Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an occlusal device. Background Technology

[0002] Breathing training is a method to enhance respiratory system function through specific exercises. Its main purpose is to improve respiratory function and increase gas exchange efficiency, with the following key benefits: First, it effectively strengthens lung muscles and improves lung capacity; second, it helps improve blood circulation efficiency, promoting oxygen supply and the removal of metabolic waste; third, for patients with chronic respiratory diseases, breathing training can help stabilize their condition and slow its deterioration; fourth, for athletes, it can further improve endurance and athletic performance, while for the general population, it can enhance physical fitness, improve daily athletic performance, and enhance quality of life.

[0003] However, existing breathing training devices usually include a bite block. The existing bite block has no force-bearing point, which makes it easy to fall out of the mouth during use. In order to improve its stability, the patient needs to apply more force to bite the bite block, but the greater force will deform the bite block, causing it to collapse or even block the airflow, thus affecting the patient's breathing and making it inconvenient to use.

[0037] In this specification, axial direction refers to the direction parallel to the line connecting the distal and proximal centers of the component; radial direction refers to the direction perpendicular to the aforementioned axial direction.

[0038] In one embodiment, the bite device 100 of this utility model includes a body 2 and a bite portion 1 disposed at the proximal end of the body 2, such as... Figures 1 to 11 As shown.

[0039] Preferably, the body 2 is hollow and has a second cavity 25 inside, so that air can circulate inside, making it convenient for the patient to inhale or exhale.

[0040] More preferably, the body 2 is elongated and extends from the proximal end to the distal end.

[0041] It should be noted that the "proximal end" mentioned above refers to the end closer to the operator, and the "distal end" refers to the end farther away from the operator.

[0042] More preferably, the body 2 can be a regular geometric shape, such as a cylinder, cuboid, or other geometric shape, or it can be an irregular geometric shape, without any specific limitation.

[0043] Preferably, the body 2 is made of silicone material, which allows it to withstand temperatures up to 180 degrees Celsius for extended periods and up to 220 degrees Celsius for short periods, meeting the needs of general household disinfection methods without producing harmful substances.

[0044] More preferably, the occlusal part 1 is located at the proximal end of the body 2, which is usually held in the mouth of the patient for convenient use.

[0045] Furthermore, the occlusal portion 1 is flat and adapted to the shape of the patient's mouth so that the patient's mouth can bite the occlusal portion 1. In other embodiments, the occlusal portion 1 may also be other geometric shapes, which are not specifically limited here.

[0046] Furthermore, the interlocking part 1 is fixedly connected to the body 2, such as by bonding or hot-melt fixing, or it can be integrally molded, which not only simplifies the process but also improves the structural stability.

[0047] Furthermore, the bite part 1 is made of silicone material, which allows it to withstand temperatures up to 180 degrees Celsius for extended periods and up to 220 degrees Celsius for short periods, meeting the needs of general household disinfection methods without producing harmful substances.

[0048] It should be noted that the bite part 1 has a first cavity 14 inside, which is connected to the second cavity 25, so that gas can be connected between the first cavity 14 and the second cavity 25.

[0049] In one embodiment, the outer surface of the engagement portion 1 is provided with a plurality of protrusions 12, the plurality of protrusions 12 being arranged in at least two rows, each row of protrusions 12 being arranged in an arc shape, such as... Figures 1 to 11 As shown.

[0050] Preferably, multiple protrusions 12 are provided and distributed on the outer surface of the biting part 1. They can be distributed individually on the upper surface of the biting part 1, or individually on the lower surface of the biting part 1, or simultaneously on the upper and lower surfaces of the biting part 1. No specific limitation is made here. In this embodiment, multiple protrusions 12 are simultaneously distributed on the upper and lower surfaces of the biting part 1.

[0051] More preferably, the protrusion 12 extends outward from the outer surface of the occlusal portion 1, thereby increasing the friction with the patient's teeth and preventing it from falling off during use.

[0052] More preferably, the plurality of protrusions 12 are arranged in at least two rows on the outer surface of the engagement portion 1, such as two, three, or four rows, and the specific number can be set as needed, without being specifically limited here.

