Automatic analysis device

Abstract

Provided is an automatic analysis device which, when an urgent sample is put into the automatic analysis device, can rapidly and efficiently carry the urgent sample to the analysis device without interchanging racks and start the analysis of the urgent sample. The present invention is characterized in that, in a determination as to whether or not a rack put into an automatic analysis device by a user is transferred to an analysis unit, a sample present in a route from a buffer to a sample split position in the analysis unit is identified, and the number of items in which suction with a nozzle has not been completed among analysis items requested for the sample is managed, by performing control for carrying a next rack from the buffer into the analysis unit when the number of items falls to a given number or less, the number of analysis items requested for samples that are waiting for analysis in the analysis unit can be always limited to the given number or less, and even when a new urgent sample is put in, the time elapsed until the measurement result of the urgent sample is outputted is reduced.

Description

technical field [0001] The present invention relates to an automatic analyzer for qualitative and quantitative analysis of biological samples such as blood or urine. Background technique [0002] In an automatic analyzer including a unit that sets a sample on a rack or the like and transports it to an analysis unit, it is desirable to start analysis prior to an ordinary patient sample when an emergency sample is set in the device. Therefore, it is known to have a buffer section for evacuating samples waiting for analysis, and when a rack mounted with an emergency sample is loaded, the samples waiting for analysis are evacuated to the buffer section, and the emergency sample rack can exceed the inside of the buffer section. The rack preferentially starts the analysis of the automatic analysis device. [0003] When the distance from the buffer unit to the sample dispensing position is long, usually a plurality of racks are transported along the transport path from the buffer ...

Problems solved by technology

Therefore, even if the number of racks loaded into the analysis unit is limited, the time required until the end of dispensing may not be shortened as a result depending on the number of items requested from the sample in the rack.

[0010] In addition, in the case of limiting the number of imported racks, there may be a large delay in the report of the results of the urgent racks required for the prompt report of the analysis results.
