When a patient generates phlegm sound or breathes difficultly and is difficult to actively discharge because a respiratory tract generates more sputum, the sputum of the respiratory tract needs to be sucked by the patient, and when the sputum is sucked, the sputum of the respiratory tract needs to be sucked by the sputum suction pipe through an oral cavity, a nasal cavity or an artificial airway. When the sputum is sucked, the sputum suction pipe is connected with a sputum aspirator, and the sputum can be sucked out through negative pressure formed by the sputum aspirator.

When the patient is an infant or a newborn, the respiratory tract of the infant and the newborn is fragile, and the respiratory tract of the infant and the newborn is easily damaged when the operation is improper or the sputum suction time exceeds a set time.
