Description

Technical Field

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

[0002] In the medical field, airway clearance refers to the removal of secretions and foreign matter from the respiratory tract through a series of measures to maintain airway patency and normal gas exchange. This process is crucial for maintaining respiratory health, especially in patients with chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, and lung infections. Airway clearance is primarily 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 beat rhythmically, pushing secretions and foreign matter adhering to the airway walls toward the throat, where they are then expelled from the body through coughing or swallowing. This is a crucial component of the natural airway clearance mechanism. However, in disease states, ciliary function may be impaired, increasing secretion retention, leading to airway obstruction and an 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 oscillatory expiratory positive pressure have gradually attracted attention. These devices simulate the cilia oscillation in the airways during natural breathing, generating periodic oscillatory airflow, thereby helping to reduce the viscoelasticity of airway secretions, promoting the movement of secretions into the larger airways and ultimately excretion from the body. However, most existing oscillatory expiratory positive pressure devices use a fixed-frequency oscillation mode and cannot dynamically adjust according to the patient's actual exhalation process and airway status, resulting in limited treatment effectiveness and possible discomfort to the patient due to frequency mismatch.

[0005] Furthermore, fixed-frequency oscillation patterns ignore patient variability across treatment stages or disease progression. For example, as treatment progresses, a patient's airway condition may improve or worsen, and a fixed oscillation frequency cannot flexibly adapt to these changes, limiting the maximum therapeutic effect. Furthermore, respiratory physiological characteristics, such as expiratory flow and expiratory time, vary between patients, placing higher demands on the adaptability of the oscillation frequency.

[0006] Given these challenges, the medical field urgently needs an oscillating expiratory positive pressure device that can monitor a patient's exhalation process in real time and automatically adjust the oscillation frequency to provide airway clearance. Such a device could better adapt to individual patient differences and changes in their condition, improving treatment efficacy and patient comfort while also reducing treatment risks. 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. By monitoring the patient's exhalation process in real time and automatically adjusting the oscillation frequency according to the monitoring data, it ensures that the oscillating airflow always matches the patient's exhalation process, thereby improving the treatment effect and patient comfort.

[0008] To achieve the above objectives, the present invention provides the following technical solutions: an oscillating expiratory positive pressure device for airway clearing technology, comprising a housing and a controller, wherein an air inlet cavity, a mounting cavity, and an air outlet cavity are sequentially disposed within the housing, an adjustment cavity is disposed on a top wall outside the mounting cavity, and two sides of the mounting cavity are connected to the air inlet cavity and the air outlet cavity, respectively. One side of the air inlet cavity is connected to an exhalation structure, a monitoring structure for real-time monitoring of the exhalation process is mounted in the exhalation structure, and an adjustment structure for adjusting the oscillation frequency based on real-time data provided by the monitoring structure is mounted in the mounting cavity. A plurality of air outlet holes are formed on a 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 portion of the screw located in the installation cavity is sleeved with a spring, 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 portion of the screw located in the adjusting cavity, a moving part is outer-circuited on 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, the threaded portion of the screw located on the outer side of the adjusting cavity is matched with a feedback structure, and the feedback structure is rotatably matched with the outer wall of the adjusting cavity;

[0010] The controller is connected to 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 types of feedback according to the movement of the screw, and the controller can correct the power of the regulating power part according to the feedback results of the feedback structure.

[0011] The technical principle of this solution is as follows: The patient exhales through the exhalation mechanism, and the monitoring mechanism monitors key parameters during exhalation in real time. As the patient exhales, air enters the inlet chamber and pushes the push plate upward. This upward movement connects the inlet and outlet chambers, allowing air to enter the outlet chamber and exit through the outlet holes. When the air pressure in the inlet and outlet chambers reaches equilibrium, the push plate descends under the spring's return force, completing one cycle. The reciprocating motion of the push plate generates oscillating airflow within the device, simulating the beating of cilia and promoting the clearance of secretions from the airways. Based on the real-time data provided by the monitoring mechanism, the controller uses an algorithm to analyze and automatically adjust the regulating element. The rotation of the regulating element drives the moving element to rotate upward or downward, thereby applying varying degrees of tightening force to the screw through the collar, affecting the push plate's upward speed and oscillation frequency. The feedback mechanism cooperates with the screw's rotation to provide different forms of feedback (such as sound and light) based on the screw's movement (i.e., changes in 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 clearance of secretions, and improving the treatment effect.

[0014] 2. This solution's automatic adjustment mechanism avoids the discomfort associated with fixed frequencies in traditional devices. By dynamically adjusting the oscillation frequency, the device can better adapt to individual patient differences and subtle changes during exhalation, improving patient comfort.

