Description

【０００１】
【発明の属する技術分野】
本発明は、汚染物質の有無を検査するための検査用具に関するものである。
【０００２】
【従来の技術】
食品工場等の衛生管理が要求される場所では、そこで使用される機械や器具をよく洗浄し、その上、タンパク質などの汚染物質が残留していないかどうかを検査する必要がある。従来より、汚染物質の有無を検査するためには、呈色反応を示す試薬液と、綿棒などの採取用器具と、透明な試験容器とを備えた検定用具が用いられる。
【０００３】
タンパク質の有無を検査する場合には、例えば、ビシコニン酸ナトリウムを１％（ｗ/ｖ）、Ｎａ2ＣＯ3を２％（ｗ/ｖ）、酒石酸ナトリウムを０．１６％（ｗ/ｖ）、ＮａＯＨを０．４％（ｗ/ｖ）、さらにＮａＨＣＯ3を０．９５％（ｗ/ｖ）含む水溶液（試薬液Ａ）と、ＣｕＳＯ4・５Ｈ2Ｏを４％（ｗ/ｖ）含む水溶液（試薬液Ｂ）と、綿棒と、透明な試験管とを備えた検査用具が用いられる。
【０００４】
この検査用具は以下のようにして使用される。まず、１mlの試薬液Ａを試薬瓶から試験管に移す。続いて、試薬液Ｂを数滴加えて混合する。この混合試薬液は呈色反応を示す。次に、機械や器具などの調査対象物の表面を綿棒で拭き取って試料を採取し、その綿棒を混合試薬液に漬ける。そして、このまま室温で１５分程度放置し、反応させた後、混合試薬液の色を観察する。ここで、混合試薬液の色が赤紫色に変化すると、タンパク質が存在していることを表す。
【０００５】
【発明が解決しようとする課題】
しかし、従来の検査用具では、収納空間が大きくなりすぎるため、検査現場まで運搬しにくく、また検査現場で携帯しにくい。さらに、従来の検査用具では、試験容器に試薬液を入れる作業を検査現場でしなければならず、操作が面倒である。
それ故、本発明の目的は、運搬及び携帯に便利で、簡単に操作できる検査用具を提供することにある。
【０００６】
【課題を解決するための手段】
本発明の検査用具は、呈色反応を示す試薬液と、試料を採取し試薬液に添加するための綿棒と、透明な試験容器とを備えた検査用具において、前記試験容器が柔軟性材料からなる密封された袋であって、一端部に前記綿棒を出し入れするための出入口を有し内部に１本の綿棒を収容する縦長の綿棒収容部、並びに、この綿棒収容部の他端部側に連接され内部に１回の検査に必要な量の試薬液を収容する試薬液収容部が形設され、前記綿棒収容部と前記試薬液収容部とが、綿棒の先端部を試薬液収容部の方向へ押し込むことにより又は試薬液収容部の袋面を指で押さえ付けて袋内部の圧力を加えることにより柔軟性材料の内面同士が剥離する程度に接着した仮接着部によって仕切られ互いに隔離されたことを特徴としている。
請求項２に係る発明は、請求項１に記載の検査用具において、試薬液が複数の溶液からなり、各溶液を互いに隔離する第二の仮接着部を試験容器に設けたことを特徴とする。
請求項３に係る発明は、請求項１又は２に記載の検査用具において、各々の仮接着部において柔軟性材料の内面同士を剥離可能に接着させるための手段が熱圧着であることを特徴とする。
【０００７】
本発明の検査用具によって汚染物質の有無を検査するには、以下のようにすれば良い。まず、綿棒を試験容器の綿棒収容部からその一端部の出入口を通して取り出し、試料を採取した後、再び試験容器の綿棒収容部内に入れる。続いて、綿棒の先端部を試薬液収容部の方向へ押し込むか、或いは試薬液収容部の袋面を指で押さえ付けて袋内部の圧力を加えることにより、仮接着部の柔軟性材料の内面同士を剥離させて、綿棒を試薬液に漬ける。そして、このまま反応させた後、試薬液の色を観察し、汚染物質の有無を判定する。
【０００８】
本発明の検査用具では、試薬液と綿棒とが試験容器内に収容されて、一つにまとまっている。よって、本発明の検査用具では、収納空間が小さくて済み、運搬及び携帯に便利である。また、一回の検査に必要な量の試薬液が試験容器の試薬液収容部内に既に入っているので、試薬液を入れる作業をする必要が無く、操作が簡単である。さらに、試験容器が柔軟性材料からなるので、破損しにくい。また、試験容器を変形させて、収納空間をより小さくすることも可能である。
【０００９】
試薬液が変質しやすく事前に調整され得ないときには、調整前の複数の溶液をそれぞれ試験容器内に収容しなければならない。このような場合には、試薬液と綿棒とを隔離する仮接着部とは別に、各溶液を互いに隔離する第二の仮接着部を試験容器に設けることによって、各溶液が互いに隔離されるようにすると良い。そして、検査時若しくは検査直前に、この第二の仮接着部を剥離させてそれらの溶液を混合し、試薬液を調製すると良い。また、各仮接着部において柔軟性材料の内面同士を剥離可能に接着させるには、温度条件や圧力条件を適当に調節しながら熱圧着すればよい。
【００１０】
【発明の実施の形態】
本発明の検査用具の第一実施形態を図１に斜視図として示す。また、図１のＡＡ断面図を図２に示す。本実施形態の検査用具１は、一回の検査に必要な量の呈色反応を示す試薬液２と、一個の綿棒３と、試験容器４とからなる。試薬液２は、試験容器４の下部に形設された試薬液収容部内に充填され、綿棒３は、試験容器４の上部に形設された綿棒収容部内に収容されている。
【００１１】
