する腸管内挿入用カテーテル。 A tube body comprising a guide portion consisting of a flexible tube with a plurality of weights embedded in a bead shape at its tip portion, a fluid-expandable balloon, and a plurality of suction holes provided on the front and rear tube surfaces of the balloon, and a balloon. A catheter structure in which a sub-lumen for inflating the tube is installed on the side wall of the tube body, and the sub-lumen and the main lumen of the tube body are connected to a thin tube having a connector attached at the proximal end. A small hole communicating with the main lumen sealed by a tip member is bored, and the size of the suction hole is set to be located on the rear end side of the balloon with respect to the diameter of the first hole located on the distal side of the balloon. A catheter for insertion into the intestinal tract, characterized in that the diameter of the second hole is the same or smaller, and the diameters of the third and subsequent holes installed on the rear end side of the second hole are smaller than those of the first hole.
