Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically to an adjustable breathing exerciser for breathing training. Background Technology

[0002] A breathing exerciser is a device used to train and restore respiratory function. It typically consists of a mouthpiece, inspiratory volume body, indicator bulb, and inlet tube, among other components. Its main functions include strengthening respiratory muscles, increasing lung ventilation, improving respiratory rhythm, promoting sputum expectoration, and assisting in the recovery of respiratory function, as detailed below:

[0003] 1. Strengthen respiratory muscles: By setting different resistance levels for inhalation or exhalation training, respiratory muscle groups such as the diaphragm and intercostal muscles can be specifically exercised. Long-term use can improve muscle contraction ability and relieve respiratory weakness.

[0004] 2. Increase lung ventilation: During training, actively increase the depth of breathing to promote full expansion of the alveoli, increase the amount of air inhaled and exhaled with each breath, and gradually improve the effective ventilation efficiency of lung tissue.

[0005] 3. Improve breathing rhythm: Guided by components such as indicator balls, regular deep breathing is encouraged, helping to correct shallow, rapid, and irregular breathing habits, establish a stable and deep breathing pattern, and reduce breathing energy consumption.

[0006] 4. Promotes sputum expectoration: Deep breathing exercises can cause airway vibration and increase lung pressure, which helps to loosen sputum in the airway, making it easier to be expelled through coughing and reducing the risk of lung infection.

[0007] 5. Assisted respiratory function recovery: For patients who are recovering from surgery or lung disease, regular use of a respiratory trainer can gradually restore damaged respiratory function, shorten recovery time, and reduce respiratory-related complications.

[0008] In the field of existing respiratory training technology, traditional multi-sphere respiratory training devices typically employ a structure with three independent spheres and corresponding chambers. Airflow propels spheres of varying weights up and down within their respective chambers to provide three preset fixed resistance levels. While this structure can achieve basic respiratory muscle strength training, it suffers from significant structural defects and technical limitations in practical application. Because the resistance value relies entirely on the fixed weight of the spheres themselves, it only provides three preset resistance levels, making fine-tuning based on the patient's specific muscle strength level impossible. When a patient's muscle strength falls between two resistance levels, they often face the dilemma of "insufficient low resistance and inability to complete high resistance," resulting in a mismatch between training intensity and the patient's actual ability. Furthermore, they can only focus on one mode of breathing, either exhalation or inhalation, severely impacting the suitability and effectiveness of rehabilitation training. In addition, traditional multi-sphere structures typically lack digital data acquisition and feedback capabilities; medical staff can only make rough assessments by visually estimating the sphere height, making it difficult to obtain precise respiratory pressure values, which is detrimental to developing scientifically personalized rehabilitation plans. Summary of the Invention

[0009] The purpose of this invention is to provide an adjustable breathing exerciser for breathing training, in order to solve the problems of poor resistance adaptability, inconvenience in recording, and insufficient hygiene protection in the existing breathing apparatus, which makes it difficult to balance functionality, accuracy and safety of use.

[0010] To achieve the above objectives, the present invention provides the following technical solution: an adjustable breathing exerciser for breathing training, comprising a hollow base and a connecting air tube connected to the base via a pipe, wherein an assessment mechanism for real-time assessment of the patient's breathing status is installed on the upper side of the base via a connector.

[0011] The testing organizations include:

[0012] The transparent tube has visible scale lines on its sidewalls along the axial direction, and several vent holes are equidistantly opened on the upper circumference of the transparent tube.

[0013] Magnetic ring one is fixedly connected to the top of the transparent tube and is used to generate a controllable magnetic field when energized.

[0014] The second magnetic ring is made of lightweight plastic. A permanent magnet is fixedly attached to one side of the ring. It is slidably and coaxially installed inside the transparent tube. Several balls are equidistantly hinged to the side circumference of the second magnetic ring. The inside of the second magnetic ring is provided with a clamping member for restricting the rolling of the balls.

[0015] The base is also equipped with a control system for controlling the operation of the testing organization. The control system includes a mounting box fixedly installed on the base. The mounting box is equipped with a current adjustment module and a hovering control module. Both the magnetic ring two and the mounting box are equipped with a power supply module and a wireless transmission module. The current adjustment module is electrically connected to the magnetic ring one and is used to adjust the magnitude and direction of the current in the magnetic ring one.

