Description

Technical Field

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

[0002] A breathing trainer is a rehabilitation medical device used to enhance respiratory muscle strength, improve lung function, assist in lung rehabilitation treatment, or improve lung performance. When using a breathing trainer, the patient's mouth or nose usually needs to be connected to the breathing trainer to ensure directional control of airflow and accuracy of training effects. For this reason, most breathing trainers need to be equipped with mouthpieces, masks, or nasal masks.

[0003] In the practical application of breathing trainers, some users find it difficult to accept the traditional mouthpiece interface due to psychological sensitivity, strong oral foreign body sensation, or instinctive resistance to keeping foreign objects in their mouths for a long time. They are especially unaccustomed to continuous biting with their teeth for extended periods. This group includes, but is not limited to, children, people with anxiety tendencies, people with hypersensitivity to oral sensation, and some elderly users. For them, keeping a non-food object in their mouths for a long time can easily cause nausea, tension, or even resistance to use, seriously affecting compliance with breathing training and treatment effectiveness.

[0004] However, existing mouthpieces can only be used by patients to bite inside their mouths, and their single function cannot meet the diverse needs of patients. Utility Model Content

[0034] The technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0035] 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.

[0036] In one embodiment, the present invention discloses a mouth connector 100, including a body portion 2, an bite portion 3 disposed at one end of the body portion 2 for connection with a patient's mouth, and a connecting portion 1 disposed at the other end of the body portion 2 for connection with a respiratory medical device, such as... Figures 1 to 10 As shown.

[0037] Preferably, the body part 2 is located between the biting part 3 and the connecting part 1, serving to connect the biting part 3 and the connecting part 1, and has a hollow interior to facilitate gas communication within it, allowing gas to flow from the connecting part 1 to the biting part 3 or from the biting part 3 to the connecting part 1.

[0038] More preferably, the body part 2 can be a hollow cylinder, cone or other regular geometric shape, or a combination of multiple regular geometric shapes or an irregular geometric shape, etc., which can be set as needed, and no specific limitation is made here.

[0039] It should be noted that in this embodiment, the body part 2 adopts a gradually changing contour composed of arcs, curves or straight lines, and the overall shape is a smooth or controlled geometric transition. In the tooth occlusion area, the outer diameter of the body part 2 is the smallest compared with the bite part 3 and the connecting part 1, forming a locally concave structure, which is conducive to tooth occlusion and forms a stable mechanical limit, preventing the mouth connector 100 from axially slipping, improving the reliability of fixation and the safety of use.

[0040] More preferably, the body part 2 is made of materials such as silicone, but it can also be made of other materials, and no specific limitation is made here.

[0041] Preferably, the biting part 3 is disposed at one end of the body part 2, such as at one end of the body part 2 along its length, so as to achieve a stable connection between the two. The biting part 3 can be a regular geometric shape such as a column or a cone, or a combination of multiple regular geometric shapes or an irregular geometric shape, etc., without specific limitations.

[0042] More preferably, the bite part 3 is made of silicone or other materials, but it can also be made of other materials, which is not specifically limited here; the bite part 3 is fixedly connected to the body part 2, such as by bonding or integral molding, which is not specifically limited here.

[0043] Furthermore, the bite patch 3 can be bitten into the patient's mouth, and the patient's teeth bite into the outer surface of the bite patch 3 to achieve communication between the channel 31 and the patient's mouth. Alternatively, it can be attached to the outer surface around the patient's mouth and surround the patient's mouth to cover the patient's mouth, thereby effectively meeting the different needs of the patient and preventing the discomfort caused by the patient constantly biting.

[0044] Furthermore, the connecting part 1 is provided at the other end of the main body part 2, for example, at the other end of the length direction of the main body part 2, so as to achieve a stable connection between the two. The connecting part 1 can be a regular geometric shape such as a column or a cone, or it can be a combination of multiple regular geometric shapes or an irregular geometric shape, etc., without specific limitations.

[0045] Furthermore, the connecting part 1 is made of materials such as silicone, or other materials, without specific limitations. The connecting part 1 is fixedly connected to the main body part 2, such as by bonding or integral molding, without specific limitations.

