[0083] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0084] The automatic foaming control method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the ultrasound contrast preparation device 102 is detachably connected to the trolley 104, and the ultrasound contrast preparation device 102 is assembled in the trolley 104 that allows movement. The ultrasound contrast preparation device 102 triggers instructions through interface interaction to automatically perform the preparation of contrast agent. The ultrasound contrast preparation device 102 displays a user operation interface. The user operation interface includes a trigger control for at least one bubble mode. The ultrasound contrast preparation device 102 automatically prepares the contrast agent in response to the trigger operation of the trigger control for at least one bubble mode.
[0085] In one embodiment, Figure 2 As shown, an automatic foaming control method is provided, which is applied to Figure 1 The ultrasound contrast preparation device 102 in the embodiment is used as an example to illustrate the method, which includes the following steps:
[0086] S202, displaying a user operation interface. The user operation interface includes at least one trigger control of a foaming mode.
[0087] Among them, the trigger control of the bubble mode is a control for controlling the ultrasonic contrast preparation device to automatically prepare the contrast agent. The bubble mode includes at least one of the rest mode, the pressure mode, and the comprehensive mode. The rest mode is a bubble mode in which the contrast agent can be directly delivered after the successful preparation without blowing the target object. The pressure mode is a bubble mode in which the contrast agent is delivered only after the target object blows to the standard. The comprehensive mode is a mode that combines multiple bubble modes. For example, the comprehensive mode can be a combination of the rest mode and the pressure mode, or a combination of multiple rest modes, or a combination of multiple pressure modes.
[0088] The ultrasound contrast preparation device includes a display screen, and the user operation interface is displayed on the display screen of the ultrasound contrast preparation device. The display screen can be a touch screen that allows the user to operate directly on the screen surface through a finger or a stylus.
[0089] S204 , automatically preparing contrast agent in response to a trigger operation of a trigger control for at least one bubbling mode.
[0090] The trigger control for triggering a foaming mode executes a contrast agent preparation process corresponding to the foaming mode. For example, the user operation interface includes a trigger control corresponding to the foaming mode of the resting mode. After the trigger control of the resting mode is triggered, the ultrasound contrast preparation device prepares the contrast agent according to the process of the resting mode.
[0091] In some embodiments, if the user operation interface includes trigger controls for multiple foaming modes, when the controls are triggered, only the trigger control corresponding to one foaming mode can be triggered at a time.
[0092] In some embodiments, the ultrasound contrast preparation device further includes an emergency stop control. If any situation that affects the preparation of the contrast agent occurs during the foaming process of the ultrasound contrast preparation device, the emergency stop control is triggered, and the preparation of the contrast agent can be terminated.
[0093] In the above-mentioned automatic control foaming method, a user operation interface is displayed; the user operation interface includes a trigger control for at least one foaming mode; in response to the trigger operation of the trigger control for at least one foaming mode, the contrast agent is automatically prepared. On the one hand, this method can reduce the workload and improve efficiency. On the other hand, since the process of preparing the contrast agent is automatically controlled, the deviation that may occur during manual operation is avoided, and the consistency of the contrast agent quality is ensured. In addition, since each step of preparing the contrast agent is automatically controlled, the foaming speed and foaming quality can be accurately controlled to avoid the situation where the foaming speed is too fast or too slow, resulting in poor quality of the prepared contrast agent, which does not meet medical requirements.
[0094] In one embodiment, at least one trigger control of the bubbling mode includes a trigger control of the resting mode. Automatically preparing a contrast agent, comprising:
[0095] When the resetting is completed, an image of the delivery component and the liquid path connected to the delivery component being emptied is displayed. The delivery component is a component loaded in the ultrasound contrast preparation device.
[0096] When the delivery assembly and the fluid path are completely emptied, images of the extracted air, saline, and blood are displayed until the extracted air, saline, and blood each reach a corresponding first preset extraction volume.
[0097] An image showing the delivery component repeatedly extracting and infusing air, saline and blood until the number of extractions and infusions reaches a first preset number to obtain a contrast agent.
[0098] Resetting refers to the components in the ultrasound contrast preparation device returning to their initial state or default settings. The ultrasound contrast preparation device can be reset after the last contrast agent preparation is completed, or after the trigger control of the rest mode is triggered. It can also be reset once after the last contrast agent preparation is completed, and once after the trigger control of the rest mode is triggered.
[0099] A delivery component is a component used to deliver a fluid, such as a liquid or a gas, from one location to another. Delivery components include, but are not limited to, syringes and catheters.
[0100] The first preset extraction volume is a parameter pre-set in the ultrasound contrast preparation device. Air, physiological saline, and blood all have a corresponding first preset extraction volume.
[0101] In some embodiments, the ultrasound contrast preparation device may also be equipped with a voice module to prompt the ultrasound contrast preparation device through voice to indicate the action currently being performed. For example, a voice prompt is provided to indicate that the ultrasound contrast preparation device has entered a resting mode, a voice prompt is provided to indicate that the delivery component and the liquid path are being emptied, a voice prompt is provided to indicate that the delivery component is extracting air, saline and blood, a voice prompt is provided to indicate that the ultrasound contrast preparation device is currently preparing a contrast agent, and a voice prompt is provided to indicate that the preparation of the contrast agent is complete.
