The utility model comprises a square-wave generator, a frequency converter circuit, a timing circuit, a wave and frequency transform circuit, a power amplifier, a coupling coil, an indicating circuit, and a power circuit.

Description

The device of simulation sleeping brain wave

This utility model is the brain wave of a kind of normal person of simulation when sleeping, and induces the brain wave of brain synchronous with it, the sleep rhythm of correcting disorderly, thus reach the device that improves sleep quality, belong to the technical field of daily living article.

Brain to the people carries out hypnosis, generally adopt the method for medicine to carry out, and the life-time service medicine not only makes the people develop immunity to drugs, so that drug dose constantly increases, and human body is also had side effects, and will constantly consume financial resources.Although people have recognized the drawback of using medicine, because neither one can replace the method or the product of medicine, therefore people still carry out hypnosis at the pharmaceutical methods of continuing to use in decades for a long time.Also someone's method that adopts physics that begins one's study solves the device of sleep, its major programme is to adopt little galvanism to impel people's brain to enter sleep state as early as possible, but there is certain danger in this method, no matter be because instrument breaks down or the position of galvanism is incorrect, beyond thought injury is brought to user in the capital, and therefore this scheme never is implemented so far.Another kind of emulation wave and the raindrop sound of adopting carries out hypnosis to the people, also fails to be implemented because of weak effect.

The purpose of this utility model provides a kind of without medicine, and brain is not produced stimulation, and only to the device of the inducing simulation sleeping brain wave of the brain wave of brain.

The device of this utility model simulation sleeping brain wave mainly is made up of square-wave generator, freq converting circuit, timing circuit, waveform and frequency-conversion circuit, power amplifier, coupling coil, indicating circuit, power circuit.Freq converting circuit input and timing circuit outfan join, output termination square-wave generator input, square-wave generator outfan and waveform and frequency-conversion circuit input and indicating circuit join, power amplifier input and waveform and frequency-conversion circuit outfan join, outfan and coupling coil join, coupling coil other end ground connection.

Its operation principle is as follows:

The effect of square-wave generator is to produce the point of required α, θ, δ ripple square wave frequently, and the effect of freq converting circuit is controlling party wave producer α, θ, the conversion of δ wave frequency, and the effect of timing circuit is the working time of control α, θ, δ ripple.More than three kinds of circuit form by single-chip microcomputer IC1 (also available vibration, regularly, counting, switch integrated circuit finish) and peripheral cell, C2, C3, JT form clock oscillator, C1, R1 form electrify restoration circuit, C6, C7 are electric source filter circuit, outfan 11 feet of IC1 connect the light emitting diode of indicating circuit, the square wave frequency of 12 to 16 its outputs of foot reduces by half successively, and the square wave frequency of 16 feet output equals α, θ, δ wave frequency, the corresponding input of welding wave and frequency-conversion circuit 4.The effect of waveform and frequency-conversion circuit is that the square-wave signal of IC1 output is transformed into the simulation brain wave identical with frequency with the waveform of human brain α, θ, δ ripple, this circuit is made up of IC 2, R2, R3, R4, R5, R6, C4, the input of output termination power amplifier, the effect of power amplifier is the power amplification of finishing the simulation brain wave, drive coupling coil T at last, this circuit is made up of audion BG, C5, R7, R8 and coupling coil T.The effect on indication road is that indication simulation brain wave is operated in slow wave or fast wave state, and this circuit is made up of R9 and light emitting diode D.Coupling coil is the solenoid of a flat, produces the electromagnetic field of simulation brain wave.

Confirm that after deliberation sleep physiology mechanism is that normal person's nighttime sleep begins with S sleep (SWS), approximately entered fast quick-action eye sleep (REM) through 90 minutes, REM approximately continues 20-30 minute, enters the SWS sleep again, this process 4-5 time repeatedly, more near the later stage, the time that REM continues is longer.The brain wave of S sleep is the light moderate θ sleep ripple of 4-7 hertz and the δ deep sleep ripple of 0.5-3 hertz, and the brain wave when fast quick-action eye is slept is the α ripple of 8-13 hertz.When there is the simulation brain wave electric field of similar brain wave the brain outside, tend to induce brain wave synchronous with extraneous simulation brain wave electric field, thereby sleep state that can the mediator.According to this principle, this device can produce a kind of device of brainwave activity rule electric field of simulation normal person brain sleep of high emulation.Promptly produce α, θ, the δ sleeping brain wave of emulation, lure imported big brain wave synchronous, with the effect of the sleep rhythm that reaches the mediator with it.

Advantage of the present utility model is:

1, because this device can produce α, θ, the δ ripple of anthropomorphic dummy's brain, the coupling coil that produces electric field is placed on by people's the brain, just can play the brain wave effect synchronous with it that lures in the imported brain, mediator's sleep rhythm is to improve people's sleep quality.

2, this device is induced the brain wave in people's brain synchronous with it, rather than certain electromagnetic field is acted on human body by force owing to only produce the brain wave of emulation, thus to human body without any injury, more without any side effect.

3, easy to use, cost is low.Because volume is little, user is gone out and can conveniently be carried, and power consumption is little, and available battery powered is safe and reliable, and it is low to add cost, and the people of sleep disorder is arranged, but general people one of staff all.
