Description

Medical container

The present invention relates to a medical container, and more specifically, a powder preparation, a freeze-dried preparation, a solid preparation and other dry drugs, and a solution that dissolves the dry drug is stored and used separately. The present invention relates to a medical container used when a dry medicine and a solution are mixed in an infusion container immediately before being supplied as a liquid medicine.

In medical institutions such as hospitals, dry drugs contained in drug containers such as vials are dissolved in distilled water, saline, glucose solution, dissolved solution, and other dissolved solutions to adjust the liquid drug, and this is used for infusion injections. Liquid chemicals are used.

In order to be able to easily adjust such liquid chemicals, a drug container containing a dry drug was connected in series to an infusion container containing a dissolved solution, and the inside of these two containers communicated with each other during use. Medical containers are disclosed in JP-A-5-337163 (Patent Document 1) and JP-A-10-165479 (Patent Document 2).

The medical container disclosed in each patent document is commonly called a “half kit”, and a communicating member equipped with a double-ended needle having a hollow conduit is attached to an infusion container storing a solution. In use, by pushing the drug container toward the puncture needle on one side of the double-ended needle, the communicating member moves to the infusion container side, the puncture needle on one side of the double-ended needle is pierced by the drug container, and the other side of the double-ended needle The puncture needle is pierced through the infusion container.

As a result, the inside of the infusion container and the inside of the drug container are simultaneously in communication with each other by the double-ended needle. Thereby, it becomes possible to melt | dissolve a dry chemical | medical agent in the solution of an infusion container by an easy operation | work.

JP-A-5-337163 JP-A-10-165479

However, in the medical containers disclosed in each of the above patent documents, the puncture needle is disengaged from the center of the elastic closure membrane when the double-needle puncture needle is inserted into the elastic closure membrane (rubber plug) provided in the drug container. May be pierced to a different location. In some cases, the puncture needle is not pierced perpendicularly to the elastic closure membrane, and the puncture needle is pierced in a state inclined with respect to the elastic closure membrane (so-called “oblique puncture”).

As described above, when the puncture state of the double-ended needle puncture needle into the drug container is not normal, a gap is formed between the elastic closure membrane of the drug container and the puncture needle, so that the solution in the infusion container is externally exposed. May leak. A case where a plurality of medicine containers are connected and a plurality of medicines are dissolved in the solution to adjust the liquid medicine is also conceivable.

When moved to the position, the connection between the drug container holding member 310 and the communication member 350 is released by the holding structure described above.

Furthermore, the communication member 350 is held on the inner surface of the cylindrical portion 301a, and only the drug container holding member 310 holding the drug container 500 moves to the open portion 301b side, and the first puncture needle 356a is moved to the elastic closure film 510s. The piercing will be cancelled. Thereafter, similarly to FIG. 10, the medicine container 500 is detached from the medicine container holding member 310.

As described above, also in the present embodiment, the drug container 500 containing different dry drugs is mounted on the drug container holding member 310 again, and the different dry drugs and the solution S are mixed in an aseptic condition to obtain a liquid drug. It is also possible to supply as.

Furthermore, as shown in FIG. 16, since the piercing of the second puncture needle 356b to the passage closing film 301s is also released, the liquid medicine does not leak from the infusion container 100. Thereby, it becomes possible to carry a medical container to a hospital room etc. after adjustment of a solution and a dry medicine.

As mentioned above, although each embodiment based on this invention was described, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
