Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a multifunctional breathing training device. Background Art

[0002] Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS, OSAS) refers to apnea caused by upper airway obstructive lesions, the main characteristic of which is snoring during sleep.

[0003] There are three common causes of snoring: weak oral muscles, weak nasal muscles, and enlarged adenoids. Treatments for snoring generally include surgical removal, snoring devices, and exercise-based weight loss.

[0004] Surgical resection therapy is to remove the part of the local upper airway stenosis caused by obvious hypertrophy of tonsils and adenoids. It is an invasive intervention that is very traumatic to patients and difficult to accept.

[0005] Snoring prevention therapy is currently the primary method for preventing snoring during sleep. Patients wear a ventilator, anti-snoring patches, mouth guards, or belts before bed to keep their airways open during sleep. However, the constant need to wear the device during sleep has led to low patient acceptance, and patients are prone to snoring again once the device is removed. Therefore, snoring prevention therapy only treats the symptoms, not the root cause; it can only stop snoring, not cure it.

[0006] Exercise therapy for weight loss can fundamentally solve the problem of respiratory muscle weakness caused by obesity, but exercise requires a certain venue and time. Most people are too busy to spare the time and find a suitable venue for weight loss exercises. Moreover, the effect of exercise is mainly reflected on the body surface, and the muscles of the throat and nasal cavity cannot be directly exercised.

[0007] The nasal cavity and sinuses are located beneath the brain, above the throat and mouth, and between the eye sockets. Pathologies in the nasal cavity and sinuses often spread to nearby tissues, leading to a variety of complications. Since the sinuses are cavities within the bones surrounding the nasal cavity, sinusitis often results from narrowing of the sinus passages, which impedes ventilation and drainage, leading to infection. Consequently, the inflammation of infected sinuses is difficult to cure due to the narrowing of the sinus passages, and sinusitis can further spread to the nasal cavity, causing rhinitis. Medications currently available for the treatment of sinusitis and rhinitis often have difficulty reaching the affected area. While nebulizer therapy can deliver medication directly to the affected area, the often blocked sinuses make it difficult to deliver the medication.

[0008] At the same time, weakness of the two major muscle groups, expiratory and inspiratory muscles, is also a cause of nasopharyngeal diseases and related conditions.

[0009] Phlegm is a secretion from the human respiratory tract. It is pushed from the lungs to the upper respiratory tract through the movement of cilia in the bronchial epithelium, and finally coughed out of the trachea and out of the body through the normal cough reflex. Normally, sputum is minimal, consisting of a small amount of mucus secreted to keep the respiratory tract moist. However, when a person inhales irritating gases, dust, pathogenic bacteria, viruses, and other harmful microorganisms, inflammation of the upper respiratory tract may occur, or lung disease may develop. This increases respiratory secretion, sputum volume, and the nature of the sputum changes, from sticky to purulent. However, patients are often unable to expectorate on their own, causing sputum to accumulate and become more difficult to cough up. Summary of the Invention

[0049] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Moreover, based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0050] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0052] See also Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application provides a multifunctional breathing training device 100, comprising a shell 1, an isolation plate 2 and a vibration unit 3; the shell 1 has an inner cavity 10, and an air inlet end 11 and an air outlet end 12 communicated with the inner cavity 10; the isolation plate 2 is arranged in the shell 1, isolating the inner cavity 10 into a first cavity 101 and a second cavity 102, and the isolation plate 2 is provided with a through hole 20; the vibration unit 3 includes a bracket 30, a swing arm 31 and a switch valve 32, the bracket 30 is fixed relative to the shell 1, the first end 311 of the swing arm 31 is close to the air inlet end 11 and is rotatably connected to the bracket 30, the second end 312 of the swing arm 31 is close to the air outlet end 12, and the switch valve 32 is connected to the first end The switch valve 32 has a first end 311 and a second end 312, and is located within the through-hole 20. When the pressure in the first chamber 101 exceeds the pressure in the second chamber 102, the switch valve 32 periodically rotates along with the swing arm 31 around the bracket 30 to open the through-hole 20. The switch valve 32 then returns to the through-hole 20 under the restoring force of the swing arm 31, thereby generating vibration sound waves. During this period, a training airflow enters the first chamber 101 through the air inlet end 11, flows through the through-hole 20 into the second chamber 102, and then flows out of the air outlet end 12. During exhalation, the periodic pressure variation of the first chamber 101 ranges from 0 to 90 cmH2O; during inhalation, the periodic pressure variation of the second chamber 102 ranges from -90 to 0 cmH2O. The training airflow is either expiratory or inspiratory, where expiratory airflow is the airflow exhaled into the air inlet end 11 and inspiratory airflow is the airflow exhaled out of the air outlet end 12.

[0053] This pressure change range can cause the relevant muscle groups to vibrate more obviously. Specifically, it can achieve the effect of exercising the oral muscle groups, nasal muscle groups, adenoids, opening the sinus passages, exercising the expiratory muscles, exercising the inspiratory muscles, and vibrating the respiratory tract to assist in expectoration. Therefore, it can relieve or treat snoring caused by weak oral muscle groups, snoring caused by weak nasal muscle groups, snoring caused by enlarged adenoids, and conditions where medication is difficult due to sinus obstruction, as well as conditions where the expiratory and inspiratory muscles are weak and the expectoration cannot be done independently.

