SNAA030 Suction tube 13cm interchangeable φ1.5/2/2.5/3/4 1. Suction of fluid and blood: The suction tube draws fluid and blood from the surgical area into the tube through the principle of negative pressure. This helps to keep the surgical area clean and dry, providing a better view and operating environment. 2. Drainage of tissue debris: Tissue debris, foreign bodies or other unwanted materials may be generated during surgery. The suction tube draws these substances into the tube to ensure a clean and unobstructed surgical area. 3. Maintaining an open airway: Suction tubes can also be used to maintain an open airway for the patient during certain procedures. By attracting secretions and discharges from the mouth and throat, suction tubes can prevent airway obstruction and choking from occurring. 4. Reducing the risk of infection: The suction tube can effectively remove blood and body fluids from the surgical area, reducing the risk of infection. It helps the surgeon to keep the surgical area clean and prevents infectious substances from entering the patient's body. 5. Provide operational convenience: Suction tubes are usually soft and easily bendable, which can be adapted to the needs of different surgical scenarios. Doctors can adjust the shape and position of the suction tube as needed to better complete the surgical operation.
