Abstract
Description
Technical Field
[0001] This invention relates to the field of rehabilitation assistive equipment technology, specifically to an instrument for nasal breathing training and a sleep aid. Background Technology
[0002] With increasing attention paid to respiratory health and mindfulness training, various nasal breathing training methods, especially alternating nasal breathing, have become important ways to improve ventilation and mental and physical well-being. However, existing techniques for implementing these training methods generally have significant limitations. The most common method relies on the user manually pressing one or both nostrils (e.g., with fingers). This method not only requires the user to maintain continuous concentration, making it difficult to perform deeply in a relaxed or meditative state, but also the control of the pressure and duration depends entirely on subjective feeling, which is neither precise nor scientific.
[0003] In an attempt to free up users' hands, some simple nasal clamps have appeared on the market. However, these devices are often simple in structure, using rigid materials and springs to provide clamping force. The clamping force of this design is fixed and uncalibrated, making it unable to adapt to the differences in nose shape and individual sensitivity among users. As a result, the clamping force is often either too strong, causing significant pressure and prolonged discomfort to the user's nostrils, or too weak, failing to effectively block airflow and significantly reducing the training effect. More importantly, these simple mechanical clamps have very limited functions and cannot automatically execute complex commands for alternating opening and closing of the left and right nostrils. This severely limits the automation, scientific nature, and safety of nasal breathing training, impacting its comfort and effectiveness. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an instrument for nasal breathing training and a sleep aid, solving the problems of uncontrollable clamping force, poor comfort, and difficulty in achieving automation and complex alternating training modes in existing nasal breathing training tools (such as finger pressing or simple clamps).

[0006] Preferably, the mounting mechanism includes a square box, the outside of which is fixedly connected to the upper and lower sides of the inside of the fixed box. A telescopic spring is fixedly connected inside the square box. A rotating plate is rotatably connected inside the square box. A T-shaped slider is provided inside the rotating plate. A T-shaped groove is slidably connected inside the T-shaped slider. A sliding rod is rotatably connected to the side of the T-shaped groove away from the rotating plate. An installation plate is detachably connected inside the fixed box. The installation plate has internal cavities on both the upper and lower sides.
[0007] Preferably, the adjustment mechanism includes a square frame, the rear side of which is fixedly connected to the front right side of the fixing belt. A button is slidably connected inside the square frame, and a circular plate is fixedly connected to the rear side of the button. A rotating rod is fixedly connected inside the square frame, and rotating plates are rotatably connected to the upper and lower sides of the rotating rod. A square sliding plate is rotatably connected to the rear side of the two rotating plates. A return spring is fixedly connected to the rear side of each circular plate. A moving column is fixedly connected to the rear side of each square sliding plate. Multiple through holes are opened inside the left side of the fixing belt.
[0008] Preferably, the front side of the rotating plate is rotatably connected to the left and right sides of the rear part, and the outside of the through hole of the movable column is slidably connected to the inside of the square frame.
[0009] Preferably, the external sliding connection is inside the square frame, and the rear sides of the plurality of return springs are fixedly connected to the rear inner wall of the square frame.
[0010] Preferably, one side of each of the two telescopic springs is fixedly connected to the opposite side of the two rotating plates, and the other side of each telescopic spring is fixedly connected to the inside of the square box.
[0011] Preferably, the outer side of the sliding rod is slidably connected to the inside of the square box, and the outer side of the rotating plate is engaged with the inner wall of the inner cavity.
[0012] Preferably, the external part of the solenoid valve is fixedly connected to the inside of the fixing band, and the external part of the three-way connecting pipe is fixedly connected to the inside of the fixing band.
[0013] Preferably, the air pump is externally fixedly connected to the inside of the fixed box, and the outside of the movable column engages with the inside of the through hole.
[0014] A sleep aid device includes a monitoring module, the monitoring module being externally fixedly connected to the rear inner wall of a fixed box, a data processing module being fixedly connected to the bottom inner wall of the fixed box, and a power module being installed inside the fixed box.
[0015] This invention provides an instrument for nasal breathing training and a sleep aid device. It has the following beneficial effects: 1. This invention precisely integrates an inflatable airbag, a solenoid valve, an air pump, and a pressure sensor, all under the unified control of a control module. This achieves a highly controllable automated nasal breathing training program. Compared to traditional manual pressing or simple clamps, the inflatable airbag of this invention provides a gentler and more comfortable clamping experience. The independent control of the solenoid valve can accurately execute complex alternating breathing commands. The addition of the pressure sensor forms a closed-loop feedback system, ensuring that the clamping force is always maintained within a safe and effective threshold, avoiding discomfort caused by excessive pressure, and greatly improving the scientific nature and safety of the training.
