Injection tube ST is formed of a continuous tube that is seamless from the base end PE side to the terminal DE side. The integrally formed communicating member 211 is inserted on the proximal end PE side of the injection tube ST.
図９（Ａ）、（Ｂ）、図１０（Ｂ）の従来の液体注入部品１０１では、
（ａ）注入チューブ全体（第１注入チューブＳＴ１〜第３注入チューブＳＴ３）中への液体のプライミングボリームが多くなる点。
（ｂ）各部品間に（接続）段差が多くできる点。
（ｃ）部品点数が多く、かつ各部品の接続の手間がかかり製造コストが高くなる点である。
図１０（Ａ）の特許文献１の液体注入部品１０１では、
前記（ａ）〜（ｃ）の課題は解決されたが、短時間で液体の流量を多く確保したい場合は、
（ｄ）注入チューブＳＴの内径が細く、切断部２０１の外径と注入チューブＳＴの内径の差（間隔）が小さいため、困難な場合がある。
In the conventional liquid injection component 101 in FIGS. 9A, 9B, and 10B,
(A) The priming volume of liquid into the entire injection tube (first injection tube ST1 to third injection tube ST3) increases.
(B) There are many (connection) steps between the parts.
(C) The number of parts is large, and it takes time and labor to connect each part, resulting in high manufacturing costs.
In the liquid injection component 101 of Patent Document 1 in FIG.
Although the problems (a) to (c) have been solved, when it is desired to secure a large liquid flow rate in a short time,
(D) Since the inner diameter of the injection tube ST is thin and the difference (interval) between the outer diameter of the cutting portion 201 and the inner diameter of the injection tube ST is small, it may be difficult.

[Liquid injection part 1]
As illustrated in FIGS. 1 to 3, the liquid injection component 1 of the present invention includes a communication member 11, a connection member 21, and a connection pipe 40.
[Communication member 11]
As illustrated in FIGS. 1 to 2, the communication member 11 includes a cutting portion 12 on the terminal DE side and a fixing portion 13 on the proximal end PE side.
The cutting portion 12 is formed in a so-called “saddle shape” (or may be a rod shape or a plate shape), and the fixing portion 13 is formed in a so-called “tubular shape”. In the illustration of FIG. 1, the cutting part 12 is formed in a so-called “substantially plate shape”.
切断部１２は、長手方向に沿うように、側部Ｓ方向（外周ないし外周の一部）に突部１２Ｔを突設している。切断部１２の断面は、いわゆる「長方形（矩形）状」に形成している。
突部１２Ｔは、例えば側部方向（長辺の表と裏）に、１８０°対向して、二箇所形成している。
切断部１２の短辺（側部Ｓ方向の外径１２Ｄ、幅という場合もある）は、固定部１３の外径よりも小さく形成している。突部１２Ｔは、末端ＤＥ側に下る方向にテーパ（図１参照）を形成している。
The cutting portion 12 has a protruding portion 12T protruding in the side S direction (outer periphery or part of the outer periphery) along the longitudinal direction. The cross section of the cutting part 12 is formed in a so-called “rectangular shape”.
The protrusions 12T are formed at two locations, for example, 180 ° opposite each other in the side direction (the front and back of the long side).
The short side of the cutting part 12 (the outer diameter 12D in the side part S direction, sometimes referred to as the width) is formed smaller than the outer diameter of the fixing part 13. The protrusion 12T forms a taper (see FIG. 1) in a direction descending to the terminal DE side.
固定部１３は末端ＤＥ側で切断部１２の基端ＰＥ側と一体に接続（一体成形）している。
固定部１３の末端ＤＥ側の壁は、固定部１３の末端ＤＥ側と切断部１２の基端ＰＥ側との間の段部１１Ｄを形成する。固定部１３の末端ＤＥ側の壁を以下、「段部１１Ｄ」という。
固定部１３の末端ＤＥ側と切断部１２の基端ＰＥ側との間に切断領域１４を形成している。
切断領域１４とは図１（Ａ）（Ｂ）に例示するように、固定部１３の末端ＤＥ側と切断部１２の基端ＰＥ側の側部Ｓ（外周）方向に形成した溝１４Ｍで、側部Ｓ（外周）方向の壁を薄肉部１４Ｗに形成した箇所である。
The fixed portion 13 is integrally connected (integrated molding) with the proximal end PE side of the cutting portion 12 on the terminal DE side.
The wall on the terminal DE side of the fixing part 13 forms a step part 11D between the terminal DE side of the fixing part 13 and the base PE side of the cutting part 12. Hereinafter, the wall on the terminal DE side of the fixing portion 13 is referred to as a “step portion 11D”.
