[0001] Fetal monitoring device and method [0002]

The present invention relates to a maternal and fetal monitoring technique, and more particularly, to an ultrasonic probe for a fetal monitoring apparatus, which detects vibrations generated in a loudspeaker to detect fetal heart rate FHR (Fetal Heart Rate) It is about the technical idea to measure.

Maternal and fetal condition monitoring device is a device for diagnosing the condition of mother and fetus by measuring heartbeat or heart sound.

Maternal and fetal surveillance is generally necessary for pregnant women with hypertension, gestational diabetes, and low birth weight, and it is necessary to continuously monitor fetal condition until normal maternal prenatal and anal labor.

Maternal and fetal monitoring devices can be divided into personalized fetal monitoring devices and centralized fetal monitoring devices. The personalized fetal monitoring device detects fetal heart rate and fetal movements from the mother using fetal heartbeat detection means, displays it in a digital value and graph, and judges the health condition of the fetus by a user in a complex comparison. In the case of a personal fetus monitor, general mothers are inconvenient to use because they lack medical knowledge. The centralized fetal monitoring system centrally monitors and controls several personal fetal monitoring devices. It simultaneously displays data such as the fetal heart rate transmitted from each fetal fetal monitoring device, so that it can manage a large number of mothers have. Fetal heart rate testing, especially fetal heart rate testing, has an important place in the evaluation of prenatal fetal status and should be measured accurately.
