First Embodiment
[overview]
The information presentation device, information presentation method, and program of this embodiment will be described below using a blood coagulation testing device as an example.
The blood coagulation test device of this embodiment is a device for performing blood coagulation tests. Under normal conditions, blood circulates without clotting within blood vessels and clots outside of blood vessels. On the other hand, in cases such as thrombosis, blood tends to clot within blood vessels, and in cases such as hemophilia, abnormalities occur in which blood tends to clot less even when it is extravascularly.
The blood coagulation test apparatus of this embodiment performs measurements on samples to test the degree of abnormality related to blood coagulation for each sample (blood coagulation test).

Measurement items in the blood coagulation test of this embodiment include, for example, prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fbg), lupus anticoagulant (LA), and diluted Russell's viper venom time (dRVVT). In the blood coagulation test of this embodiment, measurements are performed on a predetermined number of measurement items selected from the above measurement items. There are no particular limitations on the number of measurement items selected.

The blood coagulation test device corresponds to the scattered light method, which is an optical detection method. In the scattered light method, light is irradiated onto a reaction vessel into which a sample and a reagent have been dispensed. A coagulation reaction occurs in the reaction vessel as the sample and the reagent are mixed, and as the coagulation reaction progresses, the turbidity of the mixture increases. As the turbidity of the mixture increases, the amount of scattered light of the irradiated light increases. The blood coagulation test device measures the change in the amount of scattered light over measurement time.
Absorbance spectroscopy is also known as an optical detection method. Absorbance spectroscopy is a detection method in which a change in the amount of transmitted light irradiated onto a reaction vessel into which a sample and a reagent have been dispensed is measured over a measurement period. The blood coagulation test apparatus of this embodiment may be adapted to perform tests using such absorbance spectroscopy. In the following description, an example will be given in which the blood coagulation test apparatus of this embodiment is configured to perform measurements using scattered light spectroscopy.

[Example of functional configuration of blood coagulation testing device]
1 shows an example of the functional configuration of a blood coagulation test apparatus 100 according to this embodiment. The blood coagulation test apparatus 100 may be configured to include, as hardware, a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and storage devices such as HDDs (Hard Disk Drives) and SSDs (Solid State Drives). The functions of the blood coagulation test apparatus 100 shown in the figure are realized by the CPU included in the blood coagulation test apparatus 100 executing a program.
The blood coagulation test apparatus 100 in the figure includes a measurement unit 101 , a control unit 102 , a storage unit 103 , an operation unit 104 , and a display unit 105 .

The measurement unit 101 is a part that measures samples corresponding to blood coagulation tests. The measurement unit 101 can store a predetermined number of reaction vessels into which samples have been dispensed. The measurement unit 101 dispenses reagents into the stored reaction vessels and irradiates light from a light source onto the reaction vessels containing the mixture of sample and reagent. The measurement unit 101 measures the amount of scattered light at measurement times (for example, approximately 0.1 seconds) corresponding to each predetermined measurement item. The measurement unit 101 outputs measurement result information related to the measurement results to the control unit 102.

The control unit 102 executes various controls in the blood coagulation test apparatus 100 .
The control unit 102 controls the measurement operation of the measurement unit 101 .
Furthermore, the control unit 102 acquires the measurement result information for each sample output from the measurement unit 101 , and stores the acquired measurement result information in the measurement result information storage unit 131 .
Furthermore, the control unit 102 uses the measurement result information for each sample stored in the measurement result information storage unit 131 to cause the display unit 105 to display a measurement result screen that presents the measurement results for each sample.

The control unit 102 includes a measurement result acquisition unit 121 and a display control unit 122. Note that the additional item estimation unit 123 corresponds to a modified example, and therefore its description will be omitted here.

The measurement result acquisition unit 121 acquires measurement result information indicating the measurement results obtained by measuring a sample using the measurement unit 101. The measurement result information corresponding to a sample includes the measurement values for each measurement item. The measurement result acquisition unit 121 stores the acquired measurement result information in the measurement result information storage unit 131.

The display control unit 122 controls the display on the display unit 105. The display control unit 122 uses the measurement result information stored in the measurement result information storage unit 131 to cause the display unit 105 to display a measurement result screen showing the measurement results for each sample.

The storage unit 103 stores various types of information corresponding to the blood coagulation test apparatus 100. The storage unit 103 includes a measurement result information storage unit 131.
The measurement result information storage unit 131 stores the measurement result information for each sample.

Note that the simplified waveform data storage unit 132 corresponds to the second embodiment, and therefore its description will be omitted here. In the first embodiment, the simplified waveform data storage unit 132 may be omitted.

