PROBLEM TO BE SOLVED: To provide a system capable of easily, accurately and quickly measuring an actual blood flow rate in hemodialysis. SOLUTION: The actual blood flow rate measuring system of a hemodialysis device is provided with a replenishing liquid injection means for injecting a replenishing liquid to the upstream side of a blood pump, a pressure detection means for detecting a pressure on the upstream side of a hemodialysis element, and an actual blood flow rate computing means for calculating the actual blood flow rate in the hemodialysis from the set blood flow rate of the blood pump and detected pressures by the pressure detection means before and after injecting the replenishing liquid into a blood flow passage by the replenishing liquid injection means. By this system, in spite of extremely simple circuit constitution, just by measuring the pressure behavior of a blood circuit before and after injecting the replenishing liquid, the actual blood flow rate is easily, accurately and quickly calculated. Thus, whether or not specifications suitable for the hemodialysis are set, the efficiency of dialysis using the hemodialysis element, and dialysis setting time are determined accurately.
