The fluid injection apparatus includes a syringe, an injector, and a pressure jacket. The syringe has a cylindrical body with an injection section at a distal end and a plurality of outward extending retaining flanges at a proximal end. The injector has an injector housing defining a central opening and an injector drive piston extendable through the central opening for imparting motive forces to a syringe plunger disposed within the syringe. The pressure jacket secures the syringe during an injection procedure. The pressure jacket has a wall defining a plurality of longitudinally extending grooves in an inner surface thereof configured to receive the retaining flanges of the syringe. The grooves cooperate with a plurality of transversely extending slots defined in the inner surface of the pressure jacket wall. The engagement of the retaining flanges in the slots via the grooves secures the syringe in the pressure jacket.

The fluid path set is intended for use in a fluid delivery system. The fluid path set includes a multi-patient use section adapted for connection to a syringe used in the fluid delivery system, and to a source of fluid, such as contrast media, to be loaded into the syringe. The fluid path set further includes a per-patient use section that is removably connected to the multi-patient use section. A connector removably connects the multi-patient use section and the per-patient use section. A drip chamber is provided between the source of fluid and the syringe, and includes a projection for determining a level of fluid in the drip chamber. The per-patient use section includes a pressure isolation mechanism. The pressure isolation mechanism includes a lumen, a pressure isolation port, and a valve member with a biasing portion that biases the valve member to a normally open position.

Methods for capacitance volume correction in fluid-containing expandable bodies and associated fluid pathways are disclosed. The methods may be applied in fluid delivery systems used to supply fluids to patients during radiographic imaging procedures, including angiography. The methods control delivery of fluid to a downstream process, including providing a fluid-delivery expandable body and a pressurizing element in fluid communication with the downstream process, pressurizing the expandable body by moving the pressurizing element in the expandable body to reduce volume therein, determining an over-travel distance for the pressurizing element, and ceasing movement of the pressurizing element after allowing the pressurizing element to over-travel the over-travel distance to compensate for expansion of the expandable body under pressure. The expandable body may be a syringe and the pressurizing element may be a plunger disposed within the syringe. Movement of the pressurizing element may be controlled by an algorithm associated with a computer.

The fluid delivery system includes a pressurizing device for delivering a pressurized injection fluid, a low pressure fluid delivery system, and a pressure isolation mechanism adapted for fluid communication with the pressurizing device and low pressure fluid delivery system. The pressure isolation mechanism includes a housing defining an inlet port, an isolation port, and an internal cavity. The housing defines a seal seat in the internal cavity between the inlet port and isolation port. A valve member is disposed in the internal cavity. The valve member is free floating in the internal cavity and is adapted to engage the seal seat. The valve member has an open position permitting fluid communication between the inlet port and isolation port, and is fluid flow responsive to fluid flow in the inlet port to engage the seal seat and attain a closed position preventing fluid flow between the inlet port and isolation port.

The fluid injection apparatus is adapted for use with a syringe and includes an injector and a pressure jacket associated with the injector. The injector includes a housing defining an opening for a drive piston extendable from the housing. The pressure jacket secures the syringe during an injection procedure. The pressure jacket has a distal end defining a syringe receiving opening for receiving the syringe, and a proximal end associated with the housing and generally aligned with the opening. The apparatus includes a syringe sensor adapted for engagement by the syringe when loaded into the pressure jacket. The housing may have an engagement tab adapted to engage an engagement recess in the pressure jacket to removably engage the pressure jacket with the housing. The apparatus may have one or more light sources associated with the housing for illuminating the syringe received in the pressure jacket.

The fluid delivery system includes a pressurizing device for delivering injection fluid under pressure, a low pressure fluid delivery system, and a pressure isolation mechanism. The pressure isolation mechanism includes a first lumen associated with the pressurizing device, a second lumen associated with the low pressure fluid delivery system, and a pressure isolation port. The first valve is in a normally open position permitting fluid communication between the first lumen and the second lumen and movable to a closed position when fluid pressure in the first lumen reaches a predetermined pressure level. The first valve isolates the pressure isolation port from the first lumen in the closed position. A second valve is associated with the second lumen and regulates fluid flow through the second lumen. The second valve may be a disk valve defining one or more passageways in the form of slits through the body of the disk valve.
