Introduction

Using red light and infrared light to illuminate the finger alternately, the photodiode at the receiving end will generate a weak photocurrent that changes with the pulse. The photocurrent is converted, filtered and amplified to obtain the pulse waveform, and the pulse frequency is obtained according to the distance between the peaks. The ratio of photocurrent to blood oxygen saturation.

In the non-invasive detection using the blood flow volume pulse wave as the direct measurement data, the selection of the spectral measurement site should follow the following principles:

• The blood vessels should be richer, and the proportion of effective information such as hemoglobin and ICG in the spectrum should be increased in the total material information

• It has obvious characteristics of blood flow volume change to effectively collect volume pulse wave signal

• It is not easily affected by external interference, and the tissue characteristics there are less affected by individual differences, so as to obtain a human body spectrum with good repeatability and stability

• It is easy to implement spectral detection and easy for the subject to accept, so as to avoid interference factors such as rapid heart rate and measurement position movement caused by stressful emotions.
