Description

Sleep physiological system

This creation relates to a sleep physiological system and a sleep warning method, in particular, to a sleep physiological system and a sleep warning method that can assess and improve sleep disordered breathing.

Sleep Apnea (Sleep Apnea) is a type of sleep breathing disorder, which generally has three types: Obstructive Sleep Apnea (OSA), Central Sleep Apnea (Central Sleep Apnea, CSA), and Mixed Sleep Apnea Pause (Mixed Sleep Apnea, MSA).

The main feature of obstructive sleep apnea (OSA) is that during sleep, due to complete or partial obstruction of the upper airway, the respiratory airflow decreases or stops for a period of time, and it is usually accompanied by a decrease in blood oxygen concentration (desaturation) OSA is a common sleep-disordered breathing, affecting about 25-40% of the middle-aged population.

Central sleep apnea (CSA) is caused by problems in the mechanism of the brain driving muscles to breathe, which makes the nerve drive of the breathing muscles stop for a short time, and these transients may range from 10 seconds to 2 to 3 minutes. Lasting throughout the night, central sleep apnea, similar to obstructive sleep apnea, will cause gradual asphyxia during sleep. As a result, the individual will be briefly aroused from sleep and resume normal breathing at the same time. And similar to obstructive sleep apnea, central sleep apnea can cause arrhythmia, high blood pressure, heart disease, and heart failure.

Mixed sleep apnea (MSA) refers to a situation where both obstructive sleep apnea and central sleep apnea are mixed.

Apnea Hypoxia Index (AHI) is an indicator of the severity of sleep apnea, which combines sleep apnea (Apnea) and sleep breathing The number of hypopneas (hypopnea) to give an overall sleep apnea severity score that can simultaneously evaluate the number of sleep (breathing) interruptions and the degree of oxygen saturation (blood oxygen level). Among them, AHI is a combination of sleep apnea and The total number of hypopnea events is divided by the number of hours of sleep. Usually, the AHI value is divided into 5-15 times per hour as mild, 15-30 times per hour as moderate, and >30 per hour as severe.

In addition to AHI, studies have confirmed that another important indicator for assessing or detecting sleep apnea is the oxygen desaturation index (Oxygen Desaturation Index, ODI), which refers to a certain degree of drop in blood oxygen level per hour from baseline during sleep. Generally speaking, ODI is expressed in two ways: the number of times oxygen saturation drops by 3% (ODI3%) and the number of times oxygen saturation drops by 4% (ODI4%). The difference between ODI and AHI is that AHI also includes possibilities An event that causes sleep arousal (awaken) or arousal (arousal), but does not affect oxygen levels. Research has confirmed that ODI has a certain correlation with AHI and sleep apnea, and can be effectively used to diagnose OSA.

In addition, low oxygen level is also another indicator that can be used to evaluate the impact of sleep apnea, which refers to the ratio between the total time when the blood oxygen saturation is below 90% and the total monitoring time. Since both AHI and ODI are calculated based on the number of occurrences, they may not accurately reflect the effects of continuous low blood oxygen levels without frequent fluctuations in blood oxygen. Low oxygen levels can make up for this deficiency. There is also a certain correlation between low oxygen levels and sleep apnea.

Most OSA patients will have more OSA events when lying on their back. This is because the upper airway is more susceptible to gravity and collapse when lying on their back. In the literature, it is officially diagnosed as postural OSA ( Positional OSA, POSA) is based on the fact that the difference between the AHI value when lying on the back and when not lying on the back is greater than a certain threshold. For example, one of the common definitions of POSA is that the AHI value when lying on the back is greater than that when lying on the back. The AHI value is more than twice; According to research, the penetration rate of POSA decreases with the increase of OSA severity, and 70%~80% of POSA patients have mild to moderate OSA severity. Among them, Asian Up to 87% of patients with mild OSA can be classified as POSA patients.

Another common sleep-disordered breathing is snoring, which affects 20%-40% of the total population. This type of noise-producing symptom is caused by the softness of the upper respiratory tract airflow during sleep. Occurred by tissue vibration, OSA and severe snoring have been proved to be highly correlated with many clinical symptoms, such as daytime sleepiness, depression, formation of high blood pressure, ischemic heart disease, cerebrovascular disease, etc. Among them, snoring It is the most common symptom that accompanies OSA, and snoring is also generally considered to be a precursor to OSA. Based on the fact that both causes are related to the physiological phenomenon of upper respiratory tract stenosis, sleeping posture also affects the severity of snoring symptoms. .

According to research, with the progression of upper respiratory tract stenosis, it is usually the case that snoring symptoms related to sleeping postures occur first, and when it is more serious, snoring is prone to occur even when not lying on your back, and begins to develop into a mild one. OSA, and the correlation between the occurrence of snoring and sleep posture has gradually decreased. Furthermore, the severity of OSA has also changed from mild to moderate related to sleep posture, and finally becomes a severe situation that is less related to sleep posture.

Sleep positional training (SPT) is a method that can treat postural OSA and postural snoring. In recent years, a new generation of posture training devices has been developed. Through the central axis of the body, such as the neck, chest or abdomen, Set up a posture sensor, such as an accelerometer, and when it detects that the user’s sleeping posture is lying on his back, it generates a weak vibration warning to prompt the user to change his sleeping posture to avoid lying on his back. According to many research reports It is pointed out that through this simple but effective treatment method, patients can be prevented from lying on their backs during sleep, thereby greatly reducing the number of OSA events.

However, there is still room for improvement in such training methods. For example, because patients with OSA or snoring have different degrees of severity and individual physiological differences, before training, if an evaluation function can be provided, it can provide targeted Training programs and expected information about training effects; in addition, if sleep and breathing information can be provided during sleep posture training, the device's parameter settings can also be adjusted to achieve the purpose of improving training effects.

In addition, in addition to postural training, if other training methods can be provided, for example, for non-postural sleep-disordered breathing, or further strengthening based on postural training, it will be more helpful.

Figure 1 illustrates a schematic circuit diagram of the sleep physiology system 100 according to the present case, in which all the components in the same device are connected to a control unit in the device, wherein the control unit includes at least one microcontroller/microprocessor and is configured to Loaded with programs to control the communication between hardware components. The control unit can achieve signal transmission between different hardware components and external applications/external devices connected to the device and/or system. Behaviors can be programmed to respond to different operating conditions, and the microcontroller/microprocessor will also use an internal timer (not shown) to generate a time stamp or time difference, or to control operations.

In addition, the control unit also includes at least an analog front end (AFE) circuit for obtaining physiological signals to perform, for example, analog-to-digital conversion, amplification, filtering, and various other signal processing known to those with ordinary knowledge in the art The procedures, since these are all known content, so I won't repeat them.

The system may include a light sensor. In this case, a light sensor refers to a light-emitting source, such as an LED, and a light detector, such as a photodiode. The sensor, as well known, uses the principle of PPG (photoplethysmography) to emit light into human tissues through a light-emitting source, and the photodetector receives the blood that penetrates the blood vessel or is reflected by the blood. Light, and then obtain blood physiological signals by obtaining the volume changes of the blood due to the light. Therefore, the blood physiological signals obtained by the light sensor are generally called PPG signals, and the PPG signals include fast-moving components ( AC Component, which reflects the pulse wave generated by myocardial contraction transmitted through the artery, and the slow-moving component (DC Component, DC component), which reflects the slower changes in tissue blood volume, for example, breathing action (Respiratory Effort) (That is, the expansion and contraction of the chest and abdomen during breathing), the influence caused by sympathetic and parasympathetic nerve activity; in addition, physiological information such as blood vessel hardness and blood pressure can also be obtained by analyzing the PPG signal; in addition, it is learned through physiological experiments The PPG pulse wave can be analyzed in the frequency domain to obtain the harmonic resonance between the organs and the heart rate. Therefore, this pulse wave heart rate harmonic resonance distribution can be applied to the diagnosis of Chinese medicine and the monitoring of human blood circulation, such as liver and The liver meridian is related to the first harmonic of the heartbeat frequency, the kidney and kidney meridians are related to the second harmonic of the heartbeat frequency, the spleen and spleen meridians are related to the third harmonic of the heartbeat frequency, and the lungs and lungs are related to the fourth harmonic of the heartbeat frequency. Correlation, and the fifth harmonic of the heartbeat frequency of the stomach and stomach meridians.

Generally speaking, the blood physiological information that can be obtained varies according to the type and quantity of light-emitting sources and light detectors included in the light sensor. For example, the light sensor may include at least one light-emitting source For example, an LED or a plurality of LEDs, preferably, green light/infrared light/red light, and at least one light detector to obtain blood physiological information such as pulse rate/heart rate and breathing movement; wherein, the pulse rate is measured /At heart rate, green light and visible light with a wavelength below green, such as blue light and white light, are currently the main light sources used for heart rate measurement, and the main emphasis is on the interpretation of the AC component. In addition, the impact of breathing on the blood Yes, when a person breathes, the pressure in the chest cavity (the so-called intrathoracic pressure) changes with each breath. When inhaling, the chest cavity expands and the intrathoracic pressure decreases, thus drawing air into the lungs. During exhalation, the intrathoracic pressure increases and forces air out of the lungs. These changes in intrathoracic pressure will also cause changes in the amount of blood returning to the heart through the veins and the amount of blood entering the arteries from the heart. The change can be known by analyzing the DC component of the PPG signal. In this article, the breathing information obtained by analyzing the PPG waveform is called low-frequency breathing behavior; in addition, since the heart rate is affected by the autonomic spirit It is controlled, so breathing will affect the autonomic nervous system and cause changes in the heartbeat, that is, the so-called sinus arrhythmia (Respiratory Sinus Arrhythmia, RSA), generally speaking, the heartbeat will accelerate during inhalation, and During exhalation, the heartbeat slows down, so the breathing changes can also be learned by observing the heart rate. In this article, this is called RSA breathing behavior; therefore, the breathing information obtained through the light sensor is collectively called breathing behavior.

Alternatively, the light sensor may also include at least two light-emitting sources, for example, a plurality of LEDs, preferably, green light/infrared light/red light, and at least one light detector to obtain the blood oxygen concentration (SPO2) Physiological information of blood, pulse rate/heart rate, and breathing movement, among which, when measuring blood oxygen concentration, two different wavelengths of light are required to enter the tissues, using oxygenated heme (HbO2) and non-oxygenated heme in the blood (Hb) has different absorption levels for two wavelengths of light, and after receiving the transmitted and reflected light, the result of the comparison between the two can determine the blood oxygen concentration. Therefore, the measurement of blood oxygen concentration is usually for light sensing There are more restrictions on the setting position of the device. The position where light can actually penetrate into the artery is better, for example, fingers, palm inner surface, toe, sole, etc., especially when measuring infant’s blood oxygen concentration, toes/soles are often used. The two different wavelengths can be, for example, red light and infrared light, or two wavelengths of green light, such as green light with wavelengths of 560nm and 577nm respectively. Therefore, suitable light sources can be selected according to requirements without limitation. .

The wavelength range of the above-mentioned various light sources is that the wavelength of red light is approximately between 620nm and 750nm, the wavelength of infrared light is approximately greater than 750nm, and the wavelength of green light is approximately between 495nm and 580nm. When used for measurement, it is usually used, For example, the wavelength of red light is 660nm, the wavelength of infrared light is 895nm, 880nm, 905nm or 940nm, and the wavelength of green light is 510~560nm or 577nm. However, it should be noted that in actual use, depending on the purpose of use, it can also be used. The use of light sources of other wavelengths, for example, when you only want to obtain the heart rate, other visible light sources with a wavelength less than green light, that is, visible light with a wavelength less than 580nm, such as blue light, is also one of the options, and, in addition to using specific wavelengths In addition to a single light source, a composite light source containing this wavelength, for example, white light, can also be used.

For example, in particular, light sources of three wavelengths may be simultaneously available. For example, in one embodiment, the first light source is implemented as an infrared light source to generate light of the first wavelength, and the second light source is implemented as a red light source to generate light of the second wavelength. Wavelength of light, and the third light source is implemented as a green light source to produce the first Three-wavelength light, where the infrared light source and the red light source are used to obtain the blood oxygen concentration, and the green light source is used to obtain the heart rate; or, in another embodiment, the light of the first wavelength and the second wavelength are implemented as green light, And the light of the third wavelength is implemented as infrared light or red light. Two of the wavelengths can be used to obtain the blood oxygen concentration and the other wavelength to obtain the heart rate; or, in another embodiment, the first wavelength, the second wavelength, And the third wavelength of light is implemented as green light. Two of the wavelengths of green light can be used to obtain blood oxygen concentration, and the other wavelength of green light can be used to obtain heart rate. As shown above, blood can be obtained from different parts of the body. There are different types of physiological information. Therefore, having a light source that can generate multiple wavelengths at the same time will help achieve the purpose of obtaining various required blood physiological information by moving to different body parts through the same device, for example, when the blood oxygen concentration is needed , Move the device to a position where light can penetrate the artery, and when you need to obtain heart rate or other blood physiological information, you can just have a blood vessel. Therefore, there is no limit.

Furthermore, when obtaining the heart rate, in order to eliminate noise, such as environmental noise, noise generated by body movements during wearing, etc., multiple light sources can also be set (and the wavelength is not limited, all of which can be green or Use other wavelengths of light source), and through the PPG signals obtained from different light sources, through digital signal processing, such as adaptive filter (Adaptive Filter) or mutual subtraction calculations to achieve the purpose of eliminating noise, so there is no limit .

The system may include a posture sensor, usually an accelerometer, preferably a three-axis (MEMS) accelerometer, which can define the posture of the device in a three-dimensional space and is directly related to the user’s sleeping posture , Among them, the accelerometer will return the acceleration values measured in all three dimensions of x, y, and z. Based on these values, in addition to the sleeping posture, many other sleep information can be derived, for example, Physical activity (actigraph), movement, standing/lying posture changes, etc., in which, by analyzing physical activity during sleep, you can further obtain information about sleep stages/states; in addition, other types of accelerometers can also be used, For example, gyroscope, magnetometer, etc.

The system may include a microphone, which reports the frequency and amplitude of the measured sound, and uses an acoustic transducer with appropriate filtering design to detect sleep sounds, such as snoring or breathing.

