The invention relates to the field of blood purifying equipment, and discloses a dialyzate regenerating device and a blood purifying
system. The dialyzate regenerating device comprises a first flow pump, a purifying unit, a
liquid storage pot, a second flow pump and an outer cavity of a dialyzer which communicate with each other through pipelines to form a circulating loop, wherein an
ion concentration adjusting unit and an acid-base balance adjusting unit are further arranged on the pipeline between the purifying unit and the
liquid storage pot; an
electrolyte adjusting unit is further connected on the pipeline between the output end of the
liquid storage pot and the inlet of the outer cavity of the dialyzer; and a sensor group used for detecting the ionic concentration, the pH value and the amount of liquid in the liquid storage pot is arranged in the liquid storage pot. For the dialyzate regenerating device and the blood purifying
system provided by the invention, the recycling of the dialyzate can be realized, the use amount of dialyzate in the
dialysis process is greatly reduced, the
dialysis cost is reduced, the integral size of the
dialysis device is reduced, the carrying is convenient, and due to the
modular design, the
system can realize various functions.