[0016] 2. The adjustment mechanism of the present invention provides a fast and reliable tightness adjustment solution. By simply pressing a button, the moving column can be disengaged from the current through hole, thereby allowing the fixing strap to slide freely to find the most comfortable fit. After releasing the button, the elasticity of the reset spring will immediately lock the moving column into the new hole position. The whole process can be completed with one hand, ensuring that the instrument can be worn quickly, stably and comfortably in various usage scenarios.
[0017] 3. This invention solves the pain point of difficult maintenance of integrated electronic products. When core components such as internal air pumps and control modules need to be repaired or replaced, maintenance personnel only need to operate the external sliding rod to release the locking of the mounting plate through the linkage of the internal rotating plate and slider. This mounting plate, which carries the core components, can be completely removed, making the maintenance work intuitive and efficient, greatly extending the overall service life of the equipment and reducing maintenance costs.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see the appendix Figure 1 This invention provides an instrument for nasal breathing training and a sleep aid, including a fixing strap 1, a training mechanism 2 installed inside the fixing strap 1, a fixing box 3 installed on the front right side of the training mechanism 2, mounting mechanisms 4 on both the upper and lower sides inside the fixing box 3, and an adjustment mechanism 5 installed on the right side inside the fixing strap 1. Please see the appendix Figure 3 To be continued Figure 5The training mechanism 2 includes two inflatable airbags 21, which are externally and fixedly connected to the rear side of the fixing strap 1. The inflatable airbags 21 are the actuators that directly act on the nostrils, applying pressure to the nasal wings through inflation to achieve precise control of nostril opening and closing. A connecting pipe 22 is installed on the outside of each inflatable airbag 21. The connecting pipe 22 serves as the airflow channel between the air pump 25 and the inflatable airbags 21, ensuring efficient and accurate delivery of compressed air. A solenoid valve 23 is installed on the right side of the connecting pipe 22. The solenoid valve 23 acts as a precision switch for gas flow, independently controlling the inflation and deflation of the left and right inflatable airbags 21 to achieve various complex breathing modes. A three-way connecting pipe 24 is installed on the right side of the two solenoid valves 23. The three-way connecting pipe 24 optimizes the airflow layout, connecting the air pump 25 to the two independent solenoid valves. The airflow distribution and connection between 23, the other end of the three-way connecting pipe 24 is equipped with an air pump 25, the air pump 25 is the power source in the system, responsible for generating and providing stable compressed air to drive the inflation airbag 21 to work, the right side of the fixed box 3 is fixedly connected to the control module 26, the control module 26 is the intelligent core of the whole instrument, processes user commands, schedules the coordinated work of various components, and executes the preset training program, the right side of the fixed box 3 is fixedly connected to the pressure sensor 27, the pressure sensor 27 monitors the internal pressure of the inflation airbag 21 in real time, to ensure that the clamping force is both effective and safe, and to avoid excessive pressure causing discomfort, the external fixed connection of the solenoid valve 23 is fixedly connected to the inside of the fixed belt 1, the external fixed connection of the three-way connecting pipe 24 is fixedly connected to the inside of the fixed belt 1, and the external fixed connection of the air pump 25 is fixedly connected to the inside of the fixed box 3; Specifically, the control module 26 starts the air pump 25 to generate airflow according to the preset program. The airflow is distributed to two independent solenoid valves 23 through the three-way connecting pipe 24. The control module 26 independently controls whether the airflow enters the left and right inflatable airbags 21 through the connecting pipe 22 by sending precise commands to the solenoid valves 23. When the inflatable airbags 21 are inflated, they apply pressure to the nostrils to achieve clamping. During this process, the pressure sensor 27 monitors the pressure data in the inflatable airbags 21 in real time and feeds it back to the control module 26. The control module 26 adjusts the working state of the air pump 25 or the opening and closing of the solenoid valves 23 accordingly, realizing an automated training scheme for precise, safe, and programmable closed-loop control of the clamping state and clamping force of the left and right nostrils.
