Claim 5:
6. The blood purification apparatus according to claim 1, further comprising:
a feeding-liquid storage that stores, as feeding liquid, dialysate to be fed to the blood purifier or substitution fluid to be fed through the blood purifier to a blood circuit through which the blood of the patient circulates;
a feeding-liquid temporary chamber that stores the feeding liquid received from the feeding-liquid storage; and
a feeding-liquid introduction line through which the feeding liquid stored in the feeding-liquid storage flows into the feeding-liquid temporary chamber,
wherein the remaining-amount-detecting unit includes a weighing device that measures a total weight of the feeding-liquid temporary chamber and the drain-liquid temporary chamber,
wherein the draining process is an initialization process in which the amount of drain liquid in the drain-liquid temporary chamber and an amount of feeding liquid in the feeding-liquid temporary chamber are initialized by continuing the draining until the reference remaining amount is reached by the drain liquid in the drain-liquid temporary chamber while continuing feeding until a reference feeding amount is reached by the feeding liquid in the feeding-liquid temporary chamber, and
wherein the judging unit judges whether or not the reference remaining amount is reached by the drain liquid in the drain-liquid temporary chamber in the initialization process from a result of measurement by the weighing device while the amount of feeding liquid in the feeding-liquid temporary chamber is maintained at a constant value.
