ABSTRACT:
An automatic dialyzer for purifying blood brought into contact with a dialysate via a semi-impermeable membrane. The dialyzer includes at least a blood circulating system and a dialysate supply/discharge system, wherein the blood line of the blood circulating system is connected to an overflow line having a reversibly-rotatable blood pump, a blood chamber, and an open/close device for overflowing of liquid from the blood chamber to the outside of the blood line. Liquid supply means is provided to a first bypass line and/or a second bypass line for supplying liquid in both forward and reverse directions to enable regulation of the supply amount of the dialysate for water removing/liquid replenishing. The supply speed of the liquid supply device and the supply speed of the blood pump are regulatable in conjunction with each other. Also provided is a dialyzing method using the automatic dialyzer.
