Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
A kind of anaesthetic circuit device, including inspiratory valve 2, mask 5, expiratory valve 6 and the suction being sequentially connected with tracheae 13
Receiving apparatus 8, is connected with Y shape connector 4 between the right end of the inspiratory valve 2 and the right end of expiratory valve 6, the connection wye 4 connects
The both ends of inspiratory valve 2 and expiratory valve 6 are equipped with screwed pipe 3, and another termination of the connection wye 4 mask 5 is described
