【０００１】
【発明の属する技術分野】
本発明は例えば輸液セット、採血セット、輸血セット、体外循環回路等の医療器具の途中に配置される混注部材、薬剤（輸液、生理食塩水溶液、血液保存液等）を封入した医薬容器に装着される口部及び医薬容器に接続されたチューブの途中に配置される混注部材であって、これらの医療器具及び医薬容器に薬剤を混注もしくは採取したり、又は血液を採取もしくは注入する時に使用される混注部材及び口部の改良に関する。
【０００２】
【発明が解決しようとする課題】
血液を患者の体内に入れる輸血治療、血液を体外に抜き出す採血検査等、薬剤を患者の体内に入れる輸液治療、または患者の体内から血液を一時的に抜き出す体外循環治療等を行なう際に、血液や薬剤を患者に注入したり採取する器具（例えば輸血セット、輸液セット、体外循環回路、採血セットなど）がある。
輸血セット、輸液セット、体外循環回路、採血セットなどを構成するラインの途中には、数々の構成部材が装着されているが、混注部材は血液を追加したり、検査のために血液を採取したり、また薬剤の追加や緊急時の薬剤投与など重要な役割を果たしている。
【０００３】
通常これらの混注部材は、管状の本体に突設された胴部に栓体が装着され、前記栓体には中央が開口したキャップが冠着されている。
使用に際しては、キャップの中央開口部に露出した栓体の天面に、先端が鋭利な金属製の針を穿刺し、針の後方に装着された容器の内部に封入されている薬剤や血液の注入または空の容器内に血液の採取を行なう。また、持続的な薬剤や血液の注入の場合、針の後方に薬剤や血液の入った容器と連通された延長チューブまたは輸液セット、輸血セットなどがある。その際混注部材に穿刺した針が抜け落ちないよう、粘着テープで混注部材と針基を固定することもある。
使用する針は、従来より先端が鋭利な金属針を使用する事が多かったが、作業者が金属針の先端に触れ、外傷だけでなく感染症に感染する危険が大きいく、近年、先端が鋭利な金属針に代えて、先端に丸みを帯びた形状を有する穿刺部材を使用する方法が考案されている。
先端に丸みを帯びた形状を有する穿刺部材（以下「穿刺部材」と略記する）を混注部材に穿刺する際に栓体天面にスリットを入れて刺通抵抗を低くして、刺し易くする試みがある。
スリットを入れる事により穿刺のきっかけができ、刺通抵抗が低くなり刺し易くなるが、先端が丸みを帯びた分スリットが拡大して穿刺跡が大きくなり、穿刺部材を引き抜いた後、血液や薬剤の液漏れが発生する虞がある。また、スリットを入れたことにより穿刺部材が抜け易くなる虞がある。
そこで、本発明者は以上の課題を解決するために鋭意検討を重ねた結果、次の発明に到達した。

【０００５】
【発明の実施の形態】
以下混注部材について薬剤の混注を行なう場合の一例について説明する。図１は参考例の混注部材１の平面図で、図２は図１の混注部材１の締付部材７に装着したハンドル４を回転させ、栓体５を締付けた時の混注部材１の平面図である。図３は図１の断面図で、図４（ハンドル４は、ネジ溝１０、ネジ山１１と重なるので省略した。）は図２の断面図である。混注部材１は管状の本体２の天面に突設された管状の胴部３に、弾性を有し且つ少なくとも天面にスリット６を形成した栓体５を装着し、前記胴部３の外周にはネジ溝１０とネジ山１１が螺旋状に形成され、前記ネジ溝１０に嵌合する凸部９を底部に形成し、且つ一対の板状のハンドル４を両側部にした締付部材７を、前記胴部３に装着する事により構成されている。また図１において締付部材７は天面の中央部が開口された筒状の締付部材で、栓体５の天上側面から胴部３の外周に亘って装着されている。
【０００６】
栓体５が何もなされてない状態（緩んだ状態）では、前記締付部材７のハンドル４は、管状の本体２と重なるように配置される。
また本体２の側壁には、本体２が指で挾持できるように円形の鍔８が設けられてる。
胴部３の外周に装着した締付部材７の両側部に設けたハンドル４を、図２のように時計方向に９０度回転することで、栓体５は前記締付部材７により胴部３の外周から締付けられ、スリット６も同時に締付けられる。
締付けた状態を再び緩める場合は、栓体７に設けたハンドル４を逆時計方向に９０度回転させる。
ハンドル４が本体２に対して９０度方向（１８０度、２７０度、３６０度、４５０度も含む。以下の発明の実施形態も同じ）に位置した時に締付力が最大限に達する様に、例えば胴部３に形成したネジ溝１０や前記締付部材７に設けられた凸部９の嵌合具合を設定する事ができる。
前記締付部材７や胴部３、栓体５やハンドル４の形状は図１に示したものに限定されず、要するに胴部３の外周から栓体５を締付けることのできる形状であれば何でも良く、ハンドル４と締付部材７を一体にして回動可能な形状であれば何でも良い。また鍔８を設ける位置は本体２の側面に限らず、本体２が指で挾持できるところであれば本体２の天面でもかまわない。
