Abstract
A power injector (110) is disclosed that operates a drive train (116) in a single, common configuration to operate each of a first syringe (132) and a second syringe (152). That is, no changes need to be made to the drive train (116) to change the discharge from the first syringe (132) to the second syringe (152), or vice versa. In one embodiment, the first plunger (140) of the first syringe (132) is maintained in a stationary position, while its corresponding first syringe barrel or housing (134) is moved, to provide a discharge from the first syringe (132). Conversely for the noted embodiment, the second plunger (160) of the second syringe (152) is moved, while its corresponding second syringe barrel or housing (154) is maintained in a stationary position.
