An anti-reflux valve prevents urine from flowing back toward the skin or up the tubing, reducing the risk of infection and skin irritation. This feature is particularly important for long-term wear and for users with limited mobility. Both the Hollister 9349 and Hollister 9348 include integral anti-reflux valves, ensuring reliable one-way flow and enhanced user safety across product sizes.
