技術分野  Technical field
[0001] 本発明は、仮固定部材、コネクタ組立体および輸液チューブセットに関する。  The present invention relates to a temporary fixing member, a connector assembly, and an infusion tube set.
背景技術  Background art
[0002] 輸液、輸血、栄養投与等に用いる液体の流路接続を必要とする医療用具において は、薬液、血液、流動食等の液体を持続的、一時的に流す際、液体の流路（回路）の 接続、脱離を必要に応じて行う必要がある。このとき、回路の途中に液体の流路同士 を接続する接続具を取り付けることが知られている。このような接続具の代表的なもの としては、例えば、特許文献 1に記載されたものがある。  [0002] In a medical device that requires connection of a liquid flow path used for infusion, blood transfusion, nutritional administration, etc., a liquid flow path ( Circuit) must be connected and disconnected as necessary. At this time, it is known to attach a connector for connecting the liquid flow paths to each other in the circuit. A typical example of such a connection tool is described in Patent Document 1.
[0003] この接続具（コネクタ）は、ォスコネクタ部と、メスコネクタ部と、オスロック部と、メス口 ック部とを有するものである。このような構成の接続具同士を接続した際には、一方の 接続具のオスロック部と他方の接続具のメスロック部との係合位置に応じて、コネクタ 部同士が未だ連通しな!/、ハーフロック状態（ロック前状態（ロック準備状態） )と、コネ クタ部同士を連通させるロック状態とを取り得る。  [0003] This connector (connector) has a male connector part, a female connector part, a male lock part, and a female mouth part. When connecting the connectors having such a configuration, the connector portions are not yet in communication with each other according to the engagement position between the male lock portion of one connector and the female lock portion of the other connector! /, A half-locked state (pre-locked state (lock ready state)) and a locked state where the connector parts communicate with each other can be taken.
[0004] しかしながら、ハーフロック状態とロック状態とでは、接続した接続具同士の外観が ほとんど変わらないため、これらの接続具同士が、現在、ハーフロック状態なのかロッ ク状態なのかが分力、りづらい（見分けづらい）という場合があった。また、一方の接続 具のオスロック部と他方の接続具のメスロック部との着脱を繰り返す、特に、ロック状 態とハーフロック状態とを繰り返すこととなり、ロック状態とハーフロック状態とを誤って 認識する場合も考えられる。  [0004] However, since the appearances of the connected connectors are almost the same between the half-locked state and the locked state, whether these connectors are currently in the half-locked state or the locked state is a component. There were cases where it was difficult to distinguish. In addition, the male lock part of one connector and the female lock part of the other connector are repeatedly attached, and in particular, the lock state and the half lock state are repeated, so that the lock state and the half lock state are erroneously recognized. Cases are also conceivable.

The groove 612 is formed along the y-axis (parallel to the y-axis). The groove 613 is formed along the positive direction of the X axis.
[0045] また、図 2に示すように、ォスコネクタ部本体 61は、上板 614の z軸負方向に下板 6 15を有している。この下板 615は、その形状が半円状をなしており、上板 614と同心 的に配置されている。 [0046] 管状部 62は、ォスコネクタ部本体 61から y軸負方向に突出して形成されている。こ の管状部 62は、液体が通過する液体流路 (ォス側内腔部） 621と、ルアーテーパ部 6 22とを有している。 Further, as shown in FIG. 2, the male connector portion body 61 has a lower plate 615 in the negative z-axis direction of the upper plate 614. The lower plate 615 has a semicircular shape and is disposed concentrically with the upper plate 614. The tubular portion 62 is formed to protrude from the male connector portion body 61 in the negative y-axis direction. The tubular portion 62 includes a liquid flow path (a male side lumen portion) 621 through which a liquid passes and a luer taper portion 622.
[0047] ルアーテーパ部 622のォスコネクタ部本体 61側の部分は、テーパ状としてもよいし 、ストレート状としてもよいし、その外径を蓋部 73の接続口 732の内径よりも小さい寸 法に設定してもよい。このようにして、ロック状態におけるルアーテーパ部 622のォス コネクタ部本体 61側の部分と蓋部 73との嵌合強度を弁体 51の付勢力に比べて、小 さく設定するのが好ましい。これによつて、ロック状態を解除したとき、コネクタ 5A'の ォスコネクタ部 6とコネクタ 5Aのメスコネクタ部 7Bとを自動的に外すことができる。  [0047] The male connector 61 side portion of the luer taper portion 622 may be tapered or straight, and the outer diameter thereof is set to be smaller than the inner diameter of the connection port 732 of the lid portion 73. May be. In this way, it is preferable that the fitting strength between the portion of the luer taper portion 622 on the male connector portion main body 61 side and the lid portion 73 in the locked state is set smaller than the urging force of the valve body 51. Thereby, when the locked state is released, the male connector portion 6 of the connector 5A ′ and the female connector portion 7B of the connector 5A can be automatically disconnected.
[0048] 液体流路 621は、ォスコネクタ部本体 61内に連通している。  The liquid flow path 621 communicates with the male connector section main body 61.
ルアーテーパ部 622は、ォスコネクタ部 6の開口部 623側の外周部に、その外径が 開口部 623の方向に向かって漸減するように形成されている。  The luer taper portion 622 is formed on the outer peripheral portion of the male connector portion 6 on the opening 623 side so that the outer diameter gradually decreases in the direction of the opening 623.
[0049] また、管状部 62には、キャップ 30が着脱自在に装着されている。このキャップ 30は 、コネクタ 5Aを輸液投与部側コネクタ 26に接続するときに、取り外される。  [0049] Further, the cap 30 is detachably attached to the tubular portion 62. The cap 30 is removed when the connector 5A is connected to the infusion administration unit side connector 26.
[0050] メスコネクタ部 7Aおよび 7Bは、それぞれ、コネクタ 5A'のォスコネクタ部 6が接続可 能な部位である（本実施形態では、メスコネクタ部 7Bにコネクタ 5A'のォスコネクタ部 6が接続される）。メスコネクタ部 7Aとメスコネクタ部 7Bとの形状（構成）は、ほぼ同一 であるため、以下、メスコネクタ部 7Bについて代表的に説明する。  [0050] Each of the female connector portions 7A and 7B is a portion to which the male connector portion 6 of the connector 5A 'can be connected (in this embodiment, the male connector portion 6 of the connector 5A' is connected to the female connector portion 7B). ). Since the shape (configuration) of the female connector portion 7A and the female connector portion 7B are substantially the same, the female connector portion 7B will be described below representatively.
[0051] 図 11に示すように、メスコネクタ部 7Bは、メスコネクタ部本体 72と、管状をなす蓋部  As shown in FIG. 11, the female connector portion 7B includes a female connector portion main body 72 and a tubular lid portion.

[0052] 図 11に示すメスコネクタ部本体 72は、その先端部に、形状が有底筒状の弁体設置 部 721が形成されている。この弁体設置部 721は、内部の基端側に第 2の内腔部 (メ ス側内腔部） 723と、先端側に第 2の内腔部 723と連通する第 3の内腔部 (メス側内 腔部） 724とが形成されている。第 2の内腔部 723は、その内径が後述する蓋部 73に 形成された第 1の内腔部（メス側内腔部） 731より拡径しており、第 3の内腔部 724 (内 周面 728)は、その内径が第 2の内腔部 723より縮径している。この第 3の内腔部 724 の内径は、後述する弁体 51の胴部 55 (外周面 551)の最大外径より若干大きいのが 好ましい。 [0053] また、メスコネクタ部本体 72の底面 722の中心部には、管状体で構成された内部 突起 725が設けられている。コネクタ 5A'のォスコネクタ部 6を第 1の内腔部 731 (接 続口 732)に接続して、弁体 51が押圧され始めたとき、この内部突起 725により、弁 体 51の内部が支えられて、弁体 51に座屈が生じる（弁体 51がくの字状に折れる）の を防止することができる（図 12参照）。また、液体がコネクタ 5A内を通過するに際し、 液体の滞留が生じるのを防ぐことができる。 A female connector part main body 72 shown in FIG. 11 is formed with a bottomed cylindrical valve body installation part 721 at the tip thereof. This valve body installation portion 721 has a second lumen portion (mes side lumen portion) 723 on the inner proximal end side and a third lumen portion communicating with the second lumen portion 723 on the distal end side. (Female side lumen) 724 is formed. The second lumen 723 has an inner diameter that is larger than that of the first lumen (female side lumen) 731 formed in the lid 73 described later, and the third lumen 724 ( The inner peripheral surface 728) has a smaller inner diameter than the second lumen 723. The inner diameter of the third lumen 724 is preferably slightly larger than the maximum outer diameter of a body 55 (outer peripheral surface 551) of the valve body 51 described later. [0053] Further, an inner protrusion 725 made of a tubular body is provided at the center of the bottom surface 722 of the female connector main body 72. When the male connector portion 6 of the connector 5A 'is connected to the first lumen portion 731 (connection port 732) and the valve body 51 starts to be pressed, the internal protrusion 725 supports the inside of the valve body 51. Thus, it is possible to prevent the valve body 51 from buckling (the valve body 51 is bent into a dogleg shape) (see FIG. 12). Further, it is possible to prevent the liquid from staying when the liquid passes through the connector 5A.
