ABSTRACT:
The invention relates to an automatically operating oxygen rescue apparatus whose case consists of a housing portion and a cover attached thereto, with the case holding an oxygen bottle, a regeneration cartridge, an oxygen metering valve system, and a breathing tube, with the housing portion having an impact device whose impact head can be made to contact the surface of the cover; the movable part of the impact device is operatively connected to the oxygen valve or to a valve on the oxygen bottle. The oxygen metering valve system contains lines for constant oxygen metering, automatic metering by a regulator and supplemental metering, all of which discharge into a breathing tube.
With the rescue apparatus of the invention, the impact device can be started with a single motion. Actuating the impact device causes not only the case to open, but also the release of oxygen. The triple oxygen metering is adapted to the needs of the escaping person and can secure optimum air supply during escape from disaster.
