　本願は、２０２０年６月１日に、日本に出願された特願２０２０－０９５４２２号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to an intubation tube set.
The present application claims priority based on Japanese Patent Application No. 2020-095422 filed in Japan on June 1, 2020, the contents of which are incorporated herein by reference.
　従来から、膨張可能なカフを有する気管チューブと、カフを膨張させる可撓性膨張線とを備える気管用チューブアセンブリが知られている（例えば特許文献１参照）。特許文献１の図１に記載された技術では、使用前の気管用チューブアセンブリが、シート状の気体透過性紙とシート状の可撓性プラスチックとによって構成されたパッケージ（包装袋）に収容されている。
　ところで、特許文献１の図１に記載された技術では、パッケージを構成するシート状の気体透過性紙とシート状の可撓性プラスチックとが、縁部においてシールされている。そのため、気管用チューブアセンブリの使用者は、気管用チューブアセンブリをパッケージから取り出さなければ、潤滑剤をカフに塗布することができない。 Conventionally, a tracheal tube assembly having an inflatable cuff and a flexible expansion line for inflating the cuff has been known (see, for example, Patent Document 1). In the technique described in FIG. 1 of Patent Document 1, the tracheal tube assembly before use is housed in a package (packaging bag) composed of a sheet-shaped gas permeable paper and a sheet-shaped flexible plastic. ing.
By the way, in the technique described in FIG. 1 of Patent Document 1, the sheet-shaped gas permeable paper constituting the package and the sheet-shaped flexible plastic are sealed at the edge portion. Therefore, the user of the tracheal tube assembly cannot apply the lubricant to the cuff without removing the tracheal tube assembly from the package.
　また、従来から、気管挿管に用いられる気管挿管用部材と、気管挿管用部材を収容する収納バッグとを備える気管挿管セットが知られている（例えば特許文献２参照）。特許文献２の図１、図３および図４に記載された技術では、使用前の気管挿管用部材が、収納バッグに収容されている。
　特許文献２の図１、図３および図４に記載された技術においても、収納バッグの縁部が、溶着、接着等の接続手段によって密着させられている。そのため、気管挿管用部材の使用者は、気管挿管用部材を収納バッグから取り出さなければ、潤滑剤をカフに塗布することができない。 Further, conventionally, a tracheal intubation set including a tracheal intubation member used for tracheal intubation and a storage bag for accommodating the tracheal intubation member has been known (see, for example, Patent Document 2). In the technique described in FIGS. 1, 3 and 4 of Patent Document 2, the tracheal intubation member before use is housed in a storage bag.
Also in the techniques described in FIGS. 1, 3 and 4 of Patent Document 2, the edges of the storage bag are brought into close contact with each other by connecting means such as welding and adhesion. Therefore, the user of the tracheal intubation member cannot apply the lubricant to the cuff unless the tracheal intubation member is taken out from the storage bag.
　気管用チューブアセンブリをパッケージから取り出した後、あるいは、気管挿管用部材を収納バッグから取り出した後に潤滑剤をカフに塗布する作業は、例えば狭い場所で気管挿管を迅速に行うことが要求される救急救命士にとって、非常に煩雑な作業である。従って、気管用チューブアセンブリのパッケージ、あるいは、気管挿管用部材の収納バッグの改善が望まれている。 The task of applying a lubricant to the cuff after removing the tracheal tube assembly from the package or after removing the tracheal intubation member from the storage bag is an emergency that requires rapid tracheal intubation, for example, in a narrow space. It is a very complicated task for paramedics. Therefore, it is desired to improve the package of the tracheal tube assembly or the storage bag of the tracheal intubation member.

FIG. 1 is a diagram showing an example of the configuration of the intubation tube set 1 of the first embodiment. In detail, FIG. 1 is a diagram showing a body insertion tube set 1 in a state where the body insertion tube 11 is housed in a packaging bag 14. FIG. 2 is a diagram showing an example of an intubation tube 11 and the like before being housed in the packaging bag 14. In detail, FIG. 2A shows the internal insertion tube 11 before being stored in the packaging bag 14, and FIG. 2B shows the lubricant storage bag 12 before being stored in the packaging bag 14. ing.
In the example shown in FIGS. 1 and 2, the internal insertion tube set 1 includes an internal insertion tube 11, a lubricant storage bag 12, a lubricant 13, and a packaging bag 14.
