Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to an oscillating expiratory positive pressure device with airway clearing technology. Background Art

[0002] In the medical field, airway clearance refers to the removal of secretions and foreign matter in the respiratory tract through a series of means to maintain the patency of the respiratory tract and normal gas exchange function. This process is essential for maintaining the health of the respiratory system, especially in patients with chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma and lung infections. Airway clearance is mainly achieved by promoting ciliary movement, improving mucus transport, increasing airway pressure and accelerating gas flow. Cilia are tiny hair-like structures on the surface of airway epithelial cells. They can swing rhythmically to push secretions and foreign matter adhering to the airway wall to the larynx, and then expel them from the body through coughing or swallowing. This is an important part of the natural airway clearance mechanism. However, in the disease state, ciliary function may be impaired, secretion retention increases, leading to airway obstruction and increased risk of infection.

[0003] Traditional airway clearance techniques mainly include physical therapy such as postural drainage and chest physical therapy. Although these methods help to clear secretions to a certain extent, they are often limited by factors such as the patient's physical condition, the therapist's professional skills and treatment time, and their effects are not always ideal.

[0004] In recent years, with the continuous development of medical device technology, airway clearance devices based on the principle of oscillating expiratory positive pressure have gradually attracted attention. This type of device simulates the cilia swinging in the airway during the natural breathing process of the human body to generate periodic oscillating airflow, thereby helping to reduce the viscoelasticity of secretions in the airway, promote the movement of secretions to the large airways and eventually excrete them from the body. However, most existing oscillating expiratory positive pressure devices use a fixed-frequency oscillation mode and cannot be dynamically adjusted according to the patient's actual exhalation process and airway status, resulting in limited treatment effects and possible discomfort to patients due to frequency mismatch.

[0005] In addition, the fixed-frequency oscillation mode also ignores the differences between patients at different stages of treatment or disease progression. For example, as the treatment progresses, the patient's airway condition may improve or worsen, and the fixed oscillation frequency cannot flexibly respond to these changes, thus limiting the maximization of the treatment effect. In addition, there are differences in respiratory physiological characteristics between different patients, such as expiratory flow, expiratory time, etc. These differences put higher requirements on the adaptability of the oscillation frequency.

[0006] In view of the above problems, the medical field urgently needs an oscillating expiratory positive pressure device with airway clearance technology that can monitor the patient's exhalation process in real time and automatically adjust the oscillation frequency. Such a device can better adapt to the individual differences and changes in the condition of patients, improve the treatment effect and patient comfort, and reduce the risks during the treatment process. Summary of the invention

[0007] To solve the above problems, the present invention aims to provide an oscillating expiratory positive pressure device with a more intelligent and personalized airway clearance technology, which monitors the patient's exhalation process in real time and automatically adjusts the oscillation frequency according to the monitoring data to ensure that the oscillating airflow always matches the patient's exhalation process, thereby improving the treatment effect and the patient's comfort.

[0008] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an oscillating expiratory positive pressure device of airway clearing technology, comprising a housing and a controller, wherein an air inlet cavity, a mounting cavity and an air outlet cavity are sequentially arranged inside the housing, an adjusting cavity is arranged on the top wall outside the mounting cavity, two sides of the mounting cavity are respectively connected with the air inlet cavity and the air outlet cavity, one side of the air inlet cavity is connected with an exhalation structure, a monitoring structure for real-time monitoring of the exhalation process is installed in the exhalation structure, an adjusting structure for adjusting the oscillation frequency according to real-time data provided by the monitoring structure is installed in the mounting cavity, and a plurality of air outlet holes are opened on the side wall of the air outlet cavity;

[0009] The adjusting structure includes a push plate, a screw is fixedly connected to one side of the push plate, the screw passes through the installation cavity and the adjusting cavity in sequence away from the push plate and extends to the outside of the adjusting cavity, a spring is sleeved on the part of the screw located in the installation cavity, one end of the spring is fixedly connected to the push plate, and the other end of the spring is fixedly connected to the inner top wall of the installation cavity, a collar is sleeved on the part of the screw located in the adjusting cavity, a moving part is outerly provided with the collar, the outer wall of the moving part is a worm structure, the moving part is matched with an adjusting power part, the adjusting power part is fixedly connected to the inner wall of the adjusting cavity, a feedback structure is threadedly matched with the part of the screw located in the outer side of the adjusting cavity, and the feedback structure is rotationally matched with the outer wall of the adjusting cavity;

