Description

Technical Field

[0001] This application relates to the technical field, and in particular to methods for indicating maternal-fetal heart rate overlap, maternal-fetal monitoring equipment, systems, and storage media. Background Technology

[0002] During maternal-fetal monitoring, the raw signals collected by the signal acquisition device are processed to obtain the fetal heart rate and the mother's heart rate. However, due to factors such as fetal movement, maternal blood flow, and relative movement of the signal acquisition device during the monitoring process, the signal acquisition device may make erroneous acquisitions. Instead of measuring the mother's heart rate and the fetal heart rate separately, the heart rate of the same object is measured, resulting in the overlap of maternal and fetal heart rates.

[0003] In related technologies, when detecting maternal-fetal overlap, the mother's heart rate and the fetal heart rate are usually calculated, and their consistency is compared to determine whether maternal-fetal overlap exists (e.g., comparing the magnitudes of the mother's and fetal heart rates). When overlap is detected, a heart rate overlap alarm is triggered. However, both fetal and maternal heart rates are calculated results. If the original signal quality is poor or other technical reasons prevent obtaining a valid and accurate heart rate calculation result, an accurate determination of maternal-fetal overlap cannot be made. This prevents medical personnel from timely and accurately understanding the physiological condition of the pregnant woman and fetus. Summary of the Invention

[0004] The maternal-fetal heart rate overlap detection method, maternal-fetal monitoring equipment, system, and storage medium provided in this application can improve the accuracy of maternal-fetal overlap detection.

[0005] In a first aspect, this application provides a method for indicating maternal-fetal heart rate overlap, the method comprising: generating a maternal-fetal overlap rate based on the collected original maternal physiological signals and original fetal physiological signals; and displaying maternal-fetal overlap information on a visualization interface, the maternal-fetal overlap information including at least the maternal-fetal overlap rate.

[0006] Among them, the original maternal physiological signals include any one of the maternal electrocardiogram signals, maternal heart sound signals, and maternal pulse signals, and the original fetal physiological signals include any one of the fetal electrocardiogram signals and fetal heart sound signals.

[0007] The maternal-fetal overlap information also includes identification information corresponding to the maternal-fetal overlap rate, which includes text names and / or graphic symbols.

[0008] The visualization interface includes at least a main interface, which includes a first display area. The visualization interface displays maternal-fetal overlap information, including: displaying the maternal-fetal overlap rate in real time in the first display area.

[0009] The maternal-fetal overlap information also includes the identification information corresponding to the maternal-fetal overlap rate; the display of maternal-fetal overlap information on the visualization interface also includes: displaying the identification information corresponding to the maternal-fetal overlap rate in real time in the first display area.

[0010] The visualization interface includes at least a main interface, which includes a fetal parameter display area and a first display area. The fetal parameter display area contains the first display area. The fetal parameter display area is used to display the physiological parameters of the fetus, and the first display area is used to display the maternal-fetal overlap information corresponding to the first target fetus, which is a singleton.

[0011] The visualization interface includes at least a main interface, which includes multiple fetal parameter display areas and a first display area. The first display area includes multiple sub-display areas, and each fetal parameter display area contains one sub-display area. Each fetal parameter display area is used to display the physiological parameters of the second target fetus, and the sub-display areas contained in each fetal parameter display area are used to display the maternal-fetal overlap information corresponding to the second target fetus. The second target fetus is any one of the fetuses in a multiple pregnancy.

[0012] The visualization interface includes at least a main interface, which includes a first display area that displays maternal-fetal overlap information corresponding to the third target fetus. The first display area is located in the top right area of ​​the main interface, and the third target fetus is any fetus in a singleton or multiple pregnancy.

[0013] The process of displaying maternal-fetal overlap information on the visualization interface includes: detecting the user's setting operation for the display mode, determining the selected display mode based on the setting operation, and displaying the maternal-fetal overlap information on the visualization interface according to the selected display mode.

[0014] The visualization interface includes a main interface and a secondary menu interface. The main interface includes a first display area, and the display modes include a first display mode, a second display mode, or a third display mode. The visualization interface displays maternal-fetal overlap information according to the selected display mode, including: if the selected display mode is the first display mode, the maternal-fetal overlap information is displayed in real-time in the first display area of ​​the main interface; if the selected display mode is the second display mode, the maternal-fetal overlap information is displayed in the target area of ​​the secondary menu interface when the visualization interface switches to the secondary menu interface; if the selected display mode is the third display mode, the maternal-fetal overlap information is displayed in the first display area of ​​the main interface when an abnormal maternal-fetal overlap rate is detected.

[0015] The method also includes: when an abnormal maternal-fetal overlap rate is detected, displaying overlap alarm information for the abnormal maternal-fetal overlap rate.

[0016] The visualization interface includes a main interface, which includes a second display area. The overlap alarm information includes text alarm information. The overlap alarm information is displayed for abnormal maternal-fetal overlap rates, including: for abnormal maternal-fetal overlap rates, text alarm information is displayed in the second display area.

[0017] The visualization interface includes a main interface, which includes a first display area for displaying maternal-fetal overlap information, including maternal-fetal overlap rate and / or, identification information corresponding to the maternal-fetal overlap rate. For abnormal maternal-fetal overlap rates, an overlap alarm message is displayed. The interface further includes: flashing the abnormal maternal-fetal overlap rate in the first display area; and / or magnifying the abnormal maternal-fetal overlap rate in the first display area; and / or displaying the abnormal maternal-fetal overlap rate in the first display area with a preset color, wherein the preset color is different from the color corresponding to the normal maternal-fetal overlap rate; and / or highlighting the identification information corresponding to the abnormal maternal-fetal overlap rate in the first display area.

