[0025] Hereinafter, a preferred embodiment of the container storage device will be described with reference to the accompanying drawings. In the embodiment, a specimen in a liquid analyzed by an automatic analysis system will be described. In addition, the container for containing the liquid includes a specimen container for containing the specimen, a reagent bottle for containing the reagent, etc. In addition, in the following description and the accompanying drawings, for components having the same functional structure, repeated description is omitted by marking the same reference numerals.

[0026] Example 1

[0027] use Figure 1 , an example of the overall structure of the automatic analysis system is described. The automatic analysis system is a system for analyzing a precision management sample for precision management, a specimen such as blood and urine provided by a patient, and includes an automatic analysis device 100 and a container storage device 101. The automatic analysis device 100 includes a specimen carrying-in unit 102, a specimen carrying-out unit 103, a rack conveying line 104, a rack information acquisition unit 105, a detection unit 112, an operation unit 111, a control unit 113, and a recording device 114. The container storage device 101 includes a buffer 106, a rack stop unit 107, a specimen moving mechanism 108, a specimen storage module 109, and a specimen information acquisition unit 110. Each unit is described below.

[0028] In the specimen loading unit 102, a specimen container containing a specimen is loaded. The specimen container is mounted on a rack, and the loading of the specimen container is performed by an operator. In the specimen unloading unit 103, the specimen container mounted on the rack is unloaded. The unloaded specimen container is received by the operator.

[0029] In the rack conveyor line 104, it is connected to the specimen loading unit 102, the specimen unloading unit 103, the detection unit 112, and the container storage device 101, and conveys the rack between them. The rack information acquisition unit 105 is provided on the rack conveyor line 104 and reads the identifier attached to the rack, such as the barcode pasted on the rack.

[0030] The detection unit 112 includes a photomultiplier tube, a light source lamp, a spectroscope, and a photodiode, and performs the measurement of the specimen. The detection unit 112 may also have a function of adjusting the internal temperature.

[0031] The operation unit 111 includes, for example, a display, a touch panel, a mouse, a keyboard, etc., and is used to input instructions from the operator related to the loading and unloading of the specimen and the measurement, or to display the data related to the loading and unloading of the specimen and the measurement result. The control unit 113 controls each unit according to the instructions input to the operation unit 111 and various programs read from the recording device 114. Various programs, data related to the loading and unloading of the specimen, and the measurement are recorded in the recording device 114.

[0032] Empty racks for conveying the specimen container are stored in the buffer 106. In addition, at least one empty rack is stored in the buffer 106 so as not to interfere with the conveyance of the specimen container. When the unloading of the specimen container is requested, the specimen container is mounted on the empty rack stored in the buffer 106, and the rack mounted with the specimen container is unloaded to the specimen unloading unit 103. In addition, the rack used in the loading of the specimen container is stored in the buffer 106 after the loading of the specimen container and is used in the unloading of other specimen containers.

[0033] The rack stop unit 107 is provided on the rack conveyor line 104 and is a place for loading and unloading the specimen container from the rack. That is, the specimen container is unloaded from the rack conveyed to the rack stop unit 107 by the specimen loading unit 102, or the specimen container is loaded onto the rack stopped at the rack stop unit 107. The loading and unloading of the specimen container in the rack stop unit 107 is performed by the specimen moving mechanism 108.

[0034] The specimen moving mechanism 108 moves the specimen container unloaded from the rack to the specimen storage module 109, or loads the specimen container in the specimen storage module 109 into the rack stopped at the rack stop unit 107.

[0035] In the specimen storage module 109, a plurality of storage locations for storing specimen containers are provided. In addition, in order to keep the temperature of the specimen contained in the specimen container constant, the specimen storage module 109 is provided with a temperature adjustment mechanism. Further, when the number of storage locations in the specimen storage module 109 is M and the number of specimen containers stored in the specimen storage module 109 is N, M - N idle locations are generated in the specimen storage module 109.

