Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intelligent traditional Chinese medicine vaporization device for children with asthma. Background Technology

[0002] Asthma is one of the most common chronic respiratory diseases in childhood. Traditional Chinese medicine (TCM) has rich experience in the prevention and treatment of asthma, among which TCM aerosol inhalation therapy is a unique external treatment method. This therapy uses a compound decoction or extract of Chinese herbs with effects such as clearing the lungs, relieving asthma, resolving phlegm, and stopping cough. These are converted into fine aerosol particles using an aerosol generator (such as a high-temperature / high-pressure nebulizer or ultrasonic nebulizer), and inhaled through the child's mouth / nose, allowing the active ingredients to act directly on the airway mucosa and even the alveolar tissue. Compared to traditional oral or intravenous administration, aerosol inhalation avoids gastrointestinal absorption and the first-pass effect of the liver, offering significant advantages such as high local drug concentration, rapid onset of action, and fewer systemic adverse reactions.

[0003] When existing TCM vaporization devices are applied to young children with asthma, the following problems exist:

[0004] Firstly, the therapeutic utilization rate is poor, and the medication is difficult to penetrate deep into the narrow airways of children. The core goal of vaporized inhalation therapy is to deliver and adhere the medication to the lesion site in the airway. However, when using existing TCM vaporization devices, the vaporized herbal liquid tends to adhere to the mouth, nose, and pharynx, making it difficult to penetrate deep into the narrow airways of children through the bronchioles. It cannot directly reach the lesion to exert a soothing and bronchodilating effect, and can only act on the superficial areas, resulting in low drug utilization and poor therapeutic effect.

[0005] Secondly, children's respiratory physiology is characterized by small tidal volume and rapid respiratory rate, with their exhalation time typically longer than their inhalation time. Most existing devices operate on a continuous aerosol generation and output mode. During the child's exhalation phase, a large amount of aerosol containing the active pharmaceutical ingredient is directly released into the outside air, failing to penetrate deep into the respiratory tract. This results in significant drug waste, meaning the actual amount of medication exerting its therapeutic effect is far lower than expected, impacting treatment effectiveness. Furthermore, children often experience sudden changes in respiratory rhythm during treatment due to tension, crying, or movement, leading to highly unstable breathing. Continuous high-intensity inhalation therapy can easily cause the child's airway to be irritated by a sudden high concentration of the drug aerosol, triggering severe coughing. Once coughing occurs, it exacerbates the child's discomfort and fear, further reducing their compliance and creating a vicious cycle. Summary of the Invention

[0006] This invention aims to provide an intelligent TCM vaporization device for children with asthma. It utilizes a drug storage component to store and mix TCM liquid, and a vaporization component to vaporize the liquid. The inhalation component includes a mouthpiece and a mouthpiece to facilitate the deep penetration of the vaporized TCM liquid into the child's airway, improving therapeutic efficacy. An intelligent control component adaptively and linearly adjusts the vaporization rate of the TCM liquid according to the child's breathing rhythm, reducing the risk of choking caused by sudden changes in aerosol concentration, and improving the effectiveness, comfort, and safety of vaporization therapy. This invention solves the problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An intelligent TCM vaporization device for children with asthma includes a vaporization component, a drug storage component, a vaporization conduit, an inhalation component, and an intelligent control component. The vaporization component includes a vaporization bottle; the drug storage component includes a storage bottle for storing TCM liquid; the vaporization bottle is connected to a liquid-drawing pump, a power supply unit, a vaporization control unit, and a vaporization generator; a heating chamber is also provided inside the vaporization bottle; the inlet and outlet of the liquid-drawing pump are respectively connected to the storage bottle and the heating chamber; a heating element is provided inside the heating chamber; the inlet and outlet of the vaporization generator are respectively connected to the heating chamber and the vaporization conduit; the power supply unit is electrically connected to and powers the liquid-drawing pump, the vaporization control unit, the heating element, and the vaporization generator; the vaporization control unit is communicatively connected to and controls the operation of the liquid-drawing pump, the heating element, and the vaporization generator; the inhalation component includes a base, a mouthpiece connected to the base, a mouthpiece connected to the mouthpiece, and a vaporization conduit extending from the base to the inhalation component. One end of the gasification generator is connected to the mouthpiece; the intelligent control component includes a linear slide valve, a fixed cylinder, and a wireless communication module. A spring is connected to the bottom of the fixed cylinder, and a slider is connected to the free end of the spring. The slider is connected to a nose-breath linkage plate, and the slider is connected to the control end of the linear slide valve. The slider slides along the axial direction of the fixed cylinder, and the control end of the linear slide valve slides accordingly to adjust the operating state of the linear slide valve. The wireless communication module connects the linear slide valve and the gasification control unit, and the gasification control unit controls the operation of the liquid pump, heating element, and gasification generator according to the operating state of the linear slide valve. When the nose-breath linkage plate moves the slider away from the mouthpiece, the opening of the linear slide valve decreases, and the operating power of the liquid pump, heating element, and gasification generator decreases. When the spring pushes the slider towards the mouthpiece, the opening of the linear slide valve increases, and the operating power of the liquid pump, heating element, and gasification generator increases.

