气动技术在下肢联动康复训练仪上的应用

摘要

Objective In order to eliminate the sense of motion caused by the lower limb rehabilitation training instru-menusingelectric drive, in this paper,we research and design an application of pneumatic drive for lower limb rehabilitation training instrument, to make the patient's rehabilitation training more comfortable, and providerehabilitation modalitycombi-nation of active and passive to enhance the consciousness of active rehabilitation in patients with hemiplegia. Methods Through the three aspects design of mechanical structure, pneumatic driving force, linkage motion mode control,to make sure that pneumatic technology is applied to the rehabilitation training instrument of the lower limb, and through micro pneumatic driving experimentverify the feasibility of the design. Results Experimental resultsshowpneumatic driving force can be used instead of electric driving force, and the driving load rate βis about 67.3%. Conclusion The uniform speed re-habilitation exerciseis transformed intovariable speed rehabilitation exercise,make feeling ofthe rehabilitation exercise be-come more comfortable.%目的：为消除下肢康复训练仪因电动驱动机构引起的运动机械感，该研究将气动技术应用于下肢康复训练仪，使患者的康复训练更为舒适，并提供主被动相结合的康复训练模式，增强偏瘫患者的主动康复意识。方法通过机械结构、气动驱动力、联动运动模式控制三方面的研究，来完成气动技术应用于下肢康复训练仪的整体设计，并通过微型气动驱动实验来验证设计的可行性。结果微型实验证明气动驱动力可代替电动驱动力完成康复训练所需的驱动力，得出驱动负载率β约为67.3%。结论在气动技术的应用下，康复运动由匀速运动转为变速率运动，运动更具柔顺性。
