[0023] Figure 4 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Detailed Implementation

[0024] To help those skilled in the art better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the description of the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, software, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but also includes steps or units not listed, or other steps or units inherent to such processes, methods, products, or apparatus.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] like Figure 1 As shown, Figure 1 This is a schematic diagram of a ventricular assist system (VAS). The VAS includes a ventricular assist device, a flushing device, and a system monitor. The flushing device and the VAS are communicatively connected to the system monitor. The VAS is implanted in the patient's body, crossing the aortic valve, with the proximal end of the device located within the aorta and the distal end within the left ventricle. The VAS includes a motor and an impeller. The system monitor powers the VAS, driving the motor to rotate, which in turn drives the impeller, pumping blood from the left ventricle into the aorta to provide partial or complete assistance to the circulatory system. The system monitor and the flushing device are located outside the patient's body. The system monitor controls and displays data on the VAS and flushing device, and provides functions such as fault detection alarms and data logging. The flushing fluid device maintains a pressure barrier between the blood and the motor. By connecting the flushing tubing of the flushing device to the motor bearing in the VAS, the fluid pressure created by the flushing fluid flowing in the opposite direction to the blood flow isolates the blood from the motor, preventing blood from entering the motor.

[0028] Furthermore, the system monitor includes a display screen and a controller. The display screen is used to show the current operating status information of the ventricular assist device. The display screen is touch-sensitive, allowing users to interact with the device by clicking or pressing it. The display screen is communicatively connected to the controller, which receives touch commands from the user on the display screen to set the operating parameters of the ventricular assist device and control the display screen's output.

[0029] The controller monitors system operations via various software applications, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the system software structure of the controller provided in this application embodiment. The system software of the controller includes: system software, power control software, pump control software, and flushing control software. The power control software is used to monitor the power status of each module, and also serves as a communication bridge between the system software and the pump control software and flushing control software to realize data forwarding; the pump control software is used to realize the operation control of the ventricular assist device; the flushing control software is used to realize the operation control of the flushing device; and the system software realizes the monitoring and control of the system monitor.

[0030] The system monitor is equipped with a power button. When the user presses the power button, the system software, power control software, pump control software, and flushing control software are also launched simultaneously. After the system software starts, it controls the display screen and opens the UART serial port to communicate with the power control board, sending and receiving data from the power control board, pump controller, flushing system, fiber optic pressure sensor, etc., and displays the received operating data on the corresponding page for medical staff or patients to view.

[0031] If the system software crashes due to various uncertain and complex factors during the operation of the system monitor, causing problems such as screen crashes, black screens, and lag, patients or medical staff can only solve the problem by restarting the system monitor. However, restarting the system monitor takes time and requires patients or medical staff to manually follow the steps, which is cumbersome and affects the user experience.

[0032] To address this issue, this application proposes a page recovery method. The system software monitors the running status of the application interface program running on the system monitor in real time. When the system software detects that the running status of the application interface program running on the system monitor is abnormal, causing abnormal display on the screen, it restarts and displays the page at the time of the abnormal display, the default page, or another page after restarting. This can automatically resolve various uncertain and complex factors that cause problems such as screen crashes, black screens, and lag, thereby improving the user experience.

[0033] Based on the above description, this application will now be described from the perspective of method examples.

[0034] Please see Figure 3 , Figure 3 This is a schematic flowchart of a page restoration method provided in an embodiment of this application, applied to, for example... Figures 1-2 The ventricular assist system shown. (Example) Figure 3 As shown, the method includes the following steps.

[0035] S310 The controller monitors the target's operating status, which is displayed on the screen.

[0036] In this application, a flag bit can be set in the system software to indicate the operating status of the display screen. The operating status of the display screen can include: normal, crash, freeze, and black screen. During operation, the display screen can feed back its operating status to the system software in real time. The system software can detect the operating status of the display screen in real time by reading this flag bit, and then perform corresponding operations based on its current operating status when the display screen displays abnormalities. Specifically, the display screen maintains the value of this flag bit during operation, and sets the value of this flag bit to represent its different operating states, such as 00 for normal, 01 for crash, 10 for freeze, and 11 for black screen. Of course, other methods of indicating the operating status of the display screen can also be used in this application; this application is not limited to the specific implementation method of indicating the operating status of the display screen.

[0037] S320. When the controller determines that the display screen is abnormal based on the target operating status, it obtains page information. The page information includes n pages, which are arranged in ascending order according to the time sequence of the display screen, where n is a positive integer greater than 1.