[0036] The specimen information acquisition unit 110 is provided on the movement path of the specimen transfer mechanism 108, and reads the identifier assigned to the specimen container entering and leaving the specimen storage module 109, for example, the barcode pasted on the specimen container. The identifier of each specimen container corresponds to the data related to the specimen.

[0037] Using Figure 2A , an example of a specimen table that associates the identifier of the specimen container with the data related to the specimen will be described. Figure 2A The illustrated specimen table has columns for specimen ID, remaining amount, expiration date, OBS, storage location, and removal flag, and is recorded in the recording device 114.

[0038] In the column of specimen ID, the identifier of the specimen container is recorded. In the column of remaining amount, the amount of the specimen remaining in the specimen container is recorded. In the column of expiration date, the period during which the specimen contained in the specimen container can be used is recorded. In the column of OBS (OnBoard Stability), the period during which the specimen can be used after the specimen container is opened is recorded. In the column of storage location, the location in the specimen storage module 109 where the specimen container is stored is recorded. In the column of removal flag, a flag indicating that the specimen container is a candidate for removal is recorded. That is, in Figure 2A , for the specimen container with specimen ID C, the remaining amount is V_C, the expiration date is EXD_C, the OBS is OBS_C, the storage location is P_C, indicating that it is a candidate for removal. In addition, the data related to each rack can be associated with the identifier of each rack.

[0039] Using Figure 2B , an example of a rack table that associates the identifier of the rack with the data related to the rack will be described. Figure 2B The illustrated rack table has columns for rack ID and specimen ID, and is recorded in the recording device 114. In the column of rack ID, the identifier of the rack is recorded. In the column of specimen ID, the identifier of the specimen container mounted on the rack is recorded.

[0040] Using Figure 3 , an example of the processing flow of precision management will be described step by step.

[0041] (S301)

[0042] The control unit 113 receives a measurement instruction input by an operator via the operation unit 111.

[0043] (S302)

[0044] The control unit 113 controls the specimen moving mechanism 108 to take out a specimen container from the specimen storage module 109.

[0045] (S303)

[0046] The control unit 113 determines whether the specimen contained in the specimen container taken out in S302 can be used. If the specimen cannot be used, the process returns to S302 via S303. If the specimen can be used, the process proceeds to S305.

[0047] For example, it is determined whether the specimen can be used based on the data in the Figure 2A recorded specimen table. That is, when the remaining amount corresponding to the identifier of the specimen container read by the specimen information acquisition unit 110 does not meet the amount required for measurement, or exceeds the expiration date or OBS, it is determined as unusable.

[0048] (S304)

[0049] The control unit 113 registers the specimen container determined to be unusable in S303 as a candidate for removal. For example, it is registered as a removal candidate by recording 1 in the Figure 2A removal flag of the recorded specimen table. After the registration as a removal candidate is completed, the specimen container that has not been taken out is taken out in S302.

[0050] (S305)

[0051] The control unit 113 causes the detection unit 112 to measure the specimen determined to be usable in S303. More specifically, the specimen container containing the usable specimen is mounted on the rack stopped in the rack stop unit 107 by the specimen moving mechanism 108 and transported to the detection unit 112 through the rack transport line 104.

[0052] (S306)

[0053] The control unit 113 transports the specimen container that has completed the measurement in S305 to the container storage device 101. More specifically, the measured specimen container is transported to the container storage device 101 through the rack transport line 104 while being mounted on the rack for transporting to the detection unit 112.

[0054] (S307)

[0055] The control unit 113 determines whether the remaining amount of the specimen contained in the specimen container transported in S306 is sufficient. If the remaining amount is sufficient, the process proceeds to S309. If the remaining amount is insufficient, the process proceeds to S309 via S308.

[0056] (S308)

[0057] The control unit 113 registers the specimen container determined to have insufficient remaining amount in S307 as a candidate for removal. The registration of the removal candidate is the same as in S304.

