Abstract
An apparatus and method for pulse detection based on blood pressure measuring stage is disclosed. Both monitoring of blood pressure and blood vessel pulse are integrated and applied to an apparatus. With the components of the blood pressure monitor, such an inflatable cuff, an air pump and a variable flow valve, with a unique sequential pressure control of reduction and regulation of pressure, not only can blood pressure parameters but also pulse signals under various pressures be measured to provide a complete analysis of blood artery/vessel conditions.
