In this mode, the piston cylinder rapidly delivers a predetermined amount of gas into the nasal cavity of the user at one time. And to avoid air flow escaping from the user's mouth, the second one-way valve 90 is now closed. When the disposable rapid air supply is finished, the second check valve 90 is restored to the open state, and the user can exhale air.

At this time, a high flow rate of oxygen enters the nasal cavity and is discharged from the oral cavity. In the process, the oxygen in the nasopharynx part is passively fed into the lung through the oxygenation pressure difference in the alveolus so that the user can realize the breath holding time of more than 5 min. After the user releases the breath-holding state, the mode is switched to the mechanical auxiliary ventilation mode through remote control, and the user is helped to accelerate recovery of free breathing.
Specifically, the user adjusts the oxygen supply mode of the breathing control device through the onboard touch display control unit or the remote touch display control unit.
In a preferred embodiment, the second flow rate is 80L/min or higher, and the first flow rate and the third flow rate are less than 80L/min. That is, the speed of the air flow entering from the air inlet is 80L/min or higher, and the air flow overcomes the elastic forces of the first spring 85 and the second spring 95, so that the first check valve 80 is opened and the second check valve 90 is closed.

It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
