Abstract
A blood rheology measurement device and a blood rheology measurement method which detect a fingerprint or a vein to thereby measure a positional relation between an artery in a living body and a sensor on the same conditions for each subject during non-invasive measurement and which correctly evaluate a change of blood rheology with elapse of time. A vein pattern or a fingerprint pattern peculiar to a subject is detected, recognized, and stored, a position of a sensor is adjusted so that the detected vein pattern or fingerprint pattern agrees with the stored vein pattern or fingerprint pattern every measurement, and a blood rheology index value indicating blood fluidity (fluidity/viscosity) is measured.
