Patent ID: 7192417

Claim:
A syringe interface for attaching a plurality syringes having different barrel diameters to a drive mechanism including a drive member, each of the syringes including at least one mounting flange, the at least one mounting flange of syringes of different barrel diameters extending radially outward to different extents, the syringe interface including a plurality of syringe mount apertures having different dimensions to attach each of the plurality of syringes to the syringe interface, each syringe mount aperture being positioned at a different axial position on the syringe interface such that the syringe mount apertures having a larger diameter are positioned forward of the syringe mount apertures having a smaller diameter each of the plurality of syringe mount apertures having an axis in general alignment with an axis of the drive member, each of the syringe mount apertures of the syringe interface comprising at least one retaining flange, the retaining flange of each syringe mount aperture projecting radially inward to a different radial position to cooperate with the at least one mounting flange of one of the syringes, each of the retaining flanges of each of the syringe mount apertures being in general alignment about the circumference of the syringe.