[0010] The controller is connected to the monitoring structure, the adjusting power part and the feedback structure signal. The controller collects and analyzes the real-time monitoring data of the monitoring structure. The controller adjusts the power of the adjusting power part according to the real-time monitoring data of the monitoring structure. At the same time, the controller controls the feedback structure to give different types of feedback according to the movement of the screw, and the controller can correct the power of the adjusting power part according to the feedback result of the feedback structure.

[0011] The technical principle of the above scheme is as follows: the patient exhales through the exhalation structure, and the monitoring structure monitors the key parameters of the exhalation process in real time. As the patient exhales, the airflow enters the air inlet cavity and pushes the push plate up. The push plate rises to connect the air inlet cavity with the air outlet cavity, and the airflow enters the air outlet cavity and flows out from the air outlet. When the air pressure of the air inlet cavity and the air outlet cavity is balanced, the push plate descends under the action of the spring reset force to complete a cycle. The reciprocating motion of the push plate causes an oscillating airflow to be generated in the device, simulating the cilia swing and promoting the removal of secretions in the airway. The controller automatically adjusts the power part through algorithm analysis based on the real-time data provided by the monitoring structure. The rotation of the regulating power part drives the moving part to rotate up or down, and then generates different sizes of tightening force on the screw through the collar, affecting the rising speed and oscillation frequency of the push plate. The feedback structure cooperates with the rotation of the screw to give different forms of feedback (such as sound, light, etc.) according to the movement of the screw (i.e., the change of oscillation frequency).

[0012] The above scheme has the following beneficial effects:

[0013] 1. This solution monitors and automatically adjusts the oscillation frequency in real time. The device of the present invention can ensure that the oscillating airflow always matches the patient's exhalation process, thereby more effectively reducing the viscoelasticity of mucus, promoting the removal of secretions, and improving the treatment effect.

[0014] 2. The automatic adjustment mechanism of this solution avoids the discomfort that may be caused by the fixed frequency in traditional devices. By dynamically adjusting the oscillation frequency, the device of the present invention can better adapt to the individual differences of patients and the slight changes in the exhalation process, thereby improving the comfort of patients.

[0015] 3. The introduction of monitoring and feedback structures in this solution enables the device to detect and handle abnormal situations (such as abnormal airflow velocity, excessive airway resistance, etc.) in a timely manner. By issuing alarms and automatically adjusting the oscillation frequency, the risks during treatment are effectively reduced and the safety of patients is guaranteed. The feedback structure can give patients intuitive feedback based on the movement of the screw, helping them understand the progress of treatment and enhancing their sense of participation and comfort during treatment.

[0016] 4. As the core component of the whole device, the controller of this solution realizes the centralized control and management of monitoring data, regulating power parts and feedback structure. This intelligent management method not only improves the automation and work efficiency of the device, but also provides medical personnel with more convenient and accurate treatment methods.

[0017] Furthermore, the feedback structure includes a ring, and the screw and the ring form a ball screw structure. The ring is a hollow structure, and a speed sensor, a light component, a voice component and a speaker are installed inside the ring. The light component, the voice component and the speaker are all connected to the controller signal. The controller starts the corresponding component according to the feedback method of the feedback structure selected by the patient. At the same time, the controller adjusts the power of the light component, the voice component and the speaker according to the real-time data of the monitoring structure and the speed sensor.

[0018] Beneficial effects: The feedback structure provides a variety of feedback methods including visual (lighting component) and auditory (voice component and speaker). This allows patients to choose the appropriate feedback method according to their personal preferences or needs, increasing the flexibility and personalization of treatment. At the same time, the diverse feedback methods also help to improve patient participation and treatment experience. The speed sensor monitors the rotation speed of the ball screw (i.e., the screw and the ring) in real time, and this data directly reflects the adjustment of the oscillation frequency. Based on this real-time data and the patient's exhalation data obtained by the monitoring structure, the controller accurately adjusts the power of the light component, voice component and speaker. This real-time and precise adjustment mechanism ensures the accuracy and timeliness of feedback information, which helps patients better understand and cooperate with the treatment process. Through the flashing of the light component, the voice prompts of the voice component and the sound feedback of the speaker, the patient can intuitively perceive the changes in the oscillation frequency and the adjustment effect. This intuitive perception helps to enhance patients' confidence and compliance in treatment and improve the treatment effect.