[0018] The method further includes the following steps before displaying an overlap alarm message when an abnormal maternal-fetal overlap rate is detected: if the maternal-fetal overlap rate is greater than a first preset value, comparing the changing trends between the original maternal physiological signals and the original fetal physiological signals; if the changing trends are consistent, determining that the maternal-fetal overlap rate is abnormal; if the changing trends are inconsistent, determining that the maternal-fetal overlap rate is normal.

[0019] The process of generating maternal-fetal overlap rate based on the collected original maternal and fetal physiological signals includes: performing homology analysis on the collected original maternal and fetal physiological signals to obtain multiple correlations; and generating maternal-fetal overlap rate based on the multiple correlations.

[0020] The process of generating maternal-fetal overlap rate based on multiple correlations includes: obtaining all correlations within a preset time period from multiple correlations; determining a target correlation from all correlations; wherein the target correlation is greater than a second preset value; and generating the maternal-fetal overlap rate based on the number of target correlations.

[0021] The process of generating maternal-fetal overlap rate based on the number of target relevances includes: using the ratio between the number of target relevances and the number of all relevances as the maternal-fetal overlap rate.

[0022] The method further includes: responding to an adjustment command by outputting a position adjustment prompt; wherein the adjustment command is generated when there is an abnormality in the maternal-fetal overlap rate and the preset conditions are met, and the position adjustment prompt is used to instruct the user to adjust the current position of the signal acquisition device, and the signal acquisition device is used to acquire raw maternal physiological signals and / or raw fetal physiological signals.

[0023] Secondly, this application provides a maternal-fetal monitoring device, which includes: a signal acquisition device for acquiring raw maternal physiological signals and raw fetal physiological signals; a memory for storing a computer program; a processor coupled to the memory and the signal acquisition device for executing the computer program to implement the method provided in the first aspect; and a display screen coupled to the processor for displaying a visual interface.

[0024] Thirdly, this application provides a central monitoring system, which includes: at least one maternal-fetal monitoring device as provided in the second aspect; a central station, communicatively connected to the maternal-fetal monitoring device, including at least a processor and a display, wherein the processor receives and processes data sent by the maternal-fetal monitoring device.

[0025] Fourthly, this application provides a computer storage medium for storing a computer program that, when executed by a processor, implements the method provided in the first aspect.

[0026] The beneficial effects of this application are as follows: Unlike the prior art, the maternal-fetal heart rate overlap indication method, maternal-fetal monitoring equipment, system, and storage medium provided in this application generate a maternal-fetal overlap rate based on the collected original maternal and fetal physiological signals. On the one hand, this avoids the problem that when judging whether maternal-fetal signals overlap by using fetal and maternal heart rates, the inability to obtain a valid and correct heart rate calculation result due to technical reasons leads to an inaccurate judgment of maternal-fetal overlap, thereby improving the accuracy of maternal-fetal overlap judgment. On the other hand, compared to judging whether maternal-fetal signals overlap by using fetal and maternal heart rates, the poor quality of the original signals easily leads to inaccurate heart rate calculations, resulting in inaccurate maternal-fetal overlap judgment results. This application obtains a more accurate maternal-fetal overlap judgment result by directly comparing and calculating the two original signals and comprehensively judging and calculating based on the various information reflected in the original signals.

[0027] Furthermore, the solution disclosed in this application can calculate the specific maternal-fetal overlap rate and display it on a visual interface. In related technologies, the existence of maternal-fetal overlap can only be determined based on the mother's heart rate and the fetal heart rate, and an alarm is triggered if it exists, but the degree of maternal-fetal overlap is not reflected. False alarms may occur when the maternal and fetal heart rates are close. To confirm whether the current alarm is a false alarm or a real alarm, medical staff need to manually compare the maternal and fetal heart rate data from a previous period to confirm whether maternal-fetal overlap has actually occurred. The solution disclosed in this application can clearly inform medical staff of the current maternal-fetal overlap rate. When a maternal-fetal overlap alarm occurs, the magnitude of the maternal-fetal overlap rate can determine whether it is a false alarm or a real alarm. When the value is large (e.g., 0.8, 0.9, etc.), it can be directly confirmed that the degree of maternal-fetal overlap is very strong and it is unlikely to be a false alarm. This reduces the number or frequency of manual data comparisons by medical staff, thereby saving manpower, reducing the workload of medical staff, and improving their efficiency.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] 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.

[0044] During maternal-fetal monitoring, the raw signals collected by the signal acquisition device are processed to obtain the fetal heart rate and the mother's heart rate. However, due to factors such as fetal movement, maternal blood flow, and relative movement of the signal acquisition device during the monitoring process, the signal acquisition device may make erroneous acquisitions. Instead of measuring the mother's heart rate and the fetal heart rate separately, the heart rate of the same object is measured, resulting in the overlap of maternal and fetal heart rates.

[0045] In related technologies, when detecting maternal-fetal overlap, the mother's heart rate and the fetal heart rate are usually calculated, and their consistency is compared to determine whether maternal-fetal overlap exists (e.g., comparing the magnitudes of the mother's and fetal heart rates). When overlap is detected, a heart rate overlap alarm is triggered. However, both fetal and maternal heart rates are calculated results. If the original signal quality is poor or other technical reasons prevent obtaining a valid and accurate heart rate calculation result, an accurate determination of maternal-fetal overlap cannot be made. This prevents medical personnel from timely and accurately understanding the physiological condition of the pregnant woman and fetus.

