Description

rehabilitation wheelchair

technical field

The invention relates to the technical field of rehabilitation wheelchairs, in particular to rehabilitation wheelchairs.

Background technique

At present, the development of electric mobility-assisted rehabilitation wheelchairs has been relatively mature. People hope to give rehabilitation wheelchairs more functions to facilitate use. Chairs are chairs equipped with wheels that can help replace walking. They are divided into electric and manual folding wheelchairs. It is an important mobile tool for home rehabilitation of the wounded, the sick, and the disabled, turnover transportation, medical treatment, and outing activities. The wheelchair not only meets the needs of the physically disabled and people with reduced mobility, but more importantly, it is convenient for family members to move and take care of the sick. Patients use wheelchairs for physical exercise and social activities. Ordinary wheelchairs are generally composed of foldable frames, front and rear wheels, left and right knee pads and pedals, left and right detachable armrests, handle brakes, seats and other parts. Hand wheelchairs are used in ordinary wheelchairs. On the basis of wheelchairs, a hand-cranking device is added, and an electric wheelchair is added on the basis of ordinary wheelchairs, and an electronic assist system is added to reduce the physical exertion of users. For the elderly with limited mobility or patients with damaged waists who need exercise, wheelchairs are an important tool for rehabilitation. It is an important tool to enable the disabled to take care of themselves in life activities. It is not only a means of transportation for the physically disabled, but more importantly, it enables them to use wheelchairs to perform physical exercises and participate in social activities. Existing wheelchairs are mostly used Driven by a motor, due to the lack of an effective locking structure, when the wheelchair is stopped halfway or due to a lack of battery power when the wheelchair is traveling on a steep slope, it is easy to cause the wheelchair to fall back and slide, causing the user to fall and be injured. For people with mobility impairments, due to the long-term static state of the legs and lack of exercise, it is easy to cause poor blood circulation, which is not conducive to the recovery of the disease. If the massage is not available for a long time, it is easy to cause muscle atrophy or even necrosis of the legs due to lack of blood supply. cause irreparable losses.
