Fluid Injection System Providing Visual Stimuli
a technology of visual stimuli and fluid injection, which is applied in the direction of instruments, process and machine control, diagnostics, etc., can solve the problems of lack of flexibility in developing and administering infusion protocols to patients, the inability to recognize the makeup of a given protocol quickly and efficiently, and the high cost of contrast medium

Benefits of technology
This solution provides a high degree of flexibility in creating infusion protocols, allowing for a wide range of possible combinations of contrast and flushing medium phases, including pauses and holds, which enhances the convenience and effectiveness of medical imaging procedures by optimizing fluid administration and reducing operator interaction and errors.
Problems solved by technology
As is known conventionally, it is often desirable to flush from the tubing of an infusion system a residual quantity of contrast medium that remains there after a given infusion procedure, as contrast medium tends to be expensive and its efficient use, without waste, is often seen as a top priority.
Of late, however, some disadvantages have been noted in connection with the “SPECTRIS” control system and other related systems.
Not the least of these is the lack of flexibility in developing and administering infusion protocols to a patient, as the “SPECTRIS” system would allow no more than two distinct phases for each medium, and no single phase of flushing medium infusion could take place between two different phases of contrast medium infusion.
A further disadvantage has been recognized in that the aforementioned phases will typically be administered one after the other without the opportunity for an intermediate pause or hold between phases.
This would appear to limit the convenience and utility of the system in question in many respects.
However, this appears to be even less flexible than the “SPECTRIS” system in that only protocols consisting of no more than one contrast medium infusion and no more than one flushing medium infusion appear to be permitted.

Embodiment Construction
[0036]FIGS. 1 and 2 generally illustrate a conventional MRI injector system arrangement, such as is disclosed in U.S. Pat. No. 5,494,036 to Uber et al, the contents of which are incorporated herein by reference. A magnetic resonance injector system is shown generally at 10. The MRI system includes a system controller 12, which incorporates a computer 14 and a battery-charging unit 16. The system controller 12 is located externally of the imaging room 17, the imaging room being shielded from electromagnetic interference by a shield 18.
[0037] Isolation can be achieved by completely enclosing the room with copper sheet material or some other suitable, conductive layer such as wire mesh. Communication line 20, connects the system controller 12 with an external infrared / optical communications transceiver 22. The shielded imaging room 17 also incorporates a patient viewing window 24 in the shield 18 which allows an operator to view the imaging room. The window 24 can be formed by sandwic...

A fluid injection system includes an injector comprising a drive mechanism and an illumination device, a fluid container operably associated with the drive mechanism, and a control device operably associated with the drive mechanism. The control device comprises a computer screen having at least one element affiliated with the illumination device. The illumination device and the at least one element emit light of the same color. Further, a method of operating an injector system providing visual stimuli corresponding to a programmed injection protocol includes perceiving visual stimuli provided by an injector or a control device of the injector system, recognizing a pattern provided by the visual stimuli, correlating the recognized pattern to the programmed injection protocol, determining whether the programmed injection protocol is a desired injection protocol, and initiating the programmed injection protocol, if it is determined that the programmed injection protocol is the desired injection protocol.
