Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to an intervention device, method and system for sleep apnea syndrome. Background Technology

[0002] Sleep apnea syndrome is a common sleep disorder characterized by recurrent pauses in breathing or reduced airflow during sleep.

[0003] The upper respiratory tract is a functional lumen composed of multiple deformable tissues, including the soft palate, the base of the tongue, and the lateral walls of the pharynx. During wakefulness, the dilator muscles of the pharynx maintain airway patency through tonic contraction. However, during sleep, especially REM sleep, the excitability of the nerves controlling these muscles significantly decreases, leading to increased muscle relaxation. When patients have anatomical abnormalities such as mandibular retrusion, enlarged tongue, or tonsil hyperplasia, supine sleeping causes the base of the tongue to fall backward due to gravity, and the soft palate and lateral pharyngeal wall fat tissue to compress towards the midline. This further reduces the already narrow pharyngeal cavity cross-sectional area, creating a local negative pressure effect. At this time, the airway pressure gradient generated during inspiration exceeds the maximum compensatory capacity of the dilator muscles, causing airway wall collapse and complete obstruction of airflow, resulting in apnea.

[0004] Due to airway obstruction, the patient's breathing stops, typically lasting from several seconds to several minutes. During this process, blood oxygen levels may drop sharply, triggering an emergency response in the body. The brain sends signals due to lack of oxygen, causing the patient to suddenly awaken in order to resume normal breathing. This situation is often accompanied by loud snoring or a feeling of suffocation. The patient may wake up frequently during the night but does not have a complete memory of their awakenings, resulting in significantly reduced sleep quality.

[0005] Sleep apnea not only affects an individual's nighttime rest but can also trigger a range of health problems. Long-term oxygen deficiency and sleep disturbances may increase the risk of chronic diseases such as hypertension, heart disease, and diabetes, while also causing symptoms such as daytime sleepiness, poor concentration, and mood instability, thus having a profound impact on the patient's quality of life.

[0006] In conclusion, how to provide an intervention device for sleep apnea syndrome is a technical problem that urgently needs to be solved. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sleep apnea syndrome intervention device, method and system. By monitoring the user's breathing status, when an abnormal breathing is detected, the device automatically triggers a jaw elevation operation to restore airway patency, thereby achieving timely intervention.

[0008] This invention provides a sleep apnea syndrome intervention device, comprising: The mandibular support structure can contact the user's mandible and provide support for the user's mandible; The first adjustment structure is set on the mandibular support structure and can change the relative distance between the mandible and the mandibular support structure; The breathing detection structure is used to collect the user's breathing data and send the breathing data to the control center; The control center is used to determine the user's breathing status based on breathing data, and based on the determination result, to trigger the first adjustment structure to raise or lower the mandible relative to the mandibular support structure.

[0009] Furthermore, the first adjustment structure includes airbag assemblies disposed on both sides of the mandibular support structure, the airbag assembly including inflatable airbags; by inflating or deflating the airbags, the relative distance between the mandible and the mandibular support structure is increased or decreased accordingly.

[0010] Furthermore, the first adjustment structure also includes a rolling assembly located above the first adjustment structure. The rolling assembly is rotatably connected to the mandibular support structure via a connector. The rolling assembly can move above the first adjustment structure, thereby intervening between the user's mandible and the first adjustment structure. And / or, a soft bag is provided above the first adjustment structure, and an air outlet is provided on the upper surface of the soft bag; the soft bag is connected to an air pump through an inflation pipe, and the gas generated by the air pump enters the soft bag through the inflation pipe and is ejected through the air outlet.

[0011] Furthermore, the respiratory detection structure includes a collection plate, which is movably and rotatably connected to the jaw support structure via a second adjustment structure; The acquisition board is equipped with an airflow sensor and a sensing module; the sensing module is used to detect the distance data between the acquisition board and the user's mouth and nose, and send it to the aforementioned control center; The control center is used to compare distance data with a preset threshold, and based on the comparison result, controls the second adjustment structure to adjust the distance between the acquisition plate and the user's mouth and nose.

[0012] Furthermore, the breathing detection structure includes a nasal breathing acquisition component located near the user's nose to collect breathing data of the user's nasal breathing; The nasal breathing acquisition component is movably connected to the mouth breathing acquisition component, which can be moved to the vicinity of the user's mouth to collect the user's mouth breathing data.

[0013] Furthermore, a limiting part is provided below the mandibular support structure. The limiting part has a first position and a second position. In the first position, the limiting part is housed within the mandibular support structure. In the second position, the limiting part extends outside the mandibular support structure, contacts the user's shoulder, and limits the mandibular support structure to the user's shoulder.

[0014] This invention provides an intervention method implemented using the sleep apnea syndrome intervention device as described in any one of the above-mentioned methods, comprising the following steps: S1 supports the user's jaw through a jaw support structure; S2 collects the user's breathing data through a breathing detection structure, and the control center determines whether the user's breathing status is normal based on the breathing data. When S3 determines that the user has an abnormal breathing state, the control center triggers the first adjustment structure to raise the mandible relative to the mandibular support structure.

