The medical device cover 1 is housed in a sterilization bag (not shown) in a state of being sterilized in advance using a known sterilization method suitable for the material of the drape 2 and the flap 5.
　本実施形態の医療機器用カバー１は、手術室に持ち込まれる医療機器に取り付けることができる。本実施形態の医療機器用カバー１を取り付ける対象となる医療機器の例として、医療用マニピュレータのコンソールや器具台等を挙げることができる。また、医療機器用カバー１は、医療機器において水平な面や垂直な面など（例えば図４の水平面１０１及び垂直面１０２参照）、医療機器１００の表面のどこにでも取り付けることができる。本明細書では、医療機器１００における垂直面１０２に医療機器用カバー１を取付ける場合について例示する。 The medical device cover 1 of the present embodiment can be attached to a medical device brought into the operating room. Examples of medical devices to which the medical device cover 1 of the present embodiment is attached include a console of a medical manipulator, an instrument table, and the like. Further, the medical device cover 1 can be attached anywhere on the surface of the medical device 100 such as a horizontal surface or a vertical surface (see, for example, the horizontal surface 101 and the vertical surface 102 in FIG. 4). In this specification, the case where the medical device cover 1 is attached to the vertical surface 102 of the medical device 100 is illustrated.
　滅菌バッグから取り出された医療機器用カバー１は、作業者の手作業によって平面状に展開される。さらに、図５から図７までに示すように、医療機器用カバー１のフィルム３の第一面３ａが医療機器１００の表面に面するように、フィルム３が医療機器１００に取り付けられる。フィルム３の第一面３ａに固定された第一固定部４ａ及び第二固定部４ｂが医療機器１００の表面に付着することによって、フィルム３は医療機器１００に固定される。このとき、フィルム３の第二面３ｂは、医療機器１００を保護すべき汚染源に面する。フィルム３の第二面３ｂは、汚染源となる体液等が付着し得る面となっている。 The medical device cover 1 taken out from the sterilization bag is unfolded in a planar shape by the operator's manual work. Furthermore, as shown in FIGS. 5 to 7, the film 3 is attached to the medical device 100 such that the first surface 3 a of the film 3 of the medical device cover 1 faces the surface of the medical device 100. The film 3 is fixed to the medical device 100 when the first fixing portion 4a and the second fixing portion 4b fixed to the first surface 3a of the film 3 adhere to the surface of the medical device 100. At this time, the second surface 3 b of the film 3 faces a contamination source that should protect the medical device 100. The second surface 3b of the film 3 is a surface to which a body fluid or the like that becomes a contamination source can adhere.
　医療機器用カバー１が医療機器１００に取り付けられている状態において、フラップ５のうち、山折り部７が突出する側の面（以下、この面を表面という）とは反対側の面（以下、この面を裏面という）は、フィルム３の第一面３ａと同じ方向に向けられている。このため、フラップ５の裏面は、医療機器１００の表面に接触し得る面である。また、フラップ５の把持部（山折り部７）は、医療機器１００の表面から離間している。本実施形態の場合には、フラップ５は医療機器１００の表面に接触する場合があるが、付着はしない。 In the state in which the medical device cover 1 is attached to the medical device 100, the surface (hereinafter referred to as the surface) opposite to the surface of the flap 5 from which the mountain fold 7 projects (hereinafter referred to as the surface). This surface is referred to as the back surface) and is directed in the same direction as the first surface 3 a of the film 3. For this reason, the back surface of the flap 5 is a surface that can contact the surface of the medical device 100. Further, the grip portion (mountain fold portion 7) of the flap 5 is separated from the surface of the medical device 100. In the case of this embodiment, the flap 5 may contact the surface of the medical device 100, but it does not adhere.
