Caution: If you are using a Single Knob Single Needle Blood Pump module, you must
make sure that the pump is set for the diameter of the blood pump segment.
Note: If you are using a Single Knob Single Needle Blood Pump module, you must
manually load the single needle blood pump segment: Thread the single needle blood pump
segment into the single needle pump using the rotor latch (see Figure 58 #1 on page 130) to
rotate the single needle pump rotor clockwise. Make sure the left and right pump segment
connectors are positioned below the left and right yokes and the line is free from kinks.
3. Load the single needle blood pump segment:
a. Press and hold the Start/Stop key on the Single Needle 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.
Warning! Keep fingers free of rotor while it is turning to avoid possible injury.
d. Press and hold the Start/Stop key again and the rotor will rotate one full turn to
automatically position the remainder of the segment within the pump housing. After
loading, any extra pump segment tubing length should be on the right side of the
pump.
e. Release the Start/Stop key when the pump segment has been inserted along the track
inside the pump housing all the way to the right yoke.
f. Grasp the remaining portion of the segment and, using thumb pressure in a manner
similar to step b, position it behind the right yoke.
g. Release the tubing retainer and close the pump door. Be sure the pump segment is
free of kinks and both ends of the segment extend below the yoke.
4. On the "Test & Options" screen, select the Single Needle toggle-button to set it to 'On'
and press the CONFIRM key to confirm the change.
5. Press the Start/Stop key on the Arterial Blood Pump module to start the blood pump.
Note: If using a Single Knob Single Needle Blood Pump module, set the single needle
blood flow rate to approximately 20% higher than the arterial blood pump rate. The blood
flow rate displayed on the Arterial Blood Pump module with the Single Needle option set to
'On' equals the average blood flow rate for both pumps.
Note: Allow the system to recirculate several times before connecting the patient to assure
that the extracorporeal circuit is ready.
