摘要：
A treatment device (10) comprising: a pump (12), the pump having an inlet side (22) and an outlet side (24), the side pressure lower than atmospheric pressure input, being the side pressure higher than atmospheric pressure out a breathing tube (14) for connection to the patient a pressure sensor (18) adapted to measure the pressure within the breathing tube a valve (16) located between the pump (12) and the breathing tube (14), the valve adapted to selectively connect the breathing tube to the inlet side (22) or the output side (24) being the pump, the valve having a first input (30) connected to the input side (22) of the pump (12) and a second input (32) connected to the output side (24) of the pump (12), the first input (30) a first input port (48) and wherein the second inlet (32) a second input port (62), the valve (16) having a valve member (42) with a valve opening ( 58), the valve member (42) having a central opening (60) connected to the opening of the valve (58), the central opening (60) connected to the breathing tube (14) by the first output being valve (34), wherein the valve member to rotate between a first operating position in which the valve opening (58) superp one first inlet port (48) of the valve and a second operating position in which the valve opening (58) overlies the second input port (62) of the valve a controller (26) adapted to receive a pressure signal from the pressure sensor (18) and to control movement of the valve member (42), wherein the controller (26) is adapted to determine the first operating position as overlapping required between the valve opening (58) and the first input port (48) of the valve in order to provide a predetermined negative pressure within the breathing tube, and to determine the second operating position by overlaying required between the valve opening (58) and the second port (62) upstream of the valve in order to provide a predetermined positive pressure within the breathing tube and in that the treatment de
