Description

Technical Field

[0001] This application relates to the field of liquid atomization, and more specifically, to a method for controlling atomization, an atomization system, and a device for controlling atomization. Background Technology

[0002] A nebulizer is a device that mixes liquid medication with gaseous air. The mixture is delivered through both liquid and air pathways at a specific point in the system, creating droplets with a diameter of tens of micrometers, thus atomizing the liquid. To achieve better and faster atomization, a multi-step control method is typically required. This involves maintaining a stable output air pressure, but variations in the air pump, air path, and load can cause gas pressure instability, necessitating a wide air pressure output range.

[0003] The nebulization scheme in related technologies involves resetting the syringe plunger to its original position, then turning on the air pump and waiting for the air pressure to rise to the target value. Immediately afterward, the air pump begins to push the syringe at a set flow rate to initiate nebulization. The plunger approaches the syringe at a preset speed; upon contact, medication is output from the liquid path. The injection stops after the syringe is fully dispensed, and then the air pump output is turned off. However, directly turning off the air pump output after the syringe is completely dispensed results in some medication remaining in the mixing device, preventing further nebulization and causing medication waste.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0005] This application provides a method, system, and apparatus for controlling atomization, to at least solve the technical problem of drug waste caused by long waiting time for drug atomization and insufficient atomization in related technologies.

[0011] Optionally, the above method further includes: restoring the push handle from its current position to the target position after the atomization operation is completed.

[0012] Optionally, the plunger is suitable for injecting syringes of various lengths. The origin position of the plunger is adapted to at least one length of syringe. Restoring the plunger from its current position to the target position includes: determining the origin position of the plunger as the target position and restoring the plunger from its current position to the origin position; or obtaining the target length of the syringe to be injected during the target time period, determining the target position of the plunger based on the target length and the current position of the plunger, and restoring the plunger to the target position.

[0013] According to another aspect of the embodiments of this application, a method for controlling atomization is also provided. This method is applied to an atomization system, wherein the liquid path of a mixing device in the atomization system is connected to a target syringe and a first gas outlet of a gas source, and the gas path of the mixing device in the atomization system is connected to a second gas outlet of the gas source. The method includes: displaying a human-machine interface; responding to an atomization command detected in the human-machine interface, opening the gas path of the mixing device to inject gas output from the gas source into the gas path through the second gas outlet; when the gas pressure in the gas path rises to a first target gas pressure, using a push handle to control the target syringe to push liquid medication into the liquid path of the mixing device at a preset speed to perform an atomization operation on the liquid medication in the liquid path; and after the atomization operation is completed, opening the first gas outlet to inject gas from the gas source into the liquid path through the first gas outlet to completely atomize the remaining liquid medication in the mixing device.

[0015] According to another aspect of the embodiments of this application, a device for controlling atomization is also provided. This device is applied to an atomization system. The liquid path of the mixing device in the atomization system is connected to the target syringe and the first gas outlet of the gas source. The gas path of the mixing device in the atomization system is connected to the second gas outlet of the gas source. The device includes: a first control module for opening the gas path of the mixing device to inject gas output from the gas source into the gas path through the second gas outlet; a second control module for controlling the target syringe to push liquid medicine into the liquid path of the mixing device at a preset speed using a push handle when the gas pressure in the gas path rises to a first target gas pressure, so as to perform an atomization operation on the liquid medicine in the liquid path; and an atomization module for opening the first gas outlet after the atomization operation is completed, injecting gas from the gas source into the liquid path through the first gas outlet, so as to completely atomize the remaining liquid medicine in the mixing device.

