Description

Technical Field

[0001] The present invention relates to the technical field of intelligent mattresses, and in particular to an anti-snoring mattress and a method for guiding adjustment of sleeping posture. Background Art

[0002] Sleep and respiratory health issues have always attracted much attention. According to the data from China Research and Development's "2020-2025 China Sleep Monitoring Industry Status and Development Prospects Report", there are nearly 50 million sleep apnea syndrome patients in China and no less than 150 million snoring people. Studies have shown that long-term snoring has a two-way relationship with a variety of chronic diseases, which can easily lead to diabetes, respiratory diseases, hypertension, sleepiness and fatigue. The vast majority of snoring patients are obstructive snoring, that is, the decrease in nerve excitability and muscle relaxation after the human body enters the sleep state leads to narrowing or blockage of multiple parts of the upper respiratory tract, which in turn causes snoring. The parts that may cause snoring include all upper respiratory tract mucosal structures that lack cartilage support, including the soft palate, uvula, palatine arch, lateral pharyngeal wall and the upper airway part close to the vocal cord plane, but the causes of snoring are mostly the combined results of multiple parts of the respiratory tract at the same time, so it is difficult to cure snoring clinically, especially some surgical treatments are only suitable for local correction.

[0003] The existing methods for stopping snoring mainly include: awakening, local correction and sleeping position adjustment. The awakening method implements electrical stimulation, vibration stimulation or hot and cold stimulation on local parts of the body, wakes up the sleeper, changes the muscle relaxation state of the sleeper, and stops the sleeper from snoring. The awakening method will seriously damage the sleep structure, which is not recognized clinically and is not good for long-term sleep health. The local correction method changes the narrow condition of a single part in the middle of the respiratory airway, such as setting nasal congestion, tooth plugs, chin support, etc., and the correction of a single part cannot effectively stop most snoring situations. At the same time, this type of product is extremely uncomfortable to wear, and it is difficult for the sleeper to fall asleep. In severe cases, it can affect the sleep quality, so doctors do not recommend it. The sleeping position adjustment method can effectively change the sleeping state of the sleeper by changing the sleeping position of the sleeper from supine to side-lying.

[0004] Common products that adjust sleeping posture to stop snoring include side-sleeping anti-snoring pillows, mechanical turning beds or mattresses, and side-sleeping anti-snoring belts. Side-sleeping anti-snoring pillows mechanically change the position and direction of the head, which can only achieve side-turning of the head, and cannot achieve overall unobstructed airway. Side-turning of the head can also lead to poor sleeping posture and cause neck injuries. Side-sleeping anti-snoring belts stimulate the acupuncture points on the waist to produce a pressure and numbness sensation in the human body, so that the body can turn over and lie on the side autonomously during sleep. However, the sleeper needs to wear a waist restraint device all night, which affects the sleeping experience. The mechanical turning mattress sets a power device on the bed or mattress, and mechanically turns the sleeper to turn over and lie on the side. Mechanical turning over can easily cause the sleeper to wake up, affecting the sleep quality of the sleeper. Moreover, when the sleeper moves the sleeping position, the mechanical turning mattress cannot further prompt the sleeper to turn over, making it difficult to achieve the effect of turning over. Summary of the invention

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0054] Common products that adjust sleeping posture to stop snoring include side-sleeping anti-snoring pillows, mechanical turning beds or mattresses, and side-sleeping anti-snoring belts. Side-sleeping anti-snoring pillows mechanically change the position and direction of the head, which can only achieve side-turning of the head, and cannot achieve overall unobstructed airway. Side-turning of the head can also lead to poor sleeping posture and cause neck injuries. Side-sleeping anti-snoring belts stimulate the acupuncture points on the waist to produce a pressure and numbness sensation in the human body, so that the body can turn over and lie on the side autonomously during sleep. However, the sleeper needs to wear a waist restraint device all night, which affects the sleeping experience. The mechanical turning mattress sets a power device on the bed or mattress, and mechanically turns the sleeper to turn over and lie on the side. Mechanical turning over can easily cause the sleeper to wake up, affecting the sleep quality of the sleeper. Moreover, when the sleeper moves the sleeping position, the mechanical turning mattress cannot further prompt the sleeper to turn over, making it difficult to achieve the effect of turning over.

