＜第１実施形態＞
　図１、図２を用いて、第１実施形態の内視鏡用保護具（以下、「保護具」ということがある。）１について説明する。なお、以下の説明において、各実施形態に基づく図面は、模式図である。各部分の厚みと幅との関係、夫々の部分の厚みの比率などは現実のものとは異なることに留意すべきである。図面の相互間においても互いの寸法の関係や比率が異なる部分が含まれている場合がある。一部の構成要素の図示、符号の付与は省略する場合がある。 <First Embodiment>
The endoscope protective device (hereinafter, may be referred to as “protective device”) 1 of the first embodiment will be described with reference to FIGS. 1 and 2. In the following description, the drawings based on each embodiment are schematic views. It should be noted that the relationship between the thickness and width of each part, the ratio of the thickness of each part, etc. are different from the actual ones. There may be parts where the dimensional relationships and ratios of the drawings are different from each other. Illustration of some components and addition of reference numerals may be omitted.
＜内視鏡用保護具の構成＞
　内視鏡９０は、挿入部９１と操作部９２とユニバーサルコード９３とを有する。被検者１００の体内に挿入される挿入部９１の先端部９１Ａには、撮像装置（不図示）が配置されている。 <Structure of protective equipment for endoscopes>
The endoscope 90 has an insertion unit 91, an operation unit 92, and a universal cord 93. An imaging device (not shown) is arranged at the tip 91A of the insertion portion 91 to be inserted into the body of the subject 100.
　保護具１は、被検者１００に装着され、体との間に略密閉された空間を形成するマスク本体５を具備する。マスク本体５は、鼻および口を覆うように、顔面に密着する。マスク本体５は、紐１９を用いて頭部に固定されている。紐１９は、耳にかけられていてもよいし、頭後部だけでなく頭頂部にもかけられていてもよいし、弾性材料で構成されていてもよい。また、マスク本体５の弾性もしくは構造、または、粘着部材（テープなど）によって、マスク本体５が顔面に固定されてもよい。 The protective device 1 is attached to the subject 100 and includes a mask body 5 that forms a substantially sealed space between the subject and the body. The mask body 5 is in close contact with the face so as to cover the nose and mouth. The mask body 5 is fixed to the head using a string 19. The string 19 may be hung on the ear, may be hung not only on the back of the head but also on the top of the head, or may be made of an elastic material. Further, the mask body 5 may be fixed to the face by the elasticity or structure of the mask body 5 or an adhesive member (tape or the like).
　マスク本体５の形状は、空気の循環をよくするため形成される内部空間の体積が小さく、かつ、口および鼻が、マスク本体５に接触しないように設定される。内視鏡９０が経口挿入される場合には、マスク本体５の形状はマウスピースを装着した被検者１００を前提として設計される。 The shape of the mask body 5 is set so that the volume of the internal space formed to improve air circulation is small and the mouth and nose do not come into contact with the mask body 5. When the endoscope 90 is orally inserted, the shape of the mask body 5 is designed on the premise of the subject 100 wearing the mouthpiece.
　保護具１は、少なくとも第１のポート１０と第２のポート２０とを具備する。 The protective device 1 includes at least the first port 10 and the second port 20.
　内視鏡９０の挿入部９１が挿入される第１のポート１０は、被検者１００の口および鼻に対向する位置に１つ設けられている。第１のポート１０は、経鼻および経口での内視鏡挿入を想定した大きさ、および、位置に設置している。そして、第１のポート１０は、内視鏡挿入中に飛沫やエアロゾルの流出を防ぐため、リング１０Ａに配設されているシャッター６を有する。 One first port 10 into which the insertion portion 91 of the endoscope 90 is inserted is provided at a position facing the mouth and nose of the subject 100. The first port 10 is sized and positioned for nasal and oral endoscopic insertion. The first port 10 has a shutter 6 arranged on the ring 10A in order to prevent droplets and aerosol from flowing out during insertion of the endoscope.
　第１のポート１０のシャッター６は、マスク本体５の内部の密閉性を損なうことのないように、放射線状のスリットＳＬによって分割された複数の舌片からなる。シャッター６の材料としては、挿入部９１の外周面を傷付けないように挿入部９１の外周面を構成する外皮よりも柔らかく、かつ、弾性がある、例えば、樹脂またはゴムが好適である。 The shutter 6 of the first port 10 is composed of a plurality of tongue pieces divided by a radial slit SL so as not to impair the airtightness inside the mask body 5. As the material of the shutter 6, for example, resin or rubber, which is softer and more elastic than the outer skin constituting the outer peripheral surface of the insertion portion 91 so as not to damage the outer peripheral surface of the insertion portion 91, is suitable.
　挿入部９１が第１のポート１０に挿入されると、シャッター６の複数の舌片は、挿入部９１の外周面と当接し弾性変形する。挿入部９１の周囲に大きな開口が生じることはない。 When the insertion portion 91 is inserted into the first port 10, the plurality of tongue pieces of the shutter 6 come into contact with the outer peripheral surface of the insertion portion 91 and elastically deform. No large opening is created around the insertion portion 91.
