Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a multifunctional breathing training device. Background Technology

[0002] Obstructive sleep apnea-Hypopnea syndrome (OSAHS, OSAS) is a type of sleep apnea caused by obstructive lesions of the upper airway, and its main symptom is snoring during sleep.

[0003] There are three common causes of snoring: the first is weakness of the oral cavity muscles; the second is weakness of the nasal cavity muscles; and the third is enlarged adenoids. Treatment methods for snoring generally include surgical removal, anti-snoring devices, and exercise-based weight loss therapy.

[0004] Surgical resection is an invasive procedure that involves removing the portion of the upper airway that is significantly narrowed due to enlarged tonsils or adenoids. It is a traumatic intervention that is difficult for patients to accept.

[0005] Anti-snoring therapy is currently the main method for preventing snoring during sleep. This involves using a CPAP machine, anti-snoring patches, mouthguards, or belts before bed to keep the airway clear during sleep. However, because these devices need to be worn constantly during sleep, patient acceptance is low, and snoring often resumes once the device is removed. Therefore, anti-snoring therapy only addresses the symptoms, not the root cause; it can only stop snoring, not cure it.

[0006] Exercise therapy can fundamentally solve the problem of respiratory muscle weakness caused by obesity. However, exercise requires a certain space and time. Nowadays, most people are too busy to find the time and suitable place to exercise for weight loss. Moreover, the effects of exercise are mainly reflected on the surface of the body and cannot provide good direct exercise for the muscles of the throat and nasal cavity.

[0007] The nasal cavity and sinuses are located below the brain, above the throat and mouth, and between the eye sockets. Nasal cavity and sinus diseases often spread to nearby tissues, causing various complications. Since the sinuses are cavities within the bones surrounding the nasal cavity, sinusitis often results from narrowing of the sinus passages, obstructing ventilation and drainage, leading to infection. Consequently, infected sinuses are difficult to cure due to the narrowed passages, and sinusitis can further spread to the nasal cavity, causing rhinitis. Existing medications for sinusitis and rhinitis often have difficulty reaching the lesions. While nebulizer therapy can deliver medication directly to the lesions, sinus congestion often hinders drug delivery.

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

[0009] Sputum is a secretion from the human respiratory tract. It is propelled from the lungs into the upper respiratory tract by the movement of the cilia in the bronchial epithelium, and finally expelled from the body through a normal cough reflex. Normal people produce very little sputum; it is just a small amount of mucus secreted to keep the respiratory tract moist. However, when a person inhales irritating gases, dust, pathogenic bacteria, viruses, or other harmful microorganisms, inflammation of the upper respiratory tract may occur, or lung disease may develop. This leads to increased respiratory secretions, resulting in more sputum and a change in its nature, from sticky sputum to yellow purulent sputum. However, patients often cannot expectorate sputum independently, causing it to accumulate and become even more difficult to cough up.

[0010] Existing breathing trainers are all made of plastic, have a dull appearance, and are not comfortable to hold. Utility Model Content

[0011] This application proposes a multifunctional breathing training device to solve the above problems.

[0012] The embodiments of this application achieve the above objectives through the following technical solutions.

[0013] A multifunctional breathing training device includes a shell, a metal sleeve, an isolation plate, and a vibration unit. The shell has an inner cavity, and an inlet and an outlet communicating with the inner cavity. The metal sleeve is fitted around the outer periphery of the shell. The isolation plate is disposed inside the shell, dividing the inner cavity into a first cavity and a second cavity, and the isolation plate has a through hole. The vibration unit includes a support, a swing arm, and a switch valve. The support is fixedly disposed relative to the shell. The first end of the swing arm is close to the inlet and rotatably connected to the support. The second end of the swing arm is close to the outlet. The switch valve is connected to the first end and the second end and is located in the through hole. The switch valve periodically rotates around the support with the swing arm to open the through hole when the pressure in the first cavity is greater than the pressure in the second cavity, and returns to the through hole under the restoring force of the swing arm, thereby generating vibration sound waves. During this period, the training airflow enters the first cavity through the inlet, flows into the second cavity through the through hole, and then flows out from the outlet. The training airflow is either exhaled airflow or inhaled airflow, wherein the exhaled airflow is the airflow inhaled towards the inlet, and the inhaled airflow is the airflow inhaled from the outlet.

[0014] In some embodiments, the metal sleeve includes a first end face and a second end face that are opposite to each other. The first end face surrounds the air outlet end of the housing, and the second end face surrounds the air inlet end of the housing. The first end face is provided with a chamfer to form a metal marking area.

[0015] In some implementations, the metal sleeve is a one-piece aluminum alloy layer.

[0016] In some embodiments, the metal sleeve also includes a laser-patterned layer.

[0017] In some implementations, the frequency range of the vibrating sound waves is 20–300 Hz.

[0018] In some implementations, the air inlet end has only one air inlet and the air outlet end has only one air outlet, with the training airflow flowing in from the air inlet and flowing out from the air outlet.

[0019] In some embodiments, the multi-functional breathing training device also includes a mouthpiece or a mask that is adapted to the user's mouth and / or nose to provide airflow for training. The mouthpiece or mask is adapted to the inlet end for exhalation, or to the outlet end for inhalation, or to both the inlet end for exhalation and the outlet end for inhalation.

[0020] In some embodiments, the mouthpiece or cover is provided with a first positioning part, and the housing is provided with a second positioning part at the air outlet or air inlet end, the second positioning part being used to cooperate with the first positioning part.

