Description

本発明は、血液、血清、尿等の検体を分析する生化学自動分析装置の検体容器搬送機構に関する。 The present invention relates to a specimen container transport mechanism of a biochemical automatic analyzer that analyzes specimens such as blood, serum, and urine.

例えば血液や尿のような生体試料（検体）の分析を行なう生化学自動分析装置は、搬送されてきた検体容器中の検体を反応ディスクにより支持された反応セルにサンプルピペットノズルを用いて分取し、これに試薬容器から試薬ピペットノズルによって吸引した試薬を添加して、反応セル内で検体と試薬とを反応させ、この反応によって生じた発色の状態を、例えば多波長光度計等の検出器で検出することにより、検体を複数項目について分析する。   For example, an automatic biochemical analyzer that analyzes a biological sample (specimen) such as blood or urine uses a sample pipette nozzle to sort the specimen in the transported specimen container into a reaction cell supported by a reaction disk. Then, the reagent sucked from the reagent container by the reagent pipette nozzle is added thereto, the sample and the reagent are reacted in the reaction cell, and the color developed by this reaction is detected by a detector such as a multi-wavelength photometer. By detecting the sample, the sample is analyzed for a plurality of items.

このような生化学自動分析装置においては、検体を収容した検体容器を外部あるいは回収ラインから分析部にスムーズに搬送するために、外部あるいは回収ラインにつながる搬送ベルト上から分析部につながる別の搬送ベルト上に検体容器を載せ換える作業が必要となる。この作業を自動的に行なっているのが、検体容器載せ換え機構である。   In such a biochemical automatic analyzer, in order to smoothly transport the sample container containing the sample from the outside or the collection line to the analysis unit, another conveyance connected to the analysis unit from the outside or from the conveyance belt connected to the collection line. It is necessary to replace the sample container on the belt. This operation is automatically performed by the specimen container replacement mechanism.

従来の検体容器載せ換え機構について説明する。図１は、従来の検体容器載せ換え機構の動作を説明した図である。図中１は、外部あるいは回収ラインから検体容器載せ換え機構３に検体容器２を運び込む第１の搬送ベルトである。図１（ａ）は、検体載せ換え機構３が検体容器２を受け取るために待機している初期状態を表わしている。   A conventional specimen container replacement mechanism will be described. FIG. 1 is a diagram for explaining the operation of a conventional specimen container replacement mechanism. In the figure, reference numeral 1 denotes a first transport belt that carries the sample container 2 from the outside or the collection line to the sample container replacement mechanism 3. FIG. 1A shows an initial state in which the sample changing mechanism 3 is on standby for receiving the sample container 2.

まず、第１の搬送ベルト１によって運び込まれた検体容器２は、検体容器載せ換え機構３の搬送ベルト１と対向する面側に設けられた検体容器受け取り部４に受け渡される（図１の（ｂ））。   First, the sample container 2 carried in by the first transport belt 1 is delivered to the sample container receiving portion 4 provided on the surface facing the transport belt 1 of the sample container replacement mechanism 3 ((( b)).

検体容器載せ換え機構３は、検体容器２受け取り後、右方向に移動し、図示しない分析部につながる第２の搬送ベルト５に対向する位置で停止する（図１の（ｃ））。もし、検体容器が回収ラインからもたらされた空容器である場合は、ここで分注ピペットによる試料液の分注が行なわれる。   After receiving the sample container 2, the sample container changing mechanism 3 moves to the right and stops at a position facing the second transport belt 5 connected to an analysis unit (not shown) ((c) in FIG. 1). If the sample container is an empty container brought from the collection line, the sample liquid is dispensed by a dispensing pipette here.

その後、この位置で検体容器受け取り部４は検体容器２を放し、検体容器２は第２の搬送ベルト５によって図示しない分析部へと送られる（図１の（ｄ））。   Thereafter, at this position, the sample container receiving unit 4 releases the sample container 2, and the sample container 2 is sent to an analysis unit (not shown) by the second transport belt 5 ((d) in FIG. 1).

