  • Method and apparatus for non-invasive photometric blood constituent diagnosis
    Patent number: 11583212
    Abstract: A non-invasive method and apparatus utilizing a single wavelength (800 nm, isobestic) for the instantaneous, reflective, non-pulsatile spatially resolved reflectance system, apparatus and mathematics that allows for the correct determination of critical photo-optical parameters in vivo. Transcutaneous blood constituent (analyte or drug level) measurements can be determined in real-time. The “closed-form” nature of the mathematics with inclusion of other wavelengths (660 nm and 1300 nm) and a non-invasive transmissive array allows for immediate calculation and real-time display of Hematocrit, Hemoglobin, fractional tissue blood volume (Xb), Hematocrit-Independent Oxygen Saturation, fractional tissue water content (Xw) and other pertinent blood/plasma values in a variety of handheld or other like devices.