[0015] Furthermore, S2's determination of whether the user's breathing is normal also includes determining the user's sleeping posture; Based on preset scoring criteria, a first score corresponding to breathing data and a second score corresponding to sleep posture are obtained respectively; The first and second scores are weighted to obtain a comprehensive score; the user's breathing status is obtained based on a preset mapping relationship between the comprehensive score and breathing status.

[0016] Furthermore, S2 also includes driving the rolling assembly to move above the first adjustment structure, intervening between the user's chin and the first adjustment structure; and / or, S2 also includes the function of inflating the soft bag and then spraying air into the user's chin through the air outlet.

[0017] The present invention provides a system employing the intervention method as described in any one of the above-described methods, the system comprising a sleep apnea syndrome intervention device as described in any one of the above-described methods.

[0018] By adopting the above technical solution, this invention, as an example, has the following advantages and positive effects compared with the prior art: The chin support structure conforms to the user's chin and provides upward support. The extension can be quickly connected and disconnected from the main body of the chin support structure, making it easy for users to wear and providing high wearing comfort, thus avoiding any impact on the user's sleep quality.

[0019] The system collects users' breathing data in real time and analyzes the data with the control center to accurately determine the user's breathing status. Through the coordinated operation of the sensing module and the second adjustment structure, it ensures that the breathing detection structure is always located near the user's mouth and nose, improving the accuracy and stability of breathing data acquisition.

[0020] When an abnormal breathing pattern is detected, the control center automatically triggers the first adjustment mechanism to elevate the jaw to restore airway patency. Once breathing returns to normal, the jaw height is gradually lowered, achieving precise intervention. The friction massage from the rolling components and the airflow massage from the soft bag promote blood circulation in the jaw area, relieve muscle tension, and further enhance the user experience.

[0021] Compared to surgical treatment or continuous positive airway pressure (CPAP) devices, this invention provides a non-invasive and easy-to-use intervention solution, reducing the psychological and economic burden on users. The device has a simple overall structure, is convenient to use, and is suitable for daily use. Through real-time monitoring and dynamic adjustment, it can quickly intervene when sleep apnea occurs. It reduces frequent awakenings caused by hypoxia, helps users achieve more continuous deep sleep, improves nighttime sleep quality, and effectively reduces the risk of chronic diseases caused by sleep apnea, demonstrating broad application prospects and market value.

[0033] The technical solutions disclosed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be considered isolated; they can be combined with each other to achieve better technical effects. In the accompanying drawings of the following embodiments, the same reference numerals appearing in each drawing represent the same features or components, which can be applied to different embodiments. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the conditions under which the invention can be implemented. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should fall within the scope of the technical content disclosed in the invention. The scope of the preferred embodiments of the present invention includes other implementations, wherein functions may be performed not in the order stated or discussed, including substantially simultaneously or in reverse order, depending on the functions involved. This should be understood by those skilled in the art to which the embodiments of the present invention pertain.

[0035] Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] This invention provides a sleep apnea syndrome intervention device 100, such as... Figure 2As shown, the mandibular support structure 200 can conform to the user's mandible and support the user's mandible.

[0037] The chin support structure 200 can be connected to the user's neck by either being fitted onto the user's neck or clamped to both sides of the user's neck.

[0038] As a typical implementation, the mandibular support structure 200 is an elastic U-shaped structure. The U-shaped structure is fixed behind the user's neck, that is, the opening area of ​​the U-shaped structure faces the user's facial area, while the curved area is close to the back of the user's neck.

[0039] The elasticity allows the size of the U-shaped opening to vary flexibly within a certain range, enabling the U-shaped opening to adapt to the user's neck, contact both sides of the user's neck, and be fixed to the user's neck by elastic clamping force.

[0040] When it is fixed to the user's neck, its upper U-shaped edge contacts the user's jawline, providing upward support and thus supporting the user's jaw.

[0041] Optionally, a soft layer (not shown in the figure) may be provided on the U-shaped edge to improve comfort. The soft layer may be made of silicone, rubber, sponge, etc.

[0042] Optionally, the chin support structure has a certain width, and its lower end can contact the user's shoulder area, which is equivalent to using the user's shoulder area as a base. Combined with the elastic clamping force above, the chin support structure is firmly fixed to the user's neck and shoulders, making it difficult for it to shift or fall off.

[0043] Optionally, such as Figure 3 As shown, it also includes an extension 210, one end of which is hinged to one side of the open end of the U-shaped structure, and the other end is detachably connected to one side of the open end of the U-shaped structure. When one end of the extension 210 is connected to one side of the open end of the U-shaped structure, the U-shaped structure forms a wrapping tendency around the user's neck, equivalent to being fitted around the user's neck. In this configuration, the U-shaped structure does not necessarily need to be elastic, because it does not need to be fixed to the user's neck by elastic clamping force, so a non-elastic material can also be selected.

