The Belly Bag Collection Device is worn at the waist and is designed for either males or females who have an indwelling catheter. The bag fastens around the waist by means of a woven belt with a quick release buckle. It has a 1000 mL capacity and is not made with natural rubber latex. An anti-reflux valve behind the catheter port prevents reflux urine flow. The Belly Bag is emptied by means of a drain tube with a twist valve that is in the approximate position of the urethra. Users can easily sleep with the bag in place, thus it can be worn 24 hours a day.
