摘　　要：目的为解决现有髋关节持续被动运动(Continuous Passive Motion,CPM)仪无法满足患者居家康复需求的问题,研制一款新型家用下肢康复CPM设备。方法本设备由主机和髋关节固定带组成。主机控制髋关节固定带进行周期运动,实现患者下肢关节反复衩动屈伸。根据医疗器械的相关标准进行样机的设计和制作,并对其角度参数、角速度、静载荷、噪声、运动周期等参数和安全性能进行验证。结果该设备可使患儿髋臼骨与股骨头在60°~90°范围内,以4~8°/s的角速度进行下肢关节反复衩动屈伸。设备的结构设计与功能参数均达到了设计目标,符合相关标准要求。结论本文研制的家用下肢康复CPM设备可满足患儿居家康复的需求。Objective To address the issue of existing hip joint continuous passive motion(CPM)devices failing to meet the home rehabilitation needs of patients,to develope a new type of home-use lower limb rehabilitation CPM device.Methods A main unit and a hip joint fixation strap were made up of the device.The hip joint fixation strap was controlled by the main unit to perform cyclic motion,facilitating the repetitive flexion and extension of patient’s lower limb joints.The prototype was designed and manufactured according to relevant medical device standards,and its angle parameters,angular velocity,static load,noise,motion cycle,and safety performance were verified.Results The device enabled the acetabulum and femoral head of pediatric patients to undergo repeated flexion and extension within the range of 60°~90°at an angular velocity of 4~8°/s.The structural design and functional parameters of the device met the design objectives and complied with relevant standards.Conclusion The home-use lower limb rehabilitation CPM device developed in this study can meet the home rehabilitation needs of pediatric patients.