[0053] Preferably, in each row of protrusions 12, the protrusions 12 are arranged at intervals, preferably at equal intervals, thereby not only reducing costs, but also significantly increasing the friction with the teeth and improving the stability of use.

[0054] More preferably, each row of protrusions 12 is arranged in an arc shape, with the middle portion protruding towards the body 2, thereby adapting to the tooth shape to increase the friction with the teeth.

[0055] Furthermore, the multiple rows of protrusions 12 are parallel to each other, thereby preventing adjacent rows of protrusions 12 from intersecting and affecting the friction with the teeth.

[0056] Furthermore, multiple rows of protrusions 12 are arranged sequentially and at intervals from the proximal end to the distal end to accommodate different depths of the occlusal portion 1 into the patient's mouth and meet different needs.

[0057] Furthermore, the bump 12 can be hemispherical or other geometric shapes, and users can set it according to their needs. No specific limitations are made here.

[0058] In one embodiment, the plurality of the protrusions 12 are arranged in three rows, such as Figures 1 to 3 and Figure 8 As shown.

[0059] Preferably, the protrusions 12 are arranged in three rows and are spaced apart in the direction from the proximal end to the distal end, which not only reduces the cost, but also adapts to different depths of the occlusal part 1 in the mouth and increases the friction with the teeth.

[0060] More preferably, the lengths of the three rows of protrusions 12 can be the same or different. For example, the length of the middle row of protrusions 12 can be shorter than the lengths of the other two rows of protrusions 12. This not only increases the friction with the teeth but also reduces costs. Users can set this according to their needs, and no specific limitation is made here.

[0061] More preferably, the curvature of the three rows of protrusions 12 can be the same or different, and the user can set it according to his or her needs. No specific limitation is made here.

[0062] In one embodiment, in each row of the bumps 12, the distance between any two adjacent bumps 12 is the same. For example... Figure 3 and Figure 8 As shown.

[0063] Preferably, in each row of protrusions 12, the distance between adjacent protrusions 12 is equal, thereby ensuring a balanced frictional force with the teeth and ensuring stability during use.

[0064] It should be noted that in other embodiments, the distance between adjacent protrusions 12 may be unequal, and the user can set it as needed, without making specific limitations here.

[0065] It should also be noted that the distance between adjacent bumps 12 is the minimum distance between two adjacent bumps 12.

[0066] More preferably, in different rows of bumps 12, the distance between two adjacent bumps 12 can be the same or different. For example, in the middle row of bumps 12, the distance between two adjacent bumps 12 is greater than the distance between two adjacent bumps 12 in the other two rows. Users can set this as needed, and no specific limitation is made here.

[0067] In one embodiment, the diameter d of the protrusion 12 satisfies 0.5mm ≤ d ≤ 5mm, such as... Figure 3 As shown.

[0068] Preferably, the diameter d of the protrusion 12 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc., and its specific value can be set as needed, without being specifically limited here.

[0069] It should be noted that by limiting the range of the diameter d of the protrusion 12 as described above, not only is the friction with the teeth enhanced, ensuring the stability of use and preventing it from falling off during use, but the amount of material used can also be reduced, the cost can be lowered, and it is suitable for mass production.

[0070] More preferably, in this embodiment, the diameter d of the protrusion 12 is 1 mm, which not only reduces the amount of material used to lower the cost, but also significantly increases the friction with the teeth, ensuring the stability of use.

[0071] More preferably, the protrusion 12 is a part of the sphere, such as one-half, one-third, or one-quarter of the sphere, which can be set as needed and is not specifically limited here.

[0072] In one embodiment, the distance t1 between two adjacent rows of protrusions 12 satisfies 1mm ≤ t1 ≤ 3mm, such as Figure 3 As shown.

[0073] Preferably, the distance t1 between two adjacent rows of protrusions 12 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.5mm, 3mm, etc., and the specific value can be set as needed, without being specifically limited here.

