automatically,” and the Last Bowl function is terminated.
If the volume of RBCs is sufficient to start a Concentrate cycle automatically but not to complete
filling the bowl, the system alerts the operator with the message, “RBC bag empty. Bowl not
filled”. In this case, the operator can decide to either process a partial bowl (with normal or
double saline solution volume) or to discard the residual volume in the bowl.
• At the end of the Concentrate phase, the Wash phase is activated automatically without any
intervention required by the operator.
• At the end of the Wash phase or at the end of the Fat Removal phase (if the Pfat protocol is in
use), the Empty phase is automatically initiated. Once the bowl is empty, the Empty phase
continues to empty the Empty line without any intervention required by the operator. The Last
Bowl function is then complete and deactivated.
While the Last Bowl function is active, the Last Bowl symbol is displayed in the status area.
The Last Bowl function may be interrupted in the following ways:
• By pushing the Stop button.
• By activating the Emergency function.
• By switching to the Manual operating mode.
CAUTION
The Concentration function reprocesses already collected red blood cells
subjecting them again to the mechanical action of the pump and the
centrifuge. The repeated use of the Concentration function on the same red
blood cells might lead to them being damaged and therefore to their loss.
WARNING
The use of the Last Bowl function is recommended only to complete
the case, with the following conditions: The reservoir is empty, no
more blood is expected to be collected, and sufficient red cells in
saline solution are available in the RBC bag to compete the
Concentrate cycle.
WARNING
In case a partial bowl is washed, the hematocrit of the collected
blood as well as the removal of waste components might be lower
than expected.
WARNING
The maximum volume in the RBC bag is 1 liter. To avoid explosions,
check the level inside the bag carefully before activating the Last
Bowl function.
WARNING
The Last Bowl function automatically activates a second Empty
phase at the end of the first Empty phase. Carefully monitor the air
in the RBC bag in case of repeated activation of the Last Bowl
function.
