Ear sensor
First Claim
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, and the detector disposed in the detector housing; and
a cup extending from the detector housing, wherein the cup generally conforms to the curvature of a concha site.

Abstract
An ear sensor provides a sensor body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The sensor body is flexed so as to position the housing over a concha site. The sensor body is unflexed so as to attach the housing to the concha site and position the optical assembly to illuminate the concha site. The optical assembly is configured to transmit optical radiation into concha site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.

9. An ear sensor method comprising:
-
providing a sensor body having a base, legs extending from the base and an optical housing disposed at ends of the legs distal the base; disposing an optical assembly in the housing; providing an ear surface conforming member coupled to at least a portion of the housing so as to physically couple the housing to a concha site and block ambient light from the optical assembly accordingly, the ear surface conforming member having a cup shape. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An ear sensor comprising:
-
a clip means for clipping on a concha site, the clip means having a flexed position and an unflexed position; an optical means for transmitting multiple wavelength light into a tissue site when activated and for receiving the light after attenuation by pulsatile blood flow within the tissue site, the optical means disposed on the clip means so that the optical means can be positioned on the concha site in the flexed position and pinched against the concha site in the unflexed position; a cup means for physically coupling at least a portion of the optical means to the concha site and for blocking ambient light from the optical means; a connector means for mechanically attaching to and electrically communicating with a monitor; and a cable means for interconnecting the connector means with the optical means. - View Dependent Claims (18, 19, 20, 21, 22)