[0044] Specifically, for example, one side of the open end of the U-shaped structure is pivotally connected to an extension 210 via a movable hinge, and the other side is provided with a dovetail groove slide rail. The end of the extension 210 integrates a columnar buckle.

[0045] Of course, the chin support structure 200 is not limited to the U-shape mentioned above. Other shapes that can form a wraparound shape around the neck, such as a C-shape, a ring-shaped O-shape, a △-shape, or a frame shape, are also acceptable.

[0046] In the first position, the extension 210 is not connected to the slide rail, and the extension 210 can rotate freely around the hinge connection. When the extension 210 rotates to the second position around the hinge axis, its end latch forms a self-locking insertion with the slide rail, so that the extension 210 and the U-shaped main body close loop form a neck restraint ring.

[0047] After the buckle is released, the extension 210 can be rotated and unfolded to the storage position to enlarge the wearing opening.

[0048] Of course, other detachable connection methods, including but not limited to threaded connections, magnetic connections, and friction connections, are also acceptable.

[0049] One end of the extension 210 and the other end of the U-shaped structure are detachably connected to the U-shaped structure.

[0050] like Figure 2-3 As shown, preferably, the first adjustment structure 300 is disposed on the mandibular support structure 200, which can change the relative distance between the mandible and the mandibular support structure 200.

[0051] The first adjustment structure 300 includes airbag assemblies disposed on both sides of the mandibular support structure 200, the airbag assemblies including inflatable airbags.

[0052] Inflatable airbags 310 are typically inflatable structures made of flexible materials, generally possessing good elasticity and pressure resistance. Their volume and shape can be changed as gas or liquid is inflated and deflated.

[0053] The inflatable airbag 310 is equipped with matching tubing and an air pump. The air pump forces gas or liquid into the airbag 310, increasing the distance between the upper and lower parts of the airbag 310, thus increasing its volume and causing the outer contour of the airbag 310 to expand outward. Figure 4 As shown, when the airbag 310 inflates to a certain extent, the upper edge of the airbag 310, that is, the part that contacts the user's chin, will contact the user's chin and apply an upward pushing force to the user's chin, thereby correspondingly increasing the relative distance between the chin and the chin support structure 200, that is, achieving the result of further raising the user's chin relative to the chin support structure 200. Due to the shape and material properties of the airbag 310, the force applied during inflation can be evenly distributed in the contact area of ​​the chin, avoiding excessive local pressure and improving user comfort.

[0054] Conversely, when the air pump operates in reverse or the deflation valve is opened, the airbag 310 deflates and contracts, expelling gas from within it. This reduces the distance between the upper and lower parts of the airbag 310, consequently decreasing its volume. The reduced distance between the upper edge of the airbag 310 and the mandible results in decreased support for the mandible. Compared to the inflated state, the user's mandible height decreases, and the relative distance between the mandible and the mandibular support structure 200 decreases.

[0055] As the upper end of the airbag 310 contacts the user's chin and applies an upward thrust, the lower end of the airbag connects to the chin support structure 200. At this time, the compressive force on the airbag 310 is also transmitted to the chin support structure 200, which then experiences a downward force. The magnitude of this force is directly proportional to the degree of inflation of the airbag 310; that is, the more the airbag inflates, the greater the downward force applied.

[0056] As a typical implementation, the airbag can be positioned on the mandibular support structure at a location corresponding to the angle of the user's mandible, and slightly behind the angle of the mandible, near the base of the ear.

[0057] Alternatively, the airbag can be positioned on the mandibular support structure at the location corresponding to the angle of the user's mandible and the lower edge of the mandible.

[0058] With these two settings, the airbag will more easily lift the user's head when it inflates, achieving a better airway opening effect.

[0059] Optionally, a mesh structure with a recessed top and a flat middle is provided inside the airbag 310 corresponding to the area that contacts the chin, to increase the support effect of the airbag 310 and the comfort during use.

[0060] In another embodiment, the airbag assembly includes an array of airbags 310, which comprises a plurality of columnar sub-airbags 310, each sub-airbag 310 having a different degree of inflation to better adapt to the user's jaw shape and provide a more comfortable support experience.

[0061] The degree of inflation of the sub-airbag 310, by way of example and not limitation, can be set in the following way: by acquiring image information of the user's jaw through the image acquisition component included in the sensing module 430, and by processing and analyzing the image, setting the inflation parameters of each columnar airbag 310 so that it can fit and adapt to the current jaw shape of the user during inflation.

[0062] Of course, it is not limited to airbag components; other forms that can control the height of the device can also be used.

[0063] For example, the first adjustment structure 300 is a telescopic component embedded in the upper edge of the mandibular support structure 200. The telescopic component is telescopic and includes multiple telescopic layers nested together. When the telescopic component is extended, the overall height increases, protrudes relatively from the upper edge of the mandibular support structure 200, and can contact the user's mandible, and can also lift the user's mandible.

[0064] Other alternative methods include embedding a miniature hydraulic or pneumatic cylinder within the chin support structure 200, with a piston-linkage mechanism inside the cylinder. By driving the piston to rise and fall, it can contact or release the user's chin.

