[0003] The monitor can measure the patient's physiological parameters and display the measured values.

[0032] Current monitors can display the measured values ​​of some physiological parameters of patients. The display method is relatively simple, just the numerical value of the measured value, or the trend graph and / or waveform graph corresponding to the physiological parameter. Medical staff can only subjectively judge whether the current measured value falls within the expected target range, and whether it falls within the target range most of the time (the treatment target range is often not equal to the alarm range, and in the past there was no explicit indication of whether the measured value is within the target range). The display of whether the current measured value falls within the expected target range is not very intuitive, and cannot intuitively provide medical staff with corresponding diagnosis and treatment reference information, and cannot well meet the monitoring needs of medical staff.

[0033] The present application provides a method for displaying physiological sign parameters, which can improve the richness of the displayed parameter content and help medical staff understand the current physiological state of the monitored object.

[0034] See Figure 1 , which shows a process of a method for displaying physiological sign parameters.

[0035] like Figure 1 As shown, the process may specifically include steps 1.1-1.4.

[0036] Step 1.1: Obtain measurements of physiological parameters.

[0037] Specifically, a measurement value of at least one physiological sign parameter of the monitored object is obtained, and the measurement value of the physiological sign parameter is obtained from the monitored object through at least one sensor. The physiological sign parameter can be a parameter of any physiological sign of the monitored object, such as heart rate, pulse rate, blood oxygen saturation, respiratory rate, etc.

[0038] The measured values ​​of the physiological sign parameters collected by the sensor can be sent to the storage module of the monitoring system for storage, and these basic data can be used as the basic data for display analysis. In other words, the measured values ​​of the physiological sign parameters can be the sensor storing the measured values ​​of the physiological sign parameters in the storage module of the monitoring system, and the present application then obtains them from the storage module. Of course, the measured values ​​of the physiological sign parameters can also be obtained directly from the sensor.

[0039] Therefore, the physiological sign parameter display method provided by the present application can be applied not only to bedside devices but also to central stations. When applied to bedside devices, the physiological sign parameters are obtained through various physiological parameter accessory devices; when applied to central stations, the central stations obtain the physiological sign parameter data from bedside devices through the network.

[0040] Step 1.2: Provide a monitoring interface.

[0041] Specifically, the monitoring interface includes a status indication area, which displays at least one graphical status indicator. The graphical status indicator includes multiple indicator blocks, which respectively correspond to multiple parameter value intervals of physiological sign parameters, and the multiple indicator blocks are arranged in order according to the numerical values ​​of the physiological sign parameters and displayed in the status indication area.

[0042] The status indication area in the monitoring interface can be an area embedded in the monitoring interface, or it can be a window area suspended on the monitoring interface. The position attributes, shape attributes, display attributes, status attributes, etc. of the status indication area can be adjusted. For example, the position attribute of the status indication area refers to the display position of the status indication area in the monitoring interface; the shape attribute of the status indication area includes the style and size of the shape, for example, the shape can be various, such as rectangle, circle, heart shape, etc.; the display attribute of the status indication area refers to the color, brightness, contrast and other attribute information of all or part of the area; the status attributes of the status indication area include display or non-display attributes, embedding in the monitoring interface or floating in the monitoring interface, etc.

[0043] The monitoring interface includes a graphic composed of multiple indicator blocks. Different indicator blocks correspond to different parameter value intervals of physiological sign parameters. Different parameter value intervals can represent different physiological states of the monitored object. It can be seen that the graphic has an intuitive indication function for the physiological state. For the convenience of description, the graphic can be called a graphical state indicator. The indicator blocks are arranged in order according to the numerical values ​​of the physiological sign parameters, such as from left to right or from top to bottom, and the parameter values ​​of the physiological sign parameters gradually increase.

[0044] It should be noted that the number of graphical status indicators is not limited to one, but may be multiple. In the case where there are multiple graphical status indicators, different graphical status indicators correspond to different physiological sign parameters.

[0045] See Figure 2-4 , which shows the graphical status indicators corresponding to blood oxygen saturation, pulse rate and perfusion index respectively.

[0046] like Figure 2 As shown, the graphical status indicator of blood oxygen saturation (SpO2) includes four indicator blocks. Among them, indicator block 201 corresponds to the parameter value interval of blood oxygen saturation value 0-80%, which is used to indicate a high severity state; indicator block 202 corresponds to the parameter value interval of blood oxygen saturation value 80%-90%, which is used to indicate a medium severity state; indicator block 203 corresponds to the parameter value interval of blood oxygen saturation value 90%-95%, which is used to indicate the target state of blood oxygen treatment; indicator block 204 corresponds to the parameter value interval of blood oxygen saturation value 95%-100%, which is used to indicate a normal blood oxygen state. Of course, four indicator blocks are described above. In fact, each indicator block can be further subdivided into multiple sub-indicator blocks.

[0047] like Figure 3As shown, the graphical status indicator of pulse rate (PR) includes three indicator blocks. Among them, indicator block 301 corresponds to the parameter value interval of pulse rate value 0-100, which can indicate the state of low pulse rate; indicator block 302 corresponds to the parameter value interval of pulse rate value 100-200, which can indicate the physiological alarm range of pulse rate; indicator block 303 corresponds to the parameter value interval of pulse rate value greater than 200, which can indicate the state of too fast pulse rate. The unit of pulse rate value is beats per minute (bpm for short). Of course, three indicator blocks are described above. In fact, each indicator block can be further subdivided into multiple sub-indicator blocks.

