A seamless, smart fetal monitoring garment and methods of using thereof. The system includes a knitted or interwoven garment having a multiplicity of conductive textile electrodes for sensing maternal and fetal electrical vital signals. The maternal and fetal electrical vital signals are selected from a group including maternal heart rate, fetal heart rate and electromyogram (EMG) activities including uterine activities. The method includes wearing the garment, acquiring electrical mixed common, maternal and fetal vital signals from surface region of a pregnant woman, using the plurality of textile electrodes, optimally weighted summing-up the acquired signals, analyzing the summed-up signals to thereby extract the maternal signal and the fetal signal, including determining their heart rates, and including detecting health hazards and in some embodiments, including detecting a uterine contraction sequence suggesting the need to be hospitalized for birth giving.

Light reflected from a pregnant woman's abdomen and fetus contained therein that has been received by a detector and converted into a reflected electronic signal may be received by a processor. A portion of the reflected electronic signal that is reflected from the fetus may be isolated and the isolated portion of the reflected electronic signal may be analyzed to determine a fetal hemoglobin oxygen saturation level of the fetus. The isolation may be achieved by synchronizing the reflected electronic signal with a fetal heartbeat signal and multiplying the synchronized reflected electronic signal by the synchronized fetal heartbeat signal.

A system for the assessment and monitoring of the fetal electrocardiogram (ECG) and heart rate in a pregnant mother comprises wearable mechanical-electronic sensors, e.g., embedded in a wrist or arm band, which can measure the mechanical pulse signals from the mother, and an abdomen patch which can measure the combined ECG signals of the fetus and mother. The wrist or arm unit and the abdominal patch unit communicate wirelessly. By signal processing and gating out the maternal ECG signals as correlated with the mechanical maternal pulse signals, the fetal ECG and heart rate can be measured and monitored. These measurements may be displayed on the wrist or arm band device, or wirelessly through a remote device, mobile phone or computer. Electronic-mechanical sensors can also be embedded in the abdominal patch to measure uterine electromyogram (EMG), uterine contractions and fetal movements, to be correlated with the fetal ECG.

The invention relates to a method and device for locating wireless fetal monitoring probes in a set area. The method comprises the following steps: instructions are sent via a plurality of wireless base stations to instruct the wireless probes in the action scopes of the wireless base stations to send base station signal intensity data tables; the wireless probes search all receivable base station signals, establish the base station signal intensity data tables; operations are carried out based on the received current base station signal intensity data tables and base station signal intensity data tables of reference points to obtain a distance reference table; the position of one with the smallest distance value is selected to be regarded as the current position of the corresponding probe. The method and the device have the benefits of quickly locating each wireless probe and avoiding loss of monitoring data.

A wearable maternity article is provided. The article may comprise a front portion, a back portion substantially opposite to the front portion, a side portion in between the front portion and the back portion, an interior portion, an exterior portion opposite to the interior portion, at least one pocket, wherein at least one pocket is positioned substantially on the back portion, and at least an insert.

A portion of the reflected electronic signal that is reflected from the fetus may be isolated and the isolated portion of the reflected electronic signal may be analyzed to determine a fetal hemoglobin oxygen saturation level of the fetus. The isolation may be achieved by synchronizing the reflected electronic signal with a fetal heartbeat signal and multiplying the synchronized reflected electronic signal by the synchronized fetal heartbeat signal.

A method for obtaining fetal heart rate which includes: transmitting an ultrasonic pulse wave towards an abdomen of a pregnant woman according to a preset period; receiving a pulse echo and a fetal heart echo corresponding to the ultrasonic pulse wave in each period, and processing the pulse echo and the fetal heart echo independently to obtain a corresponding pulse rate of the pregnant woman and the fatal heart rate; outputting the fetal heart rate when a difference value between the fetal heart rate and the pulse rate of the pregnant woman is not lower than a preset threshold. Furthermore, a system and an apparatus for obtaining fetal heart rate are also provided. The method and terminal for obtaining a fetal heart rate improves accuracy of the obtained fetal heart rate.
