  • Method And System To Evacuate One Or More Dressings Using Two Or More Vacuum Pumps
    Publication number: 20190110946
    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.
