Patent ID: 8439876

Claim:
An injector system comprising: at least one syringe comprising at least a first indicator positioned on the at least one syringe at a predetermined position, the predetermined position of the at least a first indicator being associated with information about a syringe configuration; and a powered injector comprising a drive member and at least a first contact member movably disposed in the powered injector, the at least a first contact member is positioned to come into contact with the at least a first indicator when the at least one syringe is attached to the powered injector such that a position of the at least a first contact member is determined by the predetermined position of the at least a first indicator, an amount of change in the position of the at least a first contact member as a result of contact with the at least a first indicator being associated with the syringe configuration, wherein the powered injector further comprises a plurality of sensors and at least a first shutter mechanism in operative connection with the at least a first contact member, each of the plurality of sensors having an on state and an off state, the at least a first shutter mechanism comprising at least one cooperating member to cooperate with at least one of the plurality of sensors to place the at least one of the plurality of sensors in the on state or the off state, the on state or the off state of each of the plurality of sensors providing a digital code corresponding to information on the syringe configuration.
