摘要： 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.

摘要： 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.

摘要： A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engagable with the piston regardless of a rotational orientation of the piston relative to the plunger.

摘要： A fluid path set includes a first fluid line having a proximal end fluidly connectable to a source of a first fluid and a second fluid line having a proximal end fluidly connectable to a source of a second fluid. A flow mixing device is in fluid communication with distal ends of the first and second fluid lines. The flow mixing device includes a housing, a first fluid port provided for receiving the first fluid, and a second fluid port for receiving the second fluid. A mixing chamber is disposed within the housing and is in fluid communication with the first and second fluid ports. A third fluid port in fluid communication with the mixing chamber for discharging a mixed solution of the first and second fluids. A turbulent flow inducing member is disposed within the mixing chamber for promoting turbulent mixing of the first and second fluids.

摘要： A pressure jacket for use with a fluid injector may have a pressure jacket body having a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a pressure jacket longitudinal axis. The pressure jacket may further have at least one resiliently deflectable retaining member having a first segment attached to the pressure jacket body and a second segment protruding from the first segment toward the distal end of the pressure jacket body and deflectable relative to the first segment. The pressure jacket may further have at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member may interact with a housing of the fluid injector when the pressure jacket is connected to the housing to deflect the at least one resiliently deflectable retaining member upon rotation of the pressure jacket.
