Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a drug container. More specifically, dry drugs such as powdered preparations, freeze-dried preparations, and solid preparations and their dissolved solutions are stored in a separated state, and the dried drug and the dissolved solutions are aseptically mixed in a container immediately before use. The present invention relates to a medicine container set with a communicating means for supplying as a liquid medicine.

2. Description of the Related Art Conventionally, in medical institutions such as hospitals, a dried drug contained in a drug container such as a vial is dissolved in distilled water, a saline solution, a solution such as glucose solution (including other drug solutions), and then an intravenous injection is made. It is used for In order to easily use in such a case, the vial containing the dry drug is connected in series to the flexible container containing the solution,
There has been proposed an infusion container or the like in which the two containers are aseptically communicated by puncturing the rubber stoppers of both containers with a puncture needle (referred to as a double-ended needle) having puncture portions at both ends of a hollow needle at the time of use ( Japanese Patent Publication No. 61-501129, JP-A 2-1
No. 277, Japanese Utility Model Laid-Open No. 63-135642, etc.).

The one disclosed in Japanese Patent Publication No. 61-501129 is that in which a capsule containing a drug container and a flexible container containing a solution are connected by a tube, which is provided in the tube. The medicine container and the flexible container are communicated with each other by the communication means so that the medicine and the solution are aseptically mixed. In addition, JP-A-2-1277
What is disclosed in the publication is that the capsule containing the drug container is connected to the mouth of the dissolution liquid container at its connecting portion, and the connecting means having the connecting sequence regulating means is interposed on the connecting portion side of the capsule. In, after the drug container is pierced by the communication means, the dissolution liquid container is pierced and the two containers are communicated, and the drug and the dissolution liquid are aseptically mixed,
The one disclosed in Japanese Utility Model Laid-Open No. 63-135642 is a cylindrical support ring that is detachably attached to the sealing portion at the mouth of the solution container, and a double-ended needle is attached to this support ring so that it can slide up and down. In addition, when the double-ended needle is slid downward, the lower needle body punctures the seal portion at the mouth of the dissolution liquid container.

[0004]

Among the above-mentioned conventional infusion containers, the one disclosed in Japanese Utility Model Laid-Open No. 63-135642 is an infusion container with a communicating means, and a vial which is a general distribution form of dry chemicals. It includes the one that is captured and integrated as it is. Further, those disclosed in Japanese Patent Publication No. 61-501129 and Japanese Patent Application Laid-Open No. 2-1277 are:
All of them are vials, which are a general distribution form of dry chemicals, and are integrated as they are, and in that sense, they are highly versatile. However, the special table Sho 61-501129
The infusion container of Japanese Patent Publication has a large number of parts, and it takes time to fold the breaking member by hand to open the passage. It has the drawback of being time consuming, and it is also difficult to achieve this.
The infusion container of -1277 is considerably improved in comparison with the infusion container of JP-A-61-501129 in respect of prevention of contamination of internal medicine and simplification of communication between the medicine container and the dissolution container. However, there are drawbacks in that the parts such as the communication order regulating means are complicated and the number of parts is large as a whole.
The infusion container of JP-A-3-135642 has a small number of parts and is relatively easy to operate, but requires a relatively large force for communication. After mixing the drug and the solution, the support ring and the double-ended needle are removed to dissolve the solution. Since it is necessary to invert the container and connect an infusion set etc. to the seal part at the mouth of the dissolution liquid container after removing the double-ended needle, it takes time and labor for operation, and there is a risk that the mixed drug solution will leak when the double-ended needle is removed. There is
It has drawbacks such as

The present invention has been made in view of the above circumstances, and is an improvement over the conventional drug container, which is easy to operate, hassle-free, has a small number of parts, and is aseptically mixed with a solution. An object of the present invention is to provide a drug container set provided with a communication means that can be used.

[0006]

In order to solve the above-mentioned problems, the present invention provides a drug comprising a bottomed cylindrical container body having a reduced diameter mouth portion and a rubber stopper for closing the mouth portion of the container body. An assembly comprising a container, a communication means provided at the mouth of the medicine container, and a cover member for protecting the communication means, the communication means being attached to a body and extending vertically along an outer wall thereof. An airtightly slidable support part, a locking part that is continuous with the support part and has an engaging projection that engages with the outer wall of the mouth part in the lower part, and is fixed to the upper part of the locking part via a partition wall. Also, a drug container set comprising a double-ended needle and including a communicating means configured such that the drug container is communicated with the outside by the communicating means when the communicating means is moved downward.

[0007]

According to the above construction, when the cover member is removed from the communication means and the upper puncture needle of the double-ended needle is applied to the rubber stopper at the mouth of the dissolution liquid container and pushed down, the communication means slides downward. Then, the rubber stopper at the mouth of the drug container is pierced by the lower puncture needle of the double-ended needle, and the inside of the drug container and the drug solution passage of the double-ended needle communicate with each other. On the other hand, the rubber stopper at the mouth of the dissolution liquid container is pierced by the upper puncture needle of the double-ended needle, and the inside of the dissolution liquid container communicates with the drug solution passage of the double-ended needle. Communicate with the container.