[0046] It should be noted that the connecting part 1 is used to connect with respiratory medical devices, such as breathing trainers and nebulizers, so that gas can flow between the respiratory medical device and the patient's mouth, thereby achieving the corresponding therapeutic effect.

[0047] In one embodiment, the bite-fitting part 3 is provided with a channel 31. The bite-fitting part 3 includes a major axis a and a minor axis b, wherein the major axis a satisfies 30mm < a < 55mm, and the minor axis b satisfies 10mm < b < 35mm, so that the bite-fitting part 3 includes both a biting state and a fitting state during use. Figures 1 to 10 As shown.

[0048] Preferably, the bite patch 3 has a channel 31 inside, which extends along the length of the mouth connector, so that gas can flow inside the channel 31. One end of the channel 31 is connected to the patient's oral cavity and the other end is connected to the inside of the body 2.

[0049] More preferably, the biting portion 3 includes a long axis a, such as Figure 7 As shown in the top view of the mouth connector 100, the long axis a is the length of the front surface 511 of the bite part 3 near the patient's mouth in the first direction x. The long axis a corresponds to the distance between the left and right corners of the patient's mouth. By limiting the long axis a, the end of the bite part 3 can not only be accommodated inside the patient's mouth for the patient to bite, but also fit onto the outer surface around the patient's mouth to fit and cover the patient's mouth, thereby meeting the different usage needs of the patient.

[0050] It should be noted that the first direction x is the width direction of the mouth connector 100.

[0051] More preferably, the major axis a of the biting part 3 can be any value between 30mm and 55mm, such as 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, 40mm, 45mm, 50mm, 54mm, etc. The specific value can be set as needed and is not specifically limited here.

[0052] It should be noted that by limiting the size of the long axis a of the bite block 3, it can not only be accommodated inside the patient's mouth, but also fit and cover the outer surface of the mouth. If the long axis a is less than or equal to 30 mm, the bite block 3 cannot fit to the outer surface around the patient's mouth, and therefore cannot be used. If the long axis a is greater than or equal to 55 mm, the bite block 3 cannot be accommodated inside the patient's mouth, and therefore cannot be used by the patient, resulting in limitations in the patient's use.

[0053] Preferably, the biting portion 3 further includes a short axis b, such as Figure 2 As shown in the side view of the mouth connector 100, the short axis b is the length of the front surface 511 of the bite part 3 near the patient's mouth in the second direction y. This short axis b corresponds to the distance between the patient's upper and lower lips. By limiting this short axis b, the end of the bite part 3 can not only be accommodated inside the patient's mouth for the patient to bite, but also fit onto the outer surface around the patient's mouth to fit and cover the patient's mouth, thereby meeting the different usage needs of the patient.

[0054] It should be noted that the second direction y is the thickness direction of the mouth connector 100.

[0055] More preferably, the short axis b of the biting part 3 can be any value between 10mm and 35mm, such as 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 25mm, 30mm, 34mm, etc. The specific value can be set as needed and is not specifically limited here.

[0056] It should be noted that the limitation of the short axis b of the bite block 3 allows it to not only be accommodated inside the patient's mouth, but also to fit and cover the outer surface of the mouth. If the short axis b is less than or equal to 10 mm, the bite block 3 cannot fit to the outer surface around the patient's mouth, and therefore cannot be used. If the short axis b is greater than or equal to 35 mm, the bite block 3 cannot be accommodated inside the patient's mouth, and therefore cannot be used by the patient, resulting in limitations in the patient's use.

[0057] It should also be noted that when the front surface 511 of the bite patch 3 is attached to the outer surface around the patient's mouth, the cross-sectional area of ​​the port of the channel 31 is larger than the opening area of ​​the natural lip crease when the patient exhales or inhales, so as to ensure smooth airflow, avoid increased breathing resistance, and maintain good sealing.

