Description

Technical Field

[0001] This invention relates to the field of respiratory medical device technology, specifically to a medical respiratory lung function recovery training device. Background Technology

[0002] Breathing trainers, as specialized medical devices, have been widely used in the field of pulmonary function rehabilitation in recent years. Through specific training modes, they help improve lung function, strengthen respiratory muscles, improve respiratory efficiency, and play an auxiliary role in the treatment of certain respiratory diseases. Patients with chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), bronchial asthma, interstitial lung disease, and bronchiectasis often face problems such as shortness of breath and decreased exercise tolerance due to impaired lung function or weakened respiratory muscles. Breathing trainers, by providing adjustable resistance, help patients gradually strengthen their inspiratory or expiratory muscles, which has a positive effect on improving shortness of breath and increasing daily activity tolerance. Furthermore, regular use of breathing trainers can promote lung ventilation, reduce residual gas in the lungs, and thus optimize lung function. Therefore, breathing trainers play a crucial role in pulmonary function recovery training in respiratory medicine.

[0003] While existing respiratory trainers have achieved some success in helping patients restore lung function, they still have some significant shortcomings. Firstly, most existing respiratory trainers require manual resistance adjustment and cannot adaptively adjust to the patient's specific needs based on their breathing patterns. This leads to patients potentially needing to frequently adjust the trainer during training, which is not only cumbersome but may also negatively impact training effectiveness. Secondly, because they cannot monitor patients' respiratory data in real time, traditional respiratory trainers cannot accurately assess the patient's lung function recovery status or evaluate deficiencies in respiratory intensity, respiratory rate, and inspiratory and expiratory time. Consequently, they cannot provide targeted, individualized training plans and often fail to achieve effective respiratory function training. This is similar to the use of ventilators in clinical practice, where optimal respiratory parameters need to be designed based on different disease types and the patient's physical condition to achieve the most effective assisted breathing, thereby improving oxygenation and carbon dioxide retention. To achieve optimal training results, progressive training is necessary, which also requires monitoring respiratory data. Only when these two aspects guide and match each other can effective training be achieved. Otherwise, excessive and forced training often backfires and may cause complications such as spontaneous pneumothorax and muscle fatigue, worsening respiratory conditions, affecting training effectiveness, and leading to training interruption. When assessing a patient's rehabilitation progress, doctors or rehabilitation therapists often rely solely on the patient's subjective feelings and traditional pulmonary function tests, which to some extent limits the accuracy and effectiveness of rehabilitation training. In summary, while existing respiratory trainers have achieved some success in helping patients restore lung function, they still have shortcomings such as the inconvenience of manually adjusting resistance and the inability to monitor patient respiratory data in real time. To solve these problems, a more intelligent and efficient respiratory trainer needs to be developed to better meet the rehabilitation needs of patients. Therefore, developing a respiratory trainer that can adaptively adjust resistance, monitor patient respiratory data in real time, and provide feedback on lung function recovery is of great significance for improving the targeting and effectiveness of rehabilitation training. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a medical respiratory pulmonary function recovery training device that adaptively adjusts resistance based on the patient's exhalation or inhalation, monitors the patient's respiratory data in real time, and provides feedback on the recovery status of pulmonary function.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A medical respiratory lung function recovery training device, including a respiratory trainer, the respiratory trainer being signal-connected to a respiratory training system, the respiratory trainer including an upper base and a lower base, the upper base being detachably connected to a catheter assembly;

[0006] The upper base is equipped with an air intake adjustment component. Several air tanks are fixedly connected to the bottom of the upper base. The end of each air tank away from the upper base is fixedly connected to the top of the lower base. Each air tank is equipped with a buoyancy ball. A judgment component is provided at the end of each air tank near the upper base. An air intake tube is connected between the judgment component and the air intake adjustment component. The air intake adjustment component and the air tank are connected through the interior of the upper base.

