APPARATUS FOR EVALUATING CARDIOVASCULAR FUNCTIONS
First Claim
1. An apparatus for evaluating cardiovascular functions, comprising:
- an inflatable cuff applied to a testee, connected to a pressure sensor;
a CPU controlling the inflatable cuff via the pressure sensor to perform a pressure procedure and a regulation procedure, detecting a resonance signal and a pulse signal during the pressure procedure and the regulation procedure;
at least two sensing electrodes contacting with a skin of the testee, acquiring electrocardiogram (ECG) signals; and
a signal processor module receiving the resonance signal, the pulse signal, and the ECG signals, converting the resonance, pulse and ECG signals into a digital format and delivering to the CPU for operation of physiological signals to acquire at least one blood pressure parameter, at least one blood vessel parameter, and at least one ECG parameter.

Abstract
An apparatus is provided for evaluating cardiovascular functions. The apparatus combines the principles of measuring pressure and pulse signals, and monitors blood pressure, pulse wave velocity and electrocardiogram (ECG) signals simultaneously. An inflatable cuff measures blood pressure and pulse wave velocity. The apparatus also calculates systolic pressure, diastolic pressure, mean arterial pressure and other parameters related to blood pressure. The apparatus not only calculates vascular Stiffness Index (SI), vascular Reflection Index (RI) and other arterial related parameters but also Pulse Wave Velocity (PWV), heartbeat, QRS interval, ST segment, and other ECG parameters.
