Abstract

L'invention porte sur un dispositif médical d'injection de fluide qui comprend une unité de commande d'injection qui commande le fonctionnement d'un mécanisme d'actionnement de seringue conformément à des données de commande d'injection préréglées pour effectuer une injection de fluide médical. Avant l'injection médicale, une unité d'entrée de données acquiert des données de fonction rénale sur un sujet devant être visualisé, et une unité de réglage de commande génère les données de commande d'injection correspondant aux données de fonction rénale acquises et règle les données de commande d'injection dans l'unité de commande d'injection. Ainsi, le fonctionnement d'une injection de fluide médical correspondant à la fonction rénale du sujet peut être mieux commandé. Il en résulte que l'injection d'un fluide médical tel qu'un milieu de contraste chez le sujet ayant une insuffisance rénale peut se faire de la même façon que chez des sujets devant être visualisés ayant une fonction rénale normale peut être évitée de façon simple et infaillible.
