Description

Technical Field

[0001] This invention relates to the field of detection terminal technology, and in particular to a non-invasive intra-abdominal pressure monitoring device for newborns. Background Technology

[0002] Intra-abdominal pressure monitoring is a crucial diagnostic and treatment method in neonatal intensive care. Abnormally high intra-abdominal pressure can lead to abdominal compartment syndrome, seriously threatening the lives of newborns. Currently, commonly used intra-abdominal pressure monitoring methods are mainly divided into two categories: invasive and non-invasive. Invasive methods, with bladder catheter manometry as the gold standard, require an invasive procedure to insert the catheter into the newborn's bladder. This not only causes pain to the delicate newborn but also carries risks such as urinary tract infection and organ damage. Furthermore, the procedure is complex and not suitable for continuous bedside monitoring. Non-invasive methods mainly include ultrasound and abdominal bandage-based monitoring. While these methods avoid the risks of invasive procedures, existing non-invasive monitoring equipment has significant shortcomings.

[0003] The graphical user interface (GUI) designs of existing non-invasive testing devices are mostly general-purpose and not specifically adapted for neonatal monitoring scenarios. On the one hand, test data is displayed in a scattered manner, requiring medical staff to switch between multiple interfaces to view key parameters such as intra-abdominal pressure, temperature, and abdominal contents, making it difficult to quickly capture abnormal information and meet the clinical needs of rapidly changing neonatal conditions requiring urgent responses. On the other hand, the GUI only serves the function of data presentation and lacks effective interaction with the testing module and mobile interface. The verification, classification, and storage of test data must be completed manually, which is inefficient and prone to errors. At the same time, existing dual-terminal GUIs mostly involve one-way data transmission, and mobile operations cannot be synchronized to the testing instrument in real time, resulting in poor consistency of cross-terminal operations and affecting the continuity of monitoring. The data presentation format is also limited, displaying only isolated values, requiring medical staff to manually correlate multiple parameters for judgment, increasing the difficulty of data interpretation and the risk of misjudgment. Summary of the Invention

[0004] In this section, as well as in the abstract and title of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this section, the abstract, and the title of this application, and such simplifications or omissions shall not be used to limit the scope of the invention.

[0022] In order to make the purpose, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention with reference to the drawings of the specification.

[0023] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figure 1 This embodiment is the first embodiment of the invention. The non-invasive intra-abdominal pressure monitoring device for newborns in this embodiment includes a data acquisition unit 100, a display unit 200, and a control unit 300. The data acquisition unit 100, the display unit 200, and the control unit 300 are connected by wired or wireless communication.

[0027] The acquisition unit 100 is a non-invasive acquisition module, including detection elements such as pressure sensors and tension sensors. The pressure sensor is attached to a designated area on the newborn's abdomen to collect detection data related to intra-abdominal pressure. The tension sensor is attached synchronously with the pressure sensor to collect verification data related to abdominal wall tension. The detection elements of the acquisition unit 100 are made of flexible materials to avoid pressure or damage to the newborn's delicate skin. The acquisition frequency can be adjusted according to subsequent operation instructions. The default acquisition frequency is 1 time / minute. The acquired data is transmitted to the control unit 300 for processing in real time.

[0028] The display unit 200 includes a first graphical interface 201 and a second graphical interface 202. The first graphical interface 201 is the main display interface of the detector, located on the front of the detector terminal. It uses a high-definition touch screen with a size of 7 inches and a resolution of 1920×1080. It is used to display the detection data transmitted by the acquisition unit 100 in real time, including the specific value and trend of intra-abdominal pressure. The interface layout is clear, and the data display area occupies no less than 70%, which is convenient for medical staff to view quickly. The second graphical interface 202 is an auxiliary interactive interface, which can be set on the touch screen on the side of the detector terminal. It uses a 5-inch high-definition touch screen with a resolution of 1280×720. It is used to receive operation commands from medical staff, execute preset functions, and realize visual interaction.

[0029] The control unit 300 is the core processing module, which adopts a high-performance microprocessor model STM32H743VI. It has a built-in data processing chip, storage module, communication module and early warning module. The storage module of the control unit 300 pre-stores safety thresholds. These safety thresholds are default thresholds set based on the physiological characteristics of newborns and clinical diagnosis and treatment standards, and are used to determine whether the test data is abnormal.