[0046] Based on this, this application proposes to generate maternal-fetal overlap rate based on the collected original maternal and fetal physiological signals. On the one hand, this avoids the problem that when judging whether maternal-fetal signals overlap by using fetal and maternal heart rates, the inability to obtain a valid and correct heart rate calculation result due to technical reasons leads to an inaccurate judgment of maternal-fetal overlap, thereby improving the accuracy of maternal-fetal overlap judgment. On the other hand, compared to judging whether maternal-fetal signals overlap by using fetal and maternal heart rates, the poor quality of the original signals is prone to miscalculation of heart rate, resulting in inaccurate heart rate values ​​and thus inaccurate maternal-fetal overlap judgment results. This application obtains a more accurate maternal-fetal overlap judgment result by directly comparing and calculating the two original signals and comprehensively judging and calculating based on the various information reflected in the original signals.

[0047] Furthermore, the solution disclosed in this application can calculate the specific maternal-fetal overlap rate and display it on a visual interface. In related technologies, only the presence of maternal-fetal overlap can be determined based on the mother's and fetal heart rates; if it exists, an alarm is triggered, but the degree of overlap is not shown. False alarms may occur when the maternal and fetal heart rates are close. To confirm whether the alarm is a false alarm or a real alarm, medical staff need to manually compare maternal and fetal heart rate data from a previous period to verify the actual occurrence of maternal-fetal overlap. The solution disclosed in this application clearly informs medical staff of the current maternal-fetal overlap rate. When a maternal-fetal overlap alarm occurs, the magnitude of the overlap rate determines whether to confirm whether the alarm is a false alarm or a real alarm. When the value is large (e.g., 0.8, 0.9, etc.), it can be directly confirmed that the degree of maternal-fetal overlap is very strong and it is unlikely to be a false alarm. This reduces the number or frequency of manual data comparisons by medical staff, thereby saving manpower, reducing the workload of medical staff, and improving their efficiency. See any of the following embodiments for details.

[0048] See Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the maternal-fetal heart rate overlap detection method provided in this application. The method includes:

[0049] Step 11: Generate maternal-fetal overlap rate based on the collected original maternal physiological signals and original fetal physiological signals.

[0050] Specifically, the maternal-fetal overlap rate is used to indicate the degree of overlap or consistency between the mother's heart rate and the fetal heart rate. Optionally, the maternal-fetal overlap rate can be generated directly using the original maternal and fetal physiological signals. However, considering that during the monitoring of pregnant women, factors such as body movement, intestinal peristalsis, and uterine contractions can cause the probe to move relative to the body, thus interfering with the signal, in order to reduce the impact of interference on the signal, in some embodiments, interference suppression processing, such as filtering, is first applied to the original maternal and fetal physiological signals. Then, the maternal-fetal overlap rate is generated based on the processed original maternal and fetal physiological signals to improve the signal-to-noise ratio and thus improve the accuracy of the obtained maternal-fetal overlap rate.

[0051] In some embodiments, the original maternal physiological signal includes any one of the maternal electrocardiogram (ECG) signal, maternal heart sound signal, and maternal pulse signal; the original fetal physiological signal includes any one of the fetal ECG signal and fetal heart sound signal, and this application is not limited thereto. However, considering the reliability and convenience of signal acquisition, it is preferable to use the maternal ECG signal as the original maternal physiological signal and the fetal heart sound signal as the original fetal physiological signal, so that the required signal can be acquired using existing signal acquisition devices, thereby saving medical equipment costs while ensuring the reliability of the original signal and the convenience of operation for medical staff.

[0052] Specifically, the acquisition of primitive maternal physiological signals and primitive fetal physiological signals can be achieved through a signal acquisition device. The signal acquisition device sends the acquired signals to the monitoring equipment, and the signal acquisition device and the monitoring equipment can communicate with each other via wired or wireless means.

[0053] Optionally, the signal acquisition device can simultaneously acquire raw maternal physiological signals and raw fetal physiological signals. For example, the signal acquisition device is a fetal electrocardiogram probe on the body surface, which, when used with electrocardiogram lead wires, can acquire maternal electrocardiogram signals and fetal electrocardiogram signals in real time through the pregnant woman's body surface electrocardiogram technology, thereby generating the maternal-fetal overlap rate through the maternal electrocardiogram signals and fetal electrocardiogram signals.

[0054] Optionally, the signal acquisition device may include two independent signal acquisition units to acquire the original maternal physiological signals and the original fetal physiological signals respectively. Therefore, in some embodiments, the signal acquisition device includes an independent first signal acquisition unit and a second signal acquisition unit. The first signal acquisition unit can be used to acquire the original maternal physiological signals, and the second signal acquisition unit can be used to acquire the original fetal physiological signals. For example, the first signal acquisition unit may be an electrocardiogram (ECG) probe to acquire the maternal ECG signal. The ECG probe may be a uterine contraction pressure probe with ECG electrodes, a separate ECG electrode, or an ECG lead wire. The first signal acquisition unit may also be a pulse oximeter to acquire the maternal pulse signal. Optionally, the second signal acquisition unit may be an ultrasound probe to acquire the fetal heart sound signal; this application is not limited to this.

[0055] Step 12: Display maternal-fetal overlap information on the visualization interface. The maternal-fetal overlap information includes at least the maternal-fetal overlap rate.