[0021] In some embodiments, the first positioning part is a positioning groove, the second positioning part is a positioning post, and the positioning post and the positioning groove are interference fit; the bite or cover includes an inner wall, the positioning groove is opened in the inner wall, and the bottom surface of the groove where the positioning groove is located extends outward relative to the inner wall.

[0022] In some embodiments, the multi-functional breathing training device also includes a multi-functional connector for connecting the housing, mouthpiece / mask, and external instruments.

[0023] Compared to existing technologies, the multifunctional breathing training device provided in this application can alleviate or treat problems such as snoring caused by oral and nasal muscle groups and adenoid hypertrophy, difficulty in administering medication due to sinus obstruction, as well as expiratory muscle weakness and / or inspiratory muscle weakness, and inability to expectorate sputum voluntarily. Moreover, it has a metal sleeve that can effectively protect the internal structure, has a bright appearance, feels good when held, and makes the generated vibration sound waves have a better propagation speed and intensity, reducing the risk of attenuation during the transmission of vibration sound waves.

[0051] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. Furthermore, all other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0052] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0053] Furthermore, the technical solutions of the various embodiments of this application 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 this application.

[0054] Please see Figure 1 , Figure 2 and Figure 3 This application provides a multifunctional breathing training device 100, including a housing 1, a metal sleeve 1000, an isolation plate 2, and a vibration unit 3. The housing 1 has an inner cavity 10, and an air inlet 11 and an air outlet 12 communicating with the inner cavity 10. The metal sleeve 1000 is sleeved on the outer periphery of the housing 1. The isolation plate 2 is disposed inside the housing 1, dividing the inner cavity 10 into a first cavity 101 and a second cavity 102. The isolation plate 2 has 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 fixedly disposed relative to the housing 1. The first end 311 of the swing arm 31 is close to the air inlet 11 and rotatably connected to the bracket 30. The second end 31 of the swing arm 31... 2. Near the outlet end 12, the switching valve 32 is connected to the first end 311 and the second end 312 and is located in the through hole 20. The switching valve 32 periodically rotates with the swing arm 31 around the bracket 30 to open the through hole 20 when the pressure in the first chamber 101 is greater than the pressure in the second chamber 102, and returns to the through hole 20 under the restoring force of the swing arm 31, thereby generating vibration sound waves. During this period, the training airflow enters the first chamber 101 through the inlet end 11, flows into the second chamber 102 through the through hole 20, and then flows out from the outlet end 12. The training airflow is either exhaled airflow or inhaled airflow, wherein the exhaled airflow is the airflow inhaled into the inlet end 11, and the inhaled airflow is the airflow inhaled into the outlet end 12.

[0055] The vibrational sound waves generated by the multifunctional breathing training device 100 can cause significant vibration in relevant muscle groups. Specifically, it can exercise the oral cavity muscles, nasal cavity muscles, adenoids, open sinus passages, exercise expiratory muscles, exercise inspiratory muscles, and vibrate the airway to assist in sputum expectoration. Therefore, it can alleviate or treat snoring caused by weakness of the oral cavity muscles, snoring caused by weakness of the nasal cavity muscles, snoring caused by adenoid hypertrophy, situations where it is difficult to administer medication due to sinus obstruction, and situations where expiratory and inspiratory muscles are weak and unable to expectorate sputum independently. The metal sleeve 1000 effectively protects the internal structure, has a bright appearance, and feels good to hold, ensuring that the generated vibrational sound waves have good propagation speed and intensity, reducing the risk of attenuation during the transmission of vibrational sound waves.

[0056] In some implementations, the frequency range of the vibrating sound waves is 20–300 Hz. Vibrating sound waves within this frequency range can cause more pronounced vibrations in the relevant muscle groups described above, thereby better addressing issues such as snoring.

[0057] Please see Figure 2 The shell 1 is roughly a hollow cylindrical structure, with the hollow area forming an inner cavity 10. Figure 2 On the left side is the air inlet 11 of the multifunctional breathing training device 100. Figure 2 The right side shown is the air outlet 12 of the multifunctional breathing training device 100. The air inlet 11 and air outlet 12 do not refer to any specific structure, but merely indicate direction. In this embodiment, the switching valve 32 of the multifunctional breathing training device 100 only opens the through-hole 20 to allow gas flow when the gas pressure in the first chamber 101 is greater than the gas pressure in the second chamber 102; therefore, the direction of the training airflow is fixed. The air inlet 11 has only one air inlet 13, and the air outlet 12 has only one air outlet 14. The training airflow flows in through the air inlet 13 and out through the air outlet 14. The air inlet 13 is directly connected to the first chamber 101, while the air outlet 14 is directly connected to the second chamber 102. Compared to training devices with multiple air outlets, the airflow in the second chamber 102 of the multifunctional breathing training device 100 provided in this embodiment is more concentrated, the air pressure is higher, and the vibration sound waves are stronger and more stable.

[0058] The metal sleeve 1000 may not be completely fitted around the outer periphery of the housing 1, for example, it may only be fitted around the middle section of the housing 1. This can protect the housing 1 and also clearly remind the user of the grip position.

[0059] like Figure 1 and Figure 2As shown, in this embodiment, except for the connector area of ​​the air inlet 11 which will be covered by the mouthpiece or the cover, the metal sleeve 1000 is fitted around the outer periphery of the housing 1, covering all exposed areas of the housing 1, thereby protecting all internal structures of the housing 1 and effectively improving its impact resistance.

