INJECTOR DEVICE, METHOD, AND COMPUTER PROGRAM PRODUCT FOR DETECTING A VACUUM WITHIN A SYRINGE
First Claim
1. An injector system adapted to be operably engaged with a syringe device comprising a reservoir including a dispensing distal end defining a dispensing aperture and a proximal end defining a proximal aperture, the syringe device further comprising a piston member movably disposed in the reservoir and configured to be movable between the distal end and the proximal end, the piston member being in movable sealing engagement with a reservoir sidewall, the injector system comprising:
- an actuator device configured to be selectively operably engaged with the piston member for extending the piston member toward the distal end and retracting the piston member toward the proximal end; and
a controller device in communication with the actuator device, the controller device being configured to detect an output generated by the actuator device when retracting the piston member, the output being associated with a pressure within the reservoir, the controller device being further configured to determine, via the detected output, when the pressure comprises a selected negative pressure and to provide an indicia thereof to a user or a signal thereof to the actuator device, in response to the determined selected negative pressure.

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.
