Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a treatment device for rhinitis and sinusitis. Background Art

[0002] The nasal cavity and sinuses are located below the skull, above the throat and mouth, and between the two eye sockets. Lesions in the nasal cavity and sinuses often spread to nearby tissues, thus causing various complications. Since the sinuses are cavities within the bones around the nasal cavity, sinusitis is often caused by the narrowness of the sinus passages, which hinders the ventilation and drainage of the sinuses, leading to infection. As a result, the infected sinuses are difficult to cure due to the narrow sinus passages, and sinusitis will further spread to the nasal cavity, forming rhinitis. Existing drugs for treating sinusitis and rhinitis usually have difficulty reaching the lesion site. Although the atomization treatment method can directly administer drugs to the lesion site, due to the often blocked sinuses, it is difficult to deliver the drugs to the lesion site. Summary of the Invention

[0003] This application proposes a treatment device for rhinitis and sinusitis to solve the above problems.

[0004] The embodiments of this application achieve the above objectives through the following technical solutions.

[0005] A treatment device for rhinitis and sinusitis includes a housing, a partition board, a vibration unit, and a cover body. The housing has an inner cavity, as well as an air inlet end and an air outlet end that communicate with the inner cavity. The partition board is disposed inside the housing, separating the inner cavity into a first chamber and a second chamber. The partition board is provided with a through hole. The vibration unit is movably disposed at the through hole. The vibration unit is used to generate vibration sound waves with a frequency range of 20 - 300 Hz under the action of the working air flow. Among them, the working air flow is generated when the user exhales into the air inlet end or inhales from the air outlet end. The working air flow enters the second chamber from the first chamber through the through hole. The cover body is used to connect between the air inlet end and the nasal cavity, or between the air outlet end and the nasal cavity, to provide the working air flow to the housing.

[0006] In some embodiments, the vibration unit includes a bracket, a swing arm, and a switching valve. The bracket is fixedly arranged relative to the housing. The first end of the swing arm is close to the air inlet end and is rotatably connected to the bracket. The second end of the swing arm is close to the air outlet end. The switching valve connects the first end and the second end and is located within the through hole. The switching valve periodically rotates around the bracket to open the through hole when the air pressure in the first chamber is greater than that in the second chamber, and resets to the through hole under the restoring force of the swing arm to generate vibration sound waves.

[0007] In some embodiments, when exhaling, the periodic pressure change range in the first chamber is 0 - 90 cmH2O; when inhaling, the periodic pressure change range in the second chamber is -90 - 0 cmH2O.

[0008] In some embodiments, when the rhinitis and sinusitis treatment device generates vibration sound waves only through exhalation, the volume range of the first chamber is 5 cm 3 ~25 cm 3 ; when the rhinitis and sinusitis treatment device generates vibration sound waves only through inhalation, the volume range of the second chamber is 5 cm 3 ~25 cm 3 ; when the rhinitis and sinusitis treatment device is adapted to generate vibration sound waves both through exhalation and through inhalation, the volume range of the first chamber is 5 cm 3 ~25 cm 3 and the volume range of the second chamber is 5 cm 3 ~25 cm 3 .

[0009] In some embodiments, the rhinitis and sinusitis treatment device further includes a nebulizer connection part which is directly communicated with the first chamber and is used for connecting a nebulizer.

[0010] In some embodiments, the nebulizer connection part is provided with a nebulizer liquid channel. The nebulizer connection part includes a nebulizer one-way valve which is arranged in the nebulizer liquid channel. When the air pressure in the first chamber is less than the air pressure in the nebulizer liquid channel, the nebulizer one-way valve opens the nebulizer liquid channel.

[0011] In some embodiments, the rhinitis and sinusitis treatment device further includes an oxygen connection part which is communicated with the first chamber and is used for connecting an oxygen supply device.

[0012] In some embodiments, the rhinitis and sinusitis treatment device further includes a multi-channel connection part which is provided with a first interface, a second interface and a third interface. The first interface is communicated with the cover body, the second interface is used for being communicated with a nebulizer, and the third interface is used for selectively communicating with the housing at the air inlet end or the air outlet end.

[0013] In some embodiments, the central axis of the cover body coincides with or is substantially coincident with and deviates from the ground, and there is an included angle between the central axis of the cover body and the center of gravity line of the rhinitis and sinusitis treatment device. The range of the included angle is 20° to 70°.

[0014] In some embodiments, the rhinitis and sinusitis treatment device further includes an extension tube which is used for communicating the housing and the cover body.