The system can include a snoring detector, which can be implemented through the aforementioned microphone Sound detection can also be implemented to detect body cavity vibration caused by snoring. Accelerometers or piezoelectric vibration sensors can be used. The measured positions include, for example, torso, neck, head, ears, etc. Among them, the torso and head are better positions, especially the nasal cavity, throat, chest cavity, etc., which can transmit the vibration caused by snoring well, which is a very advantageous choice. In addition, compared to detecting sound, Vibration detection can not be disturbed by environmental noise, and it can also be detected under the condition of covering the body, such as a quilt, which has a wider application range; therefore, the accelerometer as a posture sensor can also be detected at the same time. It is used to obtain information about snoring and make it more convenient to use. Furthermore, snoring-related information, such as intensity, duration, number of times, etc., is obtained from the original vibration signal by using appropriate filter design and known techniques, and is due to the signals obtained by different sensors The types and acquisition methods are different, so different appropriate filter designs should be adopted accordingly.

The system may include a temperature sensor to detect device temperature, ambient temperature, or body temperature to provide further physiological information of the user during sleep.

The system may include a respiratory air flu detector, such as a thermistor, thermocouple, or respiratory airflow tube, which is arranged between the mouth and nose to obtain changes in respiratory airflow. Among them, the thermistor and thermocouple can be selected in It is feasible to set two detection points near the nostrils, or choose to set three detection points near the nostrils and near the mouth.

The system can include an accelerometer, which can be set on the torso to obtain the acceleration and deceleration caused by the chest and/or abdomen undulations during the breathing movement; it can also be used to detect the blood vessel pulse generated by the blood pulse to obtain the heart rate and obtain The position is not limited, for example, the head, chest, upper limbs, etc. are all available positions.

The system may include at least two impedance detection electrodes, which are arranged on the trunk to obtain impedance changes caused by breathing.

The system may include a piezoelectric motion sensor, which is arranged on the torso, which obtains a signal by applying force on the piezoelectric motion sensor through a breathing motion. It is usually implemented in the form of a belt around the torso, or may be implemented It is a form that partially covers the torso.

The system may include a RIP (Respiratory Inductance Plethysmography) sensor, which is set on the torso to obtain the expansion and contraction of the chest and/or abdomen caused by breathing. It is usually implemented as a belt around the torso Body form.

The system may include at least two EEG electrodes, at least two ocular electrodes, and/or at least two EEG electrodes, for example, two EEG electrodes arranged on the head and/or ears, and/or arranged on the forehead, Two EOG electrodes near the eyes and/or two EMG electrodes set on the body to obtain EEG signals, EO signals, and/or EMG signals, and by analyzing EEG signals, EO signals, And/or myoelectric signal, you can know the sleep state/stage, sleep cycle, etc. during sleep, which helps to understand the quality of sleep.

Here, it should be noted that generally when capturing electrophysiological signals, signal extraction electrodes and ground electrodes are often installed. Among them, the signal extraction electrodes are used to obtain electrophysiological signals, and the function of the ground electrodes is to remove the background. Noise, and all the electrodes described in this article are signal extraction electrodes. However, in order to avoid too long words, in the following description, "electrodes" are used to represent "signal extraction electrodes", as for grounding The setting of the electrode is generally set selectively according to actual needs, so it will not be repeated in this article.

Information about sleep stages/states can also be obtained by analyzing heart rate. For example, there is a certain relationship between heart rate changes during sleep and sleep stages, for example, heart rate changes during deep sleep and light sleep It is different, so it can be learned directly by observing the heart rate distribution during sleep. In addition, other common analysis methods can also be used. For example, HRV analysis can learn the activity of the autonomic nerve, and the activity of the autonomic nerve is also related to the sleep stage. Hilbert-Huang transform (HHT) and other applicable methods can also be used to analyze changes in heart rate. Moreover, heart rate and body movements are often observed at the same time to determine information about sleep stages.

The system may include a warning unit. Many types of warnings are available, including: auditory, visual, tactile, for example, sound, flashing, electrical stimulation, vibration, etc., or any other warning that can be applied to notify the user. Among them, when vibration warning is used, it is preferably Use a vibration motor to provide a more comfortable warning that does not disturb the user’s sleep. Alternatively, in some environments, the warning unit can use speakers or earphones for audible warnings (air conduction or bone conduction), or Use LEDs for visual warnings.

The system may include an information providing interface, preferably an LCD or LED display element, to provide information to the user, such as physiological information, statistical information, analysis results, Stored events, operation modes, warning content, progress, battery status, etc. are not restricted.

The system may include a data storage unit, preferably, a memory, such as an internal flash memory, or a removable memory disk, to store the measured physiological information.

The system can include at least one communication module, which can be implemented as a wireless communication module, such as Bluetooth, BLE, Zigbee, WiFi, RF or other communication protocols, or as a wired communication module, such as USB interface, UART The interface is used to communicate in the system and/or to communicate with external devices, where the external devices may include, but are not limited to, smart devices such as smart phones, smart bracelets, smart glasses, smart headsets, etc., Tablet computers, notebook computers, personal computers, that is, can include devices installed on or around the user, and communication allows information to be exchanged between these devices, and also enables information feedback, remote control, and monitoring, etc. Operation can be carried out. Here, a smart device refers to a person with an open platform and can use a loaded program and/or a pre-loaded program to control its behavior. There are various possibilities.

The system may include a power module, such as a button cell, an alkaline battery, or a rechargeable lithium battery. The system may also have a charging module, such as an inductive charging circuit, or by Optionally, USB port or pogo pin for charging.

Next, please refer to FIG. 2, which shows the positions where the various physiological sensors and warning units can be set during sleep. The available sleep physiological information and detailed setting details are as follows.

Sleep position is acquired by a posture sensor, and the acquired position is around the central axis of the body, including: the top area 200, forehead area 201, ear area 202, snout area 203, chin area 204, neck area 205, The chest area 206 and the abdomen area 207 can be set on any body surface surrounding the central axis of the body, for example, the front, back, etc., as long as the sleeping position can be obtained by conversion. Among them, the trunk and the torso The upper neck is the most representative.

The blood oxygen concentration change is acquired by a light sensor, and the acquired positions include: forehead area 201, ear area 202, snout area 203, arm area 208, finger area 209, and foot area 211.

The heart rate can be obtained with a light sensor, and the position is not limited. Among them, the The finger area 209, arm area 208, ear area 202, head area 210, etc. are used, but any position of the body can be used. In addition, a highly sensitive accelerometer can also be used to detect the vascular vibration caused by blood pulsation to obtain The heart rate and the position to be obtained are also not limited, for example, the head, chest, upper limbs, etc. are all obtainable positions.

Respiratory Effort refers to chest and/or abdominal activity caused by breathing. It can be obtained by using accelerometers, piezoelectric motion sensors, RIP sensors, or impedance detection electrodes. The obtained positions include: chest area 206 And the abdominal area 207.

Breathing behavior is a general term for breathing information obtained by light sensors. As mentioned above, there are two types. Low-frequency breathing behavior is based on the breathing information obtained by analyzing the PPG waveform, and RSA breathing behavior is calculated based on the heart rate. There is no limit to the location where the breathing information can be obtained. Among them, the finger area 209, the arm area 208, the ear area 202, the head area 210, etc. are more commonly used, but any position on the body can be used.

The respiratory airflow changes are acquired by a respiratory airflow detector (for example, a thermistor, thermoelectric lotus, airflow tube, etc.), and the acquired position is the mouth and nose area 203.

Snoring related information (snoring sound) and breathing sounds can be obtained by using a microphone. The location is not limited, and it can also be obtained outside the body, such as using a mobile phone.

Snoring related information (body cavity vibration) is obtained by using an accelerometer or a piezoelectric vibration sensor. The obtained positions include: head area 210, neck area 205, chest area 206, and abdominal area 207.

The EEG signal is obtained by using EEG electrodes, and the obtained position is the head region 210.

The ocular signal is obtained using ocular electrodes, and the obtained position is the forehead area 201.

The electromyographic signal is obtained by using electromyographic electrodes, and the obtained position is not limited, for example, the forehead area 201 and the chin area 204.

Physical activity can be obtained with an accelerometer, and the position can be obtained without limitation.

During the sleep phase, it can be obtained by light sensors and/or acceleration, and the position is not limited, and it can also be obtained by EEG electrodes, EOG electrodes, and/or EMG electrodes. The position is mainly the head; further, By analyzing the distribution of sleep stages, such as the proportion of deep sleep and light sleep in the overall sleep, we can understand the quality of sleep.

Furthermore, the warning unit that provides vibration warning can be installed in any position where the body can feel the vibration, and the warning unit that provides sound warning is preferably installed near the ear, for example, when air-conducted sound warning is used, it is installed in the ear The canal and ear canal opening is better, and when the bone conduction sound warning is used, the range that can be set is wider, except for the ears, the entire skull can be set in the range, preferably hairless, and the warning is provided Not limited to a single form, two or more forms of warning can also be provided at the same time, for example, vibration and sound are provided at the same time. In addition, there are different options for vibration warning methods. For example, different combinations of vibration can be combined according to various changes in intensity, frequency, duration, etc. In addition to allowing users to choose a suitable vibration method, it also helps to avoid occurrences. Feeling tired.

It should be noted that the ear area 202 includes the inner surface and back of the auricle, the ear canal, and the head near the ear, the arm area 208 includes the upper arm, forearm, and wrist, and the neck area 205 includes the neck Front and back.

In addition, when setting up, for example, when the housing containing the physiological sensor is placed on the body surface, various suitable wearing structures can be used to achieve this. For example, a ring body or a belt body can be used, for example, a surrounding head Parts, arms, fingers, neck, torso, etc.; use adhesion structures, for example, to stick to any position on the body surface such as forehead, torso, etc.; use (mechanical or magnetic) clips, for example, to clamp a part of the body Parts, such as fingers, ears, etc., or clipped to objects set on the body surface, such as clothes, belts around the body, etc.; and/or use pendants, such as hanging on the auricle, etc., therefore, no Limited to a specific form of wearing structure.

It can be seen from the above that even the same kind of physiological information can be obtained without limitation by using different types of physiological sensors and by selecting different body regions. In addition, you can also choose to use more than two kinds of physiological information at the same time. Detector and/or obtain two or more physiological information and/or be installed in two or more body regions. Therefore, in actual implementation, there are various combination changes and possibilities. Therefore, the following embodiments are only examples Explanation, not limitation, as long as it falls within the above range, it belongs to the scope of this case.

The PPG signal obtained by the light sensor is related to the occurrence of sleep apnea/hypopnea, in addition to obtaining blood oxygen concentration to calculate ODI value, low oxygen level and other data well known to those with ordinary knowledge in the art. It will also produce other changes, and it is sufficient to judge whether sleep The basis of sleep apnea/hypopnea.

The occurrence of obstructive sleep apnea will cause relative bradycardia and an increase in the pulse wave amplitude (PWA) of the PPG signal, as well as a rapid increase in heart rate and strong blood vessels that occur immediately after the end of the respiratory obstruction. Contraction, this phenomenon is called the heart rate change sleep breathing event in this article, and according to research, there have been reports that, for patients with sleep breathing disorder, compared to the heart rate (HR) / pulse wave peak interval (Peak- The to-peak interval (PPI) changes, and sleep-respiratory events and awakening have more changes in PWA and/or pulse area (PA).

Among them, as shown in Figure 6, PPI is defined as the time difference between two consecutive peaks in the PPG signal. First, detect the peak value (Peak.amp) of each cycle of the PPG signal, and store the time stamps of all Peak.amp points in the array buffer. PPI is calculated as the time difference between consecutive Peak.amp points, in order to obtain For accurate results, a reasonable range of PPI value can be set. For example, PPI<0.5 second (>120 times/minute) or PPI>1.5 seconds (<40 times/minute) is considered abnormal and removed.

PWA is defined as the difference between peak amplitude (Peak.amp) and valley amplitude (Valley.amp). Peak.amp and Valley.amp are the maximum and minimum amplitude points of each PPG cycle. First, all Peak.Amp and Valley.amp points are detected as the local maximum and minimum points of the PPG signal. If there is a lack of Peak.amp points, the following Valley.amp points are also discarded. Finally, through the slave Calculate PWA by subtracting Valley.amp from the immediately preceding Peak.amp. Since Peak.amp and Valley.amp points are only tested in pairs, otherwise they will be discarded. Therefore, there will be no error in the PWA value due to missing one of the values. In addition, if there are any abnormal Peak.amp points, the PPI feature extraction is used The filtering procedure mentioned in to exclude them.

PA represents a triangular area formed by a Peak.amp point and two Valley.amp points (see Figure 6). Similar to the extraction of PWA features, all Peak.amp and Valley.amp points are detected as the local maximum point and local minimum point in the PPG signal, and because the time stamp (ie the number of samples per point) is also recorded, Therefore, the pulse wave area can be calculated from each pulse wave shape.

Respiratory signal RIIV (Respiratory Induced Intensity Variation, breathing The intensity change caused by breathing is caused by the change of blood volume in synchronization with breathing. It can be filtered and extracted from the PPG signal through a band-pass filter, for example, 0.13-0.48Hz, 16-level Bessel filter (16th degree Bessel filter) , And this filter will suppress the heart-related changes in the PPG signal and frequencies below the respiratory rate, such as sympathetic nerve activity and reflex changes in response to the vagus nerve activity.

Therefore, in order to detect sleep apnea/hypopnea events and their onsets, it is also possible to use PPI, PWA, PA derived from PPG waveforms, and RIIV from a light sensor. As an indicator.

Based on the above, the terms in this case are defined as follows:

Sleep physiological information, including at least: sleep posture related information, sleep stage, sleep physical activity, blood oxygen concentration, heart rate, breathing action, changes in respiratory airflow, breathing behavior, changes in breathing sound, snoring related information, EEG signals, ocular signals , And the EMG signal.

Sleep breathing physiological information, including at least: blood oxygen concentration, heart rate, breathing action, changes in respiratory airflow, breathing behavior, changes in breathing sound, and snoring related information.

