Abstract
Systems, methods, and devices are disclosed that involve a fistula-isolating device for use when reduced pressure is applied to a wound bed having a fistula. In one instance, the fistula-isolating device includes an adjustable passageway member and a perimeter member that contracts under reduced pressure and that automatically accommodates wound beds of different heights. In another instance, the fistula-isolating device involves a body shaped as a frustro-conical body that is readily sized for different depth wound beds. Other systems, methods, and devices are presented.
Claims14
A system for providing reduced pressure treatment to a wound bed that includes a fistula, the system comprising:
- a fistula-isolating device for isolating the fistula in the wound bed undergoing reduced-pressure treatment, the fistula-isolating device comprising:
- a body that is substantially frusto-conical in shape and having a passageway and having a first end and a second end, and
- a perimeter member positioned substantially around an exterior of the body and substantially along a length of the body,
- wherein at least a portion of the body defining the passageway is fluid impermeable;
- a distribution manifold having a fistula aperture for receiving the fistula-isolating device;
- a sealing member for covering the fistula-isolating device and the distribution manifold to create a sealed space over at least a portion of the wound bed, wherein the sealing member has an ostomy-interface aperture;
- a reduced-pressure source for supplying a reduced pressure to the sealed space;
- and
- an ostomy appliance fluidly coupled to the fistula-isolating device.
A fistula-isolating device for isolating a fistula in a wound bed undergoing reduced-pressure treatment, the fistula-isolating device comprising:
- a body that is substantially frusto-conical in shape and having a plurality of segments and a passageway;
- wherein at least a portion of the body defining the passageway is fluid impermeable;
- and
- wherein at least one of the plurality of segments is adapted to be removed for adjusting a height of the body of the fistula-isolating device.
