Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to nebulizer handles and temperature-controlled nebulizer systems. Background Technology

[0002] Nebulization therapy can be used clinically to perform both inhalation therapy and ablation therapy. Inhalation therapy typically uses a nebulizer to disperse medication into tiny droplets or particles, suspending them in a gas stream and delivering them into the respiratory tract and lungs to treat lesions. Ablation therapy generally involves heating a working medium to a predetermined temperature, transferring heat energy to the lesion to achieve ablation. The basic nebulization methods are as follows: a) High-speed gas-liquid mixing, where the high-speed gas disrupts the continuity of the liquid, forming atomized droplets; b) Ultrasonic nebulization, where the high-speed vibration of an ultrasonic plate breaks the liquid into tiny particles; c) Direct nebulization, where centrifugation / pressurization causes the liquid to move at high speed, breaking its continuity and forming small droplets.

[0003] Nebulization in common ablation therapy is usually achieved by heating the medium until it exceeds or approaches the boiling point of the working medium. The inventors found that the nebulization temperature near the boiling point is limited, the tubing is difficult to vent, the heat loss is large, the requirements for consumables are high, and there is a large heat loss during the delivery of the working medium, which limits the development of nebulization therapy.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Reference Appendix Figure 5 To be continued Figure 11 The embodiment shown in this application discloses an atomizing handle 5 connected to an air passage and a liquid passage. The atomizing handle 5 includes a grip body 51 and a temperature control component 52 disposed within the grip body 51. The temperature control component 52 includes:

[0040] Heating base 521 is fixedly mounted on atomizing handle 5;

[0041] Heating tube 522 is fixedly installed inside heating base 521. Heating tube 522 is hollow inside and one end is connected to liquid pipeline, and the other end is connected to liquid delivery port 5221. Liquid delivery port 5221 is provided on the outer peripheral surface of grip body 51.

[0042] The turbulence-disrupting component 523 is located inside the heating tube 522 and occupies the central space of the heating tube 522. The gap between the turbulence-disrupting component 523 and the heating tube 522 is the heating path 524. The working medium in the liquid pipeline adheres to the inner wall of the heating tube 522 and penetrates the heating tube 522 via the heating path 524.

[0043] The heating element 522 provides thermal compensation for the working medium, enabling temperature control at the handle end. This improves temperature control accuracy and responsiveness, preventing delays caused by long-distance transportation. The baffle assembly 523 enhances the efficiency of the heating element 522, controlling the overall size of the atomizing handle 5 while maintaining the same heating performance, thus improving the user experience. (The attached text is incomplete and requires further context.) Figure 11 The heating path 524 shown is only one direction of operation; the actual direction of operation of the working medium is not limited to the direction indicated by the arrow.

[0044] In a specific implementation, referring to one embodiment, the turbulence assembly 523 includes a spacer 5231, which is a rod extending along the heating tube 522, with the axis of the heating tube 522 located inside the spacer 5231. In the accompanying drawings, the heating tube 522 has a cylindrical structure, and the spacer 5231 has a rod-like structure. The ratio between the outer diameter of the spacer 5231 and the inner diameter of the heating tube 522 ranges from 0.4 to 0.98. Independently, the turbulence assembly 523 includes a turbulence member 5232, which is disposed on the outer peripheral surface of the spacer 5231 and extends axially along the spacer 5231. The gap between the turbulence member 5232 and the inner wall of the heating tube 522 forms the heating path 524. The turbulence member 5232 can change the movement path of the working medium, thereby increasing the heat exchange area without changing the overall size of the heating tube 522. In terms of details, the baffle 5232 is spirally arranged around the outer peripheral surface of the occupier 5231, with the inner edge of the baffle 5232 abutting against the outer peripheral surface of the occupier 5231, and the outer edge of the baffle 5232 abutting against the inner peripheral surface of the heating tube 522. This abutting arrangement can improve heat exchange efficiency while avoiding gaps between components, thus preventing abnormal noises from the atomizing handle 5 during operation.

