Breath analysis system with measurement tagging interface
A portable system is provided for measuring an analyte, such as acetone, in the breath or other bodily fluid of a user. The system includes a portable measurement device that analyzes fluid samples and generates corresponding measurements. The portable measurement device communicates with an application which runs on a smartphone or other mobile device of the user. The application tracks, and generates graphs of, the measurements, and may include various features for facilitating the analysis of the measurements.
1. A breath analysis system comprising:
a breath analysis device comprising a breath input port, an analyte sensor, and a wireless transceiver, the breath analysis device configured to generate breath analyte measurements representing breath analyte levels in breath samples of a user, the breath analysis device further configured to transmit the breath analyte measurements to a mobile device of the user; and
a mobile application configured to run on the mobile device, the mobile application including a measurement tagging user interface that displays a set of tags, each tag representing a respective condition that can affect analyte measurements, each tag being individually selectable via the measurement tagging user interface to tag an analyte measurement received from the breath analysis device with information that enables masking effects of the conditions to be considered during subsequent analysis of analyte measurements.
2. The breath analysis system of claim 1 , wherein the set of tags is personalized for the user.
3. The breath analysis system of claim 1 , wherein the mobile application includes a second user interface that enables the user to select, from a master set of tags, said set of tags displayed by the measurement tagging user interface.
4. The breath analysis system of claim 1 , wherein the set of tags includes a tag representing consumption of food within a defined time period of taking an analyte measurement.
5. The breath analysis system of claim 1 , wherein the set of tags includes a tag representing intake of a medication within a defined time period of taking an analyte measurement.
6. The breath analysis system of claim 1 , wherein the set of tags includes a tag representing an exercise activity.
7. The breath analysis system of claim 1 , wherein the set of tags includes a tag representing a user stress condition.
8. The breath analysis system of claim 1 , wherein the mobile application is configured to display a plurality of tag-specific graphs, each of which corresponds to a different respective tag of said set of tags, each tag-specific graph based on analyte measurements tagged with the respective tag.
9. The breath analysis system of claim 1 , wherein the breath analysis device is configured to receive a disposable cartridge comprising an interactant that reacts with the analyte.
10. The breath analysis system of claim 1 , wherein the analyte is acetone.
11. The breath analysis system of claim 1 , wherein the analyte sensor is a nanoparticle sensor.
12. A method, comprising:
generating an analyte measurement with a breath analysis device that comprises a breath input port, an analyte sensor and a wireless transceiver, the analyte measurement representing an analyte level in a breath sample;
wirelessly transmitting the analyte measurement to a mobile device with the wireless transceiver of the breath analysis device; and
by execution of a mobile application on the mobile device:
displaying, in association with the analyte measurement, a tagging interface that includes a set of tags, each tag representing a respective condition that can affect analyte measurements, each tag being selectable via the tagging interface to associate the tag with the analyte measurement;
receiving, via the tagging interface, a user selection of a tag to associate with the analyte measurement; and
recording the selection of the tag in association with the analyte measurement.
13. The method of claim 12 , wherein the set of tags is personalized for a particular user.
14. The method of claim 13 , further comprising, prior to generating the analyte measurement, receiving user input defining the personalized set of tags, wherein the user input comprises a selection of a subset of a master set of tags, the subset including multiple tags and omitting at least some tags in the master set.
15. The method of claim 12 , further comprising, by execution of the mobile application on the mobile device, displaying the analyte measurement in a tag-specific graph corresponding to the tag.
16. The method of claim 12 , wherein generating the analyte measurement comprises detecting, by a sensor, a color change produced by a chemical reaction in a disposable cartridge.
17. The method of claim 12 , wherein the analyte measurement is generated with a nanoparticle sensor.
18. The method of claim 12 , wherein the set of tags includes a tag representing consumption of food within a defined time period.
19. The method of claim 12 , wherein the set of tags includes a tag representing intake of a medication within a defined time period.