Sleep breathing events include: blood physiological sleep breathing events (oxygen desaturation events, low oxygen level events, heart rate changes sleep breathing events), snoring events, sleep apnea events, and sleep breathing hypopnea events.

Next, this case provides a sleep breathing physiological feedback training based on sleep breathing events, and Figure 3 shows a schematic flow chart of using sleep breathing physiological feedback training to improve sleep apnea.

The main way to proceed is to use software programs to monitor sleep-respiratory physiological information. When the patient’s sleep-respiratory physiological information meets a preset condition during sleep, the alert unit is triggered to generate a warning, such as hearing, touch, vision, etc. To allow the user to have a partial arousal (awaken) or arousal (arousal) sufficient to interrupt the sleep breathing event, thereby achieving the effect of preventing sleep apnea/hypopnea. Among them, if arousal is not detected, for example, according to If the physiological information of sleep breathing is obtained, the intensity of the warning will increase in the next sleep apnea/hypopnea.

This monitors sleep breathing events and their onset, and periodically and continuously short wake up The method of patient sleep is a feedback training used to prevent sleep apnea/hypopnea, so that when the user experiences repeated sleep apnea/hypopnea when using the system, he will instinctively learn to proceed when the event occurs. Return to sleep after a few deep breaths. According to research and experiments, after a period of use, this conditional response to warnings can effectively reduce or eliminate sleep apnea/hypopnea.

Here, the preset condition can be changed with the obtained physiological information of sleep breathing, for example, the preset blood oxygen concentration change, the preset heart rate change, etc., which will be described in more detail in different embodiments. During the setting, it is preferable to use the preset value at the beginning, and then adjust it for each user. For example, the historical data collected by the physiological sensor can be used to help determine the appropriate value for the user. Pre-set conditions, and this dynamic adjustment will help reduce the incidence of false alarms and improve the accuracy of sleep event detection, which is a more advanced method.

The software program can be pre-loaded in the wearable device used to obtain sleep physiological information, or it can be pre-loaded in an external device, such as a personal computer or a smart wearable device, without limitation.

The implementation process starts from step 301. After that, a preset condition is set in step 303. The preset condition is the value at which the warning is activated. In some embodiments, the preset condition can be automatically set in the software program 300 or passed It is set using default values; alternatively, these values can also be determined by the user or medical practitioner and manually input 318, and can be changed based on user-specific information. The threshold conditions/values of the preset condition 303 may include, but are not limited to, various sleep-respiration physiological information and sleep-respiration event-related information, such as the user's blood oxygen level, the user's heart rate, ODI, pulse wave amplitude, etc.

In the learning mode, in step 305, the software program 300 starts to sample the signal, which is collected through the wearable device and transmitted to the software program 300 using data transmission technology known to those skilled in the art. Then, in step 313, The software program 300 collects sample data containing physiological information of sleep breathing, where the sample data is stored in a memory or a database using techniques known to those skilled in the art, and the sleep breathing event is identified in step 314, for example, By analyzing related information about sleep breathing events.

In step 315, the software program 300 compares the identified sleep breathing events with the baseline data 317 of historical sleep breathing events. In some embodiments, historical sleep breathing events are based on The line data 317 may include sleep-respiration physiological information, for example, heart rate and blood oxygen level values provided by medical professionals. The baseline data 317 of historical respiratory events may also provide information indicating the user’s sleep-respiratory events and their initiation. PPG waveforms, heart rate changes, blood oxygen values, and other medical data; in some embodiments, historical sleep-respiratory event baseline data 317 can be obtained from the user’s historical readings, popular sources of sleep-respiratory event baseline data (for example, MIT- BIH polysomnography database), or statistically derived data, etc. In step 315, the sampled data is compared with the historical sleep-respiratory event baseline data 317 to determine whether a false alarm occurs within a certain period of time. If a false alarm is found, the preset conditions are adjusted in step 315 to ensure correct detection For sleep breathing events, if no false alarms are detected, or only a small number of false alarms within the preset range acceptable to the software program 300 or the user are detected, then the preset conditions will not be adjusted in step 315 and the process will be completed State 320.

In the training mode, please go back to step 305. In this step, the software program 300 samples the signal, and then executes the signal processing and corresponding algorithms in step 307 to extract the physiological information of sleep and breathing from the sampled signal. After step 307, the software program 300 continuously checks in step 309 and compares the result obtained in step 307 with the preset condition set in step 303 to determine whether it matches the preset condition. If it does not match the preset condition in step 309, the signal sampling continues without performing further processing. If it matches the preset condition in step 309, a warning action is determined to initiate the generation of the warning 312. Here, the The warning will wake the user briefly, and then the user will take a few deep breaths and return to sleep, thus stopping the apnea/hypopnea condition. Throughout the training mode, the process of monitoring, warning (and adjusting preset conditions) will continue, and the result of this process will gradually reduce the frequency and number of sleep apnea/hypopnea.

The learning mode and the training mode can be dynamically switched automatically or manually set by the user, and can be executed on the same night or on different nights to optimize the treatment effect without limitation.

Next, this system provides content about evaluating and improving postural sleep-disordered breathing.

Please refer to Figure 4. This flowchart illustrates the main steps of using this system to evaluate the relationship between sleep posture and snoring, and provides related training methods. In step 402, the device is set on the user through a wearable structure.

In step 405, when the device wear setting is completed, the control unit starts data collection to obtain sleep posture related information during the user’s sleep. The collected data can be transmitted to an external device through the wireless communication module, or can be first Stored in the memory of the wearable device, and then transmitted to the external device for subsequent analysis. Then, please refer to step 410. In this step, information about the snoring event will be collected. The sensors that can be used include, but It is not limited to a microphone, a piezoelectric vibration sensor, and an accelerometer, which can be installed on a wearable device, or can also be installed on an external device, such as a smart phone, without limitation.

Then, in step 415, the sleeping posture related information and the snoring event related information are combined with each other, and the correlation between the two is calculated through a software program. For example, the reclining snoring index is defined as the number of snoring events per hour in the reclining position. The supine snoring index is defined as the number of snoring events per hour in the supine position, and the snoring index = supine snoring index + non- supine snoring index. In addition, supine-dependent snorers are defined as supine snoring The index is higher than its non-supine snoring index. In step 418, a predetermined threshold is compared with, for example, the ratio of the supine snoring index and the non- supine snoring index, or other values. If the threshold is exceeded, the user is identified as a positional snorer. ), and then sleep position training (SPT) can be performed in step 425. Otherwise, the user can perform sleep breathing physiological feedback training based on the snoring event in step 430; or alternatively, if it is a high posture If high position dependency is accompanied by a high non-supine snore index, the user can combine at the same time to perform posture training during the supine posture and perform snoring event-based during the non-supine posture Sleep breathing physiological feedback training both. On the other hand, if it is a high snoring index with low posture dependence, the user can check whether it is postural sleep apnea (POSA) through step 440, because according to research, when the user’s snoring index is higher , The more often it is found that it has nothing to do with posture, which means that it is a more serious upper airway obstruction that may cause OSA symptoms.

Next, please refer to Figure 5. This flowchart illustrates the main steps of using this system to assess the relationship between sleep posture and sleep breathing events, and provides corresponding training methods. Here, the sleep breathing events can be included or not. Including snoring incidents. In step 502, the device is set on the user through a wearable structure.

In step 505, when the device wear setting is completed, the control unit starts data collection to obtain sleep posture related information during the user’s sleep. The collected data can be transmitted to an external device through a wireless communication module, or can be first Stored in the memory of the wearable device, and then transferred to the external device for subsequent analysis. Then, please refer to step 510. In this step, the physiological information of sleep breathing will be collected. The sensors that can be used include, but It is not limited to light sensors, accelerometers, piezoelectric vibration sensors, piezoelectric motion sensors, breathing air sensors, microphones, etc. Depending on the signal obtained, the sensor can be installed on the wearable On the device, or can also be set on an external device, such as a smart phone, there is no limitation.

Then, in step 515, the sleep posture related information and the sleep breathing physiological information are combined with each other to calculate the correlation between the two through a software program. For example, the sleep respiratory event index is defined as the sleep respiratory event per hour when lying on the back. The number, non- supine sleep respiratory event index is defined as the number of sleep respiratory events per hour in non- supine position, and sleep respiratory event index = supine sleep respiratory event index + non- supine sleep respiratory event index, in addition, postural sleep Respiratory event users are defined as having a supine-sleep respiratory event index higher than their non-supine-sleep respiratory event index. In step 518, a predetermined threshold is compared with, for example, the ratio of the supine sleep respiratory event index to the non- supine sleep respiratory event index, or other values. If the threshold is exceeded, the user is identified as postural sleep The user can perform sleep posture training (SPT) in step 525, otherwise, the user can perform sleep breathing physiological feedback training based on the sleep breathing event in step 530; or, alternatively, if it is high If high position dependency is accompanied by a high non-supine respiratory event index, the user can combine at the same time to perform posture training during the supine posture and during the non-supine posture Based on sleep breathing events, sleep breathing physiological feedback trains both.

Among them, the posture training method is that when it is detected that the sleeping posture meets a preset posture range, for example, the lying posture, and continues for a period of time (for example, 5 to 10 seconds), the warning unit will activate the warning, for example, Vibration or sound, and the alert will gradually increase/increase in intensity until it detects that the sleeping posture is out of the preset posture range, for example, it changes to a different sleeping posture or a non-spine posture, the alert stops immediately. Preset period (for example, adjustable 10 seconds to If no posture change is detected after 60 seconds), the alert will pause and restart after a period of time (for example, a few minutes that can be adjusted); in some embodiments, the initial frequency/duration of the alert will be It is very short and gradually increases until the user no longer presents a lying position; regardless of the strength of the warning, there will be repeated several times (for example, 6 times) with an interval between warnings (for example, 2 seconds).

As for the setting of the preset posture range, it can be different according to actual needs. For example, according to the definition of the lying posture, the preset posture range will be changed, for example, when the accelerometer is set on the torso , Can be set as the normal line of the torso plane and the normal line of the bed surface in the range of plus or minus 30 degrees, or when the accelerometer is set on the forehead, because the head may have more movements, it can be set as the forehead plane normal The corner of the bed is within the range of plus or minus 45 degrees with the normal of the bed surface, or, when the accelerometer is installed on the neck, it can have the same setting range as the head. Therefore, there are no restrictions and various options.

In addition, the posture training performed for snoring is similar to the above-mentioned situation, except that the basis for providing a warning is whether snoring is detected, which is not repeated here.

The warning is provided in that the control unit is constructed to generate a driving signal, and after receiving the driving signal, the warning unit generates at least one warning and provides the at least one warning to the user to achieve sleep posture training And/or the purpose of sleep breathing physiological feedback training, wherein the driving signal is implemented at least according to the sleep posture related information and a preset posture range, and the sleep posture related information meets the preset posture range, and /Or generated based on a warning behavior determined when the sleep breathing physiological information is compared with a preset condition and the at least one sleep breathing physiological information meets the preset condition. How to provide warnings and details are further described in the following embodiments.

Here, it should be noted that the above-mentioned warning unit, regardless of the type of warning generated, such as vibration or sound, has various possibilities for implementation. For example, it can be installed in a wearable device that obtains sleep physiological information. It can also be installed in another wearable device or in an external device, so there is no limitation.

In addition, the provision of warnings is preferably executed after confirming that the user has fallen asleep, in a manner that least disturbs sleep. For this point, in a preferred embodiment, this case uses the detection of sleep physiological Information to understand whether the user has fallen asleep, and the system does not enter Entering a warning can generate a state and start to provide sleep posture training and/or sleep breathing physiological feedback training.

During execution, the sleep physiological information obtained by the physiological sensor will be compared with a preset condition to determine whether the user meets a preset sleep breathing condition. Here, the preset sleep breathing condition is Physiological conditions that occur after falling asleep, for example, whether there are oxygen desaturation events, low oxygen level events, heart rate changes, sleep breathing events, snoring events, sleep apnea events, sleep apnea events, specific changes in breathing, and/ Or a specific change in heart rate, and when the user meets the preset sleep breathing condition, the system enters an alert generation state, and the control unit generates a driving signal to drive the alert unit to provide alerts according to different alert behaviors.

For example, snoring can be detected as a benchmark, for example, using a microphone or accelerometer. In particular, obstructive sleep apnea almost always occurs before snoring occurs, and this pair performs sleep posture training or sleep breathing physiological feedback In terms of training, they are all time points that can be followed, which is quite advantageous; it can also obtain sleep-related information by analyzing the heart rate. For example, the heart rate will have a specific change when sleeping, or the HRV (heart rate variability) can be calculated based on the heart rate Rate) to understand the state of the body; it is also possible to know whether to fall asleep by analyzing breathing, for example, the breathing rate will slow down after falling asleep, etc.; it is also possible to know whether to fall asleep by understanding the stage of sleep, for example, by analyzing acceleration The physical activity (actigraph) measured by the device and/or the heart rate obtained by the light sensor can be used to understand the sleep stage; alternatively, the detection of a sleep breathing event can also be used as a reference for falling asleep. Therefore, there are many possibilities in the choice of physiological sensors. All the physiological sensors that can obtain sleep physiological information can be used without limitation.

In addition, the physiological sensor used to obtain the physiological information to determine whether the system enters the warning-generating state can also be set at different positions according to actual needs, and can be implemented as direct use of the training procedure used The physiological sensor can also be an additional physiological sensor, for example, an accelerometer, light sensor, microphone, etc. in a device worn on the body can be used, or a wearable device can be additionally provided. You can also use a microphone placed in an external device beside the bed, or you can use an accelerometer installed on a mattress. There are various possibilities, all of which are available.

Further, as shown in the flowchart shown in FIG. 7, sleep posture training and sleep breathing physiological feedback training can also be performed together during the same sleep period. In this case, by setting up a posture sensor and at least one physiological sensor, it is possible to obtain sleep posture related information and sleep respiration physiological information during the same sleep period. Here, according to the desired sleep respiration physiological information Depending on the choice of location, the at least one physiological sensor can be, for example, a light sensor, a microphone, an accelerometer, a piezoelectric motion sensor, a piezoelectric vibration sensor, a RIP sensor, and/ There is no limit to the breathing and flu sensor, and in particular, when an accelerometer is selected as a physiological sensor, it can also be used as a posture sensor at the same time.

