[0009] FIG. 1 shows a patient management situation in an embodiment. Patient P is fitted with a ventilator VEN and a vital sign monitor BIM, both of which are medical devices ME. The image generation system of this embodiment includes multiple medical devices ME, such as the ventilator VEN and the vital sign monitor BIM, a display device D, and an image generation device 1. The ventilator VEN and the vital sign monitor BIM measure the patient P's condition to obtain various parameter values ​​for the patient monitor and transmit these values ​​to the image generation device 1. The image generation device 1 stores the received parameter values. A mouse M and a keyboard K are connected to the image generation device 1 as input devices, allowing medical personnel to operate the image generation device 1. Furthermore, blood drawn from patient P is measured by a blood gas analyzer BGA, also a medical device ME. The parameter values ​​for the patient monitor obtained through the measurement are input from the blood gas analyzer BGA to the image generation device 1 via the hospital network N.

[0010] The parameter values ​​of the blood gas analyzer BGA can also be input to the image generating device 1 via removable storage such as a USB. Alternatively, these parameter values ​​can be recorded by printing or writing down, and then manually entered using the mouse M and keyboard K while viewing the record.

[0011] The image generating device 1 generates a display image from parameter values ​​input from multiple medical devices ME and transmits it to the display device D. Blood drawn from a patient P is input into a blood gas analyzer BGA, and in this embodiment, the measured parameter values ​​are updated at the timing input to the image generating device 1 via the in-hospital network N and displayed on the display device D. In addition, the parameter values ​​of the ventilator VEN and the vital sign monitor BIM are continuously updated and displayed on the display device D.

[0012] In the embodiment shown in FIG. 1, the display device D is installed at the bedside, but the display device D may also be displayed on a display in a location other than the bedside within the hospital, or a tablet or the like carried by a medical professional may also be used as the display device D. The ventilator VEN, vital sign monitor BIM, and image generation device 1 may be partially or entirely placed under the bed, etc. The image generation device 1 may also be installed in a separate room. The mouse M and keyboard K may also be removed when not needed.

[0013] The biological information monitor BIM performs measurements and calculations using sensors attached to the patient P. Then, it transmits parameter values ​​such as oxygen saturation SpO2, end-tidal carbon dioxide partial pressure etCO2, vital signs BP, body temperature TEMP, and respiratory rate RR. The transmitted parameter values ​​are input to the image generation device 1.

[0014] The ventilator VEN performs measurements and calculations while performing artificial respiration according to the settings. It then transmits parameter values, such as the inhaled oxygen concentration FiO2, positive end-expiratory pressure PEEP, flow rate FR, tidal volume VT, plateau pressure PPLAT, driving pressure ΔP, mechanical power MP, airway resistance AR, compliance CP, and respiratory rate RR. The transmitted parameter values ​​are input to the image generation device 1.

[0015] Furthermore, the blood gas analyzer BGA measures and calculates the blood sample by placing it in the analyzer. The obtained parameter values ​​include arterial blood oxygen saturation (SaO2), arterial blood oxygen partial pressure (PaO2), arterial blood carbon dioxide partial pressure (PaCO2), and pH. These parameter values ​​are input to the image generating device 1 via the hospital network N connected to the blood gas analyzer BGA.

[0016] The image generating device 1 obtains the respiratory rate RR value from both the vital sign monitor BIM and the ventilator VEN. The image generating device 1 also calculates the arterial blood oxygen partial pressure PaO2 value obtained from the blood gas analyzer BGA and the inhaled oxygen concentration FiO2 value obtained from the ventilator VEN to calculate the P / F ratio PF.

[0017] The parameter value is a concept that includes not only values ​​of biological information obtained from the living body of the patient P (for example, blood pressure, respiratory rate, body temperature, pulse rate, etc. obtained from various sensors), but also setting information of the medical device ME that can estimate the biological information of the patient P (for example, PEEP, FiO2, tidal volume VT, etc. of the ventilator VEN). The setting information is basically changed by the setting operation of a medical professional, but it may also be automatically changed by the ventilator VEN depending on the patient's condition (for example, the value of the tidal volume VT is dynamically changed).