【０００７】
穿刺部材を混注部材１に穿刺する場合、締付部材７の開口部に露出した栓体５の天面のスリット６に前記穿刺部材を穿刺して、その先端を栓体５の底面を越えるまで貫通させる。
穿刺部材の後方に装着されたシリンジ内に封入されている薬剤を投与した後、穿刺部材を栓体５より引き抜いて、締付部材７に設けたハンドル４を時計方向に９０度回転させる事により締付部材７の上部から加圧され、栓体５のスリット６を締付ける事により、穿刺部材を引き抜いた跡を完全に締付けて液漏れを防ぐ事ができる。
栓体５の締付け具合は、締付部材７に設けられたハンドル４の方向で識別する事ができる。栓体５が何もなされてない状態（緩んだ状態）では前記ハンドル４は、管状の本体２と並行で重なるような位置になり、前記栓体５が締付けられた状態では、前記ハンドル４は管状の本体２と垂直に交わるような位置になる。
また、穿刺部材を穿刺し、シリンジに入れた薬剤等を持続的に投与する場合は、前記穿刺部材を穿刺したまま、締付部材７に設けたハンドル４を時計方向に９０度回転させ、前記と同様に栓体５のスリット６を締付ける事により穿刺部材を締付け、穿刺部材が抜け落ちないように固定することができ、更に穿刺部材とスリットの間から液漏れが無いようにする事ができる。
栓体５の締付け具合は、締付部材７に設けられたハンドル４の方向で識別する事ができる。栓体５が何もなされてない状態（緩んだ状態）では前記ハンドル４は、管状の本体２と並行で重なるような位置になり、前記栓体５が締付けられた状態では、前記ハンドル４は管状の本体２と垂直に交わるような位置になる。
【０００８】
図５は本発明の実施例の混注部材１Ａの側面図で、図６は混注部材１Ａの締付部材７ａに設けたハンドル４を回転させ、栓体５ａを締付けた時の混注部材１Ａの側面図である。締付部材７ａには、締付け具合を識別する為の窓状の表示部１２が正面と背面に二ヶ所設けられてる。胴部３には正面と背面に「緩む」、右と左両側面に「締る」の文字が付された栓体５ａが装着され、これらの文字は前記表示部１２の窓が回動する事により目視できる。栓体５ａの締付け具合は、窓状の表示部１２の表示により識別できる。栓体５ａが何もなされてない状態（緩んだ状態）では、図５のように正面と背面の表示部１２に「緩む」と表示される。他方、図６のようにハンドル４を時計方向に９０度回転させると、栓体５ａは締付部材７ａにより上から下に締付けられると同時に右と左両側面の窓状の表示部１２に「締る」と表示される。窓状の表示部１２を設けた識別表示は、締付部材７（７ａ）にハンドル４等を設けない場合に特に有益である。
【０００９】
図７はその他の発明の実施例を示す混注部材１Ｂの平面図で、図８は図７の混注部材１Ｂの締付部材７ｂに設けてるハンドル４ａを回転させ、栓体５を締付けた時の混注部材１Ｂの平面図である。図９は図７の側面図で、図１０は図８の側面図である。混注部材１Ｂは管状の本体２の天面に突設された管状の胴部３に弾性を有し且つ少なくとも天面にスリット６を形成した栓体５を装着し、前記胴部３の外周にはネジ溝１０とネジ山１１が螺旋状に形成され、前記ネジ溝１０に嵌合する凸部９を底部に形成した締付部材７ｂを前記胴部３に装着する事により構成されている。また図７において締付部材７ｂは天面の中央部が開口された筒状の締付部材で、栓体５の天上側面から胴部３の外周に亘って装着されている。本体２の側壁には、胴部３を中心に一対の扇状の表示板１３が形成され、締付部材７ｂには両側部に一対の板状ハンドル４ａと底部に一対の扇状の回転板１４が装着されている。
【００１０】
栓体５が何もなされてない状態（緩んだ状態）では、図７のように回転板１４は前記表示板１３の識別表示部分と重ならない部分に位置すると同時に、ハンドル４ａは管状の本体２と並行な位置にあるので、表示板１３の識別標識（例えば着色、文字等）が表示される。
他方、締付部材７ｂの側面に設けたハンドル４ａを時計方向に９０度回転させると栓体５は、締付部材７ｂにより上から下に締付けられ、スリット６も同時に締付けられる。この時図８に示すように回転板１４も９０度回転し表示板１３の上に重なるので表示板１３の識別表示部分は隠れてしまう。
締付けた状態を再び緩める場合は、回転板１４に設けたハンドル４ａを逆時計方向に９０度回転させる。
ハンドル４ａが本体２に対して９０度方向（１８０度、２７０度、３６０度、４５０度も含む。以下の発明の実施形態も同じ）に位置した時に締付力が最大限に達する時に、例えば表示板１３の識別表示部分が回転板１４で隠れる状態にし、胴部３に形成したネジ溝１０や締付部材７ｂに設けられた凸部９の嵌合具合を、設定する事ができる。