[0058] It should also be noted that the aforementioned limitation on the long axis a and short axis b of the bite plate 3 allows the bite plate 3 to not only be housed inside the patient's mouth for the patient to bite, i.e., the bite state of the mouth connector 100, but also to be attached to the outer surface around the patient's mouth for the patient to use, i.e., the attachment state of the mouth connector 100. This increases the patient's usage options and prevents bite fatigue and other phenomena caused by the mouth connector 100 only being able to be used for biting.

[0059] In one embodiment, during the occlusal state, the bite block 3 is received inside the patient's oral cavity so that the channel 31 communicates with the oral cavity, such as... Figures 1 to 10 As shown.

[0060] Preferably, when the bite patch 3 is used by the patient, i.e. in the biting state, the end of the bite patch 3 near the patient is housed inside the patient's mouth so that the patient's teeth bite on the outer surface of the bite patch 3, thereby allowing the bite patch 3 to be securely fixed inside the patient's mouth.

[0061] More preferably, when the bite block 3 is in the biting state, the port of the channel 31 is connected to the patient's oral cavity, thereby allowing gas to flow between the channel 31 and the oral cavity to meet the patient's breathing needs.

[0062] It should be noted that when in the occlusal position, the bite plate 3 can be partially or completely contained inside the oral cavity, thereby meeting different fixation needs.

[0063] In one embodiment, in the fitted state, the front surface 511 of the bite patch 3 adheres to and covers the outer surface around the patient's mouth, and the port of the channel 31 communicates with the oral cavity, such as... Figures 1 to 10 As shown.

[0064] Preferably, when the bite patch 3 is in contact with the outer surface around the patient's mouth, it does not need to be housed inside the oral cavity, thus preventing the patient from experiencing bite fatigue due to constant biting of the bite patch 3 and ensuring patient comfort.

[0065] More preferably, the front surface 511 of the bite block 3 covers the patient's mouth, so that all the air the patient breathes can flow between the channel 31 and the oral cavity, preventing air leakage.

[0066] More preferably, when the bite patch 3 is in the fitted state, the port of the channel 31 is connected to the oral cavity, so that the patient's exhaled air flows into the interior of the channel 31 through the port, or when the patient inhales, the air flows from the channel 31 through the port into the patient's oral cavity, thus meeting the needs of air flow.

[0067] It should be noted that the aforementioned limitation on the bite patch 3 when it is in a fitted state increases the ways in which the mouth connector 100 can be used, allowing it to not only bite but also fit snugly, preventing patients from experiencing bite fatigue due to constantly biting the mouth connector, and increasing patient comfort.

[0068] In one embodiment, the major axis a ranges from 35mm < a < 45mm, and the minor axis b ranges from 15mm < b < 25mm. Figure 2 and Figure 7 As shown.

[0069] Preferably, the long axis a is any value between 35mm and 45mm, so that it can cover the mouth of most patients and can be accommodated in the oral cavity of most patients, such as meeting the use needs of adults and children at the same time, thus making its range optimal, while reducing the cost of use while ensuring that it meets the needs of most patients, and facilitating its promotion and application.

[0070] More preferably, the short axis b is any value between 15mm and 25mm, so that it can cover the mouth of most patients and can be accommodated in the oral cavity of most patients, such as meeting the use needs of adults and children at the same time, thus making its range optimal, while reducing the cost of use while ensuring the use of most patients, and facilitating its widespread use.

[0071] In one embodiment, the radius of curvature R of the front surface 511 of the bite portion 3 satisfies 30mm < R < 80mm, such as Figure 5 As shown.

[0072] Preferably, in the top view of the mouth connector 100, as shown... Figure 5 As shown, the front surface 511 of the bite patch 3 is the surface of the bite patch 3 near the patient's mouth, and is also the surface of the bite patch 3 that fits onto the patient's mouth. It is arc-shaped, so that it can fit effectively onto the patient's mouth.

[0073] More preferably, the radius of curvature R of the front surface 511 in the top view is any value between 30mm and 80mm, such as 31mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 79mm, etc. The specific value can be set as needed and is not specifically limited here.

