Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically an integrated early correction device for children's mouth breathing and maxillary stenosis. Background Technology

[0002] In early pediatric orthodontic practice, mouth breathing and maxillary stenosis often create a vicious cycle. Mouth breathing can lead to maxillary arch stenosis, high palatal arch, crowded teeth, mandibular retrusion, and abnormal facial development; while maxillary stenosis can reduce the space at the base of the nasal cavity, further reducing nasal ventilation efficiency and exacerbating mouth breathing habits.

[0003] Currently available orthodontic appliances for treating the above-mentioned problems have significant shortcomings: 1. Traditional maxillary expanders can only widen the dental arch, without mouth breathing blockage or nasal breathing induction functions; mouth breathing appliances can only correct breathing habits, without bony expansion function, and children need to wear multiple sets of devices, resulting in poor compliance and cumbersome wearing. 2. Most existing mouth breathing blocking devices are fixed structures, which cannot adjust the ventilation opening according to the treatment process. In the early stage, they are prone to causing excessively high nasal ventilation pressure and discomfort to children. In the later stage, they cannot be gradually adapted, resulting in low clinical standardization. 3. Most devices cannot make real-time and intuitive judgments on nasal breathing status. Relying solely on parental observation and doctors' subjective assessment makes it difficult to quantify efficacy and support scientific data collection and research projects.

[0004] Therefore, developing an early childhood orthodontic device that integrates maxillary arch expansion, graded nasal breathing induction, passive airflow visualization monitoring, comfortable to wear, removable, and adaptable in stages has become a pressing technical problem to be solved in clinical practice. Summary of the Invention

[0005] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides an integrated early correction device for children's mouth breathing and maxillary stenosis, which effectively solves the problem of the single function of existing correction devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated early correction device for oral breathing and maxillary stenosis in children, comprising a correction device body, wherein the correction device body is composed of a maxillary arch expansion component, a graded adjustable nasal ventilation induction baffle component, and a passive airflow visualization nasal breathing monitoring component. The maxillary arch expansion component is installed inside the oral cavity at the maxillary position and engages with the posterior molars.

The graded adjustable nasal ventilation induction baffle assembly consists of a connecting sleeve, a support arm, a telescopic sleeve, and a baffle body. One end of the connecting sleeve is fixedly connected to the maxillary arch expander assembly, and one end of the support arm is fixedly connected to the connecting sleeve. The telescopic sleeve is fitted onto the end of the support arm away from the connecting sleeve, and the telescopic sleeve and the support arm are engaged through built-in blocks and slots. The passive airflow visualization nasal breathing monitoring component consists of an adjustable bracket, a transparent resin guide sleeve, and two visualization monitoring units. The adjustable bracket is connected to a graded adjustable nasal ventilation induction baffle assembly, and the transparent resin guide sleeve is fixedly connected to the adjustable bracket. The transparent resin guide sleeve has two guide holes inside, and the two visualization monitoring units are installed inside the two guide holes respectively.

[0007] Preferably, the integrated palatal base is composed of a base one, a base two, a limiting rod one, a limiting rod two, a double-ended screw, and an adjusting sleeve. Base one and base two are slidably sleeved on both ends of the limiting rod one and the limiting rod two. The two ends of the double-ended screw pass through the middle positions of base one and base two respectively and are threadedly connected to them. The adjusting sleeve is sleeved on the middle position of the double-ended screw and is fixedly connected to it. The arc-shaped outer surface of the adjusting sleeve has several circular adjusting grooves. Maxillary expansion unit one and maxillary expansion unit two are both composed of a dental sleeve one, a dental sleeve two, a connecting arm, an elastic support arm one, and an elastic support arm two. Dental sleeve one, dental sleeve two, connecting arm, elastic support arm one, and elastic support arm two are integrally molded structures. Elastic support arm one and elastic support arm two are fixedly connected to base one and base two.