[0030] After the acquisition unit 100 transmits the detection data to the control unit 300, the control unit 300 compares the detection data with the built-in safety threshold in real time. If the detection data triggers the safety threshold, i.e., the detection data exceeds the safety threshold range or the rate of change exceeds the preset threshold, the control unit 300 sends a status change command to the first graphical interface 201. The first graphical interface 201 generates a corresponding status change according to the command, such as color change, numerical flashing, etc. At the same time, the control unit 300 sends a signal to the second graphical interface 202, triggering the second graphical interface 202 to execute preset functions such as creating a directory, storing data, and visual interaction such as vibration feedback, icon flashing, etc.

[0031] The control unit 300 has a built-in status recognition module, which can automatically create a corresponding category directory in the storage directory of the second graphical interface 202 according to the status change type of the first graphical interface 201, such as single data anomaly, compound data anomaly, data collaborative anomaly, etc., and store the associated detection data and verification data in the corresponding directory according to the timestamp order. The storage format is Excel format, which is convenient for subsequent export and analysis.

[0032] When medical staff input operation commands such as adjusting safety thresholds, exporting data, and modifying monitoring frequency on the second graphical interface 202, the second graphical interface 202 transmits the operation commands to the control unit 300. After parsing the operation commands, the control unit 300 synchronizes the operation changes to the first graphical interface 201 and triggers the first graphical interface 201 to perform corresponding functional adjustments, such as updating early warning rules, adjusting data refresh cycles, and updating displays, such as hiding some charts and displaying progress prompts, to ensure the consistency and synchronization of the dual-interface operation.

[0033] The visual interaction parameters of the second graphical interface 202, such as flashing frequency and vibration frequency, are positively correlated with the parameters of the detection data or operation instructions. For example, the greater the extent to which the detection data exceeds the safety threshold, the higher the flashing frequency and the greater the vibration intensity of the second graphical interface 202. The closer the execution progress of the operation instructions is to completion, the more obvious the visual feedback, making it easier for medical staff to grasp the operation status in real time.

[0034] Example 2

[0035] Reference Figures 1-5 This is the second embodiment of the invention, and this embodiment is based on embodiment 1.

[0036] Specifically, in addition to intra-abdominal pressure, the detection data also includes abdominal temperature, gas depth, and fluid depth. The acquisition unit 100 is equipped with a temperature sensor and an ultrasound detection module. The temperature sensor is integrated next to the pressure sensor and is used to collect the abdominal temperature data of the newborn. The measurement range is 35.0~39.0℃, and the measurement accuracy is ±0.1℃. The ultrasound detection module uses a low-frequency ultrasound sensor with a frequency of 3~5MHz to detect the gas depth and fluid depth in the abdominal cavity. The measurement range is 0~20mm, and the measurement accuracy is ±0.5mm. The abdominal temperature, gas depth, fluid depth, intra-abdominal pressure, and abdominal wall tension data are collected and transmitted synchronously to the control unit 300.

[0037] Preferably, the conditions for triggering the safety thresholds include two categories. The first category is when the detected data exceeds the safety threshold, and the specific values ​​are as follows: the intra-abdominal pressure safety threshold is 0~25mmHg. This safety threshold is set based on the physiological volume of the newborn's abdominal cavity and clinical safety standards. A value below 0mmHg or above 25mmHg is considered abnormal. The intra-abdominal temperature safety threshold is 36.0~37.5℃, which is within the normal body temperature range for newborns. A value exceeding this range indicates an abnormal body temperature. The gas depth safety threshold is 5~10mm, and the fluid depth safety threshold is 5~10mm. This safety threshold is set according to the normal gas and fluid content range in the newborn's abdominal cavity. A value exceeding this range indicates an abnormality in the abdominal contents. The second category involves data change rates exceeding preset thresholds, specifically as follows: The preset threshold for intra-abdominal pressure change rate is ≥5 mmHg / h, meaning that an increase or decrease of 5 mmHg in intra-abdominal pressure per unit time is considered an abnormal rate of change; the preset threshold for abdominal temperature change rate is ≥0.5℃ / h, meaning an increase or decrease of 0.5℃ per unit time is considered an abnormal temperature change; the preset thresholds for gas depth change rate and liquid depth change rate are ≥3 mm / h and ≥3 mm / h, respectively, meaning an increase or decrease of 3 mm in gas or liquid depth per unit time is considered an abnormal change in abdominal contents. When the control unit 300 processes the detection data in real time, it simultaneously compares the data values ​​with the change rates; if either condition is met, a safety threshold warning is triggered. It not only monitors the core indicator of intra-abdominal pressure, but also simultaneously monitors abdominal temperature, gas depth, fluid depth, and abdominal wall tension verification data, achieving multi-dimensional and comprehensive physiological state monitoring; it clarifies the specific values ​​of safety thresholds and preset thresholds for rate of change, making the abnormal judgment criteria more accurate, avoiding false alarms caused by ambiguous thresholds, and improving the reliability of monitoring.

