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 per-
spective clamp finger-type sensor.
Then measured signal can be obtained by a photosensi-
tive element, information acquired through which will be
shown on screen through treatment in electronic circuits
and microprocessor.
