A dynamic sealed respiratory training mask

Abstract

The application provides a dynamic sealing breathing training mask, and belongs to the technical field of breathing training. The mask comprises a body, an outer shell fixedly connected to the outer wall of the body, an upper positioning frame fixedly connected to the inner wall of the top of the body, a lower positioning frame fixedly connected to the inner wall of the bottom of the body, a through hole for breathing training installed on the body, and wearing mechanisms fixedly connected to the two sides of the body. A dynamic sealing assembly is used for sealing between the body and the cheeks of a user when the user performs open mouth breathing and speaking, and is connected to the upper positioning frame and the lower positioning frame. The dynamic sealing assembly can ensure good sealing effect between the body and the face of the user during open mouth breathing or open mouth speaking, and can prevent a gap from being formed between the face and the mask during open mouth breathing, so that all the air inhaled into the body of the user can pass through the filtering mechanism, and the air is clean enough.

Description

Technical Field

[0001] This invention relates to the field of breathing training technology, and in particular to a dynamically sealed breathing training mask. Background Technology

[0002] Deep inhalation and breath-holding technique is a technique developed in recent years to control the impact of respiratory movements on the movement of the radiotherapy target area. In breast cancer radiotherapy, deep inhalation and breath-holding technique is mostly used for left breast cancer patients and right breast cancer patients who need internal mammary lymph node irradiation. By inhaling deeply and holding the breath, the lungs expand to increase the distance between the chest wall and the heart, so that the heart is away from the radiotherapy field. In this process, patients need to wear various breathing training and management devices to carry out standardized free breathing and breath-holding training.

[0003] With existing breathing training masks, when a user speaks or inhales through their mouth, the movement of the mandible causes the skin in the mouth area to move downwards, backwards, or to the sides, partially disengaging from the sealing unit and creating a gap. Although this gap can be eliminated when the mouth is closed, it creates a breathing risk. The gap formed during speaking or inhaling allows a large amount of air from the external environment, along with pathogenic particles, to be inhaled without filtration. This not only reduces the safety of the air inhaled into the user's body but also affects the airtightness of the breathing training mask, thus impacting the training effect on the user. Therefore, this invention provides a dynamically sealed breathing training mask to meet this need. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dynamically sealed breathing training mask. By setting a dynamic sealing component, the mask can maintain a good seal between the mask and the user's face even when the user is breathing or speaking through their mouth. This prevents gaps from forming between the face and the mask while the user is speaking, ensuring that all the air inhaled by the patient passes through the filtration mechanism and is clean enough. The above settings can solve the problem of low safety in traditional breathing training masks during use.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A dynamically sealed breathing training mask includes a main body, an outer shell fixedly connected to the outer wall of the main body, an upper positioning frame fixedly connected to the top inner wall of the main body, a lower positioning frame fixedly connected to the bottom inner wall of the main body, a through hole for breathing training installed on the main body, and wearing mechanisms fixedly connected to both sides of the main body; and a dynamic sealing assembly for sealing between the main body and the cheek when the user breathes and speaks with their mouth open, the dynamic sealing assembly being connected to the upper positioning frame and the lower positioning frame respectively.

[0006] Optionally, the dynamic sealing assembly includes an upper frame fixedly connected to both sides of the upper positioning frame, and a lower frame fixedly connected to both sides of the lower positioning frame, with an arc-shaped soft pad fixedly connected to both the upper frame and the lower frame.

[0007] Optionally, a nasal bone positioning part is installed at the middle position of the upper positioning frame, and the contour of the nasal bone positioning part is adapted to the contour of the human nasal bone.

[0008] Optionally, cheekbone positioning parts are symmetrically installed at both ends of the upper positioning frame, and the contour of the cheekbone positioning parts is adapted to the contour of the human cheekbone.

[0009] Optionally, a first spiral sealing gasket is fixedly connected to the top inner wall of the upper positioning frame, and a first fitting surface is installed at one end of the first spiral sealing gasket. The upper positioning frame, the nasal bone positioning part, and the cheekbone positioning part are integrally manufactured structures.

[0010] Optionally, a jaw positioning part is installed at the middle position of the lower positioning frame, and the outline of the jaw positioning plate is adapted to the outline of the human jaw.

