  In such an automatic analyzer, when a new sample is added during the analysis, the analysis is interrupted once, the sample to be added is placed on the sample disk, and then the analysis is resumed. When resuming the analysis, the information for identifying the sample such as the patient ID of the sample installed on the sample disk is read to recognize the presence or absence of the added sample while the analysis is suspended. it can.

  By the way, in such an automatic analyzer, the analysis of the sample newly added to the sample disk (hereinafter referred to as “additional sample”) while the analysis is suspended is performed before the analysis is suspended. This is performed after the analysis of the sample already installed on the sample disk (hereinafter referred to as “installed sample”) is completed. Even when the additional sample and the installed sample are in the same sample category (for example, emergency sample / general sample), the analysis of the additional sample is performed after the analysis of the installed sample in the same sample category is completed. It will be broken. If the analysis is interrupted and a sample that is more urgent than the installed sample is added to the sample disk and this additional sample is analyzed earlier than the installed sample, the same sample classification as the additional sample When the sample is installed on the sample disc as an installed sample, it is necessary to wait for the analysis of the additional sample with a high degree of urgency until the analysis of the installed sample is completed. There is also a desire to change the analysis order for each sample according to the degree of urgency of the sample.

  Hereinafter, embodiments of the present invention (hereinafter simply referred to as “embodiments”) will be described in detail with reference to the drawings. In addition, this invention is not limited to the following embodiment, A various change is possible in the range which does not deviate from the summary. First, a schematic configuration of the entire automatic analyzer will be described with reference to FIG. FIG. 1 is a diagram showing an overall schematic configuration of the automatic analyzer. As shown in FIG. 1, the automatic analyzer 1 includes an analysis unit 8 that automatically analyzes a sample, and an operation unit 100 that operates the analysis unit 8.

  The operation unit 100 is configured by a general computer. The operation unit 100 includes a keyboard 102 and a mouse 103 as input devices for an operator to input data. In addition, a display device 104 for displaying data and a data printing device are provided. A printing apparatus 105 and an interface 106 for connecting to the analysis unit 8 are provided.

  In addition, the operation unit 100 includes a storage device 107 that stores various types of information such as an “analysis order table” described later. The computer 110 of the operation unit 100 is configured to be able to update various information stored in the storage device 107. In addition, the computer 110 is configured to transmit various information stored in the storage device 107 to the computer 22 of the analysis unit 8.

  The analysis unit 8 is connected to the operation unit 100 via the interface 106. The analysis unit 8 includes a reaction disk 9, and a plurality of reaction vessels 10 are installed on the concentric circumference of the reaction disk 9. The reagent disk 11 is provided with a plurality of reagent bottles 12 containing various reagents on a concentric circle. Around the reaction disk 9, a sample dispensing probe 13, a stirring device 14, a cleaning device 15, a light source 16, and a multiwavelength photometer 17 are arranged. A reagent dispensing probe 18 is disposed between the reaction disk 9 and the reagent disk 11. A sample disk 19 is installed on the rotation circumference of the sample dispensing probe 13 and next to the reagent disk 11. A plurality of sample containers 20 containing samples are installed in the sample disk 19. All the operations of these mechanisms are controlled by the computer 22 via the interface 21.

  The operator uses the display device 104 of the operation unit 100, the keyboard 102, or the mouse 103 to request a measurement item from the computer 110 and gives an analysis instruction from the computer 110 to the analysis unit 8. The analysis instruction is transmitted from the computer 110 to the analysis unit 8 via the interfaces 106 and 21. The analysis unit 8 performs the following analysis operation according to the received analysis instruction.

  The analysis unit 8 causes the sample dispensing probe 13 to dispense a predetermined amount of the sample contained in the sample container 20 by the number of requested items. After completing the dispensing for one sample container 20, the analysis unit 8 rotates the sample disk 19 so that the next sample container 20 is directly below the sample dispensing probe 13. The reaction container 10 into which the sample has been dispensed rotates on the reaction disk 9 by the rotation of the reaction disk 9. Meanwhile, for the sample in the reaction container 10, the reagent in the reagent bottle 12 is dispensed by the reagent dispensing probe 18, the reaction liquid is stirred by the stirring device 14, the light source 16 and the multiwavelength photometer 17. The absorbance is measured by the above. Thereafter, the reaction vessel 10 is cleaned by the cleaning device 15.

