An automatic analyzer includes a storage unit for storing operation information information about usage histories of expendable supplies provided for the analysis, and an analysis-ID control unit giving an ID to the analysis, the analysis ID being used as information for identifying the analysis to derive a calibration curve. Data stored in the storage unit is organized along the same time axis both in the order of samples subjected to the analysis and inspection, and in the order of analysis items, so that the data is output in a total data display area. The data is organized from the viewpoint of an analysis process of an analysis item of each sample. By use of information used to identify an influence range based on a kind of an abnormal state, which is stored beforehand, a judgment is made as to whether or not it is necessary to perform reinspection.

Automatic analyzer

Remote maintenance system

An automated analyzer device has a main conveyance line capable of conveying a sample rack holding a sample, a plurality of analysis units arranged along the main conveyance line, a rack supplying device for supplying the sample rack to the main conveyance line and a rack housing device for housing the sample rack conveyed by the main conveyance line. The automated analyzer includes a controller for confirming that there is no sample rack on the main conveyance line before the main conveyance line receives the sample rack from the rack supplying device. The controller controls operation of the main conveyance line so as to convey the sample rack received from the rack supplying device by the main conveyance line to a position corresponding to a specific one of the plurality of analysis units by which the sample rack is to be received without stopping.

Method of conveying sample rack and automated analyzer in which sample rack is conveyed

A system setup for a sample analysis system having a plurality of analysis units placed along a main conveyor line prior to its analysis operation. The system setup includes setup of analysis units in combination with different types of reagent supply units, setup of analysis routes as to whether it is a stationary type or an automatic type, and setup of analysis items for each analysis unit as to which analysis item should be assigned to which analysis unit having which reagent supply type. These settings are executed through monitoring of setup screens displayed on a screen display unit, and the contents of such a setting are stored and registered in a memory of the controller.