従来の生化学自動分析装置では、検体容器載せ換えの対象となる搬送ベルトは２本しか存在していなかったため、検体容器載せ換え機構３はきわめて単純な構成であった。ところが、所望の検体を分析部で分析後、分析結果が異常値を示すと、検出器が分析可能範囲を超えてしまい、正しい結果が得られないため、同検体をもう一度希釈し直して再検する必要が発生する。   In the conventional biochemical automatic analyzer, there are only two conveyor belts to be replaced with the sample container, and thus the sample container replacement mechanism 3 has a very simple configuration. However, after analyzing the desired sample in the analysis section, if the analysis result shows an abnormal value, the detector will exceed the analyzable range, and the correct result cannot be obtained. Need arises.

再検のための検体容器は、分析部から検体容器載せ換え機構３の位置まで、第２の搬送ベルトとは反対の方向に搬送する必要があり、その目的のため、第３の搬送ベルトが設けられるようになった。   The sample container for the retest needs to be transported from the analysis unit to the position of the sample container replacement mechanism 3 in the direction opposite to the second transport belt. For this purpose, a third transport belt is provided. It came to be able to.

その結果、検体容器載せ換え機構３は、第１の搬送ベルトから送られてくる新たな検体容器を第２の搬送ベルトに載せ換える動作を行なうと同時に、再検用の検体容器が第３の搬送ベルトで回送されてきた場合には、再検用の検体容器も第３の搬送ベルトから第２の搬送ベルトに載せ換える動作を行なわなければならなくなった。   As a result, the sample container replacement mechanism 3 performs the operation of replacing the new sample container sent from the first transport belt with the second transport belt, and at the same time the sample container for retesting is transported to the third transport belt. In the case of being transported by a belt, it is necessary to perform an operation of transferring the sample container for retesting from the third transport belt to the second transport belt.

その検体容器載せ換え機構の従来の動作について説明する。図２は、新たに複雑化した検体容器載せ換え機構の動作を説明した図である。図中１は、外部あるいは回収ラインから検体容器載せ換え機構３に検体容器２を運び込む第１の搬送ベルトである。図２（ａ）は、検体載せ換え機構３が検体容器２を受け取るために待機している初期状態を表わしている。   The conventional operation of the specimen container changing mechanism will be described. FIG. 2 is a diagram for explaining the operation of the newly complicated specimen container replacement mechanism. In the figure, reference numeral 1 denotes a first transport belt that carries the sample container 2 from the outside or the collection line to the sample container replacement mechanism 3. FIG. 2A shows an initial state in which the sample changing mechanism 3 is on standby for receiving the sample container 2.

まず、第１の搬送ベルト１によって運び込まれた検体容器２は、検体容器載せ換え機構３の搬送ベルト１と対向する面側に設けられた検体容器受け取り部４に受け渡される（図２の（ｂ））。   First, the sample container 2 carried in by the first transport belt 1 is delivered to the sample container receiving portion 4 provided on the surface facing the transport belt 1 of the sample container replacement mechanism 3 ((( b)).

検体容器載せ換え機構３は、検体容器２受け取り後、右方向に移動し、図示しない分析部につながる第２の搬送ベルト５に対向する位置で停止する（図２の（ｃ））。もし、検体容器が回収ラインからもたらされた空容器である場合は、ここで分注ピペットによる試料液の分注が行なわれる。   After receiving the sample container 2, the sample container changing mechanism 3 moves to the right and stops at a position facing the second transport belt 5 connected to an analysis unit (not shown) ((c) in FIG. 2). If the sample container is an empty container brought from the collection line, the sample liquid is dispensed by a dispensing pipette here.

その後、この位置で検体容器受け取り部４は検体容器２を放し、検体容器２は第２の搬送ベルト５によって図示しない分析部へと送られる（図２の（ｄ））。   Thereafter, at this position, the sample container receiving unit 4 releases the sample container 2, and the sample container 2 is sent to an analysis unit (not shown) by the second transport belt 5 ((d) in FIG. 2).

第３の搬送ベルト６によって図示しない分析部から再検用の検体容器７が運び込まれたときには、検体容器載せ換え機構３はさらに右方向に移動し、第３の搬送ベルト６から再検用の検体容器７を検体容器受け取り部４において受け取る（図２の（ｅ））。   When the sample container 7 for retesting is carried in from the analyzing section (not shown) by the third transport belt 6, the sample container replacement mechanism 3 further moves to the right, and the sample container for retesting is transported from the third transport belt 6. 7 is received by the sample container receiving unit 4 ((e) of FIG. 2).

