Abstract
L'invention concerne un détecteur de goutte. La chambre compte-gouttes 12 comporte une extrémité pointue 12a introduite dans l'extrémité inférieure du réservoir de fluide. L'extrémité 12a est logée dans un boîtier 21 dans lequel est placée une source lumineuse 24 face à un capteur photosensible 25; toute goutte qui tombe dans la chambre 12 agit sur le faisceau de lumière entre 24 et 25 et peut être comptée. Application à la perfusion intraveineuseThe invention relates to a drop detector. The drip chamber 12 has a pointed end 12a introduced into the lower end of the fluid reservoir. The end 12a is housed in a housing 21 in which is placed a light source 24 facing a photosensitive sensor 25; any drop that falls into chamber 12 acts on the light beam between 24 and 25 and can be counted. Application to intravenous infusion
