しかし、前記容器兼用注射器においては、前記ハブルアーロックが注射針を取り付けるためにＩＳＯ規格に適合したテーパを有するルアー先と注射針を安全に固定するロックネジを備えている。ところで、容器兼用注射器が前記保護キャップを装着した形態で医療機関に提供される場合、医師が保護キャップを外してから自分で選んだサイズの注射針をルアー先に取り付けて使用するので、薬剤やその投与の仕方により、必ずしも前記ロックネジを必要としない場合がある。そのような場合は、むしろロックネジがあると注射針を、その針もとの外周フランジ部をロックネジにねじ込みながらルアー先に装着しなければならないと共に、ロックネジに針もとをねじ込んだ注射針は針の刃面がどの向きに止まるかが判らない不便さもあって、ルアー先だけを有するハブ部品（注射針取付部）を備えて無菌性を保証可能とした容器兼用注射器を要望されることが多い。   However, in the syringe for both containers, the hub luer lock includes a luer tip having a taper conforming to the ISO standard and a lock screw for safely fixing the injection needle in order to attach the injection needle. By the way, when a container-use syringe is provided to a medical institution with the protective cap attached, a syringe of the size selected by the doctor after removing the protective cap is attached to the luer tip and used. Depending on the administration method, the lock screw may not be necessary. In such a case, if there is a lock screw, the injection needle must be attached to the luer tip while the outer peripheral flange portion of the needle is screwed into the lock screw, and the injection needle screwed into the lock screw is the needle. In many cases, it is inconvenient that the direction of the blade surface will stop, and there is often a need for a container-use syringe that has a hub part (injection needle mounting portion) that has only a luer tip and can guarantee sterility. .

本発明は、上記事情に鑑みてなされたものであって、シリンダにおける前部のストッパーの先端からルアー先または注射針の先端までの滅菌を容易に、かつ確実に行えるようにすると共に、滅菌後における無菌性を確実に保証することができ、取り扱いが容易である容器兼用注射器を提供することを目的とする。   The present invention has been made in view of the above circumstances, and enables easy and reliable sterilization from the tip of the front stopper of the cylinder to the tip of the luer tip or the injection needle. An object of the present invention is to provide a container-use syringe that can reliably ensure sterility in the container and is easy to handle.

本発明によれば、以下の優れた効果を奏する。
請求項１に係る容器兼用注射器によれば、ルアー先ハブの外部カラーに、従来のハブルアーロックのように注射針をルアーロック部に固定するロックネジが設けられていないので、医者が使用するにあたり、注射針の針もとをルアー先に回転しながら挿入する必要がないと共に、注射針の刃面の位置を自由に選択することができて、簡単に注射針を容器兼用注射器へ装着することができる。
また、前記容器兼用注射器は各部品の組み付け、滅菌、包装等の多くの工程を経た後に包装されて最終製品として出荷される間は、キャップが係脱部によってルアー先ハブにしっかりと取り付けられていて不用意に外れることがないので、キャップのラビリンス筒部とルアー先との嵌合部にラビリンス機構がしっかりと構成され、該ラビリンス機構によって前記キャップの外部から内部に微生物が侵入するのを確実に阻止することができる。
したがって、前記容器兼用注射器は、滅菌後医療現場でキャップを取り外して使用されるまで、前部のストッパーの先端からルアー先全体までの滅菌後における無菌性を確実に保証することができると共に、操作や取り扱いが容易である。 The present invention has the following excellent effects.
According to the container and syringe according to claim 1, since the lock collar for fixing the injection needle to the luer lock portion is not provided on the outer collar of the luer tip hub like the conventional hub lure lock, it is necessary for the doctor to use it. It is not necessary to insert the needle base of the injection needle while rotating it toward the luer tip, and the position of the blade surface of the injection needle can be freely selected, and the injection needle can be easily attached to the container-use syringe. Can do.
In addition, while the container-combined syringe is packaged after many steps such as assembly of components, sterilization, and packaging, and shipped as a final product, the cap is firmly attached to the luer tip hub by the engagement / disengagement part. Therefore, the labyrinth mechanism is firmly constructed at the fitting part between the labyrinth tube part of the cap and the luer tip, and the labyrinth mechanism ensures that microorganisms enter the inside from the outside of the cap. Can be prevented.
Therefore, the container-use syringe can reliably guarantee sterility after sterilization from the front end of the front stopper to the entire luer tip until the cap is removed and used at the medical site after sterilization. And easy to handle.

