Multifunctional auxiliary wheelchair convenient for old people to use
Technical Field
The invention relates to the field, in particular to a multifunctional auxiliary wheelchair convenient for old people to use.
Background
The wheelchair is a necessary product for the old with inconvenient legs and feet, the wheelchairs in the current market are various, the mechanical wheelchair with the highest market share is still a common mechanical wheelchair, the mechanical wheelchair is composed of a metal frame, wheels and a braking system, the mechanical wheelchair can be folded and carried, and the wheelchair can basically meet various outdoor and indoor requirements for people who just walk into the old to realize independent life. In addition, other various auxiliary functions are increasingly added to modern wheelchairs, such as a movable or detachable plate at the lower part of the wheelchair, and the wheelchair can be used for toileting under the assistance of family people, but the toileting on the wheelchair seems simple, so that the wheelchair is greatly inconvenient in terms of dressing and taking off clothes, and even if a bedpan is arranged below the wheelchair, the wheelchair has a function of chicken ribs, and few people can use the toileting function.
Therefore, the existing multifunctional auxiliary wheelchair has the prominent defects that the old people are very inconvenient to go to the toilet, the main reason is that the old people with inconvenient movement cannot easily get up from the wheelchair, so that the buttocks are difficult to leave the wheelchair, the trousers cannot be taken off for going to the toilet by themselves, and the old people who are not looking after cannot easily get up from the wheelchair, so that the old people can continuously sit on the wheelchair for too long time, and bedsores are easily caused. In addition, the backrest of the conventional multifunctional auxiliary wheelchair is mostly of a fixed structure, so that it is difficult for the old to get back, and when the old needs to move from the wheelchair to the bed, the backrest and the armrest of the wheelchair become obstacles, so that the old cannot easily move from the wheelchair to the bed by himself, and the use is inconvenient.