検体容器載せ換え機構３は、検体容器７受け取り後、左方向に移動し、図示しない分析部につながる第２の搬送ベルト５に対向する位置で停止する（図２の（ｆ））。   After receiving the sample container 7, the sample container changing mechanism 3 moves to the left and stops at a position facing the second transport belt 5 connected to an analysis unit (not shown) ((f) in FIG. 2).

この位置で検体容器受け取り部４は検体容器７を放し、検体容器７は第２の搬送ベルト５によって図示しない分析部へと送られる（図２の（ｇ））。   At this position, the sample container receiving unit 4 releases the sample container 7, and the sample container 7 is sent to an analysis unit (not shown) by the second transport belt 5 ((g) in FIG. 2).

このような２つの搬送ベルトによって送られてくる検体容器を１台の検体容器載せ換え機構３で分析部に通じる搬送ベルトに載せ換える方法は、検体容器載せ換え機構３が、その都度、搬送ベルトの対向位置まで移動しなければならず、動作に移動のための待ち時間がかかるという問題があった。この問題を解決するために、検体容器載せ換え機構を２台に増やすことも考えられるが、検体容器載せ換え機構を２台に増やすと、コストが２倍に増大してしまうという問題があった。   The method of transferring the sample container sent by the two transport belts to the transport belt that communicates with the analysis unit by using one sample container replacement mechanism 3 is that the sample container replacement mechanism 3 performs the transport belt each time. Therefore, there is a problem that it takes a waiting time for the movement. In order to solve this problem, it is conceivable to increase the number of specimen container replacement mechanisms to two. However, if the number of specimen container replacement mechanisms is increased to two, there is a problem that the cost increases twice. .

本発明の目的は、上述した点に鑑み、２つの搬送ベルトによって送られてくる検体容器を１台の検体容器載せ換え機構のみを用い、安価かつ高速に載せ換えを可能にする生化学自動分析装置の検体容器搬送機構を提供することにある。   In view of the above-described points, an object of the present invention is to perform automatic biochemical analysis that enables a sample container sent by two transport belts to be replaced at low cost and at high speed using only one sample container replacement mechanism. An object of the present invention is to provide a specimen container transport mechanism of an apparatus.

According to the automatic analyzer of the present invention,
The first, second, and third transport belts arranged in this order, wherein the first transport belt carries an empty sample container, and the second transport belt is the first transport belt. the conveyor belt Hakobidashi to the analysis portion of the drive has been sample container in the opposite direction, sample containers returned for re-inspection from the third conveyor belt is driven in the first conveyance belt in the same way analysis unit And a sample container transfer means for transferring the sample containers carried by the first and third transport belts from the first and third transport belts to the second transport belt When, the specimen in the specimen container is replaced placed on the second conveyor belt or the specimen vessel placed recombinant means an automatic analyzer that includes a dispensing mechanism for dispensing a diluent,
The sample container changing means includes two container receiving units, and when one container receiving unit performs an operation of transferring the sample container received from the first conveying belt to the second conveying belt, the sample container changing unit is already at the same time. One container receiving section operates to receive another sample container on the third transport belt, and the container receiving section replaces the sample container received from the third transport belt with the second transport belt. when performing simultaneously with the other sample container receiving section is operated to go to pick up another sample container to the first conveyor belt, placed from the first conveyance belt to the second conveyor belt for recombinant was sample container is dispensed test body is divided from the dispensing mechanism, for the third sample container which is replaced placed on the second conveyor belt from the conveyor belt of the rare from the dispensing mechanism Since it operates so that the liquid is dispensed,
It has become possible to provide an automatic biochemical analyzer that allows a sample container sent by two conveyor belts to be replaced at low cost and at high speed by using only one sample container mechanism.

以下、図面に基づいて、本発明の実施例について説明する。図３は、本発明にかかる検体容器載せ換え機構の動作を説明した図である。図中１は、外部あるいは回収ラインから検体容器載せ換え機構３に検体容器２を運び込む第１の搬送ベルトである。図３（ａ）は、検体載せ換え機構３が検体容器２を受け取るために待機している初期状態を表わしている。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is a diagram for explaining the operation of the specimen container changing mechanism according to the present invention. In the figure, reference numeral 1 denotes a first transport belt that carries the sample container 2 from the outside or the collection line to the sample container replacement mechanism 3. FIG. 3A shows an initial state in which the sample changing mechanism 3 is on standby for receiving the sample container 2.