[0054] In some embodiments, by adjusting the resistance of the switch valve 32, the frequency of the pressure change in the first chamber 101 during exhalation is 20 to 300 Hz; during inhalation, the frequency of the pressure change in the second chamber 102 is 20 to 300 Hz, thereby causing the relevant muscle groups to vibrate at a preset frequency to achieve better treatment and exercise effects.

[0055] When the multifunctional breathing training device 100 is used only for exhalation, the volume range of the first cavity 101 is 5cm 3 ~25cm 3 When the multifunctional breathing training device 100 is used only for inhalation, the volume range of the second cavity 102 is 5cm 3 ~25cm 3 When the multifunctional breathing training device 100 is used for both exhalation and inhalation, the volume of the first cavity 101 is 5 cm 3 ~25cm 3 , the volume of the second cavity 102 is 5 cm 3 ~25cm 3 .

[0056] When the exhalation flow rate is constant, the smaller the volume of the first cavity 101 is, the greater the pressure in the first cavity 101 is. From another perspective, the smaller the volume of the first cavity 101 is, the shorter the time it takes to reach the same pressure when the exhalation flow rate is constant. Therefore, the volume range of the first cavity 101 is set to 5 to 25 cm 3 , the pressure change of the first cavity 101 can be carried out according to the set frequency, ensuring the frequency stability.

[0057] When the inspiratory flow rate is constant, the smaller the volume of the second chamber 102 is, the greater the pressure of the second chamber 102 is. From another perspective, the smaller the volume of the second chamber 102 is, the shorter the time it takes to reach the same pressure when the inspiratory flow rate is constant. Therefore, the volume range of the second chamber 102 is set to 5 to 25 cm 3 , the pressure change of the second chamber 102 can be carried out according to the set frequency, ensuring the frequency stability.

[0058] The housing 1 is generally a hollow cylindrical structure, with the hollow area forming an inner cavity 10. On the left side of the diagram is the air inlet 11 of the multifunctional breathing training device 100, and on the right side of the diagram is the air outlet 12 of the multifunctional breathing training device 100. The air inlet 11 and the air outlet 12 do not specifically refer to a certain structure, but merely indicate direction. The on-off valve 32 of the multifunctional breathing training device 100 provided in this embodiment opens the through hole 20 to allow gas to flow only when the gas pressure in the first cavity 101 is greater than the gas pressure in the second cavity 102. Therefore, the direction of the training airflow is fixed.

[0059] The air inlet 11 has a single inlet 13, and the air outlet 12 has a single outlet 14. The training airflow flows in through the inlet 13 and out through the outlet 14. The inlet 13 is directly connected to the first chamber 101, while the outlet 14 is directly connected to the first chamber 101. Compared to breathing exercisers with multiple outlets, the single outlet 14 allows for a more concentrated airflow, preventing it from dispersing, effectively increasing the air pressure in the second chamber 102.

[0060] See also Figure 2 In addition to the contoured wall 15, the housing 1 may also include a plurality of support walls 16 within the inner cavity 10. These support walls 16 assist the partition plate 2 in dividing the inner cavity 10. For example, in this embodiment, the support walls 16 include radial sidewalls 161 and a bottom wall 162. The radial sidewalls 161 shield a portion of the air inlet 13 along the radial direction of the housing 1, while the bottom wall 162 is located near the air outlet 14.

[0061] See also Figure 2 and Figure 3 The isolation plate 2 is a thin plate-like structure connected between the radial sidewall 161 and the bottom wall 162, thereby dividing the inner cavity 10 into a first cavity 101 and a second cavity 102 that are substantially stacked one above the other. In some embodiments, the isolation plate 2 and the housing 1 are integrally formed. In some embodiments, the isolation plate 2 and the housing 1 are manufactured separately and then fixedly connected, for example, by welding or snap-fit connection.

[0062] The isolation plate 2 is provided with a through hole 20, the axis of which is perpendicular or substantially perpendicular to the isolation plate 2. The height of the through hole 20 may be equal to the thickness of the isolation plate 2, that is, the through hole 20 is formed by directly drilling a hole in the isolation plate 2.

[0063] In this embodiment, the isolation plate 2 includes a base plate 21 and an extension portion 22 extending from the base plate 21 toward the first cavity 101. The extension portion 22 and the base plate 21 may be integrally formed. The base plate 21 may be a single plate-like structure. Where an opening is required, the base plate 21 extends outward to form the extension portion 22. The extension portion 22 is truncated cone-shaped. The through hole 20 extends through the extension portion 22, with its central axis perpendicular to the base plate 21. The through hole 20 is truncated conical in shape, which helps guide airflow from the first cavity 101 into the second cavity 102.

[0064] Directly forming the through hole 20 on the isolation plate 2 simplifies the internal structure, reduces the assembly error between other structures and the isolation plate 2, improves the matching accuracy between structures, and ensures the sealing effect, compared to additionally connecting a structure for placing the switch valve 32 on the isolation plate 2.

