Abstract
The disclosed embodiments provide for a syringe mount for a medical fluid power injector. The syringe mount is designed to hold a syringe so that a drive of the medical fluid power injector can move a plunger of the syringe to expel medical fluid from the syringe. The syringe mount comprises a first syringe clamp comprising a first arcuate surface, and a second syringe clamp comprising a second arcuate surface, wherein the first and second syringe clamps are in opposing relation to one another such that the first arcuate surface faces the second arcuate surface, and wherein the first and second syringe clamps are adapted to translate in opposite linear directions toward and away from one another to engage and disengage a syringe located therebetween.
Claims24
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 housing and comprising:
- a first syringe clamp comprising a first arcuate surface;
- a second syringe clamp comprising a second arcuate surface;
- and
- a lever configured to actuate each of the first and second syringe clamps between a syringe-engaging, closed position and a syringe-disengaging, open position, wherein the lever is movable relative to each of the first and second syringe clamps between first and second lever positions,
- wherein the first and second syringe clamps are in opposing relation to one another such that the first arcuate surface faces the second arcuate surface, wherein the first and second syringe clamps translate in opposite linear directions toward and away from one another to engage and disengage a syringe located therebetween, and wherein moving the lever into the first lever position linearly moves each of the first and second syringe clamps to the syringe-disengaging, open position, and wherein moving the lever into the second lever position linearly moves each of the first and second syringe clamps to the syringe-engaging, closed position.
A method of using a powered contrast media injector, the method comprising:
- executing a first placing step comprising placing a syringe mounting system in an open condition, wherein the syringe mounting system comprises first and second syringe clamps, and wherein the first placing step comprises linearly moving the first and second syringe clamps away from each other;
- disposing a rearward portion of a syringe between the first and second syringe clamps, wherein each of the first and second syringe clamps comprises an arcuate surface, and wherein the disposing step is executed after the first placing step;
- and
- executing a second placing step comprising placing the syringe mounting system in a closed condition, wherein the second placing step is executed after the disposing step and without moving the syringe relative to the injector, and wherein said second placing step comprises linearly moving the first and second syringe clamps toward one another at least until each of the arcuate surfaces contacts the rearward portion of the syringe.
A method of using a powered contrast media injector, the method comprising:
- disposing a rearward portion of a syringe between first and second syringe clamps of the injector;
- executing a first translating step comprising translating each of the first and second syringe clamps into a syringe-engaging, closed position, wherein the first translating step consists essentially of moving a lever into a first position and relative to each of the first and second syringe clamps;
- executing a second translating step comprising translating each of the first and second syringe clamps into a syringe-disengaging, open position, wherein the second translating step consists essentially of moving the lever into a second position and relative to each of the first and second syringe clamps;
- and
- moving the syringe out from between the first and second syringe clamps after the second translating step.
