Description

Technical Field

[0001] This utility model relates to the field of anti-snoring braces, and in particular to an adjustable mandibular advancement anti-snoring brace. Background Technology

[0002] The mandibular advancement brace is an oral appliance used to treat snoring and mild to moderate obstructive sleep apnea-hypopnea syndrome (OSAHS). It primarily works by physically moving the mandible forward, thereby expanding the upper airway space and reducing upper airway collapse and obstruction during sleep, thus alleviating or eliminating snoring symptoms and improving sleep breathing.

[0003] Patients with sleep apnea syndrome usually need to wear a mandibular advancement brace to improve their breathing during sleep. A traditional mandibular advancement brace consists of two parts: an upper brace and a lower brace. The bottom of the upper brace has a limiting post, and the top of the lower brace has a groove. The installation and fixation are completed by the friction or interference fit between the limiting post and the groove. Then it can be placed into the user's mouth for use. At the same time, there are multiple sets of grooves, so that the horizontal distance between the upper and lower braces can be adjusted to accommodate users with different snoring sounds.

[0004] However, when adjustments are needed, the user pulls the upper and lower braces apart. To ensure a stable connection between the upper and lower braces during use and prevent easy separation, the friction or interference fit is usually set quite high. This results in a significant frictional force needing to be overcome when pulling the braces apart. This large pulling force, exceeding the material's tolerance limit, can easily cause deformation or even breakage of the limiting post. A damaged post will become stuck in the groove, leaving the upper and lower braces without a fixed structure, thus rendering them unusable. Therefore, an adjustable mandibular advancement anti-snoring brace is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable mandibular advancement anti-snoring brace, which aims to improve the problem that in the prior art, the upper and lower braces achieve a fixing effect through friction or interference fit, which causes the fixing components to be damaged during subsequent adjustments and thus cannot be used normally.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable mandibular advancement anti-snoring brace, including an upper brace, wherein a connecting mechanism is provided at the bottom of the upper brace;

[0007] The connecting mechanism includes a limiting post fixedly connected to the bottom of the upper dental brace, the outer arc surface of the limiting post contacting the lower dental brace, the inner wall of the lower dental brace being elastically connected to a connecting plate via a connecting spring, a limiting block being fixedly connected to the top of the connecting plate, a contact element being provided on the side of the connecting plate away from the connecting spring, and an adjustment mechanism being provided at the bottom of the upper dental brace.

[0008] As a further description of the above technical solution:

[0009] The contact element includes a pressing plate fixedly connected to the outer wall of the connecting plate, the outer wall of the pressing plate penetrating and slidably connected to the inner wall of the lower dental brace.

[0010] As a further description of the above technical solution:

[0011] The top of the lower dental brace has a circular groove that matches the limiting post. The outer wall of the limiting block is slidably connected to the inner wall of the circular groove, and the outer wall of the connecting plate is slidably connected to the inner wall of the lower dental brace.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-2 One embodiment of this utility model is an adjustable mandibular advancement anti-snoring brace, including an upper brace 1, with a connecting mechanism 3 at the bottom of the upper brace 1; the connecting mechanism 3 is provided to prevent damage when the anti-snoring brace is disassembled as a whole.

[0035] Reference Figures 2-4 The connecting mechanism 3 includes a limiting post 302 fixedly connected to the bottom of the upper dental bracket 1. The outer arc surface of the limiting post 302 contacts the lower dental bracket 2. There are two sets of limiting posts 302, and the splicing between the upper dental bracket 1 and the lower dental bracket 2 completes the anti-snoring operation. The inner wall of the lower dental bracket 2 is elastically connected to a connecting plate 303 through a connecting spring 305. The top of the connecting plate 303 is fixedly connected to a limiting block 304. The elasticity of the connecting spring 305 enables the limiting block 304 to have the functions of limiting and resetting. There are multiple sets of limiting blocks 304. A rubber mold made of teeth can be placed on the inner surface of the upper dental bracket 1 and the lower dental bracket 2. This is prior art and will not be explained in detail here. A contact element is provided on the side of the connecting plate 303 away from the connecting spring 305. There are two sets of contact elements to facilitate manual pressing of the connecting spring 305. An adjustment mechanism 4 is provided at the bottom of the upper dental bracket 1. The tongue plate can be adjusted by the setting of the adjustment mechanism 4.