[0065] Alternatively, a mesh deformation layer woven from shape memory alloy, such as nickel-titanium alloy wire, can be laid on the upper surface of the mandibular support structure 200, with independent temperature control units at the mesh nodes.

[0066] When a temperature control unit in a certain area is powered on and heated, the SMA filaments of the corresponding grid shrink and deform, causing the surface layer to bulge locally and form support protrusions; multi-area coordinated temperature control can generate a continuous curved surface that dynamically matches the contours of the user's jaw and provides precise lifting force.

[0067] The above are only examples of some implementation methods, and no restrictions are placed on other possible implementation structures for achieving height adjustment.

[0068] When the mandibular support structure is held and fixed to the user's neck by elastic force, the clamping force on the mandibular support structure will increase accordingly when the airbag applies a downward force. This is because the clamping force is proportional to the applied pressure. The downward force of the airbag causes the clamping structure to generate a larger normal force on the contact surface with the neck, thereby increasing the friction. In this way, the clamping force will resist the downward force transmitted by the airbag, preventing the mandibular support structure from sliding or displacing.

[0069] With a certain width, the chin support structure, when its lower end contacts the user's shoulder, creates a relatively large contact area. According to the basic principles of friction, friction is proportional to the contact area, the properties of the contact materials, and the applied vertical force. Due to the contact between the shoulder and the chin support structure, and the presence of friction, this downward resultant force will not cause the chin support structure to slip off the shoulder, but rather maintain it in a relatively stable position. Furthermore, the width of the chin support structure allows for a more even distribution of pressure on the user's shoulder, thus reducing the risk of displacement due to excessive local pressure. The increased width also helps lower the center of gravity of the chin support structure, enhancing its overall stability. A lower center of gravity makes it less prone to overturning or slipping under external forces.

[0070] To further prevent displacement, an adhesive layer can be applied to the contact surface of the chin support structure where it contacts the user's body, thereby strengthening the fixation through adhesion.

[0071] In another embodiment, a limiting part is provided below the mandibular support structure, and the limiting part has a first position and a second position.

[0072] In the first position, the limiting part is housed within the mandibular support structure.

[0073] In the second position, the limiting portion extends beyond the mandibular support structure, contacts the user's shoulder, and limits the mandibular support structure to the user's shoulder.

[0074] In one embodiment, the limiting part includes a limiting airbag that can be locked onto the user's shoulders by contacting both sides of the user's shoulders.

[0075] like Figure 9A As shown, the limiting airbag can be C-shaped, U-shaped, or similar, consisting of two parts, a left side and a right side, and a bridging structure connecting the left and right sides.

[0076] In the first position, the limiting airbag is in an inflated state and is housed within the mandibular support structure.

[0077] In the second position, the limiting airbag is inflated. Gas enters the limiting airbag, causing the limiting airbag to increase in volume and expand beyond the mandibular support structure, contacting both sides of the user's shoulders to form a stable support surface, thereby establishing a connection with the user's shoulders and limiting the position of the mandibular support structure.

[0078] Or, such as Figure 9B As shown, the limiting airbag includes airbag struts located on both sides below the mandibular support structure.

[0079] This is equivalent to the C-type above without the bridging part. Both the left and right parts are separately set, and when inflated, they will contact the user's shoulder, tending to clamp the user's shoulder, thus forming a connection with the user's shoulder.

[0080] Of course, besides using a limiting airbag, other implementation methods can also be used, such as providing a clamping part, which includes a clamp and a folding structure connecting the clamp and the chin support structure. In the first position, the clamping part is folded and stored inside the chin support structure. In the second position, the folding structure is unfolded, pushing the clamping part out of the chin support structure, and the clamp rests on the user's shoulder, thus forming a connection with the user's shoulder.

[0081] Optionally, the clip has a soft layer on the contact surface that contacts the user's shoulder to improve comfort.

[0082] Optionally, such as Figure 5As shown, the first adjustment structure 300 also includes a rolling component 320, which is rotatably connected to the airbag assembly via a connector and can move between the two ends of the upper surface of the airbag assembly.

[0083] As a typical implementation, the connector includes a pivot 220 disposed on the mandibular support structure 200. Taking a U-shaped structure as an example, the connector can be disposed on the upper edge of the U-shaped structure or on the outer side of the U-shaped structure.

[0084] The rotating shaft 220 is connected to the rolling assembly 320 via the rotating arm 321. The length of the rotating arm 321 is set to be able to lift the rolling assembly 320 above the first adjustment structure 300. Taking the airbag 310 as an example, the length of the rotating arm 321 is able to place the rolling assembly 320 above the airbag 310 in the inflated state.

[0085] Optionally, when the first adjustment structure 300 is an airbag assembly, the rotating arm 321 is configured to be length-adjustable, for example, by providing a telescopic part, so that the relative height of the rolling assembly 320 can be flexibly adjusted according to the inflation size of the airbag 310.