[0016] When the magnetic ring 2 is subjected to the thrust or drag force of the airflow, it interacts with the magnetic field generated by the magnetic ring 1 and moves along the tube, and is suspended at the scale position where the magnetic force and the airflow force are balanced.

[0017] The training resistance can be adjusted by changing the magnetic strength of the magnetic ring by adjusting the current magnitude, and the magnetic direction of the magnetic ring can be changed by switching the current direction to switch between exhalation training mode and inhalation training mode.

[0018] Furthermore, the connector includes an integrally fixed interface fixedly connected to the base, the interface and the base are connected internally, and a rotating sleeve is threadedly connected to the interface through a threaded structure. The rotating sleeve is rotatably installed on the lower side of the transparent tube, and a sealing ring is filled between the bottom of the transparent tube and the bottom of the interface.

[0019] Furthermore, the clamping component includes a turntable rotatably installed inside the second magnetic ring. A rotating shaft is fixedly connected to the center of the turntable. The rotating shaft is driven by a driving component fixedly installed outside the second magnetic ring. The driving component is a micro motor. Several inclined slots are provided on the turntable. Sliding pins are movably embedded in the inclined slots. The sliding pins are fixedly installed on a movable rod. The movable rod slides through the side wall of the second magnetic ring. A friction block is fixedly connected to the end of the movable rod away from the turntable. A movable groove for sliding guidance of the friction block is provided on the side wall of the second magnetic ring.

[0020] Furthermore, the power supply module inside the mounting box is electrically connected to the current adjustment module and the wireless transmission module, the power supply module on the second magnetic ring is electrically connected to the drive component of the clamping part and the wireless transmission module thereon, the wireless transmission module on the second magnetic ring is wirelessly connected to the wireless transmission module inside the mounting box, and the hovering control module controls the operation of the drive component in the clamping part through the wireless transmission module.

[0021] Furthermore, when the current regulation module outputs a current in the first direction, a repulsive force is generated between magnetic ring one and magnetic ring two, and the direction of the repulsive force is the same as the direction of gravity.

[0022] The user blows air into the bottom of the transparent tube, generating an upward airflow. The magnetic ring II rises and suspends under the action of the airflow, overcoming repulsion and gravity, thus achieving the exhalation training mode.

[0023] Furthermore, when the current regulating module outputs a current in the second direction, an attractive force is generated between magnetic ring one and magnetic ring two, and the direction of the attractive force is opposite to the direction of gravity.

[0024] The user inhales from the top of the transparent tube, generating an upward airflow drag force. The magnetic ring II overcomes gravity and rises and suspends under the combined action of the airflow drag force and suction force, thus realizing the inhalation training mode.

[0025] Furthermore, the magnetic ring one includes:

[0026] Excitation coils are used to generate magnetomotive force;

[0027] A magnetic core, located inside the excitation coil, is used to enhance and guide the magnetic field;

[0028] The magnetically conductive outer shell covers the outside of the excitation coil and together with the magnetically conductive core, forms a closed magnetic circuit;

[0029] The end face of the magnetic core facing the second magnetic ring is conical or stepped, so that the electromagnetic force on the second magnetic ring is basically constant at different displacement positions.

[0030] Furthermore, the visual scale line includes scale group one and scale group two. Scale group one corresponds to the blowing pressure value in the exhalation training mode, and scale group two corresponds to the inhalation negative pressure value in the inhalation training mode.

[0031] Furthermore, the inner wall of the transparent tube and the surface of the second magnetic ring are coated with a hydrophobic and oleophobic coating. A ring-shaped filter membrane is attached and fixed to the inner wall of the transparent tube at the position corresponding to the air vent. Vertically distributed guide grooves are opened on the inner wall of the transparent tube at the positions corresponding to several ball bearings.

[0032] Compared with the prior art, the adjustable breathing exerciser for breathing training provided by the present invention has the following beneficial effects:

[0033] This invention, through multi-dimensional innovation in magnetic circuit structure, intelligent control, and hygiene protection, designs a comprehensive, precise, and highly hygienic intelligent breathing training device. Its significant beneficial effects are reflected in the following four aspects:

[0034] 1. In terms of training modes, through the electromagnetic coupling design of magnetic ring one and magnetic ring two, combined with the built-in power supply module and wireless transmission module, the electronic switching between exhalation and inhalation bidirectional training modes is realized. Users do not need to manually adjust, and the device can automatically match the resistance direction according to the breathing cycle, which greatly improves the continuity and convenience of training.

