Description

Technical Field

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

[0002] Breathing training is a method of enhancing respiratory function through specific training, primarily to improve respiratory function and enhance the efficiency of gas exchange. The beneficial effects of breathing training are primarily manifested in the following ways: First, it can effectively strengthen lung muscles and improve vital capacity; second, it helps improve blood circulation efficiency, promoting tissue oxygen supply and the removal of metabolic waste; third, for patients with chronic respiratory diseases, breathing training can help stabilize their condition and delay its progression; fourth, for athletes, it can further enhance endurance and competitive performance, while for the general population, it can enhance physical fitness, improve daily exercise performance, and improve quality of life.

[0003] Existing breathing training devices mainly include articulators and respirators. Since respirators usually have one-way ventilation, it becomes very difficult for users to inhale after exhaling, and they can only inhale through the nose. This makes it difficult for patients with rhinitis or who are not used to inhaling through the nose to use them. In addition, they need to constantly switch between the mouth and nose when breathing, which makes it very inconvenient to use. Summary of the Invention

[0004] In order to overcome the above technical problems, the present invention provides a breathing training device that can solve the above technical problems.

[0005] As conceived above, the technical solution adopted by the present invention is:

[0006] A breathing training device includes a main body and a valve fixed inside the main body. The main body is provided with a cavity located inside and for gas circulation, and a through hole arranged on its outer peripheral surface. The through hole is connected to the cavity. The valve faces the through hole to close the through hole during exhalation and deforms in a direction away from the through hole during inhalation to allow external gas to enter the cavity through the through hole.

[0007] The present invention has at least the following beneficial effects:

[0008] The breathing training device of the present invention is provided with a valve in the body, so that when the patient inhales, the valve is deformed to allow external air to enter the interior of the body through the through hole, without the need to inhale through the nasal cavity. When exhaling, the valve blocks the through hole to allow the gas to be discharged from the far end of the body, and then the entire breathing is achieved through the mouth. It is particularly convenient for patients with rhinitis or who are not accustomed to inhaling through the nose, and there is no need to switch between the mouth and the nose when breathing, which is easy to use.

[0029] The breathing training device provided by the present invention is described clearly and completely below with reference to the accompanying drawings. It is understood that the embodiments described are only some embodiments of the present invention, not all embodiments, and the present invention can be implemented in many other ways than those described herein.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in this specification are only for describing specific embodiments and are not intended to limit the present invention.

[0031] It should be noted that all directional indications in the embodiments of this specification are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout this specification, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0033] The technical solutions of the various embodiments of the present invention may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] In this specification, the axial direction refers to a direction parallel to the line connecting the distal center and the proximal center of the component; the radial direction refers to a direction perpendicular to the axial direction.

[0035] In one embodiment, the present invention discloses a breathing training device 100, comprising a body, a valve 3 fixed in the body, and a Figures 1 to 16 shown.

[0036] Preferably, the body is used for patient breathing training, with the proximal end of the body being engaged by the patient, and the distal end being used to achieve one-way gas flow, i.e., allowing only gas within the body cavity to flow from the proximal end to the distal end and out through the distal opening of the body, while preventing gas outside the body from flowing into the body cavity through the distal opening. Due to this structural arrangement, when the patient engages the proximal end of the body and exhales, the exhaled gas enters the body cavity, then flows toward the distal end and out through the distal opening, achieving exhalation training.

[0037] It should be noted that the proximal end is the end close to the operator, and the distal end is the end far away from the operator.

[0038] More preferably, the body is hollow, including a cavity located therein for gas flow, so as to achieve internal air flow. The body can be a cylinder, a cuboid or other geometric shapes, or an irregular geometric shape, etc., which is not specifically limited here.

[0039] More preferably, the proximal end of the body is flat so as to adapt to the shape of the mouth, facilitate the patient's mouth to bite, and achieve a more ideal sealing effect with the mouth.

