Connecting The Extracorporeal Blood Circuit - Fresenius Medical Care 2008K Operator's Manual

Connecting the Extracorporeal Blood Circuit

For the following set of instructions, refer to Figure 10 "The Blood Pump Module" on page
33 regarding the names of the various blood pump parts and Figure 12 – The Level Detector
Module on page 35 regarding the names of the various module parts.
To connect the bloodlines:
Warning! Use aseptic technique.
Note: These are general instructions are for a new, dry-pack dialyzer. Your specific
procedure should be consistent with the dialyzer manufacturer's instructions.
Arterial Bloodline Setup
1. Close medication port clamp
2. Snap the arterial chamber into its holder
3. Connect the arterial monitor line to the arterial pressure port using a transducer protector
and verify that the monitor line is unclamped.
Warning! Transducer protectors should be used between transducers and each pressure
monitor line of the extracorporeal system to prevent the transducers from getting wet. Wet
transducer protectors must be replaced, as they will cause inaccurate pressure readings. If
the external transducer protector and the internal transducer should become contaminated
with blood, the transducer protectors must be replaced, and the transducer must be
disinfected or replaced.
4. Open the blood pump door.
Warning! Inspect the blood pump rotor for proper operation (tubing guide posts not bent,
rollers move freely, crank lever moves freely). Bent or loose tubing guide posts can damage
bloodlines. Replace rotor if necessary. See page 127 for rotor diagram.
5. If necessary, set the pump for the diameter of the blood pump segment.

Press the Up () and Down () keys on the blood pump module simultaneously.
The display will flash.

Press the Up () or Down () key on the blood pump module until the diameter of
the pump segment being used is displayed.
6. Load the blood pump segment:
a. Press and hold the Start/Stop key on the blood pump module to align rotor for line
insertion.
b. Grasp the pump segment and, using thumb pressure, position it behind the left yoke
by pressing the tubing retainer inward. Be sure the end of the segment clears the
bottom of the yoke.
Warning! Make sure the collar of the pump segment is positioned below the bottom of the
yoke. This will minimize the possibility of the segment kinking during pump operation.
c. Press and hold the Start/Stop key. The rotor will rotate to the 5 o'clock position and
stop. Relieve pressure on the retainer and release the segment. The beginning of the
pump segment should be secured between the left yoke and the tubing retainer.
