초록 ▼

A flexible, transparent wound dressing product contains a clear hydrogel material in a gel-like phase. The wound dressing product is comprised of several layers including a wound dressing, removable tab and release liner. The removable tab provides a grippable surface to allow for the removal of the release liner from the wound dressing and to facilitate handling of the wound dressing during application to the wound site. The tab may be comprised of a flat, double-coated paper or other suitable material, or a flexible, V-shaped member, and is removable by peeling after the wound dressing is applied. The wound dressing comprises a transparent thin-film layer, a first adhesive layer, backing layer, second adhesive layer, support layer and a hydrogel material. The transparent layer has a center portion and a perimeter portion. The backing layer, support layer and hydrogel material, which together form a reinforced hydrogel patch, are positioned in the center portion of the transparent layer. Since the wound dressing is transparent, a grid pattern may be printed on the backing layer to permit measurement of a wound. During manufacture, the hydrogel patch is assembled in sheet form and subsequently cut to a desired size and shape.

대표청구항 ▼

A method of manufacturing a wound dressing product for a wound, comprising the steps of: providing a transparent thin-film layer having a first side and a second side and further having a perimeter portion and a center portion; coating said perimeter portion of said second side of said transparent layer with a first adhesive layer; providing a backing layer having a first side and a second side; coating said second side of said backing layer with a second adhesive layer; providing a support layer having a first side and a second side, said support layer comprising a permeable fabric having a plurality of interstices therewithin; laminating said first side of said support layer to said second side of said backing layer; applying a hydrogel material to said second side of said support layer, wherein said hydrogel material penetrates said interstices to said first side of said support layer such that said hydrogel material resides on both said first side and said second side of said support layer, and whereby said backing layer, said support layer and said hydrogel material collectively form a reinforced hydrogel patch; laminating said hydrogel patch to said center portion of said transparent layer, wherein said first side of said backing layer adheres to said second side of said transparent layer by means of said first adhesive layer; providing a release liner having a first side and a second side; providing at least one removable tab having a first side and a second side, so as to provide a grippable surface to facilitate the removal of said release liner from said transparent layer and to facilitate the handling of said wound dressing during application of said dressing to a wound; laminating said first side of said tab to one edge of said perimeter portion of said second side of said transparent layer, whereby said first adhesive layer is positioned between said tab and said transparent layer; laminating said first side of said release liner to said perimeter portion of said second side of said transparent layer, whereby said adhesive layer is positioned between said transparent layer and said release liner, and said tab portion is positioned between said adhesive layer and said release liner.
