Abstract

Appareil régulateur de débit Le liquide en charge entre par le passage capillaire 2. Il soulève la membrane 3 et découvre ainsi l'entrée du passage de sortie 7. Le débit est fonction de la résistance à l'écoulement de 2 et de la différence entre la pression d'arrivée du liquide et la pression atmosphérique qui règne au-dessus de 3. Application aux appareils de perfusion et de transfusion.Flow regulator device The liquid in charge enters through the capillary passage 2. It lifts the membrane 3 and thus discovers the inlet of the outlet passage 7. The flow rate is a function of the resistance to the flow of 2 and the difference between the inlet pressure of the liquid and the atmospheric pressure which prevails above 3. Application to perfusion and transfusion apparatus.
