ABSTRACT:
In an venous distensibility evaluation index measuring apparatus, a pressure adjusting section generates a pressure to supply it to a venous occluding section; in response thereto the venous occluding section starts to press a vein in the upper arm; upon this operation, an electrode section causes a current to flow, while detecting a voltage at that time; an impedance conversion section converts this detected voltage in combination with the supplied current into an impedance; an impedance transition gradient calculating unit determines a gradient of a rate of change in impedance to the elapsed time; a venous distensibility evaluation index determining unit determines a venous age corresponding to said gradient of the rate of change in impedance to the elapsed time as well as a venous sclerosis level corresponding to the venous age based on the relation data stored previously in a storage section; and finally a display section indicates the venous age and the venous sclerosis level.