[0086] The rotating arm 321 rotates around the rotating shaft 220. As the rotating arm 321 rotates, the rolling assembly 320 will be driven to move along an arc-shaped path, possibly lifting towards the top of the airbag 310 and moving forward or backward. During the movement, the rolling assembly 320 may approach or move away from the contact area between the airbag 310 and the chin.

[0087] The rolling component 320 can apply downward pressure to the airbag 310 and upward pressure to the jaw, entering the space between the airbag 310 and the jaw, replacing part of the airbag 310 to directly contact the user's jaw, and achieving a massage effect through back-and-forth friction on the jaw.

[0088] As a typical implementation, the rolling component 320 can be an airbag 310 or a soft material. For example, the rolling component 320 can have a columnar structure. This design allows the rolling component 320 to move smoothly between the airbag 310 and the jaw, reducing the contact area with the jaw, reducing direct pressure, and reducing friction on the jaw. In addition, the soft material provides a certain degree of flexibility when in contact with the jaw, which can further improve the user's comfort.

[0089] Optionally, such as Figure 8 As shown, a soft bag 330 is provided above the first adjustment structure 300, and an air outlet 331 is provided on the upper surface of the soft bag 330.

[0090] The soft bag 330 is connected to an air pump via an inflation tube 450. Gas generated by the air pump enters the soft bag 330 through the inflation tube 450 and is expelled through the air outlet 331. When the soft bag 330 contacts the user's chin area, the gas is sprayed onto the user's chin skin through the air outlet 331. If the air outlet 331 is designed to be relatively small, the gas entering the soft bag 330 will not immediately leave; some gas will remain inside the soft bag 330, causing the soft bag 330 to expand in volume.

[0091] When the soft bag 330 is inflated, its design can achieve multiple functions at the same time: on the one hand, the inflated soft bag 330 provides stable support for the jaw area; on the other hand, it releases controllable airflow through the air outlet 331, which generates a massage effect by using the pulsed physical stimulation of the local skin, thereby effectively promoting blood circulation and relieving tissue congestion.

[0092] Furthermore, the airbag 310 features an intelligent pressure regulation mechanism—by dynamically adjusting the inflation volume, the overall height of the airbag 310 can be controlled. For example, increasing the airflow causes the soft bag 330 to rise relatively, or decreasing the airflow causes the soft bag 330 to fall relatively, simultaneously driving the mandible to move up and down; forming a gradient-changing "alternating strong and weak" airflow output mode. Through these settings, the massage therapy effect can be significantly improved.

[0093] Preferably, it also includes a respiratory detection structure 400 for collecting the user's respiratory data.

[0094] As a typical implementation method, such as Figure 6 As shown, the respiratory detection structure 400 includes a data acquisition plate 410, on which an airflow sensor 420 is mounted.

[0095] The respiratory data collected by the airflow sensor 420 includes, but is not limited to, respiratory rate: the number of breaths per minute.

[0096] Tidal volume: The amount of air inhaled or exhaled with each breath.

[0097] Breathing patterns: such as evenness, depth, etc.

[0098] Inhalation-to-exhalation ratio: The relative duration of inhalation and exhalation.

[0099] To ensure accurate detection results, the airflow sensor 420 needs to be placed close to the user's nose or mouth. A sensing module 430 is mounted on the acquisition board 410.

[0100] The sensing module 430 is used to detect the distance data between the acquisition board 410 and the user's mouth and nose. The sensing module 430 can be at least one of an image sensor, an infrared sensor, or a capacitive sensor.

[0101] Taking an image sensor as an example, the image sensor includes miniature cameras built into both sides of the acquisition board 410 to continuously capture facial images. The two cameras simultaneously capture stereoscopic images of the mouth and nose area. The system automatically constructs a three-dimensional coordinate model by identifying the positional differences of feature points such as the edges of the nostrils and the contours of the lips in the two images.

[0102] Based on the horizontal offset of the feature points in the two images, combined with the preset camera spacing parameters, the real-time distance between the acquisition board 410 and the face is calculated using the triangulation formula.

[0103] Taking an infrared sensor as an example, the infrared emitter emits a modulated infrared beam at a specific frequency. This invisible light is diffusely reflected when it encounters the user's facial skin, and some of the light returns to the receiver on the surface of the acquisition board 410. When the user breathes, causing a change in the distance between their mouth / nose and the acquisition board 410, the propagation path length of the reflected light changes, resulting in a measurable shift in the phase of the received signal. By calculating the linear relationship between this phase difference and distance, distance changes can be tracked in real time.

[0104] Taking a capacitive sensor as an example, an electrode array is set on the surface of the acquisition board 410. When a user's mouth and nose approach, the conductivity of biological tissue will disturb the original electric field distribution. This disturbance will change the coupling capacitance value between the electrodes. The detection circuit inside the sensor scans the capacitance change. When it detects that the capacitance value is continuously increasing, it indicates that human tissue is approaching. The system will calculate the actual distance according to the preset capacitance-distance curve.

