[0083] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0084] The automatic foaming control method provided by the embodiments of the present application can be applied to an application environment as shown in Figure 1 . The ultrasonic contrast medium preparation device 102 is detachably connected with the trolley 104, and the ultrasonic contrast medium preparation device 102 is assembled in the trolley 104 which is allowed to move. The ultrasonic contrast medium preparation device 102 triggers instructions in the form of interface interaction to automatically perform the preparation of the contrast medium. The ultrasonic contrast medium preparation device 102 displays a user operation interface. The user operation interface includes a trigger control of at least one foaming mode. The ultrasonic contrast medium preparation device 102 automatically prepares the contrast medium in response to the trigger operation of the trigger control of at least one foaming mode.

[0085] In an embodiment, as shown in Figure 2 , an automatic foaming control method is provided. The method is described by taking the ultrasonic contrast medium preparation device 102 in Figure 1 as an example, which includes the following steps:

[0086] S202, a user operation interface is displayed. The user operation interface includes a trigger control of at least one foaming mode.

[0087] The trigger control of the foaming mode is a control for controlling the ultrasonic contrast preparation device to automatically prepare the contrast medium. The foaming mode includes at least one of a resting mode, a pressure mode, and a comprehensive mode. The resting mode is a foaming mode without target object blowing and direct delivery after successful preparation of the contrast medium. The pressure mode is a foaming mode in which the contrast medium is delivered after the target object blowing reaches the standard. The comprehensive mode is a mode combining multiple foaming modes. For example, the comprehensive mode can be a combination of the resting mode and the pressure mode, a combination of multiple resting modes, or a combination of multiple pressure modes.

[0088] The ultrasonic contrast preparation device includes a display screen, and the user operation interface is displayed in the display screen of the ultrasonic contrast preparation device. The display screen can be a touch screen that allows the user to directly operate on the screen surface by a finger or a touch pen.

[0089] S204, in response to the triggering operation of the trigger control of at least one foaming mode, automatically preparing the contrast medium.

[0090] The trigger control of the foaming mode is a control for controlling the ultrasonic contrast preparation device to automatically prepare the contrast medium. The foaming mode includes at least one of a resting mode, a pressure mode, and a comprehensive mode. The resting mode is a foaming mode without target object blowing and direct delivery after successful preparation of the contrast medium. The pressure mode is a foaming mode in which the contrast medium is delivered after the target object blowing reaches the standard. The comprehensive mode is a mode combining multiple foaming modes. For example, the comprehensive mode can be a combination of the resting mode and the pressure mode, a combination of multiple resting modes, or a combination of multiple pressure modes.

[0091] In some embodiments, if the user operation interface includes trigger controls of multiple foaming modes, only one trigger control corresponding to one foaming mode can be triggered at a time.

[0092] In some embodiments, the ultrasonic contrast preparation device further includes an emergency stop control. If any situation affecting the preparation of the contrast medium occurs during the execution of the foaming business by the ultrasonic contrast preparation device, the emergency stop control is triggered, and the preparation of the contrast medium can be stopped.

[0093] In the above-mentioned automatic control foaming method, the user operation interface is displayed; the user operation interface includes a trigger control of at least one foaming mode; and in response to the triggering operation of the trigger control of at least one foaming mode, the contrast medium is automatically prepared. On the one hand, this method can reduce the workload and improve the efficiency, and on the other hand, since the preparation process of the contrast medium is automatically controlled, the deviation that may occur during manual operation is avoided, and the consistency of the quality of the contrast medium is ensured. In addition, since each step of preparing the contrast medium is automatically controlled, the speed and quality of foaming can be accurately controlled, and the situation that the quality of the prepared contrast medium is poor due to too fast or too slow foaming speed and does not meet the medical requirements can be avoided.

[0094] In one embodiment, the trigger control of at least one foaming mode includes a trigger control of the resting mode. The automatic preparation of the contrast medium includes:

[0095] In the case of resetting, an image of the delivery assembly and the liquid path connected with the delivery assembly being subjected to the emptying process is displayed. The delivery assembly is an assembly loaded in the ultrasound contrast agent preparation device.

[0096] In the case of the delivery assembly and the liquid path being emptied, an image of air, normal saline and blood being extracted is displayed until the extracted air, normal saline and blood respectively reach a corresponding first preset extraction amount.

[0097] An image of the delivery assembly repeatedly extracting and infusing air, normal saline and blood is displayed until the number of times of extraction and infusion reaches a first preset number of times, and the contrast agent is obtained.

[0098] The resetting refers to each assembly in the ultrasound contrast agent preparation device returning to an initial state or a default setting. The resetting of the ultrasound contrast agent preparation device can be performed after the last preparation of the contrast agent is completed, after the trigger control for triggering the resting mode is triggered, or both.

[0099] The delivery assembly refers to an assembly for delivering a fluid, such as a liquid or a gas, from one location to another. The delivery assembly includes but is not limited to a syringe, a catheter.

[0100] The first preset extraction amount is a parameter preset in the ultrasound contrast agent preparation device. The air, the normal saline and the blood each have a corresponding first preset extraction amount.

[0101] In some embodiments, the ultrasound contrast agent preparation device can also be loaded with a voice module to voice prompt the action currently performed by the ultrasound contrast agent preparation device. For example, the ultrasound contrast agent preparation device has entered the resting mode is voice prompted, the delivery assembly and the liquid path are being subjected to the emptying process is voice prompted, the delivery assembly is extracting air, normal saline and blood is voice prompted, the ultrasound contrast agent preparation device is currently preparing the contrast agent is voice prompted, and the preparation of the contrast agent is completed is voice prompted.

