The alternative embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other implementation manners.

[0064] Firstly referring to Figure 1 The embodiment of the present application provides a display method 100 for a medical device, comprising the following steps:

[0065] In step S110, a first blood flow hemodynamic parameter of a patient is acquired from a first source, the first blood flow hemodynamic parameter at least comprising a blood flow hemodynamic parameter obtained by performing an imaging examination on the patient;

[0066] At step S120, a second hemodynamic related parameter different from the first hemodynamic related parameter is acquired from a second source;

[0067] At step S130, the first hemodynamic related parameter and the second hemodynamic related parameter are displayed in a first display area on a display interface of the medical device;

[0068] The first hemodynamic related parameter and the second hemodynamic related parameter are displayed in the first display area on the display interface of the medical device, including:

[0069] A physiological organ map is displayed on the first display area;

[0070] The first hemodynamic related parameter and / or the second hemodynamic related parameter are determined to correspond to an organ in the physiological organ map;

[0071] The first hemodynamic related parameter and / or the second hemodynamic related parameter are displayed in a preset display manner in a preset area of the first display area.

[0072] The display method 100 for the medical device according to the embodiments of the present application can be executed by the medical device, which can be implemented as a monitor, a central station, etc. The medical device acquires a first hemodynamic related parameter and a second hemodynamic related parameter of a patient from a first source and a second source respectively, and displays the first hemodynamic related parameter, the second hemodynamic related parameter and a physiological organ map on the same screen, so as to present the overall hemodynamic condition of the patient, and improve the efficiency and quality of the user in browsing the hemodynamic information.

[0073] The first hemodynamic related parameter of the patient acquired from the first source at step S110 mainly includes a hemodynamic related parameter obtained by performing an image examination on the patient, and specifically includes but is not limited to a hemodynamic related parameter obtained by performing an ultrasound examination on the patient. The first hemodynamic related parameter can also include a hemodynamic related parameter from a CT (computed tomography) image, an MRI (magnetic resonance imaging) image, a DR image, etc. Exemplarily, the first source includes a device for acquiring the first hemodynamic related parameter, such as an ultrasound device, an X-ray device, and other imaging devices; the first source can also be other information transfer devices or data management systems.

[0074] Exemplarily, the hemodynamic related parameters obtained by the ultrasound examination of the patient include at least one of the following: a cardiac quantitative index, a pulmonary quantitative index, a vascular quantitative index, a cardiac semi-quantitative index, a pulmonary semi-quantitative index, and a vascular semi-quantitative index. The cardiac quantitative index includes but is not limited to left ventricular volume, left ventricular ejection fraction, VTI (velocity time integral) / SV (stroke volume) / CO (cardiac output) / SVV (stroke volume variation) of left ventricular outflow tract, tricuspid annular plane systolic excursion, etc.; the pulmonary quantitative index includes but is not limited to B-line number, B-line interval, etc.; the vascular quantitative index includes but is not limited to IVC (inferior vena cava) inner diameter, IVC collapse rate, IVC expansion rate, renal blood flow RI (pulsatility index) / PI (resistance index), cerebral blood flow RI / PI, etc.; the cardiac semi-quantitative index includes but is not limited to left ventricular dilation, left ventricular normal, left ventricular too small, etc., the pulmonary semi-quantitative index includes but is not limited to a small amount of B-line, a larger amount of discrete B-line, a large amount of fused B-line, etc.; and the vascular semi-quantitative index includes but is not limited to IVC expansion, IVC normal, IVC collapse, etc.

[0075] The hemodynamic related parameters obtained by the image examination of the patient can be automatically calculated after the medical image is collected by the imaging device, or can be calculated after the medical image is manually measured by the operator operating the imaging device. The way of obtaining the first hemodynamic related parameter can include directly connecting the imaging device to obtain the parameter, or connecting the imaging device to the monitoring network, and then obtaining the parameter through the monitoring network.

[0076] In step S120, the second hemodynamic related parameter obtained from the second source mainly includes the vital sign parameter of the patient related to hemodynamics. Exemplarily, the second source includes a device for collecting the second hemodynamic related parameter, such as a monitor, a ventilator, etc.; the second source can also be other information transfer device or data management system.

[0077] Exemplarily, the second hemodynamic related parameter includes at least one of the following: a monitoring parameter obtained by monitoring the patient, a ventilation parameter of the patient obtained by the ventilator, and a biochemical index of the patient. The second hemodynamic related parameter can be a continuous measurement value or a discrete measurement value.