A cutting region 14 is formed between the terminal DE side of the fixing part 13 and the base end PE side of the cutting part 12.
As illustrated in FIGS. 1A and 1B, the cutting region 14 is a groove 14M formed in the direction of the side S (outer periphery) on the terminal DE side of the fixing portion 13 and the base end PE side of the cutting portion 12, This is a place where the wall in the side portion S (outer periphery) direction is formed in the thin portion 14W.
[接続部材２１]
接続部材２１は、図１〜図２に例示するようにいわゆる「管状」に形成し、第１側部Ｓ１側と第２側部Ｓ２側にいわゆる「翼状」の突起部２２を突設し、基端ＰＥ側の側部Ｓ方向（外周ないし外周の一部）に接続部２３を突設している。
翼状の突起部２２は、略長方形（矩形）状に形成され、第１側部Ｓ１側と第２側部Ｓ２側の方向に「短辺」、長手Ｌ方向に「長辺」を有する。
接続部２３は、図１の例示ではいわゆる「螺子部」であり、他の医療用具（前記段落［０００１］の記載参照）、これら医療用具の付属品（液体容器、シリンジ等の接続部、コネクタ等）と接続できるように形成したものである。
[Connecting member 21]
The connection member 21 is formed in a so-called “tubular” as illustrated in FIG. 1 to FIG. 2, and so-called “wing-like” protrusions 22 project from the first side S1 side and the second side S2 side, A connecting portion 23 is projected in the side S direction (outer periphery or part of the outer periphery) on the base end PE side.
The wing-shaped protrusion 22 is formed in a substantially rectangular shape (rectangular shape), and has a “short side” in the direction on the first side S1 side and the second side S2 side, and a “long side” in the longitudinal L direction.
In the illustration of FIG. 1, the connection portion 23 is a so-called “screw portion”, and other medical devices (see the description in the paragraph [0001]), accessories of these medical devices (connection portions such as liquid containers and syringes, connectors, and the like) Etc.).
図１の例示では螺子部であるが、他の医療用具の接続部の形態（オス型コネクタ、メス型コネクタ）にあわせて、オス型の突起部、メス型の溝部（凹部）等にすることもできる。
翼状の突起部２２は、接続部２１の径Ｄの大きさを、「１００」とすると、大きさＳＬ（第１側部Ｓ１、第２側部Ｓ２の側部方向に突設した「短辺」の長さ、大きさ）を「４０〜１００」に形成している。
さらに翼状の突起部２２は、第１側部Ｓ１、第２側部Ｓ２の側部方向（「短辺」）に、ウエブ２２Ｗ（水かき、または板状部材、または補強部材、または掛止部材ともいう）を複数形成している。図１、図２の例示では、第１側部Ｓ１と第２側部Ｓ２方向にそうようにそれぞれ三箇所対抗して第３側部方向と第４側部方向に突設している。
Although it is a screw part in the illustration of FIG. 1, according to the form (male connector, female connector) of the connection part of another medical device, it is set as a male type projection part, a female type groove part (concave part), etc. You can also.
When the diameter D of the connecting portion 21 is “100”, the wing-like protruding portion 22 has a size SL (“short side protruding in the direction of the side of the first side portion S1 and the second side portion S2”. "Length and size" are formed to be "40 to 100".
Further, the wing-like protrusion 22 is a web 22W (water web, plate-like member, reinforcing member, or latching member) in the side direction ("short side") of the first side portion S1 and the second side portion S2. Multiple). In the illustration of FIG. 1, FIG. 2, it protrudes in the 3rd side part direction and the 4th side part direction so as to oppose three places respectively so that it may be in the 1st side part S1 and 2nd side part S2.
連通部材１１のほうからみれば、翼状の突起部２２は、グリップの役割を果たすので、連通部材１１の固定部１３を持ちやすくなる。さらに前記複数のウエブ２２Ｗに、指を引っかけることができる。これらにより連通部材１１の切断部１３に、外から力を加えやすく、切断しやすくなる。
接続部材２１のほうからみても、翼状の突起部２２はグリップの役割を果たすので、持ちやすく、接続部材２１に装着するキャップ２１ＣＰ（図３（Ｂ）参照）の開閉操作がしやすい。
When viewed from the communication member 11, the wing-like protrusion 22 plays a role of a grip, so that the fixing portion 13 of the communication member 11 is easily held. Furthermore, a finger can be hooked on the plurality of webs 22W. Accordingly, it is easy to apply a force from the outside to the cutting portion 13 of the communication member 11 and it is easy to cut.
