Description

本発明は、ポートを備え、内部に医療用液体が収納された医療用容器に関する。 The present invention relates to a medical container provided with a port and containing a medical liquid inside.

薬液容器や輸液容器等の医療用容器は、収納している液体の排出、容器内への薬剤の混注などのためにポートを備えている。ポートには、弾性材料（ゴム材、エラストマー材）からなり、医療用具（例えば、輸液セットの接続針、注射針）の穿刺が可能な栓体が収納されている。また、ポートには、内側に栓体を保持するキャップを備えるものが一般的である。さらに、ポートには、栓体の上面を覆うように保護シートが剥離可能に固着されているものがある。この保護シートは、栓体の使用前の汚染防止、使用済みかどうかの確認指標として機能する。このような剥離可能なシートを備えるものとしては、特許第５１２２８７８号公報（特許文献１）、実公平３−２４１８６号公報（特許文献２）が例示される。 Medical containers such as chemical containers and infusion containers are provided with ports for discharging the stored liquid and for mixed injection of chemicals into the container. The port is made of an elastic material (rubber material, elastomer material) and contains a plug body capable of puncturing a medical device (for example, a connecting needle of an infusion set, an injection needle). Further, the port is generally provided with a cap for holding the plug inside. Further, some ports have a protective sheet detachably fixed so as to cover the upper surface of the plug. This protective sheet functions as a contamination prevention before use of the plug and as a confirmation index of whether or not it has been used. Examples of those provided with such a peelable sheet include Japanese Patent No. 5122878 (Patent Document 1) and Japanese Patent Application Laid-Open No. 3-24186 (Patent Document 2).

特許第５１２２８７８号公報Japanese Patent No. 5122878 実公平３−２４１８６号公報Jitsufuku 3-24186 Gazette

最近、複数の病院で発生した輸液剤への異物混入による被害が報道等で報告されている。これは、保護シート上から針で穿刺し、医療用容器内に異物を混入した犯行とされている。輸液剤の保護シートが剥離されていない状態では、未使用であると医療従事者は考える。このため、投与時に、保護シートへの針刺しの有無の確認、保護シート剥離後の栓体への針刺しの有無の確認は、行われていない。また、上記の保護シートへの針刺しの有無の確認自体も容易ではない。投与時に、医療従事者が、混注の事実に気付くことは困難である。
本願発明の目的は、医療用容器への穿刺部材による穿刺の確認が容易であり、混注された可能性があることを容易に認識することができる医療用容器を提供するものである。 Recently, reports of damage caused by foreign matter mixed in infusions that occurred in multiple hospitals have been reported. This is allegedly a crime of puncturing a protective sheet with a needle and mixing a foreign substance into a medical container. Healthcare professionals consider the infusion solution to be unused when the protective sheet has not been peeled off. Therefore, at the time of administration, the presence or absence of needle sticks in the protective sheet and the presence or absence of needle sticks in the plug after peeling of the protective sheet have not been confirmed. In addition, it is not easy to confirm the presence or absence of needle sticks in the protective sheet. At the time of administration, it is difficult for healthcare professionals to notice the fact of mixed injection.
An object of the present invention is to provide a medical container in which it is easy to confirm puncture by a puncturing member into a medical container and it is possible to easily recognize that there is a possibility of mixed injection.

As a result, the space between the tubular opening 22 and the sealing member 7 is liquid-tight.

