A hemodialyzer not causing any medical malpractice such as air inclusion or blood loss during hemodialysis by detecting even a minute connection failure, if any. The hemodialyzer comprising a hemodialyzer (D), a dialyzing fluid supply line (L1), a dialyzing fluid discharging line (L2), an arterial blood line (L3), a venous blood line (L4), first fluid sending means (P1), second fluid sending means (P2), third fluid sending means (P3), a blood pump (P4), a venous chamber (C), an overflow line (L5), a venous pressure monitor line (L6), dialyzing fluid pressure measuring means (M), venous pressure measuring means (M), clamps (CL, CL), control means (G1) which closes the clamp (CL) when a predetermined time has elapsed from the start of the priming, allows the third fluid sending means (P3) to operate in the reverse filtration direction or in the water removing direction simultaneously with the closure of the clamp (CL), and then opens the clamp (CL) when a predetermined time has elapsed, and judging means (J1) which judging the normality of the circuit connection after comparing a variation of the dialyzing fluid pressure or the venous pressure while the clamp (CL) is closed with a predetermined reference value. |
