Embodiment Construction
[0027] Hereinafter, examples of the present invention will be described in detail. In addition, although the embodiments of the present invention mainly focus on immunoassay devices, the present invention can be applied to all automatic analyzers. For example, the present invention can also be applied to biochemical automatic analysis devices, genetic analysis devices, quality analysis devices, and bacteria inspection devices.
[0028] In addition, the embodiment of the present invention is effective for liquids separated by differences in specific gravity and liquids containing solids such as magnetic particles, and can be applied to all liquids used when a user analyzes using an automatic analyzer.
[0029] figure 1 It is a schematic diagram of the automatic analysis apparatus of an Example. The automatic analysis device 1 is provided with: an analysis unit 101 for performing an analysis operation; a control unit 102 for controlling the overall operation of the device; an ...

Provided is a high-performance automatic analysis technique in which a liquid inside a reaction vessel and a subsequently added liquid are prevented from locally coming into contact at high concentrations, and in which the frequency of device failure is low. This automatic analyzer 1 comprises a reaction vessel disc 120 that holds a reaction vessel 116, a stirring mechanism 124 that stirs a liquidinside the reaction vessel 116 in a non-contact manner, a conveying mechanism 125 that conveys the reaction vessel 116 between the reaction vessel disc 120 and the stirring mechanism 124, a reagent disc 122 that holds a reagent vessel 121, and a reagent dispensing mechanism 123 for suctioning and discharging a reagent inside the reagent vessel 121. The stirring mechanism 124 is provided at a position at which the reagent dispensing mechanism 123 discharges the reagent. The reagent dispensing mechanism 123 discharges the reagent, which has been suctioned from the reagent vessel 121, into the reaction vessel 116 disposed in the stirring mechanism 124.
Description
technical field [0001] The present invention relates to an automatic analysis device and analysis method for analyzing biological samples. Background technique [0002] The automatic analysis device contributes to prompt and efficient clinical examination work by automating a part of the procedures of the examination of the specimen. A general automatic analyzer includes a dispensing mechanism for dispensing a predetermined amount of a sample, reagent, etc. into a reaction container, and a stirring mechanism for stirring the sample, reagent, etc. in the reaction container. [0003] Previously, in the case of an automatic analyzer that discharges a plurality of solutions to a reaction vessel and stirs them, by one discharge action, the entire amount of the different solutions is then added to the reaction vessel to which the discharged solutions have been added, followed by stirring . For example, the automatic analyzer first discharges the sample into the reaction containe...