[0074] It should be noted that the above-mentioned limitation on t1 ensures that the teeth are stably locked between the two adjacent rows of protrusions 12, guaranteeing stability during use and preventing the occlusal part 1 from shaking or falling out in the mouth.

[0075] More preferably, in this embodiment, the distance between two adjacent rows of protrusions 12 is 2.5mm, which not only accommodates most patients' teeth to expand the range of use, but also ensures the stability of use and prevents shaking or falling off.

[0076] It should be noted that the distance t1 between two adjacent rows of protrusions 12 is the minimum distance between two adjacent rows of protrusions 12 in the first direction x.

[0077] It should also be noted that the first direction x mentioned above is the direction from the proximal end to the distal end.

[0078] In one embodiment, in the first direction x, the size w1 of each row of protrusions 12 satisfies 1mm ≤ w1 ≤ 4mm, such as Figure 3 As shown.

[0079] Preferably, the dimension w1 of each row of protrusions 12 in the first direction x can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc., and the specific value can be set as needed, without being specifically limited here.

[0080] It should be noted that by limiting w1 as described above, it better conforms to the contours of the human upper and lower jaws, thereby making the bite more stable.

[0081] More preferably, in this embodiment, w1 is 1.3mm, which satisfies the contours of the upper and lower jaws of most people, making it more convenient to use.

[0082] It should be noted that: w1 is the maximum dimension of each row of protrusions 12 in the first direction, that is, the distance between the proximal side of the nearest protrusion 12 and the distal side of the farthest protrusion 12 in each row of protrusions 12, such as... Figure 3 As shown.

[0083] In one embodiment, in the second direction y, the dimension w2 of each row of protrusions 12 satisfies 28mm ≤ w2 ≤ 35mm, such as Figure 3 As shown.

[0084] It should be noted that the second direction y is the extension direction of each row of protrusions 12, and is set perpendicular to the first direction x.

[0085] Preferably, in the second direction y, the size w2 of each row of protrusions 12 can be 28mm, 28.1mm, 28.2mm, 28.3mm, 28.4mm, 28.5mm, 28.6mm, 28.7mm, 28.8mm, 28.9mm, 29mm, 29.5mm, 30mm, 30.5mm, 31mm, 31.5mm, 32mm, 32.5mm, 33mm, 33.5mm, 34mm, 34.5mm, 35mm, etc., and the specific values ​​can be set as needed, without being specifically limited here.

[0086] It should be noted that the aforementioned limitation on w2 allows the patient's central and lateral incisors to fit between protrusions 12, thus covering more teeth and making the connection with the teeth more stable, effectively preventing shaking and falling out during use.

[0087] More preferably, in this embodiment, w2 is 32mm, which can cover the central and lateral incisors of most people, not only reducing costs but also ensuring stability in use.

[0088] It should be noted that: the above w2 refers to the maximum distance between the outer edges of the two protrusions 12 in each row of protrusions 12 along the second direction y. Figure 3 As shown.

[0089] Preferably, the w2 of each row of protrusions 12 can be the same or different, and the user can set it according to his or her needs. No specific limitation is made here.

[0090] In one embodiment, in each row of the protrusions 12, the distance t2 between adjacent protrusions 12 satisfies 0 ≤ t2 ≤ 9 mm, such as... Figure 3 As shown.

[0091] Preferably, in each row of protrusions 12, the distance t2 between adjacent protrusions 12 can be 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., and the specific value can be set as needed, without being specifically limited here.

[0092] It should be noted that the above-mentioned limitation on t2 not only ensures the density of the protrusion 12 to significantly enhance its friction with the teeth, but also reduces costs and the number of protrusions 12. At the same time, the limitation on the diameter d of the protrusion 12 makes the effect of stabilizing the teeth better.

[0093] More preferably, in this embodiment, t2 is 1.7 mm, which not only significantly reduces the number of protrusions 12 to reduce costs, but also effectively prevents the central incisors and lateral incisors from slipping out from between the protrusions 12, ensuring their stability in use.

[0094] More preferably, the t2 of the protrusions 12 in different rows can be the same or different, and can be set as needed, without specific limitation here.

