[0071] Through the rapid vacuum pump 5, it is convenient to quickly generate negative pressure in the negative-pressure circular waste gas recovery chamber 3, so as to enable a patient who has lost the breathing function to exhale. The gas exhaled by the patient is transmitted to the waste gas recovery pipeline 8 through the breathing connection part 10. The waste gas recovery pipeline 8 is connected to the inlet end of the negative-pressure circular waste gas recovery chamber 3. Under the action of the negative pressure in the negative-pressure circular waste gas recovery chamber 3, the gas exhaled by the patient entering the waste gas recovery pipeline 8 enters the negative-pressure circular waste gas recovery chamber 3 and is discharged from the outlet of the negative-pressure circular waste gas recovery chamber 3, thus realizing the exhalation function for a patient who has lost the breathing function; through the negative-pressure chamber 31 intake throttle 14 and the intake switch control valve 15, it is convenient to control the gas exhaled by the patient to enter the negative-pressure circular waste gas recovery chamber 3; through the negative-pressure chamber outlet throttle 16, it is convenient to control the gas exhaled by the patient entering the negative-pressure circular waste gas recovery chamber 3 to be discharged;

[0072] Through the air pressure control valve 17, it is convenient to regulate the volume air pressure and / or vacuum degree in the high-pressure circular gas supply chamber 2 or the negative-pressure circular waste gas recovery chamber 3, so as to facilitate regulating the patient's inhalation volume or the patient's exhalation volume; at the same time, through the air pressure control valve 17, it is convenient to regulate the air pressure and flow rate of the gas entering the patient's respiratory system or regulate the air pressure and flow rate of the gas exhaled by the patient's respiratory system, so as to facilitate regulating the total gas volume of each breath of the patient;

[0073] By controlling the processor 18 and the timer 19, it is convenient to form the control system of the oxygen supply machine. Each component connected to the control processor 18 works under the control instruction of the control processor 18; through the timer 19, it is convenient to control the working states of the working components for forcing the patient to inhale and the working components for forcing the patient to exhale under the time interval set by the timer 19 through the control processor 18, so as to realize the control of the time intervals of the patient's exhalation and inhalation according to the time interval set by the timer 19.

[0074] In this solution, the two-way forced pulmonary circulation oxygen supply machine can not only provide inhaled oxygen for the patient to inhale, but also, for patients with respiratory failure, when the patient is about to lose the respiratory function, force the patient to perform the inhalation function and the exhalation function, so as to force the patient's lungs to expand, which is equivalent to performing cardiopulmonary resuscitation on the patient's body, facilitating the improvement of the success rate of rescuing the patient and enabling the patient to obtain the best rescue effect.

[0075] The oxygen supply machine of this embodiment can be applied to the following aspects:

[0076] I. Patients who have lost the ability of autonomous breathing;

[0077] II. Patients who need cardiopulmonary resuscitation;

[0078] III. People or groups in dangerous environmental conditions, such as in a closed environment containing the novel coronavirus, or at high altitudes with low oxygen, or in an oxygen-free deep sea or outer space of the earth.

[0079] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications without creative contributions to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
