Pregnancy monitoring system and method

Abstract

The present invention relates to a pregnancy monitoring system, the system comprising a fetal monitoring transducer (20) arranged to detect fetal medical condition information; and a control device (48) comprising a motion assessment unit (50) and a signal output unit (52); wherein the fetal monitoring transducer (20) is arranged to detect fetal movement indicative information, wherein the motion assessment unit (50) is arranged to process fetal movement grading information, in addition to the fetal movement indicative information, wherein the signal output unit (52) is arranged to simultaneously output a fetal condition signal, particularly a fetal heart rate signal, and an augmented fetal movement signal based on the fetal movement indicative information and the fetal movement grading information, wherein a characteristic property of the original fetal movement information is still present in the augmented fetal movement signal. The disclosure further relates to a corresponding pregnancy monitoring method.

AI Technical Summary

Benefits of technology

The present invention provides a pregnancy monitoring system and method that can improve accuracy and reliability. It is less susceptible to motion-related mismeasures, making it suitable for monitoring under external motion-afflicated conditions. The system is widely accepted by medical staff and does not pose major adaptive challenges. It can be operated with little or no adaption or readjustment of clinical practice, assuming the medical staff is used to a certain type of common pregnancy monitoring systems. The informative content is greatly enriched, but still clear and manageable.

Problems solved by technology

As a result, fetal movement detections are usually only reliable when there are no motion artifacts.

Fetal movements may be rather complex, particularly in terms of their impact on the Doppler signal.

As discussed in WO 2015 / 062851 A1, further non-indicative movements may cause a distortion of the fetal motion signal or even cause incorrect fetal movements indications.

As a result, also the binary fetal movement indication may be afflicted with false indications.
