Abstract: A fluid perfusion apparatus includes: a suction conduit for suctioning a fluid from inside a living body; a suction source connected to the suction conduit and configured to suction the fluid at a first flow velocity via the suction conduit; a suction control apparatus connected to the suction conduit and configured to control a flow of the fluid suctioned via the suction conduit; and a control circuit configured to control the suction control apparatus. The control circuit performs control for reversing the flow of the fluid suctioned via inside the suction conduit by the suction control apparatus, to generate a backflow, after controlling suction at the first flow velocity by the suction source for a predetermined period of time and to cause the suction control apparatus to perform re-suction at a second flow velocity greater than the first flow velocity after continuing the backflow for the predetermined period of time.
