また、この発明の第２の形態は、試料及び試薬を反応容器に分注することにより反応溶液を生成し、該反応溶液の成分を分析する自動分析装置において、前記分析した後の前記反応溶液、又は、前記反応容器を洗浄した後の洗浄液である廃液が入れられた前記反応容器を洗浄位置に移動させる駆動部と、先端部に吸引口が設けられ、前記反応容器内から外部に前記廃液を排出するための吸引管と、先端部に供給口が設けられ、外部から前記反応容器内に洗浄液を供給するための供給管と、前記吸引口を、前記洗浄位置に移動された前記反応容器の上方位置と前記反応容器内の底部近傍位置との間を往復移動させるように、前記吸引管を移動させる吸引管駆動部と、前記底部近傍位置に移動させた前記吸引口から前記廃液を吸い出す吸引処理部と、前記供給口を、前記廃液が吸い出された後の前記反応容器の上方位置と前記吸い出される前の前記廃液の液面に上方から近い液面近傍位置との間を往復移動させるように、前記供給管を移動させる供給管駆動部と、前記液面近傍位置に移動させた前記供給口へ前記洗浄液を供給する供給処理部と、を有することを特徴とする自動分析装置である。 In order to solve the above-mentioned problems, the present invention has focused on supplying a cleaning liquid having an amount corresponding to the position of the liquid level of the waste liquid.
Specifically, according to the first aspect of the present invention, in the automatic analyzer that generates a reaction solution by dispensing a sample and a reagent into a reaction vessel and analyzes the components of the reaction solution, the analysis is performed after the analysis. There is a suction mechanism and a supply port for discharging the reaction solution or the waste solution, which is a cleaning solution after washing the reaction vessel, from the inside of the reaction vessel, and the waste solution is discharged from the supply port. A supply mechanism for moving to a position in the vicinity of the liquid level close to the liquid level of the previous waste liquid from above and supplying the cleaning liquid from the outside into the reaction vessel through the moved supply port. Automatic analyzer.
The second embodiment of the present invention is a method for producing a reaction solution by dispensing a sample and a reagent into a reaction vessel, and analyzing the reaction solution after the analysis in an automatic analyzer for analyzing the components of the reaction solution. Alternatively, a drive unit that moves the reaction vessel in which a waste solution, which is a washing solution after washing the reaction vessel, is moved to a washing position, and a suction port are provided at the tip, and the waste solution is provided from the reaction vessel to the outside A suction tube for discharging the liquid, a supply port at the tip, a supply tube for supplying a cleaning liquid into the reaction vessel from the outside, and the reaction vessel in which the suction port has been moved to the washing position The waste liquid is sucked out from the suction pipe drive unit for moving the suction pipe so as to reciprocate between the position above the bottom and the position near the bottom in the reaction vessel, and the suction port moved to the position near the bottom. Suction processor , Said supply opening, between the liquid surface near the position close to the above the liquid surface of the front of the waste liquid in which the waste liquid is sucked said an upper position of the reaction vessel after being sucked out so as to reciprocate An automatic analyzer comprising: a supply pipe drive unit that moves the supply pipe; and a supply processing unit that supplies the cleaning liquid to the supply port moved to a position near the liquid surface.