　保護具１は、筒状の第２のポート２０を経由して外気がマスク本体５の内部の略密閉されている空間に流入する。 The protective device 1 allows outside air to flow into a substantially sealed space inside the mask body 5 via the second cylindrical port 20.
　保護具１は、被検者１００による自発的な外気吸入を妨げることのないマスク本体５によって、被検者が発生する飛沫、エアロゾル等がマスク本体５の内部の略密閉空間に留まり、周囲に放出されにくい。このため、保護具１は、医療従事者の感染リスクを低減することができる。外気は、検査室／処置室の空気であるが、ガスボンベ等から共有される酸素等でもよい。 The protective device 1 is a mask body 5 that does not prevent the subject 100 from spontaneously inhaling outside air, so that droplets, aerosols, and the like generated by the subject stay in a substantially enclosed space inside the mask body 5 and surround the mask body 1. Hard to be released. Therefore, the protective device 1 can reduce the risk of infection of the medical staff. The outside air is the air in the examination room / treatment room, but may be oxygen or the like shared from a gas cylinder or the like.
　さらに、保護具１は、筒状の第３のポート３０を具備する。第３のポート３０を経由してマスク本体５の内部空間の空気が吸引される。例えば、第３のポート３０が吸引チューブ２１０によって、吸引器２００と接続される。吸引器２００に替えて、部屋の壁に配置されている減圧管を接続してもよいことは言うまでも無い。空気だけでなく、空気中に飛散している飛沫、エアロゾル等も吸引されることは言うまでも無い。すなわち、マスク本体５の内部の空間にある物質が吸引される。 Further, the protective device 1 is provided with a cylindrical third port 30. Air in the internal space of the mask body 5 is sucked through the third port 30. For example, the third port 30 is connected to the suction device 200 by a suction tube 210. Needless to say, the pressure reducing tube arranged on the wall of the room may be connected instead of the suction device 200. It goes without saying that not only air but also droplets and aerosols scattered in the air are sucked. That is, the substance in the space inside the mask body 5 is sucked.
保護具１は、マスク本体５の内部空間の空気が吸引されるため、医療従事者の感染リスクを低減することができる。 Since the protective device 1 sucks the air in the internal space of the mask body 5, it is possible to reduce the risk of infection by the medical staff.
　さらに、保護具１には、チューブが挿通される第４のポート４０を具備する。保護具１の第４のポート４０は、カニューレ９８、または、挿管チューブが挿通されているマスク本体５の外周の切り欠きである。カニューレ９８は、第２のポート２０を挿通してもよい。その場合は第２のポート２０の孔はカニューレ９８が挿通できる大きさとする。また、後述する第２のポート２０が有する開口およびアダプタが有する切れ込みもカニューレ９８が挿通できる大きさとする。 Further, the protective device 1 is provided with a fourth port 40 through which the tube is inserted. The fourth port 40 of the protective device 1 is a notch on the outer circumference of the cannula 98 or the mask body 5 into which the intubation tube is inserted. Cannula 98 may be inserted through the second port 20. In that case, the hole of the second port 20 is sized so that the cannula 98 can be inserted. Further, the opening of the second port 20 and the notch of the adapter, which will be described later, are also set to a size that allows the cannula 98 to be inserted.
　なお、本発明の保護具においては、第３のポート３０および第４のポート４０は、必須要素ではない。 In the protective device of the present invention, the third port 30 and the fourth port 40 are not essential elements.
　また、保護具１は、ポート６１、６２を更に具備する。図２に示した保護具１では、ポート６１は使用されないため、アダプタ７１によって塞がれている。第２のポート２０と同じように外気が流入するポート６２には、後述するように、ポート６２の開口の大きさを制限する貫通孔のある流量調整部材であるアダプタ７２が配設されている。 Further, the protective device 1 is further provided with ports 61 and 62. In the protective device 1 shown in FIG. 2, since the port 61 is not used, it is blocked by the adapter 71. As described later, the port 62 into which the outside air flows like the second port 20 is provided with an adapter 72 which is a flow rate adjusting member having a through hole for limiting the size of the opening of the port 62. ..
　なお、内視鏡９０は、先端部９１Ａに開口を有し挿入部９１を挿通するチャンネルチューブ９５を含む。チャンネルチューブ９５の基端側の開口である処置具挿入口Ｈ９５には、開口をふさぐ栓であるアダプタ９６が配設されている。 The endoscope 90 includes a channel tube 95 having an opening in the tip portion 91A and inserting the insertion portion 91. An adapter 96, which is a plug for closing the opening, is disposed at the treatment tool insertion port H95, which is an opening on the base end side of the channel tube 95.
＜内視鏡用保護具の作動方法＞
　図３のフローチャートにそって、保護具１の作動方法を簡単に説明する。 <How to operate the protective equipment for endoscopes>
A method of operating the protective device 1 will be briefly described with reference to the flowchart of FIG.
＜ステップＳ１０＞装着工程
　保護具１のマスク本体５が、顔面との間に略密閉された空間が形成される状態に、被検者１００に装着される。 <Step S10> Wearing step The mask body 5 of the protective device 1 is mounted on the subject 100 in a state where a substantially sealed space is formed between the mask body 5 and the face.
