Abstract
According to the present invention, there is provided a hemodiafiltration apparatus capable of easily and efficiently removing medium to large molecule solutes at a low cost. Provided is a hemodialysis apparatus which uses a hemodialyzer accommodating a hollow yarn membrane in hemodiafiltration to cause a dialysis fluid to flow from a dialysis fluid circuit side to a blood circuit side by forceful back-filtration via the hemodialyzer, and to cause a fluid in the blood circuit to reflux to a dialysis fluid circuit side by filtration via the hemodialyzer, the hemodialysis apparatus being characterized in that a flux operation of the fluid from the dialysis fluid side to the blood circuit side by the back-filtration, and a reflux operation of the fluid from the blood circuit side to the dialysis fluid circuit side by the filtration are repeated intermittently and for at least a plurality of times.