[0015] Compared with the prior art, when a patient uses the rhinitis and sinusitis treatment device provided by the present application, the nasal cavity and the nasal sinus cavity can be opened through vibration sound waves, which helps to exercise the nasal-related muscles and improve the atomization drug delivery effect, so as to relieve or treat rhinitis and sinusitis.

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. And based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0038] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0039] 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 ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 3 , an apparatus 100 for treating rhinitis and sinusitis according to an embodiment of the present application includes a housing 1, a partition plate 2, a vibration unit 3, and a cover body 7 (see Figure 6 ); the housing 1 has an inner cavity 10, an air inlet end 11 and an air outlet end 12 communicating with the inner cavity 10; the partition plate 2 is disposed in the housing 1 to isolate the inner cavity 10 into a first cavity 101 and a second cavity 102, and the partition plate 2 is provided with a through hole 20; the vibration unit 3 is movably disposed at the through hole 20, and the vibration unit 3 is configured to generate vibration sound waves with a frequency range of 20 - 300 Hz under the action of the working air flow, wherein the working air flow is generated when the user exhales through the air inlet end 11 or inhales through the air outlet end 12, and the working air flow enters the second cavity 102 from the first cavity 101 through the through hole 20. The cover body 7 is used to connect between the air inlet end 11 and the nasal cavity or between the air outlet end 12 and the nasal cavity to provide the working air flow to the housing 1.

[0041] The housing 1 is generally a hollow cylindrical structure, and the hollow area forms the inner cavity 10. On the Figure 2 shown left side is the air inlet end 11 of the apparatus 100 for treating rhinitis and sinusitis, and on the Figure 2 shown right side is the air outlet end 12 of the apparatus 100 for treating rhinitis and sinusitis. The air inlet end 11 and the air outlet end 12 do not specifically refer to a certain structure, but only indicate directions. The on-off valve 32 of the apparatus 100 for treating rhinitis and sinusitis provided in this embodiment opens the through hole 20 and allows the 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 flow direction of the working air flow is fixed.

[0042] The air inlet end 11 is provided with an air inlet 13, and the air outlet end 12 is provided with an air outlet 14. The working air flow can only flow in from the air inlet 13 and can only flow out from the air outlet 14. The air inlet 13 is directly communicated with the first cavity 101, and the air outlet 14 is directly communicated with the second cavity 102. Compared with the situation where some snore treatment devices have multiple air outlets at the air outlet 14, providing only one air outlet 14 is beneficial to maintaining the pressure in the second cavity 102 and facilitating inhalation training from the second end 12.

[0043] Please refer to Figure 2, in addition to the wall 15 that forms the contour, the housing 1 may also be provided with a plurality of support walls 16 in the inner cavity 10. These support walls 16 can assist the partition plate 2 in partitioning 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 shields a part 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.

[0044] Please refer to Figure 2 and Figure 3 , the partition plate 2 is a plate-like structure with a relatively thin thickness and is connected between the radial side wall 161 and the bottom wall 162, thereby dividing the inner cavity 10 into a first cavity 101 and a first cavity 101 that are roughly stacked up and down. 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 separately manufactured and then fixedly connected, such as by welding, snap connection, etc.

[0045] The partition plate 2 is provided with a through hole 20, and the axis of the through hole 20 is perpendicular or substantially perpendicular to the partition plate 2. The height of the through hole 20 can be equal to the thickness of the partition plate 2, that is, the through hole 20 is directly formed by opening a hole in the partition plate 2.

[0046] In this embodiment, the partition plate 2 includes a base plate 21 and an extension portion 22 extending from the base plate 21 towards the first cavity 101. The extension portion 22 and the base plate 21 can be an integral structure. The base plate 21 can be a sheet-like structure. At the position where an opening is required, the base plate 21 extends outwards to form the extension portion 22. The extension portion 22 is frustum-shaped, and the through hole 20 penetrates through the extension portion 22. The central axis is perpendicular to the base plate 21, and the through hole 20 is a truncated conical shape. The conical shape is more helpful for guiding the air flow in the first cavity 101 into the first cavity 101.

[0047] Forming the through hole 20 directly on the partition plate 2 simplifies the internal structure compared to additionally connecting a structure for placing the switching valve 32 on the partition plate 2, reduces the assembly error between other structures and the partition plate 2, improves the fitting accuracy between the structures, and can also ensure the sealing effect.

[0048] After assembly, the extension portion 22 extends into the first cavity 101 relative to the base plate 21, and there is no need to separately set aside space for the extension portion 22 outside the first cavity 101, thereby reducing the height of the rhinitis and sinusitis treatment device 100 as a whole 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.