　マスク本体５は、塩化ビニルまたはシリコンゴム等の顔面に確実に密着でき、密閉性が担保できる柔軟な材料で構成されている。 The mask body 5 is made of a flexible material such as vinyl chloride or silicone rubber that can be reliably adhered to the face and can ensure hermeticity.
　マスク本体５は、鼻に固定させるために、鼻と対向する領域が、予め鼻の形状に曲がっていることが好ましい。また、鼻と対向する領域が、被検者の鼻の形状に合わせて曲げることができる折り曲げ自由な素材であるマリアブル素材によって構成されていてもよい。 In order to fix the mask body 5 to the nose, it is preferable that the region facing the nose is bent in advance in the shape of the nose. Further, the region facing the nose may be made of a mariable material which is a freely bendable material that can be bent according to the shape of the nose of the subject.
　個人差に応じた大きさのマスク本体５が準備されている。なお、全体形状を調整できるように、マスク本体５の外周部は折り曲げ自由な素材であるマリアブルな素材によって構成されていてもよい。 A mask body 5 of a size according to individual differences is prepared. The outer peripheral portion of the mask body 5 may be made of a mariable material which is a freely bendable material so that the overall shape can be adjusted.
　第１のポート１０は、マスク本体５の中心の開口に配設された円形のリング（円筒）１０Ａと、リング１０Ａに取り付けられたシャッター６と、を含む。リング１０Ａは、ナイロン、ポリアセタール、または、ポリプロピレンなど剛性のある樹脂からなる。シャッター６は、放射線状のスリットＳＬのあるいわゆる菊割れゴムからなる。マスク本体５は、第１のポート１０の開口があるが、リング１０Ａによって機械的強度が担保され、形状が維持されている。第１のポート１０のシャッター６は、用途に応じて交換可能である。 The first port 10 includes a circular ring (cylinder) 10A arranged in the central opening of the mask body 5 and a shutter 6 attached to the ring 10A. The ring 10A is made of a rigid resin such as nylon, polyacetal, or polypropylene. The shutter 6 is made of so-called chrysanthemum cracking rubber having radial slits SL. The mask body 5 has an opening of the first port 10, but the mechanical strength is guaranteed by the ring 10A and the shape is maintained. The shutter 6 of the first port 10 can be replaced depending on the application.
　なお、手術室等で使用されることも想定されるため、保護具１は滅菌処理されて袋にパッキングされていることが好ましい。 Since it is expected to be used in an operating room or the like, it is preferable that the protective device 1 is sterilized and packed in a bag.
　＜ステップＳ２０＞挿入工程
　挿入部９１が第１のポート１０を経由して被検者１００の体内に挿入される。 <Step S20> Insertion step The insertion unit 91 is inserted into the body of the subject 100 via the first port 10.

The shutter 6 of the first port 10 is not limited to the so-called chrysanthemum cracked rubber having a radial slit SL so as not to deteriorate the degree of sealing of the substantially sealed space of the protective device 1. The shutter 6 shown in FIGS. 4A and 4B has a straight slit SL. The shutter 6 shown in FIG. 4C has an opening H11 for an oral endoscope, a cover 11A closing the opening H11, an opening H12 for a nasal endoscope, and a cover 12A closing the opening H12. Have. The shutter 6 shown in FIGS. 4D and 4E has a slit SL11 for an oral endoscope and a slit SL12 for a nasal endoscope. The shutter 6 shown in FIG. 4F has only an opening H11 for an oral endoscope.
　すなわち、第１のポート１０の開口は、被検者の口または鼻の少なくともいずれかに対向する位置に少なくとも１つ設けられていればよい。第１のポート１０の開口は、経口および経鼻に対応できるため、口および鼻に対向する位置に１つ設けられていることが好ましい。 That is, at least one opening of the first port 10 may be provided at a position facing at least one of the subject's mouth or nose. It is preferable that one opening of the first port 10 is provided at a position facing the mouth and the nose because it can be used for oral and nasal purposes.
　シャッター６は、第１のポート１０から取り外し可能であることが好ましい。また、第１のポート１０に複数のシャッター６が重ねて取り付けされていてもよい。 It is preferable that the shutter 6 is removable from the first port 10. Further, a plurality of shutters 6 may be mounted on the first port 10 in an overlapping manner.
　なお、検査前および検査後、すなわち、被検者１００が保護具１を装着し待機している間に、飛沫が漏れることを防ぐため、図４Ｃに示すカバー１１Ａを有するシャッターのように、開口を完全に塞げる構成を有する保護具が好ましい。 It should be noted that before and after the inspection, that is, while the subject 100 is wearing the protective device 1 and waiting, in order to prevent droplets from leaking, an opening like a shutter having a cover 11A shown in FIG. 4C. A protective device having a structure that completely closes the surface is preferable.
　例えば、シャッター６を、写真撮影用レンズの虹彩絞りと同じように複数の絞り羽根を有する構成とすることによって、開口サイズが調整できる。７枚の羽根を有するシャッター６では７角形の開口が形成されるが、開口を完全に閉じることもできる。 For example, the aperture size can be adjusted by configuring the shutter 6 to have a plurality of diaphragm blades in the same manner as the iris diaphragm of a photography lens. The shutter 6 with seven blades forms a heptagonal opening, but the opening can also be closed completely.