[0007] An adjustment tank is provided between the upper base and the lower base. An exhalation adjustment component is provided at one end of the adjustment tank near the upper base. An exhalation tube is connected between the judgment component and the exhalation adjustment component. An exhalation channel component is provided at the bottom of the tank. The exhalation channel component and the exhalation adjustment component are connected through the interior of the adjustment tank and the lower base.

[0008] The judgment component is used to assess the patient's breathing status when the buoyancy ball is compressed as it rises inside the air canister; the inspiratory regulation component is used to set resistance during the patient's inhalation to reduce the amount of air entering the channel to the upper base; the expiratory regulation component is used to set resistance during the patient's exhalation to reduce the amount of gas entering the regulating canister and the lower base; the expiratory channel component is used to provide a channel for the buoyancy ball to rise during exhalation; and the catheter component is used to provide channels for both inhalation and exhalation when the patient uses the breathing trainer for lung function recovery training.

[0009] The technical principles of the above solution are as follows:

[0010] When the patient inhales, air enters the air canister through the tubing assembly, causing the buoyancy ball to rise. As the buoyancy ball rises, it compresses the judgment component, which is connected to the inspiratory regulation component via the inspiratory tube. This component transmits the respiratory signal to the inspiratory regulation component, which dynamically adjusts the resistance during inhalation based on the signal from the judgment component. By reducing the amount of air entering the channel of the upper base 1, different levels of inspiratory training are simulated, enhancing the patient's inspiratory muscle strength.

[0011] When the patient exhales, air enters the canister through the expiratory channel component, causing the buoyancy ball to rise and compress the judgment component. The judgment component, connected to the expiratory regulation component via the expiratory tube, transmits an expiratory signal. The expiratory regulation component, in turn, adjusts the resistance during exhalation based on the signal from the judgment component. By reducing the amount of gas entering the regulating canister and lower base, this helps the patient expel more air from their lungs, improving ventilation.

[0012] The breathing training system records the patient's breathing data in real time, including respiratory rate, breathing depth, inspiratory resistance, and expiratory resistance.

[0013] The above approach has the following beneficial effects:

[0014] 1. In this design, the inspiratory and expiratory regulation components dynamically adjust the resistance during inhalation and exhalation based on signals transmitted by the judgment components. This adaptive adjustment mechanism ensures the targeted and effective nature of the training, avoiding the discomfort or overtraining that may result from traditional fixed resistance training. By simulating inhalation training of varying difficulty, the device can enhance the strength of the patient's inspiratory muscles (such as the diaphragm and intercostal muscles). This is significant for improving respiratory function and increasing vital capacity. The expiratory regulation component helps patients better coordinate their expiratory muscles during exhalation, promoting the full expulsion of air from the lungs and thus improving ventilation.

[0015] 2. This program, based on real-time respiratory data feedback, allows the respiratory training system to record the patient's respiratory data in real time, including key indicators such as respiratory rate, respiratory depth, inspiratory and expiratory resistance, inspiratory and expiratory time, etc. This data provides doctors or rehabilitation therapists with accurate assessment criteria, helping to develop and adjust personalized rehabilitation plans.

[0016] 3. In this solution, the conduit assembly of the equipment is detachable, which facilitates cleaning and disinfection. When replacing, only the conduit assembly needs to be disassembled, thus reducing costs.

[0017] Furthermore, each component includes a balloon fixedly connected to the bottom of the upper base. Each balloon is located inside a corresponding air tank. The output port of each balloon is connected to the inhalation tube and the exhalation tube, respectively. Each balloon is equipped with a first valve and a second valve at the connection point between the balloon and the inhalation tube and the exhalation tube. Both the first valve and the second valve are connected to the breathing training system signal.

[0018] Beneficial effects: As the buoyancy ball rises within the air tank, it immediately compresses the balloon, triggering the transmission of inhalation and exhalation signals. This highly sensitive design ensures the device accurately senses every breath the patient takes. Using a balloon as the sensing component simplifies the design compared to other complex mechanical or electronic sensors. This not only reduces manufacturing costs but also improves the device's reliability and durability.

