ABSTRACT:
A naso-gastric tube has a large bore through which gas and liquid can be removed from the stomach and oesophagus, and a small bore through which liquid can be introduced to the duodenum. The large bore is closed at one end of the tube whereas the small bore opens at this end. The tube has a region of several apertures through which the large bore opens from the tube; the region is spaced from the end of the tube by a first distance of at least 10 cm, the region extending for a second distance approximately equal to the first distance. In this way, when the open end of the small bore is located in the duodenum, the apertures will be located in the lower oesophagus and the upper part of the stomach.
