A reflux valve prevents urine from flowing back toward the stoma, reducing irritation and the risk of infection. This feature offers peace of mind, especially for overnight use or when connecting to a night bag. The non-return reflux valve is included in products such as the Marlen 72622 and Marlen 72690, ensuring added protection against backflow. All Marlen UltraMax pouches in this category offer this feature, so you can choose the size and style that fits you best while maintaining this essential benefit.
