Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a device for promoting sputum discharge, and in particular to a percussion system for airway clearing. Background Art

[0002] Airway clearance is a key part of respiratory disease management, especially for patients with chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), bronchiectasis, pneumonia, etc. Effective airway clearance can loosen and discharge mucus, reduce airway obstruction, improve lung function, prevent infection, and improve quality of life.

[0003] Chest percussion and vibration techniques are important therapeutic methods for loosening and clearing sputum in the lungs. For example, the study by Chu Xu, Zhang Yan, Geng An, etc. in "Analysis of the Effect of Using Airway Clearance System in Patients with Stroke and Pneumonia" (see Changzhou Practical Medicine, 2024, (Issue 1)) found that both chest percussion vibration expectoration intervention and airway clearance system expectoration intervention can effectively promote patient expectoration and reduce sputum retention. Existing vibrating expectoration equipment generates high-frequency vibration (generally 5-25Hz) through compressed air or other power sources, which is transmitted to the patient's chest through a special inflatable vest, chest strap or handheld vibrator. Percussion or patting is a rhythmic tapping or patting of the patient's chest by mechanical means or manually, usually at a frequency of 60 to 180 times per minute. Although there are many types of vibrating expectoration equipment or percussion devices, the existing instruments and equipment provide single and fixed functions, and do not consider the differences in the patient's body to perform percussion or vibration expectoration, so the effect is not good. For example, CN113304008A discloses a vibrating percussion expectoration machine percussion device, which adjusts the amplitude of the percussion device by changing the relative position of the adjustment sleeve and the eccentric shaft, so that the expectoration machine can adjust the amplitude without replacing the percussion device, thereby adapting to patients of different ages and physical conditions, but the technical solution cannot perform percussion according to the patient's lesion site, that is, the functional mode is single and not targeted. For example, CN220442892U discloses a chest belt type vibrating expectoration device, which performs vibration percussion by arranging the expectoration components on the inner surface of the belt body corresponding to the parts that fit the human body (such as the left upper lobe, the left lingual lobe, the left lower lobe, the right upper lobe, the right middle lobe, and the right lower lobe), although it can theoretically vibrate or tap the patient's lesion site, but due to individual differences in patients, it may not be possible to target the lesion site when actually tapping or vibrating, and the technical solution does not disclose the vibration, tapping or tapping sequence, vibration, tapping or tapping strength, etc., so it cannot achieve a better effect.

[0004] In some cases, patients expectorate by high-frequency vibration, which causes high-frequency vibration and shear force on the mucus layer in the airway, destroying the adhesion between the mucus and the airway wall, causing it to fall off the airway wall and enter the larger airway. The loosened mucus can be easily coughed out or excreted from the body through ciliary movement with the help of gravity and coughing. In other cases, patients expectorate by tapping or patting, and the local pressure changes caused by tapping or patting can cause a brief displacement of the mucus layer in the airway, loosening the mucus attached to the airway wall. However, current instruments and equipment cannot adjust the working mode according to the patient's actual condition, and cannot provide personalized airway clearance solutions to improve the treatment effect. Therefore, the expectoration instruments provided by the prior art are still lacking in improving the patient's respiratory function and quality of life.

[0005] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0006] Due to the different conditions of the patients themselves, for patients with different distribution and properties of mucus in the lungs, the single function and fixed mode of the existing sputum removal instruments and equipment are difficult to achieve the best effect. The existing percussion devices usually use fixed vibration frequency, intensity and percussion force, and cannot be adjusted according to individual differences of patients. There are significant differences in the airway conditions, mucus characteristics, breathing patterns, etc. of different patients, and fixed parameter settings are difficult to meet the needs of all patients. For example, for patients with thinner mucus, too strong vibration may cause excessive stimulation to their airways; while for patients with thicker mucus, weaker vibrations cannot effectively loosen mucus. On the other hand, the existing percussion devices usually require patients, their families or medical staff to manually operate, select working modes, adjust parameters, etc., which increases the complexity of operation. At the same time, in the process of manual operation, the operator usually performs expectoration based on his own subjective feelings or experience, and manual operation is prone to misoperation during treatment, such as the grasp of percussion order and percussion force, which will reduce the treatment effect.

[0007] In view of the deficiencies of the prior art, the present invention provides a percussion system for airway clearance, the percussion system comprising a percussion device and a percussion garment, the percussion device comprising:

[0008] A first mechanical energy applying part, which achieves airway clearance by vibration;

[0009] A second mechanical energy applying part, which can selectively apply tapping or slapping to achieve further airway clearance;

[0010] The knocker cooperates with the knocking clothes to switch the working mode according to the feedback signal given by the knocking clothes, that is, the first mechanical energy applying part or the second mechanical energy applying part is selectively enabled, wherein when the second mechanical energy applying part is enabled, tapping or slapping is selectively applied.

