APPARATUS AND METHOD FOR AUTOMATIC MEASUREMENT AND WIRELESS TRANSMISSION OF BLOOD PRESSURE VALUES BASED ON OSCILLOMETRIC METHOD AND K-SOUND METHOD

摘要

PURPOSE: An apparatus and a method for wireless data transmitting automatic blood-pressure measurement based on an oscillometric method and a K-sound method are provided to be adopted to a remote diagnosis and a home diagnosis by periodically transmitting blood-pressure values. CONSTITUTION: A pressure sensor(220) detects a pressurized absolute pressure and the oscillation waveform of an artery pulse. A contact microphone(120) including a piezo film is contacted with a position on which the artery pulse is generated, and is located in a cuff. The contact microphone detects a K-sound which is generated in case of the decompression of the cuff.