[0095] In one embodiment, the occlusal portion 1 further includes a protruding ring 11 disposed at the proximal end, the protruding ring 11 extending radially outward from the outer surface of the occlusal portion 1, such as... Figures 1 to 3 , Figures 8 to 10 As shown.

[0096] Preferably, the protruding ring 11 is fitted onto the proximal end of the occlusal part 1 and fixedly connected thereto, thereby effectively preventing the occlusal part 1 from falling out of the mouth. The protruding ring 11 and the occlusal part 1 can be bonded, heat-fused, or otherwise connected. In other embodiments, the two can also be integrally molded, thereby not only simplifying the process but also improving the structural stability.

[0097] More preferably, the convex ring 11 is a raised structure that extends radially outward from the outer surface of the occlusal portion 1. The convex ring 11 is circular and is arranged around the occlusal portion 1 to significantly increase the contact range and friction with the teeth.

[0098] It should be noted that the engagement of the convex ring 11 and the convex block 12 significantly enhances the friction between the occlusal part 1 and the teeth, effectively preventing them from falling out of the mouth.

[0099] In one embodiment, the engagement portion 1 further includes a support block 13, which is disposed inside the engagement portion 1 and fixedly connected thereto to prevent the engagement portion 1 from collapsing, causing the inner wall to adhere and obstructing airflow. Figure 8 and Figure 9 As shown.

[0100] Preferably, one or more support blocks 13 can be provided, and the user can set them according to their needs, without specific limitations. In this embodiment, two support blocks 13 are provided and located on both sides within the engagement portion 1.

[0101] More preferably, the support block 13 can be a regular geometric shape, such as a sphere, cylinder, cuboid, etc., or it can be an irregular geometric shape, etc. The user can set it according to needs, and no specific limitation is made here.

[0102] Preferably, the support block 13 is fixedly connected to the inner wall of the engagement part 1, such as by bonding, hot melting, or integral molding. The user can set it according to needs, and no specific limitation is made here. In this embodiment, the support block 13 and the engagement part 1 are integrally molded, thereby simplifying the process and improving the structural stability.

[0103] Preferably, the support block 13 is fixed to the inner wall of the biting part 1, so that when the biting part 1 is subjected to pressure, the support block 13 supports the biting part 1, preventing the inner wall from collapsing and causing blockage, which would affect the airflow.

[0104] In one embodiment, the bite device 1 further includes a valve 3 disposed inside the body 2. The body 2 has a through hole 21. A portion of the valve 3 is fixedly connected to the body 2. The valve 3 is positioned opposite the through hole 21 to close the through hole 21 during exhalation and to bend and deform during inhalation to open the through hole 21. Figure 8 As shown.

[0105] Preferably, the through hole 21 penetrates the inner and outer surfaces of the body 2 to enable communication between the second cavity 25 and the external space of the body 2, facilitating gas input. One or more through holes 21 can be provided to meet different ventilation requirements; no specific limitation is made here.

[0106] More preferably, the through hole 21 can be circular, rectangular, or other geometric shapes, etc., without specific limitations.

[0107] More preferably, the through hole 21 can be disposed at the proximal end of the body 2, the distal end of the body 2, or the middle region of the body 2, without specific limitation. In this embodiment, the through hole 21 is disposed in the middle region of the body 2.

[0108] Preferably, the total area of ​​the multiple through holes 21 is greater than 40 square millimeters, and more preferably greater than 57 square millimeters, so as to ensure the patient's normal breathing, reduce lung pressure, and benefit patients with weak lungs.

[0109] It should be noted that in this embodiment, the total area of ​​the multiple through holes 21 is 60 square millimeters, which significantly increases the air intake area and greatly reduces the pressure on the patient's inhalation.

[0110] More preferably, the valve 3 is housed inside the body 2. In its natural state, the valve 3 may or may not be attached to the inner surface of the body 2, without any specific limitation.

[0111] It should be noted that the above natural state refers to the state of valve 3 when it is not under stress.

[0112] Furthermore, valve 3 can be circular, square, or other geometric shapes, etc., without specific limitations. In this embodiment, valve 3 is circular.

