Abstract
A non-invasive automatic blood pressure measuring apparatus consisting of a blood flow meter non-invasively detecting the blood flow of the arteries on the proximal or distal side of the cuff, a blood flow standing up point detecting means detecting the standing up point of the blood flow signal output from the blood flow meter in the decompression process of the internal pressure in the cuff and a blood flow returning point detecting means detecting the returning point of the blood flow signal to the steady state in the further successive decompression process, and detecting the internal pressure in the cuff of the standing up point as the maximal value of the blood pressure and the internal pressure in the cuff of the returning point as the minimal value of the blood pressure.
