Abstract: Systems, apparatuses, and methods for providing negative pressure to a tissue site are closed. Illustrative embodiments may include a system comprising a dressing having tissue interface in fluid communication with the tissue site. Such system may also comprise a canister having a fluid inlet fluidly coupled to the canister and an ambient inlet fluidly coupled to ambient air outside the collection chamber. Such system may further comprise a first outlet fluidly coupled to the canister and adapted to receive negative pressure from a source of negative pressure, and a second outlet. Such system also may comprise a fluid conductor fluidly coupled between the second outlet and the tissue interface, wherein the fluid conductor may be adapted to deliver ambient air to the tissue site. In some embodiments, such system may also comprise a regulator fluidly coupled between the second outlet and the ambient inlet, wherein the regulator is adapted to provide ambient air through the fluid conductor to the tissue site in a controlled fashion.

Abstract: In some embodiments, a dressing assembly may include a dressing bolster, an interface seal, and a base layer. The dressing bolster may include a first side, a second side, and a periphery. The interface seal may be coupled at the periphery of the dressing bolster. The base layer may include a base layer flange configured to be coupled to the dressing and to extend beyond the periphery of the dressing bolster. The dressing assembly may be suitable for treating a tissue site with reduced pressure and for creating an apposition force between a first portion of the tissue site and a second portion of the tissue site. Other systems, apparatus, and methods are disclosed.

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 sampling interface may comprise an inlet port, an outlet port, and a sampling chamber between the inlet port and the outlet port. The apparatus may also comprise a sampling port and at least one split seal between the sampling port and the sampling chamber. The split seal may comprise a first sealing member and a second sealing member that converge to a sealing line. The apparatus may additionally include at least one fluid collection channel disposed interior to the split seal. A lateral flow strip for sampling fluid removed from a tissue site may comprise an acquisition surface and a migration medium fluidly coupled to the acquisition surface. At least one test medium may be fluidly coupled to the migration medium, and a liquid-impermeable cover may enclose the migration medium and the test medium. The acquisition surface is preferably not enclosed.

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: A system, method, and apparatus for treating a tissue site with reduced pressure includes a dressing adapted to be positioned proximate the tissue site. An absorbent may be adapted to be fluidly coupled to the manifold, and an ion exchange member may be adapted to be fluidly coupled between the manifold and the absorbent. A sealing member may be adapted to cover the tissue site to form a sealed space having the manifold disposed therein. A reduced-pressure source may be adapted to be fluidly coupled to the manifold.

Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. At least one of the apertures in the periphery may be positioned at an edge of the periphery, and may have an interior exposed at the edge. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer.

Abstract: Pump cassettes, wound-treatment apparatuses and methods. In some embodiments, a pump cassette comprises: a pump body having a pump chamber, an inlet valve in fluid communication with the pump chamber, and an outlet valve in fluid communication with the pump chamber; a diaphragm coupled to the pump body such that the diaphragm is movable to vary a volume in the pump chamber; and an identifier configured to store one or more properties of the pump cassette such that the identifier is readable by an automated reader to determine the one or more properties. In some embodiments, the pump cassette is configured to be removably coupled to a wound-treatment apparatus having an actuator such that the actuator can be activated to move the diaphragm.