[0011] Technical effect of the present technical solution: The present technical solution provides a first mechanical energy applying part that works in a vibration mode and a second mechanical energy applying part that works in a tapping or slapping mode. The first mechanical energy applying part loosens mucus and promotes its discharge through high-frequency vibration, and the vibration can act on the entire chest or a specific area. The second mechanical energy applying part selectively applies tapping or slapping, which loosens mucus through local mechanical impact force, especially in some airway areas that require targeted treatment. The high-frequency vibration generated by the first mechanical energy applying part causes the mucus layer to undergo high-frequency shear motion by generating rapid mechanical vibrations in the airway. This shear force can destroy the intermolecular forces (such as van der Waals forces, hydrogen bonds, etc.) between the mucus and the airway wall, thereby weakening the adhesion of the mucus. The shear force generated by the high-frequency vibration can cause a slight displacement of the contact interface between the mucus layer and the airway wall, causing the mucus layer to gradually separate from the airway wall. High-frequency vibration can also promote flow inside the mucus, reduce the friction between the mucus and the airway wall, and further weaken the adhesion. The local pressure change generated by the tapping or slapping of the second mechanical energy applying part can cause a brief displacement of the mucus layer in the airway, loosening the mucus attached to the airway wall; on the other hand, the shock wave generated by the tapping or slapping can penetrate the airway wall, causing the mucus to fall off the airway wall and enter the larger airway.

[0012] Furthermore, the tapper of the present invention cooperates with the tapping garment to automatically or manually switch the working mode of the tapper, ensuring that the tapper activates the corresponding mechanical energy applying part according to a specific working mode. Specifically, the working mode of the tapper can be switched according to the feedback signal given by the tapping garment, and the first mechanical energy applying part (vibration) or the second mechanical energy applying part (tapping or patting) is selectively activated. The design of the present invention enables the tapper to flexibly adjust the treatment method according to the specific conditions of the patient, for example, the mode of the tapper is selectively activated according to the patient's lesion location, lesion area, mucus accumulation, etc., to ensure the best airway clearance effect.

[0013] According to a preferred embodiment, the percussion garment is a garment body generated in combination with the patient's body geometry, and a target vibration area is added to the garment body according to a lung image of the corresponding patient, wherein the lung image is determined according to the patient's imaging results.

[0014] According to a preferred embodiment, the tapping clothing is equipped with a proximity sensor for determining whether the target vibration area is in contact with the tapper, a tapping sensor for collecting the vibration intensity and duration generated in the corresponding part when the target vibration area is in contact with the tapper, and a timer for collecting the duration of the tapper acting on the target vibration area.

[0015] According to a preferred embodiment, the tapping device that cooperates with the tapping garment is configured to determine its working mode according to the degree of infection of each infected area determined by the imaging results.

[0016] According to a preferred embodiment, the tapper further includes a central processor, and the central processor of the tapper selectively activates the first mechanical energy applying part or the second mechanical energy applying part according to the received feedback signal of the tapping clothing.

[0017] According to a preferred embodiment, the central processor of the tapper can control the working modes of the first mechanical energy applying part and the second mechanical energy applying part.

[0018] According to a preferred embodiment, the tapper also includes a communication interface capable of transmitting signals with the tapping clothing.

[0019] According to a preferred embodiment, the tapper is configured to: when the feedback signal of the tapping garment shows that the target vibration area is the upper lobe of the lungs, activate the first mechanical energy applying part to perform airway clearing on the target vibration area.

[0020] According to a preferred embodiment, the tapper is configured as follows: when the feedback signal of the tapping clothing shows that the target vibration area is the middle lobe of the lungs, the tapping working mode of the second mechanical energy applying part is first activated, and then the first mechanical energy applying part is activated to clear the airway of the target vibration area.

[0021] According to a preferred embodiment, the tapper is configured as follows: when the feedback signal of the tapping garment shows that the target vibration area is the lower lobe of the lungs, the tapping working mode of the second mechanical energy applying part is first activated, and then the first mechanical energy applying part is activated to clear the airway of the target vibration area.

[0022] Beneficial effects of the technical solution: The present invention provides a percussion device for airway clearance, which cooperates with the percussion clothing to achieve the purpose of intelligently switching the working mode according to the patient's lung image analysis results. According to the patient's lung image, the percussion device can select the appropriate percussion, patting or vibration mode according to the different infection levels of different lobes of the lung (such as the upper lobe, middle lobe, and lower lobe) on the percussion clothing, reducing the risk of stimulation in the prior art when family members or caregivers cannot find the exact position to perform expectoration operations.

