The various embodiments of the present invention disclose a modular portable oxygen generator including a reactor container having two vertical compartments, where one of the compartments houses a cartridge while another houses oxygen storage tank. The arrangement is provided with a mechanism to guide the oxygen generated in the cartridge after triggering to a defined outlet. The modular portable oxygen generator is light weight, easy to carry and easy to use with minimal maintenance as compared to heavy oxygen cylinders and generator.

An oxygen generator includes a bag body and supporting components. The bag body is configured to contain a reactive liquid, a reactant and a catalyst, and the bag body includes a bag piece, a circumferential sealing part and separation parts. The circumferential sealing part is bound with a part of the periphery of the bag piece, so as to define a range of an inner space, and a range of the rest part of the periphery of the bag piece defines an opening. Both ends of each separation part are connected to the circumferential sealing part so as to separate the inner space into a plurality of separate spaces, and the plurality of separate spaces respectively contain the reactant and the catalyst. The supporting components are contained in one of the plurality of separate spaces, and the positions, corresponding to the supporting components, of the bag body are incompressible.

Various systems and devices for generating nitric oxide are disclosed herein. According to one embodiment, the device includes a body having an inlet, an outlet, and a porous solid matrix positioned with the body. The porous solid matrix is coated with an aqueous solution of an antioxidant, wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the solid matrix to convert nitrogen dioxide in the gas flow into nitric oxide. The porous solid matrix allows the device to be used in any orientation. Additionally, the porous solid matrix provides a rigid structure suitable to withstand vibrations and abuse without compromising device functionality.

A portable chemical oxygen generator for delivering oxygen to a patient is described. The generator includes a housing containing a reaction chamber. Within the reaction chamber is a quantity of a peroxide adduct. A valve is provided with a lower portion of the valve in fluid communication with the reaction chamber. An upper portion of the valve is in fluid communication with a reservoir that holds a quantity of an aqueous solution. An internal chamber is formed within the valve by releasable seals that separate the internal chamber from the upper portion of the valve and a lower portion of the valve. The internal chamber holds a quantity of a peroxide-decomposing catalyst. The generator also includes a valve actuator. Operation of the valve actuator releases the seals in the valve and creates a fluid path from the reservoir through the internal chamber into the reaction chamber. When the valve is actuated, the aqueous solution flows from the reservoir through the internal chamber and into the reaction chamber. This flow washes the catalyst into the reaction chamber along with the aqueous solution. The solution and catalyst mix with the peroxide adduct and cause an oxygen-generating reaction.
