Embodiment Construction

[0028] Portable brain function biofeedback instrument based on embedded system (such as figure 1 , Figure 9 Shown): The system includes an EEG detection system (hardware) for detecting the EEG signals of the human body (children), and an analysis training system (software), so as to quantitatively and objectively evaluate the attention level of ADHD patients, To help ADHD patients use biofeedback to self-regulate and improve attention training; the biofeedback training system includes some human-computer interaction training modules, which are also helpful to help the subjects improve memory and reaction speed. See the attached picture for the device model. Figure 9 High-performance preamplifier and common-mode drive circuit: INA121 and INA128 form the preamplifier, Rg1 and Rg2 adjust the magnification; R1 and R2 pick up the common-mode signal, and form a common-mode drive with OP37G. A preamplifier and a common-mode drive circuit are used: the input end of the preamplifie...

Abstract

The invention discloses a portable brain function biofeedback instrument, comprising a calculation analysis module, a human-computer interaction module, a storage module and a control module which are sequentially connected with each other. The calculation analysis module consists of an electroencephalophone measurement lead of an input sensor connecting with a human body, an amplifying and frequency-selecting module, a lead drop-off automatic detection module, a screen drive and right leg drive module, an A/D sampling and converting module and a DSP; the human-computer interaction module consists of a touch screen and a speaker; the storage module consists of an standard deviation (SD) card; and the control module consists of an embedded ARM micro-processor. The calculation analysis module realizes extraction of alpha wave, beta wave and theta wave of a characteristic electroencephalophone component to give an electroencephalophone active mode; and the storage module realizes storage of data and an analysis result. The portable brain function biofeedback instrument feeds back the electroencephalophone information to a trainee through detecting the electroencephalophone information by an engineering technology, and generates the lasting effect through a repeated training to enable the brain to develop towards a normal and healthy level. An electroencephalophone biofeedback therapy can further and fully mobilize the internal potential of the trainee so that the trainee actively participates in the treatment.

Description

technical field [0001] The invention relates to brain electric signal detection and biofeedback technology. Background technique [0002] Attention disorder hyperactivity syndrome (ADHD) is the most common phenomenon or state of school-age children (it can even be said to be one of the mental diseases). . About 5% to 15% of children suffer from ADHD, and 20% of them suffer from symptoms into adulthood. Therefore, it was proposed that treatment is needed, and multimodal treatment is advocated in treatment, with central stimulants as the mainstay. However, the drug only has a temporary effect on some cases and has relatively large side effects and poor compliance. With the development of modern EEG biofeedback theory and technology, workstation-type EEG biofeedback systems for human brain detection and feedback have been developed in developed countries. However, the current international brain function biofeedback instruments mainly rely on workstations or PCs, which are ...
