Abstract

An object of the present invention is to provide a blood purification device which eliminates the need for a priming liquid recovery bag connected only at the time of priming, thereby reducing the cost for priming. By driving the blood pump (P1) to supply the priming liquid to the blood circuit (1) for priming, when the priming liquid in priming is discharged, the priming liquid supplied to the blood circuit (1) can be The liquid is discharged through the dialysate discharge line, and the priming liquid supplied to the blood circuit (1) can be discharged into the dialysate discharge line (L2) through the fluid replacement line (L3).

Description

technical field [0001] The present invention relates to a blood purification device for purifying a patient's blood while circulating it extracorporeally. Background technique [0002] Generally, a blood purification device for dialysis treatment includes: an arterial side blood circuit and a venous side blood circuit constituting a blood circuit for extracorporeal circulation of blood of a patient; The blood purification mechanism; the device main body, in which various treatment mechanisms such as a blood pump for performing blood purification treatment through the blood circuit and the blood purification mechanism are provided. Blood vessel contact probes or puncture needles (arterial side puncture needles and venous side puncture needles) can be respectively installed at the front ends of the arterial side blood circuit and the venous side blood circuit. [0003] In addition, for example, after the arterial side puncture needle and the venous side puncture needle are pu...
