Abstract
A syringe interface for attaching syringes to a drive mechanism which includes a drive member to impart motion to a syringe plunger includes a plurality of syringe mount apertures having different dimensions to attach each of a plurality of syringes to the syringe interface. Each of the syringes for attachment to the syringe interface includes at least one mounting flange, and each of the plurality of syringes has a different mounting flange dimension. Each of the plurality of syringe mount apertures is in general alignment with an axis of the drive member. A syringe drive mechanism includes a syringe interface as described above. The syringe drive mechanism can further include a sensing system to sense which size of the plurality of syringes is mounted on the syringe interface. The syringe drive mechanism can also include a processor and a memory which are in operative communication with the drive member. The memory includes a control program stored therein. The processor is in communication with the sensing system so that the control program controls the drive member according to the syringe sensed to be attached to the syringe interface. A powered injector includes a drive membe…
