[0002] Breathing training is very important for children during their growth, especially when they suffer from respiratory diseases or undergo specific training (such as vocal music, sports, etc.). However, existing breathing training aids and methods are mainly designed for adults and have many problems in their application to children.

[0003] On the one hand, adult breathing training equipment has a complex structure and is difficult to operate, making it difficult for children to understand and use independently. It usually lacks interesting elements and cannot attract children to actively participate in training, resulting in poor training compliance. At the same time, the size and fit of the equipment are not suitable for children's facial features, which may cause discomfort when worn and even affect the training effect. On the other hand, existing training methods lack personalized design for children, and do not fully consider the differences in children's different growth stages and training needs, making it difficult to accurately adjust the training intensity and provide effective incentives.

[0004] To solve the above problems, the present invention provides a breathing training auxiliary device and training method specifically for children. By optimizing the structural design of the auxiliary device, such as adopting a breathing mask that conforms to the facial contour of children, connecting parts that are easy to adjust and fix, and an intelligent display screen with interesting and highly entertaining display, the comfort of children wearing the device and their enthusiasm for training are improved. At the same time, based on the children's respiratory function evaluation results, the breathing resistance is accurately set, and dynamically adjusted according to the children's performance and needs during the training process. Combined with staged training and effect evaluation feedback mechanism, personalized and scientific breathing training is achieved, which effectively improves children's respiratory function and promotes their healthy growth and training development. Summary of the invention

[0005] The purpose of the present invention is to provide a children's breathing training auxiliary device and training method, aiming to solve the problem that adult breathing training equipment in the prior art is not suitable for children, has a complex structure, is difficult to operate, is difficult for children to master, lacks fun, cannot attract children to actively train, and has low training compliance. In addition, the size and fit of the equipment do not meet the facial features of children, and are prone to cause discomfort and interfere with training when worn. At the same time, the existing training methods do not fully consider the differences in children's growth stages and training needs, and it is difficult to accurately control the training intensity and provide effective incentives, resulting in limited training effects. The present invention improves these problems to meet the special needs of children's breathing training.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A breathing training auxiliary device for children, comprising:

[0008] A training board, wherein the top of the training board is fixedly connected to a display bracket, the two ends of the training board are respectively fixedly connected to a second concave connecting plate, the front end of the display bracket is fixedly connected to a smart display screen, one side end is provided with a threaded hole, a screw is threadedly connected to the inner thread of the threaded hole, and one side end of the second concave connecting plate is fixedly connected to a spring piece;

[0009] A breathing resistance adjusting device, wherein the breathing resistance adjusting device is fixedly connected to the top of the training board;

[0010] A connecting tube, wherein the connecting tube is fixedly connected to a measuring port of the breathing resistance adjusting device;

[0011] A first concave connecting plate, wherein four first concave connecting plates are provided, and the four first concave connecting plates are all fixedly connected to the bottom end of the training board;

[0012] A breathing mask, wherein the breathing mask is fixedly connected to the circumferential surface of the breathing mask, and an air cushion is fixedly connected to one side end of the breathing mask;

[0013] A flexible band is fixedly connected to one side end of the breathing mask.

[0014] As a preferred solution of the present invention, S1, initial assessment step: a professional medical staff or trainer assesses the child's respiratory function, including vital capacity, respiratory rate, respiratory depth and other parameters, and according to the assessment results, sets a suitable initial respiratory resistance value by operating the respiratory resistance adjustment device;

[0015] S2. Training preparation steps: wear the breathing mask on the child's face through the flexible belt, adjust the position of the air cushion to make it fit the face comfortably and ensure good sealing, connect the connecting tube to the breathing resistance adjustment device to ensure there is no air leakage, start the training program through the smart display on the display bracket, and select the corresponding training mode according to the child's training purpose;

