- 摘要：
PROBLEM TO BE SOLVED: To provide a hemodialyzer which can easily detect a trouble causing blood removal failure.
SOLUTION: 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.
