摘　　要：本文研究了8031单片机控制的医用压力注射器系统，系统采用一片8031单片机作为主机，以最少的硬件组成，实现了系统的实时控制。系统所具有的机电仪一体化结构为影像医学诊断提供了一种新型的现代化器械，经临床验证，该装置能快速、均衡地注射造影剂，适用于任何部位的增强CT动态扫描检查，不仅可免除医务人员因X线照射所造成的不必要的伤害，而且可大大减轻劳动强度，提高工作效率。This paper studies the propulsive force of injector system controlled by 8031 single-chip microcomputer for Medical use By using one 8031 single-chip microcomputer as a microprocessor, the minimal autometiccontrol system is constructed, which turns real-time control into reality. This product is a modern appliance usedin diagnostic imaging medicine, in design of which the advanced instrument and electrical machinery are integratedinto a unified structure. The clinic data demonstrate that the contrast medium can be injected to patients withrapidly and evenly. dynamic CT Scanning can be intensified at any site of the body. x-ray dose exposed and lobourintensity to the operator can be decreased greatly, raise working efficiency.
