    • A method for reprocessing dialyzer cartridges (13) used with kidney dialysis machines is provided. The method involves filling the blood (19, 21) and dialysate (23, 25) compartments of the dialyzer (13) with an aqueous solution containing citric acid at a concentration of 1.0-5.0 wt. %, e.g., 1.5 wt. %, and then subjecting the dialyzer (13) to an elevated temperature above 90 °C and below 100 °C, e.g., 95 °C, for a period of at least 15 hours, e.g., 20 hours. Although citric acid is non-toxic and the temperature used is below the boiling point of water, the process has been found to produce a fully sterilized dialyzer (13). After reprocessing, the aqueous citric acid solution is preferably left in the dialyzer (13) where it acts as a bacteriostatic agent during storage. Essentially no damage to the dialyzer (13) and, in particular, to its semipermeable membrane (11) results from either the reprocessing or storage procedures.
    • 提供了用于再加工肾透析机使用的透析器药筒(13)的方法。 该方法涉及用含有浓度为1.0-5.0wt%的柠檬酸的水溶液填充透析器(13)的血液(19,21)和透析液(23,25)隔室。 %,例如1.5wt。 然后使透析器(13)经受高于90℃且低于100℃(例如95℃)的升高的温度至少15小时,例如20小时的时间。 尽管柠檬酸是无毒的并且所用的温度低于水的沸点,但该方法已被发现产生完全消毒的透析器(13)。 在再加工之后,优选将柠檬酸水溶液留在透析器(13)中,在储存过程中其充当抑菌剂。 基本上不会损坏透析器(13),特别是其半透膜(11),因为后处理或存储过程。
