ABSTRACT:
A nasogastric (NG) tube provided with a normally-curved or normally-bent leading end. When passed, the normally-curved/bent leading end negotiates the nasopharynx with the tip of the NG tube biased to conform to the shape of the soft palate, thereby applying a reduced pressure against the posterior nasopharynx. After passing the nasopharynx, the normally-curved/bent leading end is rotated 180.degree. such that the tip is biased in a posterior direction such that it more reliably enters the esophagus. After entering the esophagus, the NG tube is rotated an additional 90.degree. such that when the tip of the NG tube enters the stomach, the tip is biased toward the stomach outlet. A second curved portion located near the normally-curved/bent leading end provides additional biasing force to help the tip enter the esophagus. A longitudinal line, stripe or other form of marking is placed on the tube to prompt the nurse/physician when to make the 180.degree. and 90.degree. rotations.