試験容器４は、長方形をした透明な柔軟性フィルムを二枚重ね、周縁部でフィルムの内面同士を接着させることにより、密封された袋となっている。ただし、上端部４ａではフィルムの内面同士を剥離可能に接着させており、そのため上端部４ａを剥離させると綿棒３の出し入れが可能である。また、試薬液２が充填された試薬液収容部と綿棒３が収容された綿棒収容部とは、仮接着部４ｂによって仕切られ互いに隔離されている。仮接着部４ｂでは、上端部４ａと同様に、フィルムの内面同士が剥離可能に接着している。よって、試料を試薬液２に添加する際には、仮接着部４ｂより導入することができる。
【００１２】
試験容器４を構成するフィルムの材質については、透明性、柔軟性、液不透過性、及び菌不透過性を有するものなら、特に限定されない。例えば、ポリスチレンが使用され得る。また、フィルムの内面同士を接着させるには、熱シール機によって熱圧着すると良い。このとき上端部４ａ及び仮接着部４ｂにおいては、温度あるいは圧力を調節して、液密性を保つことができ且つ剥離可能な程度に接着させる。
【００１３】
試薬液２については、検査したい汚染物質の種類に応じて、適当なものを選択すると良い。タンパク質の有無を検査する場合には、試薬液２を、コーマッシー・ブリリアント・ブルー（Coomassie Brilliant Blue, ＣＢＢ）Ｇ−２５０を０．０１％（ｗ/ｖ）、エタノールを４．７％（ｗ/ｖ）、さらにリン酸を８．５％（ｗ/ｖ）含む水溶液にするか、サーバ・ブルー・ジー（Serva Blue Ｇ）を０．０１％（ｗ/ｖ）、エタノールを５．４％（ｗ/ｖ）、さらに８５％（ｗ/ｖ）リン酸を１２％（ｗ/ｖ）含む水溶液にすると良い。これらの水溶液を試薬液２としたときには、先に例示した従来の検査用具の試薬液とは異なり、試薬液を調製する必要が無く、また有害な物質が含まれていないので安全である。さらに、反応時間が短いので、迅速に検査することができる。とりわけ、サーバ・ブルー・ジーを含む水溶液では、反応時間が２分以内で済む。上記二つの水溶液では、一回の検査に必要な量はおよそ１mlである。
【００１４】
本実施形態の検査用具１の使用例として、機械類の表面にタンパク質が存在しているかどうかを検査するための手順を以下に示す。なお、試薬液２としては、上記のサーバ・ブルー・ジーその他の成分を含む水溶液を使用しているものとする。
【００１５】
まず、試験容器４の上端部４ａを剥離させて綿棒収容部内から綿棒３を取り出す。次に、機械や器具などの調査対象物の表面を綿棒３で拭き取って試料を採取し、再び上端部４ａより綿棒３を試験容器４の綿棒収容部内に入れる。続いて、綿棒３を試薬液収容部の方向に押し込む。すると、仮接着部４ｂのフィルムの内面同士が剥離して、綿棒３が試薬液２に漬かる。そして、このまましばらく反応させると良い。ここで、もし試料中にタンパク質が存在しているなら、サーバ・ブルー・ジーがタンパク質のアルギニン基又は芳香族基と結合して、吸光度が変化するため、試薬液２の色が茶色から青色に変わる。よって、試薬液２の色の変化を観察することにより、タンパク質の有無を検査することができる。なお、仮接着部４ｂの剥離は、フィルムの上から試薬液収容部の袋面を指で押さえ付けて圧力を加えることによっても可能である。
【００１６】
本実施形態の検査用具１では、試薬液２と綿棒３とが試験容器４内に収容されて、一つにまとまっている。よって、本実施形態の検査用具では、収納空間が小さくて済み、運搬及び携帯に便利である。また、一回の検査に必要な量の試薬液２が試験容器４内に既に入っているので、試薬液２を入れる作業をする必要が無く、操作が簡単である。さらに、試験容器４が柔軟性フィルムからなるので、破損しにくい。また、試験容器４を変形させて、収納空間をより小さくすることもできる。
【００１７】
本実施形態の検査用具１において、綿棒３を予め滅菌処理しておくと良い。また、綿棒３の綿を湿らせておくと、乾燥した試料でも簡単に採取することができる。一定量の試料を採取できるなら、試薬液２の色の変化程度を観察することにより、汚染物質を定量することも可能である。さらに、試薬液２と綿棒３とを厳重に隔離するために、仮接着部４ｂを二つ以上設けても良い。
【００１８】
本発明の検査用具の第二実施形態を図３に正面図として示す。本実施形態の検査用具１１では、第一実施形態の検査用具１と同様に、試薬液１２と、綿棒１３と、二枚の柔軟性フィルムによって構成された試験容器１４とからなる。しかし、本実施形態の検査用具１１では、仮接着部１４ｂの幅が周縁部における接着部分の幅よりも狭くなっている点で異なる。そのため、第一実施形態の検査用具１よりも仮接着部１４ｂを剥離させるのが容易であり、試薬液１２に外側から圧力を加える（例えば指で押さえる）と、必ず仮接着部１４ｂのみが剥離する。よって、周縁部が剥離して試薬液１２が漏出する心配がない。
【００１９】
本発明の検査用具の第三実施形態を図４に正面図として示す。本実施形態の検査用具２１では、試薬液２２が二種類の溶液からなり、また各溶液を互いに隔離する第二の仮接着部２４ｃが試験容器２４に設けられている。その他は、第一実施形態と同じである。この検査用具２１では、検査時までは各溶液を別々に収容し、検査時には第二の仮接着部２４ｃを剥離させて混合することができる。したがって、本実施形態の検査用具２１は、試薬液２２が変質しやすいため、事前に調整され得ない場合に有効である。