[0113] It should be noted that the main body 2 and the biting part 1 are preferably made of silicone material, which can withstand high temperatures of up to 180 degrees Celsius for a long time and up to 220 degrees Celsius for a short time, meeting the requirements of general household disinfection methods, and will not produce harmful substances, making it economical, environmentally friendly and hygienic.

[0114] It should also be noted that the thickness of valve 3 is between 0.1 mm and 0.5 mm, which not only ensures its structural stability but also allows it to deform smoothly during inhalation to meet usage requirements. In this embodiment, the thickness of valve 3 is 0.25 mm.

[0115] Furthermore, the valve 3 is directly opposite the through hole 21, meaning that the projection of the valve 3 toward the through hole 21 can cover the through hole 21. This allows the valve 3 to abut against the inner surface of the body 2 and cover the entire through hole 21 during exhalation, thereby blocking the through hole 21 and preventing gas in the second cavity 25 from being discharged through the through hole 21.

[0116] It should be noted that when the patient bites down on the occlusal part 1 and exhales, the gas enters the second cavity 25 through the first cavity 14. The air pressure in the second cavity 25 increases, which causes the valve 3 to tightly abut against the inner wall of the main body 2 and block the through hole 21, preventing the gas in the second cavity 25 from being discharged through the through hole 21. The distal end of the main body 2 is used to connect with the training structure 4, and the gas in the second cavity 25 is discharged through the training structure 4, thus achieving the purpose of patient exhalation training.

[0117] It should be further explained that when the patient inhales, the gas in the second cavity 25 enters the patient's oral cavity through the first cavity 14. At this time, the air pressure in the second cavity 25 drops. Since the training structure 4 is a one-way valve, it can only allow the gas in the second cavity 25 to be discharged through the training structure 4, but cannot allow external gas to enter the second cavity 25 through the training structure 4. Therefore, part of the valve 3 bends and deforms away from the through hole 21. At this time, the valve 3 no longer blocks the through hole 21, thereby opening the through hole 21. Then, external gas enters the second cavity 25 through the through hole 21, satisfying the patient's inhalation needs.

[0118] In one embodiment, the body 2 is provided with a mounting hole 22, and the valve 3 is provided with a fixing member 33, the fixing member 33 passing through the mounting hole 22 and being fixedly connected to the body 2, such as... Figure 8 As shown.

[0119] Preferably, the mounting hole 22 is provided on the body 2, and the mounting hole 22 penetrates the inner and outer surfaces of the body 2. The mounting hole 22 can be circular, square or other geometric shapes, etc., without specific limitations.

[0120] More preferably, the mounting hole 22 is located near the through hole 21 so that the through hole 21 can be covered when the valve 3 is installed in the body 2. In this embodiment, multiple through holes 21 are arranged around the mounting hole 22, so that the valve 3 can be conveniently installed on the mounting hole 22 and the edge of the valve 3 can cover all the through holes 21, so that a uniform force can be applied to the edge of the valve 3 through multiple sequentially spaced through holes 21, which facilitates the opening and deformation of the edge of the valve 3.

[0121] Preferably, the fixing member 33 is fixedly connected to the valve 3, such as by bonding or hot-melt connection, or it can be integrally molded, thereby improving the structural stability of both. In this embodiment, the valve 3 and the fixing member 33 are integrally molded, which not only simplifies the process, but also has a simple structure and good stability.

[0122] More preferably, the fixing member 33 is disposed in the middle region of the valve 3, that is, one end of the fixing member 33 is fixedly connected to the middle region of the valve 3, so as to fix the middle region of the valve 3 to the inner wall of the body 2, making its structure more stable. In other embodiments, the fixing member 33 can also be fixed to the edge region of the valve 3, etc., and the user can set it according to needs, which is not specifically limited here.

[0123] Furthermore, the fixing member 33 is elongated, and its extension direction intersects with that of the valve 3, so that the valve 3 can be fixed to the inner wall of the body 2 by the fixing member 33. In this embodiment, the extension direction of the fixing member 33 is perpendicular to the plane where the valve 3 is located, so that the valve 3 can fully fit the inner wall of the body 2 when it is fixed to the inner wall of the body 2, and the effect of sealing the through hole 21 is better.