[0011] Optionally, mandibular positioning parts are symmetrically installed at both ends of the lower positioning frame, and the contour of the mandibular positioning parts is adapted to the contour of the human mandible.

[0012] Optionally, a second spiral sealing gasket is fixedly connected to the bottom inner wall of the lower positioning frame, and a second contact surface is installed at one end of the second spiral sealing gasket. The lower positioning frame, the mandibular positioning part, and the mandibular positioning part are integrally manufactured structures.

[0013] Optionally, a first plug is fixedly connected to one end of the upper frame, and a second plug is fixedly connected to one end of the lower frame. The first plug has a recessed portion, and the second plug has a protruding portion. The contours of the protruding portion and the recessed portion match, and the size of the first plug is larger than the size of the second plug.

[0014] Optionally, the arc-shaped cushion has a curved arc structure, and multiple arc-shaped cushions are evenly distributed on the inner walls of the upper frame and the lower frame, with the size and thickness of the arc-shaped cushions decreasing step by step.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a dynamic sealing component, the device and the user's face can still maintain a good seal when the user breathes or speaks through their mouth. No gaps will be formed between the face and the mask when the user speaks, ensuring that all the air inhaled into the patient's body can pass through the filtration mechanism and that the air is clean enough.

[0016] By incorporating an upper positioning frame within the dynamic sealing assembly, the upper positioning frame is positioned at the user's nasal bone location after the mask is worn. A nasal bone positioning part, conforming to the contour of the human nasal bone, is located in the middle of the upper positioning frame. This design aims to improve the fit during wear, enhancing both the fit between the upper positioning frame and the user's facial contours and the overall comfort. Cheek bone positioning parts, conforming to the contours of the human cheekbones, are also located on both sides of the upper positioning frame. This design further improves the fit between the sides of the upper positioning frame and the user's facial contours, thus ensuring stability during wear.

[0017] By setting a first and a second snail-shaped sealing gasket within the dynamic sealing assembly, both gaskets have a snail-shaped profile structure in the middle, and their functions are the same. Here, we take the first snail-shaped sealing gasket as an example to analyze its function and effect. One end of the first snail-shaped sealing gasket is fixed to the inner wall of the upper positioning frame, and the other end is fitted with a first contact surface. The first contact surface has an arc-shaped curved surface structure. When the user wears the mask, the first contact surface touches the user's face. When the user breathes or speaks, under the mutual pulling action of the upper and lower positioning frames, the first contact surface will pull the snail structure in the middle of the first snail-shaped sealing gasket under the action of friction, causing it to deform. During the deformation of the first snail-shaped sealing gasket, the pulling force is buffered, thus making it less likely for the upper and lower positioning frames to misalign or slide. This ensures the stability of the structure between the upper and lower positioning frames when the user opens their mouth, thereby ensuring the sealing effect of the top and bottom of the mask.

[0018] By setting an upper and lower skeleton within the dynamic sealing assembly, the upper and lower positioning frames of the breathing training mask provided in this application are not hollow structures. They are connected together by the upper and lower fixed fits. This arrangement makes the upper and lower positioning frames not separate independent structures. Under the connection of the upper and lower skeletons, the upper and lower positioning frames form a complete support system. This support system can provide all-round support and limit the body of the mask.

[0019] By incorporating an arc-shaped pad within the dynamic sealing assembly, the end of the arc-shaped pad furthest from the upper frame has an inwardly folded circular outline. This outline is designed to make the end structure of the arc-shaped pad more rounded, thus making it more comfortable when it touches the user's face. When the user opens their mouth, the arc-shaped pad increases the pressure on the user's face, and its rounded outline at the end still ensures the user's facial comfort. The arc-shaped pad is distributed in a gradually changing outline on the upper and lower frames. This arrangement is designed to adapt to the arc-shaped structure of the upper and lower frames, so that even when the user is not speaking, the arc-shaped pad can still fit tightly against the user's face, thus giving the mask excellent stability whether the user is opening or closing their mouth.

