Fingertip SpO2 sensor

In clinical practice, functional saturation is often used to reflect the changes of oxygen content in blood. Basic studies have shown that oxygenated hemoglobin and non-oxygenated hemoglobin have different absorption rates to incident light of different wavelengths.The measurement of non-invasive blood oxygen saturation is based on the principle that the amount of light absorbed by the arterial blood changes with the pulse of the artery.Main structure: light emitting device, receiving device and other components. Product Features Oxygen Saturation Probe Finger Clip is made of instrument end connectors. The sensor adopts imported high-precision sensor. Cables used for high-strength bi-alloy special medical cables. This design is used to estimate the oxygen saturation level in the finger using two LEDs. The reflected light from each of the LEDs is absorbed by a photodiode, which converts the current into a digital value. The shape of the finger clip makes the application on the finger user-friendly, and the use of the sensor does not require any additional accessories. The various intensities of the LED can be controlled to realize the location-specific light intensity configuration of the sensor.
