Processing
If power is lost to the machine and residual blood/bone marrow is in the variable
volume separation chamber, follow these steps to safely remove the Angel
®
cPRP Processing Set from the machine:
1. Do not remove the pump loop tubing from the pump rotor until the handle on
the valve assembly is pointed toward the whole blood compartment port.
If required, manually turn the handle on the valve assembly to the whole
blood compartment port (see Figure 3-21).
2. Remove pump loop tubing from the pump rotor to release fluid pressure
on the variable volume separation chamber, which will allow the residual
blood/bone marrow to flow to the whole blood compartment of the three-
compartment reservoir bag.
3. After the blood or mixture of blood and bone marrow has emptied from the
variable volume separation chamber into the whole blood compartment,
remove the disposables from the machine (see Step 5 on Page 3-4).
