2. OVERVIEW

The pulse oxygen saturation is the percentage of HbO
concentration in the blood. It is an important bio-parameter for the respiration. A number of diseases
relating to respiratory system may cause the decrease of SpO
causes such as the malfunction of human body's self-adjustment, damages during surgery, and the
injuries caused by some medical checkup would also lead to the difficulty of oxygen supply in human
body, and the corresponding symptoms would appear as a consequence, such as vertigo, impotence,
vomit etc. Serious symptoms might bring danger to human's life. Therefore, prompt information of pa-
tients' SpO is of great help for the doctor to discover the potential danger, and is of great importance
2
in the clinical medical field.
The Pulse Oximeter features in small volume, convenient operation and being portable. It is only nec-
essary 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.

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 circum-
stance.

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 (HbO
electric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scan-
ning & 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.