[0124] Furthermore, the fixing member 33 is positioned opposite to the mounting hole 22, so that when the valve 3 is fixed to the inner wall of the body 2, the fixing member 33 passes through the mounting hole 22, so that the fixing member 33 is fixedly connected to the body 2, thereby facilitating the valve 3 to adhere to the inner wall of the body 2.

[0125] Furthermore, the fastener 33 can be snapped together with the body 2 after passing through the mounting hole 22, or it can be heat-fused or bonded, etc., without specific limitations here.

[0126] In one embodiment, the fastener 33 is snapped together with the body 2, such as... Figure 8 As shown.

[0127] Preferably, one end of the fastener 33 is provided with a first latching block 331, the outer diameter of the first latching block 331 being larger than the outer diameter of the fastener 33, so that it can be latched onto one end of the mounting hole 22.

[0128] More preferably, the first snap-fit ​​block 331 is fixedly connected to the fastener 33, such as by bonding or hot-melt connection. In other embodiments, it can also be integrally molded, which not only simplifies the process but also improves the structural stability.

[0129] Preferably, the other end of the fastener 33 is provided with a second latching block 332, the outer diameter of the second latching block 332 being larger than the outer diameter of the fastener 33, so that it can be latched onto the other end of the mounting hole 22.

[0130] Preferably, the second snap-fit ​​block 332 is fixedly connected to the fastener 33, such as by bonding or hot-melt connection. In other embodiments, it can also be integrally molded, which not only simplifies the process but also improves the structural stability.

[0131] More preferably, the outer diameter of the first latching block 331 is larger than the diameter of the mounting hole 22, so that the first latching block 331 is located on one side of the mounting hole 22 and latches onto the inner wall of the body 2.

[0132] Furthermore, the outer diameter of the second latching block 332 is larger than the diameter of the mounting hole 22, so that the second latching block 332 is located on the other side of the mounting hole 22 and latches onto the outer wall of the body 2.

[0133] It should be noted that the first latching block 331 and the second latching block 332 are located on both sides of the mounting hole 22, and are respectively latched onto the inner and outer walls of the body 2 to achieve the latching connection between the fastener 3 and the body 2, thereby firmly fixing the valve 3 to the inner wall of the body 2.

[0134] Furthermore, the first snap-fit ​​block 331 is fixedly connected to the valve 3, such as by bonding or hot-melt connection. In other embodiments, it can also be integrally molded, which not only simplifies the process but also improves the structural stability.

[0135] In one embodiment, the fixing member 33 is fixed to the central region of the valve 3, such as... Figures 8 to 11 As shown.

[0136] Preferably, the fastener 33 is fixed to the central region of the valve 3, specifically, one end of the fastener 33 is fixed to the central region of the valve 3, for example, the first latching block 331 is fixedly connected to the valve 3, thereby achieving a stable connection between the two.

[0137] More preferably, the aforementioned central region can be the location of the center point of valve 3, or it can be a location close to the center point of valve 3. Users can set it according to their needs, and no specific limitation is made here.

[0138] It should be noted that the fixing member 33 is fixed to the central area of ​​the valve 3, so that the valve 3 can cover the through hole 21 surrounding the fixing member 33. In this way, the gas entering through the through hole 21 can apply a balanced force to the valve 3, so that the edge of the valve 3 can bend and deform smoothly.

[0139] In one embodiment, the valve 3 is provided with a plurality of incisions 31, the incisions 31 extending radially from the edge of the valve 3 toward the central region of the valve 3, such as... Figure 10 and Figure 11 As shown.

[0140] Preferably, the notch 31 is designed to allow for rapid deformation when force is applied to the valve 3, so that gas can smoothly and quickly enter the body 2 through the through hole 21.

[0141] More preferably, the cut 31 can be straight, curved, wavy, etc., and its specific shape can be set as needed, without being specifically limited here.

[0142] More preferably, the cut 31 can be set to one or multiple, and can be set as needed, without specific limitations here.