2 shows an example of measurement result information corresponding to one sample stored in the measurement result information storage unit 131. The measurement result information in the figure includes fields for the sample ID, measurement date and time, measurement result, and additional information.
The sample ID field stores a sample ID that uniquely identifies the corresponding sample.
The measurement date and time field stores the date and time (measurement date and time) when the corresponding sample was tested (measured) by the blood coagulation test apparatus 100.
The measurement result field stores the measurement results for the corresponding sample. The measurement result field stores the measurement values for each of a plurality of measurement items (1 to n).
The incidental information field stores information (incidental information) associated with the measurement of the corresponding sample. The incidental information may include, for example, information regarding the occurrence of an abnormality related to the hardware of the blood coagulation test apparatus 100 (such as an emergency shutdown or a decrease in the light intensity of the light source lamp) or information regarding the occurrence of an error related to the measurement (such as a deviation of the measurement value from the reference range).

Returning to FIG.
The operation unit 104 includes various operators and input devices included in the blood coagulation test apparatus 100. The operation unit 104 may also include an input device connected to the blood coagulation test apparatus 100. The operation unit 104 outputs operation signals corresponding to operations performed on the various operators and input devices to the control unit 102. The control unit 102 executes processing corresponding to the input operation signals.

The display unit 105 displays images according to the control of the control unit 102.

[About the measurement results screen]
The blood coagulation test apparatus 100 of this embodiment can display a measurement result screen on the display unit 105 using the measurement result information for each sample stored in the measurement result information storage unit 131 ( FIG. 2 ).

3 shows an example of the measurement result screen, in which sample unit areas AR1 corresponding to each measured sample are arranged vertically.
In one specimen unit area, a specimen area and areas for a plurality of measurement items (PT, APTT, Fbg, AT, etc.) are arranged in the horizontal direction.

In the sample area, a sample ID that uniquely identifies the corresponding sample is displayed.

Each measurement item area shows the measurement results for the corresponding measurement item. Specifically, in one measurement item area, a measurement value area AR11, a waveform area AR12, and a flag area AR14 are arranged.

The measurement value area AR11 shows the measurement value of the corresponding measurement item. The measurement values shown in the measurement value area AR11 include the coagulation time.
The waveform area AR12 is an area where a waveform (measured waveform) based on the measurement results of the corresponding measurement item is displayed. Specifically, the waveform in the waveform area AR12 may be a waveform obtained based on measurements obtained by measuring the amount of scattered light over a measurement time (e.g., every 0.1 seconds) in a coordinate space with time on the horizontal axis and the amount of scattered light on the vertical axis. The figure shows an example in which a clot waveform is displayed as the measured waveform in the waveform area AR12.
The flag area AR14 is an area where an analysis flag is displayed. The analysis flag (an example of a symbol) indicates the analysis result of the measurement result. The analysis flag may include information estimated regarding the condition of the sample or drug administration based on the analysis of the measurement result, such as the analysis of the waveform shown in the waveform area AR12.
One of the sample conditions indicated by the analysis flags is a deficiency of coagulation factor VIII. Coagulation factor VIII is known as the deficient factor in hemophilia A, a bleeding disorder, and a deficiency of coagulation factor VIII results in a significant bleeding tendency. The "GES (GEntle Slope)" shown in flag area AR14 of Figure 3 suggests a deficiency of coagulation factor VIII as a sample condition. Another sample condition is a thrombotic disorder. The anticoagulant argatroban is sometimes administered to treat a thrombotic disorder. The "NSM (Non-SigMoid)" shown in flag area AR14 of Figure 3 suggests that argatroban is being administered to a patient with a thrombotic disorder.
Furthermore, if multiple analysis results are obtained for a corresponding measurement item, multiple analysis flags corresponding to the respective analysis results may be displayed in flag area AR14.

The analysis flag may be, for example, a character string that simplifies the corresponding information (such as an abbreviation or contraction), or it may be a symbol (mark or indication) that indicates the corresponding information. The figure shows an example in which the analysis flag is displayed as a character string.

[Measurement waveform]
The measurement waveform (an example of a symbol) displayed in the waveform area AR12 of the measurement result screen will be described with reference to FIGS.

4 shows a clot waveform (clotting reaction curve: an example of a first line figure) as a measured waveform displayed in the waveform area AR12. The clot waveform in the figure is a waveform represented by a line (an example of a first line) formed as a locus obtained by plotting measured values obtained by measuring the amount of scattered light of light irradiated onto a sample at measurement time intervals (e.g., approximately 0.1 seconds) over time.
The clot waveform may be a waveform represented by a line (an example of a first line) formed as a locus of plotting the measured value (vertical axis) for each measurement point (horizontal axis). The number of measurement points (i) is, for example, if the measurement time is every 0.1 seconds, the number of measurement points is represented by the time from the start of measurement = 0.1 × i. In this case, i may be 1, 2, 3, ... (increasing by 1) or i may be 5, 10, 15, ... (increasing by 5), and the increment may be set arbitrarily.

