Then, a researcher such as a doctor displays such information on the “PC 100 for data analysis” in FIG. 1 to perform various studies.
In this embodiment, information suitable for research can be displayed by an operator such as a researcher.
The details will be described below.

(When displaying information in a two-dimensional plot)
FIG. 8 is a schematic flow chart showing the main steps of displaying the above-mentioned information on the flow rate and the number of revolutions in a two-dimensional plot.
In addition, FIG. 12 shows the case where the X-axis is the rotation speed information of the motor 5 and the Y-axis is the flow rate information of the flow rate sensor 11, which is generated in the process of FIG. Is a two-dimensional plot diagram showing the correlation between the rotation speed information and the flow rate information for 24 hours.
The process of generating the “two-dimensional plot diagram” shown in FIG. 12 will be described in detail below.

First, in step (hereinafter referred to as “ST”) 1, a researcher such as a doctor visualizes the correlation between two data, for example, the rotation speed information of the motor 5 and the flow rate information of the flow rate sensor 11 as a set change. When it is desired to display, the data analysis PC 100 of FIG. 1 is requested to display the “two-dimensional plot” screen.
Specifically, for example, as the X axis and the Y axis in FIG. 12, the data name to be displayed (for example, the flow rate, the number of revolutions) and the time zone to be displayed (specified by year, month, day, hour, minute, second, for example, May 31st) Enter 8:36:6 seconds to 24 hours).

Then, it progresses to ST12. In ST12, the input data name to be displayed on the X-axis and Y-axis (for example, the number of rotations, the flow rate) and the data of the time zone to be displayed are stored in the “display basic information storage unit 131” in FIG.

Then, it progresses to ST13. In ST13, the "basic screen display processing unit (program) 132" of FIG. 5 operates and the storage unit ("flow rate information storage unit 112""rotation number information" of FIG. The data corresponding to the designated time zone is extracted from the data stored in the storage unit 111 ″).
Then, as designated, the rotation number information is arranged on the X axis and the flow rate information is arranged on the Y axis (this step is not shown), and among these data, the X axis data and the Y axis data of the same time information are The intersections are plotted by figures, for example, circles, and displayed as "plot data" on the screen.

Then, it progresses to ST14. In ST14, the "time zone division processing unit (program) 133" of FIG. 5 operates to divide a designated time zone, for example, 24 hours into a plurality of subdivided time zones.
The plurality of subdivision time zones are, for example, every 2 hours, and in the case of 24 hours, there are 12 subdivision time zones.
A specific example of this subdivision time zone is the circle marks T1 to T11 arranged at the bottom of the screen in FIG.
Then, these circle marks are displayed differently (not shown), for example, arranged in different colors. Specifically, they are arranged so that the colors become brighter with the passage of time.
In addition, in FIG. 12, it is not always necessary to use colors, and patterns may be used as long as they can be classified.

Further, in this step, the "plot data" of FIG. 13 corresponding to each of these subdivision time zones is given a corresponding "color" or the like.
Therefore, a large number of plot data are configured to visually change with time.
Therefore, the researcher can clearly understand the state that the correlation between the flow rate and the rotation speed, which is indicated by the plot data, changes with time.

Then, it progresses to ST15. In ST15, the "event display mark placement processing unit (program) 134" in FIG. 5 operates to associate the "event display mark A" with any time in the designated time zone as shown in FIG. ..
The "event display mark A" is an example of a time information display section, which is an intersection of the X axis and the Y axis shown in FIG. 12, and is specific time information existing at the intersection.

In the example of FIG. 12, the event display mark A indicates specific “plot data” included in the subdivision time zone T6. For example, the numerical value of the rotation speed information of the X axis is “1982 RPM” and the value of the Y axis is The numerical value in the flow rate information is "3.53 LPM".
Then, in the present embodiment, as shown in FIG. 12, the X-axis and Y-axis numerical information at the position of the event display mark A is displayed on the screen.
These specific numerical values are an example of “detailed information”.

