Abstract: A treatment system for applying negative pressure therapy and fluid instillation treatment to a tissue site, particularly an abdominal tissue site, is disclosed. In some embodiments, the treatment system may include a dressing member, a plurality of fluid removal pathways, a fluid instillation matrix, a drape, a negative-pressure source, and a fluid instillation source. Instillation fluid may be delivered from the fluid instillation source to the tissue site through the fluid instillation matrix, and negative pressure may be communicated and fluid withdrawn from the tissue site through the plurality of fluid removal pathways.

Abstract: A negative pressure wound treatment (NPWT) system including a NWPT therapy unit and a wound dressing configured to overlay a wound bed. The NPWT system includes a first length of tubing comprising a first end and a second end, the first end of the first length of tubing coupled to the NWPT therapy unit and the second end of the first length of tubing having a first coupling half, as well as a second length of tubing having a first end and second end, the first end of the second length of tubing coupled to the wound dressing and the second end of the second length of tubing having a second coupling half. The NPWT system includes an inline filter comprising a sintered polymer and a superabsorbent material, and an inline coupling, wherein the inline coupling is configured to operably couple and de-couple the NPWT therapy unit and wound dressing.

Abstract: A dressing includes an evaporative film layer having a wound-facing side and a non-wound¬ facing side. The evaporative film layer has a high moisture vapor transfer rate. The dressing includes a carrier film layer coupled to the non-wound-facing side of the evaporative film layer. A plurality of holes extends through the carrier film layer. The dressing includes a superab sorbent layer coupled to the wound-facing side of the evaporative film layer and a wicking layer coupled to the superab sorbent layer. The superab sorbent layer is positioned between the wicking layer and the evaporative film layer. The wicking layer is configured to wick fluid from a wound, the superab sorbent layer is configured to absorb fluid from the wicking layer, and the evaporative film layer and the carrier film layer allow evaporation of fluid from the superabsorbent layer through the holes. The carrier film layer provides structural support to the evaporative film layer.