[0102] In some embodiments, since the contrast agent needs to be prepared using a delivery component, if the delivery component is not installed in the ultrasound contrast preparation device, the user will be prompted to install the delivery component in time before the image of the emptying process is displayed. The method of prompting the user can be one or more of voice prompts through a voice module loaded on the ultrasound contrast preparation device, text prompts through the display screen of the ultrasound contrast preparation device, and light prompts through the ultrasound contrast preparation device. This can ensure that the ultrasound contrast preparation device prepares the contrast agent when the delivery component is already installed, so as to ensure that the preparation of the contrast agent proceeds smoothly.
[0103] The emptying action of the delivery component and the fluid path connected to the delivery component can be automatically performed after it is determined that the delivery component is installed, or it can be performed after triggering the emptying control included in the display screen of the ultrasound contrast preparation device.
[0104] The images of the extracted air, saline and blood are displayed on the display screen of the ultrasound contrast preparation device. The displayed images of the extracted air, saline and blood may be a static image of the delivery component, or a dynamic image of the delivery component extracting air, saline and blood. The dynamic image may be a real-time dynamic image of the extracted air, saline and blood, or a simulated dynamic image of the delivery component extracting air, saline and blood.
[0105] In some embodiments, in the displayed images of the delivery components and the liquid circuit being emptied, and the images of extracting air, saline, and blood, the objects extracted by each delivery component can also be displayed. For example, if the object extracted by delivery component A is air, and the object extracted by delivery component B is saline, then in the displayed images, it can be shown that delivery component A extracts air, and delivery component B extracts saline (sodium chloride solution). Figure 3 The image shown is an image of the emptying process in resting mode. Figure 4 Shown are images of the extraction of air, saline, and blood.
[0106] The action of the delivery component to repeatedly extract and infuse air, saline and blood can be performed automatically after the extraction of saline, air and blood is completed, or it can be performed after triggering the preparation controls included in the display screen of the ultrasound contrast preparation device.
[0107] The first preset number of times is a parameter pre-set in the ultrasound contrast preparation device. Only when the number of extractions and infusions reaches the first preset number of times can the successful preparation of the contrast agent be ensured.
[0108] The image of the repeated extraction and infusion of air, saline and blood by the delivery component is displayed on the display screen of the ultrasound contrast preparation device, such as Figure 5 The image of the delivery component repeatedly extracting and infusing air, saline and blood can be a static image of the extraction and infusion, or a dynamic image of the repeated extraction and infusion. The dynamic image can be a real-time dynamic image of the delivery component repeatedly extracting and infusing air, saline and blood, or a simulated dynamic image of the delivery component repeatedly extracting and infusing air, saline and blood.
[0109] In some embodiments, if the amount of saline sample extracted is insufficient to prepare contrast agent, the contrast agent preparation task will be terminated and the user will be prompted that the amount of saline sample is insufficient until the amount of saline sample extracted is sufficient to prepare contrast agent. The amount of saline sample can be determined by the diameter of the liquid path for extracting saline by the ultrasound contrast preparation device, the flow rate of saline, and the circulation time. When the bubble sensor of the ultrasound contrast preparation device detects bubbles in the liquid, the size and frequency of these bubbles are measured to calculate the proportion of air, and then the proportion of saline is calculated based on the proportion of air, so as to determine the amount of saline sample extracted.
[0110] In some embodiments, when blood is drawn, a 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, blood drawing will be stopped and an alarm will be output to inform the operator of blood abnormalities.
[0111] In this embodiment, when the ultrasound contrast preparation device is reset, an image of the emptying process of the delivery component and the liquid path connected to the delivery component is displayed; when the delivery component is emptied, an image of the extraction of air, saline and blood is displayed until the extracted air, saline and blood each reach the corresponding first preset extraction volume; an image of the delivery component repeatedly extracting and infusing air, saline and blood is displayed until the number of extractions and infusions reaches the first preset number to obtain contrast agent. This allows the operator to intuitively see from the display screen of the ultrasound contrast preparation device which step of preparing the contrast agent in the resting mode the ultrasound contrast preparation device is currently in.
[0112] In one embodiment, at least one of the trigger controls for the foaming mode includes a trigger control for the pressure mode. Automatically preparing a contrast agent, comprising:
[0113] When the resetting is completed and the target object to be delivered contrast medium has passed the insufflation drill, an image of the delivery component and the liquid path connected to the delivery component being emptied is displayed. The delivery component is a component loaded in the ultrasound contrast preparation device.
[0114] When the delivery assembly and the fluid path are completely emptied, images of the extracted air, saline, and blood are displayed until the extracted air, saline, and blood each reach a corresponding second preset extraction volume.