[0102] In some embodiments, since the contrast agent needs to be prepared using the delivery assembly, if the delivery assembly is not installed in the ultrasound contrast agent preparation device, the user will be prompted to install the delivery assembly in time before the image of the emptying process is displayed. The way of prompting the user can be one or more of voice prompting by the voice module loaded in the ultrasound contrast agent preparation device, text prompting by the display screen of the ultrasound contrast agent preparation device, and light prompting by the ultrasound contrast agent preparation device. In this way, it can be ensured that the ultrasound contrast agent preparation device is preparing the contrast agent under the condition that the delivery assembly has been installed, so as to ensure the smooth preparation of the contrast agent.

[0103] The emptying action of the delivery assembly and the liquid path connected with the delivery assembly can be automatically performed after it is determined that the delivery assembly is installed, or can be performed after a control for emptying included in a display screen of the ultrasound contrast medium preparation device is triggered.

[0104] Images of the extracted air, physiological saline and blood are displayed in the display screen of the ultrasound contrast medium preparation device. The displayed images of the extracted air, physiological saline and blood can be static images including the delivery assembly, or dynamic images of the delivery assembly extracting the air, physiological saline and blood. The dynamic images can be real-time dynamic images of the extracted air, physiological saline and blood, or simulated dynamic images of the delivery assembly extracting the air, physiological saline and blood.

[0105] In some embodiments, in the displayed images of the delivery assembly and the liquid path performing the emptying process, and the images of the extracted air, physiological saline and blood, the objects extracted by the respective delivery assemblies can also be displayed. For example, the object extracted by the delivery assembly A is air, and the object extracted by the delivery assembly B is physiological saline, then in the displayed images, the delivery assembly A can be displayed as extracting air, and the delivery assembly B can be displayed as extracting physiological saline (sodium chloride solution). As Figure 3 shows the images of the delivery assembly performing the emptying process in the resting mode, and Figure 4 shows the images of the extracted air, physiological saline and blood.

[0106] The repeated extracting and infusing actions of the delivery assembly on the air, physiological saline and blood can be automatically performed after the physiological saline, air and blood are extracted, or can be performed after a control for preparation included in the display screen of the ultrasound contrast medium preparation device is triggered.

[0107] The first preset number is a parameter pre-set in the ultrasound contrast medium preparation device, and only when the number of the extracting and infusing reaches the first preset number, it can be ensured that the preparation of the contrast medium is successful.

[0108] The images of the repeated extracting and infusing actions of the delivery assembly on the air, physiological saline and blood are displayed in the display screen of the ultrasound contrast medium preparation device, as Figure 5 shown. The displayed images of the repeated extracting and infusing actions of the delivery assembly on the air, physiological saline and blood can be static images of the extracting and infusing, or dynamic images of the repeated extracting and infusing. The dynamic images can be real-time dynamic images of the repeated extracting and infusing of the delivery assembly on the air, physiological saline and blood, or simulated dynamic images of the repeated extracting and infusing of the delivery assembly on the air, physiological saline and blood.

[0109] In some embodiments, if the extracted physiological saline sample is insufficient to prepare the contrast agent, the preparation of the contrast agent is stopped, and the user is prompted that the physiological saline sample is insufficient until the extracted physiological saline sample is sufficient to prepare the contrast agent. The sample amount of the physiological saline can be determined by the diameter of the liquid path of the ultrasonic contrast preparation device, the flow rate of the physiological saline, and the flow time. Alternatively, when the air bubble sensor of the ultrasonic contrast preparation device detects air bubbles in the liquid, the size and frequency of the air bubbles are measured to calculate the proportion of air, and then the proportion of air is used to calculate the proportion of physiological saline to determine the sample amount of the extracted physiological saline.

[0110] In some embodiments, when the blood is extracted, the blood oxygen sensor is also used to detect the blood oxygen value of the collected blood. If the blood oxygen value is not within the normal range, the extraction of the blood is stopped, and an alarm prompt is output to prompt the operator that the blood is abnormal.

[0111] In this embodiment, when the ultrasonic contrast preparation device is reset, an image of the delivery assembly and the liquid path connected to the delivery assembly is displayed for emptying treatment. When the delivery assembly is emptied, an image of the extraction of air, physiological saline, and blood is displayed until the extracted air, physiological saline, and blood each reach a corresponding first preset extraction amount. An image of the repeated extraction and infusion of air, physiological saline, and blood by the delivery assembly is displayed until the number of extractions and infusions reaches a first preset number, and the contrast agent is obtained. In this way, the operator can directly view from the display screen of the ultrasonic contrast preparation device which step of preparing the contrast agent in the resting mode the ultrasonic contrast preparation device is currently in.

[0112] In one embodiment, the at least one foaming mode trigger control includes a pressure mode trigger control. The automatic preparation of the contrast agent includes:

[0113] When the reset is completed and the target object to be delivered with the contrast agent passes the blowing exercise, an image of the delivery assembly and the liquid path connected to the delivery assembly is displayed for emptying treatment. The delivery assembly is a component loaded in the ultrasonic contrast preparation device.

[0114] When the delivery assembly and the liquid path are emptied, an image of the extraction of air, physiological saline, and blood is displayed until the extracted air, physiological saline, and blood each reach a corresponding second preset extraction amount.

[0115] An image of the repeated extraction and infusion of air, physiological saline, and blood by the delivery assembly is displayed until the number of extractions and infusions reaches a second preset number, and the contrast agent is obtained.