[0045] Referring to one embodiment, the two axial ends of the occupant 5231 are mating ends 5233, the radial dimension of which is smaller than the radial dimension of the middle part of the occupant 5231. The proximal side of the baffle 5232 extends at least to the outer periphery of the mating end 5233 on the proximal side of the occupant 5231. The gap between the baffle 5232 and the mating end 5233 on the proximal side of the occupant 5231 is the heating inlet 5241 of the heating path 524. The mating ends 5233 can further constrain the installation accuracy of the occupant 5231, thereby improving the dimensional accuracy of the heating path 524 and improving the heat exchange effect. The heating inlet 5241 mentioned above can also be set on the distal side of the occupant 5231 to form a heating outlet, further extending the heat exchange path.

[0046] In addition to the temperature control settings for the liquid path mentioned above, you can also refer to the appendix. Figure 12 As shown, the heating base 521 is hollow inside, forming a heat exchange chamber 5211. The heating tube 522 passes through the heat exchange chamber 5211, allowing heat exchange between the internal space of the heat exchange chamber 5211 and the outer surface of the heating tube 522. The heat exchange chamber 5211 fully utilizes the heating area of ​​the heating tube 522, providing more space for heat exchange. In detail, the heat exchange chamber 5211 is sealed and has a heat exchange inlet 5212 and a heat exchange outlet 5213, one of which is connected to a gas pipeline, and the other to a gas inlet. Heating both the gas and liquid phases through the same heating tube 522 ensures heating temperature while controlling the overall number and volume of components, avoiding unnecessary heat loss. (See attached...) Figure 13 In the illustrated embodiment, the heat exchange chamber 5211 is also connected to a first thermocouple mounting port 5216 and a second thermocouple mounting port 5217. Thermocouples located at both ends of the heating tube 522 can accurately measure the heating effect of the heating tube 522 and evaluate the heating capacity reserve of the heating tube 522 based on the measurement data, thereby providing structural support for precise temperature control. In one embodiment, the temperature control atomization system adjusts the flow rate of the liquid phase medium and / or gas phase medium according to the remaining heating capacity reserve of the heating tube 522. The pipeline of the heating tube 522 is connected to the outside through heating element connection ports 5214 and 5215. This arrangement can avoid unnecessary heat exchange between the heat exchange chamber and the external space due to the pipeline arrangement, and the heat exchange chamber can ensure a stable temperature, thereby achieving a better heat exchange effect in the gas path.

[0047] In this embodiment, the gas and liquid phases only exchange heat near the heating tube 522 while remaining isolated from each other, thus preventing the premature mixing of media with different pressures and properties from affecting subsequent atomization. Structurally, the heating tube 522 is sealed, with the working medium in the liquid path exchanging heat with the inner surface of the heating tube 522, and the working medium in the gas path exchanging heat with the outer surface of the heating tube 522.

[0048] In practical use, the gas and the heated liquid eventually converge at the distal end of the interventional catheter and achieve atomization through the interventional catheter and the mixing structure within the catheter. Before the gas and liquid converge, the gas needs to be preheated. In this embodiment, the inner cavity of the heating tube can heat the liquid, and the outer cavity can preheat the gas, thereby reducing the problem of the gas carrying away the liquid temperature during the process before the liquid and gas mix.

[0049] Based on the above description, this application discloses a temperature-controlled nebulization system, including a nebulization therapy device for providing liquid and gaseous media, a nebulizer handle 5, and an interventional catheter. The nebulization therapy device includes a reservoir 1 for containing, controlling the temperature of, and delivering the working medium, and an output component 2 for establishing positive or negative pressure within the reservoir 1. The output component 2 delivers the working medium in the reservoir 1 that meets preset conditions to the nebulizer handle 5.

[0050] The atomizing handle 5 includes a grip body 51 and a temperature control component 52 disposed within the grip body 51. The temperature control component 52 independently processes the liquid and gaseous media to a preset temperature and delivers them to the distal end of the interventional catheter.

[0051] The distal end of the interventional catheter is equipped with a mixing structure, within which liquid and gaseous media meeting preset conditions are mixed and atomized. The proximal end of the interventional catheter is connected to the gas and liquid channels (i.e., the liquid delivery port and gas delivery port) of the nebulizer handle, delivering the corresponding liquid and gaseous media to its distal end for atomization.