[0115] An image showing the delivery component repeatedly extracting and infusing air, saline and blood until the number of extractions and infusions reaches a second preset number to obtain a contrast agent.
[0116] Reset refers to the restoration of the components in the ultrasound contrast preparation device to the initial state or default setting. Insufflation drill refers to the insufflation drill performed by the target object to be delivered with contrast agent under the guidance of the operator or the device. The air pressure value achieved by the insufflation drill will also be displayed in real time on the display screen of the ultrasound contrast preparation device, so that it can be determined whether the insufflation drill of the target object meets the standard based on the air pressure value displayed in real time.
[0117] In some embodiments, the ultrasound contrast preparation device may also be connected to a voice module to provide a voice prompt of the action currently being performed by the ultrasound contrast preparation device, for example, providing a voice prompt that the ultrasound contrast preparation device has entered a pressure mode, or providing a voice prompt that the target object has reached the target for the insufflation exercise.
[0118] The emptying action of the delivery component and the fluid path can be automatically performed after the delivery component 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 component and the fluid path being emptied can be a static image including the delivery component and the fluid path, or can be a dynamic image of the delivery component and the fluid path being emptied.
[0119] The images of the extracted air, saline and blood are displayed on the display screen of the ultrasound contrast preparation device. The displayed images of the extracted air, saline and blood can be a static image including the conveying component, or a dynamic image of the conveying component extracting air, saline and blood.
[0120] The second preset extraction volume is a parameter pre-set in the ultrasound contrast preparation device. Air, physiological saline, and blood each have a corresponding second preset extraction volume.
[0121] In some embodiments, in the images of the emptying process of the transport components and the liquid circuits, and in the images of extracting air, saline, and blood, the objects extracted by each transport component can also be displayed.
[0122] The action of the delivery component to repeatedly extract and infuse air, saline and blood can be performed automatically after the extraction of saline, air and blood is completed, or it can be performed after triggering the preparation control displayed on the display screen of the ultrasound contrast preparation device.
[0123] The second preset number is a parameter pre-set in the ultrasound contrast preparation device. Only when the number of extractions and infusions reaches the second preset number can the contrast agent preparation be successfully ensured. The first preset number may be the same as or different from the second preset number. Among them, the blowing action of the target object can be achieved by a blowing handle connected to the ultrasound contrast preparation device. For example, the target object is blown through the blowing handle connected to the ultrasound contrast preparation device, and the blowing handle sends the pressure value reached by the target object's blowing to the ultrasound contrast preparation device, and displays the pressure value reached by the target object's blowing in real time. Figure 6 The images show repeated extraction and infusion of air, saline, and blood in pressure mode, and pressure detection.
[0124] The image of the delivery component repeatedly extracting and infusing air, saline and blood is displayed on the display screen of the ultrasound contrast preparation device. The displayed image of the delivery component repeatedly extracting and infusing air, saline and blood can be a static image of the extraction and infusion, or a dynamic image of the repeated extraction and infusion.
[0125] In one embodiment, the automatic foaming control method further comprises:
[0126] Displays the current pressure value reached by the target object.
[0127] When the pressure value reaches a preset pressure value, the contrast agent is delivered to the target object, and an image of the contrast agent delivered to the target object is displayed.
[0128] The action of delivering contrast agent to the target object can be automatically executed after the preparation of the contrast agent is completed and the pressure value currently reached by the blowing of the target object reaches the preset pressure value, or it can be executed after triggering the delivery control displayed on the display screen of the ultrasound contrast preparation device. The image of delivering contrast agent to the target object is displayed on the display screen of the ultrasound contrast preparation device. The displayed image of delivering contrast agent to the target object can be a static image of delivering contrast agent to the target object, or it can be a dynamic image of delivering contrast agent to the target object. During the process of delivering contrast agent, the ultrasound contrast preparation device will also display the air pressure value of the target object in real time, such as Figure 7 shown.
[0129] In this embodiment, when the ultrasound contrast preparation device is reset and the target object's blowing drill meets the standard, an image of the delivery component and the liquid circuit connected to the delivery component being emptied is displayed; when the delivery component is emptied, an image of extracting air, saline and blood is displayed until the extracted air, saline and blood each reach the corresponding second preset extraction volume; an image of the delivery component repeatedly extracting and infusing air, saline and blood is displayed until the number of extractions and infusions reaches the second preset number to obtain a contrast agent. This allows the operator to intuitively see from the display screen of the ultrasound contrast preparation device which step of preparing the contrast agent in the pressure mode the ultrasound contrast preparation device is currently at.
[0130] In some embodiments, since the target object in the pressure mode needs to be blown through the blowing handle, and the blowing mask on the blowing handle is a disposable device, it needs to be replaced in time after one use to avoid cross infection. Therefore, when the trigger control of the pressure mode is triggered, the blowing mask on the blowing handle needs to be replaced before preparing the contrast agent. Among them, the blowing mask includes an identification code. By scanning the identification code with a scanning device of the ultrasound contrast preparation device, on the one hand, it can be determined whether the replaced blowing mask matches the blowing handle, and on the other hand, the used blowing mask can be recorded to avoid the replaced blowing mask being used. The identification code includes but is not limited to a barcode and a QR code.
