Description

Translated fromJapanese

本発明は、免疫学的凝集反応を行う複数の反応容器を有する反応カードの製造方法に関するものである。  The present invention relates to a method for producing a reaction card having a plurality of reaction vessels for performing an immunological agglutination reaction.

従来、血漿、血球または血清などの検体を免疫学的に分析する分析方法においては、検査内容に対応した試薬を専用の反応カード内の反応容器で検体と混和して反応させ、必要に応じてインキュベーションを行った後、その反応カードを遠心器で遠心することによって生じる反応像から凝集の有無を確認し、検体と試薬との凝集反応パターンをもとに検体が抗体または抗原に対して陰性であるか陽性であるかを判定する。  Conventionally, in an analysis method for immunologically analyzing a sample such as plasma, blood cells, or serum, a reagent corresponding to the test content is mixed with the sample in a reaction container in a dedicated reaction card and reacted. After incubation, the presence or absence of agglutination is confirmed from the reaction image generated by centrifuging the reaction card with a centrifuge. The sample is negative for antibody or antigen based on the agglutination pattern of the sample and reagent. Determine if it is positive or negative.

ところで、上述した反応カードの反応容器は、検体と試薬とを混合させて免疫学的凝集反応を行なわせる反応部と、反応部下部に連結され、免疫学的凝集反応を行なわせた反応液を、反応液の大きさに応じて移動度を変化させる担体を収容した分析部とを有している。分析部に収容する担体において、担体内に気泡が混入すると、気泡を凝集と誤判定する、または反応液の担体内へ移動度が変化する等、分析の結果に影響を及ぼすという問題があり、反応容器内に収容された担体内に気泡が混入していないことが望まれている。この問題に対し、気泡の混入を防ぐ方法として、混合物を収容した容器内を陰圧に設定して、脱気を行う製造方法が開示されている(例えば、特許文献1参照)。  By the way, the reaction container of the above-mentioned reaction card includes a reaction part that mixes a sample and a reagent to perform an immunological agglutination reaction, and a reaction solution that is connected to the lower part of the reaction part and that performs the immunological agglutination reaction. And an analysis unit containing a carrier whose mobility is changed according to the size of the reaction solution. In the carrier housed in the analysis unit, if bubbles are mixed in the carrier, there is a problem that the analysis results are affected, such as misjudging the bubbles as aggregation or the mobility of the reaction solution changes into the carrier, It is desired that bubbles are not mixed in the carrier accommodated in the reaction vessel. In order to prevent this problem, a manufacturing method is disclosed in which degassing is performed by setting the inside of the container containing the mixture to a negative pressure as a method for preventing the mixture of bubbles (for example, see Patent Document 1).

In addition, a cylindrical hole is formed in theblock 151, and anannular bearing 154 is provided on the upper plane of theblock 151 and in the vicinity of the outer periphery of the hole. Further, a cylindricalcontainer storage portion 152 that forms a space region inside and stores thecarrier holding container 18 in the space region is disposed above thebearing 154, and a meshingportion 153 is provided on the outer periphery of thecontainer storage portion 152. Is formed.

また、担体保持容器18は、大別して、上部に開口部を有し、担体Cを収容する担体収容部182と、担体収容部182の上部開口部を密閉する蓋183とで構成される。ここで、担体収容部182底部中央部には、送液管185が接続されており、送液管185外周と担体収容部182との間はベアリング184によって接続されている。同様に、蓋183においても、蓋183中央部に排気管186が接続され、排気管186外周は、ベアリング184を介して蓋183と接続されている。なお、送液管185は、担体保持容器18が容器収納部152に収納された場合に、容器収納部152およびブロック151に形成された孔に挿入される。上述した構成が、担体保持容器18に対応して複数設けられ、ギア191と歯合した歯合部153が、モータ19の駆動によるギア191の回転動力を受けて回転することで、隣接する歯合部153に動力を伝達する。歯合部153の回転に従って容器収納部152が回転することによって、担体保持容器18も回転し、担体保持容器18内に収容された担体Cが攪拌される。なお、容器収納部152の回転動力は、ベアリング154によってブロック151に伝達されない。  Thecarrier holding container 18 is roughly divided into acarrier accommodating portion 182 that has an opening in the upper portion and that accommodates the carrier C, and alid 183 that seals the upper opening of thecarrier accommodating portion 182. Here, aliquid feeding pipe 185 is connected to the bottom central part of thecarrier accommodating part 182, and the outer periphery of theliquid feeding pipe 185 and thecarrier accommodating part 182 are connected by abearing 184. Similarly, in thelid 183, anexhaust pipe 186 is connected to the center of thelid 183, and the outer periphery of theexhaust pipe 186 is connected to thelid 183 via abearing 184. In addition, when thecarrier holding container 18 is stored in thecontainer storage unit 152, theliquid feeding tube 185 is inserted into the holes formed in thecontainer storage unit 152 and theblock 151. A plurality of the above-described configurations are provided corresponding to thecarrier holding container 18, and the meshingportion 153 that meshes with thegear 191 rotates by receiving the rotational power of thegear 191 driven by themotor 19, so that adjacent teeth Power is transmitted to thejoint portion 153. As thecontainer storage unit 152 rotates in accordance with the rotation of themeshing unit 153, thecarrier holding container 18 also rotates, and the carrier C stored in thecarrier holding container 18 is stirred. In addition, the rotational power of thecontainer storage unit 152 is not transmitted to theblock 151 by thebearing 154.