[0065] After assembly, the extension portion 22 extends into the first cavity 101 relative to the base plate 21, and there is no need to reserve a separate space for the extension portion 22 outside the first cavity 101, thereby reducing the overall height of the multifunctional breathing training device 100 in the axial direction of the through hole 20, further reducing the product volume in this direction, and making the product more compact and practical.

[0066] The bracket 30 of the vibration unit 3 is fixed to the isolation plate 2. The bracket 30 supports the swing arm 31 and also serves as a fulcrum for the swing arm 31. Because the isolation plate 2 is stationary relative to the housing 1, the bracket 30 is secured relative to the housing 1. In other embodiments, the bracket 30 may be fixed to the inner wall 513 of the housing 1. In short, as long as the bracket 30 is fixed relative to the housing 1, it will suffice.

[0067] The swing arm 31 is a plate of any shape. When in use, its length extends along the air inlet 11 and the air outlet 12. The swing arm 31 includes a first end 311 and a second end 312, with the first end 311 being closer to the air inlet 11 and the second end 312 being closer to the air outlet 12. The swing arm 31 can be rotatably connected to the bracket 30 via one or two rotating shafts.

[0068] The switch valve 32 is disposed near the second end 312 . The shape of the switch valve 32 matches the shape of the air inlet 13 , and the air inlet 13 can be completely closed or substantially closed.

[0069] In this embodiment, the through hole 20 is in the shape of a truncated cone, and the switch valve 32 includes a tapered portion extending in a length direction away from the swing arm 31 to cooperate with the inner wall 513 of the extension portion 22 .

[0070] In some embodiments, the switch valve 32 is softly connected to the swing arm 31. The switch valve 32 is disposed on a side of the swing arm 31 near the second end 312 and forms a soft connection with the swing arm 31. That is, the connection is made by a flexible material or a spring structure.

[0071] The vibration unit 3 provided in this embodiment is bounded by the bracket 30, and the switch valve 32 is located on the side of the bracket 30 to the second end 312. Since the switch valve 32 drives the swing arm 31 to rotate relative to the bracket 30, the bracket 30 to the second end 312 is the power arm of the swing arm 31, and relatively, the bracket 30 to the first end 311 is the resistance arm of the swing arm 31. In this embodiment, the power arm is longer than the resistance arm, forming an asymmetric hinge motion structure. This makes the structure of the entire multifunctional breathing training device 100 more compact. In other embodiments, the power arm can also be substantially the same length as the resistance arm, forming a symmetrical hinge motion structure.

[0072] Whether performing exhalation or inhalation training, the training airflow enters the first chamber 101 from the air inlet port 11. The training airflow refers to the airflow actively provided by the trainee. This can be provided by the trainee exhaling from the air inlet port 11 into the housing 1, or by the trainee inhaling from the air inlet port 12. Whether exhalation or inhalation, the flow direction within the housing 1 is the same, the vibration is generated by the same principle, and both constitute training airflow.

[0073] Before the training airflow reaches the on-off valve 32, the on-off valve 32 completely or substantially closes the through-hole 20. Before the training airflow enters the first chamber 101 but not the second chamber 102, regardless of whether the on-off valve 32 completely or partially closes the through-hole 20, the pressure in the first chamber 101 is greater than the pressure in the second chamber 102. Therefore, relatively speaking, the first chamber 101 is a high-pressure chamber, and the second chamber 102 is a low-pressure chamber. Due to the pressure difference between the two chambers, the on-off valve 32 moves away from the through-hole 20, causing the through-hole 20 to open, allowing the training airflow to flow from the first chamber 101 into the second chamber 102 through the through-hole 20.

[0074] In the above, the switch valve 32 "completely closes the through hole 20" means that the switch valve 32 seals the through hole 20, and "basically closes the through hole 20" means that the switch valve 32 does not completely seal the through hole 20, but does not completely open the through hole 20. Instead, it means that, relative to the case of completely sealing the through hole 20, it is not necessary to reach a completely sealed state. As long as it can be in a basically sealed state, so that a pressure difference is generated between the first chamber 101 and the second chamber 102, the switch valve 32 can be activated and the through hole 20 can be opened.

[0075] After the through hole 20 is opened, the switch valve 32 is reset under the restoring force of the swing arm 31, completely closing or substantially closing the through hole 20, and the training airflow flows out from the air outlet 12. The switch valve 32 is provided on the swing arm 31, and the swing arm 31 rotates relative to the bracket 30 due to the movement of the switch valve 32. After the swing arm 31 rotates, it rotates in the opposite direction due to the restoring force provided by the resistance arm, so that the switch valve 32 is reset to the through hole 20, completely closing or substantially closing the through hole 20. The training airflow is discharged from the shell 1 through the air outlet 12 from the second cavity 102. In this embodiment, during the rotation of the swing arm 31, the rebound force generated after the first end 311 (the side of the resistance arm) collides with the isolation plate 2 causes the swing arm 31 to rotate in the opposite direction.

[0076] The user continues to provide training airflow. The next time the training airflow enters first chamber 101, vibration unit 3 repeats the above operation, increasing the pressure difference between first chamber 101 and second chamber 102 again. Switching valve 32 opens again, and this cycle repeats. Vibration unit 3 generates vibration sound waves. In this embodiment, the frequency range of the vibration sound waves is 20 to 300 Hz.

