Research of Multi-Functional Lumbar and Cervical Spine Electric Rehabilitation Traction Bed Intelligent Control System

摘要: 针对传统腰颈椎牵引设备牵引方式单一，不能满足病患不同的症状治疗，本文提出一种多功能腰颈椎电动康复牵引床智能控制系统。采用闭环控制方式，在单片机的控制下接收触摸屏输入和拉力传感器输入，驱动电机带动牵引机构实现牵引活动，同时将输入参数和运行状态输出显示，是一种数字式触摸屏用户界面的牵引装置。用户可以根据需要设定具有保持、休息和治疗时间的静态(持续)、间断和循环牵引功能，并能够用坐标图实时显示牵引力工作状态。通过设定持续时间和拉力大小，持续牵引床体，使颈、腰椎处于被牵引的状态，从而实现对腰颈椎疾病的治疗。实验结果表明：该牵引装置不仅具有较好动态响应性能、实现牵引力的精准控制、良好的人机交互、患者信息存储和动态显示牵引力大小，而且具有较好的治疗效果，牵引过程更加平稳、安全、可靠。

Abstract: In view of a single traction way of the traditional lumbar and cervical spine traction equipment, the treatment of patients with different symptoms cannot be satisfied, and the intelligent control system of multi-functional lumbar and cervical spine electric rehabilitation traction bed was put forward. The system adopts the closed-loop control mode, receives the input of touch screen and tension sensor under the control of the microcontroller, and achieves traction activities by the traction drive mechanism with motor. The input parameters and operating status are displayed at the same time, and it is a traction device with digital touch screen user interface. The user can set the static (continuous), intermittent and cyclic traction functions which have hold time, rest time and treatment time based on needs, and can display the traction working status with the coordinate map in real time. By setting the duration time and the size of tension, lumbar and cervical spines are in the traction state by continuous traction bed, in order to achieve the treatment of lumbar and cervical spine disease. The experimental results have shown that the traction device has not only good dynamic response performance, precise control of traction, good human-computer interaction, patient information storage and dynamic traction, but also has good therapeutic effect, and the traction process is more stable, safe and reliable.