　医療機器用カバー１を医療機器１００から取り外す場合において、医療機器用カバー１を取り外す作業者は、フラップ５に設けられた把持部（山折り部７）を把持することによって、医療機器１００の表面に接触することなくドレープ２を医療機器１００の表面から離間させることができる。図７に示すように、フラップ５に設けられた把持部（山折り部７）を把持する時には、把持するための２つの指がそれぞれ一端部側（第一把持面７ａ）と延長部８側（第二把持面７ｂ）に配される。このため、フラップ５の一端部６及び延長部８に指先Ｆが接触する場合がある。この場合においても、指先は医療機器１００には直接接触しないので、医療機器１００の表面の清潔状態は維持される。 When removing the medical device cover 1 from the medical device 100, an operator who removes the medical device cover 1 grips the grip portion (mountain fold portion 7) provided on the flap 5, whereby the surface of the medical device 100. The drape 2 can be separated from the surface of the medical device 100 without touching. As shown in FIG. 7, when gripping the grip portion (mountain fold portion 7) provided on the flap 5, the two fingers for gripping are respectively at one end side (first grip surface 7 a) and the extension portion 8 side. It is arranged on the (second gripping surface 7b). For this reason, the fingertip F may contact the one end portion 6 and the extension portion 8 of the flap 5. Even in this case, since the fingertip does not directly contact the medical device 100, the clean state of the surface of the medical device 100 is maintained.
　医療機器用カバー１を医療機器１００から取り外す過程において、作業者は、フラップ５の把持部（山折り部７）を把持した状態で、図８に示すように、フラップ５が第一固定部４ａ又は第二固定部４ｂに近付くように、ドレープ２を変形させる。作業者がフラップ５を固定部４側へ移動させることによって、フィルム３は第二面３ｂ同士が向かい合うＵ字状に折り曲げられる。このとき、フィルム３の第二面３ｂに体液等汚染源となる液体が付着している場合には、この液体は、医療機器１００の表面へ流れ出さないようにフィルム３によって保持されている。 In the process of removing the medical device cover 1 from the medical device 100, the operator holds the grip portion (mountain fold portion 7) of the flap 5, and the flap 5 is the first fixing portion 4 a as shown in FIG. 8. Alternatively, the drape 2 is deformed so as to approach the second fixing portion 4b. When the operator moves the flap 5 to the fixed portion 4 side, the film 3 is bent into a U shape in which the second surfaces 3b face each other. At this time, when a liquid that becomes a contamination source such as a body fluid adheres to the second surface 3 b of the film 3, the liquid is held by the film 3 so as not to flow out to the surface of the medical device 100.
　作業者は、第一固定部４ａ及び第二固定部４ｂの近傍のフィルム３を把持して固定部４を医療機器１００の表面から外すことによって、フィルム３の第二面３ｂを医療機器１００の表面に接触させることなくドレープ２を医療機器１００から取り外すことができる。 The operator grasps the film 3 in the vicinity of the first fixing portion 4a and the second fixing portion 4b and removes the fixing portion 4 from the surface of the medical device 100, whereby the second surface 3b of the film 3 is removed from the medical device 100. The drape 2 can be removed from the medical device 100 without contacting the surface.
　以上に説明したように、本実施形態の医療機器用カバー１によれば、フラップ５において把持部（山折り部７）がフィルム３の第一面３ａから第二面３ｂへ向かう方向となる第三方向に沿って第二面３ｂから突出した形状をなしていることによって、医療機器１００の表面に作業者の指が接触しないようにフラップ５を掴むことができる。その結果、本実施形態の医療機器用カバー１によれば、使用後のドレープ２の取り外し作業に起因する医療機器１００の汚染が生じにくい。 As described above, according to the medical device cover 1 of the present embodiment, in the flap 5, the grip portion (mountain fold portion 7) is in the direction from the first surface 3a of the film 3 toward the second surface 3b. By forming the shape protruding from the second surface 3b along the three directions, the flap 5 can be gripped so that the operator's finger does not come into contact with the surface of the medical device 100. As a result, according to the medical device cover 1 of the present embodiment, the medical device 100 is hardly contaminated due to the removal operation of the drape 2 after use.

（第２実施形態）
　本発明の第２実施形態について説明する。以下の各実施形態において、上記の第１実施形態に開示された構成要素と同様の構成要素には、第１実施形態と同一の符号が付され、重複する説明は省略される。図１０は、本実施形態の医療機器用カバーの一部を示す図である。 (Second Embodiment)
A second embodiment of the present invention will be described. In the following embodiments, the same components as those disclosed in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and redundant descriptions are omitted. FIG. 10 is a diagram illustrating a part of the medical device cover according to the present embodiment.