[0052] Regarding the implementation of the treatment equipment, participants Figure 1 To be continued Figure 9 As shown, the nebulizer therapy device includes:

[0053] The liquid storage tank 1 is used to contain the working medium and includes a vertically arranged cylinder 11 and a heating plate 12 that closes the bottom of the cylinder 11. The liquid storage tank 1 includes a controllable liquid inlet passage 13 and a liquid outlet passage 14, wherein at least the liquid outlet passage 14 is in communication with the bottom space of the cylinder 11 via the heating plate 12.

[0054] The output component 2 includes a piston slidably disposed inside the cylinder 11 of the storage tank 1 and a drive component for driving the piston to move. The piston enters through the top of the cylinder 11, and the top of the cylinder 11 is provided with a first seal 111. The piston slides in cooperation with the first seal 111. The piston has a standby position that is out of the cylinder 11 and a relative working stroke. During the working stroke, the piston occupies the space inside the cylinder 11 to pressurize the working medium.

[0055] Functional component 3 includes a controllable venting passage 31 and an air pump connected to the venting passage 31, the venting passage 31 being connected to the upper space of the cylinder 11.

[0056] During the liquid inlet process, the nebulizer therapy device uses the piston to exit the cylinder 11 and / or the functional component 3 to achieve negative pressure liquid inlet in the storage tank 1;

[0057] During the evacuation process, the nebulizer enters the cylinder 11 and / or the functional component 3 via a piston to achieve the evacuation of the liquid storage tank 1.

[0058] The storage tank 1 provides a space that integrates storage, temperature control, and pressurization. For storage, the open cylindrical body 11 provides the structural basis for subsequent setup; for pressurization, the movement of a piston establishes negative and positive pressure within the storage tank 1; for temperature control, the heating plate 12 meets heating requirements, while the cylindrical body 11 and piston of the storage tank 1 meet heat dissipation requirements. The technical solution in this application also includes a functional component 3, providing a more convenient operating method within the storage tank 1. Overall, the technical solution disclosed in this application effectively overcomes the problems of working medium temperature control and evacuation procedures through structural optimization of the nebulization therapy device, providing a structural basis for flexible control of the working medium temperature and improved nebulization adaptability. Compared to traditional steam ablation systems, which carry large amounts of energy, are fast, have a wide range, are not suitable for small-area ablation, and cause some damage to native tissue, this solution effectively improves adaptability. In practical use, the working medium includes purified water or physiological saline. In one embodiment, the working medium carries a drug. In terms of drug delivery, the working medium is a solution containing the drug or a non-dissolved mixture.

[0059] In the specific configuration of the storage tank 1, referring to the embodiment shown in the attached drawings, the cylinder 11 of the storage tank 1 is an open cylinder at both ends. The piston enters the interior of the cylinder 11 through the upper opening and is sealed by the first sealing member 111. The heating plate 12 seals the lower opening of the cylinder 11, and the heating surface is exposed inside the cylinder 11. By sealing the cylinder 11 with the piston and the heating plate 12, a compact layout of the device can be achieved, and the internal space of the storage tank 1 is more fully exposed to the components that need to perform functions. For example, the heating plate 12 includes a plate seat 121 located on the outer periphery and a heating component 122 located in the plate seat 121. The plate seat 121 is sealed to the lower opening of the cylinder 11 by the second sealing member 112. An annular gap 123 is provided between the second sealing member 112 and the heating component 122, and the liquid outlet passage 14 passes through the annular gap 123. The annular gap 123 improves both the compactness of the layout and the heating efficiency of the heating plate 12, ensuring that the liquid flowing in the outlet passage 14 always passes near the heating element 122, thereby improving heating efficiency and temperature control accuracy. For the same reason, it is important to avoid the interfaces of the inlet passage 13 and the outlet passage 14 on the heating plate 12 being too close, which could cause a short circuit in the working medium flow path. Therefore, in one embodiment, the inlet passage 13 is arranged opposite to the outlet passage 14 via the annular gap 123. In the actual structure, the line connecting the interfaces of the liquid passage and the outlet passage 14 on the heating plate 12 passes through the center of the heating element 122 of the heating plate 12.

