  • Publication number: 20230390116
    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source to the tissue site through the fluid instillation matrix, and negative pressure may be communicated and fluid withdrawn from the tissue site through the plurality of fluid removal pathways.

  • Publication number: 20210393442
    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.

  • Publication number: 20210267807
    Abstract: A system for treating a deep abdominal wound. The system includes a wound dressing. The wound dressing includes a visceral-protective layer, a compressive layer, and a sealing layer. The visceral-protective layer is configured to be positioned in an open abdomen. The compressive layer is configured to be disposed proximate to the visceral-protective layer. The compressive layer includes a pattern of voids configured for anisotropic collapse of the compressive layer when under negative pressure. The sealing layer is configured to form a sealed space in the open abdomen. A negative pressure source configured to provide negative pressure to the compressive layer.