[0038] The system software records the pages displayed on the screen in real time after the controller is turned on, and stores them in chronological order of display time. When the system software determines that the screen display is abnormal based on the target's operating status, it can retrieve all stored pages, and then restart the system software based on the page information to redisplay the displayed pages.

[0039] In this application, the page displayed on the screen has one or more buttons. After human-computer interaction, the system software can jump to the corresponding page through the button touched by the user. Therefore, there are relationships between the pages displayed on the screen, especially between adjacent pages. For example, the page information also includes the relationship between each page and other pages among the n pages. This relationship is used to indicate the shortest jump path between pages, that is, the minimum number of pages required to jump from one page to another.

[0040] S330. The controller controls the display screen to display a first page based on the page information. The first page is included among n pages. Controlling the display screen to display the first page based on the page information includes: acquiring exception information causing the display screen to display abnormally, and determining the exception function based on the exception information; comparing each of the n function sets with the exception function to obtain m target function sets, where each target function set does not include the exception function, and each function set is one or more functions called to display a page, where m is a positive integer less than or equal to n; determining the first page from the n pages based on the m target function sets; and controlling the display screen to display the first page.

[0041] When the display malfunctions and prevents the user from obtaining operational information about the ventricular assist device and / or flushing device, the system software can automatically restart and control the display to show the first page. This allows the user to display the page normally without restarting the system monitor, resolving issues such as screen crashes, black screens, and lag caused by various uncertain and complex factors.

[0042] For example, the first page could be the page displayed when the screen malfunctions, the page preceding the malfunctioning page, or the default page. When the screen malfunction occurs randomly, the page will display correctly when the system software regains control of the screen to display the page from the point of malfunction. When the screen malfunction is caused by a program error in the system software, i.e., an error in the function code or an execution error, there may be issues when the screen displays the page from the point of malfunction again. Therefore, the system software can control the screen to display the page preceding the malfunctioning page or the default page.

[0043] The exception information includes at least one of the following: the address of the illegal operation, the register value, and the CPU state.

[0044] When the system software controls the display screen to show a page, it needs to call one or more functions, such as functions to read the operating parameters of the ventricular assist device, functions to display the read ventricular assist operating parameters in graphical form, functions to read alarm information, functions to read the current charging status, and so on. When the display screen shows an abnormality, the system software can obtain the system operation log, search for the memory information of the system software at the time of the abnormality in the operation log, extract the program address where the abnormality occurred, the address of the illegal operation, the values ​​of various registers in the processor, and the processor status, etc., and trace back to the function call sequence in which the abnormality occurred, as well as the name of the called function and the file to which it belongs, thereby determining the abnormal function that caused the display screen to malfunction.

[0045] For example, the system software can obtain the functions called when displaying each of the n pages, as well as the functions called when navigating from one page to another. These functions for each page are then grouped into n function sets. Each of these n function sets is then compared with an exception function to filter out those sets that do not contain exception functions. If a function set contains an exception function, it indicates that the page corresponding to that function set may cause system software malfunctions during display. Subsequently, m pages corresponding to the m target function sets are selected from the n pages, and the first page is chosen from these m pages to control the display, thus completely avoiding display errors caused by the exception function.

[0046] For example, the system software can obtain a first function set and multiple second function sets for each of the n pages. The first function set includes one or more functions to be called to display the page, and the second function set includes one or more functions to be called to navigate from the page to another page. The first function set and the multiple second function sets are compared with exception functions to determine whether the exception function is included in either the first function set or the multiple second function sets. If the exception function is included in the first function set, the page corresponding to the first function set is deleted from the n pages; if the exception function is not included in the first function set, but is included in the multiple second function sets, the page corresponding to the second function set containing the exception function is deleted from the n pages. Then, the first page is determined from the filtered pages.

[0047] Optionally, determining the first page from the n pages based on the m target function sets includes: filtering out m pages corresponding to the m target function sets from the n pages; determining the correlation degree between each of the m pages and the abnormal page based on the correlation relationship, wherein the abnormal page is the page where the display screen displays an abnormality; and determining the first page from the m pages based on the correlation degree and the importance of each page.

[0048] In this application, the display screen is primarily used to show the operating status of the ventricular assist device and / or flushing device. The pages that can be displayed by the system software control may include a ventricular assist device performance parameter display page, a flushing device performance parameter display interface, setting pages for multiple different ventricular assist device parameters, setting pages for multiple different flushing device parameters, alarm information pages, patient information pages, system information pages, software upgrade pages, etc. The importance of these pages varies depending on the application scenario. For example, during software upgrades, the software upgrade page and system information page are of higher importance; during setting flushing device parameters, the flushing device performance parameter display interface is of higher importance; during routine monitoring of the ventricular assist device and flushing device operating status, the ventricular assist device performance parameter display page and the flushing device performance parameter display interface are of higher importance.

