Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a respiratory training device. Background Technology
[0002] Obstructive sleep apnea syndrome mainly refers to the cessation of breathing caused by obstructive lesions of the upper airway, which is commonly known as snoring. The most common cause of snoring is weakness of the airway muscles. Weakness or thickening of the neck and pharyngeal muscles can easily lead to airway obstruction. Current treatments for snoring mainly include surgery, anti-snoring devices, and exercise-based weight loss therapy.
[0003] Anti-snoring therapy is a commonly used method to prevent snoring during sleep. It mainly involves wearing a CPAP machine, anti-snoring patch, anti-snoring mouthguard, or anti-snoring belt before bed to ensure unobstructed breathing during sleep. However, this method has many drawbacks. For example, patients have low acceptance of the device, and once the device is removed, patients are likely to resume snoring, so it cannot fundamentally cure snoring. While exercise and weight loss therapy can fundamentally solve the problem of weak respiratory muscles caused by obesity, exercise requires a certain space and time, which most people are too busy to exercise. Moreover, the effects of exercise are mainly reflected on the surface of the body, and the effect on the muscles of the throat and nasal cavity is not significant.
[0004] Therefore, a respiratory training device is needed to exercise the respiratory muscle groups to achieve the purpose of snoring treatment. Existing respiratory training devices have unsatisfactory training effects, and the airflow formed by the patient during exhalation or inhalation is easily disordered inside the respiratory training device, which increases energy consumption and affects the training effect of the muscle groups. Utility Model Content
[0005] In order to overcome the above-mentioned technical problems, this utility model provides a respiratory training device that can solve the above-mentioned technical problems.
[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0012] Preferably, the first port is an end of the housing; or, the first port protrudes from the end face of the housing and is disposed around the first cavity.
[0013] Preferably, the vibration sound wave generating device includes a housing, a partition disposed within the housing, a swing arm, and a valve disposed on the swing arm. The partition is used to divide the space within the housing into a first cavity and a second cavity. The partition has a through hole connecting the first cavity and the second cavity. The swing arm is used to swing within the housing to periodically swing to a first position and a second position. When the swing arm swings to the first position, the valve blocks the through hole, and when the swing arm swings to the second position, the valve does not block the through hole.
[0014] Preferably, the first cavity is an air inlet cavity and the second cavity is an air outlet cavity; or, the first cavity is an air outlet cavity and the second cavity is an air inlet cavity.
[0015] Preferably, the outer shell has a first partition located on one side of the partition and a second partition located on the other side of the partition. The first partition and the second partition are respectively fixedly connected to the inner surface of the outer shell. One end of the partition is fixedly connected to the first partition and the other end is fixedly connected to the second partition.
[0016] Preferably, the vibration sound wave generating device further includes a support shaft fixed inside the housing, one end of the swing arm being rotatably connected to the support shaft so that the swing arm swings around the support shaft; and / or, the vibration sound wave generating device further includes a first magnet fixed to the free end of the swing arm and a second magnet fixed to the inner wall of the housing, the first magnet and the second magnet attracting each other to increase the resistance to the swing of the swing arm.
[0017] This utility model has at least the following beneficial effects:
[0018] This novel respiratory training device limits the ratio of the overlapping area of the first opening and the first cavity when projected onto the projection surface to the projected area of the first cavity. This allows the airflow generated by the patient's exhalation or inhalation to flow directly between the first opening and the first cavity, preventing airflow obstruction and turbulence that could affect the transmission of vibrational sound waves and thus the training effect on muscle groups and sputum expectoration. Furthermore, the vibrational sound waves generated by the device can be transmitted into the respiratory tract to train the muscles within the respiratory tract, effectively treating snoring. At the same time, the vibrational sound waves help loosen sputum on the inner wall of the respiratory tract, facilitating sputum expectoration. Attached Figure Description

[0033] The technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
[0034] In this specification, axial direction refers to the direction parallel to the line connecting the distal and proximal centers of the component; radial direction refers to the direction perpendicular to the aforementioned axial direction.
