APPARATUS AND METHOD FOR ESTIMATING BLOOD PRESSURE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17968309 Titled 'APPARATUS AND METHOD FOR ESTIMATING BLOOD PRESSURE'
Simplified Explanation
This abstract describes an apparatus designed to estimate blood pressure. The apparatus includes a sensor that measures a signal called photoplethysmogram (PPG) from an object, such as a person's finger. It also includes a force sensor that measures the force between the object and the PPG sensor. The apparatus uses a processor to divide a range of blood pressure values into different classes. It then takes the measured PPG signal and force signal and inputs them into a blood pressure estimation model. The model calculates probability values for each class based on the input signals. Finally, the apparatus estimates the blood pressure by using the obtained probability values for the different classes.
Original Abstract Submitted
An apparatus for estimating blood pressure includes: a photoplethysmogram (PPG) sensor configured to measure a PPG signal from an object; a force sensor configured to measure a force signal acting between the object and the PPG sensor; and a processor configured to (i) divide a predetermined blood pressure range into a plurality of classes, (ii) input the measured PPG signal and the measured force signal into a blood pressure estimation model to obtain the probability values for each of the classes, and (iii) estimate blood pressure based on the obtained probability values for the respective classes.