[0131] In one embodiment, at least one trigger control of the bubbling mode includes a trigger control of the integrated mode. Automatically prepare contrast agent, comprising:
[0132] The first contrast medium preparation is performed according to the preparation process of the rest mode or the pressure mode to obtain the first prepared contrast medium. The preparation process of the rest mode includes resetting, emptying, extracting air, extracting saline, extracting blood, and repeatedly extracting and infusing air, saline, and blood. The preparation process of the pressure mode includes resetting, blowing drill, emptying, extracting air, extracting saline, extracting blood, and repeatedly extracting and infusing air, saline, and blood.
[0133] The contrast agent is prepared for the Nth time in a rest mode or a pressure mode to obtain the contrast agent prepared for the Nth time, where N is greater than or equal to 2.
[0134] Among them, preparing the contrast agent for the first time according to the preparation process of the rest mode or the pressure mode means that the contrast agent is prepared for the first time according to the contrast agent preparation process corresponding to the rest mode or the contrast agent preparation process corresponding to the pressure mode. Specifically, according to the preparation process of the rest mode, the components are reset, the conveying components and the liquid circuit are emptied, air is extracted, saline is extracted, blood is extracted, and the extracted air, saline and blood are repeatedly extracted and infused to obtain the contrast agent prepared for the first time, or according to the preparation process of the pressure mode, the components are reset, the blowing drill, the conveying components and the liquid circuit are emptied, air is extracted, saline is extracted, blood is extracted, and the extracted air, saline and blood are repeatedly extracted and infused to obtain the contrast agent prepared for the first time.
[0135] Preparing the contrast agent for the Nth time according to the rest mode or the pressure mode means preparing the contrast agent for the Nth time according to the contrast agent preparation process corresponding to the rest mode or the contrast agent preparation process corresponding to the pressure mode.
[0136] In some embodiments, after the contrast agent is prepared, the ultrasound contrast preparation device controls the delivery component to deliver the prepared contrast agent to the target object, and after the prepared contrast agent is delivered, the next contrast agent preparation is performed. For example, after the first contrast agent preparation is performed according to the preparation process of the resting mode, the ultrasound contrast preparation device controls the delivery component to deliver the prepared contrast agent to the target object, and after the first contrast agent is delivered, the second contrast agent preparation is performed according to the preparation process of the resting mode or the pressure mode.
[0137] In some embodiments, when contrast medium is prepared according to the preparation process in the rest mode or the pressure mode, the display screen will also display images of multiple steps in the preparation process, for example, images showing the emptying of the delivery component and the fluid path, and images of extracting air, saline, and blood.
[0138] In this embodiment, after triggering the trigger control corresponding to the comprehensive mode, the first contrast agent preparation is performed according to the preparation process of the rest mode or the pressure mode to obtain the contrast agent prepared for the first time, and the foaming device is controlled according to the rest mode or the pressure mode to perform the Nth contrast agent preparation to obtain the Nth contrast agent prepared. When multiple contrast agent preparations are required, there is no need to jump to the user operation interface to click the trigger control of the foaming mode to execute the next contrast agent preparation, which saves time and simplifies the process of multiple contrast agent preparations.
[0139] In one embodiment, the automatic foaming control method further comprises:
[0140] The prepared contrast medium is delivered to a target object to be delivered, and an image of the delivery of the contrast medium to the target object is displayed.
[0141] Display and / or announce the time that has passed since the contrast agent was delivered to the target object.
[0142] According to the duration, the contrast images of the target object at multiple time points after the contrast agent is delivered are displayed.
[0143] The pressure holding value corresponding to the target object during the delivery of contrast agent is displayed, and when the infusion pressure value meets the preset pressure holding condition, the first mark representing the reliability of the contrast image is displayed.
[0144] The action of delivering the contrast agent to the target object can be automatically performed after the contrast agent is prepared, or it can be performed after triggering the delivery control displayed on the display screen of the ultrasound contrast preparation device. If the action of delivering the contrast agent to the target object is performed after triggering the delivery control displayed on the display screen of the ultrasound contrast preparation device, when the contrast agent has been prepared and the delivery control has not been triggered, the delivery component will continue to repeatedly extract and infuse air, saline and blood to prevent the bubbles in the contrast agent from disappearing and affecting the contrast effect.
[0145] The image of the delivery / injection of contrast agent into the target object is displayed on the display screen of the ultrasound contrast preparation device, such as Figure 8 The image of delivering contrast agent to the target object may be a static image of delivering contrast agent to the target object or a dynamic image of delivering contrast agent to the target object, and the dynamic image may be a real-time dynamic image of delivering contrast agent to the target object or a simulated dynamic image of delivering contrast agent to the target object.