[0055] In the prior art, the sleeper is mainly prompted to turn over by mechanically pushing up to stimulate the skin or by using a large air bag to bulge and change the inclination of the mattress surface. These methods are very stimulating to the sleeper and can easily wake up the subject inappropriately, which has a great impact on sleep.

[0056] The embodiment of the present invention provides a snoring prevention mattress for guiding the adjustment of sleeping posture. Figures 1 to 10 , including a mattress body 1, a skin contact pressure device 2, a body position sensor 3, a sound pickup device and a control device 4.

[0057] The thickness of the mattress body 1 is about 3-5 cm. After being laid on the bed body, it does not change the sleeping style at home, and there is no need to replace the existing bed and mattress in the family.

[0058] The mattress body 1 is provided with a guide area 10, and the width of the guide area 10 is consistent with the width of the mattress body 1, that is, the guide area 10 covers the entire width range of the mattress body 1. No matter how the sleeper adjusts the sleeping position, the body is in contact with the guide area 10.

[0059] When a sleeper lies on the mattress body 1 , the guide area 10 corresponds to the shoulder position or the upper back position of the sleeper.

[0060] In one embodiment, in order to improve the coverage of the guide area 10 , the guide area 10 may cover the shoulders and back of the sleeper. Even if the sleeper adjusts his sleeping position, the shoulders and back will still contact the guide area 10 .

[0061] The skin contact pressure device 2 includes a plurality of skin contact pressure units 21 and pressure sensors 22 arranged below the skin contact pressure units 21 . The skin contact pressure units 21 are arranged in the mattress body 1 and are evenly distributed in the guide area 10 .

[0062] The skin contact and pressure unit 21 can apply pressure to the sleeper's skin, so that the sleeper's skin is in a contact and pressure state. The sleeper turns over autonomously in deep sleep according to the contact and pressure feeling of the skin, and will not wake up during the turning over process. Under the premise of not affecting sleep, the sleeper is guided to turn over and lie on his side autonomously, thereby achieving the effect of stopping snoring.

[0063] The principle of the skin contact and pressure unit 21 guiding the sleeper to adjust the sleeping posture is as follows:

[0064] The human body has the instinct to turn over unconsciously during sleep, and a normal person needs to turn over about 20 times per night. When the local skin of the body is under pressure and accumulates for a certain period of time, the sleeper will unconsciously turn over or adjust the sleeping position. The sleeper's spontaneous turning over is a protective mechanism of the human body after external pressure acts on the skin to avoid poor blood circulation in the local skin. When uncomfortable pressure stimuli act on the pain receptors on the skin, it can stimulate the behavior of turning over during sleep. This turning over process is mainly completed through the autonomic nervous system, so it can be completed both when awake and asleep.

[0065] The skin contact and pressure units 21 are evenly distributed in the guide area 10 . Even if the sleeper adjusts the sleeping position, the skin contact and pressure units 21 that can apply pressure to the sleeper's skin still exist in the guide area 10 .

[0066] It should be noted that the pressure applied by the skin contact and pressure unit 21 to the skin is limited to avoid excessive pressure causing the sleeper to wake up. The pressure application process is slow to avoid excessive stimulation and causing the sleeper to feel uncomfortable.

[0067] A pressure sensor 22 is disposed below the skin contact and pressure unit 21 , and the pressure sensor 22 can sense the pressure transmitted on the skin contact and pressure unit 21 , and determine the contact state between the sleeper's body and the skin contact and pressure unit 21 , wherein the contact state includes the number and position of contacts.

