CENTRIFUGAL PUMP AND METHOD FOR MANUFACTURING SAME

摘要

A centrifugal pump is provided with: a pump chamber (24); a blood ingress port (25) through which blood Q flows in, the blood ingress port (25) communicating with the pump chamber (24); a housing (2) having a blood egress port (26) through which blood Q that has flowed in from the blood ingress port (25) flows out, the housing (2) communicating with the pump chamber (24); a rotor (3) rotatably housed in the pump chamber (24) and functioning as a centrifugal-force-imparting member for imparting centrifugal force to the blood Q by rotating; and a support mechanism (4) for rotatably supporting the rotor (3) in the housing (2). The support mechanism (4) has a rod-shaped shaft member (41) and is disposed at the center of rotation of the rotor (3), the support mechanism (4) being integrally formed with the shaft member (41) and rotator (3).
