[0002] This application claims priority to Chinese Patent Application No. 202411732041.X, entitled "Automatic Foaming Control Method and System", filed on November 29, 2024, with the China National Intellectual Property Administration, the entire contents of which are incorporated herein by reference. Technical Field

[0004] In medical imaging examinations, contrast agents are typically administered to enhance the contrast between the target tissue or organ and surrounding tissues, resulting in clearer scanned images. This allows doctors to observe and interpret the images more clearly, enabling them to detect subtle lesions or abnormalities. In general settings, contrast agents are usually prepared by mixing and foaming saline, blood, and air.

[0005] However, contrast agents are currently mainly prepared and delivered manually. This involves manually injecting and mixing saline, blood, and air through a syringe to prepare and deliver the contrast agent to the target. This results in a large workload, low efficiency, and cannot avoid the deviations that may occur during manual operation. Summary of the Invention

[0110] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0111] Example 1

[0112] The automatic foaming control method provided in Embodiment 1 of this application can be applied to the application environment shown in Figure 1. The ultrasound contrast imaging preparation device 102 is detachably connected to the trolley 104, and the ultrasound contrast imaging preparation device 102 is mounted in the movable trolley 104. The ultrasound contrast imaging preparation device 102 triggers commands through an interactive interface to automatically prepare the contrast agent. The ultrasound contrast imaging preparation device 102 displays a user interface. The user interface includes trigger controls for at least one foaming mode. The ultrasound contrast imaging preparation device 102 automatically prepares the contrast agent in response to trigger operations of the trigger controls for at least one foaming mode.

[0113] In one embodiment, as shown in Figure 2, an automatic foaming control method is provided. Taking the application of this method to the ultrasound contrast imaging preparation device 102 in Figure 1 as an example, the method includes the following steps:

[0114] S202, Display the user interface. The user interface includes at least one trigger control for a bubble mode.

[0115] The foaming mode trigger control is used to control the ultrasound contrast agent preparation device to automatically prepare the contrast agent. The foaming mode includes at least one of the following: resting mode, pressure mode, and combined mode. The resting mode is a foaming mode that does not require the target subject to inhale air and can be directly delivered after successful contrast agent preparation. The pressure mode is a foaming mode that requires the target subject to inhale air to the required level before contrast agent delivery. The combined mode is a mode that combines multiple foaming modes. For example, the combined mode can be a combination of resting mode and pressure mode, or a combination of multiple resting modes, or a combination of multiple pressure modes.

[0116] The ultrasound contrast imaging preparation device includes a display screen, on which the user interface is displayed. The display screen can be a touchscreen that allows users to operate directly on the screen surface using their fingers or a stylus.

[0117] S204, in response to a trigger operation of a trigger control for at least one foaming mode, automatically prepares the contrast agent.

[0118] The trigger control for each foaming mode executes the contrast agent preparation process corresponding to that foaming mode. For example, the user interface includes a trigger control for the resting mode foaming mode. After the resting mode trigger control is triggered, the ultrasound contrast agent preparation device will prepare the contrast agent according to the resting mode process.

[0119] In some embodiments, if the user interface includes trigger controls for multiple bubble modes, then only one trigger control corresponding to a bubble mode can be triggered at a time when triggering the control.

[0120] In some embodiments, the ultrasound contrast agent preparation device also includes an emergency stop control. If any situation affecting the preparation of the contrast agent occurs during the foaming process of the ultrasound contrast agent preparation device, triggering the emergency stop control can stop the preparation of the contrast agent.

[0121] The aforementioned automated foaming method includes a user interface; this interface comprises trigger controls for at least one foaming mode; and the contrast agent is automatically prepared in response to trigger operations of the trigger controls for at least one foaming mode. This method reduces workload and improves efficiency. Furthermore, because the contrast agent preparation process is fully automated, it avoids deviations that may occur during manual operation, ensuring the consistency of contrast agent quality. In addition, since each step of the contrast agent preparation is automatically controlled, the foaming speed and quality can be precisely controlled, preventing situations where the foaming speed is too fast or too slow, resulting in poor-quality contrast agents that do not meet medical requirements.

[0122] In one embodiment, at least one foaming mode trigger control includes a resting mode trigger control. Automatic contrast agent preparation includes:

[0123] After resetting, an image is displayed showing the delivery assembly and the fluid lines connected to it being emptied. The delivery assembly is a component installed in the ultrasound contrast imaging preparation device.

[0124] After the delivery components and fluid lines have been emptied, images of the extracted air, saline, and blood are displayed until the extracted air, saline, and blood each reach their corresponding first preset extraction volume.

[0125] The image shows the delivery component repeatedly extracting and infusing air, saline, and blood until the number of extractions and infusions reaches a first preset number, thus obtaining the contrast agent.

[0126] Reset refers to restoring the components of the ultrasound contrast agent preparation device to their initial state or default settings. The reset of the ultrasound contrast agent preparation device can be performed after the previous contrast agent preparation is completed, or after the trigger control for the resting mode is activated. Alternatively, a reset can be performed once after the previous contrast agent preparation is completed, and also once after the trigger control for the resting mode is activated.

[0127] A delivery assembly is a component used to transport fluids, such as liquids or gases, from one location to another. Delivery assemblies include, but are not limited to, syringes and tubing.

[0128] The first preset extraction volume is a parameter pre-set in the ultrasound contrast imaging preparation device. Air, saline, and blood each have a corresponding first preset extraction volume.

[0129] In some embodiments, the ultrasound contrast imaging preparation device may also be equipped with a voice module to provide voice prompts for the actions currently being performed by the device. For example, voice prompts may indicate that the ultrasound contrast imaging preparation device has entered a resting mode, that the delivery assembly and fluid path are undergoing evacuation, that the delivery assembly is extracting air, saline solution, and blood, that the ultrasound contrast imaging preparation device is currently preparing the contrast agent, and that the contrast agent preparation is complete.

[0130] In some embodiments, since the contrast agent requires a delivery assembly for preparation, if the ultrasound contrast imaging preparation device does not have a delivery assembly installed, the user will be prompted to install the delivery assembly before displaying the evacuation process image. The prompt can be delivered via one or more of the following methods: voice prompts through the ultrasound contrast imaging preparation device's built-in voice module, text prompts through the device's display screen, or light prompts through the device itself. This ensures that the ultrasound contrast imaging preparation device prepares the contrast agent with the delivery assembly already installed, thus guaranteeing successful contrast agent preparation.

