ABSTRACT:
The oral-nasal gastric tube includes three side-by-side passages disposed within a single tube. Two of the tubes branch outwardly from the main tube at one end to facilitate the attachment of one of the tubes to a suction attachment and a pressurized air source respectively. The third tube can be left open to the atmosphere to act as a pressure equalizer or can be utilized for the introduction of medicine or medical devices. The tube attached to the suction attachment and the pressure equalizer tube each terminate in a plurality of apertures adjacent the end of the main tube for supplying air to the body cavity as fluids are being drawn out through the suction tube. The tube attached to the pressurized air source terminates in a balloon which extends about the periphery of the main tube at a point spaced from the end of the main tube above the perforations.
