These tubes are made from polyurethane (PU) to ensure their flexibility is not affected by temperature and to have a long lifespan. The tubes are smooth and easy to pass. The tapered tip with rounded edges reduces the risk of tissue damage. Meanwhile, the other end is designed in a zigzag shape to secure and facilitate connection with both the stomach pump, funnel, and activated charcoal bottle. Easy to clean and capable of withstanding all common disinfectants. Contains painless side openings (2).