[0038] Preferably, the state changes of the first graphical interface 201 and the changes of the second graphical interface 202 are specifically divided into the following two scenarios: Scenario 1: When the intra-abdominal pressure data collected by the acquisition unit 100 is transmitted to the control unit 300, and the control unit 300 finds that the intra-abdominal pressure value is >25mmHg, it immediately sends an intra-abdominal pressure abnormality warning command to the first graphical interface 201. After receiving the command, the intra-abdominal pressure display area of ​​the first graphical interface 201 is immediately filled with red highlight, and the RGB value of the filling color is 255, 0, 0. At the same time, the intra-abdominal pressure value flashes at a frequency of 1 time per second. When flashing, the value color switches between red RGB255, 0, 0 and white RGB255, 255, 255. The flashing continues until the abnormality is resolved or medical staff confirm and handle it. Simultaneously, the control unit 300 sends a directory creation and data storage command to the second graphical interface 202. Upon receiving the command, the second graphical interface 202 automatically creates a category directory named "Abnormal Intra-abdominal Pressure," which contains three subdirectories: real-time data, historical data, and verification data. The control unit 300 stores the currently collected real-time intra-abdominal pressure data, the intra-abdominal pressure data collected in the previous 30 minutes (sorted by timestamp, one record per minute, totaling 30 historical data records), and the verification data of the synchronously collected abdominal wall tension data into the corresponding subdirectories. Once the data is stored in the directory, the second graphical interface 202 generates vibration feedback. The vibration frequency is positively correlated with the extent to which the intra-abdominal pressure exceeds the safe threshold. Specifically, when the intra-abdominal pressure is between 25 and 30 mmHg, the vibration frequency is 1 time per second; when the intra-abdominal pressure is between 30 and 35 mmHg, the vibration frequency is 2 times per second; and when the intra-abdominal pressure is greater than 35 mmHg, the vibration frequency is 3 times per second. The vibration lasts for 10 seconds. If no response is received from medical staff within 10 seconds, the vibration will repeat until the medical staff clicks the confirmation button on the interface.

[0039] Preferably, in scenario two: after the gas depth data collected by the acquisition unit 100 is transmitted to the control unit 300, the control unit 300 calculates the gas depth change rate, using 1 hour as the time unit. It calculates the change rate by the difference between the current gas depth and the gas depth 1 hour ago. If the change rate is ≥3mm / h, the control unit 300 sends a gas depth change command to the first graphical interface 201. After receiving the command, the cloud icon corresponding to the gas depth, with a size of 30×30 pixels and a light blue RGB173,216,230 color, flashes once every 0.5 seconds, and the color switches between light blue and dark blue RGB0,0,139 when flashing. Simultaneously, the control unit 300 sends a trend chart update command to the second graphical interface 202. Upon receiving the command, the second graphical interface 202 adjusts the update speed of the gas depth trend chart. The update speed is positively correlated with the rate of change of gas depth, specifically: when the rate of change of gas depth is between 3 and 5 mm / h, the trend chart update speed is once every 30 seconds; when the rate of change is between 5 and 8 mm / h, the update speed is once every 15 seconds; and when the rate of change is greater than 8 mm / h, the update speed is once every 5 seconds. This ensures that medical staff can monitor the rapid changes in gas depth in real time. By clearly defining the specific change patterns of the first graphical interface 201 and the second graphical interface 202 under different data anomaly scenarios, the anomaly warning becomes more intuitive and accurate. Medical staff can quickly identify the type and severity of anomalies through both visual and tactile feedback. Simultaneously, it enables automatic classification and storage of abnormal data without manual intervention, improving data management efficiency and providing complete data support for subsequent diagnostic and treatment analysis.

