Method and apparatus for cufflessly and non-invasively measuring wrist blood pressure in association with communication device
First Claim
1. A method of cufflessly and non-invasively measuring wrist blood pressure in association with a communication device, the method comprising:
- (a) detecting an electrocardiogram (ECG) and pulse wave signals from a wrist region of a user using an ECG sensor and a pressure sensor;
(b) detecting feature points from the ECG and pulse wave signals detected from the user;
(c) extracting variables for calculating a highest blood pressure and a lowest blood pressure by applying the feature points detected in step (b) to a blood pressure calculation algorithm; and
(d) calculating the highest blood pressure and the lowest blood pressure of the user by deducing a scatter diagram using the extracted variables.

Abstract
A method of cufflessly and non-invasively measuring blood pressure in a wrist region of a patient in association with a communication device that relays the information being measured includes: detecting a magnitude difference between a plurality of pulse wave signals detected from a wrist of a user; detecting feature points from an electrocardiogram (ECG) and pulse wave signals detected from the user; extracting variables needed to calculate the highest blood pressure and the lowest blood pressure using the detected feature points; and calculating the highest blood pressure and the lowest blood pressure of the user by deducing a scatter diagram using the extracted variables.
