Abstract
(EN)
[Problem] The purpose of the present invention is to provide a medical elongated body having further enhanced ability to follow a meandering blood vessel, and a puncture needle assembly provided with the medical elongated body. [Solution] A medical elongated body 100 is provided with: a catheter main body 110 which is transdermally inserted into a blood vessel B; and a catheter hub 130 positioned proximal to the catheter main body. The catheter main body has a lumen 115, a distally positioned first region 111A, and a second region 113A positioned proximal to the first region. The first region has a bending part 120 which bends relative to the central axis C2 of the second region in the longitudinal direction. The second region is connected to the catheter hub such that the catheter main body can rotate relative to the catheter hub.

[Problème] Le but de la présente invention est de fournir un corps allongé médical présentant une aptitude davantage améliorée à suivre un vaisseau sanguin sinueux, et un ensemble aiguille de ponction pourvu du corps allongé médical. [Solution] Un corps allongé médical 100 est pourvu : d'un corps principal de cathéter 110 qui est inséré par voie transdermique dans un vaisseau sanguin B ; et d'un raccord de cathéter 130 positionné à proximité du corps principal de cathéter. Le corps principal de cathéter présente une lumière 115, une première région 111A positionnée de façon distale et une deuxième région 113A positionnée à proximité de la première région. La première région présente une partie de courbure 120 qui se courbe par rapport à l'axe central C2 de la deuxième région dans la direction longitudinale. La deuxième région est reliée au raccord de cathéter de telle sorte que le corps principal de cathéter peut tourner par rapport au raccord de cathéter.
