Then, researchers such as doctors display such information on the “data analysis PC 100” in FIG. 1 to conduct various researches.
In the present embodiment, the display of information suitable for research can be performed by the operation of an operator who is a researcher or the like.
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 flow rate and rotational speed information in a two-dimensional plot.
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 generated in the process of FIG. It is a two-dimensional plot which shows the correlation of rotation speed information and flow volume information between "" to 24 hours.
Hereinafter, the generation process of the “two-dimensional plot diagram” shown in FIG. 12 will be described in detail.

First, in step 1 (hereinafter referred to as “ST”), a researcher such as a doctor visualizes the correlation between two data, for example, the rotational 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 display of the “two-dimensional plot” screen is requested on the data analysis PC 100 of FIG.
Specifically, for example, as the X axis and the Y axis in FIG. 12, the data name (for example, flow rate, number of rotations) to be displayed and the time zone to be displayed (specified by year, month, day, hour, minute and second), for example, May 31 Enter 8: 36: 6 to 24 hours).

Next, the process proceeds to ST12. In ST12, the data names (for example, the number of rotations and the flow rate) to be displayed on the input X axis and Y axis and the data of the time zone to be displayed are stored in the "display basic information storage unit 131" in FIG.

Next, the process proceeds to ST13. In ST13, the "basic screen display processing unit (program) 132" of FIG. 5 operates, and the storage unit of the designated data name (flow rate, number of rotations) ("flow rate information storage unit 112" of FIG. Among the data stored in the storage unit 111 ′ ′), data corresponding to a designated time zone is extracted.
Then, as designated, the rotational speed information and the flow rate information are arranged on the X axis and the Y axis (this step is not shown), and among these data, the X axis and Y axis data of the same time information The points of intersection are plotted as figures, for example, by circles and displayed on the screen as “plot data”.

Next, the process proceeds to ST14. In ST14, the "time zone division processing unit (program) 133" in 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 two hours, and in the case of 24 hours, 12 subdivision time zones.
A specific example of this subdivision time zone is a circle of T1 to T11 arranged at the lower part of the screen of FIG.
And, these circles are displayed differently (not shown), for example, arranged in different colors. Specifically, the color is arranged to become brighter with the passage of time.
In addition, in FIG. 12, it is not necessary to be necessarily a color, and if it can be divided, it may be a pattern.

In addition, in this process, the “plot data” in FIG. 13 corresponding to each of the subdivision time zones is given a corresponding “color” or the like.
Therefore, a large number of plot data are configured to change visually depending on the time of day.
Therefore, the researcher can clearly understand the state in which the correlation between the flow rate and the rotation speed changes with time, as indicated by the plot data.

Next, the process proceeds to ST15. In ST15, the "event display mark placement processing unit (program) 134" of FIG. 5 operates, and "event display mark A" is made to correspond to an arbitrary time of the designated time zone as shown in FIG. .
The “event display mark A” is an example of the time information display unit, is an intersection of the X axis and the Y axis shown in FIG. 12, and is specific time information present at the intersection.

In the example of FIG. 12, the event indication mark A indicates a 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 Y axis The numerical value in the flow rate information is “3.53 LPM”.
Then, in the present embodiment, as shown in FIG. 12, numerical information on the X axis and Y axis at the position of the event display mark A is displayed on the screen.
These specific numerical values are an example of the "detailed information".

In addition, “event display mark A” which is an intersection point of the X axis and the Y axis in FIG. 12 is configured such that the researcher can move and arrange it at any position.
Therefore, for example, when observing the correlation between the flow rate and the number of revolutions on the screen of FIG. 12, confirm the details with "plot data" corresponding to the subdivision time zone T6 (between 10 hours and 12 hours) If you want to, just move "event display mark A" in Fig. 12 to the "plot data" part on the screen, and display the X axis rotation speed and Y axis flow rate value on the screen on the screen It can be done.

For this reason, when researching the correlation between the number of rotations of the X axis and the flow rate of the Y axis, the researcher is correlating the subdivision time zone T6 which is a specific time zone, for example, a partial time zone of 24 hours. A large flow of relationships can be analyzed, and at the same time, numerical values at extremely fine points specified by the "event indication mark A" can be grasped simultaneously.
Therefore, the apparatus is easy to analyze the correlation between two pieces of information (flow rate and rotational speed).