請求項２に係る容器兼用注射器によれば、請求項１に記載の容器兼用注射器と同様な効果を奏する他に、ルアー先ハブのバイパスチャンバー部の先端に前記ルアー先を囲む突出部が設けられていないので、キャップをルアー先ハブから外したとき、ルアー先の全体が露出するため、注射針をルアー先に容易に取り付けることができる。   According to the container and syringe according to claim 2, in addition to the same effect as the container and syringe according to claim 1, a protrusion surrounding the luer tip is provided at the tip of the bypass chamber portion of the luer tip hub. Since the entire luer tip is exposed when the cap is removed from the luer tip hub, the injection needle can be easily attached to the luer tip.

請求項３に係る容器兼用注射器によれば、前部のストッパーの先端からルアー先に装着された注射針の全体までの滅菌後における無菌性を、プロテクターをルアー先ハブから外して使用するまでの間確実に保証することができると共に、請求項１に記載の容器兼用注射器と同様に外部カラーに注射針用のロックネジが設けられていないので、使用時に必要に応じて注射針の刃面位置を自由に調節することができ、操作や取り扱いが容易である。   According to the container combined syringe according to claim 3, the sterility after the sterilization from the tip of the front stopper to the whole injection needle attached to the luer tip is used until the protector is removed from the luer tip hub and used. Since the outer collar is not provided with a lock screw for the injection needle as in the case of the container-use syringe according to claim 1, the blade surface position of the injection needle can be adjusted as required during use. It can be freely adjusted and is easy to operate and handle.

請求項４に係る容器兼用注射器によれば、前部のストッパーの先端からルアー先または筒先に固定された注射針の全体までの滅菌後における無菌性を、プロテクターをルアー先ハブから外して使用するまでの間確実に保証することができると共に、請求項２に記載の容器兼用注射器と同様にルアー先や筒先を囲む突出物が存在しないので、注射をし易い利点がある。   According to the syringe for both containers according to claim 4, the sterility after sterilization from the tip of the front stopper to the whole of the injection needle fixed to the luer tip or the tube tip is used by removing the protector from the luer tip hub. In the same manner as in the container and syringe according to claim 2, there is no protrusion surrounding the luer tip or the tube tip, and therefore there is an advantage that injection is easy.

前記構成の容器兼用注射器１においては、例えば、フィンガーグリップ４を嵌着し内部に前部ストッパー５ａを挿入したシリンダ２にルアー先ハブ３を嵌着部１０を介して嵌着し、前記キャップ７のラビリンス筒部１４をルアー先ハブ３のルアー先９に嵌合させると共に、前記フランジ部１５のリング状部１６をルアー先ハブ３の外部カラー１１に嵌合させて、該外部カラー１１の環状溝１２に突起１７を係合させることにより、キャップ７をルアー先ハブ３に装着する。この状態で容器兼用注射器１を滅菌室内に搬送して、蒸気や滅菌ガスに接触させると、蒸気や滅菌ガスは、前記微小隙間２０から外部カラー１１とキャップ７のラビリンス筒１４の外側との間の空間Ｇに侵入した後、ラビリンス機構１９を経由してキャップ７内に入り、ルアー先９の内孔９ａを通ってバイパスチャンバー８ａに入り、シリンダー２の先端に挿入された前部ストッパー５ａの前面に至り、この間にこの経路の周面全てが蒸気や滅菌ガスに接触することによって滅菌される。   In the container / syringe 1 having the above-described configuration, for example, the luer tip hub 3 is fitted through the fitting portion 10 to the cylinder 2 into which the finger grip 4 is fitted and the front stopper 5a is inserted, and the cap 7 The labyrinth tube portion 14 is fitted to the luer tip 9 of the luer tip hub 3, and the ring-like portion 16 of the flange portion 15 is fitted to the outer collar 11 of the luer tip hub 3. The cap 7 is attached to the luer tip hub 3 by engaging the protrusion 17 with the groove 12. In this state, when the container / syringe 1 is transported into the sterilization chamber and brought into contact with the vapor or sterilization gas, the vapor or sterilization gas flows between the external gap 11 and the outside of the labyrinth cylinder 14 of the cap 7 from the minute gap 20. Of the front stopper 5a inserted into the tip of the cylinder 2 through the labyrinth mechanism 19 and into the cap 7, through the inner hole 9a of the luer tip 9, and into the bypass chamber 8a. At the same time, the entire circumference of this path is sterilized by contact with steam or sterilization gas.

