WIPO Patent Application WO/2023/236759
Kind Code:
A1
Abstract:
A blood pump (1) and a driving apparatus (20). The driving apparatus (20) comprises a housing assembly (100) and a rotating shaft (200). The housing assembly (100) is provided with a mounting hole (131). The rotating shaft (200) comprises a first shaft segment (210), and an arc-shaped convex surface (211) is formed circumferentially on the first shaft segment (210). At least a portion of the arc-shaped convex surface (211) is positioned within the mounting hole (131). An inflection point of the arc-shaped convex surface (211) is opposite to the wall of the mounting hole (131). At the inflection point, the gap between the arc-shaped convex surface (211) and the wall of the mounting hole (131) is minimized. When the first shaft segment (210) is in contact with the wall of the mounting hole (131), the inflection point is in contact with the wall of the mounting hole (131).