The internal insertion tube 11 is a tube that is inserted into an organ such as the trachea, esophagus, or large intestine of a human or animal. The internal intubation tube 11 includes a tube body 11A and a portion to be coated (for example, a cuff 11B) to which the lubricant 13 is applied. The tube body 11A is a tubular portion, for example, a portion that ventilates the trachea when the internal insertion tube 11 is used for tracheal intubation.
The tube body 11A includes a tip end portion 11A1 and a base end portion 11A2. The tip portion 11A1 is a portion inserted into an organ such as the trachea, esophagus, or large intestine of a human or animal when the internal insertion tube 11 is used. The proximal end 11A2 is a portion that is placed (remained) outside the body of a human or animal when the intubation 11 is used without being inserted into an organ such as the trachea, esophagus, or large intestine.
The cuff 11B is a portion that seals between the outer peripheral surface of the tube body 11A and the inner wall surface of the organ. The cuff 11B is configured to be inflatable. To facilitate understanding of the cuff 11B, FIG. 2A shows the cuff 11B in an inflated state. Actually, as shown in FIG. 1, the intubation tube 11 is housed in the packaging bag 14 in a state where the cuff 11B is not inflated.
The lubricant storage bag 12 is a bag that stores the lubricant 13. Lubricant 13 is any known medical lubricant, such as KY® jelly.
The packaging bag 14 is a bag for packaging the internal intubation tube 11 and the like in a sterilized state.
　図１に示す体内挿入管セット１では、潤滑剤収容袋１２（図２（Ｂ）参照）が、包装袋１４内に収容されている。また、潤滑剤収容袋１２が、例えば溶着などのような公知の任意の手法によって、包装袋１４に固定されている。詳細には、図１に示すように、潤滑剤１３を収容する潤滑剤収容袋１２が、体内挿入管１１のカフ１１Ｂに隣接して配置されている。また、潤滑剤収容袋１２の強度が、包装袋１４の強度よりも低い値に設定されている。
　図１に示す例では、体内挿入管セット１の使用時に、例えば救急救命士などの体内挿入管セット１の使用者によって、潤滑剤収容袋１２が加圧される。その結果、潤滑剤収容袋１２が破れ、潤滑剤収容袋１２に収容されていた潤滑剤１３が、体内挿入管１１のカフ１１Ｂ（被塗布部）に塗布される。
　一方、潤滑剤収容袋１２が加圧されても、体内挿入管１１および潤滑剤収容袋１２を収容している包装袋１４は破れない。その結果、包装袋１４の内側において潤滑剤１３がカフ１１Ｂ（被塗布部）に塗布された状態になる。
　そのため、図１に示す例では、例えば救急救命士などの体内挿入管セット１の使用者は、潤滑剤１３がカフ１１Ｂ（被塗布部）に塗布された状態で体内挿入管１１を包装袋１４から取り出すことができる。 In the intubation tube set 1 shown in FIG. 1, the lubricant storage bag 12 (see FIG. 2B) is housed in the packaging bag 14. Further, the lubricant storage bag 12 is fixed to the packaging bag 14 by any known method such as welding. Specifically, as shown in FIG. 1, a lubricant accommodating bag 12 accommodating the lubricant 13 is arranged adjacent to the cuff 11B of the intubation tube 11. Further, the strength of the lubricant accommodating bag 12 is set to a value lower than the strength of the packaging bag 14.
In the example shown in FIG. 1, when the internal insertion tube set 1 is used, the lubricant storage bag 12 is pressurized by a user of the internal insertion tube set 1, such as an emergency medical technician. As a result, the lubricant storage bag 12 is torn, and the lubricant 13 stored in the lubricant storage bag 12 is applied to the cuff 11B (coated portion) of the internal insertion tube 11.
On the other hand, even if the lubricant accommodating bag 12 is pressurized, the packaging bag 14 accommodating the internal insertion tube 11 and the lubricant accommodating bag 12 is not torn. As a result, the lubricant 13 is applied to the cuff 11B (coated portion) inside the packaging bag 14.
Therefore, in the example shown in FIG. 1, a user of the internal insertion tube set 1 such as an emergency medical technician puts the internal insertion tube 11 in a packaging bag 14 with the lubricant 13 applied to the cuff 11B (applied portion). Can be taken out from.
　換言すれば、図１に示す体内挿入管セット１は、体内挿入管１１が包装袋１４内に収容されている状態で潤滑剤１３をカフ１１Ｂ（被塗布部）に供給する潤滑剤供給部１Ａを備えている。潤滑剤供給部１Ａには、包装袋１４内に収容されている潤滑剤収容袋１２が含まれる。 In other words, in the internal insertion tube set 1 shown in FIG. 1, the lubricant supply unit 1A that supplies the lubricant 13 to the cuff 11B (coated portion) while the internal insertion tube 11 is housed in the packaging bag 14. It is equipped with. The lubricant supply unit 1A includes a lubricant storage bag 12 housed in the packaging bag 14.