Then, the sleep-respiration physiological information analysis program is used to compare the sleep-respiration physiological information with preset conditions to determine the sleep-respiration event of the user, and the sleep posture analysis program is used to compare the sleep posture related information with the preset posture The range is compared, wherein when the sleep posture related information meets the preset posture range, a first warning condition combination is provided, and when the sleep posture related information exceeds the preset posture range, a second warning condition combination is provided , And the warning determination program determines the warning behavior according to different warning condition combinations. Therefore, the control unit generates a driving signal according to the warning behavior, and the warning unit generates at least one warning after receiving the driving signal to achieve impact The sleeping posture of the user and/or the effect of affecting the sleeping breathing state of the user.

Wherein, the first warning condition combination may include at least one of a time range condition and a sleep breathing event condition. For example, the time range condition can be implemented based on absolute time, for example, 1 AM; it can also be implemented It is based on specific physiological conditions, such as 1 hour after lying down, falling asleep, or various other physiological conditions; it can also be implemented as a delay time, for example, after 1 hour after the device is activated, so that it can be based on The actual time needs to choose whether to provide warnings in the context of the preset posture range, which helps to provide a more comfortable experience. In addition, the sleep breathing event conditions provide whether to perform sleep posture training together during the same sleep period As well as the choice of sleep breathing physiological feedback training, the training effect is further improved.

In addition, the second warning condition combination will at least include the time range condition and the sleep breathing event condition. For example, when the sleep posture related information exceeds the preset posture range, for example, when in a non-recumbent state, The most important condition for warning is the occurrence of sleep Inhalation event, and similarly, as mentioned above, it is possible to select the time to perform sleep breathing physiological feedback training, for example, using absolute time as a reference, or specific physiological conditions as a reference, or setting a delay time.

Furthermore, other conditions can be added, such as warning intensity conditions, warning frequency conditions, etc., to provide a weaker warning when you just fall asleep, and then increase the intensity after a period of time. Therefore, the combination of warning conditions is provided , Which can better meet the needs and make users feel less disturbed to perform training.

Moreover, since the sleeping posture changes at any time during sleep, the first warning condition combination and the second warning condition combination will be dynamically applied, and the order of application is not limited.

In this case, the system will have various software programs according to the different functions executed, including, but not limited to, sleep physiological information analysis program, sleep respiratory physiological information analysis program, sleep respiratory event analysis program, alarm determination program, etc., Various physiological information can be obtained based on the physiological signals obtained by the physiological sensor, and without limitation, various software programs can be pre-loaded in different devices according to actual needs and implementation methods.

According to the above-mentioned sleep breathing physiological feedback training based on the physiological information of sleep breathing (Figure 3), and the sleep breathing disorder detection and training based on sleep posture (Figure 4 and Figure 5), the relevant physiology can be obtained in cooperation The various possible placement positions of the physiological sensor of the signal (as shown in Figure 2), this case has the following implementation possibilities without limitation. Therefore, the various training contents and combinations mentioned above can be determined by any of the following descriptions A suitable embodiment is implemented, that is, the details are not repeated here.

First of all, one aspect of this case is to assess the relationship between the user's sleep posture and sleep disordered breathing, and further on how to improve postural sleep disordered breathing.

On the one hand, the idea is to achieve the best use effect through scattered settings.

When a decentralized form is adopted, how the decentralized devices communicate with each other and/or how to communicate with external devices becomes very important, because it not only involves the feasibility of implementation, but also the convenience of use, and this case The decentralized system refers to, including a plurality of independent operation Each device has a circuit configuration such as a control unit, a power module, and a communication module. The communication module can be further implemented in a wireless form. At this time, the devices use digital signals and communicate in a wireless form to maximize Ease of use.

As mentioned in the technical background, most of the conventional technologies use a single device to detect sleep physiological information and provide warnings at the same time. However, since the position of the sleep posture is preferably near the central axis of the body, or can be calculated by conversion. Therefore, it is easy to cause the detection and warning to be incompatible.

When using a decentralized form, first of all, the location of the warning unit and the form of the warning become freely selectable. For example, some people are more sensitive to vibration, and some people are more sensitive to sound; or, different body parts are more sensitive to The sensitivity of warnings is also different.

Furthermore, the decentralized form also allows more options for obtaining sleep physiological information. As mentioned above, various physiological sensors can be used to obtain sleep physiological information and can be set in various positions. Therefore, the use of decentralized forms will help make the measurement closer to actual needs, for example, sleep breathing of different users The symptoms of the disorder may be different, and the actual physiological conditions can be more accurately reflected through selection. In addition, different users' habits can also be responded to. For example, each person has different feelings about the body set objects, and they are not bound. The design allows users to choose the setting position that least disturbs sleep.

Among them, one implementation may be that a sleep system is implemented to include two devices, a sleep warning device and a sleep physiological device. The sleep warning device includes a first wearable structure, a first control unit, and at least a microcontroller/ A processor, a first wireless communication module, electrically connected to the control unit, a warning unit, electrically connected to the control unit, and a power module, wherein the first wearable structure is used to set the sleep warning device On a user so that the warning unit generates at least one warning for the user; in addition, the sleep physiology device includes a second wearable structure, a second control unit, at least a microcontroller/processor, and a second Two wireless communication modules, electrically connected to the control unit, a posture sensor, electrically connected to the control unit, and a power module, wherein the second wearable structure is used to set the sleep physiological device in the use So that the posture sensor can obtain sleep posture related information during the sleep of the user, and serve as a reference for providing the at least one warning.

The above-mentioned sleep system is a decentralized sleep posture training system. Through this setting, the warning unit can be freely selected in the form of vibration or audio, and set in any suitable position. In addition, posture sensors are not required. The accommodation must be placed in a body position where the warning can be felt, and can be placed in any suitable position on the body.

Among them, in particular, the sleep physiology device used to obtain a sleeping posture can be implemented to be installed on the torso, for example, abdomen, chest, etc., and can be implemented to be installed on the torso using straps, adhesive structures, etc., or can also be implemented It is fixed on clothes, and since the information about sleeping postures can be obtained without touching the skin, the device can also be installed outside the clothes, which is quite convenient. In addition, the sleep warning device can be implemented in general users. The wearing position, for example, wrist, fingers, etc., and adopt the form that is widely accepted by users, for example, wrist-wearing form, finger-wearing form, etc., to provide vibration warning; the combination of the two is very convenient to use, but also The body is not burdened. For example, the sleep physiology device can be installed on the chest and the sleep warning device can be installed on the wrist.

Of course, without limitation, the sleep physiology device can also be installed in other positions, such as forehead, neck, etc., and the sleep warning device can also be installed in other positions and adopt other forms of warning, for example, it can be implemented as a configuration It is used to provide sound warnings near the ears and/or ears, and can be further implemented as earphones connected to external devices. For example, the external devices can communicate with the sleep physiology device, and then drive the connection according to the sleep posture provided by the sleep physiology device The earphone generates a sound warning; further, the sleep warning device can also be implemented in the form of a smart earphone, that is, it can directly communicate with the sleep physiological device wirelessly. Therefore, there are various implementations according to actual needs ,no limit.

As for how the acquired physiological information is transmitted between dispersed devices, there are many options. For example, in a preferred embodiment, the sleep physiological information analysis program and the alarm determination program can be preloaded in the sleep physiological device That is, the sleep posture-related information is first compared with a preset posture range to learn whether the sleep posture-related information meets the preset posture range, and a warning action is determined when it meets the preset posture range, After that, the warning behavior is transmitted to the sleep warning device through a digital signal. After receiving the digital signal, the control unit in the sleep warning device generates a driving signal according to the warning behavior, and then drives the The warning unit generates at least one warning and provides it to the user to achieve a warning effect, for example, to cause the user to spontaneously change posture. This method will help save the power consumption of the sleep warning device. For example, if the battery needs to be replaced, the battery replacement cycle can be extended.

Alternatively, it can also be implemented that the sleep warning device receives the sleep posture related information from the sleep physiological device, and uses the preloaded program to analyze and determine the provision of the alert. In this case, the sleep posture related information is first transmitted through the digital The signal is sent to the sleep warning device and compared with a preset posture range to determine the warning behavior. After that, the control unit of the sleep warning device generates a driving signal according to the warning behavior, and then drives the warning unit to generate at least one A warning is provided to the user to achieve a warning effect; or, alternatively, it can be implemented as the sleep posture related information is analyzed in the sleep physiology device to determine whether it meets the preset posture range, and then through The digital signal transmits the comparison result to the sleep warning device and determines the warning behavior. After that, the control unit of the sleep warning device generates a driving signal according to the warning behavior, and then drives the warning unit to generate at least one warning for the user , In order to achieve the warning effect. Therefore, there are various implementation possibilities, which can be changed according to actual needs without limitation.

When there is an external device, there are more choices. For example, the sleep physiological information analysis program and the warning determination program can be pre-loaded in the external device. In this case, the sleep physiological device obtains sleep posture related information , Will be sent to the external device, and then the external device will execute the sleep physiological information analysis program and the warning determination program to determine whether and how to provide the warning, and send the warning behavior to the sleep warning device through a digital signal, and After receiving the digital signal, the control unit of the sleep warning device generates a driving signal to drive the warning unit to provide warning; alternatively, only the sleep physiological information analysis program or only the warning determination program can be preloaded externally In the device, therefore, it can be changed depending on the actual operation process and actual needs, without limitation.

Further, physiological sensors can also be added to obtain other physiological information of sleep breathing. On the one hand, it can be used to confirm the effect of performing sleep posture training, for example, whether the number of sleep breathing events is reduced, and on the other hand, it can also be used as an implementation The basis of sleep breathing physiological feedback training is to be performed together with sleep posture training during the same sleep period to increase the effect. For example, it can be set on a sleep physiological device and set in different body axis positions according to the sleep physiological device For example, when the device is installed on the forehead, optical sensors, accelerometers, microphones, piezoelectric vibration sensors, etc. can be used to obtain blood oxygen concentration, heart rate, snoring related information, etc.; When the device is installed between the nose and mouth, it can use respiratory airflow sensors, light sensors, accelerometers, microphones, piezoelectric vibration sensors, etc., to obtain respiratory airflow changes, heart rate, snoring related information, etc.; When set on the torso, light sensors, accelerometers, microphones, piezoelectric motion sensors, etc. can be used to obtain heart rate, snoring-related information, breathing movements, etc.; in addition, additional physiological sensors can also be set for sleep warning On the device, or an external device, and select a suitable physiological sensor according to the setting position, without limitation. The above physiological information of sleep breathing can be further used to derive sleep apnea events, sleep apnea events, oxygen desaturation events, low oxygen level events, heart rate changes, sleep breathing events, snoring events, etc., so there is no limit. .

In the following description, the content of the distributed architecture is a wireless distributed architecture composed of multiple devices that can operate independently. If wireless communication is performed between each device, the situation is similar. Therefore, the above-mentioned related to different devices And/or information transmission methods with external devices, analysis of information, decisions on warning behaviors, and other implementation options are also applicable, so I won’t repeat them here.

In addition, it should also be noted that, as is well known to those with ordinary knowledge in the field, the operation of each device in a wireless distributed system must have basic control units, wireless communication modules and/or wired communication modules, power modules, etc. The circuit configuration, and since these are repetitive content, in the description of all the following embodiments, it will be omitted without repeating it, and the actual circuit configuration of all devices in this case is not limited thereby.

Then, another implementation may be that a sleep system is implemented to include two devices, a sleep warning device and a sleep breathing physiological device, both of which are set on a user through a wearable structure, wherein the sleep warning device has The posture sensor is used to obtain the user's sleep posture related information, and the warning unit is used to provide at least one warning to the user, and the sleep breathing physiological device has a physiological sensor to obtain the user’s sleep during sleep Sleep breathing physiological information; in this example, since sleep posture can be obtained, sleep breathing physiological information can also be obtained, so whether it is postural sleep breathing disorder or non-postural sleep breathing disorder, it can be obtained in this system Solving is equivalent to combining sleep posture training and sleep breathing physiology Both feedback training can comprehensively improve sleep-disordered breathing. Advantageously, the warning unit in the sleep warning device can selectively generate warnings based on different sleep physiological information, for example, based on sleep posture related information Alarms can be generated based on the physiological information of sleep breathing, and can also be generated based on both sleep posture related information and sleep breathing physiological information, which is equivalent to providing a double effect for any type of patient or mixed symptoms For patients, or for those who don't know what type of patient they are, they can effectively provide solutions, which is quite advantageous.

Wherein, the sleep posture related information is compared with a preset posture range to find out whether it meets the preset posture range, and the sleep breathing physiological information is compared with a preset condition to find out whether it conforms to the preset Conditions, therefore, the decision of warning behavior can be based on one of the two or a comprehensive consideration of both, there is no limit.

Furthermore, such a system can also have different modes of operation. Since the sleep warning device itself has a posture sensor and a warning unit, it can be used alone for sleep posture training, or it can work with the sleep breathing physiological device to increase the effect, so that it can be used Another option is to choose how many devices should be installed on the body, and which sleep physiological information should be selected as the basis for warning. And this is also the advantage that a decentralized design will have.

Wherein, when the sleep warning device is implemented on the torso, it is better to adopt a vibration warning method, and when it is installed on the forehead or neck, it can choose to use vibration warning or sound warning, without limitation.

Furthermore, the advantage based on the dispersed form is that the type and location of the physiological sensor, as well as the type of sleep-respiratory physiological information obtained, can be selected in different ways. Therefore, it is used to determine The preset conditions will also vary with the selected physiological sensor, and the wearing structure used to set the sleep breathing physiological device will also vary.