[0049] In some embodiments, the vibration unit 3 may be a metal shrapnel attached to the through hole 20 of the isolation plate 2 facing the second cavity 102. One end of it is fixed to the isolation plate 2, while the other end is free. When there is no working air flow entering the first cavity 101, the metal shrapnel fits against the isolation plate 2 to close or semi-close the through hole 20. When the working air flow rushes from the first cavity 101 to the second cavity 102, the metal shrapnel vibrates, opens the through hole 20, and periodically vibrates under the continuous action of the working air flow, thereby generating vibration sound waves within a specific frequency range.

[0050] In this embodiment, the vibration unit 3 includes a bracket 30, a swing arm 31, and a switch valve 32. The bracket 30 is fixedly arranged relative to the housing 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. The switch valve 32 connects the first end 311 and the second end 312 and is located within the through hole 20. The switch valve 32 periodically rotates around the bracket 30 along with the swing arm 31 to open the through hole 20 when the air pressure in the first cavity 101 is greater than that in the first cavity 101, and resets to the through hole 20 under the restoring force of the swing arm 31, thereby generating vibration sound waves. During this period, the working air flow enters the first cavity 101 through the air inlet end 11, flows into the first cavity 101 through the through hole 20, and then flows out from the air outlet end 12; the frequency range of the vibration sound waves is 20 - 300 Hz; the working air flow is an exhalation air flow or an inhalation air flow, where the exhalation air flow is the air flow inhaled into the air inlet end 11, and the inhalation air flow is the air flow sucked out at the air outlet end 12.

[0051] The bracket 30 of the vibration unit 3 is fixed to the isolation plate 2. The bracket 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 bracket 30 is fixed relative to the housing 1 differently. In other embodiments, the bracket 30 can be fixed to the inner wall 513 of the housing 1. In short, as long as the bracket 30 is fixedly arranged relative to the housing 1.

[0052] The swing arm 31 is a plate body with an arbitrary shape. When placed, its length direction is arranged along the air inlet end 11 and the air outlet end 12. The swing arm 31 includes opposite first end 311 and second end 312. The first end 311 is close to the air inlet end 11, and the second end 312 is close to the air outlet end 12. The swing arm 31 can be rotatably connected to the bracket 30 through one or two rotating shafts.

[0053] The switch valve 32 is arranged close to the second end 312. The shape of the switch valve 32 matches the shape of the air inlet 13 and can completely close or substantially close the air inlet 13.

[0054] In this embodiment, the through hole 20 is a truncated cone, and the switch valve 32 includes a conical portion extending in the length direction away from the swing arm 31 to cooperate with the inner wall 513 of the extension portion 22.

[0055] In some embodiments, the switching valve 32 is flexibly connected to the swing arm 31. The switching valve 32 is disposed on one side of the swing arm 31 close to the second end 312 and forms a flexible connection with the swing arm 31. That is, it is connected through a flexible material or a spring structure.

[0056] The vibration unit 3 provided in this embodiment has an asymmetric hinge motion structure. Taking the bracket 30 as the boundary, the switching valve 32 is located on the side from the bracket 30 to the second end 312. Since the switching valve 32 drives the swing arm 31 to rotate relative to the bracket 30, the distance from the bracket 30 to the second end 312 is the power arm of the swing arm 31. Correspondingly, the distance from the bracket 30 to the first end 311 is the resistance arm of the swing arm 31. The asymmetric hinge motion structure means that the power arm is longer than the resistance arm, which makes the structure of the entire rhinitis and sinusitis treatment device 100 more compact. In other embodiments, the power arm can also be substantially equal in length to the resistance arm to form a symmetric hinge motion structure.

[0057] Whether it is for exhalation training or inhalation training, the working air flow enters the first chamber 101 from the air inlet end 11. The working air flow refers to the air flow actively provided by the user. It can be provided by the user exhaling into the housing 1 from the air inlet end 11, or it can be provided by the user inhaling air through the housing 1 from the air outlet end 12. Whether it is the exhaled air flow or the inhaled air flow, the flow direction in the housing 1 is the same, and the principle of vibration is the same, and both belong to the working air flow.

