BREATH ALCOHOL-MEASURING DEVICE, PROCESS AND SYSTEM

摘要

A device, a system and a process is provided for the use of a breath alcohol-measuring device ( 1 ) with improved personal identification. The breath alcohol-measuring device ( 1 ) is combined with a pulse oscillometer ( 4 ) such that the initially measured values of the complex airway resistance of a test subject are stored in an evaluating and control unit ( 3 ) connected to the breath alcohol-measuring device ( 1 ) and to the pulse oscillometer ( 4 ) and compared to subsequently measured values of a test subject. A breath alcohol measurement is released and/or a vehicle immobilizer ( 2 ) is actuated in case of agreement of stored values with subsequently measured values.
