Description

本発明は、付着菌を採取するための菌採取用具及び該菌採取用具を用いた菌採取方法に関する。   TECHNICAL FIELD The present invention relates to a bacteria collecting tool for collecting adherent bacteria and a bacteria collecting method using the bacteria collecting tool.

空気中に浮遊している細菌や真菌が、医薬品や食品、電子機器製品等の製造機械、調理器具等に付着堆積し、その堆積した箇所に触れた手指が、生産コンベアなど製品が直接触れる物を再度触ることにより菌汚染を拡げる。また、その手指が直接製品に触れた場合は、製品の菌汚染リスクがかなり高くなる。空中浮遊菌の定期的な検査ならびに付着菌の検査は、製品の微生物汚染原因がどこに存在するか顕在化し、リスクの低減に有効な対策の一つである。   Bacteria and fungi floating in the air adhere to and accumulate on pharmaceuticals, foods, manufacturing machines for electronic device products, cooking utensils, etc., and the fingers touching the accumulated parts directly touch the product such as a production conveyor. Spread the bacterial contamination by touching again. In addition, if the fingers directly touch the product, the risk of bacterial contamination of the product is considerably increased. Regular inspection of airborne bacteria and inspection of adherent bacteria are one of the effective measures to reduce the risk by revealing where the cause of microbial contamination of the product is.

付着菌の検査方法としては、天井、壁、床、又は施設内に設置された高所の空調機器、配管、ダクト、商品等を搬送するベルトコンベア、あるいは医薬品、食品、電子機器製品などの製造機械、空調機器やこれらの内側、裏側などを滅菌された綿棒で拭き取り、拭き取った付着物を培養して菌の発生状態を検査する拭取検査が一般的である。   As a method for inspecting adherent bacteria, air conditioners at ceilings, walls, floors, or at high places installed in facilities, pipes, ducts, belt conveyors that convey products, etc., or manufacturing of pharmaceutical products, foods, electronic device products, etc. Generally, a machine, an air conditioner, and the inside and the back of the machine are wiped with a sterilized cotton swab, and the adhered matter that has been wiped is cultured to inspect the generation state of bacteria.

拭取検査は、検査対象が広範囲になることがあり、また1つの検査対象に対して複数個所から拭取検査を行うこともある。また、天井や高所設備に対して拭取検査をする場合には、脚立などの足場を使用して移動しながら作業しなければならず、作業者が誤って落下する危険性がある。さらに、食品製造機械などには加工用に刃(カッター)が取り付けられているものもあり、作業者が誤って手を切ってしまうなどの危険を伴うことがあるため、検査用具の改善が求められていた。   The wiping inspection may cover a wide range of inspection targets, and one inspection target may be wiped from a plurality of locations. Further, when performing a wiping inspection on a ceiling or a facility at a high place, it is necessary to use a scaffold such as a stepladder to move while working, and there is a risk that an operator may accidentally fall. Furthermore, some food manufacturing machines have blades (cutters) attached to them for processing, which can be dangerous for workers to accidentally cut their hands. It was being done.

そこで、医療機関、食品製造施設、医薬品製造所等での微生物検査に使用できる、持ち運び容易で、拭取り箇所の微生物を捕獲し易い、微生物簡易拭き取り器具が提案されている(例えば、特許文献1)。   Therefore, a simple microorganism wiping device has been proposed that can be used for microbiological testing in medical institutions, food manufacturing facilities, pharmaceutical manufacturing plants, etc., is easy to carry, and easily captures microorganisms at the wiping location (for example, Patent Document 1). ).