[0018] Figure 2 shows the configuration of the image generation device 1 according to an embodiment. The image generation device 1 includes a control unit 11 (CPU), a memory unit 12, an input device connection unit 13, multiple device connection units 14, a memory reading unit 15, and an image output unit 16, all of which are connected via a bus. The memory unit 12 stores computer programs for causing the image generation device 1 (a computer) to execute various procedures. These computer programs can be stored in the memory unit 12 via a computer-readable recording medium. The input device connection unit 13 is connected to a mouse M and a keyboard K, which are input devices. The multiple device connection units 14 are connected to a vital sign monitor BIM and an artificial ventilator VEN, respectively, and various parameter values ​​are input. Other devices can be connected to device connection units 14 that are not connected. Removable storage can be connected to the memory reading unit 15 to load settings, software, etc. The image output unit 16 is connected to a display device D, which outputs the display image.

[0019] In the memory unit 12, a tag is assigned to each parameter and the parameter value is saved. Medical device-specific tags and management object-specific tags are used as tags. Medical device-specific tags indicate the acquired medical device ME, and in the embodiment, the tags "BIM", "VEN", and "BGA" are assigned to the parameters. Management object-specific tags indicate the management object functions, and one or more of the tags "oxygenation function", "ventilation function", "work of breathing", "pulmonary mechanics", and "other" are assigned to the parameters. The control unit 11 generates a display image using the medical device-specific tags and management object-specific tags. [Example]

[0020] In the first embodiment, the display image for displaying by medical device shown in Fig. 3 and the display image for displaying by management subject shown in Fig. 4 can be generated by the image generation device 1 and switched between them and displayed on the display device D. By using the mouse M, which is an input device, to point to the "display switch" display in the upper right corner of the display image and clicking, the display for displaying by medical device and the display for management subject can be switched between.

[0021] FIG. 3 shows a display screen for displaying by medical device in Example 1. The display screen in FIG. 3 is a display image generated by the image generating device 1 shown in FIGS. 1 and 2, displayed on the display device D. In the display by medical device, parameter values ​​are displayed in a list arranged by the obtained medical device, with the current parameter values ​​displayed numerically, and the parameter values ​​up to the current time being displayed are displayed as trends using a line graph or dot graph. Note that the example of SpO2 and etCO2 shown in FIG. 3 is a line graph. In the display by medical device in Example 1, the image generating device 1 uses medical device tags to display multiple individual parameter images Pr arranged by medical device, and generates a display image that simultaneously displays multiple medical device images, which is displayed on the display device D.

[0022] In FIG. 3 , an individual parameter image Pr displaying one parameter, SpO2, is shown at the top surrounded by a dotted line. The individual parameter image Pr is horizontally long, and the display contents, from the left, are the parameter name, the current parameter value, and a trend display using a line graph, etc. The parameter value and trend display are written within the frame. The "098" shown in FIG. 3 indicates that the current parameter value of SpO2 is 98%. Below the individual parameter image Pr for SpO2, an individual parameter image Pr for etCO2 is shown. The current parameter value of etCO2 is 44 mmHg. The individual parameter images Pr for other parameters below BP are also horizontally long, and the display contents are similarly displayed for each individual parameter image Pr. In FIG. 3 , the parameter values ​​and trend displays are omitted for the individual parameter images Pr for other parameters below BP. As described above, in the display image for the medical device-specific display in Example 1, multiple individual parameter images Pr are displayed vertically in a list.

[0023] In the medical device display shown in Figure 3, the individual parameter images Pr, from SpO2 to RR, display parameters obtained from the patient monitor BIM and are arranged together as a medical device-specific image. The individual parameter images Pr below, from FiO2 to RR, display parameters obtained from the ventilator VEN and are arranged together as a medical device-specific image. The individual parameter images Pr below that, from SaO2 to pH, display parameters obtained from the blood gas analyzer BGA and are arranged together as a medical device-specific image. In Figure 3, multiple individual parameter images Pr are arranged side by side as a medical device-specific image. The parameter value for PF, shown at the bottom, is calculated by the image generation device 1 from the arterial blood oxygen partial pressure (PaO2) value obtained from the blood gas analyzer BGA and the inhaled oxygen concentration (FiO2) value obtained from the ventilator VEN.