　また、開口を有するシャッター６に、第２のシャッターとして、延性に優れたビニル樹脂、または、布のように、柔らかく、かつ、通気しない素材からなるカバーを重ねてもよい。 Further, as the second shutter, a cover made of a vinyl resin having excellent ductility or a soft and non-ventilating material such as cloth may be placed on the shutter 6 having an opening.
　例えば、検査前および検査後には、被検者１００の口および鼻に対向する位置に孔のあるシャッター６の全面を塞ぐように、カバーがマスク本体５に配設されている。検査時には、カバーの位置をずらしたり、折り返したりすることで、孔の上半分または下半分が露出する。 For example, before and after the inspection, a cover is arranged on the mask body 5 so as to close the entire surface of the shutter 6 having a hole at a position facing the mouth and nose of the subject 100. During inspection, the upper or lower half of the hole is exposed by shifting or folding the cover.
＜第２のポート、第３のポートの変形例＞
　空気の経路となるポート、例えば第２のポート２０または第３のポート３０の少なくともいずれかは、流量が調整できることが好ましい。 <Modification example of the second port and the third port>
It is preferable that the flow rate of at least one of the ports serving as the air path, for example, the second port 20 or the third port 30, can be adjusted.
　図５Ａに示す第２のポート２０は、マスク本体５との接合部の断面積が、先端部の断面積よりも広い。マスク本体５が被検者の頬に密着した場合、第２のポート２０が塞がれて、十分な換気ができなくなるおそれがある。底面が広がっているポートは被検者の顔表面によって第２のポート２０が塞がれることが少なくなる。 The cross-sectional area of the joint portion of the second port 20 shown in FIG. 5A with the mask body 5 is wider than the cross-sectional area of the tip portion. If the mask body 5 is in close contact with the cheek of the subject, the second port 20 may be blocked and sufficient ventilation may not be possible. In the port having a wide bottom surface, the second port 20 is less likely to be blocked by the face surface of the subject.
　また、第２のポート２０は、吸引チューブまたは各種のルアーコネクタが接合される、ポートから取り外し可能なアダプタ７２Ａを有している。 Further, the second port 20 has an adapter 72A that can be removed from the port to which a suction tube or various luer connectors are joined.
　図５Ｂに示す第２のポート２０は、側面に開口Ｗ２０を有し、つば（傘）付きの栓である円筒状のアダプタ７１Ａを有する。アダプタ７１Ａを孔Ｈ２０に押し込む深さを調整することによって開口Ｗ２０の大きさ、すなわち、流量を調整できる。つば付きのアダプタ７１Ａは、孔Ｈ２０に深く押し込まれることがないため、マスク本体５の内面から突出することがない。またアダプタ７１Ａが後述するオリフィス板に突き当らないことによって、オリフィス板が有する孔がアダプタ７１Ａで塞がれることがない。さらに、第２のポート２０は、側面に開口があるため、直接的な飛沫拡散を防ぐことができる。なお、図２に示したアダプタ７１、７２または図５Ａに示したアダプタ７２Ａも、つばを有していてもよい。 The second port 20 shown in FIG. 5B has an opening W20 on the side surface and a cylindrical adapter 71A which is a stopper with a brim (umbrella). The size of the opening W20, that is, the flow rate can be adjusted by adjusting the depth at which the adapter 71A is pushed into the hole H20. Since the adapter 71A with a brim is not pushed deeply into the hole H20, it does not protrude from the inner surface of the mask body 5. Further, since the adapter 71A does not abut on the orifice plate described later, the hole of the orifice plate is not blocked by the adapter 71A. Further, since the second port 20 has an opening on the side surface, it is possible to prevent direct splash diffusion. The adapters 71 and 72 shown in FIG. 2 or the adapter 72A shown in FIG. 5A may also have a brim.
　図５Ｃに示す第２のポート２０のアダプタ７３は、切れ込みのある当接部７３Ａと、円筒状の当接部７３Ｂと、を有する。当接部７３Ａを孔Ｈ２０に押し込む深さを調整することによって流量を調整できる。アダプタ７３は、当接部７３Ａを回転することによって換気口である切れ込みを医療従事者がいない方向に向けることができ、医療従事者がいない方向に換気できる。つばには、切れ込みの方向を示すマーク（矢印など）を有することが好ましい。また、当接部７３Ｂを孔Ｈ２０に押し込むと流路を遮断できる。 The adapter 73 of the second port 20 shown in FIG. 5C has a notched contact portion 73A and a cylindrical contact portion 73B. The flow rate can be adjusted by adjusting the depth at which the contact portion 73A is pushed into the hole H20. By rotating the contact portion 73A, the adapter 73 can direct the notch, which is a ventilation port, in the direction in which the medical staff is not present, and can ventilate in the direction in which the medical staff is not present. The brim preferably has a mark (such as an arrow) indicating the direction of the notch. Further, when the contact portion 73B is pushed into the hole H20, the flow path can be blocked.
