Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to temperature-controllable atomization treatment equipment and an atomization system. Background Art

[0002] Nebulization therapy can be used clinically to achieve inhalation therapy and ablation therapy. Inhalation therapy generally uses a nebulizer to disperse the drug into tiny droplets or particles, suspending them in the gas and entering the respiratory tract and lungs to treat the lesions. Ablation therapy generally achieves ablation by heating the working medium to a predetermined temperature, generating thermal energy transfer to the lesions. In terms of atomization methods, the following methods are basically used: a. High-speed gas is mixed with liquid, and the continuity of the liquid is interrupted by high-speed gas to form atomized droplets; b. Ultrasonic atomization, through the high-speed vibration of the ultrasonic plate, the liquid is shattered to produce tiny particles; c. Direct atomization, through centrifugation / pressurization, the liquid is moved at high speed, thereby breaking the continuity and forming small droplets.

[0003] Atomization in common ablation treatments is generally achieved by heating the working medium to a temperature exceeding or approaching its boiling point.

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be an intermediate component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be an intermediate component.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] With reference to the accompanying drawings, the present application discloses a temperature-controllable atomization treatment device, comprising a liquid storage tank 1 for receiving, temperature-controlling, and delivering a working medium, and an output component 2 for establishing positive or negative pressure in the liquid storage tank 1;

[0053] The liquid storage tank 1 includes a controllable liquid inlet passage 13, a liquid outlet passage 14 and a cylinder 11, and the top of the cylinder 11 is open;

[0054] The output assembly 2 includes a piston 21 slidably disposed in the cylinder 11 and a drive assembly 22 for driving the piston 21 to move. The piston 21 enters through the top of the cylinder 11 and is sealed with the cylinder 11.

[0055] The atomization treatment device is provided with a heat dissipation system and a heating system that counteract each other to ensure the temperature of the working medium. The heat dissipation system includes a cylinder 11 and a piston 21. The outer surface of the cylinder 11 is thermally coupled to the external environment. The piston 21 is divided into a preparation section located on the outer part of the cylinder 11 and an opposite working section. At least the outer surface of the preparation section is coupled to the external environment.

[0056] The cylinder 11 and the piston 21 are both made of heat-conducting material; the heating system includes a heating disk 12, which is only arranged at the bottom of the cylinder 11, and the heating surface of the heating disk 12 is exposed to the interior of the cylinder 11.

[0057] In existing technical solutions, liquid temperature control is achieved solely through heating. Common working media have large specific heat capacities and temperature differences at different locations. Simply increasing the heating power can lead to problems such as overheating, low temperature control accuracy, and the need for frequent starts and stops. This embodiment optimizes the component structure to create a counterbalancing relationship between the heat dissipation system and the heating system, thereby improving temperature control accuracy.

[0058] In terms of specific materials, the piston 21 and the cylinder 11 are made of metal and are thermally coupled by heat exchange between their own materials and the external environment. The piston and the cylinder have a large surface area in space, and good heat dissipation effect can be achieved through heat exchange.

[0059] From another perspective, atomization therapy equipment includes:

[0060] The liquid storage tank 1 is used to store the working medium and includes a vertically arranged cylinder 11 and a heating plate 12 that seals 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 connected to the bottom space of the cylinder 11 through the heating plate 12;

[0061] The output assembly 2 includes a piston 21 slidably disposed within the cylinder 11 of the liquid storage tank 1 and a drive assembly 22 for driving the piston 21 to move. The piston 21 enters through the top of the cylinder 11. The top of the cylinder 11 is provided with a first seal 111, and the piston 21 slidably engages with the first seal 111. The piston 21 has a standby position in which it exits the cylinder 11 and a relative working stroke. During the working stroke, the piston 21 occupies space within the cylinder 11 to increase the pressure of the working medium.