[0016] S3. Training process steps: During the training process, the child breathes through a breathing mask, and the breathing resistance adjustment device provides corresponding resistance for breathing according to the set mode. The smart display screen displays breathing-related data in real time, and displays interesting animations, patterns or gives virtual rewards according to the breathing parameters to encourage the child to continue training. The training is divided into multiple stages, each stage lasts for a specific duration, and a short rest time is set between stages. During the training stage, the breathing resistance can be gradually increased, decreased or kept constant according to the program to gradually improve the child's breathing ability;

[0017] S4. Effect evaluation and adjustment steps: After completing a training cycle, the child's respiratory function is evaluated again. According to the evaluation results, the connection tightness of the first concave connecting plate and the second concave connecting plate is adjusted by screwing, the overall stability or angle of the training plate is changed, and the parameters of the respiratory resistance adjustment device and the training mode are reset to optimize the subsequent training effect. If the child feels uncomfortable or has difficulty breathing during training, the connection between the second concave connecting plate and other components can be quickly released by the spring clip to stop training.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this solution, a breathing mask that conforms to the facial contour of children is used. Its shape and size fit the children's face. The air cushion design ensures both sealing and comfort, making children feel more comfortable and natural when wearing it, reducing the resistance caused by wearing discomfort. At the same time, the reasonable design of the toughness belt ensures that the mask is stably worn during training and will not easily loosen or fall off due to children's activities, further improving the convenience and stability of training, thereby improving children's acceptance and compliance with training;

[0020] The setting of the smart display screen adds rich fun elements to the training. It can display interesting animations and patterns in real time and give virtual rewards. For example, it can display cute cartoon image animations, give points or virtual props rewards according to whether the children's breathing parameters meet the standards. This instant visual and interactive feedback greatly attracts children's attention, transforming the originally monotonous breathing training into a fun and challenging game-like experience, stimulating children's inner motivation, and making them more willing to actively participate in the training and stick to it.

[0021] 2. In this program, professionals will conduct a comprehensive assessment of the child's respiratory function before training. Based on vital capacity, respiratory rate, respiratory depth and other parameters, combined with the child's age, physical condition and training purpose, the initial respiratory resistance value is tailored for each child. During the training process, the respiratory resistance can also be dynamically adjusted according to the child's performance and periodic assessment results to ensure that the training intensity always matches the child's actual ability, neither too easy to result in poor training results, nor too difficult to cause fear or frustration in the child, thereby achieving accurate and personalized training;

[0022] The training process is divided into multiple stages, each of which has a reasonable length and a short rest period. This arrangement is in line with the physical strength and attention characteristics of children, avoids excessive fatigue, and ensures the stability of the training effect. At the same time, the effect evaluation is carried out regularly, and the connection tightness of the training board, the parameters of the respiratory resistance adjustment device and the training mode are adjusted according to the evaluation results, forming a closed-loop feedback optimization system. By constantly adjusting and improving the training plan, the training can closely follow the development and changes of children's respiratory function, always maintain the most suitable state for individual children, realize scientific training management, effectively improve children's respiratory function, and promote their healthy growth and training development.

[0023] 3. In this solution, the possible discomfort of children is taken into consideration in the design of the training equipment, and safety emergency measures are set. For example, through the cooperation between the second concave connecting plate and the spring, when the child feels uncomfortable or has difficulty breathing, the connection can be quickly released, and the training can be stopped immediately. This design effectively avoids the risks that children may encounter during the training process, provides reliable protection for the safety of children, and makes parents and trainers feel more at ease, ensuring that the training process is carried out within a safe and controllable range.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1-Figure 2 , the present invention provides the following technical solutions:

[0031] A breathing training auxiliary device for children, comprising:

[0032] A training board 1, the top of the training board 1 is fixedly connected with a display bracket 4, the two ends of the training board 1 are respectively fixedly connected with 11 and a second concave connecting plate 3, the front end of the display bracket 4 is fixedly connected with a smart display screen 9, one side end of 11 is provided with a threaded hole, a screw is threadedly connected in the threaded hole, and one side end of the second concave connecting plate 3 is fixedly connected with a spring piece;

