Abstract

La présente invention concerne une aiguille d'injection médicale et son procédé de fabrication. L'aiguille d'injection médicale de la présente invention est caractérisée en ce que l'intérieur, constitué d'un matériau métallique, est formé comme un tube cylindrique creux; au niveau d'une extrémité du tube, une partie de coupe (10) constituée d'une partie inclinée (11) et d'une partie horizontale (12) est formée, la partie inclinée étant inclinée vers le bas selon un certain angle à partir de l'extrémité supérieure sur le côté et ayant une extrémité inférieure positionnée plus bas que l'axe central (a) du tube, et la partie horizontale étant reliée à l'extrémité avant de la partie inclinée (11) et étant formée parallèlement à l'axe central (a) du tube; au niveau d'une extrémité du tube, une partie ronde et plate (20) ayant une forme arrondie de manière convexe sur le plan est formée; et la forme de la surface de section transversale latérale de la partie horizontale (12) est constituée d'une partie faisant saillie (14) et d'une partie arrondie latérale (16), la partie faisant saillie présentant une extrémité avant reliée à l'extrémité avant de la surface circonférentielle interne inférieure (13) du tube, étant formée verticalement vers le haut à partir de l'extrémité avant de la surface circonférentielle interne inférieure (13) du tube, et ayant l'autre extrémité avant reliée à la partie horizontale (12); et la partie latérale arrondie possédant un côté relié à l'extrémité avant de la partie horizontale (12) et ayant l'autre côté relié avec la surface inférieure (15) du tube tout en formant une courbe vers le bas. Selon la présente invention, l'extrémité de l'aiguille d'injection a une forme arrondie lorsqu'elle est vue dans le plan et a une forme arrondie dans la direction vers le haut depuis le fond lorsqu'elle est vue depuis le côté, et ainsi aucune partie pointue n'est formée et, de ce fait, les blessures des muscles, des nerfs et des vaisseaux sanguins ne se produisent pas lorsqu'elle est insérée sous la peau. En raison de la formation de la partie de coupe constituée de la partie inclinée, inclinée selon un certain angle à partir d'un côté de la section supérieure lorsqu'elle est vue depuis le côté, et de la partie horizontale parallèlement à la direction de l'axe central, un fil peut être introduit sans à-coup tout en étant naturellement suspendu dans la partie de coupe pendant l'injection sous la peau tandis qu'une partie du fil est inséré. En particulier, en raison de la formation de la fine protubérance au niveau de l'extrémité de l'aiguille d'injection, même si le fil n'est pas un fil prévu avec une partie torsadée, le fil est naturellement torsadé, plié et inséré au cours de l'insertion de l'aiguille d'injection sous la peau, permettant ainsi une intervention chirurgicale exacte. En outre, l'aiguille d'injection est fabriquée par un procédé de finition par ponçage suivant un procédé de coupe de la partie coupe après que l'extrémité d'un tube creux soit soudée tandis qu'une tige est placée sur celui-ci, et, de ce fait, le fil est naturellement suspendu tandis que la surface circonférentielle interne de l'aiguille d'injection devient lisse.
