Main Performance; Main Parameters - PULOX PO-400 Mode D'emploi

The Pulse Oximeter features in small volume, low power consumption, convenient operation and being
portable. It is only necessary for patients to put one of his fingers into a probe for diagnosis, and a
display screen will directly show the measured value of pulse oxygen saturation with the high veracity
and repetition.
2.1 Features
A. Operation of the product is simple and convenient.
B. The product is small in volume,light in weight and convenient in carrying.
C. Low power consumption
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 circumstance.
2.3 Environment Requirements
Storage Environment
a. Temperature : -40°C~+60°C
b. Relative humidity : ≤95%
c. Atmospheric pressure : 500hPa~1060hPa
Operating Environment
a. Temperature: 10°C~40°C
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 (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 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.
