Description

  The present invention relates to an automatic analyzer that performs qualitative and quantitative analysis of biological samples such as blood and urine, and more particularly to an automatic analyzer that has a function of continuously processing a plurality of biological samples.

  In automatic analyzers that perform qualitative and quantitative analysis of biological samples such as blood and urine, specimens that have been processed in the automatic analyzer are placed in the storage unit in the order in which the processing is completed in the apparatus or in the order in which they are installed It was stored and could not be classified according to the next processing content of the specimen.

  In an analyzer that connects multiple analysis modules via a sample transport line, the analysis items differ for each sample, so that the sample that was input earlier in the sample transport process may overtake the sample that was input later. In some cases, the order in which the specimens were loaded and the order in which the specimens were stored were different. In this case, the operator needs to identify the sample by looking at the identification code attached to the sample. When analyzing a sample stored in the storage unit with another analyzer, it is difficult to determine at a glance which sample should be taken out. For this reason, Patent Document 1 describes that a plurality of sample storage units are provided, and control is performed so that rack numbers are distributed so as to be continuous and stored in a plurality of storage units.
