An anti-reflux valve prevents output from flowing back toward the stoma, reducing the risk of skin irritation and increasing user comfort, especially for those with liquid output or using high output pouches. Products like the 401558 and 401559 feature this valve, making them ideal for users who want added protection from backflow. The presence or absence of this feature gives users the flexibility to choose the pouch that best matches their health and comfort needs.