[0146] The time after delivery of contrast agent refers to the time after delivery of contrast agent. The time can be displayed on the display screen of the ultrasound contrast preparation device, such as Fig. 9 The duration can also be announced by voice through a voice module loaded in the ultrasound contrast preparation device, or the duration can be displayed on a display screen of the ultrasound contrast preparation device and announced by voice through a voice module loaded in the ultrasound contrast preparation device.
[0147] The multiple time nodes refer to contrast images at different time points after the contrast agent is delivered to the target object, for example, a contrast image is displayed 5 seconds after the contrast agent is delivered, and a contrast image is displayed 10 seconds after the contrast agent is delivered.
[0148] Contrast images refer to medical images obtained by using contrast agents to enhance the visibility of specific tissues or organs in medical imaging. Contrast agents can help operators see the details of blood vessels, organs or other structures more clearly, improving the accuracy and reliability of diagnosis. Contrast images can be displayed on the display screen of an ultrasound contrast preparation device or on a specific medical imaging device. For example, at different time points after the delivery of contrast agents, by using a medical imaging device to scan the target object, contrast images of multiple time points can be obtained and displayed. Medical imaging equipment includes but is not limited to X-ray machines, computer tomography equipment, magnetic resonance imaging equipment, digital subtraction angiography equipment, and ultrasound imaging equipment.
[0149] By acquiring angiography images at multiple different time points, the blood flow dynamics in the target object's blood vessels can be observed, the blood flow velocity and direction can be evaluated, the blood perfusion of the target object's myocardium / tumor can be observed, and the location and degree of blood flow obstruction in the target object can be quickly evaluated.
[0150] The pressure holding value refers to the pressure value of the target object within a preset time length when the contrast agent is delivered in the pressure mode or in the comprehensive mode according to the process of the pressure mode. The 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, such as Fig.10 shown.
[0151] The preset holding pressure condition refers to the preset holding pressure value. Meeting the preset holding pressure condition means that 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 the preset difference.
[0152] The first mark is displayed on the display screen of the ultrasound contrast preparation device to remind the operator that the contrast image obtained is reliable. The first mark includes, but is not limited to, text and images. For example, the way to represent the reliability of the contrast image with text may be to display "image is reliable" on the display screen, and the way to represent the reliability of the contrast image with an image may be to display a preset image on the display screen to indicate that the contrast image is reliable.
[0153] In some embodiments, if the pressure holding value does not meet the preset pressure holding 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 includes a manual delivery control. After the operator triggers the manual delivery control, the ultrasound contrast 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.
[0155] In some embodiments, when the contrast agent is delivered, the display screen of the ultrasound contrast preparation device also includes a continue control and an end control. The continue control is used to continue to prepare and deliver the contrast agent according to the next mode, and the end control is used to jump to the user operation interface.
[0156] In this embodiment, the prepared contrast agent is delivered to the target object to be delivered, and the image of delivering the contrast agent to the target object is displayed at the same time, and the time elapsed after the contrast agent is delivered to the target object is displayed and / or broadcasted. In this way, the contrast images of multiple time nodes after the contrast agent is delivered to the target object can be obtained in time according to the time. By displaying the pressure holding value corresponding to the target object during the contrast agent delivery process, it is convenient to compare the pressure holding value with the preset pressure holding condition, so as to judge whether the obtained contrast image is reliable.
[0157] In one embodiment, displaying a user operation interface includes:
[0158] Respond to a power-on operation and perform system initialization and power-on self-test when the power is on.
[0159] After the system is initialized and the power-on self-test is correct, the user login interface is displayed.
[0160] In response to a login information entry operation triggered on a user login interface, the user's login information is obtained.
[0161] When the login information is successfully verified, 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. System initialization refers to initializing each module, component, or function of the ultrasound contrast preparation device. For example, initializing the system clock, initializing the input and output ports, initializing the voice module, initializing the storage module, initializing the QR code module, initializing the USB (Universal Serial Bus) host mode, initializing the motion control module, initializing the display screen, etc.
[0163] The power-on self-test mainly refers to the detection of each module, component, or function when the ultrasound contrast preparation device is turned on to see whether it can be used normally. For example, when the device is turned on, it detects 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 / SPIFLASH 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 micro switch are abnormal, whether the display screen is mounted, whether the bottom plate is mounted, etc.
[0164] The self-check / initialization of each module, component, or function is performed in sequence, which can ensure the stability and reliability of the ultrasound contrast preparation device, avoid resource competition caused by the simultaneous initialization / simultaneous power-on self-check of all modules, components, and functions, and affect the normal operation of the ultrasound contrast preparation device. At the same time, when problems occur in the initialization / power-on self-check, it is also easier to locate the specific module, specific component, or specific function where the problem is.
[0165] Login information refers to credentials and information used to verify identity and access the ultrasound contrast preparation device. For example, the 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, and may be biometric information collected by the information collection module of the ultrasound contrast preparation device, wherein the biometric 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 user who has been authorized to log in to the ultrasound contrast preparation device and stored in the identity authentication database. Specifically, the successful verification of the login information can be understood as the identity information that is consistent with the login information is stored in the identity authentication database. For example, when the login information refers to biometric information, the successful verification can be understood as the identity information that is the same as the entered biometric information is stored in the identity authentication database.