[0060] When the shell 1 is made of plastic, since the strength of plastic is directly proportional to the propagation speed of ultrasonic waves and inversely proportional to the attenuation of sound waves, the metal sleeve 1000 strengthens the strength and stability of the plastic shell 1, so that the generated vibration sound waves have better propagation speed and intensity, and reduce the risk of attenuation during the transmission of vibration sound waves.

[0061] In some embodiments, the metal sleeve 1000 is a one-piece aluminum alloy layer, not spliced ​​together, without gaps, thereby enhancing the stability of the overall structure and facilitating the propagation of vibration sound waves within the cavity. Moreover, aluminum alloy is characterized by its metallic properties and light weight, making the overall weight of the multifunctional breathing training device 100 lighter and easier to carry.

[0062] The surface of the metal sleeve 1000 may further include a laser pattern layer, that is, the pattern is designed by laser engraving technology according to the needs. The pattern can include directional marks, warning marks, etc. For example, an exhalation mark is engraved near the air inlet 11 and an inhalation mark is engraved near the air outlet 12 of the metal sleeve 1000, which can improve the convenience of use.

[0063] Specifically, the surface of the metal sleeve 1000 is sandblasted, and an oxide film is deposited on the metal surface. Sandblasting enhances the bonding strength of the oxide layer and prevents it from peeling off. The oxide film effectively prevents the metal from corroding in air. Then, various patterns are engraved on the oxide layer using laser engraving to form a laser pattern layer.

[0064] Please see Figure 4 The metal sleeve 1000 includes a first end face 1001 and a second end face 1002 that are opposite to each other. The first end face 1001 surrounds the air outlet end 12 of the housing 1, and the second end face 1002 surrounds the air inlet end 11 of the housing 1. The first end face 1001 is chamfered to form a metal marking area 1003. The second end face 1002 may be a plane.

[0065] After the first end face 1001 is chamfered, a bright metallic color is exposed, forming a metallic marking area 1003, i.e., a high-gloss ring. The metallic marking area 1003 makes the color of the first end face 1001 contrast sharply with the other parts and the color of the second end face 1002. The advantage of this design is that, because the metal sleeve 1000 is directional in the axial direction, the metallic marking area 1003 helps to quickly identify the direction during product assembly, avoiding assembly errors and improving production efficiency.

[0066] like Figure 5 and Figure 6 As shown, after breathing training, users often place the casing 1 upright and place the air outlet 12 against the table surface. The metal marking area 1003 is formed by chamfering, thus creating a gap between the metal sleeve 1000 and the placement surface. The first end face 1001 does not directly touch the table surface, thereby preventing scratches. Please refer to... Figure 2 In addition to the contoured wall 15, the housing 1 may also have a plurality of support walls 16 in the inner cavity 10. These support walls 16 can assist the partition plate 2 in dividing the space of the inner cavity 10. For example, in this embodiment, the support wall 16 includes a radial side wall 161 and a bottom wall 162. The radial side wall 161 blocks a portion of the air inlet 13 along the radial direction of the housing 1, and the bottom wall 162 is close to the air outlet 14.

[0067] Please see Figure 2 and Figure 3 The partition 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 approximately stacked vertically. In some embodiments, the partition plate 2 and the housing 1 are integrally formed. In some embodiments, the partition plate 2 and the housing 1 are manufactured separately and then fixedly connected, for example, by welding, snap-fit ​​connection, etc.

[0068] The isolation plate 2 has 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 can 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.

[0069] In this embodiment, the isolation plate 2 includes a substrate 21 and an extension 22 extending from the substrate 21 toward the first cavity 101. The extension 22 and the substrate 21 can be an integral structure. The substrate 21 can be a plate-like structure. At the location where an opening is required, the substrate 21 extends outward to form the extension 22. The extension 22 is frustoconical in shape. A through hole 20 passes through the extension 22. The central axis is perpendicular to the substrate 21. The through hole 20 is truncated conical in shape. The conical shape is more conducive to guiding the airflow of the first cavity 101 into the second cavity 102.

[0070] By directly forming the through hole 20 on the isolation plate 2, compared to adding an additional structure on the isolation plate 2 for placing the switch valve 32, the internal structure is simplified, the assembly error between other structures and the isolation plate 2 is reduced, the fitting accuracy between structures is improved, and the sealing effect can also be ensured.

[0071] After assembly, the extension 22 extends into the first cavity 101 relative to the base plate 21. There is no need to leave space for the extension 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.

[0072] The support 30 of the vibration unit 3 is fixed to the isolation plate 2. The support 30 serves to support the swing arm 31 and is also the fulcrum of the swing arm 31. Since the isolation plate 2 is fixed relative to the housing 1, the support 30 can be fixed relative to the housing 1. In other embodiments, the support 30 can be fixed to the inner wall 513 of the housing 1. In short, it is sufficient to fix the support 30 relative to the housing 1.

[0073] The swing arm 31 is a plate of any shape, and when placed, its length is arranged along the air inlet 11 and the air outlet 12. The swing arm 31 includes a first end 311 and a second end 312, which are opposite each other. The first end 311 is closer to the air inlet 11, and the second end 312 is closer to the air outlet 12. The swing arm 31 can be rotatably connected to the bracket 30 through one or two rotating shafts.

