[0001] This invention belongs to the field of medical nebulization equipment technology, specifically relating to a medical mesh nebulizer for water-soluble Chinese herbal extracts. Background Technology

[0002] With the advancement of the modernization of traditional Chinese medicine, nebulized herbal medicine therapy has shown significant advantages in the treatment of respiratory diseases such as chronic pharyngitis, asthma, and bronchitis because it can directly deliver effective ingredients to the respiratory tract lesions, increasing local drug concentration and reducing systemic side effects. However, the complex composition of water-soluble herbal extracts places stringent requirements on the compatibility, stability, and safety of nebulization equipment.

[0003] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a medical mesh nebulizer specifically for water-soluble Chinese herbal extracts.

[0004] Because the microfibers, protein coagulations, precipitated particles, and macromolecular components such as polysaccharides and colloids in the extracts of traditional Chinese medicine are easily adsorbed, deposited, and crystallized in the micropores and channels of the atomizing membrane, the micropores become blocked, causing a sharp drop in atomization efficiency, equipment performance degradation, or even damage, making cleaning and maintenance difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a medical mesh nebulizer specifically for water-soluble Chinese herbal extracts. It can solve the problem that microfibers, protein coagulations, precipitated particles, and macromolecular components such as polysaccharides and colloids in Chinese herbal extracts are easily adsorbed, deposited, and crystallized in the micropores and channels of the nebulizer membrane, leading to micropore blockage, a sharp drop in nebulization efficiency, equipment performance degradation, or even damage, and making cleaning and maintenance difficult.

[0006] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution: A medical mesh nebulizer specifically for water-soluble Chinese herbal extracts, comprising a housing and a controller; It also includes atomizing components; The atomizing assembly includes a liquid storage box, a filter box, a gas delivery pipe, an ultrasonic generator, a vibrating mesh, and a pre-filter membrane. The liquid storage box is fixed inside the shell and stores Chinese medicine liquid for atomization. The ultrasonic generator is fixed inside the shell, located on one side of the liquid storage box and connected to the liquid storage box. The ultrasonic generator can generate high-frequency vibration. The filter box contains a pre-filter membrane and a vibrating mesh membrane. The pre-filter membrane and the vibrating mesh membrane are arranged parallel to each other in the filter box. The pre-filter membrane is located below the vibrating mesh membrane and is positioned near the bottom of the filter box. The vibrating membrane further filters the atomized medicine solution after the pre-filter membrane has been filtered. The vibrating membrane is made of titanium alloy. The filter box and the breathing mask are connected by an air supply tube, through which the atomized medicine is delivered to the breathing mask.

[0007] In one or more embodiments of the present invention, the liquid storage box is a transparent box with scale lines marked on the outer wall, and a micro drive pump is provided inside the liquid storage box; The drive pump is used to drive the Chinese medicine liquid into the ultrasonic generator, and the operating speed of the drive pump can be adjusted according to actual needs. The connecting parts between the drive pump and the liquid storage box are made of corrosion-resistant materials.

[0008] In one or more embodiments of the present invention, the pore size of the pre-filter membrane is 10μm to 20μm, it is made of corrosion-resistant and high-temperature resistant material, and both the pre-filter membrane and the vibrating mesh membrane can be detachably fixed in the filter box. The filter box has an openable sealing cover on top.

[0009] In one or more embodiments of the present invention, the gas delivery tube is made of medical-grade silicone. The gas delivery pipe is detachably fixed between the filter box and the housing.

[0010] In one or more embodiments of the present invention, the inner wall of the gas transmission pipe is provided with a hydrophobic coating; A water tank is fixed to the outside of the shell. Both ends of the water tank are connected to the air supply pipes. One end is connected to the air supply pipe on the filter box side, and the other end is connected to the air supply pipe on the breathing mask side. The water storage tank adopts a double-layer heat insulation structure. The liquid stored inside can cool and heat the atomized medicine. The top of the water storage tank is equipped with a removable sealing cap.

[0011] In one or more embodiments of the present invention, the operating frequency of the ultrasonic generator can be adjusted according to the characteristics of the liquid, and the connection between the ultrasonic generator and the liquid storage box adopts a sealed design.

[0012] In one or more embodiments of the present invention, the side wall of the housing is provided with a power interface, and the interface is equipped with a dust cover; The power interface supports a wide voltage input.

