Abstract
A method of automatically producing a plurality of prefilled, sterile delivery devices with a desired quantity of fluid. The sterile delivery devices each include a hollow barrel with a dispensing nozzle at one end and an open opposite end. A piston plunger is positioned within the open end and is slidable in sealing engagement with the barrel to retain a fluid therein. A tip is secured to the dispensing nozzle. A plurality of the sterile delivery devices are automatically fed along a predetermined path. Tips are then removed from the dispensing nozzles of the sterile delivery devices. The hollow barrels of the sterile delivery devices are then filled through the dispensing nozzles with a desired is quantity of fluid. The dispensing nozzles of the sterile delivery devices are then closed and sealed after the filling step to provide sealed sterile delivery devices with sterile fluid contents.
