Principle
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
the device 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 microprocessor.
