Description

An overturning bed with the function of assisting getting up

technical field

The invention relates to a mechanical transmission device for assisting standing up, in particular to an overturning bed with the function of assisting standing up.

Background technique

Due to various disasters and diseases, the number of disabled people is increasing year by year. At the same time, as time goes by, the aging of the population continues to increase. The disabled and the elderly have different degrees of loss of ability, such as walking, standing up, vision, hands and language. In order to provide nursing beds with superior performance for the disabled and the elderly, a lot of research has been done on nursing beds abroad, so that the nursing beds have functions such as assisting in getting up. Nursing beds have also been studied in China, but compared with foreign countries in terms of technology and performance, there are relatively large deficiencies.

At present, there are many nursing beds in the domestic market, mainly manual nursing beds. When using such manual nursing beds, the process of lying down and getting up requires assistance from others, and it is very inconvenient to use when the disabled or the elderly use it alone. Therefore, it is possible to design an electric flip bed with the function of assisting to get up to help the handicapped and the elderly lie flat and get up.