[0019] Furthermore, the intake adjustment assembly includes a support plate fixedly connected to the inner wall of the upper base. An exhaust one-way valve is rotatably connected to the side of the support plate away from the adjustment tank. A first air hole corresponding to the exhaust one-way valve is opened on the support plate. A first gear plate is sleeved on the outside of the exhaust one-way valve. A first fixed plate is coaxially rotatably connected to the first gear plate. An intake adjustment chamber is provided at the lower part of the first fixed plate. The intake adjustment chamber is connected to the intake pipe. A first pawl is engaged on one side of the first gear plate. The end of the first pawl away from the first gear plate is coaxially rotatably connected to the first fixed plate. A first fixed rod is provided in the intake adjustment chamber. A first transmission rod is rotatably connected to the first fixed rod. A first cam and a first fan are coaxially fixedly connected to the first transmission rod. The first cam and the side of the first pawl away from the first gear plate rotate intermittently in cooperation.

[0020] Beneficial effects: The intermittent rotational connection between the first cam and the first pawl enables precise control over the opening timing of the exhaust check valve. When the first cam rotates to contact the first pawl, it pushes the pawl to rotate, which in turn adjusts the opening of the exhaust check valve via a gear transmission, thereby dynamically regulating the resistance during inhalation. This design ensures the accuracy and continuity of resistance adjustment. The inhalation adjustment component can simulate inhalation training of varying difficulty, allowing patients to exercise their respiratory muscles to different degrees by adjusting the resistance. This personalized training method helps improve patients' respiratory function and endurance.

[0021] Furthermore, the exhalation regulating assembly includes an intake one-way valve rotatably connected to the bottom of the upper base. The upper base has a second air hole corresponding to the intake one-way valve. A second gear plate is sleeved on the outside of the intake one-way valve. A second fixed plate is rotatably connected to the second gear plate. An exhalation regulating chamber is provided at the lower part of the second fixed plate. The exhalation regulating chamber is connected to the exhalation tube. A second pawl is engaged on one side of the second gear plate. The end of the second pawl away from the second gear plate is rotatably connected to the second fixed plate. A second fixed rod is provided in the exhalation regulating chamber. A second transmission rod is rotatably connected to the second fixed rod. A second cam and a second fan are coaxially fixedly connected to the second transmission rod. The second cam and the side of the second pawl away from the second gear plate rotate intermittently in cooperation.

[0022] Angle sensors are installed on both the first and second gear discs, and both angle sensors are connected to the breathing training system signal.

[0023] Beneficial Effects: The expiratory regulation component, through the intermittent rotational connection between the second cam and the second pawl, achieves precise control over the opening timing of the one-way inlet valve, thereby dynamically adjusting the resistance during exhalation. This design allows the device to automatically adjust the expiratory resistance based on the patient's expiratory force and frequency, ensuring training effectiveness. The expiratory regulation component can simulate expiratory training of varying difficulty, adjusting the resistance to provide different levels of exercise for the patient's expiratory muscles. This personalized training method helps improve the patient's expiratory function and endurance. As training progresses, the patient's expiratory muscle strength gradually increases. The expiratory regulation component can gradually increase the resistance according to the patient's actual condition, ensuring continuous improvement in training effectiveness.

[0024] Angle sensors are installed on both the first and second gear discs. These sensors are connected to the breathing training system and can monitor the rotation angle of the discs in real time. By analyzing this data, the breathing training system can accurately calculate the patient's respiratory rate, breathing depth, and changes in resistance during inspiration and expiration, providing doctors or rehabilitation therapists with accurate assessment data.

[0025] Furthermore, each of the exhalation channel components includes an exhalation port that is fixedly connected to the top of the lower base and located inside the air canister. The exhalation port is connected to the interior of the lower base. The top of the lower base is also fixedly connected to several grippers for holding the corresponding buoyancy ball so that the buoyancy ball remains stable in a static state.