[0048] like Figure 4 As shown, the graphical status indicator of the perfusion index (PI) includes three indicator blocks. Among them, indicator block 401 corresponds to the parameter value interval of the perfusion index value of 0-0.3, which can indicate that the patient is in a serious state of weak perfusion, and because the weak perfusion is too low, the blood oxygen measurement value may not be accurate at this time; indicator block 402 corresponds to the parameter value interval of the perfusion index value of 0.3-1, which can indicate that the current patient has a weak perfusion problem, and indicator block 403 corresponds to the parameter value interval of the perfusion index value greater than 1, which can indicate that the current patient has a good perfusion condition. Of course, three indicator blocks are described above. In fact, each indicator block can be further subdivided into multiple sub-indicator blocks.

[0049] It should be noted that for different physiological sign parameters, the parameter value interval range corresponding to the indicator block is different, which can be set according to the clinical guidance significance. In addition, in order to help medical staff understand the partition range of each parameter value in the graphical status indicator, such as Figure 2-4 As shown, the graphical status indicator may include critical values ​​of parameter value partitions.

[0050] In the case of multiple physiological sign parameters, graphical status indicators of multiple physiological sign parameters can be displayed on the monitoring interface at the same time. Figure 5 As shown, the monitoring interface includes graphical status indicators of three physiological sign parameters: blood oxygen saturation SpO2, pulse rate PR, and perfusion index PI.

[0051] Step 1.3: Determine the parameter value interval to which the measured value of the physiological sign parameter belongs.

[0052] Specifically, monitoring of the target object can generate monitoring data, and the monitoring data includes the measured value of the physiological sign parameter. The graphical status indicator of the physiological sign parameter includes multiple parameter value intervals, and the parameter value interval to which the measured value belongs is determined according to the size of the measured value of the physiological sign parameter. The measured value of the physiological sign parameter can specifically be the currently measured parameter value, that is, the real-time measurement value.

[0053] For example, the physiological sign parameter is blood oxygen saturation, and Figure 2 The graphical status indicator of blood oxygen saturation shown in the figure includes four parameter value intervals. Assuming that the measured value of the blood oxygen saturation of a monitored object is 93%, according to Figure 2 It can be seen from the four parameter value intervals that the parameter value interval to which the measured value belongs is the parameter value interval corresponding to 90%-95%.

[0054] Step 1.4: Display output in the indicator block corresponding to the parameter value interval to which the graphical status indicator and the measured value belong.

[0055] The graphical status indicator includes multiple indicator blocks, and different indicator blocks correspond to different parameter value intervals. After determining the parameter value interval to which the measured value belongs, the indicator block corresponding to the parameter value interval is prompted. Different display styles are used to distinguish the multiple indicator blocks of the graphical status indicator. The display method may include color distinction, highlighting, adding indicator marks, etc. The specific prompt method is described in detail below in conjunction with the diagram, and is not repeated here. Of course, the display method can also be other, as long as it can be distinguished from other parameter value partitions.

[0056] Different parameter value intervals represent different physiological states. The parameter value interval to which the measured value belongs can remind medical staff what the physiological state of the monitored object is at the time when the measured value is collected. Figure 2 For example, the parameter value interval ranging from 90% to 95% in the graphical status indicator represents the target state of blood oxygen treatment. If the parameter value interval to which the measured value belongs is this interval, it means that the physiological state of the monitored object has reached the state that the treatment target wants to achieve.

[0057] As can be seen from the above technical solutions, the present application provides a method for displaying physiological sign parameters, which can provide a graphical status indicator of physiological sign parameters in a monitoring interface, wherein the graphical status indicator includes a plurality of indicator blocks, and parameter value partitions corresponding to different indicator blocks correspond to different physiological states, obtain the measured value of the physiological sign parameter of the monitored object, determine the parameter value interval to which the measured value belongs, and prompt the indicator block corresponding to the parameter value interval in the graphical status indicator. In this way, medical staff can understand the current physiological state of the monitored object by observing the prompted indicator blocks.

[0058] With the development of refined monitoring, the clinical evaluation of measurement values ​​is no longer limited to a single state of whether the measurement value exceeds the alarm threshold. Medical staff hope to be able to perform more state classifications on the measurement values. The graphical status indicator provided by this application contains multiple parameter value intervals. Different parameter value intervals correspond to different physiological states. By observing the graphical status indicator, medical staff can perform refined monitoring of a variety of different physiological states of the monitored object.

[0059] The following specifically describes how to indicate the indicator block corresponding to the measured value in the graphical status indicator.

[0060] In one embodiment, the plurality of indicator blocks of the graphical status indicator have an initial brightness value and a preset brightness value. The initial brightness value indicates the brightness value when the measured value does not correspond to the indicator block; the preset brightness value indicates the brightness value when the measured value corresponds to the indicator block.

[0061] Therefore, in order to prompt the indicator block corresponding to the measured value, the display brightness of the indicator block corresponding to the parameter value interval to which the measured value belongs can be increased from the initial brightness value to the preset brightness value in the graphical status indicator. In order to achieve the best prompt effect, the initial brightness value is low brightness and the preset brightness value is high brightness. In other words, the indicator block corresponding to the parameter value interval to which the measured value belongs is highlighted.

[0062] The initial brightness values ​​and preset brightness values ​​of the multiple indicator blocks may be the same, and after the indicator block corresponding to the measured value is determined, only the indicator block corresponding to the measured value is converted for brightness display. At the same time, the initial brightness values ​​and preset brightness values ​​of the multiple indicator blocks may also be different.

