An automatic reinfusing system which involves no contamination or medical errors or any other operational problems and allows easy and simple operation, without imposing any burden on the medical worker. The automatic reinfusing system includes a hemodialysis circuit, wherein a solution replenishing line has a replenishing solution supply source and an opening and closing arrangement for opening and closing the solution replenishing line, a dialysate supply line and a dialysate discharge line for perfusing to the dialyzer, with a solution feeding arrangement being respectively provided for the dialysate supply line and the dialysate discharge line. At least one filtering and reverse-filtering third solution feeding arrangement capable of normal and reverse rotation and allowing flow rate control serves to perform filtering and reverse filtering on one of the dialysate supply line and the dialysate discharge line in parallel with the solution feeding arrangement. A water-slowing and solution-discharging arrangement, with the blood-feeding means and the filtering and reverse-filtering third solution feeding arrangement are caused to communicate with each other by an interlocking control for controlling, in an interlocked manner, the blood feeding arrangement, the solution feeding arrangement, the opening and closing arrangement for opening and closing the solution replenishing line, and the opening and closing arrangement between the artery connection end the solution replenishing line branching part.
