Method used

A detachable chair bed for nursing care has been designed, comprising a fixed bed section and a detachable chair section that can be joined together. Combined with an electric push rod and armrest assembly, it enables automatic adjustment for elderly people when changing positions such as lying down, sitting, and standing, reducing their dependence on caregivers.

Benefits of technology

It enables elderly people to independently complete movements when changing positions without the need for caregivers, reducing equipment costs and saving space. Its function is similar to a combination of an electric nursing bed and an electric wheelchair, improving the autonomy and safety of elderly people's activities.

The detachable chair part includes a chair frame and a support plate assembly. The support plate assembly includes an upper body support plate part, a lower body support plate part, and a lower leg support plate part that are hinged sequentially. When the upper body support plate part, lower body support plate part, and lower leg support plate part are connected in a straight line and the vertical difference between the connection direction and the horizontal direction is less than a predetermined value, the support plate assembly and the fixed bed part as a whole are used to support elderly people in a lying position. When the upper body support plate part, lower body support plate part, and lower leg support plate part are connected in a straight line and the deviation angle between the connection direction and the vertical plane is less than a predetermined angle, the support plate assembly is used to support elderly people in a standing position. When the upper body support plate part and the lower leg support plate part rotate in opposite directions relative to the lower body support plate part, the support plate assembly is used to support elderly people in a sitting position.
