Title
(EN) AUTOMATIC ANALYSIS DEVICE
(FR) DISPOSITIF D'ANALYSE AUTOMATIQUE
(JA) 自動分析装置
Abstract
(EN) When washing the inside of a reactor vessel which is used repeatedly, a rough suction is performed before suctioning with a washing tip; however, unwanted washing liquid may remain depending on the amount of liquid remaining after the rough suction and the position of the washing tip and individual differences in the sizes thereof, and as a result, there has been a danger that remaining washing liquid may affect analysis results. The present invention provides an automatic analysis device for analyzing a sample using light, wherein the automatic analysis device is characterized in that: a washing mechanism comprises a washing liquid supply nozzle that supplies washing liquid to a reactor vessel after analysis, a washing liquid suction nozzle that suctions the supplied washing liquid, a washing tip provided to the bottom end of the washing liquid suction nozzle, and a rough suction nozzle that suctions, in advance, a liquid within the reactor vessel before suctioning with the washing tip; and after the rough suction, liquid is caused to remain so that the bottom surface of the reactor vessel is not exposed.
(FR) Lors du lavage de l'intérieur d'une cuve de réacteur qui est utilisée de façon répétée, une aspiration grossière est effectuée avant l'aspiration avec une pointe de lavage; cependant, du liquide de lavage indésirable peut rester en fonction de la quantité de liquide restant après l'aspiration grossière et la position de la pointe de lavage et des différences individuelles dans leurs tailles, et, par conséquent, il y a un danger que le liquide de lavage restant puisse affecter des résultats d'analyse. La présente invention concerne un dispositif d'analyse automatique pour analyser un échantillon à l'aide de lumière, le dispositif d'analyse automatique étant caractérisé en ce que: un mécanisme de lavage comprend une buse d'alimentation en liquide de lavage qui fournit un liquide de lavage à un récipient de réacteur après analyse, une buse d'aspiration de liquide de lavage qui aspire le liquide de lavage fourni, une pointe de lavage disposée sur l'extrémité inférieure de la buse d'aspiration de liquide de lavage, et une buse d'aspiration grossière qui aspire, à l'avance, un liquide à l'intérieur de la cuve de réacteur avant l'aspiration avec la pointe de lavage; et après l'aspiration grossière, du liquide est amené à rester de telle sorte que la surface inférieure de la cuve de réacteur n'est pas exposée.
(JA) 繰り返し使用する反応容器内を洗浄する際に、洗浄チップで吸引する前に粗吸いを行うが、粗吸い後の液量と洗浄チップの位置、大きさの個体差によっては洗浄液が残ってしまい、分析結果に影響を与えてしまうおそれがあった。 光を用いて試料を分析する自動分析装置であって、洗浄機構が、分析後の反応容器に洗浄液を供給する洗浄液供給ノズルと、供給された洗浄液を吸引する洗浄液吸引ノズルと、洗浄液吸引ノズルの下端に設けられた洗浄チップと、洗浄チップで吸引する前に予め反応容器内の液体を吸引する粗吸いノズルとを備え、粗吸い後に、反応容器の底面が露出しないように液体を残すことを特徴とする自動分析装置を提供する。
