摘要：
The utility model relates to medical equipment and can be used to monitor the condition of the fetus during pregnancy and childbirth.A device for accurate registration of the fetal heart rate, consisting of a series-connected ultrasonic sensor with a radiator and a reflected signal receiver mounted on the front wall of the pregnant abdomen, a phase-sensitive rectifier and a high-pass filter, on which, according to a utility model, an amplifier with a gain of 10-20 times is installed, input the amplifier is connected to the output of the high-pass filter, the output of the amplifier is connected to the first input of the resolution block and the first input of the comparison device with signals, the second input of the signal comparison device is connected to the output of the reference memory unit, the output of the comparison device is connected to the second input of the resolution unit, the output of the resolution unit is connected to the input of the interval measurement unit, the first output of the interval measurement unit, on which data on the time intervals between the starting points are generated long pauses, connected to the first input of the diagnostic unit, and the second output of the interval measurement unit, on which data is generated on the duration of the zero sections of the signal, with the second input ohm diagnostic unit.The proposed device allows to solve two problems - accurate measurement of fetal heart rate - to accurately identify the fetal heart by its valves and to determine the beginning of the cardiocycle by a reliable leading edge of the signal with high accuracy, to ensure accurate registration of variations in the frequency (rhythm) of heart contractions and the dynamics of the phases of the fetal heart cycle.Полезная модель относится к медицинской технике и может быть применена для контроля состояния плода во время беременности и родов.Устройство точной регистрации частоты сердцебиения плода, состоящее из последовательно соедин
