摘要：
The present technical solution relates to the field of medical instrumentation, in particular, to devices for ultrasound echolocation internal organs, and can be used in medical diagnostic systems. The technical result provided by the reduced set of features is to improve the diagnosis of fetal development by increasing the accuracy of FHR calculation by automatic positioning and size of the measurement Doppler volume in accordance with the position of the fetal heart depth sensing, the control signals from all sensing depths parameters allows exclude the error detection signal heartbeats and subsequent maintenance of a false signal such as the signal, then zhdaemogo mother aortic blood flow, furthermore by using a digital processor element base high integration is possible to reduce the device size compared to devices allocation FHR using analog elements for the construction of the receive path. Ultrasonic apparatus for measuring fetal heart rate, comprising electrically interconnected block transmission-reception control, a power amplifier, an ultrasonic sensor, an input amplifier, an analog-digital converter and a digital signal processor, which incorporates the quadrature components of the signal generator of the control volume , bandpass filter, an amplitude detector, autocorrelator, shaper fetal heart rate, parameters shaper doplerovskog signal generator responsive strobe receiver that is configured to dynamic correlation of the measured parameters volume, namely its depth by sensing the size and location to provide optimum reception of echo signals from moving tissue fetal heart. 1 n.p.f. 6 z.p.f. 4 yl.Настоящее техническое решение относится к области медицинского приборостроения, в частности, к устройствам для ультразвуковой эхолокации внутренних органов, и может быть использовано в системах медицинской диагностики.