　図５Ｂに示した側面に開口Ｗ２０を有する第２のポート２０と、図５Ｃに示した切れ込みを有するアダプタ７３を組み合わせてもよい。第２のポート２０の開口Ｗ２０とアダプタ７３の切れ込みとの重なり状態を変えることによって、換気の方向と流量を調整することができる。 A second port 20 having an opening W20 on the side surface shown in FIG. 5B may be combined with an adapter 73 having a notch shown in FIG. 5C. By changing the overlapping state of the opening W20 of the second port 20 and the notch of the adapter 73, the direction of ventilation and the flow rate can be adjusted.
　また、図６Ａに示す第２のポート２０は、孔Ｈ２０の中に複数の円形の孔Ｈ２０Ａを有するオリフィス板を有する。図６Ｂに示す第２のポート２０は、孔Ｈ２０の中に複数の楕円形の孔Ｈ２０Ａを有するオリフィス板を有する。また、上記オリフィス板は、カニューレ９８が挿通できる大きさの孔を一つのみ有していてもよい。 Further, the second port 20 shown in FIG. 6A has an orifice plate having a plurality of circular holes H20A in the holes H20. The second port 20 shown in FIG. 6B has an orifice plate having a plurality of elliptical holes H20A in the holes H20. Further, the orifice plate may have only one hole having a size through which the cannula 98 can be inserted.
　上記第２のポート２０と同じ構成を、第３のポート３０が有していてもよい。また、ポートは、逆止弁を有していてもよい。また、ポートは、ろ過効率の高いフィルタ（Ｎ９５など）を有していてもよい。 The third port 30 may have the same configuration as the second port 20 described above. Also, the port may have a check valve. Further, the port may have a filter having high filtration efficiency (N95 or the like).
＜ポートの数、配置の変形例＞
　保護具１では、マスク本体５によって形成された空間は、ポートによってだけ外部とつながっている略密閉された空間である。 <Example of modification of the number of ports and arrangement>
In the protective device 1, the space formed by the mask body 5 is a substantially sealed space connected to the outside only by a port.
　保護具１は、少なくとも１つの第１のポート１０と１つの第２のポート２０とを有していれば、被検者１００による自発的な外気吸入を妨げることなく、医療従事者の感染リスクを低減することができる。 If the protective device 1 has at least one first port 10 and one second port 20, it does not prevent the subject 100 from spontaneously inhaling outside air, and the risk of infection of the medical staff is not prevented. Can be reduced.
　また、第３のポート３０を有する場合には、マスク本体５の内部空間の空気の流れを考慮することで、最も効果的なポート配置が得られる。例えば、図２に示したように、図面においてマスク本体５の左側に第２のポート２０を有し、マスク本体５の右側に第３のポート３０を有している場合には、空気は、マスク本体５の内部空間の中を左から右に向かって流れる。 Further, when the third port 30 is provided, the most effective port arrangement can be obtained by considering the air flow in the internal space of the mask main body 5. For example, as shown in FIG. 2, when the drawing has the second port 20 on the left side of the mask body 5 and the third port 30 on the right side of the mask body 5, the air is. It flows from left to right in the internal space of the mask body 5.
　図７に示す保護具１では、マスク本体５の上部に４つの第２のポート２０を有し、マスク本体５の下部に２つの第３のポート３０を有する。空気は、マスク本体５の上から下に内部空間の中を流れる。図８に示すようにマスク本体５の右上に第２のポート２０を有し、マスク本体５の左下に第３のポート３０を有している場合には、空気は、マスク本体５の内部空間の中を右上から左下に流れる。 The protective device 1 shown in FIG. 7 has four second ports 20 at the upper part of the mask main body 5 and two third ports 30 at the lower part of the mask main body 5. Air flows in the internal space from the top to the bottom of the mask body 5. As shown in FIG. 8, when the mask main body 5 has the second port 20 on the upper right and the third port 30 on the lower left of the mask main body 5, the air is the internal space of the mask main body 5. It flows from the upper right to the lower left.
　また、図８に示す保護具１では、第４のポートは、挿管チューブが挿通する筒４０である。 Further, in the protective device 1 shown in FIG. 8, the fourth port is a cylinder 40 through which the intubation tube is inserted.
　保護具１のポートの数、配置、および形状は、用途に応じて適宜設定される。例えば、耳鼻咽喉頭科分野または消化器分野における使用を想定して、マスク本体５の片側（例えば、右側）にだけ第３のポート３０を有していてもよいし、両側に第３のポート３０を有していてもよい。 The number, arrangement, and shape of the ports of the protective device 1 are appropriately set according to the application. For example, assuming use in the field of otolaryngology or gastrointestinal tract, the mask body 5 may have a third port 30 on only one side (for example, the right side), or a third port on both sides. You may have 30.
　挿入部９１が細径の気管支鏡用の保護具１では、第１のポート１０は第２のポートよりも開口が小さくてもよい。保護具１は、消化器用内視鏡用ポートと気管支鏡用ポートの２つの第１のポート１０を有していてもよい。 In the bronchoscope protective device 1 in which the insertion portion 91 has a small diameter, the opening of the first port 10 may be smaller than that of the second port. The protective device 1 may have two first ports 10 of a gastrointestinal endoscopic port and a bronchoscopic port.
