  • Publication number: 20100268090
    Abstract: A system and method of non-invasive determination of hematocrit change from optical reflected light in combination with transmitted light or from reflected light measured from one or more locations on a blood carrying medium. Determining the cardiac output of a patient based on the amount of plasma or saline injected and the determined hematocrit change. The cardiac output may be determined on a patient undergoing hemodialysis. The hematocrit changes can be detected transcutaneously, transarterially, intraarterially, or across an extracorporeal arterial circulatory path.

  • Patent number: 6272376
    Abstract: A method of analysis of organic matter, called Time-Resolved, Laser-Induced Fluorescence Spectroscopy (TR-LIFS), characterizes and discriminates certain matter, such as tissue, by investigating the fluoresence response of the protein and lipid fluorophore components in both the spectral domain and time domain. This method is more robust than prior methods as (1) can investigate the matter at muplitple wavelengths and even across an entire spectrum and (2) is more sensitive to picking up weaker fluorescence signals such as that from lipids. A detailed study of the use of TR-LIFs for the charaterization of arterial wall tisse is described. A system and instrumentation for practicing the novel method is also disclosed.

  • Patent number: 5701902
    Abstract: A burn evaluation apparatus and related method, that allows a surgeon to make a quick evaluation of the extent and depth of a skin burn injury by employing induced ultraviolet or blue light fluorescence spectroscopy and visible and infrared reflectance spectroscopy. The apparatus monitors the condition of the structural and metabolic constituents in the injured skin. The apparatus includes a plurality of light sources, a sensor, a microprocessor, and several optical fiber bundles. The light sources emit excitation light at predetermined wavelengths, and when each is activated, the sensor measures the amount return light received within several wavelength bands of interest. A side fiber bundle spaced about a centimeter from a main fiber bundle assists in detecting tissue water below the burn area.
