<P>PROBLEM TO BE SOLVED: To provide a medical tube which permits its insertability to be improved. <P>SOLUTION: The medical tube 10 includes a tube body 11, an inductor 16, a peristalsis balloon 17, and an induction balloon 20. The tube body 11 includes a main cavity 11d extending from a base portion 11a to a suction side hole 11c, and subsidiary cavities 11e, 11f, and 11g extending from the base side 11a to the tip side. The inductor 16 is provided with a through hole communicating with the subsidiary cavity 11g to allow the induction balloon 20 to expand at the tip of the inductor 16 by feeding air through the subsidiary cavity 11g and the through hole. The peristalsis balloon 17 can be expanded by feeding water through the subsidiary cavity 11f. The induction balloon 20 includes a baglike expansion and contraction portion 21 connecting the base portion to the tip side periphery of the inductor 16, and a supporting rod 22 movably installed in the through hole of the inductor 16 and connecting the tip portion to the inside tip of the expansion and contraction portion 21 and having flexibility. <P>COPYRIGHT: (C)2009,JPO&INPIT |