[0143] Preferably, the cut 31 is located at the edge of the valve 3, so that when the gas through the through hole 21 applies force to the edge of the valve 3, the edge of the valve 3 is more likely to bend and deform, thereby allowing the gas to smoothly enter the second cavity 25 of the body 2.

[0144] More preferably, the incision 31 extends radially from the edge of the valve 3 toward the central region of the valve 3, so that the incision 31 extends to the edge of the valve 3, thereby causing the edge of the valve 3 to bend and deform.

[0145] Furthermore, the length of the incision 31 is 10% to 40% of the valve 3 diameter, thereby not only ensuring its structural strength but also allowing it to quickly deform and open the through-hole 21 during inspiration, facilitating smooth inspiration and reducing the patient's inspiratory pressure. In this embodiment, the length of the incision 31 is 27% of the valve 3 diameter.

[0146] Furthermore, the incision 31 and the through hole 21 are staggered to avoid gas leakage during exhalation.

[0147] In one embodiment, the cuts 31 are provided in a plurality of equidistant arrangement along the circumference, such as Figure 10 and Figure 11 As shown.

[0148] Preferably, multiple cuts 31 can be provided and arranged circumferentially at intervals along the edge of the valve 3, so that the edge of the valve 3 is easier to bend and deform, which facilitates the rapid entry of air into the interior of the body 2.

[0149] More preferably, the multiple incisions 31 are arranged equidistantly along the circumference, so that the distance between any two adjacent incisions 31 is consistent. This not only facilitates processing and manufacturing, but also ensures balanced force, allowing it to bend smoothly to open the through hole 21, so that external gas can enter the body 1 when the patient inhales.

[0150] In one embodiment, the valve 3 is provided with a perforation 32, which is offset from the through hole 21, such as... Figures 1 to 11 As shown.

[0151] Preferably, the perforation 32 can be circular, rectangular, elliptical or other geometric shapes, and its specific shape can be set as needed, without being specifically limited here.

[0152] More preferably, the perforations 32 can be arranged in a circumferentially spaced manner, or they can be dispersed in a specific area of ​​the valve 3, etc., and their distribution can be set as needed, without being specifically limited here. In this embodiment, the perforations 32 are arranged in a circumferential manner around the first latching block 331 so as to achieve uniform gas entry into the body 2 in the circumferential direction.

[0153] More preferably, one or more perforations 32 can be provided. When multiple perforations 32 are provided, they are arranged at equal intervals along the circumference, so as to achieve uniform gas entry into the body 2, ensure balanced force, and improve structural stability and service life.

[0154] Preferably, the perforation 32 and the through hole 21 are staggered, so that when the valve 3 is attached to the inner wall of the body 2, the valve 3 can block the through hole 21, preventing the perforation 32 from communicating with the through hole 21 and affecting the sealing effect of the through hole 21; and when the edge of the valve 3 is bent and deformed under force, gas enters from the through hole 21 and partially passes through the perforation 32, thereby improving the efficiency of air circulation, allowing gas to flow into the body 2 faster and in greater quantities, and reducing the patient's pain during inhalation.

[0155] In one embodiment, in its natural state, the edge of the valve 3 is inclined toward the direction away from the inner wall of the body 2.

[0156] It should be noted that the natural state refers to the state in which valve 3 is not under stress.

[0157] Preferably, the edge of the valve 3 is inclined and tilted toward the inner wall away from the body 2, so that it will not block the through hole 21 in its natural state. This allows the patient to enter the interior of the body 2 through the through hole 21 with only a small amount of suction. The valve 3 can also deform to block the through hole 21 during exhalation.

[0158] In one embodiment, in its natural state, the edge of the valve 3 is inclined toward the inner wall of the body 2.

[0159] Preferably, the edge of the valve 3 is inclined toward the inner wall of the body 2, so that the edge of the valve 3 can fit tightly against the inner wall of the body 2, making the sealing effect on the through hole 21 more significant.

[0160] In one embodiment, the valve 3 is inclined in an arc shape or in a straight line.

