ABSTRACT:
A flexible 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, optional removable tab and optional release liner. The wound dressing comprises a thin-film layer, an adhesive layer, porous backing layer, optional support layer and a hydrogel material. The thin-film 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 thin-film layer. The porous backing layer is formed of a porous material having sufficient porosity that the backing layer can be secured to the hydrogel material without the use of an adhesive. During manufacture, the hydrogel patch is assembled in sheet form and subsequently cut to a desired size and shape.
