As shown in FIGS. 1 to 4, the present invention provides a sleep apparatus.
In one embodiment, as shown in fig. 1, the sleep meter includes a host 1 and a magnetic coil 2 electrically connected to the host 1. The host 1 is used for sending a pulse signal and inputting the pulse signal into the magnetic coil 2, the magnetic coil 2 generates a corresponding time-varying magnetic field according to the received pulse signal and couples the magnetic field to a brain sleep center of a patient with sleep disorder, so that the sleep process of the patient is adjusted and induced conveniently, and the functional magnetic coil for promoting sleep or waking up is realized. The main machine 1 and the magnetic coil 2 are of a separated structure, and when the magnetic pillow is used, the magnetic coil 2 is placed under the pillow of a sleep disorder patient, so that the sleep disorder patient is prevented from directly contacting the magnetic coil 2 to cause potential safety hazards; namely, the magnetic coil 2 converts the time-varying magnetic field into a time-varying magnetic field, and couples (in a non-contact way) the time-varying magnetic field to the brain sleep center of the patient with sleep disorder, so as to realize the functions of guiding falling asleep and realizing timed awakening, thereby achieving the purposes of treating insomnia and improving sleep quality.
Further, the host 1 includes a master control device 11 (shown in fig. 2) and a conversion circuit 12 (shown in fig. 2), wherein the master control device 11 generates a square wave signal and inputs the square wave signal into the conversion circuit 12, the square wave signal is converted into a pulse signal by the conversion circuit 12, and the pulse signal is input into the magnetic coil 2, so that the magnetic coil 2 generates a time-varying magnetic field. The main control device 11 is configured to generate a square wave signal with a preset frequency, where the preset frequency is 4Hz, 6Hz, 8Hz, 9Hz, and the like, and the duty ratio of the square wave signal is 40%. That is, in this embodiment, the pulse signal is obtained by converting the square wave signal through the conversion circuit 12, that is, the signal frequency of the square wave signal is equal to the signal frequency of the pulse signal.
Further, according to the basic knowledge of brain waves, the potential change of brain waves is between 50 microvolts and 200 microvolts, the frequency change is between 1 and 30 times per second, and the potential change can be divided into four segments as shown in the following table:
| name (R) | Frequency/range (times/second) |
| Beta wave (beta) | 14～30 |
| Alpha wave (alpha) | 8～13 |
| Theta wave (theta) | 4～7 |
| Delta wave (delta) | 1～3 |
As shown in the table above, the a wave is a brain wave of 8 to 13 times per second, the amplitude of the a wave is 50 microvolts to 100 microvolts, and the a wave appears in a quiet state to wake and close eyes; when eyes are open, thinking is wrong or stimulation is received, the alpha wave disappears and a fast wave appears, namely the alpha wave is blocked. But the a wave may reappear when the eyes are quietly closed again. The beta wave is 14-30 times per second brain waves, the amplitude of the beta wave is not more than 20 microvolts, and the beta wave appears in the eyes of the tested person or the tested person listens to sudden sound or thinks, namely the beta wave is the expression of excitation of the cortex of the brain and is related to mental stress or emotional excitement. The theta wave is a brain wave 4-7 times per second, the amplitude of the theta wave is 100-150 microvolts, and the theta wave appears in the situations of sleep hypoxia or deep anesthesia. The delta wave is brain wave of 1-3 times per second, the amplitude of the brain wave is 20-200 microvolts, and the delta wave does not appear when an adult is awake, but can appear under sleep, deep anesthesia or hypoxia.
Further, sleep states are generally divided into two phases, including a non-rapid eye movement phase (NREM) and a rapid eye movement phase (REM). Specifically, the non-rapid eye movement period is slow wave sleep or synchronous sleep, which is characterized by slow wave sleep, no rapid movement of eyeballs and certain tension of muscles. The rapid eye movement period is out-of-phase or desynchronized sleep, which shows that the eyeball rapidly moves 50-60 times per minute, the frequency of electroencephalogram waves is high, the muscle tension is obviously reduced, and the eye is in a completely relaxed state.
Further, in the whole sleep process, the non-rapid eye movement period and the rapid eye movement period alternately appear, for example, from the non-rapid eye movement period, after the non-rapid eye movement period enters 90min, the non-rapid eye movement period is switched to the rapid eye movement period and sleeps for 10min to 30min, and then the non-rapid eye movement period is switched to the sleep for 90min until arousal. However, in other embodiments, the sleep time is not limited.
Further, the non-tachyplesis period includes four phases, as follows:
stage S1: in the awake state, the main wave rate is changed to a alpha wave (the alpha wave is reduced to 50 percent of the original wave rate), and the state is replaced by a mixed wave of theta wave, beta wave and alpha wave.
