Patent number: 9931078Abstract: A sensor includes a sensor pad configured to be disposed on a portion of a patient's body. A light sheet is disposed on the sensor pad and has a first substrate and a second substrate spaced from one another. The light sheet further includes a light source configured to emit near-infrared light and a light detector configured to detect near-infrared light. The light source and the light detector are disposed between the substrates. The sensor pad is configured to allow light generated by the light source to travel through the portion of the patient's body to the light detector. The light received by the light detector is indicative of oxygen saturation of the portion of the patient's body through which the light travelled.Type: GrantFiled: July 8, 2010Date of Patent: April 3, 2018Assignee: COVIDIEN LPInventors: Oleg Gonopolskiy, Arik Anderson

Patent number: 9404961Abstract: A physiological sensor includes a light source and an age detector circuit in communication with the light source. The age detector circuit is configured to determine an age of the light source based on current-voltage characteristics of said light source. In addition, a method includes measuring an initial I-V characteristic and an actual I-V characteristic of the light source, and comparing the initial I-V characteristic to the actual I-V characteristic since changes in the I-V characteristics indicate aging. Actual I-V characteristics can be compared between light sources when they age at different rates to determine light source aging. Moreover, the method may include updating the memory device with the actual I-V characteristic at predetermined times.Type: GrantFiled: December 9, 2008Date of Patent: August 2, 2016Assignee: Covidien LPInventors: Oleg Gonopolskiy, Arik Anderson, Bruce J.

Patent number: 9339240Abstract: 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: January 8, 2014Date of Patent: May 17, 2016Assignee: Covidien LPInventors: Ronald A. Widman, Arik Anderson, Oleg Gonopolskiy

Patent number: 9002425Abstract: An exemplary sensor includes a sensor pad defining a perimeter, a light source, a light detector, and an adhesive layer. The light source is configured to generate near-infrared light and transmit the near-infrared light through part of a patient's body. The light detector is configured to receive the near-infrared light generated by the light source after it has traveled through part of the patient's body. The light received by the light detector indicates an amount of oxygen in the part of the patient's body through which the near-infrared light traveled. The adhesive layer is offset relative to the sensor pad to, for example, allow a clinician to easily remove the sensor from the patient.Type: GrantFiled: April 18, 2014Date of Patent: April 7, 2015Assignee: Covidien LPInventors: Oleg Gonopolskiy, Arik Anderson, Melissa Muto, Matthew Stimpson, Richard Morabito