[0062] Functional component 3, including a controllable emptying passage 31 and an air pump 32 connected to the emptying passage 31, the emptying passage 31 is connected to the upper space of the cylinder 11;

[0063] During the liquid filling process, the atomization treatment device operates by withdrawing the piston 21 from the cylinder 11 and / or the functional component 3 to achieve negative pressure liquid filling in the liquid storage tank 1;

[0064] During the emptying process, the atomization treatment device enters the cylinder 11 and / or the functional component 3 through the piston 21 to work to empty the liquid storage tank 1.

[0065] The liquid reservoir 1 provides a space that can meet the three-in-one requirements of liquid storage, temperature control, and pressurization. Regarding liquid storage, the upper and lower open cylinder 11 provides the structural foundation for subsequent configurations. Regarding pressurization, the movement of the piston 21 creates negative and positive pressure within the liquid reservoir 1. Regarding temperature control, the heating plate 12 provides heating, while the cylinder 11 and piston 21 of the liquid reservoir 1 provide heat dissipation. The technical solution disclosed in this application also incorporates a functional component 3, which provides more convenient operation within the liquid reservoir 1. Overall, the technical solution disclosed in this application effectively overcomes the challenges of working medium temperature control and emptying procedures through structural optimization of the atomization therapy device, providing a structural foundation for flexible control of the working medium temperature and improving atomization adaptability. Compared to traditional steam ablation systems, which carry high energy, high speed, and a wide range, are not suitable for small-scale ablation, and may cause some damage to native tissue, this system effectively improves adaptability. In actual use, the working medium comprises purified water or saline. In one embodiment, the working medium contains a drug. In terms of drug loading, the working medium is a drug-loaded solution or a non-dissolving mixed system.

[0066] Regarding the specific configuration of the liquid storage tank 1, referring to the embodiment shown in the accompanying drawings, the barrel 11 of the liquid storage tank 1 is a cylindrical body that is open at the top and bottom. The piston 21 enters the interior of the barrel 11 through the upper opening and is sealed by a first sealing member 111. The heating disc 12 seals the lower opening of the barrel 11 and the heating surface is exposed to the interior of the barrel 11. Sealing the barrel 11 by the piston 21 and the heating disc 12 enables a compact layout of the equipment, exposing the internal space of the liquid storage tank 1 to functional components that require application. For example, the heating disc 12 includes a disc seat 121 located on the periphery and a heating component 122 located within the disc seat 121. The disc seat 121 is sealed to the lower opening of the barrel 11 by a second sealing member 112. An annular gap 123 is provided between the second sealing member 112 and the heating component 122. The liquid outlet passage 14 passes through the annular gap 123. The annular gap 123 can not only improve the compactness of the layout, but also improve the heating efficiency of the heating disk 12, ensuring that the liquid flowing in the liquid outlet passage 14 will definitely flow near the heating component 122, thereby improving the heating efficiency and temperature control accuracy. For the same reason, it should be avoided that the interfaces of the liquid inlet passage 13 and the liquid outlet passage 14 on the heating disk 12 are too close to each other, so as to avoid short-circuiting the working medium flow path. Therefore, referring to one embodiment, the liquid inlet passage 13 is arranged through the annular gap 123 and opposite to the liquid outlet passage 14. In the actual structure, the line connecting the interfaces of the liquid passage and the liquid outlet passage 14 on the heating disk 12 passes through the center of the heating component 122 of the heating disk 12.

[0067] For the setting of the passage, please refer to the attached Figure 6 In the illustrated embodiment, the liquid storage tank 1 includes a controllable waste liquid passage 15, one end of which is arranged on the heating plate 12 or the liquid outlet passage 14, and the other end is connected to the bus 4. The waste liquid passage 15 is mainly used to achieve the treatment of excess working medium and the cleaning of the pipeline. The liquid storage tank 1 includes a controllable safety passage 16, one end of which is connected to the interior of the cylinder 11, and the other end is connected to the bus 4. The safety passage 16 is used to provide a mechanical / independent safety guarantee from the control system, which is generally achieved through an independent pressure valve, and can also be achieved through an independently operated control device 9114. In the overall flow direction, the nebulizer treatment device includes a total liquid inlet 41 and a total liquid outlet 42, and the bus 4 is connected to the total liquid outlet 42. The bus 4 can collect gas and liquid, avoid the complex setting of the pipeline, and at the same time provide a buffer space to ensure the stability of the internal fluid.

