The present application will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings. In the following implementation manners, many details are described for better understanding of the present application. However, those skilled in the art can readily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the application are not shown or described in the description, this is to avoid the core part of the application being overwhelmed by too many descriptions, and for those skilled in the art, it is necessary to describe these operations in detail Relevant operations are not necessary, and they can fully understand the relevant operations according to the description in the specification and general technical knowledge in the field.

In addition, the characteristics, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be exchanged or adjusted in a manner obvious to those skilled in the art. Therefore, various sequences in the specification and drawings are only for clearly describing a certain embodiment, and do not mean a necessary sequence, unless otherwise stated that a certain sequence must be followed.

This application visually displays the patient's GEF and its changes in a graphical way. GEF (global ejectionfraction, global ejection fraction) refers to the percentage of the patient's stroke volume in the end-diastole volume of the ventricle. When the ventricle contracts, all the blood in the ventricle cannot be injected into the artery. Volume: The left ventricle is about 145ml, the right ventricle is about 137ml, and the stroke volume is 60-80ml. Considering the medical meaning of ejection fraction, when the end-diastolic volume of the ventricle is constant, the more blood the heart pumps out, the smaller the end-systolic volume of the heart, and the greater the value of the global ejection fraction; conversely, the heart The less blood pumped out, and the larger the end-systolic volume, the smaller the value of the global ejection fraction. Therefore, this application dynamically indicates the value of the global ejection fraction by displaying the volume of the left and right ventricles at the end-systole and changes, the larger/smaller the value of the user's ventricular ejection fraction parameter, the smaller/larger the value of the ventricular end-systolic volume. Therefore, the corresponding size of the ventricle can be displayed on the display device, thereby graphically displaying the patient's The physiological parameter of global ejection fraction, when the obtained patient GEF parameter value is too low, shows a large-sized systolic heart, when the obtained patient GEF parameter value is normal, it shows a normal-sized systolic heart, and when the obtained patient GEF parameter value is normal, it shows a normal-sized systolic heart. When the patient's GEF parameter value is too high, a small-sized systolic heart is displayed, so that the medical staff can visually observe the patient's GEF parameter value and changes. In some preferred embodiments, in order to allow the medical personnel to visually judge whether the patient's GEF parameter is too high or too low or in a normal state, a systolic heart with normal size can also be displayed as a comparison. Preferably, this is used as The contrasted systolic heart and the real-time display of the patient's systolic heart are displayed in the same area. For example, the contrasted heart and the real-time displayed patient's heart are overlapped, so that when the patient's heart completely overlaps with the contrasted heart area, the medical staff can directly judge the current situation. The patient's GEF is in the normal range. When the patient's heart is included in the contrasted heart area, it can be directly judged that the patient's GEF is too high at this time. When the patient's heart is completely included in the contrasted heart area, it can be directly judged that the patient's GEF GEF is too low.

Please refer to FIG. 1 , this embodiment provides a device for graphically displaying changes in ventricular ejection fraction, which includes an ejection fraction acquisition module 10 , a data processing module 30 and a display module 50 connected in sequence, which will be described in detail below.

The ejection fraction acquisition module 10 is used for real-time or regular acquisition of data signals representing the ventricular ejection fraction of the user or the patient. The ejection fraction is an important physiological parameter that can reflect the state of the patient's heart. For example, when the monitored ejection fraction is too low , indicating that the patient's cardiac insufficiency.

In a preferred embodiment, as shown in FIG. 2, the ejection fraction acquisition module 10 further includes a failure judgment module 10a, which is used for when the ejection fraction acquisition module 10 cannot acquire the data signal representing the user's ventricular ejection fraction or When the time to acquire the data signal representing the user's ventricular ejection fraction exceeds a preset invalidation time range, the data processing module 30 is provided with a graphic display data for generating a prompt to the user that the current ejection fraction measurement is abnormal.

The data processing module 30 is wired or wirelessly connected to the ejection fraction acquisition module 10. For example, in one embodiment, the data processing module 30 is wired to the ejection fraction acquisition module 10 through wires. In another embodiment, the data processing The module 30 is wirelessly connected with the ejection fraction acquisition module 10 through a wireless circuit. When the data processing module 30 is wirelessly connected with the ejection fraction acquisition module 10, the patient's GEF can be monitored remotely. The data processing module 30 is used to process the data signal output by the ejection fraction acquisition module 10 to generate graphic display data including the information of the ventricular end systolic volume, wherein the ejection fraction acquisition module 10 outputs the user's ventricular ejection fraction represented by the data signal The larger/smaller the value of , the smaller/larger the value of the ventricular end systolic volume included in the generated graphic display data.