[0074] It should be noted that the aforementioned limitation on the radius of curvature R allows the front surface 511 of the bite plate 3 to fully conform to the patient's mouth. If the radius of curvature R is less than or equal to 30 mm, it will be too curved to conform to the shape of the patient's mouth and the occlusal contour of the teeth. If the radius of curvature R is greater than or equal to 80 mm, it will be too straight to adapt to the curvature of the oral cavity, resulting in a loose fit with the mouth and tooth contour, affecting the sealing and stability.

[0075] In one embodiment, the front end of the bite portion 3 is provided with a protruding ring 5, and the distance t between the outer peripheral surface of the protruding ring 5 and the inner peripheral surface of the channel 31 satisfies 3mm < t < 8mm, such as Figure 7 As shown.

[0076] Preferably, the protruding ring 5 is disposed at the front end of the bite patch 3, that is, the end of the bite patch 3 near the patient's mouth, and is formed by protruding radially outward from the outer surface of the bite patch 3.

[0077] More preferably, the raised ring 5 is annular, so that it can be arranged around the bite portion 3. The raised ring 5 can not only press against the teeth when the patient bites to increase the stability of use, but also increase the sealing effect when it fits the patient's mouth to prevent air leakage.

[0078] More preferably, the protruding ring 5 is fixedly connected to the biting part 3, such as by bonding or integral molding, thereby increasing the stability of both.

[0079] Preferably, the front surface of the convex ring 5 and the front surface of the bite patch 3 are coplanar, together forming the aforementioned front surface 511, thereby significantly increasing its sealing effect when it is fitted to the patient's mouth and preventing air leakage.

[0080] More preferably, the distance t between the outer peripheral surface of the convex ring 5 and the inner peripheral surface of the channel 31 is any value between 3mm and 8mm, such as 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 7.9mm, etc. The specific value can be set as needed and is not specifically limited here.

[0081] It should be noted that the aforementioned limitation on the distance t is what allows it to increase the contact area with the patient's mouth and prevent air leakage. If the distance t is greater than or equal to 8mm, it will cause the edge to compress the gum tissue, which will not only affect the sealing effect, but may also cause gum redness, pain or soft tissue damage, reducing the comfort and safety of use. If the distance t is less than or equal to 3mm, the sealing effect will be affected because the contact area with the mouth is too small, which will affect the overall use.

[0082] In one embodiment, the thickness h of the convex ring 5 satisfies 1mm < h < 8mm, such as... Figure 5 As shown.

[0083] Preferably, the thickness h of the convex ring 5 is the distance between the front surface and the rear surface of the convex ring 5, that is, the distance between the surface of the convex ring 5 close to the patient's mouth and the surface far away from the patient's mouth.

[0084] More preferably, the thickness h of the convex ring 5 can be any value between 1mm and 8mm, such as 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 7.9mm, etc. The specific value can be set as needed and is not specifically limited here.

[0085] It should be noted that the aforementioned limitation on thickness h ensures the structural strength of the convex ring 5, prevents excessive deformation due to pressure during bonding, ensures sealing performance, and enhances anti-slip ability and stability during biting. If the thickness h is greater than or equal to 8mm, it will cause the ring to penetrate deep into the oral cavity, increasing discomfort. If the thickness is less than or equal to 1mm, the structural strength will be insufficient, affecting sealing performance and anti-slip ability, resulting in poor stability.

[0086] In one embodiment, the convex ring 5 is in the form of a continuous ring, such as... Figures 1 to 10 As shown.

[0087] Preferably, the convex ring 5 is a continuous and closed circular ring, which effectively prevents deformation in the interlocking state, making the anti-slip effect more significant. At the same time, it can significantly enhance its sealing effect in the fitting state, preventing air leakage.

[0088] It should be noted that in other embodiments, the convex ring 5 can also be a non-closed circular ring, which can be set by the user as needed, and no specific limitation is made here.

[0089] In one embodiment, the hardness of the front end portion 51 of the convex ring 5 is less than the hardness of the rear end portion 52 of the convex ring 5, such as... Figure 2 As shown.

[0090] Preferably, the convex ring 5 includes a front end portion 51 near the patient's mouth and a rear end portion 52 away from the patient's mouth, the front end portion 51 and the rear end portion 52 constituting the convex ring 5.