Even when viewed from the connection member 21, the wing-like protrusion 22 serves as a grip, so it is easy to hold and the cap 21 </ b> CP (see FIG. 3B) attached to the connection member 21 can be easily opened and closed.
さらに、連通部材１１の固定部１３と接続部材２１との間に翼状の突起部２２がある（存在する）ことにより、キャップ２１ＣＰを開放する時に、勢い余って、同時に連通部材１１の切断部１２を折ってしまうような誤操作が懸念されるがあるが、このような誤操作のリスクを解消することができる。
なお連通部材１１の固定部１３と接続部材２１との間の翼状の突起部２２がない場合、（または翼状の突起部２２の大きさＳＬが小さすぎる場合）キャップを開閉する時に、誤って、同時に連通部材１１の切断部を折ってしまうような誤操作が懸念される。
Further, since the wing-like protrusion 22 is present (existing) between the fixing portion 13 of the communication member 11 and the connection member 21, when the cap 21CP is opened, the cutting portion 12 of the communication member 11 is simultaneously surplus. Although there is a concern about erroneous operations that would cause the user to break, the risk of such erroneous operations can be eliminated.
In addition, when there is no wing-like projection 22 between the fixed portion 13 of the communication member 11 and the connection member 21 (or when the size SL of the wing-like projection 22 is too small), when opening and closing the cap, At the same time, there is a concern about an erroneous operation that breaks the cut portion of the communication member 11.
翼状の突起部２２の大きさＳＬは、４０〜１００が好ましく、５０〜９０、６０〜８０がより好ましい。
翼状の突起部２２の大きさＳＬがあまり小さいと、前記効果を発揮しずらく好ましくない。逆に翼状の突起部２２の大きさＳＬがあまり大きいと、嵩張りすぎて操作を阻害するので好ましくない。
40-100 are preferable and, as for size SL of the wing-like projection part 22, 50-90 and 60-80 are more preferable.
If the size SL of the wing-like protrusion 22 is too small, it is not preferable because the effect is difficult to be exhibited. Conversely, if the size SL of the wing-like projection 22 is too large, it is not preferable because it is too bulky and hinders the operation.
接続部材２１の末端ＤＥ側は、連通部材１１の固定部１３の基端ＰＥ側と一体に接続（一体成形）している。
接続部材２１の末端ＤＥ側の壁は、接続部材２１の末端ＤＥ側と連通部材１１の固定部１３の基端ＰＥとの間に段部１１Ｄを形成している。接続部材２１の末端ＤＥ側の壁を以下、「段部１１Ｄ」という。
The terminal DE side of the connection member 21 is integrally connected (integrated molding) with the base end PE side of the fixed portion 13 of the communication member 11.
The wall on the terminal DE side of the connecting member 21 forms a step portion 11D between the terminal DE side of the connecting member 21 and the base end PE of the fixing portion 13 of the communication member 11. The wall on the terminal DE side of the connecting member 21 is hereinafter referred to as “step portion 11D”.
［接続管４０］
接続管４０は、図２に例示するように、基端ＰＥ側から末端ＤＥ側からにわたって、
大径部４０Ｂ、中間部４０Ｍ、細径部４０Ｓ、フランジ４０Ｆ及び接続部４０Ａを連続して一体に形成している。
これらの径の大きさは、大きいほうから、大径部４０Ｂ＞中間部４０Ｍ＞フランジ４０Ｆ＞細径部４０Ｓ＞接続部４０Ａの順となっている。
または大きいほうから、大径部４０Ｂ＞中間部４０Ｍ＝フランジ４０Ｆ＞細径部４０Ｓ＝接続部４０Ａの順となっている。
「大径部４０Ｂ」は、接続管４０の中で最も大きい径に形成されている部分である。
前記連通部材１１を挿入して、収納する部分である。
「中間部４０Ｍ」は、大径部４０Ｂが細径部４０Ｓへ移行する部分で、末端ＤＥ側へ下るテーパ状に形成している。内部（内周）は段部４０Ｄ（液体の流れる方向に傾斜しているテーパ）となっている。
[Connection pipe 40]
As illustrated in FIG. 2, the connecting pipe 40 extends from the base end PE side to the terminal DE side.
The large-diameter portion 40B, the intermediate portion 40M, the small-diameter portion 40S, the flange 40F, and the connecting portion 40A are integrally formed continuously.
The sizes of these diameters are, in descending order, large diameter portion 40B> intermediate portion 40M> flange 40F> small diameter portion 40S> connection portion 40A.
Or, from the larger one, the large diameter portion 40B> the intermediate portion 40M = the flange 40F> the small diameter portion 40S = the connecting portion 40A.