[0167] In some embodiments, if the ultrasound contrast preparation device is logged in through account information and password information, when the user logs in to 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 remember password information was checked during the last login, the password information of the last login will be loaded at the same time. If the remember password information was not checked during the last login, the password information needs to be entered before the login operation is triggered. After the login operation is triggered, the ultrasound contrast preparation device will check whether the account information is empty, check whether the password information is empty, check whether the account information is in the identity authentication database, and check whether the entered password information matches the account information. If the check passes, the ultrasound contrast preparation device will display the match passed on the display screen and jump to the user operation interface. If the ultrasound contrast preparation device is logged in for the first time, the account information and password information need to be entered in the user login interface, and the user operation interface will be displayed if the entered account information and password information match.
[0168] In some embodiments, the user types for logging into the ultrasound contrast preparation device include but are not limited to the first user, the second user, and the third user, wherein the first user has higher authority than the second user and the third user, and the second user has higher authority than the third user. For example, the third user is an ordinary user, and the authority he has is to operate the bubble service, view the setting parameters of the bubble service, view all users and types, and modify the password. The second user includes all the permissions of the third user, and can also add / delete the third user, view the records in the record list, set the parameters of the bubble 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 number of registrations of the first user, the second user, and the third user can also be set to be less than or equal to the preset registration number. For example, the number of registrations of the first user is less than or equal to the first preset registration number, the number of registrations of the second user is less than or equal to the second preset registration number, and the number of registrations of the third user is less than or equal to the 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, the user's login information is obtained by responding to the login information entry operation triggered on the user login interface. When the login information is successfully verified, the user operation interface is displayed, which can prevent untrusted users from logging into the ultrasound contrast preparation device and reduce the risks of the ultrasound contrast preparation device.
[0170] In one embodiment, the automatic foaming control method further comprises:
[0171] In response to the monitoring result of at least one physiological parameter of the target object and the acquisition operation of the timed self-test result, the timed self-test result is the result obtained by the ultrasound contrast preparation device performing a timed self-test according to a preset self-test cycle.
[0172] When at least two results are abnormal, the priority corresponding to each abnormal result is determined.
[0173] When the priorities corresponding to 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] Among them, physiological parameters include but are not limited to heart rate, blood pressure, respiratory rate, blood oxygen saturation, blood oxygen value, body temperature, state of consciousness, skin color and temperature, pain and discomfort, allergic reactions, renal function, electrocardiogram, hemodynamic parameters, urine volume and electrolyte levels, etc.
[0175] At least two results are abnormal, which means that at least two monitoring results of physiological parameters are abnormal, or at least two timed self-examination results are abnormal, or at least one monitoring result of physiological parameters is abnormal, and at least one timed self-examination result is abnormal.
[0176] The abnormal monitoring result of the physiological parameter means 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 to which the actual physiological parameter deviates from the standard range, or according to the length of time the actual physiological parameter deviates from the standard range.
[0177] Abnormal results of the scheduled self-test are usually caused by improper operation or when the ultrasound contrast preparation device fails. The priority of abnormal scheduled self-test results can be divided according to the severity of the fault. Specifically, hardware failures that may cause the ultrasound contrast preparation device to be completely unable to operate, such as power failures, motherboard failures, etc., have the highest priority. Failures that may affect the main functions of the ultrasound contrast preparation device but will not completely paralyze the ultrasound contrast preparation device, such as hard disk failures, memory errors, etc., have a higher priority. Failures that do not affect the main functions of the ultrasound contrast preparation device but may cause future problems, such as abnormal fan speed, excessive temperature, etc., have a lower priority. When an abnormal self-test result with a higher priority occurs, the ultrasound contrast preparation device will stop the preparation and delivery of the contrast agent, and will wait until the abnormality is eliminated before continuing to prepare, deliver, or reset the contrast agent.
[0178] The preset self-test cycle refers to the period of timed self-test preset in the ultrasound contrast preparation device. For example, the ultrasound contrast preparation device is preset to perform a self-test every 30 minutes. The items for self-test according to the preset cycle include but are not limited to detecting whether each module, component, or function can be used normally. For example, detect whether the power supply is undervoltage / overvoltage, detect whether the temperature sensor is mounted, detect whether the system temperature is normal, detect whether the photoelectric switch / micro switch is abnormal, and detect whether the battery capacity / battery temperature is abnormal. The timed self-test of each module, component, or function is performed in sequence.
[0179] Alarm prompts of different priorities are represented in different forms. For example, the light prompt for the result with the highest priority may be a flashing red light, and the sound prompt may be "beep-beep-beep--beep-----beep-beep--beep-beep". The light prompt for the result with a higher priority may be a flashing yellow light, and the sound prompt may be "beep-beep-beep". The light prompt for the result with average priority may be a solid blue light, and the sound prompt may be "beep", where the flashing frequency of the yellow light may be the same as that of the red light, or lower than that of the red light. Information prompts refer to the display of abnormal results and the priority of the abnormal results on the display screen of the ultrasound contrast preparation device.
