Liquid injector displaying input injection condition as image
First Claim
1. A contrast media injection system, comprising:
- an injection head having at least one piston drive mechanism, anda control unit, having a display screen, connected to the injection head, said control unit comprising;
screen displaying part for producing a condition screen with its vertical axis representing an injection rate of liquid and its horizontal axis representing an injection time period of the liquid;
condition entering part for accepting an input action, by an operator, for at least one injection condition including an injection rate of the liquid relative to the injection time period;
condition storing part for storing the entered injection condition;
image producing part for producing a condition-image icon having a horizontal width corresponding to the injection time period, wherein the icon has a first end and a second end;
image displaying part for displaying the condition-image icon in the condition screen on the display screen, at a vertical position in association with the injection rate and at a horizontal position in association with the injection time period; and
wherein the condition entering part is configured to accept (i) an input action for moving the icon upward or downward to thereby change the injection rate, or to accept (ii) an input action for increasing or decreasing the horizontal width of the icon thereby increasing or decreasing the injection time period.

Abstract
The preset invention provides a liquid injector in which, when an injection time period and an injection rate are entered as an injection condition, a condition image having a horizontal width corresponding to the injection time period and including the injection rate as text data is displayed in a condition screen with its vertical axis representing the injection rate and its horizontal axis representing the injection time period at a vertical position in association with the injection rate and a horizontal position in association with the injection time period. The operator easily understands instinctively the injection condition from the horizontal width and the position of the condition image, and since the condition image includes the injection rate as text data, the operator can check quickly the numerical values. Thus, the liquid injector can be provided which allows simple entry and review of the injection condition.