[0116] The reset refers to the recovery of each component in the ultrasound contrast preparation device to the initial state or default setting. The blowing exercise refers to the blowing practice of the target object to be delivered with the contrast agent under the guidance of the operator or the device. The air pressure value reached by the blowing exercise is also displayed in real time on the display screen of the ultrasound contrast preparation device, so that whether the blowing exercise of the target object meets the standard can be determined according to the real-time displayed air pressure value.

[0117] In some embodiments, the ultrasound contrast preparation device can also be connected with a voice module to prompt the current action performed by the ultrasound contrast preparation device through voice. For example, the ultrasound contrast preparation device has entered the pressure mode through voice, and the blowing exercise of the target object meets the standard through voice.

[0118] The emptying action of the delivery assembly and the liquid path can be automatically performed after determining that the delivery assembly is installed, or can be performed after triggering the emptying control displayed on the display screen of the ultrasound contrast preparation device. The image of the delivery assembly and the liquid path performing the emptying process can be a static image including the delivery assembly and the liquid path, or a dynamic image of the delivery assembly and the liquid path performing the emptying process.

[0119] The images of the extracted air, physiological saline and blood are displayed on the display screen of the ultrasound contrast preparation device. The displayed images of the extracted air, physiological saline and blood can be static images including the delivery assembly, or dynamic images of the delivery assembly extracting air, physiological saline and blood.

[0120] The second preset extraction amount is a parameter preset in the ultrasound contrast preparation device. The air, physiological saline and blood each have a corresponding second preset extraction amount.

[0121] In some embodiments, in the image of the delivery assembly and the liquid path performing the emptying process, and the image of the extracted air, physiological saline and blood, the objects extracted by each delivery assembly can also be displayed.

[0122] The repeated extraction and infusion of the delivery assembly to the air, physiological saline and blood can be automatically performed after the physiological saline, air and blood are extracted, or can be performed after triggering the preparation control displayed on the display screen of the ultrasound contrast preparation device.

[0123] The second preset number of times is a parameter pre-set in the ultrasound contrast agent preparation device. Only when the number of times of extraction and infusion reaches the second preset number of times, the preparation of the contrast agent can 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 realized through a blowing handle connected to the ultrasound contrast agent preparation device. For example, the target object blows through the blowing handle connected to the ultrasound contrast agent preparation device. The blowing handle sends the pressure value reached by the blowing of the target object to the ultrasound contrast agent preparation device, and displays the pressure value reached by the blowing of the target object in real time. Figure 6 Figures showing repeated extraction and infusion of air, normal saline and blood, and air pressure detection under the pressure mode.

[0124] The images of repeated extraction and infusion of air, normal saline and blood by the delivery assembly are displayed on the display screen of the ultrasound contrast agent preparation device. The displayed images of repeated extraction and infusion of air, normal saline and blood by the delivery assembly can be static images of extraction and infusion, or dynamic images of repeated extraction and infusion.

[0125] In one embodiment, the automatic foaming control method further comprises:

[0126] The current pressure value reached by the blowing of the target object is displayed.

[0127] When the pressure value reaches the preset pressure value, the contrast agent is delivered to the target object, and an image of delivering the contrast agent to the target object is displayed.

[0128] The action of delivering the contrast agent to the target object can be automatically performed after the preparation of the contrast agent is completed and the current pressure value reached by the blowing of the target object reaches the preset pressure value, or can be performed after a delivery control displayed on the display screen of the ultrasound contrast agent preparation device is triggered. The image of delivering the contrast agent to the target object is displayed on the display screen of the ultrasound contrast agent preparation device. The displayed image of delivering the contrast agent to the target object can be a static image of delivering the contrast agent to the target object, or a dynamic image of delivering the contrast agent to the target object. During the delivery of the contrast agent, the ultrasound contrast agent preparation device also displays the air pressure value of the target object in real time, as shown in Figure 7

[0129] ​In this embodiment, when the reset of the ultrasonic contrast agent preparation device is completed and the target object meets the blowing exercise standard, the image of the delivery assembly and the liquid path connected with the delivery assembly for emptying treatment is displayed, and when the delivery assembly is emptied, the images of the extracted air, physiological saline and blood are displayed until the extracted air, physiological saline and blood respectively reach the corresponding second preset extraction amount, the images of the repeated extraction and infusion of the delivery assembly to the air, physiological saline and blood are displayed until the number of extraction and infusion reaches the second preset number, and the contrast agent is obtained. In this way, the operator can directly observe from the display screen of the ultrasonic contrast agent preparation device which step of preparing the contrast agent in the pressure mode the ultrasonic contrast agent preparation device is currently in.

[0130] In some embodiments, since the target object needs to blow through the blowing handle in the pressure mode, the blowing mask on the blowing handle is a disposable tool which needs to be replaced in time after being used once to avoid cross infection. Therefore, the blowing mask on the blowing handle needs to be replaced before the contrast agent is prepared when the trigger control of the pressure mode is triggered. The blowing mask includes an identification code, which is scanned by the scanning device of the ultrasonic contrast agent preparation device. On the one hand, it can be judged whether the replaced blowing mask is matched with the blowing handle, and on the other hand, it can record the used blowing mask to avoid the replaced blowing mask being used.

[0131] In one embodiment, the trigger control of at least one foaming mode includes the trigger control of the comprehensive mode. The automatic preparation of the contrast agent includes:

[0132] The first contrast agent preparation is performed according to the preparation process of the resting mode or the pressure mode to obtain the first prepared contrast agent. The preparation process of the resting mode includes reset, emptying, extraction of air, extraction of physiological saline, extraction of blood, and repeated extraction and infusion of air, physiological saline and blood. The preparation process of the pressure mode includes reset, blowing exercise, emptying, extraction of air, extraction of physiological saline, extraction of blood, and repeated extraction and infusion of air, physiological saline and blood.

