Abstract
A prefilled syringe for injecting medicament into a patient includes a barrel constructed of a polymeric material, a cannula and a hub. The barrel has a diameter, a longitudinal axis, a proximal end and a distal end. The cannula has a proximal end and a tip opposite the proximal end. The proximal end of the cannula is fixed to the distal end of the barrel. The cannula is positioned generally coaxially with the longitudinal axis. The hub is integrally formed with the distal end. The hub includes a rib section and a cap. The rib section has a generally cruciform cross-section taken along a rib plane. The rib plane is generally perpendicular to the longitudinal axis. The cap has a generally U-shaped cross-section taken along a longitudinal plane. The longitudinal plane is generally parallel to the longitudinal axis.
