1. A disposable component of a noninvasive optical sensor, the disposable component comprising:

  • a first clip configured to mate with a casing housing at least one energy emitter operable to emit light at multiple wavelengths, the first clip having a first opening to allow the light to pass from the energy emitter through the first opening to a measurement site;

    a second clip configured to mate with a second casing housing a detector capable of detecting the light after attenuation by body tissue at the measurement site, the second clip having a second opening to allow the light to pass from the measurement site through the second opening to the detector, each of the first clip and the second clip comprising a base and at least one vertical element extending perpendicularly to the base;

    a flexible base operably positioning the first clip and the second clip and configured to be applied around the measurement site, the base comprising;

    an adhesive capable of removably adhering to the measurement site,a flexible base tape layer,an opaque tape layer positioned on the base tape layer, the base of each of the first clip and the second clip positioned on the opaque tape layer, the opaque tape layer comprising a first window aligned with the first opening of the first clip and a second window aligned with the second opening of the second clip,a light blocking layer configured to substantially prevent ambient light from reaching the measurement site and positioned over the opaque tape layer, anda face tape layer positioned above the light blocking layer, the face tape layer comprising a plurality of protrusions extending beyond the base tape and sized to wrap around the measurement site; and

    a polyester film layer configured to hold each of the first clip and the second clip in place and positioned between the opaque tape layer and the light blocking layer, the polyester film layer comprising a plurality of slots, the at least one vertical element of each of the first clip and the second clip extending through one of the plurality of slots with the polyester film layer resting against the base of each of the first clip and the second clip.
