Description

本発明は、バイアルなどの薬剤容器内に収容された粉末製剤や凍結乾燥製剤などの、使用時に溶解液に溶解混合するタイプの薬剤を、点滴投与する際の溶解混合手段を備える両頭針付き溶解液容器に関する。   The present invention relates to dissolution with a double-ended needle provided with a dissolution and mixing means for infusion administration of a drug that is dissolved and mixed in a dissolution liquid at the time of use, such as a powder preparation and a freeze-dried preparation contained in a drug container such as a vial. It relates to a liquid container.

従来から、病院等の医療機関において、バイアルなどの薬剤容器に収容された粉末製剤や凍結乾燥製剤などの薬剤は、生理食塩水、ブドウ糖液、または純水などの溶解液に溶解混合され、薬液として患者に点滴投与されている。
そこで、薬剤の溶解液への溶解混合操作を、容易かつ衛生的に行うことができる溶解液容器として、溶解液が収容された溶解液容器に、その溶解液容器と薬剤容器とを連通するための両頭針ユニットを装着した形態の、両頭針付き溶解液容器が開発されている。
しかし、従来の両頭針付き溶解液容器は、それを構成する部品数が多く、あるいは、製造方法が複雑であり、製造コストが高いという問題があった。
Conventionally, in medical institutions such as hospitals, drugs such as powder preparations and freeze-dried preparations stored in drug containers such as vials are dissolved and mixed in a solution such as physiological saline, glucose solution, or pure water. As a drip infusion to the patient.
Therefore, as a solution container that can be easily and hygienically dissolved and mixed with a drug solution, the solution container and the drug container are communicated with the solution container containing the solution. A double-headed lysate container with a double-ended needle unit has been developed.
However, the conventional solution container with a double-ended needle has a problem that it has a large number of parts constituting it, or the manufacturing method is complicated and the manufacturing cost is high.

また、薬液の点滴を受ける患者の病状などに応じ、一の溶解液に複数の薬剤を溶解混合する場合があり、そのためには、まず、最初の薬剤容器を両頭針付き溶解液容器に連結して、その薬剤容器に収容されている薬剤を溶解液に溶解させて混合し、その後、空になった使用済みの薬剤容器を取り外し、次いで、別の新たな薬剤容器を両頭針付き溶解液容器に連結し、薬剤を溶解液に溶解させて混合するという操作を繰り返す必要がある。
しかし、従来の両頭針付き溶解液容器は、両頭針を、溶解液容器の口部に刺通した状態で強固に固定することができないため、使用済みの薬剤容器を取り外す際に、両頭針が溶解液容器の口部から抜け出てしまい、溶解液が漏出する恐れがあった。また、新たな薬剤容器に両頭針を刺通する際に、両頭針が安定しておらず、正確な刺通操作が難しいという問題があった。
つまり、従来の両頭針付き溶解液容器では、複数の薬剤容器を交換しつつ、薬剤の溶解混合操作を繰り返し行うことが難しいという問題がある。
In addition, depending on the medical condition of the patient who is instilled with a drug solution, multiple drugs may be dissolved and mixed in one solution. To do so, first connect the first drug container to a solution container with a double-ended needle. The drug contained in the drug container is dissolved and mixed in the solution, and then the used drug container that has been emptied is removed, and then another new drug container is added to the solution container with a double-ended needle. It is necessary to repeat the operation of dissolving the drug in the solution and mixing.
However, the conventional double-ended lysate container cannot be firmly fixed with the double-ended needle pierced into the mouth of the lysate container. There was a risk that the solution would leak out from the mouth of the solution container and the solution would leak out. Further, when the double-ended needle is pierced into a new medicine container, there is a problem that the double-ended needle is not stable and accurate piercing operation is difficult.
In other words, the conventional solution container with a double-ended needle has a problem that it is difficult to repeatedly perform the drug dissolution and mixing operation while exchanging a plurality of drug containers.

