PROBLEM TO BE SOLVED: To provide a blood purification device capable of easily and correctly determining propriety of fluid block by a check valve, before treatment.SOLUTION: A blood purification device comprises: a blood circuit; a dialyzer 1; a dialysis fluid introduction line L1 and a dialysis fluid discharge line L2; pressure detection means (α-γ); dialysis fluid take-out means 10; a dialysis fluid supply line La; and a check valve 18 for blocking flow of the fluid going from the blood circuit to the dialysis fluid introduction line L1. The blood purification device further comprises: control means 19 for generating pressure difference between the blood circuit side and the dialysis fluid introduction line L1 side sandwiching the check valve 18; monitor means 20 for monitoring change of a detection value of the pressure detection means based on pressure difference; and determination means 21 for determining propriety of fluid block by the check valve 18, based on change of the detection value of the pressure detection means. |
