A transportable pneumotachograph for the measurement of components of the expiration volume

摘要

The present invention relates to a transportable pneumotachograph for the determination of components in the expiration volume with a processor (4), a ausatemseitig pneumotachograph (1), which is mounted on the pressure (peep), - valve (5), a with inhalation pneumotachograph (1) mounted on the filter (6) for the removal of the proportion of to a determining component in the inspiration air, at least one in or on the pneumotachograph tube (2) mounted to the sampling (8), a sampling (8) with the valve (10), at least one sensor (7) for the determination of one of the components in the expiration volume and a down stream to the sensor (7) on the side of the pump (13), wherein between the valve (10) and the sensor (7) a chemically / physically modified hose (18), which from an air-conditioning chamber (15) for conditioning of the hose (18) sample gas, flowing through and / or calibration gas is enclosed, is set up and in the air-conditioning chamber (15) a defined gas atmosphere is adjustable, so that, by means of the air-conditioning chamber (15) the relative humidity and / or the temperature and / or the composition of the gas flowing through the hose (18) can be adjusted to predetermined parameters.
