Abstract: A reduced pressure treatment system includes a compressible chamber positionable beneath a foot of a user and being movable between an expanded position and a compressed position. The compressible chamber includes an inlet and an outlet. An inlet valve is in fluid communication with the inlet to prevent fluid within the compressible chamber from exiting the inlet, and an outlet valve is in fluid communication with the outlet to prevent fluid from entering the compressible chamber through the outlet. A biasing member is disposed within the compressible chamber to bias the compressible chamber toward the expanded position, and a manifold is positionable at a tissue site and in fluid communication with the inlet of the compressible chamber.

Abstract: Systems and methods for a reduced-pressure interface for connecting a multi-lumen conduit to a distribution manifold. The interface includes a housing having a flange portion and a cavity wall portion. The cavity wall portion forms a cavity having a tissue-facing cavity opening. The interface further includes an attachment device, a conduit port, and a multi-lumen conduit. The attachment device is coupled to a tissue-facing side of the flange portion for coupling the housing to a sealing member. The conduit includes a distal end and a proximal whereby the distal end extends through a conduit aperture and past the cavity wall portion into the cavity. The conduit further includes a primary lumen and a plurality of sensing lumens. The primary lumen and the plurality of sensing lumens extend from the proximal end of the conduit to the distal end. The conduit is adapted to contact the distribution manifold.

Abstract: A disc pump valve for controlling the flow of fluid through a disc pump includes a first plate having first plate apertures and a second plate having second plate apertures both extending generally perpendicular through the first plate and the second plate, respectively. The second plate apertures are substantially offset from the first plate apertures. The disc pump valve also includes a sidewall disposed between the first plate and second plate. A valve flap is disposed and moveable between the first plate and second plate. The valve flap includes flap apertures substantially offset from the first plate apertures and substantially aligned with the second plate apertures, and low-mass areas. The low-mass areas are offset from the first plate apertures and second plate apertures. The valve flap moves between the first plate and second plate in response to a change in direction of differential pressure of the fluid outside the valve.

Abstract: A reduced-pressure treatment system for treating a wound on a patient includes a composite manifold that may help prevent or minimize injury to a wound edge of the wound being treated with reduced pressure. The composite manifold includes a perimeter manifold member and an inboard manifold member. The perimeter manifold member is designed to not collapse substantially under reduced pressure in a therapy range. The perimeter manifold member may be more rigid with respect to compressibility than the inboard manifold member. A sealing member is used to form a fluid seal over the wound, and a reduced-pressure subsystem provides reduced pressure to the composite manifold. Other systems, methods, and dressings are presented.

Abstract: The illustrative embodiments described herein are directed to apparatuses, systems, and methods for managing liquid flow associated with a tissue site that involves using reduced pressure to control fluid flow. In one instance, an apparatus includes a first valve and a second valve in fluid communication with a reduced-pressure source. The valves are movable between an open position and a closed position and are operable to change flow status (open to closed or vice versa) based on a presence of reduced pressure. At least one of the first valve or the second valve is in the closed position to obstruct a flow of a liquid while the other is in the open position. The apparatus also includes a reservoir fluidly coupled to the first valve and the second valve. Other systems, methods, and apparatuses are presented.
