ABSTRACT:
An artificial kidney system comprises an artificial kidney forming container having an inlet blood port connectable with a patient's artery and an outlet blood port connectable with a patient's vein so that blood from the patient's artery can flow through the inlet port into the container, then through an inner space of the container and then through the outlet blood port into the patient's vein, the inner space of the container being filled with an adsorbent for removing harmful and toxic compounds from a stream of blood flowing in the inner space from the inlet blood port to the outlet blood port, the container being provided with a separate chamber formed inside the inner space and limited by a semi-permeable polymeric ultrafiltration-type membrane which allows water and dissolved small molecules to be transported from blood into the chamber, and suction element connectable with the separate chamber so that the water and the dissolved small molecules are transported from blood into the separate chamber and further outside of the container under the action of suction of the suction element.
