[0011] [Overview] The following describes an information presentation device, an information presentation method, and a program according to this embodiment, using an analytical device as an example. The analytical device according to this embodiment is a device that collects a sample to be analyzed from a container in which the sample is sealed, and analyzes the collected sample. The analytical device according to this embodiment collects (samples) the sample from the container using a sample probe (hereinafter simply referred to as a probe).

[0012] The analytical device of this embodiment is configured to obtain an image (collection status image) of the container selected for collection by a camera during each unit collection period in which a sample is collected from a container placed at a collection position. Furthermore, the analytical device of this embodiment determines whether or not a collection-related error (collection error (sampling error)) has occurred each time a sample is collected from the container. A collection error is an example of an abnormality that occurs in response to sample collection.

[0013] Furthermore, the analytical device of this embodiment is capable of presenting information about the sampling error in response to a sample sampling in which a sampling error has been determined to have occurred. The information about the sampling error is presented, for example, by display on a display unit of the analytical device or on a terminal communicably connected to the analytical device. Furthermore, in this embodiment, when presenting the information about the sampling error by display, a sampling status image obtained by capturing an image during the sampling of the corresponding sample is included in the display.

[0014] [Example of Functional Configuration of Analytical Apparatus] Fig. 1 shows an example of the functional configuration of an analytical apparatus 100 according to this embodiment. The analytical apparatus 100 may be configured to include, as hardware, a central processing unit (CPU), read-only memory (ROM), random access memory (RAM), and storage devices such as hard disk drives (HDDs) and solid state drives (SSDs). The functions of the analytical apparatus 100 shown in the figure are realized by the CPU included in the analytical apparatus 100 executing a program. The analytical apparatus 100 shown in the figure includes a measurement unit 101, a camera 102 (an example of an imaging unit), a control unit 103, a storage unit 104, an operation unit 105, a display unit 106, and a communication unit 107.

[0015] The measurement unit 101 is a part where sample measurements are performed. The measurement unit 101 stores containers containing samples, sequentially collects samples from the stored containers, and dispenses the collected samples into containers for testing, thereby collecting the dispensed samples as measurement targets. The measurement unit 101 performs measurements on the collected samples. When collecting a sample from a container in the measurement unit 101, a probe is inserted into the container and the sample is aspirated from the probe.

[0016] The camera 102 is provided so as to be able to capture images of the container placed at the collection position in the measurement unit 101 from the side. The camera 102 captures images at a predetermined timing for each unit collection period, for example, under the control of the control unit 103. The captured images captured by the camera 102 are acquired by the information acquisition unit 131 of the control unit 103 as collection status images. The collection status images are treated as images showing the status when a sample is being collected by the probe during the corresponding unit collection period.

[0017] FIG. 2 shows the positional relationship between the container 300 placed at the sampling position SP of the measurement unit 101 and the camera 102. This figure shows a situation in which the probe 200 is inserted into the container 300 from above to aspirate the sample. This figure shows an example in which the sample placed in the container 300 is centrifuged blood. In this case, the blood sample placed in the container 300 is separated into three layers from top to bottom: plasma in the first layer LY1, buffy coat in the second layer LY2, and blood cells in the third layer LY3. In this case, the sample is sampled from the plasma in the first layer LY1. Therefore, when aspirating the sample, the position of the tip of the probe 200 in the vertical direction is adjusted so that it is located within the first layer LY1. Hereinafter, a case will be described in which the plasma in the first layer LY1 is sampled as the measurement target from the container 300 containing the blood sample as shown in FIG. 2 .

[0018] The camera 102 is provided, for example, to capture an image of the entire container 300 placed at the collection position SP from the side. In this case, it is preferable to set the positional relationship between the container 300 and the camera 102 so that, for example, a vertical line passing through the center of the container 300 in the left-right direction coincides with the optical axis of the lens of the camera 102.

[0019] Returning to FIG. 1 for the explanation, the measurement unit 101 includes a sensor unit 111. The sensor unit 111 includes one or more sensors each configured to detect a predetermined event corresponding to the determination of a sampling error. The sensor unit 111 may include a pressure sensor. The pressure sensor detects the pressure in the hollow portion of the probe 200. The hollow portion of the probe 200 is the portion through which the sample aspirated for sampling passes. The sensor unit 111 may also include a capacitance sensor. Depending on the capacitance sensor, it can detect whether or not the tip of the probe 200 is in contact with the liquid serving as the sample in the container 300 to be sampled.

[0020] The control unit 103 executes various controls in the analysis device 100. Specifically, the control unit 103 controls the measurement operation of the measurement unit 101. The control unit 103 also controls so that information regarding collection errors is presented.

[0021] The control unit 103 includes an information acquisition unit 131 (an example of an image acquisition unit), a determination unit 132, an information presentation unit 133, and a measurement operation control unit 134 as functional units that handle presentation of information related to collection errors.

[0022] The information acquisition unit 131 acquires collection process result information output by the measurement unit 101 corresponding to each unit collection period. The collection process result information is information indicating the status of operation of the measurement unit 101 during the corresponding unit collection period, and may include, for example, detection information output during the corresponding unit collection period by a sensor included in the sensor unit 111. The information acquisition unit 131 also acquires collection status images captured by the camera 102 during each unit collection period. The information acquisition unit 131 stores collection status information including the collection process result information and collection status images acquired for each unit collection period in the collection status information storage unit 141.

