Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical devices, specifically a nasal cavity dilator for snoring and an intelligent snoring control system based on snoring sound recognition. Background Technology
[0002] Obstructive sleep apnea is a common sleep-disordered breathing condition. Its pathophysiological basis lies in the repeated collapse or obstruction of the upper airway during sleep. The human upper airway is a continuous soft tissue passage from the nasal cavity to the larynx, with the nasopharynx, palatopharynx, and base of the tongue being the key areas most prone to narrowing or obstruction. When an individual sleeps in a supine position, due to gravity and decreased muscle tone, the base of the tongue and soft palate tend to shift posteriorly, resulting in a significant reduction in the cross-sectional area of the pharynx. Airflow passing through this area causes soft tissue vibration, manifesting as snoring. If the obstruction worsens, it can lead to apnea, decreased blood oxygen saturation, and sleep fragmentation. Epidemiological studies have shown that obesity, adenoid and tonsil hypertrophy, craniofacial structural abnormalities, advanced age, and neurological diseases can all significantly increase the risk of upper airway obstruction.
[0003] To address the aforementioned issues, current clinical practice primarily employs the following intervention methods: Nasal dilators are inserted into the nasal vestibule or nasal threshold to mechanically expand the nasal passage, but their range of action is limited and cannot resolve obstruction at the palatopharyngeal and tongue root levels. Oral appliances expand the pharyngeal cavity by moving the mandible forward or pulling the tongue, but long-term use can easily cause adverse reactions such as temporomandibular joint discomfort, abnormal salivation, and tooth displacement. Continuous positive airway pressure (CPAP) is considered the "gold standard" of non-surgical treatment, delivering positive pressure airflow through a mask to maintain airway patency; however, its large size, poor wearing comfort, and noise issues generally lead to low patient compliance. For some critically ill patients, surgical procedures such as uvulopalatopharyngoplasty can be chosen, but these procedures are highly invasive, have a long recovery period, and carry the risk of postoperative scar contracture leading to airway restenosis.
[0004] The shortcomings of existing technologies lie in the lack of a nasal dilation device that can simultaneously address insertion safety, wearing comfort, and multi-site support functions. Traditional devices, due to their fixed tip shape and large cross-section, are prone to friction with the nasopharyngeal mucosa and may even puncture the posterior pharyngeal wall during insertion, posing a high bleeding risk to patients requiring anticoagulation therapy or with abnormal coagulation function. Furthermore, existing devices mostly employ a static support design, failing to dynamically adjust the support strength according to the severity of the patient's snoring and respiratory rhythm, making it difficult to achieve graded intervention for mild and severe snoring. In addition, existing functions are relatively limited, failing to simultaneously meet multiple clinical needs such as nasal dilation, soft palate support, tongue base fixation, and prevention of peripharyngeal soft tissue collapse. Summary of the Invention
[0005] To address the aforementioned technical problems, this invention provides a nasal cavity dilation anti-snoring device and an intelligent anti-snoring system based on snoring sound recognition, thereby solving the problem of mucosal friction damage that easily occurs during device insertion in the prior art.
[0006] This invention provides a nasal cavity dilation anti-snoring device, comprising:
[0007] An arc-shaped soft body has a flexible tube A end and a flexible tube B end, wherein the flexible tube A end is inserted into the nasal cavity and extends into the pharynx, and the flexible tube B end is located on the outside of the nasal cavity;
[0008] The arc-shaped soft body has a preset curvature, and thus has a small bend side C and a large bend side D of the hose;
[0009] A bending control, the bending control including a traction wire, both ends of the traction wire being located outside the B end of the hose;
[0010] Preferably, the traction wire enters the interior of the arc-shaped soft body from the B end of the flexible tube and extends towards the A end of the flexible tube through the inner wall of the small bend side C of the flexible tube; the traction wire forms a turning point at the end of the small bend side C of the flexible tube at the A end, and after turning back at the turning point, the traction wire passes through the inner wall of the small bend side C of the flexible tube again and extends towards the B end of the flexible tube, so that the traction wire is U-shaped and passes through the arc-shaped soft body;
[0011] By pulling the two ends of the traction wire from end B of the hose, end A of the hose is bent toward the small bend side C of the hose;
[0012] Pulling either end of the traction wire causes the entire traction wire to be extracted from the curved soft body.
[0013] The way in which the traction wire 2 wraps around the end A of the hose to form a wrapping structure is as follows: after the traction wire 2 wraps around the end C of the hose at the small bend side of the hose at the end A of the hose at least half a turn, both ends extend back towards the end B of the hose from the same thread hole or different thread holes.