In FIG. 4, a line L1 is shown which corresponds to the case where the specimen is normal, and lines L2 and L3 are shown which correspond to the case where the specimen is not normal.
When the sample is normal, the clot waveform exhibits a sigmoid shape like line L1. On the other hand, when the sample is abnormal or the initial reaction is abnormal, the waveform exhibits a different shape from line L1. Lines L2 and L3 in the figure indicate abnormal conditions in which the clotting time is delayed compared to line L1.
The clotting time is the time it takes for a sample to clot due to the clotting reaction. The clotting time may be measured, for example, as the time it takes for the amount of scattered light to reach a predetermined ratio relative to the amount of scattered light determined as the end point of clotting.

Figure 5 shows an example of a clot waveform that focuses on early reaction abnormalities. Of the lines L31, L32, and L33 shown in the figure, line L31 does not indicate an early reaction abnormality, while lines L32 and L33 indicate an early reaction abnormality.

In addition, the measurement waveform displayed in the waveform area AR12 may be a waveform (differentiated waveform: an example of a third line figure) based on a line (an example of a third line) representing a differentiated value of the coagulation waveform as shown in Figure 6.
6 shows an example of a differential waveform as a measured waveform. The differential waveform in this figure is a waveform obtained by first-order differentiation of the clot waveform. The order of differentiation of the differential waveform as a measured waveform is not particularly limited, and the differential waveform may be obtained by second-order or third-order differentiation of the clot waveform.
In FIG. 6, a line L11 corresponding to the case where the sample is normal, and lines L12 and L13 corresponding to the case where the sample is not normal are shown.
If the specimen is normal, the differential waveform will rise at a standard time, as shown by line L11. On the other hand, if the specimen is abnormal, the waveform will rise, as shown by line L12, but the rise time will be delayed and the waveform peak will be gentle. Furthermore, line L13 will have a delayed rise and two peaks.

Furthermore, the measurement waveform displayed in the waveform area AR12 may be a waveform (corrected waveform: an example of a fourth line figure) based on a line (an example of a fourth line) that has been corrected to normalize so that the minimum and maximum values of the scattered light intensity (an example of a matching criterion) corresponding to the vertical axis of the coagulation waveform as shown in Figure 4 are equal (match).
7 shows an example of a corrected waveform as a measured waveform. In the figure, lines L21, L22, and L23 are shown as corrected waveforms. Lines L21, L22, and L23 are corrected waveforms obtained by correcting lines L1, L2, and L3 of the coagulation waveform in FIG. 4, respectively.

The form of the corrected waveform is not limited to the normalized waveform shown in FIG. 7, in which the maximum values of the scattered light amounts corresponding to the vertical axis of the coagulation waveform are equal.
As another example, the clot waveforms may be corrected to align the rising edge times (an example of a matching criterion). In this case, normalization may be performed to align the maximum values of the scattered light intensity corresponding to the vertical axis of the clot waveform, as shown in Figure 7.
Alternatively, the time when the amount of scattered light reaches a predetermined height may be used as a reference point, and the clot waveform may be corrected to align on the time axis so that this reference point coincides. The "predetermined height" may be, for example, the amount of scattered light at the end point of coagulation, or half the amount of scattered light at the end point of coagulation. In this case, normalization may also be performed by equating the maximum values of the amount of scattered light corresponding to the vertical axis of the clot waveform, as shown in Figure 7.

The measured waveform's shape characteristics can be used as a reference for estimating the nature and degree of abnormality in the sample. For example, the measurement result may show that the clotting time is normal, but based on the shape of the measured waveform, findings and analysis results may indicate an abnormality.

The shape of the measured waveform reflects whether the specimen is normal or abnormal. Below are examples of measured waveforms corresponding to abnormal cases.
Referring to Figure 8, we will explain a case where a normal clotting time is judged to be abnormal based on other factors. Figure 8(A) shows a clot waveform corresponding to a normal sample. On the other hand, the clot waveform in Figure 8(B) shows an abnormal state in which the clotting time is normal but the initial reaction is large in the area surrounded by the characteristic indicator frame FL. Furthermore, the clot waveform in Figure 8(C) shows an abnormal state in which the clotting time is normal but the waveform rises earlier than normal after the start of measurement, as shown in the area surrounded by the characteristic indicator frame FL.

On the other hand, there are cases where the clotting time itself is abnormal. Figures 9(A), 9(B), and 9(C) each show examples of clot waveforms where the clotting time is abnormal. The clot waveform in Figure 9(A) has a sigmoid shape, but the rise time is slow. Figure 9(B) shows an example where the rise time of the waveform is slow and the sigmoid shape is not obtained. Figure 9(C), as shown in the area surrounded by the feature indication frame FL, shows an example where the clotting reaction is still in progress at the time when the end point of clotting would normally be reached.