[0131] The purging action of the delivery assembly and the fluid circuit connected to the delivery assembly can be performed automatically after the delivery assembly is confirmed to be installed, or it can be performed after triggering the purging control included in the display screen of the ultrasound contrast imaging preparation device.

[0132] Images of air, saline solution, and blood being extracted are displayed on the screen of the ultrasound contrast imaging device. These images can be static images including the delivery components, or dynamic images of the delivery components extracting air, saline solution, and blood. The dynamic images can be real-time dynamic images of air, saline solution, and blood extraction, or simulated dynamic images of the delivery components extracting air, saline solution, and blood.

[0133] In some embodiments, the images showing the purging process of the delivery components and fluid lines, and the images showing the extraction of air, saline, and blood, can also display the objects extracted by each delivery component. For example, if delivery component A extracts air and delivery component B extracts saline, the displayed images can show delivery component A extracting air and delivery component B extracting saline (sodium chloride solution). Figure 3 shows an image of the purging process in resting mode, and Figure 4 shows an image of the extraction of air, saline, and blood.

[0134] The repeated extraction and infusion of air, saline, and blood by the delivery component can be performed automatically after the extraction of saline, air, and blood is complete, or it can be performed after triggering the preparation controls included in the display screen of the ultrasound contrast imaging preparation device.

[0135] The first preset number of times is a parameter set in advance in the ultrasound contrast agent preparation device. Only when the number of extractions and infusions reaches the first preset number of times can the contrast agent preparation be ensured to be successful.

[0136] Images of the repeated extraction and infusion of air, saline, and blood by the delivery component are displayed on the screen of the ultrasound contrast imaging preparation device, as shown in Figure 5. The displayed images of the repeated extraction and infusion of air, saline, and blood by the delivery component can be static images of the extraction and infusion, or dynamic images of the repeated extraction and infusion. The dynamic images can be real-time dynamic images of the repeated extraction and infusion of air, saline, and blood by the delivery component, or simulated dynamic images of the repeated extraction and infusion of air, saline, and blood by the delivery component.

[0137] In some embodiments, if the amount of saline sample drawn is insufficient to prepare the contrast agent, the contrast agent preparation task will be stopped, and the user will be notified that the amount of saline sample is insufficient, until the amount of saline sample drawn is sufficient to prepare the contrast agent. The amount of saline sample can be determined by the diameter of the saline channel in the ultrasound contrast imaging preparation device, the flow rate of the saline, and the flow time. Alternatively, when the bubble sensor in the ultrasound contrast imaging preparation device detects bubbles in the liquid, the size and frequency of these bubbles can be measured to calculate the air ratio, and then the saline ratio can be calculated based on the air ratio, thus determining the amount of saline sample drawn.

[0138] In some embodiments, when drawing blood, a blood oxygen sensor is used to detect the blood oxygen value of the collected blood. If the blood oxygen value is not within the normal range, the blood drawing will be stopped and an alarm will be output to alert the operator that the blood is abnormal.

[0139] In this first embodiment, after the ultrasound contrast imaging preparation device has been reset, images of the delivery component and the liquid path connected to the delivery component being emptied are displayed. After the delivery component has been emptied, images of air, saline, and blood being extracted are displayed until the extracted air, saline, and blood each reach their corresponding first preset extraction amount. Images of the delivery component repeatedly extracting and infusing air, saline, and blood are displayed until the number of extractions and infusions reaches the first preset number, thus obtaining the contrast agent. This allows the operator to intuitively see from the display screen of the ultrasound contrast imaging preparation device which step of contrast agent preparation in resting mode has been performed.

[0140] In one embodiment, at least one foaming mode trigger control includes a pressure mode trigger control. Automatic contrast agent preparation includes:

[0141] After resetting is complete and the air-blowing exercise of the target object to be delivered contrast agent is successful, an image is displayed showing the delivery assembly and the fluid path connected to the delivery assembly undergoing evacuation. The delivery assembly is a component installed in the ultrasound contrast imaging preparation device.

[0142] After the delivery components and fluid lines have been emptied, images of the extracted air, saline, and blood are displayed until the extracted air, saline, and blood each reach their corresponding second preset extraction volume.

[0143] The image shows the delivery component repeatedly extracting and infusing air, saline, and blood until the number of extractions and infusions reaches a second preset number, thus obtaining the contrast agent.

[0144] "Reset" refers to restoring all components of the ultrasound contrast imaging preparation device to their initial state or default settings. "Blowing exercise" refers to the blowing practice performed on the target subject to be delivered contrast agent, guided by the operator or the device. The air pressure value achieved during the blowing exercise is displayed in real time on the ultrasound contrast imaging preparation device's screen, allowing determination of whether the target subject's blowing exercise has met the standards based on the real-time displayed air pressure value.

[0145] In some embodiments, the ultrasound contrast imaging preparation device can also be connected to a voice module to provide voice prompts for the actions currently being performed by the device. For example, voice prompts can indicate that the ultrasound contrast imaging preparation device has entered pressure mode, or that the target subject has completed the air-blowing exercise.

[0146] The purging of the delivery components and fluid lines can be performed automatically after the delivery components are confirmed to be installed, or it can be performed after triggering the purging control displayed on the screen of the ultrasound contrast imaging preparation device. The images of the purging process of the delivery components and fluid lines can be static images including the delivery components and fluid lines, or dynamic images of the purging process of the delivery components and fluid lines.

[0147] Images of air, saline solution, and blood being extracted are displayed on the screen of the ultrasound contrast imaging device. These images can be static images including the delivery components, or dynamic images showing the delivery components extracting air, saline solution, and blood.

[0148] The second preset extraction volume is a parameter pre-set in the ultrasound contrast imaging preparation device. Air, saline, and blood each have a corresponding second preset extraction volume.

[0149] In some embodiments, the images of the delivery components and fluid lines being emptied, and the images of air, saline, and blood being extracted, may also show the objects being extracted by each delivery component.

