2. Principle
Figure 1 Operating 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 (HbO2) in glow & near-infrared zones. Operation principle
of 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 the 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.
3. Functions
A. SpO2 value display
B. Pulse rate value display, bar graph display
C. Low battery indication: low-battery indication appears when the battery
voltage is too low to work.
D. Automatic standby function
