Abstract
Provided is a method for delivering a medical fluid. The method includes delivering a fluid volume, which includes contrast and/or a flush fluid, at a preselected total volumetric flowrate during a first duration of a fluid delivery procedure. The amount of the contrast agent and the flush fluid in the fluid volume can be controllably varied during the first duration of the fluid delivery procedure so as to substantially maintain a preselected total volumetric flowrate throughout the first duration of the fluid delivery procedure. Also provided is a fluid delivery system capable of performing this method.
Claims19
A method for delivering a medical fluid, comprising:
- delivering a fluid volume at a preselected total volumetric flowrate during a first duration of a fluid delivery procedure, wherein the fluid volume is comprised of a volumetric amount of a contrast agent and, optionally, a volumetric amount of a flush fluid;
- controllably varying the volumetric amount of the contrast agent in the fluid volume during the first duration of the fluid delivery procedure;
- and
- controllably varying the volumetric amount of the flush fluid in the fluid volume during the first duration of the fluid delivery procedure so as to substantially maintain the preselected total volumetric flowrate throughout the first duration of the fluid delivery procedure.
A fluid delivery system, comprising:
- a fluid administration device adapted to deliver a fluid volume, wherein the fluid volume comprises a volumetric amount of a contrast agent and, optionally, a volumetric amount of a flush fluid;
- and
- a controller in communication with the fluid administration device, wherein the controller comprises a processor and a non-transitory machine-readable storage medium, wherein the non-transitory machine-readable storage medium comprises instructions that, when executed by the processor, enable the fluid administration device to:
- deliver the fluid volume at a preselected total volumetric flowrate during a first duration of a fluid delivery procedure;
- controllably vary the volumetric amount of the contrast agent in the fluid volume during the first duration of the fluid delivery procedure;
- and
- controllably vary the volumetric amount of the flush fluid in the fluid volume during the first duration so as to substantially maintain the preselected total volumetric flowrate throughout the first duration of the fluid delivery procedure.
