Abstract
Described herein are various embodiments of a broad spectrum optical device, system and method for monitoring blood-borne chromophores. In one embodiment, a system comprises a broad-spectrum light source to probe multiple blood-borne chromophores associated with a physiological condition; a spectrometer operable to acquire an optical signal resulting from the broad-spectrum illumination; and a digital data processor operable to process the broad-spectrum response to at least partially spectrally resolve respective spectral responses to output a health-related indicator.
Claims86
A system for interfacing with a user body region to monitor a physiological condition, the system comprising:
- a broad-spectrum light source providing broad-spectrum illumination to the user body region within a designated spectral region to probe multiple blood-borne chromophores associated with the physiological condition and exhibiting respective spectral responses within said designated spectral region;
- a spectrometer operable to acquire an optical signal from the user body region resulting from said broad-spectrum illumination so to digitally capture a broad-spectrum response encompassing said respective spectral responses;
- and
- a digital data processor operable to process said broad-spectrum response to at least partially spectrally resolve said respective spectral responses to output a health-related indicator associated with said blood-borne chromophores and representative of the physiological condition.
An oximeter for monitoring a physiological condition, the oximeter comprising:
- a broad-spectrum light source for providing broad-spectrum illumination to a user body region in probing multiple blood-related chromophores exhibiting distinguishable spectral responses;
- and
- a spectrometer operable to acquire an optical signal from said user body region resulting from said broad-spectrum illumination so to digitally capture said distinguishable spectral responses.
An oximetry system for temporally monitoring oxygen levels at a user body region in real time, the system comprising:
- a light source providing illumination to the user body region within a designated spectral region to probe various blood-borne chromophores exhibiting respective spectral responses within said designated spectral region, at least one of said chromophores comprising a blood-oxygenation-related chromophore;
- a spectrometer operable to acquire an optical signal from the user body region resulting from said illumination so to digitally capture a response encompassing said respective spectral responses;
- and
- a digital data processor operable to process said response to automatically resolve a temporally-defined oxygen delivery event at the user body region in real time.
A non-transitory computer-readable medium comprising instructions to be implemented by one or more digital data processors to monitor a physiological condition at a user body region, by:
- activating a broad-spectrum light source providing broad-spectrum illumination within a designated spectral region to the user body region to probe multiple blood-borne chromophores associated with the physiological condition and exhibiting respective spectral responses within said designated spectral region;
- acquiring from a spectrometer an optical signal from the user body region resulting from said broad-spectrum illumination so as to digitally capture a broad-spectrum response encompassing said respective spectral responses;
- and
- processing said broad-spectrum response to at least partially spectrally resolve said respective spectral responses to output a health-related indicator associated with said blood-borne chromophores and representative of the physiological condition.