[0161] Preferably, the edge of valve 3 is inclined in an arc or straight shape, thereby meeting the need to reduce or reduce inspiratory pressure, and is convenient to manufacture and has low cost.

[0162] It should be noted that in other embodiments, the edge of the valve 3 may also be tilted in other ways, such as wavy, etc., which are not specifically limited here.

[0163] In one embodiment, the inner surface of the body 2 is provided with a groove 24, and the valve 3 is received within the groove 24. The bottom surface 241 of the groove 24 is planar. In its natural state, the valve 3 fits against the bottom surface of the groove 241. Figure 7 and Figure 8 As shown.

[0164] Preferably, the groove 24 is formed by recessing inward from the inner surface of the body 2. The cross-section of the groove 24 can be circular, rectangular, etc., and can be set as needed, without specific limitation here.

[0165] More preferably, the number of grooves 24 is the same as the number of valves 3 and corresponds one-to-one, so that each valve 3 is accommodated in the corresponding groove 24.

[0166] Preferably, the groove 24 has a bottom surface 241, which is a plane, thus facilitating not only the processing and manufacturing but also the fitting of the valve 3 onto the bottom surface 241.

[0167] Preferably, the through hole 21 and the mounting hole 22 are provided on the bottom surface 241, so that the fastener 33 can be installed in the mounting hole 22, and the valve 3 is received in the groove 24 and fits against the bottom surface 241, thereby sealing the through hole 21.

[0168] It should be noted that the bottom surface 241 can also be curved, etc., and users can set it according to their needs. No specific limitation is made here.

[0169] More preferably, in its natural state, the valve 3 adheres to the bottom surface 241, thereby sealing the through hole 21, ensuring the sealing effect of the through hole 21, and preventing air leakage caused by unevenness of the bottom surface 241.

[0170] In one embodiment, the present invention also provides a breathing training device, including the bite device 100 and training structure 4 as described in any of the above claims. The distal end of the body 2 is provided with a connecting groove 23, and the proximal end of the training structure 4 is provided with a connecting portion 41 and a connecting block 42 disposed in the connecting portion 41. The connecting portion 41 is received within the inner cavity of the distal end of the body 2 and is press-fitted therewith. The connecting block 42 is received within the connecting groove 23 and is press-fitted therewith. Figures 1 to 12 As shown.

[0171] Preferably, a connecting groove 23 is provided on the inner wall of the distal end of the bite device 100, and the connecting groove 23 extends from the distal end of the body 2 to the proximal end.

[0172] More preferably, the connecting groove 23 can be elongated, or it can be circular or other geometric shapes, etc., without specific limitations.

[0173] More preferably, the training structure 4 is a common breathing training structure on the market. It is a one-way valve, which allows gas to flow from its proximal end to its distal end, but prevents gas from flowing from its distal end to its proximal end. It is existing technology, so it will not be described in detail here.

[0174] Preferably, the training structure 4 has a connecting part 41 at its proximal end. The outer diameter of the connecting part 41 is smaller than the outer diameter of the training structure 4, so that the connecting part 41 can be smoothly inserted into the interior of the distal end of the body 2 to achieve a stable connection between the two.

[0175] More preferably, the outer surface of the connecting portion 41 is provided with a connecting block 42, which extends radially outward from the outer surface of the connecting portion 41.

[0176] Furthermore, the shape of the connecting block 42 is adapted to the shape of the connecting groove 23 so that the connecting block 42 can be inserted into and accommodated in the connecting groove 23, thereby achieving the connection between the two.

[0177] Furthermore, the connecting block 42 and the connecting part 41 can be fixedly connected, such as by bonding or hot-melt connection, or they can be integrally molded, which not only simplifies the process but also improves the structural stability.

[0178] Furthermore, the connecting block 42 is housed in the connecting groove 23 with an interference fit, thereby achieving a stable connection between the training structure 4 and the body 2. The connecting part 41 is housed in the distal inner cavity of the body 2 and fixedly connected to it, thereby not only enhancing the stability of the connection, but also enhancing the sealing effect between the two to prevent air leakage.

[0179] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
