[0036] Please refer to Figure 1 and Figure 2The first embodiment of the present application provides a cleanable handle 10 for a pulse therapy device; the cleanable handle 10 includes a handle body 11, a ventilation circuit 12, a filter chamber 13, a pulse generator 14, a gas output assembly 15 and a sensor assembly 16. The handle body 11 is the main part held by the user, and is a connection structure for fixing the ventilation circuit 12, the filter chamber 13, the pulse generator 14, the gas output assembly 15 and the sensor assembly 16. The handle body 11 is detachably connected to the ventilation circuit 12, the filter chamber 13, the pulse generator 14 and the gas output assembly 15 by means of snaps, threads or quick-release interfaces. The handle body 11 is used to fix and protect the sensor assembly 16. The ventilation circuit 12, the filter chamber 13, the pulse generator 14 and the gas output assembly 15 are connected in sequence to form an air supply channel of the cleanable handle 10; the filter chamber 13, the pulse generator 14 and the gas output assembly 15 are detachably connected to the handle body 11, and then the above-mentioned components can be removed from the handle body 11 for comprehensive cleaning and disinfection, so as to avoid the problem of bacteria and impurities remaining due to the integral arrangement with the handle body 11 and the inability to be disassembled and disinfected, thereby ensuring safe use and avoiding cross infection. Any component thereof can also be replaced, maintained or repaired as needed without replacing the entire handle body 11, thereby reducing the use cost and maintenance difficulty; the sensor assembly 16 is arranged on the handle body 11, the ventilation circuit 12 is used to connect to a compressed air source, and the air inlet end of the ventilation circuit 12 is connected to the compressed air source through a hose or a fixed interface, so as to receive the compressed air flow provided by the compression mechanism and transmit the compressed air flow to the filter chamber 13; the filter chamber 13 is used to filter impurities and particles in the compressed air flow to ensure that the gas entering the pulse generator 14 is clean and pollution-free. The filter chamber 13 can be separated from the handle body 11 for easy cleaning and replacement. A communication interface is provided at the bottom of the filter chamber 13, which is connected to the sensor assembly 16 on the handle body 11. The sensor assembly 16 is used to detect the pressure or flow rate of the airflow in the filter chamber 13. It should be noted that the filter chamber 13 of the filter chamber 13 does not affect the permeability of the drug. The pulse generator 14 is used to convert the compressed airflow into a pulsed airflow, which is transmitted to the user through the gas output assembly 15. The sensor assembly 16 is connected to the filter chamber 13 to detect the airflow parameters in the filter chamber 13.

[0037] Please refer to further Figure 3In some preferred embodiments, a filter mounting portion 111 and an air pipe fixing portion 112 are provided on the top of the handle body 11; the filter mounting portion 111 is a semi-annular groove structure, and an elastic sealing ring is provided on the inner wall, which is used to form an airtight connection with the lower bin body 132 of the filter bin 13; a clear positioning reference can be obtained when installing or disassembling the filter bin 13 and the air pipe components, thereby reducing the risk of misinstallation and dislocation, and the components can still be quickly reset after multiple cleanings or maintenance, reducing maintenance time and difficulty.

[0038] The filter chamber 13 includes an upper chamber body 131, a lower chamber body 132, a filter air inlet 133 and a filter air outlet 134. After the compressed airflow enters the filter chamber, solid impurities and particles can be effectively removed, ensuring that the airflow transmitted to the pulse generator 14 is clean, protecting subsequent components, and improving the treatment effect; the lower chamber body 132 and the filter mounting portion 111 are detachably snap-fitted and sealed to form a filter chamber, in which a plurality of filter element structures are arranged, and the filter chamber is connected to the sensor assembly 16; by setting the upper chamber body 131 and the lower chamber body 132 of the filter chamber 13 in a detachable snap-fit ​​relationship, and arranging a filter element structure in the filter chamber, the filter element replacement and cleaning operations are made more convenient. When the filter element has increased resistance or decreased filtering accuracy after being used for a period of time, the user can quickly take out the lower chamber body 132 to clean or replace the filter element, thereby maintaining stable airflow quality during long-term use. At the same time, the filter chamber is connected to the sensor assembly 16, so that the sensor can monitor the state of the filtered gas in real time, so that the equipment can find problems early before impurities accumulate or filter performance decays, ensuring the continuous stability of airflow parameters.

