DEVICE FOR ESTIMATING CARDIORESPIRATORY SYSTEM FUNCTIONING

摘要

FIELD: medical engineering. SUBSTANCE: device has casing 1 made from dielectric material and divided in longitudinal direction by means of one-piece partition into two parts. A part of casing 1 on the side of calculation plates along a circle at least two teeth long is made closed in the direction of rotation of cylinder 2 at the half of casing for exhaled air and in the counterrotation direction of cylinder 2 in the other part of casing for inhaled air. Calculation and switch plates for breathing in and out are installed inside casing 1. Transducers 23 for examining exhaled gases are mounted in exhalation cylinder near teeth and do not protrude beyond the teeth plane. Mouthpiece 11 is manufactured from conducting material and is connected with interval cardiogram unit through terminal 10 on casing 1. EFFECT: enhanced effectiveness in analyzing human cardiac and respiratory system. 1 dwg
