Embodiment Construction

[0038] Embodiments of the present invention will be described below based on the drawings.

[0039] figure 1 Shows a top view of the automated analyzer.

[0040] The automatic analysis device is composed of an analysis unit 10 and a buffer unit 11 .

[0041] The analysis unit 10 side is equipped with a reagent transport mechanism 27 and a reagent discharge and storage mechanism 26, and the reagent transport mechanism 27 transports the reagent container 12 transferred from the reagent storage box A28, the reagent storage box B29, and the buffer unit 11 to the reagent storage unit. The reagent storage mechanism 26 discharges the reagent container 12 on the analysis unit 10 side from the box A28 or the reagent storage box B29. On the side of the buffer unit 11, there are provided a replenishment reagent storage box 20 for temporarily holding a replenishment reagent, and a reagent discharge mechanism 25 for discharging a reagent container.

[0042] Using this device, the proced...

Abstract

The invention provides an automatic analysis device. Unlike the reagent storage mechanism of the conventional analysis unit having a cold storage function, the reagent storage mechanism for replacement does not have a cold storage function, and in this case, higher reagent management is required. By managing the placement elapsed time of the reagent container of the reagent storage mechanism (2) for replacement, the placement elapsed time of the reagent and the placement allowable limit value stored as one analysis parameter for each analysis item In comparison, by determining whether or not the elapsed placement time exceeds the placement allowable limit value, deterioration of the reagent can be prevented, and the reagent container can be automatically supplied to the analysis unit for measurement.

Description

technical field [0001] The present invention relates to an automatic analysis device for analyzing samples such as blood and urine, and to a device for replacing reagent containers. Background technique [0002] Automatic analyzers that analyze samples such as blood and urine increase the number of samples to be processed and the number of measurement items, and the consumption of reagents increases, thereby increasing the chances of replacing reagent containers. On the other hand, in order to reduce costs such as personnel costs, it is necessary to reduce operator work as much as possible, and simplification of reagent container replacement work is desired. [0003] In addition, since the sample processing speed of the automatic analyzer is also increased, it is desired to minimize the interruption of the analysis operation by not stopping the operation of the device during the reagent replacement operation. [0004] For example, in Patent Document 1, unlike the reagent st...