[0068] The liquid storage tank 1 has the actual effect of heat dissipation while storing liquid and heating. When the heat dissipation effect is too weak, higher requirements will be placed on the heating accuracy; when the heat dissipation effect is too strong, it will increase the burden on the heating device and generate heat output to the surrounding components. In this embodiment, a heat-insulating seal 1111 is pressed onto the first seal 111, and the piston 21 passes through the heat-insulating seal 1111 and the first seal 111 in sequence during the movement toward the cylinder 11. The heat-insulating seal 1111 here can effectively prevent the cylinder 11 of the liquid storage tank 1 and the working medium in the heat storage tank from transferring heat to the relevant components of the output assembly 2, thereby improving the temperature control accuracy.

[0069] For the specific settings of output component 2, refer to the attached Figure 7 To the attached Figure 12 In the embodiment shown, the drive assembly 22 includes:

[0070] A driving motor 221 is provided with a driving screw 222;

[0071] The driving slider 223 is fixedly mounted on the piston 21 and is screwed to the driving screw;

[0072] The piston 21 is cylindrical with an open upper end, and the upper end is connected to the driving slider 223 . The driving screw 222 extends into the interior of the piston 21 .

[0073] The driving slider 223 converts the rotation of the driving motor 221 and the transmission screw 222 into linear motion and provides guidance, thereby achieving stable and high-precision motion of the piston 21. In terms of implementation, the driving slider 223 can be used to achieve linear motion through the driving rail 2231.

[0074] Regarding the control of the motion stroke, referring to one embodiment, a trigger member 2232 is provided on the driving slider 223, and a first position sensor 2233 and a second position sensor 2234 are provided on the side of the driving rail 2231, which respond to the trigger member 2232. The driving motor 221 is controlled by the first position sensor 2233 and the second position sensor 2234.

[0075] To improve the rotational accuracy and axial concentricity of the drive screw 222, in one embodiment, a sliding engagement member 224 is provided on the side of the drive screw 222 facing away from the drive motor 221. The inner ring of the sliding engagement member 224 rotates with the drive screw 222, and the outer ring slides against the inner wall of the piston 21. In practice, the sliding engagement member 224 can be a combined structure, comprising an inner thrust bearing 2241 and an outer sliding wear ring 2242. This arrangement reduces component precision requirements, while the use of standardized parts reduces production and assembly pressure. Similarly, to enhance the axial stability of the piston 21 during movement, in one embodiment, an annular wear ring 211 is provided on the end of the piston 21 facing away from the drive slider 223. The wear ring 211 slides against the inner wall of the cylinder 11. The wear ring 211 is arranged around the circumference of the piston 21 and has at least one release slit. The wear-resistant ring 211 extends in the axial direction of the piston 21 , and the ratio of its axial length to the diameter of the piston 21 is in a range of 0.1 to 0.7.

[0076] As will be readily understood from the foregoing, the piston 21 is generally cylindrical with a closed end. In terms of dimensional structure, referring to one embodiment, the ratio between the outer diameter of the piston 21 and its inner diameter ranges from 1.5 to 3; and the ratio between the outer diameter of the piston 21 and the outer diameter of the drive screw 222 ranges from 1.8 to 5. In terms of overall layout, referring to one embodiment, the cylinder 11, piston 21, and drive screw 222 are arranged vertically, with the drive motor 221 located above the drive screw 222 and the two connected via a coupling.

[0077] Regarding the details of the functional component 3, referring to one embodiment, the functional component 3 includes a gas-liquid separation tank 33, the top of which is connected to the air pump 32, and the middle or bottom of which is connected to the exhaust passage 31. The gas-liquid separation tank 33 can achieve gas-liquid separation of the fluid discharged from the liquid storage tank 1 and provide a buffer space, thereby providing a structural basis for precise control.

