The Cardinal Health Flatus Bag and Rectal Tube was created for the relief of flatus symptoms by means of an enema aid. Flatus is when gas has formed in the intestines or stomach and causes a bloated feeling. Many things can cause flatus, from swallowing of air or eating foods such as onions and garlic or high-fiber foods. This item is used by doctors, physicians, and sometimes by patients in-home. This flatus bag and 24 French, 19-inch-long rectal tube package works by holding the flatus gas as it is being expelled from within your body. The bag serves to collect the gas as well as conceal any fecal matter that may also be expunged from the intestine.