Also, with reference to FIG. 10, a case will be described in which the measured waveform as a differential waveform is determined to be abnormal due to other factors even if the clotting time is normal.
FIG. 10A shows an example of a differential waveform corresponding to a normal specimen for comparison.
Figure 10(B) shows an example where an abnormality is indicated by two peaks (bimodal) in the differentiated waveform. A normal differentiated waveform has a single peak, as shown in Figure 10(A).
FIG. 10C shows an example in which an abnormality is indicated by a small peak appearing before the main waveform peak, as shown in the area surrounded by the feature indicating frame FL.

11(A), 11(B), and 11(C) show examples of differential waveforms corresponding to abnormalities in clotting time.
FIG. 11A shows an example in which the differential waveform itself is close to normal, but the rise time is slower than normal, indicating an abnormality.
FIG. 11(B) is an example in which an abnormality is indicated by a delayed rise in the differentiated waveform and a gentler slope of the waveform after the peak, as shown in the area surrounded by the feature indication frame FL.
FIG. 11C shows an example in which an abnormality is indicated by the peak of the differential waveform being not steep and being highly flat, as shown in the area surrounded by the feature indicating frame FL.

As can be understood from the above description, each measurement item area on the measurement result screen displays a measurement value area AR11 showing the measurement value and a waveform area AR12 showing the measurement waveform. In this case, the user can check the numerical measurement values and measurement waveforms on the measurement result screen, which is a list of the measurement results for the sample. That is, in this embodiment, the measurement results for each sample are appropriately presented on the measurement result screen. Therefore, the user can accurately understand the measurement results from the numerical values and waveforms, without having to perform an operation such as switching to a screen presenting more detailed information.
As a result, the user can determine with a certain degree of confidence whether the sample is normal or abnormal and estimate the cause of the abnormality, simply by looking at the measurement result screen as a list of the measurement results, without having to perform an operation to switch to a screen that presents detailed information about the measurement results.
Furthermore, the measurement result screen simultaneously displays, for each measurement item, measurement values that are expressed as specific numerical values and measurement waveforms that allow the user to intuitively grasp the measurement results. This type of display increases the likelihood that the user will be able to quickly recognize the degree, severity, urgency, etc. of any abnormality.
In addition, for example, there may be cases where the measured values are within the normal range but the measured waveform indicates an abnormality. In such cases, the user is more likely to notice the abnormality by checking not only the measured values but also the measured waveform on the same screen.
If the user notices an abnormality on the measurement result screen, the user can check the measurement waveform in more detail as necessary, or request a retest of the sample.

In this embodiment, the measurement waveforms displayed in the waveform area AR12 for each measurement item on the measurement result screen include, as types, a clot waveform, a differential waveform, and a corrected waveform. The measurement waveform displayed in the waveform area AR12 may be any of a clot waveform, a differential waveform, and a corrected waveform.
In this case, the type of measurement waveform to be displayed in the waveform area AR12 may be selectable, for example, in response to a user operation. For example, the user may be able to set the measurement waveform to be displayed in the waveform area AR12 by default when the measurement result screen is initially displayed.

Furthermore, in this embodiment, when the measurement result screen is displayed, the measurement waveform displayed in the waveform area AR12 may be switchable in response to a user operation. In this case, the measurement waveform may be switchable uniformly for all waveform areas AR12 on the measurement result screen. Furthermore, the measurement waveform may be switchable on a specimen-by-specimen basis (in specimen unit area AR1 units). Furthermore, the measurement waveform may be switchable on a measurement item-by-measurement item basis for all specimens. Furthermore, the measurement waveform may be switchable for a measurement item of a specified specimen in response to a user operation.

In addition, in this embodiment, a feature indication frame FL (an example of a feature indication section) indicating a characteristic portion in some of the measurement waveforms in Figures 8 to 11 may be displayed as appropriate by being added to the measurement waveform in the waveform area AR12 on the measurement result screen.
Furthermore, the feature indication frame FL may be configured to be switchable between display and non-display in response to a predetermined operation by the user.
Furthermore, the aspect of the characteristic indication frame FL may change depending on the level of the characteristic of the response, such as, for example, an initial reaction, etc. For example, depending on the level of the characteristic, the frame portions of the characteristic indication frame FL may change so that multiple frames are displayed overlapping each other, the color or thickness of the frame portions may change, or the color inside the frame portions may change.

3, one measurement waveform is displayed in the waveform area AR12 corresponding to one measurement item. However, for example, multiple measurement waveforms of different types (e.g., coagulation waveform, differential waveform, corrected waveform) corresponding to the same measurement result may be displayed in the waveform area AR12.
In addition, the number of types of measurement waveforms displayed in the waveform area AR12 may be changeable in response to a user operation.

