2.2 Major applications and scope of application

The Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through
finger. The product is suitable for being used in family, hospital, oxygen bar, community healthcare,
physical care in sports (It can be used before or after doing sports, and it is not recommended to use
the device during the process of having sport) and etc.
The problem of overrating would emerge when the patient is suffering from toxicosis
which caused by carbon monoxide, the device is not recommended to be used under this circu
mstance.

2.3 Environment requirements

Storage Environment
a) Temperature :-40 ～ +60
b) Relative humidity :5% ～ 95%
c) Atmospheric pressure :500hPa ～ 1060hPa
Operating Environment
a) Temperature:10 ～ 40
b) Relative Humidity :30% ～ 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
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.
