  • Patent number: 8523807
    Abstract: A transfer and mixing device which utilizes a by-pass cartridge and a syringe. After mixing the dry component and the diluent in the by-pass cartridge, the mixture can be passed to a syringe which includes a syringe plunger having a fluid passageway therein with a hydrophobic membrane covering the passageway. The mixture can be transferred back and forth between the by-pass cartridge and the syringe through a small bore to achieve mixing, particularly in the case of microspheres held in suspension.

  • Publication number: 20050113763
    Abstract: The present invention provides for an assembly for filling and capping a barrel of a pre-filled syringe. The assembly includes a syringe body having a neck end, a rimmed end, and a side wall extending between the neck end and rimmed end. The body has an outer surface and an inner surface. The assembly includes a piston having an upper surface, a lower surface, and a side surface extending between the upper and lower surfaces. The inner surface of the body and the side surface of the piston is in contact to form a liquid impermeable seal. The assembly further includes a stabilization member that at least partially surrounds and contacts the outer surface of the body. The stabilization member is positioned proximate the rimmed end of the body to provide additional mass thereto in an amount sufficient to permit the assembly to be conveyed freestanding in a longitudinally upright position on the stabilization member through an apparatus for filling and capping pharmaceutical vials.

  • Patent number: 6802828
    Abstract: A system is provided which permits syringe barrels of prefilled disposable syringes to be filled and capped on standard vial filling equipment, and which permits the syringe body and piston comprising the barrel to be simultaneously sterilized by a sterilizing gas. The system provides means for stabilizing syringe barrels so they can be conveyed upright on their bases without tipping through vial filling and capping equipment. Preferably, the stabilizing means comprises a cylindrical sleeve into which the lower end of the syringe body is inserted, thereby stably supporting it against tipping. The system also provides means by which the piston is retained in close proximity to the lower end of the syringe body, but slightly separated therefrom to permit access to all surfaces of the piston by a sterilizing gas.

  • Patent number: 6638244
    Abstract: A system is provided for providing syringes filled with pharmaceuticals whose components must be stored separately, using a liquid such as water in a pharmaceutical vial, an active ingredient in a protosyringe such as a bottomless vial or a cartridge, and a combiner assembly which enables the content of the pharmaceutical vial to be transferred into the protosyringe and converts it into a ready-to-use syringe on activation. The combined assembly includes a tubular body having recesses at opposite ends for receiving capped ends of the vial and the protosyringe, and a hub and needle assembly between penetrable sheaths or shields which acts on activation of the assembly to enable the transfer and conversion referred to above. Components of the system may also be used to convert protosyringes and pharmaceutical vials containing pharmaceuticals into delivery systems.

  • Patent number: 5137511
    Abstract: A prefilled syringe for one or two component medicaments is based upon the use of a vial containing a medicament or one component of a medicament, the vial having an open bottom closed by a piston. When a flexible extension of the piston is coupled with a tubular plunger, and an adaptor cap having an internal needle and an external connection for a needle is placed over a cap of the vial, the latter is converted into a prefilled syringe. The piston may have an axial passage closed by a resealable septum, so that a separate diluent stored in a flexible capsule may be introduced into the vial through the piston by a double ended needle mounted on a further cap applied to the capsule, the further cap being coupled within the tubular interior of the plunger so that the double ended needle penetrates the septum in the piston. The capsule is pushed forward onto the double ended needle when its contents are to be expelled into the vial. The capsule and its cap are then removed and discarded.

  • Patent number: 4861335
    Abstract: A syringe provides for the isolated storage of two components of a medicament until immediately prior to use of the syringe. One liquid component is stored in a collapsible chamber of a sealed capsule within a hollow plunger stem of the syringe, and the other component beneath the head of the plunger. A double headed needle arrangement between the head and stem of the plunger is caused to penetrate the plunger head and the capsule when the syringe is to be used so that the plunger may be drawn back to exhaust the contents of the capsule chamber into admixture with the component stored beneath the head of the plunger. Communication through the double headed needle arrangement is then interrupted before the plunger is used to eject the syringe contents through an external needle fitted to the syringe.