[0078] For example, in the coordination setting of the emptying passage 31, referring to one embodiment, a liquid sensor 311 is provided on the emptying passage 31, and the on-off of the emptying passage 31 and / or the air pump 32 are controlled by the liquid sensor 311. The main function of the liquid sensor 311 is to judge the end point of the emptying process. When the liquid sensor 311 is triggered during the emptying process, it means that the emptying has been completed. In the actual structure, referring to one embodiment, the emptying passage 31 includes an emptying control valve 312 and a liquid sensor 311 for controlling the emptying passage 31 from the liquid storage tank 1 to the gas-liquid separation tank 33 in sequence. The advantage of setting the emptying control valve 312 before the liquid sensor 311 is that it can ensure the accuracy of the judgment of the end point of the emptying process. When the liquid sensor 311 is triggered, the possibility of air existing before the preceding emptying control valve 312 is greatly reduced, thereby avoiding the risk of incomplete emptying.

[0079] Regarding the configuration of the gas-liquid separation tank 33 itself, referring to one embodiment, a liquid level sensor 331 is provided on the gas-liquid separation tank 33, and the air pump 32 is controlled by the liquid level sensor 331. The liquid level sensor 331 is disposed outside the gas-liquid separation tank 33 and vertically below the connection point between the evacuation passage 31 and the gas-liquid separation tank 33. This configuration improves the stability of the liquid level sensor 331 and prevents it from being falsely triggered by disturbed fluid. Structurally, the liquid level sensor 331 is a capacitive type.

[0080] In addition to the physical liquid level sensor, the liquid level sensing in the present application can also be obtained by the control device based on the signal processing of other sensors. For example, in one embodiment, the functional component 3 includes a bubble sensor, which can detect bubbles in the gas-liquid separation tank. The bubble sensor can determine whether the piston pushes the gas or liquid level in the liquid storage tank into the gas-liquid separation tank. Therefore, based on the data of the bubble sensor, especially the continuous data of the bubble sensor, the control device can determine whether the piston and the liquid in the liquid storage tank are in complete contact. Once the bubble sensor does not continuously receive the bubble signal, it is considered that the piston is in complete contact with the liquid inside the liquid storage tank (that is, it is considered that the bubbles are emptied). At this time, the control device can calculate the current liquid level position in the liquid storage tank based on the operating state of the drive motor, and realize the function of controlling the liquid level based on this. In this embodiment, the liquid level of the working medium is confirmed by the coordinated cooperation of the bubble sensor and the drive motor; the control device realizes the liquid level control function without a direct liquid level sensor.

[0081] The liquid level sensor 331 on the separator tank 33 not only detects the amount of liquid in the separator tank 33 but also protects the air pump 32 by preventing it from drawing liquid from the separator tank 33 and causing unnecessary malfunctions. For a similar design logic, see one embodiment. A liquid-blocking device 332 is provided at the top of the separator tank 33, and the air pump 32 is connected to the liquid-blocking device 332. The provision of the liquid-blocking device 332 effectively ensures the stability of the air pump 32. Specifically, the liquid-blocking device 332 includes an air passage interconnected with the interior of the separator tank 33 and a liquid-blocking baffle 3322 disposed between the air passage opening 3321 and the drain passage 31. The liquid-blocking baffle 3322 is tilted and faces the bottom of the separator tank 33. Regarding the passage arrangement, a controllable liquid drainage passage 333 is provided at the bottom of the separator tank 33, the other end of which is connected to the bus bar 4.

[0082] In addition to the emptying process mentioned above, the functional component 3 can also provide more practical functions. For example, in one embodiment, the air pump 32 is a bidirectional air pump 32 and switches its working state relative to the emptying passage 31 through the air path switching valve 321. The air path switching valve 321 can realize the function switching of the air pump 32 to realize positive pressure or negative pressure on the emptying passage 31. During the emptying process, the air pump 32 can achieve negative pressure establishment for the gas-liquid separation tank 33, the emptying passage 31, the liquid storage tank 1 and the corresponding pipelines, thereby sucking the liquid into the corresponding position; during the purge process, the air pump 32 can achieve positive pressure establishment for the gas-liquid separation tank 33, the emptying passage 31, the liquid storage tank 1 and the corresponding pipelines, thereby blowing the fluid out of the corresponding position. This setting effectively improves the richness of the equipment functions without significantly increasing the burden on the equipment through the scientific setting of simple components, improving the user experience and providing a structural foundation for more functional settings.