[0039] The filter air inlet 133 is arranged on the upper storage body 131 for connecting to the ventilation circuit 12; by arranging the filter air inlet 133 above the upper storage body 131, gravity and the natural distribution of the airflow direction can be utilized to make the compressed air flow first filtered through the filter element layer and then enter the downstream components, thereby ensuring that the filter element surface is always in good working condition after cleaning and reducing the chance of filter element damage during disassembly and assembly.

[0040] The filter outlet 134 is detachably connected to the trachea fixing portion 112 and is used to connect the pulse generator 14. By designing a detachable connection interface at the filter outlet 134, the filtered gas can be flexibly introduced into the pulse generator 14. When the pulse generator 14 or the gas outlet pipe needs to be cleaned or replaced, the pulse generator 14 can be removed independently without disassembling other components, thereby reducing equipment downtime in a frequently used environment and improving the equipment turnover efficiency of medical institutions.

[0041] It can be seen that the lower chamber body 132 of the filter chamber 13 and the handle body 11 are detachably connected and sealed through the filter mounting portion 111, which facilitates the quick disassembly of the filter chamber 13, the cleaning of the filter chamber and the replacement of the filter element, and effectively solves the problem that the non-detachable handle in the prior art is difficult to disinfect and clean; through the sealing structure (such as a sealing ring) in the filter mounting portion 111, the filter chamber and the handle body 11 are efficiently sealed and connected, which can prevent gas leakage even in a high-pressure airflow environment.

[0042] Please refer to Figures 4 to 7 In some preferred embodiments, the height of the filter mounting portion 111 is lower than the trachea fixing portion 112, and a bearing platform is provided on the filter mounting portion 111. A U-shaped sinking groove 113 is provided in the bearing platform, and the opening direction of the U-shaped sinking groove 113 is provided away from the trachea fixing portion 112. The U-shaped sinking groove 113 has a groove bottom 1131, a first side groove wall 1132, an arc side groove wall 1133 and a second side groove wall 1134. A sensor docking hole 1135 is provided at the position of the groove bottom 1131, so that the sensor assembly 16 can be connected with the filter bin 13 without interfering with other components. By providing a limiting slide groove 1136 on the first side groove wall 1132 and the second side groove wall 1134, accurate guidance and limiting can be achieved when installing the lower bin body 132, and the arc transition structure of the arc side groove wall 1133 can reduce the probability of mutual friction and damage of components during disassembly and assembly. This provides a stable spatial positioning basis for the installation, alignment and sealing of the filter bin 13, so that high-precision docking can be maintained after multiple filter element replacement and cleaning operations, thereby ensuring that the equipment maintains high sealing and sensor detection accuracy during long-term use.

[0043] The lower bin body 132 is provided with a tie opening 1321 at one end away from the upper bin body 131, and the tie opening 1321 is provided with an axial tapered portion 1322, an axial constant diameter portion 1323 and an inner diameter receiving portion 1324 in sequence. Two clamping structures 1325 are symmetrically distributed on the outer surface of the axial constant diameter portion 1323, and an anti-slip member 18 is arranged between the two clamping structures 1325. The lower bin body 132 is matched with the limiting slide groove 1136 through the clamping structure 1325. When the lower bin body 132 is inserted along the U-shaped sink groove 113, the clamping structure 1325 can slide along the limiting slide groove 1136 to a predetermined position and be subject to the limiting constraint in the height direction, thereby forming a stable and repeatable sealed connection at a suitable position. The presence of the anti-slip part 18 prevents the lower bin body 132 from accidentally loosening under high-pressure airflow or long-term use conditions, thereby maintaining long-term sealing quality while reducing the complexity of secondary assembly alignment and preventing the lower bin body 132 from disengaging along the limiting slide groove 1136. When the axial constant diameter portion 1323 is inserted into the sensor docking hole 1135, the filter bin 13 and the sensor assembly 16 achieve information exchange in a tightly fitted state, and the sensor docking process can be completed without the aid of additional tools, simplifying the sensor fault diagnosis and maintenance workflow.

