摘　　要：提出了一种以ARM单片机为核心,控制伺服电机提供血泵压缩舒张动力的方案。该设计方案结构简单,控制精确,实时性好,运行稳定,噪音小,且可依据需要调节血泵的搏动率、流量和压缩比。This article introduces a new method using the servo motor which is controlled by ARM microcontroller to provide power for a pulsatile blood pump to beat. This method is featured with straightforward structure, accurate control, excellent timeliness, stable performance and small noise. And it can adjust the rate of beat, the rate of flow and the compression ratio according to actual demand.
