ABSTRACT:
An enema administering apparatus insertable into the rectum for delivery of a contrast medium to internal portions of a patient's anatomy includes an enema tip wherein the enema tip has a contrast medium passageway extending therethrough and is able to be coupled through the use of a disclosed adapter to a source of contrast medium. Also disclosed in various arrangements is 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 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. Also disclosed are air valve means that close the air passageway to the flow of barium in one direction yet open for the flow of air in the opposite direction.
