18. Use specification
Expected medical instructions
The fingertip pulse oximeter can be used to
measure human haemoglobin saturation and
pulse rate through finger
Expected patient population
-People who need blood oxygen measurement .
Expected use or interaction with body parts
tissue type
Finger
Expected user profile
People who need blood oxygen measurement ,
doctors, etc
Application environment
Avoid electromagnetic interference
Extreme temperature
Avoid pollution and dust
Avoid direct sunlight, etc
Operating principle
Operation principle of the instrument is to
combine Photoelectric Oxyhemoglobin
Inspection Technology with Capacity Pulse
Scanning and Recording Technology, so that
two lights with different wavelength (660nm
glow and 940nm near infrared light) can be
focused onto human nail 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 diodes through process
in electronic circuits and microprocessor.
