System Description Chapter 1
•
The quick adjust levers which are located on either side of the tube
retainer. The levers are used to raise or lower the tube retainer in
order to securely hold the collection tube in the proper position
•
The interlock switch located in the tube retainer prevents activation
of the closed sampler until a collection tube is inserted properly
•
A needle that pierces the collection tube stopper, vents vacuum or
pressure from inside the tube, aspirates the whole blood and is
retracted and rinsed at the end of each closed sampler cycle
Flow Panel
major components of the flow panel
functional description of each component follows.
Sample Aspiration Peristaltic Pump
The sample aspiration peristaltic pump is composed of a rotor and pump
tube holder. It aspirates whole blood from either an open or closed
collection tube into the shear valve. The pump action is controlled by the
touch plate and an optical detector.
Shear Valve Assembly
The three-piece ceramic shear valve isolates a precise volume of whole
blood by means of a shearing action as the front and rear sections rotate.
The aspirated blood is isolated in three separate segments — one for the
WBC dilution, one for the HGB dilution and one for the RBC/PLT
dilution.
Wash Block
The wash block rinses the outside of the open sample aspiration probe
with Diluent. It air dries the probe and routes the external and internal
rinses to the waste chamber.
Syringe Assembly
The syringe assembly contains a set of five syringes. The two HGB
syringes are operated by the same stepper motor. The RBC Diluent,
WBC Sheath, and WBC Metering Syringes are each operated by a
separate stepper motor.
•
RBC Diluent syringe — delivers a specific volume of Diluent to
transport the blood from the shear valve to the mixing chamber in
the RBC/PLT transducer
