Abstract: A vital sign measurement device includes a sensor fixation device, an optical sensing system, and an output unit. The sensor fixation device is adapted to be placed against an anatomical location of a subject, within which is an artery. The optical sensing system includes an optical source, an optical refractor, and an optical detector, all of which are held by the sensor fixation device and move with movement of the sensor fixation device. The optical sensing system is positioned with respect to the sensor fixation device to sense movement corresponding to an arterial pulse when the sensor fixation device is placed against the anatomical location of the subject. The optical sensing system can sense an arterial pulse from the movement, bending, or compression of at least one portion of the optical sensing system relative to other portions of the optical sensing system resulting in a change in an optical signal received by the optical detector.

The sensor fixation device is adapted to be placed against an anatomical location of a subject, within which is an artery. The optical sensing system includes an optical source device and an optical detector, both of which are held by the sensor fixation device and move with movement of the sensor fixation device. The optical source device is configured to produce a speckle pattern output. The optical detector is positioned to detect at least a portion of the speckle pattern output and generate therefrom the detected portion of the speckle pattern output. The optical sensing system can sense an arterial pulse from the movement, bending, or compression of at least one portion of the optical sensing system relative to other portions of the optical sensing system resulting in a change in the optical signal received within the detected portion of the speckle pattern output.

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.
