Description

Technical Field

[0001] The utility model relates to the field of medical instruments, more specifically to the field of oral appliances, and in particular to an anti-snoring device and an anti-snoring device system. Background Art

[0002] Snoring is a common sleeping phenomenon. Up to now, most people still think that snoring is commonplace and do not take it seriously. Some people even regard snoring as a sign of good sleep. In fact, snoring is the enemy of health. Snoring can lead to daytime sleepiness, fatigue, inattention, headache, decreased work ability, etc. Severe snoring is often accompanied by sleep apnea syndrome. Snoring can even cause repeated pauses in breathing during sleep, resulting in severe hypoxia of the brain and blood, forming hypoxemia, and inducing high blood pressure, cerebrocardia, arrhythmia, myocardial infarction, angina pectoris, etc., seriously affecting the patient's health.

[0003] There are many reasons for snoring, most of which are caused by airway obstruction. The nasal cavity and oral cavity are connected to the airway. When a person is asleep, the airway tissue may collapse due to muscle relaxation, mandibular retraction, and tongue falling back, causing airway obstruction. Especially for obese people, their airways are usually narrower, which makes them more prone to airway obstruction. One way to open the airway is to stretch the mandible forward to increase the muscle tension of the throat, tongue and soft palate, thereby opening the airway that collapses due to muscle relaxation during sleep. Therefore, the way to stop snoring caused by this reason is to pull the mandible forward to the ideal position to open the airway.

[0004] In recent years, in the field of orthodontics, various orthodontic manufacturers have gradually combined anti-snoring treatment with invisible shell-like dental appliances. A protrusion is set in the area of ​​the maxillary shell-like dental appliance close to the front teeth, and a connector is set in the area of ​​the mandibular shell-like dental appliance close to the back teeth. One end of the connector is connected to the mandibular shell-like dental appliance, and the other end is provided with a hook. When wearing, the hook is hooked onto the protrusion to complete the installation. After being worn on the upper and lower jaw dentition, the patient's lower jaw can be kept in a forward position, thereby opening the airway to suppress snoring.

[0005] However, the inventors have found in clinical cases that many snoring patients have other oral activities to varying degrees during sleep, such as opening and closing the mouth, which can cause the hook to "unhook", leading to treatment failure. This can even put pressure on patients, who worry that their involuntary oral activities at night will cause the snoring device to "unhook", causing the mandible to move upward in the sagittal plane and return to its original state, resulting in a prolonged treatment period or directly leading to treatment failure, thereby increasing the psychological burden on patients.

[0006] Therefore, it is necessary to provide a snoring stopper that can stop snoring without affecting the patient's oral activity. Utility Model Content

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the various embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in each embodiment of the utility model, many technical details are proposed in order to enable readers to better understand the utility model. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection of the utility model can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the utility model.

[0041] Directional terms such as "upper", "lower", "left", and "right" used in the description herein are directions in the drawings and do not refer to special limitations. Unless otherwise specified and limited, the term "connection" in this article should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, and can be directly connected or indirectly connected through an intermediate medium.

[0042] The "posterior tooth area" mentioned in each embodiment of the present invention is defined according to the classification of teeth in the second edition of "Introduction to Stomatology" published by Peking University Medical Press, pages 36-38, including premolars and molars, which are teeth 4-8 in the FDI marking method, and teeth 1-3 in the anterior tooth area in the FDI marking method. The teeth in the anterior tooth area include central incisors, lateral incisors and canines.

[0043] As can be seen from the background technology, although orthodontic manufacturers have tried to combine anti-snoring devices with invisible shell-shaped dental instruments, the problems existing in the current anti-snoring devices are: many snoring patients will have other oral activities to varying degrees during sleep, such as opening and closing the mouth, which will cause the hook part to "unhook", thereby leading to treatment failure. This may even bring pressure to the patients, who worry that their involuntary oral activities at night will cause the anti-snoring device to "unhook", causing the mandible to move upward in the sagittal plane and return to its original state, resulting in a prolonged treatment period or directly leading to treatment failure, thereby increasing the psychological burden on the patients.