[0026] Beneficial effects: The grippers fixedly connected to the top of the lower base are used to hold the buoyancy ball, keeping it stable when stationary. This prevents the buoyancy ball from moving randomly due to gravity or airflow, ensuring the accuracy of the buoyancy ball's position during training. Although the buoyancy ball is stably controlled by the grippers when stationary, it rises through the airflow at the exhalation port when the patient exhales, triggering the expiratory regulation component.

[0027] Furthermore, the conduit assembly includes an air duct connected to the side of the upper base near the regulating tank. The upper base has a threaded hole, and the outer wall of the connection between the air duct and the upper base has a threaded groove corresponding to the threaded hole. The air duct is threadedly connected to the upper base, and an exhalation nozzle is detachably connected to the end of the air duct away from the upper base.

[0028] Beneficial Effects: The air tube and upper base are connected by a threaded connection. The threaded groove on the outer wall of the air tube fits tightly with the threaded hole on the upper base, ensuring a stable connection. This connection method is not easily loosened by vibration or external force, thus ensuring the continuity and safety of breathing training. As the component that comes into direct contact with the patient, the hygiene of the exhalation nozzle is crucial. The detachable design allows for easy removal of the exhalation nozzle for thorough cleaning and disinfection, ensuring the hygiene and safety of training. The detachable exhalation nozzle can be replaced with different types according to the patient's specific needs or training plan. For example, patients requiring higher resistance training can choose an exhalation nozzle with a smaller opening; while beginners or patients requiring easier training can choose an exhalation nozzle with a larger opening.

[0029] Furthermore, an airbag is attached to the exhalation nozzle to fit the patient's face, and straps are provided on both sides of the airbag.

[0030] Beneficial effects: The airbag is made of soft and elastic material, which can closely conform to the patient's facial contours, effectively reducing air leakage. The strap design makes the airbag easy to put on and take off without complicated procedures. This helps save time for medical staff and improves work efficiency.

[0031] Furthermore, both the exhaust check valve and the intake check valve are equipped with gas flow meters, which are connected to the breathing training system via signal.

[0032] Beneficial effects: Gas flow meters can measure the flow rate of gas through a one-way valve in real time and accurately, including the flow rate during inhalation and exhalation. This provides doctors or rehabilitation therapists with accurate patient respiratory data, helping to assess the patient's respiratory function and training effectiveness. Through signal connection with a respiratory training system, the gas flow meter can instantly feed back the measured data to the system. The system can then automatically adjust training parameters, such as expiratory resistance and training time, based on this data to meet the patient's personalized training needs.

[0033] Furthermore, both the outlet check valve and the inlet check valve are equipped with external knobs for manually resetting the inlet and outlet channels of the outlet check valve and the inlet check valve.

[0034] Beneficial effects: In its initial state, the exhaust and intake check valves can be easily reset using the rotary dial. This operation is not only simple and convenient but also quickly restores the breathing trainer to its initial state, preparing it for airtightness verification. The rotary dial's reset function ensures that the check valves are in the correct position before each use, thus avoiding leaks caused by improper valve positioning.

[0035] Furthermore, the breathing training system includes a receiving module, a monitoring and feedback module, a testing module, an analysis module, and a data recording module;

[0036] The receiving module receives data from the gas flow meter and the angle sensor and transmits it to the monitoring feedback module, the verification module, and the analysis module, respectively.

[0037] The monitoring feedback module monitors whether the patient experiences insufficient respiratory power or airway obstruction during exhalation or inhalation, as reported by the gas flow meter, and feeds this information back to the data recording module. Let the real-time flow sequence collected by the gas flow meter be Q(t), and the sampling time window be T. The flow fluctuation variance is then used as a reference.

