Intelligent power-assisted electric stimulation system

Abstract

The invention discloses an intelligent power-assisted electric stimulation system. The system comprises a functional main board and terminal equipment; the functional main board comprises a stimulation electrode, a stimulation module, a main control module, a collection electrode and a collection module, the stimulation electrode and the collection electrode are connected with an action part separately, and the main control module controls the stimulation electrode to output stimulation current through the stimulation module; the main control module obtains a signal collected by the collectionelectrode through the collection module, processes the signal and feeds the signal back to the stimulation module, and the stimulation current is output through the stimulation electrode. By means ofthe system, the magnitude of the myoelectric signal is collected according to high-speed and high-precision myoelectric sampling, the system self-adaptively gives corresponding strong and weak electrical stimulation, the willingness and requirement of a user for subjective motion are completely reflected in real time, and the user is helped to complete the action which he / she wants to complete.

Description

technical field [0001] The invention belongs to the field of medical electronics and relates to an intelligent power-assisted electrical stimulation system. Background technique [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. [0003] Existing functional electrical stimulation mainly includes passive functional electrical stimulation and triggered functional electrical stimulation. Passive functional electrical stimulation is to pre-set the stimulation current intensity and stimulation time. During the stimulation process, the stimulation current remains unchanged, and the stimulation treatment in the interval is...

AI Technical Summary

Problems solved by technology

Passive functional electrical stimulation is to pre-set the stimulation current intensity and stimulation time. During the stimulation process, the stimulation current remains unchanged, and the stimulation treatment in the interval is stopped. A period of time is customized for this treatment. The user accepts the treatment passively, without self-consciousness and active contraction throughout , action; trigger-type functional electrical stimulation adds myoelectric feedback on the basis of passive functional electrical stimulation. When the value of the feedback electrical signal exceeds the previously predetermined threshold value, electrical stimulation starts. When the stimulation current and stimulation time are stimulated according to the previous predetermined value, the user actively Participate in passive training, the stimulation current and stimulation time do not change during the stimulation process, and cannot reflect the user's subjective consciousness after triggering

[0004] Generally speaking, after the existing functional electrical stimulation is triggered, the electrical stimulation has nothing to do with the user's subjective will, and the stimulation operates according to the previously set mode, which is not in sync with the action the user wants to do, and the effect is not obvious , improper operation may even have a counterproductive effect
