Clinical instrument for measuring pulse rate and body temperature

摘要

A clinical instrument using a thermocouple probe for the measurement of pulse rate and body temperature using a single sensor. The variation in temperature due to heart beat found at the base of the tongue is detected with a fine wire thermocouple and timed. Pulse rate is calculated and displayed based on the time between beats. The DC component of the thermocouple output is digitized and displayed as body temperature.
