For the measurement and display of various parameters in condensates, contained in a single sample of exhaled breath, different sensors at the breath flow channel register them simultaneously and/or in sequence

摘要

To measure various parameters in condensates contained in exhaled breath, they flow over a number of different sensors. The sensors determine the sample parameters simultaneously and/or in sequence, and the measurements are shown on a display. The sensor measurements use electrochemical, optical and/or gravimetric methods. The different sensors (1a-1d) are in the flow channel (2) for the exhaled breath, on a common carrier (5), with one or more openings (3) into the channel to give part-flows to the sensors. The sensors have working electrodes (6) and reference electrodes (7). The system has biologically active coatings (8.1-8.4).