In addition, in this embodiment, when a predetermined operation, such as a click operation or a tap operation, is performed on one waveform area AR12, the measurement waveform displayed in the operated waveform area AR12 may be enlarged.
For example, the coordinate scale values may be omitted for the measurement waveform in waveform area AR12, and the coordinate scale values may be displayed for the enlarged measurement waveform. Also, if a feature indication frame FL is placed on the measurement waveform in waveform area AR12, the feature indication frame FL may be maintained in the enlarged measurement waveform as well.
Furthermore, even when one predetermined type of measured waveform is displayed in the waveform area AR12, multiple types of measured waveforms may be displayed depending on the enlargement.

[Example of processing procedure]
An example of a processing procedure that the blood coagulation test apparatus 100 of this embodiment executes in response to the display of the measurement result screen in the manner exemplified in FIG. 3 will be described with reference to the flowchart of FIG.

Step S100: In the blood coagulation test apparatus 100, the display control unit 122 accepts the generation of a display trigger that instructs the display of a measurement result screen. The display trigger may be generated, for example, in response to a user operation instructing the display of a measurement result screen. The display trigger may also be generated in response to the measurement unit 101 completing measurement of a predetermined group of samples.

Step S102: The display control unit 122 selects one sample (target sample) from the samples displayed on the measurement result screen to be used for generating a standard waveform.

Step S104: The display control unit 122 acquires the measurement result information associated with the sample ID of the target sample selected in step S102 from the measurement result information storage unit 131.

Step S106: The display control unit 122 generates a measurement waveform to be displayed in the waveform area AR12 using the measurement result information acquired in step S104. Specifically, in correspondence with Fig. 3, the display control unit 122 may generate a coagulation waveform as the measurement waveform.
In addition, in step S106, the display control unit 122 may generate a coagulation waveform, a differential waveform, and a corrected waveform as the measurement waveforms.
The generated measurement waveform may be associated with the specimen and the measurement item and stored in the storage unit 103. By storing the measurement waveform in this way, when displaying the measurement result screen from the second time onwards, it is only necessary to acquire the stored measurement waveform in step S106, and it is not necessary to generate a measurement waveform.

Step S108: The display control unit 122 determines whether measurement waveform generation has been completed for all samples currently being displayed on the measurement result screen. If there are still samples for which measurement waveform generation has not been completed, processing returns to step S102, and measurement waveform generation is performed for the next sample.

Step S110: When measurement waveform generation for all samples is completed in step S108, the display control unit 122 generates a measurement result screen and displays the generated measurement result screen.

When the measurement result screen is displayed and an operation is performed to instruct enlargement of the measurement waveform displayed in the waveform area AR12, the display control unit 122 displays an enlarged image of the target measurement waveform. The display control unit 122 may display the enlarged image of the measurement waveform, for example, as a pop-up window superimposed on the measurement result screen.
Furthermore, in response to an operation to instruct a change in the type of the measured waveform displayed in the waveform area AR12, the display control unit 122 controls so that the measured waveform of the new type is displayed. At this time, for example, when an instruction is given to change from a coagulation waveform to a differential waveform or a corrected waveform, if the differential waveform or corrected waveform has not yet been generated, the display control unit 122 may generate the differential waveform or corrected waveform from the coagulation waveform and switch to displaying the generated differential waveform or corrected waveform.
In addition, when displaying multiple types of measurement waveforms on a measurement result screen or a screen showing an enlarged measurement waveform, the display control unit 122 may generate a coagulation waveform, then generate a differential waveform and a correction waveform from the coagulation waveform, and display the generated coagulation waveform, differential waveform, and correction waveform.

Second Embodiment
[About simple waveforms]
Next, a second embodiment will be described. In the first embodiment, the line diagram as the measured waveform displayed in the waveform area AR12 was a clot waveform formed by plotting measured values on a coordinate system, a differentiated waveform of the clot waveform, or a corrected waveform obtained by correcting the amount of scattered light from the clot waveform. In other words, in the first embodiment, the line diagram as the measured waveform displayed in the waveform area AR12 was a waveform (standard waveform) that faithfully reflected the measured values.
In contrast, in the waveform area AR12 of this embodiment, instead of the above-mentioned standard waveform, a line diagram (simplified waveform: an example of a third line diagram) is displayed using a line (an example of a second line) that is a simplified version of the standard waveform. In this embodiment, simplification of the standard waveform may be, for example, processing that emphasizes and represents parts of the standard waveform that are considered to be characteristic and attract attention, and simplifies or omits parts that attract less attention.

FIGS. 13(A) to 13(H) show examples of simplified waveforms displayed in the waveform area AR12 of this embodiment. The simplified waveforms shown in FIG. 13(A) to 13(H) each show a shape pattern corresponding to a standard waveform indicating a certain abnormal state.