[0063] In one embodiment, the plurality of indicator blocks of the graphical status indicator have an initial color and a preset color. The initial color indicates the color when the measured value does not correspond to the indicator block; the preset color indicates the color when the measured value corresponds to the indicator block.

[0064] Therefore, in order to indicate the indicator block corresponding to the measured value, the display color of the indicator block corresponding to the parameter value interval to which the measured value belongs can be increased from the initial color to the preset color in the graphical status indicator. In order to achieve the best prompting effect, the initial color is light and the preset color is dark. In other words, the indicator block corresponding to the parameter value interval to which the measured value belongs is displayed in a darker color.

[0065] The initial colors and preset colors of the multiple indicator blocks may be the same, and after the indicator block corresponding to the measured value is determined, only the indicator block corresponding to the measured value is displayed in a darker color. At the same time, the initial colors and preset colors of the multiple indicator blocks may also be different.

[0066] In some embodiments, it may be a combination of the above two embodiments.

[0067] In one embodiment, the multiple indicator blocks of the graphical status indicator include a target indicator block, and the target indicator block is used to indicate the expected state of the physiological sign parameter. Therefore, if the parameter value interval to which the measured value belongs is the parameter value interval corresponding to the target indicator block, the target indicator block is displayed and output in a display output manner different from that of other indicator blocks.

[0068] The expected state of the physiological sign parameter may include any of the following states, such as a normal state, an abnormal state, and a treatment target state. The target indication block refers to an indication block that indicates a certain expected state among multiple indication blocks. If the measured value happens to correspond to the target indication block, the display output mode of the target prompt block can be distinguished from the display output modes of other indication blocks.

[0069] There may be many ways to distinguish. For example, if the display output mode of the indicator block is to adjust the display brightness, the way to distinguish may be that the display brightness adjustment value of the target prompt block is larger or smaller. For another example, if the display output mode of the indicator block is to switch the display color, the way to distinguish may be that the display color of the target prompt block after switching is different from the display color of other prompt blocks after switching. For another example, the shape of the target indicator block is an ellipse, and the shape of the non-target indicator block is a rectangle. For another example, the target indicator block is displayed with a shading fill, and the non-target indicator block is displayed without a shading fill. For another example, it may be a combination of the above methods or other ways of distinguishing.

[0070] The following describes the display output method by taking the expected state as the treatment target state as an example.

[0071] The treatment target state indicates the state that the monitored object needs to reach after the treatment in the monitoring scenario. This state can be the expected treatment state for all monitored objects generally recognized in the medical field, or it can be the expected treatment state set for a specific monitored object that the specific monitored object needs to achieve in a specific monitoring scenario.

[0072] The parameter value interval corresponding to the treatment target state can be called the parameter value interval of the treatment target value, that is, the parameter values ​​belonging to the parameter value interval are all treatment target values. Moreover, among the multiple indication blocks, the indication block corresponding to the parameter value interval of the treatment target value can be called the treatment target indication block.

[0073] In order to prompt the treatment target indication block, a prompt can be added to the corresponding position of the treatment target indication block in the graphical status indicator. The prompt can be in text form, such as the above Figure 2 , 5 , and the following Figures 6A-6FThe “target” in the text (or the English name of the target “target”). Alternatively, the prompt may be a picture or a symbol, such as a picture or a symbol of a smiling face. Alternatively, the prompt may be in other forms.

[0074] When it is determined that the measured value of the physiological sign parameter jumps from the parameter value interval belonging to the non-treatment target value to the parameter value interval belonging to the treatment target value, a preset display style different from the original display style is used for display output in the treatment target indication block.

[0075] The original display style indicates the display style when the measured value does not correspond to the treatment target indication block; the preset display style indicates the display style when the measured value corresponds to the treatment target indication block. If the measured value jumps from the parameter value interval to which the non-treatment target value belongs to the parameter value interval to which the treatment target value belongs, it means that the measured value jumps from a state not corresponding to the treatment target indication block to a state corresponding to the treatment target indication block, and the display style needs to jump from the original display style to the preset display style.

[0076] Of course, if the measured value jumps to the opposite situation, that is, it jumps from the parameter value interval belonging to the treatment target value to the parameter value interval belonging to the non-treatment target value, the display style can be jumped in the opposite direction, that is, the preset display style is canceled, and the original display style is used for display output in the treatment target indication block.

[0077] The display style may include brightness value and / or display color. For specific transition methods, please refer to the first two embodiments of this section.

[0078] In one embodiment, in order to prompt the indicator block corresponding to the parameter value interval to which the measured value belongs, an indicator icon may be displayed at the position of the indicator block corresponding to the parameter value interval to which the measured value belongs. The indicator icon points to the indicator block corresponding to the parameter value interval to which the measured value belongs.

[0079] The indicator icon can be a cursor pointer, such as Figure 2-6F The location where the indicator icon is added needs to be able to prompt the medical staff, that is, to prompt the medical staff which indicator block the measured value corresponds to. For example, when the graphical status indicator is a horizontal straight bar structure, the indicator icon is added directly above or below the indicator block; for another example, when the graphical status indicator is an arc structure, the indicator icon is added in the center of the arc of the indicator block. And so on.

[0080] It should be noted that the above embodiments can be combined arbitrarily. For example, after determining the indicator block corresponding to the measurement value, the preset color of the indicator block is highlighted, and an indicator icon is added at the corresponding position of the indicator block.

