Detailed Description
As shown in fig. 1, a sleep inducing device includes: the physiological signal acquisition module 100 acquires the real-time physiological signal of the acting object, the sleep depth monitoring module 200 receives the real-time physiological signal of the acting object, and sends out a control signal when the real-time physiological signal is within a preset threshold range, the optimal frequency acquisition module 300 acquires the optimal frequency related to different sleep parameters of the acting object, and the sleep induction module 400 sends out a pulse electromagnetic field according to the control signal and the optimal frequency, and the pulse electromagnetic field acts on the acting object to induce the acting object to enter a sleep state corresponding to the control signal.
The physiological signal acquisition module 100 is connected with the sleep depth monitoring module 200, and the sleep depth monitoring module 200 and the optimal frequency acquisition module 300 are respectively connected with the sleep induction module 400.
The physiological signal acquisition module 100 is configured to acquire real-time physiological signals of an acting object, where the physiological signal acquisition module 100 may specifically include an myoelectricity acquisition module configured to acquire myoelectricity physiological signals, a pulse rate acquisition module configured to acquire pulse rate physiological signals, and a sensor module configured to acquire body movement physiological signals, where the myoelectricity acquisition module, the pulse rate acquisition module, and the sensor module are respectively connected with the sleep depth monitoring module. Specifically, for myoelectric physiological signals: when the user wakes up, the amplitude of the myoelectric physiological signal is larger, and the amplitude is reduced along with the deepening of the sleeping degree; for pulse rate physiological signals, including frequency of arterial pulses, pulse rate variability (PRV, pulse Rate Variability). The pulse rate is affected by age, sex, movement, emotion and other factors. Pulse rate can be increased when exercise and emotion are excited, and pulse rate can be reduced when rest and sleep are performed. Pulse rate variability is highly correlated with heart rate variability, and can reflect autonomic nerve activity for analysis of sleep. For body movement physiological signals: in the wake-up, the physiological signals of body movement are mostly obvious and frequent, and besides the wake-up period, other phase periods can have occasional non-obvious body movement behaviors, but compared with the wake-up period, the frequency of occurrence is low, the movement amplitude is also small, and the wake-up period and the sleep period can be effectively distinguished.
The sleep depth monitoring module 200 is configured to receive and process a real-time physiological signal of an acting object, and send a control signal when the real-time physiological signal is within a preset threshold range, so as to regulate and control the sleep induction module. The control signal has a specific Pattern (Pattern) that is closely related to a specific sleep state. For example, the sleep state of the acting object is deduced through modeling after the received real-time myoelectric physiological signals, real-time pulse rate physiological signals and real-time body movement physiological signals are processed by digital filtering, wavelet decomposition and the like. The comprehensive treatment of a plurality of physiological signals can improve the monitoring accuracy of the sleeping condition of the acting object so as to better perform subsequent sleep induction. When the object is monitored to be in a certain wakefulness state and needs to assist sleep, a control signal related to the wakefulness state is sent out; when the object is monitored to be in a sleep state, a control signal is sent out to close the sleep induction module.
The optimal frequency obtaining module 300 is configured to obtain optimal frequencies related to different sleep parameters of the acting object, and specifically, the optimal frequency obtaining module is configured to search a frequency point with the minimum reflection coefficient of the antenna in a frequency band sensitive to the target area, that is, the optimal frequency. The optimal frequency refers to the optimal frequency of the carrier frequency, and is related to sleep parameters such as whether the head is off-pillow or not. Sleep parameters also include heart rate parameters, myoelectric parameters, body movement parameters, and the like. The individualized control signals, i.e. patterns, are related to sleep states of wakefulness, shallow sleep, deep sleep, etc. Control signals for different modes (patterns) associated with sleep states: the sleep states may be divided into several, such as three awake scenarios, three light sleep scenarios, and three deep sleep scenarios. In different awake situations, control signals of different modes are adopted. The same wakefulness scene is different in modes of different acting objects. The personalized pattern is deduced in the background by analyzing big data of the object, and the main parameters include the intensity of the pulsed electromagnetic field, the frequency of the pulsed modulation signal, the duty cycle, the duration, etc.
The brain is divided into different regions, which are responsible for different functions. When increased alertness is desired, the wake-up zone, which contains the blue-spotted nuclei (LC, locus Coeruleus) or the like, can be stimulated (i.e., modulated) to increase the frequency of polarization and depolarization of the cell nuclei in the zone, releasing more neurotransmitters such as acetylcholine (Ach, acetylcholine); if desired to promote sleep, the nucleus clusters near the hypothalamus, such as the extraventral side-looking anterior nucleus (VLPO, ventrolateral preoptic nucleus), may be stimulated (i.e., modulated) to become more active and release more sleep-promoting neurotransmitters, such as gamma-aminobutyric acid, etc. The operating frequencies of the different functional areas are different and the responses to the external environment are also different. For example, the frequency of the brain electrical signal is less than 4Hz when sleeping; when sleeping shallow, the frequency is 4Hz-8Hz; the frequency is 8Hz-13Hz in the relaxation state; the arousal is typically greater than 13Hz and as the frequency increases, the state of consciousness is the more awake.
