Device for measuring gas analytes in breath gas, has inlet opening and line system which stands in fluid connection with inlet opening, where line system has branch

摘要

The device (1) has an inlet opening and a line system (3,5,7) which stands in fluid connection with the inlet opening, where the line system has a branch. The flow path is switched through the line system such that an arbitrarily selectable fraction of the tidal volume is conducted in a branch line will in a measuring chamber (11).