[0023] The determination unit 132 makes a determination regarding a collection error for each unit collection period based on collection status information obtained for each unit collection period.

[0024] The information presenting unit 133 presents information about the sampling error in response to the determination unit 132 determining that a sampling error has occurred in the sample sampling performed during the unit sampling period. Specifically, the information presenting unit 133 may display the information about the sampling error on the display unit 106. Furthermore, the information presenting unit 133 may transmit the information about the sampling error to a user terminal used by a user, such as an operator of the analysis device 100, so that the information about the sampling error is presented to the user on the user terminal.

[0025] The measurement operation control unit 134 mainly controls the operation of hardware such as mechanisms in the measurement unit 101 so that measurement is performed in the measurement unit 101 .

[0026] The storage unit 104 stores various types of information corresponding to the analysis device 100. The storage unit 104 includes a collection status information storage unit 141. The collection status information storage unit 141 stores collection status information corresponding to each sample collection for one container 300.

[0027] The operation unit 105 includes various operators and input devices provided in the analysis apparatus 100. The operation unit 105 may also include an input device connected to the analysis apparatus 100. The operation unit 105 outputs operation signals corresponding to operations performed on the various operators and input devices to the control unit 103. The control unit 103 executes processing corresponding to the input operation signals.

[0028] The display unit 106 displays an image under the control of the control unit 103 .

[0029] The communication unit 107 communicates with other devices such as terminals via a network.

[0030] [Regarding Imaging Timing in Unit Collection Period] An example of the flow of operation of the measurement unit 101 and the timing of imaging by the camera 102 in a unit collection period corresponding to one sample collection from one container 300 will be described with reference to Figure 3. In the figure, the measurement unit 101 operates in the order of operation procedures HW1 to HW10.

[0031] Operation procedure HW1 shows a situation in which the container 300 to be sampled has not yet been moved to the sampling position SP in the measurement unit 101. Next, the container 300 to be sampled is moved to the sampling position SP from the situation in operation procedure HW1, resulting in a situation in which the container 300 to be sampled is positioned at the sampling position SP, as shown as operation procedure HW2.

[0032] A label identifying the sample to be measured is affixed to the container 300 to be sampled. Therefore, in the measurement unit 101, the container 300 to be sampled, which is placed at the sampling position SP as in operation procedure HW2, is rotated as shown in operation procedure HW3 so that the camera 102 does not capture an image of the label. Note that, for example, using a near-infrared camera for the camera 102 may enable imaging through the label. In this case, since there is no need to consider avoiding the label when capturing an image of the container 300 containing the sample to be measured, the rotation of the container 300 according to operation procedure HW2 may be omitted. However, in the following description, an example will be given in which the camera 102 is configured to capture images using normal visible light, not a near-infrared camera, and operation procedure HW2 is required.

[0033] After the target container 300 is rotated by operation procedure HW3, the camera 102 takes a first image of the target container 300 as shown in operation procedure HW4. As a result of the camera 102 taking the image, a first collection status image (first collection status image: an example of a first captured image) is obtained. The first collection status image shows the state of the sample in the container 300 without the probe 200 at a timing before collection is performed in the corresponding unit collection period.

[0034] The first collection status image can determine whether the sample contained in the collection target container 300 placed at the collection position SP is in a state where it can be measured. Therefore, the determination unit 132 may determine whether the sample is in a state where it can be measured based on the first collection status image. If the determination unit 132 determines that the sample is in a state where it cannot be measured, the control unit 103 may return the corresponding container 300 to its original storage position, for example, without collecting a sample, as a measurement impossible error. The measurement impossible error corresponds to whether or not it is possible to collect a sample, and therefore may be included in one type of collection error in this embodiment.

[0035] After the first collection status image is captured, the measurement unit 101 lowers the probe 200 and inserts it into the container 300 from which the sample is to be collected, as shown as operation procedure HW5, so that the tip of the probe 200 is immersed to a predetermined depth in the first layer LY1 of the sample in the container 300 from which the sample is to be collected.

[0036] In response to the tip of the probe 200 being immersed in the sample in the container 300 to be sampled as in operation procedure HW5, the camera 102 captures an image for the second time as shown in operation procedure HW6, thereby obtaining a second sample-taking status image (second sample-taking status image: an example of a second captured image). The second sample-taking status image shows the state in which the tip of the probe 200 is immersed in the sample in the container 300 at a timing before sample collection is performed in the corresponding unit sample-collection period.

[0037] After the second collection situation image is captured in the operational procedure HW6, the measurement unit 101 causes the probe 200 to aspirate a predetermined amount of sample, as shown in the operational procedure HW7.

[0038] After the suction of the sample by operation procedure HW7 is completed, as shown in operation procedure HW8, the camera 102 takes a third image while the probe 200 remains immersed in the sample in the container 300 to be sampled, thereby obtaining a third collection status image (third collection status image: an example of a third captured image).

[0039] When the third imaging is completed by the operation procedure HW8, the probe 200 is then raised to a position outside the container 300 from which the sample is to be collected, as shown in operation procedure HW9.