[0074] The switching valve 32 is located near the second end 312. The shape of the switching valve 32 matches the shape of the air inlet 13, and it can completely or substantially close the air inlet 13.

[0075] In this embodiment, the through hole 20 is a truncated cone shape, and the switch valve 32 includes a tapered portion extending in a direction away from the length of the swing arm 31 to cooperate with the inner wall 513 of the extension portion 22.

[0076] In some embodiments, the switching valve 32 and the rocker arm 31 are connected by a flexible connection. The switching valve 32 is located on the side of the rocker arm 31 near the second end 312 and forms a flexible connection with the rocker arm 31. That is, the connection is made by a flexible material or a spring structure.

[0077] In this embodiment, the vibration unit 3 is bounded by the support 30. The switching valve 32 is located on the side of the support 30 to the second end 312. Since the switching valve 32 drives the swing arm 31 to rotate relative to the support 30, the area from the support 30 to the second end 312 is the power arm of the swing arm 31, while the area from the support 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 asymmetrical 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 approximately the same length as the resistance arm, forming a symmetrical hinge motion structure.

[0078] Whether performing exhalation or inhalation training, the training airflow enters the first chamber 101 from the inlet 11. The training airflow refers to the airflow actively provided by the trainee. It can be provided by the trainee exhaling from the outlet 12 into the shell 1, or by the trainee inhaling from the inhalation end through the shell 1. Whether exhaling or inhaling, the airflow direction within the shell 1 is the same, and the principle of vibration is the same; both belong to the category of training airflow.

[0079] Before the training airflow reaches the switching valve 32, the switching valve 32 completely or substantially closes the through-hole 20. Before the training airflow enters the first chamber 101 and before entering the second chamber 102, regardless of whether the switching 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. Under the action of the pressure difference between the two chambers, the switching valve 32 leaves the through-hole 20, causing the through-hole 20 to open, and the training airflow enters the second chamber 102 from the first chamber 101 through the through-hole 20.

[0080] In the above context, "completely closing the through hole 20" means that the switch valve 32 seals the through hole 20, while "basically closing the through hole 20" means that the switch valve 32 does not completely seal the through hole 20, but it is not completely open either. Rather, 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 is in a basically sealed state, a pressure difference is generated between the first chamber 101 and the second chamber 102, which allows the switch valve 32 to move and open the through hole 20.

[0081] After the through-hole 20 is opened, the switch valve 32 resets under the restoring force of the swing arm 31, completely or substantially closing the through-hole 20, and the training airflow flows out from the outlet 12. The switch valve 32 is located on the swing arm 31, and the swing arm 31 rotates relative to the support 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, causing the switch valve 32 to reset to the through-hole 20, completely or substantially closing the through-hole 20. The training airflow exits the housing 1 from the second chamber 102 through the outlet 12. In this embodiment, the rebound force generated after the first end 311 (resistance arm side) collides with the isolation plate 2 during the rotation of the swing arm 31 causes the swing arm 31 to rotate in the opposite direction.

[0082] The user continuously provides training airflow. When the training airflow enters the first chamber 101 again, the vibration unit 3 repeats the above operation, the pressure difference between the first chamber 101 and the second chamber 102 increases again, and the switching valve 32 opens again. This process repeats, and the vibration unit 3 thus generates vibration sound waves. In this embodiment, the frequency range of the vibration sound waves is 20 to 300 Hz.

[0083] Due to the weight of the switch valve 32, a certain airflow resistance will be generated when the training airflow drives the switch valve 32 to open. This airflow resistance can take into account the training of the user's respiratory muscles or inspiratory muscles, depending on whether exhalation or inhalation is used.

[0084] Specifically, for snoring caused by weakness of the oral muscles, training airflow can be provided through mouth exhalation or mouth inhalation. For snoring caused by weakness of the nasal muscles, training airflow can be provided through nasal exhalation or nasal inhalation. For snoring caused by adenoid hypertrophy, training airflow can be provided through mouth or nose exhalation or mouth or nose inhalation. In cases where medication is difficult to administer due to sinus obstruction, nasal exhalation or nasal inhalation is preferred, followed by mouth exhalation or mouth inhalation. For expiratory muscle training, training airflow can be provided through mouth or nose exhalation. For inspiratory muscle training, training airflow can be provided through mouth or nose inhalation. During sputum expectoration, training airflow can be provided through mouth or nose exhalation or mouth or nose inhalation.

[0085] Since breathing involves the coordinated action 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, just to varying degrees. Therefore, users can choose the training method according to their own situation.

[0086] The training airflow provided through the mouth or nose is not limited to the following methods: for example, it can be provided by connecting the mouthpiece to the housing 1, or by connecting the mouth-fitting mask to the housing 1, or by connecting the nose-fitting mask to the housing 1, or by connecting the mask-fitting mask to both the mouth and nose to the housing 1. Any method that provides the corresponding inhalation or exhalation airflow to the multi-functional breathing training device according to the training purpose is acceptable.

[0087] In some embodiments, by adjusting the resistance of the switching valve 32, the pressure change frequency of the first chamber 101 during exhalation is 20-300 Hz; and the pressure change frequency of the second chamber 102 during inhalation is 20-300 Hz, thereby causing the relevant muscle groups to vibrate at a preset frequency, achieving better therapeutic and exercise effects.

