3. Principle and Caution

3.1 Principle of measurement

Principle of the Oximeter is as follows: An experience
formula of data process is established taking use of
Lambert Beer Law according to Spectrum Absorption
Characteristics of Reductive Hemoglobin (Hb) and
Oxyhemoglobin (HbO
Operation principle of the instrument is: Photoelectric
Oxyhemoglobin Inspection Technology is adopted in
accordance with Capacity Pulse Scanning & Recording
Technology, so that two beams of different wavelength
of lights can be focused onto human nail tip through
perspective clamp finger-type sensor. Then measured
signal can be obtained by a photosensitive element,
information acquired through which will be shown on
screen through treatment in electronic circuits and
) in glow & near-infrared zones.