[0077] Due to the deadweight of the switch valve 32, a certain amount of airflow resistance will be generated when the training airflow drives the switch valve 32 to open. This airflow resistance can train the user's respiratory muscles or inspiratory muscles, depending on whether the exhalation method or the inhalation method is used.

[0078] Among them, for snoring caused by weak oral muscle groups, the training airflow can be provided by exhaling or inhaling through the mouth; for snoring caused by weak nasal muscle groups, the training airflow can be provided by exhaling or inhaling through the nose; for snoring caused by enlarged adenoids, the training airflow can be provided by exhaling or inhaling through the mouth or nose. For situations where it is difficult to administer medicine due to sinus obstruction, it is preferred to provide the training airflow by exhaling or inhaling through the nose, and then consider providing the training airflow by exhaling or inhaling through the mouth or mouth. When training the expiratory muscles, the training airflow can be provided by exhaling through the mouth or nose. When training the inspiratory muscles, the training airflow can be provided by inhaling through the mouth or nose. When expectorating, the training airflow can be provided by exhaling or inhaling through the mouth or nose.

[0079] Since breathing involves the coordinated operation of multiple muscles, even mouth breathing can exercise the muscles related to the nose, and even nasal breathing can exercise the muscles related to the mouth, the only difference is the degree of specificity. Therefore, users can choose the training method according to their own situation.

[0080] The training airflow provided by the mouth or nose is not limited to the following methods: for example, it can be provided by connecting a mouthpiece to the housing 1, or by connecting a mask body 7 adapted for the mouth to the housing 1, or by connecting a mask body 7 adapted for the nose to the housing 1, or by connecting a mask body 7 adapted for both the mouth and the nose to the housing 1. It is sufficient as long as the corresponding exhalation or inhalation airflow is provided to the multifunctional breathing training apparatus according to the training purpose.

[0081] See also Figure 2 In this embodiment, the air inlet 13 is open, and the air outlet 14 is provided with a vent cover 17. The vent cover 17 is a plate-like structure, disposed on the air outlet 14, and has multiple vent holes. The number, shape, and size of the vent holes are not limited, as long as they can allow air to escape. Furthermore, the outlet cross-sectional area can be adjusted by adjusting the number, shape, and size of the vent holes.

[0082] Specifically, in this embodiment, the air inlet cross-sectional area is approximately equal to the area of the air inlet 13. If the vent cover 17 is not provided and the housing 1 is uniformly thick, the area of the air outlet 14 is substantially the same as the area of the air inlet 13, making the air outlet cross-sectional area substantially equal to the air inlet cross-sectional area. If the vent cover 17 is provided, the air outlet cross-sectional area is smaller than the air inlet cross-sectional area.

[0083] In other embodiments, if the area of the air inlet 13 is substantially the same as the area of the air outlet 14, a vent cover 17 may be provided at the air inlet 13 but not at the air outlet 14, thereby making the air inlet cross-sectional area smaller than the air outlet cross-sectional area.

[0084] In other embodiments, the air inlet cross-sectional area and the air outlet cross-sectional area may be changed by adjusting the diameter of the air inlet 13 and the diameter of the air outlet 14 .

[0085] In other embodiments, the air inlet cross-sectional area and the air outlet cross-sectional area can also be adjusted by comprehensively adjusting the diameter of the air inlet 13, the presence or absence of the vent cover 17 of the air inlet 13, the characteristics of the vent holes of the vent cover 17, the diameter of the air outlet 14, the presence or absence of the vent cover 17 of the air outlet 14 and the characteristics of the vent holes, so as to adjust the pressure of the first cavity 101 and the second cavity 102 as needed.

[0086] In some embodiments, if the multifunctional breathing training device 100 is used only for exhalation training, the inlet cross-sectional area can be set to be smaller than the outlet cross-sectional area. This allows the exhaled airflow to quickly fill the first chamber 101 and quickly increase the pressure in the first chamber 101, thereby improving vibration efficiency. At the same time, the relatively large outlet cross-sectional area can quickly discharge the gas in the second chamber 102, preventing gas from being trapped in the second chamber 102 and causing vortexes that affect the reciprocating swing of the swing arm 31.

[0087] In some embodiments, if the multifunctional breathing training device 100 is only used for inhalation training, the air inlet cross-sectional area can be set to be larger than the air outlet cross-sectional area, which helps the external atmospheric pressure to replenish the air flow into the first chamber 101 as quickly as possible during inhalation, ensuring that a stable pressure difference is formed between the first chamber 101 and the second chamber 102, so that the switch valve 32 can be opened and closed stably.

[0088] In some embodiments, if the multifunctional breathing training device 100 is used for both exhalation and inhalation training, the inlet cross-sectional area can be set equal to the outlet cross-sectional area, or the areas can be set to be different. The relationship between the outlet cross-sectional area and the inlet cross-sectional area does not affect the basic function of the multifunctional breathing training device 100 provided in this embodiment.