前記締付部材７ｂや胴部３、栓体５やハンドル４ａ、表示板１３や回転板１４の形状は図に示したものに限定されず、要するに胴部３の外周から栓体５を締付けることのできる形状であれば何でも良く、締付け具合が識別表示できる回転可能な形状であれば何でも良い。従ってハンドル４ａは必要としない場合も有り得る。また前記表示板１３と前記回転板１４もそれぞれ一対（二箇所）設ける必要はなく締付け具合を識別表示できれば、それぞれ最低一箇所設けるのみで良い。
【００１１】
穿刺部材を混注部材１Ｂに穿刺する場合、締付部材７ｂの開口部に露出した栓体５天面のスリット６に前記穿刺部材を穿刺して、その先端を栓体５の底面を越えるまで貫通させる。
穿刺部材の後方に装着されたシリンジ内に封入されている薬剤を投与した後、穿刺部材を栓体５より引き抜いて、締付部材７ｂに設けたハンドル４ａを時計方向に９０度回転させる事により、締付部材７ｂの上部から加圧され、栓体５のスリット６を締付ける事により、穿刺部材を引き抜いた跡を完全に締付けて液漏れを防ぐ事ができる。
同時に回転板１４が回転し、表示板１３の識別表示部分と重なり、識別表示は隠れてしまう。
栓体５が何もなされてない状態（緩んだ状態）では、回転板１４は前記表示板１３と重ならない部分に位置すると同時に、ハンドル４ａは管状の本体２と並行な位置にあるので表示板１３の識別標識が表示される。他方栓体５が締付けられた状態では、回転板１４が表示板１３の識別表示部分と重なり、ハンドル４ａは管状の本体２と垂直に交わるような位置にあるので識別表示は隠れる。
また、穿刺部材を穿刺し、シリンジに入れた薬剤等を持続的に投与する場合は、前記穿刺部材を穿刺したまま、締付部材７ｂに設けたハンドル４ａを時計方向に９０度回転させ、前記と同様に栓体５のスリット６を締付ける事により穿刺部材を締付け、穿刺部材が抜け落ちないように固定することができ、更に穿刺部材とスリットの間から液漏れが無いようにする事ができる。
同時に回転板１４が回転し表示板１３の識別表示部分と重なり、識別表示は隠れてしまう。
栓体５が何もなされてない状態（緩んだ状態）では、回転板１４は前記表示板１３と重ならない部分に位置すると同時に、ハンドル４ａは管状の本体２と並行な位置にあるので表示板１３の識別標識が表示される。他方栓体５が締付けられた状態では、回転板１４が表示板１３の識別表示部分と重なり、ハンドル４ａは管状の本体２と垂直に交わるような位置にあるので識別表示は隠れる。
【００１２】
図１１は前記胴部３に代えて、その他の発明の実施例を示す混注部材１Ｃの断面図で、図１２は図１１の混注部材１Ｃの締付部材７に設けたハンドル４を回転させ、栓体５ｂを締付けた時の混注部材１Ｃの断面図である。（ハンドル４は、ネジ溝１０、ネジ山１１と重なるので省略した。）混注部材１Ｃは管状の本体２の天面に突設された管状の前記胴部３に代えて胴部３ａを配置したものである。該胴部３ａは弾性を有し且つ少なくとも天面にスリット６を形成した栓体５ｂを装着し、下部から上部に向けて若干ではあるが大径になるように形成され、外周壁には少なくとも一箇所以上好ましくは二箇所以上のＶ形切り込み部１５を設け、且つネジ溝１０の深さを上部から下部にかけて次第に浅く形成されている。また図１１において締付部材７は天面の中央部が開口された筒状の締付部材で、栓体５ｂの天上側面から胴部３ａの外周に亘って装着されている。胴部３ａの外周に装着した締付部材７の両側部に設けたハンドル４を図１２のように時計方向に９０度回転させることで、栓体５ｂは前記胴部３ａを介して締付部材７により締付けられる。同時に前記胴部３ａの外周に形成されたＶ形切り込み部１５は、締付部材７を下に回動することにより前記胴部３ａの上部より下部方向にかけて前記胴部３ａの外周を締付ける力が強く作用するので図１２のように閉じられる。締付けた状態を再び緩める場合は、栓体７に設けたハンドル４を逆時計方向に９０度回転させる。ハンドル４が本体２に対して９０度方向（１８０度、２７０度、３６０度、４５０度も含む。以下の発明の実施形態も同じ）に位置した時が締付力が最大限に達する様に、例えば胴部３ａに形成されるネジ溝１０や前記締付部材７に設けられた凸部９の嵌合具合を設定する事ができる。前記胴部３ａの内径は、下部から上部に向けて若干ではあるが大径になるように形成されているが、締付部材７や栓体５ｂやハンドル４の形状は図１１に示したものに限定されず、要するに胴部３ａの外周から栓体５ａを締付けることのできる形状であれば何でも良く、ハンドル４と締付部材７を一体にして回動可能な形状であれば何でも良い。
【００１３】
図１３は図１１の混注部材１Ｃのその他の発明の実施例を示す混注部材１Ｄである。
