When some patients with respiratory disorders are clinically nursed, mechanical ventilation equipment such as a breathing machine and the like is needed, and in order to further ensure smooth ventilation of the patients, secretion such as sputum and the like in the artificial airway needs to be regularly cleaned. At present, the widely used sputum aspirator is a closed sputum aspirator tube, and has the advantages that a gas conduit and a respirator pipeline do not need to be separated during sputum aspiration, so that cross infection is prevented while an airway is kept smooth. However, the sputum aspirating tube adopts a three-way joint, and after medical care personnel use an infusion apparatus to connect flushing fluid to flush sputum on the wall of the closed sputum aspirating tube, once forgetting to close an infusion valve, normal saline can directly flow into the trachea of a patient to cause the patient to choke, so that serious complicated infection, such as aspiration pneumonia, can cause the patient to suffocate.
When the closed sputum suction tube in the prior art is adopted, after sputum suction is completed for a patient, a link of cleaning the sputum suction tube is entered, and the cleaning process is as follows: firstly, pressing a negative pressure button of a negative pressure button; and secondly, opening a switch of the Murphy dropper. At the moment, the normal saline is sucked into the sputum suction tube by the negative pressure device for cleaning; thirdly, closing a Murphy's dropper switch; and fourthly, releasing the negative pressure button of the negative pressure button.
However, in the process of operating and cleaning the sputum suction tube, once the nurse forgets to operate the third step (i.e. forgets to turn off the Murphy's dropper switch), the nurse directly proceeds the fourth step (i.e. releases the negative pressure button), and then the normal saline can be directly filled into the lung (air duct) of the patient through the Murphy's dropper, so that the patient is choked, and further serious complicated infection, such as aspiration pneumonia, can cause suffocation of the patient in the serious patient. Therefore, it is necessary and urgent to design a safer closed sputum aspirator tube flushing device.