[0150] The repeated extraction and infusion of air, saline, and blood by the delivery component can be performed automatically after the saline, air, and blood have been extracted, or it can be performed after triggering the preparation controls displayed on the screen of the ultrasound contrast imaging preparation device.

[0151] The second preset number of times is a parameter pre-set in the ultrasound contrast agent preparation device. Only when the number of extractions and infusions reaches the second preset number can the contrast agent preparation be ensured to be successful. The first preset number of times can be the same as or different from the second preset number of times. The blowing action of the target object can be achieved through a blowing handle connected to the ultrasound contrast agent preparation device. For example, the target object blows air through the blowing handle connected to the ultrasound contrast agent preparation device, and the blowing handle sends the pressure value reached by the target object to the ultrasound contrast agent preparation device and displays the pressure value reached by the target object in real time. Figure 6 shows images of repeated extraction and infusion of air, saline, and blood in pressure mode, with air pressure detection.

[0152] Images of the repeated extraction and infusion of air, saline, and blood by the delivery assembly are displayed on the screen of the ultrasound contrast imaging device. These images can be static images of the extraction and infusion process or dynamic images of the repeated extraction and infusion.

[0153] In one embodiment, the automatic foaming control method further includes:

[0154] Displays the pressure value currently reached by the air blowing on the target object.

[0155] When the pressure reaches the preset pressure value, the contrast agent is delivered to the target object, and an image of the contrast agent being delivered to the target object is displayed.

[0156] The contrast agent delivery to the target object can be performed automatically after the contrast agent preparation is complete and the pressure reached by the current airflow to the target object reaches a preset pressure value, or it can be performed after triggering the delivery control displayed on the screen of the ultrasound contrast imaging preparation device. The image of the contrast agent delivery to the target object is displayed on the screen of the ultrasound contrast imaging preparation device. This displayed image can be a static image or a dynamic image of the contrast agent delivery to the target object. During the contrast agent delivery process, the ultrasound contrast imaging preparation device also displays the air pressure value of the target object in real time, as shown in Figure 7.

[0157] In this first embodiment, after the ultrasound contrast imaging preparation device has been reset and the target object's air blowing exercise has been completed, images of the delivery component and the liquid path connected to the delivery component undergoing evacuation are displayed. After the delivery component has been evacuated, images of air, saline, and blood being extracted are displayed until the extracted air, saline, and blood each reach their corresponding second preset extraction volume. Images of the delivery component repeatedly extracting and infusing air, saline, and blood are displayed until the number of extractions and infusions reaches the second preset number, thus obtaining the contrast agent. This allows the operator to intuitively see which step of the ultrasound contrast imaging preparation device is currently in pressure mode for contrast agent preparation from the display screen of the ultrasound contrast imaging preparation device.

[0158] In some embodiments, because the target object needs to be inhaled through the air blower handle in pressure mode, and the air blower mask on the handle is a disposable item that needs to be replaced promptly after each use to avoid cross-infection, the air blower mask on the handle needs to be replaced before preparing the contrast agent when the pressure mode trigger control is activated. The air blower mask includes an identification code. By scanning the identification code using the scanning device of the ultrasound contrast imaging preparation apparatus, it is possible to determine whether the replaced air blower mask matches the air blower handle, and also to record the air blower mask used to prevent the replacement mask from having already been used. The identification code includes, but is not limited to, barcodes and QR codes.

[0159] In one embodiment, at least one foaming mode trigger control includes a combined mode trigger control. Automatic contrast agent preparation includes:

[0160] The first contrast agent preparation is performed according to the preparation process in either resting mode or pressure mode to obtain the first-prepared contrast agent. The resting mode preparation process includes resetting, purging, air extraction, saline extraction, blood extraction, and repeated extraction and infusion of the air, saline, and blood. The pressure mode preparation process includes resetting, air blowing exercise, purging, air extraction, saline extraction, blood extraction, and repeated extraction and infusion of the air, saline, and blood.

[0161] The Nth contrast agent is prepared in either resting mode or pressure mode to obtain the Nth prepared contrast agent, where N is greater than or equal to 2.

[0162] The first contrast agent preparation, following either the resting mode or pressure mode preparation process, refers to preparing the contrast agent according to the corresponding resting mode or pressure mode preparation process. Specifically, following the resting mode preparation process, the following steps are performed sequentially: component resetting, emptying the delivery component and fluid lines, air extraction, saline extraction, blood extraction, and repeated extraction and infusion of the extracted air, saline, and blood to obtain the first-prepared contrast agent. Alternatively, following the pressure mode preparation process, the following steps are performed sequentially: component resetting, air blowing exercise, emptying the delivery component and fluid lines, air extraction, saline extraction, blood extraction, and repeated extraction and infusion of the extracted air, saline, and blood to obtain the first-prepared contrast agent.

[0163] "Preparing the Nth contrast agent according to resting mode or pressure mode" means preparing the Nth contrast agent according to the contrast agent preparation process corresponding to resting mode or pressure mode.

[0164] In some embodiments, after the contrast agent is prepared, the ultrasound contrast agent preparation device controls the delivery component to deliver the prepared contrast agent to the target object. After the delivery of the prepared contrast agent is completed, the next contrast agent preparation is performed. For example, after the first contrast agent preparation is performed according to the preparation process in resting mode, the ultrasound contrast agent preparation device controls the delivery component to deliver the prepared contrast agent to the target object. After the delivery of the first contrast agent is completed, the second contrast agent preparation is performed according to the preparation process in resting mode or pressure mode.

[0165] In some embodiments, when the contrast agent is prepared according to a preparation process in resting mode or pressure mode, the display screen will also show images of multiple steps in the preparation process. For example, it may show images of the delivery assembly and fluid lines being emptied, and images of air, saline, and blood being extracted.

[0166] In this first embodiment, after triggering the trigger control corresponding to the integrated mode, the first contrast agent preparation is performed according to the preparation process of rest mode or pressure mode to obtain the first prepared contrast agent. Then, the foaming device is controlled according to rest mode or pressure mode to perform the Nth contrast agent preparation to obtain the Nth prepared contrast agent. When multiple contrast agent preparations are required, it is no longer necessary to jump to the user operation interface and click the trigger control of foaming mode to execute the next contrast agent preparation, saving time and simplifying the process of multiple contrast agent preparations.

