Abstract
(EN)
Provided is an indwelling needle assembly having a novel structure, which can open, without providing a special member in an outer needle hub, a slit of an elastic valve body when a male connector is connected. In an indwelling needle assembly 10 in which an inner needle 18 is inserted through an elastic valve body 78 having a slit 82 mounted on an outer needle hub 22, an inner locking claw 52 and an outer locking claw 68 provided at a proximal end of the outer needle hub 22 are locked by an inner locking groove 88 and an outer locking groove 90 formed in an outer peripheral portion of the elastic valve body 78, and the elastic valve body 78 is radially compressed by at least one among the inner locking claw 52 and the outer locking claw 68.

L'invention concerne un ensemble aiguille à demeure ayant une nouvelle structure, qui peut ouvrir, sans avoir à fournir un élément spécial dans une embase d'aiguille externe, une fente d'un corps de valve élastique lorsqu'un connecteur mâle est connecté. Dans un ensemble aiguille à demeure (10) dans lequel une aiguille interne (18) est insérée à travers un corps de valve élastique (78) ayant une fente (82) montée sur une embase d'aiguille externe (22), une griffe de verrouillage interne (52) et une griffe de verrouillage externe (68) disposées au niveau d'une extrémité proximale de l'embase d'aiguille externe (22) sont verrouillées par une rainure de verrouillage interne (88) et une rainure de verrouillage externe (90) formées dans une partie périphérique externe du corps de valve élastique, lequel est radialement comprimé par au moins l'une des griffes parmi la griffe de verrouillage interne (52) et la griffe de verrouillage externe (68).