[0089] See also Figure 2 In some embodiments, the multifunctional breathing training device 100 further includes a resistance unit 4, which includes a first magnetic member 41 and a second magnetic member 42. The first magnetic member 41 is disposed at the second end of the swing arm 31, and the second magnetic member 42 is disposed within the housing 1 opposite the first magnetic member 41. The magnitude of the magnetic force between the first magnetic member 41 and the second magnetic member 42 can be preset, so that the magnetic attraction between the first magnetic member 41 and the second magnetic member 42 can reset the switch valve 32 into the through hole 20, closing the through hole 20. At the same time, a certain training resistance can be provided. That is, the user needs to provide a large training airflow to open the switch valve 32, thereby achieving a better training effect on the expiratory muscles or the inspiratory muscles. The suction force between the first magnetic member 41 and the second magnetic member 42 is assumed to be F1, the rebound force provided by the resistance arm of the swing arm 31 is assumed to be F2, and the weight of the swing arm 31 itself is assumed to be F3. The torques acting on the swing arm 31 by the suction force F1, the rebound force F2, and the weight F3 are respectively M1, M2, and M3. During the resetting process of the switch valve 32, M1+M2>M3 is always satisfied, thereby ensuring smooth resetting of the switch valve 32. The frequency of the vibration sound wave can be adjusted by adjusting the weight of the swing arm 31 and the resistance of the resistance unit 4.

[0090] See also Figure 4 The multifunctional breathing training device 100 provided in this embodiment further includes a mouthpiece 5. The mouthpiece 5 is adapted to be connected to the air inlet 11 for exhalation, or to be connected to the air outlet 12 for inhalation, or to be connected to both the air inlet 11 for exhalation and the air outlet 12 for inhalation.

[0091] The mouthpiece 5 fits the shape of the oral cavity better and is suitable for occlusion. It can be made of silicone and can assist the user in using the anti-snoring device 100 by exhaling or inhaling through the mouth. When exhaling, the mouthpiece 5 is connected to the air inlet end 11. When inhaling, the mouthpiece 5 is connected to the air outlet end 12. The structure of the mouthpiece 5 can be adapted according to the different functions of the device, and the structure of the air inlet end 11 or the air outlet end 12 must also be considered, so that it can be adapted to different air inlet ends 11 or air outlet ends 12. The mouthpiece 5 can be adapted only to the air inlet end 11 and only used to provide expiratory airflow, or it can be adapted only to the air outlet end 12 and only used to provide inspiratory airflow. It can also be adapted to both the air inlet end 11 and the air outlet end 12, so that the user can choose to train by exhaling or inhaling at will.

[0092] In this embodiment, the mouthpiece 5 is provided with a first positioning portion 50, and the housing 1 is provided with a second positioning portion 18 at the air outlet end 12 or the air inlet end 11. The second positioning portion 18 is used to cooperate with the first positioning portion 50 to ensure a stable connection between the mouthpiece 5 and the housing 1, and prevent the first positioning portion 50 and the mouthpiece 5 as a whole from moving relative to the housing 1 in the circumferential direction.

[0093] The first positioning portion 50 can be a positioning groove. The second positioning portion 18 can be a positioning post. The two can be interchangeable or adopt other structures. The following figures all use the first positioning portion 50 as a positioning groove and the second positioning portion 18 as a positioning post as an example.

[0094] See also Figure 5 Taking the air inlet end 11 as an example, the housing 1 is provided with a second positioning portion 18 at the air inlet end 11. In this embodiment, there are two second positioning portions 18, which are arranged opposite each other. In some embodiments, one or more second positioning portions 18 may also be provided at the air outlet end 12 of the housing 1. This allows the mouthpiece 5 to freely choose whether to connect to the air outlet end 12 or the air inlet end 11.

[0095] See also Figure 4 The mouthpiece 5 is correspondingly provided with two first positioning portions 50 .

[0096] See also Figure 6 In some embodiments, the positioning post and the positioning groove have an interference fit. The mouthpiece 5' includes an inner wall 513, the positioning groove is formed in the inner wall 513, and the groove bottom surface 514 where the positioning groove is located extends outward relative to the inner wall 513. For example, the length of the groove bottom surface 514 extending outward relative to the inner wall 513 ranges from 0.5 mm to 2 mm.

[0097] The interference fit can prevent the mouthpiece 5 and the housing 1 from falling off due to axial relative movement at the connection end due to shaking during use.

[0098] Because the positioning groove is recessed relative to the inner wall 513, the wall thickness of this part of the inner wall 513 is thinner than the other parts. When the positioning post and the positioning groove are in interference fit, the positioning post expands outwards. Since the wall thickness of the bottom surface 514 of the positioning groove is relatively thin, under the same interference fit, the deformation of the thin part is greater, causing the thin part to shrink inward relative to the thick part. Figure 7 The area A shown in the figure reduces the contact area between the bottom surface 514 of the groove and the housing 1, which may cause air leakage and affect the use effect. Therefore, the bottom surface 514 of the groove where the positioning groove is located can be extended outward relative to the inner wall 513. In this way, when the mouthpiece 5 is inserted into the bottom of the connecting end, the positioning groove shrinks inward to compensate, so that the thin wall and thick wall parts are inserted into the bottom of the connecting end basically flush, ensuring that the contact area between the mouthpiece 5 and the connecting end is equal. Figure 8 As shown in area B, the sealing effect is ensured.

