Background

The closed sputum suction tube is a medical auxiliary article commonly used after operation, and is commonly used for cleaning respiratory sputum of severe patients, postoperative patients and patients with weak and weak sputum to keep the respiratory tract smooth. The sputum suction tube which is commonly used in clinic is a disposable smooth suction tube, and a membrane sleeve is arranged on the suction tube of the suction tube.

The sputum suction tube used at present comprises a patient end, a suction tube, a membrane sleeve and a negative pressure end, wherein the negative pressure end is connected with a negative pressure instrument, the patient end is inserted into a patient airway interface and a respirator interface, the membrane sleeve is connected with the patient end and the negative pressure end, and the suction tube is positioned in the membrane sleeve. When in use, the suction tube moves towards the tracheal cannula at the patient end, and the membrane sleeve forms folds in the process; and straightening the membrane sleeve after the pipe drawing and inserting are completed. The sputum suction tube is repeatedly used according to the mode to finish sputum extraction.

The incidence rate of the clinical closed sputum suction is obviously lower than that of the clinical open sputum suction. The closed sputum suction is applied to the sputum suction process, so that the air passage tightness is guaranteed, the inhalation of bacterium-containing aerosol in the air is obviously reduced, the inadvertent pollution caused by the use of open sputum suction is avoided, the chance of exogenous infection is reduced, and a common infusion apparatus is connected with a sodium chloride solution for flushing a tube after the closed sputum suction is applied clinically. Although convenient to use, the flushing fluid still has misoperation, so that a large amount of sodium chloride enters the airway of a patient, and the severe suffocation risk is caused. And the direct-flow water flow is used, the sputum attached to the suction pipe wall cannot be completely washed away, and the long-time retention of the sputum can lead to the propagation of the planting bacteria and aggravate infection.

But still use the straight-flow rivers, the sputum can't be washed out completely, and uncontrollable flush fluid input volume needs frequently to change the reservoir, both consumes medical personnel too much labour, increases the risk of patient's respiratory tract pollution again.

The prior art has the following defects:

firstly, no flushing device specially used for a closed sputum suction tube exists at present, and a common infusion apparatus is used for replacing a flushing tube device, so that a large amount of flushing liquid enters an airway due to errors, and serious risk of asphyxia is caused.

Secondly, the transfusion system replaces a tube flushing device to use direct-flow water flow, sputum attached to the tube drawing wall cannot be completely flushed, and long-time retention of the sputum can lead to reproduction of planting bacteria and aggravate infection.

Thirdly, the infusion apparatus replaces a washing pipe device, the injection amount of the washing liquid cannot be controlled, and the injection amount of the washing liquid is too small, so that the inner wall of the suction pipe and the oral cavity of a patient cannot be washed cleanly; the flush fluid injection volume is too much, needs frequently to change the reservoir, both consumes medical personnel's too much labour, increases the risk that patient's respiratory tract pollutes again.