[0044] Optionally, the matching tolerance between the clamping structure 1325 and the limiting slide groove 1136 can be slightly adjusted according to the material characteristics of the filter element to cope with the slight deformation of the components caused by changes in ambient temperature and humidity, further ensuring air tightness. Furthermore, a wear-resistant coating or a low friction coefficient material can be added to the surface of the arc side groove wall 1133 to further reduce the wear caused by long-term disassembly and assembly, thereby maintaining a stable and easy-to-maintain structural characteristic under long-term operation conditions.

[0045] Furthermore, an anti-slip structure 1326 is provided on the outer surface of the axial constant diameter portion 1323, and the anti-slip structure 1326 is arranged between the two clamping structures 1325, and the anti-slip structure 1326 is clamped with the anti-slip part 18; when disassembling the filter bin 13, the anti-slip part 18 is disengaged from the anti-slip structure 1326 by pressing or lifting the anti-slip part 18, thereby facilitating the disassembly of the filter bin 13.

[0046] Please refer to Figure 8 and Fig. 9In some preferred embodiments, the pulse generator 14 includes a pulse housing 141, a motor, a first magnetic rotor and a second magnetic rotor 144 to achieve pulse regulation of the airflow; the pulse housing 141 includes a pulse baffle 1411, and a motor mounting plate 1412 arranged between the pulse baffle 1411 and the handle body 11; by adding a motor mounting plate 1412 between the pulse baffle 1411 and the handle body 11, the motor is easier to repair and replace in an independent installation space, ensuring that the stability and accuracy of the motor assembly can be maintained after running for a period of time. The pulse baffle 1411 is provided with a pulse air inlet 1413, a pulse exhaust port 1414 and a pulse shaft 1415. The pulse air inlet 1413 is connected to the filter air outlet 134. Directly connecting the pulse air inlet 1413 with the filter air outlet 134 allows the purified gas in the filter bin 13 to enter the pulse generator 14, reducing the wear of the pulse components caused by solid impurities and ensuring the gas quality during the pulse modulation process. The pulse exhaust port 1414 is used to guide the gas that has completed pulse modulation to the downstream or exhaust path, so that the residual gas or waste gas can be discharged in an orderly manner. The motor is arranged on the side of the motor mounting plate 1412 away from the pulse baffle 1411; the motor is arranged on the side away from the pulse baffle 1411, so that the heat and vibration effects on the motor in actual work can be more easily dispersed, reducing the interference with the magnetic coupling state between the pulse shaft 1415 and the magnetic rotor, and improving the stability of the pulse frequency control. The first magnetic rotor is arranged on the motor output shaft for synchronous rotation of the output shaft; the first magnetic rotor rotates synchronously with the motor output shaft, so that the motor speed change is directly converted into pulse frequency adjustment, realizing continuous regulation from low frequency to high frequency, so that the device can adapt to the treatment needs of different patients. The second magnetic rotor 144 is arranged on the pulse shaft 1415, and is used to rotate synchronously with the first magnetic rotor to control the pulse air inlet 1413 and the pulse air outlet to open and close at a preset frequency; through the magnetic coupling between the first and second magnetic rotors 144, the fan-shaped rotating elements can be stably synchronized in high-speed operation without mechanical contact, reducing bearing wear and energy consumption, and at the same time, the pulse air inlet 1413 and the pulse air outlet can still be opened and closed accurately under high-pressure airflow, meeting high-precision treatment airflow regulation. The pulse baffle 1411 has an axis, the pulse air inlet 1413 and the pulse air outlet are located on the same circle with the axis as the center, and the pulse rotating shaft 1415 is located on the axis; the pulse air inlet 1413 and the pulse air outlet are symmetrically distributed on the same circumference, and the pulse rotating shaft 1415 is placed at the center of the circle, so that the load distribution of the rotating parts is more uniform during operation, which is beneficial to maintaining the concentricity and rotational balance of the parts during long-term operation, thereby reducing vibration and deviation, and maintaining the stability and repeatability of the pulse output.A matching gap 145 is provided between the motor mounting plate 1412 and the pulse air outlet for discharging the waste gas discharged from the pulse air outlet; a matching gap 145 is provided between the motor mounting plate 1412 and the pulse air outlet so that the unused gas or excess gas from the pulse modulation can be discharged smoothly and avoid the residual gas under high pressure from causing unnecessary pressure accumulation inside the pulse housing 141. This design can improve the safety and durability of the equipment.

