A handle device and an intelligent walking aid device

Technical field

The present invention relates to an intelligent rehabilitation auxiliary device, and in particular to a handle device and an intelligent walking aid device.

Background technique

At present, China's population aging is becoming increasingly severe. China's aging population has a very large number of elderly people. It is expected that by 2030, the proportion of people aged 60 and above will account for more than 20% of the total population, making it the country with the highest degree of aging in the world. . The rapid development of population aging has led to the urgent need to solve the problem of assisted living for the elderly. According to the results of the Second National Sample Survey of Disabled Persons, the total number of people with various types of disabilities in the country is 82.96 million, accounting for 6.34% of the total population. Among them, the number of people with disabilities aged 60 and above is 44.16 million, accounting for 53.24% of the total number of disabled people in the country. %. At the same time, due to the extreme shortage of nursing staff, disabled, semi-disabled and other people with movement disabilities have a great demand for assistive devices. Walking assistive devices including wheelchairs, walkers, etc. are the most basic and commonly used assistive devices for people with walking disabilities. .