また、特開平5−317383号公報(特許文献2)には、溶解液容器の口部上に両頭針ユニットが装着された両頭針付き溶解液容器が記載されている。
この両頭針付き溶解液容器は、溶解液容器と薬剤容器との連結時に、薬剤容器の首部を両頭針の上部に拘束するものであるため、薬剤の溶解混合操作の後、使用済みの薬剤容器を取り外す際に、両頭針が薬剤容器に引っ張られて、溶解液容器の口部のゴム製栓体から抜け出てしまう恐れがある。したがって、複数の薬剤容器を交換しつつ、薬剤の溶解混合操作を繰り返し行うことが難しいという問題がある。

A suspension belt 8 is provided for suspension on a belt or the like.

図5、図6および図7に示す両頭針3は、硬質のポリプロピレンによって、インジェクション成形されたものであり、材質としては、硬質のポリプロピレンの他、硬質のポリエチレンなどの合成樹脂やステンレスなどの金属を採用することができる。
両頭針3の下部側は、溶解液容器6と薬剤容器Aを連結する際に、栓体4を刺通する一方針部31とされ、上部側は、薬剤容器Aの開口シール部A2に嵌着されているゴム製栓体を刺通する他方針部32とされており、これら両針部とも、先端は鋭く尖った円錐状に形成されている。
また、両頭針3の内部には、一方針部31から他方針部32まで連通する2本の連通路33が設けられており、溶解液容器6と薬剤容器Aを連結した場合に、両容器の内部空間を連通できるようになっている。
The double-ended needle 3 shown in FIGS. 5, 6 and 7 is injection-molded with hard polypropylene, and the material is not only hard polypropylene but also synthetic resin such as hard polyethylene or metal such as stainless steel. Can be adopted.
The lower side of the double-ended needle 3 is a policy portion 31 that pierces the stopper 4 when the solution container 6 and the drug container A are connected, and the upper side is fitted to the opening seal portion A2 of the drug container A. It is set as the other policy part 32 which penetrates the rubber | gum plug body currently worn, and the tip of both these needle parts is formed in the shape of a sharp pointed cone.
The double-ended needle 3 is provided with two communication passages 33 communicating from one policy part 31 to the other policy part 32. When the solution container 6 and the drug container A are connected, both containers The internal space of can be communicated.

両頭針3には、その軸方向中央部より少し上部の側周面から、同心円状に張り出すように円盤部34が形成されている。この円盤部34の直径は、薬剤容器Aの口部シール部A2の直径よりも少し小さく、また、円盤部34の周縁部の上面には、8個の突起部35が突設されている。
円盤部34の下方において両頭針3の側部には、軸方向に延びる2本のガイド凸条部36が形成されている。このガイド凸条部36は、上記のとおり、蓋体2の両頭針保持孔241の内側面に形成された2本のガイド溝部242と係合して、両頭針3の回転を防ぐ。
A disc portion 34 is formed on the double-ended needle 3 so as to project concentrically from the side peripheral surface slightly above the central portion in the axial direction. The diameter of the disk part 34 is slightly smaller than the diameter of the mouth part seal part A2 of the medicine container A, and eight protrusions 35 project from the upper surface of the peripheral part of the disk part 34.
Two guide ridges 36 extending in the axial direction are formed on the side of the double-ended needle 3 below the disk portion 34. As described above, the guide protrusions 36 engage with the two guide grooves 242 formed on the inner surface of the double-ended needle holding hole 241 of the lid 2 to prevent the double-ended needle 3 from rotating.

また、ガイド凸条部36の下方において両頭針3の側部には、正面形状が逆三角形の2個の係止凸部37が形成されている。
この係止凸部37は、溶解液容器6と薬剤容器Aとの連結時において、両頭針3を下部位置に固定するための係止手段である。すなわち、前記両容器の連結時において、両頭針3の一方針部31が、栓体4を刺通して反対側(溶解液容器6の内側)に突出する際に、係止凸部37も一緒に突出し、すると係止凸部37は、その逆三角形の形状によってアンカー効果を生ずるため、栓体4から一方針部31を抜け難くすることができる。その結果、両頭針3の上方への移動を抑制し、下部位置に止めることができる。
In addition, two locking projections 37 whose front shape is an inverted triangle are formed on the side of the double-ended needle 3 below the guide projection 36.
The locking projection 37 is locking means for fixing the double-ended needle 3 to the lower position when the dissolution liquid container 6 and the drug container A are connected. That is, when the two containers are connected, when the one-pronged portion 31 of the double-ended needle 3 pierces the stopper body 4 and protrudes to the opposite side (inside the solution container 6), the locking convex portion 37 is also brought together. Then, the locking projection 37 has an anchor effect due to its inverted triangular shape, so that it is difficult to remove the one policy portion 31 from the plug body 4. As a result, the upward movement of the double-ended needle 3 can be suppressed and stopped at the lower position.