[0019] Furthermore, the monitoring structure includes an airflow sensor and a pressure sensor. The airflow sensor is used to monitor the patient's expiratory airflow velocity in real time, and the pressure sensor is used to measure the change of airway resistance during exhalation. Both the airflow sensor and the pressure sensor are connected to the controller signal. The controller adjusts the power of the regulating power component according to the real-time monitoring data of the airflow sensor and the pressure sensor.

[0020] Beneficial effects: By monitoring the patient's expiratory airflow velocity and airway resistance changes in real time, the controller can obtain accurate data on the patient's breathing status. These data provide an accurate basis for adjusting the power parts, making the adjustment of the oscillation frequency more accurate and personalized, thereby improving the treatment effect. When abnormal data is detected (such as abnormal airflow velocity, excessive airway resistance, etc.), the controller can respond quickly to avoid potential risks by adjusting the power parts or other safety measures. This instant response mechanism helps to ensure the safety of patients and reduce risks during treatment. The precise monitoring and adjustment mechanism enables the device to better adapt to the patient's breathing needs and reduce discomfort caused by improper treatment. This patient-centered design concept helps to improve the patient's treatment experience and comfort and increase patient compliance with treatment.

[0021] Furthermore, the exhalation structure includes a mask with a breathing hole, a mounting ring fixedly connected to the breathing hole, a mouthpiece detachably connected to one side of the mounting ring, the other side of the mounting ring is connected to the air inlet cavity, the mouthpiece is connected to the air inlet cavity through the mounting ring, the monitoring structure is installed inside the air inlet cavity, and an anti-pressure sore component and a fixing component for fixing the mask are installed on the side of the mask close to the patient's skin.

[0022] Beneficial effects: The detachable connection design of the mouthpiece allows the selection of a suitable mouthpiece for installation according to the size of the patient's mouth. This personalized adaptation not only ensures a close fit between the mouthpiece and the patient's mouth, improving the seal and effect of the treatment, but also increases the patient's comfort and reduces treatment interruptions or resistance caused by discomfort. The detachable mouthpiece design allows for easy cleaning and replacement, effectively avoiding the risk of cross infection. After each patient's use, the mouthpiece can be easily removed for thorough cleaning and disinfection, ensuring safe use by the next patient.

[0023] The monitoring structure is installed inside the air inlet cavity and can directly obtain key data during the patient's exhalation process, such as airflow velocity, airway resistance, etc. This design improves the accuracy of monitoring, allowing the controller to make more precise adjustments based on real-time data, thereby optimizing the treatment effect. The anti-pressure sore component can effectively reduce the pressure of the mask on the skin and reduce the risk of pressure sores caused by wearing the mask for a long time. The setting of the fixed component ensures the stability of the mask during treatment and prevents the mask from falling off or leaking due to patient movement or activity. This not only ensures the continuity of treatment, but also avoids the situation where air leakage reduces the treatment effect or increases patient discomfort.

[0024] Furthermore, the anti-pressure sore component includes an outer ring, which is fixedly connected to the mask, and a first groove and a second groove are provided on the side of the outer ring close to the patient's skin, and a first airbag and a second airbag are respectively installed in the first groove and the second groove, and the first airbag and the second airbag are fixedly connected to a temperature sensor, and the first airbag and the second airbag are both provided with an air inlet and an air outlet, and the inlets are connected to a power part, and a one-way valve is installed on the air inlet and the air outlet, and the temperature sensor, the power part and the one-way valve are all connected to the controller signal, and the controller performs opening and closing instructions on the power part and the one-way valve according to the monitoring data of the temperature sensor.