[0040] Furthermore, preferably, the valve 3 is accommodated inside the body. In a natural state, the valve 3 may or may not be attached to the inner surface of the body, which is not specifically limited here.

[0041] It should be noted that the above-mentioned natural state is the state of the valve 3 when no force is applied.

[0042] Further preferably, the valve 3 may be circular, square or other shapes, etc., which are not specifically limited here. In this embodiment, the valve 3 is circular.

[0043] It should be noted that the main body is preferably made of silicone material, so that it can withstand high temperatures of up to 180 degrees Celsius for a long time and up to 210 degrees Celsius for a short time, which meets the general household disinfection method and does not produce harmful substances. It is economical, environmentally friendly and hygienic.

[0044] It is important to note that the thickness of the valve 3 is between 0.1 mm and 0.5 mm, which not only ensures its structural stability but also allows it to deform smoothly during inhalation to meet usage requirements. In this embodiment, the thickness of the valve 3 is 0.24 mm.

[0045] In one embodiment, the body is provided with a cavity located inside and for gas circulation, and a through hole 4 provided on its outer peripheral surface, wherein the through hole 4 is connected to the cavity. Figures 1 to 16 shown.

[0046] Preferably, the cavity is arranged inside the body and extends from the proximal end to the distal end. The cavity can be a cylinder, a cuboid or other geometric shapes, etc. Its specific shape can be set as needed and is not specifically limited here.

[0047] More preferably, the through hole 4 is provided on the outer peripheral surface of the body and passes through the inner and outer surfaces of the body to achieve communication between the cavity inside the body and the space outside the body, thereby facilitating the input of gas into the cavity.

[0048] More preferably, one through hole 4 can be provided, or multiple through holes can be provided, so as to meet the ventilation demand as needed, which is not specifically limited here.

[0049] Furthermore, preferably, the through hole 4 may be circular, or may be square, rectangular, or other geometric shapes, etc., which are not specifically limited here.

[0050] Further preferably, the through hole 4 can be arranged at the proximal end of the body, or at the distal end of the body, or at the central area of ​​the body, without specific limitation here. In this embodiment, the through hole 4 is arranged in the central area of ​​the body.

[0051] Furthermore, the total area of ​​the plurality of through holes 4 is greater than 40 square millimeters, preferably greater than 57 square millimeters, thereby ensuring normal inhalation of the patient, reducing lung pressure, and being beneficial for use by patients with weak lungs.

[0052] It should be noted that: in this embodiment, the total area of ​​the multiple through holes 4 is 60 square millimeters, which significantly increases the air intake area and greatly reduces the patient's inhalation pressure.

[0053] In one embodiment, the valve 3 faces the through hole 4 to close the through hole 4 during exhalation and deforms in a direction away from the through hole 4 during inhalation to allow external gas to enter the cavity through the through hole 4. Figure 12 shown.

[0054] Preferably, the valve 3 is located in the cavity of the main body and opposite the through hole 4, that is, the projection of the valve 3 toward the through hole 4 can cover the through hole 4, so that the valve 3 can abut against the inner surface of the main body and cover all the through holes 4 during exhalation to seal the through hole 4 and prevent the gas in the cavity from being discharged through the through hole 4.

[0055] More preferably, when the patient bites the proximal end of the body and exhales, gas enters the cavity, causing the air pressure in the cavity to increase, thereby causing the valve 3 to tightly abut against the inner wall of the body and block the through hole 4, preventing the gas in the cavity from being discharged through the through hole 4. The gas flows toward the distal end in the cavity and flows out from the opening at the distal end of the body, thereby achieving the purpose of patient exhalation training.