特許文献1には、密封容器本体、蓋体、蓋体に基部が支持され容器本体内に挿入されるステック、ステック先端に支持され希釈液を含侵させた拭き取り部を備えた微生物簡易拭き取り器具が開示されている。使用時には容器本体から蓋体を取り外し、拭き取り部を検査箇所に当てて拭き取ったのち、容器本体内に収容して蓋体を閉めて密封する。これにより、検査対象からの微生物の回収が容易で作業性もよく、また容器本体には希釈液等は入っておらず捕獲後の微生物が希釈されないため、微生物を確実に検出できる。そして、ステックが伸縮可能であるため、拭き取り箇所に応じてステックを伸び縮みさせて使用できるものである。   Patent Document 1 discloses a microorganism simple wiping device including a sealed container body, a lid, a stick whose base is supported by the lid and is inserted into the container body, and a wiping part supported by the tip of the stick and impregnated with a diluent. Is disclosed. At the time of use, the lid is removed from the container body, the wiping part is applied to the inspection location to wipe it off, and then the container is housed in the container body and the lid is closed and sealed. As a result, the microorganisms can be easily detected from the test object and the workability is good, and since the diluent is not contained in the container body and the captured microorganisms are not diluted, the microorganisms can be reliably detected. Since the stick can be expanded and contracted, the stick can be expanded and contracted according to the wiping location.

しかしながら、特許文献1の微生物簡易拭き取り器具では、高所にある空調機器や配管、ダクト、ベルトコンベアなどの表面や内側、裏側まで届くほどに器具を伸ばして使用することはできない。脚立等の足場を用いて拭き取り作業を行ってもよいが、その場合には作業者が誤って足場から落下する危険性を伴うため、好ましいとは言えない。また、製造機械の内側の拭取検査を行う場合に、誤って加工用の刃(カッター)で手を切る危険性があり、安全性が十分であるとは言えない。   However, with the simple microorganism wiping device of Patent Document 1, the device cannot be extended and used until it reaches the surface, the inside, and the back of air conditioners, pipes, ducts, belt conveyors, etc. at high places. The wiping work may be performed using a scaffold such as a stepladder, but in that case, it is not preferable because there is a risk that the worker will accidentally fall from the scaffold. In addition, when performing a wiping test on the inside of a manufacturing machine, there is a risk of accidentally cutting a hand with a processing blade (cutter), and it cannot be said that safety is sufficient.

<菌採取用具>
図1(a)は、本発明の菌採取用具1の第一の実施形態、図1(b)は、本発明の菌採取用具1の第二の実施形態、図1(c)は、本発明の菌採取用具1の第三の実施形態を示している。
<Tools for collecting bacteria>
1 (a) is a first embodiment of the bacteria collecting tool 1 of the present invention, FIG. 1 (b) is a second embodiment of the bacteria collecting tool 1 of the present invention, and FIG. 1 (c) is a book. The 3rd embodiment of the bacteria collection tool 1 of the invention is shown.

(実施形態1)
図1(a)に示す本発明の菌採取用具1は、作業者が菌採取用具1を使用するときに把持する把持部10と、前記把持部10の管内に挿入し、伸縮自在な複数の可動部11(11a〜11e)と、前記可動部11eの先端部に固定具12を介して固定した綿棒13とから構成される。
(Embodiment 1)
The bacteria collecting tool 1 of the present invention shown in FIG. 1 (a) includes a grip portion 10 to be gripped by an operator when the bacteria collecting tool 1 is used, and a plurality of expandable and contractible members inserted into the tube of the grip portion 10. The movable part 11 (11a to 11e) and a cotton swab 13 fixed to the tip of the movable part 11e via a fixture 12.

使用時には、把持部10内に挿入した可動部11を引き出して任意の長さに調節し、把持部10を把持して、菌採取用具1の先端部に固定した綿棒13を検査対象に押し当て、擦るように動かすことで検査対象の菌を採取する。これにより、脚立等の足場を使用することなく床面にいながら拭取検査ができるため、足場等から落下して怪我をする危険性がなく、また足場の設置や移動に時間をとられることなく短時間で拭取検査ができる。さらに、伸長時に可撓性を有するため、検査対象に擦り付け易く、効率的に採取することができる。検査対象は、後述の菌採取方法で詳細に説明する。   At the time of use, the movable part 11 inserted into the grip part 10 is pulled out and adjusted to an arbitrary length, the grip part 10 is gripped, and the swab 13 fixed to the tip part of the bacteria collection tool 1 is pressed against the inspection target. , Collect the bacterium to be inspected by moving it by rubbing. This allows you to perform a wiping test while you are on the floor without using a scaffolding such as a stepladder, so there is no risk of injury from falling from the scaffolding, and it takes time to install or move the scaffolding. It can be wiped off in a short time. Further, since it has flexibility when extended, it can be easily rubbed against the test object and can be collected efficiently. The inspection target will be described in detail in the method for collecting bacteria described below.