[0025] Beneficial effects: Through the alternating inflation of the first and second airbags, the anti-pressure sore component effectively disperses the pressure of the mask on the skin, avoiding the risk of poor blood circulation and pressure sores caused by long-term single-point compression. This dynamic pressure distribution mechanism significantly improves the wearing comfort of patients and ensures the health of the skin during treatment. At the same time, the inflation of the airbag makes the mask body fit the patient's face more closely, effectively reducing air leakage and improving the sealing and effect of treatment.

[0026] Furthermore, the fixing component includes an elastic band, and through holes are provided on both sides of the outer ring. The two ends of the elastic band pass through the through holes on both sides of the outer ring respectively, wherein one end of the elastic band is fixedly connected to the outer ring, and the same side of the other end of the elastic band is fixedly connected with a child Velcro and a mother Velcro.

[0027] Beneficial effects: Through the combination of the sub-velcro and the parent Velcro, patients or medical staff can easily adjust the length of the elastic band to adapt to the head size and wearing needs of different patients. This flexible adjustment mechanism ensures that the mask will not be too tight to cause discomfort to the patient, nor too loose to affect the wearing effect and sealing. The soft material and moderate elasticity of the elastic band reduce the pressure and discomfort on the facial skin and improve the wearing comfort of the patient. Compared with traditional fixing methods, such as tight straps or hard frames, the elastic band has good elasticity and retraction force, can fit tightly on the patient's head, provide a stable fixing effect, and is more in line with the patient's physiological characteristics.

[0028] Furthermore, the regulating power part includes a motor, the motor is fixedly connected to the inner side wall of the regulating cavity, the motor output shaft is coaxially fixedly connected to a worm gear, and the worm gear is meshed with the moving part.

[0029] Beneficial effects: By adjusting the speed and direction of the motor, the adjustment components can be flexibly adjusted. Whether quick adjustment or fine tuning is required, it can be achieved by controlling the parameters of the motor. In addition, the meshing structure of the worm gear and the moving part also allows continuous adjustment within a certain range, meeting the use requirements in different scenarios. The introduction of the motor automates the adjustment process. Under the command of the controller, the motor can automatically start, stop and adjust the speed, thereby achieving precise control of the adjustment components. This automated operation not only improves work efficiency, but also reduces the manual operation burden of medical staff or patients, improves the convenience of use, and also ensures the stability and accuracy of the adjustment process.

[0030] Furthermore, it also includes an interactive module, which is used to preset parameters and view monitoring data in real time. The interactive module is connected to the controller signal, and the interactive module presets the parameters of the regulating power parts and the regulating parameters through the controller.

[0031] Beneficial effects: The interactive module provides users with an intuitive and easy-to-use operating interface, allowing patients or medical staff to easily preset the parameters of the power parts and the adjustment parameters. This user-friendly design reduces the difficulty of operation, improves the ease of use of the system, and makes it easy for more people to get started. By presetting parameters through the interactive module, users can customize it according to the specific conditions and needs of the patients. For example, adjust the inflation volume and pressure of the airbag according to the patient's facial contour and comfort requirements; adjust the parameters of the ventilator according to the patient's breathing habits and treatment effects, etc. This personalized customization function improves the pertinence and effectiveness of treatment and meets the needs of different patients.

[0032] Furthermore, it also includes a remote monitoring module, which is used to remotely monitor the working status of the device and the patient's usage. The remote monitoring module is connected to the controller signal. The remote monitoring module inputs the monitoring signal through the controller and issues corresponding control instructions.

[0033] Beneficial effects: The remote monitoring module can obtain real-time data on the device's working status and patient usage, such as the tightness of the mask, the pressure of the airbag, the patient's breathing rate, etc. These data are crucial for remote medical support and timely intervention, ensuring that medical staff can respond quickly when patients need help. The remote monitoring module enables medical staff to monitor and guide the use of patients at home, improving the feasibility and effectiveness of home care.

[0034] Furthermore, it also includes an early warning module, which is connected to the controller, the feedback structure and the remote monitoring module signal. When the monitoring structure detects abnormal data, the early warning module is activated by the controller to sound an alarm to remind the user to take corresponding measures. The early warning module sends out an alarm including but not limited to sound alarm, visual alarm, tactile alarm and remote notification.