[0056] More preferably, when the patient inhales, the gas in the cavity enters the patient's mouth through the opening at the proximal end of the main body. At this time, the air pressure in the cavity decreases. Since the distal end of the main body is a one-way valve, the external gas cannot enter the cavity through the opening at the distal end of the main body. Therefore, part of the valve 3 bends and deforms in the direction away from the through hole 4. At this time, the valve 3 no longer blocks the through hole 4, thereby opening the through hole 4, and then the external gas enters the cavity through the through hole 4, meeting the patient's inhalation training needs.

[0057] In one embodiment, the body includes an articulator 1 located at the proximal end and a respirator 2 located at the distal end, wherein the articulator 1 includes a first portion 11 located at the distal end thereof, and the respirator 2 includes a second portion 21 located at the proximal end thereof, wherein the first portion 11 is connected to the second portion 21. Figures 1 to 4 shown.

[0058] Preferably, the articulator 1 and the respirator 2 are separately provided so as to meet different needs. The articulator 1 is used for the patient to occlude in order to achieve breathing training for the patient. The respirator 2 is a one-way valve, which only allows gas to flow from the proximal end to the distal end inside it, and does not allow gas to flow from the distal end to the proximal end, so as to meet the patient's exhalation needs.

[0059] More preferably, the first part 11 is arranged at the distal end of the articulator 1, and the axial length of the first part 11 can be set as needed and is not specifically limited here.

[0060] More preferably, the second portion 21 is provided at the proximal end of the respirator 2 , and the axial length of the second portion 21 can be set as required and is not specifically limited herein.

[0061] Furthermore, preferably, the first part 11 is connected to the second part 21 , and they can be connected by bonding, interference fit, hot melt connection, etc., which can be set as needed and is not specifically limited here.

[0062] Further preferably, an inner cavity 16 is provided inside the articulator 1, and an inner cavity is provided inside the respirator 2. The inner cavity 16 of the articulator 1 and the inner cavity of the respirator 2 constitute a cavity within the main body to enable gas to flow therein.

[0063] In one embodiment, the first portion 11 is received in the interior of the second portion 21 and is interference fit therewith.

[0064] Preferably, the first part 11 is accommodated inside the second part 21, thereby realizing the connection between the articulator 1 and the respirator 2, and the interiors of the two are connected to realize the communication of gas inside the two.

[0065] More preferably, the outer circumference of the first part 11 abuts against the inner circumference of the second part 21, and the outer diameter of the first part 11 is slightly larger than the inner diameter of the second part 21, so that the first part 11 and the second part 21 have an interference fit to enhance the stability and sealing of the connection between the two.

[0066] In one embodiment, the second portion 21 is received in the interior of the first portion 11 and has an interference fit therewith, such as Figures 1 to 4 shown.

[0067] Preferably, the second part 21 is accommodated inside the first part 11, thereby realizing the connection between the articulator 1 and the respirator 2, and the interiors of the two are connected, so as to realize the communication of gas inside the two.

[0068] More preferably, the outer circumference of the second part 21 abuts against the inner circumference of the first part 11, and the outer diameter of the second part 21 is slightly larger than the inner diameter of the first part 11, so that the first part 11 and the second part 21 have an interference fit to enhance the stability and sealing of the connection between the two.

[0069] More preferably, a protrusion 22 is provided on the outer surface of the second portion 21. The protrusion 22 may be in a block shape, a strip shape or other geometric shapes, etc. It may be provided as required and is not specifically limited here.

[0070] Preferably, one or more protrusions 22 may be provided. When multiple protrusions 22 are provided, they are arranged at intervals along the circumferential direction, and more preferably, they are arranged at equal intervals along the circumferential direction.

[0071] Further preferably, a connecting groove 14 is provided on the inner surface of the first part 11, and the shape of the connecting groove 14 is adapted to the shape of the protrusion 22, so that when the second part 21 is accommodated in the first part 11, the protrusion 22 is accommodated in the connecting groove 14 and interference fits therewith, thereby making the first part 11 and the second part 21 stably connected to prevent them from detaching.