[0013] In one or more embodiments of the present invention, a cylindrical rod-shaped support leg is fixed to the bottom of the housing; A rubber pad is fixed to the bottom of the support leg.

[0015] In one or more embodiments of the present invention, the micro drive pump is linked and adapted to the ultrasonic generator, and the operating speed adjustment range of the drive pump matches the operating frequency adjustment range of the ultrasonic generator.

[0016] Compared with the prior art, the present invention provides a medical mesh nebulizer specifically for water-soluble traditional Chinese medicine extracts: By adding a removable primary filter membrane at the bottom of the liquid chamber, tiny fibers, protein coagulations, or other invisible precipitates that may exist in the herbal extract are pre-intercepted before the liquid reaches the vibrating mesh membrane. The vibrating mesh membrane can greatly reduce the adsorption and deposition of sugars, colloids, and proteins in the herbal extract on the pore walls. This solves the problem that herbal extracts are easily adsorbed, deposited, and crystallized in the micropores and channels of the atomizing mesh membrane, leading to micropore blockage and a sharp drop in atomization efficiency. This invention avoids clogging of the atomizer by precipitates in the herbal extract, ensuring that the atomization effect is not affected. As a result, a special mesh atomizer is provided that is anti-clogging, provides room temperature atomization, has low residue, and can maintain the efficacy of the herbal medicine.

[0020] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0021] like Figures 1 to 4 As shown, a medical mesh nebulizer for water-soluble traditional Chinese medicine extracts according to one embodiment of the present invention includes a housing 101 and a controller 104. The controller 104 is fixed to the top of the housing 101 and is used to control the operation of the nebulization component 200. The nebulizer is operated through the controller 104. The nebulization component 200 is placed inside the housing 101. The nebulization component 200 includes a liquid storage box 201, a filter box 203, an air supply tube 205, an ultrasonic generator 207, a vibrating mesh 208, and a pre-filter membrane 209. 09; The liquid storage box 201 is fixed inside the housing 101. The liquid storage box 201 stores the traditional Chinese medicine liquid for atomization. The ultrasonic generator 207 is fixed inside the housing 101. The ultrasonic generator 207 is located on one side of the liquid storage box 201 and is connected to the liquid storage box 201. The ultrasonic generator 207 can generate high-frequency vibration, which atomizes the liquid stored in the liquid storage box 201 into tiny particles. The atomized liquid enters the filter box 203. The filter box 203 is fixed with a pre-filter membrane 209 and a vibrating mesh membrane 208. The filter membrane 209 and the vibrating mesh membrane 208 are arranged parallel to each other inside the filter box 203. The pre-filter membrane 209 is located below the vibrating mesh membrane 208 and is positioned near the bottom of the filter box 203. The atomized medicine entering the filter box 203 first passes through the pre-filter membrane 209, filtering the medicine and pre-intercepting tiny fibers, protein coagulations, or other precipitated particles present in the herbal extract. The vibrating mesh membrane 208 then filters the atomized medicine again after the pre-filter membrane 209 has filtered it. Made of titanium alloy, it can intercept tiny fibers, protein coagulations, or other precipitated particles while reducing the adsorption and deposition of sugars, colloids, and proteins in the nebulized medicine on the pore walls. This prevents large molecular components such as polysaccharides and proteins from the traditional Chinese medicine extract from remaining in the nebulizer's pipes, ensuring that the nebulizer is not clogged by residual medication. The filter cartridge 203 and the breathing mask are connected by an air delivery tube 205, through which the nebulized medicine is delivered to the breathing mask. The breathing mask is worn on the user's face, and the nebulized traditional Chinese medicine is inhaled by the user.

[0022] Preferably, the filter box 203 is a rectangular box. The filter box 203 and the ultrasonic generator 207 are connected by an air supply pipe. The atomized medicine is delivered into the filter box 203 through the air supply pipe. The air supply pipe is detachably fixed between the filter box 203 and the outer shell. The air supply pipe 205 is made of medical silicone, which has good flexibility and corrosion resistance, and can effectively prevent the medicine from leaking or being contaminated during delivery.

[0023] Preferably, the top of the filter box 203 is provided with an openable sealing cover, and the pre-filter membrane 209 and the vibrating mesh membrane 208 are detachably fixed inside the filter box 203, which makes it convenient for users to regularly clean and replace the pre-filter membrane 209 and the vibrating mesh membrane 208, thereby ensuring the long-term stable operation of the atomizer and preventing the pre-filter membrane 209 and the vibrating mesh membrane 208 from being blocked and affecting their filtration effect.

