The YUWELL® Finger Pulse Oximeter features in small volume, low power
consumption, convenient operation and portable. It is only necessary for patient to
put one of his fingers into a fingertip photoelectric sensor for measurement, and then
the screen will display the measured value of pulse oxygen saturation and pulse rate.
It has been proved in clinical experiments that it features in rather high precise and
repeatability.
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 deoxyhaemoglobin(HHb)
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 (red light and 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 display through process in electronic circuits and
microprocessor.