[0099] See also Figure 9 In another embodiment, the embodiment of the present application further provides a mouthpiece 6, which has a free end 63 and a stepped connecting portion 64, and the stepped connecting portion 64 is used to connect to the shell 1; the stepped connecting portion 64 includes a first circumferential wall 61 and a second circumferential wall 62, the first circumferential wall 61 is closer to the free end 63 than the second circumferential wall 62, and the inner diameter of the first circumferential wall 61 is smaller than the inner diameter of the second circumferential wall 62.

[0100] The first circumferential wall 61 is designed to form an airtight connection with the smaller outer diameter of the air inlet end 11 or the air outlet end 12, while the second circumferential wall 62 is designed to form an airtight connection with the larger outer diameter of the air inlet end 11 or the air outlet end 12. Specifically, if the outer diameter of the air inlet end 11 is smaller than that of the air outlet end 12, the first circumferential wall 61 fits the air inlet end 11, while the second circumferential wall 62 fits the air outlet end 12. If the outer diameter of the air outlet end 12 is smaller than that of the air inlet end 11 or the air outlet end 12, the first circumferential wall 61 fits the air outlet end 12, while the second circumferential wall 62 fits the air inlet end 11. The design of the outer diameters of the housing 1 on either side of the air inlet end 11 or the air outlet end 12 determines the connection with the mouthpiece 6.

[0101] In this embodiment, the mouthpiece 6 can be connected to either the air inlet 11 or the air outlet 12. One end of the mouthpiece 6 is directly connected to the housing 1, while the other end is directly connected to the entrance. The mouthpiece 6 is hollow and tubular. To accommodate connections at both ends of the multifunctional breathing training device 100, the inner diameter of the hollow tube of the mouthpiece 6 is not uniform throughout, but rather has steps. Correspondingly, the outer diameters of the air inlet 13 and air outlet 14 of the housing 1 are also adapted accordingly.

[0102] In other embodiments, the mouthpiece 6 provided in this embodiment can be connected to the air inlet end 11 or the air outlet end 12 in a screw connection manner, as long as air tightness can be achieved.

[0103] In this embodiment, the first circumferential wall 61 of the mouthpiece 6 is provided with a first positioning portion 50, specifically a positioning groove. The housing 1 has a positioning post at the air inlet end 11, which has a relatively small outer diameter. The first circumferential wall 61 is sleeved over the air inlet end 11. The positioning post and the positioning groove engage with each other. The structure and function of the positioning groove and the positioning post are identical to those of the previous embodiment. The housing 1 has no positioning post at the air outlet end 12, which has a relatively large outer diameter. Therefore, when the mouthpiece 6 is sleeved over the air outlet end 12, the second circumferential wall 61 sleeves over the air outlet end 12.

[0104] In other embodiments, the housing 1 may not be provided with the second positioning portion 18 , and correspondingly, the mouthpiece may not be provided with the first positioning portion 50 , and the two may be directly socketed.

[0105] See also Figure 10 In this embodiment, the air outlet 14 is provided with a vent cover 17, the size of the vent cover 17 matches the inner diameter of the air outlet 14, and the vent cover 17 has vent holes to facilitate exhaust. Figure 2 Compared with the shell 1 in the figure, the length of the air inlet end 11 is significantly shortened, making it more portable.

[0106] See also Figure 11 In another embodiment, in addition to providing a vent cover 17 at the air outlet 14 , a similar vent cover 17 may also be provided at the air inlet 13 .

[0107] See also Figure 12 In another embodiment, the vent caps 17 are removed from both the air inlet 13 and the air outlet 14. This maximizes the air inlet and outlet cross-sectional areas, improving the efficiency of exhalation and inhalation. It also reduces the overall weight of the device, making it easier to carry.

[0108] See also Figure 13 and Figure 14 The anti-snoring device 100 provided in this embodiment further includes a mask 7 , which is connected to the housing 1 . The mask 7 is adapted to fit the user's mouth and / or nose to provide airflow for training.

[0109] The mask body 7 can be a mouth mask, covering the user's mouth. The mask body 7 can be a nasal mask, covering the user's nose. The mask body 7 can be an oronasal mask, covering both the user's mouth and nose. The mask body 7 can replace the mouthpiece 5 to provide airflow for training.

[0110] In this embodiment, one end of the cover body 7 is a sealing surface 70 , and the other end is a connecting portion 71 .

[0111] The sealing surface 70 is made of a soft material, such as silicone, TPU, etc., and is mainly used to seal the nasal cavity or the oral cavity. The connecting portion 71 can be connected to the air inlet end 11 of the shell 1. Different shapes of the sealing surface 70 can be set to fit and seal with the oral cavity or the nasal cavity or the nose and mouth. For example, the shape of the sealing surface 70 can be selected to be nearly triangular to conform to the nasal cavity contour or the oral cavity contour of the human body. When the mask body 7 covers the nasal cavity, a training airflow can be provided by the nose. Compared with providing a training airflow through the mouth, it can better exercise the nasal muscle groups and adenoids, open the sinus passages, and exercise the expiratory muscles and inspiratory muscles. In addition, compared with the mouthpiece 5 being held continuously in the mouth, the mask body 7 is more comfortable to use and is clean and easy to clean.

