Urocare is the sole manufacturer of reusable latex leg bags, disposable vinyl leg bags and urinary drainage systems that incorporate the full advantages of our famous, patented high-flow anti-reflux valve (#6001). This remarkable anti-reflux valve is enclosed in a hard plastic housing which prevents the valve from being accidentally held closed when in sitting or reclining positions. The valve is virtually self-cleaning and interference free ensuring fast, uninterrupted flow and problem-free use. Don't settle for urine reflux or back-pressure caused by inferior flutter valves. Nothing beats Urocare's new high-flow Little Red Valve for performance, reliability and safety. We don't give odor a chance! We added a special new odor control barrier to the inside & outside of our latex leg bags for double odor protection. This special odor barrier makes Urocare's leg bags virtually ODOR-FREE, not just odor-resistant; thereby preventing embarrassing odors before they start.