[0040] Preferably, the status change types of the first graphical interface 201 include single data anomalies. A single data anomaly refers to a situation where only one data item in the detection data collected by the acquisition unit 100 exceeds a safety threshold or its rate of change exceeds a preset threshold, while other detection data are within the normal range. For example, only intra-abdominal pressure > 25 mmHg, only intra-abdominal temperature < 36.0℃, and only gas depth change rate ≥ 3 mm / h are all considered single data anomalies. When the control unit 300 identifies that the status change type of the first graphical interface 201 is a single data anomaly, it immediately sends a directory creation command to the second graphical interface 202. After receiving the command, the second graphical interface 202 automatically creates a directory named after the single data anomaly. The directory name corresponds completely to the type of anomaly. For example, when only intra-abdominal pressure is abnormal, the directory name is "Intra-abdominal Pressure Single Anomaly"; when only intra-abdominal temperature is abnormal, the directory name is "Intra-abdominal Temperature Single Anomaly"; when only the gas depth change rate is abnormal, the directory name is "Gas Depth Single Anomaly"; and when only the liquid depth change rate is abnormal, the directory name is "Liquid Depth Single Anomaly". This directory stores only data related to a single data anomaly, including real-time collected values ​​of the anomaly data (one record per minute, continuously stored until 30 minutes after the anomaly is resolved), historical trend data (complete change curve data from one hour before the anomaly occurred to after its resolution and corresponding validation data), and abdominal wall tension data collected synchronously with the anomaly data (one record per minute, corresponding one-to-one with the test data). Other normal test data is not stored to avoid irrelevant data consuming storage resources. This dedicated directory design for single data anomaly scenarios enables precise and focused storage of anomaly data, reduces interference from irrelevant data, and facilitates medical staff in quickly locating anomaly data and tracing its trends. Simultaneously, it saves storage resources, improves data storage and retrieval efficiency, and ensures the integrity and relevance of the anomaly data.

[0041] Preferably, the status change type of the first graphical interface 201 includes composite data anomalies. Composite data anomalies refer to situations where two or more data points in the detection data collected by the acquisition unit 100 simultaneously exceed the safety threshold or the rate of change exceeds the preset threshold. Examples include intra-abdominal pressure > 25 mmHg and abdominal temperature > 37.5℃, intra-abdominal pressure change rate ≥ 5 mmHg / h and gas depth > 10 mm, and abdominal temperature < 36.0℃ and fluid depth change rate ≥ 3 mm / h. When the control unit 300 identifies the status change type of the first graphical interface 201 as a composite data anomaly, it sends a composite data anomaly directory creation command to the second graphical interface 202. After receiving the command, the second graphical interface 202 automatically creates a main directory named "Composite Data Anomalies." Subdirectories are created under the main directory according to the timestamp of the anomaly occurrence, in the format of year-month-day-hour-minute-second. Each subdirectory corresponds to one composite data anomaly event. The subdirectory stores complete four-dimensional detection data and corresponding verification data. The four-dimensional detection data includes real-time acquisition values ​​of intra-abdominal pressure, abdominal temperature, gas depth, and fluid depth: one data point every 30 seconds to ensure high-density acquisition; change rate data: calculated and recorded every hour to show the magnitude and trend of change; and abnormal duration data: the complete time period from the start of data abnormality to recovery to normal. The corresponding verification data is synchronously acquired abdominal wall tension data, one data point every 30 seconds, which is completely consistent with the timestamp of the detection data.