[0078] Among them, the biochemical indicators of the patient are biochemical indicators closely related to the hemodynamic analysis, which are mainly from laboratory data. Exemplarily, the biochemical indicators of the patient include but are not limited to hemoglobin content (HGb) and lactic acid content (BLactic). The way to obtain the biochemical indicators can include directly accessing a third-party system storing the biochemical indicators through a network, such as a LIS (Laboratory Information System), or accessing the third-party system through the monitoring network by the information transfer device, and then forwarding the biochemical indicators to the medical device executing the method 100 after obtaining the biochemical indicators.

[0079] Due to the interaction between the heart and the lung, the ventilation parameters of the patient obtained by the ventilator also belong to the hemodynamic related parameters. The ventilation parameters of the patient obtained by the ventilator include but are not limited to the following: peak airway pressure (PIIP), plateau pressure (PLAT), positive end-expiratory pressure (PEEP), systolic pressure (ABPS), diastolic pressure (ABPD), and mean arterial pressure (ABPM). The way to obtain the ventilation parameters can include directly connecting the ventilator to obtain the ventilation parameters, or connecting the ventilator to the monitoring network, and then obtaining the ventilation parameters through the monitoring network.

[0080] Exemplarily, if the medical device is implemented as a monitor, the monitoring parameters obtained by monitoring the patient include directly collecting the monitoring parameters by the monitor, or extracting historical monitoring parameters from the memory of the monitor. The monitoring parameters obtained by monitoring the patient include but are not limited to the following: continuous cardiac output (CCI), heart rate (HR), stroke volume index (SVI), stroke volume variation (SVV), global end-diastolic index (GEDI), global ejection fraction (GEF), blood oxygen saturation (SpO2), oxygen delivery (DO2I), oxygen consumption (VO2I), extravascular lung water index (ELWI), and pulmonary vascular permeability index (PVPI), central venous pressure (CVP), and central venous oxygen saturation (ScVO2).

[0081] In step S130, the first hemodynamic parameter and the second hemodynamic parameter are displayed in a first display region on a display interface of the medical device; specifically, a physiological organ diagram is displayed on the first display region, the organ corresponding to the first hemodynamic parameter and / or the second hemodynamic parameter in the physiological organ diagram is determined, and the first hemodynamic parameter and / or the second hemodynamic parameter is displayed in a preset display manner in a preset region of the first display region. The first hemodynamic parameter and / or the second hemodynamic parameter can be displayed near the organ corresponding to the physiological organ diagram or be associated with the organ corresponding to the physiological organ diagram in other manners, for example, the first hemodynamic parameter and / or the second hemodynamic parameter is displayed in the same color as the organ in the physiological organ diagram or is connected to the organ by an indication line. The first display region is a display region specially used for displaying hemodynamic parameters, which can help to improve the efficiency and quality of reading these information by the user and make it easier for the user to master the overall blood flow of the patient by logically summarizing the hemodynamic parameters needed by the user through the physiological organ diagram.

[0082] An example of the first display region can be seen in Figure 2 In which the first unit 10 and the fourth unit 40 display hemodynamic parameters obtained by ultrasound examination of the patient; the second unit 20 displays biochemical indicators closely related to hemodynamic analysis, which are mainly from laboratory data; and the third unit 30 displays ventilation data from a ventilator. Figure 2 The other hemodynamic parameters shown are all from a monitor.

[0083] Exemplarily, in order to distinguish hemodynamic parameters from different sources, different marks are displayed on the first display region for hemodynamic parameters from different sources, in addition to hemodynamic parameters from the medical device itself. When the medical device is a monitor, the hemodynamic parameters from the medical device itself are monitoring parameters obtained by monitoring the patient, which can not be marked. For example, in Figure 2 In which the data from the laboratory data, the ultrasound device and the ventilator have different marks respectively, and the mark of each kind of data can visually indicate the data source, and the user can easily understand that the parameter without a mark is from the medical device itself.

[0084] It should be noted that hemodynamic parameters from different sources can also be marked without distinguishing between hemodynamic parameters from the medical device and hemodynamic parameters not from the medical device.

[0085] In addition, the blood flow related parameters can also be grouped without distinguishing the sources, and different blood flow related parameters in different groups can be displayed with different marks. The grouping manner is not specifically limited, and can be grouping according to organ categories or other manners.