[0047] Furthermore, in this embodiment, the thickness of the motor mounting plate 1412, the material of the pulse shaft 1415, and the surface treatment of the magnetic rotor can be appropriately adjusted according to the specific usage scenario. For example, a more heat-resistant material of the motor mounting plate 1412 can be used to adapt to the high-temperature sterilization environment, or an anti-corrosion treatment can be performed on the surface of the magnetic rotor, or a treatment can be performed to maintain stable pulse modulation performance for a long time under humid or airflow conditions containing trace drug particles.

[0048] In some preferred embodiments, the second magnetic rotor 144 includes a shaft sleeve 1441, a first wing portion 1442, and a second wing portion 1443. The shaft sleeve 1441 is disposed on the pulse shaft 1415 and is provided with an anti-slipping arrangement in the axial direction, so that the shaft sleeve 1441 will not slide or loosen in the axial direction during high-speed rotation and long-term operation. When the motor output shaft drives the first magnetic rotor to rotate, the shaft sleeve 1441, as a mounting component of the second magnetic rotor 144, rotates synchronously and maintains coaxiality with the pulse shaft 1415. Through this tightly fixed method, the eccentricity and transmission stability of the shaft can be maintained under the condition of high-frequency pulse airflow generation.

[0049] The first wing portion 1442 and the second wing portion 1443 are respectively arranged at different circumferential positions of the rotating shaft sleeve 1441. When the first wing portion 1442 and the second wing portion 1443 are alternately located at the relative positions of the pulse air inlet 1413 and the pulse air outlet, the periodic opening and closing of the airflow can be realized. As the motor speed changes, the alternating shielding behavior of the two wing portions will change the on-off time between the pulse air inlet 1413 and the pulse air outlet, thereby realizing flexible adjustment of parameters such as pulse frequency and pulse duty cycle.

[0050] By using the design of two fan wings to alternately open and close the air inlet and outlet passages, the flow and frequency modulation are made more precise. For example, at a specific motor speed, if a higher frequency pulse output is required, the motor speed can be increased to complete the alternating operation of the two fan wings in a shorter period, thereby improving the frequency and stability of the pulse output. In a structure that does not require additional mechanical transmission components, it not only simplifies the structure, reduces friction and energy loss, but also improves the consistency and reliability of the pulse output.

[0051] Furthermore, the shape, size and material of the wing can be optimized appropriately. For example, in an environment with high humidity or airflow containing trace amounts of drugs, corrosion-resistant and wear-resistant materials can be selected to make the wing to extend its service life; or by adjusting the thickness and curved surface shape of the wing, a more linear pulse frequency response can be obtained at different motor speeds.

[0052] Please refer to Figure 6 , Fig.10 and Fig.11 In some preferred embodiments, the handle body 11 is further provided with a receiving chamber 114, and a sensing sealing plate 115 is provided at a position corresponding to the sensing docking hole 1135, so as to further enhance the sealing and easy-maintenance characteristics of the sensor assembly 16. The sensing sealing plate 115 is provided at a position corresponding to the sensing docking hole 1135 in the receiving chamber 114; by installing the sensing sealing plate 115 at the position of the sensing docking hole 1135 in the receiving chamber 114, an independent and controllable sealed space can be formed between the sensor assembly 16 and the filter chamber 13. When the sensor assembly 16 needs to be cleaned, replaced or calibrated, there is no need to disassemble the handle body structure on a large scale, and only the sensing sealing plate 115 needs to be operated accordingly to quickly access the sensor installation area, thereby shortening the maintenance time while reducing the error probability and maintenance difficulty.