[0058] Before the working air flow reaches the switching valve 32, the switching valve 32 completely closes the through hole 20 or substantially closes the through hole 20. Before the working air flow enters the first chamber 101 and before it enters the first chamber 101, whether the switching valve 32 completely closes the through hole 20 or does not completely close the through hole 20, the pressure in the first chamber 101 is greater than the pressure in the first chamber 101. Therefore, relatively speaking, the first chamber 101 is the high-pressure chamber and the first chamber 101 is the low-pressure chamber. Under the action of the pressure difference between the two chambers, the switching valve 32 moves away from the through hole 20, causing the through hole 20 to open, and the working air flow enters the first chamber 101 from the first chamber 101 through the through hole 20.

[0059] As mentioned above, "completely closing the through hole 20" by the switching valve 32 means that the switching valve 32 seals the through hole 20, and "substantially closing the through hole 20" means that the switching valve 32 does not completely seal the through hole 20, but does not completely open the through hole 20 either. That is, compared with the case of completely sealing the through hole 20, it does not have to reach the completely sealed state, as long as it can be in a substantially sealed state, so that a pressure difference is generated between the first chamber 101 and the first chamber 101, enabling the switching valve 32 to move and open the through hole 20.

[0060] After the through-hole 20 is opened, the switching valve 32 resets under the restoring force of the swing arm 31, completely closing or substantially closing the through-hole 20, and the working air flow flows out from the air outlet end 12. The switching valve 32 is arranged on the swing arm 31, and the swing arm 31 rotates relative to the bracket 30 due to the movement of the switching valve 32. After the swing arm 31 rotates, it rotates reversely under the action of the restoring force provided by the resistance arm, so that the switching valve 32 resets to the through-hole 20, completely closing or substantially closing the through-hole 20. The working air flow is discharged from the first chamber 101 through the air outlet end 12 out of the housing 1. In this embodiment, during the rotation of the swing arm 31, the rebound force generated by the collision of the first end 311 (on the side of the resistance arm) with the partition plate 2 causes the swing arm 31 to rotate reversely.

[0061] The user continuously provides the working air flow. When the next working air flow enters the first chamber 101, the vibration unit 3 repeats the above operations, the pressure difference between the first chamber 101 and the first chamber 101 increases again, and the switching valve 32 opens again. In this way, the vibration unit 3 generates vibration sound waves. In this embodiment, the frequency range of the vibration sound waves is 20 - 300 Hz. The vibration sound waves within this frequency range can cause the vibration of the nasal cavity-related muscles. Therefore, it can relieve or treat snoring, rhinitis, and sinusitis caused by the weakness of the nasal muscle group.

[0062] The working air flow can be provided in the form of nasal inhalation or nasal exhalation through the cover body 7. The cover body 7 can fit around the nose or around the mouth and nose, as long as it can allow the nose to provide the working air flow.

[0063] Please refer to Figure 2 , in this embodiment, the air inlet 13 is open, and the air outlet 14 is provided with a ventilation cover 17. The ventilation cover 17 is in a plate-like structure, arranged at the air outlet 14, and the ventilation cover 17 is provided with a plurality of ventilation holes. The number, shape, and size of the ventilation holes are not limited, as long as the air flow can be discharged. Further, the air outlet cross-sectional area can be adjusted by adjusting the number, shape, and size of the ventilation holes.

[0064] Specifically, in this embodiment, the intake cross-sectional area is approximately equal to the area of the air inlet 13. If there is no ventilation cover 17 and the thickness of the housing 1 is uniform everywhere, that is, the area of the air outlet 14 is basically the same as the area of the air inlet 13, so that the air outlet cross-sectional area is basically equal to the intake cross-sectional area. If the ventilation cover 17 is provided, the air outlet cross-sectional area is smaller than the intake cross-sectional area.

[0065] In other embodiments, if the area of the air inlet 13 is basically the same as the area of the air outlet 14, it can also be that a ventilation cover 17 is provided at the air inlet 13 and no ventilation cover 17 is provided at the air outlet 14, so that the intake cross-sectional area is smaller than the air outlet cross-sectional area.

[0066] In other embodiments, the intake cross-sectional area and the outlet cross-sectional area can also be changed by adjusting the diameter of the air inlet 13 and the diameter of the air outlet 14.

[0067] In other embodiments, the intake cross-sectional area and the outlet cross-sectional area can also be adjusted by comprehensively adjusting the diameter of the air inlet 13, the presence or absence of the ventilation cover 17 of the air inlet 13, the characteristics of the ventilation holes of the ventilation cover 17, the diameter of the air outlet 14, the presence or absence of the ventilation cover 17 of the air outlet 14, and the characteristics of the ventilation holes, so as to adjust the pressure of the first chamber 101 and the first chamber 101 as needed.

