摘要

PPROBLEM TO BE SOLVED: To provide a hemodialyzer which can easily detect a trouble causing blood removal failure. PSOLUTION: As the figure 1 shows, the hemodialyzer includes a dialysis apparatus 1, a blood circuit 2 (21 and 22), a blood pump 3, a priming fluid supplying line 4, a vein side air trap chamber 23, a dialyzing fluid circuit 5 (51 and 52), a dialyzing fluid pump 6 and a water removal pump 7. The vein side blood circuit 21 in the upstream of the blood pump 3 is provided with an ultrasonic blood flow meter 8. The blood flow meter 8 measures the volume of blood in the artery side blood circuit 21: if the measured blood volume is less than the flow volume set in the blood pump 3, the dialysis completion time is recalculated and displayed based on the measured blood flow volume. If the ratio of measured blood flow volume and the set blood flow volume (blood flow volume ratio) is less than a certain ratio, alarm is sounded. PCOPYRIGHT: (C)2008,JPO&INPIT

要解决的问题:提供一种血液透析器,该血液透析器可以轻松检测到导致血液清除失败的故障。解决方案:如图1所示,血液透析器包括透析设备1,血液回路2(21和22),血泵3,灌注流体供应管线4,静脉侧空气收集腔23,透析液回路5(51和52),透析液泵6和除水泵7。在血液泵3的上游的静脉侧血液回路21设置有超声波血液流量计8。血液流量计图8测量了动脉侧血液回路21中的血液量:如果测量的血液量小于在血泵3中设置的流量,则基于测量的血液量重新计算并显示透析完成时间。如果测得的血流量与设定的血流量之比(血流量比)小于某个比率,则会发出警报。