[0060] Regarding the setup of the pathways, please refer to the appendix. Figure 4 In the illustrated embodiment, the storage tank 1 includes a controllable waste liquid passage 15, one end of which is disposed on the heating plate 12 or the outlet passage 14, and the other end is connected to the manifold 4. The waste liquid passage 15 is mainly used to handle excess working medium and clean the pipeline. The storage tank 1 includes a controllable safety passage 16, one end of which is connected to the inside of the cylinder 11, and the other end is connected to the manifold 4. The safety passage 16 is used to provide mechanical / control system-independent safety assurance, generally achieved through an independent pressure valve, or through an independently operating control device 9114. In terms of overall flow direction, the nebulizer includes a main inlet and a main outlet, and the manifold 4 is connected to the main outlet. The manifold 4 can collect gas and liquid, avoiding complex pipeline setup, while providing buffer space to ensure the stability of the internal flow.

[0061] The liquid storage tank 1, while storing and heating the liquid, also has a heat dissipation function. If the heat dissipation is too weak, higher heating accuracy is required; if the heat dissipation is too strong, it increases the burden on the heating device and generates heat output to surrounding components. In this embodiment, a heat-insulating seal 1111 is pressed onto the first seal 111, and the piston passes through the heat-insulating seal 1111 and the first seal 111 sequentially as it moves towards the cylinder 11. The heat-insulating seal 1111 effectively prevents heat transfer from the cylinder 11 of the liquid storage tank 1 and the working medium inside the heat storage tank to the relevant components of the output assembly 2, thereby improving temperature control accuracy.

[0062] For the specific settings of output component 2, please refer to the appendix. Figure 7 To be continued Figure 6 In the illustrated embodiment, the driving component includes:

[0063] Drive motor 221, drive motor 221 is equipped with a transmission screw;

[0064] The drive slider 223 is fixedly mounted on the piston and screwed to the drive screw.

[0065] The piston is a cylindrical shape with an open top and its upper end is connected to the drive slider 223. The transmission screw extends into the interior of the piston.

[0066] The drive slider 223 converts the rotation of the drive motor 221 and the transmission screw into linear motion and provides guidance, thereby achieving stable and high-precision piston movement. In this implementation, the drive slider 223 can achieve linear motion via the drive slide rail 2231.

[0067] In controlling the motion stroke, referring to one embodiment, the drive slider 223 is provided with a trigger 2232, and the side of the drive slide rail 2231 is provided with a first position sensor 2233 and a second position sensor 2234 that respond to the trigger 2232. The drive motor 221 is controlled by the first position sensor 2233 and the second position sensor 2234.

[0068] To improve the rotational accuracy and axial concentricity of the transmission screw, in one embodiment, a sliding engagement component is provided on the side of the transmission screw away from the drive motor 221. The inner ring of the sliding engagement component rotates with the transmission screw, and its outer circumference slides with the inner wall of the piston. In implementation, the sliding engagement component can be a combined structure, comprising a thrust bearing for the inner ring and a sliding wear-resistant ring for the outer ring. This arrangement reduces the precision requirements of the components, and the use of standard parts reduces production and assembly pressure. Similarly, to improve the axial stability of the piston during movement, in one embodiment, an annular wear-resistant ring is provided at the end of the piston away from the drive slider 223. The wear-resistant ring slides with the inner wall of the cylinder 11. The wear-resistant ring is arranged circumferentially around the piston and has at least one release gap. The wear-resistant ring extends axially along the piston, and the ratio between its axial length and the piston diameter ranges from 0.1 to 0.7.

[0069] As can be easily understood from the above, the piston is a single-end closed cylindrical shape. In terms of size and structure, referring to one embodiment, the ratio between the piston's outer diameter and its inner diameter ranges from 1.5 to 3; the ratio between the piston's outer diameter and the outer diameter of the drive screw ranges from 1.8 to 5. In terms of overall layout, referring to one embodiment, the cylinder 11, piston, and drive screw are arranged vertically, and the drive motor 221 is located above the drive screw and the two are connected to each other through a coupling.