[0086] In the first display area, the non-continuous parameters in the first blood flow related parameters and the second blood flow related parameters are displayed with marks indicating the measurement time of the non-continuous parameters. The non-continuous parameters specifically include parameters obtained based on user-specific measurement operations. For example, referring to Figure 2 , the non-continuous parameters include SVRI (peripheral vascular resistance index) displayed below the physiological organ diagram, and the non-continuous parameters are displayed with a symbol “*”, which indicates the measurement time of the non-continuous parameters. In the first display area, the “*” mark specifically corresponds to the measurement time (corresponding to the upper right corner mark * measurement time 2020-11-18 8:32:33 in Figure 2 ). The non-continuous parameters also include biochemical indicators and the like.

[0087] In one embodiment, continuing to refer to Figure 2 , after determining the organs corresponding to the first blood flow related parameters and / or the second blood flow related parameters in the physiological organ diagram, the first blood flow related parameters and / or the second blood flow related parameters can be displayed in a preset display manner near the corresponding organs in the physiological organ diagram.

[0088] Exemplarily, the preset display manner includes at least one of text, numerical value, graph, image and list. For example, quantitative indicators can be displayed in a numerical value display manner, and semi-quantitative indicators can be displayed in a text display manner; the graph can include a waveform graph, a trend graph and the like, and the image can include an ultrasound image, a CT image and the like; the list includes but is not limited to a list of multiple parameters of the same source, a list of multiple parameters of different sources, a list of the same parameter at different time points and the like.

[0089] The physiological organ diagram is a diagram showing the physiological structure of a human body or other animal body, and one or more tissue organs are displayed in the physiological organ diagram. Since the first display area of the embodiment of the present application is used to display blood flow related parameters, the physiological organ diagram displayed in the first display area at least includes a heart diagram, a lung diagram and a blood vessel diagram.

[0090] Exemplarily, the corresponding organ of the hemodynamic related parameter obtained by the image examination of the patient in the physiological organ map is determined according to the examination site thereof. Specifically, the examination site of the hemodynamic related parameter obtained by the image examination of the patient can be determined in various manners, so as to determine the corresponding organ of the hemodynamic related parameter obtained by the image examination of the patient in the physiological organ map according to the examination site. For example, the hemodynamic related parameter of the left ventricular site can be displayed near the left ventricle in the physiological organ map; the hemodynamic related parameter of the right ventricular site can be displayed near the left ventricle in the physiological organ map; the hemodynamic related parameter of the lung can be displayed near the lung in the physiological organ map, and so on.

[0091] Exemplarily, the determination of the examination site of the hemodynamic related parameter obtained by the image examination of the patient can include receiving the examination site labeled during the image examination, for example, receiving the examination site labeled when the hemodynamic related parameter is measured by the ultrasound device. The examination site labeled during the image examination can be the examination site manually labeled by the operator of the imaging device when the ultrasound image is collected; or can be the examination site automatically recognized and labeled by the imaging device based on the image information, wherein the method for recognizing the examination site can include a machine learning method such as SVM (Support Vector Machine) and decision tree, or a recognition method based on a deep learning network. The imaging device sends the examination site information to the medical device such as the monitor or the central station together with the hemodynamic related parameter, for determining the corresponding organ of the hemodynamic related parameter in the physiological organ map.

[0092] Alternatively, the examination site of the hemodynamic related parameter obtained by the image examination can be determined according to the recognition of the examination image obtained by the image examination of the patient. Specifically, the imaging device sends the hemodynamic related parameter and the examination image used for measuring the hemodynamic related parameter to the medical device, and the medical device recognizes the examination site of the hemodynamic related parameter according to the image information of the examination image, and the method for recognizing the examination site is similar to the method for recognizing the examination site by the imaging device.

[0093] Exemplarily, for the first hemodynamic parameter obtained by the ultrasound examination, the left ventricular volume, the left ventricular ejection fraction, the VTI (velocity time integral) / SV (stroke volume) / CO (cardiac output) / SVV (stroke volume variation) of the left ventricular outflow tract, the tricuspid annular displacement, and the tricuspid annular displacement correspond to the heart; the B-line number, the B-line interval, and other B-line related indexes correspond to the lung; the inferior vena cava diameter, the inferior vena cava collapse rate, the inferior vena cava expansion rate, the renal blood flow RI (pulsatility index) / PI (resistance index), the cerebral blood flow (pulsatility index) / PI (resistance index), and the like correspond to the blood vessels.

[0094] Determining the organ corresponding to the second blood flow dynamics related parameter in the physiological organ map can include determining the organ corresponding to the second blood flow dynamics related parameter in the physiological organ map according to the source of the second blood flow dynamics related parameter. For example, the ventilation parameters from the ventilator all correspond to the lung, including peak inspiratory pressure (PIIP), plateau pressure (PLAT), positive end-expiratory pressure (PEEP), systolic pressure (ABPS), diastolic pressure (ABPD), and mean arterial pressure (ABPM). The biochemical indicators of the patient all correspond to the blood vessels, including hemoglobin content (HGb) and lactic acid content (B Lactic).