【００２０】
第二の仮接着部２４ｃの剥離は、試料の添加と同時に行っても良いし、試料の添加前に行っても良い。試料添加と同時に行うには、試料採取済みの綿棒２３を試薬液２２の方向に押し込むことによって、仮接着部２４ｂ及び第二の仮接着部２４ｃを続けて剥離させる。試料添加前に行うには、試薬液２２に指で圧力を加えることによって第二の仮接着部２４ｃをまず剥離させて、試薬液を調製した後に、綿棒２３で押し込むか指で圧力を加えるかして、仮接着部２４ｂを剥離させる。なお、図３の検査用具１１の仮接着部１４ｂのように、仮接着部２４ｂ及び第二の仮接着部２４ｃの幅を狭くして剥離し易くしても良い。

[0005]
[Problems to be solved by the invention]
However, with conventional inspection tools, the storage space becomes too large, making it difficult to transport to the inspection site and to carry it at the inspection site. Furthermore, in the conventional inspection tool, the operation | work which puts a reagent liquid in a test container has to be done at an inspection field, and operation is troublesome.
SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an inspection tool that is convenient for carrying and carrying and can be easily operated.
[0006]
[Means for Solving the Problems]
Testing tool of the present invention, a reagent solution showing a color reaction, and swabs for addition to the reagent solution a sample was taken, in the inspection tool and a transparent test container, said test container of flexible material A vertically long swab accommodating portion that has an inlet / outlet for inserting / removing the swab at one end and accommodates one swab inside, and on the other end side of the swab accommodating portion A reagent solution storage unit that is connected and stores a reagent solution in an amount necessary for one test is formed, and the swab storage unit and the reagent solution storage unit connect the tip of the swab to the reagent solution storage unit. By pressing in the direction or pressing the bag surface of the reagent solution storage part with a finger and applying pressure inside the bag, the inner surfaces of the flexible material are separated from each other and separated from each other by a temporary bonding part. It is characterized by that.
The invention according to claim 2 is characterized in that, in the inspection tool according to claim 1, the reagent solution is composed of a plurality of solutions, and a second temporary bonding portion for isolating each solution from each other is provided in the test container. .
