COUPLING SYSTEM FOR TRANSFERRING FLUIDS FROM A CARTRIDGE : BLUNT CANNULA IS JOINED TO A NEEDLE CANNULA

摘要

A coupling system for transferring fluids from a medicament-containing cartridge to an injection site comprises a fluid flow channel, a blunt cannula defining the distal end of the fluid flow channel, a needle cannula defining the proximal end of the fluid flow channel, and means for fixedly connecting the needle cannula to the blunt cannula.