[0056] Specifically, the visualization interface can be directly installed on the maternal-fetal monitoring device; that is, a display screen can be set on the maternal-fetal monitoring device to provide the corresponding visualization interface. Optionally, an external monitor can be connected to the maternal-fetal monitoring device to display the visualization interface. Optionally, the visualization interface can be displayed on a monitor configured in a central monitoring system, which can receive monitoring information sent by multiple maternal-fetal monitoring devices, and the monitoring information includes at least the maternal-fetal overlap rate.

[0057] The scheme disclosed in this embodiment can generate maternal-fetal overlap rate based on the collected original maternal and fetal physiological signals. On the one hand, it can avoid the problem that when judging whether maternal-fetal signals overlap by using fetal and maternal heart rates, the heart rate calculation result cannot be obtained due to technical reasons, thus failing to make an accurate judgment on maternal-fetal overlap, thereby improving the accuracy of maternal-fetal overlap judgment. On the other hand, compared with judging whether maternal-fetal signals overlap by using fetal and maternal heart rates, the poor quality of the original signals is prone to miscalculation of heart rate, resulting in inaccurate heart rate values ​​and thus failing to obtain an accurate maternal-fetal overlap judgment result. This application obtains a more accurate maternal-fetal overlap judgment result by directly comparing and calculating the two original signals and comprehensively judging and calculating based on the various information reflected in the original signals.

[0058] Furthermore, the solution disclosed in this embodiment can calculate the specific maternal-fetal overlap rate and display it on a visual interface. In related technologies, the existence of maternal-fetal overlap can only be determined based on the mother's heart rate and the fetal heart rate. If overlap is found, an alarm is triggered, but the degree of overlap is not reflected. False alarms may occur when the maternal and fetal heart rates are close. To confirm whether the current alarm is a false alarm or a real alarm, medical staff need to manually compare the maternal and fetal heart rate data from a previous period to verify the actual occurrence of maternal-fetal overlap. The solution disclosed in this application clearly informs medical staff of the current maternal-fetal overlap rate. When a maternal-fetal overlap alarm occurs, the magnitude of the overlap rate determines whether to confirm whether the alarm is a false alarm or a real alarm. When the value is large (e.g., 0.8, 0.9, etc.), it can be directly confirmed that the degree of maternal-fetal overlap is very strong and it is unlikely to be a false alarm. This reduces the number or frequency of manual data comparisons by medical staff, thereby saving manpower, reducing their workload, and improving their efficiency.

[0059] In some embodiments, the maternal-fetal overlap information also includes identification information corresponding to the maternal-fetal overlap rate, which includes a text name. That is, at least the maternal-fetal overlap rate and its corresponding text name are displayed on the visualization interface. The text name can be an English abbreviation, used to indicate that the parameter is the maternal-fetal overlap rate. Optionally, the maternal-fetal overlap information also includes identification information corresponding to the maternal-fetal overlap rate, which includes a graphic identifier. That is, at least the maternal-fetal overlap rate and its corresponding graphic identifier are displayed on the visualization interface, used to indicate that the parameter is the maternal-fetal overlap rate. Optionally, the maternal-fetal overlap information also includes identification information corresponding to the maternal-fetal overlap rate, which includes a text name and a graphic identifier. Thus, by displaying the graphic identifier and the maternal-fetal overlap rate, or the text name and the maternal-fetal overlap rate, or the text name, graphic identifier, and maternal-fetal overlap rate, the user can intuitively understand the specific meaning of the parameter.

[0060] Specifically, the graphic identifier can be at least one recognizable shape, such as a circle, polygon, or teardrop, or a pre-designed pattern related to the parameters. Optionally, the monitoring device can monitor singletons or multiples. When monitoring multiples, each fetus can have a separate graphic identifier and / or a text name. Optionally, the graphic identifier can also be used to indicate the degree of maternal-fetal overlap. When the maternal-fetal overlap rate is high, the color-filled area in the graphic identifier is also large; when the maternal-fetal overlap rate is low, the color-filled area in the graphic identifier is also small. For example, if the maternal-fetal overlap rate is 0.8, the teardrop-shaped graphic identifier is filled with color for four-fifths; if the maternal-fetal overlap rate is 0.4, the teardrop-shaped graphic identifier is filled with color for two-fifths.

[0061] In an optional embodiment, the visualization interface includes at least a main interface, which includes a first display area, and the first display area displays the maternal-fetal overlap rate in real time. (Specifically combined with...) Figure 2 Explanation:

[0062] The main interface A includes a first display area B, in which the maternal-fetal overlap rate is displayed in real time. Other content can be displayed in other non-first display areas B of the main interface A, such as fetal heart rate curve, maternal heart rate curve, TOCO curve, fetal heart rate value, maternal heart rate value, uterine contraction pressure value, maternal electrocardiogram waveform, blood oxygen, respiratory rate, body temperature, etc.

[0063] In another optional embodiment, the visualization interface includes at least a main interface, which includes a first display area where the identification information corresponding to the maternal-fetal overlap rate is displayed in real time. Combined with... Figure 3 Explanation:

[0064] The main interface A includes a first display area B, in which the identification information C corresponding to the maternal-fetal overlap rate is displayed in real time. Optionally, the maternal-fetal overlap rate and the identification information C can be displayed in real time simultaneously in the first display area B, or only the identification information C can be displayed in real time. If the user needs to view the maternal-fetal overlap rate, they can click on the identification information C on the main interface to display the current maternal-fetal overlap rate on the visual interface.

