DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to medicine containers which comprise a container having an antibiotic or like medicine hermetically accommodated therein and another container joined thereto and similarly containing a liquid for dissolving the medicine, such that when the medicine is to be administered to the patient as by drip infusion, the two component containers are caused to aseptically communicate with each other to mix the contents together into a solution.
BACKGROUND ART
Research has been conducted on various medicine containers of the type described, which include those having a double-ended needle. These containers have the advantage of being usable for medicines as contained in conventional vials and not permitting ingress of broken fragments of such as rubber closures used in the vial into the dissolving solution. Some of the containers of the same type already proposed have the structure disclosed in Unexamined Japanese Utility Model Publication SHO 63-135642 (see FIGS. 6 to 8 in particular) or in Unexamined Japanese Patent Publication HEI 2-1277. The medicine container of the former publication has the advantage of being simple in structure and disposable as divided into components, but still remains to be improved in construction for the ease of mixing procedure and has the likelihood of peel paper separating off, for example, during transport. The medicine container of the latter, although free of the problem of the former container, has the problem of being complex in structure, costly to make and not disposable as separated into components. Thus, the proposed containers have both merits and demerits.
DISCLOSURE OF THE INVENTION
The main object of the present invention is to provide a medicine container which is excellent in impact resistance and shakeproofness for transport and storage, usable through a facilitated mixing procedure for preparing a medicinal solution, simple in overall construction and disposable as separated into components after use.
Other features of the present invention will become apparent from the following description.
The present invention provides a medicine container characterized in that the container comprises: upper end thereof, seal portion of the dissolving liquid container so as to extend upward from the opening seal portion concentrically therewith, downward, the needle being usually held in an upper position above the opening seal portion and movable from the upper position to a lower position to pierce the seal portion for use, end thereof and usually held in a first joined position of shallow fit, the inner tube being movably from the first joined position to a second joined position of deep fit for use, inverted state in the inner tube with an opening seal portion of the vial directed downward, the vial being positioned above the needle in the upper position when the inner tube is in the first joined position and movable with the movement of the inner tube to a position where the opening seal portion of the vial is pierced by the needle in the lower position when the inner tube moves to the second joined position, inner tube for usually restraining the inner tube in the first joined position relative to the outer tube and releasing the inner tube from the restrained position for use, and tube for holding the joint hermetic.
The inner tube and the outer tube can be reliably held joined together as predetermined with good stability by the restraining mechanism provided on the joint between the inner tube and the outer tube while the medicine container of the invention is being transported. Furthermore, the medicine and the liquid packaged in the medicine container can be mixed together easily by forcing the inner tube into the outer tube. After a solution has been prepared by the mixing procedure, it is possible to separate the dissolving liquid container from the outer tube at the joint therebetween, to separate the inner tube from the outer tube by withdrawing the inner tube therefrom and, when required, to withdraw the double-end
