<P>PROBLEM TO BE SOLVED: To provide a blood sending tube which can quickly and accurately send blood, and a blood feeding device using the blood sending tube, and in addition, to provide a blood sending tube which can be generally used for various kinds of operations regardless of the size, the age or the disease of a patient (subject), and a blood feeding device using this blood sending tube. <P>SOLUTION: This blood sending tube has a plurality of branched passages 3 which are branched and formed by a branching means 2, and comprises the branched passage 3 the inner diameter of which is made equal to or smaller than the inner diameter of one trunk flow passage 1 as a maximum every time when being branched. Then, a plurality of branched flow passages each partitioning ratio of which for pressure or a flow rate is determined are formed by a combination of the branched passages 3 having respective peculiar inner diameters and tube lengths. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
