Abstract

PURPOSE: To provide a body fluid treating device capable of a hemodialysis cure without using physiological saline solution by connecting a dialysis solution reservoir bag halfway in an artery side circuit connected to a dialyzer and a blood inlet through a bifurcated tube. CONSTITUTION: In priming the dialysis solution, the dialysis solution is primed from a dialyzer 12 into a dialyzing chamber 14 through a dialysis solution introducing tube 8. Then, a dislysis solution outlet 18 and a blood inlet 15 are sealed or the vicinity of the blood inlet 15 of a dialysis solution discharging tube 9 and an artery side circuit 4 is clamped. The dialysis solution is filtered backward by an ultrafiltration film (filtration film) 3 to wash the filtration film 3. The washed dialysis solution is discharged by a blood outlet 16 and a vein side circuit 5. Next, the blood outlet 16 is sealed or the vein side circuit 5 is clamped; the blood inlet 15 or the artery side circuit 4 is opened; the dialysis solution is filtered backward to fill a dialysis solution reservoir bag 6 through the artery side circuit 4 and a bifurcated tube 7. Thereafter, a priming is performed from the bag 6 into a blood chamber 13 and the artery side circuit 5.

2. Description of the Related Art
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.
