<P>PROBLEM TO BE SOLVED: To make it possible to easily insert a puncture needle into a blood vessel with weaker force during puncturing of second time or after. <P>SOLUTION: A puncturing needle 1 has an inclined end face 20 at the distal end of the needle and a puncturing opening 101a radially opening and tearing to a proximal side from the start point of a deep side to a puncturing direction is formed in the surface of the blood vessel by puncturing with the inclined end face 20 directed downward. The inclined end face 20 is inclined to the central axis A of the puncturing needle, a pointed end part 21 is formed in the distal end of the inclined end face 20, and the pointed end part 21 is curved to the central axis A side of the needle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
