Description

本発明は、チューブが接続された状態で、液体収容体の口部に装着されるコネクタに関する。   The present invention relates to a connector attached to a mouth of a liquid container in a state where a tube is connected.

従来、食事等を口から摂取できない場合の療法として、患者の腹部に形成された胃ろうにチューブを挿入し、このチューブを介して、ボトルやバッグ等の液体収容体に収容された栄養剤、流動食、薬剤等といった経腸栄養剤を患者に投与する経腸栄養療法が知られている。   Conventionally, as a therapy when a meal or the like cannot be taken from the mouth, a tube is inserted into a gastric fistula formed in the abdomen of the patient, and through this tube, a nutrient contained in a liquid container such as a bottle or a bag, Enteral nutrition therapy in which enteral nutrients such as liquid foods and drugs are administered to patients is known.

また、従来、患者の静脈に輸液ライン用のチューブを挿入し、このチューブを介して、ボトルやバッグ等の液体収容体に収容されたブドウ糖等の栄養成分や薬剤成分を含む輸液を患者に投与する静脈栄養療法も知られている。   Conventionally, a tube for an infusion line is inserted into a patient's vein, and an infusion containing a nutrient component such as glucose or a drug component contained in a liquid container such as a bottle or bag is administered to the patient via this tube. Parenteral nutrition therapy is also known.

これらのような療法に用いられている液体収容体は、口部にキャップが装着された状態で流通している。液体収容体にチューブを接続する際には、キャップを取り外し、その代わりに、チューブが接続されたコネクタを液体収容体の口部に装着する。コネクタは、液体収容体の口部の雄ねじと螺合する雌ねじが内周面に形成されると共に、チューブが接続される接続部を備えている（例えば、特許文献１，２参照）。   Liquid containers used for such therapy are distributed with a cap attached to the mouth. When connecting the tube to the liquid container, the cap is removed, and instead, the connector to which the tube is connected is attached to the mouth of the liquid container. The connector includes a connecting portion to which a tube is connected while an internal thread is formed on the inner peripheral surface of the liquid container so as to be engaged with a male screw at the mouth of the liquid container (see, for example, Patent Documents 1 and 2).

特開平８−９８８８５号公報Japanese Patent Laid-Open No. 8-98885 特開２００９−１３１５９５号公報JP 2009-131595 A

しかし、チューブが接続されたコネクタを液体収容体の口部に装着する際、液体収容体の口部の雄ねじとコネクタの雌ねじとを螺合するために、液体収容体に対してコネクタを回転させるので、コネクタに接続されたチューブが捩れるおそれがある。チューブが捩れると、使い勝手が悪化する、チューブが外れ易くなる、患者に余分な力が作用するなどの問題が生じる。   However, when the connector to which the tube is connected is attached to the mouth of the liquid container, the connector is rotated with respect to the liquid container in order to screw the male screw of the mouth of the liquid container and the female screw of the connector. Therefore, the tube connected to the connector may be twisted. When the tube is twisted, there are problems such as deterioration in usability, the tube being easily detached, and excessive force acting on the patient.

本発明は以上の点に鑑みてなされたものであり、液体収容体の口部に装着する際に、接続されているチューブに捩れが生じないコネクタを提供することを目的とする。   The present invention has been made in view of the above points, and an object of the present invention is to provide a connector in which twisting does not occur in a connected tube when it is attached to the mouth of a liquid container.

本発明のコネクタは、チューブが接続された状態で、液体収容体の外周面に雄ねじが形成された口部に装着されるコネクタであって、前記雄ねじと螺合する雌ねじを内周面に有するキャップ体と、前記チューブが接続されるチューブ接続部を有し、前記キャップ体に対して回転自在に設けられたチューブ接続体と、前記キャップ体と前記チューブ接続体との間に設けられ、これらの間から液体が漏れ出ることを防止する漏れ防止体と、前記キャップ体又は前記チューブ接続体に設けられ、前記口部の内周面と嵌合する嵌合部とを備えることを特徴とする。   The connector of the present invention is a connector that is attached to a mouth portion in which a male screw is formed on the outer peripheral surface of the liquid container in a state where the tube is connected, and has a female screw that is screwed with the male screw on the inner peripheral surface. A cap body, a tube connection portion to which the tube is connected, a tube connection body rotatably provided with respect to the cap body, and provided between the cap body and the tube connection body, A leak preventing body that prevents liquid from leaking out from the gap, and a fitting portion that is provided on the cap body or the tube connecting body and is fitted to the inner peripheral surface of the mouth portion. .