The display module 50 is connected with the data processing module 30, and is used for graphically displaying the above-mentioned ventricular end-systolic volume information. In a specific embodiment, the manner of graphically displaying the above-mentioned ventricular end systolic volume information by the display module 50 includes at least one of graphics and a combination of graphics and colors and/or patterns. For example, on the display module 50, a three-dimensional view or a cross-sectional view or a contour view of the heart of a pseudo-object is displayed, and the size (such as area) of the heart of the pseudo-object displayed on the display module 50 is used to represent the above-mentioned ventricular end-systolic volume information, When the value of the user's ventricular ejection fraction represented by the acquired data signal is larger/smaller, and the value of the ventricular end systolic volume included in the generated graphic display data is smaller/larger, a more Heart image in small/large size. In a preferred embodiment, as shown in FIG. 3 , the simulated left ventricle 51 and right ventricle 52 can also be used to represent the patient's left ventricular ejection fraction and right ventricular ejection fraction, respectively. In order to distinguish the left ventricle 51 and the right ventricle 52 on the display module 50, different colors may also be attached to them, for example, the left ventricle 51 is displayed in blue, and the right ventricle 52 is displayed in red. In addition, when the failure judgment module 10a fails to obtain the data signal representing the user's ventricular ejection fraction due to the ejection fraction obtaining module 10 or the time for obtaining the data signal representing the user's ventricular ejection fraction exceeds a preset failure time range, the After the processing module 30 provides a graphic display data used to generate a reminder to the user that the current measurement of the ejection fraction is abnormal, the display module 50 receives the graphic display data that prompts the user that the current measurement of the ejection fraction is abnormal, and then graphically displays the end-stage ventricle in gray. Systolic volume information, such as a pseudo-heart or left ventricle 51 and right ventricle 52 are displayed in gray.

In order to enable the medical staff to quickly check the current GEF information of the patient, so as to quickly determine whether or how to perform the next step of intervention, in one embodiment, as shown in Figure 4, the graphical display of the changes in ventricular ejection fraction of the present application The apparatus may also include an initial state module 70 . The initial state module 70 is used to provide the data processing module 30 with a data signal characterizing the ventricular ejection fraction whose parameter value is in the normal range, so as to generate graphical display data including the information of the normal size of the ventricular end-systolic volume as a comparison. In one embodiment, the display module 50 may also use the pseudo-heart image or the pseudo-left and right ventricles to display the graphical display data including normal-sized ventricular end-systolic volume information.

In order to more intuitively judge whether the patient's GEF is too high or too low, in one embodiment, the display module 50 can display the patient's GEF and the GEF parameter as a comparison in real time in the same area respectively, for example, let The contrasted heart (of course, it can also be the left ventricle and the right ventricle) overlaps with the patient's heart displayed in real time, so that when the patient's heart completely overlaps with the contrasted heart area, the medical staff can directly judge that the patient's GEF is in the normal range at this time. When the patient's heart is included in the contrasted heart area, it can be directly judged that the patient's GEF is too high at this time, and when the patient's heart is completely included in the contrasted heart area, it can be directly judged that the patient's GEF is too low at this time. In order to distinguish the GEF parameters of the patient monitored in real time from the GEF parameters of the normal range, when the display module 50 displays the heart graph of the GEF parameters of the normal range as a comparison, it can be displayed using a dotted line, that is, the data processing module 30 generates the normal size. The outline of the graph of the ventricular end-systolic volume information is a dotted line, as shown in Figure 5, (a) in Figure 5 represents the end-systole of the left ventricle 51 and the right ventricle 52 when the value of the monitored GEF parameter is lower than the normal range Volume, it can be seen that the left and right ventricle of the patient displayed in real time in the figure is larger than the left and right ventricle of the GEF value of the normal range shown by the dotted line as a contrast; (b) in Figure 5 indicates that the value of the GEF parameter of the monitored disease is between For the end-systolic volumes of the left ventricle 51 and the right ventricle 52 in the normal range, it can be seen that the real-time display of the patient's left and right ventricle in the figure is equal to the size of the left and right ventricle shown by the dotted line that represents the normal range of the GEF value; FIG. 5 (c) indicates the end-systolic volumes of the left ventricle 51 and the right ventricle 52 when the value of the monitored GEF parameter of the disease is higher than the normal range. It can be seen that the left and right ventricle of the patient displayed in real time in the figure is smaller than that shown by the dotted line for comparison. Characterize the left and right ventricles with GEF values in the normal range. The initial state module 70 can be preset with the data signal of the ventricular ejection fraction whose characteristic parameter value is in the normal range when leaving the factory; and/or, it can also be connected to it through an input module (not shown in the figure), It is for the user to input a data signal representing the ventricular ejection fraction to the initial state module 70 according to his actual situation.

