How to help their normal lives with the aid at this stage has been a concern for family members and medical health care workers.

At present, the auxiliary apparatus for the disabled, semi-disabled or disabled people to move the body mainly has two technologies: the first wheelchair technology is that the wheelchair is a relatively suitable auxiliary tool for mild disability, but is not suitable for heavier people with half disability, disability or disability, and mainly needs a plurality of persons for getting on and off the wheelchair. Therefore, another auxiliary tool is needed, namely a second technology, namely a shifting machine technology, and the shifting machine is currently provided with three types, namely a mode of installing a hanging rail at the top of a house, using an electric hoist and a hanging bag to hoist a body and moving the body along a preset track. And secondly, hoisting and moving the body by adopting equipment such as a movable small crane, a sling and the like. Thirdly, the body is supported and moved by using the muscle of the armpit part of the human body and the scapula. The several ways solve the problem of body movement of the incapacitator to a certain extent, but are inconvenient to carry and can complete the displacement only by assistance of a plurality of medical staff or other people.

In recent years, some researches and researches on body movement assisting devices are carried out at home and abroad, and new products appear, which are mostly lack of multifunctionality and portable function in design.