For example, the sleep-respiratory physiology device can selectively adopt various implementations that are integrated into general living habits, such as wrist-worn or finger-worn, and can use light sensors or microphones to obtain sleep-respiration physiological information. For example, heart rate, blood oxygen concentration, respiratory behavior, snoring related information, changes in breathing sound, etc. In this case, smart wearable devices, such as smart hands Watches, smart bracelets, smart headphones, etc., are suitable for use in this situation. In addition, they can also be implemented as non-wearable forms placed near the body. For example, the microphone in a smart phone can be used to detect snoring and breathing sounds. Obtain sleep respiratory physiological information, and according to the obtained sleep respiratory physiological information, the sleep respiratory event analysis program can further obtain various sleep respiratory events, such as oxygen desaturation events, low oxygen level events, heart rate changes sleep respiratory events , Snoring events, sleep apnea events, and sleep apnea events, etc., so there are various possibilities without limitation. In this way, you only need to pair with the sleep alert device installed on the torso/head/neck to provide sleep posture detection and vibration alert. The sleep system that provides two training methods can be integrated with devices used in ordinary daily life. Together, it has considerable advantages in terms of popularity. For example, the sleep alert device can be placed on the forehead and the sleep-respiratory physiological device can be placed on the fingers. In addition, the sleep alert device can also be placed on the neck and the sleeper. The respiratory physiological device can be implemented as a smart phone, so there are various possibilities.

Another implementation may be that a sleep system includes two devices, a sleep warning device and a sleep breathing physiological device, both of which are set on a user through a wearable structure, wherein the sleep warning device has a warning unit, In order to provide at least one warning to the user, the sleep breathing physiological device has a physiological sensor to obtain at least one sleep breathing physiological information of the user during sleep, and through wireless communication, the sleep breathing physiological device The acquired physiological information of sleep breathing is used as the basis for the warning unit to generate a warning, wherein the physiological information of sleep breathing is used as the basis to derive at least one sleep breathing event, and determine a warning behavior, and the warning behavior is generated A driving signal of, will drive the warning unit to generate at least one warning and provide it to the user to achieve the warning effect, for example, to let the user be briefly awakened and resume normal breathing function.

The above-mentioned sleep system is a decentralized form of sleep breathing physiological feedback training system, and through this setting, the warning unit can be freely selected as a tactile or auditory form, and set in any suitable and effective position for feeling the warning. In addition, the types of physiological sensors and the sleep-respiratory physiological information to be obtained can also be freely selected. For example, different users have different sleep-disordered breathing conditions, and the suitable physiological sensors are also different. Therefore, through the decentralized design, The application range becomes wider and more flexible. For example, the physiological sensor can be implemented as, for example, a light Sensors, accelerometers, respiratory and flu sensors, piezoelectric motion sensors, impedance detection electrodes, piezoelectric vibration sensors, and/or microphones, and are installed on, for example, the head, ears, and neck To obtain the physiological information of sleep and breathing including, but not limited to, snoring-related information, changes in breathing sound, breathing movements, changes in respiratory airflow, breathing behavior, heart rate, blood oxygen concentration, etc., In turn, various sleep breathing events are determined, such as oxygen desaturation events, low oxygen level events, heart rate changes, sleep breathing events, snoring events, sleep apnea events, and sleep breathing hypopnea events.

Furthermore, the sleep breathing physiological device may further include a posture sensor to obtain sleep posture related information. In this way, it provides options for sleep posture training and/or sleep respiration physiological feedback training. In this case, It is necessary to pay attention to choosing the setting positions such as the head, neck, torso, etc. that can obtain the sleeping position.

In particular, in a preferred embodiment, the sleep warning device can choose to adopt tactile warning and be arranged on the wrist to increase the convenience of use. More conveniently, it can directly use various common wearables with vibration function in the market. Devices, such as smart watches, smart bracelets, etc., are used as warning devices, and can also directly use the information providing interface on the wearable device to provide various information. It will be a very cost-effective choice for users. Of course The information providing interface on an external device, such as a smart phone, can also be used without limitation.

Furthermore, another implementation may be that a sleep system includes two devices, a first sleep physiological device has a first sleep physiological sensor to obtain a first sleep physiological information, and a second sleep physiological device has A second sleep physiology sensor to obtain second sleep physiology information, and further, at least one warning unit can be implemented to fall into the first sleep physiology device and/or the second sleep physiology device to be based on sleep physiology Information provides a warning, and through wireless communication, the warning unit can be implemented to provide a warning based on the first sleep physiological information, the second sleep physiological information, or the first sleep physiological information and the second sleep physiological information.

Wherein, the first sleep physiology device and the second sleep physiology device are implemented in a wearable form, and the physiological sensors used and the available sleep physiological information are also different according to the different positions. For example, the positions that can be set include, but are not limited to, the head, neck, trunk, upper limbs, etc., and physiological sensors that can be used include, but are not limited to Made in, light sensors, accelerometers, breathing air flu sensors, impedance detection electrodes piezoelectric motion sensors, piezoelectric vibration sensors, microphones, brain electrodes, eye electrodes, and electromyography electrodes, And the available sleep physiological information includes, but is not limited to, snoring-related information, changes in breathing sound, breathing movements, changes in respiratory airflow, breathing behavior, heart rate, blood oxygen concentration, brain signals, eye signals, myoelectric signals, Sleep posture, sleep physical activity, and sleep stage, as well as sleep breathing events that can be derived include, but are not limited to, oxygen desaturation events, low oxygen level events, snoring events, heart rate changes, sleep breathing events, sleep apnea events, And sleep apnea hypopnea events. That is, in this implementation possibility, the decision of warning behavior will have various possibilities without limitation, for example, you can choose snoring-related information with blood oxygen concentration, or heart rate with blood oxygen concentration, or sleeping posture with breathing movement, etc., or , The warning behavior can also be determined based on a single sleep physiological information, while the other is used to understand the physiological state during sleep. Therefore, there are various possibilities without limitation.

For example, in a preferred embodiment, the first sleep physiology device can be installed on the wrist, and use light sensors, accelerometers, and/or microphones to obtain heart rate, breathing behavior, snoring related information, and breathing Acoustic changes, physical activity during sleep, and/or sleep stages, and the second sleep physiological device is placed on the finger, and the blood oxygen concentration is obtained by the light sensor. In this way, two types of sleep can be obtained on the same upper limb Physiological information is quite advantageous.

Of course, in addition to the above-mentioned implementation exceptions, the first sleep physiological device and the second sleep physiological device can also be set in any wearable position according to actual use needs, such as head, ears, torso, arms, wrists, fingers Etc., in order to use the same or different physiological sensors to obtain more sleep physiological information.

In addition, in particular, when one of the first sleep physiology device and the second sleep physiology device is implemented to obtain a sleep posture, the warning unit will be based on sleep posture related information and/or sleep breathing physiological information. Provide warnings to perform sleep posture training and/or sleep breathing physiological feedback training. On the other hand, if both the first sleep physiological device and the second sleep physiological device are implemented to obtain sleep breathing physiological information, the warning unit is based on At least one of the two kinds of sleep breathing physiological information provides a warning, so that the two kinds of sleep breathing physiological information can be complementary.

Furthermore, when the wearable form used is the same as that of smart wearable devices used daily, for example, wrist wear, ear wear, etc., smart wearable devices can also be used to achieve the above behaviors, which is quite convenient in use; in addition, the Those with a warning unit in the first sleep physiology device and the second sleep physiology device can further choose to be used alone to perform training for sleep-disordered breathing, or they can choose to work together with another device to provide more functions .

In addition, in addition to training to improve sleep-disordered breathing, the decentralized system can also be applied to the assessment of sleep-disordered breathing to make the assessment results more accurate.

One implementation may be that a sleep system is implemented to include two devices, a sleep physiology device and a sleep respiration physiology device. The sleep physiology device has a posture sensor and is arranged on the user's body to obtain sleep during sleep. The posture, and the sleep-respiratory physiological device has physiological sensors to obtain sleep-respiratory physiological information, and through the decentralized design, whether it is sleep posture-related information or sleep-respiratory physiological information, it can be more accurate and appropriate The advantage of obtaining the position of the sleep position is that it will flexibly provide different physiological information of sleep and breathing for different physiological conditions. For example, since it is no longer limited to the position to obtain the sleep position, it can be freely selected Detecting snoring events, you can also choose to detect oxygen desaturation events, or other sleep breathing events, no matter which can be accurately assessed, and then combined with sleep posture analysis, naturally can more accurately determine the occurrence of sleep breathing During the event, the proportions that meet the preset posture range and exceed the preset posture range, for example, the proportions during lying and non-spine periods, can provide users with, for example, information about the posture related information of sleep breathing events through the information providing interface , And then understand whether the correlation between the occurrence of sleep breathing events and sleep posture is high or low.

Moreover, similarly, this configuration also enables the smart device to be further used as the sleep-breathing physiological device for the detection of sleep-breathing physiological information. For example, the light sensor and microphone on the smart watch can be used. Or a microphone on a smartphone, etc. Advantageously, since this system focuses on assessing whether there is sleep breathing disorder and its relationship with sleep posture, the provision of information is particularly important, so smart devices can be naturally used The existing information providing interfaces on the above, such as screens, LEDs, sound components, etc., are used as the information providing interfaces of this system. For example, smart wearable devices, such as smart watches, smart bracelets, and display components can be used. You can also use the display elements on your smartphone, and this configuration not only It is simple and convenient, and is also in line with the daily use behavior of users.

For example, in actual use, a sleep physiology device can be installed on the torso of the body, and then the sleep breathing physiology device can be installed on the fingers to obtain the blood oxygen concentration and the ODI that can be further calculated by the light sensor, or also It can be set on the wrist to use the light sensor to obtain the average blood oxygen concentration change, heart rate, breathing behavior, or use the microphone to obtain various sleep breathing related physiological information such as snoring information, so as to know the occurrence of sleep breathing events and sleep posture In addition, the ear is also a very suitable setting position. The light sensor can be set, and the blood oxygen concentration can be obtained according to the PPG signal obtained by the different setting position, and the breathing behavior, heart rate, etc. can also be obtained. Microphone to obtain the sound produced by snoring, or the accelerometer to obtain the vibration produced by snoring, and a respiratory flu detector can also be installed between the mouth and nose to understand whether a sleep apnea event and/or sleep apnea event occurs . Therefore, there are various possibilities for setting positions without limitation.

Among them, when choosing to set on the body to obtain physiological information, the wearable structure can be used for setting, such as adhesion structure, strap, head-wearing structure, finger-wearing structure, wrist-wearing structure, ear-wearing structure, etc., and both can be used simultaneously. The wearing structure can be changed according to the actual implementation situation without limitation.

Furthermore, a warning unit can also be provided in the system, for example, in a sleep physiology device, and/or sleep respiration physiology device, to improve sleep breathing disorder, for example, if you find sleep breathing during lying on your back If the event rate is higher, warnings can be issued during lying on their backs. For example, the vibration module generates vibrations to achieve spontaneous sleep posture changes, thereby improving postural sleep apnea/hypopnea, snoring, and/or also Alerts on sleep breathing events derived from the analysis of sleep breathing physiological information. For example, when a snoring event occurs, or when an oxygen desaturation event occurs, the sleep breathing physiological feedback training is performed. In this case, the system becomes Both evaluation and training improvement procedures can be taken into account at the same time. For example, at the beginning, the user may not execute the warning first, but use two devices to evaluate before sleep to know the presence or absence of sleep disordered breathing and its Afterwards, when it is found that the occurrence of sleep breathing events is indeed highly correlated with the sleeping posture, for example, when lying on your back, there is a higher incidence. At this time, you can further use the system to improve training functions. To perform sleep posture training, Or if you find that the correlation between sleep breathing events and sleep posture is low, you can choose to perform sleep breathing physiological feedback training, which is equivalent to a system that can provide multiple functions, which is very advantageous.

Another implementation may be that a sleep system is implemented to include two devices, a sleep warning device and a sleep breathing physiology device. The sleep warning device has a posture sensor and is set on the user's body to obtain sleep during sleep. The posture and the warning unit are used to provide at least one warning to the user. The sleep breathing physiological device has a physiological sensor to obtain the sleep breathing physiological information of the user during sleep. In this configuration, first, the Since the sleep warning unit can provide warnings, it can be used alone to provide warnings according to sleep posture, that is, to provide sleep posture training, and further, when used with the sleep breathing physiological device, the sleep breathing physiological device The acquired physiological information of sleep breathing can be used to confirm the effect of providing warnings, for example, whether the occurrence of sleep breathing events such as sleep apnea and snoring is reduced due to changes in sleep posture. In this way, through the information providing interface Knowing all kinds of related information, such as the number and time point of warning execution, the distribution and proportion of different sleep postures, the number and time point of sleep breathing events, etc., the user will be able to clearly know the sleep posture performed Whether the training is effective and what is the effect is also quite advantageous.

In addition, in order to understand the difference between before and after the use of sleep posture training, it can also be implemented as that the warning unit in the sleep warning device does not provide a warning at first, but only obtains the user’s sleeping posture, and then cooperates with the sleep breathing physiological The device obtains the physiological information of sleep breathing during sleep and combines the two to know the relationship between the occurrence of sleep breathing events and different sleep postures. In this way, when the sleep posture training is started, further warnings can be obtained The effect of whether or not, for example, the ratio of different sleep postures, and whether the occurrence of sleep breathing events is reduced.

Moreover, through this setting, it is equivalent to long-term continuous detection, such as daily use tracking, sleep physiological information during sleep posture training, so the setting values related to warning behaviors can be adjusted according to the obtained sleep physiological information. This can make the provision of warnings more effective, and secondly, it can also minimize the interruption of sleep.

Moreover, because the sleep warning device has a posture sensor and a warning unit at the same time, when the user has been sure that his sleep breathing disorder has a high correlation with his sleep posture, And when it has been confirmed that the provided warning can achieve the improvement effect, the sleep warning device can be used alone to simplify the configuration of the body. After a period of time, for example, once a month, it can be combined with the sleep breathing physiological device again Used together to respond to possible changes in physiological conditions and adjust the content of warning behaviors accordingly to allow the effect of sleep posture training to continue; in addition, because the human body will achieve sleep posture after a period of sleep posture training Habit formation, for example, becoming accustomed to a sleeping position that is not lying on your back. In this case, you can also try to suspend sleep posture training, and only perform the detection of sleep posture and/or sleep breathing physiological information, and then adjust the use situation in accordance with.

