摘要： A fluid path for use in a fluid delivery system is described. The fluid path may have a connecter member having a lumen, a luer member connected to the lumen, and an annular member around the luer member. The fluid path may further have a check valve in the lumen to limit fluid flow in one direction. The check valve may have a deformable stopper element and a retaining sleeve disposed in the lumen of the connecter member. The retaining sleeve may have a central bore and a distal end against which the stopper element sits to prevent fluid flow through the lumen until a sufficient fluid pressure is present to deform the stopper element and unseat the stopper from the retaining sleeve. One or more grooves may be present in the receiving cavity. The fluid path may further have a drip chamber, a second tubing section, and a spike.

摘要： The fluid injector system includes a source of injection fluid, a pump device, a fluid control device operably associated with the pump device, and a fluid path set in fluid connection with the source of injection fluid and the pump device. The fluid path set includes a drip chamber including an elongated body having a top end, a bottom end and a raised projection, the raised projection being substantially rectangular in shape and extending longitudinally from the top end along the drip chamber body and terminating adjacent to the bottom end. A fluid level sensing mechanism is operably associated with the fluid control device, and includes a drip chamber support for supporting the drip chamber body and a fluid level sensor associated with the drip chamber support. The drip chamber support is adapted to support the drip chamber body such that the raised projection is in operational contact with the fluid level sensor and the fluid level sensing mechanism is operable to transmit ultrasonic or light energy through the raised projection to be sensed by the fluid level sensor for sensing the injection fluid level in the drip chamber.

摘要： A fluid delivery system which 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 valve housing having a first port associated with the pressurizing device, a second port associated with the low pressure fluid delivery system, an outlet port associated with a patient, and a pressure isolation port for connection with a pressure transducer. A first valve in a normally open position permits fluid communication between the first port and the second port and is movable to a closed position when fluid pressure in the first port increases to a predetermined pressure level. The first valve isolates the pressure isolation port from the first port when in the closed position. A second valve is associated with the second port and regulates fluid flow through the second port.

摘要： 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.

摘要： A multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes a powered injector, a pressure jacket support, a syringe pressure jacket, and a syringe. The pressure jacket support includes a front plate and a rear plate. The rear plate is connected to the injector and the front plate is spaced from the rear plate and defines a slot. The syringe pressure jacket has a proximal end pivotally connected to the rear plate so that a distal end of the pressure jacket pivots relative to the front plate. The syringe has a syringe body with a distally extending discharge conduit. With the syringe disposed in a barrel of the pressure jacket, pivotal movement of the pressure jacket results in the distal end thereof pivoting toward the front plate to place the discharge conduit within the slot in the front plate.