[0083] For the overall layout, please refer to the attached Figure 1 and attached Figure 10In the illustrated embodiment, the aerosol therapy device includes an intersecting main frame 91 and a vertical frame 92 mounted on the main frame 91. The main frame 91 includes an operating area 911 located above and a pipeline area 912 located below. The vertical frame 92 is located in the operating area 911, and the output assembly 2 is mounted on the vertical frame 92. Furthermore, the vertical frame 92 divides the operating area 911 into a mechanical area 9111 and an electrical area 9112. The electrical area is provided with a control circuit 9113 located at the rear of the main frame 91 and a control device 9114 located at the front of the main frame 91. The liquid outlet passage 14 includes a liquid outlet connection port 141 for connecting to consumables. The liquid outlet connection port 141 is located in the pipeline area 912 and below the control device 9114. A main liquid inlet 41 and a main liquid outlet 42 are provided at the rear of the vertical frame 92. The liquid inlet passage 13 extends around one side of the main frame 91 to the pipeline area 912. Busbar 4 is located on the side of and below the main frame 91. The corresponding pipelines in pipe section 912 communicate with the main liquid outlet 42 via busbar 4. A through-hole 913 is provided in the main frame 91. The barrel 11 of the liquid storage tank 1 is positioned within through-hole 913. The heating plate 12 is positioned within pipe section 912. Through-hole 913 is located in front of the vertical frame 92.

[0084] The above-mentioned setting divides the space into regular areas through the main frame 91 and the vertical frame 92 installed on the main frame 91. The various components cooperate with each other in the corresponding areas. The overall equipment works independently while being compactly arranged and is not prone to mutual interference. While improving stability, it provides a good foundation for the overall appearance design of the product.

[0085] It is not difficult to understand that the present application also discloses a control method for an atomization therapy device, which is used to control the atomization therapy device to implement a preset operation on a working medium. The atomization therapy device includes a heatable liquid storage tank 1, a piston 21 that can apply pressure to the liquid storage tank 1, and an air pump 32 that can establish negative pressure or positive pressure in the liquid storage tank 1. The control method includes:

[0086] During the liquid filling process, the piston 21 withdraws from the liquid storage tank 1 and / or the air pump 32 works to achieve negative pressure liquid filling in the liquid storage tank 1;

[0087] During the emptying process, the piston 21 enters the liquid storage tank 1 and / or the air pump 32 works to empty the liquid storage tank 1;

[0088] During the temperature control process, the working medium is adjusted to a preset temperature by heating the liquid storage tank 1;

[0089] During the delivery process, the piston 21 enters the liquid storage tank 1 and / or the air pump 32 works to increase the pressure in the liquid storage tank 1 to a preset pressure. When the preset conditions are met, the working medium leaves through the liquid outlet passage 14 of the liquid storage tank 1 and realizes the corresponding function. In the subsequent process, the atomization treatment device enters the liquid storage tank 1 and / or the air pump 32 works through the piston 21 to maintain the pressure value of the working medium.

[0090] 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 step may be performed multiple times. The following describes the working process with the example of the atomization treatment device mentioned above.

[0091] During the liquid inlet process, the liquid inlet solenoid valve 131 on the liquid inlet passage 13 is opened, the drive motor 221 reverses to drive the transmission screw 222 to rotate, so that the drive slider 223 drives the piston 21 to move upward, so that negative pressure is formed in the liquid storage tank 1, and the working medium enters the liquid storage tank 1 through the liquid inlet solenoid valve 131 due to the negative pressure.

