  • Patent number: 11103148
    Abstract: The invention provides a body-worn system that continuously measures pulse oximetry and blood pressure, along with motion, posture, and activity level, from an ambulatory patient. The system features an oximetry probe that comfortably clips to the base of the patient's thumb, thereby freeing up their fingers for conventional activities in a hospital, such as reading and eating. The probe secures to the thumb and measures time-dependent signals corresponding to LEDs operating near 660 and 905 nm. Analog versions of these signals pass through a low-profile cable to a wrist-worn transceiver that encloses a processing unit. Also within the wrist-worn transceiver is an accelerometer, a wireless system that sends information through a network to a remote receiver, e.g. a computer located in a central nursing station.

  • Patent number: 11096592
    Abstract: A sensor module includes a light emitter that emits light beams including near-infrared light beams towards a subject; a light receiver that receives light beams having passed through the subject; and a controller that estimates biological information based on signals output from the light receiver. The light emitter includes a plurality of light emitting elements that emit near-infrared light beams having central wavelengths different from each other. The light emitter produces sets of light emissions by causing the plurality of light emitting elements to sequentially and intermittently emit the near-infrared light beams. In given two consecutive sets of light emissions produced by the light emitter, a second non-light-emission period of time T4 is longer than a first non-light-emission period of time T2. The controller estimates the biological information in a processing period of time T41 that is set in correspondence with the second non-light-emission period of time T4.

  • Patent number: 11071479
    Abstract: A handheld device measures all vital signs and some hemodynamic parameters from the human body and transmits measured information wirelessly to a web-based system, where the information can be analyzed by a clinician to help diagnose a patient. The system utilizes our discovery that bio-impedance signals used to determine vital signs and hemodynamic parameters can be measured over a conduction pathway extending from the patient's wrist to a location on their thoracic cavity, e.g. their chest or navel. The device's form factor can include re-usable electrode materials to reduce costs. Measurements made by the handheld device, which use the belly button as a ‘fiducial’ marker, facilitate consistent, daily measurements, thereby reducing positioning errors that reduce accuracy of standard impedance measurements. In this and other ways, the handheld device provides an effective tool for characterizing patients with chronic diseases, such as heart failure, renal disease, and hypertension.

  • Patent number: 11058301
    Abstract: An optical detection method and system are provided. Sample light is delivered into an anatomical structure having a target voxel, whereby a portion of the sample light passing through the target voxel is scattered by the anatomical structure as signal light, and another portion of the sample light not passing through the target voxel is scattered by the anatomical structure as background light that is combined with the signal light to create a sample light pattern. The sample light pattern and the reference light having an M number of different phases are concurrently combined to respectively generate an M number of interference light patterns. The M number of interference light patterns are detected. M pluralities of values representative of spatial components of the respective M number of interference light patterns are generated, and a physiologically-dependent optical parameter of the target voxel is determined based on the M pluralities of values.