The “large diameter portion 40 </ b> B” is a portion formed in the connecting pipe 40 with the largest diameter.
The communication member 11 is inserted and stored.
The “intermediate portion 40M” is a portion where the large-diameter portion 40B moves to the small-diameter portion 40S, and is formed in a tapered shape that goes down to the terminal DE side. The inside (inner circumference) is a stepped portion 40D (taper that is inclined in the liquid flow direction).
「細径部４０Ｓ」は、中間部４０Ｍから末端ＤＥ側へ延設している部分である。細径部４０Ｓは末端ＤＥから基端ＰＥの間に、鉗子（クランプ）ＣＬを装着して、液体流路を閉塞することができる。
細径部４０Ｓの末端ＤＥ側（フランジ４０Ｆ側）は、図７に示すように鉗子（クランプ）ＣＬで、液体流路を閉塞しやすいように、いわゆる「湾曲部Ｒ」（アール部ともいう）を形成している。図２（Ａ）、（Ｂ）参照。
The “small diameter portion 40S” is a portion extending from the intermediate portion 40M toward the terminal DE side. The small diameter portion 40S can close the liquid flow path by attaching a forceps (clamp) CL between the terminal DE and the base PE.
The distal DE side (flange 40F side) of the small-diameter portion 40S is a so-called “curved portion R” (also referred to as a round portion) so that the liquid flow path can be easily closed with forceps (clamp) CL as shown in FIG. Is forming. See FIGS. 2A and 2B.
なお図１０（Ａ）の特許文献１に記載の発明では、注入チューブＳＴの外部から鉗子（クランプ）ＣＬを装着して、液体流路を閉塞していたが、注入チューブＳＴの中を切断部材２１２が浮遊している箇所に、鉗子（クランプ）ＣＬが当たると液体流路は閉塞しにくいとういう操作上の難点があった。
図９、図１０（Ｂ）の液体注入部品１０１の場合も同様の操作上の難点があった。
すなわち第１注入チューブＳＴ１、第３注入チューブＳＴ３は別部品として細径に形成し、段差のある接続をしているので、鉗子（クランプ）ＣＬを外部から装着してクランプできない。無理に装着すると接続箇所の破壊の原因となる。第２注入チューブＳＴ２に鉗子（クランプ）ＣＬを外部から装着してクランプすることになる。
In the invention described in Patent Document 1 in FIG. 10A, forceps (clamps) CL are attached from the outside of the injection tube ST to close the liquid flow path. When the forceps (clamp) CL hits the place where 212 is floating, there is an operational difficulty that the liquid flow path is not easily blocked.
In the case of the liquid injection component 101 of FIGS. 9 and 10B, there are similar operational difficulties.
That is, since the first injection tube ST1 and the third injection tube ST3 are formed as separate parts with a small diameter and are connected with a step, the forceps (clamp) CL cannot be attached and clamped from the outside. If attached forcibly, it may cause damage to the connection. A forceps (clamp) CL is attached to the second injection tube ST2 from the outside and clamped.
「接続部４０Ａ」は、分岐管３０の第３管部３３と接続する部分である。
「フランジ４０Ｆ」は、接続部４０Ａを分岐管３０の第３管部３３に接続するときのストッパーとなり、鉗子（クランプ）ＣＬを細径部４０Ｓに装着したときのストッパーともなる。
The “connecting portion 40A” is a portion connected to the third pipe portion 33 of the branch pipe 30.
The “flange 40F” serves as a stopper when the connection portion 40A is connected to the third tube portion 33 of the branch tube 30, and also serves as a stopper when the forceps (clamp) CL is attached to the small diameter portion 40S.
連通部材１１は、図２（Ｂ）に例示するように、基端ＰＥ側から末端ＤＥ側からにわたって、接続管４０の大径部４０Ｂの（略中腹部から基端ＰＥ側にわたって）内部（内周）に挿入している。
さらにいえば、連通部材１１は、全ての長手方向の外周を接続管４０の基端ＰＥ側の
大径部４０Ｂの内部（内周）で覆っている。
接続管４０は、基端ＰＥ側の壁面が接続部材２１の段部１１Ｄに当接している。
接続部材２１は、全ての長手方向で接続管４０で覆われることなく、露出している。
As illustrated in FIG. 2 (B), the communication member 11 extends from the base end PE side to the terminal DE side, and inside (inside the substantially middle abdominal part to the base end PE side) of the large-diameter portion 40B of the connection pipe 40. Inserted around).
