Abstract
A system is provided for providing syringes filled with pharmaceuticals whose components must be stored separately, using a liquid such as water in a pharmaceutical vial, an active ingredient in a protosyringe such as a bottomless vial or a cartridge, and a combiner assembly which enables the content of the pharmaceutical vial to be transferred into the protosyringe and converts it into a ready-to-use syringe on activation. The combined assembly includes a tubular body having recesses at opposite ends for receiving capped ends of the vial and the protosyringe, and a hub and needle assembly between penetrable sheaths or shields which acts on activation of the assembly to enable the transfer and conversion referred to above. Components of the system may also be used to convert protosyringes and pharmaceutical vials containing pharmaceuticals into delivery systems.
