Abstract

Inventia se refera la un traductor pentru zgomotul Korotkov, utilizat în aparatele de masurat tensiunea arteriala. Traductorul, conform inventiei, foloseste o sursa de aer, un regulator de presiune care mentine o presiune constanta în circuitul format dintr-un stereoscop si un traductor pneumo-electric care este constituit dintr-o membrana aflata în echilibru static într-o incinta, acest echilibru static fiind asigurat de un robinet reglabil, membrana actionînd asupra unui traductor de presiune dinamica, în sine cunoscut, la iesirea caruia se obtine un semnal electric proportional cu zgomotul Korotkov produs de artera.The invention relates to a Korotkov noise transducer, used in blood pressure measuring devices. According to the invention, the transducer uses an air source, a pressure regulator that maintains constant pressure in the circuit formed by a stereo and a pneumoelectric transducer consisting of a stackable membrane in an enclosure, this static equilibrium is provided by an adjustable valve, the membrane acting on a dynamic pressure transducer, known per se, at the output of which an electrical signal is obtained in proportion to the Korotkov noise produced by the artery.