把持部10は中空の円筒状部材であり、その内側に把持部10と実質的に同心の可動部11を複数収容している。把持部10の内径は可動部11aの外径にほぼ等しく、同様に、可動部11aの内径は可動部11bの外径にほぼ等しく、可動部11bの内径は可動部11cの外径にほぼ等しく、可動部11cの内径は可動部11dの外径にほぼ等しく、可動部11dの内径は可動部11eの外径にほぼ等しい。これにより、把持部10を把持した状態で可動部11(11a〜11e)を出し入れすることで、菌採取用具1の全長を調節できる。   The grip portion 10 is a hollow cylindrical member, and accommodates a plurality of movable portions 11 that are substantially concentric with the grip portion 10 inside thereof. The inner diameter of the grip portion 10 is substantially equal to the outer diameter of the movable portion 11a, similarly, the inner diameter of the movable portion 11a is substantially equal to the outer diameter of the movable portion 11b, and the inner diameter of the movable portion 11b is substantially equal to the outer diameter of the movable portion 11c. The inner diameter of the movable portion 11c is substantially equal to the outer diameter of the movable portion 11d, and the inner diameter of the movable portion 11d is substantially equal to the outer diameter of the movable portion 11e. Accordingly, by moving the movable part 11 (11a to 11e) in and out with the gripping part 10 being gripped, the entire length of the bacteria collection tool 1 can be adjusted.

上述した菌採取用具1は、可動部が5段階のものについて説明したが、本発明はこれに限定されない。本発明の菌採取用具1の長さは、特に限定されないが、可動部11を把持部10内に全て挿入し収容した時の長さが20cm〜25cmであり、最大まで可動部11を伸ばした時の長さが1.5m〜5mが適当である。収容時の長さが20cm〜25cm程度であれば、嵩張ることがなく収納できる。また、最大長さが1.5m〜5mであれば、高所の検査対象に対しても作業者の操作性を低下させることなく狙った箇所に綿棒を押し当てることができる。より好ましくは、収納時の長さが20cm〜23cm、最大伸長時の長さが1.5m〜3mである。   The bacteria collection tool 1 described above has five movable parts, but the present invention is not limited to this. The length of the bacteria collection tool 1 of the present invention is not particularly limited, but the length when the movable part 11 is completely inserted and housed in the grip part 10 is 20 cm to 25 cm, and the movable part 11 is extended to the maximum. A time length of 1.5 to 5 m is suitable. If the length when stored is about 20 cm to 25 cm, it can be stored without being bulky. Moreover, if the maximum length is 1.5 m to 5 m, the swab can be pressed against a target location even at a high-altitude inspection target without deteriorating the operability of the operator. More preferably, the stored length is 20 cm to 23 cm, and the maximum stretched length is 1.5 m to 3 m.

把持部10及び可動部11の材料としては、伸縮動作や擦過動作に耐えうる強度を有し、万が一菌採取用具が破損して破片が飛び散ってしまった場合でも金属探知機等を用いて容易に回収することができる点から、金属材料が用いられる。例えば、鉄、ニッケル、チタン、真鍮、ステンレス、アルミニウムあるいはこれらの合金などが挙げられる。中でも、耐久性、防錆性の面からステンレスが好ましい。   The material of the grip portion 10 and the movable portion 11 has the strength to withstand the expansion and contraction operation and the abrasion operation, and even if the bacteria collection tool is damaged and fragments are scattered, it is easy to use a metal detector or the like. A metal material is used because it can be recovered. Examples thereof include iron, nickel, titanium, brass, stainless steel, aluminum and alloys thereof. Of these, stainless steel is preferable from the viewpoint of durability and rust resistance.