[0053] The sensor sealing plate 115 is provided with a sealing rib 1151 and a vent 1152, and the sealing rib 1151 is snap-fitted and sealed with the inner diameter receiving portion 1324; the sealing rib 1151 is provided on the sensor sealing plate 115 so that it is snap-fitted to the position of the inner diameter receiving portion 1324, providing a reliable sealing interface. The airtightness of the air path can still be ensured after changes in the high pressure of the air flow or multiple cleanings, which helps to keep the sensor measurement area clean and stable. During long-term use and frequent maintenance, the presence of the sealing rib 1151 reduces airflow leakage and sensor reading inaccuracy caused by tiny gaps, providing a more reliable basic environment for sensor measurement.

[0054] The vent 1152 is arranged on the end face of the sensor sealing plate 115 located in the accommodating chamber 114 and is connected to the filter chamber 13. By designing the vent 1152 on the sensor sealing plate 115 and connecting the vent 1152 with the filter chamber 13, the filtered clean airflow can enter the accommodating chamber 114 where the sensor is located. The sensor can thus continuously receive the filtered and purified gas, thereby reducing the interference of particulate matter and humidity changes on the sensing accuracy, and laying a good foundation for long-term accurate measurement.

[0055] Furthermore, the relevant structures can be appropriately adjusted according to different clinical needs or cleaning specifications; for example, the diameter and length of the vent 1152 can be selected according to the airflow characteristics and sensor sensitivity to maintain the rapid response of the sensor under specific airflow speed and pressure conditions; or the sealing rib 1151 can be made of high temperature resistant and chemical corrosion resistant materials to adapt to high temperature and high pressure sterilization conditions and still maintain a stable sealing state. This can achieve long-term maintenance of the cleanliness and tightness of the sensing area in the actual medical environment, ensuring that the sensor assembly 16 can still provide accurate and reliable measurement data after high frequency use and multiple disinfections.

[0056] Please continue to refer to Fig.11 In some preferred embodiments, the accommodating chamber 114 includes a sensor chamber 1141 and an element chamber 1142 that are isolated from each other. The sensor chamber 1141 is connected to the filter chamber 13 through the vent 1152, and the sensor assembly 16 is arranged in the sensor chamber 1141. By dividing the accommodating chamber 114 into the sensor chamber 1141 and the element chamber 1142, the physical isolation between the sensor assembly 16 and the pulse generator 14 and other components is ensured. The sensor chamber 1141 and the element chamber 1142 can be independent of each other, and an independent space for assembling the sensor assembly 16 is set in the accommodating chamber 114, and other electronic components in the element chamber 1142 are sealed and avoid contact with gas, thereby avoiding contamination; at the same time, when the sensor assembly 16 needs to be cleaned, replaced or calibrated, there is no need to disassemble the handle main structure on a large scale, and the sensor sealing plate 115 can be disassembled to quickly access the sensor installation area, thereby shortening the maintenance time and reducing the error probability and maintenance difficulty.

[0057] At the same time, the sensor cavity 1141 is connected to the filter chamber 13 through the vent 1152, so that the sensor can receive the filtered clean airflow, thereby monitoring the airflow parameters such as pressure and flow rate in real time. This isolation design can also effectively prevent the heat, vibration or electromagnetic interference in the element cavity 1142 from affecting the sensor, thereby improving the accuracy and stability of the sensor measurement data.

