Description

本発明は、注射器に吸引された不要な薬液及び気体を収容する注射器用容器に関する。 The present invention relates to a syringe container that contains unnecessary chemicals and gases sucked into a syringe.

注射器にバイアルから薬液を抜き取る場合、先ず、注射器内にバイアルから抜き取る薬液の体積と同じ体積の空気を吸い込み、次にバイアルの弾性キャップに注射針を穿刺する。次に、注射器のプランジャを往復動させて、注射器内の空気とバイアル内の薬液を置換させる。このとき、空気が注射器内に入り込む。 When extracting a drug solution from a vial into a syringe, first suck in the same volume of air as the volume of the drug solution to be withdrawn from the vial into the syringe, and then puncture the elastic cap of the vial with an injection needle. The syringe plunger is then reciprocated to replace the air in the syringe with the drug solution in the vial. At this time, air enters the syringe.

この空気を抜き取り、所望の量の薬液とするためには、注射針を上方に向け、空気を注射器内の空間の上方に配置させてプランジャを下死点に向って押し込むことで、注射器内から空気及び余分な薬液を抜く作業を行う。 In order to extract this air and obtain the desired amount of drug solution, the injection needle is pointed upward, the air is placed above the space inside the syringe, and the plunger is pushed toward the bottom dead point from the inside of the syringe. Work to remove air and excess chemicals.

このような、注射器内から空気及び余分な薬液を抜く作業を行う場合、注射器内から空気、及び、少量の薬液又は薬液を含むガスが吐出され、作業者に付着する虞や周囲に飛散する虞があり、周囲の汚染の原因となる。また、薬液が毒性を有するものである場合には、作業者の健康被害を引き起こす虞がある。 When performing such work of removing air and excess chemicals from the syringe, air and a small amount of chemicals or gas containing the chemicals are discharged from the syringe, and there is a risk of adhering to the operator or scattering to the surroundings. It causes pollution of the surroundings. In addition, if the chemical solution is toxic, it may cause health hazards to workers.

そこで、空気を抜く作業において、周囲の汚染を防止して注射器内の空気を抜くことが可能な空気抜き装置が知られている（例えば、特許文献１参照）。この空気抜き装置は、容器内に薬液を貯留する空間部と、当該空間部の空気を通気可能なフィルタ部と、を備え、フィルタ部で空気中に含まれる薬液を捕捉可能に形成されている。また、空気抜き装置は、空間部及びフィルタ部の間を連結する連通管を、空間部の内面から突起させることで、容器が傾斜等しても、薬液が外部に移動することを防止可能に形成されており、注射器内の空気を抜く作業を行っていても、薬液による周囲の汚染を防止することが可能に構成される。 Therefore, there is known an air bleeding device capable of preventing contamination of the surroundings and bleeding air in a syringe in the work of bleeding air (see, for example, Patent Document 1). This air bleeding device includes a space portion for storing the chemical solution in the container and a filter portion capable of ventilating the air in the space portion, and is formed so that the chemical solution contained in the air can be captured by the filter portion. Further, the air bleeding device is formed so that the communication pipe connecting the space portion and the filter portion is projected from the inner surface of the space portion so that the chemical solution can be prevented from moving to the outside even if the container is tilted or the like. Even if the air inside the syringe is evacuated, it is possible to prevent the surroundings from being contaminated by the chemical solution.

When air is sucked into the syringe 100 or when excess chemical solution is sucked in the suction of the chemical solution, unnecessary fluid is discharged into the syringe container 1. Specifically, as shown in FIG. 4, the needle portion 122 of the injection needle 112 is inserted from the opening of the needle tip guide portion 31 along the axial direction of the insertion portion 11. The needle portion 122 is inserted into the insertion portion 11 until the connecting portion 121 of the injection needle 112 abuts on the inner peripheral surface of the needle tip guide portion 31 and movement is restricted. At this time, the needle portion 122 passes through the needle tip guide portion 31 and the engaging portion 32, punctures the rubber stopper 23, and then moves to the front of the tip of the protection portion 43.

次に、プランジャを下死点に向かって押し込み、注射器１００内から不要な流体を針部１２２の先端から排出する。このとき、注射器１００から排出された不要な流体は、貯留部１２内に移動する。 Next, the plunger is pushed toward the bottom dead center, and unnecessary fluid is discharged from the tip of the needle portion 122 from the inside of the syringe 100. At this time, the unnecessary fluid discharged from the syringe 100 moves into the storage unit 12.

