Abstract

FIELD: medicine, obstetrics, specifically, perinatology. SUBSTANCE: apparatus comprises piezoelectric elements placed onto anteroventral paries of pregnant woman to emit probing ultrasonic pulses and to detect signals reflected from tissues of mother and fetus. From signals thus-detected is isolated Doppler shift frequency originated only by movements of fetus' heart walls. Apparatus comprises two additional converters adapted to convert 200-600 Hz frequency range signals to signals within frequency range from 16 kHz to 50 Hz. Introduction of 2 additional converters enables apparatus to detect signals which remain out of detection range by any conventional equipment (for instance, at earlier pregnancy terms, starting from 7 weeks, in women suffering from obesity), and to improve other technical parameters of apparatus, namely: to reduce weight, overall dimensions, consumed power, while increasing its sensitivity and resolution power. EFFECT: invention is particularly useful in perinatology, one of obstetrics branches,, for diagnostic purposes by listening to fetus' heart beat and by ferus' cardiomonitoring.

Используется в медицине, а конкретно в перинатологии, одном из отделов акушерства, и предназначено для выслушивания сердцебиения плода, кардиомониторинга плода в диагностических целях. Сущность: устройство для определения состояния плода путем прослушивания его сердцибиения включает в себя пьезоэлектрические элементы, устанавливаемые на переднюю брюшную стенку беременной женщины, излучающий зондирующие ультразвуковые импульсы и принимающий отраженные сигналы от тканей матери и плода, из которых затем выделяется частота доплеровского смещения от движения только стенок сердца плода. В устройство введены два дополнительных блока, в которых эти сигналы преобразуются из области частот 200 - 600 Гц в область от 16 кГц до 50 Гц. Эти блоки позволяют устройству улавливать более слабые, чем известными устройствами, сигналы (например более ранних сроках беременности, начиная с 7 недель, у женщин, страдающих ожирением), а также улучшить другие технические характеристики прибора а именно: уменьшить массу, габариты, потребляемую мощность устройства при его больших чувствительности и разрешающей способности.It is used in medicine, and specifically in perinatology, one of the obstetrics departments, and is intended for listening to the fetal heartbeat, fetal cardiomonitoring for diagnostic purposes. Essence: a device for determining the state of the fetus by listening to its heartbeat includes piezoelectric elements mounted on the front abdominal wall of a pregnant woman, emitting sounding ultrasonic pulses and receiving reflected signals from mother and fetal tissues, from which then the Doppler frequency of movement from only the walls is extracted fetal heart. Two additional blocks are introduced into the device, in which these signals are converted from the frequency range 200 - 600 Hz to the region from 16 kHz to 50 Hz. These blocks allow the device to pick up weaker signals than known devices (for example, earlier pregnancy, starting from 7 weeks in obese women), as well as improve other technical characteristics of the device, namely: reduce the weight, size, and power consumption of the device with its great sensitivity and resolution.
