    Abstract: A replaceable cuvette assembly for use in an optical absorbance measurement system for measuring whole-blood hemoglobin parameters or whole-blood bilirubin parameters. The replaceable cuvette assembly includes a cuvette substrate and a cuvette module fixedly connected to the cuvette substrate wherein the cuvette substrate is a support for securing the cuvette assembly within the optical absorbance measurement system. The cuvette module has a sample inlet port, a sample outlet port, an electronic chip assembly, a sample receiving chamber that fluidly communicates with the sample inlet port and the sample outlet port, a first cuvette window, and a second cuvette window forming a portion of the sample receiving chamber. The first cuvette window and the second cuvette window are aligned with each other defining a cuvette optical path length between the first cuvette window and the second cuvette window and disposed within an optical path of the optical absorbance measurement system.

    Abstract: A wearable device includes a measurement device having light emitting diodes (LEDs) measuring a physiological parameter. The measurement device modulates the LEDs to generate an optical beam having a near-infrared wavelength between 700-2500 nanometers. Lenses receive and deliver the optical beam to tissue, which reflects the optical beam to a receiver having spatially separated detectors coupled to analog-to-digital converters configured to generate receiver outputs. The receiver captures light while the LEDs are off, and reflected light from the tissue while the LEDs are on, to generate first and second signals, respectively. Signal-to-noise ratio is improved by differencing the first and second signals and by differencing the receiver outputs. The measurement device further improves signal-to-noise ratio of the reflected optical beam by increasing light intensity of the LEDs relative to an initial light intensity. The measurement device generates an output signal representing a non-invasive measurement on blood contained within the tissue.