[0023] On the other hand, the tapper can perform a predetermined tapping operation according to the tapping scheme generated by the tapping garment. The vibration components on the tapping garment are arranged in an array to ensure that multiple target vibration areas on the patient's chest and back can be covered. On this basis, the various working modes of the tapper are combined with each other to improve the effect of treatment. That is, the array-arranged vibration components and the local reinforcement of tapping / patting significantly improve the efficiency and effect of treatment. In addition, the data of each treatment can be recorded to achieve subsequent feedback adjustment. For example, the tapper can automatically adjust the force and frequency of tapping, patting or vibration according to the patient's treatment history and effect to ensure that each treatment can achieve the best effect. Existing tappers usually rely on the operator's experience and manual adjustment to determine the tapping position, which is prone to errors. The tapping garment of the present invention combines the patient's lung image analysis results, and the tapper matched with the tapping garment can accurately locate each target vibration area. This positioning method of the tapping garment made based on the patient's image results ensures the accuracy of the treatment and avoids the errors that may be caused by traditional manual operations. Especially for complex anatomical structures (such as the lower lobe airway), this precise positioning can significantly improve the effect of treatment. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the drawings disclosed in the following embodiments are all for the convenience of explaining the technical features of the present invention, rather than for limiting its practicable forms.

[0037] Example 1

[0038] This embodiment provides a percussion system for airway clearance, the percussion system comprising a percussion device 100 and a percussion garment 200. Figures 1 to 5 As shown. The tapper 100 includes a first mechanical energy applying part 110, which achieves airway clearance by vibration; and a second mechanical energy applying part 120, which can selectively apply tapping or slapping to achieve further airway clearance. The tapper 100 cooperates with the tapping garment 200, and switches the working mode according to the feedback signal given by the tapping garment 200. That is, the tapper 100 selectively enables the first mechanical energy applying part 110 or the second mechanical energy applying part 120, wherein when the second mechanical energy applying part 120 is enabled, tapping or slapping is selectively applied.

[0039] The tapper 100 is preferably integrated into a sputum removal machine, for example, a multi-frequency vibration sputum removal machine. The tapper 100 preferably also includes a central processing unit 130 (CPU), such as Figure 1 As shown. The central processor 130 of the tapper 100 receives a feedback signal from the tapping garment 200. The central processor 130 of the tapper 100 selectively enables the first mechanical energy applying part 110 or the second mechanical energy applying part 120 according to the received feedback signal of the tapping garment 200. The central processor 130 of the tapper 100 can control the working mode of the first mechanical energy applying part 110 and the second mechanical energy applying part 120. The tapper 100 is preferably also designed with a storage module 140 and a communication interface 150. The storage module 140 of the tapper 100 is used to store the patient's treatment history (parameters and effects of each treatment, etc.), image analysis results from the tapping garment 200, and personalized treatment plans. The tapper 100 and the tapping garment 200 are transmitted signals or data through a wired or wireless communication interface 150. The communication interface 150 can, for example, use technologies such as Bluetooth, Wi-Fi, NFC, etc. The tapper 100 can also be connected to the tapping garment 200 through a USB data cable. When the tapper 100 is connected to the tapping clothing 200 , the tapping scheme generated by the tapping clothing 200 is sent to the tapper 100 .

[0040] According to this embodiment, the percussion garment 200 is a garment body generated in combination with the patient's body geometry, and a target vibration area 210 determined according to the corresponding patient's lung image is added to the garment body, wherein the lung image is determined according to the patient's imaging results. Specifically, the percussion garment 200 is a garment body customized based on the patient's body geometry, which can fit the patient's chest and back tightly. The target vibration area 210 on the garment body determined according to the patient's lung imaging analysis results is divided based on the anatomical structure of the lung lobe, such as Figure 3 According to a preferred embodiment, the target vibration area 210 of this embodiment includes the right upper lobe, the right middle lobe, the right lower lobe, the left upper lobe and the left lower lobe, and the left upper lobe also includes a sub-segment called "lingula". The target vibration area 210 on the percussion clothing 200 is preferably marked by a special sensor or conductive fiber so that the percussion device 100 can identify and act on the target vibration area 210.

