この考案は輸液溶器用栓体、さらに詳しく言え
ば、たとえばリンゲル液等を患者に輸液するとき
に用いる輸液容器用の栓体に関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a stopper for an infusion container, and more specifically, to a stopper for an infusion container used when injecting Ringer's solution or the like into a patient.

を連続的に注入するようになつている。
As shown in FIG. 1, a stopper is attached to the lower end of an infusion container 1, such as a soft plastic bag or a hard plastic bottle, and an insertion needle inserted as shown by the dashed arrow is inserted into the lower end of the infusion container 1. , the infusion in the infusion container 1 is continuously injected into a patient (not shown).

内壁であつて、この中心に射出ゲートが位置し、
前記軸端壁３１はこの内壁２８に接触支持される
構造である。 This stopper has a hollow cylindrical shape, one axial end is open and communicates with the inside of the infusion container 1, and an opening 22A is formed in the axial end wall 22 located at the other axial end. Like the plug body 2, it has a hollow cylindrical shape, and its peripheral wall portion 32 is similar to the peripheral wall portion 21 of the plug body.
The shaft end wall 31 of the rubber plug 3 is embedded and supported within the other shaft end wall 22 of the plug body 2 to close the opening 22A. It's becoming like that. Note that the reference numeral 28 is a thin inner wall formed during injection molding, and the injection gate is located at the center of this wall.
The shaft end wall 31 has a structure in which it is supported in contact with the inner wall 28.
使用時に挿入針を破線矢印の方向に差し込むと

押し込まれてしまう事故がおこる欠点があつた。 When the insertion needle is inserted in the direction of the dashed arrow during use, it is normal for the insertion needle to penetrate the shaft end wall 31, break the inner wall 28, and reach the inside of the infusion container. In the case of a plug, if the insertion needle fails to penetrate the shaft end wall 31, a strong force is applied to the shaft end wall 31 in the axial direction, and the peripheral wall 32 supported by the plug body 2 is also pulled. There is a drawback that an accident may occur in which the rubber stopper 3 is pushed into the infusion container 1 and the entire rubber stopper 3 is pushed into the infusion container 1.

In order to achieve the above object, this device has a hollow cylindrical shape, is fixed to the infusion dispenser via a flange formed at one shaft end connected to the peripheral wall, and an opening is formed in the other shaft end wall. It has a hollow cylindrical shape with a bottom and has a stopper main body and one shaft end wall, the peripheral wall part of which is embedded and supported in the stopper main body, and the peripheral wall part is embedded in the other shaft end wall of the stopper main body. The rubber stopper is embedded and supported in the stopper body, and the stopper body is provided with a locking protrusion, whereby the rubber stopper is securely held in the stopper body.

FIG. 2 shows a first embodiment of this invention, in which the peripheral wall 21 of the stopper body 2A is
On the inside in contact with the peripheral wall 32 of the rubber stopper, for example, a thread, an independent ring, or a plurality of protrusions that are not continuous in the circumferential direction but are provided at approximately equal positions on the circumference, etc., in the radial direction. A locking protrusion 23 is formed that protrudes in the direction, and this locking protrusion 2
3 reliably prevents the rubber stopper 3 from being removed.

A locking protrusion 26 is formed on this flange portion 25 during insert molding in exactly the same manner as in the second embodiment described above to securely hold the flange portion 33 and thereby prevent the rubber stopper 3 from coming off. It is.

In any of the above embodiments, the locking protrusion formed on the stopper body is inserted into the rubber stopper or is insert-molded so as to be integrally intertwined with the stopper, and as a result, the rubber stopper is securely held in the stopper body. This has the effect of completely preventing an accident in which the rubber stopper separates from the stopper body and is pushed into the infusion container when the insertion needle is inserted. In addition, when the inserted needle is removed, the rubber stopper is securely held in the stopper body by the locking protrusion of the stopper body sinking into the rubber stopper, so that the rubber stopper is detached from the stopper body and inside the stopper. Accidents such as solution scattering can be completely prevented. Furthermore, since the shaft end wall of the rubber stopper is embedded and supported within the shaft end wall at the other end of the stopper body, the shaft end wall of the stopper main body is Therefore, it is possible to more reliably prevent the rubber stopper from coming off the stopper body when inserting and removing the insertion needle as described above.