[0009] Furthermore, the liquid pump, power supply unit, vaporization control unit, and vaporization generating device are all located inside the vaporization bottle, and are arranged from bottom to top inside the vaporization bottle. The heating chamber is located between the vaporization control unit and the vaporization generating device.

[0010] Furthermore, the heating element includes a plurality of heating rings, which are evenly arranged inside the heating chamber.

[0011] Furthermore, the liquid storage bottle is detachably connected to the lower side of the vaporization bottle, and a flexible part is provided in the middle of the liquid storage bottle. When the liquid storage bottle is squeezed or stretched along the axial direction, the flexible part undergoes elastic deformation, which is used to improve the mixing uniformity of the internal Chinese medicine liquid.

[0012] Furthermore, the inlet end of the liquid pump is connected to the liquid storage bottle via a flexible tube, the outlet end of the liquid pump is connected to the heating chamber via a liquid guide tube, the outlet end of the liquid guide tube is connected to the inner top wall of the heating chamber, and the outlet end of the liquid guide tube is provided with several side holes.

[0013] Furthermore, the liquid inlet of the gasification generator is connected to the heating chamber via a conduit, and the liquid inlet of the conduit is located below the side hole of the liquid guide pipe; the liquid outlet of the gasification generator is detachably connected to the gasification conduit, and the liquid outlet of the gasification generator is connected to a control valve to control its conduction state.

[0014] Furthermore, the mouthpiece is arc-shaped, and the mouthpiece is located on the inner side of the arc of the mouthpiece, while the nasal breathing linkage plate is located directly above the mouthpiece.

[0015] Furthermore, the mouthpiece is wedge-shaped and frustum-shaped, with the end of the mouthpiece connected to the mouth cover being the larger end and the end away from the mouth cover being the smaller end; the mouthpiece and the mouth cover are connected by a flexible component.

[0016] Furthermore, the mouthpiece and the base, the mouthpiece and the flexible component, and the nasal breathing linkage plate and the slider are all detachably connected, and the mouthpiece, mouthpiece, and flexible component are all made of medical rubber material.

[0017] Furthermore, a handle is connected to the upper side of the vaporization bottle, and a handle is detachably connected to the lower side of the base; the fixed cylinder is provided with a groove that cooperates with the slider, and the slider slides through the groove.

[0018] The principles and beneficial effects of the technical solution are as follows:

