Priming Detector Calibration; Occlusion Adjustment, Blood Pump - Gambro AK 95 S Service Manual

Priming Detector calibration

1. Start the AK 95 S, enter the Service
menu and select Calibrations.
2. Select Transducer, External and
PRIMING DETECTOR from the selection
diagram.
3. Press to start calibration routine.
4. The display shows:
INSERT TUBE
Press SELECT to confirm
5. Insert an empty tube in the priming
detector and press
Use the normal tube from the blood line.
6. The calibration is now done automatically
and the calibration factor is writen into
the EEPROM.
7. When the info. display shows "EEPROM
STORAGE COMPLETED", the calibration
is completed.
8. Press to exit.
If an technical error is detected, the calibration
must be restarted, or the priming detector
replaced.

Occlusion adjustment, blood pump/

infusion pump
Check surface on the roller at the pump rotor, if
it is damaged exchange the unit. The roller unit
should easily go back to upper end position when
it has been pressed down to end position, ex-
change unit if it gets stuck in any position.
Note! If the blood lines/infusion lines have a
different wall thickness, the occlusion of the
blood pump must be adjusted to the right size.
Use the gauge pins (stop/go) available in the kit
K40158001. The kit includes following three
different gauge pins:
T = 1.1 (Stop pin = 1.1*2*0.7 = 1.5mm)
T = 1.6 (Stop pin = 1.6*2*0.7 = 2.2mm)
T = 2.0 (Stop pin = 2.0*2*0.7 = 2.8mm)
T = wall thickness of the blood tubing
Use following formula to calculate which gage
pin to use:
2 * wall thickness * 0,7 (mm)
Check the range between the blood pump rollers
and the path according to the picture below.
Adjust range between the blood pump rollers and
the path if it is necessary.
The GO pin should barely pass within the cali-
brating area.
The STOP pin is NOT allowed to pass in any
point within the calibrating area.
Note! Put grease on the GO and STOP pins
when not used and store gage in plastic bag to
prevent it from corroding.