[0024] FIG. 4 shows a display screen of the management object display in Example 1. The display screen in FIG. 4 is a display image generated by the image generation device 1 shown in FIGS. 1 and 2, displayed on the display device D. In the management object display in Example 1, parameter values ​​obtained from the medical device ME are displayed in a list, arranged according to the management object functions of the patient P. For each parameter, the currently displayed parameter value is displayed numerically, and the parameter values ​​up to the currently displayed time are displayed as a trend using a line graph, a dot graph, or the like. Note that the example of PF and FiO2 shown in FIG. 4 is a line graph. In the management object display in Example 1, the image generation device 1 uses management object tags to generate multiple management object images, each displaying a group of multiple individual parameter images Pr by management object, and generates and displays a display image that simultaneously displays multiple management object images. In FIG. 4, each management object image is a collection of images of multiple individual parameter regions.

[0025] 3, the individual parameter image Pr in the embodiment shown in Fig. 4 is horizontally long, and the display contents are, from the left, the parameter name, the currently displayed parameter value, and a trend display using a line graph, etc. A list is generated by arranging multiple individual parameter images Pr vertically. The display by management subject is basically a display in which the order of multiple individual parameter images Pr in the display by medical device is grouped and displayed by management subject.

[0026] In the display by managed object in Figure 4, "PF" written at the top left corner is the parameter name, and "150" to the right of it is the current parameter value. The line graph to the right of the parameter value is a trend display up to the present time. The parameter value and trend display are written in a box. The parameter value of PF is calculated by the image generation device 1 from the arterial blood oxygen partial pressure (PaO2) value obtained by the blood gas analyzer BGA and the inhaled oxygen concentration (FiO2) value obtained by the ventilator VEN. The current parameter value for FiO2 is 0.4. Parameter values ​​and trend displays below FiO2 are omitted.

[0027] In Figure 4, PF through RR are displayed as an "oxygenation function" managed object image, which includes the individual parameter images Pr of oxygenation function, including the areas to the right of these parameter names. Furthermore, PEEP through etCO2 are displayed as a "ventilation function" managed object image, which includes the individual parameter image Pr areas of ventilation function, including the areas to the right of these parameter names. Below that, PPLAT through MP are displayed as a "work of breathing" managed object image, which includes the individual parameter image Pr areas of work of breathing, including the areas to the right of these parameter names. Furthermore, AR through CP are displayed as a "pulmonary mechanics" managed object image, which includes the individual parameter images Pr of pulmonary mechanics, including the areas to the right of these parameter names. BP through pH are displayed as an "other" managed object image, which includes the areas to the right of these parameter names.

[0028] PEEP and RR are parameters common to the oxygenation function and ventilation function, and are included in two managed object images, "oxygenation function" and "ventilation function." Individual parameter images Pr included in multiple managed object images are arranged and displayed together as a common managed object image CI, as shown by the dotted frame. PEEP and RR are assigned two managed object tags, "oxygenation function" and "ventilation function," and are therefore displayed together as a common managed object image CI. In Example 1, RR displays the average value of the RR parameter values ​​obtained from the patient information monitor BIM and the ventilator VEN.

[0029] The individual parameter images Pr from PF to SaO2 in the management object specific image for "oxygenation function" are parameters of only the oxygenation function, and are displayed together as a specific management object image PI, as shown in the dotted frame. Also, the individual parameter images Pr from VT to etCO2 in the management object specific image for "ventilation function" are parameters of only the ventilation function, and are displayed together as a specific management object image PI, as shown in the dotted frame. Individual parameter images Pr that are not included in multiple management object specific images are displayed together as a specific management object image PI. In the example of Figure 4, a common management object image CI that is common to "oxygenation function" and "ventilation function" is displayed between the specific management object image PI for only the "oxygenation function" and the specific management object image PI for only the "ventilation function".

[0030] In the example of Figure 4, the "work of breathing" management object specific images from PPLAT to MP are not included in other management object specific images and are "work of breathing" specific management object images PI. Similarly, AR and CP are "pulmonary mechanics" specific management object images PI. In addition, "other" management object specific images from BP to pH are also arranged and displayed together as specific management object images PI. By arranging them together by management object function and displaying them together as management object specific images, medical professionals who view the management object specific display shown in Figure 4 can easily understand the status of each of patient P's management object functions.

