摘要： The present invention provides a wound dressing in the form of a gauze or similar absorbent material having a partially or substantially dehydrated hydrogel material impregnated therein for absorbing wound exudate. The wound dressing is capable of absorbing large amounts of wound exudate without inhibiting the healing of the wound to which it is contacted and without the need for additional backing or adhesive layers. The wound dressing also has a pliable, soft structure which permits the dressing to be applied to wounds having irregular shapes and depths.

摘要： An elongated, self-adhesive wound dressing is provided which includes a hydrogel layer secured to a vapor permeable bacterial barrier layer. The vapor permeable barrier layer possesses sufficient porosity such that it readily adheres to the hydrogel layer without the need for an adhesive layer. The wound dressing is adapted to be wrapped around a portion of a patient's body and secured without the use of an adhesive.

摘要： A sterile wound packing material and package therefor is provided, which wound packing is flexible and conformable to deep and/or irregular shaped wounds, is compact and easily dispensed, and which can be stored indefinitely. The wound packing may also be used for absorbing wound exudate and immediately discarded or may be designed to remain in place for extended periods during healing. The wound packing includes a sterile, wound packing of a flexible material capable of absorbing wound exudate, with the flexible material being in the form of a substantially flat, coiled, spirally-cut layer and a package therefor. In certain embodiments of the invention where it is desired that the wound packing remain in place for an extended period, the flexible material is impregnated with a hydrogel, which may be a "wet" hydrogel (i.e., one containing substantial amounts of water) or a dehydrated hydrogel which is substantially devoid of water but becomes hydrated in use.

摘要： A wound dressing product is described which includes a flexible backing member that can be vacuum formed to include a depression. A pressure-sensitive adhesive layer extends across the depression side of the flexible backing member. A hydrogel material is positioned in the depression of the flexible backing member and a release liner extends over the exposed pressure-sensitive adhesive layer and the exposed hydrogel material, which release liner has a selective releasability whereby it can be removed from the wound dressing product intact, leaving a portion of the pressure-sensitive adhesive and the hydrogel material exposed.

摘要： 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.

摘要： 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.

摘要： 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.