[0035] Beneficial effects: When the monitoring structure detects abnormal data, such as abnormal patient breathing rate, mask leakage, etc., the early warning module can be immediately activated through the controller and sound an alarm. This instant alarm response mechanism can quickly remind users (including patients, family members and medical staff) to pay attention to abnormal situations, take timely countermeasures, and effectively avoid potential risks and adverse consequences. The early warning module provides a variety of alarm methods, including sound alarms, visual alarms, tactile alarms and remote notifications. This diversified alarm method ensures that users can receive alarm information in a timely manner in different scenarios. For example, in a noisy environment, the sound alarm may not be obvious enough, but the visual or tactile alarm can still work; for telemedicine scenarios, remote notifications become an indispensable means of communication.

[0036] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following is further described in detail through specific implementation methods:

[0049] Embodiment 1:

[0050] As attached Figures 1 to 7 As shown: an oscillating expiratory positive pressure device with airway clearing technology includes a shell 1 and a controller. The shell 1 is provided with an air inlet cavity 101, a mounting cavity 102 and an air outlet cavity 103 in sequence. The side wall of the air outlet cavity 103 is provided with a plurality of air outlet holes 105. An adjusting cavity 104 is provided on the outer top wall of the installation cavity 102, and the two sides of the installation cavity 102 are respectively connected with the air inlet cavity 101 and the air outlet cavity 103, and one side of the air inlet cavity 101 is connected with an exhalation structure, and a monitoring structure for real-time monitoring of the exhalation process is installed in the exhalation structure, and the exhalation structure includes a mask 201, and a breathing hole is opened on the mask 201, and a mounting ring 2 is fixedly connected to the breathing hole, and a mouthpiece 202 is detachably connected to one side of the mounting ring 2, and the other side of the mounting ring 2 is connected with the air inlet cavity 101, and the mouthpiece 202 is connected with the air inlet cavity 101 through the mounting ring 2, and the monitoring structure is installed inside the air inlet cavity 101, and a fixing component for fixing the mask 201 is installed on the side of the mask 201 close to the patient's skin (the fixing component in this embodiment is a strap).

[0051] The monitoring structure includes an airflow sensor and a pressure sensor. The airflow sensor is used to monitor the patient's expiratory airflow velocity in real time, and the pressure sensor is used to measure the change of airway resistance during exhalation. Both the airflow sensor and the pressure sensor are connected to the controller signal. The controller adjusts the power of the regulating power component according to the real-time monitoring data of the airflow sensor and the pressure sensor.

[0052] The installation cavity 102 is provided with an adjustment structure for adjusting the oscillation frequency according to the real-time data provided by the monitoring structure. The adjustment structure includes a push plate 3, a screw rod 4 is fixedly connected to one side of the push plate 3, and the screw rod 4 sequentially penetrates the installation cavity 102 and the adjustment cavity 104 away from the side of the push plate 3 and extends to the outside of the adjustment cavity 104. The part of the screw rod 4 located in the installation cavity 102 is provided with a spring, one end of the spring is fixedly connected to the push plate 3, and the other end of the spring is fixedly connected to the inner top wall of the installation cavity 102. The part of the screw rod 4 located in the adjustment cavity 104 is provided with a collar 5 (the structure of the collar 5 in this embodiment is similar to the expansion tube structure), and the outer thread of the collar 5 is matched with a moving part 6, and the outer wall of the moving part 6 is a worm structure. The moving part 6 is matched with an adjustment power part, and the adjustment power part includes a motor 7, which is fixedly connected to the inner wall of the adjustment cavity 104, and the output shaft of the motor 7 is coaxially fixedly connected with a worm wheel 8, and the worm wheel 8 is meshed with the moving part 6. The part of the screw rod 4 located in the outer part of the adjustment cavity 104 is threaded with a feedback structure, and the feedback structure is rotationally matched with the outer wall of the adjustment cavity 104. The feedback structure includes a ring 9. The screw 4 and the ring 9 form a ball screw structure. The ring 9 is a hollow structure. A speed sensor, a light component, a voice component and a speaker are installed inside the ring 9. The light component, the voice component and the speaker are all connected to the controller signal. The controller starts the corresponding component according to the feedback method of the feedback structure selected by the patient. At the same time, the controller adjusts the power of the light component, the voice component and the speaker according to the real-time data of the monitoring structure and the speed sensor.

