First Claim
1. A device for measuring an electrocardiographic wave and sphygmus, comprising:
- electrocardiographic wave detecting means for detecting an electrocardiographic wave in a human body to generate an electric signal;
first amplifying means for amplifying said electric signal received from said electrocardiographic wave detecting means to generate an electrocardiographic wave signal;
first gain data storing means for storing first gain data to control the gain of said first amplifying means;
sphygmus detecting means for detecting sphygmus in a blood vessel to generate an electric signal;
second amplifying means for amplifying the electric signal received from said sphygmus detecting means to generate a sphygmus signal;
second gain data storing means for storing second gain data to control the gain of said second amplifying means;
judging means for determining whether the electrocardiographic wave signal generated by said first amplifying means and the sphygmus signal generated by said second amplifying means are in correspondence with each other; and
gain control means for changing one of said first and second gain data to control the gain of its associated amplifying means when said judging means determines that said electrocardiographic wave signal and said sphygmus signal are not in correspondence with each other.

Abstract
A device is used for precisely measuring an electrocardiographic wave and sphygmus. The device displays a number of sphygmus or the highest and lowest blood pressure on the basis of measured data. In the device, it is judged if an electrocardiographic wave signal generated from an electrocardiographic wave detecting circuit and the sphygmus signal generated from a sphygmus detecting circuit have been output in a corresponding manner to each other. If not, or if one of the above signals has not been detected, either the gain of the electrocardiographic wave detecting circuit or the gain of the sphygmus detecting circuit is increased so as to allow a precise detection of the signal.
