Abstract

A multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes an automatic refill procedure for a fluid injector system comprising a fluid injector and an operably engaged syringe. The procedure includes the step of determining, using an electronic control device operably controlling the fluid injector system, whether a fluid injection procedure involving the syringe is impending. If the electronic control device determines that the fluid injection procedure is not impending, such that the automatic refill will not interfere with the fluid injection procedure, an automatic refill of the syringe is initiated.

First claim

The invention claimed is:

1. A fluid injector system comprising a fluid injector and an syringe, comprising:
a hand controller configured to initiate at least one fluid injection procedure with the fluid injector;
at least one sensor arranged in the hand controller and configured to sense a position and/or orientation of the hand controller; and
at least one processor in communication with the hand controller and the fluid injector, the at least one processor configured to:
determine the position and/or orientation of the hand controller based at least partially on the at least one sensor;
determine if one or more of the at least one fluid injection procedures are impending based at least partially on the position and/or orientation of the hand controller; and
automatically initiate a refill of the syringe in response to determining that one or more of the at least one fluid injection procedures are not impending.

2. The fluid injector system of claim 1 , wherein the at least one processor determines that one or more of the at least one fluid injection procedures are not impending by determining that the hand controller has been set down.

3. The fluid injector system of claim 2 , wherein the at least one processor determines that one or more of the at least one fluid injection procedures are not impending by determining that the hand controller has been set down for a predetermined time period.

4. The fluid injector system of claim 1 , wherein the at least one sensor comprises at least one of the following: an accelerometer, a position sensor, an orientation sensor, a capacitance touch sensor, a thermal sensor, or any combination thereof.

5. The fluid injector system of claim 1 , wherein the processor is further configured to:
receive a request to initiate one or more of the at least one fluid injection procedures; and
transition the fluid injector to an inject state in response to the request.

6. The fluid injector system of claim 1 , wherein the processor is further configured to interrupt the refill of the syringe in response to detecting an interrupt event.

7. The fluid injector system of claim 6 , wherein the interrupt event comprises a new position and/or orientation of the hand controller.

8. A method for automatically refilling a syringe for a fluid injector system without interfering with at least one fluid injection procedure, the fluid injector system comprising a hand controller configured to initiate the at least one fluid injection procedure, the method comprising:
detecting, with at least one sensor arranged in the hand controller, a position and/or orientation of the hand controller;
determining, with at least one processor, if one or more of the at least one fluid injection procedures are impending based on the position and/or orientation of the hand controller; and
automatically refilling the syringe in response to determining that one or more of the at least one fluid injection procedures are not impending.

9. The method of claim 8 , wherein determining that one or more of the at least one fluid injection procedures are not impending comprises determining that the hand controller has been set down.

10. The method of claim 9 , wherein determining that one or more of the at least one fluid injection procedures are not impending comprises determining that the hand controller has been set down for a predetermined time period.

11. The method of claim 8 , wherein the at least one sensor comprises at least one of the following: an accelerometer, a position sensor, an orientation sensor, a capacitance touch sensor, a thermal sensor, or any combination thereof.

12. The method of claim 8 , further comprising:
receiving a request to initiate one or more of the at least one fluid injection procedures; and
transitioning the fluid injector system to an inject state in response to the request.

13. The method of claim 8 , further comprising interrupting the refilling of the syringe in response to detecting an interrupt event.

14. The method of claim 13 , wherein the interrupt event comprises a new position and/or orientation of the hand controller.

15. A fluid injector system comprising a fluid injector and an operably engaged syringe, comprising:
a hand controller configured to initiate at least one fluid injection procedure with the fluid injector;
at least one sensor arranged in the hand controller and configured to sense if the hand controller has been set down; and
at least one processor in communication with the hand controller and the fluid injector, the at least one processor configured to:
determine if the hand controller has been set down based at least partially on the at least one sensor; and
automatically initiate a refill of the syringe in response to determining that the hand controller has been set down.

16. The fluid injector system of claim 15 , wherein the at least one sensor comprises at least one of the following: an accelerometer, an orientation sensor, a position sensor, or any combination thereof, and wherein the processor determines that the hand controller has been set down based at least partially on a position and/or orientation of the hand controller.

17. The fluid injector system of claim 15 , wherein the at least one sensor comprises at least one of a capacitance touch sensor and a thermal sensor.

18. The fluid injector system of claim 15 , wherein determining that the hand controller has been set down is based on at least one of the following: a movement of the hand controller, an orientation of the hand controller, a position of the hand controller, a physical contact between the hand controller and an individual, or any combination thereof.

19. The fluid injector system of claim 15 , wherein the at least one processor is further configured to interrupt the refill of the syringe in response to detecting an interrupt event.
