ABSTRACT An enema administering apparatus insertable into the rectum for delivery of a contrast medium to internal portions of a patient's anatomy. The device includes an enema tube joined to an enema tip wherein the enema tube and enema tip have a com- mon contrast medium passageway extending therethrough and an air passageway which is exterior of the contrast medium passageway and is able to be coupled to a source of air for double contrast studies. The air passageway may be a passageway disposed within the enema tube and enema tip construction or may be a separate tubing member joined therewith in a suitable arrangement to introduce air for the double contrast studies once the barium has been evacuated from the patient. The tube has a free end, an insertable end and a contrast medium passageway extending there- through from an inject location adjacent said free end to a dis- charge location adjacent said insertable end. An enlarged tip portion is situated at the insertable end of the tubular stem portion and has at least one contrast medium exit aperture located therein. The air passageway which is situated externally of the contrast medium passageway has an air delivery outlet opening at a location adjacent the contrast medium exit aperture.
