PROBLEM TO BE SOLVED: To provide a centrifugal pump device high in the support rigidity of an impeller.
SOLUTION: The centrifugal blood pump device includes the impeller 10 disposed in a blood chamber 7, permanent magnets 15a, 15b disposed on one surface of the impeller 10 and arranged in a radial direction, permanent magnets 16a, 16b disposed on an inner wall of the blood chamber 7 and attracting the permanent magnets 15a, 15b, respectively, a permanent magnet 17 disposed on the other surface of the impeller 10, and a magnetic body 18 and a coil 20 disposed in a motor chamber 8 and driving and rotating the impeller 10 through a bulkhead 6. Dynamic pressure grooves 21, 22 are formed on the inner wall of the blood chamber 7 and the bulkhead 6 opposing the impeller 10, respectively. The rigidity of the impeller 10 in the radial direction is increased by the permanent magnets 15a, 15b, 16a, 16b.