本発明によれば、液体収容体の口部にコネクタを装着する際、即ち、液体収容体の口部の雄ねじにキャップ体の雌ねじを螺合させるように、キャップ体を回転させながら液体収容体に向けて押し込む際、チューブ接続体はキャップ体に対して回転自在であるので、チューブ接続体に接続されたチューブには捩れが生じない。   According to the present invention, when the connector is attached to the mouth of the liquid container, that is, the liquid container while rotating the cap body so that the female screw of the cap body is screwed into the male screw of the mouth of the liquid container. Since the tube connection body is rotatable with respect to the cap body when being pushed toward the tube, the tube connected to the tube connection body is not twisted.

また、液体収容体の口部にコネクタが装着された状態では、口部の雄ねじとキャップ体の雌ねじとが螺合しているので、これらの間が密閉され、その隙間から液体が漏れ出ることはない。さらに、前記状態では、嵌合部が口部の内周面と嵌合するので、これらの間が密閉され、その隙間から液体が漏れ出ることはない。   Further, in the state where the connector is attached to the mouth portion of the liquid container, the male screw of the mouth portion and the female screw of the cap body are screwed together, so that the space between them is sealed and the liquid leaks from the gap. There is no. Furthermore, in the said state, since a fitting part fits with the internal peripheral surface of an opening | mouth part, between these is sealed and a liquid does not leak from the clearance gap.

このように、液体収容体の口部にコネクタを装着することによって、コネクタと液体収容体との隙間から液体が漏れ出ることが二重に防止されている。さらに、漏れ防止体によって、常時、キャップ体とチューブ接続体との隙間から液体が漏れ出ることはない。   Thus, by mounting the connector on the mouth of the liquid container, the liquid is prevented from leaking out from the gap between the connector and the liquid container. Furthermore, the leakage preventing body does not always allow liquid to leak from the gap between the cap body and the tube connecting body.

また、本発明のコネクタにおいて、前記キャップ体又は前記チューブ接続体に設けられ、口部に設けられた膜を穿通可能な穿通部を備えることが好ましい。   Moreover, the connector of this invention WHEREIN: It is preferable to provide the penetration part which can be penetrated the film | membrane provided in the said cap body or the said tube connection body, and was provided in the opening | mouth part.

この場合、液体収容体の口部にコネクタを装着する際に、膜が穿通部で穿通されるので、液体収容体の内部の液体が漏れ出るおそれがない。   In this case, when the connector is attached to the mouth portion of the liquid container, the membrane is pierced by the piercing portion, so there is no possibility that the liquid inside the liquid container leaks.

また、本発明のコネクタにおいて、前記嵌合部は、前記チューブ接続体に設けられることが好ましい。   Moreover, the connector of this invention WHEREIN: It is preferable that the said fitting part is provided in the said tube connection body.

この場合、液体収容体の口部の内周面と嵌合部が嵌合した後、雄ねじにキャップ体の雌ねじを螺合させるように、キャップ体を回転させながら液体収容体に向けて押し込む際、口部に対してチューブ接続体が回転し難くなり、チューブにより捩れが生じ難い。   In this case, after the inner peripheral surface of the mouth portion of the liquid container and the fitting portion are fitted, the cap body is pushed into the liquid container while being rotated so that the female screw of the cap body is screwed into the male screw. The tube connection body is difficult to rotate with respect to the mouth, and the tube is less likely to be twisted.

本発明の実施形態に係るコネクタ１０について説明する。   A connector 10 according to an embodiment of the present invention will be described.

図１及び図２に示すように、コネクタ１０は、液体収容体２０にチューブ３０を接続するための接続部材である。コネクタ１０は、液体収容体２０の口部２１に装着され、可撓性のチューブ３０が接続可能に構成されている。   As shown in FIGS. 1 and 2, the connector 10 is a connection member for connecting a tube 30 to the liquid container 20. The connector 10 is attached to the mouth portion 21 of the liquid container 20 so that a flexible tube 30 can be connected.