蓋体2の筒状部21の上端は、上記のとおり、薬剤容器Aの挿入口23として開口しているが、未使用時には、塵などの異物の侵入を防ぐために、シール部材5によって密閉されている。
シール部材5は、紙の層とポリプロピレンの層を有する2層構造のシートからなり、ポリプロピレン層をシール面として、挿入口23の口縁に加熱溶着されている。

蓋体2は、溶解液容器6の口部61と接続されている。詳しくは、蓋2の栓体保持部25の周縁部251の下面が、溶解液容器6の口部61の周縁に形成されたフランジ部62の上面と、超音波シール法により溶着され、口部61を密封するシール部63とされている。
上記のとおり、蓋体2の栓体保持部25内には、栓体4が配設されているため、溶解液容器6のフランジ部6に蓋体2の栓体保持部25を溶着し、溶解液容器6の口部61を密封する工程によって、同時に、口部61に栓体4を取り付けることができる。したがって、両頭針付き溶解液容器1の製造工程を簡略化できるため、製造コストを低減することができる。
The lid body 2 is connected to the mouth portion 61 of the solution container 6. Specifically, the lower surface of the peripheral edge portion 251 of the plug body holding portion 25 of the lid 2 is welded to the upper surface of the flange portion 62 formed on the peripheral edge of the mouth portion 61 of the solution container 6 by an ultrasonic sealing method. A seal portion 63 that seals 61 is used.
As described above, since the plug body 4 is disposed in the plug body holding section 25 of the lid body 2, the plug body holding section 25 of the lid body 2 is welded to the flange section 6 of the solution container 6, The plug body 4 can be attached to the mouth portion 61 at the same time by the step of sealing the mouth portion 61 of the solution container 6. Therefore, since the manufacturing process of the solution container 1 with a double-ended needle can be simplified, the manufacturing cost can be reduced.

溶解液容器6は、軟質のポリプロピレンを用いてブロー成形された中空の容器であり、本実施形態では、この中空部に溶解液Cとして、生理食塩水が収容されている。
図1に示すとおり、溶解液容器6の上端は、蓋体2と接続する口部61であり、下端には、両頭針付き溶解液容器1の使用時に、点滴チューブ(図示せず)などを接続する注出口蓋7が備えられており、さらに注出口蓋7の下部には、脚部71が連設されている。
溶解液容器本体6の材質としては、軟質のポリプロピレンの他、軟質のポリエチレン等のポリオレフィン系樹脂、環状ポリオレフィン、ポリ塩化ビニル、エチレン・酢酸ビニル共重合体、アイオノマー樹脂やこれらの2種以上の混合物などを採用することができるが、軟質のポリプロピレンは耐熱性が高く、加熱殺菌に対する適性に優れているため好ましい。
The solution container 6 is a hollow container blow-molded using soft polypropylene. In this embodiment, physiological saline is stored as the solution C in the hollow portion.
As shown in FIG. 1, the upper end of the dissolution liquid container 6 is a mouth portion 61 connected to the lid body 2, and an infusion tube (not shown) or the like is provided at the lower end when the dissolution liquid container 1 with a double-ended needle is used. A spout lid 7 to be connected is provided, and a leg portion 71 is connected to the lower portion of the spout lid 7.
The material of the solution container body 6 includes soft polypropylene, polyolefin resin such as soft polyethylene, cyclic polyolefin, polyvinyl chloride, ethylene / vinyl acetate copolymer, ionomer resin and a mixture of two or more thereof. However, soft polypropylene is preferable because of its high heat resistance and excellent suitability for heat sterilization.

