Abstract

An injector system includes a powered injector, a pressurizing chamber in operative connection with the powered injection, a fluid path in fluid communication with the pressurizing chamber, and a manual control in fluid connection with the fluid path. The manual control includes at least one actuator for controlling the injector through application of force by an operator. The actuator provides tactile feedback of pressure in the fluid path to the operator via a fluid connection therewith. An injection system for use in angiography includes a source of saline, a pump in fluid connection with the source of saline to pressurized the saline, a source of contrast, a contrast valve in fluid connection with the source of contrast, a powered injector in fluid connection with the contrast valve, and a pressure isolation mechanism.

Claims

1. An injector system comprising:

a powered injector adapted to be operatively connected with a pressurizing chamber, the pressurizing chamber being adapted for fluid connection with a fluid path such that, under control of the powered injector, the pressurizing chamber is enabled to draw therein via the fluid path an injection fluid from a source thereof and to deliver therefrom via the fluid path the injection fluid to a patient;

a manual control device in operative connection with the powered injector, the manual control device comprising an actuator that is in operative connection with the powered injector and is adapted to control the flow of the injection fluid in the fluid path, the manual control device comprising a first pressure mode wherein the farther the actuator is depressed the greater the flow rate at which the injection fluid is delivered to the fluid path from the pressurizing chamber, and further comprising a second pressure mode wherein depression of the actuator causes the powered injector to deliver a preprogrammed injection of the injection fluid at a preprogrammed fixed flow rate once the actuator is depressed;

a controller; and

an automated control valve controlled by the controller and associated with the fluid path and controlled to stop flow of the injection fluid at any pressure and flow rate when no force is applied to the actuator to deliver a sharp bolus of the injection fluid.

2. The injector system of claim 1 wherein the actuator comprises a chamber in fluid connection with the fluid path and a piston disposed within the chamber, and wherein the piston is biased to an off position.

3. The injector system of claim 1 wherein the actuator comprises a piston disposed within a chamber, and the piston is biased to an off position.

4. The injector system of claim 1, further comprising an audible feedback unit in operative connection with the actuator to provide an audible signal related to the flow rate of the injection fluid.

5. The injector system of claim 1 wherein the manual control device is in operative connection with a fluid control module that is operatively connected to the powered injector.

6. The injector system of claim 5 wherein the automated control valve is part of the fluid control module.

7. An injector system comprising:

a powered injector adapted to be operatively connected with a pressurizing chamber, the pressurizing chamber being adapted for fluid connection with a fluid path such that, under control of the powered injector, the pressurizing chamber is enabled to draw therein via the fluid path an injection fluid from a source thereof and to deliver therefrom via the fluid path the injection fluid to a patient;

a pump that is adapted to pump fluid from a source of flushing fluid and to deliver therefrom via the fluid path the flushing fluid to the patient;

a manual control device in operative connection with the powered injector, the manual control device comprising an actuator that is in operative connection with the powered injector and is adapted to control the flow of the injection fluid in the fluid path, the manual control device comprising a first pressure mode wherein the farther the actuator is depressed the greater the flow rate at which the injection fluid is delivered to the fluid path from the pressurizing chamber, and further comprising a second pressure mode wherein depression of the actuator causes the powered injector to deliver a preprogrammed injection of the injection fluid at a preprogrammed fixed flow rate once the actuator is depressed;

a controller; and

an automated control valve controlled by the controller and associated with the fluid path and controlled to stop flow of the injection fluid at any pressure and flow rate when no force is applied to the actuator to deliver a sharp bolus of the injection fluid.

8. The injector system of claim 7 wherein the actuator comprises a chamber in fluid connection with the fluid path and a piston disposed within the chamber, and wherein the piston is biased to an off position.

9. The injector system of claim 7 wherein the actuator comprises a piston disposed within a chamber, and the piston is biased to an off position.

10. The injector system of claim 7, further comprising an audible feedback unit in operative connection with the actuator to provide an audible signal related to the flow rate of the injection fluid.

11. The injector system of claim 7 wherein the manual control device is in operative connection with a fluid control module that is operatively connected to the powered injector.

12. The injector system of claim 11 wherein the automated control valve is part of the fluid control module.

13. An injector system comprising:

a powered injector;

a source of an injection fluid;

a source of a flushing fluid;

a pressurizing chamber in operative connection with the powered injector;

a pump that is adapted to pump fluid from the source of flushing fluid;

a fluid path in fluid connection with the pressurizing chamber for conducting the injection fluid to the pressurizing chamber and therefrom to a patient and for conducting the flushing fluid to the patient;

a manual control device in operative connection with the powered injector and the pump, the manual control device comprising a first actuator that is in operative connection with the powered injector and is adapted to control the flow of the injection fluid in the fluid path and a second actuator that is in operative connection with the pump, the second actuator having an on state and an off state that is adapted to control the flow of the flushing fluid in the fluid path, the manual control device comprising a first pressure mode wherein the farther the first actuator is depressed the greater the flow rate at which the injection fluid is delivered to the fluid path from the pressurizing chamber, and further comprising a second pressure mode wherein depression of the first actuator causes the powered injector to deliver a preprogrammed injection of the injection fluid at a preprogrammed fixed flow rate regardless of the extent to which the first actuator is depressed;

a controller; and

an automated control valve controlled by the controller and associated with the fluid path and controlled to stop flow of the injection fluid at any pressure and flow rate when no force is applied to the first actuator to deliver a sharp bolus of the injection fluid.

14. The injector system of claim 13 wherein the manual control device is in operative connection with a fluid control module that is operatively connected to the powered injector.

15. The injector system of claim 14 wherein the automated control valve is part of the fluid control module.

16. The injector system of claim 13 wherein the first actuator comprises a piston disposed within a chamber, and the piston is biased to an off position.

17. The injector system of claim 13, further comprising an audible feedback unit in operative connection with the first actuator to provide an audible signal related to the flow rate of the injection fluid.