[0068] In some embodiments, if the rhinitis and sinusitis treatment device 100 is only used for nose exhalation, the intake cross-sectional area can be set to be smaller than the outlet cross-sectional area, so that the exhaled air flow can quickly fill the first chamber 101 and rapidly increase the pressure in the first chamber 101, improving the vibration efficiency. At the same time, the relatively large outlet cross-sectional area can quickly discharge the gas in the first chamber 101, avoiding the formation of eddy currents caused by the gas staying in the first chamber 101 and affecting the reciprocating swing of the swing arm 31.

[0069] In some embodiments, if the rhinitis and sinusitis treatment device 100 is only used for nose inhalation, the intake cross-sectional area can be set to be larger than the outlet cross-sectional area, which helps to supplement the air flow into the first chamber 101 as quickly as possible by the external atmospheric pressure during inhalation, ensuring a stable pressure difference is formed between the first chamber 101 and the first chamber 101, and enabling the switching valve 32 to switch stably.

[0070] In some embodiments, if the rhinitis and sinusitis treatment device 100 is used for both nose exhalation training and nose inhalation training, the intake cross-sectional area can be set to be equal to the outlet cross-sectional area, but it can also be set to be unequal. The size relationship between the outlet cross-sectional area and the intake cross-sectional area does not affect the basic functions of the rhinitis and sinusitis treatment device 100 provided in this embodiment.

[0071] Please refer to Figure 2, in some embodiments, the rhinitis and sinusitis treatment device 100 further includes a resistance unit 4. The resistance unit 4 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 opposite to the first magnetic member 41 within the housing 1. The magnitude of the magnetic force between the first magnetic member 41 and the second magnetic member 42 can be preset, so that the switching valve 32 is reset into the through hole 20 and the through hole 20 is closed through the magnetic attraction between the two. At the same time, a certain training resistance can be provided. That is, the user needs to provide a larger working air flow to open the switching valve 32, so as to achieve a better effect of exercising the expiratory muscles or the inspiratory muscles. Set the suction force between the first magnetic member 41 and the second magnetic member 42 as F1, the restoring force provided by the resistance arm of the swing arm 31 as F2, and the gravity of the swing arm 31 itself as F3. The torques acting on the swing arm 31 by the suction force F1, the restoring force F2, and the gravity F3 are M1, M2, and M3 respectively. Then, during the resetting process of the switching valve 32, it is always M1 + M2 > M3 to ensure the smooth resetting of the switching valve 32. The frequency of the vibration sound wave can be adjusted by adjusting the gravity of the swing arm 31 and the resistance of the resistance unit 4.

[0072] When the working air flow is provided by the nasal cavity, the frequency range of the vibration sound wave is 90 - 210 Hz. The vibration sound wave within this frequency range will cause obvious vibrations in the nasopharynx, and has obvious effects on apnea or snoring caused by weak nasal muscle groups and adenoid hypertrophy, as well as opening the nasal cavity passage and the sinus cavity passage.

[0073] In some embodiments, during exhalation, the periodic pressure change range of the first chamber 101 is 0 - 90 cmH2O; during inhalation, the periodic pressure change range of the second chamber 102 is -90 - 0 cmH2O. This pressure change range can cause more obvious vibrations in the relevant muscle groups, so as to achieve the technical effects of the present application.

[0074] In some embodiments, by adjusting the resistance of the switching valve 32, during exhalation, the frequency of the pressure change of the first chamber 101 is 20 - 300 Hz; during inhalation, the frequency of the pressure change of the second chamber 102 is 20 - 300 Hz, so that the relevant muscle groups vibrate at a preset frequency, achieving a better treatment and exercise effect.

[0075] In some embodiments, when the exhalation flow rate is constant, the smaller the volume of the first chamber 101, the greater the pressure of the first chamber 101. From another perspective, the smaller the volume of the first chamber 101, when the exhalation flow rate is constant, the shorter the time taken to reach the same pressure. Therefore, when the rhinitis and sinusitis treatment device 100 generates vibration sound waves only through exhalation, the volume range of the first chamber 101 is set to 5 - 25 cm 3, it can make the pressure change in the first chamber 101 proceed at a set frequency, ensuring frequency stability.

[0076] In some embodiments, 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. From another perspective, the smaller the volume of the second chamber 102, when the inhalation flow rate is constant, the shorter the time taken to reach the same pressure. Therefore, when the rhinitis and sinusitis treatment device 100 generates vibration sound waves only through inhalation, the volume range of the second chamber 102 is set to 5 - 25 cm 3 , it can make the pressure change in the second chamber 102 proceed at a set frequency, ensuring frequency stability.

