  • Hemodialysis system
    Patent number: 9199024
    Abstract: A hemodialysis system includes a body fluid volume calculating unit, a dialysis condition input unit with which blood flow velocity and dialysis fluid flow velocity in hemodialysis treatment performed after specific hemodialysis treatment can be input and input values of the blood flow velocity and the dialysis fluid flow velocity can be adjusted, a dialysis dose calculating unit configured to calculate, when the blood flow velocity and the dialysis fluid flow velocity are input to the dialysis condition input unit, by analyzing a mathematical model concerning urea kinetics, a dialysis dose of the hemodialysis treatment from the input blood flow velocity and the input dialysis fluid flow velocity, a body fluid volume calculated by the body fluid volume calculating unit, and the like, and a dialysis dose display unit configured to display the hemodialysis dose calculated by the dialysis dose calculating unit.