まず、第１の搬送ベルト１によって運び込まれた検体容器２は、検体容器載せ換え機構３の搬送ベルト１と対向する面側に設けられた検体容器受け取り部４に受け渡される（図３の（ｂ））。   First, the sample container 2 carried in by the first transport belt 1 is delivered to the sample container receiving section 4 provided on the surface facing the transport belt 1 of the sample container replacement mechanism 3 ((( b)).

このとき、検体容器載せ換え機構３には、２つの容器受け取り部４、４’が設けられていて、その間隔は、検体容器載せ換え機構３の近傍での隣り合う３本の搬送ベルト間の間隔と等間隔になるように設定されている。 At this time, the sample container changing mechanism 3 is provided with two container receiving portions 4, 4 ′ , and the interval between the adjacent three conveyor belts in the vicinity of the sample container changing mechanism 3. It is set to be equal to the interval.

検体容器載せ換え機構３の移動により、２つの容器受け取り部４、４’は一体的に移動する。その結果、容器受け取り部４は、第１の搬送ベルト１と第２の搬送ベルト５との間のみを移動し、それに連動して、容器受け取り部４’は、第２の搬送ベルト５と第３の搬送ベルト６との間のみを移動する。 Due to the movement of the sample container changing mechanism 3, the two container receiving portions 4, 4 ′ move integrally. As a result, the container receiver 4 moves only between the first conveyor belt 1 and the second conveyor belt 5, and in conjunction with this, the container receiver 4 ′ is connected to the second conveyor belt 5 and the second conveyor belt 5. It moves only between the three conveyor belts 6.

なお、外部あるいは回収ラインから検体容器載せ換え機構に検体容器２を運び込む第１の搬送ベルト１と、分析部につながる第２の搬送ベルト５と、再検用の検体容器７を回送する第３の搬送ベルト６とは、検体容器載せ換え機構３の近傍で互いに平行かつ等間隔になるように配置されている。   A third transport belt 1 that transports the sample container 2 from the outside or the collection line to the sample container repositioning mechanism, a second transport belt 5 that is connected to the analysis unit, and a third container 7 for retesting. The conveyor belt 6 is arranged in the vicinity of the sample container remounting mechanism 3 so as to be parallel to each other and at equal intervals.

検体容器載せ換え機構３は、検体容器２受け取り後、右方向に移動し、図示しない分析部につながる第２の搬送ベルト５に対向する位置で停止する（図３の（ｃ））。もし、検体容器が回収ラインからもたらされた空容器である場合は、ここで分注ピペットによる試料液の分注が行なわれる。   After receiving the sample container 2, the sample container changing mechanism 3 moves to the right and stops at a position facing the second transport belt 5 connected to an analysis unit (not shown) ((c) in FIG. 3). If the sample container is an empty container brought from the collection line, the sample liquid is dispensed by a dispensing pipette here.

その後、この位置で検体容器受け取り部４は検体容器２を放し、検体容器２は第２の搬送ベルト５によって図示しない分析部へと送られる（図３の（ｄ））。   Thereafter, at this position, the sample container receiving unit 4 releases the sample container 2, and the sample container 2 is sent to an analysis unit (not shown) by the second transport belt 5 ((d) in FIG. 3).

このとき、もう１つの検体容器受け取り部４’は、第３の搬送ベルト６と対向する位置に来ている。よって、図示しない分析部から再検用の検体容器７が運び込まれたときには、検体容器載せ換え機構３は、まったく移動することなく、第３の搬送ベルト６から再検用の検体容器７を検体容器受け取り部４’において受け取ることができる（図３の（ｄ））。 At this time, the other sample container receiving portion 4 ′ is at a position facing the third transport belt 6. Therefore, when the reexamination sample container 7 is carried in from an analysis unit (not shown), the sample container replacement mechanism 3 receives the reexamination sample container 7 from the third transport belt 6 without moving at all. It can be received at part 4 ′ (FIG. 3 (d)).

検体容器載せ換え機構３は、検体容器７受け取り後、左方向に移動し、図示しない分析部につながる第２の搬送ベルト５に対向する位置で停止する（図３の（ｅ））。   After receiving the sample container 7, the sample container changing mechanism 3 moves to the left and stops at a position facing the second transport belt 5 connected to an analysis unit (not shown) ((e) in FIG. 3).