The “event display mark A”, which is the intersection of the X axis and the Y axis in FIG. 12, can be moved and placed by the researcher at any position.
Therefore, for example, while observing the correlation between the flow rate and the number of revolutions on the screen of FIG. 12, confirm the details with the “plot data” corresponding to the subdivision time zone T6 (between 10 hours and 12 hours). When desired, simply move the “event display mark A” in FIG. 12 to the “plot data” portion on the screen, and display the X-axis rotation speed and Y-axis flow rate value at the intersection on the screen. Can be made.

Therefore, when researching the correlation between the rotation speed of the X-axis and the flow rate of the Y-axis, the researcher makes a correlation between the subdivided time zone T6 which is a specific time zone, for example, a part of 24 hours. It is possible to analyze a large flow of relationships and at the same time to grasp numerical values at extremely minute points specified by the "event display mark A".
Therefore, the device makes it easy to analyze the correlation between the two pieces of information (flow rate and rotation speed).

(When operating scroll bar C on the screen)
Now, as shown in FIG. 12, in the present embodiment, for example, a “scroll bar C” which is an operation unit capable of changing the time range of the information displayed on the display 104 is provided.
That is, for example, when it is specified in FIG. 12 that the information of the time zone of 24 hours is displayed, if all the information of the time zone is displayed on one screen, it becomes difficult for the researcher to visually recognize the information. Therefore, as shown in FIG. , Scroll bar C is displayed on the screen.
Then, the information displayed on the screen can be changed by operating the "scroll bar C".
FIG. 9 is a schematic flowchart showing an operation example of the scroll bar C on the screen.

First, in ST21, it is determined whether or not the scroll bar C has moved. When the scroll bar C has moved, the process proceeds to ST22.
In ST22, the “display plot data change processing unit (program) 135” of FIG. 5 operates to change the reference time of the plot data displayed on the screen according to the movement amount of the scroll bar C of FIG. ..
For example, when the scroll bar C before movement is displaying the data between 8 o'clock and 16 o'clock, the plot data being displayed is changed by advancing the scroll bar C from 10 o'clock to 18 o'clock.

In this way, since the scroll bar C is arranged on the same screen as the screen on which the information is displayed, the researcher can easily operate the scroll bar C, and the researcher needs the information of the necessary time zone. Accordingly, it can be displayed on the display 104 in an easily viewable state.

(When displaying the event display mark A in association with a special event)
As described above, the “event display mark A” can be selected by the researcher as an arbitrary point while referring to the information on the screen, but in the present embodiment, this “event display mark A” is not changed. Since it can be displayed in association with the special event of, it will be described below.

FIG. 10 is a schematic flowchart showing a main operation example when displaying the event display mark A in association with a special event, for example, drug administration or the like.
For example, a researcher who wants to display the “event display mark A” as the administration time of drug administration on the display 104 of the data analysis PC 100 in FIG. 2 and to study changes in the flow rate and rotation speed before and after the drug administration , ST31, the display of the selection screen for the contents of the “event display mark A” is input.

Then, the data analysis PC 100 displays the “event display mark content selection screen” as shown in FIG. 13 on the display 104.
FIG. 13 is a schematic diagram showing an example of the screen for selecting the contents of the event display axis.

On this "event display axis content selection screen", event data such as medication time during operation and artificial lung replacement time is displayed as event information.

Then, for example, the researcher selects “Medication of May 31, 2017 at 20:42:30” (Medical AAA) in FIG. 13.
In this example, the investigator selects to study changes in the correlation of data (such as flow rate and rpm) before and after drug AAA administration.
Then, in ST32, it is determined that the content data of the event display mark A has been selected, and the process proceeds to ST33.

In ST33, the “event display mark content selection execution processing unit (program) 136” in FIG. 5 operates and responds to the corresponding time based on the selection of the event display mark content selection screen (drug administration time, etc.) in FIG. The event display mark A is displayed on the screen.
Then, with the time of the event display mark A as a reference, the color of the "plot data" before or after that is set to a different color and has a different expression format.

