Device for the administration of drugs, particularly two-component drugs

A device for the administration of drugs, comprising:

• a tubular housing having a double wall including an outer jacket and an inner jacket, said housing being open at one end and closed by an end wall at the opposite end;
• a container for holding a first liquid drug component, said container including a stopper in the form of a slidable piston, said stopper being couplable to the inner jacket of said housing and slidable into said container so as to apply a pressure to the first liquid drug component;
• a chamber formed within said inner jacket adjacent to the end wall of said housing, said chamber for holding a second drug component to be dissolved in said first liquid drug component;
• and
• a needle mounted within the inner jacket of said housing, said needle having one end opening into said chamber and the opposite pointed end extending toward the open end of said housing, said needle being positioned such that the pointed end perforates an axial bore through said stopper when said stopper is coupled to said inner jacket, so that said container communicates via said needle with said chamber, and when the slidable piston of said container slides into said container said first liquid drug component travels under pressure through said needle into said chamber and mixes with said second drug component.
