MULTICYLINDER TYPE CONNECTING MECHANISM FOR DRUG CONTAINER AND DISSOLVING LIQUID CONTAINER

摘要

PURPOSE:To develop a connecting mechanism which can easily prepare diversified drug solns. from drugs and dissolving liquid in a nearly use stage. CONSTITUTION:A connecting outside cylinder 7 fitted to the outer side of a connecting inside cylinder 3 rising from the top plate of a crown cap 2 to an upstream side is engaged and mounted near the outer edge of a crown cap 1 and an injection cylinder 5 housing the dissolving liquid is mounted to the inner side of the connecting inside cylinder 3 and is engaged and mounted to and with the outside cylinder 7. A plug 6 in common use as a downstream side piston is mounted into an inside pipe 51 of the double pipe parts at the downstream end of the injection cylinder 5 and the upstream side part of a puncture needle member is internally fitted to the downstream side thereof. This puncture needle member is fitted onto a downstream end pointed puncture needle 41 and an upstream side part and is formed with a sleeve cylinder 42 fitted and mounted between the inside pipe 51 and the outside pipe 52 and further an expandable leg part 43 extending from the outer side thereof to the upstream side and fitted onto the outside pipe 52. A plug 8 in common use as an upstream side piston is fitted into the upstream end of the injection 5. Then, the liquid drugs of the combination most approximate to a request are rapidly and hygienically prepd. from the drugs and dissolving liquid of the available limited kinds and volume. The restrictions by commercially marketed kits are relieved.
