  • Patent number: 11219391
    Abstract: A pulse oximeter may reduce power consumption in the absence of overriding conditions. Various sampling mechanisms may be used individually or in combination. Various parameters may be monitored to trigger or override a reduced power consumption state. In this manner, a pulse oximeter can lower power consumption without sacrificing performance during, for example, high noise conditions or oxygen desaturations.

  • Patent number: 11207007
    Abstract: A system and a method for creating a stable and reproducible interface of an optical sensor system for measuring blood glucose levels in biological tissue include a dual wedge prism sensor attached to a disposable optic that comprises a focusing lens and an optical window. The disposable optic adheres to the skin to allow a patient to take multiple readings or scans at the same location. The disposable optic includes a Petzval surface placed flush against the skin to maintain the focal point of the optical beam on the surface of the skin. Additionally, the integrity of the sensor signal is maximized by varying the rotation rates of the dual wedge prisms over time in relation to the depth scan rate of the sensor. Optimally, a medium may be injected between the disposable and the skin to match the respective refractive indices and optimize the signal collection of the sensor.

  • Patent number: 11191485
    Abstract: A physiological monitor has a sensor port configured to attach and communicate with a sensor. A processor board is in communications with the sensor port and has a board digital signal processor (DSP). Firmware residing on the processor board is executable by the board DSP so as to calculate physiological parameters in response to a sensor signal received from the sensor. Upgrade tools are individually attachable to the sensor port in lieu of the sensor so as to designate to the processor board which of the physiological parameters, if any, to calculate when the sensor is attached to the sensor port.

  • Patent number: 11191484
    Abstract: Various sensor tapes can improve securing of a non-invasive optical sensor to a surface of a medium for taking noninvasive measurement of characteristics of the medium. The sensor tape can taper from a wide end to a narrow end. The sensor tape can transition from a wide portion to a narrow portion in a step-like change or slope. The sensor tape can have staggered portions. The various tapes can be used with an L-shaped sensor. The various tapes can increase contact surface between the surface of the medium and an adhesive side of the tape so as to reduce motion-induced noise.

  • Patent number: 11179111
    Abstract: Automated critical congenital heart defect (“CCHD”) screening systems and processes are described. A caregiver may be guided to use a single or dual sensor pulse oximeter to obtain pre- and post-ductal blood oxygenation measurements. A delta of the measurements indicates the possible existence or nonexistence of a CCHD. Errors in the measurements are reduced by a configurable measurement confidence threshold based on, for example, a perfusion index. Measurement data may be stored and retrieved from a remote data processing center for repeated screenings.

  • Patent number: 11133105
    Abstract: Medical patient monitoring devices that have the capability of detecting the physical proximity of a clinician are disclosed. The medical patient monitoring devices may be configured to perform a first selected action when the presence of a clinician is detected in a first detection area, and to perform a second selected action when the presence of the clinician is detected in a second detection area. The medical patient monitoring devices may be configured to determine whether a clinician is present in a detection area based on the strength of a signal from a clinician token, and based on a signal strength adjustment value associated with the clinician token. When the presence of a clinician is detected in a detection area, the medical patient monitoring devices may be configured to perform a predetermined action that is determined from a remote database communicatively coupled thereto.