[0092] During this process, the air pump 32 can also cooperate to improve the efficiency of liquid intake. In terms of cooperation, in one embodiment, the operation of the air pump 32 and the movement of the piston 21 work synchronously and cooperatively. For example, during the upward movement of the piston 21, the air pump 32 synchronously establishes a negative pressure in the liquid storage tank 1. In another embodiment, the operation of the air pump 32 and the movement of the piston 21 work in steps. For example, before the liquid inlet solenoid valve 131 is opened, the air pump 32 first establishes a negative pressure in the liquid storage tank 1, and then opens the liquid inlet solenoid valve 131 and drives the piston 21 to move upward to achieve liquid intake. Similarly, during the movement of the piston 21, the air pump 32 can be set to keep working all the time, or it can be set to stop working before the piston 21 starts to move and the connection between the air pump 32 and the liquid storage tank 1 is disconnected by the drain control valve.

[0093] During the emptying process, the emptying solenoid valve in the emptying passage 31 is opened, and the driving motor 221 rotates forward to drive the transmission screw 222 to rotate, so that the driving slider 223 drives the piston 21 to move downward, so that the upper air in the liquid storage tank 1 is discharged through the emptying solenoid valve. When the liquid sensor 311 detects the liquid, it is determined that the air has been emptied, and the emptying solenoid valve and the driving motor 221 are closed.

[0094] In another embodiment, the emptying process is different. The emptying solenoid valve in the emptying passage 31 is opened, and the drive motor 221 rotates forward to drive the transmission screw 222 to rotate, so that the drive slider 223 drives the piston 21 to move downward, so that the upper air in the liquid storage tank 1 is discharged through the emptying solenoid valve. When the bubble sensor does not continuously receive the bubble signal, it is determined that the air has been emptied, and the emptying solenoid valve and the drive motor 221 are closed; and the liquid level height in the liquid storage tank 1 is calculated based on the current operation data of the drive motor 221.

[0095] During this process, the air pump 32 can also cooperate to improve the emptying efficiency, especially when the temperature of the working medium in the liquid storage tank 1 is high, the negative pressure caused by the upward movement of the piston 21 may cause the working medium to be vaporized more, resulting in insufficient negative pressure and other working conditions.

[0096] During the temperature control process, the heating plate 12 is started to heat the liquid in the liquid storage tank 1, and the temperature is fed back in real time by the temperature sensor 124. The temperature is controlled to be constant by software.

[0097] During the delivery process, the liquid outlet solenoid valve 142 in the liquid outlet passage 14 is opened, and the drive motor 221 rotates forward, driving the transmission screw 222, causing the drive slider 223 to move the piston 21 downward. The working medium passes through the liquid outlet solenoid valve 142 at a constant flow rate and / or pressure, enters the consumable through the liquid outlet connection port 141, and performs the corresponding operation.

[0098] As mentioned above, the functional component 3 can also realize more abundant functions. Referring to an embodiment, the control method of the atomization treatment device further includes:

[0099] During the purge process, the air pump 32 works to empty the liquid storage tank 1 and the corresponding passage.

[0100] During the waste liquid process, the working medium enters the liquid storage tank 1 through the piston 21 and / or the air pump 32 works to enable the working medium to enter the bus 4 through the waste liquid passage 15 of the liquid storage tank 1.

[0101] Similarly, the above processes do not limit the order in which they are performed. In actual implementation, the order of the steps may be adjusted, and a step may be performed multiple times or independently. The following describes the working process using the above-mentioned atomization treatment device as an example.

[0102] During the purging process, for example, when the nebulizer therapy device is transported or completely used, it is necessary to empty all the remaining liquid in the pipeline and the liquid storage tank 1. The gas-liquid separation tank 33 can be passed through positive pressure. When the emptying solenoid valve is opened, positive pressure is passed into the liquid storage tank 1, and then by opening and closing other solenoid valves, all the remaining liquid can be discharged.

[0103] During the waste liquid process, the waste liquid solenoid valve 151 in the waste liquid passage 15 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 downward, thereby discharging the working medium from the liquid storage tank 1. During this process, the air pump 32 can also cooperate to improve the efficiency of waste liquid discharge, especially the waste liquid in the pipeline. With the cooperation of the air pump 32, repeated flushing operations can be effectively avoided.

