摘要
目的自行研制一种智能可调式下肢抬高系统,实现下肢抬高角度、频率的量化及可视化。方法依据临床下肢功能康复要求,确定大腿、小腿调节杆可调长度及屈髋、屈膝角度范围,进行动力元件的受力分析及临床安全性、疗效性观察。结果本装置整体外形小巧紧凑,可单独调节屈髋、屈膝、转踝的角度,屈髋、屈膝动力元件受力分析符合设计要求。初步观察显示本装置抬高患肢治疗2周后疼痛改善程度、关节功能评分、关节活动度及Harris评分均优于布朗氏架组,差异有统计学意义(P<0.05)。结论本智能可调式下肢抬高系统设计可满足临床使用要求,适用于不同身高病患,屈髋、屈膝角度范围大、精度高,值得进一步改良及临床推广。
Objective To develop an intelligent adjustable leg raising system which could realize the quantification and visualization of lower limbs＇ elevation angle and frequency. Methods We determined the pole adjustable length of thighs and cruses and the flexion angle range of hips and knees according to the requirements of clinical lower limb function rehabilitation, and made force analysis of hip＇s and knee＇s flexion motivation mechanism and clinical observation on its security and effectiveness. Results This device was small and compact in overall appearance, which could adjust the angle of the hips and knees bending and ankles turning alone. The force analysis of the hips and knees flexion power element was consistent with the design requirements. The preliminary studies showed the device could relieve pain, improve the range of motion and promote the rehabilitation, which was superior to that of the Brown Ska（P〈0.05）. Conclusion The intelligent adjustable leg raising system meets the requirements of clinical usage, which is suitable for different heights, and the flexion angle ranges of hips and knees are wide and in high accuracy, which is worth of being improved and generalized.
