上記特許文献１および特許文献２のものは、連通規制部の破損操作を行うことなく、輸液セットの薬剤排出用針管を穿刺しても薬剤が流出することはなく、安全なものとなっている。同様に、特許文献３のものでは、離脱抑制用弱シール部７が未剥離状態では、排出口３３内への薬剤排出用針管の侵入ができず、輸液セットの薬剤排出用針管を穿刺しても薬剤が流出することはなく、安全なものとなっている。しかし、特許文献１のものでは、排出ポート内が、軸方向に２室に区分されており、薬剤排出用針管は、その１室のみに穿刺可能なものとなっている。このため、排出ポートにおける薬剤排出用針管の穿刺可能部位が小さく、穿刺作業時における位置決めなどの穿刺作業が難しいものとなっていた。また、特許文献２および３のものでは、特許文献１のものに比べて、排出ポートにおける薬剤排出用針管の穿刺可能部位は通常の大きさのものとでき、穿刺作業時における位置決めなどの困難性はない。しかし、特許文献２の図２に示すものでは、排出ポート３内の薬剤を容器本体内に流入させるためには、破断操作を必要とする。特許文献３のものでは、特許文献２のような、排出ポート３の破断操作は不要であるが、穿刺した針管により、ある程度の強さにより、閉塞部材４を押圧しなければならなかった。
そこで、本発明は、排出ポートの上方に設けられた剥離可能な弱シール部により形成された区画部により形成された小室を有し、排出ポート内若しくは小室内に薬剤が収納された医療用容器において、小室と排出ポート間の薬剤流通を防止し、かつ、区画部が未剥離状態にて薬剤が投与されることがなく、さらに、区画部を剥離後において、薬剤排出用針管を穿刺することにより、容易に、排出ポート内を容器本体内と連通させることができる医療用容器を提供するものである。 The above-mentioned Patent Document 1 and Patent Document 2 are safe because the medicine does not flow out even if the medicine discharge needle tube of the infusion set is punctured without damaging the communication restricting portion. . Similarly, in Patent Literature 3, when the weak seal portion 7 for suppressing detachment is not peeled, the medicine discharge needle tube cannot enter the discharge port 33, and the drug discharge needle tube of the infusion set is punctured. However, the drug does not flow out and is safe. However, in Patent Document 1, the inside of the discharge port is divided into two chambers in the axial direction, and the needle tube for discharging the medicine can be punctured only in that one chamber. For this reason, the site | part which can puncture the needle tube for medicine discharge | emission in a discharge port is small, and puncture operations, such as positioning at the time of a puncture operation, were difficult. Also, in Patent Documents 2 and 3, compared to Patent Document 1, the punctureable portion of the drug discharge needle tube in the discharge port can be of a normal size, and positioning is difficult during puncture work. There is no. However, in the case shown in FIG. 2 of Patent Document 2, a breaking operation is required to allow the medicine in the discharge port 3 to flow into the container body. With the thing of patent document 3, the fracture | rupture operation of the discharge port 3 like patent document 2 is unnecessary, but the obstruction | occlusion member 4 had to be pressed by a certain amount of strength with the punctured needle tube.
Therefore, the present invention has a small chamber formed by a partition portion formed by a peelable weak seal portion provided above the discharge port, and a medical container in which a medicine is stored in the discharge port or the small chamber In this case, the medicine flow between the small chamber and the discharge port is prevented, the medicine is not administered when the partition part is not peeled off, and the medicine discharge needle tube is punctured after the partition part is peeled off. Thus, a medical container capable of easily communicating the inside of the discharge port with the inside of the container body is provided.

In the state of contact with the needle movement intrusion member 4f, the needle tube entry inhibiting portion 44 is in contact with or close to the upper surface of the sealing portion 33 (in this embodiment, contact). For this reason, in the medical container having the discharge port 3k of this embodiment, the connection (insertion) of the drug discharge needle tube to the discharge port 3k before the separation of the partition part 7 is prevented.

The needle tube receiving portion 60a is a hollow portion and can accommodate the distal end portion of the drug discharge needle tube. Further, in the medicine outflow inhibition part 60, the needle tube receiving part 60a has a large inner diameter at the lower end part, and forms a guiding part 60b for a medicine discharge needle pipe (not shown). In addition, the guide portion 60b of the medicine outflow inhibition portion 60 includes a tapered portion that decreases in diameter toward the tip, and a seal that can annularly contact the upper surface of the tapered portion with the outer surface below the side port of the drug discharge needle tube. A formable part is formed. In other words, the medicine discharge needle tube can enter the needle tube receiving portion 60a up to a position where the side port is above the seal-formable portion, and the seal-formable portion and the outer surface of the portion slightly below the side port Prevents the drug from flowing out from the side port by contacting the ring.
Further, the needle tube receiving portion 60a is such that the tip of the drug discharge needle tube cannot reach the inner surface of the upper end of the needle tube receiving portion 60a. For this reason, the tip of the penetrating drug discharge needle tube does not come into strong contact with the inner surface of the needle tube receiving portion 60a, and is not damaged during operation.

また、薬剤流出阻害部は、上記のタイプのものに限定されるものではなく、例えば、図３２に示す排出ポート３ｕが備えている薬剤移動阻止部材４ｍのようなタイプのものであってもよい。
この実施例の薬剤移動阻止部材４ｍにおける薬剤流出阻害部６１は、下端が開口した針管受入部６１ａと、針管受入部６１ａの下端開口を封止しかつ薬剤排出用針管による刺通が可能なシール部材６１ｂとを備えている。針管受入部６１ａは、ほぼ同一内径にて所定長延びる内腔部下部と、先端方向に向かって縮径する内腔部上部を備えている。なお、針管受入部６１ａは、その全体が、下端より先端方向に向かって縮径するものであってもよい。そして、針管受入部６１ａの下端開口は、シール部材６１ｂによりシールされており、針管受入部６１ａ内は、空隙である内腔部６１ｃとなっている。そして、シール部材６１ｂは、薬剤排出用針管により刺通可能であり、かつ、少なくとも、薬剤排出用針管の側口の全体が、内腔部６１ｃ内となる位置まで、侵入可能なものとなっている。さらに、この実施例のものでは、シール部材６１ｂは、刺通された薬剤排出用針管の側面と環状に接触し、ほぼ液密状態を形成できるものであることが好ましい。さらに、シール部材６１ｂは、刺通された薬剤排出用針管の抜去後において、刺通部（穿刺孔）より薬剤が、内腔部６１ｃ内への流入を阻害できる程度の再シール性を有することが好ましい。また、シール部材６１ｂは、薬剤排出用針管による刺通抵抗があまり高くないものであることが好ましい。 Further, the drug outflow inhibition part is not limited to the above type, and may be of a type such as a drug movement blocking member 4m provided in the discharge port 3u shown in FIG. .
