<p>A device to be used in the filling and sealing of injection cartridges of the dual-chamber type comprises a cylindrical sleeve (7) which is arranged slidably around said cartridge, and a stopper (11) which is directed rearward and is coaxial with the sleeve and the cartridge. The sleeve (7) with the stopper (11) is arranged around the cartridge before the contents of the cartridge is subjected to a freeze-drying process, such that a vapor connection (16) exists between the interior of the cartridge and the exterior of the sleeve. After completed freeze-drying, the sleeve (7) and the stopper (11) are displaced rearwards, such that the stopper (11) enters the neck (2) of the cartridge and seals it. This is carried out before the cartridge has come into contact with atmospheric air. At its rear end, the sleeve (7) may be provided with an attachment (17) for a device for preparing and administering injections.</p> |