[0024] Preferably, the inner wall of the gas delivery tube 205 is provided with a hydrophobic coating, which can prevent the medicine from remaining in the gas delivery tube 205.

[0026] Preferably, the outer wall of the liquid storage box 201 is marked with graduation lines to facilitate users in accurately controlling the amount of medicine to be added.

[0027] Preferably, the operating frequency of the ultrasonic generator 207 can be adjusted according to the characteristics of the medicinal liquid to adapt to different types of Chinese herbal extracts. The connection between the ultrasonic generator 207 and the liquid storage box 201 is sealed to ensure that no leakage of medicinal liquid occurs during high-frequency vibration.

[0028] Preferably, the controller 104 is also equipped with a multi-functional display screen, which can display the working status of the nebulizer, the remaining liquid level, and fault alarm information in real time, providing users with an intuitive operating experience.

[0029] Preferably, a water tank 204 is fixed to the outside of the housing 101. The water tank 204 is connected to the air delivery tube 205, and the other end of the water tank 204 is connected to the breathing mask through the air delivery tube 205. The liquid stored in the water tank 204 can cool or heat the nebulized medication, ensuring that the patient feels a comfortable temperature during inhalation. The water tank 204 is designed with a double-layer heat insulation structure, which can effectively maintain the temperature stability of the liquid and avoid affecting the efficacy due to changes in the external ambient temperature.

[0030] Preferably, the gas delivery tubes 205 are all made of medical-grade silicone, which can effectively prevent leakage of the medicine during delivery.

[0031] Preferably, the side wall of the housing 101 is provided with a power interface 102, and the interface is equipped with a dust cover to protect the interface from dust and impurities when not in use. The power interface 102 supports wide voltage input to adapt to the power standards of different regions and provide users with a more convenient user experience.

[0032] Preferably, the liquid storage box 201 is equipped with a drive pump 206, which is a micro pump. The drive pump 206 drives the traditional Chinese medicine liquid into the ultrasonic generator 207. The operating speed of the drive pump 206 can be adjusted according to actual needs to meet the atomization requirements of different concentrations of liquid medicine. The connecting parts between the drive pump 206 and the liquid storage box 201 are made of corrosion-resistant materials, which can effectively resist the corrosion of the equipment by acid and alkali components that may exist in the traditional Chinese medicine extract, thereby improving the overall durability.

[0033] Preferably, the top of the water tank 204 is equipped with a removable sealing cap, which facilitates regular cleaning and replacement of the liquid by the user. The connection between the water tank 204 and the gas supply pipe 205 is equipped with a filter screen, which can further filter the gas entering the breathing mask, thereby improving the safety and reliability of the treatment.

[0034] Preferably, the pre-filter membrane 209 has a pore size of 10μm to 20μm, which can effectively intercept larger particulate impurities in the liquid medicine and ensure that the liquid medicine output by the nebulizer has a high purity. The pre-filter membrane 209 is made of corrosion-resistant and high-temperature resistant material, which can maintain stable performance during long-term use.

[0035] Preferably, a support leg 103 is fixed to the bottom of the outer shell. The support leg 103 is a cylindrical rod, and a rubber pad is fixed to the bottom of the support leg 103. The design of the rubber pad can effectively increase the stability of the atomizer when it is placed, and avoid displacement caused by equipment vibration or external factors.

[0036] Preferably, the vibrating membrane 208 has a nano-hydrophobic and oleophobic coating on its surface. This coating effectively prevents medication residue and clogging, ensuring that the vibrating membrane 208 maintains its high-efficiency atomization performance even after prolonged use. It also improves the membrane's durability, reducing the inconvenience of frequent cleaning or replacement. The hydrophobic and oleophobic properties allow the medication to disperse rapidly upon contact with the membrane, resulting in uniformly fine and evenly distributed atomized medication particles, providing patients with a more comfortable inhalation experience.

[0037] Preferably, the pore size of the vibrating membrane 208 is 3μm to 5μm, which can effectively filter out tiny impurities in the liquid medicine and ensure that the purity of the liquid medicine after atomization meets medical standards.

