Method and Device for Measuring Blood Flow Velocity
First Claim
1. A method for measuring blood flow velocity, comprising the steps of:
- placing a first and second blood vessel signal detectors on a body of a person to be measured, wherein the first blood vessel signal detector is electrically connected to a first blood vessel signal analyzer, the second blood vessel signal detector is electrically connected to a second blood vessel signal analyzer, and the first and second blood vessel signal detectors are located a predetermined distance from each other;
using the first and second blood vessel signal analyzers to record the blood signal of the person to be measured at a predetermined time interval;
setting an interval of time from the moment a specific blood vessel signal appears in a record of the first blood vessel signal analyzer to the moment the specific blood vessel signal appears in a record of the second blood vessel signal analyzer to be a predetermined time period; and
dividing a value of the predetermined distance by a value of the predetermined time period can obtain a blood flow velocity between the first and second blood vessel signal detectors.

Abstract
A method for measuring blood flow velocity comprises the steps of: placing a first and second blood vessel signal detectors on a body of a person to be measured in such a manner that the first and second blood vessel signal detectors are located a predetermined distance from each other; using the first and second blood vessel signal analyzers to record the blood signal at a predetermined time interval; setting an interval of time from the moment a specific blood vessel signal appears in a record of the first blood vessel signal analyzer to the moment the specific blood vessel signal appears in a record of the second blood vessel signal analyzer to be a predetermined time period; and dividing a value of the predetermined distance by a value of the predetermined time period can get a blood flow velocity.

10. A device for measuring blood flow velocity comprising:
-
a controller; a first blood vessel signal analyzer electrically connected to the controller; a second blood vessel signal analyzer electrically connected to the controller; a first blood vessel signal detector electrically connected to the first blood vessel analyzer; and a second blood vessel signal detector electrically connected to the second blood vessel analyzer; wherein a first blood signal detected and analyzed by the first blood vessel signal detector and the first blood vessel signal analyzer and a second blood signal detected and analyzed by the second blood vessel signal detector and the first blood vessel signal analyzer are all recorded by the controller, and then the controller calculate a blood flow velocity of the person to be measured. - View Dependent Claims (11)
