A means, apparatus, and system for reducing the net fluid volume deficiency in a patient during a medical treatment process. The invention seeks to modify a batch-type process to achieve the efficiency of a continuous process by precisely measuring the net change in fluid volume within a patient and dispensing the appropriate amount of biological fluids to a patient via IV lines or by recycling blood components into the patient while biological fluids are being withdrawn. The apparatus includes subcomponent lines, valving means, pumping means, load cells, storage chambers, a centrifuge, and centrifuge bowls. The system may have numerous feedback components to accurately measure and control the flow rates and amount of fluid dispensed to a patient.

Cette invention concerne un dispositif, une installation et un système propres à réduire le manque net en volume d'un liquide chez un patient lors d'une intervention médicale. L'objet de cette invention est de modifier un processus en discontinu de manière à atteindre l'efficacité d'un processus en continu. A cette fin, on mesure la variation de volume de liquide dans le corps du patient et l'on administre la quantité appropriée de fluide biologique audit patient via des canalisations intraveineuses, ou bien en recyclant des composants sanguins dans le corps du patient pendant l'extraction de liquides biologiques. L'installation comprend des canalisations pour sous-composants, des systèmes de soupapes, des systèmes de pompage, des cellules de chargement, des chambres de stockage, une centrifugeuse et des cuves de centrifugation. Le système peut être assorti de multiples organes de contrôle conçus pour mesurer et réguler avec précision les débits et le volume de liquide administré au patient.
