    摘要: An injector system, method and computer program product for detecting a vacuum within a syringe are provided. Various embodiments include an actuator device configured to be engaged with a piston member of a syringe for extending and retracting the piston member within the syringe. A controller device is also provided for detecting an output generated by the actuator device when retracting the piston member. The detected output may be associated with a pressure within the reservoir. The controller device determines, via the detected output, when the pressure comprises a selected negative pressure and provides an indicia of the negative pressure to a user and/or a signal to the actuator device.

    摘要: 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.