[0038] Preferably, a pressure sensor is provided between the liquid storage box 201 and the ultrasonic generator 207. The pressure sensor can monitor the pressure changes during the liquid delivery process in real time. When the liquid delivery pressure is abnormal, the controller 104 will automatically adjust the running speed of the drive pump 206 to ensure the stability and safety of the atomization process. The pressure sensor uses a high-precision sensing element, which can provide feedback on pressure data in a very short time, effectively avoiding poor atomization effect or equipment failure caused by pressure fluctuations.

[0039] Preferably, the breathing mask adopts an ergonomic design, which fits the facial contours while ensuring wearing comfort. The mask has a silicone sealing ring inside, which can effectively prevent leakage of nebulized liquid during delivery and ensure maximum drug utilization. The breathing mask is equipped with a one-way valve at the air inlet to prevent backflow of outside air and ensure that the patient inhales only filtered and nebulized liquid.

[0040] Preferably, the controller 104 has a built-in smart chip that can record user data and generate treatment reports. Through wireless transmission technology, the treatment data can be synchronized to a mobile terminal, making it convenient for doctors to remotely monitor the patient's treatment.

[0041] Preferably, the surface of the housing 101 is treated with an antibacterial coating, which can effectively inhibit bacterial growth and ensure that the equipment maintains a good hygienic condition after multiple uses.

[0042] Preferably, the nebulizer has a compact overall design, making it easy to carry and store, and suitable for use in various scenarios such as home and hospital. At the same time, the multi-functional display screen on the controller 104 supports multi-language switching to meet the needs of users in different regions, enhancing the applicability and popularity of the product. When the device detects insufficient medication or abnormal conditions, it will automatically stop operating and issue a warning sound to avoid damage to the device or affect the treatment effect due to misoperation. Furthermore, all parts that come into contact with the medication are made of medical-grade materials to ensure that they are non-toxic and harmless, and can withstand high-temperature sterilization, meeting strict hygiene requirements.

[0043] Preferably, the controller 104 has a built-in MCU to coordinate the operation of the atomizing component 200, the closed-loop control mechanism and the inhalation sensing system, ensuring smooth linkage of each functional module. The closed-loop control mechanism based on current feedback is designed to solve the problems of unstable atomization volume, easy clogging and dry burning risk caused by the fixed frequency and power operation of traditional mesh atomizers. The closed-loop control mechanism monitors the load current of the ultrasonic generator 207 drive circuit in real time through the MCU, and indirectly judges the equipment operating status and the condition of the medicine by utilizing the correlation between the load current and the viscosity of the medicine and the permeability of the vibrating mesh 208. Specifically, the change in load current is positively correlated with the viscosity of the medicinal solution and negatively correlated with the permeability of the vibrating membrane 208: when the viscosity of the water-soluble Chinese herbal extract increases, or when the micropores of the vibrating membrane 208 show a slight tendency to become clogged due to the macromolecular components of the Chinese herbal medicine, the operating load of the ultrasonic generator 207 increases, and the load current of the corresponding drive circuit rises synchronously; after the MCU detects this current change, it immediately calls the preset algorithm to automatically and slightly increase the drive voltage and operating frequency, thereby enhancing the vibration intensity of the ultrasonic generator 207, and "breaking open" the blockage through high-frequency vibration. The micropores of the membrane ensure unobstructed atomization channels and maintain stable atomization volume, preventing insufficient atomization from affecting the treatment effect. Conversely, when the medication in the reservoir 201 is gradually depleted, the load on the ultrasonic generator 207 is significantly reduced, and the load current of the drive circuit is also significantly reduced. After the MCU recognizes this signal, it quickly and automatically cuts off the output, stopping the operation of the ultrasonic generator 207 and the drive pump 206, effectively preventing the equipment from burning out and extending the service life of the core components. At the same time, an alarm prompt for depleted medication is issued through the multi-function display screen of the controller 104, reminding the user to replenish the medication in time.