[0180] In some embodiments, the ultrasound contrast preparation device further includes an alarm stop control, which is used to stop the alarm and resume the alarm. For example, when the ultrasound contrast preparation device outputs an alarm prompt, the alarm stop control is triggered, and the ultrasound contrast preparation device stops outputting the alarm prompt, and the ultrasound contrast preparation device starts a 120s countdown. After 120s, if the abnormality has not been resolved, the ultrasound contrast preparation device will continue to output the alarm prompt. If the abnormality has been resolved, the ultrasound contrast preparation device will not continue to output the alarm prompt.
[0181] In this embodiment, when the priorities corresponding to the results of each exception are inconsistent, an alarm prompt for the result with the highest priority is output, so that the most important exceptions can be handled first to minimize potential losses and impacts and reduce risks.
[0182] In one embodiment, the user operation interface includes a blood pressure monitoring control for performing blood pressure monitoring. The automatic foaming control method also includes:
[0183] 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 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, 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 by each measurement is displayed.
[0185] When the blood pressure value of the target object does not meet the preset blood pressure condition, a second indicator indicating that the blood pressure monitoring result of the target object is abnormal is displayed.
[0186] Among them, automatic measurement refers to automatically measuring blood pressure once at intervals of a preset measurement period, and continuous measurement refers to measuring the blood pressure of the target object uninterruptedly. 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 one execution, and does not need to be manually terminated, and will not be continued for the second time. When the preset measurement mode is automatic measurement / continuous measurement, the operator needs to manually terminate the blood pressure measurement of the target object.
[0187] The preset blood pressure conditions include preset systolic pressure limit values, diastolic pressure limit values, mean pressure limit values, and pulse rate limit values. 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 does not meet the preset blood pressure conditions when one or more of the following situations occur: the systolic pressure of the target object is outside the preset 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 prompts for systolic pressure, diastolic pressure, mean pressure, and pulse rate can also be turned on or off. For example, if you choose to turn off the alarm prompt for systolic pressure, no alarm prompt will be issued when the systolic pressure of the target object is outside the preset systolic pressure limit value.
[0188] The preset measurement cycle and the preset blood pressure condition are pre-set in the ultrasound contrast preparation device.
[0189] The second mark is displayed on the display screen of the ultrasound contrast preparation device to prompt the operator that the target object's blood pressure monitoring result is abnormal. The second mark includes, but is not limited to, text and images. For example, the way to represent the abnormal blood pressure monitoring result with text may be to display "blood pressure monitoring result is abnormal" on the display screen, and the way to represent the abnormal blood pressure monitoring result with an image may be to display a preset 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 cycle 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 process of preparing and delivering the contrast agent without manually triggering the blood pressure monitoring multiple times. Therefore, when the blood pressure value is abnormal, corresponding measures can be taken in time to avoid other symptoms of the target object.
[0191] In one embodiment, the ultrasound contrast preparation device is assembled in a movable trolley, the ultrasound contrast preparation device is detachably connected to the trolley, and the user operation interface includes an ascending control for controlling the ascending of the trolley, a descending control for controlling the descending of the trolley, and a locking control for locking the trolley. The automatic foaming control method also includes:
[0192] In response to the trigger operation for 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 that is less than or equal to the maximum allowed height.
[0193] In response to the trigger operation for 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 greater than or equal to the minimum allowed height.
[0194] When the trolley is raised to the first height, or lowered to the second height, in response to a trigger operation on the trolley locking control, the trolley is prohibited from rising or falling.
[0195] Among them, the trolley lock control can be used to fix the height of the trolley when triggered, prohibiting the trolley from rising or falling. The maximum allowable height refers to the maximum height that the trolley can reach when rising. The minimum allowable height refers to the minimum height that the trolley can reach when descending.
[0196] The first height can be determined according to the triggering time of the rising control. For example, if the rising control is pressed for 10 seconds, the trolley will rise for 10 seconds at a preset rising speed, and the height reached after rising for 10 seconds is the first height. The first height can also be determined according to the number of times the rising control is triggered. For example, if the rising control is triggered once, the trolley will rise to a preset fixed height, and if the rising control is triggered twice, the trolley will rise to two preset fixed heights. 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 lock control is not triggered and the current height of the trolley is equal to the maximum allowed height, the height of the trolley will not change after the rise control is triggered. At the same time, the display screen of the ultrasound angiography preparation device can also prompt that the trolley has reached the maximum allowed height.
[0198] In some embodiments, when the trolley lock control is not triggered and the current height of the trolley is equal to the minimum allowed height, the height of the trolley will not change after the lowering control is triggered. At the same time, the display screen of the ultrasound angiography preparation device can also prompt that the trolley has reached the minimum allowed height.
[0199] In some embodiments, when the trolley lock control is triggered, the height of the trolley will not change after the up control / down 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 lock control is not triggered and the distance between the trolley's current height and the minimum allowable height is less than or equal to the preset distance, the display screen of the ultrasound contrast preparation device may also prompt that the distance between the trolley's height and the minimum allowable height is less than or equal to the preset distance.
