General Description

Haemoglobin saturation is percentage of Oxyhemoglobin (HbO
2
) capacity, compounded with oxygen, by all
combinativable haemoglobin (Hb) Oxyhemoglobin (Hbo
2
) capacity in blood. In other words, it is
consistence of Oxyhemoglobin in blood. It is a very important ecological parameter for Respiratory
circulation System. Many respiratory diseases can result in haemoglobin Saturation being lowered in
human blood. Moreover, the following factors can also lead to problems in oxygen supply, so that human
haemoglobin saturation might be reduced: Automatic Organic Regulation Malfunction caused by
Measurement 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 (R Hb) and
Oxyhemoglobin (O
2
Hb) in glow and near-infrared zones. Operation principle of the instrument is
Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse
Scanning and Recording Technology, so that two beams of different wavelength of light (660nm glow and
940nm near infrared light) can be focused onto human nail tip through perspective clamp finger-type

Anesthesia, intensive Postoperative Trauma, hurts resulted in by some medical examination and etc. In the
situation, illnesses, such as light head, asthenia, vomitory and etc, might happen to patients and even
endanger the patient’s life. Therefore, it is very important to know Hemoglobin saturation of patient timely
in clinical medical aspects. So that doctors can find problems in times.
The fingertip pulse oximeter features in small volume, low power consumption, convenient operation and
being portable. It is only necessary for patient to put one of his fingers into a fingertip photoelectric sensor
for diagnosis, and a display screen will directly show measured value of hemoglobin Saturation. It has been
proved in clinical experiments that it features in rather high precise and repeatability.