[0014] Preferably, the A end of the flexible tube is provided with multiple threading holes, and the traction wire 2 passes through the multiple threading holes in sequence to form a multi-point wrapping structure at the A end of the flexible tube.
[0015] Preferably, the arc-shaped soft body is provided with several flexible isosceles triangular films. The isosceles triangular films are made of stretchable soft films, and each isosceles triangular film is divided into a hollow area and a closed area. The two corners of the hollow area are located at the A end of the flexible tube, and the closed area is located near the B end of the flexible tube. The hollow area is used to connect the pharynx and the other nasal cavity for airflow after insertion.
[0016] Preferably, it also includes an expansion control, which includes several steel wires and a steel ring fixed to the inner wall of the B end of the hose. The steel wires are rotatably arranged with the steel ring as a fulcrum. One end of the steel wire extends to the A end of the hose, and the other end extends to the outside of the B end of the hose.
[0017] The section of the steel wire near end B of the hose is rigid, and the section near end A of the hose is flexible.
[0018] The arc-shaped soft body has a natural state and an expanded state:
[0019] In its natural state, the arc-shaped soft body becomes conical due to the contraction of the isosceles triangular membrane, and the diameter of its flexible tube A end is smaller than the diameter of its flexible tube B end.
[0020] When a driving force is applied to the end of the steel wire extending from the B end of the hose, the steel wire rotates around the steel ring as an axis, and the driving force is transmitted through the rigid section, driving the flexible section of the steel wire at the A end of the hose to open. By stretching the isosceles triangular film, the arc-shaped soft body is switched from a conical shape to a cylindrical shape, and the diameter of the A end of the hose is expanded to be basically the same as that of the B end of the hose.
[0021] When the driving force is removed, the arc-shaped soft body returns to a conical shape due to the elastic restoring force of the isosceles triangular membrane.
[0022] Preferably, the plurality of steel wires include hollow steel wires disposed within the large bend side D of the hose and solid steel wires disposed at other circumferential positions.
[0023] Preferably, it also includes an airbag support expansion component, the airbag support expansion component including an airbag, the airbag being annular and fixedly installed on end A of the hose;
[0024] The airbag has a naturally inflated state and a fully inflated state:
[0025] When naturally inflated, the air bladder provides basic support for the soft palate, the base of the tongue, and the soft tissues around the pharynx.
[0026] When inflated, the airbag provides enhanced support to the aforementioned areas;
[0027] The hollow steel wire located in the large bend of the hose (D) is connected to the airbag so that air can be pumped into the airbag through the hose (B end).
[0028] When the airbag is not inflated, it fits against the outer wall of the A end of the hose. When it is naturally inflated, it expands into a ring shape. When the inflation is increased, the degree of expansion increases, which causes the B end of the hose to open into a trumpet shape.
[0029] Preferably, it also includes a pressure sensor for monitoring the pressure inside the airbag to adjust the inflation volume based on pressure feedback.
[0030] Preferably, it also includes an adjustment control, which includes a cable tie, and one end of the plurality of steel wires extending out of the B end of the hose is fixed to the cable tie;
[0031] When the cable tie is tightened, the cable tie pries the end of the steel wire located at end B of the hose, applying the driving force;
[0032] When the cable tie is loosened, the driving force is removed.
[0033] Preferably, the cable tie has a first locking point and a second locking point;
[0034] At the first checkpoint, the cable tie is in a loose state and the arc-shaped soft body maintains a natural conical shape;
[0035] When the cable tie is tightened to the second locking point, the arc-shaped soft body switches to the expanded cylindrical state.
[0036] The present invention also provides an intelligent anti-snoring system based on snoring recognition, including the above-mentioned nasal cavity dilation anti-snoring device, and further comprising:
[0037] The AI control system is used to generate control signals based on the snoring recognition results to adjust the inflation volume of the airbag.
[0038] When the AI control system detects mild snoring, it controls the inflation device to maintain a natural inflation state.
[0039] When the AI control system detects a risk of severe snoring or airway collapse, it controls the inflation device to switch to a higher inflation state.
[0040] Compared with the prior art, the present invention has the following beneficial effects:
[0041] By organically combining the arc-shaped soft body with the U-shaped traction wire, the anti-snoring device can bend safely and precisely in the nasopharynx, allowing the A end of the tube to actively avoid the posterior pharyngeal wall during insertion, thus fundamentally avoiding mechanical damage to the mucosa caused by traditional instruments.
