1. The smart design of the Closed Suction Catheters allows the patients' breath-mechanical ventilation and suctioning simutaneously. 2. Push switch and Luer lock. This design can keep breathing and isolate the turbulent cleaning chamber, and prevent spray back, which reduces the risk of VAP (ventilator-associated pneumonia) for ventilated patients. 

3. Prevent cross infection. The closed suction systems are designed with protective sleeve to isolate the germs inside the patients and help caregivers avoid cross infection. 

4. Soft and smooth blue suction tip. This design reduces damage to mucous membranes. 

5. "Y" Adapter match different sizes of endotracheal tubes. The catheters are marked with accurate depth to understand the proper catheter insertion in the trachea. 

6. Available for tracheostomy tubes. The suction catheters match tracheostomy tubes, of which different lengths are available. The catheters are marked with accurate depth to understand the proper catheter insertion in the trachea. 

7. The design of push switch and Luer lock can reduce the risk of VAP for ventilated patients. 

8. "Y" Adapter sizes available, #2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0