[0033] A breathing resistance adjusting device 10, the breathing resistance adjusting device 10 is fixedly connected to the top of the training board 1;

[0034] A connecting tube 5, the connecting tube 5 is fixedly connected to the measuring port of the breathing resistance adjusting device 10;

[0035] A first concave connecting plate 2, wherein four first concave connecting plates 2 are provided, and the four first concave connecting plates 2 are all fixedly connected to the bottom end of the training board 1;

[0036] A breathing mask 6, the breathing mask 6 is fixedly connected to the circumferential surface of the breathing mask 6, and an air cushion 8 is fixedly connected to one side end of the breathing mask 6;

[0037] The flexible band 7 is fixedly connected to one side end of the breathing mask 6 .

[0038] In the specific embodiment of the present invention, the training board 1 is the basic structural component of the entire auxiliary device, which plays the role of supporting and connecting other components, providing a stable installation platform for the display bracket 4, the breathing resistance adjustment device 10, the first concave connecting plate 2 and the second concave connecting plate 3, etc., ensuring the relative position stability between the various components, so that the entire device is not easy to shake or deform during use, thereby ensuring the normal progress of training.

[0039] The main function of the display bracket 4 is to provide a fixed support point for the smart display screen 9. By fixing the smart display screen 9 at a suitable position and angle, it is convenient for children to clearly see the screen display content during training, while ensuring the stability of the display screen during training, avoiding shaking and other factors that affect the display effect or distract the children's attention.

[0040] The intelligent display screen 9 is an important interface for interacting with children during training. It can display a variety of information, such as training guidance information, including breathing rhythm, depth requirements, etc., so that children can clearly understand the training goals. It can also provide real-time feedback of children's breathing data, such as numerical or graphical display of breathing frequency and depth, so that children and trainers can intuitively understand the training situation. In addition, by displaying interesting animations, game screens or reward information, the fun and motivation of training can be increased, and the enthusiasm and initiative of children to participate in training can be improved.

[0041] Four first concave connecting plates 2 are arranged at the bottom end of the training plate 1, and are used to connect or place the entire training device with an external support structure such as a tabletop, a training bed, etc. The concave design may facilitate cooperation with a specific support component, ensure the stability of the training device when in use, and prevent it from being displaced due to external forces such as the child's movements during the child's breathing training process;

[0042] The second concave connecting plate 3 is used in conjunction with the spring clip. The spring clip is used to provide a quick disassembly or emergency detachment function. At the end of the training, the connecting tube 5 can be placed in 3, and then the spring clip will clamp the connecting tube 5 to limit the position;

[0043] The breathing resistance adjustment device 10 can accurately adjust the resistance during breathing. The appropriate breathing resistance can be adjusted according to the child's age, training stage, physical condition such as disease type and severity, and training purpose such as rehabilitation training, training to improve respiratory function, etc. The appropriate resistance setting helps to enhance the child's respiratory muscle strength, improve respiratory function and breathing control ability;

[0044] The connecting tube 5 serves as a connecting passage between the breathing mask 6 and the breathing resistance adjusting device 10, and its function is to ensure that the breathing airflow can be smoothly transmitted between the two. It needs to have good sealing to prevent gas leakage, ensure that the resistance set by the breathing resistance adjusting device 10 can accurately act on the breathing process of the child, and also ensure the accuracy of the breathing data so that the smart display 9 can correctly feedback.

[0045] The breathing mask 6 is in direct contact with the child's face, is used to cover the child's mouth and nose, and guides the breathing airflow through the connecting tube 5 into the breathing resistance adjusting device 10. Its shape and size are designed according to the facial features of the child to ensure a good fit.

