[0002] Blood cell separation is to use a machine to separate blood components from each other according to the difference in specific gravity. Usually, blood cell centrifugation is used. During the separation process, the vibration of the centrifuge cup on the rotating disc of the cell separator should be minimized, because the vibration of the blood centrifuge cup is easy to produce The aggregation of blood cells affects the activation index of blood cells, and at the same time affects the normal carrying capacity and hemodynamic stability of the patient's blood. Now the power transmission device of the blood cell separator generally uses a motor. In order to reduce shock, the connection between the motor and the fixed plate is generally Add springs, that is, at least three springs are used to connect the motor housing with the fixed plate to reduce the vibration of the rotating disk connected to the motor output shaft. Stable, poor blood cell separation effect
