Simulated contrast injection medium

摘要

A medical fluid injection system may include a powered injector and a fluid reservoir that contains a simulated contrast medium. The simulated contrast medium may exhibit a fluid flow property substantially equal to that of an active contrast medium but be devoid of any active contrast agent that provides contrast during diagnostic imaging. During operation, a syringe in the powered injector may be filled with the simulated contrast medium and then evacuated to discharge the simulated contrast medium from the syringe. The simulated contrast medium may be used to test and evaluate the performance of the powered injector prior to use in a medical procedure without exposing personnel to an active contrast agent or creating medical waste that contains the active contrast agent.

1. A system comprising:
a powered injector that includes a plunger, a motor configured to advance and retract the plunger, and a syringe holder configured to hold a syringe so that the plunger moves within the syringe; a fluid reservoir containing a simulated contrast medium in fluid communication with the syringe, the simulated contrast medium exhibiting a fluid flow property substantially equal to that of an active contrast medium but being devoid of any active contrast agent that provides contrast during diagnostic imaging; and a processor configured to retract the plunger within the syringe so as to draw the simulated contrast medium from the reservoir into the syringe and advance the plunger within the syringe so as to discharge the simulated contrast medium from the syringe.
