Patients with a tracheotomy cannot breathe through the nose. In order to maintain their vital signs, a tracheal tube is usually inserted into the patient's throat for the patient to breathe. However, the artificial airway does not have the natural respiratory system to humidify the inhaled air. Due to the insufficient humidification function of the artificial airway, phlegm scab will form in the patient's upper respiratory tract, which will block the bronchi, cause breathing difficulties or even suffocation, and the rate of lung infection will also increase. Therefore, when using an artificial airway, help the patient to humidify the airway Very important. Sometimes, painless, rapid and effective treatment can also be achieved through respiratory administration.

However, the current technology usually requires the nursing staff to manually humidify the water droplets or administer medicines, which requires the nursing staff to strengthen inspections, which increases the labor intensity and nursing difficulty of the nursing staff.