[0035] In one embodiment, the present invention discloses a respiratory training device 100, comprising: a vibration sound wave generating device 1, used to generate vibration sound waves through a patient's exhalation or inhalation and transmit them into the respiratory tract, the vibration sound wave generating device 1 including a first cavity 18 located inside and a first port 113 communicating with the first cavity 18; a mouthpiece 2 including a first opening 21 and a second opening 22 connected to the first port 113, wherein the ratio a of the area of the overlapping region of the first opening 21 and the first cavity 18 when projected onto a projection plane dd to the projected area of the first cavity 18 satisfies a≥60%, the projection plane dd is perpendicular to the central axis cc of the vibration sound wave generating device 1, such as... Figures 1 to 8 As shown.
[0036] Preferably, the vibration sound wave generating device 1 is used to generate vibration sound waves. The vibration sound waves are transmitted to the interior of the vibration sound wave generating device 1 through the airflow generated by the patient's exhalation or inhalation, and then generated by the swing arm 13 inside the device. The vibration sound waves are mechanical vibration sound waves with a vibration frequency of 20Hz to 300Hz. Since they are generated through the patient's exhalation or inhalation, their frequency and amplitude are more compatible with the frequency of the patient's exhalation or inhalation. As a result, after they are transmitted to the patient's airway, the exercise effect on the muscle groups in the airway is more significant, the treatment effect on snoring is more ideal, and it is also conducive to the loosening of phlegm on the inner wall of the airway, which is beneficial for expectoration.
[0037] More preferably, the first cavity 18 is disposed inside the vibration sound wave generating device 1 and is used for airflow transmission. Specifically, the first cavity 18 can be an air inlet cavity, that is, external gas enters the interior of the vibration sound wave generating device 1 through the first cavity 18, or the first cavity 18 can be an air outlet cavity, that is, gas inside the vibration sound wave generating device 1 is discharged from the first cavity 18. The user can configure it according to needs, and no specific limitation is made here. In this embodiment, the first cavity 18 is an air inlet cavity. For ease of understanding, the following description will use the first cavity 18 as an air inlet cavity as an example.
[0038] More preferably, the first port 113 is one end of the vibration sound wave generating device 1, such as one end along its length, etc., without specific limitation. The first port 113 is connected to the first cavity 18, so that gas can communicate between the first port 113 and the first cavity 18. In this embodiment, since the first cavity 18 is an air inlet cavity, the first port 113 is also an air inlet port, allowing external gas to enter the first cavity 18 from the first port 113. In other embodiments, when the first cavity 18 is an air outlet cavity, the first port 113 is an air outlet port, without specific limitation.
[0039] Preferably, the shape of the first port 113 can be circular, or square, semi-circular, etc., and the user can set it according to needs. No specific limitation is made here.
[0040] More preferably, the mouthpiece 2 is disposed at one end of the vibration sound wave generating device 1 and is disposed opposite to the first port 113. The mouthpiece 2 is used to bite the patient's mouth to enable the patient to exhale or inhale, so that the gas generated by the patient's exhale enters the first cavity 18 through the mouthpiece 2 and the first port 113, or the gas in the first cavity 18 is inhaled into the patient's respiratory tract after passing through the first port 113 and the mouthpiece 2 when the patient inhales.
[0041] Furthermore, the first opening 21 is provided at one end of the mouthpiece 2, such as at one end along the length of the mouthpiece 2. The first opening 21 is used by the patient to bite down so as to enable gas flow with the vibrating sound wave generating device 1.
[0042] Furthermore, a second opening 22 is provided at the other end of the mouthpiece 2, such as at the other end along the length of the mouthpiece 2. The second opening 22 is used to connect with the first port 113, thereby enabling the interior of the mouthpiece 2 to communicate with the interior of the vibration sound wave generating device 1, facilitating the flow of gas and the transmission of vibration sound waves to the patient's airway.
[0043] Furthermore, when the first opening 21 and the first cavity 18 are simultaneously projected onto the projection plane dd, the ratio a of the area of their overlapping region to the projected area of the first cavity 18 is greater than or equal to 60%, such as 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%, 110%, 120%, etc. The specific value can be set as needed and is not specifically limited here.
