以下、本発明の一実施形態を添付図面を用いて説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

図1において、1は微生物濃度調整器で、その液体流入口2には、ポンプ3、切替弁4を介して培養液収納容器5が接続されている。また、切替弁4には、切替弁6を介して洗浄液収納容器7と試料液収納容器8が選択的に接続されている。   In FIG. 1, reference numeral 1 denotes a microorganism concentration adjuster, and a culture solution storage container 5 is connected to a liquid inlet 2 via a pump 3 and a switching valve 4. Further, a cleaning liquid storage container 7 and a sample liquid storage container 8 are selectively connected to the switching valve 4 via a switching valve 6.

さらに、微生物濃度調整器1の液体流出口9には、切替弁10を介して培養液収納容器11が接続されている。また、切替弁10には、切替弁12を介して、培養液収納容器5と廃棄槽13が選択的に接続されている。   Furthermore, a culture solution storage container 11 is connected to the liquid outlet 9 of the microorganism concentration adjuster 1 via a switching valve 10. Further, the culture solution storage container 5 and the waste tank 13 are selectively connected to the switching valve 10 via the switching valve 12.

さて、本実施形態における特徴は、微生物濃度調整器1を図3に示す構成としたものである。すなわち、液体流入口2と液体流出口9の間には液体流路14が設けられ、この液体流路14には、その液体流入口2から液体流出口9に向けて、12対の微生物捕獲電極対15a、15b、15c、15d、15e、15f、15g、15h、15i、15j、15k、15lが直線状に配置されている。   The feature of the present embodiment is that the microorganism concentration adjuster 1 is configured as shown in FIG. That is, a liquid channel 14 is provided between the liquid inlet 2 and the liquid outlet 9, and 12 pairs of microorganisms are captured in the liquid channel 14 from the liquid inlet 2 toward the liquid outlet 9. The electrode pairs 15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h, 15i, 15j, 15k, 15l are linearly arranged.

これら12対の微生物捕獲電極対15a〜15lは、それぞれ櫛歯状の電極を所定のギャップを介して対向させた構成となっている。   Each of these 12 pairs of microorganism capture electrodes 15a to 15l has a configuration in which comb-like electrodes are opposed to each other with a predetermined gap therebetween.

しかし、これらの微生物捕獲電極対15a〜15lは、以下に説明する微生物の捕獲個数に応じて、対向する電極間のギャップと、対向する電極の大きさ(長さ)が異ならせている。   However, in these microorganism capture electrode pairs 15a to 15l, the gap between the opposed electrodes and the size (length) of the opposed electrodes are varied according to the number of captured microorganisms described below.

具体的には、微生物捕獲電極対15aは微生物を1×10E06(10の6乗)、15bは微生物を1×10E06(10の6乗)、15cは微生物を3×10E06(10の6乗)、15dは微生物を5×10E06(10の6乗)、15eは微生物を1×10E07(10の7乗)、15fは微生物を1×10E07(10の7乗)、15gは微生物を3×10E07(10の7乗)、15hは微生物を5×10E07(10の7乗)、15iは微生物を1×10E08(10の8乗)、15jは微生物を1×10E08(10の8乗)、15kは微生物を3×10E08(10の8乗)、15lは微生物を5×10E08(10の8乗)を捕獲する構成となっている。   Specifically, the microorganism capture electrode pair 15a is 1 × 10E06 (10 6), 15b is 1 × 10E06 (10 6), and 15c is 3 × 10E06 (10 6). 15d is 5 × 10E06 (10 6), 15e is 1 × 10E07 (10 7), 15f is 1 × 10E07 (10 7), 15g is 3 × 10E07 (10 to the seventh power), 15h for microorganisms 5 × 10E07 (10 to the seventh power), 15i for microorganisms 1 × 10E08 (10 to the eighth power), 15j for microorganisms 1 × 10E08 (10 to the eighth power), 15k Is configured to capture 3 × 10E08 (10 8) of microorganisms, and 15 l is configured to capture 5 × 10E08 (10 8) of microorganisms.