[0133] The Nth contrast agent preparation is performed according to the resting mode or the pressure mode to obtain the Nth prepared contrast agent, and N is greater than or equal to 2.

[0134] The first contrast agent preparation according to the resting mode or the stress mode preparation procedure refers to the first preparation of the contrast agent according to the corresponding contrast agent preparation procedure of the resting mode or the corresponding contrast agent preparation procedure of the stress mode. Specifically, according to the resting mode preparation procedure, the assembly reset, the delivery assembly and the liquid path emptying, the air extraction, the saline extraction, the blood extraction, and the repeated extraction and infusion of the extracted air, saline and blood are sequentially performed to obtain the first prepared contrast agent, or according to the stress mode preparation procedure, the assembly reset, the air blowing exercise, the delivery assembly and the liquid path emptying, the air extraction, the saline extraction, the blood extraction, and the repeated extraction and infusion of the extracted air, saline and blood are sequentially performed to obtain the first prepared contrast agent.

[0135] The Nth contrast agent preparation according to the resting mode or the stress mode refers to the Nth preparation of the contrast agent according to the corresponding contrast agent preparation procedure of the resting mode or the corresponding contrast agent preparation procedure of the stress mode.

[0136] In some embodiments, after the preparation of the contrast agent, the ultrasonic contrast preparation device controls the delivery assembly to deliver the prepared contrast agent to the target object, and after the delivery of the prepared contrast agent is completed, the next preparation of the contrast agent is performed. For example, after the first preparation of the contrast agent according to the resting mode preparation procedure obtains the first prepared contrast agent, the ultrasonic contrast preparation device controls the delivery assembly to deliver the prepared contrast agent to the target object, and after the delivery of the first prepared contrast agent is completed, the second preparation of the contrast agent is performed according to the resting mode or the stress mode preparation procedure.

[0137] In some embodiments, the display screen also displays images of multiple steps in the preparation procedure when the preparation of the contrast agent is performed according to the resting mode or the stress mode preparation procedure. For example, images of the delivery assembly and the liquid path emptying, the air extraction, the saline extraction, and the blood extraction are displayed.

[0138] In this embodiment, after triggering the trigger control corresponding to the comprehensive mode, the first preparation of the contrast agent is performed according to the resting mode or the stress mode preparation procedure to obtain the first prepared contrast agent, and the Nth preparation of the contrast agent is performed according to the resting mode or the stress mode to obtain the Nth prepared contrast agent. When multiple preparations of the contrast agent are required, the next preparation of the contrast agent can be performed without jumping to the user operation interface by clicking the trigger control of the foaming mode, saving time and simplifying the process of multiple preparations of the contrast agent.

[0139] In one embodiment, the automatic foaming control method further comprises:

[0140] The prepared contrast agent is delivered to a target object to which the contrast agent is to be delivered, and an image of the delivery of the contrast agent to the target object is displayed.

[0141] A time length elapsed after the delivery of the contrast agent to the target object is displayed and / or announced.

[0142] According to the time length, contrast images at multiple time nodes after the delivery of the contrast agent to the target object are displayed.

[0143] A pressure maintaining value corresponding to the target object during the delivery of the contrast agent is displayed, and a first identifier representing that a contrast image is reliable is displayed when an infusion pressure value meets a preset pressure maintaining condition.

[0144] The action of delivering the contrast agent to the target object can be automatically performed after the preparation of the contrast agent is completed, or can be performed after a delivery control displayed on a display screen of the ultrasound contrast preparation device is triggered. If the action of delivering the contrast agent to the target object is performed after the delivery control displayed on the display screen of the ultrasound contrast preparation device is triggered, the delivery assembly repeatedly extracts and infuses air, normal saline and blood continuously when the contrast agent has been prepared and the delivery control is not triggered, so as to prevent the disappearance of air bubbles in the contrast agent and affect the contrast effect.

[0145] The image of delivering / injecting the contrast agent to the target object is displayed on the display screen of the ultrasound contrast preparation device, as shown in FIG. 5. Figure 8 The displayed image of delivering the contrast agent to the target object can be a static image of delivering the contrast agent to the target object, or can be a dynamic image of delivering the contrast agent to the target object. The dynamic image can be a real-time dynamic image of delivering the contrast agent to the target object, or can be a simulated dynamic image of delivering the contrast agent to the target object.

[0146] The time length elapsed after the delivery of the contrast agent refers to the length of time elapsed after the delivery of the contrast agent. The time length can be displayed on the display screen of the ultrasound contrast preparation device, as shown in FIG. 6. Figure 9 The time length can also be announced by a voice module loaded in the ultrasound contrast preparation device, and the time length can be displayed on the display screen of the ultrasound contrast preparation device and announced by the voice module loaded in the ultrasound contrast preparation device.

[0147] The multiple time nodes refer to contrast images at different time points after the delivery of the contrast agent to the target object. For example, a contrast image 5 seconds after the delivery of the contrast agent is displayed, and a contrast image 10 seconds after the delivery of the contrast agent is displayed.

[0148] The contrast image refers to a medical image obtained by using a contrast agent to enhance the visibility of a specific tissue or organ in medical imaging. The contrast agent can help the operator to see the details of blood vessels, organs or other structures more clearly, improve the accuracy and reliability of diagnosis. The contrast image can be displayed on the display screen of the ultrasound contrast preparation device, or can be displayed in a specific medical imaging device. For example, after the contrast agent is delivered, the target object is scanned at different time nodes using a medical imaging device, and then a plurality of contrast images at different time nodes can be obtained and displayed. The medical imaging device includes but is not limited to an X-ray machine, a computed tomography device, a magnetic resonance imaging device, a digital subtraction angiography device, and an ultrasound imaging device.

