Abstract

Described herein are apparatus, devices and methods of use to monitor a patient'"'"'s condition. The apparatus includes a housing having an internal volume divided into a first and second cavity by a central opaque partition; a light source positioned within the first cavity and coupled to a first side of the partition; a detector positioned within the second cavity and coupled to a second side of the partition; and a lens material filling the internal volume of the housing and enclosing the first and second cavities. The light source includes a first light emitting diode configured to emit a first wavelength of light and a second light emitting diode configured to emit a second wavelength that is different from the first wavelength of light. The detector is configured to measure at least one of an absorbance, a scattering or a frequency of the first and second wavelengths of light.

Claims

1. An apparatus comprising:

a housing having an internal volume divided into a first and second cavity by a central opaque partition;

a light source positioned within the first cavity of the housing and coupled to a first side of the partition, wherein the light source comprises a first light emitting diode configured to emit a first wavelength of light and a second light emitting diode configured to emit a second wavelength that is different from the first wavelength of light;

a detector positioned within the second cavity of the housing and coupled to a second side of the partition, wherein the detector is configured to measure at least one of an absorbance, a scattering or a frequency of the first and second wavelengths of light; and

a lens material filling the internal volume of the housing and enclosing the first and second cavities.

2. The apparatus of claim 1, wherein the first wavelength of light is between about 660 nanometers to about 735 nanometers and emitted at a first frequency.

3. The apparatus of claim 2, wherein the second wavelength of light is between about 910 nanometers to about 990 nanometers and emitted at a second frequency that is different from the first frequency.

4. The apparatus of claim 1, wherein the lens material comprises an elastomeric lens material.

5. The apparatus of claim 1, wherein the lens material comprises a dielectric lens material.
