For a long time

Chinese medicine has attached great importance to "pulse diagnosis for patients before acupuncture treatment"

which emphasizes the close relationship between pulse diagnosis and acupuncture. Pulse diagnosis information is closely related to acupuncture research and runs through the whole process of diagnosis and treatment. However

the lack of repeatable and quantifiable real-time detection means of pulse diagnosis information has affected the application of pulse diagnosis in acupuncture research. Photo plethysmo graphy(PPG) technology has the advantages of convenient acquisition

low price

non-invasive

easy to use and so on. Under the guidance of TCM diagnosis theory

this paper discussed the principle and characteristics of fingertip volumetric pulse wave

studied its relationship with Cunkou pulse diagnosis

developed a new fingertip blood volumetric pulse wave measuring instrument

explored the acquisition and measurement methods of volumetric pulse wave signal

and proposed the relationship between the measuring instrument and acupuncture research. It can provide basic tools and data analysis and support for acupuncture research.