[0068] The body position sensor 3 is arranged in the guide area 10 and is suitable for detecting the position and sleeping posture of the human body, including the supine state and the side-lying state.

[0069] The body position sensors 3 are evenly distributed in the guide area 10 . After the sleeper adjusts the sleeping position, there are still sensing points in the guide area 10 that can detect the sleeper's position and sleeping posture.

[0070] The sound pickup device is used to detect environmental sound information. When the sleeper lies on the mattress, the sound pickup device sends the environmental sound information to the control device 4, and the control device 4 determines whether the sleeper is snoring.

[0071] In one embodiment, after the sound pickup device detects the environmental sound information, it compares the environmental sound information with the snoring sound information model stored in the control device 4 to determine whether the sleeper is snoring.

[0072] The body position sensor 3 , the pressure sensor 22 and the sound pickup device are communicatively connected to the control device 4 , and the control device 4 receives body position information from the body position sensor 3 , ambient sound information from the sound pickup device and contact state information from the pressure sensor 22 .

[0073] When in use, the sleeper lies on the mattress body 1, and the body position sensor 3 can detect the pressure applied by the sleeper at multiple points, and judge the sleeper's sleeping posture and sleeping position according to the distribution of pressure. The sound pickup device detects the ambient sound information, and the control device 4 judges whether the sleeper snores according to the ambient sound information. When the sleeper is in a supine position and snores, it is necessary to guide the sleeper to turn over and lie on his side to reduce or eliminate the sleeper's snoring.

[0074] The control device 4 can switch the skin contact pressure device 2 between a working state and an idle state. In the idle state, the skin contact pressure device 2 does not work. In the working state, at least part of the skin contact pressure units 21 in the skin contact pressure device 2 works.

[0075] From the above, it can be seen that the working process of the anti-snoring mattress for guiding the adjustment of sleeping posture provided by the embodiment of the present invention is as follows:

[0076] The body position sensor 3 identifies the sleeping posture of the sleeper and determines the position of the back area of ​​the sleeper. When the sound pickup device identifies snoring, the pressure sensor 22 can find a suitable skin contact pressure unit 21 under the sleeper's body. The skin contact pressure unit 21 applies pressure to the sleeper's skin, thereby causing the sleeper to turn over by himself during deep sleep. The guide area covers the entire width of the mattress body 1. After adjusting the sleeping position, the sleeper can still select the skin contact pressure unit 21 at a suitable position to guide the sleeper to turn over and lie on his side by himself, which has a better effect in stopping snoring.

[0077] When the pressure sensor 22 is working, it determines the contact state between the sleeper's body and the skin contact pressure unit 21 according to the received pressure value. The contact state includes which skin contact pressure units 21 are in contact and the distribution of the skin contact pressure units 21 under the body.

[0078] The skin contact and pressure unit 21 on the right side of the lower body is driven, and the sleeper turns over to the left and lies on his side. The skin contact and pressure unit 21 on the left side of the lower body is driven, and the sleeper turns over to the right and lies on his side.

[0079] In one embodiment, when formulating a strategy for the sleeper to adjust the sleeping position, the control device 4 may adjust the skin contact and pressure unit 21 on the left or right side of the sleeper in turn to prevent the sleeper from lying on one side.

[0080] The contact state between the sleeper's body and the skin contact and pressure unit 21 is determined based on the pressure value detected by the pressure sensor 22. After the sleeper completes the action of turning over and lying on his side, the pressure value detected by the pressure sensor 22 will change. Therefore, during use, the pressure change of the pressure sensor 22 can also be used to detect whether the sleeper actively turns over and lies on his side or has body movement behavior. After the skin contact and pressure action is completed, the pressure sensor 22 and the body position sensor 3 work together to jointly determine the sleeper's sleeping posture adjustment.

[0081] When the sleeper turns over and lies on his side, the pressure on the skin contact pressure unit 21 is released.

