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.

Claims

1. A contrast media injection system, comprising;

an injection head having at least one piston drive mechanism, and

a control unit having a display screen, connected to the injection head,

said control unit configured to;

produce a condition graph with its vertical axis representing an injection rate of liquid and its horizontal axis representing an injection time period of the liquid;

store an injection condition;

produce a condition-image icon including text data of at least injection rate or injection volume;

display the condition-image icon in the condition graph on the display screen;

accept an input action by an operator to modify at least one injection condition parameter of the injection condition;

display a plurality of body-section icons in schematic images in the shape of a human body;

accept a selection of one of said body-section icons;

display at least one icon for regions to be imaged when one of the body-sections is selected;

accept a selection of one of said icons for regions to be imaged; and

display the condition-image icon including at least one injection condition parameter associated with the selected region to be imaged.

2. The contrast media injection system of claim 1, wherein said control unit is further configured to display a numeric keypad on the display screen for modifying the injection condition parameter.

3. The contrast media injection system of claim 1, wherein said display screen is a touch panel screen.

4. The contrast media injection system of claim 1, wherein the injection head comprising;

a first piston drive mechanism for contrast media injection; and

a second piston drive mechanism for saline injection.

5. The contrast media injection system of claim 1, wherein the injection head is configured to hold a pre-filled syringe.

6. The contrast media injection system of claim 1, wherein the injection head is configured to hold an empty syringe.

7. A contrast media injection system, comprising:

an injection head having at least one piston drive mechanism, and

a control unit having a display screen, connected to the injection head,

said control unit configured to;

produce a condition graph with its vertical axis representing an injection rate of liquid and its horizontal axis representing an injection time period of the liquid;

store an injection condition;

produce a condition-image icon including text data of at least injection rate or injection volume;

display the condition-image icon in the condition graph on the display screen;

accept an input action by an operator to modify at least one injection condition parameter of the injection condition;

display a plurality of body-section icons in schematic images in the shape of a human body;

accept a selection of one of said body-section icons;

accept an input of patient weight data;

accept an input of injection time data; and

display the condition-image icon including at least one injection condition parameter associated with at least one of the selected body-section, the patient weight, or the injection time.

8. The contrast media injection system of claim 7, wherein said control unit is further configured to display a numeric keypad on the display screen for modifying an injection condition parameter.

9. The contrast media injection system of claim 7, wherein said display screen is a touch panel screen.

10. The contrast media injection system of claim 7, wherein the injection head comprises:

a first piston drive mechanism for contrast media injection; and

a second piston drive mechanism for saline injection.

11. The contrast media injection system of claim 7, wherein the injection head is configured to hold a pre-filled syringe.

12. The contrast media injection system of claim 7, wherein the injection head is configured to hold an empty syringe.