  The measured absorbance signal enters the computer 22 of the analysis unit 8 via the interface 21 via the A / D converter 23. From the absorbance signal, the computer 22 calculates calibration curve data from the set concentration data in the case of a standard solution sample based on an analysis method set in advance for each analysis item, and in the case of a patient sample and a control sample. Concentration data is calculated from calibration curve data obtained by measuring a standard solution sample. These data are added with information obtained by symbolizing the type of the sample as a measurement result in the computer 22. In this way, the analysis unit 8 analyzes the sample installed on the sample disk 19. The analysis result is transmitted from the computer 22 of the analysis unit 8 to the computer 110 of the operation unit 100 via the interfaces 21 and 106. The computer 110 of the operation unit 100 stores the received analysis result in the storage device 107 and outputs it to the display device 104 and the printing device 105. In this way, the computer 110 of the operation unit 100 causes the analysis unit 8 to analyze each sample installed on the sample disk 19. The computer 110 of the operation unit 100 determines the analysis order of each sample in the analysis unit 8.

  In the automatic analyzer 1, when adding a new sample during analysis, the operation unit 100 once interrupts the analysis of the sample in the analysis unit 8, and after the additional sample is newly installed on the sample disk 19, The analysis unit 8 restarts the suspended analysis. When the analysis is resumed, the sample barcode reader 24 is added while the analysis is suspended by reading information for identifying the sample such as the patient ID of the sample installed on the sample disk 19. The computer 22 of the analysis unit 8 and the computer 110 of the operation unit 8 can recognize the presence or absence of the additional sample.

  By the way, among the samples described above, there is an “emergency sample” that is a sample that is more urgent than other samples, that is, a sample with high urgency. Such an urgent sample is distinguished from other samples that are comparatively urgent, that is, “general samples”. The emergency sample needs to be analyzed with priority over the general sample. In order to distinguish such an urgent sample from a general sample, information indicating a “sample category”, which is a category for identifying a sample, is attached to, for example, a container (not shown) containing the sample. The automatic analyzer 1 can read information indicating the sample classification of the sample from the container and reflect it in the analysis work.

  In an analyzer that performs analysis by installing a plurality of specimens on the sample disk 19 as in the automatic analyzer 1 described above, when an emergency specimen is already installed as a “installed specimen” on the sample disk 19, When a request for testing an emergency sample (additional sample), which is more urgent among urgent samples, occurs suddenly, such as response, until the analysis of the emergency sample (installed sample) already installed on the sample disk 19 is completed The emergency sample (additional sample) could not be analyzed. There is also a demand to change the analysis order in units of specimens according to the degree of urgency of specimens even for specimens of the same specimen category.

  Therefore, in the automatic analyzer 1 of the present embodiment, the computer 110 of the operation unit 100 adds “additional sample” to the sample disk 19 while the analysis of the sample installed on the sample disk 19 is interrupted. "Analysis control" is performed so that the analysis unit 8 first analyzes the "compared sample" with the "installed sample" that has already been installed on the sample disk 19 before the analysis is terminated. This will be described below with reference to FIGS. FIG. 2 is a diagram illustrating an example of a “start condition screen” that is a screen for setting conditions for starting analysis control executed by the automatic analyzer according to the present embodiment. FIG. 3 is a flowchart showing analysis control executed by the automatic analyzer according to the present embodiment. FIG. 4 is a diagram illustrating an example in which an “analysis order table” which is a table indicating the analysis order of each sample in the analysis unit of the automatic analyzer according to the present embodiment is displayed on the screen of the display unit of the operation unit. is there.

  As shown in FIG. 1 and FIG. 2, in the automatic analyzer 1 of the present embodiment, first, the computer 110 of the operation unit 100 sets a screen for setting analysis control start conditions on the display device 104 (hereinafter, “ 2), which is referred to as “start condition screen” (see FIG. 2). When the button 35 displayed as “Start” is selected on the start condition screen 30, analysis is started in the analysis unit 8 of the automatic analyzer 1. Specifically, the sample disk 19 rotates, and the sample barcode reader 24 reads the “patient ID” on the barcode attached to the sample container 20 to recognize the sample newly added to the sample disk 19. To do. As a result, when the computer 22 controls the operation of various devices constituting the analysis unit 8 of the automatic analyzer 1, it is possible to analyze the additional sample with priority or top priority.

