Abstract: A blood purification apparatus includes a line section, a duplex pump, and a control unit. The line section includes a dialysate introduction line and a drain-liquid discharge line. The control unit is configured to execute a blood purification treatment process and a defatting washing process. The blood purification treatment process is executed when blood purification treatment is performed in which dialysate is delivered to a dialyzer. The dialysate is prepared by mixing an A-drug solution and a B-drug solution introduced into the line section and diluting the A-drug solution and the B-drug solution to predetermined concentrations. The defatting washing process is executed when defatting washing is performed in which oil and fat in the line section is removed by causing a sodium carbonate solution to flow through the line section. The sodium carbonate solution is obtained by heating the B-drug solution introduced into the line section.

The defatting washing process is executed when defatting washing is performed where oil and fat in the line section is removed by causing a sodium carbonate solution obtained from the B-drug solution introduced into the line section to flow through the line section. The control unit uses a heating unit and a deaerator when executing a bicarbonate-solution-generating process where the sodium carbonate solution is generated by a predetermined amount while carbon dioxide is discharged.

Abstract: A blood purification apparatus with a blood circuit that allows a patient's blood to extracorporeally circulate and a blood purifier connected to the blood circuit and that purifies the blood in extracorporeal circulation are attachable, the blood purification apparatus including a dialysate introduction line through which dialysate is introduced into the blood purifier; a dialysate drain line through which waste dialysate resulting from blood purification performed by the blood purifier is drained from the blood purifier; and a concentration-detecting unit that detects a concentration of a predetermined substance in the waste dialysate flowing through the dialysate drain line.

Abstract: There is provided a blood purification apparatus with which the efficiency of dialysate purification can be improved and the reduction in the amount of electrolytes contained in dialysate and necessary for treatment can be suppressed. The blood purification apparatus includes a storage device capable of storing a predetermined amount of dialysate that is necessary for blood purification treatment, a dialysate circulation line through which the dialysate is allowed to circulate by introducing the dialysate in the storage device into the dialyzer and draining waste liquid from the dialyzer into the storage device, and the dialysate purification device that purifies the dialysate in the dialysate circulation line. A treatment state in which the dialysate is allowed to be introduced into the dialyzer without flowing through the dialysate purification device and a purification state in which the dialysate is allowed to be purified by the dialysate purification device are taken switchably.

Abstract: A blood purification apparatus including a blood circuit including an arterial blood circuit and a venous blood circuit and that allows a patient's blood to extracorporeally circulate from a distal end of the arterial blood circuit to a distal end of the venous blood circuit; a blood purifier between the arterial blood circuit and the venous blood circuit that purifies the blood flowing through the blood circuit having a blood flow route through which the blood extracorporeally circulating through the blood circuit flows and a dialysate flow route through which dialysate flows, the blood flow route and the dialysate flow route being separated from each other by a blood purification membrane for purifying the blood; an ultrafiltration unit that performs ultrafiltration by filtering out water from the blood in the blood flow route through the blood purification membrane and draining the water through the dialysate flow route; and a substitution-fluid supply unit that supplies substitution fluid into the blood c

Abstract: A blood purification apparatus that accurately calculates the colloid osmotic pressure of a patient's blood. A dialyzer included in the blood purification apparatus has thereinside blood flow routes and dialysate flow routes that are separated from each other by hollow fibers. An ultrafiltration pump draws out water from the blood in the blood flow routes through the hollow fibers into the dialysate flow routes. Four detecting units measure the pressures of liquid flowing into the blood flow routes, the liquid discharged from the blood flow routes, dialysate flowing into the dialysate flow routes, and the dialysate discharged from the dialysate flow routes. The pressures at the four positions, the transmembrane pressure difference can be calculated. The blood flow routes are filled with a priming solution, and the transmembrane pressure difference (TMPa) is measured. Subsequently, the blood flow routes are filled with the patient's blood, and the transmembrane pressure difference (TMPb) is measured.