[0019] 1. This invention provides an intelligent TCM vaporization device for children with asthma, comprising a vaporization component, a drug storage component, a vaporization conduit, an inhalation component, and an intelligent control component. When using this TCM vaporization device, the herbal liquid is stored in the storage bottle of the drug storage component. The pump draws the liquid into the heating chamber, where it is preheated by the heating element and then enters the vaporization generator to be converted into a medicated aerosol. The aerosol is then delivered along the vaporization conduit to the mouthpiece of the inhalation component for the child to inhale. A purely mechanical respiratory sensing mechanism, consisting of a nasal breathing linkage plate, a slider, a spring, a fixed cylinder, and a linear slide valve, directly utilizes the child's nasal exhalation airflow to drive the nasal breathing linkage plate to produce displacement. This displacement is transmitted through the slider to the linear slide valve, causing an opening change. The operating status of the linear slide valve is then fed back to the vaporization control unit via a wireless communication module. The vaporization control unit then adjusts the operating power of the pump, heating element, and vaporization generator in a coordinated manner, automatically reducing the aerosol output during exhalation and automatically increasing the aerosol output during inhalation, thus achieving dynamic synchronization between the TCM vaporization process and the child's respiratory rhythm. It effectively solves the problems of excessive waste of expiratory phase drugs caused by continuous nebulization in existing devices and high risk of coughing due to lack of respiratory synchronization mechanism, and significantly improves the effective deposition rate of drugs in the deep airways of children and the safety of treatment.

[0020] 2. This invention provides an intelligent TCM vaporization device for children with asthma. The device comprises a nasal breathing linkage plate, a slider, a spring, a fixed cylinder, and a linear valve, forming a purely mechanical respiratory synchronization adjustment mechanism. Compared to existing electronic flow or pressure sensors that detect respiratory status, these sensors require direct or close contact with the child's respiratory tract, posing risks of drift, failure, and cross-infection during long-term use in high-temperature, high-humidity medicated mist environments. In this invention, the nasal breathing linkage plate is positioned directly above the mouthpiece, facing the child's nostrils. When the child exhales, the nasal airflow blows towards the linkage plate, pushing it to move the slider along the fixed cylinder axially away from the mouthpiece. The spring is compressed, and the opening of the linear valve decreases accordingly. When the child inhales, the expiratory airflow disappears, the spring rebounds, pushing the slider back to its original position, and the opening of the linear valve increases. This mechanism utilizes the child's own respiratory airflow as the driving force, requiring no power supply. Its simple and reliable structure fundamentally eliminates the reliability risks associated with electronic sensors. More importantly, the slider displacement is positively correlated with the expiratory flow rate / volume. The linear slide valve produces a continuous, gradual change in opening, allowing the operating power of each functional component to decrease or increase gently, rather than being switched on and off instantaneously. This gentle adjustment method avoids the output shock and response lag caused by sudden opening and closing, ensuring a smooth transition in the delivery of the aerosol, reaching deep into the inner airway of children and improving therapeutic efficacy. It is especially suitable for children's shallow, rapid, and irregular breathing characteristics, reducing the risk of choking caused by sudden changes in aerosol concentration, thus simultaneously improving treatment comfort and safety.

[0021] 3. This invention provides an intelligent TCM vaporization device for children with asthma. A flexible section is located in the middle of the storage bottle, allowing for manual homogenization of the medicinal liquid through elastic deformation. The compound decoctions or extracts of traditional Chinese medicine used in vaporization therapy contain various active ingredients, which are prone to stratification and precipitation after standing. This results in low concentrations and insufficient effective components in the early stages of vaporization, and excessively high concentrations in the later stages, causing discomfort. Most existing devices lack a stirring structure or require an electric stirrer, leading to increased complexity, size, and power consumption. This invention features a flexible section in the middle of the storage bottle. When the operator gently squeezes or stretches the bottle along its axial direction, the flexible section undergoes elastic deformation, causing disturbance and flow in the internal medicinal liquid, thus redistributing the precipitated effective components evenly. This structure achieves homogenization in a minimalist way, eliminating the need for additional motors, stirrers, or other components, without increasing the device's weight or power consumption. Furthermore, the operator can perform mixing operations as needed, offering flexibility and convenience, and effectively ensuring a uniform and stable concentration of the medicinal liquid throughout the vaporization process.

