Abstract | A catheter assembly (10) has: an inner needle (14) for puncturing a living body; a catheter (12) through which the inner needle (14) is inserted; a catheter hub (20) provided at the proximal end of the catheter (12); a valve body (24) provided in the inner space (50) of the catheter hub (20); a cylindrical body part (68); a neck part (70) having a reduced diameter and protruding from the body part (68); and a foot part (72) protruding on the proximal side of the body part (68). The catheter assembly (10) is provided with: an opening member (26) which is disposed on the proximal side of the valve body (24) and moves toward the distal end along the inner space (50) of the catheter hub (20) such that the valve body (24) is opened by the neck part (70); and a neck rib (73) for generating a resistance force acting against the movement of the opening member (26) toward the distal end.
L'invention concerne un ensemble cathéter (10) qui comprend : une aiguille interne (14) pour percer un corps vivant ; un cathéter (12) à travers lequel l'aiguille interne (14) est introduite ; une embase de cathéter (20) disposée au niveau de l'extrémité proximale du cathéter (12) ; un corps de valve (24) disposé dans l'espace interne (50) de l'embase de cathéter (20) ; une partie de corps cylindrique (68) ; une partie de col (70) ayant un diamètre réduit et faisant saillie à partir de la partie de corps (68) ; et une partie de pied (72) faisant saillie sur le côté proximal de la partie de corps (68). L'ensemble cathéter (10) comprend : un élément d'ouverture (26) qui est disposé sur le côté proximal du corps de valve (24) et se déplace vers l'extrémité distale le long de l'espace interne (50) de l'embase de cathéter (20) de telle sorte que le corps de valve (24) est ouvert par la partie de col (70) ; et une nervure de col (73) pour produire une force de résistance contre le mouvement de l'élément d'ouverture (26) vers l'extrémité distale.
カテーテル組立体(10)は、生体内に穿刺される内針(14)と、内針(14)が挿通されるカテーテル(12)と、カテーテル(12)の基端に設けられたカテーテルハブ(20)と、カテーテルハブ(20)の内部空間(50)に設けられる弁体(24)と、円筒状の胴部(68)と、胴部(68)の先端から縮径して延び出る首部(70)と、胴部(68)の基端側に延び出た足部(72)と、を有し、弁体(24)の基端側に配置され、カテーテルハブ(20)の内部空間(50)に沿って先端側に移動することで首部(70)により弁体(24)を開通させる開通部材(26)と、開通部材(26)の先端側への移動に抵抗力を発生する首リブ(73)を備える。 |