[0044] Based on this, the applicant proposed an anti-snoring device, comprising a first shell-shaped dental appliance, a second shell-shaped dental appliance, and a connecting rod movably connected to the buccal side of the first shell-shaped dental appliance and the buccal side of the second shell-shaped dental appliance; the first shell-shaped dental appliance and the second shell-shaped dental appliance are respectively shells that conform to the shape of the upper and lower jaw teeth of the human body, and include a plurality of cavities arranged in a U shape for accommodating a plurality of teeth; the buccal side of the first shell-shaped dental appliance near the front teeth and the buccal side of the second shell-shaped dental appliance near the back teeth are respectively provided with connecting holes; the two ends of the connecting rod are respectively provided with connecting parts, the first end of the connecting part is connected to the connecting rod, and the second end of the connecting part is provided with a limit The connecting portion escapes from the limiting piece of the connecting hole along the distal tooth direction, and the limiting piece is clamped with the inner surface of the cavity where the connecting hole is located, and a predetermined space is provided between the inner surface of the cavity where the connecting hole is located and the tooth surface of the tooth accommodated in the cavity where the connecting hole is located, for accommodating the limiting piece; wherein, the connecting portion passes through the connecting hole, and connects the connecting rod to the first shell-shaped dental instrument and the second shell-shaped dental instrument, so as to limit the relative movement range of the first shell-shaped dental instrument and the second shell-shaped dental instrument in the sagittal direction, thereby ensuring that the snoring stopper can stop snoring within the relative movement range without affecting the patient's opening and closing mouth activities, thereby eliminating the patient's psychological burden and helping to achieve the snoring stopper effect.

[0045] Please see Figures 1 to 5 As shown, the snoring stopper 100 of the present application comprises a first shell-shaped dental appliance 1, a second shell-shaped dental appliance 2 and a connecting rod 3, wherein the two ends of the connecting rod 3 are respectively movably connected to the buccal side of the first shell-shaped dental appliance 1 and the buccal side of the second shell-shaped dental appliance 2; the first shell-shaped dental appliance 1 and the second shell-shaped dental appliance 2 are respectively shells conforming to the shape of the upper and lower jaw teeth of the human body, and include a plurality of cavities 10 arranged in a U shape for accommodating a plurality of teeth. In the present application, after the connecting rod 3 connects the first shell-shaped dental appliance 1 and the second shell-shaped dental appliance 2, the two ends of the connecting rod 3 can respectively rotate around the normal axis of the buccal side of the shell-shaped dental appliance where it is located, so as to limit the relative motion range of the first shell-shaped dental appliance 1 and the second shell-shaped dental appliance 2 in the sagittal direction X. Through the design of the present application, the two ends of the connecting rod 3 are movably connected to the buccal side of the first shell-shaped dental appliance 1 and the buccal side of the second shell-shaped dental appliance 2, respectively, so that the patient's lower jaw can be brought into a position range that can open the patient's airway to suppress snoring, and the patient's mouth opening and closing activities will not be affected, so that the patient's upper and lower jaws can move in a predetermined relative range in the sagittal direction X, thereby improving the patient's comfort.