[0091] More preferably, the front end portion 51 abuts against the outer surface around the patient's mouth when in the fitted state, and surrounds the patient's mouth.

[0092] Preferably, the hardness of the front end 51 is less than that of the rear end 52, thereby enhancing the flexibility and fit of the front end 51 when it contacts the mouth, making the bite part 3 more likely to conform to the contour of the mouth, forming an effective seal, reducing pressure and friction on the mouth skin, improving comfort, and reducing the risk of local damage caused by prolonged use; while the greater hardness of the rear end 52 can enhance the overall structural strength of the convex ring 5, prevent axial slippage in the biting state, and ensure the stability and reliability of the breathing process.

[0093] In one embodiment, the hardness m1 of the front end portion 51 of the convex ring 5 satisfies 20HA < m1 < 40HA, such as Figure 2 As shown.

[0094] Preferably, the hardness m1 of the front end 51 of the convex ring 5 can be any value between 20HA and 40HA, such as 21HA, 22HA, 23HA, 24HA, 25HA, 26HA, 27HA, 28HA, 29HA, 30HA, 35HA, 39HA, etc. The specific value can be set as needed and is not specifically limited here.

[0095] It should be noted that the aforementioned limitation on the hardness range of the front end 51, by setting its hardness to a lower level, makes it easier for it to contact the soft tissue of the mouth, improving its flexibility and fit, forming an effective seal, reducing friction, and making it more comfortable to use.

[0096] In one embodiment, the hardness m2 of the rear end portion 52 of the convex ring 5 satisfies 30HA < m2 < 80HA, such as Figure 2 As shown.

[0097] Preferably, the hardness m2 of the rear end 52 of the convex ring 5 can be any value between 30HA and 80HA, such as 31HA, 35HA, 40HA, 45HA, 50HA, 55HA, 60HA, 65HA, 70HA, 75HA, 79HA, etc. The specific value can be set as needed and is not specifically limited here.

[0098] It should be noted that the aforementioned limitation on the hardness range of the rear end 52, by setting its hardness to a relatively large value, can significantly enhance the overall structural strength and rigidity of the convex ring 5, prevent the mouth connector 100 from axially slipping during the biting state, and ensure the stability and reliability of the breathing process.

[0099] In one embodiment, the convex ring 5 includes a first portion 53, which is located at the upper end and / or lower end of the bite portion 3. The included angle c1 between the rear surface of the first portion 53 and the outer peripheral surface of the bite portion 3 satisfies c1≤90°. Figure 2 As shown;

[0100] Preferably, the first part 53 is disposed at the uppermost and / or lowermost end of the protrusion ring 5 of the mouth connector 100 during normal use. The first part 53 may be a portion of the uppermost and / or lowermost end, etc.

[0101] More preferably, the included angle c1 between the rear surface of the first part 53 and the outer peripheral surface of the biting part 3 is any value between 0 and 90 degrees, such as 0 degrees, 1 degree, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, etc. The specific value can be set as needed and is not specifically limited here.

[0102] It should be noted that the aforementioned limitation on angle c1 allows the first part 53 of the mouth connector 100 to fit tightly and securely against the inside of the teeth when in the biting state, significantly enhancing the mechanical stability of the bite, preventing axial slippage of the mouth connector 100, and improving the reliability of the fixation.

[0103] In one embodiment, the convex ring 5 includes a second portion 54 located at the left and / or right end of the bite portion 3, wherein the included angle c2 between the rear surface of the second portion 54 and the outer peripheral surface of the bite portion 3 satisfies c2 > 90°. Figure 5 As shown.

[0104] Preferably, the second part 54 is disposed at the leftmost and / or rightmost end of the protrusion ring 5 of the mouth connector 100 during normal use, and the second part 54 may be a part of the leftmost and / or rightmost end, etc.

[0105] More preferably, the angle c2 between the rear surface of the second part 54 and the outer peripheral surface of the biting part 3 is any value greater than 90 degrees, such as 91 degrees, 92 degrees, 93 degrees, 94 degrees, 95 degrees, etc. The specific value can be set as needed and is not specifically limited here.