固定具12は、可動部11eの、可動部11dとは反対側の端部に配置されている。固定具12としては、例えば、メカニカルファスナー(面ファスナーとも称される。)、ゴムバンド、ゴムシート、樹脂フィルム、樹脂シート、樹脂テープなどを用いることができる。中でも、取付け容易性、綿棒交換容易性、コストの面からメカニカルファスナー、ゴムバンドが好ましい。   The fixture 12 is arranged at the end of the movable portion 11e opposite to the movable portion 11d. As the fixture 12, for example, a mechanical fastener (also referred to as a surface fastener), a rubber band, a rubber sheet, a resin film, a resin sheet, a resin tape, or the like can be used. Of these, mechanical fasteners and rubber bands are preferable in terms of easy installation, easy swab replacement, and cost.

固定具12がメカニカルファスナーの場合には、帯状のメカニカルファスナーの表面にフック材が形成され、裏面にループ材が形成されたものを好適に用いることができる。フック材とループ材それぞれが形成された2本のメカニカルファスナーを、接着剤等で貼りあわせたものでもよい。帯状メカニカルファスナーの短辺を可動部に当接させ、メカニカルファスナーのフック材とループ材とが重なるように巻き取ることで、可動部に固定することができる。メカニカルファスナーの幅(短辺の長さ)は綿棒を固定できる幅であれば特に限定されない。綿棒は、可動部先端部に固定したメカニカルファスナーの一部分を剥がし取り、剥がし取ったところに綿棒の軸部を挿入して再び固定することにより取り付ける。   When the fixture 12 is a mechanical fastener, a belt-shaped mechanical fastener having a hook material formed on the surface and a loop material formed on the back surface can be preferably used. Two mechanical fasteners each having a hook material and a loop material may be bonded together with an adhesive or the like. The short side of the strip-shaped mechanical fastener is brought into contact with the movable portion, and the hook material and the loop material of the mechanical fastener are wound so as to overlap with each other, whereby the mechanical fastener can be fixed to the movable portion. The width of the mechanical fastener (the length of the short side) is not particularly limited as long as it can fix the swab. The cotton swab is attached by peeling off a part of the mechanical fastener fixed to the tip of the movable portion, inserting the shaft portion of the cotton swab into the peeled off portion, and fixing again.

メカニカルファスナーとは、凸部材であるフック材と、凹部材であるループ材とからなり、フック材をループ材内に挿入することで機械的に結合し固定できるものである。フック材としては、例えば、表面に多数の突起(鉤状、きのこ状、錨状等)が形成されたものが用いられる。   The mechanical fastener is composed of a hook member that is a convex member and a loop member that is a recessed member, and can be mechanically coupled and fixed by inserting the hook member into the loop member. As the hook material, for example, one having a large number of protrusions (hook-shaped, mushroom-shaped, anchor-shaped, etc.) formed on its surface is used.

メカニカルファスナーとしては、ポリエステル、ポリアミド、ポリプロピレン、ポリエチレンなどの合成繊維あるいは天然繊維、又はこれらの組み合わせで作製されたものを使用できる。   As the mechanical fastener, synthetic fibers made of polyester, polyamide, polypropylene, polyethylene, or natural fibers, or those made of a combination thereof can be used.

固定具12がゴムバンドの場合には、天然ゴム又は合成ゴムからなるゴムバンドなどを使用できる。固定時には、可動部先端部に綿棒の軸部を当接させ、巻き付けるようにして取り付ける。   When the fixture 12 is a rubber band, a rubber band made of natural rubber or synthetic rubber can be used. At the time of fixing, the shaft part of the cotton swab is brought into contact with the tip part of the movable part, and it is attached by winding.

