Abstract

Injection syringe, partic. for use with a pharmaceutical prod., contains an active prod. and a liq. solvent which should not be mixed until the moment of injection. The syringe has a cylindrical body which is divided by a first, elastic, sliding stopper into an upper chamber contg. the active prod. and a lower chamber contg. the liq. solvent. The internal wall of the upper chamber is provided with four longitudinal grooves. In the storage posn. the stopper is located below these grooves. The upper chamber opens into the outlet nozzle which is protected by a safety cap. The lower chamber is closed by the second, elastic sliding stopper to which the piston can be screwed. The piston is pushed inside the cylindrical body; the pressure, transmitted by the solvent, causes the first stopper to slide until it comes opposite the grooves; the liq. passes through the grooves and penetrates into the upper chamber where it dissolves the active prod. With all the liq. solvent now in the upper chamber, the mixt. is ready to be injected. The pharmaceutical prods. are stored separately in the syringe and are only mixed at the last moment before the injection is effected.