[0038]

[0039] in For the window mean, if >Empirical thresholds set by the monitoring and feedback module If so, it is determined that the patient's breathing is abnormally fluctuating during exhalation or inhalation;

[0040] The inspection module is used to inspect the airtightness of the breathing trainer by receiving gas flow meter information from the receiving module;

[0041] The analysis module is used to obtain the angle measured by the angle sensor when the outlet check valve (25) or the inlet check valve (23) rotates, and then calculates the resistance set after the outlet check valve (25) or the inlet check valve (23) rotates, and the real-time resistance model. The specific calculation method is as follows:

[0042]

[0043]

[0044] In the formula, N represents the rotation angle of the outlet check valve (25) or the inlet check valve (23) as measured by the angle sensor, and N is the number of blocking blocks in the outlet check valve (25) or the inlet check valve (23). The cross-sectional area when the exhaust check valve (25) or the intake check valve (23) is fully open;

[0045] The measured angle was compared with the set resistance data, and the patient's expiratory or inspiratory time was obtained through a gas flow meter to analyze the patient's lung breathing condition. Specifically:

[0046]

[0047] in, The respiratory work index is the number of breaths a patient takes in a single breath. This is expressed as the total duration of the patient's exhalation or inhalation as obtained by the gas flow meter, and... The data is transmitted to the data recording module;

[0048] The data recording module is used to record data from the monitoring feedback module showing that patients cannot train normally when using the breathing trainer due to their own problems. The data recording module is also used to record the resistance of the outflow one-way valve (25) or inflow one-way valve (23) when the patient is using the breathing trainer normally, as well as the patient's exhalation or inhalation time recorded by the gas flow meter to analyze the patient's lung breathing data. The module archives these data and can call them up at any time to analyze the recovery of the patient's lung breathing. The data recording module has a built-in time series trend model to store historical datasets. Where k represents the number of training iterations. Let the average resistance be the resistance during the k-th training iteration. The total duration of exhalation or inhalation during the k-th training session. This represents the peak flow rate during the k-th training iteration.

[0049] Beneficial Effects: The monitoring and feedback module receives real-time data from the gas flow meter, quickly identifying whether the patient experiences insufficient respiratory power or airway obstruction during exhalation or inhalation. This immediate monitoring and feedback mechanism helps doctors or rehabilitation therapists promptly detect respiratory disturbances and take appropriate adjustments, ensuring the safety and effectiveness of training. The verification module, by receiving information from the gas flow meter, accurately verifies the airtightness of the breathing trainer. This function is crucial before each training session, ensuring that the trainer will not affect training effectiveness or patient safety due to air leakage during training. A good airtight seal is the foundation for the stable operation of the breathing training system. The analysis module combines data from the angle sensor and gas flow meter to deeply analyze the patient's lung breathing. By adjusting the resistance of the outlet or inlet one-way valve, the system can simulate different breathing conditions, thereby assessing the patient's respiratory function and endurance. This personalized analysis helps doctors develop more precise training plans for patients, maximizing training effectiveness. The data recording module comprehensively records various data from the patient during training, including situations where normal training is impossible due to individual issues and recovery progress when using the trainer normally. This data provides doctors with valuable reference information, helping them to more accurately assess patients' recovery progress and adjust treatment plans. At the same time, the data records also enable long-term follow-up of patients' recovery.

[0062] The following detailed description illustrates the specific implementation method:

[0063] Example 1:

[0064] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: A medical respiratory lung function recovery training device includes a respiratory trainer, which is signal-connected to a respiratory training system. The respiratory trainer includes an upper base 1 and a lower base 5, and the upper base 1 is detachably connected to a catheter assembly.

[0065] The upper base 1 is equipped with an air intake adjustment component. Several air canisters 3 are snapped together at the bottom of the upper base 1.

[0071] Angle sensors are provided on both the first toothed disc 26 and the second toothed disc 22, and the angle sensors are both connected to the breathing training system signal.

[0072] Each exhalation channel assembly includes an exhalation port 13 welded to the top of the lower base 5 and located inside the air tank 3. The exhalation port 13 is connected to the interior of the lower base 5. The top of the lower base 5 is also welded with several grippers 12 for holding the corresponding buoyancy ball 4 so that the buoyancy ball 4 remains stable in a static state.

[0073] Both the exhaust check valve 25 and the intake check valve 23 are equipped with gas flow meters, and the gas flow meters are connected to the breathing training system signal.

