Abstract

A vital sign measurement device includes an occluding device, a motion sensor, and an output unit. The occluding device is adapted to be placed against an anatomical location of a subject, within which is an artery, and to apply a pressure to the anatomical location of the subject to occlude the artery. The motion sensor is positioned with respect to the occluding device to sense movement corresponding to an arterial pulse when the occluding device occludes the anatomical location of the subject. The motion sensor includes a sensor pad positioned for placement against an anatomical location of a subject and to move in response to an arterial pulse. The output unit receives, from the motion sensor, an input indicative of the amount of movement of the sensor pad and generates, using the input, a measure of the vital sign.
