Abstract:
1. A vital sign measurement device comprising: a sensor fixation device adapted to be placed against an anatomical location of a subject, within which is an artery; a sensor frame held by the sensor fixation device, an optical sensing system held by the sensor frame and comprising an optical waveguide, an optical source device to supply optical energy to a first end of the optical waveguide, and an optical detector to detect an amount of optical energy exiting the second end of optical waveguide, the optical sensing system adapted to sense an arterial pulse from the compression or flexing of at least a portion of the optical waveguide resulting in reduction of the amount of optical energy exiting the second end of the optical waveguide; and an output unit configured to receive a signal indicative of the amount of light exiting the second end of the optical waveguide and to generate a measure of the vital sign based at least in part on the received signal.