そして、このような微生物の捕獲をさせるために、これらの微生物捕獲電極対15a〜15lには、それぞれ図2、図3で示すように、ドライブ回路16を介して、電圧供給手段17から電圧が供給される構成となっている。   In order to capture such microorganisms, a voltage is supplied to these microorganism capture electrode pairs 15a to 15l from the voltage supply means 17 via the drive circuit 16 as shown in FIGS. It is a configuration to be supplied.

すなわち、電圧供給手段17は、希望する微生物濃度を設定する入力部18と、この入力部18に接続された制御部19と、この制御部19に接続された表示部20と、これらに電圧を供給する電源部21とにより構成されている。   That is, the voltage supply means 17 includes an input unit 18 for setting a desired microorganism concentration, a control unit 19 connected to the input unit 18, a display unit 20 connected to the control unit 19, and a voltage applied thereto. It is comprised by the power supply part 21 to supply.

また、ドライブ回路16は、制御部22と、この制御部22に接続された捕獲電圧供給部23、および測定電圧供給部24と、前記捕獲電圧供給部23と微生物捕獲電極対15a間に設けたスイッチング手段25と、前記測定電圧供給部24と微生物捕獲電極対15a間に設けたスイッチング手段26とにより構成されている。   The drive circuit 16 is provided between the control unit 22, the capture voltage supply unit 23 and the measurement voltage supply unit 24 connected to the control unit 22, and the capture voltage supply unit 23 and the microorganism capture electrode pair 15a. The switching means 25 and the switching means 26 provided between the measurement voltage supply unit 24 and the microorganism capturing electrode pair 15a are configured.

なお、ドライブ回路16は、微生物捕獲電極対15a〜15lとも共通のものを用いている。ただし、入力部18によって設定した微生物の捕獲個数に応じて、これらの微生物捕獲電極対15a〜15lに選択的に電源供給が行われる構成となっている。   Note that the drive circuit 16 is common to the microorganism capture electrode pairs 15a to 15l. However, according to the number of microorganisms captured by the input unit 18, power is selectively supplied to these microorganism capture electrode pairs 15a to 15l.

以上の構成において、図5は、微生物濃度調整器1の液体流路14に培養液収納容器5から微生物を含む培養液を供給する状態を示している。   In the above configuration, FIG. 5 shows a state in which a culture solution containing microorganisms is supplied from the culture solution storage container 5 to the liquid channel 14 of the microorganism concentration controller 1.

この場合、まず、電圧供給手段17の電源スイッチ27(図2には、図示していないが電源部21に接続されているものである)を入れ、図2に示す全ての微生物捕獲電極対15a〜15lにドライブ回路16を介して電圧を供給する。   In this case, first, a power switch 27 (not shown in FIG. 2 but connected to the power supply unit 21) of the voltage supply means 17 is turned on, and all the microorganism capture electrode pairs 15a shown in FIG. A voltage is supplied to ˜15 l via the drive circuit 16.

また、ポンプ3および切替弁4、10、12に通電し、これにより、培養液収納容器5から微生物を含む培養液を、切替弁4、ポンプ3を介して微生物濃度調整器1の液体流路14に供給し、また、余分な培養液は、切替弁10、12を介して、培養液収納容器5に戻すこととする。   In addition, the pump 3 and the switching valves 4, 10, 12 are energized, whereby the culture solution containing microorganisms is transferred from the culture solution storage container 5 via the switching valve 4 and the pump 3 to the liquid flow path of the microorganism concentration regulator 1. 14 and the excess culture solution is returned to the culture solution storage container 5 via the switching valves 10 and 12.

この結果、全ての微生物捕獲電極対15a〜15lに、上述した設定個数の微生物がそれぞれ捕獲されることとなる。   As a result, the set number of microorganisms described above are captured by all the microorganism capturing electrode pairs 15a to 15l.

この場合、ドライブ回路16においては、捕獲電圧供給部23からスイッチング手段25を介して、微生物捕獲電極対15a〜15lに微生物捕獲のための3MHzの電圧が供給され、これにより、周知の誘電泳動により、微生物捕獲電極対15a〜15lに設定個数通りの微生物が捕獲される。   In this case, in the drive circuit 16, a voltage of 3 MHz for capturing microorganisms is supplied from the capture voltage supply unit 23 via the switching means 25 to the microorganism capture electrode pairs 15 a to 15 l, thereby performing known dielectrophoresis. The set number of microorganisms are captured by the microorganism capture electrode pairs 15a to 15l.

