Cantor tube [Meyer O. Cantor, American physician, b. 1907] , a long, single-lumen nasoenteric tube with a small, sealed, mercury-filled rubber bag at the distal end, used to relieve obstructions in the small intestine. The tube also contains drainage holes to allow for aspiration of intestinal contents. Now largely replaced by the Andersen long weighted sump tube due to concerns related to potential failure of the mercury weighted bag.