上述した構成によって、モータ19の動力をギア191が担体保持容器18の歯合部153に伝達することによる担体Cの回転攪拌と、排気管186による減圧処理と、送液管185による分注処理とを同時に行なうことで、気泡を除去した担体Cを安定して反応容器に供給することができる。  With the configuration described above, thegear C 191 transmits the power of themotor 19 to the meshingportion 153 of thecarrier holding container 18, rotational stirring of the carrier C, decompression processing using theexhaust pipe 186, and dispensing processing using theliquid feeding pipe 185. The carrier C from which bubbles have been removed can be stably supplied to the reaction vessel.

つづいて、図5は、担体保持容器18が容器収納部152に収容された場合を示す模式図である。容器収納部152に収納された担体保持容器18には、送液管185に分注配管16が接続され、排気管186に脱気配管181が接続される。送液管185に連結された分注配管16は、容器収納部152およびブロック151に形成された孔を介してブロック151底部から図1,2に示す分注機構17まで延伸される。また、脱気配管181は、図1,2に示すように、一方がポンプ20に連結され、担体保持容器18内部の減圧を行なう。また、ベアリング184によって、担体保持容器18が回転した場合でも送液管185および排気管186は回転しないため、分注配管16および脱気配管181へ回転の動力が伝達されない。  FIG. 5 is a schematic diagram showing a case where thecarrier holding container 18 is accommodated in thecontainer accommodating portion 152. In thecarrier holding container 18 stored in thecontainer storage unit 152, the dispensingpipe 16 is connected to theliquid feeding pipe 185, and thedeaeration pipe 181 is connected to theexhaust pipe 186. Dispensingpipe 16 connected toliquid feeding pipe 185 extends from the bottom ofblock 151 to dispensingmechanism 17 shown in FIGS. 1 and 2 through a hole formed incontainer storage section 152 and block 151. As shown in FIGS. 1 and 2, one of thedeaeration pipes 181 is connected to thepump 20 to reduce the pressure inside thecarrier holding container 18. Further, even when thecarrier holding container 18 is rotated by thebearing 184, theliquid supply pipe 185 and theexhaust pipe 186 do not rotate, so that the rotational power is not transmitted to the dispensingpipe 16 and thedeaeration pipe 181.

ここで、図2に示すポンプ20とシリンジポンプ161との各圧力は、ポンプ20の圧力が、シリンジポンプ161の圧力と比して低いことが好ましい。特に、ポンプ20の吸引圧力が−40kPa〜−80kPaであって、シリンジポンプ161の吸引圧力が−100kPa〜−150kPaであることが好ましい。なお、上記範囲内であれば、ポンプ20とシリンジポンプ161との各吸引圧力は、如何なる組み合わせでもよい。また、分注時以外に送液管185による分注配管16または外部への担体Cの流出を防ぐため、送液管185に、圧力変化によって開閉する蓋を設けることが好ましく、分注配管16が接続された場合に開放可能な開閉機構を送液管185の外部側先端に設けてもよい。ここで、開閉機構は、分注配管16が接続されて送液管185が開放された場合であっても、分注配管16の内部圧力によって担体Cの流出を防止し、シリンジポンプ161の駆動によってのみ担体Cが放出されることが好ましい。  Here, each pressure of thepump 20 and thesyringe pump 161 shown in FIG. 2 is preferably lower than the pressure of thesyringe pump 161. In particular, the suction pressure of thepump 20 is preferably −40 kPa to −80 kPa, and the suction pressure of thesyringe pump 161 is preferably −100 kPa to −150 kPa. In addition, if it is in the said range, each suction pressure of thepump 20 and thesyringe pump 161 may be any combination. Further, in order to prevent the dispensingpipe 16 through theliquid feeding pipe 185 or outflow of the carrier C to the outside other than at the time of dispensing, theliquid feeding pipe 185 is preferably provided with a lid that opens and closes due to pressure change. An open / close mechanism that can be opened when is connected may be provided at the outer end of theliquid feeding pipe 185. Here, the opening / closing mechanism prevents the carrier C from flowing out by the internal pressure of the dispensingpipe 16 even when the dispensingpipe 16 is connected and theliquid feeding pipe 185 is opened, and thesyringe pump 161 is driven. It is preferred that the carrier C is released only by

また、攪拌の効率を向上させるために加温する場合は、担体C中の内容物の活性が失活しない温度以下であれば加温してもよい。各容器収納部152に加温機構を設けることで温度調節を行なうことが可能となる。  Moreover, when heating in order to improve the efficiency of stirring, as long as it is below the temperature which the activity of the content in the support | carrier C does not deactivate, you may heat. Temperature adjustment can be performed by providing a heating mechanism in eachcontainer storage unit 152.

