Patent number: 7198756Abstract: There is a need within the medical community for non-invasive instruments to measure critical physiologic parameters at the point of care. Such a technique may be applicable to a wide variety of commonly monitored physiologic parameters during critical care patient management. The invention is directed to a method of measuring the pH of a patient's tissue. The method includes measuring the optical signal from a specie whose fluorescence is pH sensitive, such as nicotinamide adenine dinucleotide (NADH) and also measuring the optical signal from a second biological marker, such as FAD, the fluorescence from the second marker being substantially insensitive to pH. The method includes determining the patient's pH by using the first and second optical signals.Type: GrantFiled: July 11, 2002Date of Patent: April 3, 2007Assignee: Optical Sensors IncorporatedInventors: Victor E. Kimball, Steven C. Furlong, Irvin Pierskalla

Patent number: 6865407Abstract: There is a need for a non-invasive method of calibrating medical devices at the point of care, where the calibration is performed without the removal of blood or bodily fluids. The invention is directed to an approach for calibrating a first non-invasive sensor in which the tissue being measured is modulated in some way so as to after the value of the parameter being measured by the first optical sensor. A second sensor detects another parameter that also changes with the modulation. The second sensor is absolutely calibrated. Where there is a known relationship between the first and second parameters, a calibration may be derived for the first sensor. Such a technique is applicable to calibrating non-invasive sensors for monitoring a wide variety of physiologic parameters including, inter alia, glucose, blood gases, blood electrolytes and blood pH.Type: GrantFiled: July 11, 2002Date of Patent: March 8, 2005Assignee: Optical Sensors, Inc.Inventors: Victor E.

Publication number: 20040010185Abstract: Generally, the present invention relates to a method for non-invasive optical measurements at at physiologic sites that may reduce or minimize the effects of skin chemistries that optically interfere with the desired optical measurement. An embodiment of the invention is directed to a method of making an optically-based, non-invasive optical measurement of a first physiologic parameter of a patient. The method comprises probing the tissue of a first epithelial site with a first probe light propagating from the optical sensor and detecting a first signal light received from the first assay site with the optical sensor. The method also comprises measuring a value of a second parameter of the patient and determining the level of the first physiologic parameter within the tissue of the first assay site based on the detected first signal light and on the measured second parameter of the patient.Type: ApplicationFiled: July 11, 2002Publication date: January 15, 2004Applicant: Optical Sensors, Inc.Inventors: Victor E.

Patent number: 5714121Abstract: A method is provided for manufacturing a fiber optic sensor for detecting or measuring the concentration of carbon dioxide in a sample fluid. The method involves incorporation of a fluorescent indicator composition in a silicone capsule slidably arranged over the tip of a fiber optic, sealed with a suitable adhesive. To amplify the detectable signal obtained, the capsule is preferably fabricated so as to contain reflective particles, and tapers to a narrow tip. Novel optical sensors, manufactured using the aforementioned method, are provided as well.Type: GrantFiled: September 28, 1995Date of Patent: February 3, 1998Assignee: Optical Sensors IncorporatedInventors: Jason E.

Patent number: 5672515Abstract: A simultaneous dual excitation/single emission ratiometric method using fiber optic sensors is provided for detecting or measuring a parameter of interest in a sample, including pH, concentration of gases such as CO.sub.2, and the like. The method involves simultaneously providing modulated optical light corresponding to first and second regions of an indicator species' absorption or excitation spectrum, detecting modulated emission signals from the indicator species, demodulating the emission signals, calculating the apparent quantity of analyte present in the sample from the indicator emission signals and correcting the apparent quantity of analyte present for variations resulting from external factors, by determining the ratio of the demodulated indicator emission signals. An apparatus is provided for performing the method as well.Type: GrantFiled: September 12, 1995Date of Patent: September 30, 1997Assignee: Optical Sensors IncorporatedInventor: Steven C. Furlong

Patent number: 4717225Abstract: A polarizing optical fiber has a core formed of a plurality of layers of dielectrics having different refractive indices. The dielectric layers form a composite structure having different refractive indices for light of different polarizations. The differing refractive indices cause the polarization states of light guided by the fiber to be non-degenerate so that energy ordinarily will not couple from one polarization to the other. The fiber includes a cladding that may have a refractive index either less than both core indices to provide a polarization maintaining fiber or greater than or equal to one of the core indices to provide a polarizing fiber. The method of fabrication of the layered core form birefringent optical fiber includes forming a structure of a plurality of layers of the dielectrics, heating the structure to form a monolith, stretching the monolith to form the fiber core, and adding the cladding to the core.Type: GrantFiled: May 15, 1985Date of Patent: January 5, 1988Assignee: Litton Systems, Inc.Inventors: John R.