[0074] The specific implementation process is as follows: The patient uses a breathing trainer for lung function recovery training. First, the patient inserts the end of the catheter assembly away from the upper base 1 into their mouth. When the patient inhales, air enters the upper base 1 through the catheter assembly and then enters the air tank 3 through the one-way valve 25. The buoyancy ball 4 rises in the air tank 3 due to the airflow generated by inhalation, squeezing the balloon 2. The balloon 2 is made of medical-grade elastic material and can be precisely squeezed when the buoyancy ball rises, triggering the transmission of airflow signals. During the patient's continuous inhalation, the first valve opens, and the gas in the balloon 2 is squeezed into the inhalation regulating chamber 28, causing the gas entering the inhalation regulating chamber 28 to blow the first fan 29 to rotate. The first fan 29 rotates through the first transmission rod 30, causing the first cam 32 to intermittently contact the first pawl 33. The first pawl 33 is lifted by the first cam 32, and the output shaft part of the first pawl 33 disengages from the engaging gear of the first gear plate 26 and meshes with the adjacent gear of this engaging gear. When the first cam 32 rotates to the recessed position, the first pawl 33... When the pawl 33 loses its support and falls, it engages with the recess of the first cam 32. The output shaft of the first pawl 33 pulls the gear it meshes with as the first pawl 33 falls, thereby driving the first gear plate 26 to rotate. During the reciprocating motion of the first cam 32, the first pawl 33 pulls the first gear plate 26 to rotate intermittently. At this time, the first gear plate 26 drives the exhaust one-way valve 25 to rotate. The exhaust one-way valve 25 contains several blocking blocks to increase the resistance when the patient inhales. This process is repeated until the patient can no longer inhale and lift the buoyancy ball 4 in the air canister 3.

[0075] When the patient exhales, air enters the upper base 1 through the catheter assembly. Since the outlet one-way valve 25 only allows gas to flow from left to right, the air, after entering the upper base 1, only enters the regulating tank 10 through the inlet one-way valve 23, and then blows the buoyancy ball 4 up through the exhalation port 13. The buoyancy ball 4 rises within the air tank 3 due to the airflow at the bottom, compressing the balloon 2. During the patient's continuous exhalation, the second valve opens and the first valve closes, compressing the gas inside the balloon 2 to regulate the exhalation. The gas entering the expiratory regulating chamber 15 blows the second fan 16 to rotate. The second fan 16 rotates through the second transmission rod 17, causing the second cam 19 to intermittently contact the second pawl 21. The second pawl 21, through the reciprocating motion of being pushed up by the second cam 19, pulls the second gear plate 22 to rotate intermittently. At this time, the second gear plate 22 drives the intake one-way valve 23 to rotate, thereby increasing the resistance when the patient exhales. This process is repeated until the gas exhaled by the patient can no longer blow up the buoyancy ball 4 in the air canister 3.

[0076] The gas flow meter can monitor the amount of gas passing through the patient during exhalation or inhalation and the time of exhalation or inhalation in real time. The angle sensor can obtain the scale of the rotation of the first toothed disc 26 and the second toothed disc 22 driven by the first pawl 33 and the second pawl 21, respectively, so that the breathing training system can obtain the resistance set by the current exhaust one-way valve 25 and intake one-way valve 23.

[0077] Example 2:

[0078] The difference from Embodiment 1 is that both the exhaust check valve 25 and the intake check valve 23 are provided with a knob for manually resetting the exhaust and intake channels of the exhaust check valve 25 and the intake check valve 23.

[0079] The specific implementation process is as follows: Before using the breathing trainer, manually rotate the knob. When the knob rotates, it will drive the connected exhaust one-way valve 25 and intake one-way valve 23 to rotate, so that the exhaust one-way valve 25 and intake one-way valve 23 are reset. Calculate whether the airflow through the exhaust one-way valve 25 and intake one-way valve 23 is normal under unobstructed conditions by blowing or inhaling, in order to check the airtightness of the breathing trainer and the tubing assembly.

