Model Number: NH-08474


  1. It can achieve continual oxygen supply without separation of artificial circuits.
  2. The multiple-use plastic packing of suction catheter can avoid the infection caused by outside pathogens.
  3. When sputum suction tube left artificial airway, the gas flow of respirator will not be influenced.
  4. Closed suction catheter could both alleviate the complications and decrease oxygen partial pressure caused by suction, which effectively avoid cross infection.


Closed suction catheters can solve the following problems, such as interruption of ventilator treatment, cross infection and environmental pollution.

Advantages of a Closed Suction Catheter:

  1. It does not need to be separated from the artificial respiration circuit for sustainable oxygen supply.
  2. The repeatedly used sputum suction tube is wrapped with a plastic sleeve to avoid contact with the outside world.
  3. After sputum suction, the sputum suction tube leaves the artificial airway and will not interfere with the gas flow of the ventilator.
  4. Closed sputum suction tube can significantly reduce the complications caused by sputum suction, avoid the decrease of oxygen partial pressure caused by repeated off-line sputum suction, and effectively avoid cross infection.
  5. Improve the work efficiency of nurses. Compared with the open sputum suction, the closed type reduces the operations of opening the disposable sputum suction tube and disconnecting the ventilator, simplifies the sputum suction process, saves time and manpower compared with the open sputum suction, improves the work efficiency of nurses, and can respond to the needs of patients in time. After studying 149 closed suction and 127 open suction in 35 patients living in ICU after trauma, it is reported that the average time of closed suction in the whole process of each operation is 93s, while that of open suction is 153S.
