Embodiment 1

[0036] Examples of the present invention will be described using an automatic analyzer using a set of reagent bottles in one cassette.

[0037] figure 1 It is a schematic configuration diagram of an automatic analyzer according to Example 1 to which the present invention is applied. figure 1 In the embodiment, a plurality of reaction vessels 5 are arranged on the circumference of the reaction disk 9 on the frame body 21 .

[0038] On the reagent disk 15, a plurality of reagent cartridges 16 can be respectively arranged on the circumference. A maximum of three reagents (first reagent to third reagent) can be accommodated in one reagent cartridge 16 .

[0039] A transport mechanism 3 is provided near the reaction disk 9, and the transport mechanism 3 moves the stage 1 on which the sample container 2 is mounted. Guide rails 25 and 26 are arranged on the reagent disk 15 , and a reagent detector 11 , a reagent unsealing mechanism 12 , and a reagent box conveying mechanism 14 are...

Embodiment 2

[0082] Next, Example 2 of the present invention will be described.

[0083] Embodiment 2 of the present invention is in figure 1 The device structure shown with image 3 The processing procedure shown is the same as that of Embodiment 1, and thus detailed description thereof will be omitted.

[0084] Embodiment 2 of the present invention is used in image 3An example of the case where the control unit 33 performs the time-dependent change of the calculated value and the precision management of the reagent and the device for the calibration check value calculated in Steps 9 and 10.

[0085] In Embodiment 1, it is described that a plurality of fluctuation parameters 38 are stored, and information on reagent batches that have passed a certain period of time is deleted, but in Embodiment 2, by storing a plurality of values ​​of the fluctuation parameters 38 for a long time, and by real-time (Each batch) is displayed so that the user can easily confirm the change in the quality ...

Abstract

The invention provides an automatic analysis device which is capable of appropriately setting analysis parameters on which different reagent properties are reflected for each reagent lot. In a storage unit of the automatic analysis device, an analysis parameter (35) constituted of a fixed parameter (37) and a fluctuating parameter (38) is stored, and the fixed parameter (37) includes a reagent dispensed amount, a sample dispensed amount, a measurement wavelength, and the like, which are major items of a reagent measurement, and selects a parameter to be used from an item code and a bottle code indicated on a reagent bottle (36). The fluctuating parameter (38) includes a linearity check value, a prozone check value, a reaction limit absorbance, a technical limit, a first standard solution absorbance, a variation permissible absorbance, and the like related to a check of a sample measurement result. The fluctuating parameter (38) is provided with a plurality of versions, and a control unit of the automatic analysis device reads barcode information of the reagent bottle and adopts the fluctuating parameter of a corresponding version with the item code, the bottle code, and reagent lot information as keys.

Description

technical field [0001] The present invention relates to an automatic analyzer for qualitative and quantitative analysis of biological samples such as blood and urine. Background technique [0002] For reagents used in automatic analyzers for clinical examinations, the optimal conditions for measurement wavelength, reagent volume, specimen volume, analysis method, etc. are determined through experiments during reagent development. The determined analysis parameters are applied for and registered as the basic parameters of the Pharmaceutical Law. The analytical parameters and prescriptions of these reagents cannot be easily changed after application as the basic parameters of the Pharmacy Act. [0003] However, in the production of reagents, the amount that can be produced at one time is determined by using a reaction pot. The production volume is managed in batches, and a certain amount of reagents are filled into reagent bottles and sold. In this case, the batch informati...
