Therefore, the oxygen supply system is widely used in hospitals to supply oxygen.

[0003] For example, the patent document with publication number CN111346286A discloses a medical oxygen automatic supply system, which comprises: a first liquid oxygen tank, a first air heat exchanger, a first liquid oxygen tank outlet connected to the first liquid oxygen tank, used for heating the liquid oxygen output from the first liquid oxygen tank; a first temperature detector arranged at the outlet of the first air heat exchanger, used for detecting the temperature of the oxygen heated by the first air heat exchanger; an oxygen supply port connected to the outlet of the first air heat exchanger through a conveying pipeline; a total outlet regulating valve arranged on the conveying pipeline; a monitoring device connected to the total outlet regulating valve and the first temperature detector, respectively, used for controlling the opening of the total outlet regulating valve and the oxygen supply through the oxygen supply port when the oxygen temperature detected by the first temperature detector is higher than or equal to the room temperature, effectively improving the efficiency of oxygen supply.

[0004] The above technical scheme can realize automatic oxygen supply and ensure the efficiency of hospital oxygen supply, but in the actual medical activities of the hospital, the actual demand of oxygen usually fluctuates with different medical activities, when the oxygen demand in the hospital is large, the actual supply of the oxygen supply system cannot meet the actual demand of oxygen, which can easily cause fluctuations in the oxygen supply process, reduce the reliability of oxygen supply and affect the normal medical activities.