[0018] In this embodiment, gas is injected into the gas path and liquid path of the mixing device at different times through the first gas outlet and the second gas outlet. Specifically, during the atomization operation, the gas path of the mixing device is opened to inject the gas output from the gas source into the gas path through the second gas outlet. When the gas pressure in the gas path rises to the first target gas pressure, the push handle is controlled to push the target syringe at a preset speed to push the liquid into the liquid path to perform an atomization operation on the liquid in the liquid path. After the atomization operation is completed, the first gas outlet is opened to inject the gas from the gas source into the liquid path to completely atomize the remaining liquid in the mixing device. This achieves the technical effects of shortening the injection time, fully atomizing the liquid, saving atomization time, and avoiding liquid waste. This solves the technical problem of liquid waste caused by long liquid atomization waiting time and insufficient liquid atomization in related technologies. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] According to an embodiment of this application, a method for controlling atomization is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] Figure 1 This application discloses a method for controlling atomization according to an embodiment of the present application. The method is applied to an atomization system, wherein the liquid path of the mixing device in the atomization system is connected to the target injector and the first gas outlet of the gas source, and the gas path of the mixing device in the atomization system is connected to the second gas outlet of the gas source. Figure 1 As shown, the method includes:

[0030] Step S102: Open the gas path of the mixing device to inject the gas output from the gas source into the gas path through the second gas outlet;

[0031] In the above-mentioned technical solution of step S102, before the liquid medicine is pushed into the liquid path of the mixing device, gas is introduced into the gas path of the mixing device to increase the internal pressure of the gas path and prevent the liquid medicine in the liquid path from flowing back into the gas path of the mixing device when the liquid medicine is pushed into the liquid path of the mixing device.

[0032] Step S104: When the air pressure in the air path rises to the first target air pressure, the target syringe is controlled by the push handle to push the drug liquid into the liquid path of the mixing device at a preset speed to perform the atomization operation of the drug liquid in the liquid path.

[0033] Step S106: After the atomization operation is completed, open the first gas outlet and inject the gas from the gas source into the liquid path through the first gas outlet to completely atomize the remaining liquid in the mixing device.

[0034] In the technical solution of step S106 above, injecting gas into the liquid path through the first gas outlet allows the internal cavity of the liquid path to maintain pressure output through the output gas from the first gas outlet, accelerating atomization output until the remaining liquid medicine in the mixing device is completely atomized. Simultaneously, the injected gas can push the remaining liquid medicine out of the liquid path cavity, significantly reducing the amount of liquid medicine residue inside the liquid path cavity and effectively avoiding waste. The first target gas pressure can be set according to actual needs; for example, the first target gas pressure can be any pressure value between 70 kPa and 200 kPa, and this specification does not limit it.

[0035] In the aforementioned method for controlling atomization, gas is injected into the gas path and liquid path of the mixing device at different times through the first gas outlet and the second gas outlet, respectively. Specifically, during the atomization operation phase, the gas path of the mixing device is opened to inject the gas output from the gas source into the gas path through the second gas outlet. When the gas pressure in the gas path rises to the first target gas pressure, the push handle is controlled to push the target syringe at a preset speed to push the liquid into the liquid path to perform an atomization operation on the liquid in the liquid path. After the atomization operation is completed, the first gas outlet is opened to inject the gas from the gas source into the liquid path to completely atomize the remaining liquid in the mixing device. This achieves the technical effects of shortening the injection time, fully atomizing the liquid, saving atomization time, and avoiding liquid waste. It also solves the technical problem of liquid waste caused by long liquid atomization waiting time and insufficient liquid atomization in related technologies.

[0036] In some embodiments of this application, opening the first gas outlet can be achieved by first starting a first delay countdown and then opening the first gas outlet after the first delay countdown ends. It should be noted that the delay can ensure that a large amount of gas does not enter the mixing device before the liquid, thus avoiding a section of the liquid path of the mixing device being entirely filled with gas. The first delay countdown can be set according to actual needs, such as 5 seconds or 10 seconds, etc. This specification does not limit this.

[0037] As an optional implementation, the decision to open the gas path of the mixing device can be made by: determining whether the internal cavity of the liquid path of the mixing device is filled; if the internal cavity of the liquid path of the mixing device is found to be filled, opening the gas path of the mixing device; if the internal cavity of the liquid path of the mixing device is not found to be filled, controlling the push handle to push the target syringe to inject the drug solution into the liquid path of the mixing device so that the drug solution fills the internal cavity of the liquid path.

