Abstract

See full text

A syringe device and injector system including a vent for relieving a vacuum within a syringe is provided. Embodiments provide a syringe device including a reservoir having a sidewall. The reservoir includes a dispensing distal end a proximal end. The syringe device also includes a piston in movable sealing engagement with the sidewall. Furthermore, the sidewall defines a vent extending from the proximal end of the reservoir. The vent is configured to interrupt the sealing engagement between the piston and the sidewall so as to allow a gas to enter the reservoir through the proximal aperture and past the piston member as the piston member is moved from the distal end to the proximal end of the tubular aperture.
