Figure 2-6, MCS+ air detector
The following air detectors are located on the MCS+ top deck.
Anticoagulant Air Detector (ACAD)
The passage of AC solution from the solution bag into the system occurs over a
series of steps. The ACAD, located on the MCS+ top deck (adjacent to the AC
pump), will monitor the AC line throughout the entire collection procedure.
Warning: If the AC solution is depleted prior to the end of the collection proce-
dure, the operator may receive a NOTICE message and an alarm, signifying that
the ACAD has detected air in the AC line tubing. Haemonetics recommends that
the collection of blood components be discontinued at this point.
Blood Line Air Detector (BLAD)
This air detector will serve a dual purpose to the operator. It is located on the top
deck of the MCS+ cabinet, to the right of the Blood pump. The BLAD will remain
“active” throughout the entire procedure but will provide a specific function at
the following moments:
!
During a DRAW cycle, the BLAD will detect the presence of fluid passing
through the blood-line tubing. This allows the system to account for the
volume of blood being pumped.
!
During a RETURN cycle, the BLAD will note the presence of any air in the
tubing leaving the centrifuge bowl. This line contains the blood being re-
turned to the donor and will pass through the donor valve after the BLAD.
When the BLAD has detected air in the tubing within normal limits, this
will signal that the bowl is empty and the RETURN cycle will be terminat-
ed.
Warning: Air detected (or lack of air detection) by the BLAD, outside of normal
limits, will stop the collection procedure and alert the operator.
