6.1 Product Operation Scope
This Pulse Oximeter is a kind of innovated detection device with non-invasive and continuous features for artery SpO2 and
PR detection. It is portable and easy to measure the SpO2 and PR value quickly and precisely. This can be through the
finger Pulse Oximeter to meas Oxygen Saturation and Heart Rate.
This product is suitable for family, clinic, oxygen bar, sports health (use before and after excercise, it is not recommended
to use during exercise), community health and other areas. Suitable age group is 15 to 60 years.
6.2 General Description
Hemoglobin Saturation is percentage of Oxyhemoglobin (HbO2) capacity compounded with oxygen, by all combinative
Hemoglobin (Hb) Oxygen (HbO2) 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
hemoglobin saturation might be reduced: such as Automatic Organic Regulation Malfunction caused by Anesthesia,
Intensive Postoperative Trauma, Hurts resulted by some medical examination etc. In the situation, illness, such as light
head, asthenia, vomitory etc., might happen to users and even endanger the user’s life. Therefore, it is very important to
know Hemoglobin Saturation of users timely in clinical medical aspects so that doctors can find problems in time. It is
only necessary for users 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.
6.3 Measurement Principle
Principle of the Oximeter is as follows: An experience formula of data process is established taking use of Beer-Lambert
law according to Spectrum Absorption Characteristics of reductive Hemoglobin (R Hb) and Oxyhemoglobin (O2Hb) in
glow and near-infrared zones. Operation principle of the instrument is photoelectric Oxyhemoglobin Inspection
Technology adopted in accordance with Capacity Pulse Scanning and Recording Technology, so that two beams of
different wavelength of lights (600nm glow and 940nm near-infrared light) 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 two groups of LED through process in electronic circuits and microprocessor.