  In the following description, a sample newly added to the sample disk 19 when the analysis is interrupted during the analysis of the sample is simply referred to as “additional sample”. On the other hand, a sample already installed on the sample disk 19 before the analysis is interrupted is referred to as “installed sample”.

  As shown in FIG. 2, the computer 110 of the operation unit 100 displays “installed sample” which is a radio button that gives priority to the analysis of the installed sample over the additional sample in the analysis priority setting item 31 of the start condition screen 30. A “priority” radio button 32 and an “additional sample priority” radio button 33 which is a radio button for giving priority to the analysis of the additional sample over the installed sample are displayed.

  In step S02 of FIG. 3, the computer 110 of the operation unit 100 registers the “installed sample” already installed on the sample disk 19 in the analysis order table 40 (an example is shown in FIG. 4). Information on the installed specimen is sent to the computer 110 when the specimen barcode reader 24 reads the barcode attached to the sample container 20. Information regarding the installed specimen may be input by the operator using the input devices 102 and 103 and sent to the computer 110.

  When the operator selects the additional sample priority radio button 33 in the analysis priority setting item 31 in FIG. 2 and installs a new sample (that is, an additional sample) in the sample disk 19, the operation unit 100 The computer 110 determines in step S04 in FIG. 3 that there is an additional sample (Yes), and registers the additional sample so that the additional sample is preferentially analyzed compared to the installed sample in step S06. To do. Specifically, as shown in FIG. 4, the computer 110 registers the additional sample among the additional sample and the installed sample in the same sample category in the head of the analysis order table 40, that is, the highest order. To do. The installed samples in the same sample category (for example, urgent sample / general sample) as this additional sample are shifted to the next order of the additional sample in the analysis order table 40, that is, the lower order compared to the additional sample. Register with. In addition, when the classification (for example, urgent specimen / general specimen) is different between the installed specimen and the additional specimen, the analysis order of the analysis order table 40 is registered according to the degree of urgency indicated by the classification. Also good. Then, the process proceeds to step S08.

  On the other hand, if it is determined in step S04 that there is no additional sample (No), the computer 110 proceeds to step S08 while keeping the analysis order table registered in step S02 as it is.

  In step S08, the computer 110 of the operation unit 100 of the automatic analyzer 1 causes the analysis unit 8 to analyze each sample according to the analysis order table 40. Specifically, the computer 110 of the operation unit 100 reads information about the sample in order from the upper side of the analysis order table 40 and transmits an analysis instruction to the computer 22 of the analysis unit 8. The computer 22 controls various devices and mechanisms that constitute the analysis unit 8, and analyzes each sample.

  Thus, in the above-described example, when there are an installed sample and an additional sample in the same sample classification (for example, emergency sample / general sample), the additional sample is compared with the installed sample first (the first sample). The computer 110 registers an additional sample at the highest level of the analysis order table 40 for analysis. That is, when the additional sample and the installed sample are in the same sample category, the computer 110 of the operation unit 100 causes the analysis unit 8 to analyze the additional sample before the installed sample.

  However, the manner of registering each sample in the analysis order table 40 is not limited to this example. For example, if there is a “reserved (analysis scheduled) sample” that has already been given an analysis instruction from the computer 110 of the operation unit 100 to the analysis unit 8 or a sample that is already being analyzed, an additional sample is analyzed. It is also preferable to register in the next analysis order of the sample in the middle and the “reserved (analytical scheduling) sample”.

  In the above example, the case where the operator selects the additional specimen priority radio button 33 has been described. However, in the analysis priority setting item 31 on the start condition screen 30 in FIG. 2, the operator selects the installed sample priority radio button 32 and adds a new sample (additional sample) to the sample disk 19 for installation. In some cases. In this case, the computer 110 of the operation unit 100 determines whether the additional sample and the installed sample are in the same sample category, and if it is determined that they are in the same sample category, the additional sample is analyzed. In the order table (see FIG. 4), the next order of the installed specimen, that is, the lower order of the installed specimen is registered. That is, when the operator selects the installed sample priority radio button 32 and the added sample and the installed sample are in the same sample category, the computer 110 of the operation unit 100 compares the installed sample with the added sample. First, the analysis unit 8 is caused to analyze.