Furthermore, the communication member 11 covers all the outer circumferences in the longitudinal direction with the inside (inner circumference) of the large-diameter portion 40B on the proximal end PE side of the connection pipe 40.
In the connection pipe 40, the wall surface on the base end PE side is in contact with the step portion 11 </ b> D of the connection member 21.
The connecting member 21 is exposed without being covered with the connecting pipe 40 in all longitudinal directions.

４０ＢＳＬがあまり小さい（２００未満）と、十分な液体流路を広く確保できない。４０ＢＳＬがあまり大きい（３００を超える）と、部品全体が大きくなりすぎる。
2, the length (40BSL) of the space portion of the connecting pipe 40 (the length from the base end PE of the cutting portion 11 to the terminal DE of the large diameter portion 40B), the length of the cutting portion 12 in the longitudinal L direction. (12L). With respect to (12L): 100, (40BL): 200-300, preferably 230-250.
If 40BSL is too small (less than 200), a sufficient liquid flow path cannot be secured widely. If 40BSL is too large (greater than 300), the entire part becomes too large.
また切断部１２の側部Ｓ方向の径（１２Ｄ）、大径部４０Ｂの内径（４０ＳＩＤ）と規定する。
（１２Ｄ）：１００に対して、（４０ＳＩＤ）：１１０〜１５０、好ましくは１２０〜１３０に形成する。４０ＳＩＤがあまり小さい（１１０未満）と十分な液体流路を広く確保できない。あまり大きい（１５０を超える）と部品全体が大きくなりすぎる。
これにより、大径部４０Ｂ内で、切断部１２が液体の流れを阻害することはない。
液体を余裕を持って通過させることができる。
Moreover, it defines with the diameter (12D) of the side part S direction of the cutting part 12, and the internal diameter (40SID) of the large diameter part 40B.
(12D): 100, (40SID): 110-150, preferably 120-130. If 40SID is too small (less than 110), a sufficient liquid flow path cannot be secured widely. If it is too large (over 150), the entire part becomes too large.
Thereby, the cutting | disconnection part 12 does not inhibit the flow of a liquid within the large diameter part 40B.
The liquid can be passed with a margin.
図１（Ｂ）に例示するように、接続部材２１の基端ＰＥ側から末端ＤＥ側の内部壁面、連通部材１１の固定部１３の基端ＰＥ側から末端ＤＥ側の内部壁面へ向けて、下りテーパ２３Ｔ（接続部材２１の第２下りテーパ）、下りテーパ２２Ｔ（接続部材２１の第１下りテーパ）、下りテーパ１３Ｔ（連通部材１１の固定部１３の下りテーパ）を、緩やかな実質的に同一勾配（１／１００〜２／１００）で連続して形成している。
勾配は１／１００未満では、製造が困難である。２／１００を超えると下りテーパ１３Ｔ側の液体流路が狭くなる。
As illustrated in FIG. 1B, from the proximal end PE side of the connecting member 21 to the inner wall surface on the distal DE side, from the proximal end PE side of the fixing portion 13 of the communication member 11 to the inner wall surface on the distal DE side, The downward taper 23T (the second downward taper of the connection member 21), the downward taper 22T (the first downward taper of the connection member 21), and the downward taper 13T (the downward taper of the fixing portion 13 of the communication member 11) are gradually reduced. It forms continuously with the same gradient (1/100 to 2/100).
If the gradient is less than 1/100, it is difficult to manufacture. If it exceeds 2/100, the liquid channel on the downward taper 13T side becomes narrow.
さらに固定部１３の末端ＤＥ側の内径（１３ＩＤ）、切断部１１の径（１２Ｄ）で規定する。

（１３ＩＤ）はあまり小さい（９８未満）と、十分な液体流路を広く確保できない。あまり大きい（９８を超える）と、製造が困難となる。
これにより接続部材２１から連通部材１１の内部にわたって液体流路を広く確保している。
これにより接続部材２１の基端ＰＥ側から導入された液体を速やかに、連通部材１１の固定部１３の末端ＤＥ側へ流出させることができる。
Further, it is defined by the inner diameter (13ID) on the terminal DE side of the fixing part 13 and the diameter (12D) of the cutting part 11.
For (12D): 100, (13ID) is 90 to 98, preferably 93 to 96.
If (13ID) is too small (less than 98), a sufficient liquid flow path cannot be secured widely. If it is too large (exceeding 98), the production becomes difficult.
This ensures a wide liquid flow path from the connection member 21 to the inside of the communication member 11.
As a result, the liquid introduced from the base end PE side of the connection member 21 can quickly flow out to the terminal DE side of the fixing portion 13 of the communication member 11.
