Artificial kidney

Claim 1

An artificial kidney system, comprising 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 said inlet port into said container, then through an inner space of said container and then through said outlet blood port into the patient's vein, said inner space of said container being filled with an adsorbent for removing harmful and toxic compounds from a stream of blood flowing in said inner space from said inlet blood port to said outlet blood port, said container being provided with a separate chamber formed inside said 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 said chamber; suction means connected with said separate chamber so that the water and the dissolved small molecules are transported from blood into said separate chamber and further outside of said container under the action of suction of said suction means, said container having a urine outlet communicated with said separate chamber; and artificial ureter forming tube means connecting said urine outlet of said container with said suction means so that urine with the water and dissolved small molecules is withdrawn from said separate chamber through said artificial ureter forming tube means, said suction means including a vacuum providing vessel, said artificial ureter tube means having one end connected with said urine outlet port and another end introduced into an interior of said vacuum vessel, said vacuum vessel being formed as an elastic vessel which is squeezable by a patient and restorable under elastic action of said vessel so as to form vacuum in its interior.
