Embodiment Construction

[0031] This disclosure describes a wireless and non-invasive system that combines different fetal monitoring sensors in a single small device that can be worn anywhere without a doctor and does not require bulky medical equipment. Advantageously, the device is comfortably and stably adhered to the patient by a removable pressure sensitive adhesive. The device may further include circuitry to wirelessly send data recorded by the wearable device to a smartphone, computer or central server whereby the patient's doctor, family or others can be alerted of significant events occurring during the woman's pregnancy. Warnings such as impending labor, fetal health, and fetal distress can be integrated into a non-invasive, wireless wearable device.

[0032] refer to Figure 1A -B and figure 2 , embodiments of the present disclosure provide a wearable system that acquires uterine EMG signals or Doppler ultrasound of a pregnant woman and measures fetal heart rate in a single component. ...

Abstract

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 the 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 §119(e) to US Application No. 61 / 863,816, filed August 8, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to systems, devices and methods of uterine contractions and fetal heart rate (FHR) monitoring in pregnancy to assess fetal health and indicate labor onset, and related applications. Background technique [0004] Monitoring women in late pregnancy to predict labor and delivery is an important part of pregnancy management that is safe for mother and child. Currently, a common method doctors use to predict when labor is imminent is the external tocodynamometer. Tocodynamometers are non-invasive devices that resemble large elastic bands that wrap around a pregnant woman's abdomen and measure the frequency of uterine contractions through strain-pressure transducers. A tocometer consists of instruments tha...
