Ideal for home care use, the anti-reflux valve on this drain bag helps prevent urine reflux. All drain bags have a reinforced hanger with built-in anti-kink drain tube guide and adjustable bed sheet clam. The anti-reflux tower provides anti-reflux protection without mechanical parts to hinder flow. The anti-reflux device has a clear one-way mylar valve for visualization of urine flow. The anti-reflux valve flap system minimizes back flow into the drainage tube.