[0046] The air cushion 8 is located at one side of the breathing mask 6, and its function is to improve the sealing and comfort between the breathing mask 6 and the child's face. The air cushion 8 can be appropriately deformed according to the pressure on the child's face, filling the small gap between the mask and the face, which can prevent air leakage from affecting the training effect, and avoid discomfort or pressure on the child's face caused by the mask being too tight.

[0047] The flexible band 7 is fixed to one side end of the breathing mask 6 and is used to fix the breathing mask 6 on the child's head. The flexible band 7 needs to have appropriate elasticity and strength, which can ensure that the breathing mask 6 is stably worn on the child's face during training, will not loosen or fall off due to breathing movements or slight activities of the child, and will not cause excessive restraint or discomfort to the child's head.

[0048] For details, please refer to Figure 1-Figure 2S1. Initial assessment step: Professional medical staff or trainers assess the child's respiratory function, including vital capacity, respiratory rate, respiratory depth, etc. According to the assessment results, the respiratory resistance adjustment device 10 is operated to set a suitable initial respiratory resistance value.

[0049] S2, training preparation steps: wear the breathing mask 6 on the child's face through the flexible belt 7, adjust the position of the air cushion 8 to make it fit the face comfortably and ensure good sealing. Connect the connecting tube 5 to the breathing resistance adjustment device 10 to ensure that there is no air leakage. Start the training program through the smart display screen 9 on the display bracket 4, and select the corresponding training mode according to the child's training purpose, such as disease rehabilitation, vocal training, sports training, etc.

[0050] S3, training process steps: During the training process, the child breathes through the breathing mask 6, and the breathing resistance adjustment device 10 provides corresponding resistance for breathing according to the set mode. The intelligent display screen 9 displays breathing-related data in real time, and displays interesting animations, patterns or gives virtual rewards according to the breathing parameters such as frequency and depth that meet the set goals, to encourage children to continue training. The training is divided into multiple stages, each stage lasts for a specific duration such as 5-10 minutes, and a short rest time such as 1-2 minutes is set between stages. During the training stage, the breathing resistance can be gradually increased, decreased or kept constant according to the program to gradually improve the child's breathing ability.

[0051] S4, effect evaluation and adjustment step: After completing a training cycle, such as one week, the child's respiratory function is evaluated again. According to the evaluation results, the connection tightness of the first concave connecting plate 2 and the second concave connecting plate 3 is adjusted by screwing, the overall stability or angle of the training plate 1 is changed, and the parameters and training mode of the breathing resistance adjustment device 10 are reset to optimize the subsequent training effect. If the child feels uncomfortable or has difficulty breathing during training, the connection between the second concave connecting plate 3 and other components can be quickly released by the spring clip to stop training.

[0052] In this embodiment: S1: Initial assessment step: The importance of professional assessment: Assessment by professional medical staff or trainers is the basis for ensuring the scientificity and safety of training. They have professional knowledge and experience and can accurately measure the key parameters of children's respiratory function, such as vital capacity, which reflects the maximum ventilation capacity of the lungs, respiratory rate, which reflects the fast and slow rhythm of breathing, and breathing depth, which is related to the amount of gas exchange per breath. These parameters provide a basis for subsequent personalized training.

[0053] Initial setting of breathing resistance: According to the parameters obtained by evaluation, the breathing resistance adjustment device 10 is operated to set the initial value. Appropriate initial breathing resistance is one of the key factors for successful training. If the resistance is too large, it may cause the child to be unable to breathe normally or to have fear. If the resistance is too small, the training effect cannot be achieved.

[0054] S2: Training preparation steps: Wearing and adjusting the breathing mask 6: Wear the breathing mask 6 on the child's face through the flexible belt 7. During this process, you need to pay attention to adjusting the air cushion 8. The air cushion 8 must not only ensure that the mask fits comfortably with the face and avoids causing pressure or discomfort to the child's skin, but more importantly, it must ensure sealing. Good sealing is the prerequisite for accurately applying breathing resistance and obtaining accurate breathing data, and prevents air from leaking from the edge of the mask and affecting the training effect.