[0046] In the present application, a connecting hole 20 is respectively provided at the buccal position of the first shell-shaped dental instrument 1 near the front teeth and at the buccal position of the second shell-shaped dental instrument 2 near the back teeth, so that the connecting portion 30 can pass through the connecting hole 20; accordingly, connecting portions 30 are respectively provided at both ends of the connecting rod 3, a first end 31 of the connecting portion 30 is connected to the connecting rod 3, and a limiting member 33 is provided at the second end 32 of the connecting portion 30, and the limiting member 33 is clamped with the inner surface of the cavity 10 where the connecting hole 20 is located, so as to limit the connecting portion 30 from escaping from the connecting hole 20 along the distal tooth direction. In addition, the connecting portion 30 and the connecting rod 3 can be manufactured as one piece. For example, when the limiting member 33 passes through the connecting hole 20, it can undergo elastic deformation to pass through the connecting hole 20. After passing through the connecting hole 20, the limiting member 33 returns to its original shape and is clamped on the inner surface of the cavity 10 where the connecting hole 20 is located. The connecting portion 30 and the connecting rod 3 can also be manufactured separately. The connecting rod 3 and the connecting portion 30 are manufactured separately. After the connecting portion 30 passes through the connecting hole 20, the connecting portion 30 is fixed to the connecting rod 3 by a fixing method such as bonding or welding. Alternatively, the connecting rod 3 and the connecting portion 30 are designed as a detachable structure for easy disassembly and replacement. There are no restrictions in the present application. In the present application, the applicant takes into account the patient's comfort and designs the inner surface of the cavity 10 where the connecting hole 20 is located to form a certain predetermined space 40 with the tooth surface 50 of the tooth accommodated in the cavity 10. The predetermined space 40 can accommodate the limiter 33 to prevent the limiter 33 from applying a force in the lingual direction to the tooth covered by it when wrapped by the inner surface of the cavity 10. The force acting on the tooth will, on the one hand, compress the patient's teeth and reduce the patient's comfort, and on the other hand, may cause the tooth to move unexpectedly.

[0047] In addition, in some embodiments, Figure 1 As shown, in the anti-snoring device 100, the first shell-shaped dental appliance 1 is a maxillary shell-shaped dental appliance worn on the patient's maxillary dentition, and the second shell-shaped dental appliance 2 is a mandibular shell-shaped dental appliance worn on the patient's mandibular dentition. Figure 2 As shown, in the anti-snoring device 200, the first shell-shaped dental appliance 1 can also be a mandibular shell-shaped dental appliance worn on the patient's mandibular dentition, and the second shell-shaped dental appliance 2 can be a maxillary shell-shaped dental appliance worn on the patient's maxillary dentition.

[0048] In one embodiment, please continue to refer to Figure 5, the outer contour dimension L1 of the stopper 33 is greater than the aperture dimension L of the connecting hole 20. Regardless of how the stopper 33 is formed and what structure it presents, after the connecting rod 3 is installed on the first shell-shaped dental instrument 1 and the second shell-shaped dental instrument 2, the stopper 33 can be stably clamped on the inner surface of the cavity 10. In this embodiment, by designing that the outer contour dimension of the stopper 33 is greater than the aperture dimension L of the connecting hole 20, the outer contour of the stopper 33 can be clamped on the inner surface of the cavity 10 around the connecting hole 20 to prevent the stopper 33 from coming out of the connecting hole 20.

[0049] In one embodiment, see Fig.19 and Fig. 20 As shown, the predetermined space is a cavitation boss 60 formed by the buccal surfaces of the first shell-shaped dental instrument 1 and the second shell-shaped dental instrument 2 protruding toward the distal tooth direction, the connecting hole 20 is arranged on the side wall of the cavitation boss 60 in the distal tooth direction, and the cavitation boss 60 has a receiving cavity for receiving the limiting member 33. The receiving cavity is connected to the connecting hole 20, and the structure of the connecting hole 20 satisfies: the limiting member 33 can pass through (can pass through in a compressed state, or can pass through without compression) the connecting hole 20 to be received in the receiving cavity, and when the limiting member 33 is received in the receiving cavity, the connecting hole 20 can limit the limiting member 33 from escaping from the receiving cavity along the distal tooth direction.

[0050] Through the design of the present application, the connection hole 20 on the shell-shaped dental instrument and the limiting member 33 on the connection part 30 are limitedly matched, and through the elastic deformation or plastic deformation of the limiting member 33, after the connection part 30 is inserted into the connection hole 20, due to the limiting effect of the limiting member 33, it can be inserted but not pulled out, which can not only limit the connection part 30 from slipping out of the connection hole 20 along the distal tooth direction, but also make the installed connection rod 3 not easy to be removed or shifted during use, so as to achieve the therapeutic purpose of stopping snoring, and avoid the problem of users dismantling it privately or losing accessories due to repeated disassembly and assembly. The specific implementation of the limiting member 33 will be described in detail in the following embodiments.

