Patent ID: 8827911

Claim:
An apparatus for evaluating a vascular endothelial function, the apparatus comprising: a cuff, to be wound around a part of a body of a subject; a cuff pressure controller, configured to control a pressure of the cuff during a first pressurization period in which the cuff is pressurized and depressurized for performing first blood pressure measurement, configured to control the pressure of the cuff and apply continuous pressure stimulation during a continuous pressure stimulation period, and configured to control the pressure of the cuff during a second pressurization period in which the cuff is pressurized and depressurized for performing second blood pressure measurement; a cuff pressure detector, configured to detect the pressure of the cuff from output of a pressure sensor connected to the cuff; a pulse wave detector, configured to detect, from the output of the pressure sensor, first pulse waves during the first pressurization period before the continuous pressure stimulation during the continuous pressure stimulation period is applied and second pulse waves during the second pressurization period after the continuous pressure stimulation during the continuous pressure stimulation is applied; and an analyzer, configured to evaluate the vascular endothelial function by comparing the first pulse waves and the second pulse waves.