弾性シール部材８は、医療用具、例えば、穿刺部材１０（具体的には、薬液排出用針管）の穿刺が可能なものが用いられており、特に、穿刺部材の抜去後に刺通部がシールされるものであることが好ましい。弾性シール部材８は、弾性材料により形成されている。弾性シール部材８の形成材料としては、シリコーンゴム、イソプレンゴム、ブチルゴム、天然ゴム等の各種ゴム類、ポリウレタン、ポリアミドエラストマー、ポリブタジエン、軟質塩化ビニル等の各種樹脂が用いられる。 As the elastic sealing member 8, a medical device, for example, a puncturing member 10 (specifically, a needle tube for discharging a drug solution) is used, and in particular, the puncturing portion is sealed after the puncturing member is removed. It is preferable that it is one. The elastic sealing member 8 is made of an elastic material. As the material for forming the elastic sealing member 8, various rubbers such as silicone rubber, isoprene rubber, butyl rubber and natural rubber, and various resins such as polyurethane, polyamide elastomer, polybutadiene and soft vinyl chloride are used.

そして、本発明の医療用容器１では、図１ないし図４および図６に示すように、ポート３は、医療用具接続可能部８の上面を覆うように設けられた被包部材５を備える。被包部材５は円柱体を薄い輪切りにしたような形状となっている。被包部材５は、穿刺部材１０による穿刺後、穿刺部材１０とともにポート３より離脱する。また、被包部材５は、ポート３からの離脱後、再装着が不能もしくは困難であることが好ましい。この実施例では、被包部材５は、円柱面が円柱体中心軸方向に若干圧縮した状態にて、ポート３に装着されており、ポート３からの離脱後、圧縮前形態への復元のため、若干拡張する。このため、ポート３への再装着は、不能もしくは困難となっている。 Then, in the medical container 1 of the present invention, as shown in FIGS. 1 to 4 and 6, the port 3 includes an encapsulating member 5 provided so as to cover the upper surface of the medical device connectable portion 8. The encapsulating member 5 has a shape like a thin round slice of a cylinder. After being punctured by the puncture member 10, the encapsulating member 5 is separated from the port 3 together with the puncture member 10. Further, it is preferable that the encapsulating member 5 cannot or is difficult to be reattached after being detached from the port 3. In this embodiment, the encapsulating member 5 is attached to the port 3 in a state where the cylindrical surface is slightly compressed in the direction of the central axis of the cylindrical body, and is restored to the pre-compressed form after being separated from the port 3. , Expand slightly. For this reason, it is impossible or difficult to reattach to the port 3.

この実施例では、被包部材５は、ポートに３装着された板状部材により構成されている。そして、被包部材５は、内部に医療用具接続可能部（弾性シール部材）８を収納したキャップ９に離脱可能に装着されている。特に、この実施例のものでは、板状の被包部材５は、キャップ９の上端開口に、上端開口を封鎖するように装着されている。このため、ポート３の外部からは、弾性シール部材８の上面が視認できないものとなっているとともに、被包部材５により、弾性シール部材８の上面（医療用具接続部の表面）は覆われ、弾性シール部材８の汚染が防止されている。 In this embodiment, the encapsulating member 5 is composed of a plate-shaped member 3 mounted on the port. Then, the encapsulating member 5 is detachably attached to the cap 9 in which the medical device connectable portion (elastic seal member) 8 is housed. In particular, in this embodiment, the plate-shaped encapsulating member 5 is attached to the upper end opening of the cap 9 so as to close the upper end opening. Therefore, the upper surface of the elastic seal member 8 cannot be visually recognized from the outside of the port 3, and the upper surface of the elastic seal member 8 (the surface of the medical device connection portion) is covered by the encapsulating member 5. Contamination of the elastic sealing member 8 is prevented.

