In order to improve the accuracy and safety of blood test, the research of centrifugal mechanism in automatic blood group analysis system is proposed. According to the theoretical research of centrifugal microfluidic, the structure of microfluidic chip is designed; According to the requirements of blood centrifugation, the appropriate motor is selected, and the three-dimensional model of the centrifugal mechanism is established by using Solid Works software, and the structure of the centrifuge is determined; The success rate and average time were calculated by centrifugation test of microfluidic chip on automatic blood group analysis system. The rationality and validity of the centrifugal structure were verified.
