A system for non-invasively acquiring maternal and/or fetal biopotential signals includes a wearable device configured to be worn by a pregnant patient comprising a plurality of electrodes configured to detect maternal and/or fetal biopotential signals associated with the patient and her fetus. The system further includes a computing device configured to receive the maternal and/or fetal biopotential signals from each of a plurality of electrode pairs and select, based on processing the maternal and/or fetal biopotential signals, one of the plurality of electrodes to use as a reference electrode during a monitoring session for the patient.

Methods for monitoring a fetus employ a mobile computing device. A method of monitoring a fetus includes generating a first preprocessed acoustic signal via amplification of a first acoustic signal. The first preprocessed acoustic signal is processed by a mobile computing device to extract one or more of a fetal heart sound, a fetal heartbeat rate, or a fetal heartbeat acoustic intensity.

A system and apparatus for implementing a user interface for displaying uterine contraction information is provided. The graphical user interface displays first information conveying a rate of uterine contractions, the first information being derived at least in part on the basis of at least a portion of a contraction signal. The graphical user interface also displays, concurrently with the first information, second information conveying a threshold rate of uterine contractions. In specific examples of implementation, the graphical user interface is adapted for selectively causing an alarm event based at least in part on a rate of uterine contractions conveyed by the first information and the threshold rate of uterine contractions.

The present invention relates to a pregnancy monitoring system, the system comprising a fetal monitoring transducer (20) arranged to detect fetal medical condition information; and a control device (48) comprising a motion assessment unit (50) and a signal output unit (52); wherein the fetal monitoring transducer (20) is arranged to detect fetal movement indicative information, wherein the motion assessment unit (50) is arranged to process fetal movement grading information, in addition to the fetal movement indicative information, wherein the signal output unit (52) is arranged to simultaneously output a fetal condition signal, particularly a fetal heart rate signal, and an augmented fetal movement signal based on the fetal movement indicative information and the fetal movement grading information, wherein a characteristic property of the original fetal movement information is still present in the augmented fetal movement signal. The disclosure further relates to a corresponding pregnancy monitoring method.

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.

Systems, methods, and computer-readable media are provided for displaying on a user display device alarm-triggering events detected by the medical device based on the location of the user display device. The method comprises receiving alarm-triggering patient data from a medical device and determining the physical location of first and second user display devices. The method further comprises determining that the physical location of the first user display device is designated to have an alarm displayed, and that the physical location of the second user display device is not designated to have an alarm displayed. In response to these determinations, the content of the alarm is displayed on the first user display device.

Systems and methods for monitoring the onset or occurrence of labor contractions and detecting or estimating labor in a pregnant female are provided.

The present invention relates to a pregnancy monitoring system (10) and to a method for detecting medical condition information from a pregnant subject of interest (12). The system (10) comprises a fetal monitoring transducer (20) that detects fetal medical condition information, a first motion sensor unit (30) associated with the fetal monitoring transducer (20), the first motion sensor unit (30) comprising at least one first motion sensor (70, 72), a second motion sensor unit (32) comprising at least one second motion sensor (70, 72), and a control device (48) comprising an evaluation unit (50) that determines relative motion between the first motion sensor unit (30) and the second motion sensor unit (32), wherein the control device (48) selectively permits, in an enablement mode, processing of the detected fetal medical condition information when a level of relative motion between the first motion sensor unit (30) and the second motion sensor unit (32) indicates stable measurement conditions, and wherein the control device (48) selectively prevents, in a suppression mode, processing of the detected fetal medical condition information when the level of relative motion between the first motion sensor unit (30) and the second motion sensor unit (32) indicates unstable measurement conditions.
