本発明は、空気中に浮遊する細菌、真菌等の微生物（以下、「空中浮遊菌」という。）を捕集し、培養したり、ＡＴＰ計測により菌の量を計数することにより、バイオクリーンルームや無菌食品、無菌充填飲料等の製造設備等の環境を測定するために用いられる空中浮遊菌捕集機の捕集具の装着部構造に関し、特に、捕集具の装着部に汎用性を持たせるようにした空中浮遊菌捕集機の捕集具の装着部構造及び該捕集具の装着部構造を備えた空中浮遊菌捕集機に関するものである。   The present invention collects and cultures microorganisms such as bacteria and fungi floating in the air (hereinafter referred to as “airborne bacteria”), cultures, and counts the amount of bacteria by ATP measurement, Concerning the structure of the mounting part of the airborne microbe collector used to measure the environment of manufacturing equipment such as aseptic food and aseptically filled beverages, in particular, make the mounting part of the collecting tool versatile It is related with the mounting part structure of the collector of the airborne microbe collector made like this, and the airborne microbe collector provided with the mounting part structure of this collector.

従来、バイオクリーンルームや無菌製剤、無菌食品、無菌充填飲料等の製造設備等の環境を測定するために、空中浮遊菌を捕集し、培養したり、ＡＴＰ計測により菌の量を計数することが行われており、このために、空中浮遊菌捕集機が用いられている（例えば、特許文献１参照）。   Conventionally, in order to measure the environment of manufacturing facilities such as bioclean rooms, aseptic preparations, aseptic foods, and aseptic filled beverages, airborne bacteria can be collected and cultured, or the amount of bacteria can be counted by ATP measurement. For this purpose, an airborne bacteria collector is used (for example, see Patent Document 1).

特開２０００−３００２４６号公報Japanese Patent Laid-Open No. 2000-3000246

ところで、空中浮遊菌の計測のために、ゼラチンを含む専用の担体に空中浮遊菌を固定し、ゲル状の担体を溶解してゾル化し、ＡＴＰ計測を行うためには、作業性等の点から、専用の担体容器が使用されている。   By the way, in order to measure airborne bacteria, it is necessary to fix the airborne bacteria on a dedicated carrier containing gelatin, dissolve the gel-like carrier into a sol, and perform ATP measurement from the viewpoint of workability, etc. A dedicated carrier container is used.

一方、例えば、無菌製剤の製造設備の環境測定方法として、寒天培地を使用した平板培養法が、公定法（「医薬品及び医薬部外品の製造管理及び品質管理の基準に関する省令」の求める基準、いわゆる、「ＧＭＰ」に適合する方法。）として一般的に使用されている。
この平板培養法では、寒天培地（担体）の容器として、直径９０ｍｍのガラス製シャーレや使い捨て可能なプラスチック製シャーレが使用されている。
このように、公定法に適用される空中浮遊菌捕集機は、直径９０ｍｍのシャーレが使用できることが必要条件となっている。 On the other hand, for example, as an environmental measurement method for manufacturing equipment for sterile preparations, a plate culture method using an agar medium is an official method (standards required by the Ministerial Ordinance on Standards for Manufacturing Control and Quality Control of Pharmaceuticals and Quasi-drugs, It is generally used as a so-called “GMP” method.
In this plate culture method, a glass petri dish having a diameter of 90 mm or a disposable plastic petri dish is used as a container for an agar medium (carrier).
Thus, it is a necessary condition that an airborne bacteria trap applied to the official method can use a petri dish having a diameter of 90 mm.