[0051] In one embodiment, see Figures 6 to 10As shown, the outer contour dimension L2 of the portion 331 proximal to the insertion end of the limiter is smaller than the aperture dimension L of the connecting hole 20, and the outer contour dimension L3 of the portion 332 of the limiter away from the insertion end is larger than the aperture dimension L of the connecting hole 20. When the connecting portion 30 is inserted into the connecting hole 20, the limiter 33 is retracted and gathered inwardly toward the connecting portion 30 under the constraint of the connecting hole 20, so that the connecting portion 30 passes through the connecting hole 20 and is clamped with the inner surface of the cavity 10 where the connecting hole 20 is located, so as to limit the movement of the connecting portion 30 along the distal tooth direction.

[0052] It is further explained that the inner surface of the cavity 10 where the connecting hole 20 is located abuts against the limiting member 33 accommodated therein so that the limiting member 33 is accommodated in a predetermined position in a predetermined space 40 between the inner surface of the cavity 10 where the connecting hole 20 is located and the tooth surface 50 of the tooth covered by the cavity 10. The limiting member 33 includes a guide portion 333 and a supporting portion 334 which are sequentially connected, and the guide portion 333 is connected to the connecting portion 30; the guide portion 333 is arranged at a preset angle α with the connecting portion 30, and the guide portion 333 cooperates with the connecting hole 20 to guide the limiting member 33 to gather inward, wherein the preset angle α is an acute angle between 5 and 80 degrees, and can be between 10 and 60 degrees in actual applications, or can be 20 or 30 degrees; specifically, because the outer contour dimension of the guide portion 333 away from the supporting portion 334 is less than The connecting hole 20 has an aperture size L, and the portion of the guide portion 333 away from the abutting portion 334 is easily inserted into the connecting hole 20 via the insertion direction Y. Through the guidance of the guide portion 333, during the gradual insertion of the limiting member 33, the portion of the guide portion 333 near the abutting portion 334 is elastically compressed and gathered inwardly, that is, gathered toward the connecting portion 30, so as to pass through the connecting hole 20. When the limiting member 33 is accommodated in the predetermined space 40, the abutting portion 334 abuts against the inner surface of the cavity 10 to limit the movement of the connecting portion 30 along the distal tooth direction.

[0053] It can be understood that the above-mentioned resistance means that the limit member 33 cannot fall out of the connecting hole 20, and does not mean a completely seamless fit and resistance. The outer contour of the connecting portion 30 and the inner contour of the connecting hole 20 are not completely seamless fit. The present application is designed in this way, so that after the snoring stopper 100 is installed, the connecting portion 30 can rotate in the connecting hole 20, so as to realize the movably connecting the connecting rod 3 to the first shell-shaped dental appliance 1 and the second shell-shaped dental appliance 2, so that the patient can open and close his mouth freely while being able to stop snoring.

[0054] Further explanation, in this embodiment, there is a gap 34 between at least the portion of the guide portion 333 away from the insertion end and the connecting portion 30 to provide space for the limiter 33 to gather toward the connecting portion 30. Specifically, the end of the gap 34 away from the connection between the guide portion 333 and the connecting portion 30 is an open structure. It is further defined that there is a gap 34 between at least the portion of the guide portion 333 away from the insertion end and the connecting portion 30 to achieve the inward gathering movement of the guide portion 333. In practical applications, the gap 34 can be achieved by a groove, such as a V-shaped groove.

[0055] To further explain, a surface of the guide portion 333 away from the connecting portion 30 is a guide surface 330 , and the guide surface 330 may be a plane or a rotational surface, and other forms of surfaces may also be used in actual applications, which is not limited here.