[0149] By obtaining contrast images at different time nodes, the blood flow dynamics in the blood vessels of the target object can be observed, the blood flow velocity and direction can be evaluated, the blood perfusion of the myocardium / tumor of the target object can be observed, and the position and degree of blood flow obstruction of the target object can be quickly evaluated.

[0150] The holding pressure value refers to the air pressure value of the target object within a preset time length when the contrast agent is delivered according to the pressure mode or the comprehensive mode. The air pressure value of the target object within the preset time length can also be displayed on the display screen of the ultrasound contrast preparation device, as shown in Figure 10 .

[0151] The preset holding pressure condition refers to the preset holding pressure value. The preset holding pressure condition is satisfied when the holding pressure value reaches the preset holding pressure value, or the difference between the holding pressure value and the preset holding pressure value is less than a preset difference value.

[0152] The first identifier is displayed on the display screen of the ultrasound contrast preparation device to prompt the operator that the obtained contrast image is reliable. The form of the first identifier includes but is not limited to text and image. For example, the text representing that the contrast image is reliable can be displayed as “image reliable” on the display screen, and the image representing that the contrast image is reliable can be a preset image displayed on the display screen to indicate that the contrast image is reliable.

[0153] In some embodiments, if the holding pressure value does not satisfy the preset holding pressure condition, the reliability of the obtained contrast image is low, and the contrast agent needs to be re-prepared and delivered to the target object until a more reliable contrast image is obtained.

[0154] In some embodiments, the ultrasound contrast preparation device further comprises a manual delivery control. After the operator triggers the manual delivery control, the ultrasound contrast preparation device does not automatically deliver the contrast agent to the target object, but manually delivers the contrast agent to the target object by the operator.

[0155] In some embodiments, the display screen of the ultrasound contrast preparation device further comprises a continue control and an end control when the contrast agent delivery is completed, 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.

[0156] In this embodiment, by delivering the prepared contrast agent to the target object to which the contrast agent is to be delivered, displaying the image of delivering the contrast agent to the target object, and displaying and / or announcing the time length after the target object delivers the contrast agent, the contrast images at multiple time nodes after the target object delivers the contrast agent can be obtained in time according to the time length, and by displaying the corresponding pressure maintaining value of the target object in the process of delivering the contrast agent, the pressure maintaining value can be compared with the preset pressure maintaining condition, so as to determine whether the obtained contrast image is reliable.

[0157] In one embodiment, the user operation interface is displayed, and the user operation interface comprises:

[0158] In response to a power-on operation, and in the case of having been powered on, system initialization and power-on self-test are performed.

[0159] In the case of completing system initialization and no error in the power-on self-test, a user login interface is displayed.

[0160] In response to a login information entry operation triggered in the user login interface, login information of the user is obtained.

[0161] In the case of successful login information verification, the user operation interface is displayed.

[0162] The power-on operation can be triggered by a power-on button of the ultrasound contrast preparation device. The system initialization refers to initializing each module, or component, or function of the ultrasound contrast preparation device. For example, initializing a system clock, initializing an input / output port, initializing a voice module, initializing a storage module, initializing a two-dimensional code module, initializing a universal serial bus (USB) host mode, initializing a motion control module, and initializing a display screen.

[0163] The power-on self-test mainly refers to detecting whether each module, or component, or function can be normally used when the ultrasonic contrast medium preparation device is powered on. For example, detecting whether the power supply is overvoltage / low voltage, detecting whether EEPROM (Electrically Erasable Programmable Read-Only Memory) / SPI FLASH (Serial Peripheral Interface Flash) is mounted, detecting whether the capacity of EEPROM / SPI FLASH meets the use requirements, detecting whether the voice module is mounted, detecting whether the voice storage card is mounted, detecting whether the scanning device is mounted, detecting whether the temperature sensor is mounted, detecting whether the temperature is normal, detecting whether the photoelectric switch and the micro switch are abnormal, detecting whether the display screen is mounted, detecting whether the bottom plate is mounted, and the like.

[0164] The self-test / initialization of each module, or component, or function is performed in sequence, which can ensure the stability and reliability of the ultrasonic contrast medium preparation device, avoid resource competition caused by simultaneous initialization / simultaneous power-on self-test of all modules, components, and functions, affect the normal operation of the ultrasonic contrast medium preparation device, and also facilitate locating the specific module, or specific component, or specific function where the problem is located when the initialization / power-on self-test has a problem.

[0165] The login information refers to credentials and information for verifying identity and accessing the ultrasonic contrast medium preparation device. For example, the login information can be account information composed of at least one of numbers, characters, and letters and password information composed of at least one of numbers, characters, and letters, and can be biological feature information collected by an information collection module of the ultrasonic contrast medium preparation device, wherein the biological feature information includes but is not limited to facial features, iris information, palm print information, fingerprint information, and voice information.

[0166] The verification of the login information is implemented based on the identity information of the authorized user of the ultrasonic contrast medium preparation device stored in the identity verification database. Specifically, the successful verification of the login information can be understood as that the identity information consistent with the login information is stored in the identity verification database. For example, when the login information refers to biological feature information, the successful verification can be understood as that the identity information consistent with the input biological feature information is stored in the identity verification database.