このように、ＡＴＰ計測に適用される空中浮遊菌捕集機と、公定法に適用される空中浮遊菌捕集機とは、捕集具として、専用の担体容器と直径９０ｍｍのシャーレという形状の異なる捕集具を用いるため、当然、捕集具の装着部の構造が異なり、ＡＴＰ計測と公定法の両方の方法を実施する必要のある、例えば、無菌製剤の製造設備の管理者は、それぞれに適合する空中浮遊菌捕集機を保有する必要があった。   Thus, the airborne microbe collector applied to ATP measurement and the airborne microbe collector applied to the official method have a dedicated carrier container and a petri dish with a diameter of 90 mm as a collector. Since different collectors are used, of course, the structure of the mounting part of the collector is different, and it is necessary to carry out both the ATP measurement and the official method. It was necessary to have an airborne bacteria trap that conforms to

本発明は、形状の異なる捕集具に対応することができる空中浮遊菌捕集機の捕集具の装着部構造及び該捕集具の装着部構造を備えた空中浮遊菌捕集機を提供することを目的とする。   The present invention provides a mounting part structure of a trap for an airborne microbe collector that can correspond to a collector having a different shape, and an airborne microbe collector provided with the mounting part structure of the collector The purpose is to do.

上記目的を達成するため、本発明の空中浮遊菌捕集機の捕集具の装着部構造は、担体を収容した捕集具を装着し、前記担体の表面に、吸引ヘッドに形成したノズル孔から吸引される空気に含まれる空中浮遊菌を付着させるようにした空中浮遊菌捕集機の捕集具の装着部構造において、第１の捕集具に係止爪を形成し、該係止爪を台座に形成した切欠部を通して溝に差し込み、該第１の捕集具を回転させることによって、台座に形成した第１の凹部に嵌め込んで装着可能とするとともに、前記第１の捕集具よりも平面形状の大きい第２の捕集具を、前記台座の第１の凹部の上方に形成した第２の凹部に嵌め込んで装着可能とするようにしたことを特徴とする。   In order to achieve the above object, the mounting part structure of the trapping device of the airborne microbe collector of the present invention has a nozzle hole formed in the suction head on the surface of the carrier, which is equipped with a collector containing the carrier. In the mounting part structure of the collection device of the airborne bacteria trapping device to which airborne bacteria contained in the air sucked from the air is attached, a locking claw is formed on the first collection device, The claw is inserted into the groove through the notch formed in the pedestal, and the first collection tool is rotated to be fitted into the first recess formed in the pedestal, and the first collection. The second collection tool having a larger planar shape than the tool is fitted into a second recess formed above the first recess of the pedestal so as to be mounted.

この場合において、吸引ヘッドに形成したノズル孔から吸引される空気に含まれる空中浮遊菌を慣性法により付着させるようにすることができる。   In this case, airborne bacteria contained in the air sucked from the nozzle holes formed in the suction head can be attached by the inertia method.

また、第１の捕集具及び第２の捕集具に適合したノズル孔が形成された第１の吸引ヘッド及び第２の吸引ヘッドを選択して用いるようにすることができる。   Moreover, the 1st suction head and the 2nd suction head in which the nozzle hole suitable for the 1st collection tool and the 2nd collection tool was formed can be selected and used.

また、上記の捕集具の装着部構造を備えた本発明の空中浮遊菌捕集機は、空中浮遊菌捕集機の重心位置に揺動自在に取っ手を配設するとともに、該取っ手を持って空中浮遊菌捕集機を吊り下げた状態にしたとき、取っ手が空中浮遊菌捕集機の本体に固定されるようにしてなることを特徴とする。   In addition, the airborne microbe collector of the present invention having the above-described mounting part structure of the collector is provided with a handle swingably at the center of gravity of the airborne microbe collector and has the handle. When the airborne bacteria collector is suspended, the handle is fixed to the body of the airborne bacteria collector.

本発明の空中浮遊菌捕集機の捕集具の装着部構造によれば、１台の空中浮遊菌捕集機でもって形状の異なる捕集具に対応することができることから、例えば、ＡＴＰ計測と公定法の両方の方法を実施する場合に、１台の空中浮遊菌捕集機を共用することができる。   According to the mounting part structure of the airborne microbe collector of the present invention, it is possible to cope with different types of collectors with a single airborne microbe collector. When implementing both the official method and the official method, a single airborne microbe collector can be shared.

