Abstract

La valve comprend trois éléments longitudinaux (2) situés perpendiculairement par rapport à la base de l'équipement de transfusion de façon à ce qu'ils soient équidistants et qu'il délimitent l'entrée de la cavité de forme cylindrique (3) de façon à renfermer un autre élément de forme sphérique (1). La position dans le parcours vertical que suit cet élément sphérique (1) dépend de la quantité de fluide contenu dans le réservoir de l'équipement de transfusion. A l'intérieur de cette cavité (3) est logé un élément en caoutchouc (4), pourvu d'un orifice central, et destiné à assurer une fermeture hermétique à travers l'accouplement parfait avec l'élément sphérique (1). La présente invention vise à obturer complètement le conduit une fois que la solution a été administrée dans le but d'assurer un plus grand contrôle de sécurité pour le patient et le professionnel.