In actual use, for example, a sleep warning device installed near the torso, head, or neck of the body can cooperate with a sleep-respiratory physiological device installed on the finger to obtain blood oxygen concentration and ODI through a light sensor. Or it can also cooperate with a sleep-respiration physiological device installed on the wrist to obtain various sleep-respiration-related physiological information such as average blood oxygen concentration changes, heart rate, breathing behavior, etc. through a light sensor for confirmation and/or sleep-respiration physiological feedback training. In addition, the ear is also a very suitable setting position. A light sensor can be set. According to the PPG signal obtained by the setting position, the blood oxygen concentration can be obtained, and the breathing behavior, heart rate, etc. can also be obtained. The microphone can also be set. Obtain the sound produced by snoring, or the vibration produced by snoring by the accelerometer, and a respiratory flu detector can also be installed between the nose and mouth to understand whether a sleep apnea event and/or sleep apnea event occurs. Therefore, there are various possibilities for setting positions without limitation.

In addition to the above-mentioned various possible implementations for obtaining physiological information and providing warnings, the following further elaborates on other related content under the decentralized structure.

First of all, there are also multiple implementation options regarding information provision. For example, the information providing interface can be set on one of the two devices, or both devices have the information providing interface, or using external devices, such as mobile phones, watches, as the information providing interface, and the provided There are also various possibilities for the content of the information, such as sleep posture related information, sleep physiological information, sleep breathing physiological information, sleep breathing events, warning behaviors, warning effects, warning provision time, etc. All kinds of information during sleep are available through The information is provided to the user through the interface without limitation.

Furthermore, the distributed architecture of this case needs to be noted when wireless communication is adopted. What is meant is how to integrate the control between multiple devices in the entire system and how the physiological information obtained by different devices is integrated.

First of all, the control of the system, such as start/end operation, parameter setting, etc., has various possibilities according to different operation methods. For example, it can be operated through an external device, such as loading an application in a mobile phone, and controlling the system through an operating interface and wireless communication; or setting an operating interface on one of the devices and controlling the Another device for wireless communication, etc.; In addition, there are also various possibilities for how to start the system and start operation. For example, in addition to controlling the start through the operation interface, it can also be set to start automatically, for example, because it can be detected It is set on the user's body surface to start automatically, or it can be set to start at a time. Therefore, a suitable method can be selected according to actual needs without limitation.

Then, in terms of information storage, you can choose to directly store the physiological information in the device that obtains the physiological information. In this case, you need to be equipped with a data storage unit, such as a memory. In addition, you can also choose to store the information in a single device, for example, One device wirelessly transmits information to another device and stores it in the memory of the other device; and after the sleep period ends, the stored information can be transmitted wirelessly or wiredly, for example, you can use Wireless communication, such as Bluetooth, or wired communication, such as USB interface, and transfer to external devices, such as mobile phones, computers, etc., can also be used to remove and read the memory card; on the other hand, you can also choose The information of both devices are sent to the external device in real time. For example, the two devices send information to the external device through wireless communication, and then the external device stores the information, or one of the devices sends the information to the other device first After that, they are sent to an external device together. Therefore, there are various implementation possibilities without limitation.

In addition, since various information is obtained by two devices separately before being provided to the user, it is very important how to align the timing of the various information with each other in order to achieve the effect of effectively using the information.

For example, the time axis alignment between the provision of a warning and the sleeping posture is the basis for confirming whether the warning has achieved its effect. For example, it can be known through the comparison between the two whether the provision of the warning has achieved a change in the sleeping posture, and the warning The intensity, frequency, pattern, etc. of the sleep posture are used to achieve the effect of changing the sleep posture; in addition, the relationship between the obtained physiological information and the sleep posture is It is an important basis for confirming whether it is a postural sleep breathing disorder. For example, by analyzing physiological information, you can know whether a sleep breathing event has occurred, and you can further confirm the sleep posture when a sleep breathing event occurs. Therefore, for the distributed sleep system in this case, the timing alignment between various information will be the basis of all analysis and operations.

As for how to perform timing alignment, there are many possibilities. For example, time stamps can be used to complete information integration by aligning the time axis, or time synchronization can also be performed before the entire process starts. There are various possibilities without restrictions, and whether it is used Which method, preferably, is executed while the entire program is started, for example, when the start key is pressed, or when it is started wirelessly by an external device, which makes the operation more convenient.

Here, it should be noted that although the above embodiments are described on the basis of two devices, the content of the distributed architecture of this case is not limited, and it can also be implemented as more devices, for example, three, four Each device can be changed according to actual needs.

Then, another idea is to achieve the effect of providing multiple functions by adapting a single device to different settings, that is, the same device is constructed to be combined with different wear structures or use the same wear The structure is arranged on at least two different positions on the user's body to thereby provide different functions.

First, in assessing sleep disordered breathing, one implementation may be that a sleep system includes a housing and at least one wearing structure, and the housing can be set on different body parts by using the at least one wearing structure, for example, a first A body part and a second body part, wherein, when implemented as having two wearing structures to be respectively disposed on different body parts, the shell and the wearing structure are further implemented in a removable form to facilitate Replaced. In addition, the sleep system will also include a control unit, including at least a microcontroller/processor, a posture sensor, electrically connected to the control unit, and at least one physiological sensor, electrically connected to the control unit, A power module and a communication module. When set on the first body part, the posture sensor and the at least one physiological sensor will simultaneously obtain sleep posture related information and sleep breathing physiological information. In the future, through the mutual analysis and comparison between the two kinds of information, the posture correlation information of the sleep breathing event can be obtained, so that the user can understand the relationship between sleep posture and sleep breathing disorder, that is, the first body part is Falling near the central axis of the body, for example, trunk, head, neck When it is set on the second body part, the at least one physiological sensor will obtain the physiological information of sleep and breathing, that is, the position of the second body part is not limited, for example, it can be the head Department, trunk, upper limbs, lower limbs, etc., any position where physiological information of sleep breathing can be obtained.

The advantage brought by such a structure is that users can decide how to use it according to their own needs, and are not limited to a fixed installation location. General physiological testing devices, especially those that are set up through a wearable structure, have only a single setting position, such as rings, bracelets, watches, etc. In addition, there are indeed differences in the physiological testing requirements during sleep and during daily activities. Therefore, generally speaking, when users have different physiological testing needs, they need to repurchase a different physiological testing device, which is very uneconomical.

Through this system, first of all, when it is set in the first body part, it obtains both sleep breathing physiological information and sleep posture related information. In addition to knowing whether there is sleep breathing disorder, it can also effectively evaluate whether it is postural sleep breathing disorder. Provides the ability to further distinguish the types of sleep-disordered breathing, especially as mentioned above, postural sleep-disordered breathing accounts for a relatively high proportion, which adds to its practicability; in addition, since the setting of the second body part is not limited, therefore, You can choose the position that is easiest to perform, such as the wrist, to understand the breathing situation during sleep. For example, you can set it in the second body part at the beginning of use, and confirm whether you have sleep through the obtained sleep breathing physiological information After that, if you find that you have sleep-disordered breathing, you can move to the first body part and get the physiological information of sleep breathing and sleep posture related information to further confirm whether it is postural sleep-disordered breathing. For the user It is a very practical choice.

There are various possibilities in the selection of the at least one physiological sensor and the body part. For example, you can choose to use a light sensor to obtain blood physiological information such as blood oxygen concentration, heart rate, and/or breathing behavior. In this case, the first body part can be the trunk, forehead, etc., and the second body part It can be fingers, wrists, arms, ears, etc.; or, you can also choose to use a microphone to obtain snoring-related information and/or breathing changes. In this case, the first body part can be the torso, head, etc. The second body part can be fingers, wrists, arms, ears, etc.; alternatively, an accelerometer can also be used. Among them, the first body part can be implemented as head, torso, etc. to obtain heart rate, snoring related information, Physiological information such as breathing movements, Two body parts can be implemented as fingers, wrists and other positions to obtain heart rate. Here, in particular, the physiological sensor implemented as an accelerometer can also be used as a posture sensor at the same time to further simplify the manufacturing process and reduce the cost. Therefore, there are various possibilities without limitation.

Alternatively, when it is installed on the second body part, there can be other options for use. For example, since the location is not limited, it is also suitable for daytime use. For example, fingers, wrists, ears, etc. can be used in sleep During the period, the physiological information of sleep and breathing can be obtained, and meaningful physiological information can also be obtained during the day. For example, the light sensor can obtain blood oxygen concentration, heart rate, breathing behavior, etc., and the accelerometer can provide information on sleep physical activity, sleep stage, daily body Activity information, etc.; in addition, if some users are already using some products that help fall asleep or help solve sleep disordered breathing, such as anti-snoring pillows, chin straps, etc., they can be used to understand the effects of use; therefore, for users , Which is equivalent to providing a machine with multiple functions, and the setting position can be changed according to preference, which is quite helpful to enhance the user's willingness to use.

Therefore, whether it is the choice of the physiological sensor/posture sensor, or the position of the first body part/second body part, there are many possibilities and implementation combinations, which are not limited to the above, and multiple embodiments can be Replacing each other is within the scope of this case.

Furthermore, further, a warning unit can be added to the above sleep physiological system, and then applied to improve sleep-disordered breathing. For example, when it is installed in the first body part, since the sleeping posture can be obtained, the sleep can also be obtained. Respiratory physiological information. Therefore, in addition to the use of the warning unit to perform sleep posture training, the sleep respiration physiological information can also be used to monitor the effects of sleep posture training, for example, whether the sleep disordered breathing is reduced due to the reduced proportion of lying on the back , Which is helpful for users to gain further understanding, or, furthermore, can also adjust warning behaviors by monitoring the physiological information of sleep and breathing, for example, adjust related settings; in addition, there are other implementation options, For example, when you are in the first body part, you can further generate a warning based on the obtained sleep breathing physiological information to perform sleep breathing physiological feedback training, so that when you are in the first body part, it can be based on sleep posture and sleep breathing physiological information. Information, or a combination of both to generate a warning, perform sleep breathing physiological feedback training and/or sleep posture training. In addition, when set in the second body position, if used during sleep, it can also be implemented to provide a warning based on the obtained sleep physiological information to perform sleep breathing physiological feedback training. Therefore, there are various There is no limit to the possibility of implementation. And the warning unit can be arranged in different positions according to requirements, for example, it can be arranged in the housing, it can also be arranged on another wearable device, such as a smart watch, a smart bracelet, etc., or it can be arranged on an external device, For example, smart phones, therefore, there are various options.

Moreover, depending on the location of the installation, you can choose to use vibration warning and/or sound warning. For example, when it is installed on the ear and/or near the ear, it is suitable to use the sound warning. When it is installed on the trunk, neck, upper limbs (finger, Wrist, arm, etc.), suitable for vibration warning, when set on the head, both vibration and sound warning are suitable, and it can also have two kinds of warnings at the same time, and can be selected according to different positions or user preferences Suitable warning; in addition, the warning unit can also be implemented as a headset driven by other devices (for example, smart phones, smart watches, smart bracelets, etc.) to provide sound warnings, so there is no limitation.

Another implementation possibility is that a sleep system includes a housing, at least one wearable structure, for disposing the housing on a first body part and a second body part respectively, and a control unit including at least a microcontroller/ The processor, a first physiological sensor and a second physiological sensor, are electrically connected to the control unit for obtaining different physiological information on the first body part and the second body part respectively, and a posture sensor The detector is electrically connected to the control unit, and is used to obtain information about a user's sleeping posture, a communication module, and a power module when it is set on the first body part.

By using more kinds of physiological sensors, this sleep system also provides more possibilities. For example, in a preferred embodiment, the first body part is implemented as a torso, head, neck, etc., and the first physiological sensor is implemented as a snoring detector, such as an accelerator or a microphone. The second body part is implemented as a finger, wrist, arm, etc., and the second physiological sensor is implemented as a light sensor. In this configuration, it is advantageous that when placed on the first body part, this The system will be able to obtain both snoring related information and sleep posture related information at the same time, so it can know the relationship between snoring and sleeping posture, that is, in addition to determining whether a snoring event occurs, it can further determine whether it is postural snoring, and Provides posture related information for the user's snoring event. In addition, when set on the second body part, the light sensor can be used to obtain blood physiological information, such as blood oxygen concentration, heart rate, breathing behavior, etc., and through analysis of blood Physiological information, you can know whether blood physiological sleep-respiratory events occur during sleep, for example, oxygen loss Harmony events, low oxygen level events, and heart rate changes sleep breathing events, that is, through such a system, the most common snoring events and blood physiological sleep breathing events can be detected by using the same system, which can provide the greatest Ease of use. Here, if the snoring detector is implemented as an accelerometer, the acceleration can also be used as a posture sensor to further simplify the manufacturing process and reduce costs.

In the above-mentioned various embodiments, the provision of various information is achieved through an information providing interface, and the information providing interface can be set on the housing or can be achieved by using an external device. In this case, the system can be used to include Communication module, and transmit information to external devices through wired or wireless means, so there are various possibilities without limitation.

Furthermore, another conception is to obtain sleep physiological information that can determine various sleep breathing events and the relationship between sleep breathing events and sleep posture in the simplest way without changing the setting position.

An implementation possibility is that a sleep system includes a housing and a wearable structure for placing the housing on a user. The sleep system also includes a control unit, including at least a microcontroller/processor, A communication module and a power module. The aspect of obtaining sleep physiological information is achieved through a posture sensor and a physiological sensor that are electrically connected to the control unit, wherein the posture sensor It is used to obtain the sleep posture related information of the user during sleep, and the physiological sensor is used to obtain the snoring related information during sleep. Here, in particular, because the sleep posture related information is obtained by the torso And the neck above the torso is the best position. Therefore, the physiological sensor uses an accelerometer to obtain snoring-related information by detecting the body cavity vibration caused by snoring. Especially when the accelerometer is used to detect snoring, it can be protected from the outside world. Affected by environmental sound, it can detect normally even when it is covered by clothing or quilt, which is a very convenient choice.

