Provided is a negative-pressure closure therapy device with which an adequate suction flow rate can be used to apply, when necessary, negative pressure to a closed space formed by a wound dressing and a wound area, even if a pump device is miniaturized. In this therapy device (100), a pump device (30) having a high suction flow rate is fitted to a wound dressing (10) at times of extraordinary use when a high suction flow rate is necessary, and air is sucked from a closed space (904) formed by a wound area (903) and the wound dressing (10). Accordingly, an adequate suction flow rate can be ensured at times of extraordinary use, even if a pump device (20) for everyday use is miniaturized and the suction flow rate of the pump device (20) is reduced. As a result, the pressure value of the closed space (904) can be reduced to a desired value more swiftly. |