[0167] In some embodiments, if the ultrasound contrast preparation device is logged in through account information and password information, when a user logs in the ultrasound contrast preparation device, the login interface displayed on the display screen of the ultrasound contrast preparation device will first load the account information of the last login. If the password information of the last login was checked, the password information of the last login will also be loaded. If the password information of the last login was not checked, the password information needs to be input, and then the login operation is triggered. After triggering the login operation, the ultrasound contrast preparation device checks whether the account information is empty, checks whether the password information is empty, detects whether the account information is in the identity verification database, and detects whether the input password information matches the account information. If the check is passed, the ultrasound contrast preparation device displays the matching pass on the display screen and jumps to the user operation interface. If the ultrasound contrast preparation device is logged in for the first time, the account information and the password information need to be input in the user login interface, and the user operation interface is displayed if the input account information and password information are matched.

[0168] In some embodiments, the user types who log in the ultrasound contrast preparation device include but are not limited to a first user, a second user, and a third user, wherein the first user has higher permissions than the second user and the third user, and the second user has higher permissions than the third user. For example, the third user is a general user, and the permissions of the third user include operating a foaming service, viewing the setting parameters of the foaming service, viewing all users and types, and modifying a password. The second user includes all the permissions of the third user, and can also add / delete the third user, view each record in a record list, set the parameters of the foaming service, and add / delete the second user. The first user includes all the permissions of the second user, and can also perform system maintenance. The registration number of the first user, the second user, and the third user can also be set to be less than or equal to a preset registration number. For example, the registration number of the first user is less than or equal to a first preset registration number, the registration number of the second user is less than or equal to a second preset registration number, and the registration number of the third user is less than or equal to a third preset registration number. The first preset registration number, the second preset registration number, and the third preset registration number can be set to be consistent or inconsistent.

[0169] In this embodiment, by responding to the login information input operation triggered in the user login interface, the login information of the user is obtained, and when the login information verification is successful, the user operation interface is displayed, which can avoid logging in the ultrasound contrast preparation device by untrusted users and reduce the risk of the ultrasound contrast preparation device.

[0170] In one embodiment, the automatic foaming control method further includes:

[0171] The acquisition operation of the timing self-check result is in response to the monitoring result of the at least one physiological parameter of the target object and the timing self-check result.

[0172] In the case that the at least two results are abnormal, the priority of each abnormal result is determined.

[0173] In the case that the priorities of the abnormal results are inconsistent, an alarm prompt for the result with the highest priority is output. The alarm prompt includes at least one of a voice prompt, a light prompt, and an information prompt.

[0174] The physiological parameters include, but are not limited to, heart rate, blood pressure, respiratory rate, blood oxygen saturation, blood oxygen value, body temperature, consciousness state, skin color and temperature, pain and discomfort, allergic reaction, kidney function, electrocardiogram, blood flow dynamics parameter, urine volume, and electrolyte level.

[0175] The at least two abnormal results refer to abnormal monitoring results of at least two physiological parameters, or abnormal timing self-check results of at least two physiological parameters, or abnormal monitoring results of at least one physiological parameter and abnormal timing self-check results of at least one physiological parameter.

[0176] The abnormal monitoring result of the physiological parameter refers to that the actual physiological parameter of the target object exceeds the standard range. The priority of the abnormal monitoring result can be determined according to the degree of deviation of the actual physiological parameter from the standard range, or can be determined according to the time length of deviation of the actual physiological parameter from the standard range.

[0177] The abnormal timing self-check result is usually caused by non-standard operation or failure of the ultrasound contrast agent preparation device. The priority of the abnormal timing self-check result can be divided according to the severity of the failure. Specifically, a hardware failure that can cause the ultrasound contrast agent preparation device to completely fail to operate, such as a power failure or a mainboard failure, has the highest priority. A failure that can affect the main functions of the ultrasound contrast agent preparation device, such as a hard disk failure or a memory error, has a higher priority. A failure that does not affect the main functions of the ultrasound contrast agent preparation device, such as abnormal fan speed or high temperature, has a lower priority. In the case of an abnormal self-check result with a higher priority, the ultrasound contrast agent preparation device will stop the preparation and delivery of the contrast agent and wait for the abnormality to be eliminated before continuing the preparation or delivery of the contrast agent or resetting.

[0178] The preset self-checking period refers to a period of timing self-checking preset in the ultrasound contrast agent preparation device. For example, the ultrasound contrast agent preparation device is preset to perform self-checking once every 30 minutes. The items of self-checking according to the preset period include but are not limited to detecting whether each module, or component, or function can be normally used. For example, detecting whether the power supply is low voltage / overvoltage, detecting whether the temperature sensor is mounted, detecting whether the system temperature is normal, detecting whether the photoelectric switch / micro switch is abnormal, detecting whether the battery capacity / battery temperature is abnormal. The timing self-checking of each module, or component, or function is performed in turn.

[0179] The representation forms of the alarm prompts of different priorities are different. For example, the light prompt of the result with the highest priority can be red light flashing, and the sound prompt can be "beep-beep-beep-beep-beep-beep-beep-beep". The light prompt of the result with higher priority can be yellow light flashing, and the sound prompt can be "beep-beep-beep". The light prompt of the result with general priority can be blue light always on, and the sound prompt can be "beep". The flashing frequency of the yellow light can be consistent with that of the red light, or lower than that of the red light. The information prompt refers to displaying the abnormal result and the priority of the abnormal result on the display screen of the ultrasound contrast agent preparation device.

[0180] In some embodiments, the ultrasound contrast agent preparation device further comprises an alarm suspension control for stopping the alarm and resuming the alarm. For example, when the ultrasound contrast agent preparation device outputs the alarm prompt, the alarm suspension control is triggered, and the ultrasound contrast agent preparation device stops outputting the alarm prompt. At the same time, the ultrasound contrast agent preparation device starts a 120s countdown. After 120s, if the abnormality has not been solved, the ultrasound contrast agent preparation device will continue to output the alarm prompt. If the abnormality has been solved, the ultrasound contrast agent preparation device will not continue to output the alarm prompt.

