The invention relates to a self-contained device for generating high-pressure breathing oxygen, of the type comprising an oxygen-generating chemical candle (3), a gastight confinement chamber composed of a body (1) and of a cover (2), in which chamber the candle is housed, means of igniting the candle, means of percussing the igniter and means of filtering the oxygen generated, characterized in that the igniting means consist of a compressed mixture of titanium and boron and in that the filtering means consist of a mixture of lime or soda lime and of molecular sieve and are distributed, on the one hand, packed in around the candle and, on the other hand, in a cartridge having a generated-oxygen outlet cap. Application to the generation of oxygen in the medical or paramedical field, the aeronautics field and the military field.
This disclosure is directed to a backpack comprising a frame with straps and surrounding side wall for easy attachment on a diver. A first gas storage tank stores either oxygen or air, which is input through an inlet line. With a pressure regulator, it delivers a flow of gas to feed the diver while diving. As the pressure drops in the gas tank, a secondary source of oxygen is then operated and delivers a flow of oxygen to the diver so that the diver is able to receive supplemental oxygen stored in the gas storage tank formed by electric current flowing through a pair of spaced terminals. The terminals form oxygen by disassociation of water. The oxygen is bubbled upwardly in a chamber, pass though a hydrophobic valve, delivered into the gas storage tank, and supplements the oxygen supply.
The invention is a portable, non-pressurized oxygen generation device. A first chamber holds an oxygen liberating chemical, and a catalyst from a second chamber begins the oxygen liberating reaction when the two chemicals mix. The chemicals are pre-measured, and oxygen generation can begin within seconds of activation.
