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.

Automatic dialyzer and dialyzing method

The present invention provides a dialysis coupler assembly comprising a pair of rubber-like elastic tubular couplers, and a pair of joint members for joining the couplers together. Each of the couplers includes an inner channelallowing a connector associated with a medical device to be fitted therein, and a smooth surfaceperpendicular to the longitudinal axis of the coupler. The couplers are adapted to be joined together through the joint members in such manner that the smooth surfaces are in liquid-tight contact with one another. Each of the joint members is adapted to be attached slidably and rotatably onto corresponding one of the couplers, the joint members having first and second engagement portions, respectively. The first and second engagement portions are disposed opposed to one another and adapted to cooperatively engage the joint members with one another so as to allow the smooth surfaces to be brought into liquid-tight contact with one another.