[0036] Reference Figures 3-5The contact element includes a pressing plate 301 fixedly connected to the outer wall of the connecting plate 303. The outer wall of the pressing plate 301 penetrates and slidably connects to the inner wall of the lower dental brace 2. When it is necessary to disassemble the upper dental brace 1 and the lower dental brace 2, a circular groove adapted to the limiting post 302 is opened on the top of the lower dental brace 2. Multiple sets of circular grooves are provided to facilitate the adjustment of the horizontal distance between the upper dental brace 1 and the lower dental brace 2. The outer wall of the limiting block 304 penetrates and slidably connects to the inner wall of the circular groove. The through-hole setting facilitates the limiting block 304 to be located in the circular groove and exposed, thereby facilitating the fixation of the limiting post 302. The outer wall of the connecting plate 303 is slidably connected to the inner wall of the lower dental brace 2. The sliding setting avoids movement interference. The outer arc of the limiting post 302... The upper brace 1 has a square groove 306. The inclined surface of the limiting block 304 is inserted into the inner wall of the square groove 306. The two are inserted to prevent the upper brace 1 from being pulled out, thereby fixing the upper brace 1. The inclined surface is designed to facilitate the bottom of the limiting post 302 to contact and squeeze the inclined surface when installing the upper brace 1, thereby causing the limiting block 304 to move. The outer wall of the lower brace 2 has a square groove. The end of the pressing plate 301 away from the limiting block 304 is located inside the square groove. The square groove is designed to facilitate the manual removal of the upper brace 1 by pinching the two sets of pressing plates 301 in the middle. When it is located inside the square groove, the user's internal oral epithelial tissue will not come into contact with the gap of the pressing plate 301, thereby preventing the gap from pinching the user's oral cavity.

[0037] Reference Figures 2-3 and Figure 6 The adjustment mechanism 4 includes a support column 403. The bottom of the upper dental brace 1 has a connecting groove, and a tongue depressor 401 contacts the inside of the connecting groove. The connecting groove allows the tongue depressor 401 to be adjusted horizontally. The outer wall of the tongue depressor 401 has a circular hole 402 that matches the support column 403. The outer arc surface of the support column 403 contacts the inner surface of the circular hole 402, and this contact secures the tongue depressor 401. Multiple sets of circular holes 402 are provided, facilitating manual adjustment of the horizontal distance of the tongue depressor 401. The top of the lower dental brace 2 has a positioning groove 404. The outer arc surface of the support column 403 is inserted into the inner surface of the positioning groove 404. The diameter of the positioning groove 404 is the same as the inner surface diameter of the circular hole 402. The top of the support column 403 is fixedly connected to the inside of the connecting groove, providing support for the support column 403. The diameter of the support column 403 is smaller than that of the limiting column 302. Figure 6 As shown, after the limiting post 302 is installed, the support post 403 can be located inside the circular groove.

[0038] Working principle: When the upper brace 1 and lower brace 2 are joined, the limiting post 302 is inserted into the circular groove at the top of the lower brace 2. The square groove 306 on the outer arc surface of the limiting post 302 is aligned with the limiting block 304 in the circular groove. Since the limiting block 304 is connected to the connecting plate 303 through the connecting spring 305, when the limiting post 302 is inserted, its bottom presses against the inclined surface of the limiting block 304, pushing the limiting block 304 to move inward against the elastic force of the connecting spring 305 to compress the spring. When the square groove 306 is aligned with the limiting block 304, the connecting spring 305 returns to its original position, and the limiting block 304 is inserted into the square groove 306, forming a locking connection to prevent the upper brace 1 from being pulled outward. When it is necessary to separate the entire brace, the user can press and pinch the square groove on the outer wall of the lower brace 2 to actuate the pressing plates 301 on both sides. The pressing plate 301 moves the connecting plate 303 inward, compressing the connecting spring 305 and causing the limiting block 304 to disengage from the square groove 306 of the limiting post 302. At this time, the limiting post 302 can be easily pulled out of the round groove, avoiding damage to the limiting post 302 caused by forced pulling in traditional interference fits. The top of the lower aligner 2 has multiple sets of round grooves, corresponding to different forward movement distances. By changing the position of the round groove and inserting the limiting post 302, the horizontal distance between the aligners can be adjusted to suit the patient's mandibular forward movement needs, and the insertion structure of the limiting block 304 and the square groove 306 ensures a stable connection after adjustment.

[0039] The tongue depressor 401 is fitted onto the support post 403 through a round hole 402 on its outer wall. The top of the support post 403 is fixed in the connecting groove at the bottom of the upper brace 1, and the bottom is inserted into the positioning groove 404 at the top of the lower brace 2, forming an upper and lower support. At this time, the tongue depressor 401 is confined in the connecting groove and cannot move laterally, thus stably supporting the tongue. If it is necessary to adjust the horizontal position of the tongue depressor 401 to adapt to different tongue sizes or treatment stages, the tongue depressor 401 can be removed, and then different positions of the round hole 402 can be selected to match the support post 403. The spacing of the round holes 402 is preset to different adjustment levels, ensuring that after adjustment, the tongue depressor 401 is still fixed to the positioning groove 404 through the support post 403, maintaining the support effect on the tongue.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
