Abstract:
1. A front-loading, contrast media injector comprising: an injector housing having an opening defined therein; a drive ram, at least a portion of which is movable into and out of the injector housing along a longitudinal reference axis of the drive ram through the opening in the injector housing; and a syringe mount coupled to the injector housing and comprising a plurality of retainer components, wherein the plurality of retainer components collectively define a syringe-receiving aperture that is aligned with the opening in the injector housing, wherein each the plurality of retainer components are disposed about an exterior of a syringe and are in position to restrain movement of a syringe away from the injector housing when the syringe is installed on the contrast media injector and as the drive ram is advanced in the direction of the syringe, wherein each of the retainer components comprises a sloped surface that defines a perimeter portion of the syringe-receiving aperture, wherein the sloped surface of each of the retainer components projects in a direction of the longitudinal reference axis and projects toward the exterior of the syringe when installed on the contrast media injector using the syringe mount, wherein the sloped surface of each of the retainer components slopes toward the longitudinal reference axis of the drive ram progressing along the longitudinal reference axis in the direction of the injector housing, wherein each of the retainer components translates linearly toward the longitudinal reference axis, wherein each of the retainer components translates linearly away from the longitudinal reference axis, wherein each of the retainer components is biased toward the longitudinal reference axis, wherein the plurality of retainer components comprises first and second retainer components, wherein the first and second retainer components each translate linearly toward the longitudinal reference axis to both reduce a spacing between the first and second retainer components and to reduce a size of the syringe-receiving aperture, wherein the first and second retainer components each translate linearly away from the longitudinal reference axis to both increase the spacing between the first and second retainer components and to increase the size of the syringe-receiving aperture, and wherein the size of the syringe-receiving aperture is taken perpendicularly to the longitudinal reference axis.
