[0035] Please refer to Figure 1 and Figure 2The first embodiment of the present application provides a cleanable handle 10 for a pulse therapy instrument; the cleanable handle 10 comprises a handle body 11, an air circuit 12, a filter bin 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 connecting structure for fixing the air circuit 12, the filter bin 13, the pulse generator 14, the gas output assembly 15 and the sensor assembly 16, the handle body 11 is detachably connected with the air circuit 12, the filter bin 13, the pulse generator 14 and the gas output assembly 15 through buckle, thread or quick release interface and the like, and the handle body 11 is used for fixing and protecting the sensor assembly 16. The air circuit 12, the filter bin 13, the pulse generator 14 and the gas output assembly 15 are sequentially communicated to form a gas supply channel of the cleanable handle 10; the filter bin 13, the pulse generator 14 and the gas output assembly 15 are detachably connected on the handle body 11, and then each component can be detached from the handle body 11 for comprehensive cleaning and disinfection, thereby avoiding the problem that the bacteria and impurities are left due to the integral setting and the inability to be detached, ensuring the use safety, avoiding cross infection, and also enabling any component to be replaced, maintained or repaired as required 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 air circuit 12 is used for connecting a compressed gas source, the air inlet end of the air circuit 12 is connected with the compressed gas source through a hose or a fixed interface, is used for receiving the compressed gas flow provided by the compression mechanism, and transmits the compressed gas flow to the filter bin 13; the filter bin 13 is used for filtering the impurities and particles in the compressed gas flow, so as to ensure that the gas entering the pulse generator 14 is clean and pollution-free. The filter bin 13 can be separated from the handle body 11, facilitating cleaning and replacement. The bottom of the filter bin 13 is provided with a communication interface connected with the sensor assembly 16 on the handle body 11, and the sensor assembly 16 is used for detecting the pressure or flow rate of the gas flow in the filter bin 13; it should be noted that the filter bin 13 of the filter bin 13 does not affect the passability of the drug; the pulse generator 14 is used for converting the compressed gas flow into a pulse gas flow, the pulse gas flow is transmitted to the user through the gas output assembly 15, and the sensor assembly 16 is communicated with the filter bin 13 and is used for detecting the gas flow parameters in the filter bin 13.

[0036] For further reference, please see Figure 3In some preferred embodiments, the top of the handle body 11 is provided with a filter mounting portion 111 and a tracheal tube fixing portion 112; the filter mounting portion 111 is a semi-annular groove structure, and the inner wall is provided with an elastic sealing ring for forming 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 tracheal tube component, thereby reducing the risk of misassembly and misplacement, and quickly resetting the components after multiple cleaning or maintenance, thereby reducing maintenance time and difficulty.

[0037] The filter bin 13 includes an upper bin body 131, a lower bin body 132, a filter air inlet 133, and a filter air outlet 134. After the compressed gas flow enters the filter cavity, solid impurities and particles can be effectively removed, ensuring that the gas flow transmitted to the pulse generator 14 is clean, protecting subsequent components, and improving treatment effect. The lower bin body 132 is detachably connected and sealed with the filter mounting portion 111 to form a filter cavity, and a plurality of filter core structures are arranged in the filter cavity, and the filter cavity is in communication with the sensor assembly 16. By arranging the upper bin body 131 and the lower bin body 132 of the filter bin 13 in a detachable connection, and arranging filter core structures in the filter cavity, the filter core replacement and cleaning operation is more convenient. When the filter core increases in resistance or decreases in filtering precision after being used for a period of time, the user can quickly remove the lower bin body 132 for filter core cleaning or replacement, thereby maintaining stable gas flow quality in long-term use. At the same time, the filter cavity is in communication with the sensor assembly 16, so that the sensor can monitor the state of the filtered gas in real time, so that the device can discover problems early before impurities accumulate or the filter core performance decays, and ensure the continuous stability of the gas flow parameters.

[0038] The filter air inlet 133 is arranged on the upper bin body 131 and is used to connect the air circuit 12. By arranging the filter air inlet 133 above the upper bin body 131, the natural distribution of gravity and gas flow direction can be utilized, so that the compressed gas flow is first filtered by the filter core layer and then enters the downstream assembly, thereby ensuring that the filter core surface always maintains a good working state after cleaning, and reducing the probability of filter core damage during disassembly.

[0039] The filter air outlet 134 is detachably connected to the tracheal tube fixing portion 112 and is used to connect the pulse generator 14. By designing a detachable connection interface at the position of the filter air outlet 134, the filtered gas can be flexibly introduced into the pulse generator 14. When the pulse generator 14 or the air outlet pipe needs to be cleaned or replaced, the pulse generator 14 part can be independently removed without disassembling other components, thereby reducing the equipment downtime in a frequent use environment and improving the equipment turnover efficiency of medical institutions.