[0081] Furthermore, in order to enable the monitoring personnel to understand the physiological state of the monitored object, the measured value may be displayed in the status indication area of ​​the monitoring interface, and / or the waveform and / or trend graph corresponding to the physiological sign parameter may be displayed in the status indication area of ​​the monitoring interface. For example, for blood oxygen measurement, a tracing wave (waveform graph) about blood oxygen may be displayed in the status indication area, or a blood oxygen saturation trend graph (a graph depicting the blood oxygen saturation values ​​obtained by continuous measurement over a period of time) may be displayed.

[0082] The font and size of the measured value can be preset and can also be modified. In order to provide a prominent prompt, the font can be relatively large, that is, a large font display mode is used.

[0083] The display position of the measured value can be arbitrary or set according to the position of the graphical status indicator. The relative position of the graphical status indicator and the measured value can be up and down, left and right, etc. The graphical status indicator can be above the measured value, or the two positions are opposite; the graphical status indicator can be to the left of the measured value, or the two positions are opposite.

[0084] See below Figure 6D-6F In the monitoring interface shown, the current measured value of blood oxygen saturation, 93%, is located below, on the left and on the right of the graphical status indicator.

[0085] Physiological sign parameters may have alarm thresholds. If the measured value exceeds the alarm threshold, the measured value may be displayed in a preset alarm prompt mode to remind medical staff that the target physiological sign parameter of the monitored object is abnormal. The preset alarm prompt mode may include any one or more of inverted color display, changing from a non-alarm color to an alarm color such as red, adding a background texture, and flashing. Figure 4 and 5 As shown in the figure, if the measured value of the perfusion index exceeds the alarm threshold of 0.5, the value is inverted from black to white, and a grayscale background is added. Of course, the alarm prompt method can also be other, not limited to this. It should be noted that the alarm threshold can include multiple alarm thresholds, and different alarm thresholds correspond to different inverted colors. When the alarm threshold is exceeded, the inverted color needs to be the corresponding color. For example, the inverted color of the high-level alarm threshold is red, and the inverted color of the medium-level alarm threshold is yellow.

[0086] The graphical status indicator is formed by connecting multiple indicator blocks. Regardless of whether the indicator blocks are of the same shape or different shapes, and whether the shapes are regular or irregular, the connection method of the multiple indicator blocks will form a connecting line, and the shape of the connecting line will determine the overall shape of the graphical status indicator. For example, Figure 3-5 In the graphical status indicator, the connection lines of the multiple indicator blocks are arc lines, so the overall structure of the graphical status indicator is an arc.

[0087] Of course, the shape of the graphical status indicator is not limited to an arc, and may also be other shapes. Figures 6A-6C , which is Figure 2 Other implementations of the graphical status indicator shown in FIG. Fig. 6A As shown, the connection lines of the indicator blocks in the graphical status indicator are straight lines, so the structure of the graphical status indicator can be considered to be a straight bar or straight line. It should be noted that when the graphical status indicator is a straight line, it can be placed horizontally, vertically or at a certain angle.

[0088] It should be noted that, regardless of the connection shape of the graphical status indicator, the shape of the indicator block can be a line in addition to a long strip. In this case, the graphical status indicator with an arc structure is similar to a dashboard. Figure 6B and 6C As shown, in the graphical status indicator, the shape of the indicator block can also be a circle and a trapezoid. Of course, the shape of the indicator block can also be other, not limited to the shape shown in the figure.

[0089] It can be seen from the above diagrams that no matter what form of graphical status indicator is used, it contains multiple indicator blocks, and different indicator blocks correspond to different parameter value partitions of physiological sign parameters. The change of parameter value can reflect the change of state of the monitored object under the physiological sign parameter. The change of quantity will cause the change of quality. The parameter value within a certain range can represent one state of the monitored object, such as the normal state, and the parameter value within another range can represent another state of the monitored object, such as the abnormal state. Therefore, the parameter value partitions of physiological indicators can be set according to clinical observation experience, and different parameter value partitions correspond to different physiological states.

[0090] It is understandable that the more parameter value partitions there are, the more physiological states are reflected, and the more detailed the monitoring content of the monitored object is. For example, the parameter value partitions may include two, representing the normal state and the abnormal state respectively. For another example, the parameter value partitions may include three, representing the normal state, the mild abnormal state and the severe abnormal state respectively.

[0091] In the above-mentioned embodiment, the measured value of the physiological sign parameter is displayed in the status indication area. In some embodiments, the monitoring interface may also include a measurement parameter display area, and the measurement parameter display area and the status indication area are two adjacent areas with the same border. The measured value is displayed in the measurement parameter display area.

[0092] Specifically, the measurement parameter display area and the status indication area are two separate areas, and the positional relationship between the two areas is an adjacent relationship. The adjacent relationship between the status indication area and the measurement parameter display area does not include a closed enclosing relationship, but may include a semi-enclosed enclosing relationship. More specifically, the measurement parameter display area is outside the arc of the status indication area, such as directly above or to the upper left of the status indication area, that is, the status indication area does not surround the measurement parameter display area.

[0093] In addition, the boundary line between the measurement parameter display area and the status indication area can be displayed together or hidden together, or one of them can be displayed and the other hidden.

[0094] The multiple indicator blocks of the graphical status indicator are arranged in a straight bar shape or an arc shape, and a parameter pointer is displayed in the status indication area. One end of the parameter pointer indicates the position of the indicator block corresponding to the parameter value interval to which the measured value belongs. Among them, the arc shape also shows that the graphical status indicator is not a closed circle, which further indicates that the graphical status indicator does not form a closed encirclement state for the measured value. For the description of the parameter pointer, please refer to the description of the above indicator icon, which will not be repeated here.