次に、使用者は、注射針１１２を挿入部１１から抜く。このとき、ゴム栓２３は、自身の復元力によって、針部１２２の穿刺により生じた穿孔が復元し、穿孔が閉塞される。結果、貯留部１２は、ゴム栓２３により外部と遮断され、排出した流体を貯留部１２内に貯留することが可能となる。このようにして、注射器１００内の不要な流体を排出し、注射器１００の使用が可能となる。不要な流体を貯留した注射器用容器１は、その後廃棄される。 Next, the user pulls out the injection needle 112 from the insertion portion 11. At this time, the rubber stopper 23 restores the perforation generated by the puncture of the needle portion 122 by its own restoring force, and the perforation is closed. As a result, the storage unit 12 is blocked from the outside by the rubber stopper 23, and the discharged fluid can be stored in the storage unit 12. In this way, unnecessary fluid in the syringe 100 is discharged, and the syringe 100 can be used. The syringe container 1 containing the unnecessary fluid is then discarded.

このように構成された注射器用容器１によれば、ゴム栓２３により貯留部１２を密封することで、注射器１００から排出した流体を漏洩させることなく、安全、且つ、確実に、注射器１００内の薬液及び薬液とともに吸い込まれた空気を排出することができる。このため注射器用容器１は、薬液の漏洩等による、作業者への影響や、周囲の汚染を防止することが可能となる。 According to the syringe container 1 configured in this way, by sealing the reservoir 12 with the rubber stopper 23, the fluid discharged from the syringe 100 is not leaked, and the inside of the syringe 100 is safely and surely. The chemical solution and the air sucked together with the chemical solution can be discharged. Therefore, the syringe container 1 can prevent the influence on the operator and the contamination of the surroundings due to the leakage of the chemical solution and the like.

注射器用容器１は、ゴム栓２３により挿入部１１の針部１２２が移動する通路の中途部を密封することで、外部空間と貯留部１２につながる保護部４３とを遮断することが可能となる。また、ゴム栓２３は、自身の復元力により針部１２２の穿刺により生じた穿孔を閉塞することから、当該穿孔を別途閉塞する必要がない。このため、注射器用容器１は、貯留部１２を閉塞する作業を要さず、作業性がよい。 The syringe container 1 can block the external space and the protective portion 43 connected to the storage portion 12 by sealing the middle portion of the passage through which the needle portion 122 of the insertion portion 11 moves with the rubber stopper 23. .. Further, since the rubber stopper 23 closes the perforation generated by the puncture of the needle portion 122 by its own restoring force, it is not necessary to separately close the perforation. Therefore, the syringe container 1 does not require the work of closing the storage unit 12, and has good workability.

また、注射器用容器１の挿入部１１は、ガイド部２１、胴部２２及びゴム栓２３の３つの部材により構成されることから、簡単な構成であって、且つ、部品点数が少ない。このため、注射器用容器１は安価、且つ、容易に製造することができる。 Further, since the insertion portion 11 of the syringe container 1 is composed of three members, a guide portion 21, a body portion 22, and a rubber stopper 23, the insertion portion 11 has a simple structure and a small number of parts. Therefore, the syringe container 1 can be manufactured inexpensively and easily.

また、挿入部１１は、貯留部１２内に位置する保護部４３を有することで、注射器１００の針部１２２が貯留部１２に位置するときには、その周囲に保護部４３が存在する。このため、針部１２２が直接貯留部１２に触れることが無く、パウチである貯留部１２が針部１２２により損傷し、穴が空くこと、及び、当該穴から薬液などが漏れることを防止できる。このため、注射器用容器１は、高い安全性を有する。 Further, since the insertion portion 11 has a protection portion 43 located in the storage portion 12, when the needle portion 122 of the syringe 100 is located in the storage portion 12, the protection portion 43 exists around the protection portion 43. Therefore, the needle portion 122 does not directly touch the storage portion 12, and the storage portion 12 which is a pouch can be prevented from being damaged by the needle portion 122, forming a hole, and leaking a chemical solution or the like from the hole. Therefore, the syringe container 1 has high safety.

また、挿入部１１は、針部１２２を挿入する部位に針先案内部３１を設けることで、針部１２２を広い開口面積の開口に入れることが可能となる。また、針先案内部３１は縮径することから、所定の位置に針部１２２を案内することができる。さらに、針先案内部３１は、開口する端部に鍔部３１ａを有することで、針部１２２を挿入するときに開口からずれた場合に、針部１２２が挿入部１１を持つ手指を刺すこと防止できる。 Further, the insertion portion 11 can insert the needle portion 122 into an opening having a wide opening area by providing the needle tip guide portion 31 at a portion where the needle portion 122 is inserted. Further, since the needle tip guide portion 31 has a reduced diameter, the needle portion 122 can be guided to a predetermined position. Further, the needle tip guide portion 31 has a collar portion 31a at the end portion to be opened, so that when the needle portion 122 is inserted, the needle portion 122 pierces the finger holding the insertion portion 11. Can be prevented.

