る。This has the following disadvantages. (A) Since a roller pump for filtration is required, the apparatus is bulky and costly, and the operation is complicated. (B) Since a blood circuit dedicated to the roller pump for filtration was required, the cost was high and the operation was complicated. (C) Since the filtration roller pump forcibly feeds the liquid regardless of the pressure in the blood circuit, it is necessary to frequently adjust the flow rate by the pressure in the blood circuit. The present invention has been made to eliminate these disadvantages.

A branch tube (2) for connecting to a blood circuit is provided from before the throttle (1), and a one-way valve (3) is provided between the branch tubes. The present invention is an online hemofiltration / dialysis apparatus having the above-described configuration.

（１）の後に接続してやれば、再使用が可能になる。Embodiments of the present invention will be described below. (A) A throttle (1) is provided at the outlet of the dialysate supply device. (B) A branch tube (2) is provided before the throttle (1). (C) A one-way valve (3) is provided in the middle of the branch tube. The present invention is configured as described above. When this is used for online hemofiltration dialysis (treatment), the branch tube (2) is used.
Is connected to the chamber of the blood circuit. Since the throttle (1) is provided at the outlet of the dialysate supply device, pressure is generated just before the throttle, and the dialysate is supplied into the blood circuit. Since the pressure of the dialysate may be lower than the pressure in the blood circuit depending on the situation, a one-way valve (3) is provided to prevent the blood from flowing back to the dialysate side. Since the pressure from the dialysate supply device is constant, the flow rate to the branch tube (2) can be adjusted by adjusting the throttle (1). Also,
If the distal end of the branch tube (2) is connected after the squeezing (1) at the time of cleaning after treatment, it can be reused.

然に濾過流量が変化する。According to the present invention, a filtration pump and a dedicated blood circuit therefor are not required. Since filtration occurs at a pressure difference between the blood circuit and the dialysate circuit, a change in pressure in the blood circuit naturally changes the filtration flow rate.