混注部材１Ｄは、前記胴部３ａに代えて、内径と外径を均一にし、ネジ溝１０の深さも均一に形成した胴部３ｂを装着し、前記栓体５ｂに代えて、中腹部に溝部１６を設けた栓体５ｃを装着し、更に前記締付部材７に代えて、底部に凸部９と中腹部に凸部９ａを形成した締付部材７ｃを配置している。
前記締付部材７ｃの底部の凸部９と中腹部の凸部９ａの長さは、中腹部の凸部９ａの方が長く形成され、前記凸部９は、胴部３ｂに設けられた溝部１０と嵌合し、前記中腹部の凸部９ａは、前記栓体５ｃに形成された溝部１６と嵌合されている。
前記締付部材７ｃは天面の中央部が開口された筒状の締付部材で、栓体５ｃの天上側面から胴部３ｂの外周に亘って装着されている。
前記胴部３ｂの外周に装着した締付部材７ｃの両側部に設けたハンドル４を時計方向に９０度回転させることで、栓体５ｃは前記胴部３ｂを介して締付部材７ｃにより締付けられる。同時に前記胴部３ｂの外周に形成されたＶ形切り込み部１５は、締付部材７ｃを下に回動することにより、前記締付部材７ｃの中腹部の凸部９ａが前記胴部３ｂの外周から内側に深く食い込むことにより閉じられる。
同時に底部の凸部９も前記胴部３ｂと栓体５ｂを外周から締付ける。（図１３の混注部材１Ｄのハンドル４を時計方向に９０度回転させ、栓体５ｃを前記胴部３ｂを介して締付部材７ｃにより締付けた図は省略する。）
【００１４】
図１４は図１３の混注部材１Ｄのその他の発明の実施例を示す混注部材１Ｅである。

BACKGROUND OF THE INVENTION
The present invention is, for example, mounted on a pharmaceutical container enclosing a mixed injection member disposed in the middle of a medical device such as an infusion set, a blood collection set, a transfusion set, an extracorporeal circuit, and a medicine (infusion solution, physiological saline solution, blood preservation solution, etc.). This is a mixed injection member placed in the middle of the mouth part and the tube connected to the pharmaceutical container, and is used when mixing or collecting a drug in these medical instruments and pharmaceutical containers, or collecting or injecting blood The present invention relates to improvement of a mixed injection member and a mouth portion.
[0002]
[Problems to be solved by the invention]
When performing blood transfusion treatments that introduce blood into the patient's body, blood sampling tests that extract blood outside the body, fluid treatments that introduce drugs into the patient's body, or extracorporeal circulation treatments that temporarily remove blood from the patient's body, etc. And devices for injecting and collecting drugs into patients (eg, blood transfusion set, infusion set, extracorporeal circuit, blood collection set, etc.).
A number of components are installed in the middle of the lines that make up a transfusion set, infusion set, extracorporeal circuit, blood collection set, etc., but mixed injection members add blood or collect blood for testing. It also plays important roles such as adding drugs and administering drugs in emergencies.