　図１０に示すように、本実施形態の医療機器用カバー１Ａは、第１実施形態に開示された第三固定部４ｃ及び第四固定部４ｄ（図１参照）に代えて、フラップ５の裏面（山折り部７が位置する側とは反対側の面）に粘着層９を有している。
　フラップ５の裏面に配された粘着層９は、医療機器１００の表面１０２ａ（図７参照）にフラップ５を付着させるために使用することができる。粘着層９は、医療機器１００の表面に糊成分が残りにくいものが好ましい。 As shown in FIG. 10, the medical device cover 1 </ b> A according to the present embodiment replaces the third fixing portion 4 c and the fourth fixing portion 4 d (see FIG. 1) disclosed in the first embodiment, and the back surface of the flap 5. An adhesive layer 9 is provided on the surface opposite to the side where the mountain fold 7 is located.
The adhesive layer 9 disposed on the back surface of the flap 5 can be used for attaching the flap 5 to the front surface 102a (see FIG. 7) of the medical device 100. The adhesive layer 9 is preferably a layer in which the adhesive component hardly remains on the surface of the medical device 100.
　本実施形態では、フラップ５の裏面を医療機器１００の表面に粘着層９を用いて付着させることによって、フラップ５を介してフィルム３を医療機器１００に固定することができる。また、本実施形態では、フラップ５の裏面の粘着層９が医療機器１００の表面に付着した状態ではフラップ５の表面側の把持部（山折り部７）は常に医療機器１００から離間した位置にあるので、把持部を作業者が把持する場合に作業者の指が医療機器１００の表面に直接接触しにくい。 In this embodiment, the film 3 can be fixed to the medical device 100 via the flap 5 by attaching the back surface of the flap 5 to the surface of the medical device 100 using the adhesive layer 9.

（第３実施形態）
　本発明の第３実施形態について説明する。図１１は、本実施形態の医療機器用カバーを示す平面図である。図１２は、図１１に符号Ａで示す方向から見た医療機器用カバーの側面図である。図１３は、同医療機器用カバーの作用を説明するための図である。 (Third embodiment)
A third embodiment of the present invention will be described. FIG. 11 is a plan view showing the medical device cover of the present embodiment. FIG. 12 is a side view of the medical device cover as viewed from the direction indicated by the symbol A in FIG. FIG. 13 is a view for explaining the operation of the medical device cover.
　図１１に示すように、本実施形態の医療機器用カバー１Ｂのドレープ２Ｂは、第１実施形態に開示されたフィルム３（図１参照）に代えて、第１実施形態に開示されたフィルム３とは構成が異なるフィルム１０（ドレープ本体）と、フィルム１０に設けられた折り曲げ指標１１とを備えている。また、ドレープ２Ｂは、第１実施形態と同様にフィルム１０の第一面３ａに固定された固定部４（第一固定部４ａ及び第二固定部４ｂ）を有している。さらに、本実施形態の医療機器用カバー１Ｂは、第１実施形態に開示されたフラップ５を有している。 As shown in FIG. 11, the drape 2 </ b> B of the medical device cover 1 </ b> B of the present embodiment is replaced with the film 3 disclosed in the first embodiment (see FIG. 1), and the film 3 disclosed in the first embodiment. Includes a film 10 (drape main body) having a different configuration and a folding index 11 provided on the film 10. Moreover, the drape 2B has the fixing | fixed part 4 (1st fixing | fixed part 4a and 2nd fixing | fixed part 4b) fixed to the 1st surface 3a of the film 10 similarly to 1st Embodiment. Furthermore, the medical device cover 1B of the present embodiment has the flap 5 disclosed in the first embodiment.
