11.5 Refilling Syringe During a Procedure
Refill only using the high pressure connector tubing from an appropriately labeled fluid source within
the sterile field as described below.
1.
Disconnect the high pressure connector tubing from the catheter.
2.
Secure the distal connector of the high pressure connector tubing while using the handle and
the back of the Injector Head (but not the Manual Knob) to rotate the Injector Head in the
Purge (upright) position.
3.
Insert the distal connector of the high pressure connector tubing into the contrast medium.
4.
On the Injector Head, press the Enable button, and then press the reverse arrows on the Fill
Strip until the system fills the syringe with the desired contrast volume.
• Alternatively, on the Injector Head, press the Enable button and then press the Auto-Fill
button. 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.
NOTE:
Refer to "7.6.3.1-Auto-Fill Button with 15 mL Purge Configuration Options" for
Auto-Fill use with 15 mL Purge Configuration Options.
5.
If air bubbles remain within the syringe, including the syringe plunger, use your free hand to
gently tap the base of the Pressure Jacket to facilitate migration of the bubbles to the syringe
tip to ensure that all air bubbles are expelled.
6.
Carefully observe the FluiDots indicators to ensure that fluid is present in the syringe. Verify
that the FluiDots indicators are round in the filled portion of the syringe. The rounded shape
of the FluiDots indicators varies according to the type of contrast media, but an oblong shape
indicates the presence of air. Rounded FluiDots indicators do not indicate the total absence of
air bubbles in the syringe tip.
7.
Turn the Manual Knob clockwise to purge all air out of the syringe.
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 upright (Purge) position during filling of syringe and purging
of air.
• Purge all air out of both the high pressure connector tubing and syringe after refilling
syringe.
• Tap syringe after filling to facilitate air removal.
• Verify that the FluiDots indicators are rounded to ensure that fluid is present in the
syringe.
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, high
pressure connector tubing, and catheter.