そして、前記のようにして滅菌された容器兼用注射器は、シリンダ２内に薬剤が充填されて、後部のストッパー５ｂにより封止された後に、適宜の包装体に収納されて医療現場等に供給される。医療現場では、医者は、所要時に包装体から容器兼用注射器１を取り出した後に、前記キャップ７を掴んでルアー先ハブ３から強めに引き抜くことにより、前記ルアー先ハブ３とキャップ７との係脱部２１の係合状態（外部カラー１１の環状溝１２とキャップ７のリング状部１５の突起１６または環状突起との係合）を解除して、前記ルアー先９からキャップ７を取り外す。しかる後に、滅菌済みの注射針を、その針もとを前記ルアー先９に挿入して容器兼用注射器１に装着して、患者等に薬剤を投与する。   The container-use syringe sterilized as described above is filled with a medicine in the cylinder 2 and sealed with the stopper 5b at the rear, and then stored in an appropriate package and supplied to a medical site or the like. The At the medical site, the doctor removes the container-use syringe 1 from the package when necessary, and then grasps the cap 7 and pulls it strongly out of the luer tip hub 3 to disengage the luer tip hub 3 from the cap 7. The engagement state of the portion 21 (engagement between the annular groove 12 of the outer collar 11 and the protrusion 16 or the annular protrusion of the ring-shaped portion 15 of the cap 7) is released, and the cap 7 is removed from the luer tip 9. Thereafter, a sterilized injection needle is inserted into the luer tip 9 with the needle base inserted into the container-use syringe 1 to administer the drug to a patient or the like.

前記実施の形態に係る容器兼用注射器１によれば、医者が注射針を容器兼用注射器１に装着する場合、前記ルアー先ハブ３の外部カラー１１には、従来のハブルアーロックのように注射針をルアーロック部に固定するロックネジが設けられていないので、注射針の針もとをルアー先９に回転しながら挿入する必要がないと共に、前記ロックネジと針もととの最終螺合位置によって注射針の刃面の向きが変化することもなく、医者は、注射針の刃面の位置を自由に選択し、例えば、容器兼用注射器１のフィンガーグリップ等の向きに合わせ、簡単に注射針を容器兼用注射器１へ装着することができる。   According to the container / use syringe 1 according to the embodiment, when a doctor attaches an injection needle to the container / use syringe 1, the outer collar 11 of the luer tip hub 3 is provided with an injection needle like a conventional hub lure lock. Since there is no lock screw for fixing the luer lock part to the luer lock part, it is not necessary to insert the needle base of the injection needle into the luer tip 9 while rotating, and injection is performed depending on the final screwing position between the lock screw and the needle base. Without changing the direction of the needle blade surface, the doctor can freely select the position of the blade surface of the injection needle, for example, match the direction of the finger grip of the syringe 1 for both containers, and easily place the injection needle into the container. It can be attached to the combination syringe 1.

また、前記容器兼用注射器１は前記のように各部品の組み付け、滅菌、包装等の多くの工程を経た後に包装されて最終製品として出荷されるが、その間に、前記キャップ７は、前記係脱部２１によってルアー先ハブ３にしっかりと取り付けられていて、不用意に外れることないので、キャップ７のラビリンス筒部１４とルアー先９との嵌合部にラビリンス機構１９がしっかりと構成されており、前記キャップ７の外部からその内部に侵入しようとする微生物は前記ラビリンス機構１９によって侵入を阻止される。したがって、前記容器兼用注射器１は、滅菌後医療現場でキャップ７を取り外して使用されるまで、前部のストッパー５ａの先端からルアー先９の全体までの滅菌後における無菌性を保証することができる。   Further, the container-use syringe 1 is packaged and shipped as a final product after undergoing many steps such as assembly of components, sterilization, and packaging as described above. The labyrinth mechanism 19 is firmly constructed in the fitting portion between the labyrinth tube portion 14 of the cap 7 and the luer tip 9 because it is firmly attached to the luer tip hub 3 by the portion 21 and does not come off carelessly. Microorganisms trying to enter the cap 7 from the outside are blocked by the labyrinth mechanism 19. Accordingly, the container / syringe 1 can guarantee sterility after sterilization from the tip of the front stopper 5a to the entire luer tip 9 until the cap 7 is removed and used at the medical site after sterilization. .