[0031] As described above, the management object-specific image for "oxygenation function" includes a specific management object image PI for "oxygenation function" that displays parameter values ​​that are not shared with other management object-specific images, and a common management object image CI that displays parameter values ​​that are also included in the management object-specific image for "ventilation function." Furthermore, the management object-specific image for "ventilation function" includes a specific management object image PI for "ventilation function" that displays parameter values ​​that are not included in other management object-specific images, and a common management object image CI that displays parameter values ​​that are also included in the management object-specific image for "oxygenation function." The common management object image CI is then displayed between the specific management object image PI for "oxygenation function" and the specific management object image PI for "ventilation function." This allows medical professionals viewing the management object-specific display to easily grasp the status of patient P for each management object function.

[0032] The display by management object in Fig. 4 makes it easy to grasp the status of patient P for each management object function. However, some medical professionals may be more familiar with the display by medical device shown in Fig. 3. Therefore, in Example 1, by moving the cursor with mouse M and clicking "display switch" in the upper right corner of the display image, it is possible to switch between the display by medical device shown in Fig. 3 and the display by management object shown in Fig. 4.

[0033] The storage unit 12 of the image generation device 1 stores a computer program for causing a computer to execute an input procedure for inputting multiple parameter values ​​for patient monitoring from multiple medical devices ME, and a screen generation procedure for generating a display image for management-related display in which the parameter values ​​are grouped and arranged for each management target. This computer program can be recorded on a computer-readable recording medium. The image generation method includes inputting the parameter values ​​from multiple medical devices that output parameter values ​​for patient monitoring, and generating a display image for management-related display in which the parameter values ​​are grouped and arranged for each management target function.

[0034] <Modification> In the first embodiment, the display can be switched between the management target display in FIG. 4 and the medical device display in FIG. 3. However, only the management target display as shown in FIG. 4 may be displayed. In the first embodiment, the boundaries of the management target images are not displayed in the management target display shown in FIG. 4. However, the boundaries of the management target images may be displayed by displaying a frame or a colored background. Furthermore, it may be indicated by text or the like which area corresponds to which management target function. In the medical device display in FIG. 3, the boundaries of the medical devices may be displayed, or text may be used. Furthermore, the management target display may be only the management target images of the specific management target images PI without the common management target images CI. [Example]

[0035] Fig. 5 shows a display screen of the management subject display in Example 2. The display screen in Fig. 5 is a display image generated by the image generation device 1 shown in Figs. 1 and 2, displayed on the display device D. In the management subject display in Example 2, parameter values ​​obtained from the medical devices are displayed as a radar chart arranged according to the management subject functions of the patient P. In Example 2, the display of some of the parameter values ​​sent from the medical devices ME is omitted to form the display image.

[0036] 5 in Example 2 shows a plurality of regular dodecagons of different sizes that share a common center C. The names of 12 parameters are displayed in a ring shape around the outside of the dodecagon, and the parameter values ​​of each parameter are connected and displayed as a radar chart in the display area of ​​the dodecagon. A thick solid broken line on the radar chart indicates the parameter value at the current time being displayed, and a dotted broken line indicates the average parameter value over a predetermined time period up to the current time being displayed.

[0037] The five parameters from PF on the left to RR going to the top right indicate that the managed function is "oxygenation function." Additionally, the four parameters from PEEP at the top to PaCO2 going to the right indicate that the managed function is "ventilation function." Furthermore, from PPLAT to MP at the bottom indicate that the managed function is "work of breathing." The dotted arc on the periphery indicates the range of managed functions, and the name of the managed function is displayed over the arc.

[0038] In the second embodiment, the management object-specific image, the specific management object image PI, and the common management object image CI are fan-shaped, and are combined to form a display image. The individual parameter image Pr is also fan-shaped. FIG. 6 shows the management object-specific image for the ventilation function in the second embodiment. The management object-specific image is fan-shaped spreading from a center C. The specific management object image PI for the ventilation function and the common management object image CI common to the oxygenation function are also fan-shaped. In the management object-specific display of the second embodiment, multiple management object-specific images that display parameter values ​​by management object are generated using the management object-specific tags assigned to each parameter, and a display image that simultaneously displays multiple management object-specific images is generated and displayed. Since the second embodiment is a radar chart display, the fan-shaped display of the management object-specific image, etc. is displayed with a line connecting the positions of the parameter values ​​to the fan-shaped display of the adjacent management object-specific image, etc.