[0040] When the probe 200 is moved outside the container 300 to be sampled by operation procedure HW9, the measurement unit 101 then moves the container 300 that had been the sampled object from the sampling position SP and returns it to a predetermined storage position, as shown in operation procedure HW10.

[0041] The measurement unit 101 may perform measurements of multiple measurement items for a single measurement target sample. In this case, the measurement unit 101 may perform multiple sample collections for the same container 300 for each unit collection period established for each of the multiple measurement items. Alternatively, the measurement unit 101 may perform multiple sample collections even when performing measurements of a single measurement item for a single measurement target sample (e.g., a calibrator). When performing multiple sample collections for a single container 300, the sample collection procedure for the first time is as follows: the first time, the operations according to the operational procedures HW1 to HW9 in FIG. 3 are performed; and from the second time onward, the operations according to the operational procedures HW4 to HW9 are repeated. Furthermore, in the final time, after the operations according to the operational procedures HW4 to HW9, the container 300 may be returned from the collection position SP to a predetermined storage position according to the operational procedure HW10. Furthermore, as described above, the first collection status image is used to determine whether the sample in the container 300 is ready for measurement. Based on this, when sampling multiple times from one container 300 in response to measurements of multiple measurement items corresponding to one measurement target sample, it is possible to adopt the idea that it is sufficient to obtain the first sampling status image only once at the beginning. Therefore, when measurements of multiple measurement items are performed corresponding to one measurement target sample, the first sampling status image before sampling according to operation procedure HW4 may be captured during the first sampling, and the capturing of the first sampling status image may be omitted from the second sampling onwards.

[0042] 3, during a unit collection period in which the measurement unit 101 and the camera 102 are operating, the determination unit 132 may be configured to make a determination regarding a collection error, for example, as follows. In the following explanation, an example will be given in which the sensor unit 111 is provided with a pressure sensor that detects the pressure inside the hollow portion of the probe 200 and a capacitance sensor that detects contact between the tip of the probe 200 and the liquid surface of the sample (liquid surface contact), and the determination unit 132 is configured to make a determination regarding a collection error based on the detection output of the pressure sensor.

[0043] The probe 200 is inserted into the container 300 by moving from top to bottom at the collection position, and the tip of the probe 200 contacts the liquid surface of the layer (first layer LY1) of the sample to be collected and further penetrates into the first layer LY1 so as to be immersed in the sample. The pressure sensor in the sensor unit 111 is configured to detect the pressure of a hollow portion formed in the probe 200. The hollow portion holds the sample aspirated from the container 300.

[0044] The measurement unit 101 releases air from the hollow portion of the probe 200 to the tip thereof while the probe 200 descends and contacts the liquid surface of the container 300 in response to the transition from operation procedure HW4 to operation procedure HW5 in FIG. 3 . At this time, the pressure sensor detects the pressure in the hollow portion. The pressure detected by the pressure sensor is a low value when the tip of the probe 200 is not in contact with the liquid surface of the sample, but increases significantly as the tip of the probe 200 contacts the liquid surface of the sample. Based on this change in pressure during the transition from operation procedure HW4 to operation procedure HW5, the determination unit 132, for example, determines whether the tip of the probe 200 has come into contact with the liquid surface. The determination unit 132 can also determine whether the tip of the probe 200 has come into contact with the liquid surface based on the detection output of a capacitance sensor.

[0045] Furthermore, when the probe 200 is sucking the sample as in operation procedure HW7 of FIG. 3, the pressure sensor detects the pressure generated as the sample fills the hollow portion by suction.

[0046] Furthermore, as shown by the transition from operation procedure HW8 to operation procedure HW9 in Figure 3, when the probe 200, which has completed suctioning the sample and is holding the sample in its hollow portion, rises and moves away from the container 300 from which the sample is to be collected, the change in capacitance detected by the capacitance sensor detects that the tip of the rising probe 200 has transitioned from a state in which it was immersed in the sample to a state in which it has left the liquid surface.

[0047] As described above, if the collection is performed normally based on the detection output of the sensor unit 111, the judgment unit 132 judges whether the tip of the descending probe 200 has come into contact with the liquid surface of the sample, or whether the tip of the ascending probe 200 has left the liquid surface of the sample.

[0048] Then, based on the detection output of the sensor unit 111, the judgment unit 132 can make a judgment regarding collection errors for each type of error, such as high-position liquid surface contact, abnormal sample amount, abnormal collection amount, probe clogging, and insufficient suction, for example, as follows.

[0049] High-level liquid contact is a sampling error caused by a false detection of liquid contact at a position higher than the actual liquid level. When the determination unit 132 detects, based on the detection output of the pressure sensor or capacitance sensor, that liquid contact has occurred at a position higher than the liquid level position of the sample that is assumed to be in the container 300, the determination unit 132 determines that a sampling error due to high-level liquid contact has occurred.

[0050] A sample amount abnormality is a collection error caused by detection of liquid surface contact at a position lower than the reference liquid level position because the amount of sample before collection in the container 300 is less than the reference amount. The determination unit 132 determines that a collection error as a sample amount abnormality has occurred when it detects, based on the detection output of the pressure sensor or capacitance sensor, that liquid surface contact has occurred at a position lower than the liquid level position of the sample that is set as being expected in the container 300.