[0056] In another embodiment, see Figure 12 to Figure 14 As shown, compared with the previous embodiment ( Figures 6 to 10 The embodiment shown in the figure is different in that the specific structure of the limiting member 33 is different. In the present embodiment, the limiting member 33 includes a guide portion 333, a second abutting portion 335 and a first abutting portion 336 which are arranged in sequence, and the guide portion 333 is connected to the connecting portion 30; the guide portion 333 and the connecting portion 30 are arranged at a preset angle γ, and cooperate with the connecting hole 20 to guide the guide portion 333 to gather inwardly, and the preset angle γ is an acute angle. Similarly, the range of the angle γ is between 5 degrees and 80 degrees, and in actual application it can be between 10 degrees and 60 degrees, or 20 degrees, 30 degrees, etc.; after wearing the anti-snoring device, at least the first abutting portion 336 of the limiting member 33 abuts against the inner surface of the cavity 10 where the connecting hole 20 is located, so as to limit the movement of the connecting portion 30 in the distal direction; Fig.13 As shown, when the stopper 33 is accommodated in the predetermined space 40, the first abutting portion 336 abuts against the inner surface of the cavity 10 where the connecting hole 20 is located. Preferably, this embodiment can be combined with the technical solution that the buccal side of the shell-shaped dental instrument is raised along the distal tooth direction to form a cavitation boss 60, such as Fig.14 As shown, when the limiting member 33 is accommodated in the accommodating cavity 61, the first abutting portion 336 abuts against the first inner surface 101 of the accommodating cavity 61 to limit the movement of the connecting portion 30 in the distal tooth direction, and the second abutting portion 335 abuts against the second inner surface 102 of the accommodating cavity 61 to limit the movement of the connecting portion 30 in the first direction Z, which is different from the distal tooth direction. It is further defined that the angle β between the guiding portion 333 and the second abutting portion 335 is between 100 degrees and 180 degrees, and in practical applications, it can be between 110 degrees and 160 degrees, or can be 120 degrees, 150 degrees, etc.

[0057] In another embodiment, see Fig.15 and Fig.16 As shown, the stopper 33 is formed by plastic deformation of a portion of the connecting portion 30 located on the inner surface of the cavity 10 where the connecting hole 20 is located. In this embodiment, the stopper 33 is formed by deformation of a portion of the connecting portion 30. Specifically, after the connecting portion 30 is inserted into the connecting hole 20 along the insertion direction Y, a portion located on one side of the inner surface of the cavity 10 where the connecting hole 20 is located undergoes plastic deformation under the action of an external force in a direction opposite to the insertion direction Y, forming the stopper 33 as shown in FIG. Fig.16 The limit member 33 structure shown in the figure has an outer wheel width dimension greater than the aperture dimension L of the connecting hole 20 after being formed, and when the connecting portion 30 is subjected to a force in the distal tooth direction, the limit member 33 can abut against the inner surface of the cavity 10 where the connecting hole 20 is located, thereby limiting the movement of the connecting portion 30 in the distal tooth direction.

[0058] Further explanation, the limiter 33 is a columnar structure made of soft plastic. Before being inserted into the connecting hole 20 and without being acted by an external force in the opposite direction to the insertion direction Y, the limiter 33 can be consistent with the structure of the connecting portion 30. Further, it can also be a part of the connecting portion 30, such as a columnar structure, but the material of the connecting portion 30 that does not pass through the connecting hole 20 is inconsistent. It can be understood that the part of the connecting portion 30 accommodated in the connecting hole 20 needs to have a certain mechanical strength, so that after the connecting rod 3 connects the first shell-shaped dental device 1 and the second shell-shaped dental device 2, the mandible can be stably maintained in a position that can open the airway to suppress snoring; and the part that passes through the connecting hole 20 and is located on the inner surface of the cavity 10 where the connecting hole 20 is located can undergo plastic deformation to form the limiter 33, which is used to limit the movement of the connecting portion 30 along the distal tooth direction.

[0059] In some embodiments, see Fig.17 and Fig.18As shown, in order to make the limiting effect of the limiting member 33 more reliable, especially when the limiting member 33 is formed by plastic deformation of a portion of the connecting portion 30 located on the inner surface of the cavity 10 where the connecting hole 20 is located, the snoring stopper 100 described in the present application may also include an annular gasket 35 sleeved on the outer periphery of the connecting portion 30. In order not to affect the movable connection of the connecting portion 30, the inner contour shape of the annular gasket 35 may match the outer contour shape of the connecting portion 30, that is, the aperture size of the inner hole of the annular gasket 35 may be slightly larger than the outer contour size of the connecting portion 30. In order to cooperate with the limiting member 33 to achieve common limiting so as to limit the movement of the connecting portion 30 in the distal tooth direction, the outer diameter size L4 of the annular gasket 35 will be designed to be larger than the aperture size L of the connecting hole 20, and the upper surface and the lower surface of the annular gasket 35 are respectively against the inner surface of the cavity 10 and the surface on the distal tooth side of the limiting member 33.

