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 and methods for treating a plurality of tissue sites include a multi-port therapy unit. The multi-port therapy unit includes a plurality of patient-side ports each fluidly coupled to a plurality of conduits and a fluid reservoir fluidly coupled to the plurality of ports. A plurality of pressure sensors are associated with the plurality of patient-side ports to determining a pressure associated with each conduit. A controller is operatively coupled to the plurality of pressure sensors to receive treatment pressure data, monitor pressure for each pressure sensor of the plurality of pressure sensors, and signal an alarm condition if the pressure is outside of a pre-selected range. The system includes a reduced-pressure source fluidly coupled to a dressing at each tissue site through the multi-port therapy unit.

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.

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: Systems and apparatuses for administering reduced pressure treatment to a tissue site including a wound filler for positioning adjacent a wound site on a patient. The wound filler includes at least one strand having a plurality of nodes positioned along a length of the strand. The at least one strand has a charged state and an uncharged state. In the charged state, the at least one strand includes a stored energy that when released would deform or move the at least one strand. In the discharged state, the stored energy has been released. The wound filler further includes a removable sheath encasing the at least one strand. The at least one strand transitions from the charged state to the uncharged state as the removable sheath is removed.

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 superabsorbent 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.