[0181] In this embodiment, when the priorities of the results of different abnormalities are inconsistent, the alarm prompt for the result with the highest priority is outputted, so that the most important abnormality can be processed first, so as to minimize the potential loss and impact and reduce the risk.

[0182] In one embodiment, the user operation interface comprises a blood pressure monitoring control for blood pressure monitoring. The automatic foaming control method further comprises:

[0183] In response to the triggering operation of the blood pressure monitoring control, 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.

[0184] When the preset measurement mode corresponding to the blood pressure monitoring control is automatic measurement, multiple blood pressure measurements are performed on the target object according to a preset measurement period of automatic measurement, and the blood pressure values obtained in each measurement are displayed.

[0185] When the blood pressure value of the target object does not meet the preset blood pressure condition, a second identifier representing that the blood pressure monitoring result of the target object is abnormal is displayed.

[0186] The automatic measurement refers to automatically performing a blood pressure measurement once at a preset measurement period, and the continuous measurement refers to continuously measuring the blood pressure of the target object. The preset measurement mode can also be manual measurement. When the preset measurement mode is manual measurement, the blood pressure monitoring of the target object automatically ends after being executed once, without the need for manual interruption or further execution. When the preset measurement mode is automatic measurement / continuous measurement, the blood pressure measurement of the target object needs to be manually operated by the operator.

[0187] The preset blood pressure condition includes a pre-set systolic pressure limit value, a diastolic pressure limit value, a mean pressure limit value, and a pulse rate limit value. The measured blood pressure values include systolic pressure, diastolic pressure, and mean pressure, and the actual pulse rate of the target object is also measured. The blood pressure value not meeting the preset blood pressure condition refers to one or more of the following situations: the systolic pressure of the target object is outside the pre-set systolic pressure limit value, the diastolic pressure of the target object is outside the diastolic pressure limit value, and the mean pressure of the target object is outside the mean pressure limit value. The alarm prompt for systolic pressure, diastolic pressure, mean pressure, and pulse rate can also be selected to be turned on or off. For example, if the alarm prompt for systolic pressure is turned off, no alarm prompt will be given when the systolic pressure of the target object is outside the pre-set systolic pressure limit value.

[0188] The preset measurement period and the preset blood pressure condition are pre-set in the ultrasonic contrast preparation device.

[0189] The second identifier is displayed on the display screen of the ultrasonic contrast preparation device to prompt the operator that the blood pressure monitoring result of the target object is abnormal. The form of the second identifier includes but is not limited to text and image. For example, the way to represent the blood pressure monitoring result as abnormal in text is to display “blood pressure monitoring result is abnormal” on the display screen, and the way to represent the blood pressure monitoring result as abnormal in image is to display a pre-set image on the display screen to indicate that the blood pressure monitoring result is abnormal.

[0190] In this 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 period of automatic measurement, and the blood pressure value obtained each time is displayed. In this way, the user can always observe the blood pressure value of the target object during the entire preparation and delivery of the contrast agent without manually triggering the blood pressure monitoring multiple times. Therefore, when the blood pressure value is abnormal, appropriate measures can be taken in time to avoid other symptoms of the target object.

[0191] In one embodiment, the ultrasound contrast preparation device is arranged in a trolley that allows movement, the ultrasound contrast preparation device is detachably connected with the trolley, and the user operation interface includes an ascending control for controlling the trolley to ascend, a descending control for controlling the trolley to descend, and a locking control for locking the trolley. The automatic foaming control method further includes:

[0192] In response to a triggering operation of the ascending control, and when the trolley locking control is not triggered and the current height of the trolley is less than the maximum allowed height, the trolley is controlled to ascend to a first height. The first height is less than or equal to the maximum allowed height.

[0193] In response to a triggering operation of the descending control, and when the trolley locking control is not triggered and the current height of the trolley is greater than the minimum allowed height, the trolley is controlled to descend to a second height. The second height is greater than or equal to the minimum allowed height.

[0194] When the trolley ascends to the first height or descends to the second height, in response to a triggering operation of the trolley locking control, the trolley is prohibited from ascending or descending.

[0195] The trolley locking control, when triggered, can be used to fix the height of the trolley and prohibit the trolley from ascending or descending. The maximum allowed height refers to the maximum height that the trolley can ascend to. The minimum allowed height refers to the minimum height that the trolley can descend to.

[0196] The first height can be determined according to the triggering time of the ascending control. For example, the trolley is controlled to ascend for 10 seconds at a pre-set ascending speed when the ascending control is pressed for 10 seconds, and the height reached after 10 seconds of ascending is the first height. The first height can also be determined according to the number of times the ascending control is triggered. For example, the trolley is controlled to ascend by a pre-set fixed height when the ascending control is triggered once, and the trolley is controlled to ascend by two pre-set fixed heights when the ascending control is triggered twice. Similarly, the second height can also be determined according to the triggering time of the descending control, and can also be determined according to the number of times the descending control is triggered.

[0197] 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 lifting control is triggered, and the display screen of the ultrasound contrast preparation device can also prompt that the trolley has reached the maximum allowable height.

[0198] 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 lowering control is triggered, and the display screen of the ultrasound contrast preparation device can also prompt that the trolley has reached the minimum allowable height.

[0199] In some embodiments, when the trolley locking control is triggered, the height of the trolley will not change after the lifting control / lowering control is triggered, and the display screen of the ultrasound contrast preparation device can also prompt that the trolley is locked.