[0060] In some embodiments, in order to prevent the limiting member 33 located on the tooth-proximal side of the cavity 10 where the connecting hole 20 is located from directly abutting against the patient's tooth surface 50, the present application designs a predetermined space 40 between the inner surface of the cavity 10 where the connecting hole 20 is located and the tooth surface 50 of the tooth accommodated in the cavity 10, for accommodating the limiting member 33, so as to avoid the discomfort caused to the patient by the limiting member 33 abutting against the patient's tooth surface 50, and also to avoid applying unexpected force to the patient's teeth, thereby causing unexpected movement of the teeth. The predetermined space 40 can be enlarged when designing a digital dental model, and the digital dental model of the tooth corresponding to the connecting hole 20 is set, so as to make the connecting hole 20 at the corresponding position on the buccal side of the shell-shaped dental instrument to be manufactured. It can also be as follows Fig.19 and Fig. 20 As shown, the design and manufacture of the predetermined space 40 can be as follows: the buccal surface of the first shell-shaped dental appliance 1 and the second shell-shaped dental appliance 2 protrudes toward the distal tooth to form a cavitation boss 60, and then the connecting hole 20 is arranged on the side wall of the cavitation boss 60 in the distal tooth direction. At this time, the accommodating cavity inside the cavitation boss 60 can be used to accommodate the limiting member 33. After the limiting member 33 is accommodated in the accommodating cavity, as shown in FIG. Fig.11 and Fig.14 shown.

[0061] Please see Fig.21As shown, the present application further provides an anti-snoring device system 1000, which includes at least two anti-snoring devices, namely a first anti-snoring device 300 and a second anti-snoring device 400. The two anti-snoring devices can be the anti-snoring device 100 described in any of the above embodiments, with the difference that the two anti-snoring devices respectively keep the patient's lower jaw at different positions capable of opening the airway, for example, the first anti-snoring device 300 can keep the patient's lower jaw at a first predetermined position capable of opening the airway, and the second anti-snoring device 400 is used to keep the patient's lower jaw at a second predetermined position capable of opening the airway in a subsequent stage.

[0062] It is further explained that the distance D2 of the mandibular sagittal X moving forward corresponding to the second predetermined position is greater than the distance D1 of the mandibular sagittal X moving forward corresponding to the first predetermined position. According to clinical experience, in the process of suppressing snoring, the patient guides the mandibular sagittal X forward to the normal occlusal position of the patient to a position range of 3mm beyond the normal occlusal position, and a good treatment effect will be obtained, for example, the snoring effect and the comfort of the patient can be taken into account. After a stage of treatment, if the distance of guiding the mandibular sagittal X forward in the current treatment stage is maintained, because the muscles around the patient's upper respiratory tract have adapted to the current amount of mandibular sagittal forward guidance, when the patient is asleep, the tension of the muscles around the upper respiratory tract is insufficient, and the airway cannot be kept open during the inhalation phase of the respiratory cycle, which will lead to a significant reduction in the therapeutic effect of snoring. At this time, the clinician can guide the patient to increase the distance of guiding the mandibular sagittal X forward, for example, the mandibular sagittal X can be guided forward to a position 5mm beyond the normal occlusal position, so as to obtain a better therapeutic effect of suppressing snoring. The anti-snoring system 1000 is based on the above-mentioned anti-snoring treatment plan, and provides the patient with an easy-to-operate anti-snoring system 1000 that is convenient and reliable.

[0063] It should be noted that the above embodiments can be freely combined as needed to form different new implementation plans without causing any contradiction. The implementation plans formed after such combination are all within the scope of protection of this application. In order to save the length of the application text, they will not be repeated here.

[0064] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the creative principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present application.

[0065] Similarly, the above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