[0044] It should be noted that the limitation of the above-mentioned comparison value a allows the projection of the first opening 21 to cover most of the projection of the first cavity 18, thereby allowing the gas entering from the first opening 21 to flow directly into the first cavity 18, or the gas in the first cavity 18 to flow directly into the patient's airway through the first opening 21, reducing the effect of airflow obstruction and the resulting airflow turbulence, ensuring smooth airflow, and facilitating the rapid entry of vibration sound waves into the patient's airway, reducing the loss of vibration sound wave energy.
[0045] It should also be noted that the projection plane dd at this point is perpendicular to the central axis cc of the vibration sound wave generating device 1, which is beneficial for the first opening 21 and the first cavity 18 to be arranged sequentially along the length of the vibration sound wave generating device 1, and is conducive to the flow of gas.
[0046] It should also be noted that: in Figure 7In the middle, a portion of the projection of the first opening 21 overlaps with the projection of the first cavity 18, while... Figure 8 In this embodiment, the projection of the first opening 21 is entirely within the projection of the first cavity 18. In other embodiments, the alignment of the projection of the first opening 21 with the projection of the first cavity 18 can be set as needed, as long as it meets the above-mentioned ratio a limitation, and no specific limitation is made here.
[0047] In one embodiment, the ratio b of the projected area of the first opening 21 to the projected area of the first cavity 18 satisfies 60% ≤ b ≤ 120%, such as... Figure 7 and Figure 8 As shown.
[0048] Preferably, the projection of the first opening 21 can be a circle, square, ellipse or other shapes, which can be set as needed and are not specifically limited here.
[0049] More preferably, the projection of the first cavity 18 can be a circle, a square, a semicircle, or other shapes, which can be set as needed and are not specifically limited here.
[0050] More preferably, the ratio b of the projected area of the first opening 21 to the projected area of the first cavity 18 is any value between 60% and 120%, such as 60%, 61%, 62%, 63%, 64%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%, 105%, 110%, 115%, 120%, etc. The specific value can be set as needed and is not specifically limited here.
[0051] It should be noted that the limitation of the above ratio b range is intended to prevent the area of the first opening 21 relative to the first cavity 18 from being too small, thus affecting the flow of gas into or out of the first opening 21, and to prevent the area of the first opening 21 relative to the first cavity 18 from being too large, thus affecting the flow of gas into the first cavity 18. This is conducive to achieving smooth airflow and the transmission of vibration sound waves into the patient's airway.
[0052] In one embodiment, the projection of the first opening 21 overlaps the projection of the first cavity 18.
[0053] Preferably, the projection of the first opening 21 covers the projection of the first cavity 18, that is, the projection of the first cavity 18 is inside the projection of the first opening 21, so that the first cavity 18 is completely facing the first opening 21, and the gas can flow smoothly from the first cavity 18 into the first opening 21 or from the first opening 21 into the first cavity 18, thereby maximizing the efficiency of airflow and reducing airflow turbulence and energy loss of vibration sound waves.
[0054] More preferably, the projection of the first opening 21 is the same as or completely overlaps with the projection of the first cavity 18, or the projection of the first opening 21 is larger than the projection of the first cavity 18, etc., which can be set as needed and are not specifically limited here.
[0055] In one embodiment, the ratio b is 100%.
[0056] Preferably, the ratio b is 100%, that is, the projected area of the first opening 21 is the same as the projected area of the first cavity 18, so that the gas can flow smoothly between the two.
[0057] More preferably, the projection of the first opening 21 and the projection of the first cavity 18 can completely overlap or partially overlap, and the user can set it as needed, without making specific limitations here.
[0058] In one embodiment, the outer surface of the first port 113 is provided with an L-shaped groove, the L-shaped groove including an inlet portion 114 and a latching portion 115, and the inner peripheral surface of the second opening 22 is provided with a latching block 23, the latching block 23 being used to pass through the inlet portion 114 and latch onto the latching portion 115, thus transitionally engaging with it. Figures 1 to 6 As shown.
[0059] Preferably, the L-shaped groove is disposed on the outer peripheral surface of the first port 21, and the L-shaped groove is formed by recessing inward from the outer peripheral surface of the first port 21.
[0060] More preferably, the L-shaped groove includes an inlet portion 114, which is elongated and extends to the edge of the first port 113. The inlet portion 114 extends along the length direction of the vibration sound wave generating device 1.
