Abstract:
1. A powerhead of a contrast media injector system, the powerhead comprising: a housing comprising first and second sides; a first syringe ram movable relative to said housing, wherein said first side comprises said first syringe ram, and wherein said first syringe ram is configured to engage a plunger of a first syringe when installed on said first side; a second syringe ram movable relative to said housing, wherein said second side comprises said second syringe ram, and wherein said second syringe ram is configured to engage a plunger of a second syringe when installed on said second side; a drive mechanism within said housing, said drive mechanism configured to move said first syringe ram and said second syringe ram; a syringe accessory for association with a syringe when installed on said housing, said syringe accessory comprising a first electrical component and a syringe accessory connector for electrically connecting said first electrical component to said powerhead; and a microprocessor, said microprocessor comprising circuitry for controlling said drive mechanism in a programmed manner to effect an injection into a patient, said circuitry comprising a first connector and a second connector, said syringe accessory connector being electrically connectable to one of said first and second connectors at a given time, and said circuitry comprising circuitry that distinguishes whether said syringe accessory is installed on said first side or said second side of said housing when said syringe accessory is installed in each of first and second configurations, said first configuration being when said syringe accessory connector is electrically connected to said first connector and said second configuration being when said syringe accessory connector is electrically connected to said second connector, wherein when said syringe accessory is installed in said first configuration, said circuitry determines whether said syringe is installed on said first side or said second side of said housing and when said syringe accessory is installed in said second configuration, said circuitry determines whether said syringe is installed on said first side or said second side of said housing such that said microprocessor may proceed appropriately with controlling said injection.