[0053] The controller is connected with the monitoring structure, the regulating power part and the feedback structure signal. The controller collects and analyzes the real-time monitoring data of the monitoring structure. The controller adjusts the power of the regulating power part according to the real-time monitoring data of the monitoring structure. At the same time, the controller controls the feedback structure to give different forms of feedback according to the movement of the screw 4, and the controller can correct the power of the regulating power part according to the feedback result of the feedback structure.

[0054] The specific implementation process is as follows: before use, select a suitable mouthpiece 202 according to the size of the patient's mouth and install it on the mounting ring 2 at the breathing hole of the mask 201 to ensure good sealing. When in use, use the fixing component to wear the mask 201 on the patient's face, and adjust the tightness through the fixing component to ensure that the mask 201 fits the patient's face tightly.

[0055] The patient holds the mouthpiece 202 and begins to exhale. The airflow enters the air inlet cavity 101 through the mouthpiece 202, and triggers the airflow sensor and pressure sensor in the monitoring structure at the same time. The airflow sensor monitors the exhalation airflow velocity, and the pressure sensor measures the change in airway resistance. These data are transmitted to the controller in real time to provide a basis for subsequent adjustments.

[0056] As the airflow enters the air inlet chamber 101, the air pressure in the air inlet chamber 101 gradually rises, and the rising air pressure pushes the push plate 3 to move upward. The push plate 3 drives the screw 4 to rise in the mounting chamber 102, and compresses the spring at the same time. After the push plate 3 moves upward, the airflow in the air inlet chamber 101 enters the air outlet chamber 103, and the airflow in the air outlet chamber 103 flows to the outside from the air outlet hole 105. The air pressure in the air inlet chamber 101 is gradually reduced until the air pressure of the air inlet chamber 101 and the air outlet chamber 103 is balanced, and the push plate 3 descends under the action of the spring reset force to form a reciprocating motion. The reciprocating motion of the push plate 3 causes the airflow to oscillate in the device, and this oscillating airflow can reduce the viscoelasticity of mucus, making it easier to cough out or expel. The frequency of the oscillation usually simulates the frequency of the cilia beating, which helps to further promote the clearance of secretions in the airway. The optimal oscillation frequency and flow rate can be determined by the frequency and flow rate of the resonance / vibration of the lower chest and upper abdomen airways, and can be optimized by adjusting the angle of the device or using different settings.

[0057] The controller collects and analyzes monitoring data, and automatically adjusts the power of the regulating power member according to the preset usage parameters and real-time monitoring data, thereby changing the oscillation frequency. That is, the operation instruction is sent to the motor 7, the motor 7 rotates to drive the worm gear 8 to rotate, the worm gear 8 drives the moving member 6, and the moving member 6 rotates and rises or falls on the outer wall of the collar 5. As the position of the moving member 6 changes when it rotates, the tightening force of the collar 5 on the screw 4 will also change accordingly. When the moving member 6 rises, the tighter the tightening force of the collar 5 on the screw 4, the greater the upward resistance of the screw 4, resulting in a slower rise of the push plate 3, thereby reducing the oscillation frequency. On the contrary, when the moving member 6 descends, the tightening force of the collar 5 on the screw 4 will be loose, the upward resistance of the screw 4 will be reduced, the rise speed of the push plate 3 will be accelerated, and the oscillation frequency will also increase accordingly. The controller uses a sophisticated algorithm to dynamically adjust the speed and direction of the motor 7 according to the real-time data provided by the airflow sensor and the pressure sensor, thereby accurately controlling the rotation speed and direction of the moving member 6 and achieving fine-tuning of the tightening force of the collar 5. This fine-tuning mechanism ensures that the oscillation frequency can quickly respond to slight changes in the patient's exhalation process, maintaining optimal use results.

[0058] At the same time, the controller also has an intelligent learning function that can record and analyze the monitoring data and usage effects during each use, and continuously optimize the adjustment strategy. Over time, the controller can more accurately predict the patient's needs and automatically adjust to the oscillation frequency that best suits the patient.