[0040] It can be known that the lower bin body 132 of the filter bin 13 is detachably connected and sealed with the handle body 11 through the filter mounting portion 111, which facilitates quick disassembly of the filter bin 13, cleaning of the filter cavity and replacement of the filter element, and effectively solves the problem that the existing handle cannot be disinfected and cleaned.

[0041] Please refer to Figure 4 to Figure 7 In some preferred embodiments, the height of the filter mounting portion 111 is lower than that of the air pipe fixing portion 112, and a bearing platform is arranged on the filter mounting portion 111. The bearing platform is provided with a U-shaped sunken groove 113, the opening direction of the U-shaped sunken groove 113 is away from the air pipe fixing portion 112, and the U-shaped sunken groove 113 is provided with a groove bottom 1131, a first side groove wall 1132, a circular arc side groove wall 1133 and a second side groove wall 1134. The sensor assembly 16 can communicate with the filter bin 13 without interfering with other components by arranging a sensing butt joint hole 1135 on the groove bottom 1131. The first side groove wall 1132 and the second side groove wall 1134 are provided with limiting sliding grooves 1136, which can realize accurate guiding and limiting when the lower bin body 132 is installed. The circular arc transition structure of the circular arc side groove wall 1133 can reduce the probability of mutual friction damage of components during disassembly and assembly. Further, it provides a stable spatial positioning basis for installation, alignment and sealing of the filter bin 13, so that high-precision butt joint can be maintained after multiple filter element replacement and cleaning operations, thereby ensuring that the equipment maintains high sealing performance and sensing detection accuracy in long-term use.

[0042] The lower cartridge body 132 is provided with a bundle opening 1321 at the end away from the upper cartridge body 131, and the bundle opening 1321 is sequentially provided with an axial tapering portion 1322, an axial constant diameter portion 1323 and an inner diameter receiving portion 1324. The outer surface of the axial constant diameter portion 1323 is symmetrically distributed with two clamping structures 1325, and a anti-disengagement piece 18 is arranged between the two clamping structures 1325. The lower cartridge body 132 is matched with the limiting sliding groove 1136 through the clamping structure 1325, and when the lower cartridge body 132 is inserted along the U-shaped sink 113, the clamping structure 1325 can be slid to a predetermined position along the limiting sliding groove 1136 and be limited in the height direction, so as to form a stable and repeatable sealing connection in a suitable position. The presence of the anti-disengagement piece 18 makes the lower cartridge body 132 not accidentally disengaged under the condition of high-pressure gas flow or long-term use, reduces the complexity of secondary assembly alignment while maintaining long-term sealing quality, and prevents the lower cartridge body 132 from disengaging along the limiting sliding groove 1136. When the axial constant diameter portion 1323 is inserted into the sensing butt joint hole 1135, the filter cartridge 13 and the sensor assembly 16 realize information exchange in a closely fitted state, and the sensor butt joint process can be completed without the help of additional tools, simplifying the sensor fault diagnosis and maintenance work flow.

[0043] Optionally, the matching tolerance between the clamping structure 1325 and the limiting sliding groove 1136 can be slightly adjusted according to the material characteristics of the filter element, so as to cope with the slight deformation of the parts caused by changes in environmental temperature and humidity, and further guarantee the air tightness. Further, a wear-resistant coating can be added to the surface of the circular arc side groove wall 1133 or a material with low friction coefficient can be used to further reduce the wear caused by long-term disassembly, so as to maintain stable and easy-to-maintain structural characteristics under long-term operating conditions.

[0044] Further, the outer surface of the axial constant diameter portion 1323 is further provided with an anti-disengagement structure 1326, which is arranged between the two clamping structures 1325 and is clamped with the anti-disengagement piece 18; when disassembling the filter cartridge 13, the anti-disengagement piece 18 is disengaged from the anti-disengagement structure 1326 by pressing or lifting the anti-disengagement piece 18, thereby facilitating the disassembly of the filter cartridge 13.

