[0002] With the rapid development of my country's social economy, the trend of population aging is becoming increasingly obvious and the degree of aging is becoming increasingly serious. The incidence of respiratory failure in the elderly is increasing. Oxygen inhalation is usually used to improve the symptoms of respiratory failure, especially for patients with chronic diseases such as cardiology and respiratory medicine. They usually need to inhale oxygen for several days to increase the level of arterial oxygen partial pressure and oxygen saturation, correct hypoxia, and promote metabolism.

[0003] The most widely used oxygen supply equipment on the market is the oxygen mask. For example, patent document CN203355076U discloses an oxygen supply mask, which is mainly composed of a mask, a nose clip, an elastic band, a universal connector and an oxygen tube. When in use, the mask is placed on the patient's face, the mouth and nose are sealed, and the mask is fixed to the patient's head with an elastic band for oxygen inhalation.

[0004] The defects of the above oxygen masks are: 1. When the patient needs to breathe through the nasal cavity, there is a problem of insufficient oxygen supply because the inlet of the oxygen tube is far away from the nostrils. Generally, medical staff will use nasal catheters to supply oxygen. When the patient's nasal cavity is blocked or damaged, the oxygen mask needs to be replaced again, which is cumbersome and increases the workload of medical staff; 2. The material of the oxygen mask is relatively hard, which can easily cause pressure damage to the patient's face, and it cannot fit the face, which is prone to leakage and affects the maintenance of oxygen saturation; 3. The elastic band is tied behind the patient's head to fix the oxygen mask, making it inconvenient to adjust the tightness. Utility model content:
