A non-reflux valve prevents urine from flowing back toward the stoma, reducing the risk of infection and skin irritation. This feature is especially important for maintaining skin health and ensuring hygienic drainage. Both the Hollister 84590 and Hollister 8450 feature internal non-reflux valves, which are highly beneficial for long-term stoma care. There are products with and without non-reflux valves, so users can choose the level of protection they need.