[0077] In some embodiments, when the rhinitis and sinusitis treatment device 100 is adapted to generate vibration sound waves through exhalation and also through inhalation, considering the above-mentioned situations of using exhalation alone and inhalation alone, the volume range of the first chamber 101 can be set to 5 cm 3 ~25 cm 3 , and the volume range of the second chamber 102 is 5 cm 3 ~25 cm 3 .

[0078] Please refer to Figure 4 , the rhinitis and sinusitis treatment device 200 provided by another embodiment of the present application further includes a nebulizer connection part 8. The nebulizer connection part 8 is directly communicated with the first chamber 101 and is used to connect a nebulizer (not shown in the figure).

[0079] During exhalation, the atomized liquid supplied by the nebulizer can be inhaled into the nasal cavity when the user breathes. During inhalation, the atomized liquid supplied by the nebulizer can be inhaled into the nasal cavity along the flow of the working air flow. Thus, while the nasal cavity and the sinus cavity are opened under the action of the vibration sound waves, external nebulizer administration can be obtained, improving the treatment effect.

[0080] In some embodiments, the nebulizer connection part 8 is provided with an atomized liquid channel 80. The nebulizer connection part 8 includes an atomized liquid one-way valve 81. The atomized liquid one-way valve 81 is arranged in the atomized liquid channel 80. When the air pressure in the first chamber 101 is less than the air pressure in the atomized liquid channel 80, the atomized liquid one-way valve 81 opens the atomized liquid channel 80, thereby further improving the drug administration effect and efficiency.

[0081] Specifically, the atomizing one-way valve 81 may include a valve film 810 and a stop portion 811. The stop portion 811 stops at the atomizing liquid channel 80 and is close to the side of the atomizing liquid channel 80. The valve film 810 is movably disposed on the stop portion 811 and is close to the first chamber 101. The stop portion 811 is provided with a through hole 8110. When the air pressure in the first chamber 101 is greater than or equal to the air pressure in the atomizing liquid channel 80, the valve film 810 fits against the stop portion 811 and closes the through hole 8110. When the air pressure in the first chamber 101 is less than the air pressure in the atomizing liquid channel 80, the valve film 810 opens toward the first chamber 101, the through hole 8110 opens, and the atomizing liquid enters the first chamber 101.

[0082] During nasal inhalation, the cover body 7 is connected to the air outlet end 12. During inhalation, the pressure in the second chamber 102 decreases, forming a pressure difference with the first chamber 101, thereby opening the switch valve 32. During the process of opening the switch valve 32, the working air flow flows from the first chamber 101 to the air outlet end 12, causing the pressure in the first chamber 101 to decrease. At this time, the pressure in the atomizing liquid channel 80 is greater than the pressure in the first chamber 101, and the valve film 810 opens, forming an air flow channel from the atomizer, the first chamber 101, the second chamber 102 to the nasal cavity. The vibration sound wave formed by the vibration unit 3 causes the vibration of the nasal cavity. At the same time, the atomization generated by the atomizer enters the nasal cavity along with the air flow.

[0083] The vibration of the nasal cavity causes the sinus passage to be unable to maintain its narrow state. When the vibration sound wave is transmitted to the sinus, the pressure in the sinus cavity also changes with the vibration. When the pressure in the sinus cavity is less than the pressure in the nasal cavity, the atomized drug enters the sinus cavity along with the air flow, thereby achieving the effect of treating rhinitis. Moreover, after a period of nasal vibration exercise, the nasal muscles tighten and the nasal cavity becomes unobstructed, and snoring caused by nasal stenosis can also be solved.

[0084] During nasal exhalation, the cover body 7 is connected to the air inlet end 11. During exhalation, under the control of the user's muscle group, the pressure in the entire nasal cavity and sinus cavity increases. Among them, the air flow in the sinus cavity can open the sinus passage, and under the action of the vibration sound wave, the sinus passage is further opened. When the user performs ventilation (inhaling at the air inlet end 11), the air pressure in the first chamber 101 is less than the air pressure in the atomizing liquid channel 80, the valve film 810 opens, and the atomizing liquid quickly flows to the nasal cavity and sinus cavity, thereby achieving the effect of treating rhinitis and sinusitis.

