[0035] More preferably, water is injected into the water gasket 102 through the liquid inlet terminal 105, and the mask body 1 is placed on the patient's face. The adsorption lip 101 located at the inner edge and the outer edge of the end of the mask body 1 fits with the patient's face, so that the mask body 1 is adsorbed on the patient's face as a whole, ensuring that the water gasket 102 and the patient's face are in contact with each other, which is more comfortable. By pressing down the two limiting strips 3 close to one end of the air inlet terminal 2, the first compression spring 4 is compressed, so that the two limiting strips 3 and the end of the air inlet pipe 201 are inserted into the patient's mouth. After the limiting strips 3 are released, the two limiting strips 3 are respectively abutted against the patient's upper jaw and lower jaw under the restoring action of the first compression spring 4, which assists the mask body 1 to be attached to the patient. The face is fixed and the displacement of the mask body 1 is effectively avoided. The sealing soft sleeve 205 located at one end of the air inlet terminal 2 and between the outside of the mask body 1 and the air inlet pipe 201 effectively seals the mask body 1 to prevent external air from entering. When the mask body 1 is adsorbed on the patient's face, the nasal mask 6 covers the patient's nose. Under the action of the second compression spring 7, the nasal mask 6 fits tightly against the patient's face, and the mask body 1 is separated from the nasal mask 6 to avoid mixing of inhaled and exhaled gases, which is helpful for the treatment of the patient. Under the action of the activated carbon filter plate 602, the gas exhaled by the patient is filtered to prevent the gas exhaled by patients with infectious respiratory diseases from polluting the surrounding environment and causing cross infection.