  As described above, the computer 110 of the operation unit 100 displays the analysis priority setting item 31 on the start condition screen 30 in FIG. 2 on the display device 104 while the sample analysis is interrupted, and prompts the operator. On the other hand, the installed sample priority radio button 32 or the additional sample priority radio button 33 is selected. That is, by displaying such a screen, the computer 110 of the operation unit 100 allows the analysis unit 8 to add an additional sample to the analysis unit 8 first when the analysis unit 8 resumes the suspended analysis. An operator can select whether or not to analyze.

  By the way, in the automatic analyzer 1, there is a demand to change the analysis order for each sample if the degree of urgency of the sample (for example, urgent sample / general sample), that is, the same sample classification. For this reason, the automatic analyzer 1 has a function of changing the analysis order of each sample within the same sample category by the operation of the operator, and will be described below with reference to FIG. FIG. 5 is a “screen for changing the analysis order” displayed on the display device of the operation unit of the present embodiment, and is a diagram illustrating an example of a screen indicating the analysis order of each sample.

  The computer 110 of the operation unit 100 displays an “analysis order screen” 50, which is a screen indicating the analysis order of each sample, on the display device 104 so that the analysis order of the samples can be changed by an operation of the operator. On the analysis order screen 50, for each sample, an analysis order 51, a sample classification 52, a sample type 53, a position where the sample is installed on the sample disk 19 (simply referred to as “position” in FIG. 5) 54, a patient Items such as ID number (simply indicated as “patient ID” in the figure) 55 and sample analysis and reservation status (simply indicated as “situation” in FIG. 5) 56 are displayed. When the operator wants to change the analysis order of the samples, on the analysis order screen 50, the sample to be changed is selected using the input devices 102 and 103, and the analysis order of the selected samples is changed. The buttons 57 and 58 are used to move to a higher level or a lower level.

  When the operator presses the registration button 59, the computer 110 of the operation unit 100 registers the analysis order of each sample displayed on the analysis order screen in the analysis order table 40 (see FIG. 4). The computer 110 causes the analysis unit 8 to analyze each sample according to the registered analysis order table 40.

  Note that the computer 110 of the operation unit 100 can change the change of the analysis order of the samples for the samples in the same sample classification (for example, emergency sample / general sample). In addition, the computer 110 is configured so that the order of samples that are already being analyzed or samples that have been reserved (analysis scheduling) cannot be changed even if they are samples in the same sample category. In this way, since the analysis order of each sample can be changed as long as the samples are in the same sample category, for example, even in the same sample category (for example, emergency sample), more urgency such as emergency response It is possible to cause the analysis unit 8 to preferentially analyze a sample having a higher value than other samples in the same sample category.

  Differences between the technique of the present embodiment described above and the prior art will be described in comparison with FIGS. 6 and 7. FIG. 6 is a diagram for explaining a difference between the technique of the present embodiment and the conventional technique, and is a diagram showing a mode in which a specimen is placed on a sample disk. FIG. 7 is a diagram for explaining the analysis order when the conventional technique is applied and the analysis order when the technique of the present embodiment is applied. 6 to 7 are assumed to be the same sample category (showing the case of “emergency sample” as an example).

  As shown in FIG. 6, first, the sample A, the sample B, and the sample C are each installed in a position (hereinafter referred to as “empty position”) in the sample disk 19 that is vacant as a sample installation location. As shown in FIG. 7, the sample analysis order is set to the order of sample A, sample B, and sample C. The first sample installation in the sample disk 19 is described as “first installation” and is shown in FIG. The analysis is started from the sample A according to the analysis order set first, and after the analysis of the sample A is completed, the analysis is interrupted.

  Then, while the analysis is interrupted, the sample D, the sample E, and the sample F are added to the empty positions of the sample disk 19 and installed. The installation “while the analysis is interrupted in the middle” is described as “second installation” and is shown in FIG. After the samples D, E, and F are placed on the sample disk 19, the suspended analysis is resumed.

  In this case, the sample B and the sample C that have already been installed on the sample disk 19 before the analysis is not finished yet and before the analysis is interrupted on the way become the above-mentioned “installed samples”. On the other hand, while the analysis is interrupted halfway, the specimen D, specimen E, and specimen F additionally installed on the specimen disk 19 become “additional specimens”. In this case, the analysis order when the conventional technique is applied and the analysis order when the technique of the present embodiment is applied will be described below.

