ABSTRACT:
Dialyzing elements of capsule form are constituted in a blood circulation path of a dialyzing membrane. Pulse pressure variation is applied to a dialyzing liquid which circulates within the dialyzing vessel in contact with the surface of the dialyzing elements. The pulse pressure variation of the dialyzing liquid causes the tension of the dialyzing membrane surface to vary the diameter of discharge hole on the dialyzing membrane is decreased and increased repeatedly, thereby toxins such as the harmful substances removed by the kidney, which are contained in the blood can be selectively separated and removed so as to carry out blood dialysis.
