Problems solved by technology

[0004] However, the stirring mechanism of the sample analyzer described in US Patent Application Publication No. 2002-0132353 needs to have a structure that allows the reagent container to rotate on its own, which brings about the disadvantage of complex instrument structure

Embodiment Construction

[0063] The configuration of the sample analyzer of the present invention will be described in detail below with reference to the drawings.

[0064] First, refer to Figure 1 to Figure 12 , Figure 15 and Figure 18 , the configuration of the analyzer 1 according to one embodiment of the present invention will be described.

[0065] The analyzer 1 according to one embodiment of the present invention is a device for performing various tests such as hepatitis B, hepatitis C, tumor markers, and thyroid hormone using samples such as blood. This analyzer 1 binds the magnetic particles (R2 reagent) to the capture antibody (R1 reagent) that binds to the antigen contained in the sample such as blood to be tested, and then attracts the bound (bound) antigen, capture antibody and magnetic particles to the A BF (Bound Free) separator 11 (refer to figure 1 and figure 2 ) magnetic block (not shown), remove the R1 reagent containing the unreacted (Free) capture antibody. Let the antig...

Abstract

A sample analyzer comprising: a reagent container holder, configured to rotate around a rotational axis and to hold a reagent container containing a reagent; a reagent aspirator for aspirating, at a reagent aspirating position, the reagent from the reagent container held by the reagent container holder; an analysis section for analyzing a measurement sample prepared from the reagent aspirated by the reagent aspirator and a sample; and a controller for controlling: the reagent container holder to rotate and thereby transport the reagent container to the reagent aspirating position, the reagent aspirator to aspirate the reagent from the reagent container, and the reagent container holder to accelerate and decelerate alternately while being rotated is disclosed. A sample analyzing method is also disclosed.

Description

Technical field: [0001] The invention relates to a sample analyzer and a sample analysis method, in particular to a sample analyzer with a reagent stirring mechanism and a sample analysis method. Background technique: [0002] A sample analyzer having a mechanism for stirring reagents has been known in the past (see, for example, US Patent Application Publication No. 2002-0132353). [0003] The sample analyzer described in U.S. Patent Application Publication No. 2002-0132353 has a stirring mechanism. The stirring mechanism makes the reagent container revolve around the rotation center of the turntable by rotating the turntable on which the reagent container is placed in an annular shape, and at the same time makes the reagent container rotate on the turntable. In this way, the tiny particles contained in the reagent are stirred evenly. [0004] However, the stirring mechanism of the sample analyzer described in US Patent Application Publication No. 2002-0132353 needs a stru...
