Abstract
A flexible burn dressing product contains a hydrogel material in a gel-like phase. The burn dressing product is comprised of several layers including a burn dressing and a release layer. The burn dressing is comprised of a bacterial barrier layer coated with a bonding layer, a reticulated layer impregnated with a hydrogel material, and a hydrogel material layer. A dimensionally stable backing member may also be adhesively attached to the bacterial barrier layer to help the burn dressing maintain its shape until it is applied to a patient. When the burn dressing product is to be applied to a burn site, the release layer is removed to expose the hydrogel material layer. The remaining layers of the burn dressing product are then applied to the burn site, with the hydrogel material layer directly contacting the burn. Once these layers are in place, the dimensionally stable backing member is removed.