また、第１の捕集具及び第２の捕集具に適合したノズル孔が形成された第１の吸引ヘッド及び第２の吸引ヘッドを選択して用いるようにすることにより、適切な条件で、例えば、ＡＴＰ計測と公定法の両方の方法を実施することができる。   In addition, by selecting and using the first suction head and the second suction head in which the nozzle holes suitable for the first collection tool and the second collection tool are formed, under appropriate conditions For example, both ATP measurement and official methods can be implemented.

また、本発明の空中浮遊菌捕集機によれば、台座に捕集具を装着した状態で空中浮遊菌捕集機を安定して持ち運ぶことができ、作業性を向上することができる。   Moreover, according to the airborne microbe collector of the present invention, the airborne microbe collector can be stably carried with the collector mounted on the pedestal, and workability can be improved.

図１に、本発明の空中浮遊菌捕集機の捕集具の装着部構造を適用した空中浮遊菌捕集機の一実施例を示す。   In FIG. 1, one Example of the airborne microbe collector which applied the mounting part structure of the collector of the airborne microbe collector of this invention is shown.

この空中浮遊菌捕集機１は、担体を収容した捕集具２Ａ、２Ｂを装着する台座３を備え、台座３に装着した捕集具２Ａ、２Ｂに収容した担体２１、２４の表面に、吸引ヘッド４Ａ、４Ｂに形成したノズル孔４１Ａ、４１Ｂから吸引される空気に含まれる空中浮遊菌を慣性法により衝突、付着させるようにしたものである。   This airborne microbe collector 1 includes a pedestal 3 on which collectors 2A and 2B containing carriers are mounted, and on the surfaces of the carriers 21 and 24 stored in the collectors 2A and 2B mounted on the pedestal 3, Airborne bacteria contained in the air sucked from the nozzle holes 41A and 41B formed in the suction heads 4A and 4B are made to collide and adhere by the inertia method.

そして、この空中浮遊菌捕集機１は、具体的には、密閉構造とした筒状の胴部１０の上部に、ノズル孔４１Ａ、４１Ｂを形成した吸引ヘッド４Ａ、４Ｂを、その内部に台座３及び台座３に装着される捕集具２Ａ、２Ｂを収容できる空間を形成するようにして、着脱可能に配設するようにしている。   And this airborne microbe collector 1 specifically, the suction heads 4A and 4B in which the nozzle holes 41A and 41B are formed in the upper part of the cylindrical barrel part 10 having a sealed structure are mounted on the inside thereof. 3 and the pedestal 3 are disposed so as to be detachable so as to form a space in which the collecting tools 2A and 2B mounted on the pedestal 3 can be accommodated.

台座３の下方には、通気路５を介して、吸引ヘッド４Ａ、４Ｂの内部を負圧にすることによって、吸引ヘッド４Ａ、４Ｂに形成したノズル孔４１Ａ、４１Ｂから空気を吸引し、この空気に含まれる空中浮遊菌を慣性法により、台座３に装着した捕集具２Ａ、２Ｂに収容した担体２１、２４の表面に、衝突、付着させるようにするためのターボファン６を配設し、さらに、ターボファン６に吸引された、空中浮遊菌が担体２１、２４の表面に衝突、付着することにより除去された空気を、ターボファン６から排出され、ターボファン６内で発生した発塵粒子等をフィルタ７を通して除去した後に、大気に放出するようにしている。   Below the pedestal 3, air is sucked from the nozzle holes 41 </ b> A and 41 </ b> B formed in the suction heads 4 </ b> A and 4 </ b> B by setting the inside of the suction heads 4 </ b> A and 4 </ b> B to a negative pressure via the air passage 5. A turbofan 6 for causing the airborne bacteria contained in the carrier to collide and adhere to the surfaces of the carriers 21 and 24 accommodated in the collectors 2A and 2B attached to the pedestal 3 by the inertia method, Further, air removed by the airborne bacteria sucked into the turbofan 6 colliding with and adhering to the surfaces of the carriers 21 and 24 is discharged from the turbofan 6 and generated dust particles generated in the turbofan 6. Etc. are removed through the filter 7 and then released into the atmosphere.