[0045] Please refer to Figure 8 and Figure 9In some preferred embodiments, the pulse generator 14 comprises a pulse shell 141, a motor, a first magnetic force rotor and a second magnetic force rotor 144 to achieve pulse regulation of the airflow; the pulse shell 141 comprises a pulse partition plate 1411 and a motor mounting plate 1412 arranged between the pulse partition plate 1411 and the handle body 11; by adding the motor mounting plate 1412 between the pulse partition plate 1411 and the handle body 11, the motor is more easily repaired and replaced in an independent installation space, ensuring that the stability and accuracy of the motor assembly can be maintained after a period of operation. The pulse partition plate 1411 is provided with a pulse air inlet 1413, a pulse air outlet 1414 and a pulse shaft 1415, and the pulse air inlet 1413 is connected with the filter air outlet 134; direct connection of the pulse air inlet 1413 with the filter air outlet 134 allows the gas purified 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 quality of the gas in the pulse modulation process. The pulse air outlet 1414 is used to guide the gas that has completed pulse modulation to the downstream or exhaust path, so that the remaining 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 partition plate 1411; arranging the motor on the side away from the pulse partition plate 1411 makes it easier for the heat and vibration received by the motor in actual work to be dispersed, reducing interference with the magnetic coupling state between the pulse shaft 1415 and the magnetic force rotor and improving the stability of pulse frequency control. The first magnetic force rotor is arranged on the motor output shaft for synchronous rotation of the output shaft; synchronous rotation of the first magnetic force rotor with the motor output shaft allows the change in motor speed to be directly converted into pulse frequency adjustment, achieving continuous regulation from low frequency to high frequency and allowing the device to adapt to the treatment needs of different patients. The second magnetic force rotor 144 is arranged on the pulse shaft 1415 for synchronous rotation with the first magnetic force rotor to control the opening and closing of the pulse air inlet 1413 and the pulse air outlet at a preset frequency; through the magnetic coupling between the first and second magnetic force rotors 144, stable synchronization of the fan-shaped rotating elements in high-speed operation can be achieved without mechanical contact, reducing bearing wear and energy consumption, while still maintaining accurate opening and closing of the pulse air inlet 1413 and the pulse air outlet under high-pressure airflow to meet high-precision treatment airflow regulation. The pulse partition plate 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 shaft 1415 is located on the axis; symmetrical distribution of the pulse air inlet 1413 and the pulse air outlet on the same circle and placement of the pulse shaft 1415 at the center position make the load distribution of the rotating components more uniform during operation, which is conducive to maintaining the concentricity and rotational balance of the components during long-term operation, thereby reducing vibration and deviation and maintaining the stability and repeatability of pulse output.A cooperation gap 145 is provided between the motor mounting plate 1412 and the pulse outlet for discharging the exhaust gas discharged by the pulse outlet; the cooperation gap 145 between the motor mounting plate 1412 and the pulse outlet allows the gas unused in the pulse modulation or the excess gas to be smoothly discharged, and avoids unnecessary pressure accumulation of the residual gas on the inside of the pulse shell 141 in the high-pressure state. The design can improve the safety and durability of the equipment.

[0046] Further, in the present 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 also be adjusted according to the specific use scenario. For example, a more heat-resistant motor mounting plate 1412 material can be used to adapt to a high-temperature sterilization environment, or the surface of the magnetic rotor can be treated for corrosion resistance, or the pulse modulation performance can be maintained for a long time under the condition of humid or containing trace drug particles.

[0047] In some preferred embodiments, the second magnetic rotor 144 includes a shaft sleeve 1441, a first fan wing 1442, and a second fan wing 1443. The shaft sleeve 1441 is arranged on the pulse shaft 1415 and is prevented from being detached in the axial direction, so that the shaft sleeve 1441 does not slip or detach in high-speed rotation and long-term operation. When the motor output shaft drives the first magnetic rotor to rotate, the shaft sleeve 1441 acts as a mounting component of the second magnetic rotor 144, synchronously rotates, and maintains coaxiality with the pulse shaft 1415. Through this close fixing method, the concentricity and transmission stability of the shaft can be maintained under the condition of high-frequency pulse airflow generation.

[0048] The first fan wing 1442 and the second fan wing 1443 are arranged at different circumferential positions of the shaft sleeve 1441. When the first fan wing 1442 and the second fan wing 1443 alternately occupy the relative position of the pulse inlet 1413 and the pulse outlet, periodic opening and closing of the airflow can be achieved. With the change of the motor speed, the alternating blocking behavior of the two fan wings changes the on-off time between the pulse inlet 1413 and the pulse outlet, thereby achieving flexible adjustment of parameters such as pulse frequency and pulse duty cycle.

[0049] By adopting the design of two fan wings alternately opening and closing the inlet and outlet paths, the flow and frequency modulation are more accurate. For example, at a certain motor speed, if a higher frequency pulse output is required, the motor speed can be increased to complete the alternating work of the two fan wings in a short period, thereby improving the frequency and stability of the pulse output. Without additional mechanical transmission components, the structure is simplified, the friction and energy loss are reduced, and the consistency and reliability of the pulse output are improved.

