The pulse propagation characteristics of an artery was examined at the both ends of a detouring route. This method uses the parallel structure of arteries, and the characteristics are found using a couple of pulse signals measured at two sides of a suppressed point where the blood flow is stopped. Owing to the closeness of measuring points, this method has the merit of easiness of measurement and the similarity of tissue structure between an artery and skin at measuring points. We made a measuring unit which consists of a couple of pulse wave pickups and a suppressor board between them. Considering the fact that a radial artery and an ulnar artery join at a palmer arch, we set the measuring unit at the wrist point of a radial artery. A delay between two pulse waves measured by the unit because of detour through palmer arch was detected. The result of analyzing two pulse waves shows the effect of aging and blood pressure on delay time as conventional PWV method does. Consequently it is possible that this method can be used for simple measurement of artery conditions.