[0059] When the push plate 3 moves upward, the screw 4 moves upward accordingly. Because the screw 4 and the ring 9 form a ball screw structure, the ring 9 will rotate as the screw 4 moves upward, and the rotation speed is proportional to the speed of the screw 4 moving upward. When the ring 9 rotates, the controller will send a preset response instruction to the light component, the voice component and the speaker according to the real-time monitoring data of the speed sensor of the ring 9. After receiving the instruction, the light component will provide intuitive visual feedback to the patient by changing the color, brightness or flashing mode of the light according to different oscillation frequencies and breathing patterns. This dynamically changing lighting effect not only adds to the fun of use, but also helps patients relax to a certain extent and reduces the tension during use. At the same time, the voice component and the speaker will also play preset music, sound effects or voice prompts according to the instructions. These sound feedbacks will also vary according to the oscillation frequency and breathing pattern. Some may be gentle melodies, while others may be encouraging voice prompts, aiming to create a more comfortable and pleasant use environment for patients and enhance their sense of participation and enthusiasm for use. The combined effects of lighting components, voice components and speakers not only enrich the feedback form of the device and increase the fun and interactivity of use, but also help patients better integrate into the use process through dual stimulation of vision and hearing, thereby improving the use effect and patient satisfaction.

[0061] As attached Figure 5 and attached Figure 6 As shown, the difference from Example 1 is that an anti-pressure sore component is installed on the side of the mask 201 close to the patient's skin, and the anti-pressure sore component includes an outer ring 10, which is fixedly connected to the mask 201, and a first groove 11 and a second groove 12 are opened on the side of the outer ring 10 close to the patient's skin, and a first air bag 13 and a second air bag 14 are respectively installed in the first groove 11 and the second groove 12, and the first air bag 13 and the second air bag 14 are both fixedly connected with a temperature sensor, and the first air bag 13 and the second air bag 14 are both provided with an air inlet and an air outlet, and the inlets are connected with a power part. In this embodiment, the power part is an air pump, and a one-way valve is installed on the air inlet and the air outlet, and the temperature sensor, the power part and the one-way valve are all connected with the controller signal, and the controller performs the command operation of opening and closing the power part and the one-way valve according to the monitoring data of the temperature sensor.

[0062] In this embodiment, the fixing component includes an elastic band 15, and through holes 18 are provided on both sides of the outer ring 10. The two ends of the elastic band 15 pass through the through holes 18 on both sides of the outer ring 10 respectively, wherein one end of the elastic band 15 is fixedly connected to the outer ring 10, and the same side of the other end of the elastic band 15 is fixedly connected with a sub-velcro 16 and a mother-velcro 17.

[0063] The specific implementation process is as follows: when in use, after the mask 201 is fitted to the patient's face, the elastic band 15 is passed through the through hole 18 and fixed by the sub-velcro 16 and the mother Velcro 17. The patient or medical staff can adjust the length of the elastic band 15 as needed to ensure that the mask 201 body is neither too tight to cause discomfort nor too loose to affect the use effect. After the mask 201 is worn, the one-way valve at the air inlet of the first air bag 13 is opened by the controller, and the controller sends an instruction to the air pump at the same time. The air pump inflates the first air bag 13, so that the first air bag 13 expands and fits the patient's face, which increases the sealing of the mask 201 body to a certain extent. After the inflation is completed, the one-way valve and the air pump are closed. After the first air bag 13 is inflated, the temperature sensor on the first air bag 13 monitors the temperature of the skin close to the first air bag 13 in real time, and transmits the monitoring data to the controller. When the real-time monitoring data (the skin temperature rises due to ischemia, or the skin becomes dry and warms due to long-term wearing) is greater than the first threshold of the temperature in the controller, the controller sends a command to another air pump, and the air pump inflates the second airbag 14, while controlling the opening of the one-way valve at the outlet of the first airbag 13. The first airbag 13 and the second airbag 14 can be inflated alternately, further making the main body of the mask 201 fit the patient's face, improving the sealing of the mask 201. At the same time, this alternating working mode can effectively prevent pressure sores caused by wearing the mask 201 for a long time. In addition, the inflation of the airbag can also be adaptively adjusted according to the patient's facial shape to provide a more personalized wearing experience.

