24h Closed Suction Catheters-Clinical Practice
* Hospital: economic, no need to stop machine, saving hospital's cost.
* Nurse: improving mechanical ventilation's effectiveness, improving airway management quality and successful rescue rate, and
lessening the workload of doctors and nurses.
* patient: decreasing the possibility of airway infection, lessening complication, improving patient's life quality, preventing
relative pneumonia of respiratory machines.

72h Closed Suction Catheters-Clinical Practice
* Improving sputum suction effectiveness.
* Lessening nurse's workload.
* Avoid pollution and cross infection.
* No need to terminate ventilation, not influencing airway pressure.
* Complete tightness, protecting the safety of patients, doctors and nurses.
* Easy to operate, convenient, saving time and money, satisfying patient's need in time.
Closed suction system consists of a three-way valve, a adapter and a suction catheter. The suction catheter extends from the three-way valve to the adapter and is covered in thin film. The three-way valve has distilled water delivery port for cleaning after use. When in use, the three-way valve connects to an Endotracheal tube or Tracheostomy through patient port and a ventilator through the breathing port. Adapter button activates suctioning and suction catheter can be inserted or retracted through the three-way valve into patients airway. The catheter is graduated for easy identification of depth of insertion.