[0054] また、この内部突起 725は、その内腔がォスコネクタ部本体 61の内部に形成され、 液体が通過可能な流路 611に連通している。これにより、第 2の内腔部 723と第 3の 内腔部 724とは、内部突起 725および流路 611を介して液体流路 621に連通してい  Further, the inner protrusion 725 has a lumen formed inside the male connector portion body 61 and communicates with a flow path 611 through which liquid can pass. Thus, the second lumen portion 723 and the third lumen portion 724 communicate with the liquid channel 621 via the internal protrusion 725 and the channel 611.
[0055] また、弁体設置部 721の外周面 726の先端側には、基端側より拡径した段差部 72 7が設けられている。 Further, a stepped portion 727 having a diameter larger than that of the base end side is provided on the distal end side of the outer peripheral surface 726 of the valve body installation portion 721.
[0056] 図 11に示す蓋部 73は、内部に弁体 51を収納する空間（メス側内腔部）を有し、メス コネクタ部本体 72の基端側（弁体設置部 721)に連結されるものである。  [0056] The lid 73 shown in FIG. 11 has a space (female side lumen) for accommodating the valve body 51 therein, and is connected to the proximal end side (valve body installation part 721) of the female connector main body 72. It is what is done.
[0057] 蓋部 73の内部には、後述する弁体 51の頭部 50が揷入可能な第 1の内腔部 731と 、第 1の内腔部 731に連通し、第 1の内腔部 731より拡径した嵌合部 733とが形成さ れている。  [0057] Inside the lid 73, a first lumen 731 into which a head 50 of a valve body 51 (to be described later) can be inserted is communicated with the first lumen 731 and the first lumen 731 is inserted. A fitting portion 733 having a diameter larger than that of the portion 731 is formed.
[0058] 第 1の内腔部 731は、その形状が弁体 51の頭部 50の外形に対応するよう形成され ている。また、第 1の内腔部 731の基端側には、コネクタ 5A'のォスコネクタ部 6を接 続するための接続口（接続部） 732が形成されており、その径は、第 1の内腔部 731 の先端側の径より縮径して!/、る。  [0058] The first lumen 731 is formed so that its shape corresponds to the outer shape of the head 50 of the valve body 51. In addition, a connection port (connection portion) 732 for connecting the male connector portion 6 of the connector 5A ′ is formed on the proximal end side of the first lumen portion 731, and the diameter thereof is the first inner portion 731. Reduce the diameter of the cavity 731 from the diameter on the tip side!
[0059] 第 1の内腔部 731の内周面 734には、軸方向に沿い、第 1の内腔部 731の径方向 に突出した複数のリブ 735が設けられている。コネクタ 5A'のォスコネクタ部 6をコネ クタ 5A (接続口 732)に接続したとき、このリブ 735により、弁体 51が支えられて、弁 体 51に座屈が生じる（弁体 51が倒れる）のを防止することができる。また、リブ 735の 個数は、特に限定されず、例えば、 2〜； 10個であるのが好ましぐ 4〜8つであるのが より好ましい。  A plurality of ribs 735 projecting in the radial direction of the first lumen portion 731 are provided on the inner peripheral surface 734 of the first lumen portion 731 along the axial direction. When the male connector portion 6 of the connector 5A 'is connected to the connector 5A (connection port 732), the valve body 51 is supported by the rib 735, and the valve body 51 is buckled (the valve body 51 falls). Can be prevented. Further, the number of ribs 735 is not particularly limited, and for example, 2 to 10 is preferable, and 4 to 8 is more preferable.
[0060] 嵌合部 733の先端側には、弁体設置部 721の段差部 727と嵌合する段差部 736 が形成されており、その径は、嵌合部 733の基端側の径より拡径している。また、段 差部 736の内径は、弁体設置部 721の段差部 727の外径とほぼ同等またはそれより 若干小さいのが好ましい。これにより、蓋部 73 (段差部 736)とメスコネクタ部本体 72 ( 段差部 727)とが強固に嵌合 (連結)する (液密に接する)ことができ、よって、コネクタ 5Aの内部の液体が漏れるのを防止することができる。また、蓋部 73とメスコネクタ部 本体 72とが連結した際、第 1の内腔部 731と第 2の内腔部 723とが連通し、第 1の内 腔部 731、第 2の内腔部 723および第 3の内腔部 724で形成された空間に弁体 51を 設置 (収納）することができる。 [0060] On the distal end side of the fitting part 733, a step part 736 that fits with the step part 727 of the valve body installation part 721 is provided. The diameter is larger than the diameter of the base end side of the fitting portion 733. Further, the inner diameter of the stepped portion 736 is preferably substantially the same as or slightly smaller than the outer diameter of the stepped portion 727 of the valve element installing portion 721. As a result, the lid 73 (the step 736) and the female connector main body 72 (the step 727) can be firmly fitted (connected) (in contact with the liquid), and thus the liquid inside the connector 5A can be connected. Can be prevented from leaking. When the lid 73 and the female connector main body 72 are connected, the first lumen 731 and the second lumen 723 communicate with each other, and the first lumen 731 and the second lumen The valve body 51 can be placed (stored) in the space formed by the portion 723 and the third lumen portion 724.
[0061] なお、メスコネクタ部本体 72と蓋部 73との固定方法としては、嵌合に限定されず、 例えば、かしめ、接着剤による接着、熱融着、超音波融着等の融着等であってもよい [0061] The method of fixing the female connector portion main body 72 and the lid portion 73 is not limited to fitting. For example, caulking, adhesion with an adhesive, heat fusion, fusion such as ultrasonic fusion, etc. May be

7Aは、その中心線がォスコネクタ部 6の中心線と平行で、かつ、メスコネクタ部 7Aの 開口部 71 (接続口 732)とォスコネクタ部 6の開口部 623とが互いに反対の方向を向 くように配置されている。 The center line of 7A is parallel to the center line of male connector part 6, and opening 71 (connection port 732) of female connector part 7A and opening part 623 of male connector part 6 are oriented in opposite directions. Is arranged.
[0063] これにより、例えば、図 13に示すように 2つのコネクタ 5A同士を接続する際、一方 のォスコネクタ部 6と他方のメスコネクタ部 7Aとを接続することで、ほぼ直線的にコネ クタ 5A同士を接続することができる。 Accordingly, for example, as shown in FIG. 13, when two connectors 5A are connected to each other, by connecting one male connector portion 6 and the other female connector portion 7A, the connector 5A is almost linearly connected. You can connect each other.
[0064] メスコネクタ部 7Bは、ォスコネクタ部本体 61 (ォスコネクタ部 6)に対し、 x軸正方向 に設けられている。すなわち、メスコネクタ部 7Bは、その中心線がォスコネクタ部 6の 中心線とほぼ直交するように設けられている。 [0064] The female connector portion 7B is provided in the positive x-axis direction with respect to the male connector portion body 61 (the male connector portion 6). That is, the female connector portion 7B is provided such that the center line thereof is substantially orthogonal to the center line of the male connector portion 6.
[0065] このようなメスコネクタ部 7Aおよび 7Bが設けられていることにより、異なる 2方向から 液体をォスコネクタ部 6へ送ることができたり、ォスコネクタ部 6からの液体を異なる 2 方向へ分岐させたりすることができる。 [0065] By providing such female connector portions 7A and 7B, liquid can be sent to the male connector portion 6 from two different directions, or the liquid from the male connector portion 6 can be branched into two different directions. can do.
[0066] 図 11および図 12に示すように、メスコネクタ部 7A内およびメスコネクタ部 7B内には[0066] As shown in FIGS. 11 and 12, in the female connector portion 7A and in the female connector portion 7B,
、それぞれ、弁体 51が収納（固定）されている。 In each case, the valve body 51 is housed (fixed).
[0067] 各弁体 51は、弾性材料で構成されて!/、る。この弾性材料としては、例えば、天然ゴ ム、イソプレンゴム、ブタジエンゴム、スチレン ブタジエンゴム、二トリノレゴム、クロロブ レンゴム、ブチルゴム、アクリルゴム、エチレン プロピレンゴム、ヒドリンゴム、ウレタン ゴム、シリコーンゴム、フッ素ゴムのような各種ゴム材料や、スチレン系、ポリオレフイン 系、ポリ塩化ビュル系、ポリウレタン系、ポリエステル系、ポリアミド系、ポリブタジエン 系、トランスポリイソプレン系、フッ素ゴム系、塩素化ポリエチレン系等の各種熱可塑 性エラストマ一が挙げられ、これらのうちの 1種または 2種以上を混合して用いることが できる。このような弾性材料を用いることにより、弁体 51の頂面 511に適度な弾性を 得ること力 Sでき、よって、コネクタ 5A、 5A'同士を接続した際に頂面 511がォスコネク タ部 6の開口部（端部） 623に密着ことができる（図 12参照）。 [0067] Each valve body 51 is made of an elastic material. Examples of this elastic material include natural rubber. Rubber, isoprene rubber, butadiene rubber, styrene butadiene rubber, nitrinole rubber, chlorobrene rubber, butyl rubber, acrylic rubber, ethylene propylene rubber, hydrin rubber, urethane rubber, silicone rubber, fluorine rubber, styrene-based, polyolefin-based , Polychlorinated burs, polyurethanes, polyesters, polyamides, polybutadienes, trans polyisoprenes, fluororubbers, chlorinated polyethylenes, etc. Two or more types can be mixed and used. By using such an elastic material, it is possible to obtain an appropriate elasticity S on the top surface 511 of the valve body 51. Therefore, when the connectors 5A and 5A ′ are connected to each other, the top surface 511 is connected to the connector portion 6. It can be in close contact with the opening (end) 623 (see FIG. 12).
