According to the current physical condition and oxygen absorption capacity of the patient, the threaded rod 16 can be adjusted through the valve head 18 to control the spacing angle of the closing piece 17 in the adjustable valve body 13, so as to achieve the purpose of controlling the oxygen flow, thereby improving the utilization rate of oxygen and reducing the waste of oxygen during oxygen supply.

As shown in Figures 1, 2 and 3, a fixing bolt 2 is passed through the outside of the mask body 1, and one end of the fixing bolt 2 is movably connected to a first elastic band 3, and a second elastic band 4 is arranged below the first elastic band 3. The first elastic band 3 and the second elastic band 4 are convenient for patients with different head sizes to wear the device, thereby improving the overall application range of the device. The first elastic band 3 is threadedly connected to the mask body 1 through the fixing bolt 2, and the fixing bolt 2 is symmetrically arranged with the central axis of the mask body 1. The first elastic band 3 also allows the mask body 1 to fit the patient's face more closely, reducing the probability of oxygen leakage during the oxygen supply process of the device. A ventilation tube 5 is fixedly installed on one side of the mask body 1, and a pipe cover 6 is fixedly installed on the outside of the ventilation tube 5. The ventilation tube 5 and the pipe cover 6 on the mask body 1 can be appropriately opened when the patient breathes oxygen, so that the device becomes a complete breathing system, allowing the patient to expel exhaled carbon dioxide through the ventilation tube 5, preventing the patient from inhaling the exhaled carbon dioxide into the body for the second time, resulting in the problem of carbon dioxide retention.

As shown in Figures 1, 4 and 5, the adjustable valve body 13 is threadedly connected to the oxygen tube 10 through the fastening bolts 12, and the fastening bolts 12 are evenly spaced on the flange 11.

The practical working principle of the present invention is as follows: firstly, an external power source is connected to stretch the first elastic band 3 and the second elastic band 4 to wear the device on the face of the patient who needs oxygen inhalation. The first elastic band 3 and the second elastic band 4 allow the mask body 1 to fit the patient's face more closely, thereby reducing the probability of oxygen leakage during the oxygen delivery process of the device. Then, the fixed pipe sleeve 15 of the oxygen delivery tube 14 is connected to the oxygen supply device. After the preparation work is completed, the oxygen supply device can be started to allow oxygen to be delivered to the patient through the oxygen delivery tube 14. When the patient is inhaling oxygen, the threaded rod 16 can be adjusted through the valve head 18 to control the spacing angle of the sealing piece 17 in the adjustable valve body 13 according to the current physical condition and oxygen inhalation capacity of the patient, so as to achieve the purpose of controlling the oxygen flow rate. This improves the utilization rate of oxygen and reduces the oxygen leakage during oxygen delivery. The patient then opens the ventilation tube 5 and the tube cover 6 on the mask body 1 to make the device a complete breathing system, so that the patient can expel the exhaled carbon dioxide through the ventilation tube 5, preventing the patient from re-inhaling the exhaled carbon dioxide into the body, which causes the problem of carbon dioxide retention. In this way, even for patients with weaker physical conditions, the oxygen supply and the patient's oxygen inhalation flow rate can be well controlled, assisting the doctor to complete the patient's physical treatment. Finally, after completing the wearing and oxygen supply of the device according to the above operations, turn off the external power supply and unplug the oxygen supply tube 14 connected to the oxygen supply device, and remove the oxygen tube 10 through the threaded tube 8 and the threaded sleeve 9 for daily disinfection and cleaning. In this way, the use process of the flow-adjustable oxygen supply mask is completed.
