Photoelectric pulsation type pulsimeter
First Claim
1. A photoelectric pulsation type pulsimeter comprising:
- a pulsation detection circuit for detecting a pulsation pulse of a heartbeat and outputting a pulsation signal to pulse width evaluation means;
pulse width evaluation means for evaluating said pulsation signal and a pulse rate;
pulsation calculation means for calculating said pulse rate;
a reference signal generation circuit for generating a reference signal and outputting said reference signal to said pulsation calculation means and said pulse width evaluation means; and
display means for displaying said pulse rate calculated by said pulsation calculation means.

Abstract
A photoelectric pulsation type pulsimeter irradiates the ray of light to a capillary blood vessel of a finger tip or the like and detects the level of the reflected ray of light changing with the pulsation as the pulsation. The present invention improves stability of the pulse rate display by disposing pulse width evaluation means between a pulsation detection circuit for detecting the pulsation and pulsation calculation means for measuring the period of the pulsation signal and calculating the pulse rate per minute.
The pulse width evaluation means evaluate the pulse signal outputted from the pulsation detection circuit and the pulse rate calculated by the pulsation calculation means.
