Angel®cPRP System Operator’s Manual1-1
Overview
The Angel®Concentrated Platelet Rich Plasma (cPRP) System (Angel®cPRP
System) consists of a blood processing device and disposable products used for
separation of whole blood or mixture of blood and bone marrow into red cells,
platelet poor plasma, and platelet rich plasma. The processing disposable, the
Angel®Concentrated Platelet Rich Plasma (cPRP) System Processing Set,
is designed for single-patient use. The variable volume separation chamber
allows the clinician to process from 40 ml to 180 ml of autologous whole blood
or mixture of blood and bone marrow in a single cycle. A total of 180 ml can be
processed over three (3) cycles per disposable.
Product Description
The Angel®Concentrated Platelet Rich Plasma (cPRP) System processes a
determined volume of anticoagulated whole blood or mixture of blood and bone
marrow from a patient and separates the blood/bone marrow into its primary
components: red blood cells (RBC), platelet poor plasma (PPP), and platelet rich
plasma (PRP).
The basic steps are:
Blood Collection: The whole blood or mixture of blood and bone marrow is
drawn from a patient and mixed with a citrate anticoagulant. The collected whole
blood/bone marrow is mixed in a 7:1 ratio (7 parts whole blood to 1 part citrate
anticoagulant (ACD-A)).
Processing: The Angel®(cPRP) Processing Set utilizes a variable volume
separation chamber (40 ml – 180 ml) which allows the clinician to determine the
amount of preoperative blood/bone marrow volume to be processed. The Angel®
cPRP Processing Set allows for up to three processing cycles per disposable.
Once the anticoagulated whole blood or mixture of blood and bone marrow has
been dispensed into the whole blood compartment of the three-compartment
reservoir bag, the clinician selects the desired volume of autologous whole
blood/bone marrow they elect to process and presses the “Start” button on the
touch screen display. The Angel®Concentrated Platelet Rich Plasma (cPRP)
System will ll the variable volume disposable with the pre-determined volume of
anticoagulated whole blood or mixture of blood and bone marrow, separate the
whole blood/bone marrow through centrifugation, and collect the primary blood
components (RBC, PPP, and PRP) in their respective collection compartments.
Administration: Reinfusion of blood components is under the control
and supervision of the physician in charge. Follow your institution’s blood
administration protocol for appropriate handling and labeling of blood components.

Installing the Disposables
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 eld, 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.
