A rectal device and a method of inserting same. The tube has a resilient diaphragm connected thereto and extending transversely therefrom to block escape of the liquid being introduced. The diaphragm comprises a stiff outer ring and a more pliable central portion, the latter preferably including stiffening means in the form of ribs, fins or the like. For insertion, the diaphragm is wrapped around the tube and placed in an inserter tube having a rounded expandable distal end. After the whole assembly is inserted, the inserter tube is removed by sliding it down over the rectal device. The rectal device may comprise relatively movable inside an outer tubes with struts connecting the diaphragm to the distal end of the inside tube. After procedure is completed, whether using barium or cleansing enema, the diaphragm is then removed by slowly but firmly pulling on the removal cord. The diaphragm folds itself around the infusion tube for easy removal.
