Abstract

A physiological parameter monitoring device has a physiological parameter detector and an analyzer. The physiological parameter detector has a wrist belt, a pulse sensor mounted to an inner side of the wrist belt to output a pulse sensing signal and an analog to digital converter. The pulse sensor has a soft bag used to press wrist artery and a pressure sensor connected to the soft bag to detect an inner pressure change according to the wrist artery and then output the pulse sensing signal. The analog to digital converter is electronically connected to the pressure sensor to converter the pulse sensing signal to digital signal. The analyzer links to the physiological parameter to determine a health condition according to the digital signal of the pulse sensing signal.
