摘要:
A method to extract out of water, concentrate and reformulate [18F] fluorides includes passing a dilute aqueous [18F] fluoride solution entering by an inlet (1) in a cavity (6) embodying an electrochemical cell with at least two electrodes (3, 4, 5), flowing in the cavity (6) and coming out of the cavity (6) by an outlet (2), an external voltage being applied to the electrodes. One electrode (4) is used as an extraction electrode, another one (3) is used for polarizing the solution, and configured so that at least the extraction electrode (4), either used as a cathode or as an anode, is in contact with and polarizes a large specific surface area conducting material (7), contained in the cavity (6). The extracted ions are released from the surface of the large specific surface area conducting material (7) by turning off the applied external voltage. During its passage in the cavity (6), the dilute aqueous [18F] fluoride solution entirely crosses and internally soaks the large specific surface area conducting material (7).

摘要:
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.

摘要:
An improved cartridge for the packaging of a pharmaceutical, and preferably a radiopharmaceutical, comprising a low UV-absorbing plastic barrel, closed at one end by a cap and at the other end by a piston. Said cap is provided at least partly with: a shoulder cooperating with the barrel in a double-level snap-on system; a cavity to cooperate with an elastomeric protection sleeve of an injection means fitting, to make a seal, said cap being terminated at a first end by a peel-off porous liner covering said cavity; a first plurality of radial fins protruding inside said cavity, for screwing the injection means fitting and with a second plurality of radial fins protruding on the outside of the cap to ensure fixation of the cap into a cartridge protection shield; a second end opposite to the first end, shaped so that to minimize a shadow area in the case of UV flash lamp sterilization and to ensure sufficient clearance for inserting a spike of the injection means, said second end having a reduced wall thickness for acting as a septum intended to be pierced by said spike at the time of setting up for dispensing the pharmaceutical to a patient; an external cylindrical zone at this second end to ensure leak tightness between the cap and the barrel.
