Abstract
A pulse detecting apparatus includes a combination of a pressure sensor; a minimum value detecting circuit for detecting a minimum value of the output of the pressure sensor; a maximum value detecting circuit for detecting a maximum value of the output of said pressure sensor; pressure applying member for biasing the a pressure sensor upon an artery; a static pressure sensor for detecting the biasing pressure to bias the pressure sensor of the pressure applying means upon the artery; and measured pressure detecting circuit for detecting based upon the output of the static pressure sensor the biasing pressures of said pressure applying member corresponding to the minimum and maximum value detected by said minimum and maximum values detecting means, respectively when the biasing pressure of the pressure applying member is decreased from a given value. A biasing pressure for biasing the pressure sensor of the pressure applying member upon the artery at which pulses necessary for the sphygmic diagnosis can be obtained, that is, the measured pressure, can be accurately determined.