[0072] Furthermore, the number of the connecting grooves 14 is the same as the number of the protrusions 22 and they are arranged in a one-to-one correspondence, so that each protrusion 22 is received in its corresponding connecting groove 14 to ensure the stability of the connection.

[0073] In one embodiment, the through hole 4 is provided on the articulator 1 and is located outside the first portion 11. Figures 5 to 12 shown.

[0074] Preferably, the through hole 4 is provided on the articulator 1 and is located in an area outside the first part 11. The through hole 4 passes through the inner and outer surfaces of the articulator 1, thereby connecting the inner and outer spaces of the articulator 1, so that the gas outside the articulator 1 can enter the interior of the articulator 1 through the through hole 4.

[0075] More preferably, when the through hole 4 is provided on the articulator 1 and is located in an area outside the first portion 11 , the valve 3 is fixed to the inner wall of the articulator 1 so as to block the through hole 4 .

[0076] It should be noted that it is the setting of the above structure that makes the structure simpler, and the second part 21 will not block the through hole 4 to prevent the through hole 4 from being blocked, so that the external gas can smoothly pass through the through hole 4 into the cavity inside the main body to meet the patient's inhalation needs.

[0077] In one embodiment, the through hole 4 is provided on the respirator 2 and is located outside the second portion 21 .

[0078] Preferably, the through hole 4 is provided on the respirator 2 and is located in an area outside the second portion 21. The through hole 4 passes through the inner and outer surfaces of the respirator 2, thereby connecting the inner and outer spaces of the respirator 2, so that the gas outside the respirator 2 can enter the interior of the respirator 2 through the through hole 4.

[0079] More preferably, when the through hole 4 is provided on the respirator 2 and is located in a region outside the second portion 21 , the valve 3 is fixed to the inner wall of the respirator 2 so as to block the through hole 4 .

[0080] It should be noted that it is the setting of the above structure that makes the structure simpler, and the first part 11 will not block the through hole 4 to prevent the through hole 4 from being blocked, so that the external gas can smoothly pass through the through hole 4 into the cavity inside the main body to meet the patient's inhalation needs.

[0081] In one embodiment, the body is further provided with a connecting portion 5 connected to the through hole 4, and the connecting portion 5 is a hole or a notch, wherein: the through hole 4 is provided on the first part 11 and the connecting portion 5 is provided on the second part 21; or, the through hole 4 is provided on the second part 21 and the connecting portion 5 is provided on the first part 11, as Figures 1 to 4 shown.

[0082] Preferably, the through hole 4 is connected to the connecting portion 5, so that the external gas enters the cavity inside the main body through the through hole 4 and the connecting portion 5, meeting the patient's inhalation needs.

[0083] More preferably, when the through hole 4 is provided on the first part 11, the connecting portion 5 is provided on the second part 21, so that when the first part 11 and the second part 21 are connected, the through hole 4 and the connecting portion 5 are stacked and connected in sequence, thereby allowing air to enter the interior of the body from the outside.

[0084] More preferably, when the through hole 4 is provided on the second part 21, the connecting portion 5 is provided on the first part 11, so that when the first part 11 is connected to the second part 21, the through hole 4 and the connecting portion 5 are stacked and connected in sequence, thereby allowing air to enter the interior of the body from the outside.

[0085] It should be noted that it is the arrangement of the through hole 4 and the connecting portion 5 that allows them to be arranged on the first part 11 and the second part 21 that are connected to each other, thereby shortening the length of the entire respiratory training device 100 and reducing its weight. As a result, when the patient wears the respiratory training device, excessive exertion of oral muscles causing local soreness or fatigue is reduced, and redness, swelling, ulcers and other problems caused by continuous pressure on the gums, tongue or buccal mucosa are reduced.

[0086] Further preferably, the connecting portion 5 may be a circular hole, a square hole or other geometric shapes, or a notch, etc. The user may set it according to needs, and no specific limitation is made here.

