SENSOR MODULE FOR RESPIRABLE GAS MIXTURES, VENTILATOR, THERAPY DEVICE AND METHOD FOR MEASURING A PLURALITY OF GASES OF A RESPIRABLE GAS MIXTURE
First Claim
1. A sensor module for respirable gas mixtures, the sensor module comprising:
- at least one first sensor for measuring a gas with first sensor principles of measurement;
at least one second sensor for measuring a gas with second sensor principles of measurement, wherein at least one of the first sensor principles of measurement is different from at least one of the second sensor principles of measurement; and
an analysis unit configured to determine a gas measurement result as a function of the measurements of the first sensor and as a function of the measurements of the second sensor for measuring the same gas.

Abstract
A respirable gas mixture sensor module (10) includes a first sensor (1, 14-1, 14-2) for measuring a gas and a second sensor (18, 18-1, 18-2) for measuring the same gas and apply different principles of measurement. The sensor module (10) is configured to determine a measurement result for the gas taking into account the measurements. As an alternative the sensor module (10) includes a first sensor group (12) including a first sensor (14, 14-1, 14-2) and a second sensor group (16) including a second sensor (18, 18-1, 18-2), each for measuring both a first and a second gas and apply different principles of measurement. The sensor module is configured to determine measurement results for the gases, taking into account the respective measurements of the first and second sensors. A ventilator, a therapy device and a method for measuring a plurality of gases of a respirable gas mixture are also provided.
