本発明は、試料及び試薬等の検液を反応容器内に収容し
て、測光により検液の分析を行なうための、反応容器に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a reaction container for storing a test solution such as a sample and a reagent in the reaction container and analyzing the test solution by photometry.
従来、このような分析を行なう場合、例えば透光性を有
する反応容器を移送機構によって所定の反応ラインに沿
ってステップ移送させ、各ステップで試料及び試薬の分
注、攪拌、測光１反応容器の洗浄又は廃棄等の処理が行
なわれるようになっている。Conventionally, when performing such an analysis, for example, a translucent reaction vessel is moved step by step along a predetermined reaction line by a transfer mechanism, and at each step, samples and reagents are dispensed, stirred, and one photometric reaction vessel is moved. Processing such as cleaning or disposal is now performed.
ところで、試料を分注する場合には試料分注プローブを
用いて分注器によって、試料をサンプラから吸引して反
応容器へ分注し、又試薬を分注する場合には試薬分注プ
ローブを用いて、同様に反応容器に分注して反応させる
ことが一般的に行なわれている。そして、各プローブは
試料や試薬が変わるたび毎に、多量の洗浄液を使用して
洗浄することを必要としていた。又、検液の攪拌方法に
ついても、反応容器内の検液中に撹拌棒を挿入して攪拌
を行なうようにしていた。By the way, when dispensing a sample, a sample dispensing probe is used to aspirate the sample from the sampler and dispensing it into a reaction container, and when dispensing a reagent, a reagent dispensing probe is used. It is common practice to use the same method and dispense it into a reaction vessel for reaction. Further, each probe needs to be washed using a large amount of washing liquid every time the sample or reagent is changed. Also, regarding the method of stirring the test liquid, stirring was performed by inserting a stirring rod into the test liquid in the reaction container.
又、別の分析方法として特公昭６４−１２３４５号公報
に記載された自動分析方法があり、この方法では、攪拌
手段として反応容器の下部を可撓性にすると共にこの部
分を押圧する押し上げ用押圧機構を用いて、検液の攪拌
を行なうようにしている。又、分析に用いる検液量を少
なくするために、測光時に反応容器の下部を押し上げ用
押圧機構で押しつぶして、検液を反応容器内の測光位置
まで押し上げるようにしている。Another analysis method is an automatic analysis method described in Japanese Patent Publication No. 64-12345. In this method, the lower part of the reaction vessel is made flexible as a stirring means, and a pushing force is used to press this part. A mechanism is used to stir the test solution. Furthermore, in order to reduce the amount of test liquid used for analysis, the lower part of the reaction container is pressed down by a push-up mechanism during photometry to push the test liquid up to the photometry position within the reaction container.
しかし、これらの場合、試料用と試薬用のプローブが夫
々必要であり、移送機構においてこれらの移送手段が夫
々必要となるから、機構が複雑になってしまう。However, in these cases, probes for the sample and probes for the reagent are required, and the transport mechanism requires separate means for transporting these, resulting in a complicated mechanism.
又、分注の際、反応容器上部の開口部からプローブを介
して分注を行なうため、プローブ移送時の位置精度との
関係で開口部をある程度大きくする必要があり、反応容
器を小型化することができない。このため、反応ライン
のスペースが大きくなるという問題がある。しかも、反
応容器を小型化できないため、検液量の微量化かできず
、患者からの採血量を減少できない上に試薬も減量でき
ないために検査コストを下げることができない。In addition, since dispensing is performed through the probe from the opening at the top of the reaction vessel, the opening needs to be made somewhat large due to the positional accuracy during probe transfer, which makes it necessary to downsize the reaction vessel. I can't. Therefore, there is a problem that the space for the reaction line becomes large. Moreover, since the reaction container cannot be miniaturized, the amount of test liquid cannot be reduced, and the amount of blood collected from the patient cannot be reduced, and the amount of reagents cannot be reduced, so testing costs cannot be reduced.
尚、上述した後者の従来技術では検液量を比較的少なく
することができるが、測光時において押し上げ用押圧機
構や駆動モータが必要であるから機構が複雑化して検査
コストが上昇するという問題が生じる。Although the latter conventional technique described above allows the amount of test liquid to be relatively small, it requires a push-up mechanism and a drive motor during photometry, which complicates the mechanism and increases inspection costs. arise.
更に各プローブを洗浄するために多量の洗浄液や水が必
要になり、又廃液量も多くなるという問題もある。Furthermore, a large amount of cleaning liquid and water are required to clean each probe, and there is also the problem that the amount of waste liquid increases.
又、上述の従来例では攪拌するための機構か別に必要で
あり、前者の場合には検液が撹拌棒に付着するため、撹
拌棒の洗浄か必要であり、洗浄後になお付着している検
液によって別の分析の際の分析精度に悪影響を及はすと
いう問題かある。後者の場合には攪拌用押圧機構及び駆
動モータか必要であり、機構の複雑化及びコストの上昇
を招くことになる。In addition, in the conventional example described above, a separate mechanism for stirring is required, and in the former case, the test liquid adheres to the stirring rod, so it is necessary to clean the stirring rod, and the test liquid still attached after cleaning must be cleaned. There is a problem that depending on the liquid, the accuracy of analysis during other analyzes may be adversely affected. In the latter case, a pressing mechanism for agitation and a drive motor are required, resulting in a complicated mechanism and an increase in cost.
尚、試料用のプローブと反応容器が夫々ディスポーザブ
ル（使い捨て可能）のものもあるが、これらは別個に構
成されているから分析コストを上昇させることになる。Incidentally, there are some cases in which the sample probe and the reaction container are each disposable, but since these are constructed separately, this increases the analysis cost.
本発明はこのような問題点に鑑みて、プローブの移送手
段を省略できて、攪拌の手段を簡単化できると共に容積
を小型化できるようにした反応容器を提供することを目
的とするものである。In view of these problems, it is an object of the present invention to provide a reaction container that can omit the means for transporting the probe, simplify the means for stirring, and reduce the volume. .
本発明による反応容器は、反応容器部とプローブ部とか
一体に形成されていると共に、この反応容器が偏平形状

