A lower limb rehabilitation device mounted on a wheelchair

Abstract

The invention provides lower limb rehabilitation equipment loaded on a wheelchair. The lower limb rehabilitation equipment loaded on the wheelchair comprises a chair back mechanism, a chair seat mechanism, a lower limb mechanism, an armrest mechanism and a lifting movement mechanism. According to the chair seat mechanism, a motor pushes an S-shaped support frame, and inclined states of a chair back are optimally switched in an angle range of 90 degrees from a vertical state to a horizontal state by a crank block; the chair seat mechanism is a bearing component of the whole rehabilitation equipment, and is also a mounting base frame of a power device of the equipment; a hip joint, knee joints and ankle joints of the lower limb mechanism cooperatively implement motions of tracks such as a straight line, an arc and a gait under the driving effect of multiple motors; according to the armrest mechanism, a clamping and locking mechanism controls a rectangular folding guard bar consisting ofan armrest supporting rod and an armrest surface rod piece; and by the lifting movement mechanism, the rehabilitation wheelchair has a lifting function and a movement function. The lower limb rehabilitation equipment loaded on the wheelchair is designed according to rehabilitation demands of a rehabilitation patient in different periods, unglamorous rehabilitation training of the patient is fusedinto daily life, the autonomous living capacity of the patient is improved, and scientific and effective rehabilitation training is implemented.

Description

technical field [0001] The invention relates to the field of household medical rehabilitation equipment, more specifically, a lower limb rehabilitation equipment mounted on a wheelchair. Background technique [0002] According to the "China Stroke Prevention Report 2016", the prevalence of stroke in my country has increased from 0.40% in 1993 to 1.23% in 2013, and this number is still increasing. It is worth noting that central nervous system injuries such as stroke, brain or spinal cord can cause motor dysfunction in the lower limbs, which seriously threatens the health of patients and greatly reduces the quality of life of patients. A large number of studies have shown that given scientific and timely rehabilitation treatment to such patients, the limb motor function of the patient will be improved, and even most of the motor function will be restored. [0003] However, the current situation shows that traditional rehabilitation therapy is based on long-term qualitative o...

Problems solved by technology

[0004] At present, the existing lower limb rehabilitation equipment at home and abroad are mostly suspended walking rehabilitation systems, and a few bed-type lower limb rehabilitation training robots and seat-type structural rehabilitation systems, but these rehabilitation systems have a large structure and require specific rehabilitation places to be placed. , which puts forward requirements on the rehabilitation site, and greatly limits the rehabilitation time and space of the rehabilitation patients, and leads to long rehabilitation period, low efficiency and unsatisfactory effect