また、この空中浮遊菌捕集機１は、商用電源のない場所でも使用することができるように、充電池等のバッテリ８を着脱可能に備えるようにしている。   Moreover, this airborne microbe collector 1 is provided with a battery 8 such as a rechargeable battery so that it can be used even in a place without a commercial power source.

また、この空中浮遊菌捕集機１の持ち運びは、空中浮遊菌捕集機１の本体の重心位置に揺動自在に取っ手９を配設するとともに、この取っ手９を持って空中浮遊菌捕集機１を吊り下げた状態にしたとき、取っ手が空中浮遊菌捕集機１の本体に固定されるようにしている。
具体的には、図３（ａ）（取付ねじを省略）に示すように、取っ手９を持って空中浮遊菌捕集機１を吊り下げるために取っ手９を引き上げると、取っ手９を軸支する対向する平面を備えた軸部９２が、取っ手９に形成した軸孔９１の対向する平面を備えた狭小部に嵌入し、取っ手９を持って空中浮遊菌捕集機１を吊り下げた状態では、取っ手９が空中浮遊菌捕集機１の本体に固定され、取っ手９に対する空中浮遊菌捕集機１の本体の揺動が防止できるようにしている。
一方、空中浮遊菌捕集機１を載置し、取っ手９をおろした状態では、図３（ｂ）（取付ねじを省略）に示すように、取っ手９を軸支する軸部９２が、取っ手９に形成した軸孔９１の大径部に位置し、取っ手９は空中浮遊菌捕集機１の本体に対して揺動可能となるようにされ、空中浮遊菌捕集機１による空中浮遊菌の捕集時に、取っ手９が邪魔にならないようにしている。 The airborne bacteria collector 1 can be carried by arranging a handle 9 at the center of gravity of the body of the airborne bacteria collector 1 so as to be swingable, and holding the handle 9 to collect the airborne bacteria. When the machine 1 is in a suspended state, the handle is fixed to the body of the airborne microbe collector 1.
Specifically, as shown in FIG. 3A (the mounting screw is omitted), when the handle 9 is lifted to hold the airborne bacteria trap 1 with the handle 9, the handle 9 is pivotally supported. In a state where the shaft portion 92 provided with the opposed plane is fitted into the narrow portion provided with the opposed plane of the shaft hole 91 formed in the handle 9 and the airborne bacteria trap 1 is suspended with the handle 9 The handle 9 is fixed to the main body of the airborne microbe collector 1 so that the main body of the airborne microbe collector 1 can be prevented from swinging with respect to the handle 9.
On the other hand, when the airborne bacteria trap 1 is placed and the handle 9 is lowered, as shown in FIG. 3B (the mounting screw is omitted), the shaft portion 92 that pivotally supports the handle 9 has a handle. The handle 9 is positioned at the large diameter portion of the shaft hole 91 formed in 9, so that the handle 9 can swing with respect to the main body of the airborne microbe collector 1. The handle 9 is kept out of the way during the collection.

この場合において、台座３に、形状の異なる捕集具２Ａ、２Ｂ、具体的には、ＡＴＰ計測用の専用の担体容器からなる捕集具２Ａと、直径９０ｍｍのシャーレからなる捕集具２Ｂとを選択的に装着することができるようにしている。   In this case, on the pedestal 3, the collectors 2A and 2B having different shapes, specifically, a collector 2A composed of a dedicated carrier container for ATP measurement, and a collector 2B composed of a petri dish having a diameter of 90 mm Can be worn selectively.

