医疗用针及医疗用设备
摘要：
本发明的医疗用针，沿规定方向延伸，用与该方向垂直的平面进行剖切得到的垂直截面的截面积随着到前端部的距离不同而规律性地增减。另外，该医疗用针具有垂直截面的截面积达到极大的多个极大点、以及垂直截面的截面积达到极小的多个极小点，最靠近前端部的极大点处的垂直截面的截面积与其他各极大点处的垂直截面的截面积相同或比它们大。因此，采用本发明的话，则在将该医疗用针向患者刺入时，可尽量减小带给患者的痛楚，极力抑制患者的刺入部位的损伤。
摘要（英）：

A medical needle extending in a specified direction, wherein the cross sectional area of a vertical cross section cut by a plane 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.
