Multi-stream data collection system for noninvasive measurement of blood constituents
First Claim
1. A noninvasive optical physiological measurement device adapted to be worn by a wearer, the noninvasive optical physiological measurement device providing an indication of a physiological parameter of the wearer, the noninvasive optical physiological measurement device comprising:
- one or more light emitters;
a substrate having a surface;
a wall extending from the surface;
at least four detectors arranged on the surface and spaced apart from each other, at least one of the at least four detectors configured to output data or one or more signals responsive to light from at least one of the one or more light emitters attenuated by body tissue, the data or one or more signals including information sufficient to determine a physiological parameter of the wearer; and
a cover arranged to cover at least a portion of the surface of the substrate, the cover comprising a protrusion that extends over all of the at least four detectors arranged on the surface of the substrate, at least part of the cover being light permeable.

Abstract
The present disclosure relates to noninvasive methods, devices, and systems for measuring various blood constituents or analytes, such as glucose. In an embodiment, a light source comprises LEDs and super-luminescent LEDs. The light source emits light at at least wavelengths of about 1610 nm, about 1640 nm, and about 1665 nm. In an embodiment, the detector comprises a plurality of photodetectors arranged in a special geometry comprising one of a substantially linear substantially equal spaced geometry, a substantially linear substantially non-equal spaced geometry, and a substantially grid geometry.
