Abstract
Provided is a blood purification apparatus configured to keep a blood pump from being driven until a puncture needle is removed. The blood purification apparatus includes a blood circuit which is coupled with a puncture needle punctured into a patient and through which blood from the patient flows; a blood pump that is provided to the blood circuit and delivers liquid in the blood circuit by being driven; a needle removal detector that detects removal of the puncture needle from the patient; and a controller that starts a blood return process to return the blood in the blood circuit to the patient and puts the blood pump in a non-active state in response to determination that the blood return process ends.
