Latest Patents
Among his latest patents, Takuo Aoyagi's work on pulse oximetry and pulse oximeters deserves particular attention. His invention focuses on a sophisticated method that includes irradiating living tissue with a plurality of light beams of different wavelengths. The light beams are received after being transmitted through or reflected from the tissue, and converted into electric signals representative of the different wavelengths. A systematic approach is utilized whereby the time-series data of these electrical signals is segmented, leading to the calculation of SaO2 based on regression analysis of slope values. Moreover, the implementation of histograms allows for the determination of SpO2, which is essential for patient monitoring.
Another noteworthy patent addresses time-segmented pulse oximetry and pulse oximeters. This invention involves measuring oxygen saturation through the use of dual light beams with distinct wavelengths. The resulting electrical signals are segmented into manageable time sections, and gradients of regression lines are computed, further refining the accuracy of oxygen saturation measurements.
