DOPPLER ULTRASOUND BASED ON FETAL MONITORING Russian patent published in 2017 - IPC A61B8/08 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical equipment, namely to means of fetal monitoring on the basis of ultrasonic examination. Device for limiting ultrasound radiation to the fetus by ultrasound comprises an estimator unit for estimating an adequacy of acoustic coupling between an ultrasound transducer and the subject bearing the fetus, an accumulator unit for accumulating a time duration, during which the ultrasound is radiated into a subject, based on evaluation, the first comparison unit for comparing the accumulated time duration with a reference time duration, detector unit for detecting a movement of the fetus based on reflected ultrasound radiation, counter unit for counting the number of detected fetal movements, second comparison unit for comparing the number of counted fetal movements with a reference number, decision unit for making a decision based on an output of the first comparator and an output of the second comparator configured with a possibility to make a decision to disable the ultrasound radiation, and a user interface for conveying an information to the subject based on the at least one decision. Method for limiting ultrasound radiation to the fetus is performed by using a machine-readable data carrier.

EFFECT: using the inventions will allow to increase safety rate of ultrasonic examination.