[0088] When the multifunctional breathing training device 100 is used for exhalation, the volume of the first chamber 101 is 5 cm³. 3 ~25cm 3 The volume of the second chamber 102 in the multifunctional breathing training device 100 during inhalation is 5 cm³. 3 ~25cm 3 The multifunctional breathing training device 100 has a first chamber 101 with a volume range of 5 cm³ during exhalation and inhalation. 3~25cm 3 The volume of the second cavity 102 is 5 cm³. 3 ~25cm 3 .

[0089] When the expiratory flow rate is constant, the smaller the volume of the first chamber 101, the greater the pressure in the first chamber 101. Conversely, the smaller the volume of the first chamber 101, the shorter the time required to reach the same pressure when the expiratory flow rate is constant. Therefore, the volume range of the first chamber 101 is set to 5–25 cm³. 3 This allows the pressure changes in the first chamber 101 to occur at a set frequency, ensuring frequency stability.

[0090] When the inhalation flow rate is constant, the smaller the volume of the second chamber 102, the greater the pressure in the second chamber 102. Conversely, the smaller the volume of the second chamber 102, the shorter the time required to reach the same pressure when the inhalation flow rate is constant. Therefore, the volume range of the second chamber 102 is set to 5–25 cm³. 3 This allows the pressure changes in the second chamber 102 to occur at a set frequency, ensuring frequency stability.

[0091] When airflow is supplied through the oral cavity, the frequency range of the vibrational sound waves is 20–110 Hz. Vibrational sound waves within this frequency range will cause significant vibration in the throat and the base of the tongue, which has a significant therapeutic effect on sleep apnea or snoring caused by airflow through the oral cavity. When airflow is supplied through the nasal cavity, the frequency range of the vibrational sound waves is 90–210 Hz. Vibrational sound waves within this frequency range will cause significant vibration in the nasopharynx, which has a significant therapeutic effect on sleep apnea or snoring caused by weakness of the nasal muscles or adenoid hypertrophy.

[0092] In some embodiments, during exhalation, the periodic pressure variation range of the first chamber 101 is 0–90 cmH2O; during inhalation, the periodic pressure variation range of the second chamber 102 is -90–0 cmH2O. This pressure variation range can cause more pronounced vibrations in the relevant muscle groups, thereby achieving the technical effect of this application.

[0093] Please see 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-shaped structure and is disposed at the air outlet 14. The vent cover 17 has multiple vent holes. The number, shape, and size of the vent holes are not limited, as long as they can allow airflow to be discharged. Furthermore, the air outlet cross-sectional area can be adjusted by adjusting the number, shape, and size of the vent holes.

[0094] Specifically, in this embodiment, the air intake cross-sectional area is approximately the area of ​​the air inlet 13. If there is no vent cover 17, and the thickness of the housing 1 is uniform throughout, that is, the area of ​​the air outlet 14 is basically the same as the area of ​​the air inlet 13, then the air outlet cross-sectional area is basically equal to the air intake cross-sectional area. If the vent cover 17 is provided, then the air outlet cross-sectional area is smaller than the air intake cross-sectional area.

[0095] In other embodiments, if the area of ​​the air inlet 13 and the area of ​​the air outlet 14 are substantially the same, a vent cover 17 may be provided at the air inlet 13, while no vent cover 17 may be provided at the air outlet 14, thereby making the air inlet cross-sectional area smaller than the air outlet cross-sectional area.

[0096] In other embodiments, the intake cross-sectional area and the exhaust cross-sectional area can be changed by adjusting the diameter of the intake port 13 and the diameter of the exhaust port 14.

[0097] In other embodiments, the air intake cross-sectional area and the air outlet cross-sectional area can be adjusted by comprehensively adjusting the diameter of the air intake 13, the presence or absence of the vent cover 17 of the air intake 13, the characteristics of the vent hole 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 hole, so as to adjust the pressure of the first chamber 101 and the second chamber 102 as needed.

[0098] In some embodiments, if the multifunctional breathing training device 100 is only used 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 rapidly increase the pressure in the first chamber 101, improving vibration efficiency. At the same time, the relatively large outlet cross-sectional area can quickly expel the gas in the second chamber 102, preventing gas from stagnating in the second chamber 102 and causing eddies that would affect the reciprocating swing of the swing arm 31.

[0099] In some embodiments, if the multifunctional breathing training device 100 is only used for inhalation training, the inlet cross-sectional area can be set to be larger than the outlet cross-sectional area. This helps the external atmospheric pressure to quickly replenish the airflow into the first chamber 101 during inhalation, ensuring a stable pressure difference between the first chamber 101 and the second chamber 102, so that the switching valve 32 can open and close stably.

[0100] 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 to be equal to the outlet cross-sectional area, but it can also be set to have unequal areas. The size relationship between the outlet and inlet cross-sectional areas does not affect the basic function of the multifunctional breathing training device 100 provided in this embodiment.