[0039] In Figure 5, the sector-shaped area indicated by the thick, long, dotted arc from PF to RR is the management object image for "oxygenation function," and the sector-shaped area indicated by the thick, short, dotted arc from PEEP to PaCO2 is the management object image for "ventilation function." The sector-shaped area indicated by the thick, dashed-dotted arc is the management object image for "work of breathing." Furthermore, the sector-shaped area from PF to PaO2 is the specific management object image PI for "oxygenation function," and the sector-shaped area from PEEP to RR is the common management object image CI for "oxygenation function" and "ventilation function." Looking at the management object image displayed in the radar chart format shown in Figure 5, healthcare professionals can easily grasp the status of each of patient P's management object functions.

[0040] <Modification> In the second embodiment, the fan-shaped managed object-specific images, the specific managed object images PI, and the common managed object images CI are displayed so that the areas can be identified by using arc-shaped dotted lines or the like around the periphery. However, other display methods, such as color regions, character display colors, or line display colors, may be used to display the areas so that the areas can be identified. Furthermore, the solid and dotted lines in the second embodiment connect the parameter values ​​at the current time being displayed with the average parameter values ​​over a predetermined time period up to the current time being displayed. However, other parameter values, such as parameter values ​​from a predetermined time ago, may also be connected to display a radar chart. Furthermore, the managed object-specific images, including only the specific managed object images PI, may be displayed without the common managed object images CI. Furthermore, the parameter values ​​displayed in the radar chart may be normalized to fit within a normal range. [Example]

[0041] Fig. 7 shows a display screen for displaying by management subject in Example 3. The display screen in Fig. 7 is a display image generated by the image generation device 1 shown in Figs. 1 and 2, displayed on the display device D. In the display by management subject in Example 3, parameter values ​​obtained from the medical devices ME are grouped and arranged by the management subject functions of the patient P and displayed in a Venn diagram. In Example 3, the display of some of the parameter values ​​sent from the medical devices ME is omitted to form the display image.

[0042] In the Venn diagram display of Fig. 7 in Example 3, the area inside each circle is a management target specific image. The areas in the management target specific image that do not overlap with other circles are specific management target images PI, and the areas that overlap with other circles are common management target images CI. The management target specific display image is expressed as a Venn diagram with multiple closed curves, and the parameter values ​​for the same management target function are displayed inside the corresponding closed curve, displaying multiple parameter values ​​in the Venn diagram. The name of the management target function indicating the management target function is displayed in each circle.

[0043] The specific management object image PI for "oxygenation function" displays the parameter values ​​of PF, FiO2, SpO2, and PaO2 as numerical values. The common management object image CI for "oxygenation function" and "ventilation function" displays RR, and the common management object image CI for "oxygenation function," "ventilation function," and "work of breathing" displays PEEP. The specific management object image PI for "ventilation function" displays etCO2, PaCO2, and VT, and the specific management object image PI for "work of breathing" displays PPLAT, ΔP, and MP. In the management object-specific display of Example 3, multiple management object-specific images displaying parameter values ​​by management object are generated using management object-specific tags assigned to each parameter, and a display image displaying multiple management object-specific images simultaneously is generated and displayed.

[0044] In the third embodiment, the parameter names and parameter values ​​are displayed inside the closed curve, but it is sufficient if the parameter values, etc. that have the same managed function are associated with the inside of the corresponding closed curve and displayed in the Venn diagram. For example, the parameter values, etc. may be displayed outside the closed curve, or a line may be drawn from the inside to the outside of the closed curve and the parameter values, etc. may be displayed at the end of the drawn line. [Example]

[0045] Fig. 8 shows a display screen of the management subject display in Example 4. The display screen in Fig. 8 is a display image generated by the image generation device 1 shown in Figs. 1 and 2, displayed on the display device D. In the management subject display in Example 4, parameter values ​​obtained from the medical devices ME are displayed in a list, arranged according to the management subject functions of the patient P. For each parameter, the parameter value at the current time being displayed is displayed numerically, and the parameter values ​​up to the current time being displayed are displayed as a trend using a line graph, a dot graph, or the like. In Example 4 as well, the image generation device 1 generates a display image of the management subject display using a management subject tag assigned to each parameter.

[0046] 8, the individual parameter image Pr of this embodiment is horizontally long, similar to Example 1. From the left, the parameter name, the currently displayed parameter value, the upper and lower limits of the appropriate range, a trend display such as a line graph, a histogram of parameter values ​​over a predetermined period, and the appropriate range rate over the predetermined period in % are displayed.