[0038] In an optional embodiment of this application, controlling the plunger to push the target syringe into the liquid path of the mixing device to inject the drug solution can be achieved through the following steps: Specifically, gas output from the gas source can be injected into the gas path of the mixing device through the second gas outlet, and when the gas pressure inside the mixing device rises to the second target gas pressure, the plunger is controlled to push the target syringe into the liquid path to inject the drug solution at different speeds. It should be noted that the specific value of the above-mentioned second target gas pressure can be determined experimentally, and preferably, the gas pressure value that can achieve a better atomization effect is used as the second target gas pressure, which can be 100 kPa.

[0039] Specifically, controlling the plunger to push the target syringe at different speeds to inject medication into the liquid path includes: controlling the plunger to move towards the target syringe filled with medication at a first speed, and detecting the pressure value of the plunger; if the pressure value of the plunger is greater than a first preset pressure value, controlling the plunger to move towards the target syringe at a second speed to inject the medication into the liquid path of the mixing device, wherein the first preset pressure value is the pressure value sensed on the end face of the plunger when the plunger contacts the syringe, and the first speed is greater than the second speed; if the pressure value of the plunger is greater than the second preset pressure value, stopping the movement of the plunger and starting a second delay countdown; and closing the second gas outlet when the second delay countdown ends, wherein the second preset pressure value is the pressure value of the plunger when the internal cavity of the liquid path is filled. In other words, controlling the plunger to initially inject at a faster speed, and then slowing down when the plunger contacts the syringe, this technical solution saves working time while ensuring sufficient injection. Figure 2 This is a schematic diagram showing the positions of the syringe and plunger in some embodiments of this application, such as... Figure 2 As shown, a pressure sensor is installed on the push handle, which can acquire the pressure value at the push handle end in real time. The second delay countdown can be set according to actual needs, such as 5 seconds or 10 seconds, etc., and this manual does not limit this setting.

[0040] It should be noted that if the second gas outlet is closed too early, the liquid medicine may flow back from the liquid path to the gas path, which may prevent normal atomization in the first few seconds of the atomization operation. Therefore, by delaying the closure of the second gas outlet, the liquid medicine can be prevented from flowing back from the liquid path to the gas path, thus ensuring the normal atomization process.

[0041] In some embodiments of this application, after the nebulization operation is completed, in order to ensure the smooth progress of the next nebulization operation, it is necessary to restore the plunger from its current position to the target position. It should be noted that the plunger in the relevant embodiments of this application is suitable for injecting syringes of various lengths. The origin position of the plunger is adapted to at least one syringe length. In some embodiments, the origin position can be used to inject the longest syringe among various lengths; that is, the longest syringe can be injected at the origin position. It is understood that if the longest syringe can be injected at the origin position, then syringes of other lengths can also be injected at the origin position.

[0042] Therefore, as an optional implementation, restoring the push handle from its current position to the target position includes: determining the origin position of the push handle as the target position, and restoring the push handle from its current position to the origin position.

[0043] As another alternative implementation, restoring the plunger from its current position to the target position can also be achieved by: obtaining the target length specification of the syringe to be injected during the target time period, then determining the target position of the plunger based on the target length specification and the current position of the plunger, and restoring the plunger to the target position.

[0044] Optionally, determining the target position of the plunger based on the target length specification and the current position of the plunger, and then restoring the plunger to the target position, can be achieved by determining the distance the plunger needs to move based on the length corresponding to the target length specification and the current position of the plunger, determining the target position the plunger needs to return to based on the moving distance and the current position of the plunger, and then restoring the plunger to the target position. In other words, by determining the length of the syringe to be used, the required return position is determined. It is easy to note that compared to directly restoring the plunger to its original position, this method allows for flexible adjustment of the starting position of the plunger for injection based on the syringe to be used, offering greater flexibility and saving injection time, especially for shorter syringes, reducing the waiting time during injection.

[0045] Figure 3 This is another method for controlling atomization according to an embodiment of this application. The method is applied to an atomization system, wherein the liquid path of the mixing device in the atomization system is connected to the target injector and the first gas outlet of the gas source, and the gas path of the mixing device in the atomization system is connected to the second gas outlet of the gas source, such as... Figure 3 As shown, the method includes:

[0046] S302, showcasing the human-computer interaction interface;

[0047] S304, in response to the atomization command detected in the human-machine interface, the gas path of the mixing device is opened so that the gas output from the gas source is injected into the gas path through the second gas outlet. When the gas pressure in the gas path rises to the first target gas pressure, the push handle controls the target syringe to push into the liquid path of the mixing device at a preset speed to perform the atomization operation on the liquid in the liquid path.

