Patent number: 11672448Abstract: A probe tip of an oximeter device includes first and second printed circuit boards (PCBs) that are coupled to the ends of optical fibers that transmit light between the PCBs and into patient tissue that is to be measured by the oximeter device. The PCBs are oriented at an angle between zero and ninety degrees so that the fibers have a curved shape between the locations at which the fibers are coupled to the first and second PCBs. The angular orientation of the PCBs and curved shape of the fibers allows the fibers to have a longer length than if the fibers were straight and allows for light transmitted through the fibers to have a uniform distribution across a cross-section of the fibers as the light is emitted from the fibers into patient tissue. The uniform distribution of light transmitted into patient tissue allows for reliable oximetry measurements.Type: GrantFiled: January 11, 2021Date of Patent: June 13, 2023Assignee: ViOptix, Inc.Inventors: Kate LeeAnn Bechtel, Alex Michael Margiott, Jennifer Elizabeth Keating, Kimberly Merritt Shultz

Patent number: 11660008Abstract: A method and a system for determining an in vivo transit distance and a corresponding transit time for an arterial pulse. An example system comprises a radar receiver connected to a processor to perform time-resolved measurements of reflections of wave pulses and to spectrally filter the reflections to select spectral components associated with the arterial pulse. The resulting signal samples are then organized into groups corresponding to different wave pulses, and the groups are processed to identify samples corresponding to a first arterial pulse point and a second arterial pulse point on the body of a subject, and the identified samples are further processed to determine the in vivo transit distance and the corresponding transit time for the arterial pulse. In some embodiments, a collection of arterial pulse points detected by the measurements may be mapped onto a reference constellation for a more-accurate determination of the in vivo transit distance.Type: GrantFiled: January 12, 2018Date of Patent: May 30, 2023Assignee: Nokia Technologies OyInventors: Durgaprasad Shamain, Klaus Doppler, Swetha Muniraju, Eric Torkildson

Patent number: 11647924Abstract: Apparatus and methods provide wireless, disposable, continuous pulse oximeter sensor technology, useful and beneficial for a number of applications including relatively extended periods of data collection, and/or packaged in compact and easy-to-use assemblies. Economic fabrication and use provides flexible methodologies that can reduce the overall costs of monitoring and collecting patient's physiological data, and provide relatively greater ease and comfort to the patient. A disposable wireless continuous pulse oximeter sensor has a reduced emitter-detector separation, a low-power frontend, and a low-cost processor that sends waveforms to a host device so that the host can calculate and display the parameters of interest. Complications created by the reduced distance between emitter and detector are minimized by using an emitter-detector assembly with an optically dark background, and a bandage for improved optical compliance.Type: GrantFiled: July 1, 2020Date of Patent: May 16, 2023Assignee: True Wearables, Inc.Inventors: Marcelo Malini Lamego, Tatiana Buticosky Lamego
