APPARATUS FOR FIRE PROTECTION DURING THERAPY BY MEANS OF OXYGEN-ENRICHED RESPIRATORY GASES

摘要

The invention relates to an apparatus for supplying a patient with oxygen-enriched respiratory gas, having a fire protection device. The supply line of a region close to a patient has an enlarged flow resistance. The flow resistance of the region close to the patient is reduced under the effect of heat until the increase in volume flow thereby caused or the pressure drop thereby caused can be detected by a detector or sensor and/or directly leads to a closing of the valve.
