Abstract

The invention relates to a device for collecting gas. The inventive device contains at least one gas pump (12, 20, 98) and at least one gas storage device and preferably consists of a low-pressure system and a high-pressure system and is designed for humid gases (17). The inventive device can be used for collecting lost anaesthesia gases containing xenon and for recovering the xenon contained.
