[0002] In the emergency department, patients may experience breathing difficulties or hypoxia due to various reasons. At this time, oxygen therapy needs to be given in time. With the development of technology, automatic oxygen supply devices have gradually been used in the emergency department. This device can automatically adjust the flow and concentration of oxygen according to the patient's breathing conditions to meet the patient's needs. The emergence of automatic oxygen supply devices not only improves the accuracy and stability of oxygen supply, but also reduces the workload of medical staff.

[0003] When using the oxygen supply device nowadays, most of them are to put the mask on the patient's face first, and then use the oxygen supply device to deliver oxygen into the mask to provide oxygen to the patient. After that, when the oxygen supply device completes the oxygen supply, the oxygen supply device stops delivering oxygen, and then the mask is removed from the patient's face. In this way, the oxygen supply to the patient can be completed. However, if the above steps are in the wrong order, it is easy to cause oxygen leakage. Oxygen leakage may cause the concentration of oxygen inhaled by the patient to be unstable, affecting the treatment effect. In extreme cases, high-concentration oxygen leakage may cause fire or explosion, endangering the life safety of patients and medical staff. Long-term exposure to a high-concentration oxygen environment may have adverse effects on the health of medical staff, such as oxygen poisoning, etc. Oxygen leakage may affect the surrounding environment, such as causing excessive local oxygen concentration and affecting air quality.

[0013] S1: Preparation and inspection before use, check the oxygen reserve in the oxygen tank, turn on the gas cylinder switch, and observe the indication of the oxygen pressure gauge to know the oxygen reserve in the oxygen tank. If the pressure oxygen volume is less than 0.05-0.1MPa, medical oxygen should be supplemented.

[0033] An elastic band 32 is provided on the front of the oxygen mask 31, and two groups of arc-shaped sheets 23 are in contact with the outer side and the inner side of the connecting pipe 19 respectively.

[0034] The oxygen mask 31 can be worn on the patient's face by means of an elastic band 32. After the oxygen mask 31 is worn, the switch of the oxygen tank 1 is turned on, and then the connecting ring 24 movably sleeved on the outside of the connecting tube 19 is pushed, and the connecting ring 24 drives the arc-shaped piece 23 closely attached to the outside of the connecting tube 19 to move, and the two groups of arc-shaped pieces 23 move closely attached to the outside and inside of the connecting tube 19, respectively, so that the "L"-shaped special-shaped tube 21 moves linearly inside the through groove 20, and the special-shaped tube 21 drives the conical nozzle 22 to contact the oxygen mask The air inlet pipe 33 on the back of 31 is detached, and the two groups of arc-shaped pieces 23 after moving can still closely cover the through groove 20 opened inside the connecting pipe 19.

During the movement of the No. 1 protrusion 25, the spring 28 on the outside of the guide rod 27 is in an extruded and deformed state. With the deformation of the spring 28, the No. 1 magnet block 29 embedded in the No. 1 protrusion 25 gradually approaches the No. 2 magnet block 30 embedded in the No. 2 protrusion 26, until the No. 1 magnet block 29 is magnetically attracted to the No. 2 magnet block 30 (the magnetic attraction force of the No. 1 magnet block 29 and the No. 2 magnet block 30 is greater than the elastic force of the spring 28), so that the No. 1 protrusion 25 at the moving position can be positioned, so that the conical nozzle 22 is positioned and suspended in the connecting tube 19;

[0036] Similarly, before oxygen needs to be transported inside the oxygen mask 31, the elastic force of the spring 28 can elastically push the first protrusion 25 away from the second protrusion 26, so that the conical nozzle 22 is sleeved on the intake pipe 33, and the conical nozzle 22 can be used to block the oxygen that needs to enter the intake pipe 33.

8. A method for using an automatic oxygen supply regulator for emergency internal medicine, characterized in that The production device according to any one of claims 1 to 7 is used, comprising the following steps: S1: Preparation and inspection before use, check the oxygen reserve in oxygen tank 1, turn on the gas cylinder switch, and observe the indication of the oxygen pressure gauge to know the oxygen reserve in oxygen tank 1. If the pressure oxygen is less than 0.05-0.1MPa, medical oxygen should be supplemented. S2: After the preparation work is completed, slowly turn on the switch of the oxygen tank 1, adjust it to an appropriate flow rate as needed, and then put the oxygen mask 31 on the patient's face, then pull the connecting block 24 movably sleeved on the outside of the connecting tube 19, so that the two groups of arc-shaped pieces 23 move linearly close to the outer side and inner side of the connecting tube 19 respectively, and the special-shaped tube 21 drives the conical nozzle 22 to move linearly backward inside the connecting tube 19 until the No. 1 magnet block 29 inside the No. 1 protrusion 25 and the No. 2 magnet block 30 inside the No. 2 protrusion 26 are magnetically attracted, so that the conical nozzle 22 is positioned and suspended inside the connecting tube 19. After the conical nozzle 22 is detached from the air inlet pipe 33 that passes through the oxygen mask 31, the oxygen inside the oxygen guide tube 13 can pass through the gap between the conical nozzle 22 and the connecting tube 19 into the air inlet pipe 33 and the oxygen mask 31, so that in the case of an error in the oxygen supply step, the leakage of oxygen can be effectively reduced, and the safety of the use of the oxygen supply device can be effectively improved. S3: The humidified mist generated by the humidifier 34 can be transported to the special-shaped tube 21 by using the air delivery pipe 35, and sprayed into the connecting tube 19 by the conical nozzle 22. The humidified mist sprayed by the conical nozzle 22 enters the oxygen mask 31 along with the oxygen, which can reduce the dry oxygen that may cause the patient's respiratory mucosa to dry out and cause discomfort.