Accordingly, through the obtained sleep posture related information and snoring related information, a snoring sleep posture related information can be obtained, which will be very useful information for the user, especially by simply setting a single device on the torso , You can know whether there is snoring, and you can further understand the relationship between the occurrence of snoring and sleeping posture. For example, the distribution and proportion of snoring in different sleeping postures is a simple and effective choice, especially suitable for home Perform testing. Here, in particular, the physiological sensor implemented as an accelerometer can also be used as a posture sensor at the same time to further simplify the manufacturing process and reduce the cost, so there is no limitation.

In addition, when the accelerometer is installed on the torso, in addition to snoring-related information, as mentioned above, other sleep-respiratory physiological information can also be obtained, such as breathing movement and heart rate; in addition, other things such as light sensing can also be added The physiological sensor of the device also obtains sleep physiological information from the surface of the torso, such as sleep breathing events, heart rate, breathing behavior, sleep stage, etc., to make the detection results more accurate by comparing various sleep physiological information.

Furthermore, further, a warning unit can also be added to provide sleep posture training and/or sleep breathing physiological feedback training. For example, the obtained sleep posture related information can be compared with a preset posture range, and a warning behavior can be determined when the preset posture range is met, and a warning can be provided to perform sleep posture training; or the obtained sleep Respiratory physiological information, such as snoring-related information, breathing movements, heart rate, etc., are compared with preset conditions to determine warning behaviors when the preset conditions are met, and provide warnings to perform sleep breathing physiological feedback training; or, It can provide proper sleep posture training and sleep breathing physiological feedback training by observing these two kinds of sleep physiological information during the same sleep period. Therefore, there are various implementation possibilities without limitation.

The warning is provided in that the control unit is constructed to generate a driving signal, and after receiving the driving signal, the warning unit generates at least one warning, and provides the at least one warning to the user to achieve a sleeping posture The purpose of training and/or sleep-respiratory physiological feedback training, wherein the driving signal is implemented to be generated according to various warning behaviors determined above.

Here, it should be noted that, as is well known by those with ordinary knowledge in the art, the operation of the device/system must have basic circuit configurations such as control units, communication modules, and power modules. Since these are all repetitive content, Therefore, in the description of all the following embodiments, it will be omitted without repeating it, and the actual circuit configuration of all devices in this case is not limited thereby.

Another implementation possibility is that a sleep system includes a housing and a wearable structure for setting the housing on a user's body, and obtaining sleep physiological information through a posture sensor and a Physiological sensor to achieve, where the posture sensor is used to obtain the user’s sleep posture related information during sleep, and the physiological sensor is implemented It is a light sensor to obtain blood physiological information during sleep. Here, in particular, since the torso and the neck above the torso are the best positions for the acquisition of sleep posture related information, the light sensor is also The blood physiological information is obtained from the skin surface of the trunk or neck, such as heart rate, and in particular, as mentioned above, the sleep stage related information can be obtained by further analyzing the heart rate, for example, by analyzing the heart rate distribution or Obtained by calculating HRV (heart rate variability), performing Hilbert-Huang transform (HHT) or other conventional analysis methods, and then understanding the distribution of sleep stages, such as deep sleep and light sleep Respectively, the proportion of the total sleep period, etc., can obtain information related to sleep quality. This is very helpful information for users. In particular, sleep posture training uses warnings to cause changes in sleep posture, thereby achieving the effect of reducing sleep apnea/hypopnea. Observe the distribution of sleep stages/sleep quality during training. It will help to adjust the parameter settings that provide warnings and make the training process more comfortable.

In addition, when the posture sensor is implemented as an accelerometer, the accelerometer can also obtain physical activity during sleep, which can be further analyzed together with the heart rate to obtain more accurate sleep stage related information. Furthermore, the blood physiological information can also be used to obtain other sleep physiological information, such as sleep breathing physiological information, sleep breathing events, heart rate variability, and arrhythmia.

In this case, when there is a warning unit, the sleep posture related information can be compared with the preset posture range, and the warning behavior can be determined when the preset posture range is met, and warnings can be provided to perform sleep posture training. In addition, because The blood physiological information can be continuously detected during sleep. In this way, the blood physiological information can be used to confirm the improvement effect of providing warnings, for example, whether the occurrence of sleep breathing events is reduced due to changes in sleep posture, and also Various related information other than blood physiological information can be provided to the user through the information providing interface, such as the number and time of warning execution, the change of sleep posture, the ratio of different sleep postures, the number of occurrences of sleep breathing events, time point, etc. , The user will be able to clearly know whether the sleep posture training performed has an effect and what the effect is. Therefore, the blood physiological information obtained can also be used as a basis to adjust warning behaviors, not only can provide more warnings It is effective and can minimize the interruption to the user's sleep, so it is quite advantageous.

Of course, in order to understand the difference before and after the sleep posture training, it can also be implemented as, At the beginning, the warning unit does not provide warnings, but only obtains the user’s sleeping posture, coupled with blood physiological information, to know the relationship between the occurrence of sleep breathing events and different sleeping postures. In this way, when you start When performing sleep posture training, you can further obtain the effect of providing warning or not, for example, whether the proportion of different sleep postures changes, and whether the occurrence of sleep breathing events is reduced.

Further, the warning behavior can also be implemented to be determined based on sleep posture related information and/or blood physiological information, that is, you can choose to perform sleep posture training, perform sleep breathing physiological feedback training, or perform both together during the same sleep period. Therefore, there are no restrictions, there are various possibilities.

Another implementation may be that a sleep system includes at least one housing and a wearable structure for placing the housing on a user’s forehead, and obtaining sleep physiological information through a posture sensor and This is achieved by a light sensor, where the posture sensor is used to obtain information about the sleeping posture of the user during sleep, and the light sensor can obtain blood physiological information from the forehead during sleep, such as , Blood oxygen concentration, heart rate. In addition, the system will also include a warning unit to perform sleep posture training and/or sleep breathing physiological feedback training based on sleep posture related information and/or blood physiological information.

Such a system provides a variety of advantageous implementation options. For example, the warning unit can optionally be implemented to provide warnings based on information related to sleep posture. In this case, blood physiological sleep-respiratory events derived from the blood physiological information, such as oxygen desaturation events, hypoxia Level events, heart rate changes, sleep breathing events, will help users understand the sleep breathing situation during sleep posture training, for example, the distribution of sleep breathing events in different sleep postures, and can provide users with blood physiological sleep breathing event posture correlation Sexual information, such as posture-related information about oxygen desaturation events, can also understand the effects of training execution, for example, the number of sleep-respiratory events during training changes, whether they are reduced due to posture changes, etc.; in addition, the warning The unit can also be implemented to provide warnings based on sleep posture related information and blood physiological information at the same time, so that sleep posture training and sleep breathing physiological feedback training can be provided together during the same sleep period, so that the improvement effect is more comprehensive; in addition; , You can also choose not to provide a warning first, and then through the obtained sleep physiological information, it will be able to determine whether a sleep breathing event has occurred. And the correlation between the occurrence of sleep breathing events and sleep posture, and then, based on the results of the judgment, choose which training to perform.

And, most importantly, for the user, the various functions and options mentioned above can be achieved simply by placing it on the forehead. It can be used for evaluation, and can also be used to improve sleep disordered breathing. It can also be selected according to needs. In particular, the change in blood oxygen concentration is one of the most widely accepted and most relevant physiological parameters for judging sleep breathing events, and the most effective results can be obtained under the simplest configuration.

Further, other physiological sensors can also be set, for example, acceleration or microphone can be set to obtain snoring-related information, as a basis for providing warnings, and snoring-based sleep breathing physiological feedback training can also be more comprehensive To understand the occurrence of sleep-disordered breathing, in particular, the accelerometer can also be used as a posture sensor to further simplify the manufacturing process and reduce costs; EEG electrodes, eye electrodes, and/or EMG electrodes can also be set to obtain EEG signals, ocular signals, and/or EMG signals, and by analyzing EEG signals, ocular signals, and/or EMG signals, we can know the sleep state/stage, sleep cycle, etc. during sleep, and then Providing the distribution of sleep breathing events in each sleep stage, as well as the relationship between sleep posture and sleep stage, will help gain further understanding.

Here, since the position is set on the forehead, the wearing structure can be implemented as a headband and/or an adhesion structure, in particular, it can also be implemented as an eye mask. Generally, the eye mask will cover at least the forehead when worn. Part of it, as long as the housing is placed in a position where the forehead can be touched, the light sensor can obtain blood physiological information, and the use of eye masks during sleep helps to fall asleep, which is a quite advantageous choice; in addition, The position of the forehead also allows more options for the types of warnings, which can be implemented as tactile warnings, audible warnings, and/or visual warnings, without limitation; in addition, additional housings can also be selected, for example, implemented as two or more electrical The connected shell not only helps to reduce the volume of individual shells, but also allows the setting to further conform to the curvature of the forehead, which is also advantageous.

Furthermore, when there is a need to provide information to users, the information can be provided by setting the information providing interface, or by setting the communication module, for example, wireless communication modules such as Bluetooth, BLE, Zigbee, WiFi, RF, etc. Group, or wired communication module such as USB interface, UART interface, It is sent to an external device to be provided by the information providing interface on the external device. Here, the external device can have various possibilities, such as smart phones, smart wearable devices, tablet computers, personal computers, or other receptive There are no restrictions on devices with information and an information providing interface.

Another implementation may be that a sleep system includes a housing and a wearable structure for placing the housing on a user's body, and obtaining sleep physiological information through a posture sensor, a A first physiological sensor and a second physiological sensor are achieved, wherein the posture sensor is used to obtain the sleeping posture of the user during sleep, and the two physiological sensors are used to Obtain two kinds of sleep breathing physiological information, and among them, the first physiological sensor is constructed to obtain a snoring-related information during sleep to obtain snoring events, and the second physiological sensor is constructed to obtain sleep The blood physiological information during the period is used to obtain the blood physiological sleep-respiratory event, and is provided to the user through the information providing interface.

As mentioned earlier, sleep breathing disorder is divided into snoring and sleep apnea/hypopnea. Therefore, if information on these two types of sleep breathing disorder can be provided at the same time, it will be a very convenient choice for users, especially, Snoring is generally regarded as a precursor to the appearance of sleep apnea/hypopnea. Moreover, the occurrence of sleep apnea/hypopnea is often accompanied by the appearance of snoring. For example, but not limited to, one situation is that the airway is gradually blocked and breathing The sound becomes heavier and snoring occurs, and finally sleep apnea/hypopnea occurs. Another situation is that after sleep apnea occurs, snoring will occur when breathing is resumed. Therefore, these two physiological phenomena can be used in most cases. Circumstances are used as the basis for confirming whether sleep apnea/hypopnea really occurs. Besides, when blood physiological information is used as the basis for judging blood physiological sleep-respiratory events, such as oxygen desaturation, heart rate changes, low oxygen levels, etc., the body’s Actions are likely to cause artifacts in physiological signals, leading to misjudgments. Therefore, the correlation between the two kinds of physiological information can effectively reduce the occurrence of misjudgments and improve accuracy.

Accordingly, in this implementation possibility, by simultaneously observing blood physiological information and snoring-related information, when a predetermined combination of conditions is met, such as the timing relationship and sequence of the two, it is determined whether a blood physiological sleep breathing event occurs. To achieve the purpose of providing more accurate information.

Under this premise, the most important thing to consider when choosing a setting location is the sleeping position Therefore, the position of the housing is preferably head, torso, etc. When it is installed on the torso, snoring related information can be obtained by, for example, accelerometers to obtain body cavity resonance caused by snoring, and microphones to obtain snoring sound , And the detection of sleep apnea can use, for example, a light sensor to obtain blood physiological information including heart rate; in addition, when set on the head, an accelerator and/or microphone can also be used to obtain snoring related information, and The detection of sleep apnea/hypopnea can obtain blood physiological information including blood oxygen concentration and heart rate by a light sensor. Then, based on the blood physiological information, blood physiological sleep-respiratory events can be derived, for example, Oxygen desaturation events, low oxygen level events, heart rate changes, sleep breathing events.

Here, when set on the head, the wearing structure can be implemented as a headband and/or adhesion structure, in particular, can also be implemented as an eye mask, especially during sleep, the use of the eye mask will help fall asleep Moreover, the forehead is originally suitable for setting up a posture sensor, and the area of the forehead that the eye mask will contact is just suitable for placing physiological sensors, such as light sensors, EEG electrodes, eye electrodes, and EMG electrodes. Obtain various physiological information to understand sleep physiology.

Then, it is compared with the sleep posture related information obtained by the posture sensor to obtain the snoring that occurs when the preset sleep posture range is met and when the preset sleep posture range is exceeded. The distribution of events and blood physiological sleep breathing events, for example, posture-related snoring index, posture-related snoring times, posture-related snoring duration, posture-related sleep apnea index, posture-related blood physiology sleep breathing events, and posture-related blood physiology The information about the duration of sleep breathing events is very helpful to users. Not only can you know that your sleep breathing disorder is snoring and/or sleep apnea, but you can also better understand the occurrence of sleep breathing disorder and sleep. The relationship between postures is both powerful and easy to use.

Moreover, when it is installed on the head, if further EEG electrodes, EOG electrodes, and/or EMG electrodes are provided to obtain EEG signals, OG signals, and/or EMG signals, and by analyzing EEG signals , Ocular signals, and/or myoelectric signals can know the sleep state/stage, sleep cycle, etc. during sleep, and then provide the distribution of sleep breathing events in each sleep stage, and the relationship between sleep posture and sleep stage. Will be more helpful to gain further understanding.

Furthermore, a warning unit can also be added to provide sleep posture training And/or sleep breathing physiological feedback training. For example, the obtained sleep posture related information can be compared with a preset posture range, and a warning action can be determined when the preset posture range is met, and a warning can be provided to perform sleep posture training; or the obtained snoring The relevant information and/or blood physiological information is compared with preset conditions to determine warning behaviors when the preset conditions are met, and provide warnings to perform sleep breathing physiological feedback training; or, during the same sleep period, through Observe these two kinds of sleep physiological information to provide appropriate sleep posture training and/or sleep breathing physiological feedback training. Therefore, there are various implementation possibilities without limitation. Moreover, the warning unit can be arranged in different positions according to requirements. For example, it can be arranged in the housing, on another wearable device, or on an external device. Therefore, there are various options.