[0095] When the multiple indicator blocks of the graphical status indicator are arranged in an arc shape, one end of the parameter pointer can indicate the position of the indicator block corresponding to the parameter value interval to which the measured value belongs, and the other end can be displayed at the center position of the arc. This display effect is similar to an instrument panel, where the measured values ​​are the values ​​in the instrument panel, one end of the pointer is at the center position of the dial, and the other end points to the measured value in the instrument panel. It should be noted that the parameter pointer has this display style because the status indication area does not surround the measured value display area.

[0096] The multiple indicator blocks of the graphical status indicator are arranged in an arc shape in an orderly manner. In some embodiments, the arc shape may have a shape smaller than a semicircle, that is, the central angle of the arc is less than 180 degrees. In this way, the height of the graphical status indicator area can be limited, so that the measurement value can be displayed in a large font style to highlight the measurement value.

[0097] The large font display style of the measured value refers to the style that can affect the size of the area occupied by the measured value, such as font, font size, bold or not. In other words, in order to achieve the large font display style, the measured value can be displayed in a preset large font, preset large font size and bold. The large font display style can be used to provide a prominent reminder of the measured value.

[0098] In actual applications, in addition to observing the measured physiological state of the monitored object, monitoring needs to understand the historical physiological state of the monitored object. The combination of the two can provide medical staff with richer diagnostic basis. Therefore, the historical values ​​of physiological sign parameters can be analyzed and the analysis results can be displayed in the monitoring interface.

[0099] One analysis method is to perform distribution statistics on historical values. Specifically, the historical value of at least one physiological sign parameter of the monitored object within a preset time length is obtained; the historical value is distributed and counted based on at least one parameter value partition, and the distribution statistics result corresponding to the parameter value partition is determined; a segmented statistics area is provided on the monitoring interface, and the distribution statistics result is displayed in the segmented statistics area.

[0100] It is understandable that the historical values ​​of physiological sign parameters include a large number of historical values, and not all historical values ​​are instructive for the current diagnosis. According to the actual monitoring needs, the time length can be pre-set to limit the historical values ​​within which time to be obtained. For the convenience of description, the set time length can be called the preset time length.

[0101] It should be noted that the form of the preset time length is not limited, and it can be a continuous historical time period or multiple discontinuous historical time points. If it is a continuous time period, the end time point can be the current time point or a time point before the current time point. If it is multiple historical time points, the time points can be separated by the same time length or by different time lengths. It can be seen that the preset time length may not only refer to the length of a time window, but also include the location of the time window, that is, limit the start and end time positions of the time window.

[0102] After obtaining the historical values ​​of the physiological sign parameters, the historical values ​​are counted according to the pre-set parameter value partitions. It should be noted that the parameter value partitions can be time segments, or segmentation of the historical value range, or a combination of the two, or other segmentation conditions. It should be noted that the parameter value partitions here may be different from the parameter value intervals corresponding to the indicator blocks in the above-mentioned graphical status indicator.

[0103] If the parameter value is divided into multiple partitions, after the distribution statistics, each parameter value partition will get its own distribution statistics result. Of course, the parameter value partition can also be one, in which case, the entire historical value is equivalent to being regarded as a distribution statistics result.

[0104] The monitoring interface provides a segmented statistical area for displaying the distribution statistical results. The physiological sign parameters can be one or more. If there are multiple physiological sign parameters, the segmented statistical area can be divided into multiple sub-areas to display the distribution statistical results of different types of physiological sign parameters.

[0105] The historical values ​​may be numerous and the values ​​may vary. The historical values ​​are displayed in segments, and medical staff can understand the changes in the historical values ​​by comparing the distribution statistics of different parameter value partitions.

[0106] It should be noted that the preset time length corresponding to the historical value, the parameter value partition to be displayed, the physiological sign parameters to be displayed and other information may be preset by the system or may be set by the user independently.

[0107] Specifically, in response to the selection instruction input by the user, the distribution statistics of the historical values ​​of the target physiological sign parameter selected by the user are displayed in the segmented statistical area; the selection instruction represents the selection of the target physiological sign parameter concerned by the user and the preset time length corresponding to its historical value.

[0108] Among them, a selection operation control can be provided on the monitoring interface for the user to input a selection instruction. For example, the selection operation control can provide a selection item of a preset time length in the form of a drop-down list, and the user can select a certain selection item. In response to the selection instruction input by the user, the time length selected by the user is used as the preset time length. For another example, the selection operation control can provide options for multiple parameter value partitions, and the user can select a certain parameter value partition, and the segmented statistical area only displays the distribution statistical results corresponding to the selected parameter value partition. For another example, the selection operation control can provide multiple selection items for physiological sign parameters, and in response to the selection instruction input by the user, the physiological sign parameter selected by the user is used as the target physiological sign parameter.

[0109] The distribution statistics results can be displayed in the form of text or in the form of distribution statistics charts. The specific display methods are as follows.

[0110] In some embodiments, after obtaining the distribution statistics results, a distribution statistics chart may be generated according to the parameter value partitions and the distribution statistics results.

[0111] The distribution statistics result is the number or ratio of historical values ​​of the physiological sign parameter falling into each numerical interval in the historical values ​​within the preset time length. A distribution statistics chart is generated based on the parameter value partition and the distribution statistics result. For example, the distribution statistics chart is a histogram with the parameter value partition and the distribution statistics result as two coordinate axes, and the histogram can also be called a statistical histogram. Alternatively, the distribution statistics chart can include statistical charts such as pie charts, or statistical tables, etc.

