In recent years, human pulse wave signal detection has been widely used for evaluation of blood vessel systems, respiratory systems, blood circulation systems, and the like, due to the abundance of physiological and pathological information in human pulse waves. Because the pulse signal of the human body is weak, a circuit with stronger anti-interference capability needs to be designed for signal acquisition and processing.

Because the inside certain space that has of blood oxygen measuring equipment's anchor clamps, and because everyone's finger size is different, lead to when measuring at every turn, the position of the finger that the light source shines has difference, and the different positions of finger means that the regional internal skeleton that the light path passed, the composition proportion of muscle is different to influence the parameter of the corresponding relation of light transmission intensity and blood oxygen value. The current measurement method does not generally consider the difference of different positions of the finger, but structurally limits the possibility of the position change of the finger, and uses the average condition as a calculation parameter, so that the accuracy of the measurement result is low.