なお、それぞれの微生物捕獲電極対15a〜15lで設定個数通りの微生物が捕獲された否かを測定するために、捕獲電圧供給部23を一時停止し、測定電圧供給部24から800kHzの測定電圧をスイッチング手段26を介して、微生物捕獲電極対15a〜15lに測定電圧を供給し、測定を行う。   In addition, in order to measure whether or not a set number of microorganisms are captured by each of the microorganism capture electrode pairs 15a to 15l, the capture voltage supply unit 23 is temporarily stopped, and a measurement voltage of 800 kHz is applied from the measurement voltage supply unit 24. A measurement voltage is supplied to the microorganism capture electrode pairs 15a to 15l via the switching means 26 to perform measurement.

そして、この測定により、全ての微生物捕獲電極対15a〜15lにおいて、設定個数通りの微生物が捕獲されると、入力部18により、培養液収納容器11に収納させる微生物濃度を設定する。   Then, by this measurement, when the set number of microorganisms are captured in all the microorganism capture electrode pairs 15a to 15l, the input unit 18 sets the concentration of microorganisms to be stored in the culture solution storage container 11.

すると、図6に示すごとく、まず、切替弁4の通電を断ち、切替弁6に通電し、これにより、洗浄液収納容器7から洗浄液として純水を切替弁6、切替弁4、ポンプ3を介して微生物濃度調整器1の液体流路14に供給する。そして、切替弁12の通電を断つ。   Then, as shown in FIG. 6, first, the switching valve 4 is turned off and the switching valve 6 is turned on. As a result, pure water is supplied from the cleaning liquid storage container 7 as the cleaning liquid via the switching valve 6, the switching valve 4, and the pump 3. And supplied to the liquid flow path 14 of the microorganism concentration controller 1. Then, the switching valve 12 is turned off.

その結果、液体流路14内において、微生物捕獲電極対15a〜15lで捕獲されていない微生物は切替弁10、12を介して廃棄槽13に排出される。   As a result, in the liquid flow path 14, the microorganisms that are not captured by the microorganism capture electrode pairs 15 a to 15 l are discharged to the waste tank 13 through the switching valves 10 and 12.

また、液体流路14内において、微生物捕獲電極対15a〜15lに捕獲されている微生物は、栄養素を全く含まない純水が周りを覆ったことで、この液体流路14内において、増殖することはない。   In addition, the microorganisms captured by the microorganism capture electrode pairs 15a to 15l in the liquid channel 14 grow in the liquid channel 14 because the pure water not containing any nutrients covers the surroundings. There is no.

つまり、この状態においては、液体流路14内において、微生物捕獲電極対15a〜15lで設定された通りの微生物が、存在している状態となっている。   That is, in this state, microorganisms as set by the microorganism capture electrode pairs 15a to 15l exist in the liquid flow path 14.

ここで、この部分について、さらに詳細に説明すると、通電された微生物捕獲電極対15a〜15lは、上述のごとく、個々に設定された通りの個数の微生物を捕獲しているが、入力部18によって設定された範囲外の微生物捕獲電極対15a〜15lは、その通電が解かれ、微生物の捕獲も開放され、この開放された微生物は、液体流路14内に供給される純水とともに廃棄槽13に向けて排出される。   Here, this part will be described in more detail. The energized microorganism capturing electrode pairs 15a to 15l capture the number of microorganisms as set individually as described above. The microorganism capture electrode pairs 15a to 15l outside the set range are de-energized and the capture of microorganisms is also released. The opened microorganisms are disposed in the waste tank 13 together with pure water supplied into the liquid flow path 14. It is discharged toward

そこで、この状態において、次に図7のごとく、切替弁6の通電を断ち、これにより、試料液収納容器8からの試料を切替弁6、4、ポンプ3を介して微生物濃度調整器1の液体流路14に試料液(例えば、純水または設定された試料液)を供給し、この時に微生物捕獲電極対15a〜15lへの通電を絶ち、切替弁10の通電を絶つ。   Therefore, in this state, as shown in FIG. 7, next, the energization of the switching valve 6 is cut off, so that the sample from the sample solution storage container 8 is supplied to the microorganism concentration regulator 1 via the switching valves 6, 4 and the pump 3. A sample solution (for example, pure water or a set sample solution) is supplied to the liquid flow path 14, and at this time, the energization of the microorganism capture electrode pairs 15a to 15l is stopped, and the switching valve 10 is turned off.

