Background

Oxygen therapy is a common treatment method in clinic and can assist in treating various diseases. The oxygen mask commonly used in clinic at present is usually provided with a breathing regulator, but the oxygen mask with the breathing regulator has the problems of large breathing resistance and ideal application effect for ordinary people, but has extremely weak breathing function for partial critical patients, and cannot automatically overcome the breathing resistance to inhale oxygen. Therefore, the patients in this part can only be treated by oxygen inhalation in a normal flow oxygen mode, and the normal flow oxygen mode has two modes, one mode is an oxygen inhalation method by using a nasal obstruction and a nasal catheter, and the other mode is an oxygen inhalation method by using an oral-nasal mask. Nasal obstruction and nasal catheter oxygen inhalation cause serious problems of oxygen leakage and waste. The oral-nasal breathing mask can reduce oxygen leakage to a certain extent, but can generate breathing resistance at the same time, and currently, the breathing resistance is usually relieved by adopting an additional air bag, but the effect of practical clinical application is not ideal, and the cost and the complexity of the structure are increased. Obviously, the breathing mask is still not friendly to weak and difficult breathing patients.

In view of the above, it would be desirable and advantageous to provide an oxygen mask that is free of resistance.
