[0002] A breathing mask is an auxiliary tool that allows breathing through the nose and mouth. It is mainly used to help patients improve ventilation and relieve their hypoxia symptoms. When using a breathing mask, patients need to be careful not to use excessive force to prevent the mask from falling off, which may also cause the patient to choke and cough. At the same time, when using a breathing mask, patients also need to pay attention to keeping the airway open to avoid breathing difficulties. When patients are undergoing gas anesthesia treatment, they breathe anesthetic gas through a mask.

[0003] Existing anesthesia breathing masks are usually connected to breathing tubes. When a damaged mask needs to be replaced, it is troublesome and cannot be disassembled quickly. At the same time, some patients cough during anesthesia breathing, and bacteria will adhere to the mask, requiring high-temperature disinfection. Usually, the mask is removed and placed in a high-temperature disinfection cabinet for disinfection, which is very troublesome. Therefore, an anesthesia mask device that is easy to replace is required. Summary of the invention
