Draw Phase
At the beginning of each draw phase, the pressure cuff will inflate
temporarily above the default value to remind the donor that it is
now time to start squeezing. If present, the donor squeeze icon flashes
on the donor display, on each side of the instrument to indicate
that the donor should squeeze and release his or her fist to aid
blood flow.
At the start of collection, the instrument primes the kit with blood,
displacing the other fluids already in the kit. As whole blood (WB)
is drawn from the donor, anticoagulant (AC) is added at a WB:AC
ratio of 11:1.
During the draw phase, anticoagulated blood is simultaneously
pumped into the in-process container and the separation chamber.
The centrifuge separates anticoagulated whole blood into plasma
and red cells. The plasma pump pulls the plasma from the
separation chamber into the plasma container, while the heavier
cellular components are pushed out of the separation chamber into
the red cell container.
Typical Main Collection Screen – Draw
During the draw phase, the default or operator-set return rate is
displayed in the return rate button. When the draw phase is complete,
the procedure automatically advances to a return phase.
Note: Refer to Chapter 3, Intelligent Flow Control, IFC
Monitoring, for more information on monitoring the donor flow
rate.