[0167] In one embodiment, the automatic foaming control method further includes:

[0168] The prepared contrast agent is delivered to the target object to which the contrast agent is to be delivered, and an image of the contrast agent being delivered to the target object is displayed simultaneously.

[0169] Display and / or broadcast the time elapsed after contrast agent delivery to the target object.

[0170] Based on the duration, it displays contrast images at multiple time points after the contrast agent is delivered to the target object.

[0171] It displays the pressure holding value corresponding to the target object during the delivery of contrast agent, and displays a first indicator characterizing the reliability of the contrast image when the infusion pressure value meets the preset pressure holding conditions.

[0172] The delivery of the contrast agent to the target object can be performed automatically after the contrast agent preparation is complete, or it can be performed after triggering the delivery control displayed on the screen of the ultrasound contrast imaging preparation device. If the delivery of the contrast agent to the target object is performed after triggering the delivery control displayed on the screen of the ultrasound contrast imaging preparation device, then when the contrast agent has been prepared and the delivery control has not been triggered, the delivery component will continuously and repeatedly extract and infuse air, saline, and blood to prevent air bubbles in the contrast agent from disappearing and affecting the imaging effect.

[0173] Images of the contrast agent delivered / injected to the target object are displayed on the screen of the ultrasound contrast imaging preparation device, as shown in Figure 8. The displayed image of the contrast agent delivery to the target object can be a static image or a dynamic image. The dynamic image can be a real-time dynamic image of the contrast agent delivery to the target object or a simulated dynamic image of the contrast agent delivery to the target object.

[0174] The elapsed time after contrast agent delivery refers to the length of time that has elapsed since the contrast agent was delivered. This time can be displayed on the screen of the ultrasound contrast imaging preparation device, as shown in Figure 9. Alternatively, the time can be announced via voice from the voice module installed in the ultrasound contrast imaging preparation device, or it can be both displayed on the screen and announced via voice from the voice module.

[0175] Multiple time points refer to contrast images taken at different points in time after the contrast agent has been delivered to the target object. For example, displaying a contrast image 5 seconds after contrast agent delivery, and displaying a contrast image 10 seconds after contrast agent delivery.

[0176] Contrast images are medical images obtained by using contrast agents to enhance the visibility of specific tissues or organs in medical imaging. Contrast agents help operators see details of blood vessels, organs, or other structures more clearly, improving the accuracy and reliability of diagnoses. Contrast images can be displayed on the screen of an ultrasound contrast imaging device or on a specific medical imaging apparatus. For example, scanning the target object using a medical imaging device at different time points after contrast agent delivery can obtain and display contrast images at multiple time points. Medical imaging equipment includes, but is not limited to, X-ray machines, computed tomography (CT) scanners, magnetic resonance imaging (MRI) machines, digital subtraction angiography (DSA) machines, and ultrasound imaging devices.

[0177] By acquiring angiographic images at multiple different time points, we can observe the blood flow dynamics within the target's blood vessels, assess blood flow velocity and direction, observe the blood perfusion of the target's myocardium / tumor, and quickly assess the location and extent of blood flow obstruction in the target.

[0178] The pressure holding value refers to the gas pressure value of the target object within a preset time period when the contrast agent is delivered according to the pressure mode procedure in pressure mode or integrated mode. The gas pressure value of the target object within the preset time period can also be displayed on the display screen of the ultrasound contrast imaging preparation device, as shown in Figure 10.

[0179] The preset pressure holding condition refers to the preset pressure holding value. Meeting the preset pressure holding condition means that the pressure holding value reaches the preset pressure holding value, or the difference between the pressure holding value and the preset pressure holding value is less than the preset difference.

[0180] A first indicator is displayed on the screen of the ultrasound contrast imaging preparation device to indicate to the operator that the obtained contrast image is reliable. The form of the first indicator includes, but is not limited to, text and images. For example, the reliable contrast image can be indicated by displaying "Image reliable" on the screen, while the reliable contrast image can be indicated by displaying a preset image on the screen to indicate that the contrast image is reliable.

[0181] In some embodiments, if the pressure holding value does not meet the preset pressure holding conditions, the reliability of the obtained contrast image is low, and it is necessary to re-prepare and deliver the contrast agent to the target object until a more reliable contrast image is obtained.

[0182] In some embodiments, the ultrasound contrast-enhancing preparation device also includes a manual delivery control. After the operator triggers the manual delivery control, the ultrasound contrast-enhancing preparation device will not automatically deliver the contrast agent to the target object, but the operator will manually deliver the contrast agent to the target object.

[0183] In some embodiments, when the contrast agent delivery is completed, the display screen of the ultrasound contrast imaging preparation device also includes a continue control and an end control. The continue control is used to continue the contrast agent preparation and delivery according to the next mode, and the end control is used to jump to the user operation interface.

[0184] In this first embodiment, the prepared contrast agent is delivered to the target object to which the contrast agent is to be delivered, and the image of the contrast agent being delivered to the target object is displayed. The time elapsed after the contrast agent is delivered to the target object is displayed and / or broadcast. In this way, the contrast images of the target object at multiple time points after the contrast agent is delivered can be obtained in a timely manner according to the time elapsed. By displaying the pressure value corresponding to the target object during the delivery of the contrast agent, it is convenient to compare the pressure value with the preset pressure conditions, so as to determine whether the obtained contrast images are reliable.

[0185] In one embodiment, a user interface is shown, including:

[0186] In response to the power-on operation, and if the system is already powered on, perform system initialization and power-on self-test.

[0187] Once the system has completed initialization and the power-on self-test is successful, the user login interface will be displayed.

[0188] In response to the login information entry operation triggered on the user login interface, obtain the user's login information.

[0189] The user interface is displayed when the login information is successfully verified.

[0190] The power-on operation can be triggered by the power-on button on the ultrasound contrast imaging preparation device. System initialization refers to the initialization of various modules, components, or functions of the ultrasound contrast imaging preparation device. For example, initializing the system clock, input / output ports, voice module, storage module, QR code module, USB (Universal Serial Bus) host mode, motion control module, and display screen, etc.