[0082] When the sleeper does not turn over and lie on his side, the pressure on the skin contact and pressure unit 21 is released, and the skin contact and pressure unit 21 in other suitable positions is found through the feedback signals of the pressure sensor 22 and the body position sensor 3 to apply pressure to the sleeper again.

[0083] According to one embodiment of the present invention, the skin contact pressure unit 21 is an airbag, which can apply contact pressure to the sleeper's skin after being inflated. After the contact pressure continues for a period of time, the sleeper will unconsciously turn over or adjust the sleeping position, which is different from the mechanical squeezing or mechanical deflection. The airbag's contact pressure process on the skin is gentle and less irritating, which can prevent the sleeper from waking up and make the sleeper turn over and lie on the side on his own during deep sleep, thereby achieving side-lying snoring prevention.

[0084] The control device 4 is provided with a micro air pump and a multi-way combination switch, and the multi-way combination switch is connected to the micro air pump. The multi-way combination switch is connected to each air bag through the air filling pipeline, so as to realize independent control of each air bag. The control device 4 receives the pressure information of the pressure sensor 22, selects the air bag at the appropriate position to apply pressure to the skin, so as to achieve the best effect of guiding and adjusting the sleeping posture, thereby achieving the purpose of stopping snoring when lying on the side.

[0085] In one embodiment, the multi-way combination switch uses a multi-way solenoid valve, which is communicatively connected to the control device 4 and can independently control each airbag.

[0086] According to one embodiment of the present invention, the diameter of the airbag is between 10 cm and 20 cm, and a single airbag can apply contact pressure to the skin without causing sharp stimulation. The diameter of the airbag is between 10 cm and 20 cm, which can ensure comfort during the touch and pressure process.

[0087] In order to effectively stimulate the shoulders and back of the sleeper, the distance between the air bags should not be too large to avoid the lack of suitable air bags at the shoulders or waist.

[0088] In one embodiment, the distance between the airbags is no more than 30 cm. When the sleeper adjusts his / her sleeping posture or sleeping position, at least 1-2 airbags appear at the shoulders or back, thereby forming a tight touch and pressure layout.

[0089] In one embodiment, the airbags are arranged in a single row, and the airbags correspond to the positions of the shoulders or back of the sleeper. By stimulating the skin at the shoulders or back, the sleeper is guided to actively turn over and lie on the side, thereby achieving the effect of stopping snoring when lying on the side.

[0090] In another embodiment, at least two rows of airbags are arranged, and the spacing between the airbags is evenly arranged. The airbags arranged in multiple rows can stimulate the shoulders and back of the sleeper, covering a wider area, and guiding the sleep position to be adjusted better. When the sleeper adjusts the sleeping position, there are at least 2-3 airbags under the shoulders and back, which can ensure the contact and pressure effect of the airbags on the skin, and the left and right directions of guiding the side turn can be selected.

[0091] The pressure applied by the skin contact and pressure unit 21 to the skin will affect the sleeper's experience. When the pressure of the skin contact and pressure unit 21 is too high, it may reduce the sleeper's comfort and wake the sleeper. When the pressure of the skin contact and pressure unit 21 is too low, the contact and pressure effect on the skin is not obvious, making it difficult to guide the sleeper to actively turn over and lie on the side, and the effect of stopping snoring by lying on the side cannot be achieved.

[0092] According to one embodiment of the present invention, the pressure sensor 22 can also detect the pressure applied by the skin contact pressure unit 21 to the sleeper's skin. Through the feedback value of the pressure sensor 22, the control device 4 can timely adjust the pressure of the skin contact pressure unit 21, thereby allowing the sleeper to actively turn over and lie on his side in a comfortable state.

[0093] In one embodiment, a plurality of pressure sensors 22 are disposed below the skin contact and pressure unit 21. The plurality of pressure sensors 22 are distributed in an array below the skin contact and pressure unit 21. The combined force states of the plurality of pressure sensors 22 can better reflect the contact state between the skin contact and pressure unit 21 and the sleeper.

