A self-sealing male Luer connector (10) attaches to any standard female Luer valve to open a flow channel between the two. The self-sealing male Luer connector (10) includes a rigid housing (12) having a distal end (16) with a rigid male Luer connector and a proximal end (14) at which a proximal seal (82) is formed. The distal end (16) of the housing (12) includes a valve seat (70). Located within the housing (12) is a resilient biasing member (34) that biases an actuator (36) into contact with the valve seat (70) to prevent fluid flow through the male connector (10). Upon engagement with a female connector, the actuator (36) is moved in the proximal direction to open the distal valve and then the proximal seal (82). A partial vacuum is formed within the male connector (10) upon disengagement with the female connector that draws any fluids on the external surface of the distal end (16) of the male Luer connector into the male tip.

L'invention concerne un raccord Luer mâle auto-étanche (10) pouvant être fixé à n'importe quelle valve Luer femelle standard en vue de l'ouverture d'un canal d'écoulement intermédiaire. Le raccord Luer mâle auto-étanche (10) comprend un compartiment rigide (12) possédant une extrémité distale (16) pourvue d'un raccord Luer mâle rigide et une extrémité proximale (14) au niveau de laquelle un joint proximal (82) est formé. L'extrémité distale (16) du compartiment (12) comprend un siège de valve (70). Un élément de sollicitation élastique (34) est disposé dans le compartiment (12), cet élément sollicitant un actionneur (36) en contact avec le siège de valve (70) de manière à empêcher un écoulement fluidique à travers le raccord mâle (10). Lors d'une entrée en prise avec un raccord femelle, l'actionneur (36) est déplacé dans le sens proximal de façon à ouvrir la valve distale puis le joint proximal (82). Un vide partiel est formé dans le raccord mâle (10) lors d'une désolidarisation du raccord femelle, ce vide permettant d'aspirer les liquides sur la surface extérieure de l'extrémité distale (16) du raccord Luer mâle dans la pointe mâle.