この実施の形態に係る容器兼用注射器１Ｂによれば、前記プロテクター７Ｂを、前記係脱部２１によってルアー先ハブ３の外部カラー１１に確実に保持させることができると共に、前記ラビリンス機構１９によって微生物のプロテクター７Ｂ内への侵入が阻止されるため、前部ストッパー５ａの先端からルアー先９に装着されている注射針２５の全体までの滅菌後における無菌性を、前記プロテクター７Ｂを前記ルアー先ハブ３から外して使用するまでの間確実に保証することができる。
また、前記ルアー先ハブ３の外部カラー１１には、前記のように注射針２５を固定するロックネジが設けられていないので、注射時に医者が注射針２５の針もと２５ａをルアー先９の回りに回転させて注射針２５の刃面２５ｅの向きを必要に応じて自由に調節することができる。 According to the container combined syringe 1B according to this embodiment, the protector 7B can be reliably held on the external collar 11 of the luer tip hub 3 by the engagement / disengagement part 21, and the labyrinth mechanism 19 Since the intrusion into the protector 7B is prevented, the sterility after sterilization from the front end of the front stopper 5a to the entire injection needle 25 attached to the luer tip 9 is determined by using the protector 7B and the luer tip hub 3 It can be reliably guaranteed until it is used after being removed.
Further, since the outer collar 11 of the luer tip hub 3 is not provided with the lock screw for fixing the injection needle 25 as described above, the doctor places the needle 25a of the injection needle 25 around the luer tip 9 at the time of injection. The direction of the blade surface 25e of the injection needle 25 can be freely adjusted as necessary.

次に、図６は本発明の第４の実施の形態に係る容器兼用注射器１Ｃを示す。
この容器兼用注射器１Ｃは、第２の実施の形態に係る容器兼用注射器１Ａにおける外周をテーパ面とした注射針取付部としてのルアー先９（図６（ａ）参照）または外周を平行面とした筒先（注射針取付部）９’（図６（ｂ）参照）に直接に注射針の針管２６が固定された構成に相当するものであり、キャップ７Ａと基本的に同様な構成とされた注射針保護用のプロテクター７Ｃが、キャップ７Ａに代わって、前記変形のルアー先ハブ３の筒先基部２２に係脱部２１を介して着脱可能に装着されている。この実施の形態に係る容器兼用注射器１Ｃにおいても、前記係脱部２１における構成として、図６に示すように、前記筒先基部２２の雄ねじ２２ｂにリング状部１５の雌ねじ２４ａを螺合させる形式（図４（ｂ）に図示の形式に相当）や、筒先基部２２の環状溝２２ａにリング状部１６の突起２４を係合させる形式（図４（ａ）に図示の形式に相当）を採用することができる。 Next, FIG. 6 shows a container / use syringe 1C according to a fourth embodiment of the present invention.
This syringe 1C for both containers is a luer tip 9 (see FIG. 6 (a)) as an injection needle mounting portion having a tapered outer periphery in the container combined syringe 1A according to the second embodiment, or a parallel outer surface. The injection corresponds to a configuration in which the needle tube 26 of the injection needle is directly fixed to the tube tip (injection needle mounting portion) 9 ′ (see FIG. 6B), and the injection basically has the same configuration as the cap 7A. A protector 7C for protecting the needle is detachably attached to the tube base 22 of the modified luer hub 3 via the engagement / disengagement portion 21 instead of the cap 7A. Also in the container combined syringe 1C according to this embodiment, as a configuration in the engagement / disengagement part 21, as shown in FIG. 6, a form in which the female thread 24a of the ring-shaped part 15 is screwed into the male thread 22b of the cylindrical tip base part 22 ( 4 (b)) or a form in which the protrusion 24 of the ring-shaped portion 16 is engaged with the annular groove 22a of the tube base 22 (corresponding to the form shown in FIG. 4 (a)). be able to.

