Abstract

A pulsewave velocity detection device provides a photodiode capable of detecting light transmission between 600-700 nm and 880-940 nm and a light emitting diode capable of transmitting the same. An optical isolation spacer separates the photodiode and the LED. A main control chip provides processing of collected pulsewave velocity signal detection by measuring with the photodetector. A microcontroller thereby calculates local metabolic rate, blood flow volume, Hb concentration, oxygen saturation, and corrected blood glucose and correlates a corrected blood glucose value to the calculated local metabolic rate, blood flow volume, Hb concentration, and oxygen saturation. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
