Abstract
Système de régulation de débit communément appelé << visuel >> assurant un débit constant et offrant une barrière infranchissable aux bulles d'air même en fin de perfusion. Système caractérisé en ce qu'il comporte un tube central fixe sur lequel coulisse un manchon, muni d'un flotteur, comportant en outre une membrane souple destinée à coopérer avec l'extrémité du tube central fixe, l'ensemble imposant au liquide le traversant un trajet allant de haut en bas et de bas en haut L'invention est destinée à équiper des appareils de perfusion-transfusion.
