Application:

1. Surgery: laparoscopic surgery, colorectal surgery

2. Critical care and infection prevention and control: critically ill neurological patients, central venous catheter maintenance

3. Gynecology and emergency: abortion surgery, impotence treatment

4. Scientific research and special scenarios: biological experiments, industrial applications

Feature:

1. Medical grade materials: platinum vulcanized silicone, biocompatibility certified, meets high temperature steam sterilization requirements

2. Negative pressure resistance: can withstand clinical negative pressure range (-0.02MPa to -0.1MPa), under certain conditions (such as 30s at 25°C), the tube wall does not collapse, ensuring smooth drainage

3. Structural and design optimization: double sleeve structure, anti-blocking design, intelligent pressure control system

4. Functional expansion and safety: constant temperature technology, anti-backflow mechanism