In this way, by changing the color and the like before and after the event display mark A, a researcher who visually recognizes the screen can easily grasp the change in the correlation between the two pieces of information (flow rate and rotation speed, etc.).
In the present embodiment, “medicine administration time” is selected as the event display mark A, but the present invention is not limited to this, and other events such as artificial lung replacement may be selected.

(When you want to display the calculated data obtained by calculating various data on the screen)
FIG. 11 is a schematic flowchart showing the main steps of displaying the calculated data obtained by calculating various data on the screen.
First, a researcher displays special information, such as post-calculation data, which is special information obtained by calculating various data such as flow rate, on the screen as X-axis or Y-axis. If desired, go to ST41 in FIG.
In ST41, when the researcher requests the display of the calculation formula, the “calculation formula input calculation processing unit (program) 141” in FIG. 6 operates and the calculation formula input screen is displayed.

FIG. 14 is a schematic diagram showing the “calculation formula” displayed on the screen.
As shown in FIG. 14, on the calculation formula input screen, each data name (item name such as flow rate (Flow)) that can be used as a part of the formula and a numerical keypad for calculation are displayed.
Then, a calculation formula can be created using each of these data names and the numeric keypad.

When the item of each data name (flow rate, etc.) is taken into the formula, necessary data is extracted from the corresponding storage unit, for example, the flow rate information storage unit 112 or the like in the portion of the data name, and calculation is performed. Has become.

In the present embodiment, for example, the researcher desires to display the oxygen transport amount data on the screen with the X axis or the Y axis, and therefore inputs the following equation in the equation part of FIG.
“((1.36×SO ₂ ×Hgb)+(0.0031×PO ₂ ))×Flow”
Of these, for the “SO ₂ ”, “Hgb”, “PO ₂ ”, and “Flow” portions, the keys with the same names prepared in FIG. 14 are selected and input. Numerical values are input using the numeric keypad in FIG.

By inputting in this way, “SO ₂ ”is calculated by extracting data from the “oxygen saturation information storage unit 221” in FIG.
Similarly, “Hgb” is the “hemoglobin information storage unit 223” in FIG. 3, “PO ₂ ”is the “oxygen partial pressure information storage unit 225” in FIG. 3, and “Flow” is the “flow rate information in FIG. 3”. Data is extracted from the storage unit 112" and calculation is performed.

Therefore, in the present embodiment, by inputting the calculation formula on a special screen, the value of the oxygen transport amount or the like can be obtained by using the value of the data such as the flow rate actually acquired from the extracorporeal circulation device. , The device is extremely easy for researchers to use.

Further, in the present embodiment, the calculation formula has been described by taking the oxygen carrying amount as an example. However, in the case of “differential pressure”, it can be obtained by inputting the formula of “Press2-Press1”.

Then, the process proceeds to ST42, where it is determined whether or not the calculation formula is input. When the calculation formula is input, the process proceeds to ST43.
In ST43, the input calculation formula, in the case of the present embodiment, the oxygen transport amount formula “((1.36×SO ₂ ×Hgb)+(0.0031×PO ₂ ))×Flow” is shown in FIG. “Calculation formula data storage unit 142” of No.

Then, it proceeds to ST44. In ST44, the same calculation processing unit (program) 141 operates, and the data name of the calculation formula of the “calculation formula data storage unit 142” is the data of each storage unit. In the present embodiment, “oxygen saturation level” in FIG. Data of the information storage unit 221, the “hemoglobin information storage unit 223”, the “oxygen partial pressure information storage unit 225”, and the “flow rate information storage unit 112” are substituted and calculated, and the result is “after calculation” in FIG. The data is stored in the data storage unit 143”.

Then, it proceeds to ST45. In ST45, the post-calculation data in the “post-calculation data storage unit 143” in FIG. 6, for example, the oxygen carrying amount is displayed on the screen as X-axis or Y-axis data based on the corresponding time information.

As described above, in the present embodiment, the researcher can display the data necessary for the research on the screen instead of calculating the data himself, and can quickly compare the data with other data.
Therefore, the researcher can generate the data required for the research by the calculation formula and display the data on the screen, which is an extremely easy-to-use device.