[0101] Please see Figure 2In some embodiments, the multifunctional breathing training device 100 further includes a resistance unit 4, which includes a first magnetic element 41 and a second magnetic element 42. The first magnetic element 41 is disposed at the second end of the swing arm 31, and the second magnetic element 42 is disposed opposite to the first magnetic element 41 within the housing 1. The magnetic force between the first magnetic element 41 and the second magnetic element 42 can be preset, thereby causing the switch valve 32 to reset into the through hole 20 and close the through hole 20 through the magnetic attraction between the two. At the same time, it can also provide a certain training resistance, that is, the user needs to provide a larger training airflow to open the switch valve 32, thereby achieving a better effect of training the expiratory or inspiratory muscles. Let F1 be the attraction force between the first magnetic component 41 and the second magnetic component 42, F2 be the rebound force provided by the resistance arm of the swing arm 31, and F3 be the weight of the swing arm 31 itself. The torques exerted on the swing arm 31 by the attraction force F1, the rebound force F2, and the weight F3 are M1, M2, and M3, respectively. During the reset process of the switch valve 32, M1 + M2 > M3, ensuring that the switch valve 32 resets smoothly. The frequency of the vibration sound wave can be adjusted by regulating the weight of the swing arm 31 and the resistance of the resistance unit 4.

[0102] Please see Figure 1 , Figure 7 and Figure 8 The multifunctional breathing training device 100 provided in this embodiment also includes a mouthpiece 5. The mouthpiece 5 is adapted to the air inlet end 11 for exhalation, or adapted to the air outlet end 12 for inhalation, or adapted to both the air inlet end 11 for exhalation and the air outlet end 12 for inhalation.

[0103] The mouthpiece 5 conforms more closely to the shape of the mouth and is suitable for biting. It can be made of silicone and can assist users in using the multifunctional breathing training device 100 by exhaling or inhaling through the mouth. When exhaling, connect the mouthpiece 5 to the inlet end 11. When inhaling, connect the mouthpiece 5 to the outlet end 12. The structure of the mouthpiece 5 can be adapted to different functions of the device, taking into account the structure of the inlet end 11 or the outlet end 12, thus adapting to different inlet ends 11 or 12. The mouthpiece 5 can be adapted only to the inlet end 11, providing only exhalation airflow, or only to the outlet end 12, providing only inhalation airflow. It can also be adapted to both the inlet end 11 and the outlet end 12, allowing the user to choose either exhalation or inhalation for training.

[0104] In this embodiment, the bite nozzle 5 is provided with a first positioning part 50, and the housing 1 is provided with a second positioning part 18 at the air outlet 12 or the air inlet 11. The second positioning part 18 is used to cooperate with the first positioning part 50 to ensure a stable connection between the bite nozzle 5 and the housing 1, and to prevent relative movement between the first positioning part 50 and the bite nozzle 5 as a whole and the housing 1 in the circumferential direction.

[0105] The first positioning part 50 can be a positioning groove. The second positioning part 18 can be a positioning post. The two can be interchanged or other structures can be used. In the following figures, the first positioning part 50 is a positioning groove and the second positioning part 18 is a positioning post as an example.

[0106] Please see Figure 7 Taking the air inlet end 11 as an example, the housing 1 is provided with a second positioning part 18 at the air inlet end 11. In this embodiment, there are two second positioning parts 18, which are arranged opposite to each other.

[0107] Please see Figure 8 The bite nozzle 5 is equipped with two first positioning parts 50.

[0108] Please see Figure 9 In some embodiments, one or more second positioning parts 18 may be provided at the air outlet 12 of the housing 1. In this way, the bite 5 can freely choose whether to connect to the air outlet 12 or to the air inlet 11.

[0109] Please see Figure 10 In some embodiments, the positioning pin and the positioning groove are interference-fitted; the bite 5' includes an inner wall 513, the positioning groove is formed in the inner wall 513, and the bottom surface 514 of the groove where the positioning groove is located extends outward relative to the inner wall 513. For example, the length of the bottom surface 514 extending outward relative to the inner wall 513 ranges from 0.5 mm to 2 mm.

[0110] The interference fit can prevent the bite 5 and the housing 1 from detaching due to relative axial movement at the connection end during use.

[0111] 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 others. When the positioning post and the positioning groove are interference-fitted, the positioning post expands outward. Since the wall thickness of the bottom surface 514 of the positioning groove is relatively thin, under the same interference amount, the deformation of the thinner part is greater, causing the thinner part to shrink inward relative to the thicker part, such as... Figure 11 As shown in area A, the contact area between the bottom surface 514 of the groove and the housing 1 is relatively reduced, which may lead to air leakage and affect the performance. 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 bite 5 is inserted into the bottom of the connecting end, the positioning groove contracts inward to compensate, so that the thin and thick parts of the wall are basically flush with the bottom of the connecting end, ensuring that the contact area between the bite 5 and the connecting end is equal. Figure 12 As shown in area B, this ensures a good seal.

[0112] Please see Figure 13In another embodiment, this application also provides a mouthpiece 6, which has an inlet end 63 and a connecting end 64. The connecting end 64 is used to connect with the housing 1. The mouthpiece 6 includes a first peripheral wall 61 and a second peripheral wall 62. The inner diameter of the first peripheral wall 61 is smaller than the inner diameter of the second peripheral wall 62. The first peripheral wall 61 is closer to the inlet end 63 than the second peripheral wall 62. The first peripheral wall 61 is used for airtight connection with one of the air inlet end 11 and the air outlet end 12, and the second peripheral wall 62 is used for airtight connection with the other of the air inlet end 11 and the air outlet end 12.

[0113] In this embodiment, the mouthpiece 6 can be connected to both the air inlet 11 and the air outlet 12. One end of the mouthpiece 6 is directly connected to the housing 1, and the other end is directly at the inlet. The mouthpiece 6 is a hollow tube, and in order to be able to connect to 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 a stepped shape. Correspondingly, the outer diameters of the air inlet 13 and the air outlet 14 of the housing 1 are also adapted accordingly.

