  • Publication number: 20080091142
    Abstract: An injector system includes a source of injection fluid, a pump device, a fluid path set disposed between the source of injection fluid and the pump device, a fluid control device operatively associated with the fluid path set and a hand held control device for controlling the flow rate of the injection fluid. The hand held control device includes a piston slideably disposed within a chamber and adapted to engage a switch that controls the flow rate of the injection fluid. The fluid control device is adapted to permit purging of air from the fluid path set and to stop flow of the injection fluid to a patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The fluid control device is preferably part of the fluid path set between the source of injection fluid and the pump device.

  • Publication number: 20050234407
    Abstract: The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.

  • Publication number: 20050104444
    Abstract: A pressure isolation mechanism for use in a medical procedure includes a lumen, an isolation port in fluid connection with lumen, and a valve having a first state and a second state. The first state occurs when the lumen and the isolation port are connected. The second state occurs when the lumen and the isolation port are disconnected. The lumen remains open for flow of fluid therethrough in the first state and in the second state. The valve is normally in the first state and is switchable to the second state when fluid pressure in the lumen reaches a predetermined pressure level. A pressure transducer can be in fluid connection with the isolation port of the pressure isolation mechanism A fluid delivery system includes a manually operated syringe and a pressure isolation mechanism as described above.