[0041] The shape of the tapping garment 200 is preferably similar to that of a vest or a short-sleeved shirt. According to a preferred embodiment, a special capacitive sensing area is sewn into the target vibration area 210 of the tapping garment 200. The capacitive sensing area is made of a material with a certain dielectric constant and is soft and comfortable, such as a high dielectric polymer composite material embedded in a thin sheet, to form a capacitive sensing mark 260, such as Figure 6As shown, its shape and size are arranged according to human anatomy and target vibration area 210, for example, circular or square sensing areas are set in the middle areas of different lobes, with an area of ​​about 1 to 10 square centimeters, so as to effectively contact with the tapping head of the tapping device 100 and produce obvious capacitance changes. The tapping head of the tapping device 100 is preferably provided with a high-precision capacitance detection circuit, and the core component is a microcontroller (MCU) and a capacitance-to-digital conversion chip (CDC) connected thereto. When the tapping head of the tapping device 100 approaches the capacitance sensing area of ​​the tapping clothing 200, the human body, the capacitance sensing area and the detection circuit in the tapping head of the tapping device form a capacitance coupling system. The CDC chip can convert the detected capacitance value change into a digital signal and transmit it to the MCU. The MCU pre-stores the operation instruction set corresponding to different capacitance value ranges. For example, the capacitance value is set to the gentle tapping mode in the interval [C1, C2], and the operation time is 10 seconds; the interval [C3, C4] corresponds to the moderate tapping mode, the duration is 15 seconds; the interval [C5, C6] is the strong tapping mode, the duration is 20 seconds, etc. According to the received capacitance digital signal, the MCU quickly determines the capacitance value interval to which it belongs through the internal algorithm, thereby determining the corresponding tapping mode and duration. After the MCU determines the operation mode and duration, the MCU sends a control signal to the actuator in the tapping head of the tapper 100. The actuator includes a small motor and an eccentric wheel or cam mechanism connected thereto, and realizes tapping actions of different intensities and durations by changing the speed and rotation time of the motor. For example, in the gentle tapping mode, the MCU controls the motor to run at a lower speed for 10 seconds, and a gentle tapping force is generated through the eccentric wheel; the moderate and strong tapping modes increase the motor speed and operation time accordingly to provide a stronger tapping effect. In this embodiment, the MCU of the tapping head of the tapping device 100 can be accurately calibrated to determine the reference range of capacitance values ​​under different human tissue characteristics, environmental temperature and humidity, and store these parameters in the MCU of the tapping head of the tapping device 100, so that operation control can be accurately performed according to the change of capacitance value during actual use. At the same time, a certain adjustable parameter interface is reserved to further optimize the corresponding relationship between capacitance value and operation mode and duration according to the specific feedback and treatment effect of the patient during clinical use, so as to improve the accuracy and effectiveness of treatment.

[0042] According to a preferred embodiment, the target vibration area 210 of the tapping garment 200 is provided with a mark made of a special temperature-sensitive color-changing material, namely, a temperature-sensitive color-changing mark 270, such as Figure 7As shown. The shape and color of the logo on the target vibration area 210 can be designed according to different body shapes or conditions. For example, the red circular area represents tapping (A operation), the yellow triangular area represents slapping (B operation), and the blue square area represents vibration (C operation). Before operation, the tapper 100 first scans the target vibration area 210 of the chest of the tapping clothing 200 with an infrared thermometer, and determines the operation mode by identifying the shape and color of the color-changing area. The characteristics of this temperature-sensitive color-changing material only take effect when the tapper 100 actively detects, and the tapping clothing 200 does not need to be powered by itself to feedback information. The tapping head of the tapper 100 is preferably integrated with an infrared temperature sensor, so that the color change of the temperature-sensitive color-changing material can be accurately identified. The target vibration area 210 in the chest area of ​​the tapping clothing 200 is divided into left and right sides according to human anatomy. The right side corresponds to the three lobes of the right lung (RUL, RML, RLL), and the left side corresponds to the two lobes and lingula (LUL, Lingula, LLL) of the left lung. When the patient puts on the percussion garment 200, the percussion device 100 will first scan the target vibration area 210 of the chest. For example, if a blue square mark is scanned in the right lower lobe, it indicates that the area needs to be vibrated (C operation); if a yellow triangle mark is scanned in the right middle lobe, it indicates that the area needs to be tapped (B operation). The examples are not listed here. According to a preferred embodiment, the target vibration area 210 of the percussion garment 200 is embedded with a small square containing magnetic material, such as Figure 8 As shown. The positions of the small squares containing magnetic materials are precisely arranged according to the anatomical structure of the lungs to ensure that each lobe or subsegment has a corresponding magnetic marker 280. For example, the right upper lobe is provided with a small square with an N pole outward; the right middle lobe is provided with two small squares with an S pole outward, arranged in a specific pattern (such as a vertical arrangement); the right lower lobe is provided with three small squares with an N pole outward, arranged in a triangle; the left upper lobe is provided with a small square with an N pole outward; the left lower lobe is provided with three small squares with an S pole outward, arranged in an inverted triangle; the tongue segment is provided with two small squares with an S pole outward, arranged in a horizontal arrangement.