[0055] Connect the connecting tube to the system: Properly connect the connecting tube 5 to the breathing resistance adjustment device 10 and check for leaks. This step is crucial to maintaining the integrity of the training system, as any tiny leak may interfere with the accuracy of the breathing resistance, and thus affect the entire training process and data feedback.

[0056] Training program start and mode selection: Start the training program with the help of the smart display screen 9 on the display bracket 4. Select the appropriate training mode according to the specific purpose of the child's training. Different training purposes such as disease rehabilitation, vocal training, and sports training have different requirements for respiratory function. The corresponding training modes will be different in the law of respiratory resistance change, motivational content, etc., to better meet the training needs.

[0057] S3: Training process steps: Breathing and resistance coordination: During the training process, the child breathes through the breathing mask 6, and the breathing resistance adjustment device 10 provides accurate resistance for breathing according to the set mode. This interaction between resistance and breathing is the core link of the training. By gradually adapting to and overcoming different levels of resistance, the child's respiratory muscles are trained and the respiratory function is gradually improved.

[0058] Incentive feedback from the smart display 9: The smart display 9 plays an important role in motivation. It displays breathing-related data in real time, so that both children and trainers can clearly understand the training situation. At the same time, interesting animations, patterns or virtual rewards are displayed according to whether the breathing parameters meet the set goals. This incentive mechanism greatly improves children's enthusiasm for participation, makes boring training more interesting, and makes children more willing to cooperate in completing the training.

[0059] Training phase division: The training is divided into multiple phases, each phase lasts for a specific duration of 5-10 minutes, and a short rest time of 1-2 minutes is set between the phases. This phased training arrangement takes into account the physical strength and attention characteristics of children, avoids excessive fatigue, ensures the training effect, and also helps children maintain a good training state. During the training phase, the breathing resistance can be gradually increased, decreased, or kept constant according to the program. This dynamically changing resistance setting can better adapt to the development process of children's breathing ability and gradually improve their breathing ability.

[0060] S4: Effect evaluation and adjustment steps:

[0061] Periodic evaluation and adjustment: After a training cycle, such as a week, re-evaluation is carried out. This is a process of continuously optimizing the training effect. By comparing the respiratory function parameters before and after, the effectiveness of the training can be intuitively understood. According to the new evaluation results, the connection tightness of the first concave connecting plate 2 and the second concave connecting plate 3 is adjusted by screwing. This adjustment may change the overall stability or angle of the training plate 1, thereby affecting the use state of the entire training device, which may be related to the child's training posture, breathing efficiency, etc. At the same time, the parameters and training mode of the respiratory resistance adjustment device 10 are reset to further optimize subsequent training.

[0062] Safety emergency mechanism: Considering the discomfort that children may experience during training, safety emergency measures are set. If a child feels uncomfortable or has difficulty breathing, the spring clip can quickly release the connection between the second concave connecting plate 3 and other components, so that the training stops immediately to ensure the safety and health of the child. This design reflects the high attention paid to children's safety and ensures that the training process is carried out within a controllable and safe range.

[0063] Working principle and use process of the present invention: Initial evaluation stage:

[0064] Professional medical staff or trainers conduct a comprehensive respiratory function assessment on children, including the measurement of key parameters such as vital capacity, respiratory rate, and respiratory depth. These parameters can accurately reflect the child's lung function and breathing habits.

[0065] According to the detailed data obtained from the evaluation, the professional operates the breathing resistance adjustment device 10 to set a breathing resistance value suitable for the child's initial training. The determination of this initial value needs to comprehensively consider factors such as the child's age, physical condition, and training purpose, to ensure that it is challenging enough to promote the training effect, but does not cause the child to be unable to breathe normally or cause psychological burden due to excessive resistance.

