9.2.1 Fluid Detection Methods
The Stellant syringe aids in determining the presence of fluid by using two methods:
• The use of clear material allows visual detection of air inside of the syringe.
• MEDRAD
®
FluiDots on the syringe’s wall appear round when the syringe is full of fluid and
oval when the syringe is empty.
9.2.1.1 Using MEDRAD
®
FluiDots
NOTE:
If using the optional heat maintainer, ensure that the heat maintainer is positioned in such a
way that at least one of the FluiDots is visible.
FluiDots should be observed as part of an arming procedure. When the FluiDots are viewed through an
empty syringe, the dots appear as small, narrow ellipses, as illustrated in Figure 9 - 3: FluiDots. When
viewed through a full syringe, the dots become larger, almost round.
Environmental Contamination Hazard - Serious patient or worker injury or death may result.
• Follow aseptic technique when handling disposable components. Specifically, maintain
sterility of all disposable components.
• Do not disassemble any disposable components.
• Visually inspect contents and package before each use.
Bacterial Contamination Hazard - Serious patient and/or worker injury or death may result.
• Syringes are not intended to be used as storage containers. Do not use syringes to
store fluids.
Mechanical Hazard - Serious patient injury could result from leaks or ruptures during an
injection.
• Use only disposables supplied by Bayer. Refer to "Sterile Disposables" .
• Use only syringes and tubing with a pressure rating greater than the maximum
programmable pressure limit of the injection system, which is 325 psi (2241 kPa).
• Use catheters with pressure ratings compatible with this system. Refer to "Maximum
Flow Rate Performance" and "Programmable Pressure System Performance" .
Adverse Reaction Hazard - Serious patient injury or death may result.
• Check the patient history for any evidence of allergy to injectable fluid sources.
Compromised Efficacy - Serious patient injury may result.
• Programming or loading an incorrect fluid source or concentration may result in patient
injury or suboptimal imaging.
Vessel Hazard - Serious patient injury or death may result
• Use catheters and connectors with pressure ratings compatible with this system. Refer to
"Maximum Flow Rate Performance" and "Programmable Pressure System Performance" .
Mechanical Hazard - Serious patient injury could result if the syringe is not properly
engaged.
• Ensure the syringe is properly snapped into the front of the injector head before injecting.
Improper engagement or rotating syringe may cause the syringe to leak, to become
damaged, or to come off during the injection, and result in an under-volume delivery and
the syringe becoming a flying projectile.