[0114] The first circumferential wall 61 of the mouthpiece 6 is closer to the inlet end 63 than the second circumferential wall 62. The inner diameter of the first circumferential wall 61 is smaller than the inner diameter of the second circumferential wall 62. The first circumferential wall 61 can be fitted onto one of the air inlet end 11 and the air outlet end 12 to achieve an airtight connection, while the second circumferential wall 62 is fitted onto the other of the air inlet end 11 and the air outlet end 12 to achieve an airtight connection. Specifically, if the outer diameter of the air inlet end 11 is smaller than that of the air outlet end 12, then the first circumferential wall 61 is fitted to the air inlet end 11, and the second circumferential wall 62 is fitted to 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, then the first circumferential wall 61 is fitted to the air outlet end 12, and the second circumferential wall 62 is fitted to the air inlet end 11. The connection between the mouthpiece 6 and the outer diameter of the housing 1 on both sides of the air inlet end 11 and the air outlet end 12 depends on their design.

[0115] In other embodiments, the bite nozzle 6 provided in this embodiment can be connected to the air inlet end 11 or the air outlet end 12 by screwing, as long as airtightness can be achieved.

[0116] In this embodiment, the first peripheral wall 61 of the bite nozzle 6 is provided with a first positioning part 50, specifically a positioning groove. The housing 1 has a positioning post at the air inlet end 11, and the outer diameter of the air inlet end 11 is relatively small. The first peripheral wall 61 is fitted onto the air inlet end 11. The positioning post and the positioning groove are interlocked. Here, the structure and function of the positioning groove and the positioning post are the same as those of the positioning groove and the positioning post provided in the previous embodiment. The housing 1 has no positioning post at the air outlet end 12, and the outer diameter of the air outlet end 12 is relatively large. Therefore, when the bite nozzle 6 is fitted onto the air outlet end 12, the second peripheral wall 61 is fitted onto the air outlet end 12.

[0117] In other embodiments, the housing 1 may not have a second positioning part 18, and correspondingly, the bite may not have a first positioning part 50; the two can be directly sleeved together.

[0118] Please see Figure 14 In this embodiment, the air outlet 14 is provided with a vent cover 17, the size of which matches the inner diameter of the air outlet 14. The vent cover 17 has vent holes to facilitate exhaust. Figure 2 Compared to the housing 1, the length of the air intake end 11 is significantly shortened, making it more portable.

[0119] Please see Figure 15 In another embodiment, in addition to providing a vent cover 17 at the air outlet 14, a similar vent cover 17 can also be provided at the air inlet 13.

[0120] Please see Figure 16 In another embodiment, the ventilation cover 17 is 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.

[0121] Please see Figure 17 and Figure 18 The multifunctional breathing training device 100 provided in this embodiment also includes a cover 7, which is connected to the housing 1. The cover 7 is adapted to the user's mouth and / or nose to provide airflow for training. The connection method between the cover 7 and the housing 1 can be referred to as mouthpiece 5, mouthpiece 5', and mouthpiece 6.

[0122] The cover 7 can be a mask, covering the user's mouth. The cover 7 can be a nose mask, covering the user's nose. The cover 7 can be a mouth-nose mask, covering both the user's mouth and nose. The cover 7 can replace the mouthpiece 5 to provide airflow for training.

[0123] In this embodiment, one end of the cover 7 is a sealing surface 70, and the other end is a connecting part 71.

[0124] The sealing surface 70 is made of a soft material, such as silicone or TPU, and is mainly used to seal the nasal cavity or oral cavity. The connecting part 71 can be connected to the air inlet end 11 of the shell 1. Different shapes of the sealing surface 70 can be designed to fit snugly and seal against the oral cavity, nasal cavity, or biorbital region. For example, the shape of the sealing surface 70 can be selected as a near-triangular shape to conform to the contour of the human nasal cavity or oral cavity. When the cover 7 covers the nasal cavity, it can provide training airflow through the nose. Compared to providing training airflow through the mouth, it can better exercise the nasal muscle groups, adenoids, open the sinus passages, and exercise the expiratory and inspiratory muscles. Moreover, the cover 7 is more comfortable to use and easier to clean than the mouthpiece 5 which is continuously held in the mouth.

[0125] The connecting part 71 is provided with a first inner cavity 710, and the first inner cavity 710 is provided with a positioning groove 711, so that it can be connected to the air inlet end 11 or the air outlet end 12 provided with a positioning post.

[0126] Please see Figure 19 In another embodiment, the connecting portion 71' has a first inner cavity 721 and a second inner cavity 722 that is directly connected to the first inner cavity 721. The second inner cavity 722 is closer to the end where the non-sealing surface of the cover 7 is located. The inner diameter of the first inner cavity 721 is smaller than the inner diameter of the second inner cavity 722. The first inner cavity 721 is used to connect with the smaller inner diameter of the air inlet end 11 and the air outlet end 12, while the second inner cavity 722 is used to connect with the larger inner diameter of the air inlet end 11 and the air outlet end 12. This allows the same cover 7 to be connected to both the air outlet end 12 and the air inlet end 11, which is suitable for situations where the outer diameters of the air inlet end 11 and the air outlet end 12 of the housing 1 are different.

[0127] When you wear a nasal mask and exhale through it, you inhale through your mouth. When you inhale through the nasal mask, you exhale through your mouth.