[0065] In another optional embodiment, the visualization interface includes at least a main interface, which includes a fetal parameter display area and a first display area, wherein the fetal parameter display area includes the first display area; wherein the fetal parameter display area is used to display the physiological parameters of the fetus, and the first display area is used to display maternal-fetal overlap information corresponding to the first target fetus, wherein the first target fetus is a singleton. Figure 4 Explanation:

[0066] The main interface A includes a first display area B and a fetal parameter display area D. The first display area B is contained within the fetal parameter display area D. The fetal parameter display area D displays the fetus's physiological parameters, such as fetal heart rate, fetal heart signal quality parameters, and fetal heart rate refresh rate parameters. The first display area B displays the maternal-fetal overlap information corresponding to the first target fetus, which is a singleton pregnancy. By linking the maternal-fetal overlap information with the display area of ​​the fetal physiological parameters, the information display becomes more intuitive, and it is more convenient for medical staff to view the information.

[0067] In another optional embodiment, the visualization interface includes at least a main interface, which includes multiple fetal parameter display areas and a first display area. The first display area includes multiple sub-display areas, and each fetal parameter display area contains one sub-display area. Each fetal parameter display area is used to display the physiological parameters of the second target fetus, and the sub-display areas within each fetal parameter display area are used to display maternal-fetal overlap information corresponding to the second target fetus. The second target fetus is any one of the fetuses in a multiple pregnancy. Figure 5 Explanation:

[0068] The main interface A includes a first display area B, a fetal parameter display area E, a fetal parameter display area F, and a fetal parameter display area G. The first display area B includes a first sub-display area b1, a second sub-display area b2, and a third sub-display area b3. Fetal parameter display area E contains the first sub-display area b1, fetal parameter display area F contains the second sub-display area b2, and fetal parameter display area G contains the third sub-display area b3.

[0069] The fetal parameter display area E displays the physiological parameters of the first fetus. The first sub-display area b1 displays the maternal-fetal overlap information corresponding to the first fetus. The fetal parameter display area F displays the physiological parameters of the second fetus. The second sub-display area b2 displays the maternal-fetal overlap information corresponding to the second fetus. The fetal parameter display area G displays the physiological parameters of the third fetus. The third sub-display area b3 displays the maternal-fetal overlap information corresponding to the third fetus. When monitoring multiple pregnancies, by associating the maternal-fetal overlap information corresponding to each fetus with the display area of ​​its physiological parameters, medical staff can quickly and intuitively match the maternal-fetal overlap information with the fetuses. This prevents medical staff from mistakenly focusing on or adjusting the wrong fetus when a maternal-fetal overlap is detected, or when adjusting the signal acquisition device corresponding to that fetus.

[0070] In another optional embodiment, the visualization interface includes at least a main interface, which includes a first display area displaying maternal-fetal overlap information corresponding to the third target fetus. The first display area is located at the top right of the main interface, and the third target fetus is any fetus in a singleton or multiple pregnancy. Specifically, the maternal-fetal overlap information displayed in the first display area B is determined by the number of fetuses in the current mother. For a singleton pregnancy, the first display area B displays the maternal-fetal overlap information corresponding to the singleton. For twins, the first display area B displays the maternal-fetal overlap information corresponding to both fetuses. For triplets, the first display area B displays the maternal-fetal overlap information corresponding to all three fetuses.

[0071] Combination Figure 6 Explanation:

[0072] The main interface A includes a first display area B, which displays the maternal-fetal overlap information corresponding to the third target fetus. Specifically, the first display area B is located at the top right of the main interface A, and it displays the maternal-fetal overlap information corresponding to the first, second, and third fetuses.

[0073] In some embodiments, the method for displaying maternal-fetal overlap information on the visualization interface can be as follows: detecting the user's setting operation for the display mode, determining the selected display mode based on the setting operation, and displaying the maternal-fetal overlap information on the visualization interface according to the selected display mode. That is, the user can customize the area where the maternal-fetal overlap information is displayed, when the maternal-fetal overlap information is displayed, and which maternal-fetal overlap information is displayed, etc. Based on this, by providing a customizable display mode, the display methods of maternal-fetal overlap information can be increased and different user display needs can be met.

[0074] For example, the visual interface includes a main interface and a secondary menu interface. The main interface includes a first display area, and the display mode includes a first display mode, a second display mode, or a third display mode.

[0075] Optionally, if the selected display mode is the first display mode, the maternal-fetal overlap information will be displayed in real time in the first display area of ​​the main interface.

[0076] Optionally, if the selected display mode is the second display mode, then when the visualization interface switches to the secondary menu interface, the maternal-fetal overlap information is displayed in the target area of ​​the secondary menu interface. This secondary menu interface display method eliminates the need for display on the main interface, reducing its footprint, and provides the necessary viewing functionality. It allows the information to be displayed on the secondary menu interface when the user needs to view the maternal-fetal overlap information.

[0077] Optionally, if the selected display mode is the third display mode, then when an abnormality in the maternal-fetal overlap rate is detected, the maternal-fetal overlap information will be displayed in the first display area of ​​the main interface. When the maternal-fetal overlap rate is normal, the maternal-fetal overlap information can be displayed or not displayed in the target area of ​​the secondary menu interface.

[0078] If no user setting operation for display mode is detected, the first display mode can be used by default, and the maternal-fetal overlap information will be displayed in real time in the first display area of ​​the main interface.

[0079] See Figure 7 , Figure 7 This is a flowchart illustrating another embodiment of the maternal-fetal heart rate overlap detection method provided in this application. The method includes:

[0080] Step 71: Generate maternal-fetal overlap rate based on the collected original maternal physiological signals and original fetal physiological signals.

[0081] Step 72: Display maternal-fetal overlap information on the visualization interface. The maternal-fetal overlap information includes at least the maternal-fetal overlap rate.