[0105] The sensing module 430 sends the distance data to the aforementioned control center.

[0106] The acquisition plate 410 is moved and rotated to connect to the mandibular support structure 200 via the second adjustment structure 500.

[0107] The second adjustment structure 500 includes a longitudinal movable member 520, a transverse movable member 510, and a steering member 530. The longitudinal movable member 520 is used to drive the acquisition plate 410 to move in the longitudinal direction. The longitudinal movable member 520 can be a telescopic rod, and the displacement in the longitudinal direction is achieved by the extension and retraction of the rod in the longitudinal direction.

[0108] Other alternatives include a slide rail system, where the acquisition plate 410 moves along a longitudinal slide rail on the longitudinal movable part 520 via a slider. Alternatively, a combination of chains and gears can be used, with a motor driving the chain to move the acquisition plate 410 in the longitudinal direction.

[0109] Other similar methods include using spring telescopic structures, screw drives, lead screw guides, etc.

[0110] The lateral movable component 510 is used to drive the acquisition plate 410 to move in the lateral direction. The same implementation method as the longitudinal movable component 520 can be used. For example, a telescopic rod can be used to achieve lateral displacement by extending and retracting the rod in the lateral direction.

[0111] The steering component 530 can be made of components such as universal joints, rotary bearings, hinges, gears, electric rotary motors, etc., to adjust the relative angle between the acquisition board 410 and the preset reference point on the user's face, such as the direction of the facial midline.

[0112] In this embodiment, the longitudinal movable member 520 is connected to the mandibular support structure 200, and the other end is connected to the transverse movable member 510. The acquisition plate 410 is rotatably connected to the transverse movable member 510 through the steering member 530.

[0113] The control center is used to compare distance data with a preset threshold. When the distance data is not greater than the preset threshold, it means that the position of the acquisition board 410 is within a suitable range and no adjustment is needed for the time being. The corresponding control center does not generate any instructions.

[0114] When the distance data is greater than a preset threshold, the control center generates an adjustment command based on the distance data. The command is used to adjust the acquisition plate 410 to the target position through the second adjustment structure 500. At the target position, the relative distance between the acquisition plate 410 and the user's mouth and nose position is within the preset threshold range.

[0115] The breathing detection structure 400 includes at least an airflow sensor 420, which is a device used to detect gas flow. When a user breathes, air enters and exits through the respiratory tract, and the airflow sensor 420 detects changes in airflow. Specifically: When a user inhales, air enters the respiratory tract, causing the sensor to detect an increase in airflow.

[0116] When a user exhales, air is expelled from the respiratory tract, and the sensor detects the reduction in airflow.

[0117] The airflow sensor 420 collects the detected airflow changes as breathing data, converts them into electrical signals, and sends the breathing data to the control center for further processing and analysis.

[0118] In another implementation, such as Figure 7 As shown, the breathing detection structure 400 includes a nasal breathing acquisition component 440, which is placed near the user's nose to collect the user's nasal breathing data.

[0119] For example, the nasal breathing acquisition component 440 is fixed near the user's nose through an insert design.

[0120] For example, it includes a trachea 450 that is inserted into the nostril. Its diameter needs to be designed based on the average size of the human nasal cavity to ensure it is neither too tight nor too loose.

[0121] The trachea 450 is equipped with airflow sensors, and multiple sensors can be installed at different locations to obtain respiratory data by measuring the gas passing through the trachea 450.

[0122] Alternatively, an elastic strap can be used to secure the nasal breathing acquisition component 440 to the user's face near the nose by placing it on the user's head.

[0123] Preferably, the nasal breathing acquisition component 440 is movably connected to the mouth breathing acquisition component 470 via the movable connector 460.

[0124] The mobile connection can be a flip connection, a rotate connection, a folding connection, or a telescopic connection.

[0125] For example, a telescopic tube can be installed between the nasal breathing acquisition component 440 and the mouth breathing acquisition component 470 to allow for flexible adjustment of the distance between them. The telescopic tube can adopt an inner and outer sleeve design, with the outer layer fixed and the inner layer retractable.

[0126] For example, a hinge is provided between the nasal breathing acquisition component 440 and the mouth breathing acquisition component 470, so that the two components can be rotated around the axis of the hinge.

[0127] In the mobile state, the mouth breathing acquisition component 470 can be adjusted to a position near the user's mouth to collect the user's mouth breathing data.

[0128] Position adjustment can be based on image recognition, which involves acquiring an image of the user's mouth, obtaining the current position of the user's mouth, and adjusting the mouth breathing acquisition component 470 to the target position accordingly.

[0129] The mouth breathing acquisition assembly 470 includes at least an airflow sensor, which can be mounted on a similar acquisition plate as a base support.

[0130] Optionally, the breathing detection structure 400 includes a level, such as an electronic level, to help determine the user's sleeping posture, specifically whether they are lying on their back, side, or stomach.

