Sleep therapy apparatus based on electroencephalogram biofeedback and control method thereof

Abstract

The invention relates to a sleep therapy apparatus based on electroencephalogram biofeedback, also called as a good sleep generator. The apparatus comprises an electroencephalogram electrode, an electroencephalogram signal amplifying and filtering circuit, an A / D (analog / digital) sampler, a measuring and controlling system based on a single chip microcomputer, a D / A (digital / analog) output circuit, a stimulating signal drive circuit, a system power supply and the like, wherein an electroencephalogram signal, the electroencephalogram electrode, the amplifying and filtering circuit, the A / D sampler, the measuring and controlling system, the D / A output circuit, the drive circuit and a stimulating electrode are orderly connected, and an analytical algorithm module and a database are connected with the measuring and controlling system. According to invention, the single chip microcomputer system is used as a measuring and controlling platform, and collection, amplification and analysis processing of the electroencephalogram signal are realized in combination with the electroencephalogram signal amplifying and filtering circuit and a stimulating wave signal database which are arranged at the front end and a stimulating signal generating and drive circuit arranged at the rear end; corresponding therapy mode, stimulating wave group and stimulating intensity are selected according to the characteristics of the brain waves; and at last a therapy scheme is input by a post-stage stimulating circuit so as to realize biofeedback type sleep therapy.

Description

technical field [0001] The invention relates to the field of sleep therapy, in particular to a sleep therapy device based on electroencephalogram biofeedback and a control method thereof. Background technique [0002] Since ancient times, human beings have dreamed of gaining insight into their own functions and autonomously regulating the internal functions of the body. In the past 40 years, people have been researching on the use of instruments to detect the body's own physiological information, and feed it back to the subjects through sight, hearing, touch, etc., to train humans to recognize such information, learn to consciously control their own psychophysiological activities, and achieve the adjustment of the body. Function, the purpose of exerting the potential of the human body. This is biofeedback technology. [0003] Sleep is an extremely important physiological function to maintain human life, just like water and food. Nowadays, the social competition is fierce,...
