Medical intravenous administration connectors include a first coupling member (12) having a female luer (22), a valve member having a substantially rigid stem (14) and a substantially resilient body (16) with a sealing surface, and a second coupling member (18) having a fluid coupling extending from one end and an internal valve member support. The valve stem (14) extends into the female luer, and the valve body (16) biases the sealing surface against an annular ring (27) in the first coupling member thereby blocking fluid communication. Vanes are provided in the second coupling member on which the resilient body of the valve sits to center the valve member. The valve may be opened for fluid flow through the assembly by coupling a male luer to the female luer, or by pressure actuation.
Les raccords pour administration médicale par voie intraveineuse de la présente invention sont constitués d'un premier coupleur (12) et d'un second coupleur (18). Le premier coupleur (12) est constitué d'un raccord femelle Luer (22), d'une soupape munie d'une tige sensiblement rigide (14), et d'un corps sensiblement élastique (16) présentant une surface d'étanchéité. Le second coupleur (18) est constitué d'un raccord à fluide partant d'une extrémité, et d'un organe interne de support de soupape. La tige de soupape (14) est disposée dans le raccord Luer femelle, le corps de soupape (16) appliquant la surface d'étanchéité contre une bague annulaire (27) disposée dans le premier coupleur de façon à bloquer la communication fluidique. Des palettes équipant le second coupleur sur lequel repose le corps élastique de la soupape servent à centrer la soupape. Lors du couplage d'un raccord Luer mâle avec un raccord Luer femelle, la soupape est capable de s'ouvrir de façon à laisser passer le fluide dans l'ensemble.