[0015] 3. The introduction of monitoring and feedback mechanisms in this solution enables the device to promptly detect and address abnormalities (such as abnormal airflow velocity and excessive airway resistance). By issuing alarms and automatically adjusting the oscillation frequency, the device effectively reduces risks during treatment and ensures patient safety. The feedback mechanism provides intuitive feedback based on the movement of the screw, helping patients understand the treatment progress and enhancing their sense of participation and comfort during treatment.

[0016] 4. As the core component of the entire device, the controller in this solution enables centralized control and management of monitoring data, regulating power components, and feedback mechanisms. This intelligent management approach not only improves the device's automation and operating efficiency, 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 lighting component, a voice component and a speaker are installed inside the ring. The lighting 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 lighting 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, 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. 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 the patient's confidence and compliance with the 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 in 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 respiratory status. These data provide an accurate basis for adjusting the power components, making the adjustment of the oscillation frequency more precise 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 components or other safety measures. This immediate 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] Benefits: The mouthpiece's detachable design allows for precise selection based on the patient's mouth size. This personalized fit not only ensures a secure fit, enhancing the seal and effectiveness of treatment, but also increases patient comfort and reduces treatment interruptions or resistance due to discomfort. The detachable mouthpiece design allows for easy cleaning and replacement, effectively reducing the risk of cross-infection. After each patient's use, the mouthpiece can be easily removed for thorough cleaning and disinfection, ensuring safe use for 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 the air inlet and the air outlet are both installed with a one-way valve, 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: By alternating the inflation of the first and second airbags, the anti-pressure sore component effectively disperses the pressure exerted by the mask on the skin, preventing the risk of poor circulation and pressure sores caused by prolonged single-point pressure. This dynamic pressure distribution mechanism significantly improves patient comfort and safeguards skin health during treatment. Simultaneously, the inflation of the airbags allows the mask to fit more closely to the patient's face, effectively reducing air leaks and improving the seal and effectiveness 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 to the child Velcro and the mother Velcro.

[0027] Beneficial effects: Through the combination of the sub-velcro and the main 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 is neither 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 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 fixation 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 engaged with the moving part.

[0029] Beneficial effects: By adjusting the speed and direction of the motor, flexible adjustment of the adjustment component can be achieved. 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 component. 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 adjustment parameters through the controller.

[0031] Beneficial Effects: The interactive module provides users with an intuitive, easy-to-use interface, allowing patients or medical staff to easily preset and adjust the parameters of the power components. This user-friendly design reduces operational difficulty, improves the system's usability, and makes it easy for more people to get started. By presetting parameters in the interactive module, users can customize the system based on the patient's specific situation and needs. For example, the airbag inflation volume and pressure can be adjusted according to the patient's facial contour and comfort requirements; the ventilator parameters can be adjusted according to the patient's breathing habits and treatment effects. This personalized customization function improves the targeted and effective 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, and the remote monitoring module inputs the monitoring signal through the controller and issues corresponding control instructions.

[0033] Beneficial Effects: The remote monitoring module provides real-time data on the device's operating status and patient usage, such as mask seal, airbag pressure, and respiratory rate. This data is crucial for remote medical support and timely intervention, ensuring a swift response when patients need help. The remote monitoring module also enables medical staff to monitor and provide guidance on patient usage 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 issue an alarm, reminding the user to take corresponding measures. The ways in which the early warning module issues an alarm include but are not limited to sound alarms, visual alarms, tactile alarms and remote notifications.

[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 an alarm can be issued. This immediate 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 play a role; for telemedicine scenarios, remote notifications become an indispensable means of communication.

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

[0049] Example 1:

