Abstract: A two-cavity pump having a single valve in one cavity and a bidirectional valve in another cavity is disclosed. The pump has a side wall closed by two end walls for containing a fluid. An actuator is disposed between the two end walls and functions as a portion of a common end wall of the two cavities. The actuator causes an oscillatory motion of the common end walls to generate radial pressure oscillations of the fluid within both cavities. An isolator flexibly supports the actuator. The first cavity includes the single valve disposed in one of a first and second aperture in the end wall to enable fluid flow in one direction. The second cavity includes the bidirectional valve disposed in one of a third and fourth aperture in the end wall to enable fluid flow in both directions.

Abstract: A wound fluid collection system includes a canister with a chamber fluidly connected to a wound dressing in a tissue site through an inlet and also fluidly connected to a reduced pressure source through an outlet. At least a portion of the canister is collapsible and yet can be maintained in an extended state when exposed to subatmospheric pressure. The canister is releasably attachable to a supporting member.

Abstract: Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure treatment device to treat a tissue site with reduced pressure may include a pump control unit fluidly separate from a collection unit. Pump energy may be provided by the pump control unit to deflect one or more diaphragms within the collection unit to create reduced pressure. Other systems, devices, and methods are presented.

Abstract: A reduced pressure dressing for applying reduced pressure treatment to a tissue site includes an interface layer adapted to be positioned at the tissue site. An absorbent layer is in fluid communication with the interface layer to absorb liquid from at least one of the interface layer and the tissue site. A pump is in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site. A cover is positioned over the pump, the absorbent layer, and the interface layer to maintain the reduced pressure at the tissue site, and a liquid-air separator is positioned between the absorbent layer and the pump to inhibit liquid from entering the pump.

Abstract: Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

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: 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.

Abstract: A reduced pressure treatment system includes a liquid-collection canister for collecting liquid from a tissue site to which reduced pressure treatment is applied. The canister includes a first space configured to collect the liquid from the tissue site and a filter having a frame and a non-planar filter element. The filter defines a second space within the canister separated from the first space by the filter element. The filter element substantially prevents liquid from passing from the first space into the second space. The filter element substantially allows gaseous communication between the first space and the second space when the second space is exposed to a reduced pressure.