[0070] Regarding the details of the configuration of functional component 3, referring to one embodiment, functional component 3 includes a gas-liquid separator 33. The top of the gas-liquid separator 33 is connected to an air pump, and the middle or bottom is connected to an evacuation passage 31. The gas-liquid separator 33 can realize the gas-liquid separation of the fluid discharged from the storage tank 1 and provides a buffer space, thereby providing a structural basis for precise control.

[0071] For example, in the configuration of the venting passage 31, according to one embodiment, a liquid sensor 311 is provided on the venting passage 31, and the opening and closing of the venting passage 31 and / or the air pump are controlled by the liquid sensor 311. The main function of the liquid sensor 311 is to determine the end point of the venting process. When the liquid sensor 311 is triggered during the venting process, it means that the venting has been completed. In the actual structure, according to one embodiment, the venting passage 31, from the liquid storage tank 1 to the gas-liquid separator 33, includes a venting control valve 312 and a liquid sensor 311 that control the venting passage 31. The advantage of setting the venting control valve 312 before the liquid sensor 311 is that it can ensure the accuracy of the determination of the end point of the venting process. When the liquid sensor 311 is triggered, the possibility that there is still air before the venting control valve 312 is greatly reduced, avoiding the risk of incomplete venting.

[0072] In one embodiment, the gas-liquid separator 33 is equipped with a liquid level sensor, and the air pump is controlled by the liquid level sensor. The liquid level sensor is located on the outside of the gas-liquid separator 33 and is vertically lower than the connection point between the drain passage 31 and the gas-liquid separator 33. This arrangement improves the stability of the liquid level sensor and prevents it from being falsely triggered by disturbed fluid. Structurally, the liquid level sensor is capacitive. In addition to the physical liquid level sensor, the liquid level sensing in this application can also be obtained by the control device based on signal processing from other sensors. For example, in one embodiment, the functional component 3 includes a bubble sensor, which can detect bubbles in the gas-liquid separator. The bubble sensor can determine whether the piston pushes the gas or liquid level in the storage tank into the gas-liquid separator. Therefore, based on the data from the bubble sensor, especially the continuous data from the bubble sensor, the control device can determine whether the piston and the liquid in the storage tank are in complete contact. Once the bubble sensor stops receiving bubble signals, it is assumed that the piston is in complete contact with the liquid inside the storage tank (i.e., the bubbles are considered to have been displaced). At this point, the control device can calculate the current liquid level in the storage tank based on the operating status of the drive motor, and thus control the liquid level. In this embodiment, the liquid level of the working medium is confirmed through the coordinated operation of the bubble sensor and the drive motor; the control device achieves liquid level control function without a direct liquid level sensor.

[0073] The liquid level sensor 331 on the gas-liquid separator 33, in addition to detecting the liquid level inside the separator 33, also protects the air pump, preventing it from drawing liquid from the separator 33 and causing unnecessary malfunctions. Similarly, in one embodiment, a liquid-proof device is provided at the top of the gas-liquid separator 33, and the air pump is connected to this device. The liquid-proof device effectively provides stability for the air pump. Specifically, the liquid-proof device includes an air passage communicating with the interior of the gas-liquid separator 33 and a liquid-blocking baffle positioned between the air passage opening and the drain passage 31. The liquid-blocking baffle is inclined and faces the bottom of the gas-liquid separator 33. Regarding the passage configuration, a controllable drain passage 333 is provided at the bottom of the gas-liquid separator 33, and the other end of the drain passage 333 is connected to the manifold 4.

[0074] In addition to the purging process mentioned above, functional component 3 can provide richer practical functions. For example, in one embodiment, the air pump is a bidirectional air pump, and its working state relative to the purging passage 31 is switched via an air path switching valve. The air path switching valve can switch the air pump to provide positive or negative pressure to the purging passage 31. During purging, the air pump can establish negative pressure on the gas-liquid separator 33, the purging passage 31, the liquid storage tank 1, and the corresponding pipelines, thereby drawing liquid into the corresponding location. During purging, the air pump can establish positive pressure on the gas-liquid separator 33, the purging passage 31, the liquid storage tank 1, and the corresponding pipelines, thereby blowing fluid out of the corresponding location. This setup, through the scientific arrangement of simple components, effectively improves the richness of equipment functions without significantly increasing the equipment burden, enhances the user experience, and provides a structural basis for more functional settings.