[0043] The knocking head of the knocker 100 is preferably equipped with a magnetic sensor. When the knocking head of the knocker 100 is close to the target vibration area 210 of the knocking clothing 200, the magnetic sensor starts to work and detects changes in the surrounding magnetic field. The magnetic sensor transmits the detected magnetic field information to the central processor 130 of the knocker 100. The central processor 130 analyzes the direction, intensity and arrangement of the magnetic field through an algorithm to identify the current target vibration area 210 and its corresponding operation mode. If a small square with an N pole outward is detected, it is identified as the upper right lobe; if two small squares with S poles arranged vertically outward are detected, they are identified as the right middle lobe. According to the recognition result, the central processor 130 of the knocker 100 selects the corresponding operation mode (such as knocking, clapping or vibration) and drives the corresponding mechanical energy application part through the control unit.

[0044] The execution operation of the knocker 100 of this embodiment is, for example, as follows: Fig. 9 The truth table shown in the figure is used to ensure that each identification system (operation sequence, tap or vibration selection, time and intensity) can be accurately mapped to a specific device operation. According to this embodiment, "tap or vibration selection" means selecting the vibration mode of the first mechanical energy applying part 110 or selecting the tap / slap mode of the second mechanical energy applying part 120.

[0045] According to this embodiment, the tapping system has three identification systems: a first identification system for controlling the operation sequence, a second identification system for controlling the tapping or vibration selection, and a third identification system for controlling the time and intensity. The first identification system is an operation sequence identification system, in which "00" represents no operation and the device is on standby; "01" represents the operation sequence of left first and right second; "10" represents the operation sequence of right first and left second; "11" represents reserved for standby. The second identification system controls the tapping or vibration selection, in which "0" represents the vibration operation; "1" represents the tapping operation. The third identification system controls the time and intensity selection, in which "000" represents the shortest time and lowest intensity; "001" represents a short time and low intensity; "010" represents a medium time and medium intensity; "011" represents a long time and medium intensity; "100" represents a short time and high intensity; "101" represents a medium time and high intensity; "110" represents a long time and high intensity.

[0046] This embodiment is described by taking the cooperation of the magnetic sensor and the identification system as an example. The tapping head of the tapper 100 is equipped with a highly sensitive magnetic sensor, which can detect the changes of magnetic fields in different positions, directions and intensities, and convert them into binary coded signals. Use digital logic gate circuits (such as AND gates, OR gates, NOT gates, etc.) to decode the binary coded signals from the magnetic sensor to generate control signals. The central processor 130 of the tapping head controls the specific operation mode and parameters of the tapper according to the decoded signal. The patient puts on the tapping clothes 200 to ensure that the small squares of magnetic materials in all target vibration areas 210 are correctly fitted to the corresponding positions of the chest and back. The tapper 100 is turned on and enters the standby state, waiting for the next operation. When the tapper 100 approaches the target vibration area 210 of the tapping clothes 200, the magnetic sensor starts to work and detects the changes in the surrounding magnetic field. The magnetic sensor transmits the detected magnetic field information to the central processor 130 of the tapper 100, and the central processor 130 analyzes the direction, intensity and arrangement of the magnetic field through an algorithm to identify the current target vibration area and its corresponding operation mode. Assuming the detection results are "01", "1", "010", it means that the left chest is tapped for a medium time and a medium intensity. The central processor 130 controls the mechanical energy applying part of the tapper 100 according to this information to perform the tapping operation according to the set time and intensity. The tapper 100 can store the time, intensity, patient response and other data of each treatment for subsequent analysis and optimization of the treatment plan.

[0047] Example 2

[0048] This embodiment is a further improvement of Embodiment 1, and repeated contents will not be repeated here.

[0049] The tapping clothing 200 is equipped with a proximity sensor 230 for determining whether the target vibration area 210 is in contact with the tapper 100, a tapping sensor 240 for collecting the vibration intensity and duration generated in the corresponding part when the target vibration area 210 is in contact with the tapper 100, and a timer 250 for collecting the duration of the tapper 100 acting on the target vibration area 210.

[0050] According to a preferred embodiment, an LED light is embedded in the target vibration area 210. When the tapper 100 approaches the target vibration area 210, the LED light will light up to remind the operator or patient of the current working state of the tapper 100. The LED light is provided with different colors to indicate different working modes, such as blue for vibration, red for tapping, and green for slapping. Furthermore, a progress indicator light is installed on the clothing body to display the progress of the treatment in real time. For example, when the treatment of a certain target vibration area 210 is completed, the corresponding LED light will go out, and the corresponding LED light of the next target vibration area 210 to be treated will turn on, and the tapper 100 will continue to treat the next area.

