    • A method and device for blood treatments that use fluids such as dialysate and replacement fluid for renal replacement therapy. In an embodiment, fluid is passed either by pump or passively by gravity feed, through a microporous sterilization filter from a fluid source to a replacement fluid container. The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment. As a result, the sterilization filter can have a small capacity. In another embodiment, a filter is placed immediately prior to the point at which the sterile fluid is consumed by the treatment process. The latter may be used in combination with the former embodiment as a last-chance guarantee of sterility and/or that the fluid is free of air bubbles. It may also be used as the primary means of sterile-filtration.
    • 用于血液处理的方法和装置,其使用诸如透析液和替代液的流体用于肾替代治疗。 在一个实施例中,流体通过泵或被动地通过重力进料通过微孔灭菌过滤器从流体源传递到替换流体容器。 后者形成可在治疗期间使用的批次。 在处理之前形成批次的优点是过滤速率与处理过程中的消耗速率不一致。 结果,灭菌过滤器可以具有小容量。 在另一个实施方案中,过滤器被立即放置在无菌流体被处理过程消耗的点之前。 后者可以与前一个实施方案组合使用,作为不育的最后机会保证和/或流体没有气泡。 它也可以用作无菌过滤的主要手段。
