PROBLEM TO BE SOLVED: To provide a hemocatharsis apparatus which is capable of automatically performing hemocatharsis and automatically ending the hemocatharsis while maintaining an adequate blood volume. SOLUTION: This hemocatharsis apparatus 1 has a hemocatharsis section 2, a blood parameter measuring means 6, and a control section 7 which converts the blood parameter to a hematocrit value and controls the hemocatharsis section is accordance with the hematocrit value. At the point of the time the hematocrit value in the blood attains a prescribed value as the hemocatharsis is carried out, the control section 7 instructs the hemocatharsis section 2 to change hemocatharsis conditions, for example, a water removal rate, internal circulating blood flow rate, fluid replacement rate, dialyzate concentration, dialyzate temperature, aqueous sodium chloride solution injection rate, etc., in such a manner that the hematocrit value is decreased. The control section 7 instructs the hemocatharsis section 2 to end the hemocatharsis at the point of the time the decrease rate of the hematocrit value per unit time attains the prescribed value when the hematocrit value decreases by repeating, plural times, the changing of the hemocatharsis conditions.