この位置で検体容器受け取り部４は検体容器７を放し、検体容器７は第２の搬送ベルト５によって図示しない分析部へと送られる（図３の（ｆ））。   At this position, the sample container receiving unit 4 releases the sample container 7, and the sample container 7 is sent to an analysis unit (not shown) by the second transport belt 5 ((f) in FIG. 3).

このとき、最初の検体容器受け取り部４は、第１の搬送ベルト１と対向する位置に戻って来ている。よって、外部または回収ラインから新しい検体容器２’が運び込まれたときには、検体容器載せ換え機構３は、まったく移動することなく、第１の搬送ベルト１から新しい検体容器２’を検体容器受け取り部４において受け取ることができる（図３の（ｆ））。 At this time, the first specimen container receiving unit 4 has returned to the position facing the first transport belt 1. Therefore, when a new sample container 2 ′ is carried in from the outside or the collection line, the sample container replacement mechanism 3 moves the sample container 2 ′ from the first transport belt 1 without moving at all. (F) in FIG.

このように、本発明にかかる検体容器搬送機構は、第１の搬送ベルト１で受け取った検体容器２を第２の搬送ベルトに載せ換える動作を行なうと、自動的に第３の搬送ベルト６に再検用の検体容器７を取りに行く動作をも行なうことになるので、再検用の検体容器７を取りに行くための移動待ち時間を省略することができる。   As described above, the sample container transport mechanism according to the present invention automatically moves to the third transport belt 6 when the sample container 2 received by the first transport belt 1 is replaced with the second transport belt. Since the operation of taking the sample container 7 for retesting is also performed, the waiting time for moving to get the sample container 7 for retesting can be omitted.

また、同様に、第３の搬送ベルト６で受け取った再検用の検体容器７を第２の搬送ベルトに載せ換える動作を行なうと、自動的に第１の搬送ベルト１に次の検体容器２’を取りに行く動作をも行なうことになるので、検体容器２’を取りに行くための移動待ち時間を省略することができる。 Similarly, when an operation for replacing the sample container 7 for retesting received by the third transport belt 6 with the second transport belt is performed, the next sample container 2 ′ is automatically placed on the first transport belt 1. Therefore, the waiting time for moving to get the sample container 2 ′ can be omitted.

こうして、２つの搬送ベルトによって送られてくる検体容器を１台の検体容器載せ換え機構のみで移動待ち時間を設けることなく１本の搬送ベルト上に載せ換えることが可能になり、安価かつ高速な生化学自動分析装置の検体容器搬送機構が提供することが可能になった。   In this way, it is possible to transfer the sample containers sent by the two conveyance belts onto one conveyance belt without providing a waiting time for movement with only one sample container replacement mechanism, which is inexpensive and fast. It has become possible to provide a specimen container transport mechanism of a biochemical automatic analyzer.

以下、本発明の一実施例について説明する。図４は、本発明の一実施例を示したものである。本搬送システムは、検体容器を分析部に搬出するベルトＡ、分析後の検体容器を回収搬入するベルトＢ、再検試料の入った再希釈容器のみを搬入するベルトＣ、Ａ-イまたはＢ-イの位置において再検用の検体容器をベルトＣに載せ換える第１の検体容器載せ換え機構Ｆ、Ｂ-ロまたはＣ-ロの位置において分析のため検体容器をベルトＡに載せ換える第２の検体容器載せ換え機構Ｄ、Ａ-ロの位置へ試料液や希釈液を搬送し吐出するための分注ピペットＥより成る。   Hereinafter, an embodiment of the present invention will be described. FIG. 4 shows an embodiment of the present invention. In this transport system, belt A for transporting the sample container to the analysis unit, belt B for collecting and transporting the sample container after analysis, and belt C, A-i or B-i for carrying only the re-dilution container containing the retest sample. The second sample container for transferring the sample container to the belt A for analysis at the position of the first sample container changing mechanism F, B-B or C-B for transferring the sample container for retesting to the belt C at the position It consists of a dispensing pipette E for transporting and discharging the sample liquid and diluent to the position of the transfer mechanism D, A-ro.

第２の検体容器載せ換え機構Ｄは、図４および図５に示すように、図面に対して左右方向に動き、ベルトＡ、Ｂ、Ｃと対向する側には、検体容器を保持するため、偏芯カムの回転で開閉するツメが２組取り付けられている。   As shown in FIGS. 4 and 5, the second specimen container changing mechanism D moves in the left-right direction with respect to the drawings, and holds the specimen container on the side facing the belts A, B, and C. Two sets of claws that are opened and closed by the rotation of the eccentric cam are attached.