[0022] Please see the appendix Figure 5 To be continued Figure 7The mounting mechanism 4 includes a square box 41, which is externally fixedly connected to the upper and lower sides of the interior of the fixed box 3. A telescopic spring 42 is fixedly connected inside the square box 41, providing the necessary elastic force to ensure smooth movement and reset of the rotating plate 43 when the sliding rod 44 is operated, achieving engagement and release. The rotating plate 43 is rotatably connected inside the square box 41. The rotating plate 43, through its rotational movement, controls engagement or disengagement with the inner cavity 46 of the mounting plate 45, and is a key component for achieving installation locking. A T-shaped slider 47 is provided inside the rotating plate 43, acting as a transmission component to convert the linear motion of the sliding rod 44 into the rotational motion of the rotating plate 43, ensuring operational precision. A T-shaped groove 48 is slidably connected inside the T-shaped slider 47, providing precise trajectory guidance and preventing deviations during sliding. Or jamming, the side of the T-shaped slide 48 away from the rotating plate 43 is rotatably connected to the sliding rod 44. The sliding rod 44 is the direct interface for the user to operate the installation mechanism 4. The internal locking mechanism is controlled by pressing. The fixed box 3 is detachably connected to the mounting plate 45. The mounting plate 45 is used to support and fix the core electronic module or sensor. Its detachable design greatly facilitates the maintenance and replacement of the equipment. The mounting plate 45 has an inner cavity 46 on both the upper and lower sides. The inner cavity 46 is the locking interface on the mounting plate 45. It is precisely matched with the external structure of the rotating plate 43 to achieve a firm locking and fixing. One side of the two telescopic springs 42 is fixedly connected to the opposite side of the two rotating plates 43. The other side of the telescopic springs 42 is fixedly connected to the inside of the square box 41. The outside of the sliding rod 44 is slidably connected to the inside of the square box 41. The outside of the rotating plate 43 is locked with the inner wall of the inner cavity 46. Specifically, the user operates the sliding rod 44, which is transmitted to the T-shaped slider 47 via the T-shaped groove 48, driving the rotating plate 43 fixed inside the square box 41 to rotate. During the rotation, the telescopic spring 42 provides the necessary elastic force to enable the external structure of the rotating plate 43 to precisely engage or disengage with the inner cavity 46 on the mounting plate 45. This allows the mounting plate 45, which carries the internal core components, to be firmly fixed inside the fixed box 3. It also facilitates quick unlocking and disassembly by operating the sliding rod 44 again when maintenance is required.
[0023] Please see the appendix Figure 2 and attached Figure 8The adjustment mechanism 5 includes a square frame 51, the rear of which is fixedly connected to the front right side of the fixing belt 1. A button 52 is slidably connected inside the square frame 51. The button 52 is a manual trigger for the user to intuitively adjust the tightness of the fixing belt 1, which is convenient and quick to adjust. A circular plate 59 is fixedly connected to the rear of the button 52. The circular plate 59 serves as a force transmission medium, effectively and evenly transmitting the pressing force of the button 52 to the return spring 56 and the sliding assembly. A rotating rod 53 is fixedly connected inside the square frame 51. The rotating rod 53 provides a stable rotation axis for the rotating plate 54, ensuring its smooth rotation during the adjustment process. Rotating plates 54 are rotatably connected to the upper and lower sides of the rotating rod 53. By rotating, the rotating plates 54 assist the moving column 57 in accurately aligning with and inserting or disengaging from the through hole 58 on the fixing belt 1, thereby achieving fine adjustment. A square sliding plate 55 is rotatably connected to the rear of the two rotating plates 54. The square sliding plate 55 is used to support and guide the moving column 57. When the button 52 is pressed, it slides along a preset path to achieve length adjustment. The rear side of the circular plate 59 is fixedly connected with a return spring 56. After the button 52 is released, the return spring 56 pushes the button 52 and the moving column 57 back to the original position and provides locking force to prevent the fixing strap 1 from being accidentally loosened. The rear side of the square sliding plate 55 is fixedly connected with the moving column 57. The moving column 57 is the component that is actually inserted into the through hole of the fixing strap 1 to lock the tightness. Its engagement determines the effective length of the fixing strap 1. The left side of the fixing strap 1 is provided with multiple through holes 58. The through holes 58 are multiple preset position holes on the fixing strap 1 for the moving column 57 to be selectively inserted to adapt to different user head circumferences. Specifically, the user presses button 52 inside the square frame 51. Button 52 pushes the circular plate 59, which in turn compresses the return spring 56, causing the square sliding plate 55 to slide inside the square frame 51. This sliding action disengages the moving post 57 on the rear side of the square sliding plate 55 from the currently locked through hole 58 on the fixing strap 1. At this time, the user can freely pull the fixing strap 1 to adjust the length, with the rotating rod 53 and rotating plate 54 providing guidance during this process. When the desired position is reached, button 52 is released, the return spring 56 springs back, pushing the circular plate 59 and the square sliding plate 55 back to their original positions, causing the moving post 57 to forcefully engage in a new through hole 58.
