CA 2318600

Apparatuses for use in whole-body hypothermia include a high-flow hyperthermia circuit coupled to a low-flow dialysis circuit in a manner which reduces tensioning of membranes in the dialyzer (152) of the dialysis circuit. The arrangement thereby allows proper membrane movement to assist in mixing a sorbent suspension (176) circulated on the sorbent side of the dialyzer. Additional dialysis apparatuses include advantageous disposable packs (300) including the dialyzer (152), sorbent heat exchangers (186) arranged to cooperate with heating elements on base units of the apparatuses, and adaptations for very high flow rates useful in the hyperthermic treatment of cancers.

L'invention se rapporte à des appareils destinés au traitement par hyperthermie généralisée et comportant un circuit hyperthermique à grand débit couplé à un circuit de dialyse à faible débit permettant de réduire la tension de membranes dans le dialyseur (152) du circuit de dialyse. Cet agencement permet aux membranes de se déplacer correctement pour faciliter le mélange d'une suspension (176) de sorbants qui circule du côté absorbant du dialyseur. L'invention concerne aussi d'autres ensembles avantageux de dialyse composés du dialyseur (152), d'échangeurs thermiques (186) de sorbants disposés de façon à coopérer avec des éléments chauffants situés sur des unités de base, ainsi que des adaptations de ces appareils aux très hauts débits nécessaires au traitement hyperthermique de cancers.
