  • Patent number: 5947951
    Abstract: A method and apparatus for automatically transferring a predetermined quantity of a sterile liquid to a vial containing a dry medicament for hydrating the medicament and then transferring the hydrated medicament to a container. To hydrate the medicament, a needle is positioned through a vial septum of the vial and an artificial sensor senses when the needle has been positioned through the vial septum and actuates a pump to transfer a predetermined quantity of sterile liquid into the vial. The needle is then removed from the vial septum and the vial is shaken to mix the liquid and medicament. To transfer the hydrated medicament to a container, another needle is positioned through the vial septum. An artificial sensor senses when the needle has been positioned through the vial septum and actuates the pump to transfer the hydrated medicament to the container.

  • Patent number: 5884457
    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.