[0080] Example 3:

[0081] As attached Figure 1 As shown, the difference from Embodiment 2 is that the catheter assembly includes an air tube 9 connected to the side of the upper base 1 near the regulating tank 10. The upper base 1 has a threaded hole, and the outer wall of the connection between the air tube 9 and the upper base 1 has a threaded groove corresponding to the threaded hole. The air tube 9 is threadedly connected to the upper base 1, and an exhalation nozzle 8 is detachably connected to the end of the air tube 9 away from the upper base 1. An air bag 7 for conforming to the patient's face is fitted onto the exhalation nozzle 8, and straps 6 are provided on both sides of the air bag 7.

[0082] The specific implementation process is as follows: For patients who have difficulty holding the breathing trainer, the straps 6 can be tied to both sides of the patient's face, and the exhalation nozzle 8 can be placed in the patient's mouth. The breathing trainer is placed in a horizontal position, allowing the patient to practice exhaling or inhaling. The air bag 7 is made of a soft and elastic material, which can closely conform to the patient's facial contours and effectively reduce air leakage. The design of the straps 6 makes the air bag 7 easy to put on and take off without complicated procedures. This helps save time for medical staff and improves work efficiency.

[0083] Example 4:

[0084] The difference from Example 3 is that, as Figure 5 , Figure 6 and Figure 7 As shown, the breathing training system includes a receiving module, a monitoring and feedback module, a testing module, an analysis module, and a data recording module;

[0085] The receiving module receives data from the gas flow meter and the angle sensor and transmits it to the monitoring feedback module, the verification module, and the analysis module, respectively.

[0086] The monitoring feedback module monitors whether the patient experiences insufficient respiratory power or airway obstruction during exhalation or inhalation, as reported by the gas flow meter, and feeds this information back to the data recording module. Let the real-time flow sequence collected by the gas flow meter be Q(t), and the sampling time window be T. The flow fluctuation variance is then used as a reference.

[0087]

[0088] in For the window mean, if >Empirical thresholds set by the monitoring and feedback module If so, it is determined that the patient's breathing is abnormally fluctuating during exhalation or inhalation;

[0089] The inspection module is used to inspect the airtightness of the breathing trainer by receiving gas flow meter information from the receiving module;

[0090] The analysis module is used to obtain the angle measured by the angle sensor when the outlet check valve (25) or the inlet check valve (23) rotates, and then calculates the resistance set after the outlet check valve (25) or the inlet check valve (23) rotates, and the real-time resistance model. The specific calculation method is as follows:

[0091]

[0092]

[0093] In the formula, N represents the rotation angle of the outlet check valve (25) or the inlet check valve (23) as measured by the angle sensor, and N is the number of blocking blocks in the outlet check valve (25) or the inlet check valve (23). The cross-sectional area when the exhaust check valve (25) or the intake check valve (23) is fully open;

[0094] The measured angle was compared with the set resistance data, and the patient's expiratory or inspiratory time was obtained through a gas flow meter to analyze the patient's lung breathing condition. Specifically:

[0095]

[0096] in, The respiratory work index is the number of breaths a patient takes in a single breath. This is expressed as the total duration of the patient's exhalation or inhalation as obtained by the gas flow meter, and... The data is transmitted to the data recording module;

[0097] The data recording module is used to record data from the monitoring feedback module showing that patients cannot train normally when using the breathing trainer due to their own problems. The data recording module is also used to record the resistance of the outflow one-way valve (25) or inflow one-way valve (23) when the patient is using the breathing trainer normally, as well as the patient's exhalation or inhalation time recorded by the gas flow meter to analyze the patient's lung breathing data. The module archives these data and can call them up at any time to analyze the recovery of the patient's lung breathing. The data recording module has a built-in time series trend model to store historical datasets. Where k represents the number of training iterations. Let the average resistance be the resistance during the k-th training iteration. The total duration of exhalation or inhalation during the k-th training session. This represents the peak flow rate during the k-th training iteration.

