Ketone measurement system and related method with accuracy and reporting enhancement features

摘要

A portable ketone measurement device measures ketone levels in breath samples or other bodily fluid samples of a user, and communicates the ketone measurements to an application that runs on a smartphone or other mobile device of the user. The application may communicate with, and report the measurements to, a remote server. One or more components of the system (e.g., the portable ketone measurement device, the mobile application, and/or the server) may, where appropriate, adjust the ketone measurements to compensate for ketone variations resulting from, e.g., the age of the user, a medical condition of the user, a missed medication event, or an interrupted sleep event. The application may, in some scenarios, withhold the display of a ketone measurement from the user until an authorization has been received from the server.

主权项

1. A system for measuring a ketone in a breath of a user, the system comprising:
a portable ketone measurement device that measures the ketone at a first location and generates a measurement signal indicative of the concentration of the ketone in a breath sample of the user, the portable ketone measurement device comprising a pump that moves the breath sample along a flow path to a ketone sensor, and comprising a wireless transceiver capable of wirelessly transmitting the measurement signal; a communications device located at the first location, the communications device configured to receive a wireless transmission of the measurement signal from the portable ketone measurement device, and to transmit the measurement signal; and a remote system disposed at a second location remote from the first location that receives the measurement signal from the communications device; at least one of the portable ketone measurement device, the communications device and the remote system comprising at least one processor that processes parameter data and generates a compensation factor for effecting a modification of the measurement signal to compensate for at least one of the following: (1) an age of the user, (2) a nutritional ketosis condition of the user, (3) a chronic obstructive pulmonary disease (COPD) condition of the user, (4) a missed medication event by the user, (5) an interrupted sleep condition of the user, (6) a diabetic ketoacidosis condition of the user.