＜マスク本体の外形の変形例＞
　マスク本体５は、被検者の目までを覆っていてもよいし、顔面全体を覆っていてもよい。逆に、手術スペースを確保する為に顔の上半分のみを覆うマスクでもよい。すなわち、図９に示すようにマスク本体５を、図２のマスク本体５の下部を切断した形状とし、鼻近辺のみ、マスク本体５と顔との間に隙間が形成される。鼻近辺以外は隙間ができないように、テープで塞いでもよい。 <Example of deformation of the outer shape of the mask body>
The mask body 5 may cover up to the eyes of the subject, or may cover the entire face. Conversely, a mask that covers only the upper half of the face may be used to secure surgical space. That is, as shown in FIG. 9, the mask body 5 has a shape in which the lower part of the mask body 5 in FIG. 2 is cut off, and a gap is formed between the mask body 5 and the face only in the vicinity of the nose. You may cover it with tape so that there are no gaps except near the nose.
　第３のポート３０は吸引チューブ２１０を経由して吸引器２００と接続される。被検者１００が発生するエアロゾルは、マスク本体５と顔との隙間から吸引されるために、医療従事者の感染リスクを低減できる。図９に示すように吸引チューブ２１０はマスク本体５の中を通して先端が被検者１００の鼻近辺に位置するようにしてもよい。 The third port 30 is connected to the suction device 200 via the suction tube 210. Since the aerosol generated by the subject 100 is sucked from the gap between the mask body 5 and the face, the risk of infection by the medical staff can be reduced. As shown in FIG. 9, the suction tube 210 may be passed through the mask body 5 so that the tip thereof is located near the nose of the subject 100.
　さらに、本発明のマスク本体は、図２に示したマスク本体５の上部を切断した形状、または、上部および下部を切断した形状とすることによって、サイズを小さくしてもよい。 Further, the size of the mask body of the present invention may be reduced by cutting the upper part of the mask body 5 shown in FIG. 2 or cutting the upper part and the lower part.
＜第２実施形態＞
　以降に説明する各実施形態の内視鏡用保護具は、保護具１と類似し、同じ効果を有するため、同じ機能の構成要素には同じ符号を付し説明は省略する。 <Second Embodiment>
Since the endoscope protective device of each embodiment described below is similar to the protective device 1 and has the same effect, the components having the same function are designated by the same reference numerals and the description thereof will be omitted.
　図１０に示す本実施形態の内視鏡用保護具１Ａは、被検者１００の頭から顎までを覆い、本体５の第１のポート１０を覆わない、オーバーマスク（フルフェイスマスク）１５を更に具備する。 The endoscope protective device 1A of the present embodiment shown in FIG. 10 has an overmask (full face mask) 15 that covers the subject 100 from the head to the chin and does not cover the first port 10 of the main body 5. Further equipped.
　オーバーマスク１５は、首が挿通される開口のある透明な袋である。例えば、ポリエチレンフィルムからなるオーバーマスク１５は、マスク本体５の外周部に、例えば、溶着固定され、マスク本体５と一体化されている。被検者１００は、マスク本体５を装着してからオーバーマスク１５を頭にかぶり、首においてオーバーマスク１５の開口を、紐等で縛って固定する。 The overmask 15 is a transparent bag with an opening through which the neck can be inserted. For example, the overmask 15 made of a polyethylene film is welded and fixed to the outer peripheral portion of the mask body 5, for example, and is integrated with the mask body 5. The subject 100 wears the mask body 5 and then puts the overmask 15 on his head, and ties the opening of the overmask 15 around his neck with a string or the like to fix it.
　図１１に示すオーバーマスク１５Ａは、マスク本体５に対応する位置にも、例えば、ゴムが外縁に配設された開口がある。このため、マスク本体５の外周部はオーバーマスク１５Ａに覆われている。 The overmask 15A shown in FIG. 11 also has an opening in which rubber is arranged on the outer edge, for example, at a position corresponding to the mask main body 5. Therefore, the outer peripheral portion of the mask main body 5 is covered with the overmask 15A.
　オーバーマスク１５、１５Ａは被検者１００の上半身を覆っていてもよい。また、オーバーマスク１５、１５Ａに、換気のためのポートを有していてもよい。被検者１００が鼻カニューレ９８等のチューブを装着している場合には、チューブを固定するための固定部およびチューブを挿通するため開口があるオーバーマスク１５、１５Ａが用いられる。 The overmasks 15 and 15A may cover the upper body of the subject 100. Further, the overmasks 15 and 15A may have a port for ventilation. When the subject 100 is wearing a tube such as a nasal cannula 98, overmasks 15 and 15A with a fixing portion for fixing the tube and an opening for inserting the tube are used.
　被検者１００によっては、オーバーマスクを被ると恐怖を感じることがある。このため、オーバーマスクは、頭頂部にも開口を有していてもよい。かかるオーバーマスクでは、検査が始まるまでは、オーバーマスクを目を覆わない状態とし、検査開始直前に、オーバーマスクを頭頂部まで引き延ばし、開口を頭の上でしばることができる。 Depending on the subject 100, wearing an overmask may cause fear. For this reason, the overmask may also have an opening on the crown. With such an overmask, the overmask can be kept uncovered until the start of the examination, and just before the start of the examination, the overmask can be extended to the crown and the opening can be closed over the head.
