[The small Esssen high-pressure oxygen chamber for experimental animals (author's transl)].

A small translucent high-pressure chamber is introduced which has been exploited for local irradiation of tumour-bearing mice. The chamber has particularly proven to be valuable for high-pressure oxygen therapy together with simultaneous irradiation but can be used also for normal pressure and for gas other than oxygen. The chamber is shown during operation and a diagram illustrates design and technical data.