[0106] In one embodiment, the connecting portion 1 includes a connecting cavity 11, and a tapered cavity 12 is provided at one end of the connecting cavity 11 near the body portion 2. The inner diameter of the tapered cavity 12 gradually decreases in the direction from the connecting portion 1 towards the body portion 2, such as... Figure 7 As shown.

[0107] Preferably, the connecting part 1 is used to connect to a respiratory medical device. In this embodiment, the respiratory medical device is a respiratory trainer 200. For ease of understanding, the following description uses a respiratory trainer 200 as an example.

[0108] More preferably, the breathing trainer 200 includes a main body 201 and a connector 202 disposed at one end of the main body 201 for connection with the connector 1. The main body 201 and the connector 202 are fixedly connected, such as by bonding or integral molding, so that the two are stably connected.

[0109] Preferably, the connector 202 is housed in the connecting cavity 11, and the outer peripheral surface of the connector 202 abuts against the inner peripheral surface of the connecting cavity 11. The interference fit between the connector 202 and the connecting part 1 achieves a stable connection and enhances the sealing effect, thereby allowing the gas in the mouth connector 100 to flow into the breathing trainer 200, or the gas in the breathing trainer 200 to flow into the mouth connector 100.

[0110] Preferably, the connecting cavity 11 can be in the shape of a cylinder, cuboid, or other geometric shapes, and the shape of the connecting body 202 is adapted to the connecting cavity 11, without being specifically limited here.

[0111] More preferably, the connecting cavity 11 has a tapered cavity 12 at one end near the main body 2, such as... Figure 7 As shown, the conical cavity 12 is located at the end of the connecting cavity 11 near the patient's mouth. The cross-section of the conical cavity 12 is arc-shaped. In the direction from the connecting part 1 toward the body part 2, the inner diameter of the conical cavity 12 gradually decreases, so as to be able to adapt to the connecting body 11 with different outer diameters, so as to achieve a stable and sealed connection with the connecting body 202.

[0112] Furthermore, the end of the connector 202 is provided with a mating part 203, which is arc-shaped and fits with the conical cavity 12, so that the outer surface of the mating part 203 abuts against the inner circumferential surface of the conical cavity 12, thereby achieving a stable and sealed connection between the two.

[0113] It should be noted that the conical cavity 12, with its gradually changing inner diameter, can accommodate breathing trainers 200 of different sizes, expanding its application range. It also replaces the traditional stepped cavity, which requires two molds for injection molding of the mouthpiece connector 100. The existing conical cavity 12 design only requires one mold, which not only significantly reduces costs but also simplifies the molding process. Furthermore, it can accommodate mating parts 203 of different sizes, significantly expanding its application range.

[0114] It should also be noted that: the main body 201 is provided with a marking part 205, and the outer peripheral surface of the connecting part 1 is provided with an alignment part 4. The alignment part 4 and the marking part 205 are arranged opposite to each other, so that when the connecting body 202 is housed in the connecting cavity 11, it is convenient to achieve a correct connection by aligning the positions of the alignment part 4 and the marking part 205, thus preventing misalignment during installation.

[0115] It should also be noted that the outer peripheral surface of the connecting part 1 is provided with several protrusions 6. These protrusions 6 can be block-shaped, annular, etc., and are not specifically limited here. There can be one or multiple protrusions 6, and are not specifically limited here. By providing the protrusions 6, the friction force applied by the hand to the connecting part 1 is increased when the connecting part 1 is installed onto the connecting body 202 of the breathing trainer 200, making it easier to install onto the breathing trainer 200.

[0116] In one embodiment, the connecting cavity 11 is provided with a stepped portion 13, the stepped portion 13 is provided with a positioning groove 131, and the connecting body 202 is provided with a positioning block 204. When the breathing trainer 200 is connected to the mouth connector 100, the connecting body 202 is received within the connecting cavity 11, and the positioning block 204 is received within the positioning groove 131 to limit the breathing trainer 200 and prevent the breathing trainer 200 from rotating. Figure 7 and Figure 8 As shown.

