摘要

The invention relates to a one-way injector with a housing, a folding - zumidnest temporarily - the injectors, which can be filled, first cylinder - piston - unit and a means of this advance detachable container adapter, wherein the container adaptor, a likewise which can be filled at least temporarily second cylinders - piston - unit carries. In the first cylinder - piston - unit is mounted a solvent. In the second, there is a lyophilized drug. Immediately before use of the one-time injection port, the solvent in the second cylinder - piston - unit to be conveyed arneistoff. A solution forms there. This solution is introduced into the first cylinder - piston - unit to be recirculated in order then to be able to be administered.With the present invention, a one-way injector have been developed, which a fluid and an active substance is mounted in a sterile manner separately in each case and a space available, in which the active compound for the application or dissolved in the liquid is mixed with the liquid.