[0008] Preferably, both sides of one end of the support arm are welded with cross arms, and flexible built-in sealing plate one and flexible built-in sealing plate two are respectively snapped onto the two cross arms. The adjacent ends of flexible built-in sealing plate one and flexible built-in sealing plate two are attached and sleeved on the support arm. Flexible built-in sealing plate one and flexible built-in sealing plate two are each composed of a main body, a movable plate, a positioning rod, a universal ball sleeve, a universal ball head, and a synchronous traction rod. The main body is fixedly connected to the cross arms, one end of the positioning rod slides through the cross arms, and the movable plate is fixedly connected to the positioning rod. The other end is attached to the main body. The universal ball sleeve is fixedly connected to one end of the side of the movable plate. The universal ball head is rotatably connected to the inside of the universal ball sleeve. The synchronous traction rod is fixedly connected between the universal ball head and the tooth sleeve. Several vent holes are provided on the main body. Several vent holes are provided on the movable plate that match the vent holes. The end of the movable plate away from the cross arm has a rounded corner structure. Flat brackets are welded on both sides of one end of the telescopic sleeve. A flexible fitting sealing plate that matches the vent hole is fixedly installed at one end of the flat bracket.

[0009] Preferably, the baffle body is composed of a rigid arc-shaped baffle, a flexible gasket, an inner support rod, a slide block, and a locking bolt. The flexible gasket is fixedly connected to the inner surface of the rigid arc-shaped baffle, the inner support rod is fixedly connected to the inside of the rigid arc-shaped baffle and is fixedly connected to the telescopic sleeve, the slide block is fixedly connected to one end of the inner support rod, and the locking bolt passes through the slide block and is threaded to it. The bottom end of the adjustable bracket is provided with a limiting groove that slides with the slide block. The visual monitoring unit is composed of a rigid limiting frame, a T-shaped support frame, and a flexible swing bar. The rigid limiting frame and the T-shaped support frame are both fixedly connected to the inside of the transparent resin guide sleeve. The flexible swing bar is fixedly connected to one end of the T-shaped support frame and fits against the rigid limiting frame. The visual monitoring unit realizes real-time and visual feedback of nasal breathing status through airflow drive.

[0010] Compared with the prior art, the beneficial effects of the present invention are: In practice, by integrating maxillary arch expansion, graded adjustable nasal ventilation induction, and passive airflow visualization nasal breathing monitoring into one device, a single device can simultaneously complete maxillary bony arch expansion and oral breathing muscle function correction, breaking the vicious cycle of "mouth breathing - maxillary stenosis - insufficient nasal ventilation", improving treatment efficiency and shortening the treatment course. Through the interlocking adjustment of the support arm and telescopic sleeve, and the cooperation of the flexible sealing plate and the ventilation hole, the three-stage adjustable ventilation can be achieved: strong mouth breathing blockage, nasal breathing adaptation training, and habit maintenance and consolidation. The ventilation opening can be gradually adjusted according to the improvement of the child's nasal ventilation, resulting in higher comfort and stronger clinical operability. It adopts a transparent resin guide sleeve and flexible swing strip structure, which does not require power supply or electronic components. It can drive the swing strip through airflow to display the nasal breathing status in real time, which is convenient for doctors to follow up and evaluate, and for parents to observe and record. It provides objective data support for clinical efficacy evaluation, scientific research papers and research projects. Stable retention is achieved through an integrated palatal base and posterior braces, which are non-adhesive and removable. A flexible pad is placed on the inner side of the baffle, and the sealing plate is made of flexible material with smooth edges that do not compress the lips, significantly improving children's compliance. The palatal base uses a double-ended screw and limiting rod structure, ensuring precise arch expansion adjustment, symmetrical left and right sides, and no tilting. The baffle and bracket are fixed by slides and locking bolts, resulting in a strong overall connection that is not easily deformed, meeting the needs of long-term early orthodontic use. This invention integrates maxillary arch expansion, nasal breathing induction, and visual monitoring of airflow, enabling simultaneous structural correction and respiratory function training. This can improve the early intervention effect and treatment compliance of children with mouth breathing. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0014] Example 1, by Figure 1 , Figure 2 , Figure 4 and Figure 5 The present invention provides an integrated early correction device for oral breathing and maxillary stenosis in children, comprising a correction device body 1, which consists of a maxillary arch expansion component 2, a graded adjustable nasal ventilation induction baffle component 3, and a passive airflow visualization nasal breathing monitoring component 4. The maxillary arch expansion component 2 is installed inside the oral cavity at the maxillary position and engages with the posterior molars. The graded adjustable nasal ventilation induction baffle component 3 is installed at one end of the maxillary arch expansion component 2 and extends to the outside of the oral cavity. The passive airflow visualization nasal breathing monitoring component 4 is installed at one end of the top of the graded adjustable nasal ventilation induction baffle component 3. The maxillary arch expansion component 2 progressively widens the maxillary dental arch and palatal midline, increasing the bony space at the bottom of the nasal cavity, improving nasal airway anatomically, and breaking the vicious cycle of mouth breathing and maxillary stenosis; the graded adjustable nasal ventilation induction baffle component 3 is adjusted in stages according to "forced blocking - adaptation training - habit maintenance" to adapt to the child's growth and development and treatment progress, improving treatment compliance; the passive airflow visualization nasal breathing monitoring component 4 uses the natural airflow of nasal breathing to drive the visualization indicator structure, requiring no power supply or sensors, intuitively and objectively reflecting the recovery status of nasal breathing, facilitating follow-up assessment by doctors.

