Description
【０００１】[0001]
本考案は、試料分注用ノズル，試薬分注用ノズル，前記両ノズルを各々洗浄す る洗浄槽を備えた自動分析装置に関する。 The present invention relates to an automatic analyzer having a sample dispensing nozzle, a reagent dispensing nozzle, and a cleaning tank for cleaning each of the nozzles.
【０００２】[0002]
従来、ノズルの洗浄は、洗浄槽にノズルを移動させ、外部より水をかける方法 とノズル内部に水を通し行なっている。また、超音波洗浄においては、ノズルに 一体に設けられた液面センサの汚れに対し、特開昭61−42805 号が提案されてい る。液面センサが侵漬される洗浄槽底部に振動子を設けることにより、洗浄を行 なうものである。 Conventionally, nozzle cleaning is performed by moving the nozzle to a cleaning tank and applying water from the outside or by passing water inside the nozzle. Further, in ultrasonic cleaning, Japanese Patent Application Laid-Open No. 61-42805 has been proposed for the contamination of a liquid level sensor provided integrally with a nozzle. Cleaning is performed by providing a vibrator at the bottom of the cleaning tank where the liquid level sensor is immersed.
【０００３】[0003]
自動分析装置では、多種多品の試料，試薬が用いられている。また、この内、 品種により、水のみではノズルの洗浄が不十分であり、測定回数の増加に伴い、 コンタミネーションの発生が増加し、誤検出の原因となっている。本考案は、以 上の問題に対し、ノズルの洗浄度を高くし、誤検出防止を提供することを目的と している。 A wide variety of samples and reagents are used in automatic analyzers. In addition, among these, depending on the product type, cleaning of the nozzle is not enough with water alone, and as the number of measurements increases, the occurrence of contamination increases, which is a cause of erroneous detection. The present invention aims to solve the above problems by increasing the cleanliness of the nozzle and preventing false detection.
【０００４】[0004]
前記目的を達成するため、試料分注用ノズル，試薬分注用ノズル、及び前記両 ノズルを各々洗浄する洗浄槽の内、少なくとも一つに振動子を設けたことを特徴 としている。 In order to achieve the above object, a vibrator is provided in at least one of a sample dispensing nozzle, a reagent dispensing nozzle, and a cleaning tank for cleaning both nozzles.
【０００５】[0005]
試料分注用ノズル，試薬分注用ノズルの洗浄に振動を加えることにより、その 洗浄度を高めるとともに、コンタミネーションの防止を図ることができる。 By adding vibration to the cleaning of the sample dispensing nozzle and the reagent dispensing nozzle, it is possible to increase the cleaning level and prevent contamination.

An oscillator 2 that generates ultrasonic waves is fixed to the reagent dispensing nozzle 1. The vibrator 2 is controlled by the CPU 7.
【０００８】 ＣＰＵ７より振動子２の電源８の電源ＯＮが指示される。次いでＣＰＵ７よりノ ズル１の洗浄が指示され、電磁弁５が開き、ノズル１内に水が供給され洗浄が開 始される。The CPU 7 instructs the power supply 8 of the vibrator 2 to be turned on. Next, the CPU 7 instructs the nozzle 1 to be washed, the solenoid valve 5 is opened, water is supplied into the nozzle 1, and the washing is started.
【０００９】 実施例２．（図は、実施例１と同様） ＣＰＵ７より洗浄槽１１での試薬分注ノズル洗浄が指示され、駆動部３が動作 し、試薬分注ノズル１を洗浄槽内へ位置を決定する。次いで、電磁弁９が開かれ 、洗浄槽１１に水が噴出される。洗浄槽１１には、水噴出口、及び排水口が設け られている。次いで、ＣＰＵ７より試薬分注ノズル水充填が指示され、試薬分注 機構４により、噴出水が試薬分注ノズル１内に充填される。次いで、ＣＰＵ７よ り振動子２の電源８の電源ＯＮが指示され、洗浄が開始される。Example 2. (The diagram is similar to that of the first embodiment.) The CPU 7 instructs the cleaning tank 11 to wash the reagent dispensing nozzle, and the drive unit 3 operates to determine the position of the reagent dispensing nozzle 1 in the washing tank.