[0094] In one embodiment, the pressure sensors 22 may be arranged in a 2*2, 3*3, 4*4, etc. arrangement.

[0095] The mattress body 1 is laid on the bed body, which does not change the sleeping style at home, nor does it need to replace the existing bed and mattress in the home. The mattress is used to guide the sleeper to actively turn over and lie on the side, avoiding the installation of other equipment on the sleeper, and reducing the sense of restraint. The sleeper can actively turn over and lie on the side in a relaxed and comfortable state, thereby achieving the effect of stopping snoring when lying on the side.

[0096] According to one embodiment of the present invention, the mattress body 1 comprises a flexible fabric layer 11, a touch and pressure layer 12, a sensor layer 13 and a hard bottom layer 14. The flexible fabric layer 11, the touch and pressure layer 12, the sensor layer 13 and the hard bottom layer 14 are stacked sequentially from top to bottom.

[0097] The flexible fabric layer 11 is close to the skin, has a thickness of about 1-2 cm, and is made of flexible fabric, which increases the comfort of the sleeper.

[0098] The skin touch pressure device 2 is arranged on the touch pressure layer 12, the thickness of the touch pressure layer 12 is about 1 cm, and the skin touch pressure units 21 are evenly arranged on the touch pressure layer 12. According to the position of the sleeper, the appropriate skin touch pressure unit 21 is activated to apply pressure to the sleeper's skin, guiding the sleeper to actively turn over and lie on his side.

[0099] When the skin contact and pressure unit 21 is an air bag, an air-filling pipeline is further provided in the contact and pressure layer 12 , and the air-filling pipeline is connected to a micro air pump of the control device 4 .

[0100] The sensor layer 13 is provided with a body position sensor 3, which can detect the sleeping posture and position of the sleeper and send the sleeping posture and position information of the sleeper to the control device 4. At the same time, the pressure sensor 22 is also provided on the sensor layer 13, corresponding to the lower position of the skin contact pressure unit 21.

[0101] The bottom of the hard bottom layer 14 is a bed board or other mattress, and the hard bottom layer 14 is used to support the skin contact and pressure device 2 so that the skin contact and pressure device 2 applies pressure to the skin of the sleeper.

[0102] exist Figures 2 to 3 In the embodiment, the flexible fabric layer 11, the touch and pressure layer 12, the sensor layer 13 and the hard bottom layer 14 are of the same size and are connected in sequence. In actual use, the touch and pressure layer 12 and the sensor layer 13 only need to cover the functional area, and do not need to cover the entire mattress.

[0103] In one embodiment, the touch-pressure layer 12 and the sensor layer 13 only cover the range of the shoulder and the waist.

[0104] In order to prevent moisture from interfering with the circuit, both the touch-pressure layer 12 and the sensor layer 13 need to have a certain waterproof performance.

[0105] According to an embodiment of the present invention, the touch-pressure layer 12 and the sensor layer 13 both include a waterproof layer, which can isolate the interference of external moisture on the circuit, thereby increasing the service life of the mattress.

[0106] When the skin contact and pressure unit 21 is an airbag, the inflation and deflation of the airbag need to be controlled separately, and each airbag is connected to an inflation pipeline. In order to facilitate the connection between the inflation pipeline and the control device 4, the inflation pipeline is centrally arranged at the edge of the mattress.

[0107] According to one embodiment of the present invention, an interface box 5 is provided at the edge of the mattress body 1, and the interface box 5 is connected to each air bag through an inflation pipeline. The function of the interface box 5 is to bring together the ends of all inflation pipelines, facilitating the connection between the inflation pipelines and the control device 4.

[0108] The other side of the interface box 5 is connected to the multi-way combination switch and the micro air pump, which simplifies the layout of the air pipeline and makes the mattress more concise.

[0109] The interface box 5 is located at the edge of the mattress body 1, which can be the two side edges of the mattress body 1, or the head and foot of the mattress body 1. The interface box 5 is located at the edge of the mattress and will not interfere with the user.

