Abstract:
1. A closed wound dressing system comprising: a layer of moisture permeable gel for application to an upper surface of a wound area and forming a cavity in the gel layer that is open to a wound adjacent to the lower surface of the gel layer, the gel layer being sized to extend beyond the upper surface of the wound area to cover and extend over the wound area without extending into the wound area for attachment to healthy skin outside the wound area, the lower surface of the gel layer adhering to the healthy skin around the wound area without the use of adhesives, the gel layer is permeable to moisture, tubing having an inner conduit, a distal end and a proximal end, a distal end portion of the tubing extending into the cavity, the tubing being attached to a gel sealant and extending into the cavity formed in the gel layer, a vacuum pump attached to the proximal end of the tubing to apply a negative pressure to the inner conduit, a porous material attached to the lower surface of the gel layer extending across an opening to the cavity below the distal end of the tubing without extending into the wound area so that material drawn from a wound into the tubing passes through the porous material, a porous packing packed in the cavity in the gel layer without extending into the wound area; and a container connected to a proximal end portion of the tubing to accept material drawn into the tubing from a wound.
