X射线造影用遥控自动注射装置

A remote control automatic-injection instrument for X-ray radiography

本文介绍一种利用红外和单片机技术实现的X射线遥控自动注射装置。由于在系统中采用编码及载波调制的方法,保证了系统的可靠性。该装置用于逆行肾盂、尿道、胆管、窦道等造影,保护从事X射线造影的医护人员免受X射线损害。

An auto-injection instrument with X-ray remote control is presented. The system is developed by using infrared technique and single chip microcomputer. The methods of code and carrier modulation are adopted to ensure reliability of the system. The instrument is suitable for retrograde pyeolography, and for radiography of urethra, bile duct and sinus tract, and protects the medical staff making radiography from the injury of X-ray.