液体収容体２０は、例えば、経腸栄養剤や輸液などの液体が収容されたバッグやボトル等の容器である。液体収容体２０の口部２１は、液体収容体２０の上部や下部などに設けられており、外周面に雄ねじ２２が形成されている。チューブ３０は、経腸栄養療法に用いられる医療用チューブや静脈栄養療法に用いられる輸液ライン用のチューブである。   The liquid container 20 is a container such as a bag or a bottle in which a liquid such as an enteral nutrient or an infusion is stored. The mouth portion 21 of the liquid container 20 is provided at an upper part or a lower part of the liquid container 20, and a male screw 22 is formed on the outer peripheral surface. The tube 30 is a medical tube used for enteral nutrition therapy or an infusion line tube used for parenteral nutrition therapy.

コネクタ１０は、液体収容体２０の口部２１に装着されるキャップ体１１と、チューブ３０が接続されるチューブ接続体１２とを備えており、キャップ体１１とチューブ接続体１２とは回転自在に構成されている。   The connector 10 includes a cap body 11 attached to the mouth portion 21 of the liquid container 20 and a tube connecting body 12 to which a tube 30 is connected. The cap body 11 and the tube connecting body 12 are rotatable. It is configured.

キャップ体１１は、全体として概略短円筒状であり、その内周面に、液体収容体２０の口部２１の雄ねじ２２と螺合する雌ねじ１１ａが形成されている。そして、キャップ体１１には、口部２１に装着される側と反対側の円筒状の開放端を覆うように蓋部１１ｂが形成されている。この蓋部１１ｂの中央には、円形の貫通孔１１ｃが形成されている。キャップ体１１は、ポリプロピレン（ＰＰ）やポリエチレン（ＰＥ）といった樹脂材料を用いて、一体成形されている。   The cap body 11 has a substantially short cylindrical shape as a whole, and an internal thread 11 a that is screwed with the external thread 22 of the mouth portion 21 of the liquid container 20 is formed on the inner peripheral surface thereof. The cap body 11 is formed with a lid portion 11b so as to cover a cylindrical open end opposite to the side attached to the mouth portion 21. A circular through hole 11c is formed in the center of the lid portion 11b. The cap body 11 is integrally formed using a resin material such as polypropylene (PP) or polyethylene (PE).

チューブ接続体１２は、キャップ体１１に形成された貫通孔１１ｃに挿通されている。具体的には、チューブ接続体１２は、貫通孔１１ｃに挿通される長円筒状の長円筒部１２ａを備え、長円筒部１２ａの外径は貫通孔１１ｃの径よりも僅かに小さくなっている。   The tube connector 12 is inserted through a through hole 11 c formed in the cap body 11. Specifically, the tube connector 12 includes a long cylindrical portion 12a inserted into the through hole 11c, and the outer diameter of the long cylindrical portion 12a is slightly smaller than the diameter of the through hole 11c. .

長円筒部１２ａには、軸方向に延びる貫通孔１２ｂが形成されると共に、貫通孔１２ｂより大径の接続穴１２ｃが形成されている。接続穴１２ｃにチューブ３０が嵌入されることにより、チューブ接続体１２にチューブ３０が接続される。接続穴１２ｃの開放端には、テーパ１２ｄが形成されており、チューブ３０を接続穴１２ｃに嵌入させ易くなっている。   The long cylindrical portion 12a is formed with a through hole 12b extending in the axial direction and a connection hole 12c having a diameter larger than that of the through hole 12b. The tube 30 is connected to the tube connector 12 by fitting the tube 30 into the connection hole 12c. A taper 12d is formed at the open end of the connection hole 12c so that the tube 30 can be easily fitted into the connection hole 12c.

チューブ接続体１２は、さらに、液体収容体２０の口部２１の内径と同等の外径を有する短円筒状の短円筒部１２ｅを備えている。長円筒部１２ａと短円筒部１２ｅとは、これらを接続するドーナツ状の連結部１２ｆと共に一体に形成されている。長円筒部１２ａと短円筒部１２ｅとの軸心は一致している。   The tube connector 12 further includes a short cylindrical portion 12 e having a short cylindrical shape having an outer diameter equivalent to the inner diameter of the mouth portion 21 of the liquid container 20. The long cylindrical portion 12a and the short cylindrical portion 12e are integrally formed with a donut-shaped connecting portion 12f that connects them. The axial centers of the long cylindrical portion 12a and the short cylindrical portion 12e coincide.