[0042] Simultaneously, the communication module of the control unit 300 establishes a wireless connection with the hospital's diagnostic database, automatically retrieving anonymized case data of similar composite data anomalies within the past three months. After anonymization, only key information such as test data, anomaly type, and treatment results are retained, excluding patient identity information. After the retrieval, the data of similar cases is correlated with the current test data, and displayed in a pop-up window in the second graphical interface 202 in the form of comparison charts. The comparison charts include line graphs showing the trend comparison of each abnormal data and bar graphs showing the numerical amplitude comparison of the abnormal data. The default pop-up display duration is 30 seconds, and medical staff can click the fixed button in the upper right corner of the pop-up window to extend the display time, facilitating their judgment by referring to the diagnostic experience of similar cases. A dedicated storage directory is established for composite data anomaly scenarios to achieve complete storage of multi-dimensional abnormal data, providing comprehensive data support for disease analysis; by correlating anonymized data of similar cases and displaying it in the form of comparison charts, it provides diagnostic references for medical staff, reducing the difficulty of diagnostic decisions, improving the scientificity and accuracy of diagnosis and treatment, and protecting patient privacy.

[0043] Furthermore, the status change types of the first graphical interface 201 include data-coordinated anomalies. Data-coordinated anomalies refer to situations where the rate of change of gas depth and / or liquid depth data collected by the acquisition unit 100 exceeds a preset threshold and changes in synergy with intra-abdominal pressure data. For example, intra-abdominal pressure rises synchronously when the rate of change of gas depth is ≥3 mm / h, and intra-abdominal pressure falls synchronously when the rate of change of liquid depth is ≥3 mm / h. These are all considered data-coordinated anomalies.

[0044] When the control unit 300 identifies that the state change type of the first graphical interface 201 is data coordination anomaly, it sends a command to the second graphical interface 202 to establish a directory of abdominal contents anomalies. After receiving the command, the second graphical interface 202 automatically creates a directory named abdominal contents anomaly. The directory is divided into three subdirectories according to gas anomalies, liquid anomalies, and gas-liquid mixture anomalies. The control unit 300 stores the data in the corresponding subdirectory according to the actual anomaly type.

[0045] The specific data stored in the subdirectory includes: real-time data of gas or liquid depth, one record every 20 seconds, to ensure the capture of rapid changes; change curve data with time as the horizontal axis and depth value as the vertical axis to generate a continuous change curve, with the horizontal axis unit being minutes and the vertical axis unit being mm; and synchronous intra-abdominal pressure data with the same timestamp as the gas / liquid depth data, one record every 20 seconds, recording the synchronous changes in intra-abdominal pressure.

[0046] Meanwhile, the second graphical interface 202 uses a layered progress bar to overlay the gas depth and liquid depth. The total length of the progress bar is 200 pixels, corresponding to a depth measurement range of 0~20mm. That is, the length of the progress bar is directly proportional to the depth value, with a scaling factor of 10 pixels / mm. For example, when the gas depth is 5mm, the progress bar length is 50 pixels; when the liquid depth is 8mm, the progress bar length is 80 pixels. In the layered progress bar, the gas depth progress bar is located on the upper layer and is light blue (RGB: 173, 216, 230), while the liquid depth progress bar is located on the lower layer and is light blue (RGB: 255, 192, 203). After the two progress bars are overlaid, the numerical relationship and changing trend of the gas depth and liquid depth can be intuitively displayed. Medical staff can quickly judge the abnormality of the abdominal contents by observing the changes in the length of the progress bars. By establishing a dedicated catalog of abnormal abdominal contents, targeted storage of data on the coordinated changes in gas depth, fluid depth, and intra-abdominal pressure can be achieved, facilitating the tracing of the root cause of the abnormality. The layered progress bar overlay display simplifies the comparison process of multiple data, making the data relationships more intuitive, reducing the observation difficulty for medical staff, and improving the efficiency of judging the abnormality of abdominal contents.

[0047] Furthermore, the second graphical interface 202 includes operation instructions for adjusting safety thresholds. Medical staff can initiate safety threshold adjustments on the second graphical interface 202 based on individual differences in newborns, such as weight, gestational age, underlying diseases, or clinical needs. The specific operation process is as follows: Medical staff click the threshold setting icon (40×40 pixels, gear shape, dark gray RGB: 105, 105, 105) in the main menu of the second graphical interface 202 to enter the safety threshold setting interface; In the safety threshold setting interface, select the intra-abdominal pressure threshold adjustment option. The interface displays the current default threshold of 0~25 mmHg, and a numerical input box pops up. Medical staff can input a new intra-abdominal pressure safety threshold range via the touch keyboard. The threshold is limited to 0-30 mmHg, with the lower limit not lower than 0 mmHg and the upper limit not higher than 30 mmHg, to avoid setting unreasonable thresholds. After the medical staff completes the input, they click the confirmation button at the bottom of the interface. The button is 60×30 pixels in size and green (RGB: 0,128,0), and displays the word "Confirm" in white. At this time, the safety threshold setting interface of the second graphical interface 202 displays a green checkmark icon, 30×30 pixels in size and RGB: 0,128,0. This icon disappears automatically after 2 seconds, indicating that the safety threshold modification is complete. The second graphical interface 202 transmits the modified safety threshold data to the control unit 300. After receiving the data, the control unit 300 immediately updates the built-in safety threshold parameters and simultaneously sends them to the first graphical interface 201.

