  • Publication number: 20230310681
    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.

  • Patent number: 11738106
    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.

  • Publication number: 20210052816
    Abstract: A prefilled syringe is disclosed that includes a barrel, a stopper displaceable within and defining a sealed chamber in an interior of the barrel, a liquid filled in the chamber of the barrel, and a plunger extending within the barrel. The stopper expels the liquid out of the barrel via an orifice when being forwarded towards the orifice by the plunger such that a volume of the chamber is reduced. The plunger includes a proximal portion, a distal portion and a rod portion extending between the proximal portion and the distal portion. The plunger is shaped to form a pathway between an opening of the barrel and a segment where the proximal portion of the plunger is neighboring the stopper such that a sterilizing agent can be provided through the opening of the barrel to the segment where the proximal portion of the plunger is neighboring the stopper.
