First Claim
Patent Images
1. A power injector, comprising:
- a powerhead;
a syringe plunger driver;
a graphical user interface; and
control logic configured to;
a) execute a medical fluid delivery protocol, wherein said medical fluid delivery protocol comprises at least one phase configured to deliver a programmed volume of a medical fluid at a programmed target flow rate, and wherein said power injector attempts to provide said target flow rate in an execution of said at least one phase; and
b) display a first output on said graphical user interface, wherein said first output comprises a numerical representation of a relationship between said target flow rate of said at least one phase of said medical fluid delivery protocol and a current flow rate that exists during an execution of said at least one phase of said medical fluid delivery protocol, wherein said numerical representation comprises a single number.

Abstract
A flow rate assessment protocol (140) that may be utilized by a power injector (10) is disclosed. This flow rate assessment protocol (140) monitors a flow rate (156) during execution of a medical fluid delivery protocol (154). This monitored flow rate is compared with a target flow rate (158). A comparative output of this monitored flow rate and target flow rate is displayed (160), for instance on a graphical user interface (11).

15. A power injector, comprising:
-
a powerhead; a syringe plunger driver; a graphical user interface; and control logic configured to;
a) execute a medical fluid delivery protocol, wherein said medical fluid delivery protocol comprises at least one phase configured to deliver a programmed volume of a medical fluid at a programmed target flow rate, and wherein said power injector attempts to provide said target flow rate in an execution of said at least one phase; and
b) display a first output on said graphical user interface, wherein said first output comprises a numerical representation of a relationship between said target flow rate of said at least one phase of said medical fluid delivery protocol and a current flow rate that exists during an execution of said at least one phase of said medical fluid delivery protocol, wherein said numerical representation comprises an expression of said current flow rate as a percentage of said target flow rate. - View Dependent Claims (16)

17. A power injector, comprising:
-
a powerhead; a syringe plunger driver; a graphical user interface; a data entry device; and control logic configured to;
a) execute a medical fluid delivery protocol, wherein said medical fluid delivery protocol comprises at least one phase configured to deliver a programmed volume of a medical fluid at a programmed target flow rate, and wherein said power injector attempts to provide said target flow rate in an execution of said at least one phase;
b) display a first output on said graphical user interface, wherein said first output is comparative of said target flow rate of said at least one phase of said medical fluid delivery protocol and a current flow rate that exists during an execution of said at least one phase of said medical fluid delivery protocol;
c) discontinue execution of said medical fluid delivery protocol upon occurrence of a first flow rate variance between said target flow rate and said current flow rate; and
d) generate a message, in addition to said first output, upon occurrence of a second flow rate variance between said target flow rate and said current flow rate, wherein said second flow rate variance is of a smaller magnitude than said first flow rate variance. - View Dependent Claims (18, 19, 20)
