    Abstract: Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

    Abstract: A system that may be adapted to distribute reduced pressure to a tissue site may include a dressing and a sealing member. The dressing may include a manifold layer, a storage layer, and a plurality of retainers. The manifold layer may be adapted to be positioned proximate the tissue site, and the storage layer may be positioned proximate the manifold layer. The plurality of retainers may be disposed in the storage layer. Each of the retainers may define a fluid communication channel through the storage layer. The retainers may be adapted to substantially preclude deformation of the storage layer into the fluid communication channels. The sealing member may be adapted to cover the dressing and to provide a fluid seal between the sealing member and the tissue site.

    Abstract: A conduit for treating a tissue site with reduced pressure may include a primary lumen and at least one secondary lumen. A wall of the conduit may include a first wall material and a second wall material. The first wall material may comprise a substantially non-absorbent material that is vapor impermeable and liquid impermeable. The second wall material may comprise an absorbent material that is vapor permeable and liquid impermeable. The second wall material may be positioned in fluid contact with the at least one secondary lumen. Other systems, apparatus, and methods are disclosed.

    Abstract: Systems, methods, and apparatuses for providing instillation therapy with a negative-pressure source are described. The apparatus can include a housing having a dosing chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus can also include a moveable barrier disposed in the housing between the dosing chamber and the negative-pressure chamber. The housing includes a fluid inlet in fluid communication with the dosing chamber and a fluid outlet in fluid communication with the dosing chamber. The housing can also include a negative-pressure inlet in fluid communication with the negative-pressure chamber and a biasing element coupled to the moveable barrier. The biasing element is operable to move the moveable barrier between a charge position and a discharge position.

    Abstract: Systems, methods, and apparatuses for providing installation therapy and negative-pressure therapy are described. The apparatus includes a housing and a moveable barrier disposed in the housing to form a dosing chamber and a pressure chamber. The apparatus also includes a therapy conduit configured to be fluidly coupled to a pressure source and to a canister. The apparatus further includes a fluid inlet fluidly coupled to the dosing chamber and configured to be fluidly coupled to a fluid source and a fluid outlet fluidly coupled to the dosing chamber and configured to be fluidly coupled to a dressing. A pressure inlet is fluidly coupled to the therapy conduit and the pressure chamber; and a check valve is disposed in the therapy conduit.

    Abstract: Systems, apparatuses, and methods for providing a negative-pressure therapy system are described. The system includes a first dressing, a second dressing, and a negative-pressure source. The negative-pressure source includes a first pump and a second pump. A first valve is fluidly coupled to the first dressing and the first pump to selectively permit fluid communication to the first dressing. A second valve is fluidly coupled to the second dressing and the second pump to selectively permit fluid communication to the second dressing. A cross-over valve is fluidly coupled to the first pump, the first valve, the second pump, and the second valve. The cross-over valve permits fluid communication between the first pump and the second valve and/or the second pump and the first valve. A controller is communicatively coupled to the first pump, the second pump, the first valve, the second valve, and the cross-over valve for operating the same.