　図１１及び図１２に示すように、折り曲げ指標１１は、固定部４（本実施形態では第一固定部４ａ及び第二固定部４ｂ）とフラップ５との間に配されている。折り曲げ指標１１は、第一固定部４ａとフラップ５との間、及び第二固定部４ｂとフラップ５との間を横切る直線状をなしてフィルム１０に形成された折り曲げ痕１２を有している。折り曲げ痕１２は、フィルム１０の第一面３ａ側が凸となり、フィルム１０の第二面３ｂ側が凹となる形状を有している。固定部４とフラップ５とを結ぶ直線方向ｄ４において、折り曲げ指標１１からフラップ５までの距離Ｌ２は、折り曲げ指標１１から固定部４までの距離Ｌ１よりも短い。 As shown in FIGS. 11 and 12, the bending index 11 is disposed between the fixing portion 4 (the first fixing portion 4a and the second fixing portion 4b in the present embodiment) and the flap 5. The fold index 11 has a fold mark 12 formed on the film 10 in a straight line crossing between the first fixed portion 4a and the flap 5 and between the second fixed portion 4b and the flap 5. . The bending mark 12 has a shape in which the first surface 3a side of the film 10 is convex and the second surface 3b side of the film 10 is concave. In the linear direction d4 connecting the fixed portion 4 and the flap 5, the distance L2 from the folding index 11 to the flap 5 is shorter than the distance L1 from the bending index 11 to the fixed portion 4.
　本実施形態の医療機器用カバー１Ｂは、第１実施形態と同様に医療機器１００に取り付けられる（図５参照）。医療機器１００から本実施形態の医療機器用カバー１Ｂを取り外す場合には、作業者は第１実施形態と同様に把持部（山折り部７）を把持し、折り曲げ指標１１の位置においてフィルム１０がＵ字状に折り曲げられるようにフラップ５を移動させる（図７参照）。図１３に示すように、折り曲げ指標１１の位置においてフィルム１０がＵ字状となるようにフィルム１０が曲げられている状態において折り曲げ指標１１が延びる方向に沿って見ると、固定部４と折り曲げ指標１１との間にフラップ５が位置している。このため、フラップ５近傍における第二面３ｂは、固定部４近傍の第二面３ｂに接触することとなり、医療機器１００には接触しない。 The medical device cover 1B of this embodiment is attached to the medical device 100 as in the first embodiment (see FIG. 5). When removing the medical device cover 1B of the present embodiment from the medical device 100, the operator grips the grip portion (mountain fold portion 7) as in the first embodiment, and the film 10 is positioned at the position of the folding index 11. The flap 5 is moved so as to be bent in a U shape (see FIG. 7). As shown in FIG. 13, when the film 10 is bent so that the film 10 is U-shaped at the position of the bending index 11, when viewed along the direction in which the bending index 11 extends, the fixing portion 4 and the bending index 11 and the flap 5 are located. For this reason, the second surface 3 b in the vicinity of the flap 5 comes into contact with the second surface 3 b in the vicinity of the fixed portion 4 and does not come into contact with the medical device 100.
　このように、本実施形態の医療機器用カバー１Ｂによれば、医療機器１００に対してフィルム１０の第二面３ｂが接触しない状態でフィルム１０を折り曲げるための折り曲げ場所の目安として、折り曲げ指標１１を使用することができる。その結果、本実施形態の医療機器用カバー１Ｂによれば、使用後のドレープ２Ｂの取り外し作業に起因する医療機器１００の汚染が生じにくい。 As described above, according to the medical device cover 1B of the present embodiment, the folding index 11 is used as a standard for folding the film 10 in a state where the second surface 3b of the film 10 is not in contact with the medical device 100. Can be used. As a result, according to the medical device cover 1B of the present embodiment, the medical device 100 is hardly contaminated due to the removal work of the drape 2B after use.
　また、折り曲げ指標１１となる折り曲げ痕１２は、本実施形態の医療機器用カバー１Ｂを滅菌バッグに収納するために医療機器用カバー１Ｂを畳む工程で容易に形成可能である。また、折り曲げ痕１２がフィルム１０に形成されていることによって、フィルム１０が折り曲げ指標１１に沿って折れ曲がりやすくなっている。その結果、フィルム１０を整ったＵ字状に容易に畳むことができる。 Further, the folding mark 12 that becomes the folding index 11 can be easily formed in the process of folding the medical device cover 1B in order to store the medical device cover 1B of the present embodiment in the sterilization bag. Further, since the folding marks 12 are formed on the film 10, the film 10 is easily bent along the folding index 11. As a result, the film 10 can be easily folded into a well-shaped U shape.

