US 12,002,560 B2 · System and method for testing blood vessel access using powered fluid injector systems

Abstract

A fluid injector system has a controller for operably controlling the injection of contrast and/or saline into a patient. The controller allows a user to program a diagnostic injection procedure having one or more phases according to which the contrast and/or saline will be injected into the patient so as to effect enhancement of a region thereof during an imaging procedure. It further allows the user to program a test injection procedure to be performed prior to the diagnostic injection procedure. The test injection procedure is implementable as: (a) a variable single phase test injection in which the rate at which the saline is to be delivered is selectable prior to and may be varied during performance thereof; and/or (b) a multi-phase test injection in which the rate at which the saline is to be delivered is selectable for each phase of the multi-phase test injection prior to performance thereof.

Dependent claims

A fluid injector system comprising:

a controller operably associated with at least one drive member by which at least one fluid contained within at least one fluid container is injectable into a patient,
the controller including a programming system for enabling programming of at least one diagnostic injection procedure comprising at least one diagnostic injection phase according to which the at least one fluid is to be injected into the patient so as to effect enhancement of at least one region of interest thereof over a scan duration of a diagnostic imaging procedure;
and
the programming system for further enabling programming of a test injection procedure to be performed prior to the diagnostic injection procedure, wherein the test injection procedure is implementable as:
a variable single phase test injection in which a flow rate at which the at least one fluid is to be delivered is selectable prior to performance of the variable single phase test injection and may be varied during performance of the variable single phase test injection.

2 more elements

A computer program product for enabling programming of a test injection procedure to be performed using a fluid injector system prior to a diagnostic injection procedure, the computer program product comprising at least one non-transitory computer-readable medium comprising one or more instructions that, when executed by at least one processor, cause the at least one processor to:

enable a user, via the fluid injector system, to select the test injection procedure to be performed as a variable single phase test injection such that upon selecting
the variable single phase test injection, a flow rate at which at least one fluid is to be delivered during the variable single phase test injection is selectable prior to performance of the variable single phase test injection and may be varied during performance of the variable single phase test injection.