[0015] Example 2, based on Example 1, is... Figure 2 and Figure 3As shown, the maxillary expansion assembly 2 consists of an integrated palatal base 5, a first maxillary expansion unit 6, and a second maxillary expansion unit 7. The first maxillary expansion unit 6 and the second maxillary expansion unit 7 are symmetrically installed on both sides of the integrated palatal base 5. The integrated palatal base 5 consists of a first base 16, a second base 17, a first limiting rod 18, a second limiting rod 19, a double-ended screw 20, and an adjusting sleeve 21. The first base 16 and the second base 17 are slidably sleeved on both ends of the first limiting rod 18 and the second limiting rod 19. The two ends of the double-ended screw 20 pass through the middle positions of the first base 16 and the second base 17, respectively, and are connected to them. The threaded connection is provided. The adjusting sleeve 21 is fitted in the middle position of the double-ended screw 20 and fixedly connected to it. The arc-shaped outer surface of the adjusting sleeve 21 is provided with several circular adjusting slots 22. The maxillary expansion unit 1 6 and the maxillary expansion unit 2 7 are both composed of dental sleeve 1 23, dental sleeve 2 24, connecting arm 25, elastic support arm 1 26 and elastic support arm 2 27. Dental sleeve 1 23, dental sleeve 2 24, connecting arm 25, elastic support arm 1 26 and elastic support arm 2 27 are integrally formed structures. Elastic support arm 1 26 and elastic support arm 2 27 are fixedly connected to base 1 16 and base 2 17. The maxillary expansion component 2 consists of an integrated palatal base 5 that supports the maxillary expansion unit 1 6 and the maxillary expansion unit 2 7. The maxillary expansion unit 1 6 and the maxillary expansion unit 2 7 are used to widen the maxillary dental arch and the mid-palatal suture, increase the bony space at the bottom of the nasal cavity, and improve nasal airflow. During the orthodontic treatment, progressive adjustments can be made. During adjustment, medical staff use instruments such as an L-shaped wrench to insert into the circular adjustment slot 22, causing the adjustment sleeve 21 to rotate. The adjustment sleeve 21 then rotates the double-ended screw 20. The double-headed screw 20 drives the base 16 and base 27 to adjust synchronously. The limiting rod 18 and limiting rod 29 limit and guide the base 16 and base 27. The maxillary arch expansion unit 16 and maxillary arch expansion unit 27 are put on the posterior molars. The dental sleeve 1 23 and dental sleeve 2 24 are put on the teeth to form a support. The elastic support arm 1 26 and elastic support arm 2 27 can form elastic support. With long-term wear, it can effectively widen the maxillary dental arch and the mid-palatal suture.

