Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a rehabilitation auxiliary self-care vehicle. Background Art

[0002] China is gradually entering an aging society. In addition, children are busy with work and do not have much time to take care of their relatives with limited mobility. For these people with limited mobility, there are often no rehabilitation assistance tools that are more suitable for their own use. Even if there are related fitness equipment, they will be limited by the venue or need the help of others, which makes it difficult for people with limited mobility to perform good rehabilitation assistance and self-care exercises. These people sit in wheelchairs or lie in bed for a long time, which may lead to muscle atrophy and gradually lose their ability to exercise. This is not conducive to recovery and will aggravate the condition. Therefore, for these patients with limited mobility, provide them with a rehabilitation assistance and self-care device;

[0003] After searching, a rehabilitation assisted self-care vehicle with a publication number of CN104721018A was disclosed, which includes a bottom U-shaped frame, on which four support rods extending upward are arranged, between which a first handrail and a second handrail are arranged, and wheels are arranged below the U-shaped frame. The rehabilitation assisted self-care vehicle of the present invention has a novel design and a simple structure, and provides a rehabilitation assistive device that can be used independently by people with limited mobility without the need for care from others, so that they can maintain necessary exercise, which is beneficial to their physical and mental health;

For example, the height of the existing rehabilitation assisted self-care vehicles is fixed, but the heights of different patients are different, so the existing rehabilitation assisted self-care vehicles cannot be used for patients of different heights and have certain limitations in use. In addition, the existing rehabilitation assisted self-care vehicles are moved by the action wheels set at the bottom. Although they can assist patients to move themselves, when patients stop to rest, they often rely on the assisted self-care vehicle due to illness, which makes the assisted self-care vehicle subject to force and is easy to move, which is not conducive to the rest of the patients and also affects the patients' staying.
