摘　　要：随着老龄化社会的发展进程,老年人摔倒问题已经成为影响老年人身体的重要因素。跌倒是老年人意外事故的第二大主因,中国每年因跌倒造成的直接医疗费用在50亿元以上,社会代价约为160~180亿元。根据老年人跌倒时的常见状态,研究了一种老年人摔倒防护装置,包含ESA吸能壳体、多室气囊、铝蜂窝缓冲管、检测系统、控制系统。检测系统中的三轴加速度传感器检测到跌倒信号后,控制系统激发铝蜂窝缓冲管弹出,实现瞬间复合防护。With the development of aging society,the problem of falling of the elderly has become an important factor affecting the health of the elderly.Falls are the second major cause of accidents among the elderly.The direct medical cost caused by falls in China is more than 5 billion yuan every year,and the social cost is about 16-18 billion yuan.According to the common state of the elderly falling,this paper studies a fall protection device for the elderly,including ESA energy absorption shell,multi chamber air bag,aluminum honeycomb buffer tube,detection system and control system.After the three-axis acceleration sensor in the detection system detects the fall signal,the control system excites the aluminum honeycomb buffer tube to pop up to realize instantaneous composite protection.