[0042] By setting an isosceles triangular film on the main body and using a steel wire expansion control with a steel ring as the fulcrum, a controllable morphological evolution mechanism between a conical shape and a cylindrical shape is constructed: in the natural state, it is a slender cone shape at the front end, which significantly reduces the contact area and frictional resistance during insertion and greatly improves wearing comfort; in the traction expansion state, it switches to a uniform cylindrical shape, which effectively expands the nasal cavity breathing space and ensures that the airway is unobstructed.
[0043] This invention designs the steel wire inside the large bend as a hollow structure and connects it to the annular airbag at the front end, forming a flexible support channel that reaches the soft palate and the base of the tongue. Through graded inflation, it can suppress soft palate vibration, prevent the tongue base from falling back, and support the collapse of peripharyngeal soft tissue. After inflation, the B end of the flexible tube opens in a trumpet shape, further optimizing airflow characteristics. With the help of a pressure sensor and an AI control system, it can automatically adjust the inflation force according to the snoring recognition results, realizing personalized graded intervention for mild and severe snoring, so that the support force is always maintained within the physiological comfort range.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0049] Example 1: This example provides a nasal cavity dilator for anti-snoring, such as... Figure 1 As shown, it mainly includes an arc-shaped soft body 1 and a bending control.
[0050] The curved soft body 1 is integrally molded from medical-grade elastic silicone material. Its shape is adapted to the physiological curvature of the human nasopharynx and has a preset gradient curvature. The curved soft body 1 has a flexible tube A end and a flexible tube B end. The flexible tube A end is used to be inserted into the nasal cavity and extend into the pharynx, while the flexible tube B end is located on the outside of the nasal cavity during use. Due to its curvature, the curved soft body 1 naturally forms two sides: the flexible tube small bend side C located inside the curvature and the flexible tube large bend side D located outside the curvature. The flexible tube A end is designed with a blunt, smooth tip to avoid damage to the nasal cavity or pharyngeal mucosa during insertion.
[0051] The bending control includes a traction wire 2; in order to achieve precise bending and avoid puncturing the posterior pharyngeal wall, the traction wire 2 adopts a special insertion method; both ends of the traction wire 2 are located outside the B end of the flexible tube, which is convenient for the operator to pull; the traction wire 2 enters the interior of the arc-shaped soft body 1 from the B end of the flexible tube, and extends through the inner wall of the small bend side C of the flexible tube to the A end of the flexible tube; specifically, a small tunnel-type threading hole is preset on the arc-shaped soft body 1 at the small bend side C of the flexible tube, and the traction wire 2 can slide through the threading hole.
[0052] When the traction wire 2 reaches the end of the hose at the small bend C of the hose at end A, a turning point is formed;
[0053] In a preferred embodiment, the traction wire 2 wraps around the end A of the hose at least once at the reversal point to form a wrapping structure around the end A of the hose, and then extends back towards the end B of the hose from the same thread hole.
[0054] In another preferred embodiment, a plurality of threading holes are provided on the A end of the hose, and the traction wire 2 passes through the plurality of threading holes in sequence to form a multi-point wrapping structure at the A end of the hose;
[0055] Regardless of the wrapping method used, the traction wire 2 will pass through the inner wall channel of the small bend side C of the hose again after the folding back and extend towards the end B of the hose, so that both ends of the traction wire 2 are eventually located outside the end B of the hose. The entire traction wire 2 is U-shaped and passes through the arc-shaped soft body 1 inside the small bend side C of the hose.
[0056] During use, the operator gently pulls both ends of the traction wire 2 from end B of the flexible tube. Due to the tightening effect of the U-shaped wire and the wrapping effect of the traction wire 2 around end A of the flexible tube, end A of the flexible tube will bend towards the small bend side C of the flexible tube. This wrapping structure makes the traction force distribution more uniform and the bending control more precise, so that the front end of end A of the flexible tube can effectively avoid the sensitive posterior pharyngeal wall and achieve safe insertion.
[0057] When it is necessary to remove the traction wire 2, the operator only needs to continuously pull either end of the traction wire 2, and the entire traction wire 2 will gradually slide out from the turning point and eventually be completely pulled out from the curved soft body 1; this design allows the traction wire 2 to be flexibly removed as needed, making it convenient to use.
[0058] Example 2: Based on Example 1, this example further adds an expansion function, such as... Figure 2-3 As shown.
[0059] like Figure 2 As shown, several flexible isosceles triangular films 3 are provided on the curved soft body 1. These isosceles triangular films 3 are made of stretchable soft film material (such as highly elastic silicone film) and are integrally connected with the main material of the curved soft body 1;
[0060] Each isosceles triangular membrane 3 is divided into two regions: a hollow area 31 and a closed area 32;
[0061] The two corners of the hollow area 31 are located near end A of the hose; the closed area 32 is located near end B of the hose, and the film in this area is continuous.