[0068] 図 10に示すように、弁体 51は、頭部 50と、頭部 50の先端側に設けられた（形成さ れた)胴部 55とを有している。  As shown in FIG. 10, the valve body 51 includes a head portion 50 and a body portion 55 provided (formed) on the distal end side of the head portion 50.
[0069] 頭部 50は、その形状が有底筒状をなしており、液体が通過可能な内腔部 515と、 平面状の頂面 511 (底部 513)力も内腔部 515に到達するスリット 512とが形成されて いる。このスリット 512は、その形状がほぼ一文字状をなしている。スリット 512の形状 力 Sこのように簡単な形状であることにより、より容易に (確実に)スリット 512が開口する (開く）ことができる。また、頂面 511が平面状をなしていることにより、頂面 511 (スリツ ト 512)を容易に消毒することができる。  [0069] The head 50 has a bottomed cylindrical shape, and has a lumen 515 through which a liquid can pass, and a planar top surface 511 (bottom 513) force that also reaches the lumen 515. 512 are formed. The slit 512 has a substantially single character shape. Slit 512 Shape Force S With such a simple shape, the slit 512 can be opened (opened) more easily (reliably). Further, since the top surface 511 is flat, the top surface 511 (slit 512) can be easily disinfected.
[0070] 図 7に示すように、頂面 511は、メスコネクタ部 7B (メスコネクタ部 7Aも同様）の開口 部 71から露出している。また、この頂面 511は、メスコネクタ部 7Bの端面とほぼ同一 平面上に位置している。  As shown in FIG. 7, the top surface 511 is exposed from the opening 71 of the female connector portion 7B (the same applies to the female connector portion 7A). Further, the top surface 511 is located on substantially the same plane as the end surface of the female connector portion 7B.
[0071] 頭部 50は、その頂面 511付近の外径が胴部 55に向って（軸方向に向って）漸増す るテーパ状をなすテーパ部 56と、その先端に設けられた外径一定部 57とを有して!/ヽ  [0071] The head 50 has a tapered portion 56 in which the outer diameter near the top surface 511 gradually increases toward the trunk portion 55 (in the axial direction), and the outer diameter provided at the tip thereof. With fixed part 57! / ヽ
[0072] また、テーパ部 56には、テーパ部 56の一部を除去した切欠き部 561が形成されて いる。すなわち、頭部 50には、テーパ部 56と外径一定部 57とをまたぐように除去した 切欠き部 561が形成されている。 [0072] Further, the tapered portion 56 is formed with a notch 561 from which a part of the tapered portion 56 is removed. That is, the head portion 50 is formed with a notch portion 561 that is removed so as to straddle the tapered portion 56 and the constant outer diameter portion 57.
[0073] これにより、コネクタ 5Aに接続（揷入）されているコネクタ 5A，のォスコネクタ部 6を 抜去したとき、すなわち、ロック状態を解除したとき、弁体 51 (頭部 50)が蓋部 73の第 1の内腔部 731により容易に入り込むことができ、よって、より確実にスリット 512が閉 じること力 Sでさる。 [0073] Thereby, when the male connector portion 6 of the connector 5A connected (inserted) to the connector 5A is removed, that is, when the locked state is released, the valve body 51 (head portion 50) is moved to the lid portion 73. The first It can be easily penetrated by the lumen portion 731 of 1, and therefore, the force S can be more reliably closed by the slit 512.
[0074] また、頭部 50は、スリット 512が閉じる際に押される、突出した 2つの当接部 52を備 えている。これら 2つの当接部 52は、それぞれ、頭部 50の頂面 511付近に形成され 、スリット 512が閉じる方向（図 10中、矢印方向）と反対方向に突出している。  [0074] The head 50 includes two protruding contact portions 52 that are pushed when the slit 512 is closed. Each of these two contact portions 52 is formed in the vicinity of the top surface 511 of the head 50 and protrudes in a direction opposite to the direction in which the slit 512 closes (the arrow direction in FIG. 10).
[0075] このような当接部 52により、頭部 50が蓋部 73の第 1の内腔部 731に揷入されてい るとき、第 1の内腔部 731の内周面 734が当接部 52を押圧するため、スリット 512をよ り確実に閉じることができる（図 11参照）。また、これにより、コネクタ 5A内の液体の圧 力（内圧）に対する耐圧性を向上させることができる。  [0075] With such a contact portion 52, when the head portion 50 is inserted into the first lumen portion 731 of the lid portion 73, the inner peripheral surface 734 of the first lumen portion 731 abuts. Since the portion 52 is pressed, the slit 512 can be closed more securely (see FIG. 11). This also improves the pressure resistance against the pressure (internal pressure) of the liquid in the connector 5A.
[0076] 以上のように構成された頭部 50は、コネクタ 5A，のォスコネクタ部 6が接続されてい ないとき、スリット 512が閉じた状態で蓋部 73の第 1の内腔部 731に揷入されている（ 図 11参照)。  The head 50 configured as described above is inserted into the first lumen portion 731 of the lid portion 73 with the slit 512 closed when the male connector portion 6 of the connector 5A is not connected. (See Figure 11).
[0077] 図 10に示すように、胴部 55は、蛇腹状をなした筒状体で構成されている。すなわち 、胴部 55は、外形において大径リング部 552と小径リング部 553とが軸方向に交互 に配列された蛇腹状をなしている。このような胴部 55は、弁体 51をその先端側から 基端側に向って (頭部 50が蓋部 73の第 1の内腔部 731に揷入される方向に）付勢す る変形部 (付勢手段）として機能してレ、る。  As shown in FIG. 10, the body portion 55 is formed of a cylindrical body having a bellows shape. That is, the body portion 55 has a bellows shape in which a large-diameter ring portion 552 and a small-diameter ring portion 553 are alternately arranged in the axial direction in the outer shape. Such a body portion 55 urges the valve body 51 from the distal end side toward the proximal end side (in a direction in which the head portion 50 is inserted into the first lumen portion 731 of the lid portion 73). It functions as a deformation part (biasing means).
[0078] このように胴部 55が変形部として機能していることにより、別途に付勢手段を構成 するための部品をコネクタ 5Aに設ける必要がなぐ部品点数の減少、構造の簡素化 に寄与することができる。  [0078] Since the body portion 55 functions as a deforming portion as described above, it is possible to reduce the number of components and to simplify the structure, because it is not necessary to separately provide the connector 5A with a component for constituting the biasing means. can do.

That is, the number of recesses (small-diameter ring portion 553) in the bellows-like portion is four or five.
[0081] 図 1、図 2、図 7および図 8に示すように、オスロック部 8Aは、基部（オスロック部本体 ) 81と、基部 81から突出する突出部 82と、突出部 82に設けられた一対の爪部 83A、 83Aと、各爪部 83Aをそれぞれ付勢する付勢部 84とを有している。なお、図 8に示 すオスロック部 8Aは、コネクタ 5A，に属するものである力 図 1に示すコネクタ 5Aに 属するオスロック部 8Aと同じ構成となっている。このため、ここでは、図 8も参照して説 明する。 As shown in FIG. 1, FIG. 2, FIG. 7 and FIG. 8, the male lock portion 8A is provided on the base portion (male lock portion main body) 81, the protrusion portion 82 protruding from the base portion 81, and the protrusion portion 82. It has a pair of claw parts 83A and 83A, and a biasing part 84 that biases each claw part 83A. As shown in Fig. 8. The male lock 8A has the same configuration as the male lock 8A belonging to the connector 5A shown in FIG. For this reason, the explanation will be made with reference to FIG.
[0082] 基部 81は、その形状が長尺状をなして!/、る。  [0082] The base 81 has a long shape! /.
基部 81 (オスロック部 8A)の z軸正方向には、基部 81に隣接してォスコネクタ部 6の ォスコネクタ部本体 61が固着（固定)されている。また、基部 81の y軸負方向には、そ の方向に突出した突出部 82が形成されている。  In the positive z-axis direction of the base part 81 (male lock part 8A), the male connector part body 61 of the male connector part 6 is fixed (fixed) adjacent to the base part 81. In addition, in the negative y-axis direction of the base portion 81, a protruding portion 82 that protrudes in that direction is formed.
[0083] 突出部 82の y軸正および負方向には、それぞれ、爪部 83Aおよび 83Aが設けられ ている。両爪部 83A、 83Aは、それぞれの端部（ォス側係合部 832が）が互いに X軸 方向（図 8中上下方向）に接近 '離間する。 [0083] Claw portions 83A and 83A are provided in the y-axis positive and negative directions of the protrusion 82, respectively. The end portions of the claw portions 83A and 83A (the male side engaging portion 832) approach and separate from each other in the X-axis direction (vertical direction in FIG. 8).
[0084] 各爪部 83Aの端部には、それぞれ、当該端部の一部を切欠いた（欠損させた）よう なォス側係合部 832が設けられて!/、る。 [0084] Each end portion of the claw portion 83A is provided with a male side engaging portion 832 in which a part of the end portion is cut out (deleted).
[0085] 付勢部 84は、突出部 82と爪部 83Aとの間に設けられている。この付勢部 84は、両 爪部 83A、 83Aのそれぞれの端部（ォス側係合部 832)が互いに離間するように各 爪部 83Aを付勢する。 [0085] The urging portion 84 is provided between the protruding portion 82 and the claw portion 83A. The urging portion 84 urges the claw portions 83A so that the end portions (the male side engaging portions 832) of the claw portions 83A and 83A are separated from each other.