[0029] like Figures 1 to 16As shown, an embodiment of the present invention provides a dynamically sealed breathing training mask, including a body 1, a shell 101 fixedly connected to the outer wall of the body 1, an upper positioning frame 2 fixedly connected to the top inner wall of the body 1, a lower positioning frame 3 fixedly connected to the bottom inner wall of the body 1, a through hole for breathing training installed on the body 1, and wearing mechanisms fixedly connected to both sides of the body 1; a dynamic sealing assembly, which is used to seal between the body 1 and the cheek when the user breathes through their mouth and speaks, and is connected to the upper positioning frame 2 and the lower positioning frame 3 respectively. The breathing training mask provided in this application is mainly applicable to deep inhalation and breath-holding techniques. Breathing training masks have already appeared in this technical field. Therefore, the main body 1 proposed in this application is the main body of the breathing mask. The outer shell 101 of the main body 1 is mainly used to protect the main body 1. The through holes opened on the main body 1 are used for users to perform breathing training. The wearing mechanism installed on both sides of the main body 1 is mainly used to wear the main body 1 on the user's face. Here, the wearing mechanism adopts an elastic band structure. In the above structure, the working principle of the main body 1, the outer shell 101 and the wearing mechanism are all disclosed as prior art in this application, so they will not be described in detail. Optionally, a filter mechanism is set in the main body 1. The filter mechanism is used to filter the air inhaled into the main body 1, reduce the content of pollutant particles in the inhaled air, and reduce the damage to the user's respiratory tract during breathing training.

[0030] This application, by setting a dynamic sealing component, ensures that the main body 1 and the user's face maintain a good seal even when the user is breathing or speaking through their mouth. This prevents gaps from forming between the face and the mask while the user is speaking, ensuring that all air inhaled into the patient's body passes through the filtration mechanism and is sufficiently clean.

[0031] As one implementation method in this embodiment, such as Figures 4 to 16As shown, the dynamic sealing assembly includes an upper frame 4 fixedly connected to both sides of the upper positioning frame 2, and a lower frame 5 fixedly connected to both sides of the lower positioning frame 3. Arc-shaped soft pads 6 are fixedly connected to both the upper frame 4 and the lower frame 5. A nasal bone positioning part 201 is installed at the middle position of the upper positioning frame 2, the contour of which matches the contour of the human nasal bone. Cheekbone positioning parts 202 are symmetrically installed at both ends of the upper positioning frame 2, the contours of which match the contours of the human cheekbone. A first spiral-shaped sealing gasket 203 is fixedly connected to the inner top wall of the upper positioning frame 2. One end of the 3 is equipped with a first contact surface 204. The upper positioning frame 2, the nasal bone positioning part 201, and the cheekbone positioning part 202 are integrally manufactured structures. In the dynamic sealing assembly, the upper frame 4 and the lower frame 5, as well as the arc-shaped soft pad 6 on their inner walls, mainly play a sealing role. The upper frame 4 and the lower frame 5 can deform accordingly during the user's opening process, and the arc-shaped soft pad 6 helps to achieve a sealing effect during the deformation process. In the above operation, the upper positioning frame 2 and the lower positioning frame 3 drive the deformation of the upper frame 4 and the lower frame 5. The upper positioning frame 2 and the lower positioning frame 3 are both installed in this assembly. Inside the body 1, during actual wear, the upper positioning frame 2, lower positioning frame 3, upper skeleton 4, and lower skeleton 5 are all fitted with soft rubber pads. These structures support and shape the pads. The upper positioning frame 2 is installed on top of the body 1. When the mask is worn, the upper positioning frame 2 is positioned at the user's nasal bone. A nasal bone positioning part 201, conforming to the contour of the human nasal bone, is located in the middle of the upper positioning frame 2. This design aims to improve the fit during wear, enhancing the conformity between the upper positioning frame 2 and the user's facial contours. Furthermore, it can improve the user's comfort during wear, preventing discomfort caused by structural mismatch. The upper positioning frame 2 is also equipped with cheekbone positioning parts 202 on both sides that are adapted to the contour of the human cheekbone. This structure improves the fit between the upper positioning frame 2 and the user's facial contour to a certain extent, thereby ensuring the stability of the user during wear. The above structure makes the upper positioning frame 2 fit the contour of the human nose bone and cheekbone, thereby improving the comfort and stability during wear, and making the user's breathing training more effective.

