摘要： Barrel adapters for safety syringes include a barrel and a plunger assembly adapted to move within the barrel, a barrel tip adapted to be sealingly engaged with a distal end of the barrel and a needle retraction mechanism barrel having a needle subassembly and an actuator subassembly. The needle subassembly includes a needle, and a needle-over-mold (NOM) through which the needle extends. The needle subassembly is disposed at least partially within the barrel tip, and adapted to move from an injection position in which the needle extends from a distal end of the barrel tip to a retracted position in which the needle is disposed within at least one of the barrel tip or the barrel. The actuator subassembly includes a needle seal, a push-bar, and an actuator surface. The needle retraction mechanism barrel includes a biasing member and an actuable locking arrangement. A syringe includes such barrel adapters.

摘要： A user-initiated fluid pathway connection includes: a connection hub, a piercing member, a sterile sleeve, and a drug container having a cap, a pierceable seal, a barrel, and a plunger seal, wherein the piercing member is initially retained within the sterile sleeve between the connection hub and the pierceable seal of the drug container. The connection hub may include an internal aperture within the connection hub which functions as a flow restrictor and wherein a piercing member is connected to one end of the internal aperture and a fluid conduit is connected to another end of the internal aperture. A drug delivery pump with integrated sterility maintenance features includes a housing, upon which an activation mechanism, an insertion mechanism, a fluid pathway connection as described above, a power and control system, and a drive mechanism connected to a drug container are mounted. Methods of assembly and operation are also provided.