上述した実施の形態1にかかる反応カード製造装置は、攪拌処理、減圧処理および分注処理を同時に行なうことで、担体中の気泡を除去して反応容器内に分注することができるため、分析結果の安定した精度の高い分析を行うことが可能となる。  The reaction card manufacturing apparatus according to the first embodiment described above can remove bubbles in the carrier and dispense into the reaction container by simultaneously performing the stirring process, the decompression process, and the dispensing process. It is possible to perform a stable and accurate analysis of the results.

図6,7は、実施の形態2にかかる反応カード製造装置の保持部を示す模式図である。図6,7に示す保持部15において、担体保持容器18は、担体収容部182側面に歯合部187を有し、ベアリング154の上部の形状に対応した凹部188が底部に形成されている。担体保持容器18の凹部188がベアリング154と嵌合することによって、担体保持容器18がブロック151に支持され、歯合部187がギア191若しくは隣接する担体保持容器18の歯合部と歯合して、ギア191を介してモータ19の動力が伝達され、担体保持容器18を回転させることができる。
(Embodiment 2)
6 and 7 are schematic diagrams illustrating a holding unit of the reaction card manufacturing apparatus according to the second embodiment. In the holdingpart 15 shown in FIGS. 6 and 7, thecarrier holding container 18 has a meshingpart 187 on the side surface of thecarrier accommodating part 182, and aconcave part 188 corresponding to the shape of the upper part of thebearing 154 is formed in the bottom part. By fitting therecess 188 of thecarrier holding container 18 with thebearing 154, thecarrier holding container 18 is supported by theblock 151, and the meshingportion 187 meshes with thegear 191 or the meshing portion of the adjacentcarrier holding container 18. Thus, the power of themotor 19 is transmitted through thegear 191 and thecarrier holding container 18 can be rotated.

また、図7に示すように、担体保持容器18の凹部188がベアリング154と嵌合すると、送液管185に分注配管16を接続し、排気管186に脱気配管181を接続する。実施の形態1と同様に、担体保持容器18の回転動力は、ベアリング154,184によってブロック151、送液管185および排気管186には伝達しない。上述した構成によって、モータ19の動力をギア191が担体保持容器18の歯合部187に伝達することによる担体Cの回転攪拌と、排気管186による減圧処理と、送液管185による分注処理とを同時に行なうことで、気泡を除去した担体Cを安定して反応容器に供給することができる。  Further, as shown in FIG. 7, when theconcave portion 188 of thecarrier holding container 18 is fitted with thebearing 154, the dispensingpipe 16 is connected to theliquid feeding pipe 185 and thedegassing pipe 181 is connected to theexhaust pipe 186. As in the first embodiment, the rotational power of thecarrier holding container 18 is not transmitted to theblock 151, theliquid feeding pipe 185 and theexhaust pipe 186 by thebearings 154 and 184. With the configuration described above, thegear C 191 transmits the power of themotor 19 to the meshingportion 187 of thecarrier holding container 18, rotational stirring of the carrier C, decompression processing using theexhaust pipe 186, and dispensing processing using theliquid feeding pipe 185. The carrier C from which bubbles have been removed can be stably supplied to the reaction vessel.

実施の形態2にかかる反応カード製造装置は、担体保持容器の外周に歯合部を設けたため、簡易な構成で攪拌処理を行うことが可能となる。  Since the reaction card manufacturing apparatus according to the second embodiment is provided with the engagement portion on the outer periphery of the carrier holding container, it is possible to perform the stirring process with a simple configuration.

なお、ブロックにおける容器収納部またはベアリングの配置は、行と列との二次元の配置でもよい。また、分注配管は、金属等の剛性の高い部材を用いてもよく、ゴム等の剛性の低い部材を用いてもよい。  The arrangement of the container storage portion or the bearing in the block may be a two-dimensional arrangement of rows and columns. In addition, the dispensing pipe may be made of a highly rigid member such as metal, or may be made of a less rigid member such as rubber.

上述した実施の形態1,2にかかる反応カード製造装置は、攪拌処理および減圧処理を行いながら分注処理が可能なため、反応容器に分注した担体内に気泡が混入することを防止し、安定して精度の高い分析を行うことができる反応カードを製造することが可能となる。また、均一に攪拌された担体を反応容器に分注することができるため、内容物に試薬等が混合されている場合でも、各反応容器に均一に分注することが可能となる。  The reaction card manufacturing apparatus according to the first and second embodiments described above is capable of dispensing while performing a stirring process and a decompression process, thus preventing bubbles from being mixed into the carrier dispensed in the reaction vessel, It becomes possible to manufacture a reaction card capable of performing a stable and highly accurate analysis. In addition, since the uniformly stirred carrier can be dispensed into the reaction container, even when a reagent or the like is mixed in the contents, it can be evenly dispensed into each reaction container.