固定具12がゴムシート、樹脂フィルム、樹脂シート、樹脂テープ(以下、まとめてゴムシート等と称することがある。)の場合には、拭取検査の擦過でも磨耗しにくく、固定具に付着物が付着してもエタノールなどで容易に除去できるようにするため、耐摩耗性、耐薬品性を有していることが好ましい。固定時には、可動部先端部に綿棒の軸部を当接させ、ゴムシート等を巻き付けて固定する。固定方法は、ゴムシート等の一方の面に接着剤が塗布されているものを使用してもよいし、巻き付け時に別途接着剤を塗布してもよい。ゴムシート等の幅(短辺の長さ)は、綿棒を固定できる幅であれば特に限定されない。   When the fixing tool 12 is a rubber sheet, a resin film, a resin sheet, or a resin tape (hereinafter, may be collectively referred to as a rubber sheet, etc.), the fixing tool 12 does not easily wear even after rubbing in a wiping test, and adheres to the fixing tool. It is preferable to have abrasion resistance and chemical resistance so that even if adhered, it can be easily removed with ethanol or the like. At the time of fixing, the shaft part of the swab is brought into contact with the tip of the movable part, and a rubber sheet or the like is wound around and fixed. As a fixing method, one having an adhesive applied to one surface of a rubber sheet or the like may be used, or an adhesive may be applied separately at the time of winding. The width (length of the short side) of the rubber sheet or the like is not particularly limited as long as it is a width that can fix the swab.

ゴムシートを構成するゴムとしては、天然ゴム、合成ゴムが挙げられる。
樹脂フィルム、樹脂シート、樹脂テープを構成する樹脂としては、ポリ塩化ビニル、塩化ビニリデン樹脂、ポリエチレン、ポリプロピレン、ポリアミド、フッ素樹脂などが挙げられる。
Examples of the rubber that constitutes the rubber sheet include natural rubber and synthetic rubber.
Examples of the resin that constitutes the resin film, the resin sheet, and the resin tape include polyvinyl chloride, vinylidene chloride resin, polyethylene, polypropylene, polyamide, and fluororesin.

また、クリーンルームなどの高い清潔性が求められる場合には、上述したメカニカルファスナーにゴムシート、樹脂フィルム、樹脂シートあるいは樹脂テープなどを巻き付けて被覆することが好ましい。中でも、耐久性、耐摩耗性、耐薬品性、取付け容易性に優れ、固定具からの発塵を確実に防止できる点から、メカニカルファスナーにゴムシートを被覆したものが好ましい。これにより、切断用カッターや機械の突起部などに引っ掛かってもメカニカルファスナーから糸くずが脱落することがなく、また菌採取時に汚れが付着しても汚れを容易に除去できるため、二次汚染を防止することができる。固定時には、メカニカルファスナーの短辺を可動部に当接させて巻き付けたのち、ゴムシート等を巻き付けて固定する。固定方法は、上述したゴムシート等の固定方法と同じでよい。ゴムシート等の幅(短辺の長さ)は、メカニカルファスナーと同じかあるいは若干長い程度でよい。綿棒は、メカニカルファスナーのフック材とループ材の隙間に差し込むことにより取り付ける。これにより、適度な摩擦で拭取検査時も抜けづらく、また綿棒を引っ張ると容易に抜けるため交換も容易となる。   Further, when high cleanliness such as in a clean room is required, it is preferable that the mechanical fastener described above be wrapped with a rubber sheet, a resin film, a resin sheet, a resin tape, or the like for coating. Of these, mechanical fasteners coated with a rubber sheet are preferable because they have excellent durability, abrasion resistance, chemical resistance, and ease of attachment and can reliably prevent dust from being generated from the fixture. As a result, the lint will not fall off from the mechanical fasteners even if it gets caught by the cutting cutter or the protrusion of the machine, and the stains can be easily removed even if stains are attached at the time of collecting bacteria. Can be prevented. At the time of fixing, the short side of the mechanical fastener is brought into contact with the movable part and wound, and then a rubber sheet or the like is wound and fixed. The fixing method may be the same as the above-mentioned fixing method for the rubber sheet or the like. The width (length of the short side) of the rubber sheet or the like may be the same as or slightly longer than that of the mechanical fastener. Attach the cotton swab by inserting it into the gap between the hook and loop members of the mechanical fastener. As a result, it is difficult to remove it even during a wiping test due to moderate friction, and it can be easily removed by pulling the cotton swab, so replacement is easy.