[0062] The hollow area 31 has an important airflow channel function: when the anti-snoring device is inserted into place, the hollow area 31 connects the pharynx and the other nasal cavity, so that the airflow inhaled from the mouth and the airflow inhaled from the other nasal cavity can flow smoothly into the main airway, ensuring the coordination and effectiveness of bilateral ventilation.
[0063] like Figure 3 As shown, this embodiment also includes an expansion control, which includes several steel wires 4 and a steel ring 6 fixed to the inner wall of the B end of the hose;
[0064] The steel wire 4 is rotatably mounted with the steel ring 6 as the fulcrum. One end of the steel wire 4 extends to the A end of the hose, and the other end extends to the outside of the B end of the hose.
[0065] The section of steel wire 4 near end B of the hose is rigid, while the section near end A of the hose is flexible.
[0066] The curved soft body 1 has a natural state and an expanded state:
[0067] In its natural state, without the application of driving force, the arc-shaped soft body 1 takes on a conical shape due to the self-contraction characteristics of the isosceles triangular membrane 3, with the diameter of the flexible tube A end being smaller than that of the flexible tube B end. The core purpose of this design is to reduce friction and damage during insertion. Because the diameter and cross-section of the flexible tube A end are small, the contact area and friction coefficient with the nasopharyngeal mucosa are significantly reduced, allowing it to pass through the narrow and tortuous nasopharyngeal passage in a "slipping" rather than "squeezing" manner, greatly reducing discomfort and the risk of mucosal damage during insertion.
[0068] Expanded state: such as Figure 2 and 3 As shown, when a driving force is applied to the end of the steel wire 4 that extends out of the hose B, the steel wire 4 rotates around the steel ring 6 as an axis, and the driving force is transmitted through the rigid section, driving the flexible section of the steel wire 4 at the hose A end to open outward, thereby stretching the isosceles triangular membrane 3, so that the arc-shaped soft body 1 changes from a conical shape to a cylindrical shape, and the diameter of its hose A end expands to be basically the same as that of the hose B end; the core purpose of this shape transformation is to expand the nasal cavity breathing space, support the airway patency, and provide a channel with the largest cross-sectional area for airflow;
[0069] When the driving force is removed, the arc-shaped soft body 1 automatically returns to a conical shape due to the elastic restoring force of the isosceles triangular membrane 3.
[0070] Example 3: Based on Example 2, this example further enhances the dynamic support function for the soft palate, the base of the tongue, and the soft tissues around the pharynx.
[0071] The steel wires 4 are specifically divided into two types: hollow steel wires 41 set in the large bend side D of the hose and solid steel wires 42 set in other circumferential positions; the hollow steel wires 41 have a through axial channel inside.
[0072] This embodiment also includes an airbag support expansion member, which includes an airbag, such as... Figure 2 As shown. The airbag is ring-shaped and fixedly installed on end A of the hose; in the uninflated state, the airbag fits tightly against the outer wall of end A of the hose, maintaining a low profile for easy insertion.
[0073] like Figure 3 As shown, the hollow steel wire 41 located inside the large bend of the hose D is connected to the airbag so that air can be pumped into the airbag through the B end of the hose; the hollow steel wire 41 itself constitutes an inflation path from the B end of the hose directly to the airbag; the operator can connect an inflation device (such as a syringe or a miniature air pump) through the hollow steel wire 41 interface at the B end of the hose to pump air into the airbag.
[0074] The airbag has a natural inflation state and a super-inflated state:
[0075] Natural inflation state: When inflated with the basic amount of gas, the airbag expands into a moderately inflated ring shape, causing the B end of the tubing to open into a trumpet shape. In this state, the airbag provides triple support: it supports the soft palate to prevent it from swinging with the airflow and generating high-frequency vibrations; it supports the base of the tongue to prevent it from falling back and obstructing the airway; and it supports the soft tissues around the pharynx to prevent them from collapsing and causing airway narrowing.
[0076] Increased inflation: Increasing the inflation volume further on top of natural inflation increases the degree of airbag expansion, causing the B end of the tubing to open into a larger trumpet shape; in this state, the airbag provides stronger support to the above-mentioned areas, which is suitable for patients with a high risk of airway collapse.
[0077] The design of the airbag inflating so that the B end of the hose opens into a trumpet shape not only enhances the support effect but also makes the airflow channel entrance wider.
[0078] Example 4: Based on Example 3, this example adds a control for locking the expansion state, such as... Figure 3 As shown.
