Described herein are various embodiments of an oxygen concentrator system and method of delivering oxygen enriched gas to a user. In some embodiments, oxygen concentrator system includes one or more components that improve the efficiency of oxygen enriched gas delivery during operation of the oxygen concentrator system.

Method and systems for the delivery of oxygen enriched gas

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.

Oxygen concentrator apparatus and method having flow restricted coupling of the canisters

Described herein are various embodiments of an oxygen concentrator system. In some embodiments, oxygen concentrator system includes one or more components that improve energy usage during operation of the oxygen concentrator system.

Oxygen concentrator systems and methods

Described herein are various embodiments of an oxygen concentrator system that includes a home oxygen concentrator system couplable to a portable oxygen concentrator system.

Dual oxygen concentrator systems and methods

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. Coupling an oxygen concentration sensor to the generated oxygen enriched gas stream may allow monitoring of the purity of the produced gas.

Oxygen concentrator apparatus and method having an ultrasonic detector

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.

Oxygen concentrator apparatus and method having variable operation modes

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.

Oxygen concentrator pump systems and methods

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. During venting of the canisters, use of oxygen as a purge gas may improve the efficiency and lifetime of the oxygen concentrator.

Oxygen concentrator apparatus and method with an oxygen assisted venting system

Described herein are various embodiments of an oxygen concentrator system. In some embodiments, an oxygen concentrator system includes one or more components that improve dissipation of heat formed during operation of the oxygen concentrator system.

Oxygen concentrator heat management system and method

Described herein are various embodiments of an oxygen concentrator system In some embodiment, an oxygen concentrator system includes improved charging and battery control circuits.
