  • Drip chamber and fluid level sensing mechanism for a fluid delivery system
    Patent number: 8147464
    Abstract: 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.

  • Fluid delivery system having a fluid level sensor and a fluid control device for isolating a patient from a pump device
    Patent number: 7556619
    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.

  • Control device for a fluid delivery system
    Publication number: 20050273056
    Abstract: The control device is used to control delivery of fluid from a fluid delivery system during a medical injection procedure. The fluid delivery system includes an injector adapted to actuate a syringe used to deliver the injection fluid to a patient. The control device is operatively associated with the injector for controlling discrete flow rates of injection fluid delivered to the patient. The control device includes a housing and an actuator associated with the housing. An electronic substrate is disposed within the housing and comprises a conductive pattern. The actuator is adapted for operative association with the conductive pattern. The conductive pattern includes a plurality of predetermined digital values corresponding to discrete flow rates of injection fluid to be delivered by the injector, such that when the actuator is actuated the actuator operatively associates with the conductive pattern for transmitting the digital values to the injector.
