A portable device for generating oxygen by decomposition of hydrogen peroxide, comprising at least one hydrogen peroxide solution reservoir 21, a reactor for reacting the solution with a catalyst 23, a feeding system 22 to drive hydrogen peroxide into the reactor from the reservoir, a cooling system 26a,b connected to an outlet of the reactor to cool generated oxygen, a hydrophobic filter membrane 28 to remove water vapour at the oxygen outlet of said cooling system, and a flow regulator 29a-c to control the release of the oxygen from the generator. The cooling system may have a water collection tank 27 and drain. A catalytic filter may be located between the reactor and cooling system to remove hydrogen peroxide vapour. The reservoir may be configured as a removable cartridge. The generator may produce medical grade oxygen and have biofeedback sensors to control the regulator in response to a patient’s condition. |