Figures 13(A) and 13(B) are simplified waveforms obtained by simplifying the shapes of different clot waveforms. Figure 13(A) is a simplified version of a non-sigmoid clot waveform. Figure 13(B) is a simplified version of a clot waveform with a gentler slope than normal due to an extended clotting time.

13(C) to 13(H) show simplified waveforms obtained by simplifying the shapes of different differential waveforms.
The simplified waveform in FIG. 13C is a simplified derivative waveform having a rise that is steeper than normal.
The simplified waveform in FIG. 13(D) is a simplified derivative waveform having a peak width wider than normal.
The simplified waveform of FIG. 13(E) is a simplified version of a differential waveform having a bimodal shape.
The simplified waveform in FIG. 13(F) is a simplified derivative waveform that is symmetrical about the peak timing.
The simplified waveform of FIG. 13(G) is a simplified derivative waveform in which the width after the peak is wider than before the peak.
The simplified waveform of FIG. 13(H) is a simplified derivative waveform in which the width after the peak is wider than the width before the peak as compared with FIG. 13(G).

The standard waveform is highly reliable in that it faithfully reflects the measured value. However, the waveform area AR12 does not occupy much space on the measurement result screen. For this reason, if the standard waveform is displayed in the waveform area AR12, it may be difficult for the user to grasp, for example, the characteristics corresponding to an abnormality.
Therefore, as in this embodiment, if a simplified waveform is displayed in the waveform area AR12 so as to represent the characteristic portions, the user can easily grasp the characteristics of the measured waveform.

[Configuration example for simple waveform display]
The blood coagulation test apparatus 100 of this embodiment may be provided with a simple waveform data storage unit 132 (FIG. 1) to display the simple waveform in the waveform area AR12.
The simplified waveform data storage unit 132 stores simplified waveforms corresponding to each typical pattern of possible standard waveform shapes. The simplified waveform data storage unit 132 may store multiple simplified waveform data corresponding to one typical pattern. In this case, the multiple simplified waveform data may be simplified so as to represent each of multiple characteristic parts indicated by the corresponding typical pattern.

In this embodiment, the display control unit 122 of the blood coagulation test apparatus 100 generates a corresponding standard waveform when displaying a simplified waveform in the waveform area AR12 of the measurement result screen. The display control unit 122 acquires corresponding measurement values from the measurement result information storage unit 131 and generates a clot waveform by plotting the acquired measurement values on a coordinate system. The display control unit 122, for example, determines the typical pattern of the generated clot waveform. The display control unit 122 acquires simple waveform data associated with the determined typical pattern from the simple waveform data storage unit 132. The display control unit 122 displays a line diagram as a simplified waveform drawn based on the acquired simple waveform data in the corresponding waveform area AR12.

Furthermore, when displaying a simplified waveform based on a differentiated waveform or a corrected waveform in the waveform area AR12, the display control unit 122 generates a differentiated waveform or a corrected waveform from the clot waveform generated as described above, and determines a typical pattern of the generated differentiated waveform or corrected waveform. The display control unit 122 acquires simplified waveform data associated with the determined typical pattern from the simplified waveform data storage unit 132, and displays a line figure as a simplified waveform drawn based on the acquired simplified waveform data in the corresponding waveform area AR12.
The display control unit 122 may perform pattern matching to determine the typical pattern of the generated standard waveforms (clotting waveform, differential waveform, corrected waveform). In addition, for pattern matching, the display control unit 122 may use a trained model that has been trained to estimate a typical pattern in response to an input of the shape of the standard waveform.

In addition, if the size of the waveform area AR12 on the measurement result screen can be made relatively large, for example because the screen size of the display unit 105 is large, the simplified waveforms PW (PW-1, PW-2) may be arranged in the waveform area AR12 so as to be superimposed on the standard waveform, as illustrated in Figure 14.
In the figure, the standard waveform is a differentiated waveform, and has two characteristics: it is bimodal and the width after the peak is wider than before the peak. In this case, an example is given showing two simplified waveforms: a simplified waveform PW-1 that shows bimodal characteristics and a simplified waveform PW-2 that has a wider width after the peak than before.
In other words, the two simplified waveforms PW-1 and PW-2 are obtained by dividing a single original differential waveform into two line components for each of the two features, based on the two features that the original differential waveform has.

Note that this method of dividing and presenting (displaying) a waveform according to multiple shape characteristics is not limited to simple waveforms, and may also be performed on standard waveforms, for example.

