を持上げ、落差による液圧を利用して内容液を空瓶へ移
注している。In the medical field, when transferring the contents between glass bottles, a combination of a connecting tube with hollow needles at both ends (called an extension tube) and two air needles or a liquid passage hole and an air hole are used. Transfer needles are widely used to pierce the caps of two glass bottles, lift one of the bottles, and use the hydraulic pressure caused by the head to transfer the liquid content into an empty bottle.

しかしガラス瓶から柔軟な空袋へ液体を移注しようとす

ス瓶のような空間がないから、落差による液圧だけでは
ガラス瓶の内容液は空袋へ移行しない。However, when trying to transfer liquid from a glass bottle to a flexible empty bag, the inner surface of the flexible empty bag is in close contact with each other under atmospheric pressure and there is no space like a glass bottle. will not be transferred to an empty bag.

うにしたのである。In this invention, a bottle needle having a liquid passage hole and an air hole and a hollow needle having only a liquid passage hole are made integrally or separately, the liquid passage holes of both needles are made to communicate with each other, and the air hole of the bottle needle is connected to the pump. A filter and a check valve are installed in the flow path, and a bottle needle and a hollow needle are inserted through their respective spouts, and the glass bottle and empty bag are connected through the liquid passage hole, and external air is supplied by pump operation. This created a positive pressure inside the glass bottle, and this positive pressure forced the liquid inside the glass bottle to be transferred smoothly into an empty bag whose inner surface was tightly sealed.

げその側面に開口させて開口部に逆止弁６を装入する。In the embodiment shown in FIGS. 1 and 2, 1 is a bottle needle having a liquid passage hole 2 and an air hole 3. A hollow needle 5 is connected in the opposite direction to a grip part 4 provided at the base. from the grip part 4 to the hollow needle 5
The air hole 3 is bent at the grip portion 4 and opened on the side thereof, and the check valve 6 is inserted into the opening.

この逆止弁は可撓材製の半球面を内側を凸にしてその凸
部に切筋７を切った簡単なものを用いる。This check valve uses a simple hemispherical surface made of a flexible material with a convex inner side and a cut line 7 cut in the convex portion.

８は空気孔３の入口に結合した接手管で、フィルター９
を内蔵しかつ鍔１１を有する芯管１０に結合する。8 is a joint pipe connected to the inlet of the air hole 3, and a filter 9
It is coupled to a core tube 10 having a built-in flange 11.

１２は芯管１０に接続した可撓材製有底筒体のポンプで
、底面に小孔１３をあけると共に周面を蛇腹状に屈曲さ
せて伸縮自在を作る。Reference numeral 12 denotes a bottomed cylindrical pump made of a flexible material connected to the core tube 10, with a small hole 13 in the bottom and the circumferential surface bent in a bellows shape to make it expandable and retractable.

第２図において、１４は輸液を入れて口栓１５を施こし
たガラス瓶、１６は２つの細小な口栓１７，１８を有す

に刺通した公知の空気針である。In Fig. 2, 14 is a glass bottle containing an infusion solution and a spout 15, 16 is a synthetic resin-type flexible empty bag having two small spouts 17 and 18, and 19 is the spout of this empty bag. 18
This is a well-known pneumatic needle pierced through the air needle.

本考案の一実施例は以上の構成からなり、ガラス瓶１４

袋１６の内部を大気に連通させる。One embodiment of the present invention has the above-mentioned configuration, and has a glass bottle 14.
When attempting to transfer the infusion into the empty bag 16, hold the handle 4 and insert the bottle needle 1 and the hollow needle 5 into the spout 15.1, respectively.
7 to connect the glass bottle 14 and the empty bag 16 at the liquid passage hole 2, and the air needle 19 is pierced through the other mouth plug 18 of the empty bag to communicate the inside of the empty bag 16 with the atmosphere.

以上の準備が終ると鍔１１をもって筒底の小孔１３を親
指で押え、ポンプ１２を圧縮して内部の空気を芯管１０
へ送出す。When the above preparations are completed, hold the flange 11 and press the small hole 13 in the bottom of the cylinder with your thumb, compress the pump 12 and pump the air inside into the core tube 10.
Send to.

この空気はフィルター９を通過して除菌されたのち接手
管８を流れ、この時逆止弁６はポンプ１２からの空気流
に対して切筋７を開くので、ポンプの空気は瓶針の空気
”ＪＬ３からガラス瓶１４へ送込まれる。This air passes through the filter 9 and is sterilized, and then flows through the joint tube 8. At this time, the check valve 6 opens the incisor 7 against the air flow from the pump 12, so that the air from the pump flows through the bottle needle. Air is sent from JL3 to the glass bottle 14.

次にポンプ１２の底面から親指を離して小孔１３を開く
とポンプ１２は自己の弾力で伸長して外部の空気をポン
プ１２の中へ流入させ、この時逆止弁６は上方からの空
気流に対して切筋７を閉じるのでガラス瓶内の空気は逆
流しない。Next, when you remove your thumb from the bottom of the pump 12 and open the small hole 13, the pump 12 expands by its own elasticity and allows outside air to flow into the pump 12. At this time, the check valve 6 opens the small hole 13. Since the cut line 7 is closed against the flow, the air inside the glass bottle does not flow back.

このようなポンプ１２の圧縮と伸長を繰返して外部の空
気を次々と接手管８へ送込み、この空気をフィルター９

空袋１６へ流入し、これに伴って空袋内の空気は空気針
１９から放出され、ガラス瓶１４から内面が密着した空
袋１６への輸液の移注は順調に行われる。By repeating the compression and expansion of the pump 12, external air is sent into the joint pipe 8 one after another, and this air is passed through the filter 9.
As the air inside the glass bottle is sterilized and sent to the glass bottle 14, the air inside the glass bottle is gradually pressurized to positive pressure, and the infusion liquid in the glass bottle receives this positive pressure, so it is forcibly sent to the liquid passage hole 2 and emptied. The air in the empty bag is discharged from the air needle 19, and the infusion fluid is smoothly transferred from the glass bottle 14 to the empty bag 16 whose inner surface is in close contact.
