摘要： An object of the present invention is to provide a dialysis apparatus which can prevent the generation of excessive positive pressure in the flow route between the blood pump and the dialysate infusing pump although there would be caused an error in the flow rate of the blood pump and the dialysate infusing pump during the blood-returning process. According to the present invention, there is provided a dialysis apparatus comprising a dialysate infusing line, one end of which being connected to the dialysate introducing line or the dialysate discharging line, the other end-side being branched out at a branch point into two flow routes respectively having a first branch end and a second branch end, the first branch end being able to be connected to the arterial blood circuit or the venous blood circuit, and the second branch end being able to be connected to the tip end of the arterial blood circuit during the blood-returning process, and a dialysate infusing pump arranged on the dialysate infusing line at a connection-side of the dialysate infusing line relative to the dialysate introducing line or the dialysate discharging line from the branch point for supplying the dialysate of the dialysate introducing line or the dialysate discharging line to the first branch end and the second branch end.

摘要： To provide a blood purification apparatus configured such that a B-drug solution used in a blood purification treatment process is also utilized as an alkaline chemical in a defatting washing process, and such that assured and smooth performance of the defatting washing process is achieved. A blood purification apparatus includes a line section, a duplex pump (1), and a control unit (13). The line section includes a dialysate introduction line (L1) and a drain-liquid discharge line (L2). The control unit (13) 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 (C). The dialysate is prepared by diluting an A-drug solution and a 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 obtained from the B-drug solution introduced into the line section to flow through the line section. The control unit (13) uses a heating unit (4) and a deaerator (5) when executing a bicarbonate-solution-generating process in which the sodium carbonate solution is generated by a predetermined amount while carbon dioxide is discharged, and when executing, after the bicarbonate-solution-generating process, the defatting washing process in which the sodium carbonate solution is used.

摘要： To provide a blood purification apparatus configured such that a B-drug solution used in a blood purification treatment process is also utilized as an alkaline chemical in a defatting washing process and such that favorable performance of defatting washing is achieved with the removal of carbon dioxide generated during the defatting washing process. A blood purification apparatus includes a line section, a duplex pump 1, and a control unit 13. The line section includes a dialysate introduction line L1 and a drain-liquid discharge line L2. The control unit 13 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 C. 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 control unit 13 causes carbon dioxide to be discharged to the outside of the line section during the defatting washing process. The carbon dioxide is generated when the sodium carbonate solution is caused to flow.