[0061] More preferably, one end of the latching part 115 is connected to the end of the entrance part 114 that is away from the edge of the first port 113, and the latching part 115 intersects with the entrance part 114 so that the two are internally connected.
[0062] It should be noted that the groove depths of the inlet 114 and the latch 115 can be the same or different. Users can set them according to their needs, and no specific limitation is made here.
[0063] Preferably, the locking block 23 is disposed on the inner peripheral surface of the second opening 22, protruding from the inner peripheral surface of the second opening 22. The number of locking blocks 23 is the same as the number of L-shaped slots and corresponds one-to-one, so that each locking block 23 can be locked in its corresponding L-shaped slot.
[0064] More preferably, when the bite 2 is installed on the first port 113, the locking block 23 passes through the inlet 114 and reaches the bottom of the inlet 114. Then the bite 2 is rotated so that the locking block 23 rotates into the locking part 115 and is locked in the locking part 115, so as to realize the locking connection between the bite 2 and the first port 113.
[0065] Furthermore, the locking block 23 and the latching part 115 are fitted together to achieve a stable connection between the two. Specifically, the ratio of the outer diameter of the first port 113 to the inner diameter of the second opening 22 is any value between 0.95 and 1.05, such as 0.95, 0.96, 0.97, 0.98, 0.99, 1, 1.01, 1.02, 1.03, 1.04, 1.05, etc. This prevents the gap from being too large, which would cause the bite 2 and the outer shell 11 to wobble, resulting in structural instability and detachment. On the other hand, it prevents the interference from being too large, which would cause the connection between the two to be too tight and unable to be disassembled, or prevent the first port 113 from being able to be inserted into the second opening 22, resulting in latching failure.
[0066] It should be noted that the above-mentioned snap-fit connection allows the mouthpiece 2 and the vibration sound wave generating device 1 to be easily disassembled for cleaning, ensuring hygiene during use; and the snap-fit connection provides a smooth transition, achieving a stable connection between the mouthpiece 2 and the vibration sound wave generating device 1, preventing them from easily separating, shaking, or failing to engage.
[0067] In one embodiment, the inlet portion 114 and the latching portion 115 are arranged perpendicularly, such as... Figure 6 As shown.
[0068] Preferably, the inlet 114 and the latching part 115 are arranged perpendicularly, so that when the latching block 23 passes through the inlet 114 and is latched in the latching part 115, it plays an effective latching role, preventing it from detaching along the length direction of the vibration sound wave generating device 1, so that the bite 2 and the vibration sound wave generating device 1 are firmly connected.
[0069] It should be noted that in other embodiments, the entrance portion 114 and the latch portion 115 may also be set at an acute angle or an obtuse angle, etc., and the user can set them according to their needs. No specific limitation is made here.
[0070] In one embodiment, the lower end of the card block 23 is hemispherical, such as... Figure 2 and Figure 5 As shown.
[0071] Preferably, the lower end of the locking block 23 is hemispherical, so that the locking block 23 can be disengaged from the latching part 115 by slightly rotating the bite 2, which facilitates disassembly and reduces damage to the outer surface of the first port 113.
[0072] It should be noted that in other embodiments, the lower end of the card block 23 may also be conical or other shapes, which are not specifically limited here.
[0073] In one embodiment, the latching part 115 is provided with a bottom groove, and the latching block 23 is latched in the bottom groove, such as... Figure 2 and Figure 6 As shown.
[0074] Preferably, the bottom surface of the latching part 115 is provided with a bottom groove, which can be cylindrical, hemispherical, etc., and is not specifically limited here.
[0075] More preferably, when the locking block 23 is engaged in the latching part 115, the lower end of the locking block 23 is received in the bottom groove to achieve a latching connection with the locking block 23, effectively preventing the locking block 23 from shaking in the latching part 115.
[0076] It should be noted that the hemispherical design of the lower end of the locking block 23 allows the bottom of the locking block 23 to be disengaged from the bottom groove by slightly rotating the bite 2 when it is inserted into the bottom groove, which makes it easy to remove the bite 2.
[0077] More preferably, the bottom groove can be set in the middle of the buckle part 115, or at one end of the buckle part 115, etc. The user can set it according to his or her needs, and no specific limitation is made here.
[0078] In one embodiment, the first port 113 is the end of the housing 11, such as... Figure 1 As shown.
