Apparatus for preparing dialysate solutions

An apparatus for preparing dialysate solution comprising:

• a chamber, an inside of which is divided into a first compartment, a second compartment and a third compartment by movable partitions;
• a first dissolving solution supply line for supplying a dissolving solution into the first compartment of the chamber;
• a dialysate solution preparing line connecting the first compartment and the third compartment of the chamber;
• a solution tank connected to the first compartment and a transporting pump connected to the third compartment and both of which are provided in the dialysate solution preparing line, the solution tank being connected to the transporting pump;
• powder supply means provided above the solution tank;
• a dialysate solution transporting line for transporting a dialysate solution filled in the third compartment to a point of use;
• a circulating line connecting the dialysate solution transporting line with the dialysate solution preparing line between the solution tank and the transporting pump;
• a by-pass line for bypassing the solution tank and connecting the first compartment with the third compartment via the circulating line;
• means for charging and discharging a liquid to and from the second compartment of the chamber;
• wherein the quantity of dissolving solution to be supplied to the first compartment and the quantity of dialysate solution to be transported to the third compartment can be adjusted by charging and discharging the liquid to and from the second compartment of said chamber.
