Patent number: 11241177Abstract: A pulse oximetry device is provided that fixates generally around a user's wrist. The device may include one or more mechanical features that fix the device at, for example, a distal end of a wearer's ulna bone. The device may include one or more projections formed from a suitable material (e.g., elastomer such as silicon) that cause the device to fit snugly against the wearer's wrist and remain in place even when the wearer is moving, thus reducing motion artifacts in signals detected by the device. The device may include one or more mechanical features or fins that reduce ambient or stray light in the measurement area. The device may include one or more detectors, and one or more light sources, each having a different axis resulting from the manner in which each is angled toward a virtual center point of the distal end of a wearer's ulna bone.Type: GrantFiled: December 15, 2017Date of Patent: February 8, 2022Assignee: Oxitone Medical Ltd.Inventors: Leon Eisen, Uzi Ben-Zion, Koby Refael Gil, Ofer Harpak, Avi Shaham

Patent number: 9730622Abstract: A wearable pulse oximetry device and associated methods are provided. In some embodiments, the device includes at least two light sources having different wavelengths and at least one detector responsive to the different wavelengths. The device also includes a structure adapted to fixate at a distal end of the wearer's ulna bone at a fixated area. The light sources having different wavelengths and the at least one detector are fixed within, or adjacent to, the structure such that when the structure fixates at the fixated area the light sources and the at least one detector are positioned adjacent to the distal end of the ulna, and the at least one detector is positioned to detect light emitted from the at least two light sources.Type: GrantFiled: April 12, 2016Date of Patent: August 15, 2017Assignee: Oxitone Medical Ltd.Inventors: Leon Eisen, Ilya Fine, Leonid Goldinov

Patent number: 9314197Abstract: A pulse oximetry device that is mounted on a wrist strap and fixates an area above a distal end of the ulna with a dome shaped structure. This area is used as measuring area. The measurement is carried out by a detector positioned above the fixated area, that detects light emitted by light sources having different wave lengths that are located at a periphery of the fixated area. Hence, the reflections are measured at neither a reflection mode nor a transmission mode, but are at an angle between 20° and 160° from the emitted light. This mode, termed trans-illumination, allows achieving an excellent signal to noise ratio that for the first time enables continuous and reliable measurement of oximetry data on the wrist.Type: GrantFiled: August 26, 2012Date of Patent: April 19, 2016Assignee: OXITONE MEDICAL LTD.Inventors: Leon Eisen, Ilya Fine, Leonid Goldinov

Patent number: 9149216Abstract: A system and method for measuring one or more light-absorption related blood analyte concentration parameters of a mammalian subject, is disclosed. In some embodiments, the system comprises: a) a photoplethysmography (PPG) device configured to effect a PPG measurement by illuminating skin of the subject with at least two distinct wavelengths of light and determining relative absorbance at each of the wavelengths; b) a dynamic light scattering measurement (DLS) device configured to effect a DLS measurement of the subject to rheologically measure a pulse parameter of the subject; and c) electronic circuitry configured to: i) temporally correlating the results of the PPG and DLS measurements; and ii) accordance with the temporal correlation between the PPG and DLS measurements, assessing value(s) of the one or more light-absorption related blood analyte concentration parameter(s).Type: GrantFiled: October 1, 2014Date of Patent: October 6, 2015Assignee: Oxitone Medical Ltd.Inventors: Leon Eisen, Alexander Kaminsky, Ilya Fine