[0003]
Normally, these co-infusion members are fitted with a plug body on a body portion protruding from a tubular main body, and a cap with an open center is attached to the plug body.
In use, a metal needle with a sharp tip is punctured on the top surface of the stopper exposed at the central opening of the cap, and the medicine or blood sealed inside the container attached to the back of the needle Blood is collected by injection or in an empty container. In the case of continuous infusion of medicine or blood, there are an extension tube, an infusion set, a transfusion set, or the like communicated with a container containing the medicine or blood behind the needle. At that time, the mixed injection member and the needle base may be fixed with an adhesive tape so that the needle punctured into the mixed injection member does not fall off.
The needle used is often a metal needle with a sharper tip than before, but the operator touches the tip of the metal needle and there is a greater risk of not only trauma but also an infection. A method of using a puncture member having a rounded shape at the tip instead of a sharp metal needle has been devised.
Attempting to make the piercing member easier to pierce by making a slit in the top surface of the plug body to puncture a mixed injection member with a puncture member having a rounded tip (hereinafter abbreviated as “puncture member”). There is.
By inserting a slit, puncture can be triggered and puncture resistance is lowered and puncture is facilitated, but the tip is rounded and the slit expands to enlarge the puncture mark, and blood and medicine are extracted after the puncture member is pulled out. There is a risk of liquid leakage. Moreover, there is a possibility that the puncture member can be easily removed by inserting the slit.
Therefore, as a result of intensive studies to solve the above problems, the present inventor has reached the following invention.
