  • Patent number: 12029536
    Abstract: A device for monitoring heart rate or blood oxygen level during exercise is disclosed having sensors (106) and emitters (104), wherein the sensors (106) are used to monitor transmission from each of the emitters (104) in turn. This provides a possibility that a smaller device can be provided since less sensors and emitters can be used while obtaining more number of observations. In some embodiments the repeated use of sensors with different emitters introduces redundancy into the device so that the device is more robust and may function even in the event that one or two of the emitters and sensors have broken down.

  • Patent number: 12016689
    Abstract: An oximeter probe is user configurable for being in an absolute reporting mode and a relativey reporting mode for measured values. The measured values for the absolute and relative modes include absolute oxygen saturation, relative oxygen saturation, absolute hemoglobin content, relative hemoglobin content, absolute blood volume, relative blood volume. The relative modes and absolute modes for determining and reporting relative or absolute hemoglobin content or relative or absolute blood volume for individual patients are beneficial when determining the efficacy of administered medications, such as epinephrine, that effect blood flow, but not oxygen saturation, in tissue, such as skin. The oximeter probe in these relative modes displays the efficacy of the administered medication as reported values for relative hemoglobin content or relative blood volume fall or rise.

  • Patent number: 11723564
    Abstract: A compact optical sensor is used to determine heart rate, hemoglobin, hydration, peptides, or oxygen saturation using a light source and a single photodiode. The single photodiode has a first filter and a second filter. The first filter is closer to the light source and is transparent to green light and blocks red light. The second filter is farther from the light source and is transparent to red light and blocks green light. This arrangement of the filters facilitates acquisition of backscattered light from desired depths of measurement within the body of a user. At a first time, the light source emits red light and first output from the photodiode is determined. At a second time, the light source emits green light and second output from the photodiode is determined. The optical sensor determines oxygen saturation using the first output and heart rate using the second output.

The sensor band has a first mass and the sensing element has a second mass that is less than the first mass. The sensing element is movably secured to the sensor band via a biasing element, and the biasing element is configured to urge the sensing element into contact with a portion of the appendage. The biasing element decouples motion of the sensor band from the sensing element, and the at least one member decouples motion between the sensor band and the second band.
