摘要

An enema administering apparatus (20) insertable into the rectum for delivery of a contrast medium to internal portions of a patient's anatomy includes an enema tube (21) joined to an enema tip (22) wherein the enema tube and enema tip have a common contrast medium passageway (25) extending therethrough and an air passageway (24) 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. Air introduction means and contrast medium introduction means are provided by various arrangements suitable for use with the main enema administering apparatus concept disclosed.