[0104] Similar to the liquid inlet process, during the purging process and the waste liquid process, the operation of the air pump 32 and the movement of the piston 21 can also be set to synchronous collaborative operation and step-by-step operation. In the synchronous collaborative operation, during the downward movement of the piston 21, the air pump 32 synchronously establishes a positive pressure in the liquid storage tank 1. In the step-by-step operation, the waste liquid solenoid valve 151 is opened to drive the piston 21 to move downward to discharge the working medium in the liquid storage tank. When the piston runs to the bottom dead point, the air pump 32 works to establish a positive pressure in the liquid storage tank 1 to discharge the working medium in the pipeline. In the above working process, the connection between the air pump 32 and the liquid storage tank 1 can be disconnected by the drain control valve.

[0105] Regarding the medium transportation, please refer to the attached Figure 11 To the attached Figure 17 In the embodiment shown, the present application discloses an atomizing handle 5 connected to an air pipeline and a liquid pipeline. The atomizing handle 5 includes a grip body 51 and a temperature control component 52 disposed in the grip body 51. The temperature control component 52 includes:

[0106] The heating seat 521 is fixedly arranged on the atomizing handle 5;

[0107] The heating tube 522 is fixedly installed in the heating seat 521. The interior of the heating tube 522 is hollow and one end is connected to the liquid pipeline, and the other end is connected to the liquid feeding port 5221. The liquid feeding port 5221 is provided on the outer peripheral surface of the grip body 51;

[0108] The spoiler component 523 is arranged inside the heating tube 522 and occupies the central space of the heating tube 522. The gap between the spoiler component 523 and the heating tube 522 is the heating path 524. The working medium in the liquid pipeline is attached to the inner wall of the heating tube 522 through the heating path 524 and passes through the heating tube 522.

[0109] The heating tube 522 can achieve thermal compensation for the working medium, thereby achieving temperature control at the handle end, improving the temperature control accuracy while improving the temperature control response, and avoiding delays caused by long-distance transportation. The setting of the spoiler component 523 can improve the working efficiency of the heating tube 522, control the overall volume of the atomizer handle 5 under the same heating performance, and improve the user experience. Figure 17 The heating path 524 shown in the figure only represents one of the running directions, and the actual running direction of the working medium is not limited to the direction indicated by the arrow.

[0110] In a specific embodiment, referring to one embodiment, the spoiler assembly 523 includes a placeholder 5231, which is a rod extending along the heating tube 522, with the axis of the heating tube 522 located within the placeholder 5231. In the accompanying drawings, the heating tube 522 is a cylindrical structure, and the placeholder 5231 is a rod-shaped structure. The ratio between the outer diameter of the placeholder 5231 and the inner diameter of the heating tube 522 ranges from 0.4 to 0.98. Independently of each other, the spoiler assembly 523 includes a spoiler 5232, which is disposed on the outer circumference of the placeholder 5231 and extends in the axial direction of the placeholder 5231. The gap between the spoiler 5232 and the inner wall of the heating tube 522 defines the heating path 524. The spoiler 5232 can change the movement path of the working medium, thereby increasing the heat exchange area while maintaining the overall size of the heating tube 522. In detail, the spoiler 5232 is spirally arranged around the outer circumference of the placeholder 5231, with the inner edge of the spoiler 5232 abutting against the outer circumference of the placeholder 5231, and the outer edge of the spoiler 5232 abutting against the inner circumference of the heating tube 522. This abutting arrangement improves heat exchange efficiency while avoiding gaps in the fitting of components and preventing abnormal noise during the movement of the atomizer handle 5.