[0191] Power-on self-test (POST) mainly refers to the process of checking whether each module, component, or function is functioning properly when the ultrasound contrast imaging preparation device is powered on. For example, during power-on, it checks whether the power supply is over-voltage / under-voltage, whether the EEPROM (Electrically Erasable Programmable Read-Only Memory) / SPI FLASH (Serial Peripheral Interface Flash) is mounted, whether the capacity of the EEPROM / SPI FLASH meets the usage requirements, whether the voice module is mounted, whether the voice memory card is mounted, whether the scanning device is mounted, whether the temperature sensor is mounted, whether the temperature is normal, whether the photoelectric switches and microswitches are malfunctioning, whether the display screen is mounted, and whether the base plate is mounted, etc.

[0192] Each module, component, or function undergoes self-testing / initialization sequentially. This ensures the stability and reliability of the ultrasound contrast imaging preparation device, avoids resource competition caused by simultaneous initialization / power-on self-testing of all modules, components, and functions, and prevents disruption to the normal operation of the ultrasound contrast imaging preparation device. It also makes it easier to pinpoint the specific module, component, or function where the problem occurs when initialization / power-on self-testing occurs.

[0193] Login information refers to the credentials and information used to verify identity and access the ultrasound contrast imaging preparation device. For example, login information may be account information consisting of at least one of numbers, characters, and letters, and password information consisting of at least one of numbers, characters, and letters. It may also be biometric information collected by the information acquisition module of the ultrasound contrast imaging preparation device, wherein biometric information includes, but is not limited to, facial features, iris information, palm print information, fingerprint information, and voice information.

[0194] Login verification is based on the identity information of authorized users of the ultrasound contrast imaging preparation device stored in the identity verification database. Specifically, successful login verification means that the identity verification database contains identity information consistent with the login information. For example, when the login information refers to biometric information, successful verification means that the identity verification database contains identity information identical to the entered biometric information.

[0195] In some embodiments, if the ultrasound contrast imaging preparation device is logged in using account information and password information, when a user logs in, the login interface displayed on the device's screen will first load the account information from the previous login. If the "remember password" option was selected during the previous login, the password information from the previous login will also be loaded. If the "remember password" option was not selected during the previous login, the user needs to enter the password information before triggering the login operation. After triggering the login operation, the ultrasound contrast imaging preparation device will check if the account information is empty, check if the password information is empty, check if the account information is in the authentication database, and check if the entered password information matches the account information. If the checks pass, the display screen of the ultrasound contrast imaging preparation device will display "match successful" and redirect to the user operation interface. If this is the first time logging into the ultrasound contrast imaging preparation device, the user needs to enter account information and password information on the login interface, and if the entered account information and password information match successfully, the user operation interface will be displayed.

[0196] In some embodiments, the user types logging into the ultrasound contrast imaging preparation device include, but are not limited to, a first user, a second user, and a third user. The first user has higher privileges than the second and third users, and the second user has higher privileges than the third user. For example, the third user is a regular user with privileges including operating the foaming service, viewing the foaming service settings, viewing all users and types, and changing the password. The second user has all the privileges of the third user, and can also add / delete third users, view records in the record list, set foaming service parameters, and add / delete second users. The first user has all the privileges of the second user and can also perform system maintenance. The number of registered users (first, second, and third) can also be set to be less than or equal to a preset number. For example, the number of registered users (first, second, and third) is less than or equal to a first preset number, the number of registered users (second, and third) is less than or equal to a third preset number. The first, second, and third preset numbers can be the same or different.

[0197] In this first embodiment, by responding to the login information entry operation triggered on the user login interface, the user's login information is obtained. When the login information is successfully verified, the user operation interface is displayed, which can prevent untrusted users from logging into the ultrasound contrast imaging preparation device and reduce the risk of the ultrasound contrast imaging preparation device.

[0198] In one embodiment, the automatic foaming control method further includes:

[0199] This is in response to the monitoring results of at least one physiological parameter of the target object and the acquisition of timed self-test results. The timed self-test results are obtained by the ultrasound contrast imaging preparation device performing timed self-tests according to a preset self-test cycle.

[0200] If at least two results are abnormal, determine the priority of each abnormal result.

[0201] When the priorities of the abnormal results are inconsistent, an alarm message is output for the result with the highest priority. The alarm message includes at least one of the following: voice prompt, light prompt, and information prompt.

[0202] Physiological parameters include, but are not limited to, heart rate, blood pressure, respiratory rate, blood oxygen saturation, blood oxygen value, body temperature, level of consciousness, skin color and temperature, pain and discomfort, allergic reactions, kidney function, electrocardiogram, hemodynamic parameters, urine output, and electrolyte levels.

[0203] "At least two abnormal results" refers to at least two abnormal monitoring results of physiological parameters, or at least two abnormal timed self-test results, or at least one abnormal monitoring result of physiological parameters and at least one abnormal timed self-test result.

[0204] Abnormal physiological parameter monitoring results refer to actual physiological parameters of the target subject exceeding the standard range. The priority of abnormal monitoring results can be determined based on the degree to which the actual physiological parameters deviate from the standard range, or based on the length of time the actual physiological parameters have deviated from the standard range.

[0205] Abnormal self-test results are usually caused by improper operation or malfunction of the ultrasound contrast imaging preparation device. The priority of abnormal self-test results can be categorized according to the severity of the fault. Specifically, hardware faults that completely render the ultrasound contrast imaging preparation device inoperable, such as power supply failures or motherboard failures, have the highest priority. Faults that affect the main functions of the ultrasound contrast imaging preparation device but do not completely disable it, such as hard drive failures or memory errors, have a relatively high priority. Faults that do not affect the main functions of the ultrasound contrast imaging preparation device but may cause future problems, such as abnormal fan speed or excessive temperature, have a lower priority. When a high-priority abnormal self-test result occurs, the ultrasound contrast imaging preparation device will stop the preparation and delivery of contrast agent, waiting for the fault to be resolved before resuming contrast agent preparation, delivery, or resetting.

