Abstract

L'invention concerne des dispositifs de perfusion des solutions liquides. Le dispositif comporte un régulateur de débit goutte-à-goutte et un boîtier en deux parties 52, 54, contenant une bille obturation 68, monté avec du jeu entre un siège d'obturation supérieur 62, percé d'un passage 64 pour le liquide, et un autre passage 78 ménagé dans le fond 76 du boîtier. Des nervures 80, prévues au fond du boîtier, empêchent la bille 68 d'obturer le passage inférieur 78, ladite bille 68 étant susceptible d'être appliquée de manière étanche contre une lèvre annulaire élastique 66 du siège 62, en délimitant sur la bille un cercle qui correspond à une ouverture angulaire d'environ 60 degrés au centre de la bille. Application aux dispositifs de perfusion, notamment à plusieurs réservoirs.
