Abstract: A blood dialyzing apparatus includes a blood dialyzing filter for dialyzing blood by using a pressure difference between the blood and a dialysis solution, and a supplying means for supplying the blood and the dialysis solution to the blood dialyzing filter in order to alternately generate a state where a blood pressure is higher than a dialysis solution pressure and a state where the dialysis solution pressure is higher than the blood pressure. The blood dialyzing apparatus dialyzes a large volume of blood in a short period of time without increasing the size of the blood dialyzing filter and simply controls the volume of the dialyzed blood by adjusting the supply pressures of the blood and the dialysis solution.

Abstract: The present invention relates to an apparatus for, after separating plasma from blood using a plasma separation filter, purifying the blood by discharging various kinds of toxic substances from the separated plasma using an anion exchange resin filter and a charcoal filter, and more particularly, to an apparatus for purifying blood configured to be capable of miniaturization and be conveniently used by installing the plasma separation filter, the anion exchange resin filter, and the charcoal filter in a housing.
