The present disclosure relates to a maternal monitoring transducer (20), comprising a housing (60), a substrate board (72), particularly a PCB (70), disposed in the housing (60) and comprising control components (74), and a displacement measurement arrangement (76) comprising a displacement-sensitive structure (78) that is arranged to detect deformations of a deflectable measurement section (80) of the substrate board (72), wherein the maternal monitoring transducer (20) supplies a signal that is representative of maternal motion. The disclosure further relates to a method of operating a maternal monitoring transducer (20).

A system for sensing physiological traits of a maternal patient and a fetal patient carried by the maternal patient during a pregnancy using one or more sensors. The system may use the physiological traits sensed to define a maternal attribute for the maternal patient and a fetal attribute for the fetal patient, such as a heart rate, blood pressure, respiration rate, temperature, oxygen saturation level, or other attributes. The system is configured to compare the maternal attribute to a maternal limit describing a threshold for the maternal patient and/or compare the fetal attribute to a fetal limit describing a threshold for the fetal patient. The system is configured to issue a communication to the maternal patient and/or a clinician based on the comparisons. In examples, the system regularly communicates the maternal attribute and/or the fetal attribute to an output device of the maternal patient and/or a clinician.

A computing device arrangement (20) for receiving fetal monitoring data from a fetal monitoring system is disclosed. The computing device arrangement comprises a display device (30) arranged to display the fetal monitoring data, a touchscreen device (32) and a processor arrangement (24) communicatively coupled to the display device and the touchscreen device. The processor arrangement is arranged to receive the fetal monitoring data from the fetal monitoring system, control the display device to display the fetal monitoring data, receive a freeform input (36) in a region of the touchscreen device from the touchscreen device; modify the fetal monitoring data by annotating a displayed region (34) of the fetal monitoring data with the freeform input, said displayed region corresponding to the region of the touchscreen device; and generate an output of the modified fetal monitoring data for storage in a data storage device (28). Also disclosed are a fetal monitoring system including such a computing device arrangement and a method of generating freeform annotations with such a computing device arrangement.

Provided is a biological information detection device capable of restraining noise from being mixed with a signal relating to biological information. A biological information detection device includes an electrode pad that is able to detect a signal (bioelectric signal) relating to biological information of a subject (for example, a fetus in a mother's body), a connector that is connectable to the electrode pad, and a cable that is connected to the connector and is able to transmit the signal. The electrode pad and the connector are provided with fixing members and that are attachable to and detachable from each other, respectively.

A system obtains a maternal electrocardiogram (ECG) signal that represents an ECG of a pregnant mother during a first time interval. The system further obtains a mixed maternal-fetal ECG signal that represents a combined ECG of the mother and her fetus during the first time interval; processes the maternal ECG signal and the mixed maternal-fetal ECG signal to generate a fetal ECG signal that represents the ECG of the fetus during the time interval, the fetal ECG signal substantially excluding the maternal ECG signal; and provides an output based on the fetal ECG signal.

A system for monitoring the fetal size of an expectant mother comprises an acoustic sensor for positioning over the belly of the expectant mother, the acoustic sensor configured to receive an acoustic signal generated by the fetal heartbeat and to generate a sensor output signal. A fetal size is determined from a sensor output signal strength. This system is based on the realization that certain acoustic signals generated by the fetal heart beat are strongly correlated with the fetus size.

Apparatus and methods for monitoring pregnancy or labour are disclosed. In one embodiment the apparatus includes an electromyography (EMG) sensor having two or more EMG electrodes to monitor fetal or maternal activity during pregnancy or labour and one or more position sensors to monitor the relative positioning of the two or more EMG electrodes during the fetal or maternal activity. In one embodiment, the apparatus includes a monitoring device to be placed on a body and having a plurality of sensors integrated into the monitoring device, the plurality of sensors including at least: a first sensor configured to detect a first type of signal from the body indicative of a first type of fetal or maternal activity during pregnancy or labour; and a second sensor configured to detect a second type of signal from the body, different from the first type of signal, also indicative of the first type of fetal or maternal activity during pregnancy or labour.

The present invention relates to methods for diagnosing Respiratory Distress Syndrome of newborn.

During childbirth process, trauma to an infant can readily arise, ultimately resulting in fetal hypoxia, academia, and brain damage. Such unfavorable conditions can be prevented by measuring the fetus' blood-oxygen level and heart rate. Without a fetal pulse oximeters, blood oxygen level cannot be monitored non-invasively reliably, which reduces the chance for birth complications to be recognized in time. A noninvasive system to implement such goals and maximize the potential welfare of the fetus may include devices to measure oxygen saturation of hemoglobin (SpO2) that have been available for at least 50 years. Such a device may be an oxy probe that uses a trans-reflective method of SpO2 measurement where oxygen saturation data can be transmitted through wire, fiber optics, and or using a radio frequency link, fetal monitor data can be analyzed, compared to existing data base, and or transmitted via radio waves or internet.

An apparatus has a computer receiving input signals indicative of fetal heart rate (“FHR”) and maternal uterine activity in a patient. The computer determines when each of FHR, baseline FHR variability, FHR accelerations, FHR decelerations, and maternal uterine activity exhibit a plurality of pre-defined non-reassuring characteristics. The computer receives inputs indicating the presence of maternal, obstetrical, and fetal risk factors, and determines at predetermined times during labor a present level of risk to the fetus which accounts for the total of the number of parameters that each exhibit the non-reassuring characteristics at predetermined points in time during labor and the number of risk factors present. An output display depicts in a single graphical interface information respecting the parameters and risk factors over time during labor. The graphical interface includes indicia for indicating the present level of fetal risk at the predetermined times during labor and signals the need for intervention.