The device for graphically displaying changes in ventricular ejection fraction of the present application can be integrated into a monitoring system, for example, to be used together with other physiological parameters of the patient monitored in the monitoring system.

In a preferred embodiment, the ejection fraction obtaining step S10 also includes a failure judgment step S12, when the data signal representing the user's ventricular ejection fraction cannot be obtained or the time for obtaining the data signal representing the user's ventricular ejection fraction exceeds a preset When the failure time range is set, the output one is used to generate graphic display data for prompting the user that the current ejection fraction measurement is abnormal.

S30. Data processing step: process the above-mentioned data signal to generate graphic display data containing the information of ventricular end-systole volume, wherein the larger/smaller the value of the user's ventricular ejection fraction represented by the above-mentioned data signal, the generated said graphic display Data contain smaller/larger values of ventricular end systolic volume.

S50. Displaying step: displaying the ventricular end-systolic volume information in a graphical manner.

In a specific embodiment, the manner of graphically displaying the ventricular end systolic volume information in the display step S50 includes at least one of graphics and a combination of graphics and colors and/or patterns. For example, display a three-dimensional view or cross-sectional view of a simulated heart, and use the size (such as area) of the simulated heart to represent the above-mentioned ventricular end-systolic volume information, when the obtained data signal represents the value of the user's ventricular ejection fraction Larger/smaller, the smaller/larger the value of the ventricular end-systolic volume included in the above-mentioned graphic display data generated, a smaller/larger size heart image is displayed at this time. In a preferred embodiment, please refer back to FIG. 3 , the pseudo left ventricle 51 and right ventricle 52 can also be used to represent the patient's left ventricular ejection fraction and right ventricular ejection fraction, respectively. In order to distinguish the left ventricle 51 and the right ventricle 52 on the display screen, different colors can also be attached to them, for example, the left ventricle is displayed in blue, and the right ventricle is displayed in red. In addition, when the failure judgment step S12 is because the ejection fraction acquisition module 10 cannot acquire the data signal representing the user's ventricular ejection fraction or the time for obtaining the data signal representing the user's ventricular ejection fraction exceeds a preset failure time range, a After generating the graphic display data for prompting the user that the current ejection fraction measurement is abnormal, the display step S50, after receiving the graphic display data for prompting the user for the current abnormal ejection fraction measurement, graphically display the ventricular end-systolic volume information in gray, For example, a pseudo-heart or a left ventricle 51 and a right ventricle 52 are shown in gray.

In one embodiment, the above-mentioned graphical display data as a comparison enables the display step S50 to also use the simulated heart image or the simulated left ventricle and right ventricle to display the graphical display data including the normal-sized ventricular end-systolic volume information . In order to more intuitively judge whether the patient's GEF is too high or too low, in one embodiment, the above-mentioned graphic display data as a comparison enables the display step S50 to display the patient's GEF and the patient's GEF in real time in the same area respectively in the same area. The contrasted GEF parameters, for example, let the contrasted heart (of course, it can also be the left ventricle and the right ventricle) overlap with the patient's heart displayed in real time, so that when the patient's heart and the contrasted heart area completely overlap, the medical staff can directly judge the time The patient's GEF is in the normal range. When the patient's heart is included in the contrasted heart area, it can be directly judged that the patient's GEF is too high at this time. When the patient's heart is completely included in the contrasted heart area, it can be directly judged that the patient's GEF GEF is too low. In order to distinguish the GEF parameters of the patient monitored in real time from the GEF parameters of the normal range, the above-mentioned graphic display data as a comparison makes the display step S50 display the heart graphic of the GEF parameters as a comparison of the normal range, using dotted lines to display, that is, in the data The outline of the graph containing the normal-sized ventricular end-systolic volume information generated in processing step S30 is a dotted line, please refer back to FIG. 5 , and details will not be repeated here. In the initial state step S70 , the data signal used to provide the ventricular ejection fraction with a characteristic parameter value in the normal range can be set by preset or input by the user.

The device, method and monitoring system for graphically displaying changes in ventricular ejection fraction of the present application can characterize the acquired patient's GEF parameter value through the size of the simulated left ventricle and right ventricle graph. At the same time, in some implementations In the example, the graph of left ventricle and right ventricle of normal GEF parameter values is also displayed, so that medical staff can quickly check the information of the patient's current GEF parameters, and quickly judge whether or how to carry out the next step of intervention. Of course, in addition to visually displaying the GEF parameter value of the patient with graphical display, the present application can also simultaneously display other parameters related to the patient's physiological state in the form of numerical values or waveforms. Since the GEF parameter information of the patient is displayed graphically, Other physiological parameters displayed as numerical values or waveforms will not interfere with the observation of GEF parameter information by medical staff.
