cc is fed at a pressure of 0 to 0.2 kg / cm 2 to one side of the hemofilter as shown by arrow 11 , and blood is supplied at a rate of 18 per minute.
0 to 200 cc is fed to the other side of the hemofilter at 0 to 0.2 kg / cm 2 . If this state is continued for 1 hour, the efficiency will decrease. So when raising the pressure of the dialysate 0.3~0.4kg / cm 2, dialysate 3
As indicated by the middle arrows 17 and 18, the harmful substance having a large molecular weight, which pushed into the blood side and caused the clogging of the dialysis membrane, was pushed back to eliminate the clogging. This operation is performed instantly, and the clogging is eliminated instantly. It is more effective to repeat the rise and fall of the pressure in the above.

環管６、７を連結する。[Embodiment 2] An embodiment of the apparatus of the present invention will be described with reference to FIGS. The console 1 and the hemofilter 2 are connected by a dialysate inlet pipe 3 and a discharge pipe 4 having a branch portion A interposed therebetween, and the hemofilter 2 has a blood circulation pipe 6 between the patient 5 and the hemofilter 2.

おける流速を早くしなければならない。In the above, when the dialysis membrane 16 installed in the hemofilter 2 is clogged, the solenoid valve 13 is closed. At that time, the dialysate is discharged through the auxiliary valve 15. However, since the passage of the auxiliary valve 15 is regulated to have a smaller cross-sectional area than the passage of the solenoid valve 13, the amount of the dialysate to be discharged is larger than that of the dialysate. Will be less. Therefore, in order to discharge the same amount, it is necessary to increase the pressure of the discharged liquid and increase the flow velocity in the passage of the auxiliary valve.

よって、有害粒子２０がバラバラになるので、目詰りは
解消される。Therefore, the pressure of the dialysate in contact with the dialysis membrane 16 becomes higher than that on the blood side (usually equal pressure).
Like Nos. 7 and 18, the harmful particles 20 clogged in the permeation holes 19 of the dialysis membrane 16 are pushed back into the blood. Due to this backflow, the harmful particles 20 are scattered and the clogging is eliminated.

られる。Although it depends on the state of blood, it is recognized that clogging is usually increased after about 1 hour of dialysis.
By backwashing at least once an hour, dialysis can be performed with almost the same efficiency at all times. Therefore, it is possible to shorten the dialysis time.
【００１７】例えば従来４時間の透析は必須であった

きる効果がある。According to the present invention, the flow rate of dialysate can be adjusted.
More to the circulating pressure of the dialysate to the variable, so it caused the pressure difference between the blood pressure and the dialysis solution, next easy backwash of the dialysis membrane, the other part
There is an effect that clogging can be improved easily and quickly without affecting the.
