    Abstract: Provided is a negative-pressure wound therapy apparatus capable of causing negative pressure in a closed space defined by a wound dressing and a wound region with a sufficient suction flow rate as needed even with a miniaturized pump device. In atypical use that needs a high suction flow rate, because a pump device (30) with a high suction flow rate is attached to a wound dressing (10) and sucks gas from a closed space (904) defined by a wound region (903) and the wound dressing (10), even when a pump device (20) for typical use is miniaturized and the suction flow rate of the pump device (20) is reduced, a therapy apparatus (100) can achieve a suction flow rate sufficient for atypical use. Thus, the pressure value in the closed space (904) can decrease to a desired value more quickly.

  • Patent number: 10188581
    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.
