Slow-wave sleep enhancing system and slow-wave sleep monitoring method

Abstract

The invention provides a slow-wave sleep enhancing system and a slow-wave sleep monitoring method. The slow-wave sleep enhancing system comprises a brain electricity collecting part, an electrical stimulation part and a control host; the brain electricity collecting part comprises a brain-electricity-signal collecting electrode and a brain-electricity-signal detecting module; the brain-electricity-signal detecting module is used for magnifying, filtering and analog-digital conversion of brain-electricity signals collected by the brain-electricity-signal collecting electrode respectively, and then is used for outputting the processed brain-electricity signals to the control host; the control host monitors the sleep state of a user according to the received brain-electricity signals, and if the user is in the slow-wave sleep state, a stimulation instruction is output; the electrical stimulation part comprises an electrical-stimulation pulse generation module and an electrical stimulation electrode; the electrical-stimulation pulse generation module receives the stimulation instruction, and outputs a stimulation current according to the stimulation instruction, and the electrical stimulation electrode transmits the stimulation current to the scalp to control the cerebral cortex. According to the slow-wave sleep enhancing system and the slow-wave sleep monitoring method, it is detected that the user is stimulated when the user enters the slow-wave sleep, and brain-activity arrhythmia caused by user stimulation at other moments is avoided.

Description

technical field [0001] The invention relates to sleep monitoring and regulation technology, in particular to a slow-wave sleep enhancement system and a slow-wave sleep monitoring method. Background technique [0002] Sleep is a basic survival requirement for humans or animals. If sleep is insufficient or irregular, normal life will be affected. The brain is the organ most affected by sleep in the body. Long-term lack of sleep will affect people's intelligence, causing symptoms such as depression, anxiety, and forgetfulness. [0003] A number of experimental studies have found that sleep is crucial to the consolidation of memory. At present, there are two popular views. One view is that the way sleep improves memory is by blocking ongoing disturbing activities, such as mental activities and external sensory stimulation; another view is that sleep strengthens synaptic connections to consolidate memories. [0004] In the animal experimental research on sleep and memory, for e...

Problems solved by technology

[0010] Among the above-mentioned technologies and methods for consolidating and improving memory by regulating sleep, in the method of inducing audio files with right brain memory with the same brain wave frequency as the working state, although it is mentioned that there are no side effects, the δ produced during sleep Waves can hypnotize the brain, but the frequency of brain electricity is different in different periods of sleep. If the state of sleep is not monitored, if the audio signal played is not synchronized with the rhythm of the brain at this time, it will be counterproductive

The neurofeedback training instrument based on EEG signals quantitatively detects the immediate state of the brain, and guides users to consciously adjust the EEG rhythm wave. It is difficult to achieve the EEG rhythm wave only through the user itself without external stimulation intervention. adjust

[0011] The use of health care products or medicines can treat insomnia to some extent and promote users to fall asleep, but due to the complexity of the ingredients, the effect of a specific ingredient is unknown, making the effect unstable and accompanied by side effects

[0012] The device that uses electrical stimulation to treat insomnia only achieves the treatment of insomnia by giving the brain a certain intensity of electrical stimulation, and does not involve the aspect of consolidating memory through sleep
