Transcranial electrical stimulation therapeutic instrument based on adjustable parameter

Abstract

The invention provides a transcranial electrical stimulation therapeutic instrument based on adjustable parameter, the instrument comprises a micro-control unit (4), a user operating unit, a simulating electrode (3) and a current control circuit (6); the user operating unit transmits an operating signal of a user to the micro-control unit (4) to perform digital-to-analogue conversion processing, the micro-control unit (4) transmits a voltage signal corresponding to simulating waveform to the current control circuit (9), and the current control circuit (9) changes the simulating waveform and current intensity of the simulating electrode (3). According to the invention, the instrument is small in size and has good portability; the instrument has a good user operating button system and has advantages of quick response and good stability, the instrument also comprises a liquid crystal display which can display parametric variation in real time, so that the user has good human-computer interaction experience, the output of positive and negative waveforms can be realized, and the instrument can be made to be suitable for different users. In addition, the instrument also comprises a multi-level security detection system, so that the instrument can protect the users to the greatest extent.

Description

technical field [0001] The invention relates to the technical fields of small portable equipment and medical rehabilitation, and in particular relates to a transcranial electrical stimulation therapeutic instrument based on adjustable parameters. Background technique [0002] With the acceleration of the pace of life in modern society and the increase in people's life pressure, more and more people are suffering from neuropsychiatric diseases. Taking stroke as an example, stroke is the main cause of disability among middle-aged and elderly people. China is the hardest hit area for stroke, with about 3 million cases every year. With the improvement of medical level, although the fatality rate keeps decreasing, the disability rate is as high as 70% to 80%, which not only brings a heavy burden to the family and society, but also seriously affects the quality of life of patients. At present, the treatment of such neuropsychiatric diseases is mainly realized through drugs, artif...

AI Technical Summary

Problems solved by technology

[0004] 1) The stimulation mode is single, and only has the direct current stimulation mode, and cannot realize the alternating current stimulation and pseudo-stimulation modes;

[0005] 2) Although there is a skin resistance detection module mentioned in the literature, it only sends out an alarm when the resistance is too large, and does not stop the electrical stimulation in time on the hardware or software, which cannot protect the user well

[0007] 1) The stimulation system does not have a safety detection link, and cannot provide safety protection for the user in the event...