そして、この実施例の医療用容器１では、図９に示すように、被包部材５の上面から穿刺部材１０（図９に示すように針管）の刺入が可能である。しかし、被包部材５を刺通した後、穿刺部材１０（針管）を医療用容器１より抜去すると、図１０および図１１に示すように、被包部材５と穿刺部材１０間の摩擦力により、被包部材５は、穿刺部材１０に保持され、ポート３より離脱する。なお、被包部材５がポート３に若干圧縮して装着されていれば、摩擦力が増すものとなる。そして、上記の被包部材５のポート３からの離脱により、通常であれば、存在しているはずの被包部材５がなくなり、弾性シール部材８の上面が露出する状態となる。被包部材５の欠落、弾性シール部材８の露出を確認することにより、医療用容器への混注の可能性を容易に認識することができ、そのような可能性のある医療用容器の使用を防止することができる。 Then, the medical container 1 of this embodiment, as shown in FIG. 9, it is possible to insertion of the piercing member 10 from the upper surface of the encapsulated member 5 (the needle tube as shown in FIG. 9). However, when the puncture member 10 (needle tube) is removed from the medical container 1 after the encapsulation member 5 is pierced, as shown in FIGS. 10 and 11, the frictional force between the encapsulation member 5 and the puncture member 10 causes the puncture member 10 (needle tube) to be removed. , The encapsulating member 5 is held by the puncture member 10 and detaches from the port 3. If the encapsulating member 5 is slightly compressed and mounted on the port 3, the frictional force will increase. Then, due to the detachment of the encapsulating member 5 from the port 3, the encapsulating member 5 that would normally exist disappears, and the upper surface of the elastic sealing member 8 is exposed. By confirming the lack of the encapsulating member 5 and the exposure of the elastic sealing member 8, the possibility of mixed injection into the medical container can be easily recognized, and the use of the medical container having such a possibility can be recognized. Can be prevented.

また、被包部材としては、図７に示すようなものであってもよい。図７に示すポート３ａでは、上述したポート３と同様に、医療用具接続可能部（弾性シール部材）８の上面を覆うように設けられた被包部材５ａを備える。被包部材５ａは、穿刺部材１０による穿刺後、穿刺部材１０とともにポート３より離脱する。また、被包部材５ａは、ポート３ａからの離脱後、再装着が不能もしくは困難となっている。この実施例では、被包部材５ａは、上述したものと同様に、若干圧縮した状態にて、ポート３ａに装着されており、ポート３ａからの離脱後、圧縮前形態への復元のため、若干拡張する。このため、ポート３ａへの再装着は、不能もしくは困難となっている。 Further, the encapsulating member may be the one shown in FIG. 7. The port 3a shown in FIG. 7 includes an encapsulating member 5a provided so as to cover the upper surface of the medical device connectable portion (elastic seal member) 8 in the same manner as the port 3 described above.

Further, the encapsulating member 5a cannot or is difficult to be reattached after being detached from the port 3a. In this embodiment, the encapsulating member 5a is attached to the port 3a in a slightly compressed state in the same manner as described above, and is slightly compressed to restore the pre-compressed form after being detached from the port 3a. Expand. For this reason, it is impossible or difficult to reattach to the port 3a.

この実施例では、被包部材５ａは、ポートに３ａに装着された板状部材により構成されている。特に、この実施例のものでは、板状の被包部材５ａは、キャップ９の上端開口より若干下方、言い換えれば、弾性シール部材８方向に位置し、かつ、弾性シール部材８の上面に当接している。この実施例の被包部材５ａも弾性シール部材８の上面全体を被覆しており、弾性シール部材８の上面が視認できないものとなっているとともに、被包部材５ａにより、弾性シール部材８の上面（医療用具接続部の表面）は覆われ、弾性シール部材８の汚染が防止されている。 In this embodiment, the encapsulating member 5a is composed of a plate-shaped member mounted on the port 3a. In particular, in this embodiment, the plate-shaped encapsulating member 5a is located slightly below the upper end opening of the cap 9, in other words, in the direction of the elastic sealing member 8, and is in contact with the upper surface of the elastic sealing member 8. ing. The encapsulating member 5a of this embodiment also covers the entire upper surface of the elastic sealing member 8, so that the upper surface of the elastic sealing member 8 cannot be visually recognized, and the encapsulating member 5a covers the upper surface of the elastic sealing member 8. (The surface of the medical device connection portion) is covered to prevent contamination of the elastic sealing member 8.