[0075] In terms of overall layout, refer to the appendix. Figure 1 and attached Figure 10 In the illustrated embodiment, the nebulizer includes an intersecting main frame 91 and a vertical frame 92 mounted on the main frame 91. The main frame 91 includes an upper operating area 911 and a lower tubing area 912. The vertical frame 92 is located within the operating area 911, and the output components are mounted on the vertical frame 92. Further, the vertical frame 92 divides the operating area 911 into a mechanical area and an electrical area. The electrical area contains a control circuit 9113 located behind the main frame 91 and a control device 9114 located in front of the main frame 91. The liquid outlet passage 14 includes a liquid outlet connection port 141 for connection with consumables. The liquid outlet connection port 141 is located in the tubing area 912 and below the control device 9114. A main liquid inlet and a main liquid outlet are located at the rear of the vertical frame 92. The liquid inlet passage 13 extends around one side of the main frame 91 to the tubing area 912. The manifold 4 is located on one side of the main frame 91 and is lower than the main frame 91. The corresponding pipes of the pipeline area 912 are connected to the main outlet via the manifold 4. The main frame 91 is provided with a through hole 913. The cylinder 11 of the storage tank 1 is disposed in the through hole 913, and the heating plate 12 is disposed in the pipeline area 912. The through hole 913 is located in front of the vertical frame 92.

[0076] The above setup divides the space into regular areas through the main frame 91 and the vertical frame 92 mounted on the main frame 91. Each component cooperates with each other in its corresponding area. The equipment as a whole works independently while maintaining a compact layout, making it less prone to interference. This improves stability and provides a good foundation for the overall appearance design of the product.

[0077] It is not difficult to understand that this application also discloses a control method for a nebulizer, used to control the nebulizer to perform preset operations on the working medium. The nebulizer includes a heatable reservoir 1, a piston capable of applying pressure to the reservoir 1, and an air pump capable of establishing negative or positive pressure within the reservoir 1. The control method includes:

[0078] During the liquid inlet process, negative pressure liquid inlet is achieved in the liquid storage tank 1 by piston withdrawal and / or air pump operation;

[0079] The evacuation process is achieved by a piston entering the liquid storage tank 1 and / or by an air pump working to empty the liquid storage tank 1.

[0080] During the temperature control process, the working medium is adjusted to the preset temperature by heating the liquid storage tank 1;

[0081] During the delivery process, the piston enters the storage tank 1 and / or the air pump works to pressurize the storage tank 1 to the preset pressure. Under the preset conditions, the working medium leaves through the liquid outlet passage 14 of the storage tank 1 and achieves the corresponding function. In subsequent processes, the nebulizer maintains the pressure value of the working medium by entering the storage tank 1 and / or the air pump.

[0082] The above processes do not have a fixed execution order. In actual implementation, the order of the steps may be adjusted, and a certain step may be performed multiple times. The working process is illustrated below with the example of the nebulizer treatment device mentioned above.

[0083] During the liquid inlet process, the liquid inlet solenoid valve 131 on the liquid inlet passage 13 is opened, and the drive motor 221 reverses to drive the transmission screw to rotate, causing the drive slider 223 to drive the piston to move upward, creating a negative pressure in the liquid storage tank 1. The working medium enters the liquid storage tank 1 through the liquid inlet solenoid valve 131 due to the negative pressure.

[0084] During this process, the air pump can also work in conjunction to improve the liquid inlet efficiency. In one embodiment, the operation of the air pump 32 and the movement of the piston 21 work synchronously and collaboratively. For example, as the piston 21 moves upward, the air pump 32 simultaneously establishes a negative pressure within the storage tank 1. In another embodiment, the operation of the air pump 32 and the movement of the piston 21 work in stages. For example, before the liquid inlet solenoid valve 131 opens, the air pump 32 first establishes a negative pressure within the storage tank 1, then opens the liquid inlet solenoid valve 131 and drives the piston 21 to move upward to achieve liquid inlet. Similarly, during the movement of the piston 21, the air pump 32 can be configured to remain continuously operating, or it can be configured to stop operating before the piston 21 begins to move and disconnect the connection between the air pump 32 and the storage tank 1 via a venting control valve.