[0128] When you wear a mask and exhale through it, you inhale through your nose. When you inhale through the mask, you exhale through your nose.

[0129] When exhaling through the mouth-nose mask, you can freely choose to inhale through your mouth or nose. When inhaling through the mouth-nose mask, you can freely choose to exhale through your mouth or nose. The specific breathing pattern is selected according to training needs.

[0130] Please see Figures 20 to 25 In some embodiments, the mask 7 includes a mask body 75, an inhalation one-way valve 73 and / or an exhalation one-way valve 74, wherein the inhalation one-way valve 73 is disposed on the mask body 75 to assist inhalation and the exhalation one-way valve 74 is disposed on the mask body 75 to assist in exhalation.

[0131] The mask body 75 refers to the mask-shaped structure, which can be equipped with an inhalation one-way valve 73 or an exhalation one-way valve 74, or both an inhalation one-way valve 73 and an exhalation one-way valve 74. The number of these various one-way valves is unlimited.

[0132] Please see Figure 20 and Figure 21An inhalation one-way valve 73 is disposed on the mask body 75. The inhalation one-way valve 73 includes a valve 730 and a stop 731. The valve 730 is located below the stop 731 and close to the sealing surface 70. During exhalation, the valve 730 is blocked by the stop 731, providing a sealing effect. During inhalation, the valve 730 can open to assist inhalation. When exhaling through the mask body 7, the inhalation one-way valve 73 closes. Due to the presence of the inhalation one-way valve 73, the user can inhale through the mask body 7. During inhalation, the inhalation one-way valve 73 opens and provides an inhalation airflow in the opposite direction to the exhalation airflow, thus allowing inhalation without removing the mask body 7. For example, if using the mask body 7 for nasal exhalation, there is no need to remove the mask body 7; inhalation can be done directly through the nose. If using the mask body 7 for oral exhalation, there is no need to remove the mask body 7; inhalation can also be done naturally through the nose. This improves ventilation efficiency and training efficiency.

[0133] Please see Figure 22 and Figure 23 An exhalation one-way valve 74 is disposed on the mask body 75. The exhalation one-way valve 74 includes a valve 740 and a stop 741. The valve 740 is disposed above the stop 741. During inhalation, the valve 740 is blocked by the stop 741, providing a sealing effect. During exhalation, the valve 740 can open 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 exhale through the mask body 7. During exhalation, the exhalation one-way valve 74 opens and provides an exhalation airflow in the opposite direction to the inhalation airflow, thus allowing exhalation without removing the mask body 7. For example, if using the mask body 7 for nasal inhalation, the mask body 7 does not need to be removed, and exhalation can be done directly through the nose. If you are using the mask 7 for mouth inhalation, you do not need to remove the mask 7. You can exhale directly through your mouth or nose, which can improve ventilation efficiency and prevent carbon dioxide from remaining in the body for too long, which can cause dizziness, decreased metabolic efficiency, and other problems, thus improving training efficiency.

[0134] Please see Figure 24 and Figure 25 The mask 7 includes an inhalation one-way valve 73 and an exhalation one-way valve 74, each with a sealing cap 76 for sealing. This design allows for easy switching between inhalation and exhalation training using a single mask 7, and facilitates quick ventilation. When using the mask 7 for nasal or oral inhalation training, the sealing cap 76 seals the inhalation one-way valve 73, and the sealing cap 76 of the exhalation one-way valve 74 is opened for rapid ventilation. Similarly, when using the mask 7 for nasal or oral exhalation training, the sealing cap 76 seals the exhalation one-way valve 74, and the sealing cap 76 of the inhalation one-way valve 73 is opened for rapid ventilation.

[0135] When the mask 7 includes an inhalation one-way valve 73 and an 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 greater than 57 square millimeters, which allows the user to quickly replenish oxygen. The average air intake area of ​​a person is 40 square millimeters to 57 square millimeters, so this setting can ensure the user's normal inhalation level.

[0136] Please see Figure 26 In some embodiments, the multi-functional breathing training device 100 also includes a multi-functional connector 8 for connecting the housing 1, the mouthpiece 5 / mask 7 and the external device 9.

[0137] The multi-functional connector 8 can be a three-way connector, including a first interface 81, a second interface 82, and a third interface 83. The first interface 81 is used to connect to the housing 1, specifically, it can be directly connected to the first cavity 101. The second interface 82 is used to connect to the mouthpiece 5 or the mask 7. The third interface 83 is used to connect to the external device 9. This allows for training through mouth and / or nose breathing via the mask 7, and also extends the training effect through the external device 9. For example, it can be connected to a nebulizer for nebulized drug delivery, directly targeting the lesion for better absorption; or it can be connected to an oxygen supply device to provide oxygen and prevent breathing difficulties and dizziness. The number of external devices 9 can be one, one type, or multiple types, depending on the actual needs.

[0138] Compared to existing technologies, the multifunctional breathing training device 100 provided in this application can alleviate or treat problems such as snoring caused by oral and nasal muscle groups and adenoid hypertrophy, difficulty in administering medication due to sinus obstruction, as well as expiratory muscle weakness and / or inspiratory muscle weakness, and inability to expectorate sputum voluntarily. Moreover, it has a metal sleeve that can effectively protect the internal structure, has a bright appearance, and feels good when held, so that the generated vibration sound waves have a better propagation speed and intensity, reducing the risk of attenuation during the transmission of vibration sound waves.

[0139] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
