Abstract

A power injector (302) with syringe communication logic (316) is disclosed. A communication with a syringe (320) for the power injector (302) may be initiated via data provided by one or more of a tilt sensor (306), a syringe clamp sensor (308), a prefilled syringe sensor (310), or an imaging energy output sensor (312).

Claims

1. A power injector comprising:

a syringe plunger driver comprising a motorized drive source;

an orientation sensor;

a communication device; and

syringe communication logic operatively interconnected with said orientation sensor and configured to initiate a syringe communication in response to said syringe communication logic identifying an occurrence of a first condition utilizing an output of said orientation sensor, wherein said communication device is operatively interconnected with said syringe communication logic, wherein said first condition is when said power injector experiences a change in orientation, and wherein said syringe communication is a communication between said communication device and a syringe data tag.

2. The power injector of claim 1, wherein said output of said orientation sensor is indicative of a change in orientation of a powerhead of said power injector.

3. The power injector of claim 1, wherein said output of said orientation sensor is indicative of a change in orientation of at least one of a powerhead of said power injector and a syringe interconnected with said syringe plunger driver, and wherein said syringe comprises said syringe data tag.

4. The power injector of claim 1, further comprising a powerhead that comprises said syringe plunger driver and said orientation sensor.

5. The power injector of claim 1, wherein said first condition is when said power injector has experienced a predetermined change in orientation.

6. The power injector of claim 1, wherein said first condition is when at least one of a powerhead of said power injector and a syringe installed on said powerhead is moving toward a tilted up position.

7. The power injector of claim 1, wherein said communication device comprises an RFD read/write device.

8. The power injector of claim 7, wherein said power injector comprises a powerhead, that in turn comprises said RFID read/write device.

9. The power injector of claim 1, further comprising:

a syringe comprising a syringe data tag, wherein said syringe communication is between said communication device and said syringe data tag.

10. The power injector of claim 1, further comprising:

a prefilled syringe sensor operatively interconnected with said syringe communication logic, wherein said syringe communication logic is further configured to initiate said syringe communication only in response to said syringe communication logic both identifying an occurrence of said first condition and identifying an occurrence of a second condition utilizing an output of said prefilled syringe sensor.

11. power injector of claim 10, wherein said second condition is when there has been at least a certain amount of attenuation of a signal that has passed through a prefilled syringe zone that would be occupied by a prefilled syringe when installed on said power injector.

12. The power injector of claim 10, wherein said prefilled syringe sensor comprises:

a transmitter; and

a receiver operatively interconnected with said syringe communication logic.

13. The power injector of claim 12, wherein said receiver is positioned to receive said signal from said transmitter after passing through said prefilled syringe zone.

14. The power injector of claim 1, further comprising:

a syringe clamp, wherein said syringe communication logic is further configured to identify an occurrence of a second condition, wherein said second condition is when said syringe clamp is in a predetermined configuration.

15. The power injector of claim 1, further comprising:

a syringe clamp disposable in each of open and closed configurations; and

a syringe clamp sensor operatively interconnected with said syringe communication logic, wherein said syringe communication logic is configured to initiate said syringe communication only in response to said syringe communication logic both identifying an occurrence of;

said first condition; and

a second condition utilizing an output of said syringe clamp sensor.

16. A method of operation for a power injector comprising:

monitoring for an occurrence of a first condition, wherein said first condition is when said power injector experiences a predetermined change in orientation; and

initiating a syringe communication between said power injector and a syringe installed on said power injector in response to said monitoring step identifying an occurrence of said first condition.

17. The method of claim 16, further comprising:

moving said power injector into a first orientation where a discharge nozzle of said syringe projects at least generally upwardly, wherein said moving said power injector into a first orientation step provides an occurrence of said first condition; and

executing at least one of first and second operations with said power injector in said first orientation, said first operation comprising purging air from said syringe and said second operation comprising loading fluid into said syringe.

18. The method of claim 17, further comprising:

moving said power injector into a second orientation after said executing step, where said discharge nozzle of said syringe projects at least generally downwardly when said power injector is in said second orientation; and

discharging fluid from said syringe with said power injector in said second orientation.

19. The method of claim 18, wherein said moving said powerhead into a second orientation step provides an occurrence of said first condition, wherein each said initiating step is executed prior to said discharging step.

20. The method of claim 16, further comprising:

sending a signal from a first location;

receiving said signal at a second location; and

monitoring said receiving step for an occurrence of a second condition, said second condition being equated with a prefilled syringe having been installed on said power injector.

21. The method of claim 20, wherein said second condition is an existence of a minimum attenuation of said signal between said sending and receiving steps.

22. The method of claim 20, further comprising:

transmitting said signal through a prefilled syringe zone, wherein said prefilled syringe zone would be occupied by said prefilled syringe when installed on said power injector, wherein said receiving step is executed after said transmitting step, and wherein said signal travels through said prefilled syringe zone after said sending step and prior to said receiving step.

23. The method of claim 20, wherein said second condition comprises at least a certain amount of attenuation of said signal after said sending step and at a time of said receiving step.

24. The method of claim 20, wherein said initiating step is executed only after and in response to an identification of each of said first and second conditions.

25. The method of claim 16, wherein said power injector further comprises a syringe clamp, and wherein said method further comprises:

monitoring said syringe clamp for an occurrence of a second condition, said second condition being when said syringe clamp is in a predetermined configuration.

26. The method of claim 25, wherein said initiating step is executed only in response to an identification of each of said first and second conditions.