[0085] Please refer to Figure 5 , in some embodiments, the rhinitis and sinusitis treatment device 300 further includes an oxygen connection portion 91. The oxygen connection portion 91 is communicated with the first chamber 101 and is used to connect an oxygen supply device. There are at least two ways for the oxygen connection portion 91 to be communicated with the first chamber 101. The first one is to separately open an interface and directly communicate with the first chamber 101. The second one is as Figure 5As shown, it is connected to the first chamber 101 through the atomized liquid channel 80. This depends on the specific structure of the atomization connection part 8. For example, as Figure 5 shown, the atomized liquid channel 80 of the atomization connection part 8 includes a small channel and a large channel. The small channel is separately connected to the atomizer, and the large channel can be shared with the oxygen connection part 91. At this time, both the atomized liquid and oxygen can enter the nasal cavity. In addition to treating rhinitis and sinusitis, for users with poor respiratory function, it can also synchronously increase the oxygen intake and effectively maintain the cardiopulmonary function of the user.

[0086] Please refer to Figure 6 , in some embodiments, the rhinitis and sinusitis treatment device 400 further includes a multi-channel connection part 82. The multi-channel connection part 82 is provided with a first interface 821, a second interface 822, and a third interface 823. The first interface 821 is connected to the cover body 7, the second interface 822 is used to be connected to the atomizer 9, and the third interface 823 is used to selectively connect to the housing 1 at the air inlet end 11 or the air outlet end 12.

[0087] Whether inhaling or exhaling, the atomizer 9 is always connected to the cover body 7 through the second interface 822, the first interface 821 of the multi-channel connection part 82, so that the degree of the atomized liquid inhaled into the nasal cavity can be improved.

[0088] Please refer to Figure 7 , in some embodiments, the central axis of the cover body 7 coincides with or is substantially coincident with the central axis of the housing 1 and deviates from the ground (i.e., faces the sky). There is an included angle θ between the central axis of the cover body 7 and the center of gravity line of the rhinitis and sinusitis treatment device 100. The range of the included angle θ is 20° to 70°. In this way, since the density of the atomized liquid is less than the density of air, the atomized liquid floats upward and further floats in the direction of the cover body 7 under the action of suction. Therefore, especially when inhaling through the nose, the atomized liquid can be maximally inhaled, and the atomization treatment effect can be improved.

[0089] Please refer to Figure 8 , in some embodiments, the rhinitis and sinusitis treatment device 100 further includes an extension tube 23. The extension tube 23 is used to connect the housing 1 and the cover body 7. When the rhinitis and sinusitis treatment device 100 includes a multi-channel connection part 82, the extension tube 23 can be connected to the third interface 823. At one end of the atomized liquid close to the cover body 7, when the atomized liquid enters the vibration unit 3, it may form a medicinal liquid and have viscosity. Therefore, it may affect the resistance to open the switching valve 32. When exhaling, the atomized liquid on the nasal cavity or the port close to the nasal cavity flows towards the vibration unit 3. If there is an extension tube 23, when the atomized liquid passes through the extension tube 23, the human mucus and the atomized liquid condense in the extension tube 23 first, thereby reducing the retention of the human mucus and the atomized liquid in the housing 1 and reducing the influence on the vibration unit 3.

[0090] Please refer to Figure 9, in one embodiment, the air outlet 14 is provided with a ventilation cover 17. The size of the ventilation cover 17 matches the inner diameter of the air outlet 14. The ventilation cover 17 is provided with ventilation holes, which is beneficial for exhaust. And Figure 2 compared with the housing 1 in

[0091] Please refer to Figure 10 , in another embodiment, in addition to setting the ventilation cover 17 at the air outlet 14, a similar ventilation cover 17 can also be set at the air inlet 13.

[0092] Please refer to Figure 11 , in yet another embodiment, the ventilation covers 17 at both the air inlet 13 and the air outlet 14 are cancelled. In this way, the intake cross-sectional area and the exhaust cross-sectional area can be maximized respectively, improving the efficiency of exhalation and inhalation. At the same time, the overall weight of the instrument can be reduced, making it easier to carry.

[0093] Please refer to Figure 12 and Figure 13 , in this embodiment, one end of the cover body 7 is a sealing surface 70, and the other end is a connecting portion 71.

[0094] The sealing surface 70 is made of a soft material, such as silica gel, TPU, etc., and is mainly used to seal the nasal cavity. The connecting portion 71 can be connected to the air inlet end 11 of the housing 1. By setting different shapes of the sealing surface 70, it can be fitted and sealed with the nasal cavity or the nose and mouth. For example, the shape of the sealing surface 70 can be selected as nearly triangular to conform to the nasal cavity contour or the nose and mouth contour of the human body.

[0095] 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. In this way, it can be connected to the air inlet end 11 or the air outlet end 12 provided with a positioning post.