[0085] During the venting process, the venting solenoid valve in the venting passage 31 is opened, and the drive motor 221 rotates forward to drive the transmission screw to rotate, causing the drive slider 223 to drive the piston to move downward, so that the air in the upper part of the liquid storage tank 1 is discharged through the venting solenoid valve. When the liquid sensor 311 detects the liquid, it is determined that the air has been vented, and the venting solenoid valve and drive motor 221 are closed.

[0086] In another embodiment, the venting process is different. The venting solenoid valve in the venting passage 31 is opened, and the drive motor 221 rotates forward, driving the transmission screw 222 to rotate, causing the drive slider 223 to drive the piston 21 to move downward, so that the air in the upper part of the storage tank 1 is discharged through the venting solenoid valve. When the bubble sensor does not continuously receive bubble signals, it is determined that the air has been vented, and the venting solenoid valve and drive motor 221 are closed; and the liquid level in the storage tank 1 is calculated based on the current operating data of the drive motor 221.

[0087] During this process, the air pump can also work together to improve the evacuation efficiency. Especially when the temperature of the working medium in the storage tank 1 is high, the negative pressure caused by the piston moving upward may lead to increased vaporization of the working medium, resulting in insufficient negative pressure and other working conditions.

[0088] During temperature control, the heating plate 12 is activated to heat the liquid in the storage tank 1, and the temperature is fed back in real time by the temperature sensor 124. The temperature is kept constant by software control.

[0089] During the delivery process: the outlet solenoid valve 142 in the outlet passage 14 is opened, the drive motor 221 rotates forward, driving the transmission screw to rotate, causing the drive slider 223 to drive the piston downward. The working medium passes through the outlet solenoid valve 142 at a constant flow rate and / or pressure, enters the consumable through the outlet connection port 141, and performs the corresponding operation.

[0090] As mentioned above, functional component 3 can also achieve richer functions. Referring to one embodiment, the control method of the nebulizer therapy device further includes:

[0091] The purging process involves using an air pump to empty the liquid storage tank 1 and its corresponding passageway.

[0092] In the waste liquid process, the working medium enters the storage tank 1 via a piston and / or the air pump operates to achieve the working medium entering the manifold 4 via the waste liquid passage 15 of the storage tank 1.

[0093] Similarly, the above processes do not limit the execution order of each process. In actual implementation, the order of each step may be adjusted, and a certain step may be performed multiple times or independently. The working process is illustrated below with the example of the nebulizer treatment device mentioned above.

[0094] During the purging process, for example when the nebulizer is being transported or has been completely used, it is necessary to empty all the remaining liquid in the pipes and the storage tank 1. The gas-liquid separator 33 can be pressurized. When the venting solenoid valve is opened, positive pressure is introduced into the storage tank 1. Then, by opening and closing other solenoid valves, all the remaining liquid can be discharged.

[0095] During the waste liquid discharge process, the waste liquid solenoid valve 151 in the waste liquid passage 15 opens, the drive motor 221 rotates forward, driving the transmission screw to rotate, causing the drive slider 223 to drive the piston downward, thus discharging the working medium from the storage tank 1. During this process, an air pump can also be used to improve the waste liquid discharge efficiency, especially for waste liquid in the pipeline. With the assistance of the air pump, repeated flushing operations can be effectively avoided.

[0096] Similar to the liquid inlet process, the operation of the air pump 32 and the movement of the piston 21 during the purging and waste liquid processes can also be configured to work synchronously or in stages. In synchronous operation, as the piston 21 moves downwards, the air pump 32 simultaneously establishes positive pressure within the storage tank 1. In staged operation, the waste liquid solenoid valve 151 is opened, driving the piston 21 downwards to discharge the working medium from the storage tank. When the piston reaches its lower dead center, the air pump 32 operates to establish positive pressure within the storage tank 1 to discharge the working medium from the pipeline. During both processes, the connection between the air pump 32 and the storage tank 1 can be disconnected via the venting control valve.

[0097] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0098] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