[0050] Further, the shape, size and material of the fan wings can be further optimized. For example, in a high humidity or a gas flow environment containing trace amounts of drugs, the fan wings can be made of corrosion-resistant and wear-resistant materials to extend the service life; or by adjusting the thickness and curved shape of the fan wings, a relatively linear pulse frequency response can be obtained at different motor speeds.

[0051] Please refer to Figure 6 , Figure 10 and Figure 11 In some preferred embodiments, the handle body 11 is further provided with a receiving cavity 114, and a sensing sealing plate 115 is arranged at a position corresponding to the sensing docking hole 1135, so as to further improve the sealing and easy maintenance characteristics of the sensor assembly 16. The receiving cavity 114 is provided with the sensing sealing plate 115 at a position corresponding to the sensing docking hole 1135; by installing the sensing sealing plate 115 in the receiving cavity 114 at the position of the sensing docking hole 1135, an independent and controllable sealed space can be formed between the sensor assembly 16 and the filter bin 13. When the sensor assembly 16 needs to be cleaned, replaced or calibrated, it is not necessary to disassemble the handle body structure in a large area, and only the corresponding operation of the sensing sealing plate 115 can quickly access the sensor installation area, so as to shorten the maintenance time, and reduce the error probability and maintenance difficulty.

[0052] The sensing sealing plate 115 is provided with a sealing protruding rib 1151 and a vent 1152, and the sealing protruding rib 1151 is in clamping sealing with the inner diameter receiving portion 1324; the sealing protruding rib 1151 is arranged on the sensing sealing plate 115 and clamped at the position of the inner diameter receiving portion 1324, so as to provide a reliable sealing interface. After the change of high pressure gas flow or multiple cleanings, the sealing interface can still ensure the airtightness of the gas path, which helps to maintain the cleanliness and stability of the sensor measurement area. In long-term use and frequent maintenance, the existence of the sealing protruding rib 1151 reduces the gas leakage and sensor reading error caused by small gaps, and provides a more reliable basic environment for sensor measurement.

[0053] The vent 1152 is arranged on the end surface of the sensing sealing plate 115 in the receiving cavity 114, and communicates with the filter bin 13; by designing the vent 1152 on the sensing sealing plate 115 and making the vent 1152 communicate with the filter bin 13, the filtered clean gas flow can enter the receiving cavity 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.

[0054] Further, the relevant structure is adjusted according to different clinical needs or cleaning specifications; for example, the diameter and length of the air vent 1152 can be selected according to the airflow characteristics and sensor sensitivity to maintain the sensor fast response under specific airflow speed and pressure conditions; or a high-temperature-resistant and chemical-corrosion-resistant material is used on the material of the sealing convex rib 1151 to adapt to the high-temperature and high-pressure sterilization conditions and still maintain a stable sealing state. The clean and tight of the sensing area is maintained for a long time in the actual medical environment, and it is ensured that the sensor assembly 16 still provides accurate and reliable measurement data after high-frequency use and multiple disinfections.

By dividing the accommodation cavity 114 into the sensor cavity 1141 and the element cavity 1142, the physical isolation between the sensor assembly 16 and the element components such as the pulse generator 14 is ensured. The sensor cavity 1141 and the element cavity 1142 can be independent of each other, an independent space for assembling the sensor assembly 16 is arranged in the accommodation cavity 114, other electronic components in the element cavity 1142 are arranged in a sealed manner and are prevented from contacting the gas, thereby avoiding pollution; at the same time, when the sensor assembly 16 needs to be cleaned, replaced or calibrated, it is not necessary to disassemble the handle main body structure in a large area, the sensor mounting area can be quickly contacted by disassembling the sensor sealing plate 115, thereby shortening the maintenance time and reducing the error probability and maintenance difficulty.

[0056] At the same time, the sensor cavity 1141 is in communication with the filter bin 13 through the air 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. The isolation design can also effectively prevent the influence of heat, vibration or electromagnetic interference in the element cavity 1142 on the sensor, and improve the accuracy and stability of the sensor measurement data.

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, the sealing partition 117 is only needed to be disassembled to quickly take out the sensor assembly 16, thereby shortening the maintenance time and reducing the error probability. The connection mode of the sealing partition 117 and the sensor assembly 16 can be selected from a buckle type, a threaded type, or a magnetic adsorption type, so as to further improve the convenience of operation and the maintenance efficiency; when the sensor assembly 16 is assembled on the sealing partition 117, the electronic elements in the element cavity 1142 can be electrically connected with the sensor assembly 16.