[0048] S306, upon completion of the atomization operation, the first gas outlet is opened, and gas from the gas source is injected into the liquid path through the first gas outlet to completely atomize the remaining liquid in the mixing device.

[0049] In this method of controlling atomization, a human-machine interface is displayed. In response to an atomization command detected in the human-machine interface, the gas path of the mixing device is opened, allowing gas from the gas source to be injected into the gas path through a second gas outlet. When the gas pressure in the gas path rises to a first target gas pressure, the push handle controls the target syringe to push liquid into the liquid path of the mixing device at a preset speed to perform atomization of the drug solution in the liquid path. After the atomization operation is completed, the first gas outlet is opened, allowing gas from the gas source to be injected into the liquid path to completely atomize the remaining drug solution in the mixing device. This achieves the technical effects of shortening the injection time, fully atomizing the drug solution, saving atomization time, and avoiding drug waste. It also solves the technical problem in related technologies where long atomization waiting times and insufficient atomization lead to drug waste.

[0050] To facilitate a better understanding of the embodiments of this application by those skilled in the art, the above technical solutions are now described in conjunction with a specific embodiment:

[0051] 1. Connect the liquid circuit of the mixing device to the syringe and the first gas outlet, and connect the gas circuit of the mixing device to the second gas outlet of the gas source device.

[0052] 2. The user inputs the target injection flow rate and target gas pressure value through the screen. The flow rate range is generally 1-5 ml / min, and the gas pressure range is generally 70 kPa-200 kPa.

[0053] 3. When the user clicks "Reset," the plunger quickly returns to its original position, allowing the syringe to be installed.

[0054] 4. The user clicks "Initialize" and waits for the push handle to quickly contact the push handle first, then slowly pushes the liquid medicine into the mixing device.

[0055] 5. The user clicks the atomization button and waits for the atomization process to complete.

[0056] Specifically:

[0057] 1. Reset Operation: When the user presses the reset button, in response to the reset button (i.e., in response to the reset command), the push handle will quickly return from any position to the set origin position (see...). Figure 2 (The position of the push handle).

[0058] 2. Initialization Operation: First, the gas path is opened, and a stable gas pressure output is maintained through a PID control algorithm until the gas pressure rapidly rises to 100 kPa (i.e., the second target gas pressure). Then, the plunger moves rapidly towards the syringe at a first speed. When the pressure sensor at the plunger end reaches the first pressure value, it is determined that the plunger has fully contacted the syringe (or the contact sensor is used to determine whether the plunger and syringe have fully contacted). At this time, the flow rate is reduced, and the liquid medication is fully pushed from the syringe into the mixing device at a second speed. When the pressure at the plunger end reaches the second pressure value (which can be determined in advance through experiments; this value is usually determined by the mixing device, such as the experimental value of the liquid medication capacity that the mixing device can hold), it is determined that the liquid medication has fully entered the mixing device. At this time, the syringe injection is immediately stopped, and the second delay countdown begins. The gas path output is closed after a delay, and the second gas outlet of the gas source is closed at the end of the delay (about 5 seconds), completing the initialization operation. It should be noted that the liquid path capacity of the mixing device is less than that of the syringe. After the initialization operation, the liquid path in the mixing device is filled with liquid medication, and the remaining liquid medication will remain in the syringe, awaiting the next nebulization operation.

[0059] 3. Nebulization Operation: First, the gas path can be opened and the PID control algorithm can be used to maintain a stable gas pressure output. When the gas pressure rises rapidly to the target gas pressure (i.e., the first target gas pressure, the reference gas pressure range is 70Kpa-200Kpa, and the upper limit of the gas pressure can be increased if the gas source performance is sufficient), the syringe is pushed at a preset speed and the first delay countdown (1-3 seconds) is started. When the first delay countdown ends, the first gas outlet connected to the liquid path is opened to start the nebulization process, and the injection is stopped after the syringe is pushed to the preset position.