[0058] (S309)

[0059] The control unit 113 controls the specimen moving mechanism 108 to store the specimen container transported in S306 in the specimen storage module 109.

[0060] (S310)

[0061] The control unit 113 stores the rack used for transporting the specimen container in S306 in the buffer 106.

[0062] By using Figure 3 the processing flow described above, precision management is implemented, and the specimen containers determined to be unusable are registered as candidates for removal. If the specimen storage module 109 is filled with a large number of specimen containers as removal candidates, it becomes difficult to store a certain number of usable specimen containers. Therefore, it is preferable to remove the specimen containers as removal candidates in a timely manner. In addition, since the loading and unloading of specimens are performed by the operator, for example, when a new specimen container is loaded, if the specimen containers as removal candidates are removed, the burden on the operator is reduced.

[0063] Using Figure 4 , as an example of the processing flow of Embodiment 1, the case of removing unusable specimen containers when a new specimen container is loaded is described step by step.

[0064] (S401)

[0065] The control unit 113 receives the specimen loading instruction input by the operator via the operation unit 111. In addition, after the operator loads the rack with the new specimen container into the specimen loading unit 102, the operator operates the operation unit 111. The rack with the new specimen container is transported to the rack information acquisition unit 105 through the rack transport line 104, and the identification number of the rack is read by the rack information acquisition unit 105.

[0066] (S402)

[0067] The control unit 113 obtains the number of specimens removed. For example, count the number of specimens with the removal flag recorded in the specimen table Figure 2A illustrated.

[0068] (S403)

[0069] The control unit 113 determines whether there is sufficient free space in the specimen storage module 109 after the specimen container has been removed. If there is insufficient free space, the process returns to S403 via S404. If there is sufficient space, the process proceeds to S405.

[0070] Based on the number of newly loaded specimen containers, it is determined whether there is sufficient free space in the specimen storage module 109 after the specimen container has been removed. That is, if the number of free spaces after removal is equal to or greater than the number of newly loaded specimen containers, it is determined to be sufficient. If the number of free spaces does not meet the number of newly loaded containers, it is determined to be insufficient.

[0071] (S404)

[0072] The control unit 113 requests the operator to input the removal conditions. That is, if there is insufficient free space, the newly loaded specimen containers cannot be stored in the specimen storage module 109. Therefore, the operator is requested to input the conditions for extracting additional specimen containers to be removed, i.e., the removal conditions. Figure 5A An example of a screen indicating the request for input of the removal conditions is shown. Additionally, if the removal conditions are input, a determination regarding the free space in the specimen storage module 109 after the specimen container is removed again is made in S403.

[0073] (S405)

[0074] The control unit 113 determines whether the number of empty racks stored in the container storage device 101 is sufficient. If the number of empty racks is insufficient, the process returns to S405 via S406. If there are sufficient empty racks, the process proceeds to S407.

[0075] Based on a predetermined threshold value, it is determined whether the number of empty racks stored in the container storage device 101 is sufficient. That is, if the number of racks is equal to or greater than the threshold value, it is determined to be sufficient. If the number of racks does not meet the threshold value, it is determined to be insufficient. The threshold value can be, for example, the minimum number (i.e., 1) that does not impede the transportation of specimen containers, or it can be the maximum number that the container storage device 101 can store. If the threshold value is the maximum number, the risk of stopping the transportation of specimen containers can be minimized.

[0076] (S406)

[0077] The control unit 113 requests the operator to replenish the empty racks. That is, if the number of empty racks is insufficient, it impedes the transportation of specimen containers. Therefore, the operator is requested to replenish the empty racks. Figure 5B An example of a screen indicating the request for replenishment of empty racks is shown. Additionally, if the empty racks are replenished according to the replenishment request, a determination regarding the number of empty racks is made again in S405.

