Claim 2:
3. The blood purification apparatus according to claim 1, further comprising:
an arterial-blood-circuit opening-closing unit provided in the arterial blood circuit and that is capable of arbitrarily opening or closing an arterial circuit flow route; and
a substitution-line opening-closing unit provided between the substitution line and the arterial blood circuit and that is capable of arbitrarily opening or closing a substitution-line flow route,
wherein the control unit executes the drug introduction mode by executing
a negative-pressure-generating step of generating a negative pressure in a portion of the arterial blood circuit by closing the substitution-line opening-closing unit and the arterial-blood-circuit opening-closing unit so that a negative pressure is generated in the arterial blood circuit by the blood pump moving the substitution fluid through the arterial blood circuit;
a suction step of suctioning the substitution fluid in the substitution line into the arterial blood circuit by opening the substitution-line opening-closing unit after the negative-pressure-generating step so that the blood pump moves the fluid into the arterial blood circuit; and
an introduction step of introducing the substitution fluid in the substitution line into the arterial blood circuit by activating the blood pump after the suction step, and
wherein the predetermined liquid drug infused from the infusion portion is suctioned or introduced into the blood circuit together with the substitution fluid in the suction step or the introduction step.
