    • PROBLEM TO BE SOLVED: To provide a dialysate filter in which leak check of the dialysate filter can be quickly and precisely done.SOLUTION: A hemodialysis device 1 is provided with a dialysate filter, and is provided with a testing passage for discharging fluid from one of a space on the inflow side of the dialysate filter and a space on the discharge side of the dialysate filter, an opening means 42 for opening the other space to the atmosphere, a pressure detection means for detecting a pressure variation in the one space, and an assessing means 54 for assessing the quality of the dialysate filter on the basis of the pressure variation. A control means causes the dialysate to be discharged from the one space by a dialysate pump 52 via the testing passage, and causes the other space to be opened to the atmosphere by the opening means 42, and when the one space is depressurized to a first negative pressure, the one space is depressurized to a second negative pressure by a draining means. The assessing means assesses that the dialysate filter is good when the pressure detection means does not detect a pressure variation from the second negative pressure, and the assessing means assesses that the dialysate filter is bad when the pressure detection means detects a pressure variation.
    • 要解决的问题:提供透析液过滤器,其中可以快速和精确地完成透析液过滤器的泄漏检查。 解决方案:血液透析装置1设置有透析过滤器,并且设置有用于从透析液过滤器的流入侧的空间中的一个排出流体的测试通道和透析液过滤器的排出侧的空间 ,用于将另一空间打开到大气的打开装置42,用于检测一个空间中的压力变化的压力检测装置,以及用于基于压力变化来评估透析液过滤器的质量的评估装置54。 控制装置使得透析液经由测试通道由透析泵52从一个空间排出,并且通过打开装置42使另一空间向大气打开,并且当一个空间被减压到第一 负压,通过排水装置将一个空间减压至第二负压。 评估装置评估当压力检测装置没有检测到来自第二负压的压力变化时透析液过滤器良好,并且当压力检测装置检测到压力变化时,评估装置评估透析过滤器是不好的。 版权所有(C)2013,JPO&INPIT
