A recently granted patent (Publication Number: US11911155B2) discloses an apparatus designed for monitoring blood oxygen saturation in a subject. The apparatus, intended to be worn on the upper arm, includes a first light source emitting light of a specific wavelength, a second light source emitting light of a different wavelength, and photodetectors to detect the reflected light within the upper arm. By analyzing the detected light signals, the apparatus can determine the blood oxygen saturation level and provide an output accordingly. The unit features a housing with an arm-facing portion designed to make contact with the upper arm, ensuring accurate readings. Additionally, the apparatus may include a motion sensor to account for movement during readings and a temperature sensor to prompt action if the subject's temperature falls below a certain threshold.

Furthermore, the patent includes details about the configuration of the apparatus, such as the placement of the light sources, photodetectors, and sensors, as well as the inclusion of a strap for securing the unit on the upper arm. The apparatus is equipped with a power source and a charger for convenient recharging, along with instructions stored in memory for operation. The design also incorporates a stabilizing portion and a flexible strap to ensure a secure fit on the subject's arm, with the strap being resiliently deformable to accommodate arm movement. Overall, the patented apparatus offers a comprehensive solution for monitoring blood oxygen saturation levels in a user-friendly and efficient manner, with various features and components working together to provide accurate and reliable results.
