Abstract

A fluid injector system includes a control device operably associated with at least one drive component for use in actuating a plurality of fluid containers in fluid communication with a patient through an administration line. The control device includes at least one processor programmed or configured to enable programming of a diagnostic injection protocol comprising one or more phases according to which at least one of the first and the second fluid containers are selectively actuatable by the at least one drive component to enable injection of at least one of a first fluid and a second fluid into the patient. The control device is further programmed or configured to enable selection and commencement of at least partial preloading into the administration line of at least one of the first fluid and the second fluid in accordance with the one or more phases of the diagnostic injection protocol.

First claim

We claim:

1. A fluid injector system comprising:
a control device operably associated with at least one drive component for use in actuating a plurality of fluid containers, the plurality of fluid containers capable of being placed in fluid communication with a patient through an administration line with a first of the fluid containers capable of being filled with a first fluid comprising a contrast solution and a second of the fluid containers capable of being filled with a second fluid comprising a flushing agent; and
the control device including at least one processor programmed or configured to:
enable programming of a diagnostic injection protocol comprising one or more phases according to which at least one of the first and the second fluid containers are selectively actuatable by the at least one drive component to enable injection of at least one of the first fluid and the second fluid via the administration line 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;
prime the administration line with the second fluid;
enable selection and commencement of at least partial preloading into the administration line of a predetermined volume of at least one of the first fluid and the second fluid in accordance with the one or more phases of the diagnostic injection protocol; and
initiate the diagnostic injection protocol to deliver the predetermined volume of at least one of the first fluid and the second fluid and any remaining volume of at least one of the first fluid and the second fluid in accordance with the one or more phases of the diagnostic injection protocol to the patient via the administration line;

wherein the at least one processor is further programmed or configured to calculate a total volume of the at least one of the first fluid and the second fluid to be injected according to the diagnostic injection protocol such that, upon commencement of at least partial preloading, the at least one processor:
upon determining that the total volume of the at least one of the first fluid and the second fluid to be injected according to the diagnostic injection protocol is equal to the capacity of the administration line, preloads into the administration line the total volume of the diagnostic injection protocol in accordance with the one or more phases thereof and thereby expels from the administration line a volume of the second fluid used in the priming of the administration line therewith;
upon determining that the total volume of the at least one of the first fluid and the second fluid to be injected according to the diagnostic injection protocol is less than the capacity of the administration line, preloads into the administration line the total volume of the diagnostic injection protocol in accordance with the one or more phases thereof followed by a supplemental volume of the second fluid equal to the capacity of the administration line minus the total volume of the diagnostic injection protocol and thereby expels from the administration line the volume of the second fluid used in the priming of the administration line therewith; and
upon determining that the total volume of the at least one of the first fluid and the second fluid to be injected according to the diagnostic injection protocol is greater than the capacity of the administration line, preloads into the administration line as much of the at least one of the first fluid and the second fluid in accordance with the one or more phases of the diagnostic injection protocol as a capacity of the administration line will allow and retains within the programming a remaining portion of the diagnostic injection protocol until the diagnostic injection protocol is performed on the patient and thereby expels from the administration line the volume of the second fluid used in the priming of the administration line therewith.

2. The fluid injector system of claim 1 , further including a user interface operably associated with the at least one processor, the user interface being configured to accept a plurality of user inputs associated with control of a plurality of operations of the fluid injector system, wherein a set of the plurality of user inputs is associated with the control of a corresponding set of the plurality of operations involved with the enabling of the selection and the commencement of the at least partial preloading into the administration line of the at least one of the first fluid and the second fluid in accordance with the one or more phases of the diagnostic injection protocol.

3. The fluid injector system of claim 2 , wherein the set of the plurality of user inputs includes:
a select preloading command upon entry of which into the user interface the control device readies the fluid injector system for the at least partial preloading of the diagnostic injection protocol into the administration line;
a commence preloading command upon entry of which into the user interface after the select preloading command the control device actuates the plurality of fluid containers and thereby commences the at least partial preloading into the administration line of at least one of the first fluid and the second fluid in accordance with the one or more phases of the diagnostic injection protocol; and
a disable preloading command upon entry of which into the user interface after the select preloading command the control device disables an effect of the select preloading command.

4. The fluid injector system of claim 2 , wherein the user interface is configured to display information associated with a status of the at least partial preloading into the administration line of at least one of the first fluid and the second fluid in accordance with the one or more phases of the diagnostic injection protocol.

5. The fluid injector system of claim 2 , wherein the user interface is configured to display at least one of:
the total volume of the at least one of the first fluid and the second fluid to be injected according to the diagnostic injection protocol; and
for each of the one or more phases of the diagnostic injection protocol, a particular volume of the at least one of the first fluid and the second fluid therein and a flow rate at which the particular volume is to be injected into the patient during administration thereof.

6. The fluid injector system of claim 1 , wherein the first of the fluid containers comprises a syringe and the second of the fluid containers comprises a syringe.

7. A computer program product for enabling at least partial preloading into an administration line of at least one of a first fluid and a second fluid in accordance with a one or more phases of a diagnostic injection protocol, 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 programming of the diagnostic injection protocol into a control device of a fluid injector system, the control device operably associated with at least one drive component for use in selectively actuating a plurality of fluid containers, the plurality of fluid containers configured for being placed in fluid communication with a patient through the administration line with a first of the fluid containers capable of being filled with the first fluid comprising a contrast solution and a second of the fluid containers capable of being filled with the second fluid comprising a flushing agent;
prime the administration line with the second fluid;
enable selection and commencement of at least partial preloading into the administration line of a predetermined volume of at least one of the first fluid and the secon
