1. A physiological sensor configured to measure an indication of a physiological characteristic of a living patient, the physiological sensor comprising:

a plurality of light emitting sources arranged to impinge light on body tissue of a living patient including at least eight light emitting sources, each of the at least eight light emitting sources emitting light at a different wavelength,wherein at least a subset of the plurality of light emitting sources are further arranged in two or more clusters, each cluster comprising at least two light emitting sources that emit light within a wavelength range that is different from and does not overlap with the wavelength range of the at least two light emitting sources of other clusters,wherein for each cluster, light emitting sources that emit light at proximate wavelengths are adjacent to each other,wherein each light emitting source is activated by addressing at least one of a plurality of rows and at least one of a plurality of columns of an electrical grid and the plurality of light emitting sources are arranged to minimize optical pathlength differences;

a detector responsive to transmitted light after attenuation by body tissue of the living patient, the body tissue including pulsating blood, wherein the detector is configured to generate a signal indicative of a physiological characteristic of the living patient; and

a sensor housing configured to position the plurality of light emitting sources and the detector with respect to the body tissue of the living patient.

Abstract

A physiological sensor is adapted to removably attach an emitter assembly and a detector assembly to a fingertip. The emitter assembly is adapted to transmit optical radiation having multiple wavelengths into fingertip tissue. The detector assembly is adapted to receive the optical radiation after attenuation by the fingertip tissue. The sensor has a first shell and a second shell hinged to the first shell. A spring is disposed between the shells and urges the shells together. An emitter pad is fixedly attached to the first shell and configured to retain the emitter assembly. A detector pad is fixedly attached to the second shell and configured to retain the detector assembly. A detector aperture is defined within the detector pad and adapted to pass optical radiation to the detector assembly. A contour is defined along the detector pad and generally shaped to conform to a fingertip positioned over the detector aperture.