[0022] 4. This invention provides an intelligent TCM vaporization device for children with asthma. Through a multi-sided perforated structure at the outlet of the liquid guide tube and a three-dimensional arrangement of heating rings, a multi-stage drug solution processing path is constructed: "multi-point uniform liquid distribution - three-dimensional thermal field preheating - secondary fine vaporization." A pump delivers the drug solution to the heating chamber via the liquid guide tube. The outlet of the liquid guide tube is located on the inner top wall of the heating chamber and has several side holes. The drug solution is evenly dispersed through these side holes, entering the heating chamber as multiple fine streams or dripping, fully contacting the three-dimensional thermal field formed by the evenly arranged heating rings, achieving rapid and uniform preheating. The preheated drug solution enters the vaporization generator for secondary atomization via a conduit. The inlet of the conduit is located below the side holes, ensuring that only fully preheated drug solution enters the vaporization stage, preventing substandard drug solution from participating in vaporization. This multi-stage processing path ensures suitable temperature and uniform particle size of the output aerosol, improving vaporization efficiency and avoiding irritation of the sensitive airways of children by cold mist.

[0023] 5. This invention provides an intelligent TCM vaporization device for children with asthma. The mouthpiece is wedge-shaped, with the larger end connected to the mouth mask and the smaller end extending into the oral cavity. It conforms to the natural opening shape of a child's mouth, facilitating proper inhalation and forming an effective seal, reducing medication leakage. The mouthpiece and mouth mask are connected by a flexible component, which allows the mouthpiece to self-adaptively deflect within a certain angle range. Even with slight head movements or body movements, the mouthpiece maintains a comfortable fit in the mouth, preventing slippage or gum pain. The mouth mask is arc-shaped, conforming to the natural curvature of a child's face without pressure. The mouth mask, mouthpiece, and flexible component are all made of medical-grade rubber. The components are detachable for easy disassembly, cleaning, and disinfection, ensuring both structural integrity and comfort during inhalation while meeting hygiene requirements in medical settings.

[0024] 6. This invention provides an intelligent TCM vaporization device for children with asthma. A handle is provided on the upper side of the vaporization bottle, making it easy for parents or medical personnel to carry and move the device with one hand. A handle is detachably connected to the lower side of the base, which can be held by parents during treatment to help fix the inhalation component to the child's face, or by the child holding it with both hands. It utilizes the child's grasping reflex and tactile exploration instinct, transforming a treatment scenario that might otherwise trigger resistance into a soothing and holding behavior. This reduces the child's tension and crying from a behavioral and psychological perspective, indirectly improving the cooperation and success rate of treatment. A groove in the fixed cylinder guides and limits the movement of the slider, ensuring the uniformity and stability of the movement of the nasal breathing linkage block / slider / spring, thereby ensuring the functionality of the device.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0035] like Figures 1 to 7 As shown, an intelligent TCM vaporization device for children with asthma includes a vaporization component, a drug storage component, a vaporization conduit 3, an inhalation component 4, and an intelligent control component 7. The vaporization component includes a vaporization bottle 1 with a handle 5 connected to the upper side for easy carrying and movement. The drug storage component includes a liquid storage bottle 2 for storing TCM liquid. The liquid storage bottle 2 is detachably connected to the lower side of the vaporization bottle 1 by threads. A flexible part 8 is provided in the middle of the liquid storage bottle 2. When squeezed or stretched along the axial direction of the liquid storage bottle 2, the flexible part 8 undergoes elastic deformation, causing the internal TCM liquid to turbulently flow, thereby redistributing the effective components of the TCM liquid evenly.

[0036] The inner side of the vaporization cylinder 1 is provided with, from bottom to top, a liquid-drawing pump 9, a power supply unit 10, a vaporization control unit 11, and a vaporization generating device 15. A heating chamber 12 is also provided inside the vaporization cylinder 1, located between the vaporization control unit 11 and the vaporization generating device 15. A heating element is provided inside the heating chamber 12. The power supply unit 10 is electrically connected to and supplies power to the liquid-drawing pump 9, the vaporization control unit 11, the heating element, and the vaporization generating device 15. The vaporization control unit 11 is communicatively connected to and controls the operation of the liquid-drawing pump 9, the heating element, and the vaporization generating device 15. The heating element includes several heating rings 14, which are evenly arranged inside the heating chamber 12 to form a three-dimensional uniform thermal field.