[0086] このような構成のオスロック部 8Aは、ォスコネクタ部 6と対応する（隣接した）位置に ある（図 7参照）。また、オスロック部 8Aとォスコネクタ部 6とは、それぞれ、 y軸負方向 に向力、つて形成されている、すなわち、接続方向（突出方向）が互いに平行となって いる。  [0086] The male lock portion 8A having such a configuration is in a position corresponding to (adjacent to) the male connector portion 6 (see FIG. 7). Further, the male lock portion 8A and the male connector portion 6 are each formed with an urging force in the negative y-axis direction, that is, the connection direction (projection direction) is parallel to each other.
[0087] 図 1に示すように、メスロック部 9Aおよび 9Bは、それぞれ、コネクタ 5A'のオスロック 部 8Aが連結可能な部位である（本実施形態では、メスロック部 9Bにコネクタ 5A'の オスロック部 8Aが接続される）。  [0087] As shown in FIG. 1, female lock portions 9A and 9B are portions to which male lock portion 8A of connector 5A 'can be connected (in this embodiment, male lock portion 8A of connector 5A' is connected to female lock portion 9B. Is connected).
[0088] 図 7に示すように、メスロック部 9Aは、基部 81 (オスロック部 8A)に対し、 y軸正方向 に設けられている。また、メスロック部 9Bは、基部 81 (オスロック部 8A)に対し、 X軸正 方向に設けられている。メスロック部 9Aとメスロック部 9Bとの形状（構成）は、ほぼ同 一であるため、以下、メスロック部 9Bについて代表的に説明する。  As shown in FIG. 7, the female lock portion 9A is provided in the positive y-axis direction with respect to the base portion 81 (male lock portion 8A). The female lock portion 9B is provided in the positive direction of the X axis with respect to the base portion 81 (male lock portion 8A). Since the shape (configuration) of the female lock portion 9A and the female lock portion 9B are substantially the same, the female lock portion 9B will be described below representatively.
[0089] メスロック部 9Bは、全体形状としてほぼ管状をなしている。  [0089] The female lock portion 9B has a substantially tubular shape as a whole.
図 8 (図 9も同様）に示すように、メスロック部 9Bには、コネクタ 5A'のオスロック部 8A の各ォス側係合部 832と係合可能なメス側係合部 91と、接続されたコネクタ 5A'の オスロック部 8Aの各爪部 83Aを操作可能な操作部 93とが設けられている。 As shown in Fig. 8 (also in Fig. 9), the female lock 9B has a male lock 8A on the connector 5A '. Female-side engaging portions 91 that can be engaged with each male-side engaging portion 832 and an operating portion 93 that can operate each claw portion 83A of the male lock portion 8A of the connected connector 5A '. .
[0090] 図 8に示すように、メス側係合部 91は、メスロック部 9Bの開口部 94側の内周部が X 軸負方向（図 8中、左方向）に向って漸減するように形成されている。図 8 (c)に示す ように、メス側係合部 91の端部 911が、コネクタ 5A'のオスロック部 8Aのォス側係合 部 832に係合することにより、コネクタ 5A (メスロック部 9B)とコネクタ 5A，（オスロック 部 8A)と力 Sロック状態となる。  As shown in FIG. 8, the female side engaging portion 91 is configured so that the inner peripheral portion on the opening 94 side of the female lock portion 9B gradually decreases in the X-axis negative direction (left direction in FIG. 8). Is formed. As shown in FIG. 8 (c), the end 911 of the female side engaging portion 91 engages with the male side engaging portion 832 of the male lock portion 8A of the connector 5A ', so that the connector 5A (female lock portion 9B ) And connector 5A (male lock 8A) and force S locked.
[0091] 図 7に示すように、操作部 93は、メス側係合部 91に対して、 x軸負方向に設けられ た小片で構成されている。この操作部 93は、ロック状態のコネクタ 5A，（オスロック部 8A)の両爪部 83Aの端部を互いに接近させるように、各爪部 83Aを操作（押圧）する  As shown in FIG. 7, the operation portion 93 is configured with a small piece provided in the negative x-axis direction with respect to the female side engaging portion 91. This operation part 93 operates (presses) each claw part 83A so that the ends of both claw parts 83A of the connector 5A in the locked state (male lock part 8A) are brought close to each other.
[0092] また、操作部 93は、その外面がメス側係合部 91の外面とほぼ同一面上にあるよう に形成されている。これにより、操作部 93に対して不本意に触れる（押圧する）のを 防止すること力 Sできる。すなわち、ロック状態を不本意に解除するのを防止することが できる。 Further, the operation portion 93 is formed so that its outer surface is substantially flush with the outer surface of the female side engaging portion 91. As a result, it is possible to prevent force S from touching (pressing) the operating unit 93 unintentionally. That is, it is possible to prevent the locked state from being released unintentionally.
[0093] このような構成のメスロック部 9Bは、メスコネクタ部 7Bと対応する（隣接する）位置に ある（図 7参照）。また、メスロック部 9Bとメスコネクタ部 7Bとは、それぞれ、 z軸正方向 に向かって形成されている、すなわち、接続方向（形成方向）が互いに平行となって いる。  [0093] The female lock portion 9B having such a configuration is located at a position corresponding to (adjacent to) the female connector portion 7B (see FIG. 7). Further, the female lock portion 9B and the female connector portion 7B are each formed in the positive z-axis direction, that is, the connection direction (formation direction) is parallel to each other.
[0094] このように、コネクタ 5Aでは、ォス同士（オスロック部 8Aおよびォスコネクタ部 6)、メ ス同士（メスロック部 9Bおよびメスコネクタ部 7B)がそれぞれ対応している。これにより 、メスコネクタ部 7Bとォスコネクタ部 6とを確認することによって、コネクタ 5Aとコネクタ 5A'とを正確 (確実）に接続することができ、または、メスロック部 9Bとオスロック部 8A とを確認することによつても、コネクタ 5Aとコネクタ 5A'とを正確 (確実）に接続するこ と力 Sできる。  As described above, in the connector 5A, the males (male lock part 8A and male connector part 6) correspond to each other (female lock part 9B and female connector part 7B). Thus, by confirming the female connector portion 7B and the male connector portion 6, the connector 5A and the connector 5A 'can be accurately (reliably) connected, or the female lock portion 9B and the male lock portion 8A are confirmed. Therefore, it is possible to connect the connector 5A and the connector 5A 'accurately (reliably).
[0095] 次に、コネクタ 5A'につ!/、て説明する。  [0095] Next, the connector 5A 'will be described.
前述したように、コネクタ 5A'は、コネクタ 5Aとほぼ同様のォスコネクタ部 6およびォ スロック部 8Aと、チューブ 41が接続されるチューブ接続部 63とを備えている（例えば 、図 6参照)。 As described above, the connector 5A ′ includes the male connector portion 6 and the male lock portion 8A that are substantially the same as the connector 5A, and the tube connecting portion 63 to which the tube 41 is connected (for example, Figure 6).
[0096] ォスコネクタ部 6は、その開口部 623が X軸負方向に向力、うように配置されている。こ のォスコネクタ部 6の上板 614には、 X軸に沿った溝 616が形成されている。  The male connector portion 6 is arranged such that the opening 623 has a directing force in the negative direction of the X axis. A groove 616 along the X axis is formed in the upper plate 614 of the male connector portion 6.
[0097] また、ォスコネクタ部 6には、上板 614と下板 615との間に、一対の溝 617が形成さ ている。各溝 617は、それぞれ、 X軸に沿って形成されている。 In the male connector portion 6, a pair of grooves 617 are formed between the upper plate 614 and the lower plate 615. Each groove 617 is formed along the X axis.
[0098] チューブ接続部 63は、ォスコネクタ部 6と連通する管体で構成されたものである。こ のチューブ接続部 63を介して、チューブ 41からォスコネクタ部 6に液体が流通する。 The tube connection part 63 is configured by a pipe body that communicates with the male connector part 6. The liquid flows from the tube 41 to the male connector portion 6 through the tube connection portion 63.
[0099] このチューブ接続部 63は、ォスコネクタ部 6に対して、 X軸正方向に突出して形成さ れている。 [0099] The tube connecting portion 63 is formed so as to protrude in the positive direction of the X axis with respect to the male connector portion 6.
[0100] オスロック部 8Aは、ォスコネクタ部 6と接続方向が互いに平行となるように、当該ォ スコネクタ部 6と隣接して設けられている。すなわち、オスロック部 8Aは、突出部 82が X軸負方向に向力、うように、ォスコネクタ部 6に対して z軸負側に配置されている。  [0100] The male lock portion 8A is provided adjacent to the male connector portion 6 so that the connection direction thereof is parallel to the male connector portion 6. That is, the male lock portion 8A is disposed on the negative side of the z axis with respect to the male connector portion 6 so that the protruding portion 82 is directed in the negative direction of the X axis.
[0101] 次に、コネクタ 5Aとコネクタ 5A'との接続過程につ!/、て説明する。換言すれば、コ ネクタ 5A、 5A'同士のロック準備状態からロック状態に至るまでと、ロック状態力 口 ックを解除した状態（ロック解除状態）までとにつ!/、て説明する。  Next, the connection process between the connector 5A and the connector 5A ′ will be described. In other words, the description will be made from the state in which the connectors 5A and 5A ′ are locked to the locked state and the state in which the locked state force lock is released (the unlocked state).