Furthermore, for example, when a simplified waveform is displayed in the waveform area AR12 and then an operation to enlarge the waveform area AR12 is performed, the corresponding standard waveform may be enlarged and displayed instead of the simplified waveform.
Furthermore, for example, when a simplified waveform (a simplified waveform divided into multiple parts may be displayed) or a standard waveform is displayed in the waveform area AR12, and an operation to enlarge the waveform area AR12 is performed, one or more simplified waveforms PW may be displayed together with the enlarged standard waveform, as in the manner shown in Figure 14.
Furthermore, for example, when a simplified waveform (which may be divided into multiple parts) is displayed in the waveform area AR12 and an operation to enlarge the waveform area AR12 is performed, an explanation of the simplified waveform may be displayed. The explanation of the simplified waveform may be, for example, an explanation of the characteristic parts of the simplified waveform, an explanation of whether or not there is an abnormality, and if there is an abnormality, a specific explanation of the abnormality.
In addition, in the waveform area AR12, the display of two or more predetermined waveforms from among the simplified waveform and the standard waveform (clotting waveform, differential waveform, corrected waveform) may be switchable in response to an operation.

Furthermore, detailed information regarding the analysis flag may be displayed in response to a specified operation being performed on the flag area AR14.

Furthermore, the display unit 105 may be capable of displaying a search screen presenting a list of simple waveforms stored in advance in the simple waveform data storage unit 132. Specifically, the list of simple waveforms on the search screen may be, for example, a list of simple waveforms arranged side by side, such as those shown in Figures 13(A) to 13(H). In addition, each simple waveform arranged on the search screen may be accompanied by a comment explaining the characteristics of the waveform.
The user can select at least one of the simplified waveforms arranged on the search screen and perform an operation to instruct execution of a search (search instruction operation). In response to the search instruction operation, a search result screen may be displayed on the display unit 105, which presents a list of samples having standard waveforms corresponding to the same simplified waveform selected on the search screen as search results.
On the search result screen, for each list item of samples, the measurement results may be presented in a predetermined format, for example, together with the sample ID. In this case, for example, the measurement results may include a measured value including the clotting time and a standard waveform. Alternatively, the measurement results may include the clotting time, the standard waveform, and a simplified waveform. Alternatively, the measurement results may include the standard waveform and the simplified waveform. Alternatively, the measurement results may include the standard waveform without the simplified waveform.
Such a search function allows the user to search for specimens according to the type of abnormality that corresponds to the characteristics of the simplified waveform.

<Modification>
Modifications of the above embodiments will be described below.
[First Modification]
The blood coagulation test apparatus 100 of this modified example may include an additional item estimation unit 123 ( FIG. 1 ) that estimates additional items related to the medical treatment of the sample in the control unit 102. The additional item estimation unit 123 of this modified example estimates a disease of the sample as an additional item related to the medical treatment of the sample.

15A and 15B show examples of the relationship between the shape of the standard waveform and diseases, in which Fig. 15A shows a clot waveform corresponding to a normal state and a differential waveform for comparison.
15(B) shows the clot waveform and differential waveform corresponding to hemophilia A (factor VIII deficiency). In the case of hemophilia A (factor VIII deficiency), the clot waveform has a slower rise time and a gentler slope than normal. Furthermore, as shown by the characteristic indicator frame FL, the differential waveform is highly flat and bimodal, but there is no significant difference in height between the primary peak (the earlier of the two peaks) and the secondary peak (the later of the two peaks).
15(C) shows the clot waveform and differential waveform corresponding to hemophilia B (factor IX deficiency). In the case of hemophilia B (factor IX deficiency), the clot waveform has a slower rise time and a gentler slope than normal. Furthermore, as shown by the characteristic indicator frame FL, the differential waveform has a highly flattened shape with a bimodal shape in which the secondary peak is significantly higher than the primary peak.
15(D) shows the clot waveform and differential waveform corresponding to LA. In the case of LA, the clot waveform has a shape that rises slower than normal. The differential waveform has a high degree of flatness and a gentle shape near the peak, as shown by the characteristic indication frame FL.
Figure 15(E) shows the clot waveform and differential waveform corresponding to factor II deficiency. In the case of factor II deficiency, the clot waveform rises slightly slower than normal and has a slightly gentler shape than normal. The differential waveform has a long tail after the peak, as shown by the characteristic indicator frame FL.

The additional item estimation unit 123 can estimate the disease of the specimen based on the shape of the measurement waveform that is characteristic of the disease as described above. The additional item estimation unit 123 may, for example, categorize (classify) the shape of the measurement waveform and identify the disease corresponding to the categorized measurement waveform.
In this case, the blood coagulation test apparatus 100 may store disease waveform correspondence data in which a type pattern of the shape of the measured waveform is associated with each disease in the storage unit 103. In this case, the additional item estimation unit 123 may identify the disease associated with the identified type of the measured waveform from the disease waveform correspondence data. Furthermore, the additional item estimation unit 123 may estimate the disease corresponding to the shape of the measured waveform, for example, by using a trained model that has been trained to estimate the corresponding disease in response to an input of the measured waveform.

