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, a release layer, and a dimensionally stable backing member. The wound dressing is comprised of a thin-film transparent layer having an adhesive perimeter portion and a center portion, and a hydrogel material positioned in the center portion of the transparent layer. Since the wound dressing is transparent, a grid pattern may be printed on the thin-film transparent layer to permit measurement of a wound. During manufacture, a vacuum pressure is applied to allow temporary access to the center portion of the thin-film transparent layer, creating a cavity for insertion of the hydrogel material. The dimensionally stable backing member is then adhesively attached around the perimeter portion of the thin-film transparent layer to help the wound dressing maintain its shape. When the wound dressing product is to be applied to a wound site, the release layer is removed, preferably using an extending tab attached thereto, to expose the hydrogen material. The remaining layers of the wound dressing product are then applied to the wound site, with the hydrogel material directly contacting the wound. Once these layers are in place, the dimensionally stable backing member is removed, preferably using an extending tab attached thereto.
