Abstract

De manière générale, cette invention concerne des procédés et des dispositifs permettant de mettre en oeuvre une recirculation en circuit fermé de liquide céphalo-rachidien (LCR), en principe d'origine synthétique, à travers les régions cérébrales et rachidiennes du corps et l'équipement de régénération et de revitalisation. Dans une réalisation préférée présentée sous forme d'une cassette, ce dispositif comprend un ensemble modulaire de matériel jetable, arrangé de préférence d'une manière permettant une utilisation rapide et aisée en cas d'urgence. Cette cassette contient de préférence tous les composants ou la plupart des composants qui composent le circuit de liquide permettant le conditionnement du LCR thérapeutique recirculé en provenance et en direction du patient.
