Intelligent Inflatable Cuff For Arm-based Blood Pressure Measurement
This disclosure provides devices and methods for estimating blood pressure using intelligent oscillometric blood pressure measurement techniques, where some implementations of the devices include multiple biometric sensors and/or can obtain sensor data from a connected device. In some implementations, the devices automatically determine an identity of a user. In some implementations, the devices automatically provide instructions to users to take blood pressure measurements. In some implementations, the devices applied intelligent inflation techniques to improve user comfort and speed up measurements.
Claim CLM-00001. 1. A method of obtaining blood pressure data, implemented using an intelligent oscillometric blood pressure measurement (IOBPM) device comprising an inflatable cuff, a pressure sensor, communication circuitry, a memory, and one or more processors, the method comprising:
