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

1 - 24 . (canceled)

25 . An injector, comprising:
an injector housing enclosing electro-mechanical drive components; at least a pair of piston elements reciprocally operated by the electro-mechanical drive components, the piston elements adapted to engage respective syringe plungers of syringes associated with the injector; an electronic control device associated with the injector for at least automated control of the piston elements; and at least one control button arranged on the injector housing, the at least one control button electronically coupled to the electronic control device associated with the injector to provide direct input to the electronic control device, the at least one control button providing control features, the at least one control button comprising at least a Refill control button configured to automatically fill the respective syringes with fluid upon actuation; and wherein the electronic control device associated with injector is preprogrammed so that automatic refill of the respective syringes occurs based upon a preprogrammed minimum volume in the respective syringes without manual actuation of the Refill control button.

26 . The injector of claim 25 , wherein the automatic refill occurs when the volume of fluid remaining in one or both of the respective syringes is less than a programmed volume.

27 . The injector of claim 25 , wherein the automatic refill occurs when the electronic control device determines that a fluid injection procedure involving the respective syringes is not likely to occur due to inactivity of a component of the injector.

28 . The injector of claim 27 , wherein the inactive component is a hand controller used to control the injector.

29 . The injector of claim 25 , wherein the electronic control device comprises a timer and associated programming to initiate the automatic refill procedure when the electronic control device determines that a fluid injection procedure involving syringes is not likely to occur due to inactivity of a component of the injector.

30 . The injector of claim 29 , wherein the inactive component is a hand controller used to control the injector.

31 . An injector, comprising:
an injector housing enclosing electro-mechanical drive components; at least a pair of piston elements reciprocally operated by the electro-mechanical drive components, the piston elements adapted to engage respective syringe plungers of syringes associated with the injector; an electronic control device associated with the injector for at least automated control of the piston elements; and at least one control button arranged on the injector housing, the at least one control button electronically coupled to the electronic control device associated with the injector to provide direct input to the electronic control device, the at least one control button providing control features, the at least one control button comprising at least a Fill/Purge control button configured to automatically fill the respective syringes with fluid and purge out air in the respective syringes upon actuation.

32 . The injector of claim 31 , wherein the at least one control button is hard-wired to the electronic control device associated with the injector.

33 . The injector of claim 31 , wherein the at least one control button comprises at least one of: Unload and Refill.

34 . An injector, comprising:
an injector housing enclosing electro-mechanical drive components; at least a pair of piston elements reciprocally operated by the electro-mechanical drive components, the piston elements adapted to engage respective syringe plungers of syringes associated with the injector; an electronic control device associated with the injector for at least automated control of the piston elements; and a graphical user interface; wherein the graphical user interface displays a plurality of control buttons having discrete functions, wherein upon activation of a first of the plurality of control buttons, the electronic control device controls the piston elements consistent with a control feature associated with the first of the plurality of control buttons, the plurality of control buttons providing control features to the attendant operator of the injector, the plurality of control buttons comprising at least a Fill/Purge control button configured to automatically fill the respective syringes with fluid and purge out air in the respective syringes upon actuation.

35 . The injector of claim 34 , wherein the graphical user interface is disposed on the injector housing.

36 . The injector of claim 34 , wherein the graphical user interface is remote from the injector housing.

37 . The injector of claim 34 , wherein at least one of the plurality of control button comprises at least one of: an Unload control button and a Refill control button.

38 . The injector of claim 37 , wherein the Refill control button is configured to cause refilling with fluid of one or more of the respective syringes upon actuation.

39 . The injector of claim 38 , wherein a refill rate and volume to refill the syringes is programmed as part of an initial data entry set-up for the electronic control device, or is preprogrammed into the electronic control device.

40 . The injector of claim 37 , wherein the Unload control button is configured to cause the piston elements to move rearward in the respective syringes to move the syringe plungers to a storage position within the respective syringes.

41 . The injector of claim 33 , wherein the Refill control button is configured to cause refilling with fluid of one or more of the respective syringes upon actuation.

42 . The injector of claim 41 , wherein a refill rate and volume to refill the syringes is programmed as part of an initial data entry set-up for the electronic control device, or is preprogrammed into the electronic control device.

43 . The injector of claim 33 , wherein the Unload control button is configured to cause the piston elements to move rearward in the respective syringes to move the syringe plungers to a storage position within the respective syringes.

44 . An injector, comprising:
an injector housing enclosing electro-mechanical drive components; at least a pair of piston elements reciprocally operated by the electro-mechanical drive components, the piston elements adapted to engage respective syringe plungers of syringes associated with the injector; an electronic control device associated with the injector for at least automated control of the piston elements; a graphical user interface; wherein the graphical user interface displays a plurality of control buttons having discrete functions; at least one physical control button arranged on the injector housing, the at least one physical control button electronically coupled to the electronic control device associated with the injector to provide direct input to the electronic control device, the at least one physical control button and the plurality of control buttons providing control features comprising at least a Fill/Purge control feature configured to automatically fill the respective syringes with fluid and purge out air in the respective syringes upon actuation.

45 . The injector of claim 44 , wherein the control features comprise at least one of: Unload and Refill.

46 . The injector of claim 45 , wherein the Refill control feature is configured to cause refilling with fluid of one or more of the respective syringes upon a
