[0002] Sputum suction refers to a method of sucking sputum in the respiratory tract through the oral cavity, nasal cavity, artificial airway (cannula and tracheostomy) to keep the respiratory tract unobstructed, prevent aspiration pneumonia, atelectasis, asphyxia and other complications, and is particularly suitable for coma patients.

[0003] The existing sputum suction device needs medical staff to determine whether the patient has sputum blockage before sputum suction, and then the sputum suction device system is used. The whole process is basically operated by medical staff, and the labor intensity is large. In addition, the sputum suction tube of the sputum suction device is a flexible tube which can enter the airway through the oral cavity or nasal cavity to suck sputum. The sputum suction tube is a disposable product. The sputum suction tube after sucking sputum needs to be sterilized by manual operation and then treated. However, the bacteria in the residual sputum on the sputum suction tube may be transmitted to the medical staff, which is not conducive to the physical and mental health of the medical staff.