[0050] As attached Figures 1 to 7 As shown: an oscillating expiratory positive pressure device with airway clearing technology, including a shell 1 and a controller, wherein an air inlet cavity 101, a mounting cavity 102 and an air outlet cavity 103 are sequentially arranged inside the shell 1, and a plurality of air outlet holes 105 are opened on the side wall of the air outlet cavity 103. An adjustment cavity 104 is provided on the outer top wall of the mounting cavity 102. Both sides of the mounting cavity 102 are connected to the air inlet cavity 101 and the air outlet cavity 103 respectively. One side of the air inlet cavity 101 is connected to an exhalation structure, and a monitoring structure for real-time monitoring of the exhalation process is installed in the exhalation structure. The exhalation structure includes a mask 201, and a breathing hole is opened on the mask 201. A mounting ring 2 is fixedly connected to the breathing hole. 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 to the air inlet cavity 101. The mouthpiece 202 is connected to the air inlet cavity 101 through the mounting ring 2. 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 in 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 mounting chamber 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 4 is fixedly connected to one side of the push plate 3, and the screw 4 is away from the push plate 3 and sequentially passes through the mounting chamber 102 and the adjustment chamber 104 and extends to the outside of the adjustment chamber 104. The portion of the screw 4 located in the mounting chamber 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 mounting chamber 102. The portion of the screw 4 located in the adjustment chamber 104 is provided with a collar 5 (the structure of the collar 5 in this embodiment is similar to the expansion tube structure), the outer thread of the collar 5 is matched with a moving part 6, the outer wall of the moving part 6 is a worm structure, and the moving part 6 is matched with an adjustment power part, which includes a motor 7, which is fixedly connected to the inner wall of the adjustment chamber 104, and the output shaft of the motor 7 is coaxially fixedly connected with a worm gear 8, which meshes with the moving part 6. The screw 4 is located in the outer part of the adjustment chamber 104 and is threaded with a feedback structure, which rotates with the outer wall of the adjustment chamber 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 lighting component, a voice component and a speaker are installed inside the ring 9. The lighting 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 lighting 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 to 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 types 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 results of the feedback structure.

[0054] The specific implementation process is as follows: Before use, select the appropriate mouthpiece 202 based on the patient's mouth size and install it on the mounting ring 2 at the breathing hole of the mask 201 to ensure a good seal. During use, the mask 201 is placed on the patient's face using the fixing assembly, and the tightness is adjusted by the fixing assembly to ensure that the mask 201 fits the patient's face tightly.

[0055] The patient places mouthpiece 202 in their mouth and begins to exhale. Airflow passes through mouthpiece 202 and enters air inlet chamber 101, triggering the airflow sensor and pressure sensor in the monitoring mechanism. The airflow sensor measures the expiratory airflow velocity, while the pressure sensor measures changes in airway resistance. This data is transmitted to the controller in real time, providing a basis for subsequent adjustments.

[0056] As air enters the inlet chamber 101, the air pressure therein gradually rises, pushing the push plate 3 upward. This upward movement of the push plate 3 drives the screw 4 upward within the mounting chamber 102, compressing the spring. The upward movement of the push plate 3 allows the air in the inlet chamber 101 to enter the outlet chamber 103, where it then flows out through the outlet hole 105. This gradually reduces the air pressure in the inlet chamber 101 until the pressures in the inlet and outlet chambers 101 and 103 reach equilibrium. The push plate 3 then descends under the spring's return force, creating a reciprocating motion. The reciprocating motion of the push plate 3 causes the airflow to oscillate within the device. This oscillating airflow can reduce the viscoelasticity of mucus, making it easier to cough or expel. The oscillation frequency typically mimics the frequency of ciliary beats, which further promotes the clearance of secretions from the airway. The optimal oscillation frequency and flow rate can be determined by the resonance / vibration frequency and flow rate of the lower chest and upper abdominal airways and can be optimized by adjusting the device's angle or using different settings.

[0057] The controller collects and analyzes monitoring data and automatically adjusts the power of the regulating element based on preset operating parameters and real-time monitoring data, thereby changing the oscillation frequency. Specifically, it sends operating instructions to motor 7, which rotates worm gear 8, which in turn drives moving element 6. Moving element 6 then rotates and rises or falls on the outer wall of collar 5. As the position of moving element 6 changes during rotation, the tightening force of collar 5 on screw 4 also changes. As moving element 6 rises, the tightening force of collar 5 on screw 4 increases, increasing the upward resistance of screw 4, slowing the rise of push plate 3 and thereby reducing the oscillation frequency. Conversely, as moving element 6 descends, the tightening force of collar 5 on screw 4 decreases, reducing the upward resistance of screw 4 and accelerating the rise of push plate 3, thereby increasing the oscillation frequency. Using a sophisticated algorithm, the controller dynamically adjusts the speed and direction of motor 7 based on real-time data from airflow and pressure sensors, thereby precisely controlling the rotational speed and direction of moving element 6 and fine-tuning the tightening force of 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] The controller also features intelligent learning capabilities, recording and analyzing monitoring data and user experiences during each use, continuously optimizing its adjustment strategy. Over time, the controller can more accurately predict the patient's needs and automatically adjust to the oscillation frequency that best suits them.

