DESC:FIELD OF THE INVENTION

The present disclosure relates to a wearable fetal movement tracker and alert device. More specifically, a battery-operated wrist-worn wearable tracker, which is used to track the fetal movements by the pregnant mothers and/or to send SOS alerts in case of emergency.

BACKGROUND OF THE INVENTION

The foetus movement tracking involves expectant parents tracking their unborn babies kicks and movements in the womb (uterus). Changes in movement patterns can sometimes indicate the foetus (unborn baby) is under stress. Knowing your baby's normal movement patterns can help you sense when something seems off.

Traditionally, an assessment will be made by a midwife and monitoring of the fetal heart will be undertaken using a cardiotocograph (CTG). The CTG monitors your baby's heart rate continuously over a period of time, usually 20 minutes. Two sensors are strapped to your abdomen (bump) and the readings are printed on paper. Currently mothers are asked to hold a sheet of paper and add a tear every time they feel a movement or they are manually tracking with pen and paper. This doesn’t provide any correlation with the time of the fetal movement.

However, the foetus movement tracking is very expensive and lengthy process that required large cardiography machines. In the view of the forgoing discussion, it is clearly portrayed that there is a need to have a user-friendly wearable fetal movement tracker and alert device to track the fetal movements with ease and track the previous data using the companion application to ensure the fetal is in healthy condition.

SUMMARY OF THE INVENTION

The present disclosure seeks to provide a wearable fetal movement tracker supposed to be worn by pregnant women to track the fetal movements with ease and track the previous data using the companion application to ensure the fetal is in healthy condition. The wearable device also provides haptic and visual feedback to users during the interaction with the device. The wearable can also be used as a SOS button in case of emergency.

In an embodiment, a wearable fetal movement tracker and alert device is disclosed. The device includes a wearable body worn by a user.
The device further includes a touch sensor is connected to the wearable body and configured to detect user interaction and fetal movement.
The device further includes a KEYAR patch detachably coupled to the wearable body, configured to capture fetal movement.
The device further includes a processing unit is connected to the touch sensor to communicate with a user computing device via a communication device and synchronize movement data and timestamps with the user computing device thereby controls operation timing of the device, including wake-up periods and sleep mode upon detecting user interactions.
The device further includes at least one Light Emitting Diode (LED) is positioned on a circumference of a display of the wearable body configured to display different colors based on touch sensor state, including: a blue LED blinking for connection mode, a solid blue LED blinking for 3 seconds after successful connection, a cyan LED blinking in a breathing effect for standby mode, a green LED blinking for 3 seconds upon registering a double tap, a red LED continuously blinking for disconnection, a solid yellow LED blinking for low battery condition, a red LED blinking for charging mode, a solid white LED blinking for fully charged state until a long touch is received.
The device further includes a haptic unit is having a vibration motor coupled to the KEYAR patch and configured to generate haptic feedback based on movement data to alert or notify the wearer.
The device further includes a control unit is configured to generate daily and monthly reports on fetal movement activity within the user computing device..