[0112] See Fig. 7A, which shows an example of a monitoring interface. In addition to the status indication area 701, the monitoring interface also includes a segmented statistics area 702. The segmented statistics area 702 displays a histogram of blood oxygen saturation, which is obtained by segmenting the historical values ​​of blood oxygen saturation. From the description of the histogram, it can be seen that the historical value is the parameter value within 24 hours (h) before the current time point. It should be noted that the time length can be selected and set by the user, such as Fig. 7A The downward-pointing triangle icon in the figure can be clicked by the user to select the length of time provided.

[0113] The horizontal axis of the histogram is the four parameter intervals of blood oxygen saturation, which are [0-80%], [81%-90%], [91%-95%], and [96%-100%]. The vertical axis of the histogram is the ratio of the historical value of blood oxygen saturation to the total historical value in different blood oxygen saturation parameter intervals. By observing the histogram, medical staff can understand the blood oxygen statistics (SpO2 Statistic) of the monitored object in the past 24 hours: the number of blood oxygen saturation values ​​less than 80% accounts for 5% of the total, the number of blood oxygen saturation values ​​greater than 81% and less than 90% accounts for 15% of the total, the number of blood oxygen saturation values ​​greater than 91% and less than 95% accounts for 70% of the total, and the number of blood oxygen saturation values ​​greater than 96% and less than 100% accounts for 10% of the total.

[0114] It should be noted that the distribution statistics results may correspond to multiple parameter value partitions, and one (some) parameter value partitions have special significance relative to other parameter value partitions. The special significance may specifically be that it can provide guidance for medical staff to judge the physiological state of the monitored object. For the sake of ease of description, the parameter value partition with such special significance may be referred to as the target parameter value partition. The target parameter value partition may be the parameter value partition corresponding to the normal situation, or it may be the parameter value partition corresponding to the abnormal situation, or it may also be the parameter value partition to be achieved after treatment by medical means (wherein the parameter value partition to be achieved after treatment may be referred to as the treatment target partition, and other parameter value partitions may be referred to as non-treatment target partitions). The target parameter value partition may be a parameter value partition or partitions, which may be pre-set by the system, or may be selected and set by the user.

[0115] In order to distinguish the target parameter value partitions, the target parameter value partitions and / or the distribution statistics corresponding to the target parameter value partitions may be displayed in a display style different from that of other parameter value partitions. Fig. 7A Taking the blood oxygen statistics shown as an example, if the treatment target partition is [91%-95%], the background color is filled in the parameter interval. Of course, the display method of differentiation is not limited to color, and can also be differentiated by adding icons and symbols.

[0116] In order to provide medical staff with more information, in addition to displaying the measured values ​​of the physiological sign parameters, a display graph of the historical values ​​of the physiological sign parameters, such as a trend graph and / or a trend table, can also be displayed.

[0117] Specifically, a trend graph and / or trend table corresponding to the physiological sign parameters is obtained; a trend display area is provided on the monitoring interface, and the trend graph and / or trend table is displayed in the trend display area.

[0118] like Fig. 7A As shown in FIG. 1 , the monitoring interface includes a status indication area 701 and a segmented statistics area 702, and also includes a trend display area 703. The trend display area 703 includes trend graphs of three physiological sign parameters: blood oxygen saturation SpO2, pulse rate PR, and perfusion index PI. The trend graph may include the normal parameter value range of the physiological sign parameters, which may be indicated by shading and numerical values. Fig. 7A As shown, according to the numerical scale, the normal parameter value range of blood oxygen saturation SpO2 includes 91%-95%, the normal parameter value range of pulse rate PR includes 100bpm-200bpm, and the normal parameter value range of perfusion index PI is above 1.0.

[0119] The arrangement of the three trend graphs is not limited to this, and they can be arranged in any up-down order, or in other arrangement directions.

[0120] In addition, three trend graphs are generated from the historical values ​​of three physiological sign parameters. Fig. 7A From -2h (hour) and -1h (hour), we can see that the historical value is the parameter value within 2 hours before the current time point 0.

[0121] Alternatively, what is displayed in the trend display area is a trend table of historical values ​​of physiological sign parameters. In the implementation mode of the trend table, the historical values ​​of the physiological sign parameters may include parameter values ​​within non-continuous time periods. Specifically, the historical values ​​include: parameter values ​​of the physiological sign parameters at time points with multiple different preset time lengths from the current time point. It should be noted that the time points of the physiological sign parameters are different time lengths away from the current time point, but the time points of the physiological sign parameters can be separated by the same time length. In simple terms, the parameter value of a physiological sign parameter is obtained at regular intervals within the historical time period.

[0122] See Figure 7B , which shows another example of a monitoring interface. Fig. 7AThe difference is that the trend display area shows the trend table of blood oxygen saturation SpO2, pulse rate PR and perfusion index PI, and the trend table shows the parameter values ​​of blood oxygen saturation SpO2, pulse rate PR and perfusion index PI at multiple different historical time points. Among them, the time points (Time) are 6:30, 7:00, 7:30, 8:00, 8:30, 9:00, 9:30, and the time lengths between these multiple historical time points are fixed, which is 30 minutes. Of course, the time lengths can be other values ​​and are not limited to this. It should be noted that Figure 7B The time points in the sequence are arranged from top to bottom, and the time points are arranged farther and farther from the current time point. Of course, the order of the time points can be reversed, that is, the time points are arranged closer and closer to the current time point from top to bottom.