具体的には、平面形状の小さいＡＴＰ計測用の専用の担体容器からなる捕集具２Ａは、ゼラチンを含む専用の担体２１を収容した捕集皿２２を上部に備えるようにし、下部に１個又は複数個（本実施例においては、１２０°の間隔をあけて３個）の係止爪２３を形成した構造とし、係止爪２３を台座３に形成した切欠部３１ａを通して溝３１に差し込み、捕集具２Ａを回転させることによって、台座３に形成した第１の凹部３２に嵌め込んで装着する構造（バヨネットマウント構造）を採用している。
この場合、溝３１には、捕集具２Ａを所定角度、例えば、３０°回転させたときに係止爪２３が当接する停止突起（図示省略）を設けることができる。
上記構造の捕集具２Ａは、捕集皿２２に直接に手を触れずに、台座３に装着することができ、ＡＴＰ計測のノイズを低減できるようにしている。
なお、捕集具２Ａに取り付ける捕集皿２２は、任意の形状のものを選択可能である。 Specifically, the collecting tool 2A comprising a dedicated carrier container for ATP measurement with a small planar shape is provided with a collecting tray 22 containing a dedicated carrier 21 containing gelatin in the upper part, and one in the lower part. Or it is set as the structure which formed the latching claw 23 of a plurality (three in this embodiment, with a 120 degree space | interval), and the latching claw 23 is inserted in the groove | channel 31 through the notch part 31a formed in the base 3, A structure (bayonet mount structure) that is fitted into the first recess 32 formed in the base 3 by rotating the collecting tool 2A (a bayonet mount structure) is employed.
In this case, the groove 31 can be provided with a stop protrusion (not shown) on which the locking claw 23 comes into contact when the collecting tool 2A is rotated by a predetermined angle, for example, 30 °.
The collecting tool 2A having the above-described structure can be mounted on the base 3 without directly touching the collecting plate 22 so that noise in ATP measurement can be reduced.
In addition, the thing of arbitrary shapes can be selected for the collection tray 22 attached to 2 A of collection tools.

このＡＴＰ計測用の専用の担体容器からなる捕集具２Ａを装着する場合には、この捕集具２Ａに合わせたノズル孔４１Ａが形成された吸引ヘッド４Ａ、具体的には、２００個程度の多数のノズル孔４１Ａが形成された吸引ヘッド４Ａを用いるようにし、ノズル孔４１Ａと担体２１との間隔が空中浮遊菌が衝突して捕集できる距離、例えば、数ｍｍ程度、本実施例においては、１．６ｍｍの距離となるように設定するようにする。
なお、ノズル孔４１Ａと担体２１との間隔の調整は、空中浮遊菌捕集機１の構成部材の調節や捕集具２Ａの選択により、さらに、微調整は、担体２１の充填量を調節することにより行うことができる。 In the case where the collecting tool 2A composed of a dedicated carrier container for ATP measurement is mounted, the suction head 4A in which the nozzle hole 41A corresponding to the collecting tool 2A is formed, specifically about 200 pieces. The suction head 4A in which a large number of nozzle holes 41A are formed is used, and the distance between the nozzle holes 41A and the carrier 21 is a distance at which airborne bacteria can collide and collect, for example, about several mm. The distance is set to 1.6 mm.
In addition, adjustment of the space | interval of the nozzle hole 41A and the support | carrier 21 adjusts the filling amount of the support | carrier 21 further by fine adjustment by adjustment of the structural member of the airborne microbe collector 1 and selection of the collection tool 2A. Can be done.

一方、ＡＴＰ計測用の専用の担体容器からなる捕集具２Ａよりも平面形状の大きい９０ｍｍシャーレは、寒天培地からなる担体２４を収容するようにし、台座３に形成した第１の凹部３２の上方に同心状に形成した第２の凹部３３に嵌め込んで装着する構造を採用している。
この場合、台座３に形成する凹部３３は、若干大きさに違いのある汎用の９０ｍｍシャーレのすべてに対応することができるように、９０ｍｍシャーレの平面形状よりも若干大きく形成するようにする。
また、必要に応じて、凹部３３を区画する立ち上がり縁３４に、９０ｍｍシャーレの外周表面に当接して、付勢する押さえバネからなる押圧係止部材３５を複数個（本実施例においては、１２０°の間隔をあけて３個）配設するようにすることができる。 On the other hand, the 90 mm petri dish having a planar shape larger than the collecting tool 2A made up of a dedicated carrier container for ATP measurement accommodates the carrier 24 made up of an agar medium, above the first recess 32 formed in the pedestal 3. A structure is employed in which the second recess 33 is concentrically fitted to and attached to the second recess 33.
In this case, the concave portion 33 formed in the base 3 is formed to be slightly larger than the planar shape of the 90 mm petri dish so that it can correspond to all general purpose 90 mm petri dishes having slightly different sizes.
Further, if necessary, a plurality of pressing locking members 35 (pressing members 120 in this embodiment) made of pressing springs that abut against the outer peripheral surface of the 90 mm petri dish and urge the rising edge 34 that divides the concave portion 33. 3) can be arranged with an interval of °.