[0102] 図 1、図 2、図 4および図 8 (a)に示すように、ロック準備状態では、コネクタ 5Aとコネ クタ 5A'とが互いに離間している。ここで、ロック準備状態とは、コネクタ 5Aのメスコネ クタ部 7Bとコネクタ 5A，のォスコネクタ部 6とが互いに近接し、かつ、コネクタ 5Aのメ スロック部 9Bとコネクタ 5A，のオスロック部 8Aとが互いに近接し、それらのロック部同 士がロック状態となる前の状態のことである。  [0102] As shown in Figs. 1, 2, 4, and 8 (a), in the lock ready state, the connector 5A and the connector 5A 'are separated from each other. Here, the lock ready state means that the connector part 7B of the connector 5A and the male connector part 6 of the connector 5A are close to each other, and the female lock part 9B of the connector 5A and the male lock part 8A of the connector 5A are mutually connected. It is the state before the lock unit and the lock unit are locked.
[0103] このロック準備状態から、コネクタ 5A，のオスロック部 8Aをコネクタ 5Aのメスロック部 9Bに接近させる（押し込む）。  [0103] From this lock ready state, the male lock portion 8A of the connector 5A is brought close to (push in) the female lock portion 9B of the connector 5A.
[0104] 図 8 (b)に示すように、コネクタ 5A，のオスロック部 8Aがコネクタ 5Aのメスロック部 9 B内に揷入されるのに伴って、コネクタ 5Aのメス側係合部 91がコネクタ 5A'の付勢部 84の付勢力に抗して、コネクタ 5A'の爪部 83Aを押圧する。  [0104] As shown in FIG. 8 (b), as the male lock portion 8A of the connector 5A is inserted into the female lock portion 9B of the connector 5A, the female-side engagement portion 91 of the connector 5A is The claw portion 83A of the connector 5A 'is pressed against the urging force of the urging portion 84 of 5A'.
[0105] コネクタ 5A，のオスロック部 8Aをコネクタ 5Aのメスロック部 9B内にさらに押し込むと 、コネクタ 5A'のォス側係合部 832がコネクタ 5Aのメス側係合部 91に係合する、す なわち、コネクタ 5A'とコネクタ 5Aとがロック状態となる（図 8 (c)参照）。 [0106] 図 12に示すように、ロック状態のとき、コネクタ 5A，のォスコネクタ部 6の開口部 623 力 Sコネクタ 5Aの頭部 50の頂面 511を軸方向に押圧している。これにより、胴部 55が 軸方向に変形し (圧縮され）、頭部 50が第 1の内腔部 731から移動して、第 2の内腔 部 723に入り込む。頭部 50は、それまで第 1の内腔部 731内で第 1の内腔部 731の 内周面 734に規制されていた力 第 2の内腔部 723に移動したことにより、頭部 50の 外周面の規制が解除または緩和され、その結果、軸方向の圧縮により、図 12中の矢 印方向に充分に拡径することができる、すなわち、充分に変形することができる。従つ て、スリット 512が確実かつ充分に開く（開口する）ことができる。また、これにより、弁 体 51 (スリット 512)を介して、コネクタ 5A'のォスコネクタ部 6の液体流路 621と、コネ クタ 5Aのメスコネクタ部 7Bの内部突起 725の内腔部（中空部）とが連通する、すなわ ち、流通可能に接続され、よって、例えば、輸液、輸血、栄養投与等の際、液体が円 滑に通過することができる。 [0105] When the male lock portion 8A of the connector 5A is further pushed into the female lock portion 9B of the connector 5A, the male side engaging portion 832 of the connector 5A 'engages with the female side engaging portion 91 of the connector 5A. That is, the connector 5A 'and the connector 5A are locked (see FIG. 8 (c)). As shown in FIG. 12, in the locked state, the opening 623 force of the male connector portion 6 of the connector 5A, the top surface 511 of the head 50 of the S connector 5A is pressed in the axial direction. As a result, the body portion 55 is deformed (compressed) in the axial direction, and the head portion 50 moves from the first lumen portion 731 and enters the second lumen portion 723. Since the head 50 has moved to the second lumen 723 in the first lumen 731 until it has been controlled by the inner peripheral surface 734 of the first lumen 731, the head 50 As a result, the outer peripheral surface is restrained or relaxed, and as a result, it is possible to sufficiently expand the diameter in the direction of the arrow in FIG. Accordingly, the slit 512 can be reliably and sufficiently opened (opened). In addition, as a result, through the valve body 51 (slit 512), the liquid flow path 621 of the male connector portion 6 of the connector 5A 'and the lumen portion (hollow portion) of the internal projection 725 of the female connector portion 7B of the connector 5A In other words, for example, in the case of infusion, blood transfusion, nutrition administration, etc., the liquid can pass smoothly.
[0107] また、ロック状態のとき、弁体 51の胴部 55の付勢力に抗して、コネクタ 5A'のォスコ ネクタ部 6の開口部 623が弁体 51の頭部 50を押圧するため、当該ォスコネクタ部 6 の開口部 623と頭部 50 (弁体 51)の頂面 511とが密着する。これにより、ォスコネクタ 部 6とメスコネクタ部 7Bとの接続の液密性を保持することができる、すなわち、これら を確実に液密に接続することができる。  [0107] Further, in the locked state, the opening 623 of the connector 6 of the connector 5A 'presses the head 50 of the valve 51 against the urging force of the body 55 of the valve 51. The opening 623 of the male connector 6 and the top surface 511 of the head 50 (valve body 51) are in close contact with each other. As a result, the liquid-tightness of the connection between the male connector portion 6 and the female connector portion 7B can be maintained, that is, they can be securely connected in a liquid-tight manner.
[0108] また、コネクタ 5A，とコネクタ 5Aとのロック状態の解除は、コネクタ 5Aの操作部 93を 操作することにより行われる。  [0108] Release of the locked state between connector 5A and connector 5A is performed by operating operation portion 93 of connector 5A.
[0109] 換言すれば、図 9 (a)に示すロック状態から、図 9 (b)に示すように、コネクタ 5Aの操 作部 93でコネクタ 5A'の爪部 83Aを押圧する。これにより、コネクタ 5Aのメス側係合 部 91と、コネクタ 5A'のォス側係合部 832との係合が外れる（解除される）。  In other words, from the locked state shown in FIG. 9 (a), as shown in FIG. 9 (b), the operation portion 93 of the connector 5A presses the claw portion 83A of the connector 5A ′. Thereby, the engagement between the female side engaging portion 91 of the connector 5A and the male side engaging portion 832 of the connector 5A ′ is released (released).
[0110] その後、図 9 (c)に示すように、コネクタ 5A'を引くと、コネクタ 5A'とコネクタ 5Aと力 S 互いに離間する。  Thereafter, as shown in FIG. 9 (c), when the connector 5A ′ is pulled, the connector 5A ′, the connector 5A, and the force S are separated from each other.
[0111] 前述したように、ロック状態におけるルアーテーパ部 622のォスコネクタ部本体 61 側の部分と蓋部 73の接続口 732との嵌合強度を、弁体 51の付勢力に比べて小さく 設定すれば、係合が外れたときに、コネクタ 5Aとコネクタ 5A'とが自動的に離間する [0112] このように、コネクタ 5Aとコネクタ 5A，とでは、コネクタ 5A，のオスロック部 8Aをコネ クタ 5Aのメスロック部 9B内に押し込むという簡単な操作で、コネクタ 5Aとコネクタ 5A 'と完全に接続することができる、すなわち、ロック状態とすることができる。 [0111] As described above, if the fitting strength between the male connector 61 side portion of the luer taper portion 622 in the locked state and the connection port 732 of the lid portion 73 is set smaller than the urging force of the valve body 51, When the engagement is disengaged, the connector 5A and the connector 5A 'are automatically separated from each other. [0112] In this way, connector 5A and connector 5A are completely connected to connector 5A and connector 5A 'by a simple operation of pushing male lock 8A of connector 5A into female lock 9B of connector 5A. That is, it can be in a locked state.
[0113] また、ロック状態となるのとほぼ同時に、コネクタ 5Aのメスコネクタ部 7Bとコネクタ 5 A'のォスコネクタ部 6とが液密に接続される。  [0113] Further, almost simultaneously with the locked state, the female connector portion 7B of the connector 5A and the male connector portion 6 of the connector 5A 'are liquid-tightly connected.
[0114] また、コネクタ 5Aおよび 5A' (弁体 51を除く）の構成材料としては、特に限定されな いが、例えば、ポリ塩化ビュル、ポリエチレン、ポリプロピレン、環状ポリオレフイン、ポ リスチレン、ポリ一（4ーメチルペンテン 1)、ポリカーボネート、アクリル樹脂、アタリ ルニトリル ブタジエン スチレン共重合体、ポリエチレンテレフタレート、ポリエチレ ンナフタレート等のポリエステル、ブタジエン スチレン共重合体、ポリアミド（例えば 、ナイロン 6、ナイロン 6 · 6、ナイロン 6 · 10、ナイロン 12)のような各種樹脂が挙げられ  [0114] The constituent materials of the connectors 5A and 5A '(excluding the valve body 51) are not particularly limited. For example, polybutyl chloride, polyethylene, polypropylene, cyclic polyolefin, polystyrene, poly (4 -Methylpentene 1), Polycarbonate, Acrylic resin, Atylnitrile Butadiene styrene copolymer, Polyester such as polyethylene terephthalate, Polyethylene naphthalate, Butadiene styrene copolymer, Polyamide (eg, Nylon 6, Nylon 6 · 6, Nylon 6 · 10, And various resins such as nylon 12).