[0112] The connecting portion 71 is provided with a first inner cavity 710 , and the first inner cavity 710 is provided with a positioning groove 711 , which, like the mouthpiece 5 or the mouthpiece 5 ′, can be connected to the air inlet end 11 or the air outlet end 12 provided with a positioning column.

[0113] See also Figure 15 , similar to the connection method of the mouthpiece 6. In another embodiment, the connecting portion 71' is formed with a first peripheral wall 721 and a second peripheral wall 722 directly connected to the first peripheral wall 721, forming a stepped connection. The second peripheral wall 722 is closer to the free end of the housing 7 where the non-sealing surface is located. The inner diameter of the first peripheral wall 721 is smaller than that of the second peripheral wall 722. The first peripheral wall 721 is used to connect to the smaller inner diameter of the air inlet end 11 or the air outlet end 12, while the second peripheral wall 722 is used to connect to the larger inner diameter of the air inlet end 11 or the air outlet end 12. This allows the same housing 7 to be connected to both the air outlet end 12 and the air inlet end 11, which is suitable for use in situations where the outer diameters of the air inlet end 11 and the air outlet end 12 of the housing 1 are different.

[0114] Wear a nasal mask and breathe in through your mouth while exhaling through the mask.

[0115] Wear a mask and exhale through the mask, then breathe in through your nose. When you inhale through the mask, then breathe out through your nose.

[0116] When wearing a mask, you can choose to breathe in or out through your mouth or nose. When wearing a mask, you can choose to breathe in or out through your mouth or nose. The specific breathing mode is selected according to training needs.

[0117] See also Figures 16 to 21 In some embodiments, the mask body 7 includes a mask body 75, an inhalation one-way valve 73 and / or an exhalation one-way valve 74. The inhalation one-way valve 73 is arranged on the mask body 75 to assist inhalation, and the exhalation one-way valve 74 is arranged on the mask body 75 to assist in exhalation.

[0118] The mask body 75 is a mask-shaped structure, and can be provided with an inhalation check valve 73 or an exhalation check valve 74, or both an inhalation check valve 73 and an exhalation check valve 74. The number of various check valves is not limited.

[0119] See also Figure 16 and Figure 17 The inhalation check valve 73 is located on the mask body 75 and includes a valve flap 730 and a stopper 731. The valve flap 730 is located below the stopper 731 and near the sealing surface 70. During exhalation, the valve flap 730 is blocked by the stopper 731, providing a seal. During inhalation, the valve flap 730 can open to assist inhalation. When exhaling through the mask body 7, the inhalation check valve 73 is closed. Due to the presence of the inhalation check valve 73, the user can inhale through the mask body 7. During inhalation, the inhalation check valve 73 opens and provides an inhalation flow in the opposite direction of the exhalation flow. This allows the user to inhale directly without removing the mask body 7. For example, if the mask body 7 is used for nasal exhalation, there is no need to remove the mask body 7 and the user can inhale directly through the nose. If the mask body 7 is used for oral exhalation, there is no need to remove the mask body 7 and the user can inhale directly through the mouth or naturally through the nose. This improves ventilation efficiency and training effectiveness.

[0120] See also Figure 18 and Figure 19 , the exhalation one-way valve 74 is arranged on the mask body 75. The exhalation one-way valve 74 includes a valve flap 740 and a stopper 741. The valve flap 740 is arranged above the stopper 741. When inhaling, the valve flap 740 is blocked by the stopper 741 and acts as a seal. When exhaling, the valve flap 740 can be opened to assist exhalation. When inhaling through the mask body 7, the exhalation one-way valve 74 is closed; due to the presence of the exhalation one-way valve 74, the user can use the mask body 7 to exhale. When exhaling, the exhalation one-way valve 74 opens and provides an exhalation airflow in the opposite direction of the inhalation airflow, so that the mask body 7 does not need to be removed when exhaling, and the exhalation can be directly performed. For example, if the mask body 7 is used for nasal inhalation, there is no need to remove the mask body 7, and the nose can be directly exhaled. If the mask body 7 is used for oral inhalation, there is no need to remove the mask body 7, and you can exhale directly through the mouth, or you can exhale naturally through the nose, thereby improving the ventilation efficiency, avoiding the problem of dizziness, decreased metabolic efficiency, etc. caused by carbon dioxide staying in the body for too long, and improving the training efficiency.

[0121] See also Figure 20 and Figure 21The mask body 7 includes an inhalation one-way valve 73 and an exhalation one-way valve 74, and each one-way valve is provided with a sealing cover 76 for sealing the one-way valve. The advantage of such a setting is that the exhalation / inhalation training can be switched through the mask body 7, and ventilation is convenient. When the mask body 7 is used for nasal or oral inhalation training, the sealing cover 76 is used to seal the inhalation one-way valve 73, and the sealing cover 76 of the exhalation one-way valve 74 is opened to quickly ventilate. When the mask body 7 is used for nasal or oral exhalation training, the sealing cover 76 is used to seal the exhalation one-way valve 74, and the sealing cover 76 of the inhalation one-way valve 73 is opened to quickly ventilate.

