Abstract

Provided is an automatic analysis apparatus which can obtain stable analysis results by stabilizing a constant-temperature bath and the temperature of a reaction liquid inside reaction containers. The automatic analysis apparatus (1) is equipped with a storage tank (10) for storing a liquid (L1) for controlling a temperature which is dividedly injected into the reaction containers (5) using devices (6) and (7) for divided injection, and a divided injection control section (15b) which is disposed between a cooling device and a reagent table (2) and cools piping, through which said cooling liquid is passed, to nearly the same degree as a reagent into which the liquid (L1) is dividedly injected, by passing the piping through the liquid (L1) stored in the storage tank (10) and, when there are vacant reaction containers (5) on a reaction table (4), into which no test substance nor reagent is injected, controls to dividedly inject the liquid (L1) into the vacant reaction containers (5) by using the devices (6) and (7) for divided injection.

Description

technical field [0001] The present invention relates to an automatic analysis device and a method for stabilizing a constant temperature bath of the automatic analysis device. Background technique [0002] Devices for automatically analyzing samples such as blood and body fluids are conventionally known to dispense samples and reagents into reaction containers to cause their chemical reactions at predetermined temperatures, and then optically analyze the reaction liquids. The chemical reaction of the sample and the reagent in the above-mentioned analysis takes place in the reaction table with a constant temperature bath, which is heated to close to body temperature, and in order to obtain stable analysis results, the temperature control of the constant temperature bath is extremely important. Therefore, it is conventional to heat the reagents kept cool in the reagent station and then distribute them into the reaction vessels, and to control the temperature of the thermostat ...