[0200] 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 the preset distance, the display screen of the ultrasound contrast preparation device can also prompt that the distance between the height of the trolley and the minimum allowable height is less than or equal to the preset distance.

[0201] In this embodiment, by controlling the trolley to rise to the first height in response to the triggering operation of the lifting control and when the trolley locking control is not triggered and the current height of the trolley is less than the maximum allowable height, and controlling the trolley to lower to the second height in response to the triggering operation of the lowering control and when the trolley locking control is not triggered and the current height of the trolley is greater than the minimum allowable height, it can be ensured that the trolley is only allowed to be lifted and lowered when it is unlocked, avoiding the risk of accidental movement, and also preventing the trolley from running out of the safe range, reducing the risk of damage to the trolley and the ultrasound contrast preparation device, and avoiding damage to the target object during movement of the trolley.

[0202] In one embodiment, the user operation interface includes at least one of a record list control, a parameter setting control, and a consumable replacement control, and the method further includes:

[0203] In response to a triggering operation of the record list control, a record list is displayed. The record list includes at least one of the following records.

[0204] The detected records include self-test results, power-on self-test results, and contrast images in various modes.

[0205] The consumable records include details of consumables used in various modes.

[0206] The operation records include operation logs of the ultrasound contrast preparation device.

[0207] Blood pressure records, including blood pressure monitoring time and blood pressure monitoring results.

[0208] Alarm records, including alarm time and alarm type.

[0209] In response to a triggering operation on the parameter setting control, a parameter setting interface is displayed. The parameter setting interface includes at least one of the following controls:

[0210] Blood pressure parameter control: used to set the preset blood pressure condition, preset measurement period, blood pressure alarm switch state, and pressure unit of each type of target object.

[0211] Foaming parameter control: used to set the blood extraction speed, device type, injection method under each foaming mode, contrast agent preparation speed, contrast agent injection speed, pressure holding time, repeated preparation number, repeated preparation interval time, default value recovery, consumable model, and air content.

[0212] Air blowing handle parameter control: used to set the preset pressure value for the target object.

[0213] Time parameter control: used to set the time and display time format.

[0214] Language control: used to set the language.

[0215] Brightness and volume control: used to set the brightness and volume.

[0216] System maintenance control: used to position the push injection assembly, reset the system, and establish a connection with an electronic device having an interconnection function. The software version information of the system is displayed.

[0217] Push injection assembly: used to push the delivery assembly.

[0218] The foaming parameter control is used to set the blood extraction speed, device type, injection method under each foaming mode, contrast agent preparation speed, contrast agent injection speed, pressure holding time, repeated preparation number, repeated preparation interval time, default value recovery, consumable model, and air content. The foaming parameter setting interface corresponding to the foaming parameter control is as shown in Figure 11 The blood pressure parameter setting control corresponds to the blood pressure parameter setting interface as shown in Figure 12 .

[0219] The language control can be used to set the language of the ultrasound contrast preparation device. For example, the language displayed by the ultrasound contrast preparation device is set to English. The brightness and volume control can be used to adjust the brightness and volume of the ultrasound contrast preparation device. The consumable replacement control is used to control the replacement of consumables. For example, the replacement of the air blowing mask on the air blowing handle is controlled. The electronic device having an interconnection function can be a device having a Bluetooth function.

[0220] The push injection assembly is an assembly for pushing the delivery assembly. For example, when the prepared contrast agent is loaded in the delivery assembly, the contrast agent loaded in the delivery assembly can be delivered to the target object by controlling the push injection assembly to push the delivery assembly. The push injection assembly includes but is not limited to a motor, a pneumatic drive assembly, and a spring drive assembly. During the process of pushing by the push injection assembly, the pushing mode mainly includes full-speed pushing and low-speed pushing first and then high-speed pushing. The time required for pushing is determined according to the speed of the push injection assembly and the amount of the contrast agent. For example, when the push injection assembly pushes the delivery assembly at full speed to deliver 10 ml of the contrast agent to the target object, the time required is 2 s.

[0221] In some embodiments, in response to a triggering operation on the time parameter control, a time parameter setting interface is displayed, time information is input in the time parameter interface, and in the case that the time information is input correctly, the input time information is written into the RTC (Real-Time Clock) of the system to complete the setting of the time parameter. The time information mainly includes year, month, day, hour, etc. In the case that the time information is input incorrectly, the ultrasonic contrast agent preparation device will also prompt that the time information is input incorrectly.

[0222] The application further provides an application scenario, which applies the automatic foaming control method.

[0223] Specifically, the automatic foaming control method is applied in the application scenario as follows:

[0224] When the ultrasonic contrast agent preparation device is not powered on, the operator short-presses the power switch, and the microcontroller takes over the power input control to realize the soft start of the ultrasonic contrast agent preparation device. After the ultrasonic contrast agent preparation device is started, the display screen enters the start-up interface, and the system clock, input and output ports, voice module, storage module, two-dimensional code module, USB host mode, motion control module, display screen, etc. of the ultrasonic contrast agent preparation device are initialized in turn. After the system initialization is completed, the ultrasonic contrast agent preparation device detects whether the power is overvoltage / low 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 use requirements, whether the voice module is mounted, whether the voice storage 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 the micro switch are abnormal, whether the display screen is mounted, whether the bottom plate is mounted, etc.

[0225] 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 against 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. Figure 13 As shown. 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 the ultrasound contrast imaging preparation device requires login with account and password information, 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 password information must be entered 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 identity verification database, and check if the entered password information matches the account information. If the identity information matches successfully, the ultrasound contrast imaging preparation device's screen will jump to the user interface.

[0226] 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.
