System Components
Section 1
Tower Cover
The
Tower Cover
on the SL model, although not part of the Sample Loader, has
an Interlock Sensor Switch which prevents the loader from operating if the cover
is not in place. If the cover is removed during operation, the Sample Loader comes
to an immediate halt, causing a fatal fault. This feature provides further safety for
the operator.
Bar Code Reader
The
Bar Code Reader
is an LED type and can accommodate Code 39, Code 128,
CODABAR, and Interleaved 2 of 5 formats. On the SL model, the Bar Code
Reader is located on the Sample Loader. It reads the bar code on the tube when the
tube is at the aspiration station.
Tube Sensor Assembly
The
Tube Sensor Assembly
senses the presence of a sample tube at each Mixing
Station.
Tube Mixer Assembly
The
Mixer Assembly
consists of a double-tube holder directly attached to a
stepper motor. As the rack advances, the tube holder descends and grabs the tube.
The tube holder rotates 15 times in an outward motion of approximately 135
degrees. The double-tube configuration of the tube holder allows each tube to be
held and mixed twice in succession before it passes to the mixing station. An air
cylinder governs the rotation movement of the tube holder.
Closed Sample Aspiration Tower Module
The
Closed Sample Aspiration Tower
is used to aspirate whole blood from a
closed collection tube. It is used when the Closed Sampler mode is selected on
either the SL or CS model. The configuration of the Tower Module differs
depending on the model.
In the CS model, the Tower Module consists of the following components:
• Aspiration/Vent Needle
• Wash Block
• Tube Spinner (includes motor and belt)
• Door Assembly (includes Tube Holder, Bar Code Reader, Swivel Door,
Solenoid, and Interlock Switch).
In the SL model, the Tower Module consists of the following components:
• Aspiration/Vent Needle
• Wash Block
• Tube Spinner (includes motor and belt)
The Door Assembly is eliminated from the Tower, and the Bar Code Reader is
moved to the Sample Loader which also contains the Mixer Assembly.