[0095] Determining the organ corresponding to the second blood flow dynamics related parameter in the physiological organ map can also include determining the organ corresponding to the second blood flow dynamics related parameter in the physiological organ map according to the type of the second blood flow dynamics related parameter. For example, for monitoring parameters, extravascular lung water index (ELWI) and pulmonary vascular permeability index (PVPI) correspond to the lung; central venous pressure (CVP), central venous oxygen saturation (ScVO2), blood oxygen saturation (SpO2), oxygen delivery (DO2I), and oxygen consumption (VO2I) correspond to the blood vessels; continuous cardiac output (CCI), heart rate (HR), stroke volume index (SVI), stroke volume variation (SVV), global end-diastolic index (GEDI), and global ejection fraction (GEF) correspond to the heart.

[0096] In other embodiments, the positions of some blood flow dynamics related parameters relative to the physiological organ map can also be independent of the examination site, for example, the display positions of the blood flow dynamics related parameters can be customized by the user, or the display positions of the blood flow dynamics related parameters can be assigned according to the data source.

[0097] In some embodiments, an examination image obtained by examining at least one site of the patient can also be obtained from the first source, and the examination image is displayed in the first display area. The examination image includes one or more of an ultrasound image, a CT image, an MRI image, and an X-ray film. Since the first display area is mainly used to display blood flow dynamics related parameters, the examination image can be an examination image of a site related to blood flow dynamics, specifically, the site related to blood flow dynamics includes the heart and the lung. The examination image can include an examination image used to obtain the first blood flow dynamics related parameter, but is not limited thereto. The examination image can be a newly acquired examination image, or a examination image at a specified time.

[0098] In order not to affect the original layout of the display interface, the examination image can be displayed in an expanded window. When a command to display the examination image is received, the expanded window is popped up, and the examination image is displayed in the expanded window. The expanded window can be displayed superimposed on the first display area, and the user can move it outside the first display area to avoid blocking the first display area.

[0099] The first display interface can be used to display the current real-time hemodynamic related parameters, and can also display historical hemodynamic related parameters, so as to facilitate the user to review the historical hemodynamic related parameters. Specifically, a review operation instruction for the first display area is received, and historical hemodynamic related parameters of the patient are displayed in the first display area, wherein the historical hemodynamic related parameters can include the first hemodynamic related parameters, and can also include historical hemodynamic related parameters corresponding to the second hemodynamic related parameters. In some embodiments, the data type and display position of the historical hemodynamic related parameters are consistent with the real-time hemodynamic related parameters, and the only difference is the data collection time.

[0100] The review operation instruction for the first display area can include a selection instruction for a target time, and the historical hemodynamic related parameters include historical hemodynamic related parameters associated with the target time. The selection instruction for the target time can include a selection instruction for a target time point, or a selection instruction for a target time period, that is, the user can select to view the historical hemodynamic related parameters at a certain time point, or can view the historical hemodynamic related parameters in a certain time period. The target time period can be a fixed time period, for example, 2 minutes; or the target time period can also be a user-defined time period span.

[0101] Referring to Figure 2 , Figure 3 The fifth unit 50 is a time setting unit, which provides options for different times when a selection instruction for the fifth unit 50 is received, Figure 2 The selected option in the above is "current"

[0102] (Current), therefore Figure 2 The real-time hemodynamic related parameters are displayed; Figure 3 The selected option in the above is 11-17, 8:30, therefore Figure 3 The historical hemodynamic related parameters at 8:30 on November 17 are displayed.

[0103] In a similar way as displaying real-time hemodynamic related parameters, when displaying historical hemodynamic related parameters, the physiological organ map is displayed in the first display area, and the historical hemodynamic related parameters are displayed near the corresponding position of the physiological organ map. Optionally, if the historical hemodynamic related parameters viewed are historical hemodynamic related parameters in a period of time, not only the historical hemodynamic related parameters are refreshed with time, but also the changes of the historical hemodynamic related parameters can be more intuitively presented through the changes of the physiological organ map. For example, the speed of heart rate can be presented through the speed of the contraction of the heart graphic in the physiological organ map, the peripheral vascular resistance can be presented through the thickness of the expansion or compression of the blood vessel graphic in the physiological organ map, and the change of the left ventricular volume can be presented through the size change of the heart chamber graphic in the physiological organ map, etc.