[0206] The preset self-test cycle refers to the periodic self-test schedule pre-set in the ultrasound contrast imaging preparation device. For example, the ultrasound contrast imaging preparation device is preset to perform a self-test every 30 minutes. The self-test items according to the preset cycle include, but are not limited to, checking whether each module, component, or function is functioning properly. For example, checking for low / overvoltage power supply, whether the temperature sensor is connected, whether the system temperature is normal, whether the photoelectric switch / microswitch is malfunctioning, and whether the battery capacity / temperature is abnormal. The timed self-tests of each module, component, or function are performed sequentially.

[0207] Alarm prompts of different priorities are represented differently. For example, the highest priority result might be indicated by a flashing red light and an audible alert of "beep-beep-beep-beep-beep-beep-beep-beep". A relatively high priority result might be indicated by a flashing yellow light and an audible alert of "beep-beep-beep". A moderate priority result might be indicated by a solid blue light and an audible alert of "beep", where the flashing frequency of the yellow light can be the same as or lower than that of the red light. Information prompts refer to the display on the ultrasound contrast imaging device's screen showing abnormal results and their priority.

[0208] In some embodiments, the ultrasound contrast imaging preparation device also includes an alarm stop control, which is used to stop and resume alarms. For example, when the ultrasound contrast imaging preparation device outputs an alarm prompt, triggering the alarm stop control will stop the ultrasound contrast imaging preparation device from outputting the alarm prompt. At the same time, the ultrasound contrast imaging preparation device will start a 120-second countdown. After 120 seconds, if the abnormality has not been resolved, the ultrasound contrast imaging preparation device will continue to output the alarm prompt. If the abnormality has been resolved, the ultrasound contrast imaging preparation device will not continue to output the alarm prompt.

[0209] In this first embodiment, when the priorities of the results of each anomaly are inconsistent, an alarm is output for the result with the highest priority. This allows the most important anomalies to be handled first, thereby minimizing potential losses and impacts and reducing risks.

[0210] In one embodiment, the user interface includes a blood pressure monitoring control for blood pressure monitoring. The automatic foaming control method further includes:

[0211] In response to a trigger operation on the blood pressure monitoring control, when the preset measurement mode corresponding to the blood pressure monitoring control is continuous measurement, the target object's blood pressure is continuously measured and the target object's blood pressure value is displayed in real time.

[0212] When the preset measurement mode corresponding to the blood pressure monitoring control is automatic measurement, the target object will be measured multiple times according to the preset measurement cycle of automatic measurement, and the blood pressure value obtained from each measurement will be displayed.

[0213] When the target subject's blood pressure value does not meet the preset blood pressure conditions, a second indicator representing an abnormal blood pressure monitoring result of the target subject is displayed.

[0214] Automatic measurement refers to automatically performing a blood pressure measurement at preset intervals, while continuous measurement refers to uninterrupted blood pressure measurement of the target subject. The preset measurement mode can also be manual. In manual measurement mode, blood pressure monitoring for the target subject automatically ends after one cycle, without requiring manual intervention or resuming. In automatic / continuous measurement mode, stopping blood pressure measurement for the target subject requires manual intervention by the operator.

[0215] The preset blood pressure conditions include pre-set limits for systolic blood pressure, diastolic blood pressure, mean blood pressure, and pulse rate. The measured blood pressure values ​​include systolic blood pressure, diastolic blood pressure, and mean blood pressure, and the target subject's actual pulse rate is also measured. Blood pressure values ​​that do not meet the preset blood pressure conditions refer to one or more situations where the target subject's systolic blood pressure is outside the preset systolic blood pressure limit, diastolic blood pressure is outside the preset diastolic blood pressure limit, or mean blood pressure is outside the preset mean blood pressure limit. Alarm prompts for systolic blood pressure, diastolic blood pressure, mean blood pressure, and pulse rate can be turned on or off. For example, if the systolic blood pressure alarm is turned off, no alarm will be triggered when the target subject's systolic blood pressure is outside the preset systolic blood pressure limit.

[0216] The preset measurement cycle and preset blood pressure conditions are set in advance in the ultrasound contrast imaging preparation device.

[0217] A second indicator is displayed on the screen of the ultrasound contrast imaging preparation device to alert the operator that the target subject's blood pressure monitoring result is abnormal. The form of the second indicator includes, but is not limited to, text and images. For example, an abnormal blood pressure monitoring result can be indicated by displaying "Abnormal blood pressure monitoring result" on the screen, while an abnormal blood pressure monitoring result can be indicated by displaying a preset image on the screen to represent the abnormal blood pressure monitoring result.

[0218] In this first embodiment, when the preset measurement mode corresponding to the blood pressure monitoring control is continuous measurement, the blood pressure of the target object is continuously measured and the blood pressure value of the target object is displayed in real time. When the preset measurement mode corresponding to the blood pressure monitoring control is automatic measurement, the blood pressure of the target object is measured multiple times according to the preset measurement cycle of automatic measurement, and the blood pressure value obtained from each measurement is displayed. This allows the user to always observe the blood pressure value of the target object throughout the entire process of contrast agent preparation and delivery without manually triggering blood pressure monitoring multiple times. This allows for timely implementation of appropriate measures when blood pressure values ​​are abnormal, preventing other diseases from occurring in the target object.

[0219] In one embodiment, the ultrasound contrast imaging preparation device is mounted in a movable trolley. The ultrasound contrast imaging preparation device is detachably connected to the trolley. The user interface includes a rise control for controlling the trolley's ascent, a fall control for controlling the trolley's descent, and a lock control for locking the trolley. The automatic foaming control method further includes:

[0220] In response to a trigger operation on the ascending control, and provided that the trolley locking control is not triggered and the current height of the trolley is less than the maximum permissible height, the trolley is raised to a first height. The first height is less than or equal to the maximum permissible height.

[0221] In response to a trigger action on the descent control, and provided the trolley locking control is not triggered and the trolley's current height is greater than the minimum permissible height, the trolley is lowered to a second height. The second height is greater than or equal to the minimum permissible height.

[0222] When the trolley rises to the first height or falls to the second height, the trolley is prevented from rising or falling in response to a trigger operation on the trolley locking control.

[0223] The trolley locking control, when triggered, can be used to fix the height of the trolley, preventing it from rising or falling. The maximum allowable height refers to the maximum height the trolley can reach when rising. The minimum allowable height refers to the minimum height the trolley can reach when falling.

