Claim:
1. A regulation device for a source of breathable gas, comprising: a reaction medium comprising sodium chlorate having iron fillings, the reaction medium adapted to perform an exothermic reaction for production of oxygen, the reaction medium having an annular shape and surrounding an interior reaction volume having a reaction gas inlet and a first breathable gas outlet; a flow regulator arranged at the first breathable gas outlet and adapted to regulate a flow of oxygen through the first breathable gas outlet depending at least on a temperature of the regulation device and to throttle the flow of oxygen through the first breathable gas outlet if the temperature of the regulation device is increased; a rigid housing comprising a substantially tubular shape and comprising a second breathable gas outlet; and an exterior volume arranged radially outwardly between the reaction medium and an annular wall of the housing, the exterior volume surrounding the reaction medium radially, wherein the regulation device is adapted to direct a flow of reaction gas through the exterior volume towards the reaction gas inlet of the interior reaction volume.
