摘要： A puncture needle cartridge 20 detachably mounted on a puncturing device body to form a puncturing device is provided with a needle body 21 having a puncturing portion 212a, and also with a casing 22 for housing the needle body 21 and having openings 223, 224 that are respectively formed in front of and behind the needle body 21. The needle body 21 is mounted so as to be movable between a retracted position, wherein the tip 212c of the puncturing portion is retraced in the casing 22, and an extended position, wherein the tip 212c of the puncturing portion is projected outward from the casing 22 by receiving a pressing force from the puncturing device body. The needle body 21 has a biasing means for biasing the needle body 21 from an extended position towards a retracted position. The puncture needle cartridge can be mass-produced at low cost, and enables a user to perform puncturing safely and easily.

摘要： A medical needle extending in a specified direction, wherein the cross sectional area of a vertical cross section cut by a plan perpendicular to the specified direction is regularly increased or decreased depending on a distance from the tip part thereof. The medial needle comprises a plurality of maximum points where the cross sectional area of the vertical cross section is maximized and a plurality of minimum points where the cross sectional area of the vertical cross section is minimized. The cross sectional area of the vertical cross section at the maximum point nearest the tip part is equal to or larger than the cross sectional area of the vertical cross section at the other maximum points. Thus, when the medial needle is pierced in a patient, pain given to the patient can be minimized and damage to the pierced portion of the patient can be minimized.
