Abstract
L'invention concerne les dispositifs de perfusion dont le débit est commandé par des moyens électroniques. Le dispositif de perfusion 10 comporte notamment un détecteur de goutte 19 qui détecte la chute de chaque goutte dans la chambre compte-gouttes 12, une valve à commande électromagnétique 15 dont chaque ouverture détermine la formation d'une goutte, et un circuit électronique de commande 18 qui permet de commander avec précision la cadence de formation des gouttes. Application à la perfusion intraveineuse.The invention relates to infusion devices whose rate is controlled by electronic means. The infusion device 10 comprises in particular a drop detector 19 which detects the fall of each drop into the drip chamber 12, an electromagnetically controlled valve 15, each opening of which determines the formation of a drop, and an electronic control circuit 18 which enables the rate of formation of the drops to be controlled with precision. Application to intravenous infusion.
