Description

Rehabilitation wheelchair for old people

Technical Field

The invention belongs to the technical field of wheelchairs, and relates to a rehabilitation wheelchair for the old.

Background

The wheelchair is an important moving tool which is provided with wheels and can help to replace a walking chair for home rehabilitation, turnover transportation, treatment and outgoing activities of wounded persons, sick persons and disabled persons, not only meets the needs of physically disabled persons and mobility-handicapped persons for riding instead of walking, but also is more important for facilitating the movement of family members and caring for patients, so that the patients can do physical exercises and participate in social activities by means of the wheelchair.

Various rehabilitation wheelchairs are disclosed at present, but the function of exercising upper limbs is single, and the situation that the fingers of the old people like a cerebral palsy patient are not flexible and difficult to hold the old people, so that the old people cannot exercise is rarely considered.

In a wheelchair for assisting four-limb rehabilitation disclosed in CN106994069A, a moving plate is arranged in a placing cavity at two sides of the wheelchair, a sliding block placed in a sliding groove is arranged below the moving plate, a pull rod with a handle is obliquely fixed at one end of the moving plate, and the handle is held by hands to pull back and lift the handle.

In the multifunctional rehabilitation wheelchair disclosed in CN207306810U, grooves with convex cross sections are formed in both sides of the wheelchair, two sliders and an elastic belt for connecting the two sliders are arranged in each groove, and the sliders are fixed by positioning holes in the grooves.

In the "wheelchair for upper limb rehabilitation training" disclosed in CN203885737U, an elastic rope is fixed on the backrest of the wheelchair, a pull ring is fixed at the other end of the elastic rope, and the pull ring is pulled by hand during exercise. The front of the wheelchair is provided with a shaking support, the shaking support is connected with a rotatable shaking handle, and the shaking handle is held by hands during exercise and can rotate around the shaking support by force.

The upper limb exercising device can be used for rehabilitation training only by being held by hands, and is difficult to exercise for the old who are difficult to hold things, and the upper limb exercising device is single in function and rarely used for exercising fingers and arms.

Therefore, the development of the multifunctional rehabilitation wheelchair for the old has very important significance.
