多功能行动辅助椅Multifunctional mobility chair

技术领域technical field

本实用新型涉及老年人辅助器械技术领域,具体涉及一种多功能行动辅助椅。The utility model relates to the technical field of auxiliary equipment for the elderly, in particular to a multifunctional action auxiliary chair.

背景技术Background technique

参照国际标注衡量,中国自2000年起正式步入老龄化社会。大部分较高年龄老年人常常需要专人的看护和照顾,这样一方面使得老年人的生活质量在自由度上大为降低,另一方面需要高昂的花费和人力支出,为家庭带来沉重的负担。随着年龄的增加,老人日常生活安全隐患也逐渐增加。独居老人的安全受到多方面的威胁,而跌倒更是老人生命健康的隐形杀手,也是主要威胁来源。跌倒对普通人来说非常正常,但是对于老人来说则非常危险。据统计全球每年有超过2/3的老人遭受过跌倒,而其中一半以上老人都受到不同程度的损伤。According to international standards, China has officially entered an aging society since 2000. Most of the older elderly often need special care and care, which on the one hand greatly reduces the quality of life of the elderly in terms of freedom, and on the other hand requires high costs and labor expenditures, bringing a heavy burden to the family. . With the increase of age, the safety risks of the elderly in daily life also gradually increase. The safety of the elderly living alone is threatened in many ways, and falls are the invisible killer of the life and health of the elderly and the main source of threats. Falls are very normal for ordinary people, but very dangerous for the elderly. According to statistics, more than 2/3 of the elderly in the world suffer from falls every year, and more than half of them are injured to varying degrees.

随着人们生活水平的提高,助老服务行业也得以快速发展。目前市场上有许多适宜老年行走困难者行走与康复的器械,如有双拐、轮椅、带有扶手支架的助行器等。中国实用新型专利CN201810538508.5公开了一种老人用多功能安全助行装置,该装置结构简单,但稳定性不足,对于腿脚不方便的老人而言,使用的安全性得不到保障;如中国实用新型专利CN201521060208.9公开了一种多功能骨科助行器,但是这种助行器不带有轮子,使用这种助行器需要不断的提起该助行器,老人会感觉比较吃力;又如中国专利201310034245.1是一种外骨骼式助力助行机器人,其对于下肢残疾的人群比较适合,但对于大多数老年人来说,其穿戴不便,结构复杂,实用性不高。With the improvement of people's living standards, the elderly service industry has also developed rapidly. At present, there are many devices on the market that are suitable for walking and rehabilitation of elderly people with walking difficulties, such as crutches, wheelchairs, and walkers with armrests. Chinese utility model patent CN201810538508.5 discloses a multifunctional safety walking device for the elderly. The device has a simple structure but lacks stability. For the elderly with inconvenient legs and feet, the safety of use cannot be guaranteed; for example, China The utility model patent CN201521060208.9 discloses a multifunctional orthopedic walker, but this walker does not have wheels, and the use of this walker requires constant lifting of the walker, which makes the elderly feel more labored; For example, Chinese patent 201310034245.1 is an exoskeleton-assisted walking robot, which is suitable for people with lower limb disabilities, but for most elderly people, it is inconvenient to wear, has a complex structure, and is not very practical.

因此,为解决以上问题,需要一种多功能行动辅助椅,能够实现老人使用时的多种使用状态灵活切换,各种使用形态稳定性强、舒适性高,辅助老年使用者行走,站立,代步,如厕等功能,并且使用方便,没有繁复的穿戴程序,适用性强。Therefore, in order to solve the above problems, there is a need for a multi-functional mobility assist chair, which can realize flexible switching of various use states when the elderly use it, has strong stability and high comfort in various use forms, and assist the elderly users to walk, stand, and walk. , toilet and other functions, and easy to use, no complicated wearing procedures, strong applicability.
