Patient rehabilitation wheelchair with adjustable wheel inclination angle

Abstract

The invention relates to a patient rehabilitation wheelchair with an adjustable wheel inclination angle, and belongs to the field of medical instruments. The patient rehabilitation wheelchair with the adjustable wheel inclination angle comprises two longitudinal beams which are fixedly connected through a cross beam, a seat is fixed on the cross beam, front fork frames are hinged below the front portions of the two longitudinal beams respectively, rear fork frames are hinged below the rear portions of the two longitudinal beams respectively, front wheels are installed at the lower ends of the front fork frames, and rear wheels are installed at the lower ends of the rear fork frames. The whole gravity center can be lowered during climbing and stair climbing, the attachment area of tires and steps can be increased in a deformation mode, it can be guaranteed that enough friction force exists between the tires and the steps during stair climbing, slipping is not likely to happen, meanwhile, the axle distance can be adjusted, the span is increased, stability is improved, backward turning is not likely to happen, safety is high, and the wheelchair is suitable for application and popularization.

Description

technical field [0001] The invention relates to a patient rehabilitation wheelchair with adjustable wheel inclination angle, which belongs to the field of medical equipment. Background technique [0002] Wheelchairs are chairs equipped with wheels that can help replace walking, and 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. [0003] In order to reduce the fatigue of patients, there are many electric wheelchairs available on the market. And along with the development of science and technology, there have been electric wheelchairs that ca...

AI Technical Summary

Problems solved by technology

The problem with this type of wheelchair is that the center of gravity of this type of wheelchair itself is relatively high, and its center of gravity will further increase when climbing stairs. A slight shaking of the patient's body may cause a large change in the overall center of gravity, which can easily cause the wheelchair to turn backwards and collapse. Rollover, the patient has no ability to move, and if there is no one to rescue the patient after the rollover, the patient's life will be in danger

The contact surface between the track and the stairs is very small, and it cannot be adjusted according to the actual ground conditions. The track is easy to slip, which endangers the patient's life safety

Also because of this, although this wheelchair can climb stairs, its reliability is not good, which is why this wheelchair cannot be promoted and implemented

The wheelchairs that are commonly used now, even electric wheelchairs, are very difficult to climb steps, requiring others to pull them up, which is very laborious