[0110] In one embodiment, the sound pickup device is also installed in the interface box 5, which simplifies the structure of the mattress. The sound pickup device is connected to the microcircuit in the interface box 5 to transmit the environmental sound information to the control device 4.

[0111] In another embodiment, the interface box 5 can also be connected to the interface ends of the body position sensor 3 and the pressure sensor 22 to facilitate the connection between the sensors and the control device 4 .

[0112] The body position sensor 3 is arranged in the guide area 10 and is suitable for detecting the position and sleeping posture of the human body, including the supine state and the side-lying state.

[0113] According to one embodiment of the present invention, the body position sensor 3 includes a strip-shaped pressure film sensor, which is arranged along the width direction of the mattress body 1 to cover the entire width range of the mattress body 1 .

[0114] When the sleeper adjusts the sleeping position, the sleeper's body contacts different sensing points on the pressure film sensor. According to the width, position and pressure size of the pressure distribution on the pressure film sensor, the sleeper's sleeping position and sleeping posture can be determined.

[0115] When the sleeper lies on his back, the pressure coverage is wider and the pressure value is smaller, and the sleeper's arm will form a pressure sensor alone. When the sleeper lies on his side, the pressure coverage is narrower and the pressure value is larger. The above characteristics can be used to determine the sleeper's sleeping position.

[0116] When the number of the pressure film sensors is one, the pressure film sensor is arranged corresponding to the upper back of the sleeper, and the sleeping posture and position of the sleeper are determined according to the pressure distribution of the one pressure film sensor.

[0117] When the number of the pressure film sensors is 2, the pressure film sensors are provided corresponding to the upper back and the lower back of the sleeper.

[0118] When the number of the pressure film sensors is 3, the pressure film sensors are provided corresponding to the head, upper back and lower back of the sleeper.

[0119] The sleeping posture and position of the sleeper are judged according to the pressure distribution on different pressure film sensors. The data of multiple pressure film sensors are mutually verified, and the judgment result is more accurate. At the same time, when multiple pressure film sensors work together, it can be judged whether the sleeper is tilted when sleeping. When the sleeper is tilted when sleeping, the skin contact pressure unit 21 at a suitable position is selected to apply pressure to the sleeper, so that the sleeper adjusts his sleeping posture in the tilted state, thereby achieving the effect of stopping snoring.

[0120] In one embodiment, the spacing between the sensing points on the pressure film sensor does not exceed 2 cm, which is sensitive to human pressure detection and can accurately determine the sleeping posture and body position of the sleeper.

[0121] According to one embodiment of the present invention, the anti-snoring mattress that guides the adjustment of sleeping posture may also include a server and a terminal, which communicate with the control device through a network. The network communication may be wireless communication or wired communication. Wireless communication includes but is not limited to Bluetooth, Wifi, and mobile network communication. For wireless communication methods. The control device needs to further include a wireless communication module to receive information from the outside and output the data generated by the system. The server is connected to the control device through a network, and the control device uploads the sleeper's data to the server, and the server performs comprehensive processing based on the received data. The terminal is connected to the control device through a network, and the control device uploads the sleeper's data, including control instructions, sensor acquisition parameters, etc., to the terminal for display to help the sleeper understand the effect of its use. The terminal can also provide some parameter setting channels, and send some control data to the control device according to the sleeper's input parameters to optimize the algorithm parameters.

[0122] The addition of the wireless communication module enables the system to be interconnected. Through the server's analysis of a sleeper's sleep data, including snoring conditions and anti-snoring effects, the server can provide feedback to the anti-snoring mattress that guides the adjustment of sleeping posture to improve its control algorithm, achieve better anti-snoring effects, and tailor product functions that meet the needs of the sleeper. Alternatively, the server can also perform big data analysis on the sleep data of multiple sleepers to improve the internal algorithm of the anti-snoring mattress that guides the adjustment of sleeping posture.

