The problem of overrating would emerge when the patient is suffering from toxicosis which
is caused by carbon monoxide, the device is not recommended to be used under this
circumstance.
2.3 Environment Requirements
Storage Environment
a) Temperature: -40 ~+60
b) Relative humidity: ≤95%
c) Atmospheric pressure: 500hPa~1060hPa
Operating Environment
a) Temperature: 10 ~40
b) Relative Humidity: ≤75%
c) Atmospheric pressure: 700hPa~1060hPa
3 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
2
) 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
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.
