Description

本発明は、外部雰囲気から離隔された空間を形成し、この空間内部で処理対象物の処理作業を行う際に、有害成分により処理対象物が汚染されたり、処理対象物から生じる有害成分が外部に流出することを防止する隔離作業装置および隔離作業装置の作業方法に関するものである。   The present invention forms a space separated from the external atmosphere, and when the processing object is processed inside this space, the processing object is contaminated by harmful components, or harmful components generated from the processing object are external. It is related with the isolation | separation work apparatus which prevents that it leaks out to a head, and the working method of an isolation | separation work apparatus.

内部を陽圧にして無菌状態を維持するアイソレータ、クリーンベンチ、クリーンルーム等の外部雰囲気から隔離された空間を形成する隔離作業装置では、内部を無菌化するために過酸化水素蒸気、エチレンオキサイドガス、ホルムアルデヒドガス等の除染ガスで除染を行った後、除染ガスを除去するためにエアレーションを行う。ところが、エアレーションを行っても、作業用グローブやハーフスーツ、シール部等の構造体に用いている樹脂材料には除染ガス成分が内部に浸透してしまうので、十分に取り除くことができない。取り除くことができなかった除染ガス成分は、時間の経過とともに隔離作業装置の空間内部に再放出されてしまう。この空間内部で処理される物が、細胞や薬品等の除染ガス成分に敏感な物質の場合には、再放出された除染ガスの影響が懸念される。   In an isolation device that forms a space isolated from the external atmosphere such as an isolator, clean bench, clean room, etc. that maintains the sterility by positive pressure inside, in order to sterilize the interior, hydrogen peroxide vapor, ethylene oxide gas, After decontamination with a decontamination gas such as formaldehyde gas, aeration is performed to remove the decontamination gas. However, even if aeration is performed, the decontamination gas component penetrates into the resin material used in the structure such as the work gloves, the half suit, and the seal portion, and thus cannot be sufficiently removed. The decontamination gas component that could not be removed is re-released into the space of the isolation work device over time. If the object to be treated in this space is a substance sensitive to decontamination gas components such as cells and chemicals, there is a concern about the influence of the decontamination gas re-released.

また、内部を陰圧にして有害物質の流出を防止するようにしたハザードアイソレータや安全キャビネット等の隔離作業装置では、有害物質の漏出に細心の注意を払う必要がある。例えば、作業用グローブやハーフスーツにピンホールが生じた場合には、隔離作業装置の空間内部を陰圧に維持しているため、雰囲気として漏出する可能性は低いが、作業者が直接触れる危険性は免れない。   In addition, it is necessary to pay close attention to the leakage of harmful substances in hazard isolators and safety cabinets and the like that prevent negative substances from flowing out by using negative pressure inside. For example, if a pinhole occurs in a work glove or half suit, the space inside the isolation work device is maintained at a negative pressure, so there is little possibility of leakage as an atmosphere, but there is a danger of direct contact with the worker. Sex is inevitable.

図３は、前記作業室４内で使用するシート状部材２４である。この実施例では、シート状部材２４は袋状に形成されており、下方側は開放している。この袋状をしたシート状部材２４の下部２４ａ寄りに、シート状部材２４の内部で作業をするための手袋２６が、カラー２９を介して取り付けられている。シート状部材２４は、過酸化水素蒸気、エチレンオキサイドガス、ホルムアルデヒドガス等の有害成分を含む除染ガスを吸着する性質を有する素材からできている。具体的には、ナイロンや活性炭を原材料とした繊維、不織布、フィルム、シートからなる材料を用いている。この実施例では、これらシート状部材２４を袋状に加工している。また、シート状部材２４に設けられている手袋２６も、シート状部材２４と同一の材質で形成されている。前記原材料のうちナイロンは、特に、過酸化水素成分の吸着に有効であり、また安価であり、しかも、袋状に加工しやすいという優れた性質を有している。   FIG. 3 shows a sheet-like member 24 used in the work chamber 4. In this embodiment, the sheet-like member 24 is formed in a bag shape, and the lower side is open. Gloves 26 for working inside the sheet-like member 24 are attached via collars 29 near the lower portion 24 a of the bag-like sheet-like member 24. The sheet-like member 24 is made of a material having a property of adsorbing a decontamination gas containing harmful components such as hydrogen peroxide vapor, ethylene oxide gas, and formaldehyde gas. Specifically, materials made of fibers, nonwoven fabrics, films and sheets made from nylon or activated carbon are used. In this embodiment, these sheet-like members 24 are processed into a bag shape. Further, the gloves 26 provided on the sheet-like member 24 are also formed of the same material as that of the sheet-like member 24. Among the raw materials, nylon is particularly effective for adsorption of hydrogen peroxide components, is inexpensive, and has an excellent property of being easily processed into a bag shape.