[0123] The inventor conducted a certain number of sleep experiments, applying continuous pressure stimulation to the back of the sleeper, with a pressure range of 3-8kpa and a duration of 5-60 seconds. About 60% of the touch-pressure experiments triggered spontaneous turning over, and about 15% of the touch-pressure experiments triggered spontaneous moving away. After expanding the surface area of ​​the touch-pressure unit, the moving away behavior can be avoided. In 25% of the touch-pressure experiments, the sleeper had no reaction, and 0 cases of awakening the experimenter. After the sleeper woke up naturally, they said that they had no memory of turning over due to stimulation.

[0124] The above embodiments illustrate the technical solution of guiding the sleeper to adjust from supine to side-lying. In some embodiments, the sleeper may snore while lying on the side. The anti-snoring mattress provided by the embodiments of the present invention can also be configured to adjust the sleeping position of the sleeper while lying on the side, thereby achieving the purpose of adjusting the sleeping position to stop snoring.

[0125] At the same time, the second embodiment of the present invention provides a method for preventing snoring by guiding the user to adjust the sleeping posture. Figure 11 to Figure 12 , including the following steps:

[0126] S1. Acquire first body position information of a sleeper, environmental sound information, and first pressure information of a skin contact and pressure unit.

[0127] S2. Determine whether the sleeper is in a supine position according to the first body position information, and determine whether the sleeper is snoring according to the environmental sound information.

[0128] S3. When the sleeper is in a supine position and snoring, the position of the sleeper is determined according to the first body position information and the first pressure information, and the skin contact and pressure unit at the first position is selected to apply pressure to the sleeper's skin, and at the same time, the process of the skin contact and pressure unit applying pressure to the sleeper's skin is controlled in real time according to the first pressure information.

[0129] It is understandable that after the sleeper lies on the mattress to rest, there is a side-lying or supine posture. When the sleeper lies on his / her back, he / she is prone to snoring. By obtaining the pressure of the sleeper on the body position sensor, the sleeping posture of the sleeper is determined. The breathing sound in the environment is detected by the sound pickup device, and the breathing sound is compared with the snoring sound to determine whether the sleeper is in a snoring state.

[0130] The body position sensor identifies the sleeping posture of the sleeper and determines the position of the back area of ​​the sleeper. When the sound pickup device identifies snoring, the pressure sensor can find the skin contact pressure unit at a suitable position under the sleeper's body, which is the first position. The skin contact pressure unit applies pressure to the sleeper's skin, thereby causing the sleeper to turn over by himself during deep sleep.

[0131] When the skin contact and pressure unit applies pressure to the skin of the sleeper, the pressure change process of the skin contact and pressure unit is effectively controlled according to the pressure information detected by the pressure sensor to ensure that the skin contact and pressure unit does not over-stimulate the sleeper.

[0132] The guide area covers the entire width of the mattress body. After adjusting the sleeping position, the sleeper can still select the skin touch pressure unit at a suitable position to guide the sleeper to turn over and lie on the side by himself, which has a better effect in stopping snoring.

[0133] After completing the above process, it is necessary to detect whether the sleeper is able to turn over and lie on his side. If the effect is not achieved, further measures need to be taken. Therefore, when the sleeper is in a supine position and snoring, the position of the sleeper is determined according to the first body position information and the first pressure information, and the skin contact pressure unit at the first position is selected to apply pressure to the skin of the sleeper, and the pressure change process of the skin contact pressure unit is controlled according to the real-time first pressure information. The following steps are also included:

[0134] S4. Acquire the second body position information of the sleeper and the second pressure information of the skin contact and pressure unit.

[0135] S5. Determine whether the sleeper has adjusted to a side-lying state according to the second body position information and the second pressure information.

[0136] S51. When the sleeper is not adjusted to the side-lying state, the pressure on the skin contact and pressure unit at the first position is released, and the skin contact and pressure unit at the second position is selected to apply pressure to the sleeper's skin according to the second body position information and the second pressure information.

