Abstract
A portable oxygen generating system is provided that comprises a reaction chamber, a feed system for providing and controlling hydrogen peroxide solution to the reaction chamber, and a cooling/condensing system for cooling the hot oxygen and water vapor leaving the reactor and condensing and removing water. The portable chemical oxygen generation system produces humidified, breathable oxygen, that is substantially free of hydrogen peroxide and other contaminants, at a controlled flow and temperature over an extended period of time.
Core Innovation
The invention provides a portable oxygen generating device that includes a reaction chamber in which a catalyst facilitates chemical decomposition of hydrogen peroxide to oxygen and water. The reaction chamber has an inlet for introduction of a hydrogen peroxide solution and an outlet for release of oxygen and water vapor from the reaction chamber. A hydrogen peroxide feed system introduces the aqueous hydrogen peroxide solution into the reaction chamber, including a hydrogen peroxide reservoir that is a replaceable cartridge and a feed flow regulator that controls a rate of addition into the reaction chamber.
A cooling system receives the oxygen and water vapor from the reaction chamber outlet. The cooling system includes a condenser with two or more drains configured to drain condensed water. The device further includes an outlet for release of cooled oxygen gas with reduced water vapor, and one or more hydrophobic membranes situated after the cooling system, or situated between the reaction chamber and the cooling system, or both, to remove a portion of water from the gas flow comprising the oxygen.
The device also includes an electronic control unit that regulates a flow rate of oxygen from the device. In the disclosed configuration, the device generates a constant flow of oxygen up to at least about 8 L/min, at a temperature of less than about 40°C for more than about 30 minutes. The system architecture is described to support extended operation while reducing water vapor in the oxygen released from the device.
Claims Coverage
The independent claim set is centered on one independent claim (clm-00001). It specifies a portable oxygen generating device with a catalyst-based reaction chamber fed by a replaceable aqueous hydrogen peroxide cartridge, followed by cooling and condensing with a condenser having two or more drains and hydrophobic membrane water removal, plus electronic control to regulate oxygen flow. The claim includes the generation of a constant oxygen flow up to at least about 8 L/min at a temperature of less than about 40°C for more than about 30 minutes, capturing these key inventive features.
Catalyst-based reaction chamber for hydrogen peroxide decomposition
A reaction chamber comprising a catalyst that facilitates the chemical decomposition of hydrogen peroxide to oxygen and water, with an inlet for introduction of a hydrogen peroxide solution and an outlet for release of oxygen and water vapor.
Replaceable hydrogen peroxide reservoir with controlled feed rate
A hydrogen peroxide feed system in fluid communication with the inlet, comprising a hydrogen peroxide reservoir that contains aqueous hydrogen peroxide solution as a replaceable cartridge and a feed flow regulator that controls a rate of addition of the aqueous hydrogen peroxide solution into the reaction chamber.
Cooling condenser with multiple drains for condensed water
A cooling system comprising an inlet receiving the oxygen and water vapor, a condenser comprising two or more drains each configured to drain water condensed from the water vapor, and an outlet for release of cooled oxygen gas with reduced water vapor.
Hydrophobic membrane water removal from oxygen-containing gas
One or more hydrophobic membranes situated after the cooling system, or situated between the reaction chamber and the cooling system, or both, to remove a portion of water from the gas flow comprising the oxygen.
Electronic control unit for regulated oxygen flow
An electronic control unit that regulates a flow rate of oxygen from the device.
Constant oxygen output at elevated throughput and limited temperature
A device that generates a constant flow of oxygen up to at least about 8 L/min, at a temperature of less than about 40°C for more than about 30 minutes.
Across the independent claim, the inventive coverage is directed to a portable device that decomposes aqueous hydrogen peroxide in a catalyst-equipped reaction chamber, supplies the peroxide via a replaceable cartridge with a controlled feed flow, cools and condenses the resulting oxygen and water vapor using a condenser with multiple drains, removes residual water vapor using hydrophobic membranes, and achieves regulated constant oxygen flow under a temperature limit for an extended operating period.
Stated Advantages
