Description

Walking rehabilitation assisting device for patient with lower limb weakness

Technical Field

The invention relates to the technical field of medical rehabilitation equipment, in particular to a walking rehabilitation assisting device for a patient with lower limb weakness.

Background

In clinical rehabilitation, in early and acute rehabilitation stages of patients with stroke, cerebral palsy and the like, the cerebral nervous system interrupted and disordered due to brain tissue injury is often required to be awakened and remodeled through joint movement, and meanwhile, the muscle strength can be improved through the joint movement, and other diseases such as muscle atrophy, pressure sores generated on limbs and the like can be avoided. In clinical rehabilitation departments in the related art, most of the rehabilitation doctors manually help patients to perform corresponding rehabilitation actions. Because the patient can not provide active power for movement in the period of flaccid paralysis, the patient needs to be helped by the power of a rehabilitee at the moment, and the labor and time cost is greatly wasted. Because the daily recovery amount of each rehabilitee is limited, the demand of brain tissue injury patients and orthopedic injury patients for rapid growth cannot be met. And the rehabilitation mode cannot be well controlled by artificially performing acute-phase rehabilitation training, such as effective switching of passive, active and impedance modes.

At present, although some equipment capable of helping patients to recover lower limbs is available in the market, most equipment still occupies the majority of the equipment which is recovered manually, the training method using the auxiliary device is low in safety, special personnel are needed to attend the equipment, power assistance is needed to be provided from the outside, and manpower and energy cost are wasted.
