Publication number: 20150018651Abstract: A near-infrared spectrophotometric system (e.g., a cerebral oximeter) includes a sensor portion and a monitor portion. The monitor portion includes a processor that runs an algorithm which utilizes the amount of detected light to determine the value of the oxygen concentration (e.g., the absolute level of oxygen concentration). The monitor portion also includes a visual display that displays the determined oxygen concentration values in various formats. The monitor portion may also include an audible device (e.g., a speaker), that provides audible indications of the determined oxygen concentration values. Various visual indicators may include, for example, color-coded graphs of the determined oxygenation values to alert the system user, for example, whether one hemisphere of the brain, or one or more regions of the brain, is in danger of adverse and potentially permanent damage. Also, data may be pre-processed by selecting the most clinically concerning sensor value (e.g.Type: ApplicationFiled: June 23, 2014Publication date: January 15, 2015Inventors: Paul Benni, Bo Chen, Andrew Kersey

Patent number: 8077312Abstract: A method and apparatus for calibrating an NIRS system which includes a sensor portion and for evaluating an NIRS system for proper functioning is provided that includes an enclosure with at least two windows disposed in a wall of the enclosure. The windows allow the light source and one or more detectors of an NIRS system sensor to interface with the enclosure. One window is dedicated to the light source while each light detector has a window dedicated thereto. Thus, the enclosure includes a number of windows equal to the number of light detectors in the NIRS system sensor plus one. The inner surface of the wall(s) of the enclosure is of a light-absorbing color; e.g., black. A diffuse reflectance member of a light-reflecting color, e.g., white, is disposed in the enclosure spaced apart from the surface with the windows disposed therein.Type: GrantFiled: November 3, 2006Date of Patent: December 13, 2011Assignee: CAS Medical Systems, Inc.Inventors: Paul B.
