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 Characteristic s of Reductive
Hemoglobin ( Hb ) and Oxyhemoglobin ( Hb O
2
) in glow & near-infrared zones. Operation principle of
the device is: Photoelectric O xyhemoglobin I nspection T echnology 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 per spective 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 microprocessor.
