Measurement Device and Method for Measuring Psychology Stress Index and Blood Pressure

A measurement device for measuring psychology stress index and blood pressure, wherein the measurement device comprises a micro-processor unit, a display output unit, a button input unit, a pressurizing motor unit, a pressure sensing unit, an airbag unit, and a quick exhaust valve unit, wherein the micro-processor unit is entered into a psychology stress measurement mode according to an operation of the button input unit, wherein while the micro-processor unit controls the pressurizing motor to pressurize the airbag unit with a variable speed, the micro-processor unit measures a pressure signal of the pressure sensing unit, wherein when the pressure signal is determined as a pulse signal, the micro-processor unit controls the pressurizing motor unit to stop pressurizing and measures the pulse signal to calculate a psychology stress index, and the display output unit outputs the psychology stress index.
