TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, concretely is a closed sputum suction tube. BACKGROUND

[0002] In the traditional field, sputum suction is a common operation in nursing when coma patients are hospitalized and respiratory tract sputum secretion is too much and too sticky, and the purpose is to remove the secretions in the respiratory tract and keep the respiratory tract unobstructed. In clinical practice, a sputum suction tube and a negative pressure suction tube are usually connected, the sputum suction tube is inserted into the respiratory tract of the patient, and sputum suction operation is performed by using negative pressure. When the medical staff performs sputum suction operation on the patient by using the ordinary sputum suction tube, the sputum suction tube and the air are in contact, which increases the harm of harmful microorganisms in the air to the patient; at the same time, it also increases the harm of bacteria in sputum to the medical staff. In the prior art, the gas cutting atomizer cannot be connected with the closed sputum suction tube, which leads to aerosol splashing caused by open sputum suction for patients with multiple drug-resistant bacteria, and increases the infection rate of MDR patients.

[0003] For example, the authorized patent document with the application number CN202020661125.X discloses a closed sputum suction tube, which comprises a shell, a rotating part and a tube body.

The tube body surrounds the outer surface of the mounting part. By rotating the rotating part, the rotating part drives the tube body to rotate, so that one end of the tube body enters the tracheal cannula from the shell through the insertion hole to clean the respiratory tract sputum of the patient. After the patient finishes sputum suction, the rotating part is rotated to make one end of the tube body retract from the tracheal cannula to the shell and surround the rotating part. Compared with the commonly used sputum suction tube, the closed sputum suction tube can insert one end of the tube body into the tracheal cannula at a suitable position by rotating the rotating part, which is convenient to use and has high intubation efficiency. Moreover, external force does not need to be applied to the shell to assist intubation, which avoids air leakage caused by shell damage and prolongs the service life.
