Abstract

L'invention concerne une installation médicale constituée de plusieurs tuyaux interconnectés qui acheminent des fluides, par exemple du sang, et relient des dispositifs pompant et/ou traitant le sang et/ou des contenants reliés, et de dispositifs de mesure et de régulation de la pression, de la température, de la teneur en gaz et du volume du fluide pour le traitement de patients. Les contenants sont constitués d'au moins deux feuilles et/ou plaques superposées, juxtaposées et/ou fixées par des parois intermédiaires. L'invention a pour objet de réduire les volumes de fluides utilisés en raccourcissant la longueur des tuyaux tout en respectant les possibilités de réglage, en augmentant la compacité de l'installation et en réduisant les temps de montage lors de la préparation d'interventions médicales. Dans cette optique, l'invention propose que plusieurs tuyaux ou tous les tuyaux (14) et les boîtiers des dispositifs (2; 3; 4; 5; 6) soient intégrés dans le système de feuilles et/ou de plaques de telle façon qu'une zone supérieure (19) des tuyaux et des boîtiers des dispositifs soit formée par la feuille et/ou la plaque (17) supérieures et qu'une zone inférieure (20) des tuyaux et des boîtiers des dispositifs soit formée par la feuille et/ou la plaque inférieurs (18).
