Perfusion apparatus and ventricular assist device

The embodiment of the utility model provides perfusion equipment and a ventricular assist device. The perfusion equipment comprises a perfusion structure, a suction structure and a filtering structure, the perfusion structure comprises a perfusion assembly and a first catheter connected to an outlet of the perfusion assembly, and the end, away from the perfusion assembly, of the first catheter is used for communicating with a perfusion inlet of the blood pump, so that perfusion liquid is conveyed to the blood pump through the perfusion assembly; the suction structure comprises a suction assembly and a second catheter connected to an inlet of the suction assembly, and the end, away from the suction assembly, of the second catheter is used for being communicated with a perfusion outlet of the blood pump, so that perfusion liquid in the blood pump can be sucked out through the suction assembly, and particles in the blood pump are brought out. Moreover, the filtering structure is arranged on the second liquid gui
