METHOD AND SYSTEM OF MONITORING RESPIRATORY SIGNAL BY RADIO
First Claim
1. A system of monitoring a respiratory signal by radio, the system comprising:
- a connector that is connected to opposite ends of a rubber waistband, the rubber waistband being mounted on a lower garment of a testee and being made of rubber including conductive particles;
a radio transmitter that is electrically connected with the connector, converts a change in electric resistance, which is caused by a change in abdominal circumference measured through the rubber waistband during respiration, into a voltage signal, performs analog/digital (A/D) conversion on the voltage signal, and transmits the converted digital signal to a short distance by radio using a wireless communication protocol for ZigBee; and
a radio receiver that receives the respiratory signal, transmitted by radio using the ZigBee wireless communication protocol, through a reception antenna, converts the respiratory signal into serial information, and outputs the converted serial information through a RS-232 port,wherein the respiratory signal is monitored by calculating the input respiratory signal and checkup parameters at the radio receiver, and outputting the calculated result to a monitor screen.

Abstract
A method and system is provided for monitoring a respiratory signal by radio. The method includes the steps of converting a change in electric resistance, which is caused by a change in abdominal circumference measured through a rubber waistband that is made of conductive rubber and is mounted on a lower garment of a testee during respiration, into a voltage signal, performing A/D conversion on the voltage signal, and transmitting the converted digital signal a short distance by radio using a wireless communication protocol for ZigBee, and receiving the respiratory signal transmitted by radio, transmitting it to a computer unit by wire through an RS-232 port that is a serial communication port, and enabling a tester to monitor the respiratory signal through a screen.
