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
of the instrument is: Photoelectric Oxyhemoglobin Inspection Technology is
adopted in accordance with Capacity Pulse Scanning & Recording Technology,
so that two beams of different wave length 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.
