Abstract

A wearable analyte breath alert device and method for non-invasive monitoring of an analyte in a sample from a user. The device comprises an outer casing, a forward face having an in-line insignia, a front port and an activation button, a rear face having a detector threshold region, a side port and a LED indicator, a reversible core having a main processor module and a volatile organic compound (VOC) sensor adaptable to detect at least one volatile organic compound of the user. The VOC sensor further comprises a central sensor circuit having at least one nano gas sensor, a sensor signal conditioning unit and an A/D interface. The central sensor circuit is operably connected to a Bluetooth Low Energy (BLE) element having a microcontroller. An alarm component is coupled with the BLE element that alerts the user based on the analyte detected by the nano gas sensor.

First claim

What is claimed is:

1. A method for detecting volatile organic compounds in a wearable analyte breath alert device for non-invasive monitoring of an analyte in a sample of aerosolized gas from a user, the method comprising:
providing the breath alert device comprising an outer casing, a forward face secured to the outer casing, the forward face having an in-line insignia and at least one front port, the at least one front port adapted to function as a gas sensing port or an evacuation port for evacuating a previous sample, wherein the breath alert device further comprises a rear face opposite the forward face and secured to the outer casing, the rear face having a detector threshold region, a side port and a tri-color light emitting diode (LED), the detector threshold region including a plurality of circular holes configured to function as gas sensor intake ports, speaker ports, and/or sample evacuation ports, wherein the breath alert device further comprises a reversible core positioned in between the outer casing, the forward face and the rear face, the reversible core having a main processor module, and wherein the breath alert device further comprises a volatile organic compound (VOC) sensor adapted to detect at least one volatile organic compound of the user, the VOC sensor positioned on the main processor module, the VOC sensor further comprising:
a central sensor circuit operably connected to a wireless communication element having a microcontroller, the central sensor circuit including a gas sensor unit having at least one nano gas sensor and at least one heater, a conditioning circuit for conversion and gain conditioning, and an A/D interface having an analog to digital converter and a digital to analog converter;
an alarm component having an audio piezo actuator and the tri-color light emitting diode (LED); and
a DC to DC element having a battery charger and a battery;

contacting the sample of aerosolized gas with the VOC sensor through the at least one front port and the detector threshold region, the at least one nano gas sensor of the VOC sensor detecting the analyte in the sample and generating a signal which is directly correlated to the amount of the analyte in the sample;
transmitting the signal to the microcontroller which analyzes the signal to produce a result for the analyte amount; and
alerting via the alarm component the user based on the result from the microcontroller.

2. The method of claim 1 wherein the analyte is selected from the group consisting of: glucose, acetone, and ketones.

3. The method of claim 1 wherein the breath alert device further comprises an activation button that provides an interface with the VOC sensor circuit, permitting the user to set high glucose and low glucose alert levels and set alert types.

4. The method of claim 1 wherein the tri color light emitting diode (LED) includes colored lights configured to indicate low battery, high glucose level, low glucose level, battery charging, and pairing.

5. The method of claim 1 wherein the at least one nano gas sensor is configured to detect glucose, acetone, and ketones.

6. The method of claim 1 wherein the alerting step alerts the user in at least one way selected from the group consisting of: LED light, a programmable voice alert, and an alert to a smart device via the wireless communication element.

7. The method of claim 1 wherein the wireless communication element activates the alarm component based on the signal generated by the central sensor circuit, when the at least one nano gas sensor detects the analyte in the sample.