[0104] In some embodiments, the review operation instruction on the first display area can further include a selection instruction on a target event, and the historical hemodynamic related parameters include historical hemodynamic related parameters associated with the target event. Continuing to refer to Figure 3 The fifth unit 50 can also be implemented as an event setting unit, which provides options of different events when receiving a selection instruction on the fifth unit 50, including an ultrasound event (Ultra), a biochemical analysis event related to arterial blood (Arterial Blood), an infusion event related to dobutamine (Bobutamine), etc. When receiving a selection instruction on a target event, the historical hemodynamic related parameters in the time period of the occurrence of the target event are displayed.

[0105] Further, referring to Figure 3 When receiving a selection instruction on a target event, a first time axis 60 including the duration of the target event can also be displayed in the first display area, and the first display area displays the historical hemodynamic related parameters corresponding to the selected time when a selection instruction on any time of the first time axis is executed. The first time axis allows the operator to pause and drag the play position like playing a video, so as to view the historical hemodynamic related parameters at any time in the target time period. In the process of displaying the historical hemodynamic related parameters, the changes of the physiological organ map present the changes of the historical hemodynamic related parameters.

[0106] The way of playing back historical hemodynamic related parameters based on events or user-defined time periods as described above can also be combined with the review of parameter change trends. For example, an event indication map in a preset time range can be displayed in a second display area of the display interface of the medical device, and the event indication map includes at least one event marker; when receiving a selection instruction on the at least one event marker, the first display area is displayed, and the historical hemodynamic related parameters associated with the selected event marker are displayed in the first display area.

[0107] The first display area and the second display area can be two display areas on the display interface that can be switched to display, that is, when a selection instruction for an event marker in the second display area is received, the second display area is switched to the first display area. Alternatively, the first display area and the second display area can also be two display areas on the display interface that can be displayed on the same screen, that is, when a selection instruction for an event marker in the second display area is received, the second display area and the first display area are simultaneously displayed on the display interface.

[0108] Referring to Figure 4 , the second display area can be used to review the trend of changes in historical hemodynamic parameters. Specifically, a second time axis 70 within a preset time range is displayed in the second display area, and a trend graph of at least one historical hemodynamic parameter of the patient within the preset time range is displayed in the second display area, the trend graph and the second time axis being aligned in the time dimension. When an operation instruction at any time on the second time axis is received, a baseline 90 is displayed at the position of the selected time, and the value of the intersection point of each trend graph and the baseline 90 is the value of the historical hemodynamic parameter involved in the corresponding trend graph at the selected time. When the baseline 90 is displayed, the value of the intersection point of each trend graph and the baseline 90 can also be displayed. In one embodiment, when an operation instruction at any time on the second time axis is received, the first display area can also be directly displayed, and the hemodynamic parameter at the selected time can be displayed in the first display area.

[0109] Further, at least one event marker is displayed on the second time axis 70, and the event marker is associated with at least one historical hemodynamic parameter. The time indication graph described above refers to the second time axis 70 with the event marker displayed. Each event marker corresponds to a preset icon, and the preset icon is displayed after the event marker is clicked, or the preset icon is always displayed in the second display area, and the preset icon is associated with the historical hemodynamic parameter associated with the event marker corresponding to the preset icon.

[0110] When the preset icon is displayed after the event marker is clicked, referring to Figure 4 , multiple event markers represented by short vertical lines are displayed on the second time axis, and a preset icon is displayed only below the selected event marker, and the preset icon displays the historical hemodynamic parameter associated with the selected event marker, Figure 4 , the selected event marker is a marker of a biochemical analysis event, and the historical hemodynamic parameter displayed in the preset icon is a biochemical index obtained by biochemical analysis.

[0111] Further, when the operation instruction for the preset icon is received, the first display area can be displayed, and the historical hemodynamic related parameters associated with the preset icon are displayed in the first display area. When the operation instruction for the preset icon is received, the historical hemodynamic related parameters before and after the event corresponding to the preset icon are displayed in the first display area.

[0112] In addition to displaying the first display area when the operation instruction for the preset icon is received, another implementation manner of switching from the second display area to the first display area includes displaying the icon 80 in the second display area, the icon 80 being an entrance of the first display area, and clicking the icon 80 to pop up a window containing the first display area.

[0113] In summary, the display method 100 for the medical device according to the embodiments of the present application can aggregate and display the hemodynamic related parameters from multiple sources, which can help to improve the efficiency and quality of the user browsing the hemodynamic related parameters, and make the user more easily master the hemodynamic condition of the patient.
