Abstract
A method and device for obtaining the type of gastric mucosal coating of a human being's upper gastrointestinal tract to enable a double-contrast study of said tract to be performed are disclosed. The method comprises the steps of providing an open-ended feed tube having first and second ends, and having a vent in the feed tube for the introduction of ambient air. The vent comprises venting means which are disposed in a direction towards the second end of the feed tube. The first end of the feed tube is disposed into a supply of contrast medium and the medium is ingested by sucking from the second end of the feed tube while simultaneously ingesting air through the venting means. The venting means define a vent opening which is large enough to permit ingestion of a sufficient amount of air to effect a desired degree of distention of the organs in the tract and small enough to prevent interference with the ingestion of the contrast medium, whereby the gaseous distention enhances the gastric mucosal coating and enables a double-contrast study of the organs to be performed.