また、貯留部１２は、挿入部１１に取り付けられたときに、脱気状態にあり、このため、注射器１００から排出された微量な流体により変化は微小なものとなる。これにより、流体が貯留された貯留部１２に外力が印加されても、ゴム栓２３の穿孔から流体が逆流すること、及び、ゴム栓２３が脱落することがない。 Further, the storage unit 12 is in a degassed state when it is attached to the insertion unit 11, and therefore, the change is minute due to the minute amount of fluid discharged from the syringe 100. As a result, even if an external force is applied to the storage portion 12 in which the fluid is stored, the fluid does not flow back from the perforation of the rubber stopper 23 and the rubber stopper 23 does not fall off.

また、ゴム栓２３は、第２部位２３ｂを取付部４２に嵌合させるとともに、第２部位２３ｂの軸方向の長さが取付部４２の開口の軸方向の長さ以下に構成される。このため、第２部位２３ｂが取付部４２に押圧されて弾性変形することで、ゴム栓２３が取付部４２に固定されるため、注射器用容器１は、ゴム栓２３が取付部４２から脱落することを防止できる。 Further, the rubber stopper 23 is configured such that the second portion 23b is fitted to the mounting portion 42 and the axial length of the second portion 23b is equal to or less than the axial length of the opening of the mounting portion 42. Therefore, the rubber stopper 23 is fixed to the attachment portion 42 by being pressed against the attachment portion 42 and elastically deforming the second portion 23b, so that the rubber stopper 23 falls off from the attachment portion 42 in the syringe container 1. Can be prevented.

上述したように本発明の第１の実施形態に係る注射器用容器１によれば、注射器１００から排出される流体を貯留部１２に安全に収容可能であり、また安価に製造できるとともに、高い生産性を有する。

Further, the needle tip guide portion 31A is configured such that the inner diameter on the engaging portion 32 side is smaller than the outer diameter of the tip of the connecting portion 121 and larger than the outer diameter of the needle portion 122. Further, the needle tip guide portion 31A has a disc-shaped flange portion 31a integrally provided on the outer peripheral surface of the end portion, and a guide wall 31b provided on the opening edge of the needle tip guide portion 31A.

ガイド壁３１ｂは、半円筒状に構成される。ガイド壁３１ｂは、針先案内部３１Ａの開口縁の半周に渡って設けられる。ガイド壁３１ｂの内周面の曲率半径は、連結部１２１の外周面の半径よりも大径に構成される。 The guide wall 31b is formed in a semi-cylindrical shape. The guide wall 31b is provided over half the circumference of the opening edge of the needle tip guide portion 31A.

(Third Embodiment)
Next, the configuration of the syringe container 1B according to the third embodiment of the present invention will be described with reference to FIGS. 7 and 8.
FIG. 7 is a front view showing the configuration of the syringe container 1B according to the third embodiment of the present invention, and FIG. 8 is a cross-sectional view showing the configuration of the insertion portion 11B used for the syringe container 1B. Of the configurations of the syringe container 1B according to the third embodiment, the configurations equivalent to the configurations of the syringe container 1 according to the first embodiment described above are designated by the same reference numerals and detailed. The description is omitted.

図７に示すように、注射器用容器１Ｂは、挿入部１１Ｂと、貯留部１２と、を備えている。 As shown in FIG. 7, the syringe container 1B includes an insertion portion 11B and a storage portion 12.

挿入部１１Ｂは、胴部２２Ｂと、ゴム栓２３と、を備えている。即ち、挿入部１１Ｂは、上述した注射器用容器１のガイド部２１を有さない構成である。 The insertion portion 11B includes a body portion 22B and a rubber stopper 23. That is, the insertion portion 11B does not have the guide portion 21 of the syringe container 1 described above.

胴部２２Ｂは、一端側に設けられた基部４１Ｂと、被係合部４１に一体に設けられる取付部４２と、取付部４２に一体に設けられた保護部４３Ｂと、を備えている。胴部２２Ｂは、樹脂材料、例えば、ポリプロピレンにより構成される。 The body portion 22B includes a base portion 41B provided on one end side, a mounting portion 42 integrally provided on the engaged portion 41, and a protective portion 43B integrally provided on the mounting portion 42. The body portion 22B is made of a resin material, for example, polypropylene.

基部４１Ｂは、円筒状に構成される。基部４１Ｂの内径は、ゴム栓２３の第１部位２３ａの外径と略同一径又は若干大径に構成される。基部４１Ｂは、軸方向で開口する端部から取付部４２までの長さが、第１部位２３ａよりも若干長く構成される。基部４１Ｂは、その外周面に一体に設けられた菱形板状や楕円板状の突起部４１ａと、その開口端の内周面に、複数の突起部４１ｃと、を有する。 The base 41B is formed in a cylindrical shape. The inner diameter of the base portion 41B is configured to be substantially the same as or slightly larger than the outer diameter of the first portion 23a of the rubber stopper 23. The base portion 41B is configured such that the length from the end portion that opens in the axial direction to the mounting portion 42 is slightly longer than that of the first portion 23a. The base portion 41B has a rhombic plate-shaped or elliptical plate-shaped protrusion 41a integrally provided on the outer peripheral surface thereof, and a plurality of protrusions 41c on the inner peripheral surface of the open end thereof.

