An electroencephalogram analysis device and analysis method for judging psychological state

Technical Field

The present invention relates to the technical field of psychological state, and in particular to an electroencephalogram (EEG) analysis device and an analysis method for judging psychological state.

Background Art

Mental state is one of the basic forms of psychological activities. It refers to the complete characteristics of psychological activities within a certain period of time. Such as attention, fatigue, tension, relaxation, sadness, joy, etc. It has the characteristics of both psychological process and individual psychological characteristics, and is both temporary and stable. It is the intermediary link between psychological process and individual psychological characteristics, and constitutes the background for the development of all psychological activities. Various phenomena of human psychological activities exist in the form of psychological state. Therefore, when understanding the psychological life of oneself or others, what is directly observed is the psychological state that exists in a certain situation. As an indicator for understanding the psychological activities of oneself or others, the psychological state has obvious direct reality.

The other side of the top of the base 1 is equipped with an electroencephalogram analyzer body 5. A cable protection component is arranged between the electroencephalogram analyzer body 5 and the housing 2. The bottom of the cable protection component is connected to the top of the base 1. A wire 6 is installed inside the cable protection component. The detection end of the electroencephalogram analyzer body 5 is connected to the inside of the detection helmet 4 through the wire 6. The 64-channel amplifier is composed of two 32-channel amplifiers and can be split into two 32-channel amplifiers for use. The electroencephalogram analyzer body 5 adopts a 64-lead active electrode cap and uses high-purity Ag/AgCl electrodes. It has a real-time impedance display function. The display light on the active electrode displays the impedance in three colors in real time. The user can monitor the contact between the electrode and the scalp in real time, and can maintain a stable contact between the scalp and the electrode during the 1.5-3 hours experimental time, ensuring the stability of the collected signal. Using different psychological theory tasks, different research objects, and different research techniques and methods, it is a platform for testing the complexity of the psychological theory problem itself, the brain area positioning of the psychological theory, and other aspects. Through the coordinated use of the electroencephalogram analyzer body 5, the wire 6 and the detection helmet 4, the patient's brain waves can be detected.

The second support mechanism is installed on both sides of the shell 2, both ends of the first support mechanism slide through the shell 2 and are connected to the second support mechanism, and the detection helmet 4 is installed at the bottom of the first support mechanism; the first support mechanism includes a sleeve 7, and a rod body 8 slides through the inside of the sleeve 7, and both ends of the rod body 8 slide and extend to the inside of the second support mechanism, and a screw rod 9 is threadedly connected to one side of the top of the sleeve 7, and the bottom of the screw rod 9 extends to the inside of the sleeve 7 and fits the surface of the rod body 8.