[0224] The first height can be determined based on the trigger time of the rise control. For example, if the rise control is pressed for 10 seconds, the trolley will rise at a preset speed for 10 seconds, and the height reached after 10 seconds is the first height. The first height can also be determined based on the number of times the rise control is triggered. For example, triggering the rise control once will raise the trolley by a preset fixed height, and triggering it twice will raise it by two preset fixed heights. Similarly, the second height can be determined based on the trigger time of the fall control, and also based on the number of times the fall control is triggered.

[0225] In some embodiments, when the trolley locking control is not triggered and the current height of the trolley is equal to the maximum allowable height, the height of the trolley will not change after the raising control is triggered. At the same time, the display screen of the ultrasound contrast imaging preparation device can also indicate that the trolley has reached the maximum allowable height.

[0226] In some embodiments, when the trolley locking control is not triggered and the current height of the trolley is equal to the minimum allowable height, the height of the trolley will not change after the descent control is triggered. At the same time, the display screen of the ultrasound contrast imaging preparation device can also indicate that the trolley has reached the minimum allowable height.

[0227] In some embodiments, when the trolley locking control is triggered, the height of the trolley will not change after the raising / lowering control is triggered, and the display screen of the ultrasound contrast imaging preparation device can also indicate that the trolley is locked.

[0228] In some embodiments, when the trolley locking control is not triggered and the distance between the current height of the trolley and the minimum allowable height is less than or equal to a preset distance, the display screen of the ultrasound contrast imaging preparation device can also indicate that the distance between the height of the trolley and the minimum allowable height is less than or equal to a preset distance.

[0229] In this first embodiment, by responding to a trigger operation on the up control, and when the trolley locking control is not triggered and the current height of the trolley is less than the maximum allowable height, the trolley is raised to a first height. Similarly, by responding to a trigger operation on the down control, and when the trolley locking control is not triggered and the current height of the trolley is greater than the minimum allowable height, the trolley is lowered to a second height. This ensures that the trolley is only allowed to move up or down when it is not locked, avoiding the risk of accidental movement. It also prevents the trolley from operating beyond its safe range, reducing the risk of damage to the trolley and the ultrasound contrast imaging preparation device, and preventing damage to the target object during trolley movement.

[0230] In one embodiment, the user interface includes at least one of a record list control, a parameter setting control, and a consumable replacement control; the method further includes:

[0231] In response to a triggered action on the record list control, the record list is displayed. The record list includes at least one of the following records.

[0232] The test records include timed self-test results, power-on self-test results, and contrast images in various modes.

[0233] Consumables records, including details of consumables used in each mode.

[0234] Operation records, including the operation log of the ultrasound contrast imaging preparation device.

[0235] Blood pressure records, including the time and results of blood pressure monitoring.

[0236] Alarm logs, including alarm time and alarm type.

[0237] In response to a trigger action on the parameter setting control, the parameter setting interface is displayed. The parameter setting interface includes at least one of the following controls:

[0238] Blood pressure parameter control: used to set preset blood pressure conditions, preset measurement cycle, blood pressure alarm switch status, and pressure unit for various types of target objects.

[0239] Foaming parameter control: Used to set blood drawing speed, equipment type, injection method for each foaming mode, contrast agent preparation speed, contrast agent injection speed, holding time, number of repeated preparations, repeated preparation interval, restore default value, consumable model, and air content.

[0240] Air blower handle parameter control: Used to set the preset pressure value for the target object.

[0241] Time parameter control: Used to set the time and the format of the displayed time.

[0242] Language control: Used to set the language.

[0243] Brightness and volume controls: Used to set brightness and volume.

[0244] System maintenance controls: Used for positioning and resetting the injection component, and establishing connections with interconnected electronic devices. Displays system software version information.

[0245] Push-in component: Used to push the delivery component.

[0246] The foaming parameter control is used to set the blood drawing speed, equipment type, injection method under each foaming mode, contrast agent preparation speed, contrast agent injection speed, pressure holding time, number of repeated preparations, repeated preparation interval, restore default value, consumable model, and air content. The foaming parameter setting interface corresponding to the foaming parameter control is shown in Figure 11, and the blood pressure parameter setting interface corresponding to the blood pressure parameter setting control is shown in Figure 12.

[0247] The language control can be used to set the language of the ultrasound contrast imaging preparation device. For example, setting the language displayed on the ultrasound contrast imaging preparation device to English. The brightness and volume controls can be used to adjust the brightness and volume of the ultrasound contrast imaging preparation device. The consumable replacement control is used to control the replacement of consumables. For example, controlling the replacement of the air mask on the air handle. Connectivity-enabled electronic devices can be Bluetooth-enabled devices.

[0248] A bolus assembly is a component used to actuate the delivery assembly. For example, when the delivery assembly contains the prepared contrast agent, controlling the bolus assembly to push the delivery assembly allows the contrast agent to be delivered to the target object. The bolus assembly includes, but is not limited to, motors, pneumatic drive assemblies, and spring drive assemblies. During the actuation process, the bolus assembly can be driven at high speed throughout, or initially at low speed followed by high speed. The time required for actuation depends on the speed of the bolus assembly and the amount of contrast agent. For example, when the bolus assembly pushes the delivery assembly at high speed throughout to deliver 10 ml of contrast agent to the target object, the time required is 2 seconds.

[0249] In some embodiments, in response to a trigger operation on the time parameter control, a time parameter setting interface is displayed. Time information is entered into the interface, and if the time information is correct, it is written to the system's RTC (Real-Time Clock) to complete the time parameter setting. The time information mainly includes year, month, day, and hour. If the time information is entered incorrectly, the ultrasound contrast imaging device will also display a prompt indicating an error.

