ppg device and process for operating a ppg device

摘要

the invention is based on a ppg device (100) for photoelectric registration of volumenpulsationen of perfused body (1000) with a light source (10).a light sensor (20) and a processing unit (110).the essence of the invention consists inthe ppg device (100), a temperature sensor (200) for measuring a body temperature (210) of the body (1000) system and the processing unit (110) is established.with the help of the body (210), a durchblutungszustand body to determine.the invention also relates to a process for operating a ppg device (100) of a body (1000) of a user for determining a pulse rate.