[0123] As time changes, the defined preset time length can be changed, so the historical value obtained is changed, and the displayed distribution statistics can be refreshed, and the refresh interval can be set by the user. Or, after obtaining new measurement data, the distribution statistics are refreshed synchronously, and the displayed chart is refreshed.

[0124] The number of records displayed in the trend table can be a preset fixed value, or can also be set to a value indicated by an instruction according to a setting instruction of the user. If multiple statistical records cannot be displayed at the same time, they can be displayed on multiple screens, and the user can view other statistical records contained in other screens through touch operation.

[0125] It should be noted that the trend graph and the trend table are two different trend diagrams, and one of them can be preset to be fixedly displayed in the trend display area. Alternatively, the trend graph and the trend table can be switched between each other, and the triggering instruction of the switching can be implemented by the user. Specifically, in response to the instruction input by the user, the trend graph or the trend table displayed in the trend display area is switched to the other.

[0126] In one example, a button, such as a physical button or a virtual button displayed on a display screen, may be provided on the medical device, and the user may trigger the button to select whether to display a trend graph or a trend table.

[0127] In another example, when the display screen of the medical device has a touch function, the way to input the command can be to slide on the display screen, such as sliding left or right, or sliding up or down. In order to facilitate the user to input accurate switching sliding instructions, the trend display area can also include a prompt icon to prompt the user in which direction to slide to trigger the display of another trend icon.

[0128] The display screen of the medical device includes a monitoring interface. The trend display area of ​​the monitoring interface currently displays a trend table. There are two circular icons below the trend table. The circular icon on the left is darker in color, and the circular icon on the right is lighter in color, indicating that the trend icon on the left is currently displayed. If you want to trigger the display of another trend icon, you need to swipe to the right. Based on the prompt, the user triggers the swipe right operation on the display screen, and the content displayed in the trend display area can be switched from a trend table to a trend chart. At the same time, the circular icons become lighter in color on the left and darker in color on the right. Of course, you can also switch in the opposite direction to switch the trend chart to a trend table.

[0129] In addition, in order to remind some abnormal parameter values ​​in the physiological sign parameters in the trend table, an alarm prompt can be issued. Specifically, the parameter value of the physiological sign parameter in the trend table is monitored, and if it is determined that the parameter value exceeds the corresponding parameter threshold, the parameter value is displayed based on a preset display style; or, the parameter value of the physiological sign parameter in the trend table is monitored, if the alarm information associated with the parameter value is monitored, the parameter value is displayed based on a preset display style; or, the trend table is displayed using a display style that can distinguish between normal and abnormal parameter values ​​of the physiological sign parameters in the trend table.

[0130] The alarm information may be an alarm condition defined according to an abnormal physiological state. If the parameter value of a physiological sign parameter triggers the alarm information, it is necessary to prompt the parameter value. For example, the alarm information related to blood oxygen saturation may include low blood oxygen saturation. If a certain parameter value of blood oxygen saturation triggers a low blood oxygen saturation alarm, it is necessary to prompt the parameter value of blood oxygen saturation. For another example, the alarm information related to pulse rate may include bradycardia, extreme bradycardia or hypocardia. If a certain parameter value of pulse rate triggers any of the above alarm information, the parameter value of pulse rate may be prompted.

[0131] In addition, the normal value range of the corresponding physiological sign parameter can be indicated by a shadow display in the trend chart; or the normal value range of the corresponding physiological sign parameter can be indicated by a ruler line in the trend chart.

[0132] See Figure 8 , which shows a structure of a physiological sign parameter display device provided by the present application. Figure 8 As shown, the device may specifically include: a physiological sign parameter acquisition module 801 , a display module 802 , a parameter value interval determination module 803 , and a processing module 804 .

[0146] In one embodiment, the display module 802 displays an indication icon at the position of the indication block corresponding to the parameter value interval to which the measurement value belongs.

[0149] In one embodiment, the distribution statistics result is: the number or number ratio of the historical values ​​of the physiological sign parameter within a preset time length that fall into the parameter value partitions respectively.

[0150] In one embodiment, the display module 802 generates a distribution statistics chart based on the parameter value partitions and the distribution statistics results.

[0151] In one embodiment, the distribution statistics chart is a histogram with the parameter value partitions and the distribution statistics results as two coordinate axes.

[0152] In one embodiment, the physiological sign parameter display device further comprises a setting module. The setting module responds to a selection instruction input by a user and displays the distribution statistics of the historical values ​​of the target physiological sign parameter selected by the user in the segmented statistical area; the selection instruction indicates the selection of the target physiological sign parameter concerned by the user and the preset time length corresponding to its historical value.

[0153] In one embodiment, the display module 802 determines a target parameter value partition, and displays the target parameter value partition and / or the distribution statistics corresponding to the target parameter value partition in a display style different from that of other parameter value partitions.

[0154] In one embodiment, the display module 802 obtains a trend graph and / or a trend table of the physiological sign parameters; provides a trend display area on the monitoring interface, and displays the trend graph and / or the trend table in the trend display area.

[0155] In one embodiment, the display module 802 switches the trend graph or trend table displayed in the trend display area to another one in response to a switching instruction input by the user.

