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: A system is described herein that can irrigate a tissue site using negative-pressure. The system may include a tissue interface configured to be placed adjacent to the tissue site, and a sealing member configured to be placed over the tissue interface to form a sealed space. The system may also include a negative-pressure source configured to be fluidly coupled to the sealed space and a fluid source. The system may further include an irrigation valve. The irrigation valve can have a fluid inlet configured to be fluidly coupled to the fluid source. The irrigation valve can also have a fluid outlet configured to be fluidly coupled to the sealed space. The irrigation valve may also include a clamp configured to be actuated by the negative-pressure source to regulate fluid flow from the fluid source through the fluid outlet.

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 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 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: 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 for providing therapy to a tissue site is described. The system can include a light sensor, a motion sensor, and a controller. The controller can be communicatively coupled to the source of negative pressure, the light sensor, and the motion sensor. In some embodiments, the controller can be configured to receive a first signal from the light sensor indicative of ambient light, receive a second signal from the motion sensor indicative of activity, and activate alert based on the first signal and the second signal.

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.
