Dependent claims

A blood purification apparatus comprising:

a circuit for blood purification having an arterial blood circuit and a venous blood circuit that constitute a blood circuit for extracorporeally circulating at least blood of a patient;
a blood purifier for purifying the blood extracorporeally circulated by the blood circuit;
and
a device main body provided with various treatment means for performing blood purification treatment in the blood circuit and the blood purifier,
wherein the blood purification apparatus includes an identification means that allows specific information to be identified, the specific information including an operating condition of the circuit for blood purification or the blood purifier at the time of blood purification treatment or preparation for the treatment, a reading means by which the specific information of the identification means is readable, and a control unit that performs blood purification treatment or preparation for the treatment based on the operating condition in the specific information read by the reading means;
and
wherein the blood purifier has a plurality of connecting portions connectable to the circuit for blood purification, respective connection flow paths are extended from the connecting portions of the blood purifier, and the blood purifier and the circuit for blood purification are configured to be connectable via the connection flow paths, the blood purification apparatus comprises a first connector formed by bundling leading ends of the circuit for blood purification, and a second connector formed by bundling leading ends of the connection flow paths, and connection of the first connector and the second connector allows the circuit for blood purification corresponding to the connecting portions of the blood purifier to communicate with each other, and the identification means is formed in the first connector or the second connector.
