(FR) DISPOSITIF DE MÉLANGE, TUBE DE MÉLANGE, SYSTÈME D'INJECTION DE SOLUTIONS DE MÉDICAMENTS ET PROCÉDÉ DE MÉLANGE DE SOLUTIONS DE MÉDICAMENTS
Abstract
(EN) To provide a mixing device, a mixing tube, a drug solution injecting system, and a drug solution mixing method capable of evenly and efficiently mixing a plurality of kinds of drug solutions. The mixing device according to the present invention includes: a swirling flow generating chamber; a first inflow opening for introducing a first drug solution into the swirling flow generating chamber in a direction parallel to a central axis of the swirling flow; a second inflow opening for introducing a second drug solution into the swirling flow generating chamber so as to generate a swirling flow of the second drug solution having a specific gravity lower than that of the first drug solution; an outflow opening for discharging a mixed drug solution; and a narrowing chamber which is interposed between the swirling flow generating chamber and the outflow opening and has a space continuously narrowed toward the outflow opening.
(FR) L'invention concerne un dispositif de mélange, un tube de mélange, un système d'injection de solutions de médicaments et un procédé de mélange de solutions de médicaments capable de mélanger de manière homogène et efficace une pluralité de types de solutions de médicaments. Le dispositif de mélange, selon la présente invention, comprend : une chambre de génération d'écoulement tourbillonnant ; une première ouverture d'entrée d'écoulement pour l'introduction d'une première solution de médicaments à l'intérieur de la chambre de génération d'écoulement tourbillonnant dans une direction parallèle à un axe central de l'écoulement tourbillonnant ; une seconde ouverture d'entrée d'écoulement pour l'introduction d'une seconde solution de médicaments à l'intérieur de la chambre de génération d'écoulement tourbillonnant afin de générer un écoulement tourbillonnant de la seconde solution de médicaments ayant une gravité spécifique inférieure à celle de la première solution de médicaments ; une ouverture de sortie d'écoulement pour évacuer une solution de médicaments mélangée ; et une chambre de rétrécissement qui est interposée entre la chambre de génération d'écoulement tourbillonnant et l'ouverture de sortie d'écoulement et a un espace continuellement rétréci jusqu'à l'ouverture de sortie d'écoulement.