[0051] Specifically, the proximity sensor 230 installed near the target vibration area 210 is used to determine whether the tapper 100 is in contact with the clothing body. When the tapper 100 is close to the target vibration area 210, the proximity sensor 230 will send a signal to determine that the tapper 100 starts working. At the same time, the proximity sensor 230 can monitor the contact state of the tapper 100 with the target vibration area 210 in real time to ensure the accuracy of each treatment, that is, to ensure that the tapper 100 is operated in the correct position to avoid misoperation or interference with non-target areas. The tapping sensor 240 installed in the target vibration area 210 is used to collect the vibration intensity and duration generated when the tapper 100 acts on the corresponding part. The timer 250 built into the tapping clothing 200 is used to collect the duration of the tapper 100 acting on the target vibration area 210. The timer 250 can record the duration of each treatment to ensure the accuracy and consistency of the treatment. According to the feedback of the tapping sensor 240, the control unit of the tapper 100 can dynamically adjust the strength of the tapping or slapping. The timer 250 can also help the tapper 100 to perform the predetermined tapping operation in time periods according to a predetermined tapping sequence.

[0052] According to the image analysis results, specific target vibration areas 210 are added to the clothing body of the percussion clothing 200. These areas are accurately determined based on the patient's lung images to ensure that the percussion device 100 can accurately act on the part that needs treatment.

[0053] According to a preferred embodiment, the knocker 100 that cooperates with the knocking clothing 200 is configured to determine its working mode according to the infection degree of each infected area determined by the image results.

[0054] The percussion garment 200 preferably also includes an analysis unit 220. The intelligent algorithm of the analysis unit 220 determines the working mode of the percussion device 100 for each treatment based on the image analysis results, the feedback data of each sensor, etc. The image analysis results include the degree of mucus accumulation, location and degree of infection of each lung lobe. The working mode of the percussion device 100 includes the activation time of the first mechanical energy applying part 110 and the second mechanical energy applying part 120, as well as the vibration intensity, percussion force and treatment duration of the first mechanical energy applying part 110 and the second mechanical energy applying part 120.

[0055] The analysis unit 220 of the tapping clothing 200 generates a tapping scheme according to the image analysis result, and the generated tapping scheme is sent to the tapping device 100. The tapping device 100 performs corresponding operations according to the tapping scheme. The tapping clothing 200 can dynamically adjust the tapping scheme according to the real-time feedback of the sensor.

[0056] The analysis unit 220 of the tapping garment 200 activates the target vibration area 210 in sequence according to the preset tapping scheme, and controls the timer 250 to start when the tapper 100 contacts the target vibration area 210. When the tapper 100 leaves the target vibration area 210, or reaches the preset time limit, the timer 250 stops automatically. The timer 250 continuously records the action time of the tapper 100 on each target vibration area 210, and sends these data to the analysis unit 220 of the tapping garment 200 for analysis and storage. Specifically, the patient puts on the tapping garment 200 and the tapper 100 is ready. The analysis unit 220 of the tapping garment 200 determines the first target vibration area 210 according to the preset treatment plan. Before the treatment starts, the progress indicator lights corresponding to all target vibration areas 210 are off, indicating that the treatment has not yet started. When the timer 250 starts, that is, the tapper 100 starts to act on a certain target vibration area 210, the progress indicator light corresponding to the area lights up, and different colors (such as red, green, blue, etc.) are usually used to indicate that the treatment in the prescribed manner is being carried out. The progress indicator light preferably displays the progress of the treatment in different ways according to the time recorded by the timer 250. For example, as the treatment time increases, the light gradually becomes brighter until it reaches the maximum brightness, indicating that the treatment is about to be completed; or, the color of the light can change with the progress of the treatment, for example, from blue to green, indicating that the treatment has been completed. When the timer 250 stops, that is, the tapper 100 completes the treatment of the target vibration area 210, the progress indicator light corresponding to the target vibration area 210 goes out or changes to other colors (such as green), indicating that the treatment of the area has been completed. According to the treatment plan, the analysis unit 220 of the tapping clothing 200 controls the tapper to automatically switch to the next target vibration area 210, and repeats the above process until the treatment of all areas is completed.

[0057] The first mechanical energy applying part 110 of the tapping device 100 includes a high-frequency vibration module 111. The high-frequency vibration module 111 includes a vibration generator, a vibration adjustment unit 112 and a vibration conduction device 113. The vibration generator is preferably composed of one or more small vibration motors, which can generate high-frequency vibrations (usually 5 to 25 Hz). The vibration motor is driven by compressed air or other power sources to generate rapid mechanical vibrations. The vibration adjustment unit 112 is responsible for adjusting the frequency, intensity and duration of the vibration. The vibration adjustment unit 112 can dynamically adjust the vibration parameters according to the feedback signal provided by the tapping clothing 200 to adapt to different airway conditions and treatment needs. The vibration conduction device 113 transfers the vibration energy from the vibration generator to the patient's body. The vibration conduction device 113 is, for example, a chest strap or other form of contact surface. The vibration generators are preferably arranged in an array on the tapping clothing 200 so that independent vibration generators cover multiple target vibration areas 210 on the patient's chest and back. Preferably, each vibration generator is equipped with a position sensor to locate the position of the vibration generator on the tapping clothing 200. The position sensor is connected to the analysis unit 220 of the tapping garment 200 in communication to control the vibration generator to act on the target vibration area 210. According to the tapping scheme generated by the patient's image analysis results, the analysis unit 220 of the tapping garment 200 sends a start instruction to the specified vibration generator. After receiving the instruction, the vibration generator starts to vibrate according to the preset vibration sequence, vibration frequency, vibration intensity and vibration duration of each target vibration area 210. At this time, the tapping sensor 240 monitors the vibration intensity in real time and transmits the feedback signal to the analysis unit 220 of the tapping garment 200.