すると、微生物捕獲電極対15a〜15lによって捕獲された設定個数通りの微生物が切替弁10を介して、培養液収納容器11に試料液とともに流入することとなる。   Then, a set number of microorganisms captured by the microorganism capture electrode pairs 15a to 15l flow into the culture solution storage container 11 through the switching valve 10 together with the sample solution.

この時、培養液収納容器11内に流入した微生物の個数は、入力部18によって設定された通りのものとなり、これが、培養液収納容器11内に供給されるので、この培養液収納容器11内における微生物濃度は、設定された通りのものとなる。   At this time, the number of microorganisms flowing into the culture solution storage container 11 is as set by the input unit 18 and is supplied into the culture solution storage container 11. The microbial concentration in is as set.

なお、微生物捕獲電極対15a〜15lの設定として、微生物捕獲電極対15aは微生物を1×10E06(10の6乗)、15bは微生物を1×10E06(10の6乗)、15cは微生物を3×10E06(10の6乗)、15dは微生物を5×10E06(10の6乗)、15eは微生物を1×10E07(10の7乗)、15fは微生物を1×10E07(10の7乗)、15gは微生物を3×10E07(10の7乗)、15hは微生物を5×10E07(10の7乗)、15iは微生物を1×10E08(10の8乗)、15jは微生物を1×10E08(10の8乗)、15kは微生物を3×10E08(10の8乗)、15lは微生物を5×10E08(10の8乗)とした理由は、これらの通電、あるいは通電停止を組み合わせれば、複数の設定値が簡単に得られるからである。   The microorganism capture electrode pairs 15a to 15l are set as follows: the microorganism capture electrode pair 15a is 1 × 10E06 (10 6), 15b is 1 × 10E06 (10 6), and 15c is 3 microorganisms. × 10E06 (10 6), 15d is 5 × 10E06 (10 6), 15e is 1 × 10E07 (10 7), 15f is 1 × 10E07 (10 7) 15g is 3 × 10E07 (10 to the 7th power), 15h is 5 × 10E07 (10 to the 7th power), 15i is 1 × 10E08 (10 to the 8th power), 15j is 1 × 10E08. (10 to the 8th power), 15k for microorganisms 3 × 10E08 (10 to the 8th power), and 15l for microorganisms 5 × 10E08 (10 to the 8th power). This is because a plurality of set values can be easily obtained.

例えば、捕獲する微生物の個数を9×10E06(10の6乗)個とする場合には、微生物捕獲電極対15b〜15dの3つに通電し、他は非通電状態とすればよい。   For example, when the number of microorganisms to be captured is 9 × 10E06 (10 6), three of the microorganism capture electrode pairs 15b to 15d may be energized, and the other may be in a non-energized state.

また、捕獲する微生物の個数を9×10E07(10の7乗)個とする場合には、微生物捕獲電極対15f〜15hの3つに通電し、他は非通電状態とすればよい。   Further, when the number of microorganisms to be captured is 9 × 10E07 (10 to the seventh power), the three microorganism capture electrode pairs 15f to 15h may be energized and the others may be in a non-energized state.

このように、本実施形態においては、複数設けた微生物捕獲電極対15a〜15lのギャップ間の距離や大きさを異ならせると共に、選択的な通電を行うことで、微生物濃度を希望する濃度に簡単に調整することができるものとなる。   As described above, in the present embodiment, the distance and size between the gaps of the plurality of microorganism capture electrode pairs 15a to 15l that are provided are made different, and selective energization is performed to easily reduce the microorganism concentration to a desired concentration. Can be adjusted.
