A novel PPG pulse diagnosis instrument which can be used to assist the application of acupuncture and moxibustion

Abstract

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.