[0250] This application also provides an application scenario in which the above-described automatic foaming control method is applied. Specifically, the automatic foaming control method is applied in this scenario as follows:

[0251] When the ultrasound contrast imaging preparation device is not powered on, the operator briefly presses the power switch. The microcontroller then takes over the power input control, achieving a soft start of the device. After the device is powered on, the display screen enters the startup interface and sequentially initializes the system clock, input / output ports, voice module, storage module, QR code module, USB host mode, motion control module, and display screen. After system initialization, the device sequentially checks for over / under voltage, whether the EEPROM (Electrically Erasable Programmable Read-Only Memory) / SPI FLASH (Serial Peripheral Interface Flash) is mounted, whether the capacity of the EEPROM / SPI FLASH meets the usage requirements, whether the voice module is mounted, whether the voice memory card is mounted, whether the scanning device is mounted, whether the temperature sensor is mounted, whether the temperature is normal, whether the photoelectric switch and micro switch are abnormal, whether the display screen is mounted, and whether the base plate is mounted.

[0252] After the ultrasound contrast imaging preparation device completes system initialization and its power-on self-test is successful, it displays the user login interface. When logging in via biometric information, the device's information acquisition module collects the operator's biometric information and matches it with identity information in the identity verification database. If the database contains an identity matching the entered biometric information, the user interface is displayed on the device's screen, as shown in Figure 13. The user interface includes a record list control, parameter setting control, consumable replacement control, resting mode trigger control, pressure mode trigger control, comprehensive mode trigger control, blood pressure monitoring control, rise control, fall control, and lock control. When logging in via account and password, the login interface on the device's screen first loads the account information from the previous login. If the "remember password" option was selected during the previous login, the password will also be loaded. If the "remember password" option was not selected, the password must be entered before the login process is triggered. After the login operation is triggered, the ultrasound contrast imaging preparation device will check whether the account information is empty, whether the password information is empty, whether the account information is in the identity verification database, and whether the entered password information matches the account information. If the identity information matches successfully, the display screen of the ultrasound contrast imaging preparation device will jump to the user operation interface.

[0253] The operator triggers the trigger control corresponding to the resting mode on the user interface. The ultrasound contrast imaging preparation device responds to the trigger operation of the trigger control for the resting mode. After all components have been reset, it displays an image of the delivery component and the fluid path connected to the delivery component being emptied. After the delivery component and the fluid path have been emptied, it displays an image of air, saline, and blood being extracted. It displays an image of the delivery component repeatedly extracting and infusing air, saline, and blood until the number of extractions and infusions reaches the first preset number, thus obtaining the contrast agent. When the prepared contrast agent is delivered to the target object, an image of the contrast agent being delivered to the target object is displayed simultaneously.

[0254] The operator triggers the trigger control corresponding to the pressure mode on the user interface. The ultrasound contrast preparation device responds to the trigger operation of the trigger control for the pressure mode. After all components have been reset and the target object to be delivered contrast agent has passed the air blowing exercise, the device displays an image of the delivery component and the liquid path connected to the delivery component being emptied. After the delivery component and the liquid path have been emptied, the device displays images of air, saline, and blood being drawn. The device displays images of the delivery component repeatedly drawing and infusing air, saline, and blood until the number of drawing and infusions reaches the second preset number. The device displays the pressure value reached by the target object during air blowing, and the contrast agent is obtained. When the pressure value reaches the preset pressure value, the prepared contrast agent is delivered to the target object, and an image of the contrast agent being delivered to the target object is displayed.

[0255] The operator triggers the trigger control corresponding to the comprehensive mode on the user interface. The ultrasound contrast preparation device responds to the trigger operation of the trigger control for the comprehensive mode, performs the first contrast agent preparation according to the preparation process of rest mode or pressure mode, and delivers the prepared contrast agent to the target object. It then performs the Nth contrast agent preparation according to rest mode or pressure mode and delivers the prepared contrast agent to the target object, where N is greater than or equal to 2.

[0256] The display screen of the ultrasound contrast imaging preparation device can also display images of the contrast agent being delivered to the target object during the delivery process. The device can display the elapsed time since the contrast agent was delivered to the target object, and / or announce the elapsed time. Based on the elapsed time, the device displays contrast images at multiple time points after the contrast agent delivery, shows the corresponding holding pressure values ​​for the target object during the delivery process, and displays a first indicator characterizing the reliability of the contrast image when the holding pressure values ​​meet preset holding pressure conditions.

[0257] During the preparation and delivery of the contrast agent, the ultrasound contrast imaging device monitors the physiological parameters of the target subject, obtaining monitoring results for at least one physiological parameter. The device also performs periodic self-checks according to a preset self-check cycle, obtaining timed self-check results. If at least two results are abnormal, the device determines the priority of each abnormal result. If the priorities of the abnormal results are inconsistent, the device outputs an alarm prompt for the result with the highest priority. The alarm prompt includes at least one of the following: voice prompt, light prompt, and information prompt.

[0258] When monitoring the physiological parameters of a target subject, if the required physiological parameter is the target subject's blood pressure, the ultrasound contrast imaging preparation device responds to the trigger operation of the blood pressure monitoring control. When the preset measurement mode corresponding to the blood pressure monitoring control is continuous measurement, it continuously measures the target subject's blood pressure and displays the blood pressure value in real time. When the preset measurement mode corresponding to the blood pressure monitoring control is automatic measurement, it performs multiple blood pressure measurements on the target subject according to the preset automatic measurement cycle and displays the blood pressure value obtained from each measurement. If the target subject's blood pressure value does not meet the preset blood pressure conditions, a second indicator representing an abnormal blood pressure monitoring result is displayed.

[0259] During the preparation and delivery of the contrast agent, if the current height of the trolley is low, the ultrasound contrast preparation device will respond to the trigger operation of the rise control and, if the trolley locking control is not triggered and the current height of the trolley is less than the maximum allowable height, raise the trolley to the first height. If the current height of the trolley is high, the ultrasound contrast preparation device will respond to the trigger operation of the fall control and, if the trolley locking control is not triggered and the current height of the trolley is greater than the minimum allowable height, lower the trolley to the second height.

[0260] After triggering the record list control of the ultrasound contrast imaging preparation device, the device will display the record list in response to the trigger operation. The record list includes test records, consumable records, operation records, blood pressure records, and alarm records. After triggering the parameter setting control of the ultrasound contrast imaging preparation device, the device will display the parameter setting interface in response to the trigger operation. The parameter setting interface includes blood pressure parameter controls, foaming parameter controls, air blowing handle parameter controls, time parameter controls, language controls, brightness and volume controls, system maintenance controls, and injection components.