　図１および図２に示す例では、体内挿入管１１がカフ１１Ｂを備えており、潤滑剤１３がカフ１１Ｂに塗布される（つまり、カフ１１Ｂが、「被塗布部」である）。
　他の例（例えば体内挿入管１１が経鼻式の体内挿入管である例）では、体内挿入管１１がカフ１１Ｂを備えていなくてもよい。この例では、潤滑剤１３が、チューブ本体１１Ａのうちの先端部１１Ａ１から少し離れた部分（被塗布部）に塗布される。つまり、チューブ本体１１Ａのうちの、潤滑剤１３がチューブ本体１１Ａの先端部１１Ａ１の穴を塞ぐおそれがない部分が、被塗布部として機能する。 In the example shown in FIGS. 1 and 2, the intubation tube 11 comprises a cuff 11B and the lubricant 13 is applied to the cuff 11B (that is, the cuff 11B is the "applied portion").
In other examples (eg, where the intubation 11 is a nasal intubation), the intubation 11 may not include the cuff 11B. In this example, the lubricant 13 is applied to a portion (applied portion) of the tube body 11A slightly distant from the tip portion 11A1. That is, the portion of the tube body 11A where the lubricant 13 is unlikely to close the hole in the tip portion 11A1 of the tube body 11A functions as the coated portion.
　図１および図２に示す例では、スタイレット（図示せず）が包装袋１４に収容されていない。
　他の例では、スタイレット（図示せず）が包装袋１４に収容されていてもよい。スタイレットが包装袋１４に収容される第１例では、スタイレットが、体内挿入管１１に挿入された状態で、包装袋１４に収容される。
　スタイレットが包装袋１４に収容される第２例では、スタイレットが、体内挿入管１１に挿入されていない状態で、包装袋１４に収容される。この例では、潤滑剤収容袋１２が破れ、潤滑剤収容袋１２に収容されていた潤滑剤１３が、体内挿入管１１のカフ１１Ｂ（被塗布部）に塗布される時に、潤滑剤収容袋１２に収容されていた潤滑剤１３が、スタイレットにも塗布される。すなわち、潤滑剤供給部１Ａは、体内挿入管１１とスタイレットとが包装袋１４内に収容されている状態で、潤滑剤１３をカフ１１Ｂ（被塗布部）とスタイレットとに供給する。
　この例では、体内挿入管１１が、包装袋１４の一方の端部（図１の右側の端部）から取り出され、スタイレットは、包装袋１４の他方の端部（図１の左側の端部、つまり、潤滑剤収容袋１２に近い側の端部）から取り出される。そのため、スタイレットの全体に潤滑剤１３を塗布することができる。好ましくは、包装袋１４に収容されるスタイレットとして、例えばＦＥＰ（テトラフルオロエチレン・ヘキサフルオロプロピレン共重合体）などの低摩擦性材料によって形成されたスタイレットが用いられる。 In the examples shown in FIGS. 1 and 2, the stylet (not shown) is not housed in the packaging bag 14.
In another example, the stylet (not shown) may be housed in the packaging bag 14. In the first example in which the stylet is housed in the packaging bag 14, the stylet is housed in the packaging bag 14 in a state of being inserted into the internal insertion tube 11.
In the second example in which the stylet is housed in the packaging bag 14, the stylet is housed in the packaging bag 14 without being inserted into the intubation tube 11. In this example, when the lubricant storage bag 12 is torn and the lubricant 13 stored in the lubricant storage bag 12 is applied to the cuff 11B (coated portion) of the internal insertion tube 11, the lubricant storage bag 12 is applied. The lubricant 13 contained in the stylet is also applied to the stylet. That is, the lubricant supply unit 1A supplies the lubricant 13 to the cuff 11B (coated portion) and the stylet while the intubation tube 11 and the stylet are housed in the packaging bag 14.
In this example, the intubation tube 11 is removed from one end of the packaging bag 14 (the right end of FIG. 1) and the stylet is the other end of the packaging bag 14 (the left end of FIG. 1). It is taken out from the portion, that is, the end portion on the side closer to the lubricant accommodating bag 12. Therefore, the lubricant 13 can be applied to the entire stylet. Preferably, as the stylet housed in the packaging bag 14, a stylet made of a low friction material such as FEP (tetrafluoroethylene / hexafluoropropylene copolymer) is used.
