technical field

The invention relates to the field of medical technology, in particular to a device for assisting semi-disabled elderly people to get out of bed seamlessly to perform indoor activities.

Background technique

my country has entered an aging society, and the rapidly growing number of the elderly has brought great challenges to the social security system, the elderly care service system and the elderly health support system. In 2016, the "Fourth China Urban and Rural Elderly Living Conditions Sampling Survey Results" released by the National Aging Office held that there are 40.63 million disabled and semi-disabled elderly people in my country, and some of them are about 30 million elderly people who take care of themselves. Disability is the loss or limitation of a person's ability to perform major activities or life in daily life. Partial disability is also known as semi-disability. The decline in physical function leads to difficulties or mild impairments in individual life functions. With the help of external forces or auxiliary devices, the basic daily life is solved, including eating, dressing, going to the toilet, Indoor activities, bathing, and going out for social activities.

Home care is a traditional old-age care model in my country. Due to the limited self-care ability of semi-disabled elderly people, basic daily activities need others or assistive devices to complete.
