DEVICE, SYSTEM, AND METHOD FOR PROVIDING A CALIBRATION FLUID FOR THE CALIBRATION AND QUALITY CONTROL OF A RESPIRATORY GAS ANALYSIS DEVICE

The invention relates to a device (100) for providing a calibration fluid, in particular a nitrogen oxide, for calibrating a respiratory gas analysis device (20), comprising a first interface (110) for connecting a chamber (101) of the device (100) to a measurement path (21) of the respiratory gas analysis device (20), a first opening (120) for introducing a reactant carrier (10) with a first reactant (11) into the chamber (101), and a contact element (140). The contact element (140) is arranged in the chamber (101) relative to the first opening (120) such that when the reactant carrier (10) is introduced, a contact of the contact element (140) with the reactant carrier (10) is facilitated in order to trigger a chemical reaction of the first reactant (11) so as to generate the calibrationfluid. The invention further relates to a system (1000), a reactant carrier (10), and a method (500) for providing a calibration fluid for calibrating a respiratory gas analysis device (20). 本发明涉及一种用于提供用于对呼吸气体分析机构（20）进行校准的校准流
