Abstract: A wound dressing includes a superabsorbent pad, a drape layer, a humidity chamber, a wick, and a humidity colorimeter sensor. The superabsorbent pad is configured to absorb wound fluid and has a first side and a second, wound- facing side. The drape layer is coupled to the first side of the superabsorbe nt pad and has a first side and a second, wound- facing side. The drape layer is substantially impermeable to liquid and substantially permeable to vapor. The humidity chamber is coupled to the first side of the drape layer opposite the superabsorbent pad. The wick extends through the drape layer and is configured to wick moisture between the superabsorbent pad and the humidity chamber. The humidity colorimeter sensor is located within the humidity chamber and configured to change color responsive to a humidity level within the humidity chamber.

Abstract: A dressing for treating a tissue site with negative pressure, a sealing tape, methods of use and methods of manufacturing the sealing tape are described. The dressing includes a tissue interface configured to be positioned adjacent to the tissue site and a sealing member configured to be positioned over the tissue interface and the tissue site to form a sealed environment. The dressing also includes a sealing tape having a carrier layer having a first side and a second side, a silicone adhesive layer bonded to the first side of the carrier layer, and an acrylic adhesive layer bonded to the second side of the carrier layer. A plurality of holes extend through the silicone adhesive layer, the acrylic adhesive layer, and the carrier layer. A first release liner is coupled to silicone adhesive layer, and a second release liner is coupled to the acrylic adhesive layer.

Abstract: Methods, apparatuses, and systems for determining a pressure in a sealed therapeutic environment provided by a dressing are described. The system can include a tissue interface configured to be positioned adjacent a tissue site. At least a portion of the tissue interface is electrically conductive. The system also includes a sealing member configured to be disposed over the tissue interface to form the sealed therapeutic environment. The system includes a dressing interface configured to fluidly connect the sealed therapeutic environment with a therapy unit. The dressing interface is further configured to be electrically coupled to the tissue interface and the therapy unit.

Abstract: A reduced pressure treatment system includes a porous pad positioned at a tissue site and a canister having a collection chamber, an inlet, and an outlet. The inlet is fluidly connected to the porous pad. A reduced pressure source is fluidly connected to the outlet of the canister to such that fluid from the tissue site may be drawn into the collection chamber. A hydrophobic filter is positioned adjacent the outlet to prevent liquid from exiting the collection chamber through the outlet. A baffle is positioned within the canister to create a tortuous path between the inlet and the outlet to prevent premature blocking of the hydrophobic filter.

Abstract: Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described. Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. A pneumatic actuator may be mechanically coupled to a disposable distribution system that can provide a fluid path between the solution source and a distribution component. A bacterial filter may be disposed in the fluid path between the actuator and the distribution component to prevent contamination of the actuator during operation. The distribution system may be separated from the actuator and disposed of after operation, and the actuator may be re-used.

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.

Abstract: Systems, apparatuses, and methods for utilizing a dressing having a single manifold fluidly coupled to at least two therapy units in a negative-pressure therapy and/or instillation therapy environment as set forth herein. In one example embodiment wherein the therapy system comprises two therapy units, apparatus and methods may be utilized for alternately applying pressure or fluids to a single tissue site to more quickly remove large amounts of fluid from the tissue site.

Abstract: A wound fluid collection system includes a canister adapted to collect bodily fluids from a tissue site. The canister includes an acoustic transducer adapted and positioned to insonify a cavity within the canister, the cavity being defined by a wall of the canister and the bodily fluids collected within the canister. A resonant frequency may be calculated based on a resulting received signal from the insonification. The resonant frequency may indicate a volume of the cavity within the canister. The difference between a known volume of the canister and the calculated volume of the cavity provides the volume of bodily fluid collected in the canister.
