layer, whereby said first and second extending portions of said support layer are interposed between edge portions of said first surface of said first and second dressing layer portions and said separate protective layer to thereby facilitate removal and separation of said protective layer from said wound dressing while retaining said dressing layer on said support layer, and to further facilitate separate location of said first and second dressing layer portions with respect to said catheter.