　図２１及び図２２に示すように、本実施形態のドレープ２２は、開口部２４及び底部２５を有する袋状のフィルム２３と、フィルム２３の開口部２４に固定されたフラップ５とを有している。本実施形態におけるフラップ５は、開口部２４に固定されている点以外は第１実施形態に開示されたフラップ５と同様の構成を有している。 As shown in FIGS. 21 and 22, the drape 22 of the present embodiment includes a bag-like film 23 having an opening 24 and a bottom 25, and a flap 5 fixed to the opening 24 of the film 23. Yes. The flap 5 in the present embodiment has the same configuration as the flap 5 disclosed in the first embodiment except that the flap 5 is fixed to the opening 24.
　本実施形態のフィルム２３は、底部２５の内面に固定部４を有する。なお、フィルム２３の底部２５に固定部４が設けられていなくてもよい。 The film 23 of the present embodiment has a fixed portion 4 on the inner surface of the bottom portion 25. Note that the fixing portion 4 may not be provided on the bottom portion 25 of the film 23.
　本実施形態では、底部２５の内面が医療機器の表面に接するように開口部２４を下にしてフィルム２３が医療機器に被せられることによって、医療機器にフィルム２３が固定される（図２１参照）。
　本実施形態の医療機器用カバー１Ｈを医療機器から取り外す場合には、作業者がフラップ５の山折り部７（把持部）を把持して、図２２に示すようにフラップ５を上に持ち上げる。フラップ５が上昇するとフィルム２３の開口部２４が上に持ちあがるが、フィルム２３の底部２５が固定部４によって医療機器１００の表面に固定されているので、フィルム２３の底部の位置は変わらない。このため、作業者がフラップ５を持ち上げることにより、医療機器１００からドレープ２２が取り外される過程で、袋状のフィルム２３の内外面が反転する。すなわち、医療機器１００の使用時におけるフィルム２３の外面が医療機器１００の表面に触れることなく医療機器１００からドレープ２２が取り外される。 In the present embodiment, the film 23 is fixed to the medical device by covering the medical device with the opening 24 facing down so that the inner surface of the bottom 25 is in contact with the surface of the medical device (see FIG. 21). .
When removing the medical device cover 1H of the present embodiment from the medical device, the operator grasps the mountain fold 7 (gripping portion) of the flap 5 and lifts the flap 5 upward as shown in FIG. When the flap 5 is raised, the opening 24 of the film 23 is lifted up. However, since the bottom 25 of the film 23 is fixed to the surface of the medical device 100 by the fixing unit 4, the position of the bottom of the film 23 does not change. For this reason, when the operator lifts the flap 5, the inner and outer surfaces of the bag-like film 23 are reversed in the process of removing the drape 22 from the medical device 100. That is, the drape 22 is removed from the medical device 100 without the outer surface of the film 23 touching the surface of the medical device 100 when the medical device 100 is used.
　本実施形態では、医療機器用カバー１Ｈのフィルム２３において、汚染源に接触し得る面（医療機器１００へ取り付けられた状態における袋状のフィルム２３の外側の面２３ｂ）は、医療機器１００からの取り外し後には、袋状のフィルム２３の内面となるように反転している。このため、医療機器１００から医療機器用カバー１Ｈを取り外した後には、汚染源は袋内に封じ込められている。
　その結果、本実施形態の医療機器用カバー１Ｈによれば、使用後のドレープ２２の取り外し作業に起因する医療機器１００の汚染が生じにくい。 In the present embodiment, the surface of the film 23 of the medical device cover 1H that can come into contact with the contamination source (the outer surface 23b of the bag-like film 23 in a state of being attached to the medical device 100) is removed from the medical device 100. Later, it is inverted so as to be the inner surface of the bag-like film 23. For this reason, after removing the medical device cover 1H from the medical device 100, the contamination source is sealed in the bag.
As a result, according to the medical device cover 1H of the present embodiment, the medical device 100 is hardly contaminated due to the removal operation of the drape 22 after use.