この実施の形態に係る容器兼用注射器１Ｃにおいては、滅菌する場合には、容器兼用注射器１Ａの場合と同様に、ルアー先ハブ３にプロテクター７Ｃを係脱部２１を介して装着した状態で行うと、蒸気や滅菌ガスはプロテクター７Ｃの外側から微小間隙２０を通り、前記リング状部１５と筒先基部２２との嵌合隙間を経て、前記ラビリンス機構１９の螺旋状の微小通路を通ってプロテクター７Ｃ内に入り、注射針の針管２６内を通ってバイパスチャンバー８ａ内に入り、シリンダ２の先端に挿入されている前部ストッパー５ａの前面に達し、この間の各内外面の全てが滅菌される。   In the container / syringe 1C according to this embodiment, when sterilizing, the protector 7C is mounted on the luer tip hub 3 via the engagement / disengagement part 21 as in the case of the container / syringe 1A. Steam or sterilizing gas passes through the minute gap 20 from the outside of the protector 7C, passes through the fitting gap between the ring-shaped portion 15 and the tube tip base portion 22, passes through the spiral minute passage of the labyrinth mechanism 19, and enters the protector 7C. Enters the bypass chamber 8a through the needle tube 26 of the injection needle and reaches the front surface of the front stopper 5a inserted at the tip of the cylinder 2, and all the inner and outer surfaces in between are sterilized.

この実施の形態に係る容器兼用注射器１Ｃによれば、前記プロテクター７Ｃが前記容器兼用注射器１のキャップ７Ａと同様に、前記係脱部２１によってルアー先ハブ３の筒先基部２２にしっかりと取り付けられていて、前記ラビリンス機構１９によって微生物のプロテクター７Ｃ内への侵入が阻止されるので、前部ストッパーの先端からルアー先９または筒先９’に固定された注射針の針管２６の全体までの滅菌後における無菌性を、前記プロテクター７Ｃを前記ルアー先ハブ３から外して使用するまでの間確実に保証することができる。また、ルアー先９や筒先９’を囲む前記容器兼用注射器１，１Ｂにおける外部カラー１１のような突出物が存在しないので、注射をし易い利点がある。   According to the container / use syringe 1C according to this embodiment, the protector 7C is firmly attached to the tube tip base portion 22 of the luer tip hub 3 by the engagement / disengagement portion 21 like the cap 7A of the container / use syringe 1. Since the labyrinth mechanism 19 prevents microorganisms from entering the protector 7C, the sterilization from the tip of the front stopper to the entire needle tube 26 of the injection needle fixed to the luer tip 9 or the tube tip 9 'is performed. Sterility can be reliably ensured until the protector 7C is removed from the luer tip hub 3 and used. Further, since there is no protrusion such as the outer collar 11 in the syringes 1 and 1B surrounding the luer tip 9 and the tube tip 9 ', there is an advantage that injection is easy.

なお、前記実施の形態に係る容器兼用注射器１，１Ａ，１Ｂ，１Ｃにおいては、前記シリンダ２内に前部ストッパー５ａを挿入した状態でシリンダ２にルアー先ハブ３を装着して、該ルアー先ハブ３にキャップ７，７Ａまたはプロテクター７Ｂ，７Ｃを装着して滅菌をする場合について説明したが、これに限らず、本発明に係る容器兼用注射器は、前部ストッパー５ａを挿入しないまま、前記のようにルアー先ハブ３とキャップ７，７Ａまたはプロテクター７Ｂ，７Ｃを装着して滅菌することもできる。この場合には、蒸気や滅菌ガスは、前記の場合とは異なり、シリンダ２の内側に直接入ることによって、また、キャップ７の外側から前記微小間隙２０、前記ラビリンス機構１９等を経ることによって注射器内部に入って、それらの接触面の全体を滅菌する。   In the syringes 1 and 1A, 1B, and 1C according to the embodiment, the luer tip hub 3 is attached to the cylinder 2 with the front stopper 5a inserted in the cylinder 2, and the luer tip Although the case where the cap 7 or 7A or the protector 7B or 7C is attached to the hub 3 for sterilization has been described, the present invention is not limited to this, and the container-use syringe according to the present invention does not include the front stopper 5a. In this manner, the luer tip hub 3 and the caps 7 and 7A or the protectors 7B and 7C can be mounted and sterilized. In this case, unlike the above case, the vapor or sterilizing gas enters the cylinder 2 directly, and also passes through the micro gap 20 and the labyrinth mechanism 19 from the outside of the cap 7. Once inside, sterilize all of their contact surfaces.