[0051] A collection volume abnormality is a collection error caused by an inappropriate amount being aspirated when collecting a sample using the probe 200. When measuring multiple measurement items for a single sample, the measurement unit 101 collects samples from the same container 300 multiple times, one for each measurement item. When collecting samples multiple times from the same container 300 in this manner, the determination unit 132 stores the height position of the probe 200 when liquid contact is detected when collecting (aspirating) a sample for each measurement item. The determination unit 132 then compares the height position of the probe 200 when liquid contact is detected in the current sample collection with the previous height position of the probe 200. If the difference between the compared height positions does not correspond to a value corresponding to the appropriate amount of sample collected, the determination unit 132 determines that a collection error, i.e., a collection volume abnormality, has occurred.

[0052] Probe clogging is a collection error that occurs when, for example, probe 200 should only aspirate plasma, but instead aspirates a blood clot or the like, causing a blockage in the hollow part of probe 200 and preventing normal aspirating. If the pressure detected by the pressure sensor when probe 200 is aspirating a sample in accordance with operation procedure HW7 in Figure 3 deviates from the range of values ​​considered appropriate for aspirating a sample, determination unit 132 determines that a collection error due to probe clogging has occurred.

[0053] Insufficient suction is a collection error caused by improper suction due to the probe 200 separating from the liquid surface of the sample during suction. The determination unit 132 compares the first capacitance detected by the capacitance sensor when the probe 200 descends and contacts the liquid surface of the sample with the second capacitance detected by the capacitance sensor after suction of the sample is completed. If suction is performed normally without insufficient suction, the probe 200 remains in contact with the liquid surface of the sample, and the second capacitance after suction is equal to the first capacitance. For example, the determination unit 132 may determine that a collection error due to insufficient suction has occurred if, as a result of comparing the first capacitance and the second capacitance, the difference between the two is equal to or greater than a certain value.

[0054] [Collection Status Information] Figure 4 shows an example of collection status information stored in the collection status information storage unit 141 in accordance with the example operation procedure of Figure 3. The collection status information in Figure 4 corresponds to a case where sample collection has been performed for a single measurement target sample. The collection status information in Figure 4 corresponds to a case where a sample has been collected from the container 300 in one unit collection period in accordance with measuring one measurement item corresponding to one measurement target sample. The collection status information in Figure 4 includes fields for the sample ID, collection ID, measurement item, collection date and time, error information, and collection status image.

[0055] The sample ID field stores a sample ID that uniquely identifies the corresponding measurement target sample. In the case of a blood test, for example, the sample ID may be associated with the test subject.

[0056] The collection ID field stores a collection ID that uniquely identifies the corresponding sample collection.

[0057] The measurement item field stores information indicating the measurement item designated for the corresponding sample to be measured.

[0058] The collection date and time field stores the date and time when the sample serving as the corresponding measurement target sample was collected.

[0059] The error information field stores information indicating an error condition (error information). Specifically, the error information indicates whether an error has occurred regarding the collection of the corresponding measurement target sample, and if an error has occurred, the information may indicate the type of collection error (measurement impossible error, high liquid surface contact, abnormal collection amount, probe clogging, insufficient suction).

[0060] The collection status image fields store collection status images (first collection status image, second collection status image, third collection status image) captured by the camera 102 during the corresponding unit collection period. Note that the capture date and time of the corresponding capture may be added as metadata to each of the collection status images (first collection status image, second collection status image, third collection status image). Alternatively, although not specifically illustrated, the collection status information may include a field for storing the capture date and time for each collection status image.

[0061] The collection status image stored in the collection status information may be the same size and format as the original image captured by the camera 102, or may be an image obtained by reducing the size of the original image or converting it into a predetermined compressed format. When reducing the size of the original image, trimming may be performed to remove areas in the original image where the container 300 and the probe 200 do not exist.

[0062] As described above, multiple measurement items may be measured for a single measurement target sample. FIG. 5A shows collection status information for a case where sample collection is performed over multiple unit collection periods in response to the measurement of multiple measurement items for a single measurement target sample. Similarly to FIG. 4, the collection status information in FIG. 5A corresponds to a case where sample collection is performed for a single measurement target sample. Specifically, the collection status information in FIG. 5A corresponds to a case where sample collection is performed from the same single container 300 over three unit collection periods in response to the measurement of three measurement items for a single measurement target sample. The collection status information in FIG. 5A includes fields for sample ID, measurement item, collection date and time, error information, and collection status image.

[0063] 5A, fields corresponding to three measurement items (measurement item 1, measurement item 2, and measurement item 3) are provided as measurement items. Information indicating specific measurement items may be stored in each of the measurement item 1, measurement item 2, and measurement item 3 fields. In this case, the sample ID stored in the sample ID field is common to the three measurement items.

[0064] Furthermore, for the collection ID, measurement item, collection date and time, error information, and collection status image, three fields are provided corresponding to each of the three measurement items (measurement item 1, measurement item 2, measurement item 3).

[0065] Each field of the collection ID corresponding to each of the three measurement items stores a collection ID that is uniquely associated with each sample collection from the container 300 performed for use in measuring the corresponding measurement item.

[0066] Each collection date and time field corresponding to each of the three measurement items stores the date and time when the sample was collected from the container 300 to be used for measuring the corresponding measurement item. If samples for each measurement item are collected consecutively from the same container 300, a specified date and time within the period from the first to the final (third) sample collection may be used as the collection date and time common to the three measurement items.