前記構成に係るアイソレータ１の作用について説明する。前記袋状のシート状部材２４は、除染袋（図示せず）に収納した状態で外部から電子線やガンマ線等による放射線除染が施され、予め滅菌された無菌包装の状態で、搬入口１４を開放して除染室２に供給される。袋状のシート状部材２４を収納した除染袋は、除染室２内で過酸化水素蒸気等の除染ガスにより外面が除染され、無菌エアでエアレーションされた後、作業室４との間の図示しない密閉扉を開放して作業室４に供給される。   The operation of the isolator 1 having the above configuration will be described. The bag-like sheet-like member 24 is stored in a decontamination bag (not shown), and is subjected to radiation decontamination from the outside by an electron beam, gamma ray, etc. 14 is opened and supplied to the decontamination chamber 2. The decontamination bag containing the bag-like sheet-like member 24 is decontaminated in the decontamination chamber 2 with a decontamination gas such as hydrogen peroxide vapor and aerated with aseptic air. A sealed door (not shown) is opened and supplied to the work chamber 4.

作業室４では、グローブ１６を介して作業者が前記シート状部材２４を収納した包装を破って、内部の袋状シート状部材２４を取り出す。このシート状部材２４の上部２４ｂを、作業室４の天井４ｂに取り付けられている吊り具２０に取り付けて吊り下げた状態にする。この実施例では、吊り下げたシート状部材２４の下部２４ａが、前記作業台１８の上面を覆う長さを有しており、処理を行う処理対象物２８を作業台１８上に載せると、この処理対象物２８の周囲を覆うことができる。図２に示すように、作業台１８に載せた処理対象物２８を袋状のシート状部材２４で覆った状態にして、作業室４の壁面４ａに取り付けられているグローブ１６に手を挿入し、さらに、このグローブ１６ごと袋状のシート状部材２４に設けられている手袋２６内に挿入して、袋状のシート状部材２４の内部で前記処理対象物２８の処理を行う。   In the work chamber 4, an operator breaks the package containing the sheet-like member 24 through the globe 16 and takes out the bag-like sheet-like member 24 inside. The upper portion 24b of the sheet-like member 24 is attached to the hanging tool 20 attached to the ceiling 4b of the work chamber 4 and is suspended. In this embodiment, the lower part 24a of the suspended sheet-like member 24 has a length that covers the upper surface of the workbench 18, and when the processing object 28 to be processed is placed on the workbench 18, The periphery of the processing object 28 can be covered. As shown in FIG. 2, the processing object 28 placed on the work table 18 is covered with a bag-like sheet-like member 24, and a hand is inserted into the glove 16 attached to the wall surface 4 a of the work chamber 4. Further, the glove 16 is inserted into a glove 26 provided on the bag-like sheet-like member 24, and the processing object 28 is processed inside the bag-like sheet-like member 24.

アイソレータ１の処理作業を行う作業室４内は、除染を行った後、無菌エアを供給してエアレーションにより前記過酸化水素蒸気等の除染ガスを除去しているが、前記作業用のグローブ１６やシール部（図示せず）等の構造体に除染ガス成分が浸透しており、この除染ガス成分が時間の経過とともに再放出される。しかしながら、この実施例装置では、処理される処理対象物２８を過酸化水素ガスを吸着しやすいナイロン製の袋状シート状部材２４で覆っているので、作業室４内に再放出された除染ガスは、前記袋状のシート状部材２４に吸着されるため、その内側の前記処理対象物２８に影響を与えることはない。また、グローブ１６は、袋状のシート部材２４と同じ材質の手袋２６に覆われているため、グローブ１６から再放出される除染ガスは手袋２６に吸着され、処理作業中に有害成分が処理対象物２８に悪影響を及ぼすことはない。   In the work chamber 4 where the processing operation of the isolator 1 is performed, after decontamination, aseptic air is supplied and decontamination gas such as hydrogen peroxide vapor is removed by aeration. The decontamination gas component has permeated into structures such as 16 and a seal portion (not shown), and this decontamination gas component is re-released over time. However, in this embodiment apparatus, since the processing object 28 to be processed is covered with the nylon bag-like sheet-like member 24 that easily adsorbs the hydrogen peroxide gas, the decontamination re-released into the working chamber 4. Since the gas is adsorbed by the bag-like sheet-like member 24, the gas does not affect the processing object 28 inside. Further, since the glove 16 is covered with a glove 26 made of the same material as the bag-like sheet member 24, the decontamination gas re-released from the glove 16 is adsorbed by the glove 26, and harmful components are treated during the processing operation. The object 28 is not adversely affected.
