CONTROLLER FOR ADJUSTING RATIO OF FLOW RATES OF MEDICINAL PREPARATIONS Russian patent published in 1997 - IPC

FIELD: medical engineering, equipment for intravenous and intravascular administration of drugs. SUBSTANCE: apparatus comprises two reservoirs filled with medicaments, distributor connected to reservoirs and to main pipeline connected to patient. Distributor is made in the form of two flow controllers, its movable parts are connected via resilient tubes to drug-filled reservoirs. Casing of first flow controller is connected to second reservoir, and casing of second flow controller, to first reservoir. Both reservoirs on spring-urged base plates carried by bed frame so as to render adjustable mutual position of flow controllers and reservoirs in vertical direction, main pipeline connected to inlet of each drug flow controller. EFFECT: uniform dispensing of mixture of medicinal preparations; possibility to control ratio of drug flow rates. 1 dwg
