A blood purification apparatus comprising:

• a blood purifier that has an inner portion divided by a semi-permeable membrane into a first portion and a second portion;
• a vascular access flow path that is connected to the blood purifier and is in communication with the first portion;
• a cleaning solution flow path that is connected to the blood purifier and is in communication with the first portion;
• and
• a drainage flow path that is connected to the blood purifier and is in communication with the second portion, wherein
• the cleaning solution flow path is provided with a blood pump capable of bidirectionally feeding a fluid, and
• a first open-close valve is provided in the vascular access flow path and a second open-close valve is provided in the drainage flow path,
