LOW INSERTION FORCE SYRINGE STOPPERS, ASSEMBLIES, AND ASSOCIATED METHODS

Plunger rod head and syringe stopper pocket designs that facilitate reduced axial insertion forces while coupling plunger rods to stoppers (e.g., for use in pre-filled syringe assemblies). Desirable axial insertion forces may be lower than the associated break loose forces between the stoppers and t...

Zusammenfassung:Plunger rod head and syringe stopper pocket designs that facilitate reduced axial insertion forces while coupling plunger rods to stoppers (e.g., for use in pre-filled syringe assemblies). Desirable axial insertion forces may be lower than the associated break loose forces between the stoppers and their associated syringe barrels, with designs still ensuring the rod head and syringe stopper are coupled and require a substantial, non-zero separation force to de-couple the components.
