1. An ear sensor for optically measuring physiological parameters related to blood constituents by transmitting multiple wavelengths of light into a concha site and receiving the light after attenuation by pulsatile blood flow within the concha site, the ear sensor comprising a sensor body, a sensor connector and a sensor cable interconnecting the sensor body and the sensor connector, the sensor body comprising:

  • a base;

    a first leg extending from the base to a detector housing;

    a second leg extending from the base to an emitter housing;

    an optical assembly having an emitter and a detector;

    the emitter disposed in the emitter housing;

    the detector disposed in the detector housing;

    the legs having an unflexed position with the emitter housing proximate the detector housing and a flexed position with the emitter housing distal the detector housing;

    the legs moved to the flexed position so as to position the detector housing and emitter housing over opposite sides of a concha site; and

    the legs released to the unflexed position so that the concha site is grasped between the detector housing and emitter housing.
