Patent number: 11089992Abstract: The invention concerns fetal movement monitoring apparatus having a deflection sensor device arranged to be applied to a mother's abdomen for detection of abdominal deflections indicative of fetal movements and to output a signal comprising one or more record of said abdominal deflections. A processor under the control of machine readable instructions is arranged to process the signal output from the deflection sensor device and to output a log of fetal movement over time. The processor is arranged to receive one or more further input indicative of maternal or fetal movement or wellbeing, for example from a second sensor device by which a user can input a record of perceived fetal movements. The processor may compare the output of the first sensor device and the user's input via the second sensor device and output a log of fetal movements over time based upon said comparison.Type: GrantFiled: April 2, 2014Date of Patent: August 17, 2021Assignee: Monica Healthcare LimitedInventors: Barrie Hayes-Gill, Jean Francois Pieri

Patent number: 9968291Abstract: An apparatus and method for detecting uterine activity uses cutaneous electrodes on the maternal abdomen to obtain electrophysiological signals that can be used to obtain fetal and maternal heart rate. The apparatus includes a first input for receiving electrical signals from the cutaneous electrodes and a second input for receiving movement signals indicative of a movement of the maternal body from a movement detector. A signal processor separates a uterine electromyogram signal from fetal and maternal heart rate signals and filters out motion artifacts from the electromyogram using the movement signals. An output presents electrohysterogram (EHG) data from the uterine electromyogram signal.Type: GrantFiled: July 6, 2010Date of Patent: May 15, 2018Assignee: MONICA HEALTHCARE LIMITEDInventors: Barrie Robert Hayes-Gill, Jean-Francois Pieri

Patent number: 8229550Abstract: Fetal behavior is monitored by receiving ECG data from a set of electrodes attached to a material body. A waveform pre-processor identifies a succession of fetal ECG complex waveforms within the received data and a waveform processor determines differences in the processor succession of fetal ECG complex waveforms over time. An event logger determines from the determined differences a number of fetal movements during the period of time. Fetal spatial presentation and/or position within the uterus may also be determined from fetal ECG data acquired from a plurality of electrodes positioned on the maternal abdomen in a predetermined configuration. A number of fetal ECG complex waveforms are identified within the data, and each of the waveforms is compared with a set of predetermined fetal ECG complex templates ascribed to the predetermined electrode configuration to determine a template that best matches the identified fetal ECG waveforms.Type: GrantFiled: August 21, 2008Date of Patent: July 24, 2012Assignee: Monica Healthcare LimitedInventors: David Keith James, John Andrew Crowe, Barrie Robert Hayes-Gill, Carl William Barratt, Jean-Francois Pieri
