HEMODIALYSIS DEVICE

Abstract

A hemodialysis device including a replacement fluid passage between a dialysate circuit and a blood circuit, the dialysate circuit and the replacement fluid passage being respectively provided with first and second flow rate restriction devices. Also provided is a connection portion pressure sensor for measuring a pressure of a connection portion between a dialysate supply passage and the replacement fluid passage, and a vein-side pressure sensor for measuring a pressure of the blood circuit. A control device adjusts an opening degree of the second flow rate restriction device multiple times based on the measured pressure of the connection portion pressure sensor, and the measured pressure of the vein-side pressure sensor, for one round, being from when a supply compartment of a chamber provided to the dialysate circuit is filled with a fresh dialysate until all of the fresh dialysate in the supply compartment has been discharged.
