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。
In this paper, the medical pressure injector system controlled by the 8031 single-chip computer is studied. The system uses a single 8031 single-chip microcomputer as the host, and is composed of a minimum of hardware to realize the real-time control of the system. The integrated mechanical and electrical instrument structure of the system provides a new type of modern equipment for imaging medical diagnostics. After clinical verification, the device can quickly and uniformly inject contrast media and is suitable for dynamic CT scanning of any part. Exempt medical staff from unnecessary injuries caused by X-ray radiation, and greatly reduce labor intensity and improve work efficiency.