[0016] Example 3, based on Example 1, is... Figure 2 , Figure 4 , Figure 5 and Figure 8The adjustable nasal ventilation induction baffle assembly 3 is composed of a connecting sleeve 8, a support arm 9, a telescopic sleeve 10, and a baffle body 11. One end of the connecting sleeve 8 is fixedly connected to the maxillary arch expander assembly 2, and one end of the support arm 9 is fixedly connected to the connecting sleeve 8. The telescopic sleeve 10 is fitted onto the end of the support arm 9 away from the connecting sleeve 8. The telescopic sleeve 10 and the support arm 9 are engaged through built-in locking blocks and slots. Horizontal arms 28 are welded to both sides of one end of the support arm 9. Flexible internal sealing plate 1 29 and flexible internal sealing plate 2 30 are respectively engaged on the two horizontal arms 28. The adjacent ends of flexible internal sealing plate 1 29 and flexible internal sealing plate 2 30 are fitted and sleeved onto the support arm 9. Both flexible internal sealing plate 1 29 and flexible internal sealing plate 2 30 are composed of a main body 43, a movable plate 44, a positioning rod 45, a universal ball sleeve 46, and a universal joint. The system consists of a ball head 47 and a synchronous traction rod 48. The main body 43 is fixedly connected to the cross arm 28. One end of the positioning rod 45 slides through the cross arm 28. The movable plate 44 is fixedly connected to the other end of the positioning rod 45 and fits against the main body 43. The universal ball sleeve 46 is fixedly connected to one end of the side of the movable plate 44. The universal ball head 47 is rotatably connected to the inside of the universal ball sleeve 46. The synchronous traction rod 48 is fixedly connected between the universal ball head 47 and the toothed sleeve 24. The main body 43 has several vent holes 49. The movable plate 44 has several vent holes 50 that match the vent holes 49. The end of the movable plate 44 away from the cross arm 28 has a rounded corner structure. Flat brackets 32 are welded to both sides of one end of the telescopic sleeve 10. A flexible sealing plate 33 that matches the vent holes 49 is fixedly installed at one end of the flat bracket 32. The adjustable nasal ventilation induction baffle assembly 3 has 3-5 adjustable positions, corresponding to the three treatment stages: initial forced mouth breathing intervention, intermediate nasal breathing adaptation, and later maintenance and consolidation (divided into two consolidation methods: fully open adaptive nasal breathing and fully closed forced nasal breathing). The telescopic sleeve 10 can be adjusted in position with the support arm 9 to extend or shorten, thereby adjusting the position of the baffle body 11. In the initial stage of treatment, the baffle body 11 is completely fitted to the lips to achieve full occlusion. The flexible internal occlusion plate 1 29 and the flexible internal occlusion plate 2 30 are located inside the oral cavity to achieve secondary occlusion. At this time, the flexible fitting occlusion plate 33 and the flexible internal occlusion plate 30 are in close contact with the lips. Flexible built-in sealing plate 29 and flexible built-in sealing plate 30 are fitted together to block the vent 49, forcibly blocking airflow in the oral cavity and inducing nasal breathing. In the middle stage of treatment, the telescopic sleeve 10 is stretched outward a certain distance, so that the baffle body 11 has a certain gap with the lips. At this time, the flat support 32 moves with the telescopic sleeve 10, so that the flexible fitting sealing plate 33 separates from the flexible built-in sealing plate 29 and flexible built-in sealing plate 30, and the vent 49 is also in an open state, training the nasal respiratory muscles to adapt. In the later stage of treatment, the baffle body 11 is finely adjusted to solidify the nasal breathing habit. This method is a fully open adaptive nasal breathing. In the later stages of orthodontic treatment, in addition to opening vents 1 (49) and vent 2 (50) to solidify nasal breathing habits, complete closure can also be achieved to increase the intensity of nasal breathing. In the later stages of orthodontic treatment, the expansion degree of the expander increases, and the distance between the two braces 2 (24) increases synchronously. At this time, braces 2 (24) drive the synchronous traction rod 48 to move, the synchronous traction rod 48 drives the universal ball head 47 to move, and the universal ball head 47 drives the universal ball sleeve 46 and the movable plate 44 to move synchronously. The setting of the universal ball sleeve 46 and the universal ball head 47 can improve the angle adaptability. Vent 2 (50) on the movable plate 44 and vent 1 (49) on the main plate 43 are misaligned, transitioning from the initial completely overlapping state to the later completely closed state, increasing the resistance level. Thus, when forced nasal breathing occurs in the later stages, it can further block the airflow through the mouth. This method is called fully closed forced nasal breathing.

