title: A disposable barium and air rectal tip.
abstract: To prevent leakage during the barium enemas the retention balloon is maintained in close apposition to the anorectal junction. This has been accomplished by using the counterpressure produced by simply allowing barium to flow into a small bag on the rectal tip adjacent to the anus.