[0111] Referring to one embodiment, the axial ends of the placeholder 5231 form mating ends 5233, the radial dimensions of which are smaller than the radial dimensions of the middle portion of the placeholder 5231. The proximal end of the spoiler 5232 extends at least to the periphery of the mating ends 5233 on the proximal side of the placeholder 5231. The gap between the spoiler 5232 and the mating ends 5233 on the proximal side of the placeholder 5231 forms the heating inlet 5241 of the heating path 524. The mating ends 5233 further constrain the installation accuracy of the placeholder 5231, thereby improving the dimensional accuracy of the heating path 524 and enhancing the heat exchange effect. The aforementioned heating inlet 5241 can also be positioned distally of the placeholder 5231 to form a heating outlet, further extending the heat exchange path.

[0112] In addition to the temperature control settings for the liquid channel mentioned above, you can also refer to the attached Figure 18 As shown, the interior of the heating seat 521 is hollow and forms a heat-averaging cavity 5211. The heating tube 522 runs through the heat-averaging cavity 5211. The internal space of the heat-averaging cavity 5211 can exchange heat with the outer surface of the heating tube 522. The heat-averaging cavity 5211 can make full use of the heating area of ​​the heating tube 522 and provide more heat exchange space. In detail, the heat-averaging cavity 5211 is sealed and is provided with a heat-averaging inlet 5212 and a heat-averaging outlet 5213, one of which is connected to the gas pipeline and the other is connected to the air supply port. The heating of the gas and liquid phases by the same heating tube 522 can ensure the heating temperature while controlling the number and volume of the overall components, avoiding unnecessary heat loss. In the attached Figure 19In the embodiment shown, the heat-averaging chamber 5211 is also connected to a first thermocouple mounting port 5216 and a second thermocouple mounting port 5217. The thermocouples arranged at the far and near 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-controlled atomization system adjusts the flow rate of the liquid medium and / or the gaseous 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 the heating element connection port 5214 and the heating element connection port 5215. This setting can avoid unnecessary heat exchange between the heat-averaging chamber and the external space due to the pipeline setting. The heat-averaging chamber can ensure a stable temperature, thereby better achieving the heat-averaging effect of the gas path.

[0113] In this embodiment, the gas and liquid phases only exchange heat near the heating tube 522, while remaining isolated from each other. This prevents premature mixing of media with different pressures and properties, which could affect subsequent atomization. Structurally, the heating tube 522 is sealed. The working medium in the liquid conduit exchanges heat with the inner surface of the heating tube 522, while the working medium in the gas conduit exchanges heat with the outer surface of the heating tube 522.

[0114] In actual use, the gas and the heated liquid finally converge at the distal end of the interventional catheter and realize the atomization function through the interventional catheter and the mixed flow structure in the catheter. The gas needs to be preliminarily heated before the gas and liquid converge. In this embodiment, the inner cavity of the heating tube can heat the liquid, and the outer cavity can preliminarily heat the gas, thereby reducing the problem of the gas taking away the liquid temperature before the liquid and gas are mixed.

[0115] Based on the above description, the present application discloses a temperature-controlled atomization system, including an atomization treatment device for providing a liquid medium and a gaseous medium, an atomization handle 5, and an interventional catheter. The atomization treatment device includes a liquid storage tank 1 for receiving, temperature-controlling, and delivering a working medium, and an output component 2 for establishing positive or negative pressure in the liquid storage tank 1; the output component 2 delivers the working medium in the liquid storage tank 1 that meets preset conditions to the atomization handle 5;

[0116] The atomizing handle 5 includes a gripping body 51 and a temperature control component 52 disposed in the gripping body 51. The temperature control component 52 independently processes the liquid phase medium and the gas phase medium to a preset temperature and delivers them to the distal end of the interventional catheter.

[0117] A mixed flow structure is provided at the distal end of the interventional catheter, and liquid phase medium and gas phase medium that meet preset conditions are mixed in the mixed flow structure and atomized.

[0118] The proximal end of the interventional catheter is connected to the air and liquid pipelines (i.e., the liquid delivery port and the air delivery port) of the atomization handle, and delivers the corresponding liquid medium and gas medium to its distal end to achieve atomization.

[0119] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they 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 deemed that the drawing also discloses examples of combinations of the various embodiments involved.

[0120] The above-described embodiments merely represent several implementation methods of the present application. 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 a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