[0201] In this embodiment, by responding to the trigger operation for the rising 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 rise to the first height; in response to the trigger operation for 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 the second height. This ensures that the trolley is allowed to be raised and lowered only when it is unlocked, avoiding the risks caused by accidental movement. It can also prevent the trolley from running beyond the safety range, reduce the risk of damage to the trolley and the ultrasound angiography preparation device, and avoid the trolley from causing damage to the target object during movement.
[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 trigger operation on a record list control, a record list is displayed. The record list includes at least one of the following records.
[0204] Test records, including scheduled self-test results, power-on self-test results, and angiographic images in various modes.
[0205] Consumables records, including details of consumables used in each mode.
[0206] Operation records, including operation logs of ultrasound contrast preparation devices.
[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 trigger operation on a 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 conditions, preset measurement cycle, blood pressure alarm switch status, and pressure unit for each type of target object.
[0211] Foaming parameter controls: used to set blood drawing speed, device type, injection method in each foaming mode, contrast agent preparation speed, contrast agent injection speed, pressure holding time, number of repeated preparations, repeated preparation interval, restore default values, consumable model, and air content.
[0212] Blow handle parameter control: used to set the preset pressure value for the target object.
[0213] Time parameter controls: used to set the time and display the time format.
[0214] Language control: Used to set the language.
[0215] Brightness Volume Controls: Used to set the brightness and volume.
[0216] System maintenance controls: used to position the push assembly, reset the system, and establish connections with electronic devices with interconnection functions. Displays the system's software version information.
[0217] Pushing assembly: used to push the delivery assembly.
[0218] Among them, the foaming parameter control is used to set the blood drawing speed, equipment type, injection method in each foaming mode, contrast agent preparation speed, contrast agent injection speed, pressure holding time, repeated preparation times, repeated preparation interval time, restore default value, consumable model, air content, the foaming parameter setting interface corresponding to the foaming parameter control is as follows Fig.11 As shown, the blood pressure parameter setting interface corresponding to the blood pressure parameter setting control is as follows Fig.12 shown.
[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 controls 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, it controls the replacement of the blowing mask on the blowing handle. The electronic device with the interconnection function can be a device with Bluetooth function.
[0220] The push component is a component used to push the delivery component. For example, when the delivery component is loaded with prepared contrast agent, the contrast agent loaded in the delivery component can be delivered to the target object by controlling the push component to push the delivery component. The push component includes but is not limited to a motor, a pneumatic drive component, and a spring drive component. In the process of pushing the push component, the pushing method mainly includes pushing at high speed throughout the process, and pushing at low speed first and then at high speed. The time required for pushing is determined according to the speed of the push component and the amount of contrast agent. For example, when the push component pushes the delivery component at high speed throughout the process to deliver 10 ml of contrast agent to the target object, the time required is 2s.
[0221] In some embodiments, in response to a trigger operation on a time parameter control, a time parameter setting interface is displayed, time information is input in the time parameter interface, and if the time information is input correctly, the input time information is written into the system's RTC (Real-Time Clock) to complete the setting of the time parameters. The time information mainly includes year, month, day, hour, etc. If the time information is input incorrectly, the ultrasound contrast preparation device will also prompt that the time information is input incorrectly.
[0222] The present application also provides an application scenario, which applies the above-mentioned automatic foaming control method.
[0223] Specifically, the application of the automatic foaming control method in this application scenario is as follows:
[0224] When the ultrasound contrast 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 ultrasound contrast preparation device. After the ultrasound contrast preparation device is turned on, the display screen enters the power-on interface, and initializes the system clock, input and output ports, voice module, storage module, QR code module, USB host mode, motion control module, display screen, etc. of the ultrasound contrast preparation device in sequence. After the system initialization is completed, the ultrasound contrast preparation device detects whether the power supply 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 micro switch are abnormal, whether the display screen is mounted, whether the bottom plate is mounted, etc.
[0225] When the ultrasound contrast preparation device is initialized and the power-on self-check is correct, the user login interface is displayed. When the ultrasound contrast preparation device is logged in through biometric information, the information collection module of the ultrasound contrast preparation device collects the biometric information of the operator and matches the collected biometric information with the identity information in the identity authentication database. When the identity information that is the same as the entered biometric information is stored in the identity authentication database, the user operation interface is displayed on the display screen of the ultrasound contrast preparation device, such as Fig.13 As shown. Among them, the user operation interface includes a record list control, a parameter setting control, a consumable replacement control, a rest mode trigger control, a pressure mode trigger control, a comprehensive mode trigger control, a blood pressure monitoring control, an up control, a down control, and a lock control. When the ultrasound contrast preparation device needs to log in through account information and password information, 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 remember password information was checked during the last login, the password information of the last login will be loaded at the same time. If the remember password information was not checked during the last login, the password information needs to be entered before the login operation is triggered.
