Abstract

La présente invention concerne un ensemble d'étanchéité modulaire, comprenant un joint d'étanchéité d'extrémité (1) et une valve antiretour (2), le joint d'étanchéité d'extrémité (1) et la valve antiretour (2) étant dans un raccordement d'accouplement concave-convexe l'un avec l'autre par l'intermédiaire d'un trou de raccordement (13-1) sur une ailette de raccordement (13) et un crochet de raccordement (23) sur la valve antiretour (2). Une fente de positionnement (24) sur la valve antiretour (2) présente une fonction de guidage, facilitant le glissement du crochet de raccordement (23) dans le trou de raccordement (13-1) sur l'ailette de raccordement (13) de manière à réaliser le raccordement d'accouplement concave-convexe. De plus, une nervure de positionnement (13-2) sur le joint d'étanchéité d'extrémité (1) et la fente de positionnement (24) sur la valve antiretour (2) forment un positionnement d'accouplement concave-convexe, empêchant une fuite d'air causée par l'agitation d'un instrument. Un article de ponction (100) utilisant l'ensemble de joint d'étanchéité modulaire (9) est facile et simple à assembler et désassembler, et présente un raccordement stable et de bonnes performances d'étanchéité.