[0047] The upper and lower limits of the appropriate range are indicated by numerical values, and the appropriate range is indicated by two horizontal lines at the top and bottom of the trend display. The vertical line with an arrow at the end shown in the trend display is a predetermined period setting bar indicating the predetermined period, with the area to the right of the vertical line being the predetermined period. The predetermined period can be changed by moving the predetermined period setting bar left or right with the mouse M. The length of the predetermined period can be confirmed by the numerical value displayed at the end of the arrow on the predetermined period setting bar. In Figure 8, the predetermined period is set to 10 hours. The predetermined period can also be set as a fixed value or by directly entering the value from the keyboard K. In this case, it is not necessary to display the predetermined period setting bar, etc.

[0048] The histogram displayed to the right of the trend display shows the distribution of parameter values ​​over a specified period. The appropriate range rate to the right of it indicates the percentage of time that the parameter value is within the appropriate range over the specified period. The horizontal lines representing the upper and lower limits of the appropriate range and the histogram show the degree to which the parameter value is within the appropriate range, and are an indication of appropriate range suitability. The appropriate range rate also indicates appropriate range suitability.

[0049] In Figure 8, PF indicates that the parameter value is within the appropriate range for 90% of the specified period. FiO2, etc., indicates that the parameter value is within the appropriate range for 100% of the specified period. The display range of the trend display can be moved left and right using the scroll bar at the bottom.

[0050] The display of appropriate range suitability may be other displays in addition to the histogram and appropriate range percentage shown in FIG. 8. For example, it may be the time during which the parameter value is within the appropriate range or the time during which it is not within the appropriate range (deviation period) during a predetermined period. Furthermore, instead of a histogram, the appropriate range suitability may be displayed by showing a box plot or the like together with horizontal lines representing the upper and lower limits of the appropriate range. In addition to this, the appropriate range suitability may be expressed by other statistical notations.

[0051] In Figure 8, the oxygenation tab on the left side is selected, and a sheet of images by management item showing the oxygenation function of patient P is displayed. In addition to the oxygenation tab, the lung protection, ventilation, and work of breathing / pulmonary mechanics tabs can be selected. This allows switching to a sheet showing images by management item of patient P's lung protection function, ventilation function, and work of breathing / pulmonary mechanics. Sheets can be switched by placing the cursor on a tab and clicking the mouse M.

[0052] In the display by management object in the fourth embodiment, a plurality of images by management object that display parameter values ​​by management object are generated, and the plurality of images by management object are displayed by switching between them. Therefore, if there is a common management object image CI, the common management object image CI is displayed on a plurality of sheets.

[0053] <Modification> Fig. 9 shows a display screen for displaying by management subject in a modified example of Example 4. The display screen in Fig. 9 is a display image generated by the image generation device 1 shown in Figs. 1 and 2, displayed on the display device D. In the display by management subject of the modified example, parameter values ​​obtained from the medical device ME are also displayed in a list, arranged according to the management subject functions of the patient P. For each parameter, the parameter value at the current time being displayed is displayed numerically, and the parameter values ​​up to the current time being displayed are displayed as a trend using a line graph, a dot graph, etc.

[0054] On the display screen of the modified example, the oxygenation function sheet is displayed by selecting a tab. PF to PEEP at the top of this sheet are oxygenation function parameters and are displayed in detailed view. In detailed view, as in Example 4, each parameter is displayed numerically as a current parameter value and as a trend. It also displays the appropriate range, a histogram, and appropriate range compatibility, and also displays a bar for setting a predetermined period. Meanwhile, RR to ΔP at the bottom are displayed in simplified view. In simplified view, only the current parameter values ​​are displayed. The parameters displayed at the bottom are parameters other than the oxygenation function, and hidden parameters can be displayed by scrolling up and down using the vertical scroll bar on the right.

[0055] In the modified example, multiple images for each management target are also displayed by switching between them. However, in the display for each management target in the modified example, the selected management target functions are displayed in detail, and the unselected management target functions are displayed in a simplified manner. The simplified manner displays only a portion of the detailed manner, and the detailed manner and simplified manner are not limited to those shown in FIG. 9.

[0056] In the fourth embodiment and the modified example, the displayed images for each management target are switched by selecting a tab.
