  • Publication number: 20200405226
    Abstract: An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service. The opioid overdose monitoring service notifies a first set of contacts when the opioid monitoring information indicates a non-distress stats and notifies a second set of contact when the opioid monitoring information indicates an overdose event. The notification can be a phone call or text message to a specified person, emergency personnel, or first responders, and can include the location of the smart mobile device. The smart mobile device can also include the location of the nearest treatment center having emergency medication used in treating opioid overdose, such as naloxone.

  • Publication number: 20200367796
    Abstract: Disclosed herein is a physiological measurement system that can automatically adjust the number of wavelengths used based on the quality of a sensor signal that is reflective of an optical radiation detected at a sensor after tissue attenuation. The signal quality is examined to determine if it is sufficient to support the use of a full set of wavelengths. If it is determined to be insufficient to support the full set, a reduced number of wavelengths is used.

  • Publication number: 20200163598
    Abstract: A regional oximetry sensor can have a sensor head configured to secure to skin of a user and a stem extending from the sensor head. The sensor head can include an emitter configured to transmit optical radiation into the skin and at least one detector configured to receive the optical radiation after attenuation by blood flow within the skin. The stem can be configured to transmit electrical signals from the sensor head to a cable. A plurality of notches can extend from a perimeter of the sensor head towards an interior thereof. The plurality of notches can form a plurality of independently flexible cutouts in the sensor head configured to allow for movement of at least a portion of the skin of the user underlying the sensor head when the regional oximetry sensor is in use.

  • Patent number: 10617335
    Abstract: A regional oximetry sensor has a sensor head attachable to a patient skin surface so as to transmit optical radiation into the skin and receive that optical radiation after attenuation by blood flow within the skin. The sensor includes windows that press into the skin to maximize optical transmission. A stem extending from the sensor head transmits electrical signals between the sensor head and an attached cable. In a peel resistant configuration, the stem is terminated interior to the sensor head and away from a sensor head edge so as to define feet along either side of the stem distal the stem termination. The stem interior termination transforms a peel load on a sensor head adhesive to less challenging tension and shear loads on the sensor head adhesive.