[0117] Preferably, the stepped portion 13 is disposed on the inner wall of the connecting cavity 11, so that its cross-section is stepped. The design of the stepped portion 13 makes the outer wall of the connecting body 202 abut against the stepped portion 13, thereby playing an effective sealing role and preventing the main body 202 from extending excessively into the connecting cavity 11.

[0118] More preferably, the positioning groove 131 can be provided in one, two, three or more, etc. The specific number can be set as needed. When multiple positioning grooves 131 are provided, they are preferably arranged at equal intervals along the circumference. The positioning groove 131 can be in the form of dots, strips, etc. The specific shape can be set as needed, and no specific limitation is made here.

[0119] Preferably, the positioning block 204 is disposed on the outer peripheral surface of the connector 202. The positioning block 204 is integrally formed with the connector 202, or is fixedly connected by bonding or other means. The number of positioning blocks 204 is the same as the number of positioning grooves 131 and corresponds one-to-one. At the same time, the shape of the positioning block 204 is adapted to the shape of the positioning groove 131 so that the positioning block 204 is received in the positioning groove 131, thereby playing a positioning role for both.

[0120] Preferably, when the breathing trainer 200 is connected to the mouth connector 100, the connector 202 is housed in the connecting cavity 11, the outer peripheral surface of the connector 202 abuts against the inner peripheral surface of the connecting cavity 11, and the positioning block 204 is housed in the positioning groove 131, thereby limiting the breathing trainer 200 and preventing it from rotating relative to the mouth connector 100, so that the two can be stably connected together, making it convenient for patients to use.

[0121] In one embodiment, the thickness w3 of the biting portion 3 is greater than the thickness w2 of the body portion 2, such as... Figure 7 As shown.

[0122] Preferably, the thickness w3 of the biting part 3 is greater than the thickness w2 of the body part 2, so that the biting part 3 can provide higher structural rigidity and resistance to deformation, ensuring stability and sealing reliability during use. At the same time, the thickness of the body part 2 is set to be smaller in order to reduce the overall weight, reduce material redundancy, and improve the comfort and portability of use.

[0123] In one embodiment, the thickness w3 of the biting portion 3 is greater than the thickness w1 of the connecting portion 1, such as... Figure 7 As shown.

[0124] Preferably, the thickness w3 of the biting part 3 is greater than the thickness w1 of the connecting part 1, so that the biting part 3 can provide higher structural rigidity and resistance to deformation, ensuring stability and sealing reliability during use. At the same time, the thickness of the connecting part 1 is set to be smaller in order to reduce the overall weight, reduce material redundancy, and improve the comfort of use.

[0125] In one embodiment, the light transmittance of the mouth connector 100 is greater than 50%.

[0126] Preferably, the light transmittance of the connecting part 1, the main body part 2, and the biting part 3 is greater than 50%, so that the patient can directly observe the internal structure of the mouth connector 100 and the connection status with the breathing trainer 200 from the outside, and it is easy to judge whether the assembly is in place, so as to make necessary adjustments, ensure the accuracy and sealing of the assembly, and improve the safety and convenience of use.

[0127] In one embodiment, the roughness of the outer surface of the mouth connector 100 is less than 1 micrometer.

[0128] Preferably, the roughness of the outer surfaces of the connecting part 1, the main body part 2, and the biting part 3 is less than 1 micrometer, making the whole surface smooth and burr-free. This helps to reduce friction and irritation to the oral mucosa, mouth, and gums, and avoids scratches or discomfort during use. It also helps to remove residues such as saliva and secretions, significantly improving cleaning efficiency and facilitating daily cleaning and hygiene maintenance.

[0129] In one embodiment, the mouth connector 100 is made of elastic silicone, rubber-like material, semi-rigid or rigid plastic material.

[0130] Preferably, the connecting part 1, the body 2 and the interlocking part 3 are made of materials such as polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), and polycarbonate (PC), which not only makes them low in cost, but also ensures structural strength and sealing effect, making them suitable for widespread application.