[0115] 次に、仮固定部材 10について説明する。 [0115] Next, the temporary fixing member 10 will be described.
図 1〜図 4に示すように、仮固定部材 10は、コネクタ 5Aとコネクタ 5A'とを仮固定す るものである。この仮固定部材 10は、板片状の基部（本体） 101と、基部 101と並べ て（隣接して)連結された並設板 102とを有して!/、る（例えば、図 5参照）。  As shown in FIGS. 1 to 4, the temporary fixing member 10 temporarily fixes the connector 5A and the connector 5A ′. The temporary fixing member 10 includes a plate-like base (main body) 101 and a side-by-side plate 102 connected side by side (adjacent) to the base 101 (see, for example, FIG. 5). ).
[0116] 基部 101は、板状体が所望に (4箇所で）屈曲して形成されたものである。換言すれ ば、基部 101は、第 1の屈曲部 101a〜第 4の屈曲部 lOldを有するものである。第 1 の屈曲部 101aは、 L字状に屈曲した部位である。第 2の屈曲部 101bは、第 1の屈曲 部 101aの X軸負側に位置し、第 1の屈曲部 101aと反対方向に L字状に屈曲した部 位である。第 3の屈曲部 101cは、第 2の屈曲部 101の X軸負側に位置し、第 2の屈曲 部 101bと同方向に L字状に屈曲した部位である。第 4の屈曲部 lOldは、第 3の屈曲 部 101cの X軸負側に位置し、第 3の屈曲部 101cと反対方向に（第 1の屈曲部 101a と同方向に） L字状に屈曲した部位である。各屈曲部 101a〜； lOldの角度は、それ ぞれ、同等に鈍角となっている。  [0116] The base 101 is formed by bending a plate-like body as desired (at four locations). In other words, the base portion 101 has the first bent portion 101a to the fourth bent portion lOld. The first bent portion 101a is a portion bent in an L shape. The second bent portion 101b is a portion that is located on the negative X-axis side of the first bent portion 101a and is bent in an L shape in the opposite direction to the first bent portion 101a. The third bent portion 101c is a portion located on the X-axis negative side of the second bent portion 101 and bent in an L shape in the same direction as the second bent portion 101b. The fourth bent portion lOld is located on the X-axis negative side of the third bent portion 101c and bent in an L shape in the opposite direction to the third bent portion 101c (in the same direction as the first bent portion 101a). It is the part which did. The angle of each bent portion 101a to lOld is equally obtuse.
[0117] このように屈曲した基部 101には、コネクタ 5A'が保持される第 1の開口部（第 1の 保持部） 103aと、コネクタ 5Aが保持される第 2の開口部（第 2の保持部） 103bとが形 成されている。このように、これらの開口部 103a、 103bは、それぞれ、ロック準備状 態で、コネクタ 5A、 5A'同士の位置関係を仮固定した仮固定状態を保持する保持 手段としての機能を有している。以下、各開口部 103a、 103bについて、それぞれ、 説明する。 [0117] The bent base 101 has a first opening (first holding part) 103a for holding the connector 5A 'and a second opening (second holding) for holding the connector 5A. Holding part) 103b is formed. Thus, each of these openings 103a, 103b is a lock ready In this state, it has a function as a holding means for holding a temporarily fixed state in which the positional relationship between the connectors 5A and 5A ′ is temporarily fixed. Hereinafter, each of the openings 103a and 103b will be described.
[0118] 第 1の開口部 103aは、第 1の屈曲部 101a付近から第 3の屈曲部 101c付近に渡つ て開口した部位である。また、第 1の開口部 103aの形状は、基部 101の長手方向に 沿った長尺状をなしている。  [0118] The first opening 103a is a portion opened from the vicinity of the first bent portion 101a to the vicinity of the third bent portion 101c. Further, the shape of the first opening 103 a is a long shape along the longitudinal direction of the base 101.
[0119] 図 5に示すように、第 1の開口部 103aには、基部 101の裏側に、一対の第 1の爪部 105aと、一対の第 2の爪部 105bとが突出形成されている。  As shown in FIG. 5, the first opening 103a is formed with a pair of first claw portions 105a and a pair of second claw portions 105b protruding from the back side of the base 101. .
[0120] 各第 1の爪部 105aは、それぞれ、平面視で L字状をなしている。図 2に示すように、 各第 1の爪部 105aには、それぞれ、コネクタ 5A' (ォスコネクタ部 6)のチューブ接続 部 63の根元付近力 ½軸負側から当接する（支持する）。これにより、コネクタ 5A'が X 軸正方向に不本意に移動するのが規制される。  [0120] Each first claw portion 105a has an L shape in plan view. As shown in FIG. 2, each first claw portion 105a abuts (supports) from the force shaft vicinity negative side of the tube connecting portion 63 of the connector 5A ′ (male connector portion 6). This restricts the unintentional movement of the connector 5A ′ in the positive direction of the X axis.
[0121] 各第 2の爪部 105bは、それぞれ、第 1の開口部 103aの内側に向かって突出して いる。図 2に示すように、各第 2の爪部 105bには、それぞれ、コネクタ 5A' (ォスコネ クタ部 6)の下板 615の縁部が X軸正側から当接する（支持する）。これにより、コネクタ 5A'が X軸負方向に不本意に移動するのが規制される。  [0121] Each of the second claw portions 105b protrudes toward the inside of the first opening 103a. As shown in FIG. 2, the edge portion of the lower plate 615 of the connector 5A ′ (o-connector portion 6) abuts (supports) from the X-axis positive side on each second claw portion 105b. This restricts the unintentional movement of the connector 5A ′ in the negative direction of the X axis.
[0122] このような第 1の爪部 105aおよび第 2の爪部 105bにより、コネクタ 5A'が確実に仮 固定される、すなわち、仮固定状態が確実に維持される。  [0122] By such first claw portion 105a and second claw portion 105b, connector 5A 'is surely temporarily fixed, that is, the temporarily fixed state is reliably maintained.
[0123] 図 5に示すように、第 1の開口部 103aには、基部 101の表側に、一対の第 3の爪部 105cが突出形成されている。また、第 1の開口部 103aの途中には、その幅が最小と なる最小幅部 104が形成されている。仮固定部材 10では、各第 3の爪部 105cおよ び最小幅部 104が、それぞれ、コネクタ 5A'の各溝 617に入り込む（例えば、図 2参 照）。このコネクタ 5A'は、各第 2の爪部 105bの規制（仮固定)を解除することにより、 コネクタ 5Aに向かって移動することができる。各第 3の爪部 105cおよび最小幅部 10 4は、それぞれ、コネクタ 5A'が移動する際に当該コネクタ 5A'の移動を案内するガ イド部として機能する。これにより、コネクタ 5A'が円滑に移動することができる。  As shown in FIG. 5, a pair of third claw portions 105c are formed to protrude from the front side of the base portion 101 in the first opening portion 103a. Further, a minimum width portion 104 having a minimum width is formed in the middle of the first opening 103a. In the temporary fixing member 10, the third claw portions 105c and the minimum width portion 104 respectively enter the grooves 617 of the connector 5A ′ (see, for example, FIG. 2). The connector 5A ′ can move toward the connector 5A by releasing the restriction (temporary fixing) of each second claw portion 105b. Each of the third claw portions 105c and the minimum width portion 104 functions as a guide portion for guiding the movement of the connector 5A ′ when the connector 5A ′ moves. As a result, the connector 5A ′ can move smoothly.
[0124] また、前述したように、各第 3の爪部 105cおよび最小幅部 104が、それぞれ、コネク タ 5A'の各溝 617に入り込んでいる。このため、仮固定状態のコネクタ 5A'は、仮固 定部材 10からの離脱が不可能となる。 [0124] Further, as described above, each of the third claw portions 105c and the minimum width portion 104 enters each groove 617 of the connector 5A '. Therefore, the temporarily fixed connector 5A ′ is temporarily fixed. Detachment from the fixed member 10 becomes impossible.
[0125] 図 5に示すように、第 2の開口部 103bは、基部 101の第 4の屈曲部 101d側の端部 に開口した部位である。 [0125] As shown in FIG. 5, the second opening 103b is a portion opened to the end of the base 101 on the fourth bent portion 101d side.
[0126] この第 2の開口部 103は、その X軸負側に、コネクタ 5A (ォスコネクタ部本体 61)の 上板 614の外形形状に対応した形状、すなわち、円形をなす円形部 106を有してい る。円形部 106の内側には、平面視で形状力 字状をなす T字状部 107aが架設さ れている。図 1に示すように、この T字状部 107aは、コネクタ 5A (ォスコネクタ部本体 61 )の溝 612および 613のそれぞれに嵌り込む。  [0126] The second opening 103 has a shape corresponding to the outer shape of the upper plate 614 of the connector 5A (male connector portion 61), that is, a circular portion 106 forming a circle, on the X axis negative side. ing. Inside the circular portion 106, a T-shaped portion 107a having a shape-like shape in plan view is installed. As shown in FIG. 1, the T-shaped portion 107a is fitted into each of the grooves 612 and 613 of the connector 5A (male connector portion main body 61).
[0127] また、円形部 106の縁部には、 z軸負方向に向かって突出した爪部 107bが形成さ れている。図 2に示すように、この爪部 107bは、コネクタ 5A (ォスコネクタ部本体 61) の下板 615に係合する。  [0127] Further, a claw portion 107b protruding in the negative direction of the z-axis is formed at the edge of the circular portion 106. As shown in FIG. 2, the claw portion 107b engages with the lower plate 615 of the connector 5A (male connector portion main body 61).
