[0025] It is worth mentioning that the other ends of the two quick connectors 8 are connected to two pipes, through which the patient can inhale and exhale. One of the valves 9 is an inhalation valve, which is opened during inhalation and closed during exhalation, and the other valve 9 is an exhalation valve, which is opened during exhalation and closed during inhalation.

[0026] Specifically, the gas control regulating valve 3 is a control switch for controlling the switching between mechanical ventilation and manual ventilation modes, and the APL valve 4 is used to adjust the pressure in the breathing circuit body 1 .
