摘　　要：目的:设计一种伤员辅助抬运及减振系统,以解决伤员后送抬运所产生的作业人员易疲劳、对伤员的颠簸冲击较大等问题。方法:伤员辅助抬运及减振系统包括抬运背带和抬运减振装置2个部分。抬运背带由腰带、肩带、胸带、粘接带和接合部件等组成,其中接合部件包括调节扣、大搭扣、小搭扣、连接扣和挂钩装置等;抬运减振装置采用“延长把手+吸振器”的技术形式,其中延长把手为刚性把手,吸振器上设置剪式导向机构。对该系统开展试验,记录抬运人员的作业时间,并分析系统的减振特性。结果:伤员辅助抬运及减振系统可延长担架抬运人员的作业时间,降低抬运担架的振动量,最大减振量为71.73%。结论:该系统具有低振动、低劳动强度等特点,适宜在道路条件较差时使用,可满足伤病员后送抬运需求。Objective To design an assisted patient conveying and vibration damping system to solve the problems of operator fatigue and patient bump during casualty evacuation.Methods The assisted patient conveying and vibration damping system was composed of several conveying straps and a vibration damping mechanism.The conveying straps were made up of a waist strap,two shoulder straps,a chest strap,adhesive straps and joint components,and the joint components included adjusting buckles,big buckles,small buckles,connecting buckles and hook mechanisms;the vibration damping mechanism adopted the technical form of extension handle combined with vibration absorber,in which the extension handle was made of rigid material and the vibration absorber was equipped with a scissor guiding mechanism.Tests were carried out on the system to record the operating time of the operators and to analyze the system's vibration damping characteristics.Results The system developed extended the operating time of the stretcher conveyers while reduced the vibration during casualty transport,with a maximum vibration reduction of 71.73%.Conclusion The system developed gains advantages in low vibration and low workload,and can be used for casualty conveying in poor road conditions.
