Title:
MEASURING APPARATUS FOR DETECTING MEASURING SIGNAL CORRESPONDING TO BODY ACTION OF ORGANISM IN HEART
Document Type and Number:
Japanese Patent JPH04263836
Kind Code:
A
Abstract:
PURPOSE: To match the characteristic of a measuring device with the necessity and strength of the present body activity at each time in a wide range by forming a two-terminal network feeding a measured current or dropping a measured voltage with a light transmitter, a light receiver, and a temperature sensor, and obtaining the measurement signal from the voltage drop or the current of a driving circuit. CONSTITUTION: This measuring device is provided with a device having a light transmitter 16 for emitting light into the blood of an organism and a light receiver 17 for receiving the light reflected by the blood for forming the signal quantity corresponding to the blood oxygen content, a temperature sensor 18 for forming the signal quantity corresponding to the blood temperature, and a driving circuit 7 generating a constant measured current or a constant measured voltage. The light transmitter 16, light receiver 17, and temperature sensor 18 form a two-terminal network feeding the measured current or dropping the measured voltage. The measurement signal is obtained from the voltage drop in the driving circuit 7 or the current outputted from the driving circuit 7.