[0067] Each field of the error information corresponding to each of the three measurement items stores error information indicating an error condition that occurred when a sample was taken from the container 300 for use in measuring the corresponding measurement item.

[0068] Three collection status image fields are provided for each of the three measurement items: a first collection status image, a second collection status image, and a third collection status image. In the figure, image file 11, image file 12, and image file 13 are stored in the fields for the first collection status image, the second collection status image, and the third collection status image corresponding to measurement item 1, respectively. Image file 12, image file 22, and image file 32 are stored in the fields for the first collection status image, the second collection status image, and the third collection status image corresponding to measurement item 2, respectively. Image file 13, image file 23, and image file 33 are stored in the fields for the first collection status image, the second collection status image, and the third collection status image corresponding to measurement item 3, respectively.

[0069] In the collection status information shown in FIG. 5A, a collection ID corresponding to each measurement item is associated with a common sample ID. In this collection status information format, the collection status images (first collection status image, second collection status image, and third collection status image) are each associated with an individual collection ID and a common sample ID. For example, if an error occurs when the first collection status image is acquired in operation procedure HW4 before a sample is collected, subsequent sample collection may not be performed, and a collection ID may not be assigned. In such a case, the first collection status image can be associated with a sample ID and managed without being associated with a collection ID.

[0070] Furthermore, as described above, when sampling from one container 300 multiple times in accordance with the measurement of multiple measurement items, the first sampling status image may be generated in the operation procedure for the first sampling and may be omitted in the operation procedures for the second and subsequent sampling. In this case, the sampling status information may have a structure in which the image file 12 stored as the first sampling status image corresponding to measurement item 2 and the image file 13 stored as the first sampling status image corresponding to measurement item 3 are not stored, as exemplified in FIG. 5(B).

[0071] [Example of Presentation of Error-Related Information] The analytical device 100 of this embodiment presents information (error-related information (an example of abnormality-related information)) relating to a sampling error that occurs during sample sampling performed by the measurement unit 101. The analytical device 100 may present the error-related information by displaying it on the display unit 106 provided in the analytical device 100. Furthermore, the analytical device 100 may transmit the error-related information to a user terminal or the like used by the user, thereby causing the error-related information to be presented on the user terminal or the like.

[0072] Furthermore, the error-related information may be presented, for example, after sample collection is completed. For example, the information presenting unit 133 of the analytical device 100 may use the collection status information stored in the collection status information storage unit 141 to display a list of collection status information for each sample collection that has been performed so far on the display unit 106 or a user terminal. The user performs an operation to select a list item indicating that a collection error has occurred from the displayed list of collection status information. The information presenting unit 133 may display the error-related information on the display unit 106 or a user terminal based on the collection status information corresponding to the selected list item.

[0073] 6 shows an example of how error-related information is presented on the display unit 106 or a user terminal, etc. In the figure, an example of presenting error-related information on an error-related information screen is shown.

[0074] The error-related information screen in Figure 6 displays the error content, indicating that a sampling error has occurred, and also displays details of the sampling error (error details), such as the measurement item corresponding to the corresponding sample sampling, the sampling date and time, the sampling ID, and the error type. The error type column also displays the corresponding error code.

[0075] Furthermore, the error-related information screen of FIG. 6 further includes image areas AR1, AR2, and AR3 that present collection status images captured by the camera 102 during the corresponding sample collection operation.

[0076] Image area AR1 is an area where a first collection status image is presented to indicate the state of the container 300 before the corresponding sample is collected (aspirated). As described above, multiple sample collections may be performed for multiple measurement items corresponding to a single measurement target sample, with the first collection status image being acquired for the first sample collection but not for subsequent sample collections. In this case, as shown in FIG. 5(B), the first collection status image stores the image file 11 obtained during the first sample collection, and remains unstored for subsequent sample collections. In such a case, if a collection error occurs in any of the multiple sample collections corresponding to a single measurement target sample, the image file 11 may be commonly displayed in image area AR1 of the error-related information screen.

[0077] Image area AR2 is an area where a second collection status image is presented to show the state in which the tip of probe 200 is immersed in the sample in container 300 before the corresponding sample is collected (aspirated). Image area AR3 is an area where a third collection status image is presented to show the state in which the tip of probe 200 is immersed in the sample in container 300 after the corresponding sample is collected (aspirated).

[0078] The information presented on the error-related information screen is not limited to the example shown in Fig. 6. For example, related information such as the sample ID, image capture date and time, and measurement item name corresponding to the collection status image may be presented in a predetermined format so as to be attached to each of the image areas AR1, AR2, and AR3. In this case, the position at which the related information such as the sample ID, image capture date and time, and measurement item name is presented may be any position within the image area AR (AR1, AR2, AR3) or may be outside the image area AR.

[0079] The user can understand the situation of the collection error that occurred from the error-related information screen of FIG. 6 . In addition to presenting error-related information, for example, in text, the error-related information screen of FIG. 6 displays collection status images during the corresponding sample collection operation in image areas AR1, AR2, and AR3. The collection status images displayed in image areas AR1, AR2, and AR3 allow the user to visually understand the state of the sample in container 300 before probe 200 is immersed in the sample, and the state of container 300 before and after sample collection with the tip of the probe immersed in container 300. This allows the user to accurately understand the situation of the collection error that occurred.