[0037] The inlet of the liquid pump 9 is connected to the storage bottle 2 via a flexible hose, and the outlet of the liquid pump 9 is connected to the heating chamber 12 via a guide pipe 13. The outlet of the guide pipe 13 is connected to the inner top wall of the heating chamber 12, and the outlet of the guide pipe 13 has several side holes. The liquid is evenly dispersed through these side holes and enters the heating chamber 12 in multiple fine streams or by dripping, making full contact with the three-dimensional heat field formed by the heating rings 14 to achieve rapid and uniform preheating. The inlet of the vaporization generator 15 is connected to the heating chamber 12 via a conduit. The inlet of the conduit is located below the side holes of the guide pipe 13 to ensure that only fully preheated liquid enters the vaporization process. The outlet of the vaporization generator 15 is detachably connected to one end of the vaporization conduit 3, and the outlet of the vaporization generator 15 is connected to a control valve 6 to control its conduction status, which is used to control the timing and on / off state of the aerosol output.

[0038] The inhalation assembly 4 includes a base 16, with a handle 19 detachably connected to the underside of the base 16. This handle can be held by parents for support and fixation during treatment, or by the child holding it with both hands. A mouthpiece 17 is connected to the base 16. The mouthpiece 17 is curved to fit the natural curve of a child's face without pressure. A mouthpiece 18 is connected to the mouthpiece 17. The mouthpiece 18 is wedge-shaped, with the end connected to the mouthpiece 17 being the larger end and the end away from the mouthpiece 17 being the smaller end. This conforms to the natural opening shape of a child's mouth, facilitating proper latching and effective seal. A flexible component connects the mouthpiece 18 to the mouthpiece 17, allowing the mouthpiece 18 to self-adapt to a certain angle range. Even with slight head movements or body movements, the mouthpiece 18 maintains a comfortable fit in the mouth. The end of the vaporization conduit 3 away from the vaporization generator 15 is connected to the mouthpiece 18, delivering the medicated aerosol to the child's mouth. The mouthpiece 17 and the base 16 are detachably connected, and the mouthpiece 18 and the flexible component are all made of medical rubber material, which makes them easy to disassemble, clean and disinfect individually.

[0039] The intelligent control component 7 includes a linear slide valve 20, a fixed cylinder 21, and a wireless communication module 25. The valve body of the linear slide valve 20 and the fixed cylinder 21 are connected to the upper side of the base 16. A spring 23 is connected to the bottom of the fixed cylinder 21, and a slider 22 is connected to the free end of the spring 23. The fixed cylinder 21 has a groove that cooperates with the slider 22. The slider 22 slides through the groove and can slide freely along the axial direction of the fixed cylinder 21. The slider 22 is connected to a nasal breathing linkage plate 24, which is located directly above the mouth mask 17, facing the child's nostrils. The nasal breathing linkage plate 24 and the slider 22 are detachably connected for easy disassembly and cleaning. The slider 22 is also connected to the control end of the linear slide valve 20. When the slider 22 slides along the axial direction of the fixed cylinder 21, the control end of the linear slide valve 20 slides accordingly, thereby adjusting the opening of the linear slide valve 20. The wireless communication module 25 connects the linear slide valve 20 and the vaporization control unit 11. The vaporization control unit 11 controls the operating power of the liquid pump 9, the heating ring 14, and the vaporization generator 15 according to the operating status of the linear slide valve 20. Specifically, when the nasal breathing linkage plate 24 drives the slider 22 to move away from the mouthpiece 18, the opening of the linear slide valve 20 decreases, and the operating power of the liquid pump 9, the heating ring 14, and the vaporization generator 15 decreases. When the spring 23 pushes the slider 22 to move closer to the mouthpiece 18, the opening of the linear slide valve 20 increases, and the operating power of the liquid pump 9, the heating ring 14, and the vaporization generator 15 increases.