[0058] Please continue to refer to Fig.11 In some preferred embodiments, the handle body 11 is further provided with an ultraviolet disinfection component 116, which is located in the sensor cavity 1141. By introducing the ultraviolet disinfection component 116 into the sensor cavity 1141, the interior of the sensor cavity 1141 can be ultraviolet disinfected when the device is idle or undergoes regular maintenance, thereby inhibiting the growth of bacteria and pathogenic microorganisms, so that a clean measurement environment can be maintained during the continuous use cycle, and even in a medical environment that is prone to the growth of bacteria such as high humidity and high temperature, the service life of the sensor can be extended and the measurement accuracy can be maintained.

[0059] Please continue to refer to Fig.11 In some preferred embodiments, a sealing partition 117 is provided between the sensor cavity 1141 and the element cavity 1142, and the sensor assembly 16 can be detachably connected to the sealing partition 117. When the sensor assembly 16 needs to be replaced, the sensor needs to be calibrated and maintained, or the sensor assembly 16 needs to be sterilized, there is no need to disassemble the entire machine on a large scale. The sensor assembly 16 can be quickly removed by removing the sealing partition 117, thereby shortening the maintenance time and reducing the probability of error. The connection method between the sealing partition 117 and the sensor assembly 16 can be selected from snap-on, threaded, or magnetic adsorption, etc., to further improve the convenience of operation and maintenance efficiency; when the sensor assembly 16 is assembled on the sealing partition 117, it can be electrically connected to the electronic components in the element cavity 1142.

[0060] Please refer to Figure 1 and Figure 4 In some preferred embodiments, the cleanable handle 10 is also provided with a data transmission component 17, and the data transmission component 17 is used for power supply and data transmission. The sensor component 16 and the pulse generator 14 are powered by the data transmission component 17, and the sensor component 16 and the pulse generator 14 are controlled by the data transmission component 17; at the same time, the cleanable handle 10 can also be communicated with the device host through the data transmission component 17.

[0061] Please refer to Figure 1 and Figure 2 In some preferred embodiments, the gas output assembly 15 includes a bite portion 151, a sputum collecting bottle 152 and a nose clip 153. One end of the bite portion 151 is connected to the pulse generator 14, and the other end of the bite portion 151 is used to connect to the user's mouth; the sputum collecting bottle 152 is detachably arranged at the lower end of the bite portion 151, and the nose clip 153 is integrally formed at the upper end of the bite portion 151. Furthermore, the other end of the bite portion 151 is used to connect to the user's mouth as a user end 1511, and the user end 1511 is provided with a detachable bite sleeve 1512; and the bite sleeve 1512 can be replaced when used by different users, so as to further avoid cross infection.

[0062] A second embodiment of the present application provides a pulse therapy device, which includes a cleanable handle as described above, so that the handle of the pulse therapy device can be disassembled and disinfected by removing the relevant structures of the air path when used by different users.

[0063] In summary, the present application provides a cleanable handle and a pulse therapy device, wherein the cleanable handle comprises: a handle body, a ventilation circuit, a filter chamber, a pulse generator, a gas output assembly and a sensor assembly, wherein the ventilation circuit, the filter chamber, the pulse generator and the gas output assembly are connected in sequence, wherein the filter chamber, the pulse generator and the gas output assembly are detachably connected to the handle body, wherein the sensor assembly is arranged on the handle body, wherein the ventilation circuit is used to connect a compressed gas source, wherein the pulse generator is used to convert the compressed gas flow into a pulse gas flow, wherein the pulse gas flow is transmitted to the user through the gas output assembly, and wherein the sensor assembly is connected to the filter chamber and is used to detect the gas flow parameters in the filter chamber. The cleanable handle can be detachably connected to the handle body by the ventilation circuit, the filter chamber, the pulse generator and the gas output assembly, and then the above-mentioned components can be removed from the handle body for comprehensive cleaning and disinfection, thereby avoiding the problem of bacteria and impurities remaining due to the inability to be integrated with the handle body and the inability to be disassembled and disinfected, thereby ensuring safe use and avoiding cross infection, and any of the components can be replaced, maintained or repaired as needed without replacing the entire handle body, thereby reducing the use cost and maintenance difficulty.