[0044] To address the medication waste caused by the need for manual switching or continuous operation of traditional nebulizers, this embodiment integrates an intelligent inhalation sensing and energy-saving system. This system includes a micro-pressure sensor integrated into the air delivery tube 205 near the breathing mask. This sensor is connected to the MCU signal and is used to detect pressure changes within the breathing tubing in real time, enabling intelligent linkage between nebulization operation and the patient's breathing. When the patient inhales while wearing the breathing mask, a negative pressure is created within the breathing tubing. The micro-pressure sensor quickly detects this negative pressure signal and transmits it to the MCU. Upon receiving the signal, the MCU immediately activates the ultrasonic generator. The ultrasonic generator 207 and drive pump 206 initiate the nebulization process, ensuring the nebulized medication is precisely inhaled by the patient during inhalation. When the patient exhales, the breathing tubing becomes positively pressurized. The micro-pressure sensor transmits the positive pressure signal to the MCU, which then controls the ultrasonic generator 207 and drive pump 206 to pause operation, stopping nebulization. This intelligent linkage function avoids waste caused by continuous nebulization during the patient's exhalation phase. Actual testing has verified that it can reduce medication waste by more than 30%, making it particularly suitable for water-soluble traditional Chinese medicine extracts with complex components and high preparation costs. While ensuring therapeutic efficacy, it significantly reduces treatment costs for patients. Simultaneously, the energy-saving system reduces the ineffective operating time of core components by starting and stopping the equipment on demand, further improving the equipment's endurance and overall durability.

[0045] Preferably, the two newly added functions work in conjunction with the original structure of the equipment: the closed-loop control mechanism ensures the stability and safety of the nebulization process, and the intelligent inhalation sensing system improves drug utilization and energy saving. Combined with the existing design, including the titanium alloy nano-coated vibrating membrane 208, the multi-stage filtration structure, and the temperature regulation of the water tank 204, this forms a highly efficient, safe, and intelligent medical nebulization solution suitable for water-soluble Chinese herbal extracts, which can be widely applied in TCM clinical nebulization therapy scenarios. The nebulizer of this invention also has good compatibility and can be adapted to various types of breathing masks to meet the personalized needs of different patients. Whether used for adults or children, it can achieve the best therapeutic effect through simple adjustments.

[0046] In practical use, an automated stamping device for motor rotor laminations according to an embodiment of this application is as follows: The prepared water-soluble traditional Chinese medicine extract solution is injected into the transparent storage box 201 through the injection tube 202. After injection, the one-way valve on the injection tube 202 automatically closes, effectively preventing backflow of the solution and blocking external impurities from entering the storage box 201. The micro-drive pump 206 inside the storage box 201 is started. The operating speed of the drive pump 206 is adjusted according to the actual treatment needs to adapt to the delivery requirements of different concentrations of the solution. The drive pump 206 smoothly delivers the traditional Chinese medicine solution in the storage box 201 to the ultrasonic generator 207. The ultrasonic generator 207 starts working and generates high-frequency vibrations at a preset frequency, atomizing the traditional Chinese medicine solution delivered inside into tiny particles, preparing for subsequent filtration and inhalation. The atomized traditional Chinese medicine solution is delivered to the rectangular filter box 203 through the gas delivery tube 205. The solution first flows through the pre-filter membrane 209 near the bottom of the filter box 203. The system pre-filters larger particulate impurities in the medication solution, such as microfibers, protein coagulations, and other precipitated particles. After pre-filtration, the nebulized medication solution continues to permeate upwards, passing through a vibrating mesh membrane 208 set parallel to the pre-filtration membrane 209 for secondary fine filtration, further removing micro-impurities. At the same time, the titanium alloy material and nano-coating reduce the adsorption and deposition of sugars, colloids, and proteins in the medication solution on the membrane pore walls, preventing pipe and membrane blockage and ensuring unobstructed nebulization channels. After completing the double filtration, the nebulized medication solution is delivered to the water tank 204 through the air delivery tube 205, allowing the medication solution temperature to be adjusted to a comfortable range suitable for patient inhalation and maintaining temperature stability unaffected by external ambient temperature. A filter screen is installed at the connection between the water tank 204 and the air delivery tube 205 for a third filtration of the nebulized medication solution, further improving the purity of the medication solution and ensuring treatment safety. The inner wall of the gas delivery tube 205 is coated with a hydrophobic coating to prevent the liquid medicine from remaining in the tube and to prevent the mixing of different liquid medicines during use. This ensures the purity and therapeutic effect of the liquid medicine inhaled each time. After temperature regulation and three filtrations, the nebulized liquid medicine is finally delivered to the breathing mask through the gas delivery tube 205. After the patient puts on the breathing mask, he / she can inhale the nebulized traditional Chinese medicine liquid medicine to complete the treatment. Throughout the entire process, the multi-functional display screen of the controller 104 displays the working status of the nebulizer, the remaining liquid medicine, and fault alarm information in real time.
