Abstract
A removable gas separation cartridge which includes a housing containing three columns, each having an inlet port, an outlet port, and a bed of adsorbent material. The cartridge is removable from an oxygen concentrator which separates oxygen from ambient air by using a vacuum swing absorption process.
Claims20
A removable gas separation cartridge for use in an oxygen concentrator which separates oxygen from ambient air by using a vacuum swing absorption process, the gas separation cartridge comprising:
- a first adsorbent column having an inlet, an outlet and a first bed of adsorbent material;
- a second adsorbent column having an inlet, an outlet and a second bed of adsorbent material;
- a third adsorbent column having an inlet, an outlet and a third bed of adsorbent material;
- a housing for containing the first, second, and third adsorbent columns;
- first, second, and third inlet ports in the housing connected to the respective first, second, and third column inlets;
- first, second, and third outlet ports in the housing connected to the respective first, second, and third column outlets.
A removable cartridge for a portable oxygen concentrator, the cartridge comprising:
- an outer casing;
- a plurality of gas separation columns within the outer casing, each gas separation column containing an adsorbent material that preferentially adsorbs nitrogen, a first end, and a second end;
- a plurality of inlet ports in the outer casing, each inlet port connect to the first end of one of the columns;
- and
- a plurality of outlet ports in the outer casing, each outlet port connected to the second end of one of the columns.
A removeable gas separation cartridge for use in an oxygen concentrator which separates oxygen from ambient air by using a vacuum swing absorption process, the gas separation cartridge comprising:
- a first adsorbent column having an inlet, and outlet and a first bed of adsorbent material;
- a second adsorbent column having an inlet, an outlet and a second bed of adsorbent material;
- a third adsorbent column having an inlet, and outlet and a third bed of adsorbent material;
- wherein each adsorbent column further comprise spin adjacent the inlet and outlet of the adsorption columns;
- a housing for containing the first, second, and third adsorbent columns;
- an inlet port in the housing connected to each of the respective first, second, and third column inlets;
- and
- an outlet port in the housing connected to each of the respective first, second, and third column outlets.
A removeable gas separation cartridge for use in an oxygen concentrator which separates oxygen from ambient air by using a vacuum swing absorption process, the gas separation cartridge comprising:
- a first adsorbent column having an inlet, and outlet and a first bed of adsorbent material;
- a second adsorbent column having an inlet, an outlet and a second bed of adsorbent material;
- a third adsorbent column having an inlet, and outlet and a third bed of adsorbent material;
- an inlet air filter;
- means for connecting the inlet air filter to the oxygen concentrator;
- a product gas filter;
- means for connecting the product gas filter to the oxygen concentrator;
- a housing for containing the first, second, and third adsorbent columns, the inlet filter, and the product gas filter;
- an inlet port in the housing connected to each of the respective first, second, and third column inlets;
- and
- an outlet port in the housing connected to each of the respective first, second, and third column outlets.
