ABSTRACT:
An automatic priming method in which an arterial-side chamber is maintained in a normal position during priming, as in a case of dialysis treatment, and in which forward and backward rotations of a blood pump are employed, and a speed of rotation, in particular, backward rotation, is adjusted to be low, so that air or the like is reliably prevented from entering a dialyzer. The priming method for use in a blood purification circuit in which priming is conducted by supplying physiological saline into a circulation circuit formed by connecting an arterial blood circuit with a venous blood circuit includes filling the venous blood circuit with a priming solution (physiological saline), discharging the priming solution for cleaning the arterial blood circuit, conducting a treatment in a direction opposite to the overflow step, which may be followed by a forward direction re-circulation step, and re-circulating in a forward direction.