この搬送システムの動作は次の通りである。まず、ベルトＢにより回送されて来た使用済み検体容器は、洗浄機構で洗浄されて空容器となり、次の試料液を分注可能な状態になり、Ｂ-ロの位置から第２の検体容器載せ換え機構Ｄのツメ（Ｉ）によりＡ-ロの位置に運ばれ、Ａ-ロの位置で分注ピペットＥにより試料液（と希釈液）が分注される。   The operation of this transport system is as follows. First, the used sample container that has been transported by the belt B is cleaned by the cleaning mechanism to become an empty container, and is ready for dispensing the next sample solution. From the position B-B to the second sample container It is carried to the A-ro position by the claw (I) of the transfer mechanism D, and the sample liquid (and the diluting liquid) is dispensed by the dispensing pipette E at the A-ro position.

分注を完了した検体容器は、ベルトＡにより図示しない分析部に搬送され、分析が行なわれる。   The sample container that has been dispensed is transported to an analysis unit (not shown) by the belt A and analyzed.

分析が完了した検体容器は、通常、再びベルトＢにより回送されて来て再利用されるが、分析結果が異常値であった場合は、洗浄機構へは進まず、Ｂ-イの位置において第１の検体容器載せ換え機構ＦによってベルトＣに載せ換えられ、ベルトＣによってＣ-ロの位置まで運ばれる。   The sample container that has been analyzed is usually sent again by the belt B and reused. However, if the analysis result is an abnormal value, the sample does not proceed to the cleaning mechanism, and the first container is located at the position B-A. 1 is transferred to the belt C by the specimen container changing mechanism F, and is carried to the position C-B by the belt C.

Ｃ-ロの位置に運ばれて来た検体容器は、第２の検体容器載せ換え機構Ｄのツメ（II）によりＡ-ロの位置に運ばれ、分注ピペットＥにより希釈液が再度分注される。   The specimen container that has been transported to the C-ro position is transported to the A-ro position by the claw (II) of the second specimen container transfer mechanism D, and the diluting liquid is dispensed again by the dispensing pipette E. Is done.

希釈液の分注を完了した検体容器は、ベルトＡにより図示しない分析部に搬送され、再度分析が行なわれる。   The sample container that has completed the dispensing of the diluted solution is transported to an analysis unit (not shown) by the belt A and is analyzed again.

ベルトＡ、Ｂ、Ｃの間隔と等しい間隔でツメ（Ｉ）とツメ（II）が設けられているので、Ｂ-ロの位置からＡ-ロの位置へ空容器を移す作業は、Ａ-ロの位置からＣ-ロの位置へ再検用の検体容器を取りに行く作業と兼ねることができ、また、Ｃ-ロの位置からＡ-ロの位置へ再検用の検体容器を移す作業は、Ａ-ロの位置からＢ-ロの位置へ空容器を取りに行く作業と兼ねることができる。その結果、再検用の検体容器を取りに行くための所要時間をなくすことができ、割り込み時間を発生させることなく、自動分析装置の分析周期に合わせた搬送処理が可能になる。   Since claw (I) and claw (II) are provided at an interval equal to the interval between belts A, B, and C, the operation of moving the empty container from the position of B-Ro to the position of A-Ro It can be combined with the operation of taking the sample container for re-examination from the position of C-ro to the position of C-ro, and the operation of moving the sample container for re-examination from the position of C-ro to the position of A-ro -It can be combined with the work of picking up an empty container from position B to position B. As a result, it is possible to eliminate the time required for taking the sample container for retesting, and it is possible to perform a transport process in accordance with the analysis cycle of the automatic analyzer without generating an interruption time.

また、分析部に進んだ検体容器は、その分析内容（分析項目数）によって処理時間に違いが生じるため、搬送ベルトＡが検体容器の貯留空間となり、再希釈分析の割り込みによる処理時間への悪影響も無視できる。   In addition, since the processing time of the sample container that has advanced to the analysis unit varies depending on the analysis content (the number of analysis items), the transport belt A becomes a storage space for the sample container, and adversely affects the processing time due to interruption of re-dilution analysis. Can be ignored.

生化学自動分析装置の検体容器搬送機構に、広く利用できる。   It can be widely used for the specimen container transport mechanism of the biochemical automatic analyzer.
