WIRELESS PREGNANCY MONITOR

摘要

A apparatus for automatically detecting a pregnancy status of a patient include a patch for adhering to human skin, a uterine contraction sensor, such as electromyography (EMG), coupled to the patch with at least two electrodes, and an inertial sensor for sensing fetal movement, or Fetal Heart Rate (FHR) sensor, such as Fetal EKG or a Doppler Ultrasound. An electronic circuit is coupled to the patch, the EMG sensor and the inertial sensor, and/or FHR sensor. The circuit provides an output based on a uterine contraction signal from the EMG sensor (or Doppler ultrasound) correlated in time to a fetal movement, and/or fetal heart rate. The apparatus may include a thermometer to aid in automatically providing an indication of a pregnancy complication or ovulation status of the patient, based on the output.

主权项

1. An apparatus for automatically detecting a pregnancy status of a patient, the apparatus comprising:
a patch of material having a proximal side configured for adhering to human skin and a distal side opposite to the proximal side; an electromyography (EMG) sensor coupled to the patch of material, the EMG sensor comprising at least two electrodes disposed towards the proximal side of the patch of material; a fetal heart rate (FHR) sensor coupled to the patch of material and configured for detecting a fetal heart rate signal when the proximal side is adhered to skin of a patient; and an electronic circuit coupled to the patch of material, coupled to the EMG sensor and to the FHR sensor, and configured for providing an output based on an EMG signal from the EMG sensor correlated in time to an FHR signal from the FHR sensor.