[0049] After selecting m pages from n pages, the system software can determine the current application scenario of the display based on the function of the pages displayed within a preset time period before the display malfunctions. Then, based on this application scenario, it determines the importance of each of the m pages. The correlation between pages can be measured by the shortest jump path; the shorter the shortest jump path, the greater the correlation between pages. This application determines the page the user currently expects to display by measuring the correlation between each of the m pages and the malfunctioning page when the display malfunctions, as well as the importance of each page in the current application scenario. Therefore, it selects the first page the user currently expects to display from the m pages for display.

[0050] For example, if the display screen was previously showing the performance parameters of the ventricular assist device (VAP), and the application scenario was monitoring the VAP's operating status, and when the user clicks a setting button for a parameter on the VAP's performance parameters display page, the redirection to the VAP parameter settings page is delayed. In this case, the shortest path between the VAP's performance parameters display page and the VAP parameter settings page is 1, so the system software can prioritize displaying the VAP's performance parameters display page as the first page.

[0051] After determining the first page, the system software automatically starts and directly controls the display screen to show the first page. During the system software's automatic startup process, the power control software, pump control software, and flushing control software continue to run, thereby avoiding data loss during the time it takes to start the system monitor; and the display screen directly shows the first page after the system software starts, which reduces the time spent jumping from the restart page to the first page and improves human-computer interaction, thus enhancing the user experience.

[0052] In one example, the controller controls the display screen to display a first page based on the page information, including: the system software dividing the n pages into p main pages and q sub-pages according to the function of each page, where each sub-page is a page that is navigated to after human-computer interaction on the main page, and p and q are both less than or equal to m; the system software acquiring exception information that causes the display screen to display abnormally, and determining an exception function based on the exception information; comparing the function set of each main page and the function set of each sub-page with the exception function; if the first function set includes the exception function, then the main page of the sub-page corresponding to the first function set is determined as the first page, and the first function set is the function set of any of the sub-pages; if the second function set includes the exception function, then the main page with the shortest navigation path to the main page corresponding to the second function set is determined as the first page, and the second function set is the function set of any of the main pages; the system software starts automatically, and controls the display screen to display the first page after startup.

[0053] In this system, a page can be either a main page or a subpage. For example, the main page of the system information page is the ventricular assist device performance parameter display page, and the system information page is also the main page of the software upgrade page. The system software divides pages into subpages and / or main pages based on their function and the relationships between them. Then, it compares the identified exception function with the function sets of each subpage and each main page. If the exception function is included in the function set of one of the subpages, its main page is displayed as the first page. If the exception function is not included in the function set of one subpage, but is included in the function set of one of the main pages, the main page with the shortest jump path to that main page is displayed as the first page. This approach resolves display anomalies while also displaying the page the user expects as much as possible.

[0054] Optionally, the method further includes: if the first page displays abnormally within a preset time, the system software controls the display screen to display a second page, the second page including the performance parameters of the ventricular assist device and / or the flushing device.

[0055] If the display screen still shows an abnormality after the system software automatically starts and displays the first page, the system software will directly display a second page after automatic startup, which includes the performance parameters of the ventricular assist device and / or flushing device, so that the user can check the operating status of the ventricular assist device and / or flushing device in a timely manner after the display screen shows an abnormality.

[0056] Optionally, the method further includes: the controller obtaining the version number and compilation time of the system software; the controller storing the exception information, the version number and the compilation time, or sending the exception information, the version number and the compilation time to a client bound to the system monitor.

[0057] In this application, since display abnormalities may occur randomly and testers may find it difficult to reproduce and analyze the cause of the problem, the system software obtains the current system software version number and compilation time after detecting a display abnormality, and stores the system software version number, compilation time and abnormal information of this display abnormality together as an abnormality report. The abnormality report is then sent to the client bound to the system monitor so that testers can analyze the cause of the problem in a timely manner.

[0058] As can be seen, this application proposes a page recovery method. A controller monitors the target operating state, which is the operating state of the display screen. When the controller determines that the display screen is abnormal based on the target operating state, it obtains page information, which includes n pages arranged in ascending order according to the time sequence of the pages displayed on the display screen. The controller then controls the display screen to display the first page based on the page information, and the first page is included among the n pages. This application's controller monitors the display's operating state in real time. When it detects a system software malfunction causing a display screen abnormality, the controller automatically controls the display screen to display the first page. This avoids the problem of the display screen crashing, going black, or freezing due to various uncertain and complex factors, requiring patients or medical staff to restart the system monitor, thus improving the user experience.