[0087] In one embodiment, the through hole 4 and the connecting portion 5 are coaxially arranged; and / or the distance h between the edge of the through hole 4 and the edge of the connecting portion 5 satisfies 0.1 mm ≤ h ≤ 5 m. Figure 2 and Figure 4 shown.

[0088] Preferably, the through hole 4 and the connecting portion 5 are coaxially arranged, that is, the central axes of the through hole 4 and the connecting portion 5 are collinear, so that the connecting portion 5 can fully cover the through hole 4, so that the air passing through the through hole 4 can quickly pass through the connecting portion 5 and flow into the cavity inside the main body, preventing the through hole 4 from being blocked.

[0089] More preferably, when the connecting portion 5 is projected onto the valve 3, the connecting portion 5 covers the entire valve 3, thereby preventing the connecting portion 5 from blocking the valve 3, ensuring that the valve 3 deforms smoothly during inhalation to allow external gas to enter the cavity inside the main body through the through hole 4.

[0090] More preferably, the through hole 4 and the connecting portion 5 are circular, and the radius of the connecting portion 5 is larger than the radius of the through hole 4, so that the connecting portion 5 can cover the entire through hole 4, ensuring that the air passing through the through hole 4 can pass through the connecting portion 5 smoothly and quickly.

[0091] Preferably, the distance h between the edge of the connecting portion 5 and the edge of the through hole 4 can be any value between 0.1 mm and 5 mm, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc. The specific value can be set as needed and is not specifically limited here.

[0092] It should be noted that: it is precisely the above-mentioned limitation on the range of the distance h between the edge of the through hole 4 and the edge of the connecting portion 5 that, when the through hole 4 is arranged on the first part 11 and the connecting portion 5 is arranged on the second part 21, the second part 21 plays a stable supporting role for the first part 11 and ensures that the gas quickly passes through the through hole 4 and the connecting portion 5; when the through hole 4 is arranged on the second part 21 and the connecting portion 5 is arranged on the first part 11, the first part 11 plays a stable supporting role for the second part 21 and ensures that the gas quickly passes through the through hole 4 and the connecting portion 5.

[0093] In one embodiment, there is one connecting portion 5 and multiple through holes 4. When the connecting portion 5 is projected onto the surface where the through holes 4 are located, the connecting portion 5 covers all the through holes 4. Figures 1 to 4 shown.

[0094] Preferably, there is one connecting portion 5 and multiple through holes 5, which can be two, three, four or more, etc. The user can set them according to needs, and no specific limitation is made here. Multiple through holes 5 can be arranged in a circle, or in a straight line, curve or other shapes, etc., and no specific limitation is made here.

[0095] More preferably, when the connecting portion 5 is projected onto the surface where the through holes 4 are located, the connecting portion 5 covers the through holes 4, so that all the through holes 4 are connected to the connecting portion 5, thereby improving the ability of air flow to pass through and reducing the patient's inhalation pressure.

[0096] In one embodiment, the communicating portion 5 and the through hole 4 are both provided in plurality, and the communicating portion 5 and the through hole 4 are the same in number and correspond one to one.

[0097] Preferably, the connecting portion 5 and the through hole 4 are both provided in plurality, for example, two, three, four or other numbers, etc. The user can set them as needed, and no specific limitation is made here.

[0098] More preferably, the number of the connecting portions 5 and the through holes 4 are the same and correspond one to one, so that each through hole 4 is connected to the corresponding connecting portion 5, so as to improve the ability of airflow to pass through, and the overall area of ​​the connecting portion 5 can be reduced, so as to improve the overall structural strength of the first part 11 and the second part 21.

[0099] More preferably, the area of ​​the through hole 4 is the same as the area of ​​the connecting portion 5 , thereby ensuring the efficiency of the airflow passing therethrough and maximizing the structural strength of the first portion 11 and the second portion 21 .