[0066] Training preparation phase:

[0067] The trainer helps the child to wear the breathing mask 6 on the face through the flexible belt 7. In this process, the position of the air cushion 8 is carefully adjusted to ensure that it fits tightly against the child's face, which can ensure good sealing and prevent air leakage from affecting the application of breathing resistance and data collection accuracy, and also prevent the mask from being too tight to cause pressure or discomfort on the child's face, affecting the training experience.

[0068] Firmly connect the connecting tube 5 to the measuring port of the respiratory resistance adjusting device 10, and fully check whether there is air leakage at the connecting part. Any slight air leakage may lead to inaccurate training data, affect the judgment of the child's breathing condition and the implementation effect of the training plan.

[0069] The training program is started through the smart display screen 9 on the display bracket 4. According to the specific purpose of the child's training, such as disease rehabilitation, vocal training or sports training, the most suitable one is selected from the preset multiple training modes. Different training modes differ in the law of breathing resistance change, the display of motivational content, etc., so as to meet different training needs in a targeted manner.

[0070] Training process stages:

[0071] The child starts breathing training by wearing the breathing mask 6. The breathing resistance adjustment device 10 provides a precisely set resistance for the child's breathing according to the selected training mode. During the child's breathing process, the intelligent display screen 9 collects and displays breathing-related data in real time, such as numerical values ​​or intuitive graphical displays of parameters such as breathing frequency and depth, so that the child and the trainer can clearly and instantly understand the progress of the training.

[0072] When the child's breathing parameters reach or meet the goals set in the training mode, the smart display screen 9 will immediately display interesting animations, beautiful patterns or give virtual rewards, such as increased points, virtual props, etc. This real-time incentive feedback mechanism greatly stimulates the enthusiasm and initiative of children to continue training, making the originally boring breathing training full of fun and challenges.

[0073] The entire training process is scientifically divided into multiple stages, each of which lasts a specific length of time, usually 5-10 minutes. A short rest period of 1-2 minutes is set between stages. This arrangement fully takes into account the characteristics of children's limited physical strength and attention span. It can not only effectively prevent children from being overly tired due to long-term continuous training, but also help them maintain a good state during the training process, thereby ensuring the stability and sustainability of the training effect. In each training stage, the breathing resistance can be gradually increased, decreased or kept constant according to the preset program to gradually improve the child's breathing ability and adapt to their evolving respiratory function level.

[0074] Effect evaluation and adjustment stage:

[0075] After completing a training cycle, such as one week, professional medical staff or trainers will conduct a comprehensive assessment of the child's respiratory function again, focusing on comparing the changes in various respiratory function parameters between the two assessments. Through detailed analysis of these data, we can intuitively and accurately understand the effectiveness of the training at this stage and judge whether the training methods and parameter settings are reasonable and effective.

[0076] According to the new evaluation results, the connection tightness between the first concave connecting plate 2 and the second concave connecting plate 3 at both ends of the training board 1 is finely adjusted by using the screws on the first concave connecting plate 2 and the second concave connecting plate 3. This adjustment may change the overall stability or angle of the training board 1, and thus affect the state of the entire training device during use, which may be closely related to factors such as the child's training posture and breathing efficiency, so as to further optimize the training conditions.

[0077] At the same time, the parameters of the breathing resistance adjustment device 10 are reset to select a resistance value and a change mode that are more suitable for the current needs of improving the child's breathing ability. In addition, the training mode can be adjusted according to the evaluation results, such as optimizing the display method of the incentive content, changing the rhythm of the breathing resistance change, etc., to further improve the training effect and make full preparations for the next stage of training.

[0078] During the training process, if the child feels unwell or has difficulty breathing, the spring sheet at one side of the second concave connecting plate 3 can be used to quickly release the connection with other components, so that the training stops immediately, ensuring the safety and health of the child. This safety emergency mechanism provides a reliable guarantee for children's training, reflects the high attention paid to children's safety, and ensures that the training process is always carried out within a controllable and safe range.

[0079] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