固定具12は、JIS B9923 クリーンルーム用衣服の汚染粒子測定方法に記載のタンブリング法により発塵させ、パーティクルカウンターで測定したときの塵の粒径0.5μm以上の発塵個数が3,520個/m以下であることが好ましい。これにより、菌採取用具から塵埃を発塵させる心配がなく、採取した付着物以外の菌や塵埃が付着することがない。 The fixture 12 is made to generate dust by the tumbling method described in JIS B9923 Clean Room Clothes Particle Measurement Method, and the number of dust particles having a particle size of 0.5 μm or more measured with a particle counter is 3,520 / It is preferably m 3 or less. As a result, there is no concern that dust will be generated from the bacteria collecting tool, and bacteria and dust other than the collected adhered substances will not adhere.

粒径0.5μm以上の発塵個数が3,520個/m以下とは、JIS B9920:2002(ISO 14644−1) クリーンルームの空気清浄度の評価方法、4.清浄度クラスの「クラス5」、又は、アメリカ連邦規格Fed.Std.209Dの「クラス100」に相当する。 3. The number of dust particles having a particle size of 0.5 μm or more is 3,520 particles / m 3 or less means that JIS B9920: 2002 (ISO 14644-1) is an evaluation method of air cleanliness in a clean room. Cleanliness class "Class 5" or US Federal Standard Fed. Std. This is equivalent to "Class 100" of 209D.

And a metallic linear body 14 fixed to the tip of the movable portion via a fixing tool 12, and a sterile cotton swab 13 fixed to the tip of the linear body 14 via a fixing tool 15. It
The gripping portion, the movable portion, the fixing tool 12, and the sterile cotton swab 13 are the same as those described in the first embodiment.

線状体14は、屈曲又は湾曲可能で、かつ屈曲又は湾曲させた形状を保持できる強度と耐久性を有するものを使用することができる。万が一破損してしまった場合でも金属探知機等で探すことができる点より、金属製の線状体、例えば針金などが好ましい。針金は人間の手で比較的簡単に曲げることができるため好ましい。材料としては、例えば、鉄、スチール、銅、真鍮、ステンレス、アルミニウムあるいはこれらの合金などが挙げられる。線状体14の長さは、菌を採取する場所に応じ適宜な長さのものを使用することができる。   The linear body 14 may be bendable or bendable, and may have strength and durability capable of holding the bent or curved shape. A metal linear body, for example, a wire is preferable because it can be searched by a metal detector or the like even if it is damaged. Wires are preferred because they can be bent relatively easily by human hands. Examples of the material include iron, steel, copper, brass, stainless steel, aluminum, and alloys thereof. The length of the linear body 14 may be an appropriate length depending on the place where the bacteria are collected.

固定具15は、上述した固定具12と同じものを使用でき、中でもゴムバンドを好適に使用できる。固定具15がゴムバンドであれば、線状体14に滅菌綿棒13を固定したときの厚み(直径)が大きくならずに固定できるので、メカニカルファスナーでは上手く挿入することが難しい細い箇所や狭い箇所でも容易に挿入でき、菌採取のために空調機器や製造機械を停止させたり、パーツを一部取り外して菌採取用の開口部を設けたりする必要がない。   As the fixture 15, the same one as the fixture 12 described above can be used, and among them, a rubber band can be preferably used. If the fixture 15 is a rubber band, the sterilized cotton swab 13 can be fixed to the linear body 14 without increasing the thickness (diameter) of the sterilized cotton swab 13, so that it is difficult to insert the mechanical fastener properly into a narrow or narrow place. However, it can be easily inserted, and it is not necessary to stop the air conditioner or the manufacturing machine to collect bacteria, or to remove some parts to provide an opening for collecting bacteria.
