  • WOUND EXUDATE REMOVAL AND ISOLATION SYSTEM
    Publication number: 20140135719
    Abstract: A wound exudate removal and isolation system includes a porous dressing, a canister in fluid communication with the dressing, and a first valve positioned between the dressing and the canister. The first valve is positionable between an open position and a closed position. A disposal line is fluidly connected to the canister and includes a second valve that is positionable between an open position and a closed position. A pump is fluidly connected to the canister and is configured to draw wound exudate from the dressing into the canister when the first valve is open and the second valve is closed. The pump is configured to force wound exudate from the canister into the disposal line when the first valve is closed and the second valve is open.

  • Reduced pressure treatment system having blockage clearing and dual-zone pressure protection capabilities
    Publication number: 20080071234
    Abstract: A method of treating a tissue site is provided. The method includes applying a reduced pressure to a tissue site with a reduced pressure source. A source pressure is monitored at the reduced pressure source, and a differential pressure is determined between the source pressure and the desired tissue site pressure. If a blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a first maximum differential pressure. If no blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a second maximum differential pressure.