[0058] The second mechanical energy applying part 120 of the tapper 100 includes a tapping / slapping module. The tapping / slapping module includes a tapping / slapping actuator 121, a force adjustment unit 122 and a tapping / slapping positioning device 123. The tapping / slapping actuator 121 is preferably composed of a set of programmable mechanical arms (connecting arms 160) or pneumatic hammers, which can selectively apply tapping or slapping. The tapping actuator can be driven pneumatically or electrically to generate a rhythmic mechanical impact force. The force adjustment unit 122 adjusts the force of the tapping or slapping. The force adjustment unit 122 dynamically adjusts the force according to the feedback signal provided by the tapping clothes 200 to adapt to the airway conditions and treatment needs of different patients. The tapping / slapping positioning device 123 is used to locate the target vibration area 210 for tapping or slapping. The tapping / slapping positioning device 123 preferably automatically adjusts the position of the tapping or slapping according to the lung image analysis results provided by the tapping clothes 200 to ensure the accuracy and pertinence of the treatment. Preferably, the tapping / slapping actuator 121 is mounted on one or more artificial intelligence controlled connecting arms 160. The slapping actuator simulates the effect of palm slapping through a lighter mechanical impact force. The connecting arm 160 of the tapping / slapping actuator 121 is equipped with a high-precision positioning system, such as electromagnetic induction technology, optical sensors, etc., to determine the position of the target vibration area 210 on the tapping clothing 200. An electromagnetic marker (such as a micro coil or magnetic material) can be embedded in the target vibration area 210 of the tapping clothing 200, and an electromagnetic sensor is installed on the connecting arm 160 of the actuator. When the actuator approaches the target area, the electromagnetic sensor can detect the presence of the electromagnetic marker and adjust the motion trajectory of the actuator according to its position information. Specifically, a three-dimensional magnetic field environment is created by arranging multiple electromagnetic transmitters inside the tapping clothing 200. A magnetic field sensor is installed on the connecting arm 160 of the tapping / slapping actuator 121, and the position of the target area can be accurately located according to the change of the magnetic field. This method can achieve high-precision positioning, and is particularly suitable for target area identification under complex anatomical structures.

[0059] Example 3

[0060] This embodiment is a further improvement of Embodiment 1, and repeated contents will not be repeated here.

[0061] The present embodiment provides another tapping system, which includes a tapper 100 and a tapping garment 200. The tapper 100 includes a first mechanical energy applying part 110 that achieves airway clearance in a vibration manner and a second mechanical energy applying part 120 that can selectively apply tapping or slapping to clear the airway. The tapper 100 and the tapping garment 200 cooperate with each other and switch the working mode according to the feedback signal given by the tapping garment 200. That is, the tapper 100 selectively activates the first mechanical energy applying part 110 or the second mechanical energy applying part 120, wherein when the second mechanical energy applying part 120 is activated, tapping or slapping is selectively applied.

[0062] According to this embodiment, the tapper 100 is configured to: when the feedback signal of the tapping garment 200 shows that the target vibration area 210 is the upper lobe of the lungs, activate the first mechanical energy applying part 110 to perform airway clearing on the target vibration area 210 .

[0063] The airway of the upper lobe is relatively thick, the airway diameter is large, and the airflow resistance is small. A larger airway diameter means that the airflow can enter and leave the area in a smoother way, reducing the possibility of mucus retention. In the upper lobe, the shear force generated by high-frequency vibration can act more effectively on the airway wall, destroying the adhesion between mucus and the airway wall. Therefore, mucus is easily discharged under the conditions of shear force generated by high-frequency vibration and airflow push and loosening. The first mechanical energy applying part 110, for example, provides a uniform vibration distribution for the right upper lobe and the left upper lobe. The vibration generated by the first mechanical energy applying part 110 can ensure that a large area of ​​mucus is loosened. Specifically, the airway of the upper lobe is thicker and the distribution is more concentrated. The vibration can cover the entire upper lobe area, ensuring that all mucus can be effectively loosened, and the mucus in the upper lobe is usually thinner and has a lower viscosity. The shear force of the vibration not only acts on the surface of the mucus, but also penetrates into the inside of the mucus, further destroying the structure of the mucus, reducing its viscosity, and increasing its fluidity. Therefore, for the airways of the upper lobe, the first mechanical energy applying part 110 alone can achieve effective mucus loosening and discharge.

