The implantable axial blood pump, driven by external electromagnet, is studied recently. It oscillats when it is running because of the elastic implanted environment and driving force disequilibrium, etc. In this paper, a model of single erythrocyte in vibrated flow field was built to simulate the deformation and force of the erythrocyte. By using the mechanical injury principle of blood in blood pump, we studied the injury of a single erythrocyte resulted from oscillating boundary flow field. The research results indicated that the shape of the erythrocyte, force and velocity field nearby, which are affected by oscillating boundary flow field, all cause injury to the erythrocyte. All the researches shown in the present paper are expected to provide theoretical foundation for lightening hemolysis by the blood pump.