短円筒部１２ｅは、キャップ体１１の内周面と対向するように位置している。短円筒部１２ｅの外径は、口部２１の内径と同等に形成されており、短円筒部１２ｅの先端部は口部２１に嵌入可能となっている。短円筒部１２ｅの先端部は、本発明の嵌合部に相当する。   The short cylindrical portion 12 e is positioned so as to face the inner peripheral surface of the cap body 11. The outer diameter of the short cylindrical portion 12 e is formed to be equal to the inner diameter of the mouth portion 21, and the distal end portion of the short cylindrical portion 12 e can be fitted into the mouth portion 21. The tip of the short cylindrical portion 12e corresponds to the fitting portion of the present invention.

チューブ接続体１２は、ポリプロピレン（ＰＰ）やポリエチレン（ＰＥ）といった樹脂材料を用いて、一体成形されている。   The tube connector 12 is integrally formed using a resin material such as polypropylene (PP) or polyethylene (PE).

コネクタ１０は、さらに、キャップ体１１とチューブ接続体１２との隙間から液体が漏れないように、漏れ防止体１３を備えている。ここでは、漏れ防止体１３は、キャップ体１１とチューブ接続体１２との間に設けられた、ゴムや樹脂からなるリング状パッキン又はＯリングである。   The connector 10 further includes a leakage prevention body 13 so that liquid does not leak from the gap between the cap body 11 and the tube connection body 12. Here, the leak preventing body 13 is a ring-shaped packing or O-ring made of rubber or resin provided between the cap body 11 and the tube connecting body 12.

キャップ体１１の蓋部１１ｂの内側の口部２１側の端部には円周状に切欠１１ｄが形成されている。そして、この切欠１１ｄに漏れ防止体１３が収容され、キャップ体１１の貫通孔１１ｃとチューブ接続体１２の長円筒部１２ａとの隙間から液体が漏れ出ることが防止される。   A notch 11d is formed in a circumferential shape at the end of the cap body 11 on the side of the mouth portion 21 inside the lid portion 11b. And the leak prevention body 13 is accommodated in this notch 11d, and it is prevented that a liquid leaks from the clearance gap between the through-hole 11c of the cap body 11, and the long cylindrical part 12a of the tube connection body 12. FIG.

次に、コネクタ１０の液体収容体２０の口部２１への装着作業について説明する。   Next, the mounting operation of the connector 10 to the mouth portion 21 of the liquid container 20 will be described.

予め、チューブ接続体１２の接続穴１２ｃにチューブ３０を嵌入させて、チューブ接続体１２にチューブ３０を接続しておく。   The tube 30 is inserted into the connection hole 12 c of the tube connector 12 in advance, and the tube 30 is connected to the tube connector 12.

チューブ３０が接続されたコネクタ１０を、液体収容体２０の口部２１に装着する。具体的には、口部２１の雄ねじ２２に、キャップ体１１の雌ねじ１１ａを螺合させるように、キャップ体１１を回転させながら、キャップ体１１を液体収容体２０に向けて押し込む。これにより、チューブ接続体１２は、キャップ体１１の蓋部１１ｂによって、連結部１２ｆが押圧されることにより、キャップ体１１と共に液体収容体２０に向けて押し込まれる。この際、チューブ接続体１２はキャップ体１１に対して回転自在であるので、チューブ接続体１２に接続されたチューブには捩れが生じない。   The connector 10 to which the tube 30 is connected is attached to the mouth portion 21 of the liquid container 20. Specifically, the cap body 11 is pushed toward the liquid container 20 while rotating the cap body 11 so that the female thread 11a of the cap body 11 is screwed into the male thread 22 of the mouth portion 21. Thereby, the tube connection body 12 is pushed toward the liquid container 20 together with the cap body 11 when the connecting portion 12 f is pressed by the lid portion 11 b of the cap body 11. At this time, since the tube connection body 12 is rotatable with respect to the cap body 11, the tube connected to the tube connection body 12 is not twisted.

なお、口部２１に短円筒部１２ｅが嵌合した後、口部２１の雄ねじ２２にキャップ体１１の雌ねじ１１ａを螺合させるように、キャップ体１１を回転させながら液体収容体２０に向けて押し込む際、前記嵌合によって口部２１に対してチューブ接続体１２が回転し難くなり、チューブ３０に捩れがより生じ難くなる。   In addition, after the short cylindrical portion 12e is fitted to the mouth portion 21, the cap body 11 is rotated toward the liquid container 20 while rotating the cap body 11 so that the female screw 11a of the cap body 11 is screwed to the male screw 22 of the mouth portion 21. When pushing in, the tube connection body 12 becomes difficult to rotate with respect to the mouth portion 21 by the fitting, and the tube 30 is less likely to be twisted.