[0064] According to this embodiment, the tapper 100 is configured as follows: when the feedback signal of the tapping clothing 200 shows that the target vibration area 210 is the middle lobe of the lung, the tapping working mode of the second mechanical energy applying part 120 is first enabled, and then the first mechanical energy applying part 110 is enabled to clear the airway of the target vibration area 210.

[0065] The airways in the middle lobe are relatively thin, especially in the right middle lobe (there is no middle lobe in the left lung), with more airway branches and greater airflow resistance. In addition, the airways in the middle lobe are more curved, especially in the right middle lobe, and the direction of the airways is more complicated. This structure makes it easier for mucus to be retained in the small branch airways and at the bends, forming mucus plugs and obstructing airway patency. Because the airways in the middle lobe are thin, high-frequency vibration alone may not be able to effectively loosen the mucus in these small branches, especially when the mucus is stubborn or has formed mucus plugs. Due to the large curvature of the airway, the shear force of high-frequency vibration may not act evenly on the entire airway wall, especially at the bends of the airway, where mucus may still adhere to the airway wall. At this time, a stronger mechanical impact force can be applied by slapping to destroy the adhesion between the mucus and the airway wall, helping to loosen these hard-to-reach mucus.

[0066] On the other hand, mucus in the middle lobe is usually stubborn, especially in diseases such as bronchiectasis and chronic bronchitis. The accumulation of mucus in the middle lobe is usually localized and concentrated in certain airway branches or areas. This allows tapping to act more precisely on the areas where mucus accumulates, producing a stronger local effect. And tapping is a gentle mechanical stimulation to help loosen these hard-to-reach mucus, so it will not cause excessive stimulation to the airway and will not increase the patient's discomfort.

[0067] As a pre-step, tapping quickly loosens the mucus in the middle lobe airway through gentle local mechanical stimulation, especially those stubborn mucus or already formed mucus plugs, creating conditions for subsequent high-frequency vibration. On the basis of tapping, high-frequency vibration can provide uniform vibration distribution, further enhance the fluidity of mucus, and ensure that the loosened mucus can be discharged smoothly. High-frequency vibration can also slightly expand the airway, increase the airflow speed, and help the mucus move to the large airways faster. This embodiment treats the middle lobe target area by tapping first and then high-frequency vibration. Furthermore, the treatment plan can be flexibly adjusted according to the specific situation of the patient. For example, for patients with more stubborn mucus, the strength and frequency of tapping can be appropriately increased; for patients with thinner mucus, the strength and frequency of tapping can be reduced, and more reliance can be placed on high-frequency vibration for airway clearance.

[0068] According to this embodiment, the tapper 100 is configured as follows: when the feedback signal of the tapping clothing 200 shows that the target vibration area 210 is the lower lobe of the lungs, the tapping working mode of the second mechanical energy applying part 120 is first enabled, and then the first mechanical energy applying part 110 is enabled to clear the airway of the target vibration area 210.

[0069] Compared with the middle lobe, the airway of the lower lobe is thinner, especially the right lower lobe and the left lower lobe, and the airway branches are more complex. The lower lobe is located at the bottom of the lungs, and under the influence of gravity, mucus tends to accumulate here. Gravity will cause mucus to move to the large airways, but it may also cause mucus to adhere more closely to the airway wall, increasing the difficulty of loosening. Due to the effect of gravity, the mucus in the lower lobe is often more stubborn and easy to form mucus plugs. This type of mucus is not easy to loosen by simple high-frequency vibration, and a stronger mechanical impact force is required to destroy its structure. Tapping can break the adhesion between mucus and the airway wall through a stronger mechanical impact force, ensuring that the mucus can be fully loosened. In this embodiment, tapping quickly loosens stubborn mucus or mucus plugs that have been formed through direct mechanical impact force. This local impact force can ensure that the mucus is fully loosened, creating better conditions for subsequent high-frequency vibration. On the basis of tapping, high-frequency vibration can provide a uniform vibration distribution, further enhance the fluidity of mucus, and ensure that the loosened mucus can be smoothly discharged.

[0070] The percussion force is strong, but the action time is short, and it only targets specific areas of mucus accumulation. By percussing first and then vibrating at high frequency, mucus can be quickly loosened in a short time to avoid excessive stimulation of the airway. This combination can reduce stimulation to the patient and improve the comfort and safety of treatment, especially in the case of thin airways and stubborn mucus in the lower lobe.
