Abstract: A computer-implemented method for detecting fetal peaks in a maternal ECG signal includes steps of receiving the maternal ECG signal and preprocessing the maternal ECG signal wherein preprocessing includes removal of mECG R-peaks to form a process ECG signal that includes both fetal and noise peaks. Both fetal and noise peaks are detected using a peak detection algorithm which yields an array of peaks Xk×1. Permutations of all peak differences are calculated by subtracting elements of Xk×1 from its transpose Xk×1T to form a matrix Mk×k. Characteristically, elements in the matrix Mk×k corresponds to different sample periods that are used to determine peak positions. An array of periods denoted an array LP×1 is calculated. A 3-dimensional matrix GP×k×k is constructed by dividing Mk×k by each element of LP×1. An optimal Mk×k is determined by finding the Mk×k in the 3-dimensional matrix GP×k×k that has it's first row with the most elements near a whole number.

Abstract: A system for achieving optimal sensor placement and enhanced signal quality for monitoring maternal and fetal activities is disclosed. The system includes a monitoring device and a computing unit. The monitoring device is configured for monitoring maternal and fetal activities and providing guidance to the user via the computing unit upon detecting a feature of interest. The monitoring device includes a plurality of sensors, a data acquisition and transmission unit, one or more reference electrodes, and a ground electrode. Based on personal data acquired using the computing unit, the system utilizes a statistical or machine learning model which incorporates one or more subsets of the personal data to determine the optimal sensor placement close to the fetal heart position. Following sensor placement, the monitoring device performs a signal quality assessment and selects the optimal sensors to ensure reliable information on maternal and fetal activities is obtained.

Abstract: Proposed are concepts for generating and using a prediction model that enables the prediction of the quality (e.g. accuracy and/or reliability) of an electrode configuration (i.e. arrangement) for electrophysiological measurements. It is proposed to use training data to determine parameter values of a prediction model so that the prediction model is configured to accurately predict a quality value (e.g. measure of accuracy) of an arrangement or pattern of electrodes for electrophysiological measurements of a subject. Embodiments may thus facilitate the assessment of an electrode configuration and/or there commendation of changes to an electrode configuration so as to enable more reliable and/or accurate electrophysiological measurements to be obtained.

Abstract: A fetal Doppler (10) and a detection method, which relate to the technical field of medical devices. The fetal Doppler (10) comprises a housing (1, a fetal detection unit (20) and a maternal parameter detection unit (30), wherein the fetal detection unit (20) and the maternal parameter detection unit (30) are respectively used for collecting fetal physiological data and maternal physiological data; a controller (7) is arranged in an internal cavity of the housing (1); and the controller (7) is used for analyzing the collected fetal physiological data and maternal physiological data, so as to obtain a fetal heart rate and a maternal parameter. The same fetal Doppler (10) is used, such that the instrument cost is reduced; and maternal and fetal parameters can be acquired at the same time by directly using the same fetal Doppler (10), such that an instrument structure is simplified, and the detection efficiency of the maternal and fetal parameters is improved.

Abstract: 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.

Abstract: A method of fetal ultrasound monitoring includes detecting contact of a first ultrasound transducer to a mother's abdomen based on input from a contact sensor in the first ultrasound transducer. A first transducer identifier is received from the first ultrasound transducer, and then the first transducer identifier is correlated with a first transducer label. A first heart rate is measured based on output of an ultrasound device in the first ultrasound transducer, and a heart rate indicator is displayed accordingly. A position of the first ultrasound transducer is identified in a two-dimensional plane, and the first transducer label is displayed on an abdomen image based on the first position.
