<P>PROBLEM TO BE SOLVED: To provide a medical tube or the like that is thin, flexible and excellent in both kink resistance and tensile strength. <P>SOLUTION: Three layers (11, 12, 13) of a shaft tube 19 are such that two adjacent layers form a double layer and move relative to the remaining layer. When the load required for one of the moving layers to move relative to the other layer is a first load and the load required to rupture the single layer or the double layer located on the side separated from a suction lumen 15 across an interface where the layers move relative to each other is a second load, the second load is greater than the first load. <P>COPYRIGHT: (C)2012,JPO&INPIT |
