Patent number: 8644901Abstract: A system and method for non-invasively estimating the tissue blood oxygen saturation level of a human subject, including so-called “outliers”, whose physiological make-up causes previously-known techniques to generate invalid tissue blood oxygen saturation estimations. The system includes a computing device and a sensor. The sensor includes a light source configured to emit light of at least four different wavelengths, one at a time. The sensor also includes two light detectors, each positioned a different distances from the light source. Optical density measurements are taken by the light detectors and provided to the computing device. A first tissue blood oxygen saturation value is computed using the optical density measurements associated with three of the four wavelengths, and a second tissue blood oxygen saturation value is computed using the optical density measurements associated with four of the wavelengths.Type: GrantFiled: February 23, 2011Date of Patent: February 4, 2014Assignee: Covidien LPInventors: Ronald A. Widman, Arik Anderson, Oleg Gonopolskiy

Publication number: 20140012107Abstract: An exemplary sensor includes a sensor pad defining a plurality of openings and a circuit board. The circuit board is at least partially disposed in the sensor pad and has a light source configured to generate near-infrared light and a light detector configured to receive near-infrared light. The light source and the light detector are each aligned with one of the openings of the sensor pad so that near-infrared light generated by the light source can travel through a part of a patient's body to the light detector and the near-infrared light received by the light detector indicates oxygen saturation of the part of the patient's body through which the light travelled. The circuit board further includes an integrally formed tail at least partially disposed in the sensor pad. Additionally, the sensor pad includes an overlay disposed on the tail.Type: ApplicationFiled: September 11, 2013Publication date: January 9, 2014Applicant: Covidien LPInventors: Oleg Gonopolskiy, Melissa Muto, Matthew Stimpson, Richard Morabito
