摘　　要：目的:研制用于训练瘫痪患者(包括截瘫、偏瘫和四肢瘫)肢体功能恢复的医用智能起立床。方法:以瑞萨16位单片机R8C/25为控制器,采用丹麦Linak31直线传动器驱动床体,用数码管显示治疗处方、起立床角度、治疗时间和播放乐曲,并增加了音乐播放功能。结果:医用智能起立床能够非常稳定地工作,床体的角度能得到很好的控制,误差只有1°角;数码管的显示稳定;MP3播放模块能准确地控制播放第几首音乐;后备电源在断市电的时候能稳定及时地为系统提供工作用电。结论:医用智能起立床已在生物医学领域成功应用于临床。Objective To develop a medical tilting-table for recovery training of paralysis patients （including paraplegia, hemiplegia and quadriplegia）. Methods Renesas 16-bit microcontroller, R8C/25, was used as controller. Danish Linak31 was used to drive the bed. Nixie tube was used to display prescription, angle of tilting table, treating time and music list. Results It worked stable with well-controlled angle. The error was only 1°. The display of nixie tube was good and stable. MP3 played well. Back-up power could provide power supply timely and stably in power failure. Conclusion Medical tilting-table has been successfully applied in clinic.