[0048] Upon receiving the modified safety threshold, the first graphical interface 201 immediately updates the safety threshold warning rules. Using the modified safety threshold as the critical point, it resets the color coding rules for the intra-abdominal pressure display area: when the intra-abdominal pressure value is within the modified safety threshold range, the display area is green (RGB: 0,128,0); when it exceeds the modified safety threshold range, the display area is red (RGB: 255,0,0). The color coding is updated in real time to ensure consistency with the new safety threshold. For example, after medical staff adjust the intra-abdominal pressure safety threshold to 0~28 mmHg, when the intra-abdominal pressure is 26 mmHg, the intra-abdominal pressure display area of ​​the first graphical interface 201 displays green; when the intra-abdominal pressure is 29 mmHg, the display area displays red and triggers a warning. It supports personalized adjustment of safety thresholds to adapt to individual differences among newborns and clinical treatment needs, thus improving the versatility of the device. The dual-interface threshold synchronization update mechanism ensures operational consistency and avoids false alarms caused by asynchronous thresholds. At the same time, the real-time adjustment of color labeling rules allows medical staff to intuitively understand whether the data is within the safe range, improving the ease of operation and monitoring accuracy.

[0049] Furthermore, the operation commands of the second graphical interface 202 include data export. Medical staff can trigger the data export operation on the second graphical interface 202 when needed, such as in scenarios like medical record archiving, diagnosis and treatment analysis, and referral handover. The specific operation process and dual-interface response are as follows: Medical staff click the data export button in the data management menu of the second graphical interface 202. The button is 50×25 pixels in size, blue (RGB: 0,0,255), and displays the word "Export" in white, triggering the data export command. After receiving the export command, the operation of the second graphical interface 202 changes. In the exporting state: the original data export button is replaced by a rotating loading icon. The icon is circular, 20 pixels in diameter, and consists of three sectors. The color is blue (RGB: 0,0,255). The rotation speed is 1 revolution / second. The export progress percentage is displayed to the right of the loading icon in integer form, accurate to 1%. The progress percentage starts from 0% and increases in real time until it reaches 100%. The second graphical interface 202 transmits the export command to the control unit 300. After receiving the command, the control unit 300 immediately starts the data export program and sends a display adjustment command to the first graphical interface 201.

[0050] After receiving the display adjustment command, the first graphical interface 201 immediately hides the temperature trend chart (located in the middle left of the interface, with a size of 200×150 pixels), the gas depth icon (located in the upper right of the interface, with a size of 50×50 pixels), and the liquid depth icon (located in the middle right of the interface, with a size of 50×50 pixels). Only the four-dimensional real-time data display area for intra-abdominal pressure, intra-abdominal temperature, gas depth, and liquid depth is retained in the upper half of the interface, occupying 50% of the area, and the export progress prompt area is located in the lower half of the interface, occupying 50% of the area. The export progress prompt area displays the progress percentage synchronized with the second graphical interface 202 and the text prompt "Data export in progress, please wait" in SimSun font, size 14, and black RGB: 0,0,0.

[0051] When the data export completion percentage reaches 100%, the control unit 300 sends a recovery command to the first graphical interface 201. The first graphical interface 201 restores its full display, that is, it redisplays the hidden temperature trend chart, gas depth icon, and liquid depth icon. At the same time, a pop-up export success prompt box appears, with a size of 300×150 pixels, a white background color, and a green border color (RGB:0,128,0). The prompt box displays the text "Data export successful!" in SimSun font, size 16, and black (RGB:0,0,0). The prompt box closes automatically after 5 seconds. Medical staff can close it immediately by clicking the close button on the prompt box.