＜第３実施形態＞
　図１２に示す本実施形態の内視鏡用保護具１Ｂは、第１のポート１０に配設され、内視鏡９０の挿入部９１が略密封状態に収容される挿入部用のドレープ１６を更に具備する。 <Third Embodiment>
The endoscope protector 1B of the present embodiment shown in FIG. 12 has a drape 16 for an insertion portion, which is arranged in the first port 10 and in which the insertion portion 91 of the endoscope 90 is housed in a substantially sealed state. Further equipped.
　ドレープ１６は、第１のポート１０に配設されるリング１６Ａと、両端に開口のある滅菌された筒状の袋であるドレープ１６Ｂと、を具備する。ドレープ１６の長さは、挿入部９１の長さよりも少し長い。図１３に示すように、ドレープ１６の開口のリング１６Ａは、第１のポート１０のリング１０Ａと嵌合することによって、マスク本体５に隙間なく固定される。 The drape 16 includes a ring 16A arranged in the first port 10 and a drape 16B which is a sterilized cylindrical bag having openings at both ends. The length of the drape 16 is slightly longer than the length of the insertion portion 91. As shown in FIG. 13, the ring 16A of the opening of the drape 16 is fixed to the mask body 5 without a gap by fitting with the ring 10A of the first port 10.
　ドレープ１６の操作部９２の側の開口は、挿入部９１の後端部または操作部９２の下部に、例えば、テープ１６Ｃを用いて隙間なく固定されている。なお内視鏡９０が、チャンネルチューブを有する場合には、ドレープ１６は、操作部９２の処置具挿入孔までを覆っていることが好ましい。 The opening on the side of the operation portion 92 of the drape 16 is fixed to the rear end portion of the insertion portion 91 or the lower portion of the operation portion 92 without a gap by using, for example, tape 16C. When the endoscope 90 has a channel tube, it is preferable that the drape 16 covers up to the treatment tool insertion hole of the operation unit 92.
　内視鏡検査では、挿入部９１の先端部９１Ａを体内の最深部まで挿入した後に、少しずつ抜去しながら観察が行われる。しかし、被検者１００の体内に挿入された挿入部９１は、ウイルス等が表面に付着しているおそれがある。 In endoscopy, after inserting the tip 91A of the insertion part 91 to the deepest part of the body, observation is performed while gradually removing it. However, the insertion portion 91 inserted into the body of the subject 100 may have a virus or the like attached to the surface thereof.
　保護具１Ｂは、挿入部９１がドレープ１６に密封されているために、医療従事者の感染リスクを低減できる。 Since the insertion portion 91 of the protective device 1B is sealed to the drape 16, the risk of infection by medical staff can be reduced.
　ドレープ１６Ｂは、挿入部９１を把持し操作するために柔軟な素材でできている。また、ドレープ１６Ｂは、かさばらないように、薄い素材でできている。例えば、ドレープ１６Ｂはポリエチレン等の透明または半透明の柔軟な樹脂材料により構成されている。筒状のドレープ１６Ｂの断面積は、リング１６Ａから離れるにしたがい、大きくなっていてもよいし、小さくなっていてもよい。 The drape 16B is made of a flexible material for gripping and operating the insertion portion 91. Also, the drape 16B is made of a thin material so as not to be bulky. For example, the drape 16B is made of a transparent or translucent flexible resin material such as polyethylene. The cross-sectional area of the cylindrical drape 16B may be larger or smaller as it is separated from the ring 16A.
　図１４に示すように、挿入部９１が体内に挿入されるにつれ、ドレープ１６Ｂは、例えば、蛇腹状に折りたたまれていく。そして、挿入部９１が抜去されると、ドレープ１６Ｂは、筒状に戻る。 As shown in FIG. 14, as the insertion portion 91 is inserted into the body, the drape 16B is folded into a bellows shape, for example. Then, when the insertion portion 91 is removed, the drape 16B returns to a cylindrical shape.
　すなわち、保護具１Ｂの作動方法では、挿入工程および抜去工程において、挿入部９１は、第１のポート１０と連通している挿入部用のドレープ１６に収容されることによって密封されている。 That is, in the method of operating the protective device 1B, the insertion portion 91 is sealed by being housed in the drape 16 for the insertion portion communicating with the first port 10 in the insertion step and the removal step.
　内視鏡９０を抜去した後に、マスク本体５のポートは、アダプタによって塞がれる。そして、例えば、マスク本体５がオーバーマスク１５とともに用いられる場合には、被検者から取り外されたオーバーマスク１５の首側の開口を縛ることによって、挿入部９１はマスク本体５とともに密封される（図１５） After removing the endoscope 90, the port of the mask body 5 is blocked by the adapter. Then, for example, when the mask body 5 is used together with the overmask 15, the insertion portion 91 is sealed together with the mask body 5 by binding the opening on the neck side of the overmask 15 removed from the subject (for example). FIG. 15)
　挿入部用のドレープ１６によって、医療従事者は、挿入部９１に触れること無く、検査、処理を完遂できる。また、挿入部用のドレープ１６は、滅菌処理等を行うリプロセス室までの移動中およびリプロセス室における、拡散リスクを低減できる。 The drape 16 for the insertion part allows the medical staff to complete the inspection and processing without touching the insertion part 91. Further, the drape 16 for the insertion portion can reduce the risk of diffusion during movement to the reprocess chamber for sterilization and the like and in the reprocess chamber.