[0131] In this embodiment, the level is horizontally integrated inside the movable connector 460 that connects the nasal breathing acquisition component 440 and the mouth breathing acquisition component 470. Taking the electronic level as an example, its working principle is based on the real-time perception of the device's own spatial posture. It adopts the three-axis acceleration sensing principle and uses the built-in microelectromechanical system (MEMS) sensor to measure the component ratio of gravitational acceleration on the three orthogonal axes in real time, and dynamically calculates the tilt angle of the device relative to the horizontal reference plane.

[0132] When the user is in a supine position, with the face facing upwards and the 460-degree axis of the moving connector parallel to the horizontal plane, the level instrument detects that the gravitational acceleration component perpendicular to the user's body surface mainly acts on the vertical axis (Z-axis), while the acceleration component of the horizontal axis (X / Y-axis) approaches zero.

[0133] When the user rolls over to a side-lying position, the position of the moving connector 460 changes, and the level's detection data also changes accordingly, with the horizontal axis acceleration component increasing significantly and the vertical axis component decreasing accordingly.

[0134] By analyzing the data changes under different sleeping positions, the system can determine the user's sleeping position.

[0135] Based on the data collected by the level, the tilt angle and direction vector of the level can also be calculated. This part of the calculation can be obtained using existing algorithms, such as the data fusion algorithm of gyroscope and accelerometer, which will not be elaborated here.

[0136] Considering that in actual implementation, even if the user is in a supine position, the level may not be completely horizontal and may have a certain tilt angle, therefore, a threshold range for the tilt angle can be preset.

[0137] For example, a tilt angle fluctuating within ±8° is considered a reasonable physiological postural adjustment for a supine position. Only when the tilt angle exceeds this range is it determined to be a lateral decubitus position.

[0138] If the sensor detects a significant shift in the Z-axis gravity component, it indicates that the person is face down and is directly identified as sleeping in a prone position.

[0139] Furthermore, the threshold range of tilt angle is combined with the range of maintenance time to help determine sleep posture.

[0140] For example, if a tilt angle exceeding 15° is continuously detected and maintained for more than 5 seconds, a side-lying posture determination is triggered.

[0141] This invention provides an intervention method implemented using the aforementioned sleep apnea syndrome intervention device, such as... Figure 1 As shown, it includes the following steps: S1 supports the user's jawline.

[0142] This step is achieved through the mandibular support structure 200.

[0143] S2 collects the user's breathing data through the breathing detection structure 400, and the control center determines whether the user's breathing status is normal based on the breathing data.

[0144] Each item in the respiratory data is compared to its corresponding preset standard range. A score is obtained for each item according to a preset scoring standard. These scores are then aggregated to obtain a comprehensive score. Based on the scoring standard corresponding to the comprehensive score, a result is determined on the user's respiratory status. As an example, and not a limitation, the preset standard ranges are as follows: Normal respiratory rate: The normal respiratory rate for adults is generally between 12 and 20 breaths per minute.

[0145] Normal tidal volume: The normal tidal volume for adults is generally 400 to 600 milliliters (ml).

[0146] Breathing pattern: even, without obvious breathing difficulties, with relatively balanced inhalation and exhalation times.

[0147] Inhalation time: 1:1.5 to 1:2.5 Note that the above preset standard range and corresponding scoring criteria are for illustrative purposes only and are not intended as limitations for specific implementation. In specific implementation, additional settings and adjustments can be made as needed.

[0148] For example, user A.

[0149] First, respiratory rate: Monitoring data showed an average respiratory rate of 20 breaths / minute (normal range 12-20 breaths / minute).

[0150] Scoring rules: <12 breaths (bradyspnea): +5 points 12-20 times (normal): 0 points 21-25 times (mild abnormality): +3 points ≥26 times (moderately abnormal): +7 points ≥35 times (severe abnormality): +10 points Scoring result: 26 times exceeding the upper limit of the normal range by 30%, which is considered normal, 0 points.

[0151] Secondly, tidal volume: The average tidal volume is 280ml (normal range 400~600ml), and the lowest instantaneous value is only 180ml.

[0152] Scoring rules: 300~399ml (slightly reduced): +3 points 250~299ml (moderate decrease): +5 points <250ml (severe reduction): +8 points 600ml (overventilation is scored separately for each disease). Scoring result: 280ml is 30% below the lower limit of normal, which is considered a moderate decrease, +5 points.

[0153] Third, the inhalation / exhalation time ratio: the inhalation time is 1.2 seconds and the exhalation time is as long as 4.3 seconds, with a ratio of 1:3.6 (normal is 1:1.5~1:2.5).

[0154] Scoring rules: 1:2.6~1:3.5 (slightly prolonged): +3 points 1:3.6~1:4.5 (moderate prolongation): +5 points 1:4.5 (Severe Delay): +7 points Scoring results: The ratio 1:3.6 exceeds the standard by 44%, which is considered moderate prolongation, +5 points.

[0155] Fourth, apnea events: A total of 8 apnea events (a single airflow interruption lasting ≥10 seconds) were detected, averaging 1.3 events per hour.

