Systems and methods of maternal and fetal monitoring include acquiring ultrasound physiological data with an ultrasound transducer. A plurality of electrodes acquire biopotential physiological data from the skin of a patient. A controller receives the ultrasound and biopotential physiological data and calculates fetal heart rate (fHR) values, maternal heart rate (mHR) values, and uterine activity (UA) values from the ultrasound and biopotential physiological data.

A garment shaped to approximate the abdomen of an expectant mother having a layered laminated conductive material adhered to the garment is disclosed. A portion of the laminated material is configured to directly contact the skin of the maternal abdomen to create an electrical signal connection. A portion of the layered laminated material comprises a stretchable circuit assembly having a substrate with an adhesive layer, a thermoplastic layer, a conductive layer and an encapsulating layer. A monitor controller is disposed about the garment and is configured to receive electrical signals from the circuit assembly and transmit information related to the electrical signals to a remote location.

An apparatus for monitoring an obstetrics patient during labour is provided. The apparatus receives a contraction signal conveying information related to occurrences of uterine contractions over time and processes his signal to derive a sequence of rates of uterine contractions over time. The apparatus also implements a Graphical User Interface (GUI) presenting a tracing of at least part of the sequence of rates of uterine contractions over time along with a threshold rate of uterine contractions GUI is dynamically adapted over time based on the contraction signal received. The sequence of rates of uterine contractions derived over time is also processed to detect occurrences of anomalous contraction rates and to identify one or more portions of the tracing corresponding to sustained anomalous contraction rate segments during which anomalous contraction rates have persisted for time durations exceeding a pre-determined time duration. The GUI is configured to trigger an alarm event in response to identification of a specific sustained anomalous contraction rate segment.

Fracture-induced composite sensors and methods of their fabrication are disclosed. The sensors can be used as strain sensors, piezo-resistive sensors, piezo-capacitive sensors, and non-contact displacement wearable sensors.

A computer-implemented method includes: monitoring, by a computing device, exposed stimuli based on sensor data; monitoring, by the computing device, a response to the stimuli based on the sensor data; detecting, by the computing device, a deviation between the response to the stimuli and an expected response to the stimuli, wherein the expected response to the stimuli is determined based on information stored by a knowledge corpus; and executing, by the computing device, a deviation instruction based on the detecting the deviation.

A sensor interface system for providing a connection between at least one sensor and a maternal-fetal monitor, wherein the interface system converts electrical muscle activity captured by the sensor(s) into uterine activity data signals for use by the maternal-fetal monitor. The sensor interface system of the invention preferably includes a conversion means for converting the signals from the sensor(s) into signals similar to those produced by a tocodynamometer.

Provided is a diagnostic device for diagnosing a state of a subject based on a ratio or a difference between a color intensity of a first test portion and a color intensity of a second test portion in a reaction unit receiving a sample therein, wherein reaction unit includes a sample pad; a conjugate pad; a reaction membrane; and a wicking pad, and wherein the reaction membrane has two or more test portions.

There is described a method of reproducing a movement occurring during a pregnancy, the method comprising: determining movement data relating to movements during pregnancy using a sensor device; transmitting the movement data from the sensor device to an external device; storing the movement data on the external device; and transmitting data relating to one or more movements of the movement data from the external device to an output device that is arranged to reproduce the movements, wherein said transmitting occurs substantially after the storing of the movement data; and reproducing the movements using the output device.

The invention provides a fetal movement monitoring system which uses optical pattern sensing to detect fetal movements. Fetal movements provide a change in the optical path between the optical sensor and detector, such as a different proportion of amniotic fluid and fetus and/or a different contact pressure with the optical sensor arrangements. One or both of these effects may be detected based on analysis of the optical signals captured by the system.

A method for obtaining fetal heart rate which includes: transmitting an ultrasonic pulse wave (110) 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 of the periods, and processing the pulse echo and the fetal heart echo independently to obtain a corresponding pulse rate of the pregnant woman and the fetal heart rate (130); outputting the fetal heart rate (150) 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.