[0128] T字状部 107aおよび爪部 107bにより、コネクタ 5Aは、ォスコネクタ部本体 61が異 なる 2箇所で支持されることとなる。これにより、コネクタ 5Aの不本意な移動が規制さ れ、よって、コネクタ 5Aが確実に仮固定される。  [0128] With the T-shaped portion 107a and the claw portion 107b, the connector 5A is supported at two different locations of the male connector portion main body 61. As a result, unintentional movement of the connector 5A is restricted, so that the connector 5A is securely fixed temporarily.
[0129] 並設板 102は、基部 101の第 2の屈曲部 101b付近および第 3の屈曲部 101c付近 で連結している。この並設板 102は、長尺状をなすものである。  The juxtaposed plates 102 are connected near the second bent portion 101b and the third bent portion 101c of the base portion 101. This juxtaposed plate 102 has a long shape.
[0130] また、並設板 102は、その端部に小片 108 (離脱防止手段）を有している。この小片 108は、基部 101 (仮固定部材 10)に仮固定されているコネクタ 5Aのキャップ 30の 頂部 301側 (y軸負側）近傍に位置している。これにより、仮固定状態でキャップ 30の ォスコネクタ部 6からの離脱を確実に防止することができる。よって、キャップ 30を取り 外すまでは、例えば、ォスコネクタ部 6を介してコネクタ 5A内が汚染されるのが防止さ れる。  Moreover, the juxtaposed plates 102 have small pieces 108 (detachment preventing means) at their ends. The small piece 108 is positioned in the vicinity of the top 301 side (y-axis negative side) of the cap 30 of the connector 5A that is temporarily fixed to the base 101 (temporary fixing member 10). Thereby, it is possible to reliably prevent the cap 30 from being detached from the male connector portion 6 in the temporarily fixed state. Therefore, until the cap 30 is removed, for example, the inside of the connector 5A is prevented from being contaminated via the male connector portion 6.
[0131] このような構成のコネクタ組立体 20 (仮固定部材 10)では、コネクタ 5A、 5A'同士 が以下の 3つの状態を取り得る。  In the connector assembly 20 (temporary fixing member 10) having such a configuration, the connectors 5A and 5A ′ can take the following three states.
[0132] 1つ目は、前述したような仮固定状態（第 1の状態）である。この仮固定状態では、コ ネクタ 5A、 5A'同士の位置関係が仮固定されているため、これらのコネクタ 5A、 5A[0132] The first is the temporarily fixed state (first state) as described above. In this temporarily fixed state, the positional relationship between the connectors 5A and 5A 'is temporarily fixed, so these connectors 5A and 5A
'同士をロック状態とすることができない。 'Cannot lock each other.
[0133] また、図 4に示すように、仮固定状態では、コネクタ 5Aのメスコネクタ部 7Bの開口部 71とコネクタ 5A'のォスコネクタ部 6の開口部 623との間に間隙 201が形成されてい る。これにより、ロック準備状態のコネクタ組立体 20では、弁体 51の変形が防止され る。例えば、コネクタ 5Aとコネクタ 5A'とが仮固定状態の輸液チューブセット 1を出荷 した場合、この輸液チューブセット 1が使用されるまでの弁体 51が長時間変形するの が防止される。これにより、弁体 51が塑性変形して、スリット 512が常時開口した状態 となるのを防止することができる。 [0133] As shown in Fig. 4, in the temporarily fixed state, the opening of the female connector 7B of the connector 5A A gap 201 is formed between 71 and the opening 623 of the male connector portion 6 of the connector 5A ′. Accordingly, the deformation of the valve body 51 is prevented in the connector assembly 20 in the lock ready state. For example, when the infusion tube set 1 in which the connector 5A and the connector 5A ′ are temporarily fixed is shipped, the valve body 51 until the infusion tube set 1 is used is prevented from being deformed for a long time. As a result, it is possible to prevent the valve body 51 from being plastically deformed and the slit 512 from being always open.
[0134] 2つ目は、コネクタ 5Aは、仮固定されて!/、る力 コネクタ 5A'の仮固定が解除されて V、る状態（第 2の状態）である。仮固定されて!/、るコネクタ 5A'を X軸負方向に押圧す ると、コネクタ 5A' (ォスコネクタ部 6)の下板 615に対する各第 2の爪部 105bの規制 (支持）が解除される。これにより、コネクタ 5A'をコネクタ 5A側に移動することができ The second is a state (second state) where the connector 5A is temporarily fixed! /, And the connector 5A ′ is temporarily fixed and the connector 5A is released from the V state. When the connector 5A 'is temporarily fixed and pressed in the X-axis negative direction, the restriction (support) of each second claw 105b against the lower plate 615 of the connector 5A' (male connector 6) is released. The As a result, the connector 5A 'can be moved to the connector 5A side.
[0135] 3つ目は、コネクタ 5A、 5A'同士がロックされたロック状態（第 3の状態）である。前 記第 2の状態で移動可能となったコネクタ 5A'を、前述したようにコネクタ 5Aに押し 込むことにより、ロック状 となる。 The third is a locked state (third state) in which the connectors 5A and 5A ′ are locked to each other. The connector 5A ′ that has become movable in the second state is pushed into the connector 5A as described above to be locked.
[0136] また、図 3に示すように、ロック状態では、コネクタ 5A'に対する支持が解除されてい る。このため、仮固定部材 10の第 1の屈曲部 101a側の端部を図 3中の上側に向かう 矢印の方向（z軸正方向）に引き上げると、コネクタ 5A'が第 1の開口部 103aから離 脱する。また、さらに仮固定部材 10を同様に引き上げると、コネクタ 5Aの溝 612およ び 613のそれぞれから T字状部 107aが外れ、その後、コネクタ 5Aの下板 615から爪 部 107bが外れる。これにより、コネクタ 5A'と同様に、コネクタ 5Aも第 2の開口部 103 bから離脱する。  Also, as shown in FIG. 3, in the locked state, the support for connector 5A ′ is released. For this reason, when the end portion on the first bent portion 101a side of the temporary fixing member 10 is pulled up in the direction of the arrow pointing upward in FIG. 3 (z-axis positive direction), the connector 5A ′ is removed from the first opening 103a. break away. Further, when the temporary fixing member 10 is further lifted in the same manner, the T-shaped portion 107a is detached from each of the grooves 612 and 613 of the connector 5A, and then the claw portion 107b is detached from the lower plate 615 of the connector 5A. Thereby, like the connector 5A ′, the connector 5A is also detached from the second opening 103b.
[0137] また、ロック状態では、コネクタ 5A，のォスコネクタ部 6とコネクタ 5Aのメスコネクタ部 7Bとは液密に接続されている。このため、コネクタ 5Aおよび 5A'を介して、輸液バッ グ 31から輸液投与部 2に液体を確実に流通させることができる。  [0137] In the locked state, the male connector portion 6 of the connector 5A and the female connector portion 7B of the connector 5A are liquid-tightly connected. Therefore, the liquid can be reliably circulated from the infusion bag 31 to the infusion administration section 2 via the connectors 5A and 5A ′.
[0138] このように、コネクタ組立体 20では、仮固定部材 10によってコネクタ 5A、 5A'同士 が仮固定され (仮固定状態となり）、コネクタ 5A、 5A'同士がロック状態となると仮固 定部材 10を取り外すことができる。  As described above, in the connector assembly 20, when the connectors 5A and 5A ′ are temporarily fixed by the temporary fixing member 10 (temporarily fixed state) and the connectors 5A and 5A ′ are locked, the temporary fixing member 10 can be removed.
[0139] これにより、コネクタ組立体 20に仮固定部材 10が設置されていれば、コネクタ 5A、 5A'がロック準備状態 (仮固定状態）となっていると判断する、すなわち、確実に視認 すること力 Sできる。また、コネクタ組立体 20から仮固定部材 10が取り外されていれば 、コネクタ 5A、 5A'がロック状態となっていると判断することができる。 [0139] Accordingly, if the temporary fixing member 10 is installed in the connector assembly 20, the connector 5A, It is possible to determine that 5A 'is in the lock ready state (temporarily fixed state), that is, to ensure visual recognition. If the temporary fixing member 10 is removed from the connector assembly 20, it can be determined that the connectors 5A and 5A 'are in a locked state.
[0140] また、この仮固定部材 10の有無によって、輸液チューブセット 1が輸液が可能か否 かを確実に判断することができる。また、仮固定状態では、小片 108によってキャップ 30を取り外すことができないため、仮固定状態のまま、コネクタ組立体 20を使用する のを防止することカできる。よって、不本意な輸液を行なうのを確実に防止することが できる。 [0140] Further, whether or not the infusion tube set 1 can be infused can be reliably determined based on the presence or absence of the temporary fixing member 10. In addition, since the cap 30 cannot be removed by the small piece 108 in the temporarily fixed state, it is possible to prevent the connector assembly 20 from being used in the temporarily fixed state. Therefore, unintentional infusion can be surely prevented.
[0141] なお、仮固定部材 10としては、特に限定されないが、例えば、コネクタ 5Aについて の説明で挙げたような各種樹脂の他、ポリアセタールを好ましく使用することができる [0141] The temporary fixing member 10 is not particularly limited. For example, in addition to the various resins mentioned in the description of the connector 5A, polyacetal can be preferably used.
