    摘要： An apparatus for evaluating a vascular endothelial function includes: 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, and configured to apply continuous pressure stimulation; 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, pulse waves before and after the continuous pressure stimulation is applied; and an analyzer, configured to evaluate the vascular endothelial function by comparing the pulse waves detected before and after the continuous pressure stimulation is applied.

    摘要： A vessel wall monitoring apparatus includes: a first detecting unit which detects vessel diameter information based on first biological information obtained from a subject; a first producing unit which differentiates the vessel diameter information detected by the first detecting unit, to produce a vessel diameter function; a second detecting unit which detects blood pressure based on second biological information obtained from the subject; a second producing unit which performs a logarithmic operation on the blood pressure detected by the second detecting unit, to produce a logarithmic blood pressure function; and an outputting unit which produces an impedance model expression by using the vessel diameter function, the logarithmic blood pressure function, and mechanical characteristic values including a stiffness, viscosity, and inertia, and which calculates and outputs at least one of the stiffness, the viscosity, and the inertia based on the impedance model expression.
