System and method for monitoring gastric fullness
View Patent ↗A system for monitoring stomach fullness includes an ultrasound transponder configured to transmit ultrasound signals and receive reflected ultrasound signals. A processor is configured to process the received reflected ultrasound signals to determine level of stomach fullness and output fullness data indicative of the determined level of stomach fullness. A memory stores calibration data representative of calibrated levels of stomach fullness including empty and full. A stored program has executable codes to, upon execution, control the ultrasound transponder, compare the fullness data against the calibration data, and output alert data upon a match of a preset fullness level.
1. A system for monitoring stomach fullness, comprising:
an ultrasound transponder configured to transmit ultrasound signals and receive reflected ultrasound signals;
a processor configured to process the received reflected ultrasound signals to determine a level of stomach fullness and output fullness data indicative of the determined level of stomach fullness, wherein the determined level of stomach fullness is based on identified baseline information corresponding to measurements of a user;
a memory configured to store calibration data representative of a plurality of calibrated levels of stomach fullness including empty and full; and
a stored program having executable codes to, upon execution, control the ultrasound transponder, compare the fullness data against the calibration data, and output alert data upon a match of a preset fullness level.
2. The system of claim 1 , wherein the stored program or the ultrasound transponder are embedded in a smartphone.
3. The system of claim 2 , wherein the smartphone executes the stored program to output the alert data audibly or visually.
4. The system of claim 2 , wherein the smartphone executes the stored program to activate the ultrasound transponder at a preset interval including continuously or upon user activation.
5. The system of claim 1 , wherein at least one of the memory or the stored program is cloud-based and is accessible via wireless communication.
6. The system of claim 1 , further including a wifi configured to establish communication with a portable processing device.
7. The system of claim 6 , wherein the portable processing device is at least one of a smartphone, a smart wearable device, a smart tablet, or a laptop computer.
8. The system of claim 6 , wherein the portable processing device executes the stored program to output the alert data audibly or visually.
9. The system of claim 6 , wherein the portable processing device executes the stored program to activate the ultrasound transponder at a preset interval including continuously or upon user activation.
10. The system of claim 1 , wherein the processor executes the stored program to perform analysis of the fullness data in connection with glucose data received from an external device, wherein a correctness of the glucose data is determined based on the fullness data.
11. The system of claim 1 , wherein the ultrasound transponder is adhered or strapped to a portion of a user's skin proximal to the user's stomach.
12. The system of claim 1 , further including an accelerometer to determine the position of the user and calibrate the determined level of stomach fullness based on the determined position of the user.
13. A method of monitoring stomach fullness, comprising:
identifying baseline information corresponding to measurements of a user;
transmitting ultrasound signals to a stomach of the user;
receiving reflected ultrasound signals;
processing the received reflected ultrasound signals and the baseline information to determine level of stomach fullness;
outputting fullness data indicative of the determined level of stomach fullness; storing calibration data representative of a plurality of calibrated levels of stomach fullness including empty and full;
comparing the fullness data against the calibration data; and
outputting alert data upon a match of a preset fullness level.
14. The method of claim 13 , further including wirelessly transmitting the fullness data to a processing device.
15. The method of claim 14 , further including wirelessly communicating from the processing device a control signal to control transmitting ultrasound signals at a preset interval including continuously or upon user activation.
16. The method of claim 14 , wherein the alert data is audibly or visibly presented at the processing device.
17. The method of claim 13 , wherein the calibration data is stored at a remote cloud-based storage device.
18. The method of claim 13 , wherein the comparing the fullness data against the calibration data is performed at a remote cloud-based processing device.
19. The method of claim 13 , wherein the fullness data is analyzed in connection with glucose data received from an external device, wherein a correctness of the glucose data is determined based on the received reflected ultrasound signals.
20. The method of claim 13 , further including determining position of the user by an accelerometer and calibrate the determined level of stomach fullness based on the determined position of the user.