The sleep inducing module 400 receives the control signal and the optimal frequency, generates a pulsed electromagnetic field according to the control signal and the optimal frequency, and then targets the pulsed electromagnetic field to a target area of the acting object to adjust the working frequency of the target area. For example, a pulsed electromagnetic field is targeted to the hypothalamus of a subject to be treated to be more active and to release more neurotransmitters that promote sleep, to induce the subject to rapidly enter a sleep state corresponding to the control signal. Specifically, if the object to be detected is in the first awake scene, the target frequency of the target area is greater than or equal to 15Hz, the optimal frequency given by the sleep parameter is 5GHz, and the pulse electromagnetic field output by the sleep induction module may be an electromagnetic field with a control signal of 1kHz, a duty ratio of 10%, a peak power of 40dBm, and a carrier frequency of 5 GHz. The polarization and depolarization frequency of the cell nucleus in the target area is more than or equal to 15Hz through targeted energy and information transmission, and more neurotransmitters for promoting sleep are released to enter a sleep state rapidly. The target frequency of the target region is acquired by experimental and professional instruments, such as an EEG (electroencephalograph) device, a PET (Positron Emission Computed Tomography, positron emission tomography) instrument, an fMRI (functional magnetic resonance imaging ) instrument, and the like. A set of control signals generates a specific pattern to address different situations and different objects.
The sleep induction device comprises a physiological signal acquisition module 100, a sleep depth monitoring module 200, an optimal frequency acquisition module 300 and a sleep induction module 400, wherein the physiological signal acquisition module 100 is connected with the sleep depth monitoring module 200, and the sleep depth monitoring module 200 and the optimal frequency acquisition module 300 are respectively connected with the sleep induction module 400. The physiological signal acquisition module 100 is used for acquiring real-time physiological signals of an acting object, the sleep depth monitoring module 200 is used for receiving and processing the real-time physiological signals of the acting object, and sending out control signals when the real-time physiological signals are in a preset threshold range, the optimal frequency acquisition module 300 is used for acquiring optimal frequencies related to different sleep parameters of the acting object, and the sleep induction module 400 receives the control signals and the optimal frequencies and sends out pulse electromagnetic fields according to the control signals and the optimal frequencies. The pulse electromagnetic field acts on the acting object, and the action of the target area is guided through the targeting action on the target area of the acting object so as to induce the acting object to quickly enter a sleep state corresponding to the control signal. The sleep inducing device can effectively improve sleep quality and solve the problem of sleep disorder.
In one embodiment, the frequency of the pulse electromagnetic field in the sleep inducing device is the frequency in the frequency band sensitive to the target area, and the frequency of the pulse electromagnetic field is the optimal frequency acquired by the optimal frequency acquisition module. The specific frequency value of the pulse electromagnetic field can be selected by the optimal frequency acquisition module according to sleeping parameters such as head off pillow and the like. For example, in a certain awake state, the target frequency of the target area is more than or equal to 15Hz, and the optimal frequency acquisition module acquires that the optimal frequency related to different sleep parameters of the acting object is 5GHz, then the pulse electromagnetic field is an electromagnetic field with a control signal of 1kHz, a duty ratio of 10%, a peak power of 40dBm and a carrier frequency of 5 GHz. When the half wavelength of the pulse electromagnetic field is close to the size of the target area, the energy and information of the pulse electromagnetic field can be transmitted to the target area to the greatest extent, and the resonance effect is realized. Close correlation, specifically half wavelength or integer multiples of half wavelength, approximately corresponds to the size of the target area. The modulation frequency of the pulse electromagnetic field is changed according to the requirement to guide the actual working frequency of the target area of the acting object, namely, the polarization and depolarization frequency of nerve cells are changed, so that the function of the target area is enhanced. It is considered that a single pulse has very little effect on the polarization and depolarization frequency of the target region. Therefore, n pulses are required to increase the frequency of polarization and depolarization of the target region by 1 Hz. Typically, n is between 40 and 200. If the frequency needs to be increased by 5Hz, the relevant modulation frequency is between 200Hz and 1000Hz, and parameters such as sleeping situation, acting objects and the like are specifically selected to be different.
