Bard leg bags are durable pouches used along with an external catheter or foley catheter to collect and contain urine. Catheter tubing allows urine to flow from the end of the catheter to the opening of the leg bag. The urinary drainage bag is made of heavy duty vinyl that allows for extended wear and prevents leaks. Your drainage bag can be secured using adjustable straps or a spandex fabric sleeve. Many of the Bard leg bags we sell include a leg bag holder or straps, but you can also buy them separately. Your leg bag can be worn around the thigh or calf to suit your preference. Every Bard leg bag has an anti-reflux valve to stop urine from flowing back up the tubing. These catheter leg bags are available with or without a drainage valve, which open and close with a simple flip.
