10.2 Filling and Purging the Mark 7 Arterion or Twist & Go Syringe
Operators can fill a syringe using the Fill Strip or the Auto-Fill button.
1.
Use the handle and the back of the Injector Head (but not the Manual Knob) to rotate the
Injector Head to the Purge (upright) position.
2.
Remove the Quick Fill Tube from the syringe package.
3.
Remove the dustcap from the syringe tip and set aside maintaining sterility.
4.
Attach the short end of the Quick Fill Tube to the syringe tip.
NOTE:
The Quick Fill Tube can be attached without repositioning the FasTurn nut (H) (Mark
7 Arterion Syringe only) attached to the syringe tip.
5.
Insert the long end of the Quick Fill Tube into the fluid source (usually contrast media). Raise
the contrast bottle until the Quick Fill Tube is fully inserted into the contrast.
NOTE:
Use a Quick Fill Tube or equivalent device to reduce the volume and size of air
bubbles drawn into the syringe during filling. It is more difficult to remove the air
bubbles if you use smaller diameter tubes or a tube longer than 10 in. (25 cm.)
6.
On the Injector Head, press the Enable button (A), and then press and hold the reverse
arrows (B) on the Fill Strip (C) until the system fills the syringe with the desired contrast
volume.
• Alternatively, on the Injector Head, press the Enable button and then press and release
the Auto-Fill button (I). The Mark 7 Arterion fills the syringe with the preconfigured
contrast volume at the preconfigured speed. The volume and speed are configured from
the Display Control Unit
Options tab.
7.
If required, use your free hand to gently tap the base of the Pressure Jacket to facilitate
migration of air bubbles remaining within the syringe and on the syringe plunger to the
syringe tip.
Air Embolism Hazard - Serious Patient Injury or Death May Result.
• Ensure that one operator is designated as being responsible for filling and refilling the
syringe. Do not change operators during the procedure. If an operator change must occur,
ensure that the new operator verifies that the fluid path is purged of air.
• Ensure that patient is not connected while purging air from syringe, or engaging or
advancing plunger.
• Orient the Injector head to the Purge (upright) position during filling of syringe and purging
of air.
• Purge all air out of syringe and any and all disposables after filling.
• Tap syringe after filling to facilitate air removal.
• Verify that the FluiDots indicators are rounded to ensure that fluid is present in the
syringe.
Bloodborne Contamination Hazard - Serious patient and/or worker injury or death may
result.
• Do not grasp the drop front, pressure jacket, or syringe to rotate the Injector Head.
Cross Contamination Hazard - Serious patient and/or worker injury or death may result.
• Use caution when removing air from the syringe. Component damage may result from the
use of tools during air removal.
Environmental Contamination Hazard - Minor or moderate patient and/ or worker injury may
result.
• Follow sterile technique principles, specifically, maintain sterility of the syringe tip,
plunger, syringe barrel internal surface, and Quick Fill Tube.
