Abstract: An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. The oxygen concentrator system may include one or more flow restrictors to allow controlled release of oxygen enriched gas between the canisters.

The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. Coupling an oxygen concentration sensor to the generated oxygen enriched gas stream may allow monitoring of the purity of the produced gas.

Abstract: An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. The oxygen concentrator system may operate in multiple modes, automatically determined or selected by the user, to take into account the different activity levels of the user.

Abstract: In some embodiments, a system and/or method may include a pouring spout assembly for a container. In some embodiments, the pouring spout assembly may include a first conduit, a second conduit, a third conduit, a fourth conduit, a handle, and a spout lock. The second conduit may be positionable, during use, in a distal end of the first conduit. The third conduit may be positionable, during use, in a proximal end of the first conduit. The fourth conduit may be coupled to the second conduit. When the second conduit is in a first position liquids and gases may be inhibited from being conveyed through the pouring spout assembly. When the second conduit is in a second position gases are allowed to convey through the pouring spout assembly. When the second conduit is in a third position liquids are allowed to convey through the pouring spout assembly.

Abstract: Oxygen concentrator apparatus and method of use are described herein. The oxygen concentration may include at least one canister; gas separation adsorbent disposed in at least one canister, and a compression system. The compression system may include at least one compressor coupled to the at least one canister. The compressor may include a first rotor comprising at least two projections and a second rotor comprising at least two recesses. During rotation of the first and second rotors, gas moves through the compressor to at least one of the canisters. In the canisters, gas separation adsorbent may separate at least some nitrogen from air produce oxygen enriched gas.