[0079] Preferably, the first port 113 is one end of the outer shell 11 along its length, which facilitates connection with the second opening 22 of the mouthpiece 2, so that the first cavity 18 communicates with the first opening 21.
[0080] More preferably, the shape of the first port 113 is adapted to the shape of the outer shell 1. For example, when the outer shell 11 is a cylinder, the first port 113 is also a cylinder. It can be set as needed, and no specific limitation is made here.
[0081] In one embodiment, the first port 113' protrudes from the end face of the housing 11 and is disposed around the first cavity 18, such as... Figure 9 As shown.
[0082] Preferably, the first port 113' is disposed on the end face of the housing 11 and protrudes from the end face of the housing 11 so as to connect with the first opening 21.
[0083] More preferably, the first port 113' is arranged around the port of the first cavity 18, so that the shape of the first port 113' is adapted to the shape of the first cavity 18, so that all the gas entering the first port 113' can flow into the first cavity 18, reducing the obstruction to the airflow and preventing airflow turbulence.
[0084] In one embodiment, the vibration sound wave generating device 1 includes a housing 11, a partition 12 disposed within the housing 11, a swing arm 13, and a valve 14 disposed on the swing arm 13. The partition 12 is used to divide the space within the housing 11 into a first cavity 18 and a second cavity 19. The partition 12 has a through hole 121 connecting the first cavity 18 and the second cavity 19. The swing arm 13 is used to swing within the housing 11 to periodically swing to a first position and a second position. When the swing arm 13 swings to the first position, the valve 14 blocks the through hole 121, and when the swing arm 13 swings to the second position, the valve 14 does not block the through hole 121. Figure 1 As shown.
[0085] Preferably, the outer shell 1 can be cylindrical or rectangular, etc. In this embodiment, the outer shell 1 is cylindrical; the first port 113 is provided at one end of the outer shell 1, such as the end in the length direction, so as to connect with the bite nozzle 2.
[0086] More preferably, the partition 12 is disposed inside the outer shell 1 and is used to divide the space inside the outer shell 1 into a first cavity 18 and a second cavity 19. The first cavity 18 and the second cavity 19 are arranged radially along the outer shell 1. The first cavity 18 is connected to the first port 113, and the second cavity 19 is connected to the other port of the outer shell 1 to realize the flow of gas between the first cavity 18 and the second cavity 19. The partition 12 extends along the length direction of the outer shell 1 and is located between the first cavity 18 and the second cavity 19. The partition 12 is provided with a through hole 121 connecting the first cavity 18 and the second cavity 19, so that gas can be connected between the first cavity 18 and the second cavity 19 by passing through the protrusion 121.
[0087] Preferably, the swing arm 13 is oscillating within the housing 1. When the patient exhales or inhales, the swing arm 13 oscillates periodically back and forth under the action of airflow to generate vibrational sound waves. During periodic oscillation, the swing arm 13 can oscillate periodically to a first position and a second position. When the swing arm 13 oscillates to the first position, the valve 14 blocks the through hole 121, thereby sealing the first cavity 18 and the second cavity 19 and preventing gas from flowing between the two cavities. When the swing arm 13 oscillates to the second position, the valve 14 does not block the through hole 121, and gas can flow between the first cavity 18 and the second cavity 19 through the through hole 121.
[0088] It should be noted that the second position mentioned above refers to the position where the swing arm 13 swings to any position where the valve 14 does not block the through hole 121, and no specific limitation is made here.
[0089] Preferably, valve 14 is disposed on swing arm 13, valve 14 is disposed opposite to through hole 121, and the shape of valve 14 is adapted to the shape of through hole 121, so that when swing arm 13 swings to the first position, valve 14 blocks through hole 121 to block the flow of gas between first cavity 18 and second cavity 19.
[0090] It should be noted that the partition plate 12 is provided with a protrusion 122, and the through hole 121 penetrates the upper and lower surfaces of the protrusion 122. The protrusion 122 can better guide the valve 14 to block the through hole 121 and improve the overall stability of operation.
[0091] In one embodiment, the first cavity 18 is an air inlet cavity and the second cavity 19 is an air outlet cavity, such as... Figure 1 As shown.
