NOTE: The syringe can be installed without aligning the barcodes.
NOTE: Syringes can be loaded with any of the following four configurations:
One (1) 150 mL syringe
Two (2) 150 mL syringes
One (1) 200 mL syringe
Two (2) 200 mL syringes
NOTE: If performing a contrast-only injection, place syringe onto Side A.
NOTE: The system typically takes a few seconds to read the barcode on the inserted syringe.
NOTE: When two syringes are installed at the same time, one piston will advance before the other.
2.
If Auto Advance is enabled, the piston automatically advances and engages the syringe plunger and then
advances it to the full forward position.
NOTE: If Auto Advance is not enabled, advance plunger to the end of the syringe using the piston
controls on the injector head or manual knobs.
3.
Install the filling device (e.g. spike, Quick Fill Tube) onto the end of the syringe.
4.
Insert the filling device into the fluid source.
NOTE: Refer to fluid manufacturer's instructions for use and/or package insert.
5.
Fill syringe using Auto Load or manually.
NOTE: Syringe A is the contrast syringe, and Syringe B is the saline syringe.
a.
Auto Load:
i.
Press Auto Load on the injector head.
The volume indicators on the injector head indicate how much fluid needs to be loaded to
support the displayed protocol including the amount necessary to prime the patient tubing.
Optionally, press the +/- keys to increase or decrease the amount of volume loaded.
ii.
Press Fill.
NOTE: Auto Load disables after 10 seconds of inactivity.
NOTE: The system draws in the configured Auto Load Purge Volume and then expels this volume. The
Auto Load Purge Volume should be set to 30, 20, 10, or 0 mL, depending on the filling device.
Instructions for selecting the correct volume are contained in
b. Manually:
i.
Press MOVE PISTON and use the reverse piston control to fill the syringe with the desired amount
of fluid.
NOTE: MOVE PISTON disables after 10 seconds of inactivity.
NOTE: If protocol volume is greater than fill volume, an insufficient volume communication will display
prior to ability to inject.
6.
Expel any remaining air from syringe.
NOTE: If bubbles appear in the syringe, do not hit the syringe to remove them. Reverse the plunger 3 - 5
mL, then rock the injector head on the pivot with the syringe pointed up to gather and
accumulate the small bubbles. Expel the remaining air.