[0080] For example, by visually viewing the collection status image, the user may be able to understand the state inside the container 300 that would be difficult or impossible to detect using the sensor of the sensor unit 111. As an example, both FIGS. 7(A) and 7(B) show a state in which the tip of the probe 200 is immersed in the first layer LY1 of the sample inside the container. In addition, in FIG. 7(A), for example, the viscosity of the plasma in the first layer LY1 is high, resulting in a depressed liquid surface in the first layer LY1 that is in contact with the probe 200. On the other hand, in FIG. 7(B), for example, the viscosity of the plasma in the first layer LY1 is low, resulting in a raised liquid surface in the first layer LY1 that is in contact with the probe 200. This state of the sample liquid surface is an example of a state that is difficult to detect using the sensor of the sensor unit 111. By visually checking the second collection status image or the third collection status image presented in image area AR2 or image area AR3, the user can confirm the state of the sample liquid surface as shown in FIG. 7(A) or 7(B). When the user confirms the state of the sample liquid surface as shown in FIG. 7(A) or 7(B), the user can infer that, for example, abnormal sample viscosity is related to the cause of the collection error. In this way, the presentation of the collection status image on the error-related information screen can also contribute to inferring the cause of the collection error.

[0081] The collection status images presented in the image areas AR1, AR2, and AR3 may be enlarged in response to a user operation. By making the collection status images enlargeable, the user can check the contents of the collection status images in more detail.

[0082] [Example of Processing Procedure] An example of a processing procedure executed by the analytical device 100 of this embodiment in relation to the presentation of error-related information will be described with reference to the flowchart of Figure 8. The processing in this figure corresponds to a case where a single sample is collected from a container 300 corresponding to a single measurement target sample. The processing in this figure also corresponds to a case where an error is determined each time a sample is collected while consecutive samples are collected from a predetermined group of containers, and error-related information is presented in response to a determination that a collection error has occurred.

[0083] Step S100: In the analyzer 100, the measurement operation control unit 134 controls the transport of one container 300 from which a sample is to be collected from the storage position to the collection position of the measurement unit 101.

[0084] Step S102: In the case of an apparatus mechanism that requires rotation of the container 300, the measurement operation control unit 134 controls the measurement unit 101 to rotate the container 300, which is the collection target container placed at the collection position in step S100, so that the label attached to the container 300 is oriented so that it is not captured by the camera 102.

[0085] Step S104: The information acquisition unit 131 starts acquiring the detection information output by each sensor included in the sensor unit 111. Note that the start of acquiring the detection information as step S104 may be performed, for example, at the timing when the container 300 is rotated in step S102.

[0086] Step S106: After starting acquisition of detection information in step S104, the information acquisition unit 131 causes the camera 102 to perform a first image capture, as shown as operation procedure HW4 in Fig. 3. The information acquisition unit 131 acquires the image obtained by this image capture as a first collection status image.

[0087] 8, the determination unit 132 may determine whether or not a measurement impossible error has occurred based on the first collection status image at the stage when the first collection status image is acquired in step S106, as described above. If it is determined that a measurement impossible error has occurred, the measurement operation control unit 134 may suspend subsequent measurement-related operations.

[0088] Step S108: When acquisition of the first collection situation image in step S106 is completed, the measurement operation control unit 134 controls the lowering of the probe 200 so that the probe 200 enters the container 300 arranged at the collection position. As shown as operation procedure HW5 in Fig. 3 , the measurement operation control unit 134 stops the lowering of the probe 200 when the tip of the probe 200 is immersed to a predetermined depth in the sample in the container 300. For this reason, the measurement operation control unit 134 may further lower the probe 200 a predetermined distance after determining that the descending probe 200 has come into contact with the liquid surface based on the detection information output by the sensor unit 111.

[0089] Step S110: After the probe 200 has been lowered in step S108, the information acquisition unit 131 causes the camera 102 to capture a second image, as shown as operation procedure HW6 in FIG. 3 . The information acquisition unit 131 acquires the image obtained by this capture as a second collection status image. Note that a collection error may occur in which the probe 200 lowered in step S108 is mistakenly detected as having contacted the liquid surface at a position higher than the actual liquid surface of the sample. In this case, the processing of steps S112 and S114 (described below) may be skipped, and the process may proceed to step S116 without collecting a sample.

[0090] Step S112: After the second imaging in step S110 is completed, the measurement operation control unit 134 controls the probe 200 to aspirate the sample in the container 300, as shown in operation procedure HW7 in Figure 3, in order to collect the sample from the container 300.

[0091] Step S114: When the acquisition of the second collected image in step S112 is completed, the information acquisition unit 131, as shown in operation procedure HW8 in Fig. 3, causes the camera 102 to perform a third image capture while the probe 200, which is aspirating the sample, is inserted into the container 300. The information acquisition unit 131 acquires the image obtained by this image capture as a third collection status image.

[0092] Step S116: When acquisition of the third collection status image in step S114 is completed, the measurement operation control unit 134 controls the probe 200 inserted in the container 300 to be raised, and the probe 200 is removed from the container 300. By this control, the probe 200 is removed from the container 300, as shown in operation procedure HW9 in FIG. 3. The probe 200 removed from the container 300 is in a state in which the sample aspirated in step S112 is held in its hollow portion. Therefore, the measurement operation control unit 134 may control the measurement unit 101 to perform an operation of injecting the sample held in the probe 200 into a container for measurement.

