Background
The breathing machine is a medical device which can send oxygen-containing air into the lung, discharge carbon dioxide-containing gas out of the body and help the respiratory system to complete ventilation, and mainly comprises a step of directly applying pressure on the opening of the respiratory tract, wherein the gas is pressurized and pressed into alveoli during inspiration, and the gas is passively recovered along with the chest and the lung during expiration and is discharged out of the body. The manner of switching from inhalation to exhalation according to respiration can be classified into three types, pressure switching, capacity switching, and time switching. Breathing machines in modern medicine are commonly used for respiratory failure, anesthesia during operation, respiratory management, respiratory support treatment and emergency resuscitation caused by various reasons and occupy very important positions in the medical field, but the existing breathing machines have complex structures and large volumes and cannot be used on the premise of not moving patients; in addition, for patients suffering from serious respiratory diseases, the expired dirty gas contains a large amount of germs, which easily causes cross infection among patients and medical staff; in addition, when the respiratory equipment is used for patients with infectious diseases, if the equipment is not effectively disinfected and cleaned, cross infection among patients is easy to occur.

However, when such devices are in use, the supplied oxygen is not humidified, and because the ventilator treatment involves the flow of air pressure through the nasal passages, which are often difficult to maintain warm and humid, the nasal passages are blood vessels and thus more prone to drying out by cold air, sometimes when the ventilator is in sleep, air may be inadvertently directed from the mouth to the nasal passages without reaching the lungs first, and this flow is cold, thus drying the nasal passages, possibly causing inflammation to the patient, leading to bleeding of the nose, dry mouth, broken lips, and dry nose.