[0064] Embodiment 3:

[0065] The difference from Example 2 is that it also includes an interaction module, which is used to preset parameters and view monitoring data in real time. The interaction module is connected to the controller signal, and the interaction module presets the parameters of the adjustment power parts and the adjustment parameters through the controller.

[0066] The specific implementation process is as follows: Through the interactive module, patients or medical staff can preset parameters such as oscillation frequency, time, and airflow speed range according to the patient's specific situation and usage needs. These parameters will directly affect the effect and comfort of use. At the same time, patients can also choose feedback methods such as light, voice or music, as well as the specific forms of these feedback methods (such as light color, music type, etc.). These settings will help patients get a better experience and effect during use. At the same time, during use, the interactive module displays monitoring data in real time, including expiratory airflow velocity, airway resistance and oscillation frequency, so that patients or medical staff can understand the usage at any time.

[0067] The interactive module records the monitoring data, usage parameters, patient feedback and other information during use, and can be exported or uploaded to the medical system for subsequent analysis and reference. With the addition of the interactive module, patients and medical staff can more conveniently preset usage parameters, view monitoring data in real time, and make adjustments as needed. This not only improves the flexibility and personalization of use, but also enhances the patient's sense of participation and satisfaction.

[0068] Embodiment 4:

[0069] The difference from Example 3 is that it also includes a remote monitoring module, which is used to remotely monitor the working status of the device and the patient's usage. The remote monitoring module is connected to the controller signal, and the remote monitoring module inputs the monitoring signal through the controller and issues corresponding control instructions.

[0070] The specific implementation process is as follows: The remote monitoring module receives signals from the controller in real time and monitors the working status of the device, including key parameters such as oscillation frequency, airflow velocity, and airway resistance. Through the built-in sensors of the device or additional equipment worn by the patient (such as heart rate monitors, blood oxygen saturation monitors, etc.), the remote monitoring module can also monitor the patient's physiological indicators and usage to ensure the safety and effectiveness of the use process. Medical personnel or authorized users can remotely adjust the use parameters, feedback methods, etc. through the remote monitoring platform to adapt to the different needs and changes in the patient's condition.

[0071] With the addition of the remote monitoring module, the oscillating expiratory positive pressure device of airway clearance technology not only realizes real-time monitoring and remote management of patient use, but also improves the efficiency and quality of medical services. Medical staff can check the patient's use anytime and anywhere, adjust the treatment plan in time, and ensure that the patient gets the best use effect. At the same time, the remote monitoring module also provides data analysis and report generation functions, which provides strong support for medical research and decision-making.

[0072] Embodiment 5:

[0073] The difference from Example 4 is that it also includes an early warning module, which is connected to the controller, the feedback structure and the remote monitoring module signal. When the monitoring structure detects abnormal data, the early warning module is activated by the controller to sound an alarm to remind the user to take corresponding measures. The ways in which the early warning module sends out an alarm include but are not limited to sound alarms, visual alarms, tactile alarms and remote notifications.

[0074] The specific implementation process is as follows: The monitoring structure collects key data such as the patient's expiratory airflow velocity, airway resistance, etc. in real time and transmits it to the controller. The controller analyzes the received data and compares it with the preset monitoring threshold to determine whether there is an abnormality. When abnormal data is detected (such as too low airflow velocity, too high airway resistance, or abnormal patient physiological indicators, etc.), the controller starts the early warning module according to the preset early warning conditions. The early warning module immediately alerts the patient or surrounding personnel through sound alarms (such as beeps), visual alarms (such as flashing lights), or tactile alarms (such as vibrations). At the same time, the early warning module will also send notifications to the remote monitoring platform so that medical personnel can remotely understand and handle abnormal situations.

[0075] By integrating the early warning module, the oscillating expiratory positive pressure device of airway clearing technology not only ensures the effectiveness of use, but also improves the ability to protect patient safety. Once an abnormal situation is detected, the system will immediately issue an alarm and notify relevant personnel to take countermeasures, thereby effectively avoiding potential risks and protecting the patient's life safety.

[0076] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
