  • Patent number: 11523932
    Abstract: A skin-safe effluent containment system that may be used to contain fluid leakage from openings in the body of a patient and will adhere to skin in any condition: healthy or injured, wet or dry, smooth, scarred, or uneven. Fluid leakage can occur from natural orifices such as the anus and vagina, spontaneously formed enteric fistulas, rectovaginal fistulas, and surgical openings such as ileostomy and colostomy stomas. The system includes a vacuum-adherent pouch device, comprised of a pouch connected to a porous foam ring which has an air-permeable contact layer on its bottom surface and an air seal on its top surface. The inner and outer perimeters of the foam ring are enclosed and sealed with skin-adhesive materials. When placed on the patient, negative pressure (vacuum) is applied to the foam ring so that the foam collapses and compresses the vacuum-adherent pouch device down against the patient's skin.

  • Patent number: 11207097
    Abstract: A device, system, kit, and method for managing the passage of fluid through an opening in the body of a patient that includes a fluid-containment receptacle including a collapsible sidewall, the fluid-containment receptacle having a first receptacle opening and a second receptacle opening positioned at opposite ends of the sidewall, the fluid-containment receptacle. The device also including a first flange extending radially outward from the sidewall and positioned at or adjacent to the first receptacle opening and a second flange extending radially outward from the sidewall at or adjacent to the second receptacle opening. The device is configured to be applied to the opening in the body of the patient such that the first opening and the first flange contact the body of the patient and form a fluid barrier around the opening.

  • Publication number: 20210106737
    Abstract: A NPWT wound care device for treatment of large wounds with negative pressure that includes an open-cell porous foam layer, a skin-safe fluid-permeable contact layer on a bottom surface of the foam layer that is configured to be placed in direct contact with an open wound of a patient, and a top air-sealed layer on an upper surface of foam opposite of the fluid-permeable contact layer. The wound care device defines an outer perimeter along an edge of the foam layer that includes a skin-safe adhesive and is configured to form an air-tight seal in conjunction with the air-sealed layer against a patient's skin.

  • Patent number: 10660786
    Abstract: Devices to contain and control the effluent or gastric juices of intestinal fistulas, other fistulas, stomas, and other wounds. The device includes a flexible fluid containment lineal strip defining a fluid containment wall which collapses when pressure is applied to the wound dressing, means for forming the lineal strip into any open or closed shape to fit wounds of various shape and size, means for joining the lineal strip to create closed effluent containment areas, means for creating a seal at the wound bed interface whereby effluent is contained, and means for interfacing with a pouch appliance to capture effluent and bowel contents until bowel contents can be emptied into a toilet or other waste receptacle.

  • Patent number: 9078990
    Abstract: An enteric fistula healing device, configured for application over a fistula or other wound to physically separate the fistula from the remainder of the wound area, such that any effluent from the intestine or bowel, or other enteric substances, that pass through the fistula are prevented from communicating with the wound area. The device is configured to collapse from a first height to a shorter second height.
