Lower limb functional rehabilitation device based on electrical stimulation induction

Abstract

The invention discloses a lower limb functional rehabilitation device based on electrical stimulation induction, and the device comprises a thigh sheath which comprises a near-end part and a far-end part, the near-end part and the far-end part are connected through a sheath support, and the near-end part and the far-end part are respectively provided with a stimulation electrode; the lower leg sheath is also provided with a stimulating electrode; and the pressure trigger sends out an electric signal when the pressure trigger is subjected to pressure change so as to control the stimulation electrodes at the thigh sheath and the shank sheath to generate electrical stimulation. In the stepping process of a patient, the muscle of the diseased leg is electrically stimulated to provide muscle coordinated contraction, the gait can be improved, muscle retraining can be promoted, disuse atrophy can be prevented or delayed, the joint movement range can be maintained or widened, and the local blood flow speed can be increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lower limb functional rehabilitation device induced by electrical stimulation. Background technique [0002] Upper motor nerve injury refers to a series of clinical symptoms caused by damage to the cortex, internal capsule, brainstem, and spinal cord of the brain. These clinical symptoms are characterized by paralysis of the entire limb, manifested as monoplegia, hemiplegia, or paraplegia. If the degree of paralysis is not severe, there will be no muscle atrophy. If the degree of paralysis is severe, there will be mild disuse. Muscular atrophy, resulting in signs of foot drop, that is, when the patient is sitting, the lower limbs hang naturally. If the foot is in plantar flexion and completely unable to actively dorsiflex and varus, it is foot drop. This symptom can also be seen in sciatic nerve palsy and peroneal nerve paralysis. Total nerve paralysis. Generally, foo...

AI Technical Summary

Problems solved by technology

[0003] Functional electrical stimulation uses low-frequency current pulses to stimulate muscles that have lost nerve control, causing muscle contraction, promoting nerve regeneration and recovery of conduction function, and helping the recovery of limb function. The existing functional electrical stimulation structure is relatively simple, only Can complete simple muscle stimulation actions, but cannot help the lower limbs to complete walking actions