In one embodiment, the sleep depth monitoring module in the sleep inducing device includes a controller that receives and processes the real-time physiological signal of the subject and issues a control signal when the real-time physiological signal is within a preset threshold range. For example, the controller receives the real-time myoelectric physiological signal, the real-time pulse rate physiological signal and the real-time body movement physiological signal, and compares the real-time myoelectric physiological signal, the real-time pulse rate physiological signal and the real-time body movement physiological signal with corresponding preset threshold ranges respectively to obtain that the acting object is in the wake-up period or the sleep period. The sleep condition of the acting object is obtained by comparing the real-time values of the three physiological signals with the preset threshold value, so that the monitoring accuracy of the sleep condition of the acting object can be improved, and the subsequent sleep induction can be better carried out. The controller sends out a control signal representing sleep when detecting that an acting object is in an awake period and needs to assist sleep; when the object is monitored to be in sleep stage and needs to be awake, a control signal for representing the wakefulness is sent out. More specifically, the controller may employ an STM32 series control chip, such as an STM32F413CGU6 control chip. STM32F413CGU6 control chip is based on 32 bit Cortex-M4 architecture kernel, built-in flash memory, RAM (Random Access Memory ), analog-to-digital converter, timer/counter and USART (Universal Synchronous/Asynchronous Receiver/Transmitter, universal synchronous/asynchronous serial receiver/Transmitter) communication port, etc., and clock frequency can reach 100MHz at most. The high-performance controller is reasonably selected, so that the system integration is facilitated, and the miniaturization of products is facilitated; meanwhile, the accuracy and the instantaneity of monitoring can be improved.
In one embodiment, the sleep depth monitoring module in the sleep inducing device further comprises an interaction module. The interaction module is connected with the controller and is used for facilitating user operation. Specifically, the interaction module may include a wear detection module, a display module, and an on-off module. When the wearing detection module detects that the wearing of the user is good, the wearing detection module sends an acquisition start signal to the controller, and the controller sends an instruction to the physiological signal acquisition module to automatically start a data acquisition function; when the user wearing is detected to be incorrect, for example, the real-time signal detected by the infrared sensor or the capacitance sensor is not in the preset threshold range, an acquisition closing signal is sent to the controller, the controller cannot start the data acquisition function, and an incorrect wearing prompt is output to the display module. The display module can display the current time, the connection state, the battery power, the working state of the sleep inducing device, the off-pillow state of the person to be tested, the wearing state and the like. The display module may include an OLED (Organic Light-Emitting Diode) display screen, which is also called an Organic laser display or an Organic Light-Emitting semiconductor, and has advantages of self-luminescence, wide viewing angle, almost infinite contrast, low power consumption, and extremely high reaction speed. The on-off module may include a key switch, for example, the OLED display may be activated or switched by a short press of the key switch, and the sleep inducing device may be turned on or off by a long press of the key switch. Specifically, the short press may be less than 2 seconds long and the long press may be greater than or equal to 3 seconds long. The display module is connected with the controller to intuitively display the output information of the controller, the display module comprises a display driving circuit and a display, the controller is connected with the driving circuit, and the driving circuit is connected with the display. For example, the controller receives the acquisition closing signal sent by the wearing detection module, outputs a wearing incorrect prompt message instruction, and drives the display to display an 'incorrectly worn' interface after receiving the instruction.
In one embodiment, the sleep inducing module in the sleep inducing device comprises a control chip that issues pulsed electromagnetic field generation instructions according to the control signal and the optimal frequency. For example, the control signal received by the control chip is a control signal for representing sleep, and the target frequency of the target area of the received acting object is 12Hz. The control chip sends out a pulse electromagnetic field generating instruction which can enable the target area to enter a target state according to the received control signal representing sleep and the target frequency of the target area of the acting object. The pulse electromagnetic field generated according to the pulse electromagnetic field generation instruction acts on the target area of the acting object, and the target area is guided to enter a target state through the targeting action on the target area so as to induce the acting object to enter a sleep state. The control chip can comprise an STM32L442KCU6 control chip, and the control chip is based on 32-bit ARM Cortex M4, the maximum clock frequency is 80MHz, the program memory size is 256KB, the data random memory size is 256KB, the 12-bit analog-digital converter is ultra-low in power consumption (8 nA when in a closing mode and 84uA/MHz when in an operating mode), and QFN-32 packaging (5 mm by 0.6mm in size) has rich peripheral interfaces. By reasonably selecting the microcontroller, the real-time monitoring performance is improved, and the power consumption and the size of the system are reduced.
In one embodiment, the sleep inducing module in the sleep inducing device further comprises a radio frequency module for emitting a pulsed electromagnetic field according to the pulsed electromagnetic field generation instruction, and the radio frequency module is connected with the control chip.