[0100] In one embodiment, the through holes 4 are provided in plurality and are sequentially spaced apart. Figures 1 to 7 、 Figure 10 and Figure 11 shown.

[0101] Preferably, a plurality of through holes 4 are provided, thereby significantly increasing the air intake volume and air intake efficiency, reducing the patient's inhalation pressure, and being more conducive to the effect of the patient's breathing training.

[0102] More preferably, the plurality of through holes 4 are arranged in sequence at intervals, so that the plurality of through holes 4 are concentrated in a required area to prevent dispersion from affecting the shielding and sealing effect of the valve 3 .

[0103] More preferably, multiple through holes 4 are arranged in sequence at equal intervals, which not only facilitates processing and manufacturing, but also ensures structural stability. At the same time, it ensures that the wind force applied to the valve 3 through the through holes 4 during inhalation is relatively uniform, so that the valve 3 can bend and deform smoothly.

[0104] Preferably, the multiple through holes 4 are arranged in a circular shape at intervals, or can be arranged in a square, elliptical shape, etc., which is not specifically limited here. In this embodiment, the multiple through holes 4 are arranged in a circular shape at intervals so that the wind force applied to the valve 3 through the through holes 4 is more uniform.

[0105] In one embodiment, the body is provided with a mounting hole 6, and the valve 3 is provided with a fixing member 33, and the fixing member 33 passes through the mounting hole 6 and is fixedly connected to the body. Figure 12 shown.

[0106] Preferably, the mounting hole 6 is provided on the body, and the mounting hole 6 passes through the inner and outer surfaces of the body and communicates with the inner cavity of the body. The mounting hole 6 can be circular, square or other geometric shapes, which is not specifically limited here.

[0107] It should be noted that when the through hole 4 is provided in the first portion 11, the mounting hole 6 is also provided on the first portion 11, thereby facilitating the fixing of the valve 3 to the inner wall of the first portion 11 and achieving the sealing and opening of the through hole 4. When the through hole 4 is provided in the second portion 21, the mounting hole 6 is also provided on the second portion 21, thereby facilitating the fixing of the valve 3 to the inner wall of the second portion 21 and achieving the sealing and opening of the through hole 4. By providing the through hole 4 and the mounting hole 6 on the same structural member, the fixing of the valve 3 and the sealing and opening of the through hole 4 by the valve 3 are facilitated.

[0108] More preferably, the mounting hole 6 is arranged near the through hole 4 so that the through hole 4 can be covered when the valve 3 is installed in the body. In this embodiment, multiple through holes 4 are arranged around the mounting hole 6, so that the valve 3 can be conveniently installed on the mounting hole 6 and the edge of the valve 3 can cover all the through holes 4, so that a uniform force is applied to the edge of the valve 3 through multiple through holes 4 arranged in sequence, thereby facilitating the opening of the edge of the valve 3.

[0109] Preferably, the fixing member 33 is fixedly connected to the valve 3, such as by bonding or hot-melt connection, or can be integrally formed, thereby improving the structural stability of the two. In this embodiment, the valve 3 and the fixing member 33 are integrally formed, which not only simplifies the process, but also has a simple structure and good stability.

[0110] Further preferably, the fixing member 33 is in the shape of an elongated strip, and the extension direction of the fixing member 33 intersects with the valve 3, so that the valve 3 can be fixed to the inner wall of the main body through the fixing member 33. In this embodiment, the extension direction of the fixing member 33 is perpendicular to the plane where the valve 3 is located, so that the valve 3 can be fully fitted to the inner wall of the main body when fixed to the inner wall of the main body, and the effect of blocking the through hole 4 is better.

[0111] Furthermore, the fixing member 33 is arranged opposite to the mounting hole 6, so that when the valve 3 is fixed on the inner wall of the body, the fixing member 33 passes through the mounting hole 6, so that the fixing member 33 is fixedly connected to the body, thereby facilitating the valve 3 to fit on the inner wall of the body.