[0098] The specific implementation process is as follows: Before using the breathing trainer, manually rotate the knob. Rotating the knob will cause the connected outlet one-way valve 25 and inlet one-way valve 23 to rotate, resetting them. Then, calculate the airflow through the outlet and inlet one-way valves 25 and 23 under unobstructed conditions by blowing or inhaling to check the airtightness of the breathing trainer and tubing assembly. Before training, the patient manually rotates the knob to reset the one-way valves and triggers the gas flow meter by blowing / inhaling. The test module compares the flow rate with the standard value to determine if the airway thread connection and the exhalation nozzle seal are good.

[0099] When the patient inhales, the airflow enters the upper base 1 through the air guide tube 9, passes through the one-way valve 25, and enters the air tank 3. The buoyancy ball 4 rises and compresses the balloon 2, opening the first valve. The gas inside the balloon drives the first fan 29 in the inhalation adjustment chamber to rotate. At this time, the first cam 32 drives the first pawl 33 to pull the first gear 26 to rotate, changing the opening of the one-way valve and increasing the inhalation resistance. An angle sensor monitors the rotation angle of the first gear 26 in real time, corresponding to the resistance adjustment scale; the gas flow meter in the one-way valve 25 records the inhalation flow rate and time.

[0100] When the patient exhales, the airflow enters the regulating tank 10 through the inlet one-way valve 23, inflating the buoyancy ball 4 and squeezing the balloon 2. The second valve opens, and the gas pushes the second fan 16 in the exhalation regulating chamber. The second cam 19 drives the second pawl 21 to adjust the second gear disc 22, changing the opening degree of the inlet one-way valve. An angle sensor monitors the rotation angle of the second gear disc 22; the gas flow meter in the inlet one-way valve 23 records the expiratory flow rate and time.

[0101] The receiving module receives the flow rate and time from the gas flow meter in real time, as well as the signal of the toothed disc rotation angle monitored by the angle sensor. The receiving module transmits flow data to the monitoring feedback module for respiratory abnormality judgment; transmits flow data to the inspection module for sealing test; and transmits angle and flow data to the analysis module for resistance calculation and respiratory function analysis.

[0102] The monitoring and feedback module analyzes the variance of flow fluctuations to identify insufficient respiratory power (flow consistently below the threshold) or airway obstruction (sudden and large fluctuations in flow). When an abnormality is detected, such as excessively rapid inspiratory rate or excessively short expiratory time, a feedback signal is generated through a built-in algorithm, which can trigger hardware adjustments to temporarily reduce the opening of the one-way valve. During training, the testing module monitors flow stability in real time. If flow fluctuations occur that are not caused by respiratory actions, it is identified as a device leak and an alert is issued.

[0103] The analysis module calculates the current inspiratory / expiratory resistance in real time based on the mapping relationship between the toothed disc rotation angle data from the angle sensor and the one-way valve opening (e.g., each 5° rotation corresponds to a 1-level increase in resistance). Combined with the flow-time data from the gas flow meter, it calculates the work of breathing index, i.e., the energy consumed by breathing per unit time, to assess the patient's respiratory muscle endurance. Simultaneously, based on historical data, such as the resistance adaptation during the previous three training sessions, it automatically adjusts the initial resistance for the next training session using a progressive training algorithm, increasing the resistance by 1-2 levels with each training session.

[0104] After a patient completes a breathing training session, the data recording module records the resistance adjustment trajectory and flow-time waveform for each training session; it also records the patient's pulse oximetry and subjective fatigue level (Borg score) simultaneously, automatically linking them with the training data; and generates a rehabilitation trend report, such as a correlation analysis between the weekly increase in resistance and the improvement in oxygen saturation, providing doctors with a quantitative basis for adjusting the training plan.

[0105] The exhalation nozzle is made of silicone, and the airbag is designed to fit the face, reducing air leakage and improving wearing comfort. The strap design makes it easy for patients to fix the device, especially suitable for patients who have difficulty holding it, thus expanding the applicability of the device.

[0106] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
