Foot-operated lower limb exoskeleton exercise rehabilitation wheelchair

Abstract

The invention provides a foot-operated lower limb exoskeleton exercise rehabilitation wheelchair. An exoskeleton mechanism provided with a driving degree of freedom and a plurality of driven degrees of freedom is installed on a wheelchair comprising pedals, when a user tread the wheelchair to travel, a customized rehabilitation training which achieve the switching from a complete driving mode of legs to a complete driven mode of legs is achieved, on one hand, when the user is physically inactive, i.e., when the user is completely lack of physical strength or has part of physical strength, the exoskeleton mechanism can provide all power or part of the power which drives the wheelchair to travel to help the user to move; on the other hand, under the condition that the user is full of physical strength, the exoskeleton mechanism can provide different resistance as needed to help the user fully exercise the lower limbs of the user. The most important characteristic of the foot-operated lower limb exoskeleton exercise rehabilitation wheelchair is that the characteristics of the exoskeleton mechanism and the wheelchair are fully utilized, the wheelchair can help the user to move and carry out scientific rehabilitation training to the lower limbs of a convalescent, and the wheelchair is simple and practical, and is suitable for popularization.

Description

technical field [0001] The invention relates to a wheelchair and belongs to the technical field of rehabilitation medicine. Background technique [0002] With the aging of the population and the gradual increase of patients with stroke and hemiplegia, the number of patients with lower limb weakness and paraplegia is gradually increasing, which brings a heavy burden to the family and society. Looking at most patients who temporarily lose consciousness in their lower limbs, it is possible to restore their limb function through scientific exercise rehabilitation activities; at the same time, for most wheelchair users, it may be due to lack of physical strength or partial loss of lower limb function. Inactivity can lead to muscle atrophy and even ulceration. [0003] Utility model patents CN203154111U and CN202458979U disclose a rehabilitation wheelchair for moving the lower limbs.

Problems solved by technology

Looking at most patients who temporarily lose consciousness in their lower limbs, it is possible to restore their limb function through scientific exercise rehabilitation activities; at the same time, for most wheelchair users, it may be due to lack of physical strength or partial loss of lower limb function. Inactivity, which can lead to muscle atrophy and even ulceration

[0003] Utility model patents CN203154111U and CN202458979U disclose a rehabilitation wheelchair for moving the lower limbs. The rear wheel and the shaft are linked. When the rear wheel rotates, the crankshaft rotates the pedals to make a reciprocating movement similar to walking to help the patient move the pedals. The lower limbs on the board; the wheelchair has no power assistance, and the rear wheel drives the user's lower limbs to move. When the user is not physically strong, other people are needed to provide help, which is not very economical.

At the same time, the training mode is relatively single, and it cannot provide rehabilitation training in different modes

[0004] Invention patent CN201010543205.6 discloses a sitting exoskeleton lower limb rehabilitation robot in the field of medical rehabilitation technology, which drives the patient's leg training through the motor drive in the lower limb rehabilitation mechanism. The training mode is divided into active and passive modes to meet the requirements of different patients' lower limbs. Rehabilitation requirements; the device does not take full advantage of the power assist to help the user walk