[0035] 2. Regarding resistance adjustment, the magnetic ring one adopts a unique closed magnetic circuit structure combined with conical magnetic poles to ensure that the magnetic ring two is subjected to uniform force at different suspension positions inside the transparent tube. This design enables the training resistance to be truly linearly adjustable, and medical staff can make fine settings according to the patient's muscle strength level, thereby developing a more scientific and personalized rehabilitation plan.

[0036] 3. Regarding data recording, the magnetic ring II is equipped with a micro-clamping mechanism. At the end of the training, a micro motor can be driven by a wireless command to press the friction block against the ball, precisely locking the magnetic ring II at the maximum displacement position of this training. This effectively avoids the reading deviation caused by the inertial swaying of the float in traditional equipment, greatly facilitating medical staff to accurately record training data and providing a reliable basis for rehabilitation assessment.

[0037] 4. In terms of hygiene protection, the inner wall of the transparent tube is coated with a hydrophobic and oleophobic coating to effectively prevent bacterial saliva droplets from adhering and remaining; a high-efficiency filter membrane is set at the vent to block external pollutants from entering. This dual hygiene protection design, combining internal and external protection, cuts off the chain of cross-infection transmission at the source and significantly improves the safety of medical devices in multi-patient shared scenarios.

[0047] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] As attached Figure 1 To be continued Figure 6 As shown:

[0049] Example 1:

[0050] The present invention provides an adjustable breathing exerciser for breathing training, including a hollow base 3 and a connecting trachea 2 connected to the base 3 through a pipe. The upper side of the base 3 is equipped with an assessment mechanism 1 for real-time assessment of the patient's breathing status via a connector 14.

[0051] Evaluation organization 1 includes:

[0052] The transparent tube 11 has visible scale lines on its sidewall along the axial direction, and several vent holes 111 are equidistantly opened on the upper circumference of the transparent tube 11.

[0053] Magnetic ring 5 is fixedly connected to the top of transparent tube 11 and is used to generate a controllable magnetic field when energized.

[0054] The second magnetic ring 6 is made of lightweight plastic. A permanent magnet is fixedly attached to one side of the ring. It is slidably and coaxially installed inside the transparent tube 11. Several balls 73 are equidistantly hinged to the side circumference of the second magnetic ring 6. A clamping member 7 is provided inside the second magnetic ring 6 to restrict the rolling of the balls 73.

[0055] The base 3 is also equipped with a control system 4 for controlling the operation of the testing mechanism 1. The control system 4 includes a mounting box 41 fixedly installed on the base 3. The mounting box 41 is equipped with a current adjustment module 42 and a hovering control module 44. The magnetic ring 6 and the mounting box 41 are also equipped with a power supply module 45 and a wireless transmission module 43. The current adjustment module 42 is electrically connected to the magnetic ring 5 and is used to adjust the current magnitude and current direction of the magnetic ring 5.

[0056] When the magnetic ring 6 is subjected to the thrust or drag force of the airflow, it interacts with the magnetic field generated by the magnetic ring 5 and moves along the tube, and is suspended at the scale position where the magnetic force and the airflow force are balanced.

[0057] The training resistance can be adjusted by changing the magnetic strength of the magnetic ring 5 by adjusting the current magnitude, and the magnetic direction of the magnetic ring 5 can be changed by switching the current direction to switch between exhalation training mode and inhalation training mode.

[0058] Working principle: The base 3 serves as the air distribution center, stably delivering the airflow generated by the user's breathing to the testing unit 1. The control system 4 centrally manages the power supply, communication, and current regulation to achieve intelligent control. The testing unit 1 can be detached and installed via the connector 14, facilitating cleaning and maintenance.

[0059] The connector 14 includes an interface 142 integrally fixedly connected to the base 3. The interface 142 is internally connected to the base 3. A rotating sleeve 141 is threadedly connected to the interface 142 via a threaded structure. The rotating sleeve 141 is rotatably installed on the lower side of the transparent tube 11. A sealing ring 143 is filled between the bottom of the transparent tube 11 and the bottom of the interface 142.