[0060] Understandably, the above preset positions can be divided into two cases: 1. The position corresponding to 0ml when the liquid in the syringe is completely pushed out; 2. The position corresponding to the set injection volume. It should be noted that the gas output through the first gas outlet and the second gas outlet can completely push out the remaining liquid in the syringe, so that it can completely atomize the liquid in the mixing device. After confirming that the liquid in the mixing device is completely atomized, the output of the first gas outlet and the second gas outlet is turned off.

[0061] Figure 4 This is an atomization system according to an embodiment of this application, such as... Figure 4 As shown, the atomization system includes:

[0062] The gas source device is equipped with a first gas outlet and a second gas outlet;

[0063] A syringe connected to a liquid outlet;

[0064] The mixing device is equipped with a liquid path and a gas path. The liquid path of the mixing device is connected to the liquid outlet and the first gas outlet through a three-way valve, and the gas path of the mixing device is connected to the second gas outlet.

[0065] This atomization system can completely atomize the remaining liquid medicine in the mixing device by receiving control commands, thereby shortening the injection time, fully atomizing the liquid medicine, saving atomization time, and avoiding liquid medicine waste. It also solves the technical problem of liquid medicine waste caused by long atomization waiting time and insufficient atomization in related technologies.

[0066] Figure 5 This is a schematic diagram of the atomization system in an exemplary embodiment of this application, as shown below. Figure 5 As shown, in this atomization system, a valve is installed between the gas source and the first gas outlet. The liquid outlet is connected to the first gas outlet through a three-way valve, and then connected to the liquid circuit of the mixing device through an extension pipe. The second gas outlet is connected to the gas circuit in the mixing device through an extension pipe.

[0067] Figure 6 This application discloses a device for controlling atomization according to an embodiment of the present application. The device is applied in an atomization system. The liquid path of the mixing device in the atomization system is connected to the target injector and the first gas outlet of the gas source. The gas path of the mixing device in the atomization system is connected to the second gas outlet of the gas source. Figure 6 As shown, the device includes:

[0068] The first control module 60 is used to open the gas path of the mixing device so that the gas output from the gas source is injected into the gas path through the second gas outlet;

[0069] The second control module 62 is used to control the target syringe to inject the drug solution into the liquid path of the mixing device at a preset speed when the gas pressure in the gas path rises to the first target gas pressure, so as to perform the atomization operation of the drug solution in the liquid path.

[0070] The atomization module 64 is used to open the first gas outlet after the atomization operation is completed, and inject the gas from the gas source into the liquid circuit through the first gas outlet so as to completely atomize the remaining liquid medicine in the mixing device.

[0071] In this atomization control device, the first control module 60 is used to open the gas path of the mixing device to inject the gas output from the gas source into the gas path through the second gas outlet; the second control module 62 is used to control the target injector to push the liquid into the liquid path of the mixing device at a preset speed when the gas pressure in the gas path rises to the first target gas pressure, so as to perform the atomization operation on the liquid in the liquid path; the atomization module 64 is used to open the first gas outlet after the atomization operation is completed, and inject the gas from the gas source into the liquid path through the first gas outlet to completely atomize the remaining liquid in the mixing device. This achieves the technical effects of shortening the injection time, fully atomizing the liquid, saving atomization time, and avoiding liquid waste, thereby solving the technical problem of liquid waste caused by long liquid atomization waiting time and insufficient liquid atomization in related technologies.

[0072] According to another aspect of the embodiments of this application, a non-volatile storage medium is also provided, the storage medium including a stored program, wherein, when the program is running, it controls the device where the storage medium is located to execute any method of controlling atomization.

[0073] Specifically, the aforementioned storage medium is used to store program instructions for the following functions, thereby implementing the following functions:

[0075] The system displays a human-machine interface; in response to an atomization command detected in the human-machine interface, it opens the gas path of the mixing device to inject the gas output from the gas source into the gas path through the second gas outlet. When the gas pressure in the gas path rises to the first target gas pressure, the push handle controls the target syringe to push the liquid into the liquid path of the mixing device at a preset speed to perform an atomization operation on the liquid in the liquid path; after the atomization operation is completed, it opens the first gas outlet to inject the gas from the gas source into the liquid path through the first gas outlet to completely atomize the remaining liquid in the mixing device.