[0096] Please refer to Figure 14 , in another embodiment, the connecting portion 71' is provided with a first peripheral wall 721 and a second peripheral wall 722 directly connected to the first peripheral wall 721 to form a stepped connecting portion. The second peripheral wall 722 is closer to the free end where the non-sealing surface of the cover body 7 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 one with a smaller inner diameter among the air inlet end 11 and the air outlet end 12, and the second peripheral wall 722 is used to connect to the one with a larger inner diameter among the air inlet end 11 and the air outlet end 12. In this way, the same cover body 7 can be connected to both the air outlet end 12 and the air inlet end 11, which is applicable to the case where the outer diameters of the air inlet end 11 and the air outlet end 12 of the housing 1 are different.

[0097] Please refer to Figures 15 to 20, in some embodiments, the cover body 7 includes a cover main body 75, an inhalation one-way valve 73, and / or an exhalation one-way valve 74. The inhalation one-way valve 73 is disposed on the cover main body 75 to assist inhalation, and the exhalation one-way valve 74 is disposed on the cover main body 75 to assist exhalation.

[0098] The cover main body 75 refers to a cover-shaped structure, on which the inhalation one-way valve 73 or the exhalation one-way valve 74 can be provided, or both the inhalation one-way valve 73 and the exhalation one-way valve 74 are provided. Among them, the number of various types of one-way valves is not limited.

[0099] Please refer to Figure 15 and Figure 16 , the inhalation one-way valve 73 is disposed on the cover main body 75. The inhalation one-way valve 73 includes a valve flap 730 and a stopper 731. The valve flap 730 is disposed below the stopper 731 and close to the sealing surface 70. During exhalation, the valve flap 730 is blocked by the stopper 731 to play a sealing role. During inhalation, the valve flap 730 can be opened to assist inhalation. When exhaling through the cover body 7, the inhalation one-way valve 73 closes; due to the existence of the inhalation one-way valve 73, the user can inhale through the cover body 7. During inhalation, the inhalation one-way valve 73 opens and provides an inhalation airflow in the opposite direction to the exhalation airflow direction, so that it is not necessary to remove the cover body 7 during inhalation and the user can directly inhale. For example, if nasal exhalation is performed using the cover body 7, it is not necessary to remove the cover body 7 and the user can directly nasal inhale, thereby improving the ventilation efficiency and the training efficiency.

[0100] Please refer to Figure 17 and Figure 18 , the exhalation one-way valve 74 is disposed on the cover main body 75. The exhalation one-way valve 74 includes a valve flap 740 and a stopper 741. The valve flap 740 is disposed above the stopper 741. During inhalation, the valve flap 740 is blocked by the stopper 741 to play a sealing role. During exhalation, the valve flap 740 can be opened to assist exhalation. When inhaling through the cover body 7, the exhalation one-way valve 74 closes; due to the existence of the exhalation one-way valve 74, the user can use the cover body 7 to exhale. During exhalation, the exhalation one-way valve 74 opens and provides an exhalation airflow in the opposite direction to the inhalation airflow direction, so that it is not necessary to remove the cover body 7 during exhalation and the user can directly exhale. For example, if nasal inhalation is performed using the cover body 7, it is not necessary to remove the cover body 7 and the user can directly nasal exhale, thereby improving the ventilation efficiency, avoiding problems such as dizziness and decreased metabolic efficiency caused by excessive retention of carbon dioxide in the body, and improving the training efficiency.

[0101] Please refer to Figure 19 and Figure 20, the cover 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 ventilation during exhalation / inhalation can be switched through one cover body 7. When using the cover body 7 for nasal inhalation training, seal the inhalation one-way valve 73 with the sealing cover 76 and open the sealing cover 76 of the exhalation one-way valve 74 to quickly ventilate. When using the cover body 7 for nasal exhalation training, seal the exhalation one-way valve 74 with the sealing cover 76 and open the sealing cover 76 of the inhalation one-way valve 73 to quickly ventilate.

[0102] When the cover body 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 that 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 can enable the user to quickly supplement oxygen. The average intake area of a person is 40 square millimeters to 57 square millimeters, so such a setting can ensure the normal inhalation level of the user.

[0103] Compared with the prior art, the patient can use the rhinitis and sinusitis treatment device 100 provided by the present application to open the nasal cavity and nasal sinus cavity through vibrating sound waves, which helps to exercise the nasal-related muscles and improve the atomization drug delivery effect, thereby relieving or treating rhinitis and sinusitis.

[0104] 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 foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