[0059] As the push plate 3 moves upward, the screw 4 also moves upward. Because the screw 4 and the ring 9 form a ball screw structure, the ring 9 rotates as the screw 4 moves upward, and its rotation speed is proportional to the speed of the screw 4's upward movement. As the ring 9 rotates, the controller sends preset response instructions to the lighting component, voice component, and speaker based on real-time monitoring data from the ring 9's speed sensor. Upon receiving the instructions, the lighting component changes the color, brightness, or flashing pattern of the light according to the oscillation frequency and breathing pattern, providing intuitive visual feedback to the patient. This dynamically changing lighting effect not only adds to the fun of use but also helps patients relax and reduce tension during use. Simultaneously, the voice component and speaker play preset music, sound effects, or voice prompts according to the instructions. This audio feedback also varies depending on the oscillation frequency and breathing pattern, ranging from gentle melodies to encouraging voice prompts, aiming to create a more comfortable and enjoyable user environment for patients, enhancing their sense of engagement and motivation. 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 the dual stimulation of vision and hearing, thereby improving the use effect and patient satisfaction.

[0060] Example 2:

[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 provided on the side of the outer ring 10 close to the patient's skin. The first airbag 13 and the second airbag 14 are respectively installed in the first groove 11 and the second groove 12, and the first airbag 13 and the second airbag 14 are fixedly connected to a temperature sensor. The first airbag 13 and the second airbag 14 are both provided with an air inlet and an air outlet, and the inlets are connected to a power part. In this embodiment, the power part is an air pump, and the air inlet and the air outlet are both installed with a one-way valve. The temperature sensor, the power part and the one-way valve are all connected to the controller signal, and the controller performs the opening and closing instructions on 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 child Velcro 16 and a mother Velcro 17.

[0063] The specific implementation process is as follows: when in use, after fitting the mask 201 to the patient's face, pass the elastic band 15 through the through hole 18 and fix it with the sub-velcro 16 and the main 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 airbag 13 is opened by the controller, and at the same time the controller sends an instruction to the air pump, and the air pump inflates the first airbag 13, so that the first airbag 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 airbag 13 is inflated, the temperature sensor on the first airbag 13 monitors the temperature of the skin close to the first airbag 13 in real time and transmits the monitoring data to the controller. When real-time monitoring data (skin temperature increases due to ischemia, or dryness and temperature rise due to prolonged wear) exceeds the first temperature threshold in the controller, the controller issues a command to another air pump, which inflates the second airbag 14 and simultaneously controls 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 alternately inflated, further allowing the main body of the mask 201 to fit the patient's face and improving the sealing performance of the mask 201. At the same time, this alternating operation can effectively prevent pressure sores caused by wearing the mask 201 for a long time. In addition, the inflation of the airbags can be adaptively adjusted according to the patient's facial shape, providing a more personalized wearing experience.

[0064] Example 3:

[0065] The difference from Example 2 is that 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 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 speed, airway resistance and oscillation frequency, so that patients or medical staff can understand the usage at any time.

[0067] The interactive module records monitoring data, usage parameters, patient feedback, and other information during use, and can export or upload it to medical systems 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 increases flexibility and personalization, but also enhances patient engagement and satisfaction.

[0068] Example 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 real-time signals from the controller and monitors the device's operating status, including key parameters such as oscillation frequency, airflow velocity, and airway resistance. Through the device's built-in sensors or additional equipment worn by the patient (such as a heart rate monitor and blood oxygen saturation monitor), the remote monitoring module can also monitor the patient's physiological indicators and usage status to ensure safety and effectiveness during use. Medical personnel or authorized users can remotely adjust usage parameters and feedback methods through the remote monitoring platform to adapt to the patient's different needs and changes in condition.

[0071] With the addition of a remote monitoring module, the oscillating expiratory positive pressure device with airway clearance technology not only enables real-time monitoring and remote management of patient use, but also improves the efficiency and quality of medical services. Medical staff can monitor patient usage anytime, anywhere, and adjust treatment plans promptly to ensure optimal patient outcomes. The remote monitoring module also provides data analysis and report generation capabilities, providing strong support for medical research and decision-making.

[0072] Example 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 issue an alarm, reminding the user to take corresponding measures. The ways in which the early warning module issues 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, compares it with the preset monitoring threshold, and determines whether there is any abnormality. When abnormal data is detected (such as too low airflow velocity, too high airway resistance, or abnormal patient physiological indicators), the controller activates the early warning module according to the preset early warning conditions. The early warning module immediately issues an alarm to 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 a notification to the remote monitoring platform so that medical personnel can remotely understand and handle abnormal situations.

[0075] By integrating a warning module, the oscillating expiratory positive pressure device with airway clearance technology not only ensures effective use but also enhances patient safety. If an abnormality is detected, the system will immediately issue an alarm and notify relevant personnel to take appropriate measures, effectively avoiding potential risks and protecting patients' lives.

[0076] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
