发明名称 VENTILATOR AND OPERATION METHOD THEREFOR
摘要 <P>PROBLEM TO BE SOLVED: To provide a ventilator which is compact and low power consumption, and an operation method therefor. <P>SOLUTION: Specifically disclosed is a ventilator 100 wherein a control unit 17 switches back and forth between a first state in which the inspired gas stored in a reservoir tank 4 is delivered to a patient and a second state in which the expiration of the patient is relieved by controlling the driving of valve mechanisms 5, 8. A pressure pump 1 has discharge performance for recovering the pressure reduction in the reservoir tank 4 caused by the inspiration during expiration time. Here, the necessary inspired air can be supplied to the reservoir tank 4 with a low capacity pressure pump by setting the expiration time (second time) to a length of not less than inspiration time (first time). As a result, the capacity of the pressure pump 1 and reservoir tank 4 can be reduced, and the driving power of the pressure pump 1 can be cut. <P>COPYRIGHT: (C)2011,JPO&INPIT