[0093] Step S118: After the probe 200 is removed from the container 300 in step S116, the measurement operation control unit 134 controls the container 300, which was placed at the collection position, to be transported to a predetermined storage position, as shown in the operation procedure HW10 of Figure 3.

[0094] Step S120: Next, the determination unit 132 makes a determination regarding a collection error in the current sample collection. The determination unit 132 may make a determination regarding a collection error based on the detection information of the sensor unit 111 acquired in step S104. Furthermore, the determination unit 132 may also use the collection status images acquired in steps S106, S110, and S114 in addition to the detection information of the sensor unit 111. The determination unit 132 may determine whether a collection error has occurred in the current sample collection as a determination regarding a collection error. Furthermore, if the determination unit 132 determines that a collection error has occurred, it may also determine the type of collection error that has occurred.

[0095] Step S122: The information acquisition unit 131 generates collection status information ( FIG. 5(A) ) corresponding to the current sample collection. The collection status information may store the content of the judgment made in this step S120 as error information. The collection status information also stores the collection status images (first collection status image, second collection status image, third collection status image) acquired in steps S106, S110, and S114. The information acquisition unit 131 stores the generated collection status information in the collection status information storage unit 141.

[0096] Step S124: The information presenter 133 determines whether a collection error has occurred as a result of the determination made in the previous step S120. If it is determined in step S124 that a collection error has not occurred, step S126 may be skipped, the process in the figure may be terminated, and the process may proceed to, for example, the process for collecting the next sample.

[0097] Step S126: If it is determined in step S124 that a collection error has occurred, the information presenting unit 133 presents error information corresponding to the current sample collection. Specifically, the information presenting unit 133 generates an error information image based on collection status information corresponding to the current sample collection, and controls so that the generated error information image is displayed on the display unit 106 or a user terminal connected via communication.

[0098] In addition, in the case where a determination regarding a measurement impossible error is made at the stage when the first collection status image is acquired in step S106, if it is determined that a measurement impossible error has occurred, the container 300 may be transported to the storage position by the processing of step S118. Then, error information regarding the measurement impossible error may be presented, for example, in step S126.

[0099] 9 shows an example of the hardware configuration of the analysis device 100. The analysis device 100 in the figure includes a measurement unit 1001, a camera 1002, a user interface 1003, a communication device 1004, a ROM 1005, a RAM 1006, a storage 1007, a CPU 1008, and a GPU 1009. The measurement unit 1001, the camera 1002, the user interface 1003, the communication device 1004, the ROM 1005, the RAM 1006, the storage 1007, the CPU 1008, and the GPU 1009 are connected by a bus 1010.

[0100] The measuring unit 1001 is a portion where sample measurement is performed, and corresponds to the measuring unit 101 in FIG. 1 . The camera 1002 captures an image of a container placed at a collection position in the measuring unit 1001 from the side. The camera 1002 corresponds to the camera 102 in FIG. 1 . The user interface 1003 includes hardware corresponding to a user interface. Specifically, the user interface 1003 may include an input device (keys, buttons, a touch panel, a mouse, a keyboard, etc.) that is provided in the analysis device 100 or connected to the analysis device 100. The user interface 1003 may also include a display device, an audio output device, etc. that is provided in the analysis device 100 or connected to the analysis device 100.

[0101] The communication device 1004 is a device that supports communication via a network. The ROM 1005 stores non-rewritable data. The RAM 1006 temporarily stores data used for calculations performed by the CPU 1008 and GPU 1009. The storage 1007 is, for example, a hard disk drive (HDD) or a solid state drive (SSD), and stores various data including program data. The CPU 1008 executes programs stored in the storage 1007 to perform calculations corresponding to various controls and processes. The GPU 1009 executes processes related to image processing. Note that functions equivalent to those of the analysis device 100 may be achieved by multiple network-compatible devices that are distributed over a network so that predetermined processes can be performed.

[0102] <Modifications> Modifications of the above embodiment will be described below. [First Modification] A plurality of cameras 102 may be provided so as to capture images of the side surface of the container 300 from different directions. In this case, the information acquisition unit 131 may acquire a plurality of first collection status images, second collection status images, and third collection status images corresponding to each of the plurality of cameras 102, and store them in the collection status information.

[0103] [Second Modification] The information presenting unit 133 may identify, from among the first to third collection status images, a collection status image that is highly associated with the error type determined in a collection error that occurred during sample collection corresponding to the displayed error-related information screen ( FIG. 6 ). In this case, for example, the information presenting unit 133 may identify, as the collection status image highly associated with the determined error type, a collection status image captured at a timing closest to the operational procedure in which the determined error type is most likely to occur. The information presenting unit 133 may highlight, in a predetermined manner, the image area in which the identified collection status image is displayed among the image areas AR1, AR2, and AR3 on the error-related information screen. Furthermore, the information presenting unit 133 may select and display, on the error-related information screen, the image area of ​​the collection status image that is identified as highly associated with the determined error type among the image areas AR1, AR2, and AR3.