[0017] Example 4, based on Example 1, by Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The passive airflow visualization nasal breathing monitoring component 4 consists of an adjustable bracket 12, a transparent resin guide sleeve 13, and two visualization monitoring units 14. The adjustable bracket 12 is connected to the graded adjustable nasal ventilation induction baffle assembly 3. The transparent resin guide sleeve 13 is fixedly connected to the adjustable bracket 12. Two guide holes 15 are opened inside the transparent resin guide sleeve 13, and the two visualization monitoring units 14 are respectively installed inside the two guide holes 15. The baffle body 11 consists of a rigid arc-shaped baffle 34, a flexible gasket 35, an inner support rod 36, a slide 37, and a locking bolt 38. The flexible gasket 35 is fixedly connected to the inner surface of the rigid arc-shaped baffle 34, and the inner support rod 36 is fixedly connected to the inside of the rigid arc-shaped baffle 34. The slide block 37 is fixedly connected to one end of the inner support rod 36 and is fixedly connected to the telescopic sleeve 10. The locking bolt 38 passes through the slide block 37 and is threaded to it. The bottom end of the adjustable bracket 12 is provided with a limiting groove 39 that is slidably connected to the slide block 37. The visual monitoring unit 14 is composed of a rigid limiting frame 40, a T-shaped support frame 41 and a flexible swing bar 42. The rigid limiting frame 40 and the T-shaped support frame 41 are both fixedly connected to the inside of the transparent resin guide sleeve 13. The flexible swing bar 42 is fixedly connected to one end of the T-shaped support frame 41 and fits against the rigid limiting frame 40. The visual monitoring unit 14 realizes real-time and visual feedback of nasal breathing status through airflow drive. The transparent resin guide sleeve 13 is used to guide nasal breathing. The visual monitoring unit 14 can intuitively judge the nasal breathing status. After mouth breathing is blocked, during the nasal breathing process, air flows through the guide hole 15 inside the transparent resin guide sleeve 13. At this time, the flexible swing strip 42 will move with the airflow. The swing of the flexible swing strip 42 can be intuitively judged whether nasal breathing is normal. Since this device is mainly worn when sleeping, the flexible swing strip 42 is in a horizontal state and will swing down under the action of gravity. The T-shaped support frame 41 and the rigid limiting frame 40 can play an auxiliary support and limiting role. The flexible pad 35 can have a buffering effect with the lips. In the later stage of treatment, since the position of the baffle body 11 needs to be adjusted, the slide 37 can slide inside the limiting slide groove 39 and be locked and fixed by the locking bolt 38, so that the transparent resin guide sleeve 13 can always fit tightly with the nose.

[0018] By integrating maxillary arch expansion, graded adjustable nasal ventilation induction, and passive airflow visualization nasal breathing monitoring into one device, this system simultaneously completes maxillary skeletal arch expansion and oral breathing muscle function correction, breaking the vicious cycle of "mouth breathing - maxillary stenosis - insufficient nasal ventilation," improving treatment efficiency and shortening the treatment course. Through the interlocking adjustment of the support arm and telescopic sleeve, and the coordination of the flexible sealing plate and ventilation holes, it achieves three adjustable stages: strong mouth breathing blockage, nasal breathing adaptation training, and habit maintenance and consolidation. The ventilation opening can be gradually adjusted according to the child's improvement in nasal ventilation, resulting in higher comfort and stronger clinical operability. Utilizing a transparent resin guide sleeve and flexible swing strip structure, it requires no power supply or electronic components. Airflow drives the swing strip to display the nasal breathing status in real time, facilitating doctor follow-up assessments and parental observation and recording, providing objective data support for clinical efficacy evaluation, research papers, and project research. The palatal base and posterior braces achieve stable retention without adhesion and can be removed and worn independently. A flexible pad is placed on the inner side of the baffle, and the sealing plate is made of flexible material with smooth edges that do not compress the lips, significantly improving children's compliance. The palatal base uses a double-ended screw and limiting rod structure, ensuring precise arch expansion adjustment, bilateral symmetry, and no tilting. The baffle and bracket are fixed by slides and locking bolts, resulting in a strong overall connection that is not easily deformed, meeting the needs of long-term early orthodontic use. It is suitable for children with maxillary stenosis accompanied by mouth breathing, insufficient nasal ventilation, and facial development abnormalities during the mixed dentition and primary dentition stages. It eliminates the need for rotating multiple devices, simplifying clinical operation and follow-up procedures, and possesses both clinical practicality and research value. By systematically integrating maxillary arch expansion, nasal breathing induction, and visual airflow monitoring, it enables simultaneous structural orthodontic treatment and respiratory function training, improving the early intervention effect and treatment compliance in children with mouth breathing.
