Abstract

L'invention porte sur un dispositif de connexion pour coupler des conduits de distribution et de réception de fluides médicaux. L'appareil comprend un premier connecteur (1) fixé de façon libérable à un second connecteur formé par un collier (3) à rotation monté sur et autour d'un insert (2). L'insert (2) comprend un matériau qui est plus déformable que le premier connecteur (1) de façon à fournir un joint étanche aux fluides fixe par déformation de l'insert (2) lorsqu'il est amené en contact avec le premier connecteur (1). Des éléments de clavette mâle (16) et femelle (20) fournissent des moyens pour éviter un mauvais appariement des connecteurs. Des moyens supplémentaires (19, 39) sont fournis pour assurer que les connecteurs ne sont pas trop serrés. Dans le cas d'une mauvaise connexion, des ouvertures d'échappement de fluide (13) sont prévues de façon à permettre facilement au fluide de s'échapper du couplage de connexion, servant d'indication d'une mauvaise connexion.