また、溶解液容器6の容器璧は、複数の性質の異なる合成樹脂を積層した多層構造とし、機能性の向上を図ることができる。
例えば、溶解液容器6の容器璧の合成樹脂層が2層構造である場合は、溶解液と直接触れる内層を環状ポリオレフィンとし、外層をポリプロピレンとすることができる。また、合成樹脂層が3層構造である場合は、内層および外層をポリプロピレンとし、中間層をオレフィン系エラストマーとすることができ、或いは、内層および外層をポリエチレンとし、中間層をエチレン・酢酸ビニル共重合体とすることができる。
なお、本実施形態における溶解液容器6の容器壁は、上記のとおり、軟質のポリプロピレンによる単層構造である。
Moreover, the container wall of the solution container 6 has a multilayer structure in which a plurality of synthetic resins having different properties are laminated, so that the functionality can be improved.
For example, when the synthetic resin layer of the container of the solution container 6 has a two-layer structure, the inner layer that directly contacts the solution can be a cyclic polyolefin, and the outer layer can be a polypropylene. When the synthetic resin layer has a three-layer structure, the inner layer and the outer layer can be made of polypropylene and the intermediate layer can be made of an olefin-based elastomer, or the inner layer and the outer layer can be made of polyethylene, and the intermediate layer can be made of ethylene / vinyl acetate. It can be a polymer.
In addition, the container wall of the solution container 6 in the present embodiment has a single layer structure made of soft polypropylene as described above.

次に、本発明の両頭針付き溶解液容器1の使用方法を、図8〜図11に基づいて説明する。
まず、両頭針付き溶解液容器1の筒状部21の上端からシール部材5を剥離除去し、挿入口23を開口する。次に、別途用意した薬剤容器Aを、その開口シール部A2側から前記挿入口23に挿入し、下方向に押し込むと、開口シール部A2のゴム製栓体が、上部位置で保持されている両頭針3の他方針部32で刺通される。
さらに、薬剤容器Aを下方向に押し、図8に示すように、薬剤容器Aの口部シール部A2が、両頭針3の円盤部34上面に到達すると、両頭針3にかかる荷重が大きくなるので、両頭針3は、薬剤容器Aとともに蓋体2の両頭針保持孔241に沿って下部位置まで移動し、図9に示すように、両頭針3の一方針部31で栓体4が刺通される。
Next, the usage method of the solution container 1 with a double-ended needle of this invention is demonstrated based on FIGS.
First, the sealing member 5 is peeled and removed from the upper end of the cylindrical portion 21 of the double-ended needle-equipped lysing solution container 1, and the insertion port 23 is opened. Next, when a separately prepared medicine container A is inserted into the insertion port 23 from the opening seal portion A2 side and pushed downward, the rubber stopper of the opening seal portion A2 is held at the upper position. It is pierced by the other policy part 32 of the double-ended needle 3.
Further, when the drug container A is pushed downward and the mouth seal part A2 of the drug container A reaches the upper surface of the disk part 34 of the double-ended needle 3 as shown in FIG. 8, the load applied to the double-ended needle 3 increases. Therefore, the double-ended needle 3 moves to the lower position along with the double-ended needle holding hole 241 of the lid 2 together with the medicine container A, and the plug 4 is inserted into the policy portion 31 of the double-ended needle 3 as shown in FIG. Passed.

