Abstract: A method of preparing a prefilled syringe (1), comprises (i) obtaining a syringe barrel (11) having an open end (111) and a tip (112) with an orifice (113) essentially opposite to the open end (111), and a needle adaptor cap (12) assembled on the tip (112) of the syringe barrel, wherein the needle adaptor cap (12) has a rubber element (121) tightly sealing the orifice (113) of the tip (112) of the syringe barrel (11) and the syringe barrel (11) together with the needle adaptor cap (12) assembled on the tip (112) of the syringe barrel (11) is sterilized by a first sterilizing comprising a main step of exposing the syringe barrel (11) together with the needle adaptor cap (12) assembled on the tip (112) of the syringe barrel (11) to ethylene oxide for about 5 hours to about 60 hours at a relative humidity of about 40% to about 100% and at a temperature of about 30° C. to about 60° C.

Abstract: A method of preparing a prefilled syringe is disclosed that includes obtaining a syringe barrel and a needle adaptor cap assembled on the tip of the syringe barrel, wherein the needle adaptor cap has a rubber element tightly sealing the orifice of the tip of the syringe barrel and the syringe barrel together with the needle adaptor cap assembled on the tip of the syringe barrel is sterilized by a first sterilizing. Filling a drug substance into an interior of the syringe barrel and sealing the interior of the syringe barrel. Packaging the syringe barrel with a rubber stopper sealing the interior thereof and the needle adaptor cap assembled on the tip of the syringe barrel. Providing a second external surface sterilizing of the packaged syringe barrel with the rubber stopper sealing the interior thereof and the needle adaptor cap assembled on the tip of the syringe barrel.

Abstract: A reduced profile syringe assembly is provided that includes an overall profile that is substantially similar to a profile of a syringe barrel. The syringe assembly includes a plunger rod that is significantly disposed within the syringe barrel when filled for use, with the plunger rod adapted to be retracted from the syringe barrel during dispensing of contents of the syringe barrel.

Abstract: A syringe pack with a prefilled syringe (1) and a packaging (2) comprises: a barrel part (11) with an orifice (113) at a proximal end and a flange portion (112) at a distal end; a plunger part (13) extending through the distal end of the barrel part (11) into the barrel part (11); a stopper (12) adjacent to a proximal end of the plunger part (13) and arranged inside the barrel part (11) such that a dosage chamber (111) is formed inside the barrel part (11); and a drug substance arranged inside the dosage chamber (111), wherein the prefilled syringe (1) is arranged in the packaging (2) and the packaging (2) is configured to allow external sterilization of the prefilled syringe (1) arranged in the packaging (2).

Abstract: An automatic mixing device, an actuating device having integrated plunger and configured to be removably mounted to the automatic mixing device, and a retractable syringe having the automatic mixing device are provided. The actuating device has an initially compressed spring and a trigger member that is rotatable to initiate spring decompression to drive depression of a mixing plunger seal of the automatic mixing device. Another seal located in an outer chamber of the mixing device is capable of axial movement upon depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in an inner barrel to a second position intermediate the apertures and vents in an outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in an inner chamber of the inner barrel. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.

Abstract: The invention provides a syringe assembly comprising a syringe barrel having an inside surface defining a chamber, an open proximal end, and a distal end having an opening therethrough. An elongated plunger rod extends between a first end and a second end, with a cap or guard disposed on the first end of the plunger rod. A plunger head extends within the chamber of the syringe barrel, and is adapted for slidable movement within the syringe barrel between the proximal end and the distal end, with the second end of the plunger rod connected with the plunger head through a pivotable connection. The plunger rod is adapted to pivot with respect to the plunger head between a first position in which the guard is adjacent the distal end of the syringe barrel and a second position in which the plunger rod is in general axial alignment with the syringe barrel, and is further adapted for axial movement so as to cause sliding movement of the plunger head through the syringe barrel to expel contents thereof.