[0032] Furthermore, the upper positioning frame 2, the nasal bone positioning part 201, and the cheekbone positioning part 202 are all integrally manufactured structures, and all are made of plastic. This design makes the upper positioning frame 2 easier to manufacture and process. Moreover, the plastic upper positioning frame 2 is inexpensive and lightweight, making it more suitable for use in breathing training masks. It can effectively reduce the weight and pressure on the user when wearing the mask, thereby improving wearing comfort. On the other hand, the plastic structure can deform under external force. This design makes it easier for the positioning frame 2, the nasal bone positioning part 201, and the cheekbone positioning part 202 to fit the contours of the human face, thereby improving sealing and comfort.

[0033] Furthermore, a first spiral-shaped sealing gasket 203 is installed on the top inner wall of the upper positioning frame 2. The first spiral-shaped sealing gasket 203 has a spiral-shaped outline structure in the middle. One end of the first spiral-shaped sealing gasket 203 is fixed to the inner wall of the upper positioning frame 2, and the other end is equipped with a first contact surface 204. The first contact surface 204 has an arc-shaped curved surface structure. When the user wears the mask, the first contact surface 204 abuts against the user's face. When the user breathes or speaks, under the mutual pulling action of the upper positioning frame 2 and the lower positioning frame 3, the first contact surface 204 will deform the spiral structure in the middle of the first spiral-shaped sealing gasket 203 under the action of friction. During the deformation of the spiral sealing gasket 203, the tensile force is buffered, which makes it less likely for misalignment and slippage to occur between the upper positioning frame 2 and the lower positioning frame 3. This ensures the structural stability of the upper positioning frame 2 and the lower positioning frame 3 during the user's opening process, thereby ensuring the sealing effect of the top and bottom of the mask. It is worth mentioning that the reason why the first spiral sealing gasket 203 is installed on the top of the upper positioning frame 2 is that when the user opens their mouth, the top of the upper positioning frame 2 will be subjected to tensile force first. Installing the first spiral sealing gasket 203 on the top of the upper positioning frame 2 can buffer the tensile force at the first time, thereby ensuring the stability of the upper positioning frame 2.

[0034] In this embodiment, as Figure 4 and Figures 9 to 13As shown, a mandibular positioning part 301 is installed at the middle position of the lower positioning frame 3. The outline of the mandibular positioning plate is adapted to the outline of the human mandible. Mandibular positioning parts 302 are symmetrically installed at both ends of the lower positioning frame 3. The outline of the mandibular positioning part 302 is adapted to the outline of the human mandible. A second spiral sealing gasket 303 is fixedly connected to the bottom inner wall of the lower positioning frame 3. A second fitting surface 304 is installed at one end of the second spiral sealing gasket 303. The lower positioning frame 3, the mandibular positioning part 301, and the mandibular positioning part 302 are integrally manufactured structures. Although the upper positioning frame 2 and the lower positioning frame are structurally different, their functions are the same. When the user wears the mask, the lower positioning frame 3 is positioned in the user's... The lower positioning frame 3 has a jaw positioning part 301 and a mandibular positioning part 302 at the lower jaw position. This is to improve the fit between the lower positioning frame 3 and the user's face, thereby improving the user's comfort and the stability of the lower positioning frame 3 during wear. The second snail-shaped sealing pad 303 at the bottom of the lower positioning frame 3 has the same function as the first snail-shaped sealing pad 203 on the upper positioning frame 2. Both are to absorb and buffer the pulling force during the user's opening process, thereby improving the stability of the upper positioning frame 2 and the lower positioning frame 3 during the user's opening process. This ensures that the top and bottom of the mask are well sealed when the user opens their mouth, improving the training effect and the safety of the user's inhaled air.