液体収容体２０の口部２１にコネクタ１０が装着されたとき、口部２１の雄ねじ２２とキャップ体１１の雌ねじ１１ａとが螺合しているので、これらの間が密閉され、その隙間から液体が漏れ出ることはない。   When the connector 10 is attached to the mouth portion 21 of the liquid container 20, the male screw 22 of the mouth portion 21 and the female screw 11 a of the cap body 11 are screwed together. Will not leak.

そして、チューブ接続体１２の短円筒部１２ｅの先端部は、口部２１に嵌入されているので、これらの間が密閉され、その隙間から液体が漏れ出ることはない。   And since the front-end | tip part of the short cylindrical part 12e of the tube connection body 12 is inserted by the opening | mouth part 21, between these is sealed, a liquid does not leak from the clearance gap.

このように、コネクタ１０を液体収容体２０の口部２１に装着することによって、コネクタ１０と液体収容体２０との隙間から液体が漏れ出ることは二重に防止されている。   As described above, by mounting the connector 10 to the mouth portion 21 of the liquid container 20, it is possible to prevent liquid from leaking from the gap between the connector 10 and the liquid container 20.

さらに、漏れ防止体１３によって、常時、キャップ体１１とチューブ接続体１２との隙間から液体が漏れ出ることはない。   Further, the leakage preventing body 13 does not always allow the liquid to leak from the gap between the cap body 11 and the tube connector 12.

以下、本発明の実施形態の変形例について説明する。   Hereinafter, modifications of the embodiment of the present invention will be described.

前述した実施形態では、チューブ接続体１２の短円筒部１２ｅの先端部が口部２１に嵌入される場合について説明した。図３に示すように、第１の変形例では、キャップ体１１と一体に構成された本発明の嵌合部に相当する部材が口部２１に嵌入される。   In the above-described embodiment, the case where the distal end portion of the short cylindrical portion 12e of the tube connecting body 12 is fitted into the mouth portion 21 has been described. As shown in FIG. 3, in the first modification, a member corresponding to the fitting portion of the present invention configured integrally with the cap body 11 is inserted into the mouth portion 21.

キャップ体１１の蓋部１１ｂには、口部２１側に延びる円筒形の突壁部１１ｅが形成されている。この突壁部１１ｅの外径は、液体収容体２０の口部２１の内径と同等である。この突壁部１１ｅが本発明の嵌合部に相当する。   A cylindrical protruding wall portion 11 e extending toward the mouth portion 21 is formed on the lid portion 11 b of the cap body 11. The outer diameter of the protruding wall portion 11 e is equal to the inner diameter of the mouth portion 21 of the liquid container 20. This protruding wall portion 11e corresponds to the fitting portion of the present invention.

なお、この場合、口部２１に突壁部１１ｅが嵌合した後、口部２１の雄ねじ２２にキャップ体１１の雌ねじ１１ａを螺合させるように、キャップ体１１を回転させながら液体収容体２０に向けて押し込む際、前記嵌合によって口部２１に対してキャップ体１１を回転し難くなる。   In this case, after the protruding wall portion 11e is fitted to the mouth portion 21, the liquid container 20 is rotated while the cap body 11 is rotated so that the female screw 11a of the cap body 11 is screwed to the male screw 22 of the mouth portion 21. When it pushes in toward, it becomes difficult to rotate the cap body 11 with respect to the opening | mouth part 21 by the said fitting.

さらに、キャップ体１１に切欠１１ｄが形成されていない。チューブ接続体１２は、短円筒部１２ｅ及び連結部１２ｆを備えておらず、その代わりに、長円筒部１２ａの口部２１側の端部から半径方向外側に向かって拡がるドーナツ状の拡径部１２ｇを備えている。   Further, the cap body 11 is not formed with a notch 11d. The tube connecting body 12 does not include the short cylindrical portion 12e and the connecting portion 12f, but instead, a donut-shaped enlarged diameter portion that expands radially outward from the end on the mouth portion 21 side of the long cylindrical portion 12a. 12g.

そして、漏れ防止体１３は、キャップ体１１の蓋部１１ｂとチューブ接続体１２の拡径部１２ｇとの間に配置される。   And the leak prevention body 13 is arrange | positioned between the cover part 11b of the cap body 11, and the enlarged diameter part 12g of the tube connection body 12. FIG.

