Embodiment 1

[0112] Figure 6A A configuration example of the automatic analyzer 100 of the first embodiment is shown.

[0113] Figure 6A The illustrated automatic analyzer 100 is configured to roughly include a sample disk mechanism 1, a sample supply dispensing mechanism 2 including a sample nozzle 27, a reaction disk 3, a reagent disk mechanism 5, and a reagent aspirating mechanism including a reagent nozzle 28. 7. And the computer 19 that controls the whole through the interface 23.

[0114] A plurality of sample cells 25 are arranged in the sample disk mechanism 1 . Here, a sample tray mechanism is described as an example of a sample storage unit mounted on a disc-shaped mechanism unit. However, as other forms of the sample storage unit mechanism, sample racks or sample holders commonly used in analysis devices may also be used. Keeper-like way. In addition, the sample mentioned here refers to the liquid to be tested for the reaction in the reaction pool 4 in the reaction disk 3,...

Embodiment 2

[0152] In this embodiment, a modified example of the above-mentioned Embodiment 1 is shown. In Embodiment 2, an example of configuring the automatic analyzer 200 was shown as an independent mechanism of the antifouling film forming mechanism and the antifouling film peeling mechanism. In the present embodiment, another mechanism can also serve as the antifouling film forming mechanism or the antifouling film peeling mechanism. Thereby, space saving of the automatic analyzer 200 can be realized.

[0153] Figure 10 The structure of the automatic analyzer 200 of this embodiment is shown. exist Figure 10 In the shown configuration, the same reference numerals are assigned to the same contents as those described in the first embodiment with reference to FIG. 6 , and their descriptions are omitted.

[0154] In this embodiment, instead of the paint agent supply / recovery unit 33 in Embodiment 1, the paint agent is supplied in a part of the reagent container 331 of the reagent cont...

Abstract

In order to inhibit air bubble adhesion in reaction cells and enable antifouling of the reaction cells using a coating agent in only specific analysis items, an automatic analysis device is configured which is provided with: a sample disk mechanism; a reaction disk for accommodating the reaction cells; reagent disk mechanisms; a sample-supplying dispensation mechanism which supplies samples to the reaction cells; a reagent-supplying dispensation mechanism which supplies prescribed amounts of reagents to the reaction cells; a detection unit which irradiates, with light, the reaction cells having, formed therein, mixed solutions of the samples and the reagents, and detects the light transmitted through the reaction cells to detect the optical characteristics of the mixed solutions; an antifouling-film formation mechanism which supplies an antifouling solution to the reaction cells to form antifouling films on the inner wall surfaces of the reaction cells; and an antifouling-film removal mechanism which supplies a removal solution to the reaction cells to remove the antifouling films from the inner wall surfaces of the reaction cells.

Description

technical field [0001] The present invention relates to a reaction cell for an automatic analyzer, an automatic analyzer equipped with the reaction cell, and an analysis method using the automatic analyzer. Background technique [0002] In the clinical examination of medical diagnosis, biochemical analysis and immunological analysis of proteins, sugars, lipids, enzymes, hormones, inorganic ions, disease markers, etc. are performed on biological samples such as blood and urine. In clinical examinations, it is necessary to process a plurality of analysis items with high reliability and high speed, and therefore most of the processes are performed by an automatic analysis device. Conventionally, a biochemical analyzer is known as an automatic analyzer that mixes a desired reagent with a sample such as serum, reacts, and measures the absorbance of the reaction solution to perform biochemical analysis. [0003] For example, Japanese Patent No. 4584878 (Patent Document 1) describ...