[0060] Working principle: When installing the transparent tube 11: Align the rotating sleeve 141 on the lower side of the transparent tube 11 with the interface 142, rotate the rotating sleeve 141, the rotating sleeve 141 moves downward along the thread, the transparent tube 11 is gradually pressed, the sealing ring 143 is compressed, and an airtight connection is formed. When disassembling the transparent tube 11: Rotate the rotating sleeve 141 in the opposite direction, the rotating sleeve 141 moves upward, the transparent tube 11 is loosened, and it can be removed for cleaning.

[0061] The threaded connection design allows for tool-free assembly and disassembly, facilitating cleaning and disinfection. The 143 sealing ring ensures an airtight seal under compression, preventing air leakage from affecting training accuracy.

[0062] The clamping member 7 includes a turntable 77 rotatably installed inside the magnetic ring 6. A rotating shaft 74 is fixedly connected to the center of the turntable 77. The rotating shaft 74 is driven by a driving component fixedly installed outside the magnetic ring 6. The driving component is a micro motor. Several inclined slots 75 are provided on the turntable 77. Sliding pins 76 are movably embedded in the inclined slots 75. The sliding pins 76 are fixedly installed on the movable rod 71. The movable rod 71 slides through the side wall of the magnetic ring 6. A friction block 72 is fixedly connected to the end of the movable rod 71 away from the turntable 77. An active groove 61 is provided on the side wall of the magnetic ring 6 for sliding guidance of the friction block 72.

[0063] The power supply module 45 inside the mounting box 41 is electrically connected to the current adjustment module 42 and the wireless transmission module 43. The power supply module 45 on the magnetic ring 6 is electrically connected to the drive component of the clamping member 7 and the wireless transmission module 43 thereon. The wireless transmission module 43 on the magnetic ring 6 and the wireless transmission module 43 inside the mounting box 41 are wirelessly connected. The hovering control module 44 controls the operation of the drive component in the clamping member 7 through the wireless transmission module 43.

[0064] When the current regulating module 42 outputs a current in the first direction, a repulsive force is generated between the magnetic ring 5 and the magnetic ring 6, and the direction of the repulsive force is the same as the direction of gravity.

[0065] The user blows air into the bottom of the transparent tube 11, generating an upward airflow thrust. The magnetic ring 6 overcomes the repulsive force and gravity under the action of the airflow thrust, rises and suspends, realizing the exhalation training mode.

[0066] When the current regulating module 42 outputs a second-direction current, an attractive force is generated between the magnetic ring 5 and the magnetic ring 6, and the direction of the attractive force is opposite to the direction of gravity.

[0067] The user inhales from the top of the transparent tube 11, generating an upward airflow drag force. The magnetic ring 6 overcomes gravity and rises and suspends under the combined action of the airflow drag force and suction force, thus realizing the inhalation training mode.

[0068] Working principle: At the start of training: the clamping part 7 is in the released state, the ball 73 can roll freely, and the magnetic ring 6 can slide flexibly inside the tube. During training: the airflow pushes the magnetic ring 6 upward, the ball 73 rolls along the guide groove 113, and the magnetic ring 6 rises smoothly to the equilibrium position. At the end of training: the hovering control module 44 issues a command, the wireless module on the magnetic ring 6 receives the signal, the drive unit starts, the turntable 77 rotates, the sliding pin 76 moves in the inclined groove 75, the movable rod 71 extends outward, the friction block 72 pushes out, presses the ball 73, the ball 73 is locked, and the position of the magnetic ring 6 is fixed. After the reading is completed: the reverse command is given, the friction block 72 retracts, the ball 73 is released, and the magnetic ring 6 falls back.

[0069] Suspension process: Airflow acts on magnetic ring 6, which is subjected to the combined force of airflow and magnetic force. Ball 73 rolls along guide groove 113, and magnetic ring 6 rises or falls smoothly, reaching the equilibrium position and suspending. Suspension locking process: Control system 4 issues a suspension command, magnetic ring 6 wireless transmission module 43 receives the signal, drive component (micro motor) starts, rotating shaft 74 drives turntable 77 to rotate, sliding pin 76 slides in inclined groove 75, sliding pin 76 drives movable rod 71 to move outward, friction block 72 extends along movable groove 61, friction block 72 presses against ball 73, ball 73 is locked, and magnetic ring 6 is fixed in position. Suspension release process: Control system 4 issues a release command, drive component rotates in the opposite direction, turntable 77 reverses, sliding pin 76 drives movable rod 71 to retract, friction block 72 retracts, ball 73 is released, and magnetic ring 6 can slide freely.