  When the prior art is applied, as shown in FIG. 7, the samples D, E, and F that are additional samples are analyzed because the samples B and C that are installed samples are analyzed. After it is done. When the conventional technique is applied, the analysis order of the samples is registered in the order in which the samples are set on the sample disk 19. Therefore, in the above example, the additional specimens D, E, and F are added to the installed specimens B and C that are additionally installed while the analysis has not been completed and the analysis is interrupted. Compared to the lower side. That is, the analysis order of the additional sample is later than that of the installed sample.

  On the other hand, when the technique of the present embodiment described above is applied, the computer 110 (see FIG. 1) of the operation unit 100 has not yet finished analyzing the samples D, E, and F that are additional samples. Compared to the specimens B and C, which are the installed specimens, they are registered at the highest level in the analysis order table (see FIG. 4). That is, the computer 110 causes the analysis unit 8 to analyze the additional samples D, E, and F earlier than the installed samples B and C that have not yet been analyzed. Thereby, the computer 22 of the analysis unit 8 of the automatic analyzer 1 analyzes the additional samples D, E, and F earlier than the installed samples B and C. As a result, the operator can know the analysis results of the additional samples D, E, and F earlier than the installed samples B and C.

  In the above-described embodiment, the sample placed on the sample disk is a specimen that is an object to be analyzed using a chemical reaction or the like, but the sample is not limited to this. The automatic analyzer of the present invention can be used for analysis of samples other than samples. Further, a member on which a plurality of specimens are installed for analysis is not limited to the sample disk of the present embodiment. Any member other than the sample disk can be used as long as it is a member on which the specimen (sample) can be set.

  As described above, the automatic analyzer 1 according to the present embodiment (see FIG. 1) has the sample disk 19 on which a plurality of samples are installed, and an analysis unit that analyzes the samples installed on the sample disk 19. 8 and an operation unit 100 for operating the analysis unit 8, and the computer 110 of the operation unit 100 performs the sample disk while the analysis of the sample placed on the sample disk 19 is interrupted. The analysis unit 8 first analyzes an additional sample that is a sample installed in addition to 19 compared to an installed sample that is a sample already installed on the sample disk 19 before the analysis is interrupted. It was. An additional sample that is more urgent than the installed sample can be preferentially analyzed, and the analysis result of the additional sample can be obtained in a shorter time.

  Further, in the automatic analyzer 1 of the present embodiment, the specimen is given information indicating the specimen classification, which is a classification for identifying the urgency of the specimen, according to the degree of urgency. When the additional sample and the installed sample are in the same sample category, the computer 110 of the unit 100 is configured to cause the analysis unit 8 to analyze the additional sample earlier than the installed sample. When the same sample classification (for example, an emergency sample) is already set as “installed sample” on the sample disc 19, a request for testing an emergency sample with higher urgency among emergency samples such as emergency response is made. In case of a sudden occurrence, the sample is added to the sample disk 19 as an additional sample, so that an additional sample (emergency sample) that is more urgent than the installed sample (emergency sample) is preferentially analyzed. Can be made.

  In the automatic analyzer 1 of the present embodiment, when the operation unit 100 causes the analysis unit 8 to resume the suspended analysis, the operation unit 100 causes the analysis unit 8 to analyze the additional sample earlier than the installed sample. It is assumed that the operator can select whether or not. In the case where the urgency of the installed sample and the additional sample is approximately the same, the installed sample can be preferentially analyzed compared to the additional sample by the operation of the operator.

  In the automatic analyzer 1 of the present embodiment, the operation unit 100 includes the display device 104 that displays the analysis order of each sample. The operator can visually recognize the analysis order of the samples displayed on the display device 104 and can operate the input device of the operation unit 100.

  Further, in the automatic analyzer 1 of the present embodiment, the operation unit 100 is configured to be able to change the analysis order of the samples as long as the samples are in the same sample category. Depending on the degree of urgency of the sample, the operator can change the analysis order for each sample.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. is there.

  The present invention is suitable for an automatic analyzer that automatically analyzes a sample (sample), and is particularly suitable for an analyzer that analyzes a plurality of samples (samples).
