At present, the closed sputum suction tube commonly used in clinical practice can solve the problems of interrupting ventilator treatment and airway exposure during suctioning, and prevent cross-infection, but there are still many deficiencies. First of all, there is a lack of devices to prevent aspiration. When medical staff use the existing closed sputum suction tube for sputum suction operation, on the one hand, when the sputum suction tube is flushed, since the rinsing fluid is connected to the airway, if the negative pressure suction cannot quickly remove all the rinsing fluid in time During suction, the flushing fluid may enter the patient's airway; on the other hand, after flushing the suction tube, once the medical staff forgets to close the valve of the flushing fluid, the flushing fluid will flow directly into the patient's air flushing tube connector. All of these conditions can cause the patient to choke, inhale, and, in severe cases, may cause the patient to suffocate. Secondly, there is a lack of devices for measuring sputum, most of the sputum is estimated by medical staff, and the accuracy of measurement cannot be guaranteed. The third medical staff cannot collect sputum samples through the existing closed sputum suction device.
