Abstract
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.