〇 Yes
[0142] チューブ 41は、可撓性（柔軟性）を有し、輸液の流路を構成するものである。このチ ユーブ 41の構成材料としては、例えば、軟質ポリ塩化ビュル、エチレン—酢酸ビュル 共重合体、ポリエチレン、ポリプロピレン、ポリブタジエン等、あるいはこれらを主とす る材料が挙げられる。  [0142] The tube 41 has flexibility (softness) and constitutes a channel for infusion. Examples of the constituent material of the tube 41 include soft polychlorinated butyl chloride, ethylene-acetic acid butyl copolymer, polyethylene, polypropylene, polybutadiene, and the like, and materials mainly composed of these.
[0143] また、チューブ 41の途中には、輸液の流量を調節する流量調節手段として、スライ ド式のクレンメ (スライドクレンメ) 46と、点滴筒 44とが、それぞれ、設けられている。こ のスライドクレンメ 46としては、特に限定されず、従来公知のものを用いることができる ヽ例えば、特開 2004— 49319号公報のようなものが挙げられる。  [0143] Further, in the middle of the tube 41, a slide-type clamp (slide clamp) 46 and an infusion tube 44 are provided as flow rate adjusting means for adjusting the flow rate of the infusion, respectively. The slide clamp 46 is not particularly limited, and a conventionally known slide clamp 46 can be used. Examples thereof include those disclosed in JP-A-2004-49319.
[0144] また、スライドクレンメ 46は、ローラー型のクレンメなど、流量を調節できるものであ れば、他のものでも構わない。  [0144] The slide clamp 46 may be any other type as long as the flow rate can be adjusted, such as a roller type clamp.
[0145] 輸液バッグ 31内には、所定の輸液が収納されており、瓶針 451がこの輸液バッグ 3 1の栓 (ゴム栓）を穿通（穿刺）すると、瓶針 451を介し、輸液バッグ 31と第2の輸液チ ユーブ 4aとが接続され、輸液バッグ 31から第 2の輸液チューブ 4a側へ輸液が供給さ れ得る状態となる。 [0145] The infusion bag 31, and a predetermined infusion is accommodated, stopper bottle needle 451 of the infusion bag 3 1 (rubber stopper) the piercing (piercing), the through bottle needle 4 51, infusion bag 31 and the second infusion tube 4a are connected, and the infusion solution can be supplied from the infusion bag 31 to the second infusion tube 4a side.
[0146] 点滴筒 44は、瓶針 451の近傍に設置されている。この点滴筒 44により、輸液の流 量を目視で確認、すること力 Sできる。  The drip tube 44 is installed in the vicinity of the bottle needle 451. With this drip tube 44, it is possible to visually check and check the flow rate of the infusion.
[0147] また、逆流防止弁 49が、コネクタ 5A'と点滴筒 44の間に設置されている。逆流防 止弁 49は、輸液バッグ 31からコネクタ 5Aの方向への一方向弁である。逆流防止弁 4 9は、コネクタ 5A'と点滴筒 44の間であれば、どこに設置されても良いが、好ましくは 、コネクタ 5A'により近い所に設置される方が良い。 [0147] In addition, a check valve 49 is installed between the connector 5A 'and the drip tube 44. Backflow prevention The stop valve 49 is a one-way valve from the infusion bag 31 toward the connector 5A. The backflow prevention valve 49 may be installed anywhere as long as it is between the connector 5A ′ and the drip tube 44, but is preferably installed closer to the connector 5A ′.
[0148] 逆流防止弁 49は、その内部に、図示しない一対の板状の開閉部材が形成された 弁本体を有し、各開閉部材は、弾性力（復元力）により互いに密着し、これにより、逆 流防止弁 49内の流路は、閉塞している。輸液流が先端側から基端側に向いている 場合には、その輸液により圧力が各開閉部材の外面にかかり、開閉部材同士を密着 させるように作用する。このため、輸液は、先端側から基端側には流れない。  [0148] The backflow prevention valve 49 has a valve body in which a pair of plate-shaped opening and closing members (not shown) are formed. The opening and closing members are in close contact with each other by elastic force (restoring force). The flow path in the backflow prevention valve 49 is closed. When the infusion flow is directed from the distal end side to the proximal end side, pressure is applied to the outer surface of each opening / closing member by the infusion solution, so that the opening / closing members are brought into close contact with each other. For this reason, the infusion does not flow from the distal end side to the proximal end side.
[0149] 一方、輸液流が基端側から先端側に向いている場合には、その輸液により所定の 圧力が各開閉部材の基端側（テーパ面）にかかり、その圧力により各開閉部材が離 間する方向に変位し、逆流防止弁 49内の流路が開通する。これにより、輸液は、基 端側から先端側に流れる。  [0149] On the other hand, when the infusion flow is directed from the proximal end side to the distal end side, a predetermined pressure is applied to the proximal end side (tapered surface) of each opening / closing member by the infusion solution, and the pressure causes each opening / closing member to move. Displacement is made in the direction of separation, and the flow path in the check valve 49 is opened. As a result, the infusion flows from the proximal side to the distal side.
[0150] 逆流防止弁 49は、輸液ポンプなどによって注入が確実な場合には無くとも良い場 合もある力 設置されていることがより好ましい。この第 2の輸液チューブ 4aによれば 、第 2の輸液チューブ 4aのコネクタ 5Aに接続された第 1の輸液チューブ 4bからある 程度の圧力を加えて輸液を投与しても、逆流防止弁 49により、その輸液が第 2の輸 液チューブ 4aの上流側（基端側）へ流れ込むのを防止することができ、確実に、輸液 を患者へ投与することができる。  [0150] It is more preferable that the backflow prevention valve 49 is provided with a force that may not be necessary when the injection is ensured by an infusion pump or the like. According to the second infusion tube 4a, even if an infusion is applied by applying a certain pressure from the first infusion tube 4b connected to the connector 5A of the second infusion tube 4a, the backflow prevention valve 49 Therefore, the infusion can be prevented from flowing into the upstream side (base end side) of the second infusion tube 4a, and the infusion can be surely administered to the patient.
[0151] 図 13に示すように、輸液投与部 2は、患者の血管 110に留置される留置針または カテーテル (本実施形態では、留置針 21)と、この留置針またはカテーテル (本実施 形態では、留置針 21)の基端部に接続された輸液投与部側コネクタ 26とを有してい  [0151] As shown in FIG. 13, the infusion administration unit 2 includes an indwelling needle or catheter (in this embodiment, indwelling needle 21) placed in the blood vessel 110 of the patient, and this indwelling needle or catheter (in this embodiment). An infusion needle connector 26 connected to the proximal end of the indwelling needle 21)
[0152] 留置針 21 (またはカテーテル）の構成材料としては、留置する部位によっては、翼 付静注針など金属の針のものでもよいが、好ましくは可撓性を有する高分子材料、例 えば、ポリエチレン、ポリプロピレン等のポリオレフイン、ポリエステル、ポリウレタン等 の熱可塑性樹脂等が挙げられる。 [0152] The constituent material of the indwelling needle 21 (or catheter) may be a metal needle such as a winged intravenous injection needle depending on the indwelling site, but is preferably a flexible polymer material, for example, Polyolefins such as polyethylene and polypropylene, and thermoplastic resins such as polyester and polyurethane.
[0153] 輸液投与部側コネクタ 26は、第 2の輸液チューブ 4aが接続されているコネクタ 5A のオスロック部 8Aおよびォスコネクタ部 6とそれぞれ接続し得るメスロック部 9Aおよび メスコネクタ部 7Aと、これらと同様のメスロック部 9Bおよびメスコネクタ部 7Bと、ォスコ ネクタ部 263とを有して!/、る。 [0153] The infusion administration side connector 26 has a female lock part 9A and a female lock part 9A that can be connected to the male lock part 8A and the male connector part 6 of the connector 5A to which the second infusion tube 4a is connected, respectively. It has a female connector portion 7A, a female lock portion 9B and a female connector portion 7B similar to these, and a male connector portion 263.
[0154] また、ォスコネクタ部 263の軸と、メスコネクタ部 7Aの軸とは、略一致し、メスコネクタ 部 7Bの軸は、これらの軸と略直交している。すなわち、ォスコネクタ部 263と、メスコ ネクタ部 7Aとは、互いに反対方向を向いており、メスコネクタ部 7Bは、これらォスコネ クタ部 263およびメスコネクタ部 7Aに対し、略垂直な方向を向いて!/、る。  [0154] Further, the axis of the male connector portion 263 and the axis of the female connector portion 7A substantially coincide with each other, and the axis of the female connector portion 7B is substantially orthogonal to these axes. That is, the male connector portion 263 and the female connector portion 7A face in opposite directions to each other, and the female connector portion 7B faces in a direction substantially perpendicular to the male connector portion 263 and the female connector portion 7A! / RU

A holding means for holding a temporarily fixed state in which the positional relationship between the first connector and the second connector is temporarily fixed is provided. Therefore, when there is a temporary fixing member, that is, when there is a temporary fixing member, the first connector and the second connector in the lock ready state are temporarily fixed (the temporarily fixed state is maintained). On the other hand, when there is no temporary fixing member, the first connector and the second connector are not ready for locking. Thus, it is possible to determine whether or not the first connector and the second connector are in the lock ready state by the presence or absence of the temporary fixing member. That is, the presence of the temporary fixing member makes it possible to reliably recognize that the first connector and the second connector are in the lock ready state. Therefore, the temporary fixing member of the present invention has industrial applicability.
