1. Medical grade silicone material, good biocompatibility;
2. The cuff fits tightly to improve product safety;
3. Fence design prevents foreign objects from flowing back and blocking the passage;
4. After the cuff is inflated, the force is balanced, and the junction with the tube body is smoothly transitioned, without obvious bumps, and reduces body damage;
5. The independent drainage hole on the top of the cuff facilitates various drainage operations and effectively isolates the airway from the esophagus.