[0137] S52: When the sleeper is adjusted to a side-lying state, the pressure on the skin contact pressure unit at the first position is released.

[0138] According to the data of multiple tests, after the pressure applied by the skin contact pressure unit to the sleeper continues for a period of time, the sleeper will actively turn over and lie on his side. Generally, after the pressure lasts for up to 120 seconds, the sleeper can turn over and lie on his side on his own. If the sleeper does not turn over after the skin contact pressure unit continues for a predetermined time interval, it means that the activated skin contact pressure unit is not the skin contact pressure unit at the appropriate position, and it is necessary to adjust the skin contact pressure unit at other appropriate positions under the sleeper to apply pressure to the sleeper. The other appropriate positions are defined as the second position.

[0139] It should be noted that the above process can be repeated several times until a skin contact and pressure unit at a suitable position is found. After repeated several times, if the sleeper still does not turn over, the skin contact and pressure action is performed again after a period of time.

[0140] In summary, the anti-snoring mattress and method for guiding the adjustment of sleeping posture provided by the embodiment of the present invention comprises a mattress body, a body position sensor, a skin contact pressure device, a sound pickup device and a control device. A guide area covering the entire width of the mattress body is provided on the mattress body, and a body position sensor, a skin contact pressure unit and a pressure sensor located below the skin contact pressure unit are provided in the guide area. The body position sensor is used to detect the sleeping posture and sleeping position of the sleeper, and the pressure sensor is used to detect the contact state between the sleeper and the skin contact pressure unit, and then select the skin contact pressure unit at a suitable position. The sound pickup device obtains environmental sound information for determining whether the sleeper is snoring. The control device receives the information of the sensor and controls the skin contact pressure unit to apply pressure to the skin of the sleeper. The body position sensor identifies the sleeping posture of the sleeper and determines the position of the back area of ​​the sleeper. When the sound pickup device identifies snoring, the pressure sensor can find a suitable skin contact pressure unit under the body of the sleeper. The skin contact pressure unit applies pressure to the skin of the sleeper, so that the sleeper turns over by himself during deep sleep. The guide area covers the entire width of the mattress body. After adjusting the sleeping position, the sleeper can still select the skin touch pressure unit at a suitable position to guide the sleeper to turn over and lie on the side by himself, which has a better effect in stopping snoring.

[0141] When the skin contact pressure unit is an airbag, the stimulation process of the airbag on the skin is relatively gentle, and the airbag applies contact pressure to the skin, thereby guiding the sleeper to actively turn over and lie on the side. The airbag can avoid excessive stimulation of the sleeper's skin, prevent the sleeper from waking up, and provide higher comfort.

[0142] When a pressure sensor is provided below the skin contact pressure unit, the pressure of the skin contact pressure unit can be monitored to keep the pressure contacting the skin in a gentle and effective range to avoid excessive stimulation of the sleeper's skin. The pressure sensor enables the control device to select the skin contact pressure unit at a suitable position below the sleeper's body. Even if the sleeper adjusts the sleeping position, the skin contact pressure unit at a suitable position can still be selected.

[0143] When the mattress body includes a flexible fabric layer, a touch-pressure layer, a sensor layer, and a hard bottom layer stacked in sequence, the thickness of the mattress body is reduced, which does not affect the structure of the original bed and the mattress, and is more convenient to use. In the schematic diagram of the embodiment of the present invention, the length of the mattress body is approximately equal to the length of the entire bed. In an actual solution, the length of the mattress may only include the functional areas: the length of the airbag layer and the sensor layer, and may not cover the entire bed, for example, only the back area of ​​the sleeper may be covered.

[0144] When the interface box is arranged on the mattress body, the interface box gathers the interface ends of the inflation pipeline, thus simplifying the layout of the inflation pipeline in the mattress body and after it extends out of the mattress body.

[0145] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