[0082] Step 73: When an abnormal maternal-fetal overlap rate is detected, an overlap alarm message is displayed for the abnormal maternal-fetal overlap rate.

[0083] In some embodiments, the generated maternal-fetal overlap rate can be detected for abnormalities in real time. When an abnormality is detected in the maternal-fetal overlap rate, an overlap alarm message is displayed for the abnormal maternal-fetal overlap rate. The overlap alarm message is used to indicate that the degree of overlap or consistency between the maternal heart rate and the fetal heart rate exceeds a preset normal threshold.

[0084] In some embodiments, the visualization interface includes a main interface, which includes a second display area. Specifically, the second display area and the first display area can be different areas. For example, the second display area may be the same as the alarm area where the monitoring device performs physiological or technical alarms. The overlap alarm information includes text alarm information. When an abnormal maternal-fetal overlap rate is detected, text alarm information is displayed in the second display area for the abnormal maternal-fetal overlap rate. For example, the text alarm information may include "Maternal-fetal signal overlap". When the monitored object is a multiple pregnancy, if the heart rate of the first fetus overlaps with the mother's heart rate, the text alarm information "Maternal-fetal signal overlap (fetal heart rate 1)" can be output.

[0085] In other embodiments, text alarm information can be displayed in a scrolling manner on the main interface, increasing the display ratio of text alarm information on the main interface and increasing the probability that text alarm information can be viewed.

[0086] In some embodiments, the visualization interface includes a main interface, which includes a first display area for displaying maternal-fetal overlap information, including the maternal-fetal overlap rate.

[0087] Optionally, when an abnormal maternal-fetal overlap rate is detected, the abnormal maternal-fetal overlap rate is flashed in the first display area. For example, the abnormal maternal-fetal overlap rate is flashed in the first display area at a preset flashing frequency, thereby informing the user that the maternal-fetal overlap rate is abnormal through a conspicuous flashing method and triggering an overlap alarm.

[0088] Optionally, when an abnormal maternal-fetal overlap rate is detected, the abnormal maternal-fetal overlap rate is enlarged and displayed in the first display area. For example, the abnormal maternal-fetal overlap rate is enlarged and displayed in the first display area according to a preset magnification ratio, thereby informing the user that the maternal-fetal overlap rate is abnormal and triggering a corresponding overlap alarm.

[0089] Optionally, when an abnormal maternal-fetal overlap rate is detected, the abnormal maternal-fetal overlap rate is displayed in a preset color in the first display area. This preset color differs from the color corresponding to the normal maternal-fetal overlap rate. For example, if the preset color is red, the color corresponding to the normal maternal-fetal overlap rate is green. When an abnormal maternal-fetal overlap rate is detected, the abnormal maternal-fetal overlap rate is displayed in red in the first display area, thus informing the user of the abnormal maternal-fetal overlap rate through color change and triggering an appropriate overlap alarm.

[0090] Optionally, the maternal-fetal overlap information also includes identification information corresponding to the maternal-fetal overlap rate. When an abnormal maternal-fetal overlap rate is detected, the identification information corresponding to the abnormal maternal-fetal overlap rate is highlighted in the first display area. This identification information can indicate that the current maternal-fetal overlap rate is abnormal. Therefore, by displaying the identification information indicating the abnormal maternal-fetal overlap rate, the user can be informed that the maternal-fetal overlap rate is abnormal, and a corresponding overlap alarm can be triggered.

[0091] Optionally, the above methods can be combined in any way, and this application does not impose any restrictions.

[0092] In some embodiments, the visualization interface includes a main interface, which includes a first display area for displaying maternal-fetal overlap information, including the maternal-fetal overlap rate. When an abnormal maternal-fetal overlap rate is detected, the abnormal maternal-fetal overlap rate is flashed in the first display area; and the abnormal maternal-fetal overlap rate is also magnified in the first display area. For example, the magnified abnormal maternal-fetal overlap rate is flashed in the first display area according to a preset magnification ratio and flashing frequency. That is, the user can be informed of the abnormal maternal-fetal overlap rate by flashing the magnified abnormal maternal-fetal overlap rate, and a corresponding overlap alarm can be triggered.

[0093] In some embodiments, the visualization interface includes a main interface, which includes a first display area for displaying maternal-fetal overlap information. This maternal-fetal overlap information includes the maternal-fetal overlap rate and corresponding identification information. When an abnormal maternal-fetal overlap rate is detected, the abnormal maternal-fetal overlap rate is enlarged and displayed in the first display area. The corresponding identification information is also highlighted in the first display area. That is, the user is notified of the abnormal maternal-fetal overlap rate and an overlap alarm is triggered by enlarging the abnormal maternal-fetal overlap rate and highlighting its corresponding identification information.

[0094] See Figure 8 , Figure 8 This is a flowchart illustrating another embodiment of the maternal-fetal heart rate overlap detection method provided in this application. The method includes:

[0095] Step 81: Generate maternal-fetal overlap rate based on the collected original maternal physiological signals and original fetal physiological signals.

[0096] Step 82: Display maternal-fetal overlap information on the visualization interface. The maternal-fetal overlap information includes at least the maternal-fetal overlap rate.

[0097] Step 83: If the maternal-fetal overlap rate is greater than the first preset value, compare the changing trends between the original maternal physiological signals and the original fetal physiological signals.

[0098] In some embodiments, the first preset value is an empirical value obtained during the test, which can be set according to actual needs. For example, if you want to minimize false alarms, you can set the first preset value to a value slightly higher than the empirical value. If you want to avoid missing abnormal situations of maternal-fetal overlap, you can set the first preset value to a value slightly lower than the empirical value. Optionally, the first preset value can be 0.55, 0.6, 0.65, 0.7, etc.

