BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a drug solution container containing a drug solution to be mixed with an infusion solution.

[0002]

2. Description of the Related Art With the development of infusion related systems, it has become common to mix a drug solution with an infusion solution and infuse the solution intravenously. In that case, various chemical solutions (may be distilled water) filled in the chemical solution container are mixed with the above-mentioned infusion solution contained in an infusion solution container such as a bottle or a bag.

The bottle, which is an infusion container, is usually made of glass, and its opening is closed by a rubber stopper. The bag is made of resin and is sealed after containing the infusion solution. As the drug solution container, a glass ampoule or a resin twist ampoule is often used.

When mixing the drug solution filled in the drug solution container with the infusion solution in the bottle or bag, first, the drug solution container is opened. Then, the drug solution in the drug solution container is sucked by a syringe, and after suctioning, the drug solution is injected by piercing an injection needle connected to the barrel tip of the syringe into the stopper or bag of the bottle.

As described above, when a drug solution is mixed with an infusion solution by using a syringe, the drug solution is transferred from the drug solution container to the syringe and then transferred from the syringe to the infusion solution container. It will be mixed with the infusion solution in the bag.

[0006] Therefore, there is a risk that foreign substances may be mixed into the chemical liquid or contaminated by microorganisms in the transfer route, and therefore the transfer work should be as small as possible.
Moreover, in the transfer work using a syringe, since it is necessary to suck the drug solution from the drug solution container with the syringe and then inject it into a bottle or a bag, it may be time-consuming to perform such work. When aspirating from, it may be easy to mix foreign substances into the chemical solution.

[0007]

As described above, conventionally, when a drug solution in a drug solution container is mixed with an infusion solution, the drug solution is sucked with a syringe and then injected into the infusion solution container with the syringe. However, since the transfer work is increased, foreign substances may be mixed in or contaminated with the chemical liquid along the route, and the workability may be poor.

The present invention has been made under the above circumstances, and an object thereof is to provide a drug solution container capable of easily and reliably mixing a drug solution with an infusion solution.

[0009]

Means for Solving the Problems To solve the above problems, the present invention provides a drug solution container containing a drug solution to be mixed with an infusion solution, which has a container body formed of a flexible material in a hollow shape, this is the container body externally fitted needle connections for hand - Pa-like connecting portion is integrally formed, the connecting portion
The tip side of is formed in the sealing part that seals the connection part,
Is a broken part that breaks when the tip side of the above connection part is twisted.
Is formed .

[0010]

According to the above construction, since the injection needle can be connected to the connection portion of the opened drug solution container and the drug solution can be injected by piercing the injection needle into the infusion container, the drug solution is transferred to the syringe. Without being mixed with infusion.

The tip of the connecting portion 3 has a sealing portion 3b in order to prevent the chemical solution filled in the container body 2 from flowing out.
It is sealed by. Further, a breaking portion 3c which is formed in a constricted state is provided on the upper portion of the connecting portion 3 so that the connecting portion 3 can be easily broken without being blocked, and the upper portion of the connecting portion 3 is twisted by the breaking portion 3c. It is formed on the ridge 4.

As a means for molding the container body 2 and the connecting portion 3 of the chemical liquid container 1, for example, vacuum molding or blow molding is used, and when these are integrally molded,
As shown in FIG. 2A, the connecting portion 3 is in a state where the upper end is open.

The inside of the container body 2 molded in this way is filled with the chemical solution from the upper end opening of the connecting portion 3. After injecting the chemical liquid, the connection part 3 has a pair of pressing parts 5a for forming the sealing part 3b and a convex part 5b for forming the breaking part 3c as shown in FIG. 2 (b). It is sandwiched while being heated by the sealing mold 5.

As a result, the sealing portion 3b and the breakage portion 3c are formed in the connecting portion 3 as described above, and the sealing portion 3 is formed.
While the upper end of the connecting portion 3 is sealed by b,
The twisted portion 4 is formed by the broken portion 3c.

A cap 6 is attached to the connecting portion 3 of the liquid medicine container 1 thus sealed. As shown in FIG. 2 (c), the cap 6 has a hollow cap portion 6 a which is fitted onto the connecting portion 3, and a pair of cap portions 6 a projecting radially outward from the outer peripheral surface of the cap portion 6 a. Flange 6b
And a through hole 6c formed in the cap portion 6a.

In the cap 6, the twisting portion 4 is passed through the through hole 6c of the cap portion 6a, and the connecting portion 3 is formed.
