Abstract:
1. A method of treating blood of a living body to perform hemodialysis on the living body, the method comprising the steps of: sensing the density of urine excreted by the living body and in response to the density of the urine withdrawing blood from the living body and causing the blood to flow through a treatment system; altering at least the density of the blood through the action of a second fluid as the blood flows through the treatment system; sensing at least the density and flow rate of the blood before the density thereof is altered by the second fluid, sensing at least the density and flow rate of the blood after the density thereof is altered by the second fluid, and sensing at least the density and flow rate of the second fluid; controlling at least one of the density and flow rate of the second fluid based on the sensed densities and flow rates in response to the density of the urine; and returning the blood to the living body.
