Abstract
A reflux indicating device for a urine collection bag which has a chamber for collecting urine from a patient. A receiving conduit is in communication with the drain tube on a catheter to empty urine into the chamber. An annular channel is secured into the upper distal most end of the receiving conduit. If the bag is laid on one of its sides, urine will get trapped in the channel and alert medical personnel of possible retrograde contamination of the drain tube and catheter by bacteria contained within any urine already in the chamber.