　オーバーマスク１５に替えて、袋を用いて、使用後の挿入部６１を密封してもよい。また、マスク本体５からドレープ１６を取り外して、袋を用いて、ドレープ１６のリング１６Ａを覆ってもよい。 Instead of the overmask 15, a bag may be used to seal the inserted portion 61 after use. Alternatively, the drape 16 may be removed from the mask body 5 and a bag may be used to cover the ring 16A of the drape 16.
　従来の内視鏡用ドレープ等は、ドレープ内の清浄空間をドレープ外の汚染空間から保護するために用いられていた。これに対して、本発明のドレープは、汚染された部材を略密閉状態で収容するために用いられる。 Conventional endoscope drapes and the like have been used to protect the clean space inside the drape from the contaminated space outside the drape. On the other hand, the drape of the present invention is used to house a contaminated member in a substantially sealed state.
　なお、シャッター６が、マスク本体５ではなく、ドレープ１６のリング１６Ａに、配設されていてもよい。また、マスク本体５ではなく、リング１６Ａに換気のための第２のポートまたは吸引のための第３のポートの少なくともいずれかが配設されていてもよい。 The shutter 6 may be arranged not on the mask body 5 but on the ring 16A of the drape 16. Further, at least one of a second port for ventilation and a third port for suction may be provided on the ring 16A instead of the mask body 5.
　リング１６Ａは、口径が第１のポート１０のリング１０Ａとの接続部から離れるにしたがい、口径が小さくなっている円錐形でもよし、縦長、横長、または十字形の漏斗形状でもよい。上記形状のリング１６Ａを有するドレープ１６では、内視鏡挿入時に、蛇腹になったドレープ１６Ｂが、マスク本体５Ａの中に入り込み、被検者１００の口および鼻に接してしまうことがない。また、上記ドレープ１６は、使用前の畳まれた状態のドレープ１６Ｂを、使用時に筒状に引きだすことが容易である。 The ring 16A may have a conical shape with a smaller diameter, a vertically long, horizontally long, or a cruciform funnel shape as the diameter increases away from the connection portion of the first port 10 with the ring 10A. In the drape 16 having the ring 16A having the above-mentioned shape, the bellows drape 16B does not enter the mask body 5A and come into contact with the mouth and nose of the subject 100 when the endoscope is inserted. Further, the drape 16 can easily pull out the folded drape 16B before use into a cylindrical shape at the time of use.
＜第４実施形態＞
　図１６に示す内視鏡は挿入部９１の先端部９１Ａから操作部９２の処置具挿入口Ｈ９５まで延設されているチャンネルチューブ９５を有する。処置具用のドレープ１７は、チャンネルチューブ９５に挿入される処置具９９が収容される。 <Fourth Embodiment>
The endoscope shown in FIG. 16 has a channel tube 95 extending from the tip portion 91A of the insertion portion 91 to the treatment tool insertion port H95 of the operation portion 92. The drape 17 for the treatment tool accommodates the treatment tool 99 inserted into the channel tube 95.
　ドレープ１７は、挿入部用のドレープ１６と同じように、例えば、ポリエチレンにより構成されている筒である。ドレープ１７の長さは、処置具９９の長さと略同じである。 The drape 17 is a cylinder made of, for example, polyethylene, like the drape 16 for the insertion portion. The length of the drape 17 is substantially the same as the length of the treatment tool 99.
　ドレープ１７の一方の開口は、処置具挿入口Ｈ９５を密閉するように操作部９２の下部を覆っている。ドレープ１７の他方の開口は処置具９９の端部を密閉するように、ゴム１７Ａ等を用いて固定されている。なお、図１６に示したドレープ１７では、処置具９９の端部はドレープ１７に収容されていないが、処置具９９の全体がドレープ１７に収容されていてもよい。 One opening of the drape 17 covers the lower part of the operation unit 92 so as to seal the treatment tool insertion port H95. The other opening of the drape 17 is fixed by using rubber 17A or the like so as to seal the end portion of the treatment tool 99. In the drape 17 shown in FIG. 16, the end portion of the treatment tool 99 is not housed in the drape 17, but the entire treatment tool 99 may be housed in the drape 17.
　図１７に示すように、処置具９９がチャンネルチューブ９５に挿入され、処置具９９の先端が、挿入部９１の先端部９１Ａの開口から突出する状態になると、ドレープ１７は、例えば、蛇腹状に折りたたまれていく。 As shown in FIG. 17, when the treatment tool 99 is inserted into the channel tube 95 and the tip of the treatment tool 99 protrudes from the opening of the tip portion 91A of the insertion portion 91, the drape 17 becomes, for example, a bellows shape.
