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.

1 Independent Claims

  • Claim 1. A method of obtaining blood pressure data, implemented using an intelligent oscillometric blood pressure measurement (IOBPM) device comprising an inflatable cuff, apressure sensor, communication circuitry, a memory, and one or more processors, the method comprising: pairing the IOBPM device and a second device through the communication circuitry, wherein the second device is associated with an identity of a userand the IOBPM is not associated with the identity of the userobtaining, by the one or more processors, data associated with the user, wherein the data associated with the user comprise: (a) data indicating that the IOBPM device and the second deviceare paired, and (b) data indicating the second device is associated with the identity of the userobtaining, by the one or more processors, oscillometric blood pressure data from the user and associating the oscillometric blood pressure data with theidentity of the user, wherein the oscillometric blood pressure data are generated by the pressure sensordetermining, by the one or more processors, the identity of the user using the oscillometric blood pressure data, comprising applying a classifierto the oscillometric blood pressure data to determine the identity of the userand sending, by the one or more processors through the communication circuitry, data indicating the identity of the user and the blood pressure data to the second device.
  • Claim 14. A method of obtaining blood pressure data, implemented using an intelligent oscillometric blood pressure measurement device and a second device, wherein the intelligent oscillometric blood pressure measurement device comprises an inflatablecuff, a pressure sensor, and first communication circuitry, and wherein the second device comprises a memory, second communication circuitry, and one or more processors, the method comprising: receiving, by the second device, oscillometric blood pressuredata from the intelligent oscillometric blood pressure measurement device via the first communication circuitry and the second communication circuitry, wherein the oscillometric blood pressure data are obtained from a user using an oscillometric bloodpressure technique, and the oscillometric blood pressure data comprise pressure oscillation data and blood pressure dataand determining, by the one or more processors of the second device, an identity of the user using the oscillometric blood pressuredata, comprising applying a classifier to the oscillometric blood pressure data to determine the identity of the user.
