が煩雑で組み立てに時間がかかる。 In recent years, in the field of infusions that supply nutrients and drugs directly into a patient's blood, it has become common practice to mix many types of preparations and infuse them through the same vein, as seen in high-calorie infusion therapy. I'm getting old. Mixing of these preparations is done immediately before use to ensure compatibility and stability, but as shown in Figure 1, the liquids drawn out from multiple preparation containers are combined into one bottle and introduced into a plastic bag. is,
Mixing methods are widely used. At this time, the tubes connected to each container are combined into one tube using one or more Y-shaped or three-pronged multi-tube connectors 1, and then introduced into the bag. Further, in order to mix small amounts of ingredients such as antibiotics and vitamins, a mixing spout 2 equipped with a lid made of an elastic material is provided in the middle of the tube. Therefore, when these preparation containers, tubes, connectors, mixing spouts, etc. are set together, the number of components is large, operations are complicated, and assembly takes time.

容易に混合することができる。 The present invention improves the above-mentioned drawbacks by integrating the connector and the mixed spout. Furthermore, with conventional connectors, it was difficult to provide three or more liquid inlets in one piece, but with the present invention, four or more liquid inlets can be provided in one piece. , a wide variety of formulations can be mixed simply and easily.

り、好ましい。 The connector of the present invention is one in which a plurality of liquid inlets, a single liquid outlet, and a mixed injection port are integrally provided. FIG. 2 is a perspective view showing an example of the connector of the present invention, and FIG. 3 is a sectional view. 1 is a connector body, 2 is a mixed injection port, 2' is a lid, 3 is a liquid inlet, and 4 is a liquid outlet. As shown in the figure, the liquid inlet and the liquid outlet are provided in opposite directions to each other, and the liquid inlets are provided in a horizontal row parallel to each other. Further, the mixed injection port 2 is a port for injecting a medicinal solution using a syringe, and is provided at the end of the liquid passage 5 of the connector body in the same direction as the liquid passage. As a result, even if the injection needle is inserted deeply into the liquid passage 5 from the mixed injection port, the needle tip will not hit the wall of the connector, and the amount of insertion is made so that the tip of the needle is near the liquid outlet 4. There is an advantage that the liquid can be mixed and injected effectively by adjusting the . In other words, if the mixed injection port is provided on the side, the core pin for forming the passage 5 connecting the liquid inlet and the liquid outlet can be pulled out from the mixed injection port when molding the connector using a mold. This allows for integral molding.
On the other hand, if there is no co-injection port in FIG. 2, it is difficult to form the passage 5 and cannot be integrally formed. Even if the number of liquid inlets is large (for example, four or more), it can be easily molded, which is preferable.
液導入口及び導出口は通常は円筒状であるが、
チユーブを接続するために必要に応じて溝や突起
あるいはネジなどを設けてもよい。 The liquid inlet and outlet are usually cylindrical, but
Grooves, protrusions, screws, etc. may be provided as necessary to connect the tubes.
本考案のコネクターは、材質は特に限定されな
いが、各種のプラスチツクを用いるのが、成形の
容易さ、経済性などの点で有利である。 Although the material of the connector of the present invention is not particularly limited, it is advantageous to use various types of plastics in terms of ease of molding and economy.
以上述べたように、本考案の多管コネクターは
混注口が一体に設けられているので、使用上便利
であるだけでなく、混注口を設けることによつて
一体成型が可能となり、さらに混注操作を安全に
効果的に行うことができるので、実用上きわめて
有用なものである。 As mentioned above, the multi-tube connector of the present invention is not only convenient to use because it has an integrated mixed injection port, but also allows for integral molding by providing a mixed injection port, which further improves the mixed injection operation. can be carried out safely and effectively, making it extremely useful in practice.
