Abstract
A wearable pulse oximetry device and associated methods are provided. In some embodiments, the device includes at least two light sources having different wavelengths and at least one detector responsive to the different wavelengths. The device also includes a structure adapted to fixate at a distal end of the wearer's ulna bone at a fixated area. The light sources having different wavelengths and the at least one detector are fixed within, or adjacent to, the structure such that when the structure fixates at the fixated area the light sources and the at least one detector are positioned adjacent to the distal end of the ulna, and the at least one detector is positioned to detect light emitted from the at least two light sources.