突起部４１ｃは、基部４１Ｂの内周面からの高さが、基部４１Ｂの内周面からゴム栓２３の第１部位２３ａまでの距離よりも高く構成される。複数の突起部４１ｃは、ゴム栓２３が脱落する方向への移動を規制する規制部である。 The height of the protrusion 41c from the inner peripheral surface of the base 41B is higher than the distance from the inner peripheral surface of the base 41B to the first portion 23a of the rubber stopper 23. The plurality of protrusions 41c are regulation parts that regulate the movement of the rubber stopper 23 in the direction of falling off.

保護部４３Ｂは、取付部４２に一体に設けられ、先端が閉塞する円筒状に構成されるとともに、その先端側の外周面に単数又は複数の孔部４３ａを有する。保護部４３Ｂの内径は、取付部４２の内径よりも小径で、且つ、針部１２２の外径よりも大径に構成される。 The protective portion 43B is integrally provided with the mounting portion 42, has a cylindrical shape in which the tip is closed, and has one or a plurality of holes 43a on the outer peripheral surface on the tip side thereof. The inner diameter of the protective portion 43B is smaller than the inner diameter of the mounting portion 42 and larger than the outer diameter of the needle portion 122.

このように構成された挿入部１１Ｂを備える注射器用容器１Ｂによれば、上述した挿入部１１を備える注射器用容器１と同様の効果を奏する。加えて、挿入部１１Ｂは、胴部２２Ｂ及びゴム栓２３の２つの部品により構成されることから、製造コストを低減させることが可能となる。 According to the syringe container 1B having the insertion portion 11B configured as described above, the same effect as that of the syringe container 1 having the insertion portion 11 described above is obtained. In addition, since the insertion portion 11B is composed of two parts, the body portion 22B and the rubber stopper 23, the manufacturing cost can be reduced.

また、挿入部１１Ｂは、胴部２２Ｂの基部４１Ｂの端部を開口させて、この開口から注射器１００の針部１２２を挿入し、ゴム栓２３を穿刺する構成である。このため、開口面積を確保することができるため、穿刺作業の作業性が低下することを防止できる。また、胴部２２Ｂの保護部４３Ｂの先端を閉塞し、孔部４３ａから貯留部１２に流体を排出する構成とすることで、針部１２２が保護部４３Ｂを越えて貯留部１２に接触することを防止できる。 Further, the insertion portion 11B has a configuration in which the end portion of the base portion 41B of the body portion 22B is opened, the needle portion 122 of the syringe 100 is inserted through this opening, and the rubber stopper 23 is punctured. Therefore, since the opening area can be secured, it is possible to prevent the workability of the puncture work from being lowered. Further, the tip of the protective portion 43B of the body portion 22B is closed, and the fluid is discharged from the hole portion 43a to the storage portion 12, so that the needle portion 122 goes over the protective portion 43B and comes into contact with the storage portion 12. Can be prevented.

上述したように本発明の第３の実施形態に係る注射器用容器１Ｂによれば、注射器１００から排出される流体を貯留部１２に安全に収容可能であり、また安価に製造できるとともに、高い生産性を有する。 As described above, according to the syringe container 1B according to the third embodiment of the present invention, the fluid discharged from the syringe 100 can be safely stored in the storage unit 12, can be manufactured at low cost, and is highly produced.

In the above-described example, the syringe container 1 has the insertion portion 11, the guide portion 21, the body portion 22, and the rubber stopper 23 separately configured, and the guide portion 21, the body portion 22, and the rubber stopper 23 are formed separately. The configuration for assembling the rubber together has been explained, but the present invention is not limited to this. For example, as shown in the insertion portion 11C according to the fourth embodiment shown in FIG. 9, the guide portion 21 and the body portion 22 are integrally molded with a resin material, and the rubber stopper 23 is arranged inside during the molding. There may be.

また、上述した例では、注射器用容器１は、ガイド部２１及び胴部２２を突起部３２ｂ及び窪み４１ｂの係合により一体に組み立てる構成を説明したがこれに限定されない。例えば、ガイド部２１の係合部３２の外周面に雄螺子部を設け、胴部２２の被係合部４１の内周面に雌螺子部を設け、これら螺子部の螺合によりガイド部２１及び胴部２２を組み立てる構成であってもよい。この他、本発明の要旨を逸脱しない範囲で種々変形実施可能である。