[0040] The specific implementation process is as follows:

[0041] Before using this intelligent TCM vaporization device, connect the storage bottle 2 to the vaporization bottle 1, and add the prepared TCM liquid to the storage bottle 2. Gently squeeze or stretch the flexible part 8 several times along the axis of the storage bottle 2 to redistribute any potentially precipitated active ingredients in the liquid. Connect both ends of the vaporization conduit 3 to the outlet end and the nozzle 18 of the vaporization generator 15, respectively, and check that all connections are secure. The device uses the power supply unit 10 to supply power to each functional component, and the vaporization control unit 11 controls the heating ring 14 to preheat the heating chamber 12 to the preset temperature range.

[0042] When wearing the device, parents can hold the handle 19 on the lower side of the base 16 to help secure the inhalation component 4 to the child's face. Alternatively, the child can hold the handle 19 with both hands, using the grasping reflex to distract attention and provide a calming effect. Simultaneously, the child can hold the small end of the mouthpiece 18 in their mouth; the wedge-shaped mouthpiece 18 naturally conforms to the child's oral cavity shape, forming an effective seal. The mouth mask 17 fits snugly against the child's face, its curved design matching the natural curvature of the face, without causing significant pressure.

[0043] Next, the vaporization control unit 11 is activated. The liquid pump 9 draws the liquid medicine from the storage bottle 2 through a hose to the liquid guide tube 13. The liquid medicine is evenly dispersed from several side holes at the outlet end of the liquid guide tube 13, entering the heating chamber 12 in multiple fine streams or dripping manner. It comes into full contact with the three-dimensional heat field formed by several evenly arranged heating rings 14, achieving rapid and uniform preheating. The preheated liquid medicine enters the vaporization generator 15 through a conduit. The vaporization generator 15 converts the liquid medicine into a drug-containing aerosol. The aerosol is delivered to the mouthpiece 18 through the control valve 6 and the vaporization conduit 3 for the child to inhale.

[0044] During vaporization therapy, the intelligent control component 7 continuously senses the child's respiratory rhythm and dynamically adjusts the output of the drug mist. When the child exhales, the airflow from the nasal cavity blows towards the nasal breathing linkage plate 24, pushing the nasal breathing linkage plate 24 to drive the slider 22 to slide axially along the fixed cylinder 21 away from the mouthpiece 18. The spring 23 is compressed, and the opening of the linear slide valve 20 decreases accordingly. The wireless communication module 25 transmits the signal of the reduced opening of the linear slide valve 20 to the vaporization control unit 11 in real time. The vaporization control unit 11 then reduces the operating power of the liquid pump 9, the heating ring 14, and the vaporization generator 15, thereby reducing the output of the drug mist. When the child inhales, the exhaled airflow disappears, the spring 23 rebounds, pushing the slider 22 and the nasal breathing linkage plate 24 back to their original positions, and the opening of the linear slide valve 20 increases. The vaporization control unit 11 then restores all functional components to high-power operation, increasing the output of the drug mist.

[0045] During the vaporization therapy, the displacement of slider 22 is positively correlated with the child's expiratory airflow rate, the opening of linear slide valve 20 changes continuously and gradually, and the operating power of each functional component also decreases or increases flexibly, avoiding output shock caused by instantaneous on / off switching. This cycle automatically reduces drug mist waste during exhalation and ensures sufficient drug mist enters the deep respiratory tract during inhalation, achieving dynamic synchronization between the vaporization process of traditional Chinese medicine and the child's respiratory rhythm, thus improving the effective deposition rate of the drug in the deep airways. When the child's breathing rhythm becomes abnormal due to crying or activity, the nasal breathing linkage plate 24 can still follow the airflow changes in real time, producing corresponding displacements. The system continuously maintains flexible adjustment, preventing high-concentration drug mist impacts due to respiratory disturbances and reducing the risk of choking.

[0046] After the vaporization treatment is completed, turn off the power, remove the mouthpiece 18 from the child's mouth, disassemble the liquid storage bottle 2 to pour out the remaining liquid, and disassemble the vaporization tube 3. Remove the mouth mask 17 from the base 16, and remove the mouthpiece 18 and the nasal breathing linkage plate 24 from the flexible part and the slider 22, respectively. Clean and disinfect each part for future use.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
