CA 2361641

A cartridge (10) is provided containing sodium bicarbonate in solid form. The cartridge (10) is usable in a haemodialysis machine for continuously producing a buffer solution, which is mixed with another solution to produce a dialysis solution. The cartridge (10) also contains a solid acid or acid anhydride, or carbon dioxide gas. This has been found to overcome problems caused by a temporary high pH in the dialysis solution during the early stages of a dialysis operation.

La présente invention concerne une cartouche (10) contenant du bicarbonate de sodium sous forme solide. La cartouche (10) est utilisable dans une machine d'hémodialyse afin de produire en continu une solution tampon qui est mélangée avec une autre solution pour produire la solution de dialyse. Cette cartouche (10) contient aussi un acide ou un anhydride solides, ou du dioxyde de carbone sous forme de gaz, ce qui permet de surmonter des problèmes provoqués par une augmentation temporaire de la valeur du pH dans la solution de dialyse lors des premiers moments d'une opération de dialyse.