[0024] Please see the appendix Figure 4The monitoring module 6 is externally fixed to the rear inner wall of the fixed box 3. The monitoring module 6 is responsible for collecting the user's physiological data in real time, such as respiratory rate, depth or sleep status, to provide raw information for data analysis. The data processing module 7 is fixedly connected to the bottom inner wall of the fixed box 3. The data processing module 7 is the intelligent analysis center of the instrument, which receives and processes all monitoring data, and then outputs control commands or feedback according to the algorithm. The power module 8 is installed inside the fixed box 3. The power module 8 provides a stable and reliable power supply for all electronic components of the instrument to ensure that the equipment operates normally for a long time. Specifically, the power module 8 provides stable and reliable power to the monitoring module 6 and the data processing module 7. The monitoring module 6 is responsible for collecting the user's physiological data in real time and transmitting this information to the data processing module 7. The data processing module 7 receives and analyzes the data from the monitoring module 6, intelligently determines the user's breathing or sleep state based on algorithms, and generates control commands accordingly. This enables the instrument to perform intelligent analysis based on the user's real-time physiological state and make corresponding control decisions, thereby achieving automated sleep aid or training functions.
[0025] Working principle: When the instrument is in use, the fixing strap 1 is worn on the user's head, so that the two inflatable airbags 21 in the internal training mechanism 2 are located in the nostril areas on the left and right sides of the user, respectively. When nasal breathing training is required, the control module 26 sends a command to the solenoid valve 23 according to the preset training mode (e.g., bilateral clamping, left single-sided clamping, right single-sided clamping, or alternating clamping). The air pump 25 delivers air to the corresponding solenoid valve 23 through the three-way connecting pipe 24. According to the command of the control module 26, the solenoid valve 23 selectively opens or closes, thereby controlling the gas to enter or exit one or both of the two inflatable airbags 21. When gas enters the inflatable airbag 21, the airbag expands, generating external pressure on the user's nostrils, thereby clamping the nostrils and restricting or preventing nasal breathing. The pressure sensor 27 monitors the pressure of the airbag in real time and feeds the data back to the control module 26 to ensure that the clamping force is within a safe and effective range. At the same time, the control module 26 can also adjust the working state of the air pump 25 or the solenoid valve 23 according to the pressure data.
[0026] When internal components need to be repaired, the sliding rod 44 is pressed first. Pressing the sliding rod 44 causes the rotating plate 43 to rotate. The rotation of the rotating plate 43 further drives the T-shaped slider 47 to slide inside the T-shaped groove 48. During this process, the telescopic spring 42 is compressed or extended. When the outside of the rotating plate 43 engages with the inner cavity 46 of the mounting plate 45, the internal components are firmly fixed inside the fixed box 3. When the internal components need to be disassembled, the sliding rod 44 is pressed again to release the rotating plate 43 from the inner cavity 46. The mounting plate 45 can then be removed from the fixed box 3, thereby realizing the disassembly of the internal components.
[0027] The adjustment mechanism 5 is mainly used to adjust the tightness of the fixing strap 1 to ensure that the training mechanism 2 comfortably and effectively acts on the user's nose. The user adjusts the tightness by operating the button 52 inside the square frame 51. When the button 52 is pressed, its circular plate 59 compresses the return spring 56. This simultaneously moves the moving post 57 on the square sliding plate 55. The moving post 57 disengages from the structure with multiple through holes 58 inside the left side of the fixing strap 1. By pressing and releasing the button 52 and cooperating with the rotating plate 54 on the rotating rod 53, the rotating plate 54 is rotatably connected to the through holes 58, i.e., the adjustment holes of the fixing strap 1. This allows the moving post 57 to enter or disengage from different through holes 58, thereby changing the effective length of the fixing strap 1 to adjust the wearing tightness. After adjustment, the spring force of the return spring 56 will reset the button 52 and lock the current tightness.
[0028] As a sleep aid device, the monitoring module 6 can monitor data such as the user's breathing status, body movement, or nasal ventilation during sleep. The data processing module 7 is responsible for receiving data from the monitoring module 6 and the pressure sensor 27 and analyzing and processing it. For example, the data processing module 7 can intelligently control the training mechanism 2 to perform specific nasal breathing training based on the user's breathing pattern and nasal resistance during sleep, so as to improve nasal ventilation during sleep or guide a deeper breathing pattern, thereby achieving a sleep aid effect.