[0078] (S407)

[0079] The control unit 113 performs the unloading and loading of the specimen containers. More specifically, after unloading the test containers that are candidates for unloading and the test containers that meet the unloading conditions onto the racks supplied from the buffer 106 and then unloading them, the specimen containers indicated in S401 are loaded, and the racks used for loading are stored in the buffer 106.

[0080] In addition, when there are multiple racks for loading the specimen containers, the racks used for loading can also be used for unloading the test containers that are candidates for unloading and the test containers that meet the unloading conditions. By using the racks used for loading for unloading, the number of empty racks stored in the container storage device 101 can be not reduced.

[0081] By using Figure 4 the processing flow described above, when a new specimen container is loaded, the unusable specimen containers are unloaded, thus reducing the burden on the operator involved in unloading and loading the specimens. In addition, when performing Figure 3 、 Figure 4 the processing flow, the screen related to the operation can also be displayed on the operation unit 111.

[0082] Using Figure 6 as an example of the interface related to precision management, the precision management screen 600 is described. The precision management screen 600 includes a menu button 601, a routine operation button 602, a device status button 603, a maintenance button 604, an alarm button 605, a report button 606, a stop button 607, a start button 608, and a precision management storage button 609.

[0083] The menu button 601 is pressed when displaying a menu-related screen. The routine operation button 602 is pressed when displaying a routine-related screen. The device status button 603 is pressed when displaying a device status-related screen. The maintenance button 604 is pressed when displaying a maintenance-related screen. The alarm button 605 is pressed when displaying an alarm-related screen. The report button 606 is pressed when displaying a report-related screen. The stop button 607 is pressed when instructing the stop of the operation. The start button 608 is pressed when starting actions such as analysis processing. The precision management storage button 609 is pressed when displaying the in-specimen storage module status screen 610.

[0084] The in-specimen storage module status screen 610 includes a precision management specimen button 611, a setting button 612, a loading button 613, an unloading button 614, and a close button 615. The precision management specimen button 611 is pressed when displaying the specimen information table 616. The setting button 612 is pressed when setting the unloading conditions. The loading button 613 is pressed when instructing specimen loading. The unloading button 614 is pressed when instructing specimen unloading. The close button 615 is pressed when closing the in-specimen storage module status screen 610.

[0085] The specimen information table 616 has columns of ck, status, location, specimen name, batch number, expiration date, use, test, and OBS. The ck column is a check box that is checked when the corresponding row is selected. The status of the specimen is displayed in the status column. The storage location of the specimen is displayed in the location column. The name of the specimen is displayed in the specimen name column. The batch number of the specimen is displayed in the batch number column. The expiration date of the specimen is displayed in the expiration date column. In the use column, whether the specimen can be used is displayed. The test items of the specimen are displayed in the test column. In the OBS column, the expiration date after the specimen container is opened is displayed. Figure 6 In the sample information table 616, the sample in the second row is selected as scheduled to be carried out, and when the carry-out button 614 is pressed, the carry-out instruction is issued.

[0086] Furthermore, when there are a plurality of racks carrying sample containers to be carried in, the plurality of racks may be placed on standby at a stage preceding the sample carrying-in unit 102 . Figure 7 FIG. 1 shows an automatic analysis system in which a sample standby unit 700 is provided at a stage preceding the sample carrying unit 102. Figure 1 The difference in the sample standby unit 700 will be described.

[0087] The specimen standby section 700 stores a plurality of racks carrying specimen containers to be carried in, and carries the plurality of racks into the specimen carrying-in section 102 in sequence. In addition, in order to keep the temperature of the specimens contained in the specimen containers constant, the specimen standby section 700 has a temperature adjustment mechanism. Furthermore, a barcode reader, a camera, etc. may be provided in the specimen standby section 700. By providing a barcode reader and a camera, the number of racks stored in the specimen standby section 700 and the types of specimens in the specimen containers carried in the racks can be recorded in the recording device 114. Furthermore, it is also possible to determine whether there are specimen containers that cannot be used based on the data recorded in the recording device 114.

