2 DESCRIPTION OF COMBILYZER Plus
The
COMBILYZER Plus
is
designed for urine test strip reading.
The instrument includes two main
functional units:
-
portable, battery-operated
Reader Unit for urine analysis
-
bench-top, AC-powered Printer
Station, which docks with the
portable Reader Unit and
produces printed reports.
Figure 2. The Reader Unit
The Reader is menu-driven, so
the operator needs to set up the
Reader Unit first according to the
operational conditions with the
help of the function menus. After
placing the moistened urine strip
on the strip holder the instrument
reads and evaluates the strips
automatically.
The urine test strip containing chemical reagents is positioned under the reader's
sensor. After the pads' colours have been evaluated, the strip should be
discarded by the operator. The testing corresponds with the reaction time of the
chemical reagents - about 60 seconds.
The COMBILYZER Plus
works using the reflectance photometry method: inside
the reader, the strip is illuminated by white light, and the light reflected from the
strip is detected by a colour CCD sensor. The RGB signals are digitised using
analogue-digital conversion. The digitised image is processed by a built-in
program: it locates the pads and, based on the reflected light, calculates the
results. The results, together with the current date, time and patient ID, are