The invention according to claim 3 is characterized in that, in the inspection tool according to claim 1 or 2, the means for adhering the inner surfaces of the flexible materials to each other at each temporary bonding portion is thermocompression bonding. To do.
[0007]
In order to inspect the presence or absence of contaminants with the inspection tool of the present invention, the following may be performed. First, swab was removed through entrance of one end portion of the swab containing portion of the test vessel, after collecting the sample, placed again in the swab containing portion of the test vessel. Subsequently, the inner surface of the flexible material of the temporary bonding portion is formed by pushing the tip of the cotton swab in the direction of the reagent solution storage portion or pressing the bag surface of the reagent solution storage portion with a finger and applying pressure inside the bag. Separate each other and dip a cotton swab in the reagent solution . Its to and reacted in this state, by observing the color of the reagent solution, determines the presence or absence of contaminants.
[0008]
In the inspection tool of the present invention, the reagent solution and the cotton swab are accommodated in the test container and are united. Therefore, the inspection tool of the present invention requires a small storage space and is convenient for transportation and carrying. Further, since the reagent solution in an amount required for one test is already in the reagent liquid storage portion of the test vessel, it is not necessary to work to put the reagent solution, the operation is simple. Furthermore, since the test container is made of a flexible material, it is difficult to break. It is also possible to make the storage space smaller by deforming the test container.
[0009]
When the reagent solution is likely to change in quality and cannot be adjusted in advance, a plurality of solutions before adjustment must be stored in test containers. In such a case, apart from the temporary bonding part that separates the reagent solution and the swab , a second temporary bonding part that separates the solutions from each other is provided in the test container so that the solutions are separated from each other. It is good to make it. Then, at the time of inspection or immediately before the inspection, it is preferable to prepare a reagent solution by peeling off the second temporary adhesion portion and mixing the solutions. Moreover, what is necessary is just to carry out thermocompression bonding, adjusting temperature conditions and pressure conditions suitably, in order to adhere the inner surfaces of a flexible material in each temporary adhesion part so that peeling is possible.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the inspection tool of the present invention is shown as a perspective view in FIG. FIG. 2 is a cross-sectional view taken along the line AA in FIG. The inspection tool 1 of the present embodiment includes a reagent solution 2 that exhibits a color reaction of an amount necessary for one inspection, a single swab 3, and a test container 4. Reagent solution 2 is filled in Katachi設reagent liquid receptacle at the bottom of the test container 4, swab 3 is accommodated in Katachi設been swab receptacle on top of the test container 4.
[0011]
The test container 4 is a sealed bag by stacking two rectangular transparent flexible films and bonding the inner surfaces of the films at the periphery. However, at the upper end portion 4a, the inner surfaces of the film are detachably bonded, and therefore the cotton swab 3 can be taken in and out when the upper end portion 4a is peeled off. Further, the reagent solution storage portion filled with the reagent solution 2 and the cotton swab storage portion in which the cotton swab 3 is stored are separated from each other by the temporary bonding portion 4b. In the temporary adhesion part 4b, like the upper end part 4a, the inner surfaces of a film are adhere | attached so that peeling is possible. Therefore, when adding a sample to the reagent solution 2, it can introduce | transduce from the temporary adhesion part 4b.
[0012]
About the material of the film which comprises the test container 4, if it has transparency, a softness | flexibility, liquid impermeability, and bacteria impermeability, it will not specifically limit. For example, polystyrene can be used. Moreover, in order to adhere the inner surfaces of the films, it is preferable to perform thermocompression bonding with a heat sealing machine. At this time, the upper end portion 4a and the temporary bonding portion 4b are bonded to such an extent that the liquid-tightness can be maintained and the separation can be performed by adjusting the temperature or pressure.
[0013]
About the reagent liquid 2, it is good to select an appropriate thing according to the kind of contaminant to test | inspect. When examining the presence or absence of protein, the reagent solution 2 is 0.01% (w / v) of Coomassie Brilliant Blue (CBB) G-250 and 4.7% (w / v) of ethanol. v) Further, an aqueous solution containing 8.5% (w / v) phosphoric acid is added, or 0.01% (w / v) of Serva Blue G and 5.4% of ethanol ( w / v) and an aqueous solution containing 85% (w / v) phosphoric acid 12% (w / v). When these aqueous solutions are used as the reagent solution 2, unlike the reagent solution of the conventional test tool exemplified above, it is not necessary to prepare the reagent solution and it is safe because it does not contain harmful substances. Furthermore, since the reaction time is short, it can be inspected quickly. In particular, with an aqueous solution containing Server Blue G, the reaction time is less than 2 minutes. In the above two aqueous solutions, the amount required for one test is approximately 1 ml.
