Abstract:
1. A dialysis apparatus comprising: a blood purification instrument including a blood purification membrane, a blood introducing port, a blood discharging port, a dialysate introducing port and a dialysate discharging port for performing the dialysis purification by contacting blood with dialysate through the blood purification membrane; an arterial blood circuit, with a blood pump, a tip end attachable with a patient via an arterial access needle and base end connected to the blood introducing port of the blood purification instrument; a venous blood circuit with a base end connected to the blood discharging port of the blood purification instrument; a dialysate introducing line connected to the dialysate introducing port of the blood purification instrument for introducing dialysate to the blood purification instrument; a dialysate discharging line connected to the dialysate discharging port of the blood purification instrument for discharging dialysate from the blood purification instrument; a dialysate supplying device for supplying prepared dialysate to the dialysate introducing line; a dialysate infusing line with one end connected to the dialysate introducing line or the dialysate discharging line, another end branched out at a branch point into two flow routes, respectively, 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 including a connector being able to be connected directly to the tip end of the arterial blood circuit, when the arterial access needle is not attached to the patient, 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.