その際、両頭針3の円盤部34が、筒状部底部22に立設された4本の係合片27の間を、その保有弾性に抗して押し拡げながら下方に進み、溶解液容器6と薬剤容器Aとの連結が完了すると同時に、係合片27の上端の係合凸部28が、円盤部34の周縁部上面と係合し、これにより両頭針3が、下部位置において筒状部底面22に固定される。
また、同時に、両頭針3の下部側の側部に設けられた係止凸部37が、栓体4を突き抜けて反対側に突出した状態となり、そのアンカー効果によって、両頭針3が下部位置においてより強く固定される。
こうして、薬剤容器Aと溶解液容器6とが、両頭針3を介して連通されたら、次いで、両頭針付き溶解液容器1の上下を逆転させると、溶解液容器6内の溶解液Cが薬剤容器A内に流入し、薬剤容器A内の薬剤が溶解され混合して薬液となる。その後、薬剤容器Aを上にして、溶解液容器6内に薬剤容器A内の薬液を戻すことで、溶解液と薬剤との混合操作が完了する。
At that time, the disk portion 34 of the double-ended needle 3 advances downward between the four engagement pieces 27 erected on the cylindrical portion bottom portion 22 against its retained elasticity, and moves downward. At the same time as the connection between 6 and the medicine container A is completed, the engaging convex portion 28 at the upper end of the engaging piece 27 engages with the upper surface of the peripheral portion of the disc portion 34, whereby the double-ended needle 3 is in the cylinder position at the lower position. It is fixed to the bottom surface 22 of the shape portion.
At the same time, the locking projection 37 provided on the lower side portion of the double-ended needle 3 is in a state of protruding through the plug body 4 and protruding to the opposite side, and due to the anchor effect, the double-ended needle 3 is in the lower position. It is fixed more strongly.
Thus, when the medicine container A and the solution container 6 are communicated with each other via the double-ended needle 3, then the solution C in the solution container 6 is converted into the drug when the solution container 1 with double-ended needle is turned upside down. It flows into the container A, and the drug in the drug container A is dissolved and mixed to form a drug solution. Thereafter, the drug container A is turned up and the drug solution in the drug container A is returned to the solution container 6 to complete the mixing operation of the solution and the drug.

なお、溶解液Cに対し、複数の種類の薬剤を溶解混合する場合には、まず、使用済みの薬剤容器Aを、両頭針3の他方針部32から引き抜いて取り外し、次に、新たな薬剤容器Aを連結して、収容されている薬剤を溶解混合するという一連の操作を、必要回数だけ繰り返せばよい。
その際、両頭針3は、前記係合片27による拘束作用と前記係止凸部37による係止作用によって、下部位置にしっかりと固定されているので、両頭針3が、使用済み薬剤容器Aの取り外しの際に上方に引っ張られても、その一方針部31が栓体4から抜け出てしまうことがない。したがって、針抜けに起因する液漏れを起こし難く、両頭針3の安定性が保持され、薬剤容器Aの交換を、何度でも安全かつ確実に行うことができる。
以上の溶解液Cと薬剤との混合操作が完了した後は、溶解液容器6の下端の注出口蓋7に、点滴チューブ(図示せず)などを接続し、両頭針付き溶解液容器1の上部の懸吊ベルト8を、ハンガー(図示せず)などに掛けることによって、患者に対する薬液の点滴投与を行うことができる。
When a plurality of types of drugs are dissolved and mixed in the solution C, the used drug container A is first removed from the other policy portion 32 of the double-ended needle 3 and then removed. A series of operations of connecting the container A and dissolving and mixing the contained medicine may be repeated as many times as necessary.
At that time, the double-ended needle 3 is firmly fixed to the lower position by the restraining action by the engaging piece 27 and the latching action by the locking projection 37, so that the double-ended needle 3 is used in the used medicine container A. The one policy portion 31 does not come out of the plug body 4 even if it is pulled upward at the time of removal. Therefore, liquid leakage due to needle removal is unlikely to occur, the stability of the double-ended needle 3 is maintained, and the drug container A can be exchanged safely and reliably any number of times.
After the above mixing operation of the solution C and the drug is completed, an infusion tube (not shown) or the like is connected to the spout lid 7 at the lower end of the solution container 6 to By hanging the upper suspension belt 8 on a hanger (not shown) or the like, the patient can be instilled with a medical solution.

本発明は、構成部品が少ないため製造工程を簡略化して製造コストを低減でき、さらに、使用済みの薬剤容器を取り外す際などに、両頭針が溶解液容器の口部から抜け出てしまうことがないため、針抜けに起因する液漏れを起こし難く、薬剤容器の交換を安全かつ確実に行うことができる両頭針付き溶解液容器として有用である。   Since the present invention has few components, the manufacturing process can be simplified and the manufacturing cost can be reduced. Further, when removing a used medicine container, the double-ended needle does not come out of the mouth of the solution container. Therefore, it is difficult to cause liquid leakage due to needle removal, and it is useful as a solution container with a double-ended needle that can safely and reliably replace the drug container.
