ための弁を備えた点滴容器に関するものである。BACKGROUND OF THE INVENTION In a conventional drip container, when the liquid medicine is completely filled, the container is emptied and then the air enters the tube. The present invention is provided with a valve for preventing the air from entering. The present invention relates to a drip container.

取る。そのようなことを避けようとして、特に患者の寝
込んだ夜間は看護婦の気苦労が大きい。When receiving an infusion at a hospital, it is often the case that neither the patient nor the nurse is aware that the infusion has been completed and the container has been emptied. If left as it is, air will enter the tube connected to the blood vessel, or blood will flow back into the tube and harden, making it more time consuming for the next injection. Nurses have a great deal of trouble trying to avoid this, especially at night when the patient falls asleep.
【０００４】本発明は、薬液の注入が完了しても、空気
がチューブに進入しない容器を提供することを目的とし
ている。[0004] An object of the present invention is to provide a container in which air does not enter the tube even after the injection of the chemical solution is completed.
【０００５】[0005]
【課題を解決するための手段】上記目的を達成するため
に、点滴容器内の底に、伏せたカップ状の弁を取り付け
る。In order to achieve the above object, a protruding cup-shaped valve is attached to the bottom of a drip container.
【０００６】この弁は容器内で浮くように、内容液より
小さい比重の材料で作るか（プラスチックはほとんど比
重が水より小さいのでプラスチックで作って問題はな
い）、弁の頂部に空気室を設けるかする。[0006] This valve is made of a material having a specific gravity smaller than the content liquid so that it floats in the container (plastic has almost no problem because it has a smaller specific gravity than water), or an air chamber is provided at the top of the valve. Do it.
【０００７】薬液が容器内に充分ある間は容器の底に接
触せず、弁の機能が働かないようにしておく。この間、
点滴注入が行なわれる。While the liquid medicine is sufficiently in the container, it does not contact the bottom of the container, so that the function of the valve is not operated. During this time,
Instillation is performed.
【０００８】注入完了直前になり容器内の液面が下がる

ブへの進入を遮断する。Immediately before the completion of the filling, when the liquid level in the container drops, the prone cup also lowers, and its edge contacts the bottom of the container. Then, a negative pressure is generated in the cup due to the suction force due to the weight of the drug solution in the tube, and the edge of the cup is brought into close contact with the soft bottom of the container, stopping the outflow of the drug solution and blocking air from entering the tube.

FIG. 1 is a cross-sectional view of the bottom of a drip container of the present invention, in which a medicinal solution has been filled and a drip is being injected. 1 is a drip container main body. 2 is a cup-shaped air shutoff valve which is turned down. 3 is a flat bottom made of a soft material. The material of the bottom is the same as that used in the conventional drip container, and is sufficiently soft. 4 is a projection for stopping the floating of 2. 5 is a needle for taking out a chemical solution inserted into the bottom of the container. The cup 2 needs to have such a height that the needle does not touch the ceiling.

【発明の効果】本発明は、以上説明したように構成され
ているので、以下に述べるような効果を奏する。Since the present invention is configured as described above, it has the following effects.

た血液がチューブ内に逆流するのを防ぐ。よって、看護
婦および患者の気苦労を軽減する。When the injection of the drip is completed, the valve is activated to stop the flow of the liquid and prevent air from entering the tube. It also prevents blood from flowing back into the tube. Thus, the burden of nurses and patients is reduced.
【００１３】また、構造が簡単であるために、安価に製
作することができる。Further, since the structure is simple, it can be manufactured at low cost.

くなり、よって薬液を無駄なく使える。[0014] Also, although there is still a usable chemical solution,
It is not necessary to take care and to terminate the injection prematurely, so that the drug solution can be used without waste.