[0088] Example 2

[0089] In Example 1, a case where an unusable specimen container is carried out in conjunction with an operator's specimen carrying-in instruction is described. The carrying-out and carrying-in of specimens are not limited to Example 1. In Example 2, a case where the automatic analysis system that has confirmed the specimen carried out notifies a request to carry in a new specimen is described. In addition, the difference from Example 1 lies in the processing flow, so the descriptions other than this are omitted.

[0090] use Figure 8 , the processing flow of Example 2 is explained step by step.

[0091] (S402)

[0092] As in the first embodiment, the control unit 113 obtains the number of samples carried out.

[0093] (S800)

[0094] The control unit 113 notifies the operator of a request to carry in a new sample. That is, the operator is requested to carry in a new sample in order to carry in a new sample container in conjunction with the unusable sample container being carried out. Figure 9 An example of a screen for notifying a request for carrying in a new sample is shown. If the operator inputs a sample carrying instruction via the operation unit 111, the processes after S403 are executed.

[0095] (S403~S407)

[0096] Similar to the first embodiment, the control unit 113 checks the vacant spaces and the number of racks in the sample storage module 109 and then carries out the loading and unloading of sample containers.

[0097] By using Figure 8 In the processing flow described, when unusable specimen containers are taken out, new specimen containers are taken in, thereby reducing the burden on operators involved in taking in and out specimens. In addition, by timely entrusting the new specimens to be taken in, operators will not forget to put in the new specimens. In addition, since a certain number of usable specimens are stored in the automatic analysis system, the automation of the analysis will not be hindered.

[0098] Example 3

[0099] In Example 1 and Example 2, the processing flow is described using the operator's sample carry-in instruction as a trigger. In Example 3, the processing flow is described using the operator's sample carry-out instruction as a trigger. In addition, the difference from Example 1 and Example 2 lies in the processing flow, so the description other than this is omitted.

[0100] use Figure 10 , the processing flow of Example 3 is explained step by step.

[0101] (S1001)

[0102] The control unit 113 receives a sample unloading instruction input by the operator via the operation unit 111. The sample unloading instruction is input, for example, by Figure 6 This is done by selecting a specimen in the specimen information table 616 of the accuracy management screen 600 and pressing the carry-out button 614 .

[0103] (S402)

[0104] As in the first embodiment, the control unit 113 obtains the number of samples carried out.

[0105] (S405~S406)

[0106] Similarly to Embodiment 1, the control unit 113 confirms the number of empty racks stored in the container storage device 101, and if it is insufficient, notifies a replenishment order.

[0107] (S1007)

[0108] The control unit 113 performs the removal of the specimen containers. More specifically, the specimen containers instructed to be removed in S1001 and the test containers as removal candidates are loaded onto the racks supplied from the buffer 106 and removed. In addition, the specimen containers instructed to be removed and the test containers as removal candidates may be removed using the same rack or different racks. In the case of removing using the same rack, the time required for removing the specimen containers can be shortened. In the case of removing using other racks, it is easy to distinguish between the specimen containers instructed to be removed and the test containers as removal candidates.

[0109] By using Figure 10 the processing flow described above, when the specimen containers instructed to be removed by the operator are removed, the specimen containers as removal candidates are also removed, so the burden on the operator related to the removal of the specimens is reduced. In addition, since the specimen containers are automatically removed, the operator does not need to standby near the specimen removal unit 103, and can perform the processing accompanying the removal of the specimens at an arbitrary timing.

[0110] As described above, multiple embodiments of the present invention have been described. The present invention is not limited to the above embodiments, and the components can be modified without departing from the gist of the invention. In addition, multiple components disclosed in the above embodiments can be appropriately combined. Moreover, several components can be deleted from all the components shown in the above embodiments.