［第２実施形態］
　以下、本発明の体内挿入管セットの第２実施形態について説明する。
　第２実施形態の体内挿入管セット１は、後述する点を除き、上述した第１実施形態の体内挿入管セット１と同様に構成されている。従って、第２実施形態の体内挿入管セット１によれば、後述する点を除き、上述した第１実施形態の体内挿入管セット１と同様の効果を奏することができる。 [Second Embodiment]
Hereinafter, a second embodiment of the intubation tube set of the present invention will be described.
The intubation tube set 1 of the second embodiment is configured in the same manner as the intubation tube set 1 of the first embodiment described above, except for the points described later. Therefore, according to the intubation tube set 1 of the second embodiment, the same effect as that of the intubation tube set 1 of the first embodiment described above can be obtained except for the points described later.
　図３は第２実施形態の体内挿入管セット１の構成の一例などを示す図である。詳細には、図３（Ａ）は第２実施形態の体内挿入管セット１の構成の一例を示しており、図３（Ｂ）は図３（Ａ）中の弁部１４Ｂを拡大して示した部品図である。
　上述したように、図１および図２に示す例では、体内挿入管セット１が、体内挿入管１１と、潤滑剤収容袋１２と、潤滑剤１３と、包装袋１４とを備えている。一方、図３に示す例では、体内挿入管セット１が、体内挿入管１１と、包装袋１４とを備えており、潤滑剤収容袋１２と、潤滑剤１３とを備えていない。
　図３に示す例では、図１および図２に示す例と同様に、包装袋１４が、滅菌された状態で体内挿入管１１を包装する袋である。
　図３に示す例では、包装袋１４が、本体部１４Ａと、弁部１４Ｂとを備えている。本体部１４Ａは、体内挿入管１１を包装する袋状の部分である。弁部１４Ｂは、潤滑剤１３を供給する潤滑剤供給針（図示せず）を抜き差し可能に構成されている。弁部１４Ｂは、例えば溶着などの公知の任意の手法によって、包装袋１４の本体部１４Ａに固定されている。 FIG. 3 is a diagram showing an example of the configuration of the intubation tube set 1 of the second embodiment. In detail, FIG. 3 (A) shows an example of the configuration of the internal insertion tube set 1 of the second embodiment, and FIG. 3 (B) shows an enlarged valve portion 14B in FIG. 3 (A). It is a parts drawing.
As described above, in the example shown in FIGS. 1 and 2, the internal insertion tube set 1 includes an internal insertion tube 11, a lubricant storage bag 12, a lubricant 13, and a packaging bag 14. On the other hand, in the example shown in FIG. 3, the internal insertion tube set 1 includes the internal insertion tube 11 and the packaging bag 14, but does not include the lubricant storage bag 12 and the lubricant 13.
In the example shown in FIG. 3, the packaging bag 14 is a bag for packaging the internal insertion tube 11 in a sterilized state, as in the examples shown in FIGS. 1 and 2.
In the example shown in FIG. 3, the packaging bag 14 includes a main body portion 14A and a valve portion 14B. The main body portion 14A is a bag-shaped portion for wrapping the intubation tube 11. The valve portion 14B is configured so that a lubricant supply needle (not shown) for supplying the lubricant 13 can be inserted and removed. The valve portion 14B is fixed to the main body portion 14A of the packaging bag 14 by any known method such as welding.
　図３に示す体内挿入管セット１では、包装袋１４の弁部１４Ｂが、体内挿入管１１のカフ１１Ｂ（被塗布部）に隣接して配置されている。
　図３に示す例では、体内挿入管セット１の使用時に、例えば救急救命士などの体内挿入管セット１の使用者によって、潤滑剤供給針が、包装袋１４の弁部１４Ｂに差し込まれる。更に、潤滑剤１３が、潤滑剤供給針から包装袋１４の本体部１４Ａの内部に供給され、体内挿入管１１のカフ１１Ｂ（被塗布部）に塗布される。
　一方、潤滑剤１３が、潤滑剤供給針から包装袋１４の本体部１４Ａの内部に供給されても、体内挿入管１１を収容している包装袋１４は破れない。また、包装袋１４の本体部１４Ａの内部に供給された潤滑剤１３が、弁部１４Ｂを介して包装袋１４の外側に流出することもない。その結果、包装袋１４の内側において潤滑剤１３がカフ１１Ｂ（被塗布部）に塗布された状態になる。
