In hemodialysis treatment, a dialysis membrane is placed in a dialyzer to divide it into a blood chamber and a dialysis chamber, and blood in the blood chamber and dialysate in the dialysate chamber are circulated by countercurrent flow to the blood chamber. It is carried out by moving the unnecessary substances of 1. into the dialysate. However, when the dialyzer and the arteriovenous circuit connected to it are primed with physiological saline before the start of treatment, and when the blood drawn into the dialyzer and arteriovenous circuit is returned, the saline solution is also used. Since it was kept flowing, a large amount of physiological saline had to be consumed. Therefore, the present inventor has earnestly studied a body fluid treatment device capable of performing hemodialyzer treatment without using physiological saline, and has arrived at the following invention.
