Abstract
A syringe inspection device and method for determining the position of a cannula in a cannula shield attached to a syringe. An electromagnetic radiation emitter is configured to emit electromagnetic radiation having a propagation axis. An electromagnetic radiation detector has an inspection window defined by a beam restrictor. A mount is configured to releasably retain the syringe between the emitter and the detector such that a longitudinal axis of the syringe is substantially coincident with the propagation axis. An image analyzer is operatively coupled to the detector. The image analyzer is configured to produce a syringe rejection signal when the cannula is irradiated and an electromagnetic image in the inspection window has two or less distinctly separate objects based on a contiguity of pixels having substantially like-valued intensity.
