Title (EN) MEDICAL CONNECTOR
(FR) RACCORD MÉDICAL
(JA) 医療用コネクタ
Abstract:
(EN) An improved medical connector configured in such a manner that the diameter of a connector opening is further reduced with the fixation strength of a valve element maintained at a sufficient level. Annular grooves (54, 56) are formed in both the inner and outer surfaces (50, 52) of the outer peripheral portion of an elastic valve element (38) to form an annular constricted section (58).  The outer peripheral side from the constricted section (58) is made to serve as an annular fixation section (46).  A valve receiving seat (68) is formed at the inner peripheral edge of an opening (65) in a housing (12), and an annular ring (42) is fixed to the opening (65) to sandwich and support the annular fixation section (46) between the valve receiving seat (68) and the annular ring (42).  Engaging projections (70, 80) formed on mutually facing surfaces of the valve receiving seat (68) and the annular ring (42) are engaged with the annular grooves (54, 56), and either the engaging projection (70) and/or the engaging projection (80) is made to consist of projections divided in the circumferential direction.
(FR) L'invention porte sur un raccord médical amélioré, configuré de telle sorte que le diamètre de l'ouverture du raccord est davantage réduit par le maintien à un niveau suffisant de la force de fixation d'un élément de soupape. Des rainures annulaires (54, 56) sont ménagées à la fois dans les surfaces intérieure et extérieure (50, 52) de la partie périphérique extérieure d'un élément de soupape élastique (38) afin de constituer une section annulaire resserrée (58). Le côté périphérique extérieur à partir de la section contrainte (58) est conçu pour servir de section annulaire de fixation (46). Un siège de réception de soupape (68) est constitué au niveau du bord périphérique intérieur d'une ouverture (65) dans un boîtier (12), et une bague annulaire (42) est fixée à l'ouverture (65) pour prendre en sandwich et porter la section de fixation annulaire (46) entre le siège de réception de soupape (68) et la bague annulaire (42). Des saillies d'engagement (70, 80) constituées sur des surfaces opposées l'une à l'autre du siège de réception de soupape (68) et de la bague annulaire (42) s'engagent dans les rainures annulaires (54, 56) et l'une ou l'autre de la saillie d'engagement (70) et/ou de la saillie d'engagement (80) sont constituées de saillies divisées en direction périphérique.
(JA)  弁体の固着強度を確保しつつ、コネクタ開口部の更なる小径化を図ることの出来る、改良された医療用コネクタを提供する。 弾性弁体38の外周部分の内外両面50,52に環状溝54,56を形成することによって環状の括れ状部58を設けると共に、括れ状部58よりも外周側を環状固定部46とする一方、ハウジング12の開口部65の内周縁部に弁受座68を形成すると共に、開口部65に環状リング42を固定して、これら弁受座68と環状リング42で環状固定部46を挟んで支持し、更に、弁受座68と環状リング42の対向面上に形成した係止突部70,80を環状溝54,56に係止させて、それら係止突部70,80の少なくとも一方を周方向で分断された複数の突起形状とした。