[0099] In some embodiments, when there are at least two fetuses, each fetus corresponds to a maternal-fetal overlap rate. Therefore, step 83 can be performed for the maternal-fetal overlap rate corresponding to each fetus.

[0100] Specifically, the trend of change is used to indicate the direction of change of the two signals: the original maternal physiological signal and the original fetal physiological signal. This includes various trends such as both signals becoming faster, both signals becoming slower, one signal becoming faster, and the other signal becoming slower.

[0101] Step 84: If the trend is consistent, determine that the maternal-fetal overlap rate is abnormal.

[0102] In some embodiments, because the mother and fetus are different individuals, the trends of change between the original maternal physiological signals and the original fetal physiological signals will normally be inconsistent. Therefore, when the trends of change between the original maternal physiological signals and the original fetal physiological signals are consistent, an abnormal maternal-fetal overlap rate is determined.

[0103] Specifically, when the maternal-fetal overlap rate is greater than the first preset value, there is a possibility of abnormal maternal-fetal overlap. In this case, the changing trends of the original maternal physiological signals and the original fetal physiological signals used to generate the maternal-fetal overlap rate can be further analyzed. If the changing trends are consistent, it can better indicate that the fetal heart rate and the maternal heart rate overlap.

[0104] Step 85: If the trends are inconsistent, determine that the maternal-fetal overlap rate is normal.

[0105] Specifically, even if the maternal-fetal overlap rate is greater than the first preset value, but the change trends of the original maternal physiological signal and the original fetal physiological signal are inconsistent, for example, the original maternal physiological signal becomes faster while the original fetal physiological signal becomes slower, it indicates that the fetal heart rate and the maternal heart rate have not overlapped. In this case, no overlap alarm information will be output, but the signal will continue to be collected for observation, thereby reducing the probability of false alarms and improving the accuracy of maternal-fetal overlap abnormality judgment.

[0106] Step 86: When an abnormal maternal-fetal overlap rate is detected, an overlap alarm message is displayed for the abnormal maternal-fetal overlap rate.

[0107] The scheme disclosed in this embodiment can generate maternal-fetal overlap rate based on the collected original maternal and fetal physiological signals. On the one hand, it can avoid the problem that when judging whether maternal-fetal signals overlap by using fetal and maternal heart rates, the heart rate calculation result cannot be obtained due to technical reasons, thus failing to make an accurate judgment on maternal-fetal overlap, thereby improving the accuracy of maternal-fetal overlap judgment. On the other hand, compared with judging whether maternal-fetal signals overlap by using fetal and maternal heart rates, the poor quality of the original signals is prone to miscalculation of heart rate, resulting in inaccurate heart rate values ​​and thus failing to obtain an accurate maternal-fetal overlap judgment result. This application obtains a more accurate maternal-fetal overlap judgment result by directly comparing and calculating the two original signals and comprehensively judging and calculating based on the various information reflected in the original signals.

[0108] Furthermore, the solution disclosed in this embodiment can calculate the specific maternal-fetal overlap rate and display it on a visual interface. In related technologies, the existence of maternal-fetal overlap can only be determined based on the mother's heart rate and the fetal heart rate. If overlap is found, an alarm is triggered, but the degree of overlap is not reflected. False alarms may occur when the maternal and fetal heart rates are close. To confirm whether the current alarm is a false alarm or a real alarm, medical staff need to manually compare the maternal and fetal heart rate data from a previous period to verify the actual occurrence of maternal-fetal overlap. The solution disclosed in this application clearly informs medical staff of the current maternal-fetal overlap rate. When a maternal-fetal overlap alarm occurs, the magnitude of the overlap rate determines whether to confirm whether the alarm is a false alarm or a real alarm. When the value is large (e.g., 0.8, 0.9, etc.), it can be directly confirmed that the degree of maternal-fetal overlap is very strong and it is unlikely to be a false alarm. This reduces the number or frequency of manual data comparisons by medical staff, thereby saving manpower, reducing their workload, and improving their efficiency.

[0109] Furthermore, when the maternal-fetal overlap rate is greater than the first preset value, there is a possibility of abnormal maternal-fetal overlap. In this case, the changing trends of the original maternal physiological signals and the original fetal physiological signals used to generate the maternal-fetal overlap rate can be further analyzed. If the changing trends are consistent, it can better indicate that the fetal heart rate and the maternal heart rate overlap, thereby reducing the probability of false alarms and improving the accuracy of judging maternal-fetal overlap abnormalities.

[0110] See Figure 9 , Figure 9 This is a flowchart illustrating an embodiment of the maternal-fetal heart rate overlap detection method provided in this application. The method includes:

[0111] Step 91: Perform homology analysis on the collected original maternal physiological signals and original fetal physiological signals to obtain multiple correlation scores.

[0112] In some embodiments, the physiological signals generated by the cardiac activity of the same individual are synchronous (homogeneous). Based on this characteristic, homology analysis can be performed on the original maternal physiological signals and the original fetal physiological signals to obtain multiple correlation scores. The correlation score represents the degree of correlation between the original maternal physiological signals and the original fetal physiological signals. For example, if the electrocardiogram (ECG) signal and heart sound signal generated by the cardiac activity of the same individual are synchronous, homology analysis can be performed on the acquired original maternal ECG signal and the original fetal heart sound signal to obtain the correlation score between the two signals. Exemplarily, during homology analysis, the positions of the QRS complex and the first heart sound in the ECG signal, the positions of the T wave and the second heart sound in the ECG signal, the width of the QRS complex in the ECG signal, and the duration of the first heart sound can be compared.