[0156] In one embodiment, the display module 802 monitors the parameter value of the physiological sign parameter in the trend table, and if it is determined that the parameter value exceeds the corresponding parameter threshold, the parameter value is displayed based on a preset display style; or, the parameter value of the physiological sign parameter in the trend table is monitored, and if alarm information associated with the parameter value is monitored, the parameter value is displayed based on a preset display style; or, the trend table is displayed in a display style that can distinguish between normal and abnormal parameter values ​​of the physiological sign parameters in the trend table; or, in the trend chart, the normal value range of the corresponding physiological sign parameter is marked by a shaded display; or, in the trend chart, the normal value range of the corresponding physiological sign parameter is marked by a ruler line.

[0160] In one embodiment, the plurality of indicator blocks of the graphical status indicator are arranged in order to form an arc shape, and the other end of the parameter pointer is displayed at a position corresponding to the center of the arc.

[0161] The present application also provides a monitoring system, which may specifically include: a processor and a display.

[0162] The display is used to display information; the processor is used to execute program instructions to implement the various steps in the physiological sign parameter display method in the above embodiment.

[0163] The monitoring system mentioned in this application can be an independent device or a system formed by interconnecting multiple independent devices; the monitoring system is not limited to a monitor, but can also be an invasive / non-invasive ventilator, anesthesia machine, defibrillator, nurse station, central station and other equipment with monitoring functions, and of course, it can also be a computer terminal or mobile terminal that installs and runs clinical data monitoring and analysis software to implement the method provided in the above embodiments. The following embodiments are mainly described by taking a monitor as an example.

[0164] A specific example of a monitor is Fig. 9 shown. Fig. 9 A system framework diagram of a parameter processing module in a multi-parameter monitor is provided.

[0165] The multi-parameter monitor has an independent shell, and a sensor interface area is provided on the shell panel, in which multiple sensor interfaces are integrated for connecting with external physiological sign parameter sensor accessories 911. The shell panel also includes a small LCD display area, a display 918, an input interface circuit 920 and an alarm circuit 919 (such as an LED alarm area). The parameter processing module is used for external communication and power supply interfaces for communicating with the host and taking power from the host. The parameter processing module also supports an external parameter module, which can form a plug-in monitor host by inserting the parameter module. As a part of the monitor, it can also be connected to the host through a cable, and the external parameter module is an external accessory of the monitor. In addition, the multi-parameter monitor includes a memory 917 for storing computer programs and various data generated during the related monitoring process.

[0166] The internal circuit of the parameter processing module is placed in the housing, such as Fig. 9 As shown, it includes a signal acquisition circuit 912 corresponding to at least two physiological sign parameters, a front-end signal processing circuit 913 and a main processor 915.

[0167] The main processor 915 can implement each of the processing-related steps in the above-mentioned apnea event monitoring methods.

[0168] The signal acquisition circuit 912 can be selected from an electrocardiogram circuit, a respiratory circuit, a body temperature circuit, a blood oxygen circuit, a non-invasive blood pressure circuit, an invasive blood pressure circuit, etc. These signal acquisition circuits 912 are electrically connected to corresponding sensor interfaces, respectively, and are used to be electrically connected to sensor accessories 911 corresponding to different physiological sign parameters. The output end is coupled to the front-end signal processor, and the communication port of the front-end signal processor is coupled to the main processor, and the main processor is electrically connected to the external communication and power supply interface.

[0169] Various physiological sign parameter measurement circuits can adopt general circuits in the existing technology. The front-end signal processor completes the sampling and analog-to-digital conversion of the output signal of the signal acquisition circuit, and outputs a control signal to control the measurement process of the physiological signal. These parameters include but are not limited to: electrocardiogram, respiration, body temperature, blood oxygen, non-invasive blood pressure and invasive blood pressure parameters.

[0170] The front-end signal processor can be implemented by a single-chip microcomputer or other semiconductor devices, or by an ASIC or FPGA. The front-end signal processor can be powered by an isolated power supply, and the sampled data is simply processed and packaged, and then sent to the main processor through the isolated communication interface. For example, the front-end signal processor circuit can be coupled to the main processor 915 through the isolated power supply and the communication interface 914.

[0171] The reason why the front-end signal processor is powered by an isolated power supply is that the DC / DC power supply isolated by a transformer plays the role of isolating the patient from the power supply equipment. The main purposes are: 1. Isolate the patient. Through the isolation transformer, the application part is floated to make the patient leakage current small enough; 2. Prevent the voltage or energy during the application of defibrillation or electric knife from affecting the boards and devices of the intermediate circuit such as the main control board (guaranteed by creepage distance and electrical clearance).

[0172] The main processor completes the calculation of the physiological sign parameters, and sends the calculation results and waveforms of the parameters to the host (such as a host with a display, a PC, a central station, etc.) through the external communication and power supply interface. The external communication and power supply interface 916 can be one or a combination of the local area network interfaces composed of Ethernet, Token Ring, Token Bus, and the fiber distributed data interface (FDDI) as the backbone network of these three networks. It can also be one or a combination of wireless interfaces such as infrared, Bluetooth, wifi, WMTS communication, etc., or it can also be one or a combination of wired data connection interfaces such as RS232, USB, etc.

[0173] The external communication and power interface 916 can also be a combination of one or both of a wireless data transmission interface and a wired data transmission interface. The host can be any computer device such as the host of a monitor, an electrocardiograph, an ultrasonic diagnostic instrument, a computer, etc., and a monitoring device can be formed by installing the matching software. The host can also be a communication device, such as a mobile phone. The parameter processing module sends data to a mobile phone that supports Bluetooth communication through a Bluetooth interface to realize remote transmission of data.

[0174] In addition, the present application provides a readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, the method for displaying the above-mentioned various physiological sign parameters is implemented.
