[0002] An artificial nose is a professional product that can temporarily replace the nose. Its main functions are to filter the air, maintain the body's acid-base balance, and maintain stable air pressure in the body. It can also warm and humidify, as well as clean foreign matter. It can improve lung function and reduce the incidence of lung infections.

[0003] For patients who cannot breathe independently, an artificial nose needs to be installed in series in the ventilator pipeline, such as the artificial nose disclosed in CN201520067285.0; for patients who can breathe independently, the artificial nose can be installed at the end of the pipeline, such as the artificial nose ventilator heat and moisture extension device disclosed in CN202320526711.7.
