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.
Core Innovation
The invention relates to containment devices for intestinal fistulas or ostomies and complex abdominal wounds. A flexible, trimmable and lineal strip forms a fluid containment wall that can be applied at a wound-bed interface. The device includes a sealing flange and an appliance interface flange to create an effluent-tight seal around an opening and to isolate the opening from the wound bed.
The flexible fluid containment wall is configured to collapse under applied negative pressure so the sidewall collapses along an axis perpendicular to a length of the cut lineal strip from a first height to a second height less than the first height. This collapse behavior is used while the sealing flange maintains a seal around the opening to physically isolate the opening from the bed and vacuum suction.
The device is customizable by trimming at least one of the elongate lineal strip, the sealing flange, or the appliance interface flange to provide a cut device of desired size dimensioned to border at least a portion of the opening. The flexible strip and sealing/interface features can be formed into open or closed shapes, joined to create containment areas, and configured to interface with a pouch appliance to capture effluent or bowel contents for disposal.
Claims Coverage
Two independent claims are provided. The claims center on a customizable trimmable flexible elongate lineal strip device with a sealing flange and an appliance interface flange, and on negative pressure collapse of the sidewall from a first height to a second, lower height while forming a seal to physically isolate the opening from the bed.
Customizable trimmable flexible elongate lineal strip with sealing flange and appliance interface flange
providing the customizable device comprising a trimmable and flexible elongate lineal strip comprising a sidewall; a sealing flange extending from a first longitudinal edge of the sidewall; and an appliance interface flange extending from a second longitudinal edge of the sidewall
Trimming to border the opening and sealing to physically isolate the opening from the bed
cutting at least one of the elongate lineal strip, the sealing flange, or the appliance interface flange to provide a cut device of desired size that is dimensioned to border at least a portion of the opening; applying the cut device to the bed such that the cut device borders at least a portion of the opening, and the sealing flange forms a seal around at least a portion of the opening, thereby physically isolating the opening from the bed
Negative pressure collapse of the sidewall from a first height to a second height less than the first height
applying negative pressure to the sidewall to collapse the sidewall along an axis perpendicular to a length of the cut lineal strip from a first height to a second height less than the first height
Customizable cut device configured for negative pressure collapse while forming an isolation seal
wherein at least one of the elongate lineal strip, the sealing flange, or the appliance interface flange is configured to be cut to provide a cut device of desired size that is dimensioned to border at least a portion of the opening; wherein the cut device is configured to be applied to the bed such that the cut device borders at least a portion of the opening; and the sealing flange forms a seal around at least a portion of the opening, thereby physically isolating the opening from the bed; and wherein the cut device is configured to have negative pressure applied to the sidewall to collapse the sidewall along an axis perpendicular to a length of the cut lineal strip from a first height to a second height less than the first height
Across the independent claims, the core inventive coverage is a customizable trimmable flexible elongate lineal strip device with a sealing flange and an appliance interface flange, cut to border an intestinal fistula or ostomy opening, applied to form a seal that physically isolates the opening from the bed, and used with negative pressure to collapse the sidewall from a first height to a second height less than the first height.