The display control unit 122 may display information about the estimated disease on the measurement result screen. There are no particular limitations on the location where the information about the disease is displayed on the measurement result screen, but as an example, it may be displayed in the flag area AR14 as an element of the analysis flag. In this case, since the flag area AR14 is provided corresponding to each measurement item, the measurement result screen can display each estimated disease individually according to the measurement results for each measurement item.

[Second Modification]
The additional item estimation unit 123 of this modified example may estimate drug administration as an additional item related to the medical treatment of the specimen.

16A and 16B show examples of the relationship between the shape of the standard waveform and drug administration, with Fig. 16A showing a normal clot waveform and a differential waveform for comparison.
16(B) shows the clot waveform and the differential waveform corresponding to the administration of DOAC (direct oral anticoagulant). In the case of DOAC administration, the clot waveform has a delayed onset compared to normal. As shown by the characteristic indication frame FL, the differential waveform has a shape in which the onset of the waveform is delayed but the angle after the onset is steep.
16(C) shows the clot waveform and differential waveform corresponding to heparin administration. In the case of heparin administration, the clot waveform has a slow rise time, a gradual rise, and a gradual curve as it reaches its maximum value. The differential waveform has a highly symmetrical shape around the peak, as shown by the characteristic indicator frame FL.
16(D) shows the clot waveform and differential waveform corresponding to the administration of argatroban. When argatroban is administered, the clot waveform becomes non-sigmoidal. The differential waveform has a small peak level and gradually decays after the peak.
Note that drug administration that can be estimated from the measured waveforms (clotting waveform, differential waveform) is not limited to the examples shown in Figures 16(B), 16(C), and 16(D) above, and includes, for example, emicizumab.

The additional item estimation unit 123 can estimate the drug administration for the sample based on the shape of the measurement waveform that is characteristic of drug administration. Specifically, the additional item estimation unit 123 can estimate the presence (necessity) of drug administration to the patient corresponding to the sample and the concentration of the administered drug, as the estimation related to drug administration based on the sample, and the estimation result can be used to consider appropriate drug administration for treatment.
In this modified example, the additional item estimation unit 123 may also be configured to categorize (classify) the shape of the measured waveform, as in the first modified example, and identify the drug administration corresponding to the categorized measured waveform.
In this case, the blood coagulation test apparatus 100 may store drug administration waveform correspondence data in the storage unit 103, which associates a typical pattern of the shape of the measured waveform with each drug administration content. In this case, the additional item estimation unit 123 may identify the drug administration associated with the identified type of measured waveform from the drug administration waveform correspondence data. Furthermore, the additional item estimation unit 123 may estimate the drug administration corresponding to the shape of the measured waveform, for example, by using a trained model that has been trained to estimate the corresponding drug administration in response to an input of the measured waveform.

The additional item estimation unit 123 may also estimate treatment methods other than drug administration based on the shape of the measured waveform, or other necessary test items, as additional items. The display control unit 122 may display information such as the estimated treatment method or test items on the measurement result screen, or may display it in a pop-up window or the like in response to an operation on the measurement result screen.

[Third Modification]
The display configuration of the measurement result screen described above may also be applied to tests other than blood coagulation tests. Tests other than blood coagulation tests are not particularly limited, but one example is colorimetric analysis (absorbance analysis).

Figure 17 shows the measurement results of a sample by colorimetric analysis. Curves L41 and L42 in the figure were formed by plotting the measured values of absorbance (vertical axis) for each photometric point (horizontal axis). Curve L41 corresponds to the prozone state, and curve L42 corresponds to the nonspecific agglutination state.

For example, the curve shown in Figure 17 may be displayed for each specimen unit area on the colorimetric analysis measurement result screen. Also, in this modified example, as in the second embodiment, a simplified curve that is a simplification of the curve shown in Figure 17 may be displayed.

[Fourth Modification]
In addition, the blood coagulation testing device 100 may be configured to function by distributing the functions among multiple devices, each of which is given a specific function, and then connecting them to each other so that they can communicate with each other and work together to execute processing.

Here, "loading a program recorded on a recording medium into a computer system and executing it" includes installing the program on a computer system. The term "computer system" here includes hardware such as an OS and peripheral devices. The term "computer system" may also include multiple computer devices connected via a network, including communication lines such as the Internet, WAN, LAN, and dedicated lines.

The program may be divided into multiple parts, each downloaded at a different time and then combined on the terminal device, or each part may be distributed by a different distribution server. Furthermore, the term "computer-readable recording medium" also includes a storage medium that stores a program for a certain period of time, such as volatile memory (RAM) within a computer system that acts as a server or client when a program is transmitted over a network.
