Abstract
A blood purification apparatus (1A) comprises: a dialysate supply unit that prepares a dialysate from at least first and second stock solutions; a first container unit (110) and a first holder unit; and a second container unit (120) and a second holder unit. The first container unit (110) contains a first raw material powder which is a raw material powder of the first stock solution, and the first raw material powder contains at least two of a calcium salt, a magnesium salt, a potassium salt, and a sodium salt as main components. The second container unit (120) contains a second raw material powder which is a raw material powder of the second stock solution, and the second raw material powder contains sodium hydrogen carbonate as a main component. The first holder unit constitutes a first flow path through which a dissolution solution is introduced into the first container unit (110) and through which the first stock solution, which contains the first raw material powder dissolved in the dissolution solution, is delivered to the dialysate supply unit. The second holder unit constitutes a second flow path through which a dissolution solution is introduced into the second container unit (120) and through which the second stock solution, which contains the second raw material powder dissolved in the dissolution solution, is delivered to the dialysate supply unit.