Another implementation possibility is that a sleep system includes a housing, at least one wearable structure, a control unit, at least a microcontroller/microprocessor, at least one respiratory and flu detector, electrically connected to the control unit, and a physiological The sensor is electrically connected to the control unit, a communication module is electrically connected to the control unit, and a power module, wherein, through the at least one wearable structure, the housing and the at least one breathing flu detector Will be set between the user’s mouth and nose, that is, in humans, to obtain sleep breathing airflow changes during the user’s sleep. In addition, the physiological sensor is used to obtain another sleep physiological information. Therefore, the at least one respiratory flue detector can be implemented as a thermistor, thermocouple, or airflow tube, without limitation. Among them, the respiratory airflow tube detects the flow change of the respiratory airflow, and the thermistor and thermocouple detect It is the temperature change caused by the breathing airflow, and two detection points (near the two nostrils) or three detection points (near the two nostrils and near the mouth) can be selected.

In this configuration, in particular, as is well known, measuring respiratory airflow is the most direct way to understand the breathing situation, and then sleep apnea events and/or sleep apnea events can be derived. Therefore, the housing size is small enough In the case of, for example, when the size is less than 20x20x20mm, as shown in Figure 8, it can be set between the nose and mouth through a suitable wearing structure, and the breath flu detector can be placed between the nose and mouth. Among them, There are many options for the wearing structure. For example, the shell can be fixed between the nose and mouth by means of adhesive, and the area between the nose and the mouth or on both sides of the mouth can be selected, or it can be sandwiched between the septum and the nose. / Or the fixed structure of the two sides of the nose is provided with a housing and a respiratory air flu detector, or it is fixed by clamping and pasting at the same time, so there is no restriction. It can be any way to achieve fixation; and preferably, in addition to the commonly used plastic shell materials, the shell can also be made of soft or elastic materials to provide the best comfort.

The physiological sensor can be used to obtain more sleep physiological information during sleep. For example, it can be implemented as an accelerometer to obtain sleep posture and snoring related information, and it can also be implemented as a light sensor to obtain blood oxygen concentration. , Heart rate, etc., can also be implemented as a microphone to obtain snoring related information, and no matter what kind of sleep physiological information is obtained, after matching with the changes of respiratory airflow, it is a meaningful combination for further understanding of sleep disordered breathing.

The at least one wearing structure can be implemented as two wearing structures, which are respectively removably combined with the shell to install the shell on other body parts, such as forehead, ears, torso, fingers, wrists, arms, etc. At time, the physiological sensor can be constructed to obtain various physiological information such as blood oxygen concentration changes, heart rate, snoring-related information, sleep posture, sleep physical activity, daily physical activity, etc., as another use option, here, in particular Yes, since the sampling position of the respiratory air detector is limited to between the mouth and nose, when the housing is separated from the wearing structure provided there, it can be implemented to be separated from the respiratory air detector, and thus be separated from another When the wearing structure is combined and arranged on other body parts, a simpler structure can be provided.

In addition, for the sake of sanitation and/or use by multiple people, even if the position is not changed for other tests, the breathing flu detector and the housing can be implemented in a removable form. In other words, it is also advantageous to implement it in the form of a replaceable breathing air flu detector.

The sleep system may further include a wearable device, and another physiological sensor is provided on the wearable device, for example, a light sensor, an accelerometer, a microphone, etc., which are set on the wrist, fingers, torso, head, etc. Position to obtain additional sleep physiological information such as changes in blood oxygen concentration, heart rate, breathing movement, snoring related information, sleep posture, sleep physical activity, etc. In this way, through the comparison of various sleep physiological information, more diversified For example, in the case that the respiratory air flu detector can obtain the actual respiratory airflow change, if it is combined with the accelerometer installed on the torso to obtain the breathing action, it can determine the occurrence of sleep apnea events and / Or sleep apnea event belongs to obstructive sleep apnea with fluctuations in the chest and abdomen, or central sleep apnea without fluctuations in the chest and abdomen.

The sleep breathing system can also be equipped with a warning unit to provide warnings based on changes in respiratory airflow and/or sleep physiological information. If the sleep physiological information includes sleep posture, it can be used to perform sleep posture training and/or include changes in respiratory airflow And/or other sleep physiological information can be used to perform sleep breathing physiological feedback training, and the warning unit can be arranged in the housing, or an external device, such as a communication module arranged in the housing There are no restrictions on bracelets, watches, mobile phones, etc. that communicate with each other.

So far, it can be seen that for the sleep system of this case, how to install it on the user is of great importance. In particular, the tactile warning provided by the warning unit, for example, the vibration warning, requires a stable and tight contact between the housing and the skin at the installation location. Vibration can be effectively transmitted to the user through contact. In addition, there are many physiological sensors that obtain physiological information that requires good contact with the skin. For example, the best sampling method for light sensors is to apply pressure to the skin. , Posture sensors, accelerometers, etc. are most effective in detecting sleeping postures, body cavity vibrations caused by snoring, chest and abdomen fluctuations caused by breathing, and body movements during sleep when they are tightly attached to the skin.

One of the setting options is to stick the shell on the skin, for example, through the adhesive structure, as long as the size of the shell is suitable, it can be set; in addition, you can also choose to use elastic clothing as a medium for setting the shell to make the shell The body is attached to the body surface.

The embodiment is to provide a fixing structure to generate a fixing force so that the casing is arranged on a piece of clothing, and at least a part of the piece of clothing can provide an elastic force to exert force on the skin surface when the user wears the clothing. In this way, a compact layered structure including the shell, the clothing and the skin surface is formed, and through the compact layered structure and the elastic force, the shell can be tightly attached to the body surface, whether it is a tactile warning Provide, or set the physiological sensor, can be more effective.

There are different options for the location of the housing. It can be placed on the inside of the clothing and sandwiched between the clothing and the surface of the skin. In addition, it can also be placed on the outside of the clothing and can be placed through the clothing. Closely attached to the body surface. In addition, if the physiological sensor needs to obtain physiological information from the body surface, such as a light sensor, when setting the housing, pay attention to the surface with the physiological sensor facing the skin surface of the torso .

The fixing structure and the way of fixing clothes can be changed according to actual needs. Restrictions, for example, can be implemented as adhered to clothing, for example, the shell is adhered to clothing using an adhesive structure; it can also be implemented as a clamping structure, such as a mechanical clamping structure, a magnetic clamping structure, etc. Various options.

A preferred embodiment of the clamping structure is to have a containing groove that can receive the shell to achieve the combination between the shell and the clamping structure, and then only need to clamp the clamping structure on the clothes. At the same time, the housing can be set up, which is quite convenient. According to different requirements, the accommodating groove can be set on the inside or outside of the clothes. In addition, if a physiological sensor is set on the surface of the housing, the housing is placed and accommodated. When it’s in the groove, you need to take care to expose the physiological sensor, there is no restriction.

When the magnetic clamping structure is adopted, a preferred embodiment is to provide a magnetic material at the end of the housing to achieve the effect of magnetic attraction and fixation with another magnetic material on the other end of the clothing. The magnetic substance can be arranged in the casing, for example, an additional magnetic substance is placed in the casing, or a battery made of metal that can achieve magnetic attraction is directly used as the magnetic substance, or it can be arranged outside the casing, for example, with The housing is arranged in the containing groove together or embedded in the containing groove, both of which can be implemented; in addition, between the containing groove and the other end with the other magnetic substance, there may be further An elastic connecting piece uses the characteristic of being bendable to form a clamping concept.

Here, it should be noted that the elasticity of the clothing can come from the material used to make the clothing, for example, elastic cloth, or it can be an elastic object added to the clothing, for example, an elastic band sewn, and the clothing can be in addition to clothing. In addition to tights, underwear, pants, etc., it can also be placed on other clothing on the torso, such as eye masks, surrounding belts, for example, RIP sensors placed on the torso, so there is no limitation.

So far, it can be seen that in different embodiments of the sleep physiological system in this case, there are different implementation methods according to different usage requirements and differences in hardware configuration. For example, a decentralized form can be selected, or the selection can be based on needs. Change the setting position and so on. Therefore, as shown in Figure 9, as long as by matching different wearing structures, for example, implementing a removable form between the shell and the wearing structure, the requirements for setting on different body parts can be easily achieved. , Quite advantageous.

In the concept of another aspect of this creation, in addition to using the warning unit to alert the body for sleep posture training and/or to achieve sleep breathing physiological feedback, it is aimed at obstructive sleep Symptoms of apnea can also be improved by using mouth closure aids. The mouth closure aid is placed around or near the respiratory tract during sleep to improve the problem of respiratory tract collapse.

The chin strap 901, as shown in FIG. 10A, is a known mouth closure assist element that can improve the symptoms of snoring and obstructive sleep apnea. It wraps around the head through the strap and applies force on the chin to allow use The chin bone is lifted up and the larynx muscles are affected by the action of closing the mouth, making the upper airway easier to maintain. This way, even during sleep when the muscles are relaxed, the mouth can be maintained and closed. The airway maintains a smooth effect and improves the symptoms of snoring and obstructive sleep apnea.

Another known mouth closure aid that can be used to improve airway stenosis and/or collapse during sleep is the mouth positioning fitting 902, as shown in FIG. 10B, which reduces the mouth by positioning the upper and lower lips in a closed state. The part opens during sleep, and its effect is similar to the above-mentioned chin strap. It can affect the muscles of the larynx by maintaining the closure of the mouth, so that the upper airway is easier to maintain. In addition, through this method It also avoids mouth breathing, so it is another simple and effective choice.

However, the improvement of snoring and obstructive sleep apnea/hypopneas due to the setting of mouth closure aids varies from person to person. For example, each person has a different throat structure and sleeping posture, so that the effect of opening the airway is also effective. Therefore, if you can obtain physiological information during use, such as snoring information, blood oxygen concentration, heart rate, changes in respiratory airflow, breathing movements, etc., you can know whether the symptoms of respiratory tract stenosis have improved, for example, oxygen loss Whether the occurrence of saturation respiratory events, low oxygen level respiratory events, heart rate change respiratory events, snoring events, sleep apnea events, and/or sleep apnea events decreases, will be more effective for users Combination method.

Therefore, it can be used with physiological sensors, such as light sensors, accelerometers, respiratory air flu sensors, piezoelectric motion sensors, impedance detection electrodes, RIP sensors, piezoelectric vibration sensors, and / Or microphone, use together. For example, the user can first use the light sensor to detect during sleep, if a blood physiological sleep breathing event is found, for example, oxygen desaturation respiratory event, low oxygen level respiratory event, heart rate change respiratory event, or Using accelerometer, Microphones and/or piezoelectric vibration sensors obtain snoring-related information to understand whether snoring breathing events occur, or other physiological sensors to obtain other sleep-respiratory events. After that, the mouth can be further used during sleep. To maintain the patency of the respiratory tract, and use the physiological sensor again for physiological monitoring during use. In this way, you can clearly understand the improvement effect brought by the use of the oral closure aid, such as sleep Whether the occurrence of respiratory events is reduced is quite convenient. Furthermore, in addition to knowing the effect achieved by the use, it can also be used as a basis for adjusting the setting of the mouth closure aid, such as the tightness of the chin strap and setting The angle, etc., or the viscosity, coverage, etc. of the mouth positioning fittings, help to further improve the use effect.

In this way, the user can know the improvement effect obtained by using the mouth closure aid, which is very convenient. And because there are various physiological sensors available as above, and there are many options for setting positions, for example, they can be set between fingers, wrists, torso, forehead, ears, nose and mouth, etc., so just by matching various wearing structures For example, finger-wearing structure, wrist-wearing structure, head-wearing structure, belt body, patch, etc., or directly set on the mouth closure aid, can be easily achieved, which is extremely advantageous.

Further, a posture sensor can be combined to obtain sleep posture related information. In this case, by comparing the obtained sleep breathing physiological information and sleep posture related information, it will be known whether It is postural sleep breathing disorder, which is more helpful for understanding the type of sleep breathing disorder.

Furthermore, it can also be equipped with a warning unit to warn the user when a sleep breathing event occurs, and perform sleep breathing physiological feedback training. In this way, the upper mouth closure aid can help maintain the airway unblocked. Both The effect is added and has more advantages; furthermore, when both a physiological sensor and a posture sensor are provided, the warning unit can also be implemented to perform sleep posture training and/or sleep breathing physiological feedback training during sleep. Therefore, there are various possibilities, no limit.

On the other hand, the mouth closure aid can also perform sleep posture training together with the posture sensor and the warning unit. For example, in a preferred embodiment, a sleep physiology device can be used, which includes a control unit, including at least a microcontroller/microprocessor, a posture sensor, and is electrically connected to the control unit for Obtain the sleep posture related information of a user during a sleep period, a warning unit, electrically connected to the control unit, for generating at least one warning for the user during the sleep period, a communication module, and a power module, And a wearable structure, which is set on the user through the wearable structure for sleep posture training. In this case, with the help of the mouth closure aid, the upper airway becomes more unobstructed and sleep The effect of posture training is more significant, and through the information providing interface, the user will be able to understand the impact of using the mouth closure aid on the sleeping posture and warning behavior; in another preferred embodiment, it can also be combined Physiological sensors, such as light sensors, respiratory and flu sensors, accelerometers, piezoelectric motion sensors, impedance detection electrodes, RIP sensors, piezoelectric vibration sensors, microphones, etc., to get sleep Physiological information of sleep breathing during the period is obtained, and the sleep breathing event is obtained, and then provided to the user through the information providing interface, so that the effect of using the mouth closure aid to improve sleep disordered breathing can be learned. Therefore, there are various possible combinations without limitation.

The implementation of the above sleep posture training and/or sleep breathing physiological feedback training is that the sleep posture related information is compared with a preset posture range, and when the preset posture range is met, a warning behavior is determined, and a warning is provided to perform the sleep posture training In addition, sleep breathing physiological information, such as snoring-related information, blood oxygen concentration, breathing action, heart rate, etc., is compared with preset conditions to determine warning behaviors when the preset conditions are met, and provide warnings to perform sleep Respiratory physiological feedback training.
