Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interconnectable infusion container. More specifically, the present invention relates to an infusion container that can be used by connecting two containers so that the containers are in fluid communication with each other and the drug solutions contained therein can be mixed and used.

[0002]

2. Description of the Related Art Glucose infusion and amino acid infusion are preferably administered as a mixture from a nutritional point of view, but the mixture may be denatured by autoclave sterilization, and may be altered over time during storage. Is known to do. Therefore, infusion solutions that cause inconvenience when such a mixture is autoclaved or stored are conventionally stored separately in bottles, and the solution in each bottle is set prior to use. Etc. were used to transfer and mix in one bottle or bag. However, this method not only requires many containers and equipment such as bottles or bags and infusion sets before mixing,
It had the drawback of requiring extremely careful handling to perform the transfer and mixing operations aseptically.

Therefore, as a solution to the above problem, the present applicants have already characterized that the flexible bag is partitioned into a plurality of chambers by partitioning portions, and the partitioning portions are provided with openable communication means. Has been proposed (JP-A-57-52455). Then, after that, many proposals have been made to apply the technical idea of the infusion bag disclosed in JP-A-57-52455 (JP-A-63-19149, JP-A-4-97751, and JP-A-4-97751). JP-A-5-31153, JP-A-5-1115
24, etc.).

JP-A-63-19149 and JP-A-4
-97751 and JP-A-5-31153 disclose a partition strip that can be peeled by pressing, and JP-A-63-19149 discloses a synthetic resin multilayer sheet. Is a medical container characterized by being partitioned by a peelable adhesive part, and is disclosed in Japanese Patent Application Laid-Open No. 4-97751, a multi-layer film having a peel strength between two layers of 300 to 800 g / 15 mm. A medical bag having a partition portion fused to the bag film via the. Further, the one disclosed in Japanese Patent Application Laid-Open No. 5-31153 is characterized in that a partition part that is rupturable by pressing is formed by heat welding on a bag-shaped container made of a flexible synthetic resin having a micro layer separation structure. It is a container. On the other hand, JP-A-5-11152
The one disclosed in Japanese Patent Publication No. 4 has a connector portion provided in a partition strip portion similar to that in Japanese Patent Application Laid-Open No. 57-52455, and the connector portion can be blocked in a passage crossing hole portion provided in a communication passage. A movable core having a through hole in the passage direction is rotatably fitted therein.

[0005]

However, in the above-mentioned Japanese Patent Application Laid-Open No. 63-19149, which uses weakly adhesive partitioning strips so that the entire partitioning strips communicate with each other, they are separated by the partitioning strips. In order to prevent unintentional communication between the two chambers, it is necessary to separately tighten the partition band using a clamp or the like, which is a problem. In addition, JP-A-57-52
No. 455, etc., in which a communication means is separately provided in the partition band portion, the number of parts is large, and since the chamber on the mixing side needs to be formed large in order to facilitate mixing, the container becomes large accordingly. It has drawbacks such as The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a compact infusion container capable of aseptically mixing a plurality of drug solutions, which has a simple structure and does not require a clamp or the like.

[0006]

In order to solve the above-mentioned problems, the present invention is a closed container having upper and lower mouths, respectively, and the upper and lower mouths are provided with coupling means, respectively. In addition, a communication means is provided in one of the mouth portions, and the infusion container having a structure in which the coupling means of the one mouth portion and the coupling means of the other mouth portion can be coupled to each other is adopted. Here, in order to connect the upper mouth portion and the lower mouth portion to each other, for example, one of the mouth portions is provided with a communicating means with a female coupling means, and the communicating means is easily removable and sealed. It may be protected by a member and a male coupling means may be provided at the other mouth. In this case, for example, the communication means is constituted by a hollow puncture needle having a plate-shaped hub at its proximal end, a rubber cap is attached to the puncture needle, and the hub is provided with a female mold extending in the blade tip direction of the puncture needle. Providing coupling means,
It is preferable that the male coupling means side includes a tubular conduit closed with a thin film which can be easily pierced by the communicating means, and the male coupling means is provided on the outer wall of the conduit. The female coupling means comprises an engaging arm extending parallel to the puncture needle and a hook protruding inward from the tip of the coupling arm, and the male coupling means is an annular fitting formed on the outside of the tubular conduit. You may comprise with a protrusion.

[0007]

With the above construction, the plurality of infusion containers of the present invention can be connected to each other and used for infusion therapy. That is, FIG. 3 shows a state in which the _two infusion containers C ₁ and C ₂ of the present invention are interconnected. First, two infusion containers C ₁ and C ₂ are prepared, and the upper mouth portion 101 of the infusion container C ₁ is prepared.
The sealing members of both containers C ₁ and C ₂ are removed leaving the sealing member 701 of the infusion container C ₂ and the puncture needle 3 of the upper mouth 102 of the infusion container C ₂ is removed.
When the rubber cap is removed from 02 and the thin film (not shown in the figure) of the lower mouth 201 of the infusion container C ₁ is punctured, both containers C ₁ and C ₂ are in fluid communication with each other via the puncture needle 302. male coupling means 601 and the infusion container C ₂ female coupling means 402 of the infusion container C ₁ is engaged, both containers C
₁ and C ₂ are interconnected. Next, one infusion container, for example, the drug solution S _{1 of} C ₁ is transferred to the other infusion container C ₂ , and the drug solutions S ₁ and S ₂ contained in both containers C ₁ and C ₂ are mixed well, When the hanger hole 771 of the sealing member 701 of the container C ₁ is hung on the hanger H and the infusion set IS is connected to the lower opening 202 of the infusion container C ₂ , the mixed drug solution can be administered to the patient.
