    Abstract: A method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.

    Abstract: A pressure sensor for use with a fluid delivery system having good sensitivity at low pressure, but also configured to remain in operating condition after being exposed to high pressures is disclosed herein. In one variation, the pressure sensor includes a fluid path set, a deformable element associated with the fluid path set and configured to deform in response to an external pressure, and a pressure transducer for monitoring deformation of the deformable element. In certain embodiments, the pressure sensor is configured to measure fluid pressure within the range of between about 0 mm Hg to about 300 mm Hg. However, the sensor pressure is also be configured to remain functional after being exposed to pressure in excess of about 60,000 mm Hg.

    Abstract: A pressure jacket includes a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis. The pressure jacket also includes at least one retaining member having at least one first lug protruding radially outward relative to an outer surface of the sidewall. The at least one first lug has at least one third surface tapered axially relative to the longitudinal axis of the barrel in a proximal direction. The at least one first lug is configured for engagement with a locking mechanism associated with a port on a fluid injector to releasably lock the pressure jacket with the fluid injector. At least a portion of the at least one third surface axially ejects the pressure jacket upon rotation of the pressure jacket about the longitudinal axis.

    Abstract: A fluid delivery system is provided and includes a power injector supporting a high pressure syringe. The fluid delivery system further includes a manifold and a low pressure hand-operated syringe. The manifold generally includes a plurality of fluid control valves in series fluid communication. A first fluid control valve of the plurality of fluid control valves has a first port, a second inlet port, and a third port. The third port of the first fluid control valve is in fluid connection with a first port of a second fluid control valve. The low pressure hand-operated syringe is in fluid connection with the first port of the first fluid control valve, and the high pressure syringe is in fluid connection with the second port of the first fluid control valve. The fluid control valves may be multi-position stopcock valves.

    Abstract: A syringe for a fluid delivery system includes a pressure jacket having a distal end, a proximal end, and a throughbore therebetween. The syringe further includes a rolling diaphragm having a proximal end with an end wall for engaging a plunger, a distal end received within the throughbore of the pressure jacket. The distal end of the rolling diaphragm has a nozzle and a sidewall extending between the proximal end and the distal end of the rolling diaphragm along a longitudinal axis. At least a portion of one of the sidewall and the end wall has non-uniform thickness. At least a portion of the sidewall is flexible and rolls upon itself when acted upon by the plunger such that an outer surface of the sidewall at a folding region is folded in a radially inward direction as the plunger is advanced from the proximal end to the distal end of the rolling diaphragm.