(When operating scroll bar C on the screen)
Now, as shown in FIG. 12, in the present embodiment, for example, “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 to display the information of the time zone of 24 hours in FIG. 12, if the information of the time zone is displayed on one screen, it becomes difficult for the researcher to visually recognize, as shown in FIG. , Scroll bar C is displayed on the screen.
Then, it is possible to change the information displayed on the screen by the operation of 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 the scroll bar C has moved. If the scroll bar C has moved, the process proceeds to ST22.
In ST22, the “display plot data change processing unit (program) 135” in 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 in FIG. .
For example, when the scroll bar C before movement is displaying data between 8 o'clock and 16 o'clock, by advancing the scroll bar C, the displayed plot data is changed from 10 o'clock to 18 o'clock.

As described above, since the scroll bar C is disposed 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 necessary time zone information. Accordingly, it can also 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 as an arbitrary point while the researcher refers to the information etc. on the screen, but in the present embodiment, the “event display mark A” is not 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 indication mark A in association with a special event such as drug administration.
For example, a researcher who wants to display "event display mark A" as the administration time of drug administration on the display 104 of the data analysis PC 100 shown in FIG. In ST31, the screen for selection of the contents of "event display mark A" is displayed and input.

Then, the data analysis PC 100 causes the display 104 to display an "event display mark content selection screen" as shown in FIG.
FIG. 13 is a schematic view showing an example of an event display axis content selection screen.

On the "event display axis content selection screen", data of an event such as a dosing time during surgery and an artificial lung replacement time are displayed as event information.

Then, for example, the researcher selects “May 31, 2017 20:42:30 seconds of medication (drug AAA)” in FIG.
In this example, a researcher chooses to study changes in the correlation of data (such as flow rate and number of revolutions) before and after dosing of the drug AAA.
Then, at 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" of FIG. 5 operates, and based on the selection of the event display mark content selection screen of FIG. 13 (the time of drug administration etc.) The event display mark A is displayed on the displayed screen.
Then, with reference to the time of the event display mark A, the color of “plot data” before or after that is made a different color, and is made a different expression form.

As described above, by changing the color or the like before and after the event display mark A, a researcher who visually recognizes the screen can easily understand the change in the correlation between the two pieces of information (flow rate, rotation speed, and the like).
In the present embodiment, the “agent 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 can also be selected.

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

FIG. 14 is a schematic view showing “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) can be used as a part of the formula, and a numerical keypad for calculation and the like are displayed.
Then, a calculation formula can be created using these data names and the ten keys.

When the items of each data name (flow rate etc.) are taken into a formula, necessary data is extracted from the corresponding storage unit, for example, flow rate information storage unit 112 etc., in the part of the data name, and calculation is performed It has become.

In the present embodiment, for example, the researcher desires to display the data of oxygen transport amount on the screen as the X axis or the Y axis, so the following equation is input to the equation of FIG.
_{"((1.36 × SO 2 × Hgb} ) + (0.0031 × PO 2)) × Flow "
Among them, “SO ₂ ”, “Hgb”, “PO ₂ ” and “Flow” are selected by selecting the key of the same name prepared in advance in FIG. The numbers are input using the ten keys of FIG.

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

Therefore, in the present embodiment, by inputting the calculation formula on a special screen, it is possible to obtain the value of the oxygen transport amount etc. using the value of the data such as the flow rate actually acquired from the extracorporeal circulation device. It has become an extremely easy-to-use device for researchers.

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

Next, in ST42, it is determined whether or not there is an input of a formula, and when there is an input of the formula, the process goes to ST43.
In ST43, the input calculation formula, in the case of the present embodiment, the oxygen transfer amount formula “((1.36 × SO ₂ × Hgb) + (0.0031 × PO ₂ )) × Flow” is shown in FIG. Are stored in the “calculation formula data storage unit 142”.

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

Next, the process proceeds to ST45. In ST45, the post-calculation data of the "post-calculation data storage unit 143" of FIG. 6, for example, the oxygen transport 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 without calculating the data himself and can quickly compare this with other data.
Therefore, the researcher can generate data necessary for the research by a calculation formula and display the data on the screen, which makes the apparatus extremely easy to use.
