DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medicine container. More specifically, dry drugs such as powdered preparations, freeze-dried preparations, and solid preparations, and their solutions are stored in a separated state, and immediately before use, the dry drugs and the solution are mixed aseptically in a container. The present invention relates to a medicine container set with communication means for supplying a medicine as a liquid medicine.

[0002]

2. Description of the Related Art Conventionally, in a medical institution such as a hospital, a dry drug contained in a drug container such as a vial is dissolved in a dissolving solution (including other drug solutions) such as distilled water, saline, glucose solution, etc., and is injected by infusion. Used for In such a case, the vial containing the dried drug is connected in series to the flexible container containing the dissolving solution so that it can be used easily,
There has been proposed an infusion container or the like in which the rubber stoppers of both containers are punctured with a puncture needle having a puncture portion at each end of the hollow needle at both ends (referred to as a double-ended needle) to aseptically communicate these two containers ( JP-T-61-501129, JP-A-2-1
No. 277, Japanese Utility Model Application Laid-Open No. 63-135624, etc.).

[0003] Japanese Unexamined Patent Publication (Kokai) No. 61-501129 discloses a capsule in which a capsule containing a medicine container and a flexible container containing a solution are connected by a tube. The medicine container and the flexible container are communicated by the communication means provided, and the medicine and the solution are mixed aseptically. In addition, Japanese Patent Application Laid-Open No.
The capsule disclosed in Japanese Patent Application Publication No. JP-A-2003-175572 connects a capsule containing a medicine container to an opening of a dissolving solution container at a joint thereof, and interposes communication means provided with a communication order regulating means on the joint part side of the capsule. In, after the drug container is pierced by the communication means, the dissolution solution container is pierced and the two containers are communicated, so that the drug and the solution are aseptically mixed,
Japanese Unexamined Utility Model Publication No. 63-135,642 discloses a dissolving solution container in which a cylindrical support ring is provided at a seal portion at an opening of the dissolving solution container, and a double-ended needle is attached to the support ring so as to be vertically slidable. When the double-ended needle is slid downward, the lower needle pierces the seal at the mouth of the solution container.

[0004]

The conventional infusion container disclosed in Japanese Utility Model Laid-Open Publication No. 63-135842 is an infusion container with communication means. Includes those integrated as they are. Further, those disclosed in JP-T-61-501129 and JP-A-2-1277 are
In each case, a vial, which is a general distribution form of a dry drug, is directly taken in and integrated, and in that sense, versatility is high. However, JP-T-61-501129
The infusion container disclosed in the above publication has a large number of parts and requires time and effort to open the passage by folding the breakable member by hand. It has the disadvantage that it takes time.
The infusion container disclosed in JP-A-1277 is considerably improved as compared with the infusion container disclosed in JP-T-61-501129 in terms of prevention of contamination of the internal medicine and simplification of communication between the medicine container and the solution container. However, it has the drawback that the parts such as the communication order control means are complicated and the number of parts is large as a whole.
The infusion container disclosed in JP-A-3-135624 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 remove the solution. It is necessary to connect an infusion set or the like to the seal at the mouth of the dissolving solution container after inverting the container and extracting the double-ended needle, which requires time and effort to operate, and may cause leakage of the mixed chemical when the double-ended needle is removed. There is
It has disadvantages such as.

The present invention has been made in view of the above-mentioned circumstances, and is an improvement of a conventional medicine container, which is easy to operate, requires less labor, has a small number of parts, and is aseptically mixed with a solution. It is an object of the present invention to provide a medicine container set provided with a communication means capable of performing the communication.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a medicine comprising a bottomed cylindrical container body having a reduced diameter opening and a rubber stopper for closing the opening of the container body. An assembly comprising a container, communication means provided at the mouth of the harmful drug container, and a cover member for protecting the communication means, wherein the communication means is attached to the body and extends vertically along the outer wall thereof. A supporting portion slidable airtightly, a locking portion having a diameter that is continuous with the supporting portion and having an engaging projection that engages with the outer wall of the mouth at a lower portion thereof, and a partition wall above the locking portion. A medicine container set including communication means constituted by a double-ended needle fixed through the communication means and configured so that the medicine container is communicated with the outside by the communication means when the communication means is moved downward is adopted. .

[0007]

According to the above construction, when the cover member is removed from the communicating means, and the rubber stopper at the mouth of the solution container is put on the upper puncture needle of the double-ended needle and pushed down, the communicating means slides downward. Then, the rubber stopper at the mouth of the medicine container is pierced by the lower puncture needle of the double-ended needle, and the inside of the medicine container communicates with the chemical solution passage of the double-ended needle. On the other hand, the rubber stopper at the mouth of the dissolving solution container is pierced by the upper puncture needle of the double-ended needle, and the inside of the dissolving solution container communicates with the drug solution passage of the double-ended needle. Communicate with container.

A communication means 2 is provided at the mouth 12 of the medicine container 1 having the above-described structure. The communication means 2 comprises a support portion 21, an engagement portion 22, and a double-ended needle 24. Support part 21
Is formed in a cylindrical shape having an inner diameter substantially equal to the outer shape of the body 14 of the medicine container 1, and has an open end attached to the outer wall of the body 14 of the medicine container 1 so as to be airtight and slidable vertically. The locking portion 22 is reduced in diameter and continuous with the support portion 21, and is formed in a cylindrical shape whose inner diameter is slightly larger than the outer diameter of the mouth portion 12 of the medicine container 1. The lower part of the mouth 12
An engagement projection 221 is provided to engage with the caulking member 15 and restrict the inadvertent downward movement of the communication means 2, and a double-ended needle 24 is fixed to the upper portion thereof via a partition wall 23. The double-ended needle 24 usually has one or two vertically extending drug solution passages 413, and is composed of an upper puncture needle 241 and a lower puncture needle 242 separated by a partition wall 23.

The communication means 2 is usually made of polypropylene or A
The cover member 3 is integrally formed of a synthetic resin such as a BS resin or a polycarbonate, and has a cover member 3 attached to an upper end thereof by means of a screwing or the like for protection from contamination. The material for forming the cover member 5 is not particularly limited, but polyethylene, polypropylene, polyester, or the like is preferable. An O-ring 25 seals between the body 14 of the medicine container 1 and the support 21 of the communication means 2.
26 is a packing for sealing between the upper end of the locking portion 22 of the communication means 2 and the cover member 3.
