Abstract
L'invention vise un dispositif de réglage du débit d'un fluide, notamment pour une perfusion médicale. Le dispositif de réglage comporte un boîtier 10 à chambre de dosage pulsatoire 47 pourvue d'organes mobiles d'obturation à l'entrée 45 et à la sortie 56, asservis à des poussoirs d'actionnement 51, 58 à mouvement alternatif réglé par l'appareil de commande. Celui-ci comporte des moyens chronométriques provoquant à des intervalles de temps prédéterminés des changements d'état électronique d'un circuit de commande. Un dispositif d'asservissement, associé aux moyens chronométriques provoque le fonctionnement des poussoirs d'obturation 51, 58, par exemple au moyen d'un électro-aimant à bascule agissant sur un ressort à lame oscillant 61, qui porte les deux poussoirs 51, 58, l'électronique du circuit de commande est réalisée de préférence en technique CMOS, pour réduire l'encombrement et la consommation, et assurer une grande fiabilité. Application aux dispositifs de réglage de débit, notamment pour des perfusions médicales.