[0156] Scoring rules: 0-4 times per hour: +1 point per instance ≥5 times per hour: +2 points per time Scoring results: A total of 8 single pause events, accumulating 8 points.

[0157] Overall score = respiratory rate (0) + tidal volume (5) + inspiratory-to-expiratory ratio (5) + apnea events (8) = 18 points Comprehensive Judgment Rules: 0-10 points: Normal respiratory function 11-20 points: Mild functional impairment 21-30 points: Severe abnormality Based on a comprehensive score of 18, which falls into the "mild functional impairment" range, the control center determined that the user had frequent apnea events accompanied by low tidal volume and significantly prolonged expiratory phase, which is an abnormal respiratory state.

[0158] Furthermore, the breathing status is assessed by combining the sleep posture determination results obtained through a level.

[0159] The effects of supine and lateral sleeping positions on sleep apnea differ significantly. When lying supine, due to gravity, the base of the tongue and soft palate tend to fall backward, directly compressing the upper respiratory tract and causing airway narrowing or even complete obstruction. In this situation, airflow is restricted or interrupted, easily triggering hypoventilation or sleep apnea events.

[0160] When lying on your side, the direction of gravity's pull on the base of the tongue and soft palate changes, reducing the probability of airway collapse. At the same time, lying on your side reduces pressure on the airway from the pharyngeal tissues, improving ventilation efficiency.

[0161] Sleep posture is included as a scoring factor in the overall score above.

[0162] As an example, the corresponding scoring criteria are set as follows: Side-lying sleeping position: +2 points.

[0163] While lying on one's side reduces the risk of airway obstruction, it may still cause a decrease in tidal volume due to limb compression of the chest cavity, especially in obese patients, so appropriate scoring is necessary.

[0164] Supine position: +5 points Because lying supine can easily cause the tongue to fall back and the airway to narrow, increasing the risk of apnea, a higher abnormal score is assigned.

[0165] Prone sleeping position: +8 points.

[0166] Lying face down with your mouth and nose facing the pillow poses the highest risk of airway obstruction.

[0167] If user A's level detects a tilt angle of 5° for 1 minute, and the current sleeping position corresponds to a supine position, then +5 points are awarded.

[0168] The score based on the user's breathing data is the first score, while the score based on the user's sleeping posture is the second score.

[0169] The first and second scores are weighted and calculated as follows: Overall score = K1 * first score + K2 * second score.

[0170] K1 and K2 correspond to the weighting coefficients of the first score and the second score, respectively, and can be set according to different actual situations.

[0171] In this embodiment, assuming that K1 and K2 are both 1, the total score is 18 + 5 = 23 points, which falls into the "severely abnormal" range, corresponding to the judgment that the user has an abnormal breathing state.

[0172] When the breathing detection structure is rotatably connected to the chin support structure through the second adjustment structure, S2 also includes collecting the relative distance data between the breathing detection structure 400 and the user's mouth and nose, comparing the distance data with a preset threshold, and triggering an adjustment operation on the position of the breathing detection structure 400 when the distance data is greater than the preset threshold.

[0173] When S3 determines that the user is in an abnormal breathing state, the control center triggers the first adjustment structure 300 to elevate the mandible relative to the mandibular support structure 200, such as... Figure 4 As shown.

[0174] The action of elevating the jaw restores airway patency through at least one of the following mechanisms: When the jaw is raised, muscles such as the genioglossus and geniohyoid muscles are stretched, causing the hyoid bone to move forward and the base of the tongue to move away from the posterior pharyngeal wall. This relieves the pressure on the airway caused by the tongue falling back, thus opening the glottis and making it easier for air to enter the lungs. This allows oxygen to enter the lungs more smoothly.

[0175] During respiration, the expansion of the lungs creates negative pressure within the thoracic cavity, which helps draw air into the lungs. When the airway is open, this negative pressure effect effectively draws air into the lungs. When the chin is raised, the head tilts back, extending the cervical spine and changing the angle between the posterior wall of the pharynx and the soft palate. This increases the diameter of the airway, reducing airflow resistance and enhancing this negative pressure effect, making it easier for air to flow in.

[0176] Optionally, S2 further includes driving the rolling assembly 320 to move above the first adjustment structure 300 and intervening between the user's chin and the first adjustment structure 300; and / or, S2 further includes inflating the soft bag 330 with air and performing a jet operation on the user's chin area through the air outlet 331.

[0177] Optionally, after S3 completes the mandibular elevation operation, it also includes repeating step S2 again, collecting the user's breathing data through the breathing detection structure 400, determining the user's breathing status, and if the user's breathing status is still abnormal, further increasing the height of the mandible relative to the mandibular support structure 200 through the first adjustment structure 300 to strengthen the mandibular elevation effect of the first adjustment structure 300.

[0178] If it is determined that the user's breathing status has returned to normal, the first adjustment structure 300 lowers the user's chin relative to the chin support structure 200, thereby reducing the lifting support effect of the first adjustment structure 300 on the user's chin.
