Publication number: 20200237274Abstract: Physiologic sensors and methods of application are described. These sensors function by detecting recently discovered variations in the spectral optical density at two or more wavelengths of light diffused through the skin. These variations in spectral optical density have been found to consistently and uniquely relate to changes in the availability of oxygen in the skin tissue, relative to the skin tissue's current need for oxygen, which we have termed Physiology Index (PI). Current use of blood gas analysis and pulse oximetry provides physiologic insight only to blood oxygen content and cannot detect the status of energy conversion metabolism at the tissue level. By contrast, the PI signal uniquely portrays when the skin tissue is receiving ‘less than enough oxygen,’ just the right amount of oxygen,? or ‘more than enough oxygen’ to enable aerobic energy conversion metabolism.Type: ApplicationFiled: March 23, 2020Publication date: July 30, 2020Applicant: REVEAL BIOSENSORS, INC.Inventor: Guy Meredith HATCH

Patent number: 10619198Abstract: The present invention relates to a primer for PCR obtained by, directly or through inosine as a linker, linking a complementary nucleotide sequence or a complementary nucleotide sequence including a mis-matched nucleotide sequence to the 5?-terminal of a forward or reverse primer; and to a PCR method including a step of mixing a nucleic acid template in a PCR composition including the primer and then performing PCR on the mixture. The primer for PCR of the present invention includes a complementary nucleotide sequence or a mis-matched nucleotide sequence in a complementary nucleotide sequence, which is linked to the 5?-terminal thereof directly or via a linker, thereby lowering the sensitivity increase due to the increase in amplification products and reducing non-specifically occurring reactions in PCR.Type: GrantFiled: January 7, 2016Date of Patent: April 14, 2020Assignee: SD BIOSENSOR, Inc.Inventors: Yoo-Deok Won, Hae-joon Park, Sunyoung Lee

Publication number: 20200085321Abstract: Persons with sleep disordered breathing (SDB) may, or may not, recognize that they have symptoms of SDB, and/or that they may be at-risk of, or suffering certain health problems associated with SDB, including death. The disclosed Energy Conversion Monitor (ECM) sensor, when embodied, for example, in a wearable upper-armband format, has been demonstrated to be more sensitive and responsive than pulse oximetry monitoring of blood oxygen saturation as an indication of hypoxic stress induced by SDB, and is compatible with: (1) inclusion in sleep laboratory polysomnograph (PSG) testing instrumentation, (2) home-based diagnostic testing for SDB, (3) control of home-use airway therapy devices, (4) continuous remote surveillance and refinement of airway therapy, and (5) spot-check and continuous surveillance of sleep quality in the general population. The disclosed ECM also provides new measurements of physiologic stress during and following exercise.Type: ApplicationFiled: September 16, 2019Publication date: March 19, 2020Applicant: REVEAL BIOSENSORS, INC.Inventor: Guy Meredith Hatch

Patent number: 9915608Abstract: A method and apparatus for non-invasively determining a concentration of glucose in a subject using optical excitation and detection is provided. The method includes emitting an exciter beam (B1) to irradiate a portion (130) of tissue of the subject, causing physical and chemical changes in the surface, and causing an initial back scattering (D1) of light. The method further includes periodically emitting a probe beam (B2) which irradiates the portion of tissue and causes periodic back scatterings (D2) of light. The initial and periodic back scatterings are detected and converted into electrical signals of at least the amplitude, frequency or decay time of the physical and chemical changes, the back scatterings being modulated by the physical and chemical changes. By differentiating over time at least one of the amplitude, frequency or decay time of the physical and chemical changes, the concentration of glucose may be determined.Type: GrantFiled: October 31, 2008Date of Patent: March 13, 2018Assignee: BioSensor, Inc.Inventors: Peter Schultz, Arkady Amosov, Natalia Izvarina, Sergey Kravetz

Patent number: 9857365Abstract: Described are immunoassay kits having a conjugate structure separate from an immunochromatographic strip in which the conjugate structure is freeze-dried with uniform droplet size, and related compositions and methods. The unique structure of the kits described here permits sample containing analyte to be reacted uniformly with the conjugate structure before being subjected to immunochromatography by application to the strip. This results in improved performance of the assay. In addition, the freeze-dried conjugate structure can be stored without contamination and is easy to carry. In addition, the freeze-dried conjugate structure can be rapidly and uniformly dissolved so that it is immediately allowed to react with a mixture of a buffer and a sample, the reaction product then being analyzed by immunochromatography, making it suitable for use in point-of-care testing.Type: GrantFiled: May 31, 2013Date of Patent: January 2, 2018Assignee: SD Biosensor, Inc.Inventors: Hyoung Gil Choi, Sung Yub Hong, Hee Young Hwang, Hyo Keun Lee

Publication number: 20110111487Abstract: The present invention relates to a method and apparatus for detecting analytes in a medium, and more particularly the present invention relates to an assay based on light diffraction which appears or changes upon the binding of analytes to their specific receptors laid out in patterns on a substrate, which has high sensitivity due to the appropriate choice of such patterns. The present invention is based on the principle that the pattern of recognition elements, which gives rise to the diffraction of the incident light in a diffraction-based assay, can be chosen in such a way so as to facilitate detection, and to enhance the signal to be detected compared to known gratings such as parallel straight lines. In one aspect the substrate itself has a surface topography designed to enhance the diffraction pattern signals. In another aspect the substrate is a diffractive optic element having the analyte-specific receptors affixed to the optic element.Type: ApplicationFiled: October 28, 2010Publication date: May 12, 2011Applicant: AXELA BIOSENSORS INC.Inventors: M.

Patent number: 7008794Abstract: A method and apparatus for assay of multiple analytes. The method uses a sensing element comprising a substrate upon which is arranged a multiplicity of recognition elements, such that each element is laid out in a predetermined pattern. Each pattern is unique in that it can give rise to a characteristic diffraction pattern in the assay. The patterns may or may not be interpenetrating on the substrate surface. The method of detecting multiple analytes includes contacting the medium of analytes with the patterned substrate, illuminating the substrate by a light source, and detecting any resultant diffraction image. The pattern of diffraction and the intensity of the diffracted signal provides information about the existence of specific analytes and their quantification.Type: GrantFiled: March 22, 2001Date of Patent: March 7, 2006Assignee: Axela Biosensors Inc.Inventors: M.
