Dialysepatron som inneholder natriumbikarbonat og fremgangsmåte for å hindre tempor¶r ökning i pH i endialyselösning

摘要

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.
