BREATH ANALYSIS DEVICE

摘要

A breath analysis device (10) comprising an inlet (11) for receiving a breath of a user, an analyzer (12) for determining a concentration of at least one element in the breath and output (15) for indicating the health zone corresponding to the concentration. The device also comprises a database for comprising previously determined concentrations and corresponding times at which the previously determined concentrations have been stored in the database and a processor (14) for storing in the concentrations in the database, comparing a measured concentration to at least one threshold for determining a health zone and recalculating the at least one threshold, based on the concentration and at least one of the previously determined concentrations.