[0079] This embodiment also includes an adjustment control unit, which includes a cable tie 5; one end of several steel wires 4 extending out of the flexible tube B is fixed to the cable tie 5, and the cable tie 5 has a first locking point and a second locking point.
[0080] When the cable tie 5 is at the first locking point, the cable tie 5 is in a relaxed state, the steel wire 4 is not pried, and the arc-shaped soft body 1 maintains its natural conical shape by the contraction of the isosceles triangular film 3.
[0081] When expansion is required, the operator tightens the cable tie 5, moves it to the second locking point and locks it. At this time, the cable tie 5 pries the end of the steel wire 4 located at the B end of the hose, thereby applying driving force. Through the leverage of the steel wire 4, the A end of the hose is opened, so that the arc-shaped soft body 1 is switched to the expanded cylindrical state.
[0082] When it is necessary to restore the natural state, the driving force can be removed by loosening the cable tie 5, and the arc-shaped soft body 1 will automatically return to the conical shape under the elastic restoring force of the isosceles triangular film 3.
[0083] Example 5: This example provides an intelligent anti-snoring system based on snoring recognition, which includes a nasal cavity dilation anti-snoring device according to any one of Examples 1 to 4, and an AI control system.
[0084] The AI control system includes:
[0085] Sound sensor: Used to collect sound signals during the user's sleep process in real time, especially snoring signals.
[0086] Pressure sensor: It is in fluid communication with the airbag or coupled with a pressure signal to monitor the real-time pressure inside the airbag.
[0087] Processor (such as MCU or DSP): electrically connected to the sound sensor and pressure sensor respectively.
[0088] Inflation / deflator (such as a miniature air pump and solenoid valve): connected to the air inlet of the hollow steel wire 41 and controlled by the processor.
[0089] The processor is configured to execute the following algorithm:
[0090] Snoring recognition and classification: It receives sound sensor signals and uses a preset algorithm to identify the intensity and frequency characteristics of snoring, thereby determining the severity of snoring (mild or severe).
[0091] Graded inflation control: Based on the recognition results, a control signal is generated to drive the inflation and deflation device to perform graded control of the airbag—when mild snoring is detected, the inflation device is controlled to maintain a natural inflation state; when severe snoring or airway collapse risk is detected, the inflation device is controlled to switch to a higher inflation state.
[0092] Pressure closed-loop feedback: During inflation, the pressure signal from the pressure sensor is continuously received and compared with the preset safety threshold range; when the pressure approaches the upper limit, inflation is stopped or depressurization is performed; when the pressure is below the lower limit, air is added to ensure that the pressure of the airbag on the soft palate, tongue base and surrounding soft tissues of the pharynx is always maintained within a comfortable and effective range.
[0093] Through the aforementioned intelligent control, the system can achieve preventive and adaptive intervention for snoring and upper airway obstruction, automatically adjusting the support strength according to the patient's specific condition to achieve personalized treatment.
[0094] The nasal cavity dilation anti-snoring device and intelligent system of the present invention, due to its unique design, has broad application prospects. In addition to conventional snoring treatment, it is particularly suitable for the following high-risk or special populations:
[0095] Perioperative patients: Used for temporary ventilation support during the extubation transition period after general anesthesia to prevent the tongue from falling back.
[0096] For women in late pregnancy: When snoring and shortness of breath occur, non-invasive oxygen delivery and airway support are provided to ensure the safety of both mother and baby.
[0097] For patients with cardiovascular and cerebrovascular diseases, especially those who require anticoagulation therapy (prone to bleeding) and are obese or have a short neck, it can be used as a safe ventilation device to preserve spontaneous breathing when sedation is required for interventional treatment.
[0098] Pediatric patients: Used to prevent mouth breathing caused by adenoid hypertrophy, which can eventually develop into adenoid facies.
[0099] For patients with respiratory diseases: It can be used in conjunction with respiratory filtration devices, heating and humidification devices or nebulizers to administer medication, provide protection or relieve discomfort.
[0100] End-of-life care: Providing relatively comfortable non-invasive ventilation or oxygen supply for patients with advanced cancer and other conditions, thereby improving their quality of life at the end of their lives.
[0101] In summary, this invention provides a safe, comfortable, and intelligent upper respiratory tract management solution through the organic combination of an arc-shaped main body, a U-shaped bending control, an isosceles triangular film, a steel wire expansion control with a steel ring as the fulcrum, an airbag support, and an intelligent AI control system.

Any changes, modifications, substitutions and variations made by those skilled in the art to the above embodiments within the scope of the present invention should be included within the protection scope of the present invention.