[0052] The exported data is stored in Excel format on storage devices associated with the second graphical interface 202, such as the terminal's internal storage, external USB flash drive, or cloud storage. The filename format is "Detection Data_Export Time_Patient Number," with the export time format being year-month-day-hour-minute-second. The patient number is a unique identifier pre-entered by medical staff. During the data export process, the progress is displayed synchronously on both interfaces, allowing medical staff to monitor the export status in real time and avoid repetitive operations. The first graphical interface 201 hides unnecessary elements during the export process, highlighting core data and progress prompts to improve the relevance of information display. The successful export prompt and standardized file naming format facilitate confirmation of export results and subsequent data retrieval and archiving by medical staff, enhancing the convenience of data management.

[0053] Furthermore, the operation instructions of the second graphical interface 202 include modifying the monitoring frequency. Medical staff can modify the monitoring frequency on the second graphical interface 202 according to monitoring needs, such as decreasing the frequency when the condition is stable and increasing the frequency when the condition is unstable. The specific operation process and dual-interface response are as follows: Medical staff click the monitoring frequency option in the settings menu of the second graphical interface 202 to enter the monitoring frequency selection interface; the monitoring frequency selection interface displays 5 selectable frequencies: 1 time / 5 minutes, 1 time / 1 minute, 1 time / 30 seconds, 1 time / 10 seconds, and 1 time / 5 seconds. Each frequency option corresponds to a selection box with a size of 20×20 pixels. The default selected frequency is 1 time / 1 minute. An orange border with RGB: 255,165,0 is displayed next to the selected frequency option, and the border width is 2 pixels; Medical staff The operator clicks the selection box corresponding to the target frequency to complete the monitoring frequency modification. After modification, an orange border appears next to the target frequency option, and the orange border of the originally selected frequency option disappears. The operation of the second graphical interface 202 changes to monitoring frequency update. A temporary prompt box pops up at the top of the interface, with a size of 200×50 pixels, an orange background color (RGB: 255,165,0), and displays the text "The monitoring frequency has been updated to XX" in SimSun font, size 12, and white color (RGB: 255,255,255). The prompt box disappears automatically after 3 seconds. The second graphical interface 202 transmits the modified monitoring frequency command to the control unit 300. After receiving it, the control unit 300 immediately updates the acquisition frequency parameters of the acquisition unit 100 and simultaneously synchronizes the command to the first graphical interface 201.

[0054] After receiving the monitoring frequency command, the first graphical interface 201 displays the current monitoring frequency in the upper right corner of the interface, in a 100×30 pixel status display area. For example, the monitoring frequency is 1 time / 30 seconds, the font is SimSun, font size 12, and the color is black (RGB: 0,0,0). Simultaneously, the refresh cycle for both detection and verification data is adjusted, ensuring it perfectly matches the selected monitoring frequency. That is, when the monitoring frequency is 1 time / 5 minutes, the data refresh cycle is 5 minutes; when the monitoring frequency is 1 time / 10 seconds, the data refresh cycle is 10 seconds, ensuring the displayed data is synchronized with the acquisition frequency and reflects the latest monitoring results in real time. Flexible adjustment of the monitoring frequency is supported to adapt to the monitoring needs of different disease stages. Lowering the frequency when the condition is stable reduces data redundancy, while increasing the frequency when the condition is unstable captures subtle changes. The synchronized frequency updates and status display across both interfaces ensure that medical staff clearly understand the current monitoring pace, and the consistency between the data refresh cycle and the monitoring frequency guarantees the real-time and accurate display of the data.

