Monitoring apparatus of arterial pulses and method for the same
First Claim
1. A monitoring apparatus of arterial pulses, comprising:
- an antenna board being comprised of;
a transmission antenna radiating ultra wideband electromagnetic pulses to an arterial blood vessel; and
a reception antenna for receiving the ultra wideband electromagnetic pulses scattered by the arterial blood vessel;
an analog board with a plurality of electronic devices acquiring analog signals representing the arterial pluses of the arterial blood vessel;
a digital board with a plurality of electronic devices digitalizing the analog signal; and
a display device showing the arterial pulses.

Abstract
A monitoring apparatus includes an antenna board including a transmission antenna for transmitting an ultra wideband electromagnetic wave to an arterial blood vessel and a reception antenna for receiving the ultra wideband electromagnetic wave scattered by the arterial blood vessel, an analog board with a plurality of electronic devices for acquiring analog signals representing the arterial pluses of the arterial blood vessel, a digital board with a plurality of electronic devices for digitalizing the analog signal, and a display device for showing the arterial pulses. The method for acquiring arterial pulses first radiates an ultra wideband electromagnetic wave to an arterial blood vessel, and measures the phase difference between the ultra wideband electromagnetic wave scattered by the arterial blood vessel and the reference ultra wideband electromagnetic wave. Finally, the arterial pulses are acquired based on the variation of the phase difference.