[0122] When the mask body 7 includes the inhalation one-way valve 73 and the exhalation one-way valve 74, the opening area of the inhalation one-way valve 73 is larger than the opening area of the exhalation one-way valve 74, and the opening area of the inhalation one-way valve 73 is larger than 57 square millimeters, which allows the user to quickly replenish oxygen. The average human intake area is 40 square millimeters to 57 square millimeters, so this setting can ensure the user's normal inhalation level.

[0123] When the intake air flow is provided by the oral cavity, the frequency range of the vibration sound wave is 20 to 110 Hz. The vibration sound waves within this frequency range will cause obvious vibrations in the throat and the root of the tongue, and have a more obvious therapeutic effect on apnea or snoring caused by the oral cavity; when the intake air flow is provided by the nasal cavity, the frequency range of the vibration sound wave is 90 to 210 Hz. The vibration sound waves within this frequency range will cause obvious vibrations in the nasopharynx, and have a more obvious therapeutic effect on apnea or snoring caused by weak nasal muscle groups and enlarged adenoids.

[0124] See also Figure 22 In some embodiments, the multifunctional breathing training device 100 further includes a multifunctional connector 8 , which is used to connect the housing 1 , the mouthpiece 5 / the cover 7 and the external device 9 .

[0125] Multifunctional connector 8 can be a three-way connection, comprising a first interface 81, a second interface 82, and a third interface 83. First interface 81 is used to connect to housing 1, specifically directly to first cavity 101. Second interface 82 is used to connect to mouthpiece 5 or mask 7. Third interface 83 is used to connect to external instrument 9. In addition to enabling oral and / or nasal breathing training through mask 7, external instrument 9 can also be used to expand the training effect. For example, connecting to a nebulizer allows for atomized drug delivery, directly reaching the affected area for better absorption. For example, connecting to an oxygen supply system provides oxygen to prevent respiratory distress and dizziness. The number of external instruments 9 can be one, one type, or multiple, depending on actual needs.

[0126] See also Figure 23In this embodiment, the total gravity of the shell 1 and the contents of the shell 1 (the isolation plate 2 and the vibration unit 3) is F. The shell 1 includes an air inlet end face 110 at the air inlet end 11, and the force arm from the line of action of gravity to the air inlet end face 110 is r1, and the moment is M1, M1=F·r1, wherein 0<M1≤0.6kgf·cm; the shell 1 includes an air outlet end face 120 at the air outlet end 12, and the force arm from the line of action of gravity to the air outlet end face 120 is r2, and the moment is M2, M2=F·r2, wherein 0<M2≤0.6kgf·cm.

[0127] In other embodiments, if the housing 1 is provided with a nebulizer connection portion 8, F includes the gravity of the nebulizer connection portion 8; if an oxygen connection portion 91 is also provided, F also includes the gravity of the oxygen connection portion 91, and so on.

[0128] The support point for the user to bite or wear the multifunctional breathing training device 100 may be located at the air inlet end surface 110, that is, the moment centroid O1, or may be located at the air outlet end surface 120, that is, the moment centroid O2.

[0129] When the support point (centre of moment O1) is located at the intake end face 110, the moment arm from the line of action of gravity F to the intake end face 110 is r1. In the horizontal state, the moment arm r1 is maximum. The moment is M1, where M1 = F·r1, where 0 < M1 ≤ 0.6 kgf·cm.

[0130] When the support point (centre of moment O2) is located at the outlet end surface 120, the moment arm from the line of action of gravity F to the outlet end surface 120 is r2. In the horizontal state, the moment arm r2 is the largest. The moment is M2, M2 = F·r2, where 0 < M2 ≤ 0.6 kgf·cm.

[0131] Such a torque setting will neither cause the multifunctional breathing training device 100 to fall off nor cause the user to use excessive force to bite or wear it. It can also free the user's hands, expanding the use scenarios of the multifunctional breathing training device 100. For example, it can be used while reading, typing, and running. There is no need to deliberately take time out for exercise, which achieves the effect of exercising anytime and anywhere and greatly improves the therapeutic effect.

[0132] In some embodiments, the housing 1 includes an outlet end surface 120 at the outlet end 12. The vertical distance L between the inlet end surface 110 and the outlet end surface 120 is ≤ 150 mm. A housing 1 length less than 150 mm facilitates easier gripping or wearing of the multifunctional respiratory training device 100 by the user.

[0133] Existing respiratory trainers are large, heavy, and difficult to carry. They can only be placed in a fixed location for use, which greatly limits the user's range of movement and is not conducive to increasing the user's training frequency or reducing the user's training burden. The multifunctional respiratory training device 100 provided in this embodiment can operate using both expiratory and inspiratory airflows. It is small in size, lightweight, and suitable for biting or wearing, greatly reducing the user's training burden, facilitating increased training frequency, and ensuring training effectiveness. Compared to the existing technology, the multifunctional respiratory training device 100 provided in this application can alleviate or treat problems related to snoring caused by enlarged oral muscles, nasal muscles, and adenoids, sinus obstruction and difficulty in administering medication, expiratory muscle weakness and / or inspiratory muscle weakness, and inability to expectorate.

[0134] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
