The Angel
®
cPRP Processing Set consists of a pre-connected variable volume
separation chamber, a tubing set with a platelet sensor/valve assembly, and
a three-compartment reservoir bag for the collection of blood products (whole
blood, red blood cells, and platelet poor plasma). The Angel
®
cPRP Processing
Set also contains a 20 ml luer lock syringe for the collection of platelet rich
plasma (PRP), two 60 ml specimen cups for use in a sterile field, a whole
blood bag spike adapter, male-female luer plugs, and labels for collected blood
components.
Major Components
(see Figure 2-1)
Variable Volume Separation Chamber: The Angel
®
cPRP Processing Set
utilizes a variable volume separation chamber that can process from 40 ml
– 180 ml of anticoagulated autologous whole blood or mixture of blood and
bone marrow in a single cycle. The Angel
®
cPRP Processing Set is capable of
processing up to three (3) cycles per disposable.
The top half of the variable volume separation chamber (the hard plastic
component) is the separation chamber plate. The separation chamber plate is
used to seat the variable volume separation chamber in the centrifuge.
Platelet Cuvette/Valve Assembly: The platelet cuvette/valve assembly contains
three major components: (1) the platelet cuvette, (2) the pump loop tubing and
(3) the rotating valve. The platelet cuvette is seated in the platelet sensor and is
used to optimize the collection of the separated blood components. The pump
loop tubing is inserted around the pump, which moves volume from the whole
blood compartment of the three-compartment reservoir bag to the variable volume
separation chamber and from the variable volume separation chamber to the
various collection compartments for the separated blood products (PRP, PPP and
RBC). The rotating valve rotates throughout the course of the processing cycle
to direct the whole blood, the mixture of blood and bone marrow, or its separated
components through the appropriate pathway.
The platelet cuvette/valve assembly has been designed so that the operator can
easily install the platelet cuvette/valve assembly while insuring that the platelet
cuvette is properly seated in the platelet sensor and that the rotating valve is
properly seated on the valve assembly driver.