Stage S2: and a stage in which the a wave is further reduced in the S1 stage, the θ wave becomes the main wave rate, and a complex wave or a sleep spindle wave lasting for 0.5 seconds or more at 12 to 14 times/second appears on the background.
Stage S3: when delta wave appears on brain wave and reaches 20-50%, the three stages are determined.
Stage S4: when delta wave appears on brain wave and reaches more than 50%, four stages are defined.
Further, the time-varying magnetic field of the magnetic coil 2 may be coupled into the human body, but the human tissue cannot store the external magnetic field energy, so the effect of the magnetic stimulation is obviously not the effect of the direct action of the magnetic field, but still the result of the action of the electric current. According to the law of farad electromagnetic induction, a magnetic field changing with time can generate an electric field, and the magnitude of induced electromotive force generated by the magnetic field is in direct proportion to the change rate of magnetic flux with time. The current generated by the electric field can be introduced into the human body through the electrodes as long as the current has enough strength and a certain duration, so that the nervous system can be effectively stimulated. As is clear from the above analysis, the brain wave in the excited state is a β wave, the waking quiet state is a wave, the light sleep state is mainly a θ wave, and the deeper sleep state is a δ wave. When a person arouses to gradually enter each stage of a non-rapid eye movement period, the brain wave changes from a series of a waves to theta waves and then delta waves. The insomnia patients, especially the patients with sleep disorder, have the symptoms that the brains are still excited during sleeping, so that the patients are very clear and difficult to relax. That is, for insomnia patients, if external magnetic information with the same frequency as the theta wave frequency is directly coupled into the brain, and the brain electrical activity is gradually synchronized with the external magnetic information to enter into shallow sleep through the pacing effect of the external magnetic information, it is difficult to do so, therefore, in the embodiment, the pulse signal with the same frequency as the alpha wave frequency is generated by the magnetic coil 2 to generate the time-varying magnetic field and is coupled to the insomnia patients, so that the insomnia patients gradually enter into a quiet and relaxed state, and then the frequency of the pulse signal is reduced to the theta wave frequency, so that the magnetic coil 2 generates the time-varying magnetic field again and is coupled to the insomnia patients, so as to induce the insomnia patients to gradually enter into the S1 section and even the S2 section in the non-fast eye movement period. Thus, the frequency of the time-varying magnetic field generated by the magnetic coil 2 is gradually decreased, so that the insomnia patient gradually transits from a more excited state to a quiet and relaxed state upon waking to a light sleep.
It can be understood that the frequency of the pulse signal output by the host 1 can be set according to a preset frequency, that is, the coupling time of the time-varying magnetic field can be set according to the symptoms of the insomnia patient in the embodiment. Generally, the symptoms of insomnia patients are classified into mild, moderate and severe symptoms, for example, the coupling time of the time-varying magnetic field of the mild insomnia patients is 60 min; the coupling time of the time-varying magnetic field of the patient with mild insomnia is 100 min; the coupling time of the time-varying magnetic field of the moderate insomnia patient is 290min, wherein the magnetic coil 2 is paused for 120min after continuously operating for 100min and then automatically operates for 70min again; the coupling time of the time-varying magnetic field of the patient with severe insomnia is 430min, the magnetic coil 2 is paused for 120min after continuously operating for 100min, then is paused for 90min after automatically operating for 70min again, and then automatically operates for 50min again.
Further, the host 1 is provided with a key device 13, wherein the key device 13 includes a time selection key, a frequency selection key, etc., for example, a frequency selection signal is triggered by pressing the frequency selection key, at this time, the frequency selection signal is sent to the main control device 11 of the host 1, after receiving the frequency selection signal, the main control device 11 outputs a signal with a frequency corresponding to the frequency selection signal, where the signal output by the main control device 11 is a square wave signal and is transmitted to the conversion circuit 12, so as to be converted into a corresponding pulse signal by the conversion circuit 12 and transmitted into the magnetic coil 2, so that the magnetic coil 2 generates a corresponding time-varying magnetic field, it can be understood from the above description that the frequency of the pulse signal after the first conversion by the conversion circuit 12 is the same as the frequency of the alpha wave, so that the magnetic coil 2 generates a time-varying magnetic field and is coupled to the insomnia patient, so that the insomnia patient gradually enters a quiet and relaxed state, the frequency of the pulse signal after the second conversion by the conversion circuit 12 is the same as the frequency of the theta wave, so that the magnetic coil 2 generates the time-varying magnetic field again and is coupled to the insomnia patient to induce the insomnia patient to gradually enter a section S1 or even a section S2 of the non-rapid eye movement period, thereby facilitating the adjustment and the induction of the sleep process of the patient and realizing the functions of promoting sleep or awakening.
