ABSTRACT:
A nasogastric catheter comprises a tube of relatively flexible material defining a main duct extending from one end of the tube to the other end thereof, and first and second inflatable vessels which are mounted at the exterior of the tube and through which the tube extends. The vessels are situated along the tube approximately three-quarters of the way along the tube from the one end to the other end and are spaced from one another along the tube. First and second subsidiary conduits extend within the tube from the one end and communicate with the first and second vessels respectively but are isolated from said main duct. The tube is formed with at least one lateral perforation between the first and second vessels and a plurality of lateral perforations after the second vessel, the lateral perforations establishing communication between the main duct and the exterior of the tube.
