Adjustable electrical stimulation walking aid

Abstract

The invention belongs to the technical field of artificial intelligence medical equipment, and particularly relates to an adjustable electrical stimulation walking aid instrument. The adjustable electrical stimulation walking aid comprises an electrical stimulation host, and is characterized in that an electrical stimulation mainboard is arranged in the electrical stimulation host, the electrical stimulation mainboard is connected with an electrode patch, an electrical stimulation output module is arranged in the electrical stimulation mainboard, the electrical stimulation output module is composed of a waveform generation circuit and a constant current circuit, and the waveform generation circuit is connected with the constant current circuit. The waveform generation circuit is composed of an amplification circuit and a waveform synthesis circuit which are connected in series, and a gyroscope chip is arranged in the electrical stimulation mainboard. The method has the advantages that the frequency, the pulse width, the duty ratio and the rising and falling time of the stimulation pulse are controlled, and the appropriate stimulation pulse width can be selected according to actual needs. Secondly, the angle opportunity which cannot be reached when the legs of the patient are lifted is obtained through the sensor for stimulation judgment, treatment can be carried out best when stimulation is needed, and the better treatment effect is achieved.

Description

(1) Technical field [0001] The invention belongs to the technical field of artificial intelligence medical equipment, and in particular relates to an adjustable electric stimulation walking aid. (2) Background technology [0002] Functional electrical stimulation (FES) belongs to the category of neuromuscular electrical stimulation (NES), which uses a certain intensity of low-frequency pulse current to stimulate one or more groups of muscles through a preset program. Induce muscle movement or simulate normal voluntary movement to achieve the purpose of improving or restoring the function of the stimulated muscle or muscle group. The clinical application of this technology is in the field of rehabilitation such as motor recovery after stroke, assisting children with cerebral palsy to improve upper limb function, treating gait during walking in patients with incomplete spinal cord injury, and FES-based neural prosthetics to restore lost motor function to paraplegic individuals...

AI Technical Summary

Problems solved by technology

In the existing treatment for foot drop, the waveform frequency, pulse width and other parameters used by most walking aids are fixed, which is easy to cause habitual adaptation problems for patients after a period of treatment, thus reducing the effect of treatment

Moreover, most walking aids cannot distinguish the timing of stimulation during the treatment process, do not determine the critical value of pain and the critical value of therapeutic effect, and simply perform electrical stimulation, thus failing to achieve the purpose of treatment