[0055] Furthermore, the visual interaction effect parameters of the second graphical interface 202 include the flashing frequency, which is positively correlated with the fluctuation amplitude of the abdominal wall tension data. The specific correlation is as follows: the fluctuation amplitude of the abdominal wall tension data is calculated by the control unit 300. The calculation method is: with a period of 1 minute, the difference between the maximum and minimum values ​​of the abdominal wall tension within that period is taken as the fluctuation amplitude of the abdominal wall tension data, with the unit being N / m. The relationship between the flashing frequency of the intra-abdominal pressure value and the amplitude of abdominal wall tension fluctuation in the second graphical interface 202 is as follows: When the amplitude of abdominal wall tension fluctuation is ≤0.5N / m, the intra-abdominal pressure value does not flash and remains constantly lit, with a green or red color, depending on whether it exceeds the safety threshold; when the amplitude of abdominal wall tension fluctuation is between 0.5 and 1.0N / m, the intra-abdominal pressure value flashes 1 time / second; when the amplitude of abdominal wall tension fluctuation is between 1.0 and 1.5N / m, the intra-abdominal pressure value flashes 2 times / second; when the amplitude of abdominal wall tension fluctuation is >1.5N / m, the intra-abdominal pressure value flashes 3 times / second. For example, if the maximum value of abdominal wall tension within one minute is 3.0N / m and the minimum value is 1.2N / m, with a fluctuation amplitude of 1.8N / m, then the flashing frequency of the intra-abdominal pressure value in the second graphical interface 202 is 3 times / second. The change in flashing frequency visually reflects the fluctuation of abdominal wall tension, assisting medical staff in judging the reliability of intra-abdominal pressure data and the stability of the newborn's abdominal condition. By correlating the fluctuation amplitude of abdominal wall tension with the flashing frequency of intra-abdominal pressure values, a visual linkage between verification and detection data is achieved. Medical staff can quickly determine the fluctuation of abdominal wall tension through the flashing frequency, thereby assessing the accuracy of intra-abdominal pressure data. At the same time, it provides an additional reference dimension for judging the abdominal condition of newborns, improving the comprehensiveness and reliability of monitoring.

[0056] To facilitate understanding of the technical solution of this invention, its working process is briefly described below: After the device is started, the acquisition unit 100 is initialized, and the pressure sensor, temperature sensor, ultrasonic detection module and tension sensor are started synchronously. The device starts to collect detection data such as intra-abdominal pressure, abdominal temperature, gas depth, and fluid depth, as well as abdominal wall tension verification data at the default monitoring frequency of 1 time / minute. The collected data is transmitted to the control unit 300 in real time. After receiving the data, the control unit 300 preprocesses the data, such as removing interference signals and calibrating the numerical accuracy, and compares the detection data with the built-in safety threshold and the preset threshold for the rate of change in real time. If the detection data does not trigger the safety threshold, the first graphical interface 201 continuously displays the real-time values, trend charts and corresponding icons of each detection data, while the second graphical interface 202 is in standby mode, displaying the main menu and the current monitoring status. If the detected data triggers a safety threshold, the control unit 300 identifies the anomaly type as single data anomaly, composite data anomaly, or data co-movement anomaly, and sends a status change command to the first graphical interface 201. The first graphical interface 201 provides an anomaly warning through color changes, numerical flashing, icon flashing, and other means. At the same time, the control unit 300 triggers the second graphical interface 202 to establish a corresponding category directory, automatically storing the associated detection data, historical data, and verification data into the directory, and strengthening the warning through visual interaction forms such as vibration feedback and flashing frequency changes. Medical staff can view abnormal data and storage directories through the second graphical interface 202 and input operation commands as needed: If the safety threshold is adjusted, the second graphical interface 202 displays feedback on the completion of the modification, and the control unit 300 simultaneously updates the warning rules and color indicators of the first graphical interface 201; if data export is triggered, the second graphical interface 202 displays the export progress, the first graphical interface 201 hides unnecessary elements and displays a progress prompt, and restores the full display and pops up a success prompt after the export is completed; if the monitoring frequency is modified, the second graphical interface 202 displays an update prompt, the control unit 300 adjusts the acquisition frequency of the acquisition unit 100, and the first graphical interface 201 displays the current frequency and simultaneously adjusts the data refresh cycle; Throughout the entire operation, the visual interaction parameters of the second graphical interface 202, such as flashing frequency and vibration frequency, are positively correlated with the detection data parameters, such as exceeding the threshold and fluctuation amplitude. The two interfaces achieve real-time data synchronization and coordinated operation response through the control unit 300, ensuring the continuity, accuracy, and ease of operation of the monitoring process. When the device is turned off, the control unit 300 automatically saves all collected data to local storage, and can also back up the data to the cloud according to preset settings to ensure that the data is not lost.
