General information
BO-750 is designed to measure %SpO
2
and pulse rate accurately, quickly
and simply at a fingertip using high precision optical components and
sophisticated analogue-digital circuits.
Haemoglobin in blood turns to oxyhaemoglobin in the lungs to carry oxygen
to body cells and turn itself to deoxyhaemoglobin after transferring oxygen
to the body cells and returning to the lungs. These oxyhaemoglobin and
deoxyhaemoglobin are well known to absorb specific wavelength of lights,
infrared and visible red, respectively. BO-750 is calibrated to display
functional oxygen saturation analyzed from pulse wave length detected with
two high-precision light emitting diodes (LED) emitting infrared and visible
red lights individually from one side and a photo diode receiving these lights
passing through fingertip at the other side.
This device is for medical staff use.