また、図４に示すように、チューブ接続体１２が、長円筒部１２ａの中間部に半径方向外側に向かって拡がるドーナツ状の拡径部１２ｈを備えていてもよい。この場合、漏れ防止体１３は、キャップ体１１の蓋部１１ｂとチューブ接続体１２の拡径部１２ｈとの間に配置され、キャップ体１１の外部に位置している。   Moreover, as shown in FIG. 4, the tube connector 12 may include a donut-shaped enlarged diameter portion 12h that expands outward in the radial direction at the middle portion of the long cylindrical portion 12a. In this case, the leakage prevention body 13 is disposed between the lid portion 11 b of the cap body 11 and the diameter-enlarged portion 12 h of the tube connection body 12 and is located outside the cap body 11.

ただし、この場合、チューブ接続体１２がキャップ体１１から抜け出ることを防止するために、チューブ接続体１２は、長円筒部１２ａの端部に半径方向外側に向かって拡がる抜け止め部１２ｉを備える必要がある。   However, in this case, in order to prevent the tube connecting body 12 from slipping out of the cap body 11, the tube connecting body 12 needs to include a retaining portion 12i that expands radially outward at the end of the long cylindrical portion 12a. There is.

図５及び図６に示すように、第２の変形例では、液体収容体２０の口部２１に設けられた膜２３を穿通可能な穿通部１２ｊ，１２ｋを、コネクタ１０が備えている。液体収容体２０には、特にキャップを取り外した際や、コネクタ１０を装着する際に、内部の液体が漏れ出ないように、口部２１に樹脂フイルム等からなる膜２３を備えたものがある。   As shown in FIGS. 5 and 6, in the second modification, the connector 10 is provided with penetrating portions 12 j and 12 k that can penetrate the film 23 provided on the mouth portion 21 of the liquid container 20. Some liquid containers 20 are provided with a film 23 made of a resin film or the like in the mouth portion 21 so that the liquid inside does not leak particularly when the cap is removed or when the connector 10 is attached. .

そこで、コネクタ１０が穿通部１２ｊ，１２ｋを備えることにより、液体収容体２０の口部２１にコネクタ１０を装着する際に、膜２３が穿通部で穿通されるので、液体収容体２０の内部の液体が漏れ出るおそれがない。   Therefore, since the connector 10 includes the penetration portions 12j and 12k, the membrane 23 is penetrated by the penetration portion when the connector 10 is attached to the mouth portion 21 of the liquid accommodation body 20. There is no risk of liquid leaking.

例えば、図５に示すように、チューブ接続体１２の連結部１２ｆに、口部２１側に延びる矩形板状等の穿通部１２ｊを形成してもよい。   For example, as shown in FIG. 5, a penetrating portion 12 j such as a rectangular plate extending toward the mouth portion 21 may be formed in the connecting portion 12 f of the tube connecting body 12.

また、図６に示すように、チューブ接続体１２の長円筒部１２ａの口部２１側の端部から口部２１側に延びる円筒状の等の穿通部１２ｋを形成してもよい。   Moreover, as shown in FIG. 6, you may form the cylindrical penetration part 12k extended from the edge part by the side of the mouth part 21 of the long cylindrical part 12a of the tube connection body 12 to the mouth part 21 side.

さらに、図３又は図４のようにチューブ接続体１２の連結部１２ｆを備えない場合、図示しないが、キャップ体１１の蓋部１１ｂに口部２１側に延びる矩形板状等の穿通部を形成してもよい。   Further, when the connecting portion 12f of the tube connecting body 12 is not provided as shown in FIG. 3 or FIG. 4, although not shown, a penetrating portion such as a rectangular plate extending toward the mouth portion 21 is formed in the lid portion 11b of the cap body 11. May be.

以上、本発明の実施形態について説明したが、本発明はこれに限定されない。例えば、チューブ接続体１２の接続穴１２ｃにチューブ３０を嵌入させることにより、チューブ接続体１２をチューブ３０に接続しているが、これに限定されない。例えば、チューブ３０にチューブ接続体１２の長円筒部１２ａを嵌入させることにより、チューブ接続体１２をチューブ３０に接続していてもよい。   As mentioned above, although embodiment of this invention was described, this invention is not limited to this. For example, the tube connection body 12 is connected to the tube 30 by fitting the tube 30 into the connection hole 12c of the tube connection body 12, but the present invention is not limited to this. For example, the tube connector 12 may be connected to the tube 30 by fitting the elongated cylindrical portion 12 a of the tube connector 12 into the tube 30.