[0070] It adopts a composite structure of plastic frame and thin-walled permanent magnet, with a total weight of less than 15 grams, so even patients with weak muscle strength can blow it. The magnetic ring 26 has a built-in power supply module 45, which can perform the locking action without external wiring.

[0071] The magnetic ring 5 includes: an excitation coil 52 for generating magnetomotive force; a magnetic core 53 disposed inside the excitation coil 52 for enhancing and guiding the magnetic field; and a magnetic outer shell 51 covering the outside of the excitation coil 52, which together with the magnetic core 53 forms a closed magnetic circuit. The end face of the magnetic core 53 facing the magnetic ring 6 is conical or stepped, so that the electromagnetic force on the magnetic ring 6 at different displacement positions is basically constant.

[0072] Working principle: The current regulating module 42 outputs current, the excitation coil 52 generates a magnetic field, the magnetic core 53 gathers the magnetic field, the magnetic shell 51 guides the magnetic lines of force to form a closed loop, and the magnetic field acts on the magnetic ring 6, generating repulsive or attractive forces according to the direction of the current.

[0073] Exhalation mode: When a positive current is applied, magnetic ring 5 generates a N pole, which repels the N pole of magnetic ring 6, and magnetic ring 6 is subjected to a downward repulsive force.

[0074] Inhalation mode: When a reverse current is applied, magnetic ring 5 generates an S pole, which attracts the N pole of magnetic ring 6, and magnetic ring 6 is subjected to an upward attractive force.

[0075] Vent 111 maintains the air pressure balance inside the pipe, allowing for smooth airflow.

[0076] The visual scale lines include scale group one 12 and scale group two 13. Scale group one 12 corresponds to the blowing pressure value in the exhalation training mode, and scale group two 13 corresponds to the inhalation negative pressure value in the inhalation training mode.

[0077] Example 2:

[0078] This embodiment is basically the same as the previous embodiment, except that the inner wall of the transparent tube 11 and the surface of the magnetic ring 6 are coated with a hydrophobic and oleophobic coating, a ring-shaped filter membrane 112 is attached and fixed to the inner wall of the transparent tube 11 at the position corresponding to the air vent 111, and vertically distributed guide grooves 113 are opened on the inner wall of the transparent tube 11 at the positions corresponding to the positions of several balls 73.

[0079] Working principle: A filter membrane 112 is installed at the vent 111 to prevent external pollutants from entering the tube, which meets the hygiene requirements of medical equipment. The guide groove 113 ensures that the magnetic ring 6 always moves along the axis, avoiding deviation that could lead to increased friction or jamming. The hydrophobic and oleophobic coating makes it difficult for saliva to adhere, reducing bacterial growth and extending the cleaning cycle.

[0080] Complete work process:

[0081] Preparation phase: The user selects the working mode, the command is executed by the control system 4, the current regulation module 42 outputs a positive current to the magnetic ring 5, the magnetic ring 5 generates a N pole magnetic field, which generates a downward repulsive force on the magnetic ring 6.

[0082] Training phase: The user blows air into the connecting air tube 2. The airflow passes through the base 3 and the interface 142 and enters the bottom of the transparent tube 11. The airflow pushes the magnetic ring 6 upward. The ball bearing 73 of the magnetic ring 6 rolls along the guide groove 113 and rises steadily. The upward airflow force, downward magnetic repulsion force and gravity on the magnetic ring 6 reach a balance. The magnetic ring 6 is suspended at a certain scale position. The scale group 12 on the wall of the transparent tube 11 displays the corresponding pressure value.

[0083] End stage: The user stops blowing air, the airflow disappears, and the medical staff issues a locking command through the hovering control module 44 in the control system 4. The wireless transmission module 43 sends the command to the magnetic ring 6, the micro motor of the magnetic ring 6 starts, the turntable 77 rotates, the friction block 72 extends to press the ball 73, the position of the magnetic ring 6 is locked, and the medical staff reads and records the scale value.

[0084] Reset phase: Control system 4 issues a release command, the micro motor of magnetic ring 2 6 reverses, friction block 72 retracts, ball 73 is released, and magnetic ring 2 6 falls back to the bottom under the action of gravity, waiting for the next training.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
