Problems solved by technology

However, when a standard sample is taken from a sample container that is repeatedly used after cleaning and measured, the measurement accuracy of the standard sample decreases, and an accurate calibration curve may not be calculated, and the concentration may be calculated using an incorrect calibration curve. May cause all measurements to be incorrect

Embodiment 1

[0023] figure 1 It is a diagram showing the overall structure of the automatic analyzer of the first embodiment. The automatic analysis device of the present invention has: the sample plate 1 of the sampling container that fixedly puts the sampling container of the living body source sample, and the sampling sample plate (also called sample table) 2, the first reagent disc 3 and the second reagent disc 4 that fix the plurality of sample containers that are put into the reagent, the sample that will be dispensed from the sample container of the sample disc 2 and the sample from the first reagent disc. The reagents dispensed from the reagent containers of the reagent disc and the second reagent disc are put into the reaction tank to make the reaction disc 5 react.

[0024] For example, 100 sampling containers 11 in two rows are fixed on the sample tray 1, and are fed step by step at a predetermined speed. A predetermined amount of the sample in the sampling container 11 is asp...

Embodiment 2

[0031] A second embodiment of the present invention will be described below.

[0032] image 3It is a figure showing the overall structure of the automatic analyzer of the second embodiment. The automatic analysis device of the present invention has: a sample disc 101 for holding a sampling container 111 containing a sample from a living body; , the first reagent disc 104 and the second reagent disc 105 that fix the plurality of reagent containers in which the reagents are placed, the samples dispensed from the sample containers on the dispensing sample transport line 102 and the samples from the first reagent disc, the second reagent disc The reagents dispensed from the reagent containers of the second reagent disc are placed in the reaction tank and reacted in the reaction disc 106 . In addition, a plurality of analysis units 181 including the first tray 104 , the second tray 105 , and the reaction tray 106 may be arranged along the dispensing sample transfer line 102 . T...

Abstract

An object of the present invention is to achieve analysis with high precision using an automatic analyzer by preventing the contamination of a sample vessel from influencing the precision of analysis, the automatic analyzer using a sample pipetted into the sample vessel to perform the analysis, the sample vessel being repeatedly cleaned and used. The automatic analyzer of the invention uses a sample pipetted into a sample vessel to perform analysis, the sample vessel being repeatedly cleaned and used. In order to prevent the contamination of the sample vessel, which is caused by the measurement of general biologically-derived samples, from influencing the analysis, the automatic analyzer uses a specified sample vessel to measure standard solution so that the calibration of each analysis item is carried out, and the automatic analyzer does not use the sample vessel in question for analysis of other biologically-derived samples.

Description

technical field [0001] The present invention relates to an automatic analysis device for analyzing components of samples derived from living organisms such as blood and urine, and more particularly to an automatic analysis device having a sample container storage mechanism capable of placing a plurality of sample containers for storing samples. Background technique [0002] An automatic analysis device for analyzing a sample derived from a living body includes: a device for performing analysis by directly dispensing a sample from a sample container loaded into the device into a reaction container; A device that separates a sample container and dispenses a sample from the sample container to a reaction container for analysis. The device for directly dispensing the sample from the loaded sample container to the reaction container has the advantage of a simple structure of the device. On the other hand, although the device for dispensing samples from the placed sample containe...
