Patent number: 8457722Abstract: Devices and methods for measuring body fluid-related metric using spectrophotometry that may be used to facilitate diagnosis and therapeutic interventions aimed at restoring body fluid balance. In one embodiment, the present invention provides a device for measuring a body-tissue water content metric as a fraction of the fat-free tissue content of a patient using optical spectrophotometry. The device includes a probe housing configured to be placed near a tissue location which is being monitored; light emission optics connected to the housing and configured to direct radiation at the tissue location; light detection optics connected to the housing and configured to receive radiation from the tissue location; and a processing device configured to process radiation from the light emission optics and the light detection optics to compute the metric where the metric includes a ratio of the water content of a portion of patient's tissue in relation to the lean or fat-free content of a portion of patient's tissue.Type: GrantFiled: September 30, 2005Date of Patent: June 4, 2013Assignee: Covidien LPInventors: Joseph M.

Patent number: 8449834Abstract: The present disclosure relates to a carbon dioxide detector having a borosilicate substrate. It may also have a carbon dioxide responsive indicator solution disposed on the borosilicate substrate. The carbon dioxide detector may be part of a carbon dioxide detector system also including an air intake operably connected to the housing to allow air to reach the carbon dioxide detector. The carbon dioxide detector may include a borosilicate substrate and a carbon dioxide responsive indicator solution disposed on the borosilicate substrate. This detector may be part of a further system, such as a resuscitation system. The detector may be made by wetting a borosilicate substrate with a carbon dioxide responsive indicator solution and drying the indicator solution to immobilize it and form a dried carbon dioxide detector. It may be used to detect the concentration of carbon dioxide in an air sample by exposing the detector to the sample.Type: GrantFiled: September 25, 2006Date of Patent: May 28, 2013Assignee: Covidien LPInventors: Rafael Ostrowski, Martin Debreczeny

Publication number: 20100076319Abstract: Systems and methods for reducing scattering effects and correcting for patient to patient anatomical variability are provided. The scattering coefficient of an individual patient's tissue may be corrected for by examining the DC light levels of light passing through the tissue. By comparing the intensity of the light leaving the emitter with the light that reaches the detector to generate a DC component of the signal, which is representative of the anatomical structures of a patient, the AC component of the light may be corrected for the scattering coefficient of the tissue. By correcting the AC signal to account for the scattering coefficient of an individual patient's tissue, a medical sensor may be calibrated in situ for every patient.Type: ApplicationFiled: September 25, 2008Publication date: March 25, 2010Applicant: Nellcor Puritan Bennett LLCInventors: Paul Mannheimer, Martin Debreczeny

Publication number: 20090247853Abstract: Spectral Optical Coherence Tomography (“SOCT”) utilizes Optical Coherence Tomography (“OCT”) to depth-target two or more optical measurements within a blood vessel. OCT achieves depth resolution by the use of optical interferometry. As the path length of the reference arm of the interferometer is varied, the penetration depth at which maximum interference occurs (zero phase difference) in the sample is correspondingly increased. Depth resolution in the range of 10 ?m to 100 ?m enables measurements that may be made within more narrow spectral regions (in the range of 1 to 50 nm) in multiple regions of the visible and near infrared spectrum. In one embodiment the light source is configured for three spectral regions centered at 805 nm, 980 nm, and 1050 nm. By comparing the OCT signal at these different spectral positions, the absorption due to tissue and blood analytes may be measured.Type: ApplicationFiled: March 30, 2009Publication date: October 1, 2009Applicant: Nellcor Puritan Bennett LLCInventor: Martin Debreczeny

Publication number: 20080220512Abstract: The present disclosure relates to a tunable laser-based spectroscopy system for accurately and non-invasively measuring body water content. The body water content is one of the important health indicators, by which one can quantitatively monitor the hydration level of body and determine if it is necessary to supplement or reduce the body water. The disclosed systems, devices, and/or methods may improve wavelength accuracy, wavelength resolution, optical spectral power density, signal-to-noise ration, and available implementation options for the spectroscopy system.Type: ApplicationFiled: March 9, 2007Publication date: September 11, 2008Applicant: Nellcor Puritan Bennett LLCInventors: Seungug Koh, Martin Debreczeny, Clark R.
