Description

A multifunctional auxiliary wheelchair for getting in and out of bed

technical field

The utility model relates to a wheelchair, in particular to a multifunctional auxiliary wheelchair for getting on and off the bed.

Background technique

Due to the development and progress of modern medicine, human lifespan is gradually increasing, and the number of elderly people is increasing. However, the aging social structure has become a major challenge for all countries in the world. Due to the gradual degeneration of various organs of the elderly and neuromuscular atrophy, many elderly people need to use wheelchairs for indoor and outdoor activities in their lives.

Due to the inconvenience of movement, when the elderly go from bed to wheelchair or wheelchair to bed, they often need others to carry them into or out of bed, but adults weigh about 60kg, and it is difficult to manually move them. If there are no able-bodied young people at home If you wait by your side, this way of hugging is usually a huge project, and at the same time, the elderly are easily injured during the transfer process.

The rapid development of production technology has pushed the humanized design of products to a new stage. The mutual unification of "human-machine-environment" and the design concept of "human-centered" have become an important part of the design and life operation of the entire modern society. People's requirements for the comfort and safety of wheelchairs are also constantly urging designers to innovate. Various wheelchair beds and nursing chairs meet the needs of the elderly to a certain extent and improve the quality of life of the elderly. However, the wheelchair bed combines the wheelchair and the bed into one. The elderly can take a short nap on the wheelchair bed, but the space of the wheelchair bed is usually narrow. If a long-term deep sleep is required, the comfort is far less than that of a traditional bed, and the elderly can sleep well. Quality is greatly affected. Nursing chairs are often limited to the addition of functional modules such as assisting the elderly to eat, defecate, and so on. Looking at various types of wheelchairs on the existing market, none of them solve the problem of getting in and out of bed for the elderly. Therefore, it is of great practical significance to design a multi-functional assisted getting in and out of bed wheelchair, say goodbye to the way of getting in and out of bed by force, and assist the elderly to get in and out of bed comfortably.