[0104] [Third Modification] As a specific example in which some of the first to third collection status images may be displayed on the error-related information screen, for example, in a situation in which it has been determined that an event that could cause a collection error will hardly occur before sample collection, two collection status images may be displayed: a first collection status image that serves as a reference, and a third collection status image after sample collection. In this case, the collection status images that are not displayed on the error-related information screen may not be captured during the sample collection operation.

[0105] [Fourth Modification] In the above embodiment, the collection status image is a still image, but the collection status image may be a video captured by continuously capturing operation procedures HW2 to HW9 in Fig. 3 corresponding to one sample collection. In this case, for example, the information acquisition unit 131 may add a timestamp or set a chapter break to the video collection status image at the timing of operation procedures HW4, HW6, and HW8 in Fig. 3 that captured the first to third still collection status images, or at the timing corresponding to the occurrence of a collection error.

[0106] In the above embodiment, the determination unit 132 is configured to determine whether a collection error, which is an abnormality that occurs when a sample is being collected. In this modification, the determination unit 132 may be configured to determine whether there is an abnormality in the measurement result obtained when the sample collected by the measurement unit 101 is measured as the measurement target.

[0107] In this case, the information acquiring unit 131 may acquire the measurement results of the sample collected as the measurement target from the measurement unit 101, and store measurement result information indicating the measurement results in the storage unit 104. The information acquiring unit 131 may store the measurement result information for each measurement item of the sample to be measured in the storage unit 104. Alternatively, the measurement result information may be stored in the collection status information shown in FIG. 4 or FIG. 5.

[0108] The determination unit 132 may determine whether or not the measurement results are abnormal for each measurement item of the sample to be measured based on the measurement results indicated by the measurement result information obtained as described above. The determination unit 132 may determine whether or not the measurement results are abnormal, for example, depending on whether the measurement values ​​indicated by the measurement results are outside the normal range. Alternatively, for example, a user may visually check the measurement results and, for measurement results for which the measurement values ​​are determined to be abnormal, perform an operation to assign a flag indicating that the measurement results are abnormal. In this case, the determination unit 132 may determine whether or not the measurement results are abnormal based on whether or not a flag is assigned to the measurement results.

[0109] The information presenting unit 133 may display an anomaly-related information screen showing measurement results for which the determining unit 132 has determined that an anomaly has occurred on the display unit 106 or a user terminal. In this case, the information presenting unit 133 may include, in the anomaly-related information, a collection status image obtained when collecting the sample corresponding to the measurement result for which an anomaly has occurred. Such an anomaly-related information screen may be in a form similar to the error-related information screen of FIG. 6. In this case, the anomaly-related information screen also includes the collection status image. This allows the user to appropriately determine the anomaly in the measurement results, including the influence of the collection error.

[0110] In this modified example, the abnormality-related information screen may be displayed when the judgment unit 132 judges that the measurement results obtained from the measurement unit 101 are abnormal while the measurement unit 101 is sequentially measuring the samples to be measured.

[0111] Furthermore, after the measurement of a group of measurement target samples is completed, a list of measurement results, including measurement results determined to be abnormal by the determination unit 132, may be displayed on the display unit 106 or the user terminal. In this case, the list of measurement results may be a list of extracted measurement results determined to be abnormal, or may be a list of measurement results for each measurement of a group of measurement target samples, in which measurement results determined to be abnormal are presented in a predetermined manner so that they can be identified. The user may then be able to select a measurement result they wish to view from among the measurement results determined to be abnormal in the list of measurement results. The information presentation unit 133 may be configured to display an abnormality-related information screen showing the measurement result selected by operation.

[0112] The user may also be able to select any measurement result item from the list of measurement results. The information presenter 133 may display a measurement result information screen presenting details of the measurement result corresponding to the selected item and collection status information. Such a measurement result information screen may be similar to the error-related information screen of FIG. 6, for example. In this case, if the user determines that a certain measurement result in the list of measurement results is suspected to be abnormal, the user can immediately check the details of the measurement result together with the imaging status image.

[0113] [Sixth Modification] The probe 200 may be structured to be integrated with a piercer that pierces the lid of the container 300 when collecting a sample from the container 300.

[0114] [Seventh Modification] Note that the configuration may be such that predetermined functions of the analysis device 100 are distributed and assigned to each of a plurality of devices, and the plurality of devices are connected via communication and cooperate with each other to realize the functions of the analysis device 100.

[0115] Alternatively, a program for implementing the functions of the analysis device 100 may be recorded on a computer-readable recording medium, and the program may be loaded into a computer system and executed to perform the processing of the analysis device 100. 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" herein includes hardware such as an operating system (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 term "computer-readable recording medium" refers to portable media such as floppy disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into computer systems. Thus, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM. The term "recording medium" also includes internal or external recording media accessible from a distribution server for distributing the program. The program code stored on the distribution server's recording medium may be different from the program code executable on a terminal device. In other words, the format in which the program is stored on the distribution server is not important as long as it can be downloaded from the distribution server and installed in a form that is executable on a terminal device. The program may be divided into multiple parts, each downloaded at a different time and then combined on a 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 serves as a server or client when a program is transmitted over a network. The program may also be a program that realizes part of the above-described functions. Furthermore, the program may be a so-called differential file (differential program) that can realize the above-described functions in combination with a program already stored in the computer system.