[0014]
As a usage example of the inspection tool 1 of the present embodiment, a procedure for inspecting whether a protein is present on the surface of machinery is shown below. In addition, as the reagent solution 2, it is assumed that an aqueous solution containing the above-mentioned Server Blue Gee and other components is used.
[0015]
First, the upper end 4a of the test container 4 is peeled off, and the swab 3 is taken out from the inside of the swab accommodating portion. Then, samples were taken by wiping the surface of the inspection object, such as a machine or instrument with a cotton swab 3, put the swab 3 in swab containing portion of the test vessel 4 from the upper end 4a again. Subsequently, the cotton swab 3 is pushed in the direction of the reagent solution storage unit . Then, the inner surfaces of the film of the temporary bonding portion 4 b are peeled off, and the cotton swab 3 is immersed in the reagent solution 2. And it is better to react for a while. Here, if protein is present in the sample, Server Blue G binds to the protein's arginine group or aromatic group and the absorbance changes, so the color of reagent solution 2 changes from brown to blue. change. Therefore, the presence or absence of protein can be inspected by observing the color change of the reagent solution 2. The temporary adhesive portion 4b can be peeled off by pressing the bag surface of the reagent solution storage portion with a finger from above the film.
[0016]
In the inspection tool 1 of the present embodiment, the reagent solution 2 and the cotton swab 3 are accommodated in the test container 4 and gathered together. Therefore, the inspection tool of this embodiment requires a small storage space and is convenient for transportation and carrying. In addition, since the reagent solution 2 in an amount necessary for one test is already in the test container 4, there is no need to perform the operation of putting the reagent solution 2 and the operation is simple. Furthermore, since the test container 4 consists of a flexible film, it is hard to be damaged. Moreover, the storage space can be made smaller by deforming the test container 4.
[0017]
In the inspection tool 1 of this embodiment, the cotton swab 3 may be sterilized in advance. Further, if the cotton swab 3 is moistened, a dry sample can be easily collected . If the sample one quantitative can be collected, by observing the degree of change in color of the reagent solution 2, it is possible to quantify the contaminants. Further, in order to strictly separate the reagent solution 2 and the cotton swab 3, two or more temporary bonding portions 4b may be provided.
[0018]
A second embodiment of the inspection tool of the present invention is shown as a front view in FIG. In the inspection tool 11 of the present embodiment, as in the inspection tool 1 of the first embodiment, the reagent liquid 12, the cotton swab 13, and the test container 14 composed of two flexible films are included. However, the inspection tool 11 of the present embodiment is different in that the width of the temporary bonding portion 14b is narrower than the width of the bonding portion in the peripheral portion. Therefore, it is easier to peel the temporary adhesion portion 14b than the inspection tool 1 of the first embodiment. When pressure is applied to the reagent solution 12 from the outside (for example, pressing with a finger), only the temporary adhesion portion 14b is surely peeled off. To do. Therefore, there is no fear that the peripheral edge peels off and the reagent solution 12 leaks out.
[0019]
FIG. 4 shows a front view of a third embodiment of the inspection tool of the present invention. In the inspection tool 21 of the present embodiment, the reagent solution 22 is composed of two types of solutions, and a second temporary bonding portion 24 c that isolates the solutions from each other is provided in the test container 24. Others are the same as the first embodiment. In this inspection tool 21, each solution can be stored separately until the time of inspection, and the second temporary bonding portion 24c can be peeled off and mixed at the time of inspection. Therefore, the inspection tool 21 of the present embodiment is effective when the reagent solution 22 is easily altered and cannot be adjusted in advance.
[0020]
The peeling of the second temporary bonding portion 24c may be performed simultaneously with the addition of the sample, or may be performed before the addition of the sample. In order to perform simultaneously with the sample addition, the sampled cotton swab 23 is pushed in the direction of the reagent solution 22 to continuously peel off the temporary adhesion portion 24b and the second temporary adhesion portion 24c. In order to perform the sample before adding the sample, whether the second temporary adhesive portion 24c is first peeled off by applying pressure to the reagent solution 22 with a finger, and then the reagent solution is prepared. Then, the temporary bonding portion 24b is peeled off. In addition, like the temporary bonding part 14b of the test | inspection tool 11 of FIG. 3, you may make it easy to peel by narrowing the width | variety of the temporary bonding part 24b and the 2nd temporary bonding part 24c.
[0021]