この９０ｍｍシャーレからなる捕集具２Ｂを装着する場合には、この捕集具２Ｂに合わせたノズル孔４１Ｂが形成された吸引ヘッド４Ｂを用いるようにし、ノズル孔４１Ｂと担体２４との間隔が空中浮遊菌が衝突して捕集できる距離、例えば、数ｍｍ程度、本実施例においては、１．６ｍｍの距離となるように設定するようにする。
なお、ノズル孔４１Ｂと担体２４との間隔の調整は、空中浮遊菌捕集機１の構成部材の調節により、さらに、微調整は、担体２４の充填量を調節することにより行うことができる。 When the collection tool 2B made of this 90 mm petri dish is mounted, the suction head 4B in which the nozzle hole 41B is formed in accordance with the collection tool 2B is used, and the gap between the nozzle hole 41B and the carrier 24 is in the air. The distance at which airborne bacteria collide and can be collected, for example, about several mm, in this embodiment, the distance is set to 1.6 mm.
The adjustment of the distance between the nozzle hole 41B and the carrier 24 can be performed by adjusting the constituent members of the airborne microbe collector 1, and the fine adjustment can be performed by adjusting the filling amount of the carrier 24.

この空中浮遊菌捕集機１は、台座３に、ＡＴＰ計測用の専用の担体容器からなる捕集具２Ａと、直径９０ｍｍのシャーレからなる捕集具２Ｂとを選択的に装着することができるようにし、さらに、それぞれの捕集具２Ａ、２Ｂに適合したノズル孔４１Ａ、４１Ｂが形成された吸引ヘッド４Ａ、４Ｂを用いるようにしているので、１台の空中浮遊菌捕集機１をＡＴＰ計測と公定法とに共用することができる。   This airborne microbe collector 1 can selectively mount on a pedestal 3 a collector 2A made of a carrier container dedicated for ATP measurement and a collector 2B made of a petri dish having a diameter of 90 mm. In addition, since the suction heads 4A and 4B in which the nozzle holes 41A and 41B suitable for the respective collectors 2A and 2B are formed are used, one airborne microbe collector 1 is connected to the ATP. It can be used for both measurement and official methods.

なお、この空中浮遊菌捕集機１に用いる吸引ヘッド４Ａ、４Ｂは、例えば、金属製でオートクレーブ滅菌を行うことによって再使用できるものとしたり、合成樹脂製でワンウェイ（使い捨て）のものとすることができる。   The suction heads 4A and 4B used in the airborne microbe collector 1 are made of metal and can be reused by autoclaving, or made of synthetic resin and one-way (disposable). Can do.

また、この空中浮遊菌捕集機１は、持ち運びを、空中浮遊菌捕集機１の本体の重心位置に揺動自在に取っ手９を配設するとともに、この取っ手９を持って空中浮遊菌捕集機１を吊り下げた状態にしたとき、取っ手が空中浮遊菌捕集機１の本体に固定されるようにしているが、これにより、台座３に捕集具２Ａ、２Ｂを装着した状態で空中浮遊菌捕集機１を安定して持ち運ぶことができ、作業性を向上することができる。   In addition, the airborne microbe collector 1 is provided with a handle 9 swingably at the center of gravity of the main body of the airborne microbe collector 1. When the collector 1 is in a suspended state, the handle is fixed to the main body of the airborne bacteria collector 1, but this allows the pedestal 3 to be equipped with the collectors 2A and 2B. The airborne bacteria collector 1 can be carried stably and workability can be improved.
