Pulse rate measuring method and ring type pulse rate measuring meter

Abstract

The invention relates to a pulse rate measuring method and a ring type pulse rate measuring meter by adopting the method. In the method, a finger pulp is taken as the position for measuring a pulse signal, beam with specific wavelength is radiated to the skin surface of the finger pulp, a transmission and / or transmitted ray intensity signal is adopted through a photoelectric receiver, and the pulse rate can be calculated according to the alternating component of the intensity signal varying in pulse cycles. The ring type pulse rate measuring meter comprises a pulse wave collecting device and a pulse wave processing and displaying device, wherein a central control and signal processing module is arranged in the pulse wave processing and displaying device; and a control signal end of the central control and signal processing module is connected with the pulse wave collecting device in a wired or wireless mode. The ring type pulse rate measuring meter has the characteristics of simple structure, smart appearance and strong interference resistance, is convenient to wear, and can meet the wearing requirement of people in daily life health-care and daily exercise.

Description

technical field [0001] The invention relates to a pulse rate measuring method and a pulse rate measuring instrument adopting the method, in particular to a photoelectric device for non-invasively acquiring fingertip arterial pulse rate, which belongs to the field of medical technology. Background technique [0002] Photoplethysmography scanning method is a conventional method to obtain photoplethysmography, which is a non-invasive detection method for detecting changes in blood volume in living tissue by means of photoelectric technology. When a beam of light of a specific wavelength is used to irradiate the surface of the human fingertip skin and is transmitted to the photoelectric receiver in the form of transmission or reflection, due to the absorption of fingertip skin, muscle and blood, the incident light detected by the detector is Light intensity will be attenuated. Among them, the absorption of incident light by skin, muscle and other tissues remains constant, and t...
