Principle of the Oximeter is as follows: a mathematical formula is established
making use of Lambert Beer Law according to Spectrum Absorption
Characteristics of Reductive hemoglobin(RHb) and Oxyhemoglobin (HbO2)
in glow and near-infrared zones. Operation principle of the instrument:
Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance
with Capacity Pulse Scanning and Recording Technology, so that two beams
of different wavelength of lights (660nm glow and 940nm near infrared light)
can be focused onto a human nail tip through a clamping finger-type sensor. A
measured signal obtained by a photosensitive element, will be shown on the
Oximeter's screen through electronic circuits and a microprocessor.
