摘要：
The invention provides a system for monitoring a fetus in a pregnant woman and/or the maternal health risk for pregnancies complicated by such as pre eclampsia and hypertensive disorders. The system comprises a portable or wearable unit that can be worn by the pregnant woman preferably so as to allow monitoring during daily life e.g. in the form of an adhesive patch. The portable unit has a sound sensor e.g. a microphone or accelerometer to be positioned on the skin of the abdominal area of the pregnant woman so as to detect a vascular sound from umbilical arteries of the fetus or from the uterine arteries of the pregnant woman. The sound sensor is functionally connected to a processing unit which executes a processing algorithm on the captured vascular sound and extracts a signal parameter accordingly e.g. the Pulsatility Index. The processing unit then communicates the signal parameter e.g. using an audio signal a visual display or by means of a wired or a wireless data signal. Some embodiments include one or more additional sensors such as a sensor for detecting fetal electrocardiographic signals and/or a sensor for detecting uterus electromyographic activity. Especially the sound sensor and such additional sensor(s) may be arranged within one adhesive patchor several adhesive patches.
