Abstract
A cartridge for radiopharmaceutical packaging includes a low UV-absorbing plastic barrel, closed at one end by a cap and at the other by a piston. A shoulder cooperates with the barrel in a double-level snap-on system with a cavity cooperating with an injection fitting sleeve to make a seal. At a first end the cap has a peel-off porous liner covering the cavity. Radial fins protrude inside the cavity, for screwing the injection fitting and second radial fins protrude outside of the cap to fix to a cartridge protection shield. A second end minimizes a shadow area of UV flash lamp sterilization and ensures clearance for inserting an injection spike. The second end has a reduced wall thickness pierced by the spike during set up for dispensing of the pharmaceutical. An external cylindrical zone at the second end ensures leak tightness between the cap and the barrel.
