Description

  The present invention relates to an automatic analyzer that measures and analyzes components of a sample such as serum.

  In recent years, in the field of automatic analysis, a semi-random access method has been developed, and future trends are drawing attention. The semi-random access method is equipped with multiple reaction lines for analyzing the components of samples such as serum and can measure the measurement items for multiple reaction lines simultaneously. All measurement items can be measured with minimum sampling by assigning to multiple reaction lines. Therefore, the rapid processing is expected as a very useful method obtained with the simplification of the structure by realizing the sharing of one system such as the turntable mechanism and the photometry system using the pair reaction tubes.

  By the way, there is a possibility that the components of the reagents may be slightly different from lot to lot, and even if the nominal components are the same, there is also a problem that the elapsed time from the production time varies. Every one is strictly managed. Therefore, since the reagent bottles to be used differ depending on the reaction line, it is necessary to analyze using a calibration curve separately for each reaction line.

  For this reason, it is necessary to manage the measurement analysis process not only with items but also with the distinction of reaction lines within the automatic analyzer. For this reason, even if the analysis results are compiled as a report, measurement related to the same measurement item is required. The result was to be performed by distinguishing the reaction lines. However, this only makes the report cumbersome and is not preferable.

  In the above-described conventional semi-random access type automatic analyzer, it is desirable that at least reaction lines are distinguished and handled separately for the same measurement item, and the measurement result report is output as for one measurement item. Moreover, when a trouble occurs, it is necessary to be able to determine which reaction line the measurement result is obtained so that the reaction line in which the trouble has occurred can be traced from the measurement result.

  An object of the present invention is to provide an automatic analyzer that can optimally selectively use a method for discriminating only measurement items and a method for discriminating not only measurement items but also reaction lines in accordance with each process. is there.

A first aspect of the present invention is a semi-random access type automatic analyzer equipped with a plurality of reaction lines for component analysis of a sample and capable of measuring any measurement item in a common photometry system in two or more reaction lines. The measurement item assigned to each reaction line is managed by identification name information that identifies each measurement item in combination with the reaction line.
According to a second aspect of the present invention, a reagent probe corresponding to each of a plurality of reaction lines for component analysis of a sample, a common photometry system for performing measurement in the plurality of reaction lines, and a measurement assigned to each reaction line Management means for managing items by identification name information that identifies each measurement item in combination with the reaction line.

  According to the present invention, a method for discriminating only measurement items and a method for discriminating not only measurement items but also reaction lines can be optimally used according to each processing step.

  Hereinafter, an automatic analyzer according to the present invention will be described with reference to the drawings according to a preferred embodiment. FIG. 1 is a block diagram showing a configuration of an automatic analyzer according to the present embodiment. This automatic analyzer is configured as follows with the control unit 15 as a center. Here, please refer to the operation flow shown in FIG. 2 together with FIG. First, the measurement system 12 is configured to support the sub-random access method, and is equipped with two reaction lines for analyzing components of a sample such as serum using paired reaction tubes. Some measurement items can be measured using either of the two lines. A sample probe for sample dispensing, a reagent storage, a reagent probe for reagent dispensing, etc. are dedicated to these two reaction lines, respectively, while a photometric unit is also provided.

  The input means 27 is provided for the operator to input (request) measurement items by various operations. The measurement items input from the input means 27 are stored in the request information storage means 17 via the request registration means 16. be registered. A measurement item condition setting means 19 is provided for the operator to set various conditions relating to the measurement items, and the conditions set by the means 19 are stored in the measurement item condition storage means 20.

  The measurement item sorting unit 18 efficiently converts the measurement items registered in the request information storage unit 17 according to various conditions stored in the measurement item condition storage unit 20 and unavoidable predetermined conditions such as preventing contamination. It is provided to perform the process of assigning the requested measurement item to each reaction line so that the process is performed properly.

  In accordance with the allocation of the measurement item sorting means 18, the sequencer 11 controls the measurement system 12 to advance the measurement process. The measurement result measured here is analyzed by the quality control / result display means 24 based on the calibration curve for each reaction line. The analyzed measurement result is displayed and output on the display device 28 in a state where the measurement item and the reaction line can be distinguished.

  Further, the measurement result is stored in the measurement result storage means 26 via the measurement result storage means 25, and the measurement result report means 29 distinguishes only the measurement items and does not distinguish the reaction lines. The data is edited, transferred to the host computer 31 and displayed as a report, and also transferred to the printing means 30 to be printed out as a report on a predetermined sheet.

  By the way, as described above, the components of the reagent may be slightly different from lot to lot, and even if the nominal components are the same, there is also a problem that the elapsed time from the production time varies. The processing needs to be performed by distinguishing not only the measurement items but also the reaction lines including the calibration curve used for the analysis of the measurement results. However, on the other hand, the measurement results of the same measurement item need only be able to distinguish between the measurement items as the final report, and there is no need to distinguish the reaction lines. Furthermore, it is necessary to display the measurement result in a state where not only the measurement item but also the reaction line can be distinguished so that the reaction line where the trouble has occurred can be known.

  Depending on the situation, it is preferable to use a method that distinguishes only the measurement items and a method that distinguishes not only the measurement items but also the reaction line in the measurement item and measurement result management system. Is realized by multiplexing management information as shown in FIG. The former method should be managed by receiving and registering a request for a measurement item from the host computer 31, finally editing the measurement result into a report, transferring it to the host computer 31, displaying it, and printing it out. is there. On the other hand, the latter method should be managed by assigning measurement items to reaction lines, processing for analyzing measurement results using a calibration curve, and measurement analyzed on the display device 28 to distinguish the reaction lines where trouble occurred. There is a process to display the results.

  Here, as shown in FIG. 3, two items A and B are requested for the patient (1), and four items A, B, C, and D are requested for the patient (2). A case is assumed in which two items A and B, which have a large number of requests, are set in a state where they can be measured in either of two reaction lines. In this assumption, management information is assembled as shown in FIG. In other words, identification name information for uniquely identifying each requested measurement item in combination with a reaction line that can measure each measurement item, and a combination for identifying each measurement item without identifying a reaction line Name information and slave information indicating the presence or absence of a secondary reaction line with respect to the main reaction line for each measurement item are set.

  Using such management information, for the patient (1), the two items A and B are separately assigned to two reaction lines, and for the patient (2), two items A and B are assigned. By assigning items to one reaction line and assigning two items C and D to the other reaction line, the number of samplings can be made efficient.

  In addition, for the process of accepting and registering the request for the measurement item from the host computer 31, the process of finally editing the measurement result into a report, transferring it to the host computer 31 to display it, and printing it out, use binding name information. Thus, it is not necessary to distinguish only the measurement items and the reaction lines, and the operator of the host computer 31 can receive a request for measurement items and a report of measurement results without being aware of the difference in the reaction lines.

  In addition, in the process of allocating measurement items to reaction lines, the process of analyzing measurement results using a calibration curve, and the process of displaying the measurement results analyzed on the display device 28 in order to distinguish the reaction lines where trouble has occurred, By using the information, not only the measurement items but also the reaction lines can be distinguished, the calibration curve can be distinguished from the reaction line, and the troubled reaction line can be identified.

  As described above, according to the present embodiment, it is possible to properly use only according to various processes, whether to distinguish only measurement items or to distinguish measurement items by matching reaction lines.

  The present invention is not limited to the embodiments described above, and can be implemented with various modifications. For example, the identification name information may be information that directly describes the measurement item name and the reaction line number, such as ALT + line 1.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