[0035] In this embodiment, as Figures 13 to 16 As shown, a first plug 401 is fixedly connected to one end of the upper frame 4, and a second plug 501 is fixedly connected to one end of the lower frame 5. A recess 402 is installed on the first plug 401, and a protrusion 502 is installed on the second plug 501. The contours of the protrusion 502 and the recess 402 match. The size of the first plug 401 is larger than that of the second plug 501. The arc-shaped soft pad 6 has a curved arc structure. Multiple arc-shaped soft pads 6 are evenly distributed on the inner walls of the upper frame 4 and the lower frame 5, and the size and thickness of the arc-shaped soft pads 6 decrease step by step. As mentioned above, the upper positioning frame 2, lower positioning frame 3, upper frame 4, and lower frame 5 are all wrapped externally during actual use. A rubber pad is provided. The above structure is designed to shape and support the pad, thereby improving the sealing effect of the pad on the user's face. Secondly, compared with traditional breathing training masks, the upper positioning frame 2 and the lower positioning frame 3 of the breathing training mask provided in this application are not hollow structures. They are connected together by the upper frame 4 and the lower fixed fit. This design makes the upper positioning frame 2 and the lower positioning frame 3 not separate independent structures. Under the connection of the upper frame 4 and the lower frame 5, the upper positioning frame 2 and the lower positioning frame 3 form a whole support system. This support system can provide all-round support and limit the body 1 of the mask.

[0036] Specifically, one end of the upper frame 4 is fixed to the upper positioning frame 2, and the other end is interlocked with the lower frame 5. One end of the lower frame 5 is fixed to the lower positioning frame 3, and the other end is interlocked with the upper frame 4. The surface of the first plug 401 has a slot to avoid the second plug 501, so that the second plug 501 can pass through the first plug 401. Since the contours of the protrusion 502 and the recess 402 match each other, they can interlock and limit each other. Therefore, when the second plug 501 passes through the first plug 401, the first plug 401 and the second plug 501 can be fixed together by the limiting effect of the protrusion 502 and the recess 402. The non-fixed connection between the upper frame 4 and the lower frame 5 makes the overall structure of the mask more flexible, which makes the mask more convenient and efficient in the later maintenance and disassembly process.

[0037] Furthermore, both the upper frame 4 and the lower frame 5 are arc-shaped structures. When they are interlocked, there will be a protruding contour at the connection point facing the user's face outwards. Arc-shaped soft pads 6 are provided on the inner walls of the upper frame 4 and the lower frame 5. The size and thickness of the arc-shaped soft pads 6 gradually decrease from the connection point of the upper frame 4 and the lower frame 5 towards both ends, reaching their maximum size and thickness at the connection point. When the user opens their mouth, their jaw opens, causing the lower positioning frame 3 to shift. At this time, the lower positioning frame 3 pulls on the lower frame 5, and the lower frame 5, under tension, pulls on the upper frame 4. The upper positioning frame 2 will also be pulled by the upper frame 4. When the upper frame 4 and the lower frame 5 are pulled, their arc-shaped structures will deform. During the deformation, the protruding contour at the connection between the upper frame 4 and the lower frame 5 will shrink towards the user's face. At the same time, the arc-shaped soft pad 6 located at this position will also move towards the user's face. During the movement of the arc-shaped soft pad 6, it will press against the user's face, and the squeezing force of the arc-shaped soft pad 6 will improve the seal between the mask and the user's face. This setting ensures the seal on both sides of the mask when the user speaks or breathes, thereby improving the safety and training effect of the entire training process.

[0038] Furthermore, the overall structure of the curved pad 6 is arc-shaped. The end of the curved pad 6 away from the upper frame 4 has an inwardly turned circular outline. This outline is designed to make the end structure of the curved pad 6 more rounded, thus making the curved pad 6 more comfortable when it touches the user's face. When the user opens their mouth, the curved pad 6 increases the pressure on the user's face. At this time, its rounded outline at the end can still ensure the user's face is comfortable. The curved pad 6 has a gradually changing outline distribution on the upper frame 4 and the lower frame 5. This arrangement is to adapt to the arc-shaped structure of the upper frame 4 and the lower frame 5, so that when the user is not speaking, the curved pad 6 can still fit tightly against the user's face, thus making the mask very stable whether the user is opening or closing their mouth.

[0039] In the above solution, the curved soft pad 6 and the upper frame 4 are manufactured as a single piece and are made of plastic. This design not only reduces manufacturing costs but also makes it lighter and more comfortable for users to wear the mask.

