Dialysis system with enhanced features

A dialysis system comprising:

• a blood pump;
• a dialyzer in fluid communication with the blood pump;
• first and second dialysis fluid balance chambers each having (i) a fresh dialysis fluid compartment in fluid communication with the dialyzer and (ii) a spent dialysis fluid compartment;
• a fresh dialysis fluid pump in fluid communication with the fresh dialysis fluid compartments of the first and second balance chambers;
• a spent dialysis fluid pump in fluid communication with the dialyzer and the spent dialysis fluid compartments of the first and second balance chambers;
• and
• wherein
• (i) the fresh dialysis fluid compartment of the first balance chamber and the fresh dialysis fluid compartment of the second balance chamber each have a single port for (a) receiving dialysis fluid from the fresh dialysis fluid pump, and (b) delivering fresh dialysis fluid from the respective fresh dialysis fluid compartment, and
• (ii) the spent dialysis fluid compartment of the first balance chamber and the spent dialysis fluid compartment of the second balance chamber each have a single port for (a) receiving dialysis fluid from the spent dialysis fluid pump, and (b) delivering spent dialysis fluid from the respective spent dialysis fluid compartment.