[0113] Since the original maternal and fetal physiological signals are collected over time, homology analysis can be performed on the original maternal and fetal physiological signals according to the time series to obtain multiple correlations. Optionally, the method for homology analysis in this application can be autocorrelation processing, cross-correlation calculation, correlation coefficient calculation, etc., and this application is not limited to any particular method.

[0114] In some embodiments, the mother's electrocardiogram (ECG) signal and the fetal heart sound signal are obtained by a signal acquisition device. The mother's ECG signal and the fetal heart sound signal are subjected to interference suppression and then homology analysis to determine whether the mother's ECG signal and the fetal heart sound signal originate from the same object, thereby determining whether there is a case of overlapping maternal and fetal signals.

[0115] Step 92: Generate maternal-fetal overlap rate based on multiple correlations.

[0116] As can be seen, this embodiment directly determines whether there is overlap between the fetal heart rate and the mother's heart rate by comparing the correlation between the two original signals: the original maternal physiological signal and the original fetal physiological signal. This can avoid the situation where overlap detection cannot be performed due to the lack of maternal or fetal heart rate values, thereby improving the effectiveness and accuracy of maternal-fetal overlap detection.

[0117] In some embodiments, see Figure 10 Step 92 can be the following process:

[0118] Step 101: Obtain all relevance values ​​within a preset time period from multiple relevance values.

[0119] Optionally, the preset time period can be set according to actual needs. The length of the preset time period can be selected within a pre-set numerical range (such as 10-50 seconds). For example, the preset time period can be set to 30 seconds, 40 seconds, etc.

[0120] Specifically, during monitoring, the waveforms of the original maternal and fetal physiological signals are compared in real time. A correlation score is generated every second, so multiple correlation scores can correspond within a preset time period. For example, there are 40 correlation scores within 40 seconds.

[0121] Step 102: Determine the target relevance from all relevance values; wherein the target relevance is greater than the second preset value.

[0122] Specifically, correlation includes high correlation and low correlation. A correlation greater than a second preset value is considered high correlation, which is the target correlation that needs to be determined. A correlation less than the second preset value is considered low correlation. The second preset value is obtained based on experimental experience, for example, 0.6.

[0123] Step 103: Generate maternal-fetal overlap rate based on the number of target relevance scores.

[0124] In some embodiments, the ratio between the number of target correlations and the number of all correlations is used as the maternal-fetal overlap rate. For example, if the number of all correlations is 40 and the number of target correlations is 20, the maternal-fetal overlap rate is 0.5.

[0125] In related technologies, for example, when determining whether maternal-fetal signals overlap by comparing fetal and maternal heart rates, poor quality of the original signals can easily lead to miscalculation of heart rates, resulting in inaccurate heart rate values ​​and consequently, inaccurate results in determining maternal-fetal overlap. In this embodiment, homology analysis is performed on the collected original maternal and fetal physiological signals to calculate the degree of maternal-fetal overlap, eliminating the need to calculate both maternal and fetal heart rates before making a judgment, as in related technologies. Therefore, compared to judging maternal-fetal signal overlap solely based on a single heart rate value, this application comprehensively judges whether maternal-fetal signal overlap exists based on multiple pieces of information reflected in the original signals (e.g., the position of the first heart sound in the QRS wave signal and heart sound signal, the position of the T wave and second heart sound in the ECG signal, the width of the QRS wave, and the duration of the first heart sound). This comprehensive judgment yields a more accurate result, reducing the probability of false alarms due to similar maternal and fetal heart rates. Furthermore, medical personnel can further reduce the burden of long-term data review based on the overlap rate parameter.

[0126] The contraction and relaxation of the heart generate heart sounds, and changes in the electrical potential of myocardial cells are also reflected in electrocardiogram (ECG) signals. The heart sounds and ECG signals generated by the heart activity of the same individual are synchronously consistent; the first heart sound marks the beginning of ventricular contraction, and the second heart sound marks the beginning of ventricular relaxation, corresponding to the QRS wave and T wave in the ECG signal, respectively. That is, the ECG and heart sound signals of the same individual correspond in characteristics, but the QRS wave, T wave, and heart sound signals of different individuals exhibit irregularities.

[0127] In some embodiments, in response to an adjustment command, a position adjustment prompt is output; wherein the adjustment command is generated when there is an abnormal maternal-fetal overlap rate and a preset condition is met, and the position adjustment prompt is used to instruct the user to adjust the current position of the signal acquisition device; the preset condition may refer to the situation where the original maternal physiological signal and / or the original fetal physiological signal is unreliable. For example, if the maternal-fetal overlap rate is greater than a first preset value and continues to exceed a preset duration, it can be determined that the original signal is unreliable.

[0128] Optionally, the original maternal physiological signals and the original fetal physiological signals can be acquired using different signal acquisition devices. Therefore, the position adjustment prompt is used to indicate the adjustment of the corresponding signal acquisition device. For example, if an abnormality is detected in the maternal-fetal overlap between the fetal heart rate and the maternal-fetal heart rate, and it has been confirmed that the signal acquired by the corresponding signal acquisition device for fetal heart rate is unreliable, a position adjustment prompt will be output to remind medical staff to reposition the signal acquisition device for fetal heart rate until the fetal heart rate signal for fetal heart rate is found.

[0129] Specifically, the location adjustment prompts can use graphic and / or voice prompts to instruct users to adjust the current location of the signal acquisition device.