[0040] The working principle of the technical solution provided by this invention is as follows: In use, the user wears the main body 1 onto their face using the wearing mechanism. Because the main body 1 has openings, air enters the user's body through these openings when they breathe, thus achieving a breathing training effect. After the mask is worn, the upper positioning frame 2 is positioned at the user's nasal bone location. A nasal bone positioning part 201, conforming to the contour of the human nasal bone, is located in the middle of the upper positioning frame 2. This structure is designed to improve the fit during wear, enhancing both the fit between the upper positioning frame 2 and the user's facial contours and the user's comfort. Cheek bone positioning parts 202, conforming to the contour of the human cheekbones, are also located on both sides of the upper positioning frame 2. This structure further improves... The upper positioning frame 2 conforms well to the user's facial contours on both sides, ensuring stability during wear. Once the user has put on the mask, the lower positioning frame 3 is positioned at the user's jawline. The lower positioning frame 3's upper and lower jaw positioning parts 301 and mandibular positioning parts 302 are designed to improve the fit between the lower positioning frame 3 and the user's face, thereby enhancing user comfort and the stability of the lower positioning frame 3 structure during wear. The upper positioning frame 2 has a first snail-shaped sealing pad 203, and the lower positioning frame 3 has a second snail-shaped sealing pad 303. The first and second snail-shaped sealing pads 203 serve the same purpose. Here, we will use the first snail-shaped sealing pad 203 as an example to explain their working principle and function. The first spiral-shaped sealing gasket 203 has a spiral-shaped profile structure in the middle. One end of the first spiral-shaped sealing gasket 203 is fixed to the inner wall of the upper positioning frame 2, and the other end is equipped with a first contact surface 204. The first contact surface 204 has an arc-shaped curved surface structure. When the user wears the mask, the first contact surface 204 abuts against the user's face. When the user breathes or speaks, under the mutual pulling action of the upper positioning frame 2 and the lower positioning frame 3, the first contact surface 204 will pull the spiral structure in the middle of the first spiral-shaped sealing gasket 203 under the action of friction, causing deformation. During the deformation process, the first spiral-shaped sealing gasket 203 will buffer the pulling force, thereby making it less likely for the upper positioning frame 2 and the lower positioning frame 3 to misalign or slide, ensuring that the upper positioning frame 2 and the lower positioning frame 3 are secure when the user speaks. The stability of the structure between the upper positioning frame 2 and the lower positioning frame 3 ensures the sealing effect at the top and bottom of the mask. It is worth mentioning that the reason the first spiral sealing gasket 203 is installed on the top of the upper positioning frame 2 is that when the user opens their mouth, the top of the upper positioning frame 2 will be subjected to tensile force first. Installing the first spiral sealing gasket 203 on the top of the upper positioning frame 2 can buffer the tensile force immediately, thus ensuring the stability of the upper positioning frame 2. Compared with traditional breathing training masks, the breathing training mask provided in this application does not have a hollow structure between the upper positioning frame 2 and the lower positioning frame 3. The two are connected together by the upper frame 4 and the lower fixing mechanism. This design ensures that the upper positioning frame 2 and the lower positioning frame 3 are not separate independent structures.The connection between the upper frame 4 and the lower frame 5 creates a unified support system between the upper positioning frame 2 and the lower positioning frame 3. This system provides all-around support and limitation for the main body 1 of the mask. Both the upper frame 4 and the lower frame 5 are arc-shaped structures. When they are interlocked, a protruding contour facing the user's face is formed at the connection point. Arc-shaped soft pads 6 are installed on the inner walls of the upper frame 4 and the lower frame 5. The size and thickness of the arc-shaped soft pads 6 gradually decrease from the connection point of the upper frame 4 and the lower frame 5 towards both ends, reaching their maximum size and thickness at the connection point. When the user opens their mouth, their jaw opens, causing the lower positioning frame 3 to shift. The lower positioning frame 3 pulls on the lower frame 5, which in turn pulls on the upper frame 4. At the same time, the upper positioning frame 2 also receives tension from the upper frame 4. When tension arises between the upper frame 4 and the lower frame 5, their curved structures deform. During this deformation, the protruding contour at the connection point between the upper frame 4 and the lower frame 5 shrinks towards the user's face. Simultaneously, the curved soft pad 6 located at this position moves towards the user's face. As the curved soft pad 6 moves, it presses against the user's face, and the pressure from the curved soft pad 6 improves the seal between the mask and the user's face. This design ensures a tight seal on both sides of the mask when the user speaks or breathes, thereby improving safety and training effectiveness throughout the entire training process.