構成されている。In the reaction container according to the present invention, the reaction container portion and the probe portion are integrally formed, and the reaction container has a flat shape, and two opposing flat surfaces are configured as photometric cell surfaces.

ル面に光が照射されて測定が行なわれることになる。To dispense a sample or reagent, insert the tip of the probe into the sample or reagent and aspirate it with the dispenser, the sample or reagent will be injected from the probe into the reaction container, and then dispensed into each sample or reagent. After dispensing, the outside of the probe section can be washed with diluent or water, so there is almost no need for cleaning solution, and when stirring, the tip of the probe section can be moved into the air and suctioned with a dispenser, allowing air to flow easily. is sucked from the probe section and moves in the form of bubbles through the test liquid in the reaction container section, allowing for sufficient stirring.Also, during photometry, light is irradiated onto the flat photometry cell surface to perform measurements. become.

There is no need to increase the diameter. Moreover, the reaction container part 2 has a pair of flat photometric cell surfaces 2b, 2 facing each other.
Since it is formed into a flat shape according to b, the reaction container part 2

構及び駆動モータ等を必要としない。Furthermore, since the sample liquid and the like can be stirred by sucking air from the probe section 3 with a dispenser, there is no need for a stirring rod, a stirring pressing mechanism, a drive motor, or the like.
更に、プローブ部３と反応容器部２か一体であるから、
反応容器１をディスポーザブルとした場合、コストを低

る。As described above, in the reaction container according to the present invention, the reaction container part and the probe part are integrally formed, and the reaction container part is flattened so that the flat surface is formed on the photometric cell surface. The operation and structure of the transfer mechanism can be simplified, and stirring rods and pressing mechanisms are no longer required during stirring. Moreover, during each step, almost no cleaning liquid is required for cleaning, there is little waste liquid, and if the reaction vessel is disposable, the cost can be reduced. Furthermore, since the reaction container can be made smaller and have a smaller capacity than conventional ones, the amount of samples, reagents, etc. required for testing can be reduced to a very small amount. Further, since the sample, reagent, diluent, air, etc. are sucked in only one direction of the probe part, there is an advantage that co-washing is possible and there is no carryover.
